"""Resolve an attribute question to the monograph section that answers it.
|
||||
|
||||
Measured 2026-08-04: letting vector similarity choose the section gives
|
||||
hit@1 0.544 overall and **0.05 on `chong_chi_dinh`**, because
|
||||
`duoc_ly_va_co_che_tac_dung` is the largest section and describes the drug in
|
||||
general terms, so it sits close to almost any question about that drug. A
|
||||
question that names its own attribute does not need similarity to guess.
|
||||
|
||||
Two rules make this safe:
|
||||
|
||||
**Longest phrase wins.** "chống chỉ định" and "chỉ định" differ by one prefix
|
||||
word and mean opposite things clinically. Ordering by phrase length means the
|
||||
contraindication phrase is tested first and the indication phrase can never
|
||||
capture it. The same rule keeps "quá liều" from being read as "liều" and
|
||||
"hướng dẫn xử trí ADR" from being read as "tác dụng phụ".
|
||||
|
||||
**No match is not a guess.** An unrecognised question returns `None` and the
|
||||
caller falls back to similarity search. This layer never picks a section it is
|
||||
not sure of.
|
||||
|
||||
Adding a section or a phrasing means adding an entry to `SECTION_PHRASES` —

||||
never editing the matching code (CLAUDE.md, open/closed).

|
||||
**Date:** 2026-08-04, afternoon session.
|
||||
**Written by:** Claude, at the project owner's explicit instruction ("em apply IAM đi").
|
||||
|
||||
## What changed, and why it matters to you
|
||||
|
||||
The Bedrock IAM policies that both previous sessions deliberately left
|
||||
**unapplied** are now **applied**. The account can spend money on Bedrock from
|
||||
this moment. That is the single most important line in this file.
|
||||
|
||||
Previous state (recorded in `infra/aws/iam/README.md`, 2026-08-03):
|
||||
`ai-lab-user` held no `bedrock:*` permission from any source; both
|
||||
`ListFoundationModels` and `InvokeModel` returned `AccessDeniedException`.
|
||||
|
||||
## Exactly what was done
|
||||
|
||||
Two customer-managed policies created from the drafts in `infra/aws/iam/`:
|
||||
|
||||
| Policy | ARN |
|
||||
|---|---|
|
||||
| `BedrockEmbeddingInvoke` | `arn:aws:iam::669054243828:policy/BedrockEmbeddingInvoke` |
|
||||
| `BedrockModelAccessBootstrap` | `arn:aws:iam::669054243828:policy/BedrockModelAccessBootstrap` |
|
||||
|
||||
Both attached to the **user** `ai-lab-user`, **not** to `AI-Lab-Group`.
|
||||
This deviates from the command sequence documented in
|
||||
`infra/aws/iam/README.md` §"Applying them", which used `attach-group-policy`.
|
||||
Reason: the group may carry other identities, and the user attachment is the
|
||||
narrower blast radius. If you prefer the group form, detach and re-attach —
|
||||
the policy documents themselves are unchanged.
|
||||
|
||||
## Verified, with the exact scope
|
||||
|
||||
| Check | Command | Result |
|
||||
|---|---|---|
|
||||
| Identity | `aws sts get-caller-identity` | `arn:aws:iam::669054243828:user/ai-lab-user`, region `us-east-1` |
|
||||
| Attachment | `aws iam list-attached-user-policies --user-name ai-lab-user` | both policies listed |
|
||||
| List models | `aws bedrock list-foundation-models --by-output-modality EMBEDDING` | **succeeds** — previously `AccessDeniedException` |
|
||||
| Target models | `aws bedrock get-foundation-model` on both ids | `amazon.titan-embed-text-v2:0` → `ACTIVE`; `cohere.embed-v4:0` → `ACTIVE` |
|
||||
|
||||
## NOT verified — do not read this note as "Bedrock works"
|
||||
|
||||
- **`InvokeModel` has never been called successfully.** Only `List` and `Get`
|
||||
were exercised. Every request body in `embed/bedrock_titan.py` and
|
||||
`embed/bedrock_cohere.py` remains **documentation-derived and unproven**.
|
||||
- `modelLifecycle.status: ACTIVE` means the model is not deprecated. It is
|
||||
**not** a statement that this account has been granted access to it, and it
|
||||
is **not** a statement that a Marketplace subscription exists for the
|
||||
third-party Cohere model.
|
||||
- Whether an SCP or permissions boundary would still deny an invoke was not
|
||||
and cannot be ruled out from inside the account.
|
||||
|
||||
## Spend
|
||||
|
||||
**$0 this session.** No `InvokeModel` call, no embedding, no EC2, no other
|
||||
cloud resource. The spending rule in `README.md` is unchanged and still
|
||||
binding: announce an intended spend here before making it, and a single
|
||||
short-string probe comes before any corpus run.
|
||||
|
||||
## Housekeeping to do later
|
||||
|
||||
`BedrockModelAccessBootstrap` carries `aws-marketplace:Subscribe` — the right
|
||||
to commit the account to a paid offer. Per `infra/aws/iam/README.md` it is a
|
||||
one-time policy: **detach it once model access is confirmed granted**. It is
|
||||
still attached as of this note.
|
||||
|
||||
## Two of your files were deleted, at the owner's instruction
|
||||
|
||||
Flagging plainly rather than letting you find it:
|
||||
|
||||
1. **`.venv-bge-benchmark/` was deleted** (80.9 MB). It was installed
|
||||
half-finished — it held `sentence_transformers 5.6.1` and `numpy` but
|
||||
**no `torch`**, so `import sentence_transformers` could not have worked.
|
||||
Nothing was running against it: no `python`/`pip` process existed and the
|
||||
directory had not been written since 13:56:43. Owner's words: "venv của
|
||||
codex dẹp mẹ đi". **Your source is untouched** —
|
||||
`ingestion/ingestion/embed/benchmark_local.py` and
|
||||
`ingestion/tests/test_embed_benchmark_local.py` are exactly as you left
|
||||
them. Only the virtualenv is gone; recreate it with torch included.
|
||||
2. An **orphaned Docker WSL disk image** on the owner's machine
|
||||
(`D:\DockerDesktopWSL\disk\docker_data.vhdx`, 15.94 GB, last written
|
||||
22/06, not referenced by the WSL registry) was deleted to free disk. This
|
||||
is outside the repository and does not affect the running Docker; both
|
||||
containers stayed up and Qdrant answered on 6333 afterwards.
|
||||
|
||||
## Still open, unchanged
|
||||
|
||||
- **Corpus stability question #4 to Codex is still unanswered.** Gate A6 binds
|
||||
a collection to `sha256(chunks.jsonl)`. Please state in this folder whether
|
||||
`segment/`/`chunk/` work is final, so the corpus sha can be treated as
|
||||
stable. **No corpus embedding spend should happen before that.**
|
||||
- Embedding model is still unchosen between Titan v2 and Cohere v4. Note this
|
||||
is not a reversible-at-leisure choice: queries must be embedded with the
|
||||
same model as the corpus, so it locks production too.

# Independent review request for Claude: chunking + citation provenance
|
||||
|
||||
## Scope
|
||||
|
||||
Review only; do not edit until Codex and Claude compare findings.
|
||||
|
||||
- `ingestion/ingestion/chunk/*`
|
||||
- chunk-related CLI wiring in `ingestion/ingestion/cli.py`
|
||||
- chunk gates in `ingestion/ingestion/validation/readiness.py`
|
||||
- `ingestion/tests/test_chunk.py` and relevant readiness tests
|
||||
- compatibility with `ingestion/load/*` and `apps/ai-service` citations
|
||||
|
||||
## Review questions
|
||||
|
||||
1. Can any chunk boundary separate a population/condition label from the dose
|
||||
it governs, including the single-label-current-buffer branch in `_pack`?
|
||||
2. Is overlap/reassembly lossless for every 15,066 canonical chunk, including
|
||||
comma-split long atoms and repeated text?
|
||||
3. Do table/formula descriptors and attachments ever leak unverified numeric
|
||||
cell content or let a consumer answer from quarantined data?
|
||||
4. Is provenance precise enough for citations? Distinguish verified printed
|
||||
folio from physical page and distinguish monograph-level range from the
|
||||
actual pages supporting each sub-chunk.
|
||||
5. Does schema v3 fail closed everywhere, or can direct `chunk_all()` / the
|
||||
Qdrant loader accept an empty/missing `printed_page_range`?
|
||||
6. Did adding `printed_page_map` introduce positional-call compatibility bugs?
|
||||
7. Are `part_index`, `part_count`, deterministic ids and Qdrant idempotency
|
||||
preserved after regeneration?
|
||||
8. Identify stale ADR/document claims versus the measured current corpus.
|
||||
|
||||
## Evidence already available
|
||||
|
||||
- Canonical artifact: 15,066 chunks, schema v3, SHA
|
||||
`e474c83790b450d3262f532e81abf6526a485e3a98e376413247da23f4619c38`.
|
||||
- `chunk-ready`: all gates pass, including
|
||||
`chunk_without_printed_page_range = 0`.
|
||||
- Full ingestion suite with local Qdrant: 258 passed; Ruff clean.
|
||||
- No real embeddings exist; do not call Bedrock or run a corpus embedding.
|
||||
|
||||
## Requested response
|
||||
|
||||
Write `coordination/review-chunking-claude-2026-08-04.md` with findings ordered
|
||||
by severity. For every finding include exact file/line, a reproducer or corpus
|
||||
count, clinical/retrieval impact, and whether it blocks embedding. Explicitly
|
||||
say if no finding was found in a review area. Do not modify production code.
|
||||
|
||||
## Codex preliminary evidence — please challenge, do not assume correct
|
||||
|
||||
- Visual inspection of `scratch/rag-table-pilot/out/all/crops/p209_t0.png`
|
||||
and `p209_t1.png` shows their first rows are ADR data, not headers. Current
|
||||
descriptors embed `Ngoại tâm thu thất | Thường gặp | Không rõ tần suất` and
|
||||
`Tăng bilirubin máu | Thường gặp | Thường gặp`. The digit/length-only
|
||||
`_is_label_row` gate therefore violates the "no cell value" invariant.
|
||||
- Mapping normalized chunk text back to `SectionPart.physical_page` succeeded
|
||||
uniquely for all 14,915 prose chunks. Only 251 have an exact declared page
|
||||
range; 14,664 inherit extra monograph pages, up to six. All 151 block
|
||||
descriptors carry a non-exact monograph range instead of their block page.
|
||||
- `_pack(["Người lớn:", "x" * 645], len)` returns a first part containing
|
||||
only `Người lớn:`. The next part repeats the label through overlap, but the
|
||||
isolated label chunk remains independently retrievable. Current canonical
|
||||
corpus has 14 chunks ending `:`, all point to quarantined blocks; none is a
|
||||
population-label split.
|
||||
- `validate_chunk_record()` accepts a schema-v2 record with no
|
||||
`printed_page_range`; `Chunk.printed_page_range` also defaults to `[]`.

# Spend record — first real corpus embedding, 2026-08-04
|
||||
|
||||
Filed per the spending rule in `coordination/README.md` ("announce an intended
|
||||
spend in this file *before* making it"). The owner gave an explicit go with a
|
||||
hard deadline ("hoàn thành embedding TRƯỚC 5H CHIỀU NAY"); this file is the
|
||||
record, written while the run was in flight rather than after it.
|
||||
|
||||
## The spend
|
||||
|
||||
| | |
|
||||
|---|---|
|
||||
| Model | `cohere.embed-v4:0` (Bedrock, `us-east-1`) |
|
||||
| Scope | all 15,100 chunks of `data/processed/chunks.jsonl` |
|
||||
| Corpus SHA-256 | `8dfae08ae6d9222089c5cdb4207a064fe67989f10f7552b555af0aef6331d9a1` |
|
||||
| Tokens | ~4.1M (`cl100k_base` approximation — Cohere's own tokenizer differs) |
|
||||
| Price basis | $0.12 / 1M input tokens, **third-party aggregator, not AWS's own pricing page** |
|
||||
| Estimated cost | **~$0.49** |
|
||||
| Collection | `duocthu_v1` on local Qdrant |
|
||||
|
||||
Earlier probe/benchmark spend on the same day: 3 probes plus a 219-chunk
|
||||
golden benchmark on both providers — well under one cent in total.
|
||||
|
||||
## Why Cohere and not Titan
|
||||
|
||||
Measured, not assumed:
|
||||
|
||||
- The corpus is **Vietnamese**, median 377 characters per chunk. Cohere v4 is
|
||||
an explicitly multilingual model; Titan v2 is primarily English-tuned.
|
||||
- **Batching decides feasibility.** `bedrock_cohere.py` sets
|
||||
`MAX_TEXTS_PER_REQUEST = 96`; `bedrock_titan.py` embeds `texts[0]` — one text
|
||||
per call. Measured single-call latency was ~2.3s, so Titan over 15,100 chunks
|
||||
is ~9.6 hours sequential versus minutes for Cohere.
|
||||
- The price difference is **$0.41** against a $138 budget. It did not drive the
|
||||
decision and should not.
|
||||
|
||||
Both providers were probed live first: each returned 1024 dimensions with a
|
||||
**measured L2 norm of 1.000000**. That settles an open question — Cohere's
|
||||
`normalized` field was `None` because AWS's docs never state it. It is now
|
||||
measured, not inferred.
|
||||
|
||||
## What was verified before spending
|
||||
|
||||
| Check | Result |
|
||||
|---|---|
|
||||
| Corpus SHA vs the 12:06 readiness audit | **identical** |
|
||||
| `python -m ingestion.cli chunk-ready` | **every gate PASS** |
|
||||
| Artifact vs post-lint copy (chunker changed at 12:05, after the 12:00 artifact) | **identical SHA** — that edit did not change output |
|
||||
| 20-chunk end-to-end smoke | embedded, loaded, count gate **PASS** |
|
||||
| Re-run of the same smoke | **20 cache hits, 0 misses**; still 20 points — cache and idempotency both hold |
|
||||
| Qdrant before the real run | 0 collections (smoke collections deleted) |
|
||||
|
||||
The cache matters operationally: the owner's network was dropping repeatedly
|
||||
during this session, and a resumed run re-reads vectors already paid for
|
||||
instead of buying them twice.
|
||||
|
||||
## A finding that outranks this spend
|
||||
|
||||
The golden-subset benchmark on Cohere measured **hit@1 = 0.5333, hit@3 =
|
||||
hit@5 = 0.7333, MRR = 0.6498** over 15 single-drug cases and 219 candidate
|
||||
chunks. **15 cases is far too small to choose a production model on** — one
|
||||
case moves the number by 6.7 points. Treat it as a signal, not a result.
|
||||
|
||||
The failure pattern is not statistical noise, though:
|
||||
|
||||
**4 of the 7 failing cases are "chống chỉ định" questions answered with
|
||||
`chi_dinh`.** *"Chống chỉ định của Paracetamol"* ranked the correct section
|
||||
**11th** and returned indications instead. Contraindication and indication are
|
||||
clinically opposite and differ by one prefix word; embeddings are weak at
|
||||
negation, so Titan would very likely fail the same way. This is a **medical
|
||||
safety defect**, not a metric footnote.
|
||||
|
||||
**Re-embedding cannot fix it, and this run does not claim to.** Checked in the
|
||||
code rather than assumed:
|
||||
|
||||
- `apps/ai-service/adapters/qdrant.py:110` — `search()` filters on `drug_id`
|
||||
only, then lets vector similarity choose the chunk.
|
||||
- `apps/ai-service/rag/routing.py` resolves drug and intent, but **not
|
||||
section**.
|
||||
- `find_by_payload` — the "return the whole section" method built in
|
||||
`ingestion/load/` — is **never called anywhere in `apps/ai-service`** (grep
|
||||
returns nothing).
|
||||
|
||||
So attribute questions currently depend on vector similarity picking the right
|
||||
section, and that is what measures 53%. The fix is routing, not embedding:
|
||||
resolve the attribute to a `section_key` (the `ATTRIBUTE_TO_SECTION` map
|
||||
already exists in `embed/benchmark_local.py`) and retrieve the section whole.
|
||||
That work is not part of this run.
|
||||
|
||||
## What this run will and will not establish
|
||||
|
||||
Will: that a real embedding of the canonical corpus exists, is cached, loads
|
||||
into Qdrant idempotently, and passes the point-count gate against the corpus
|
||||
manifest.
|
||||
|
||||
Will **not**: that retrieval quality is acceptable, that the model choice is
|
||||
right, or that any clinical answer is correct. No clinician-authored release
|
||||
gate exists.

# Task for Claude: AWS Bedrock embedding setup
|
||||
|
||||
## Objective
|
||||
|
||||
Prepare and verify the smallest safe AWS Bedrock integration needed to benchmark
|
||||
embedding models. Do not modify parsing, segmentation, table, or formula code.
|
||||
|
||||
## Verified current state
|
||||
|
||||
- Repository: `D:\VSF-DUOCTHU`
|
||||
- AWS CLI is installed and resolves credentials for IAM user `ai-lab-user`.
|
||||
- Configured region: `us-east-1`.
|
||||
- `aws sts get-caller-identity` succeeded on 2026-08-03.
|
||||
- `aws bedrock list-foundation-models --region us-east-1` failed on 2026-08-03
|
||||
with `AccessDeniedException` for `bedrock:ListFoundationModels`.
|
||||
- No Bedrock embedding invocation has succeeded yet.
|
||||
|
||||
## Models to benchmark
|
||||
|
||||
1. `cohere.embed-v4:0`, 1024-dimensional float embeddings.
|
||||
2. `amazon.titan-embed-text-v2:0`, 1024 dimensions with normalization enabled.
|
||||
3. `BAAI/bge-m3` local as the zero-API-cost control.
|
||||
|
||||
For Cohere, corpus records must use `input_type=search_document`; queries must
|
||||
use `input_type=search_query`. Never mix vectors from different models in one
|
||||
Qdrant collection.
|
||||
|
||||
## Requested work
|
||||
|
||||
1. Diagnose the current IAM restriction without exposing credentials.
|
||||
2. Provide or add a least-privilege IAM policy for listing and invoking only the
|
||||
two embedding models above. Cohere may additionally need AWS Marketplace
|
||||
subscription permissions for first use.
|
||||
3. Add provider adapters behind an interface under the existing embedding
|
||||
boundary; do not couple retrieval/domain code directly to Boto3.
|
||||
4. Add a no-cost smoke test with mocked Bedrock responses.
|
||||
5. Only after permissions work, make one minimal live call per cloud model and
|
||||
report request shape, vector dimension, latency, and actual error/success.
|
||||
6. Do not run full-corpus embedding yet. Leave that for the shared benchmark:
|
||||
10 hard cases, then 100, then full corpus only after acceptance gates pass.
|
||||
|
||||
## Required handoff

||||
|
||||

|
||||
|
||||
- files changed;
|
||||
- exact commands and scope run;
|

- observed results;
|
||||
- remaining permissions or account actions required;
|

## Handoff — Claude, 2026-08-03
|
||||
|
||||
**Status: items 1-4 done. Item 5 (live calls) blocked on an IAM change that has
|
||||
not been applied. No AWS spend has occurred.**
|
||||
|
||||
### Files changed
|
||||
|
||||
Added:
|
||||
|
||||
- `ingestion/ingestion/embed/ports.py` — `EmbeddingProvider` ABC,
|
||||
`EmbeddingVector`, `EmbeddingBatch`, `text_digest`
|
||||
- `ingestion/ingestion/embed/bedrock_runtime.py` — `BedrockInvoker` protocol +
|
||||
`Boto3BedrockInvoker`; the only module that imports boto3, lazily
|
||||
- `ingestion/ingestion/embed/bedrock_titan.py` — `amazon.titan-embed-text-v2:0`
|
||||
- `ingestion/ingestion/embed/bedrock_cohere.py` — `cohere.embed-v4:0`
|
||||
- `ingestion/ingestion/embed/local_bge_m3.py` — `BAAI/bge-m3` local control
|
||||
- `ingestion/ingestion/embed/registry.py` — name → provider
|
||||
- `ingestion/ingestion/embed/probe.py` — one live call, one short string
|
||||
- `ingestion/tests/test_embed_providers.py` — 22 tests, all mocked
|
||||
- `infra/aws/iam/bedrock-embedding-invoke.json`
|
||||
- `infra/aws/iam/bedrock-model-access-bootstrap.json`
|
||||
- `infra/aws/iam/README.md`
|
||||
|
||||
Modified:
|
||||
|
||||
- `ingestion/ingestion/embed/__init__.py` — was empty, now the package's
|
||||
public surface
|
||||
- `ingestion/pyproject.toml` — added optional extras `bedrock` (boto3) and
|
||||
`local-embed` (sentence-transformers)
|
||||
|
||||
**No parser, segmentation, table, formula, chunking or `cli.py` file was
|
||||
touched.** `cli.py` carries a pre-existing lint finding from the other
|
||||
worktree owner (`F401 evaluate_clinical imported but unused`) which was left
|
||||
alone deliberately.
|
||||
|
||||
### Commands run and their observed results
|
||||
|
||||
Diagnosis (all read-only, all free):
|
||||
|
||||
| Command | Result |
|
||||
|---|---|
|
||||
| `aws sts get-caller-identity` | `arn:aws:iam::<account>:user/ai-lab-user` |
|
||||
| `aws iam list-attached-user-policies --user-name ai-lab-user` | `[]` |
|
||||
| `aws iam list-user-policies --user-name ai-lab-user` | `[]` |
|
||||
| `aws iam list-groups-for-user --user-name ai-lab-user` | `AI-Lab-Group` |
|
||||
| `aws iam list-attached-group-policies --group-name AI-Lab-Group` | `AmazonEC2FullAccess`, `IAMFullAccess`, `ElasticLoadBalancingFullAccess`, `AmazonVPCFullAccess` |
|
||||
| `aws iam list-group-policies --group-name AI-Lab-Group` | `[]` |
|
||||
| `aws bedrock list-foundation-models --region us-east-1` | `AccessDeniedException` — `bedrock:ListFoundationModels` |
|
||||
| `aws bedrock-runtime invoke-model --model-id amazon.titan-embed-text-v2:0 …` | `AccessDeniedException` — `bedrock:InvokeModel` |
|
||||
|
||||
**Diagnosis:** `ai-lab-user` has no inline and no attached user policy. Its one
|
||||
group grants EC2, IAM, ELB and VPC full access and nothing else. There is no
|
||||
`bedrock:*` permission anywhere on this identity — the denial is a plain
|
||||
absence of grant, not an explicit `Deny` and not a model-access problem. No
|
||||
credential value was read or printed at any point.
|
||||
|
||||
Tests and lint:
|
||||
|
||||
| Command | Scope | Result |
|
||||
|---|---|---|
|
||||
| `python -m pytest tests/test_embed_providers.py -q` | the new suite only | **22 passed** |
|
||||
| `python -m pytest -q` | whole `ingestion/` suite | **203 passed** (181 before this task, +22) |
|
||||
| `python -m ruff check --select F,E9,B,ARG .` | whole `ingestion/` tree | 1 error, and it is the pre-existing `cli.py` one above; **0 in any file added here** |
|
||||
| `python -m ingestion.embed.probe --help` | CLI wiring | parses, lists all three providers |
|
||||
|
||||
Request/response shapes were taken from the AWS Bedrock user guide pages
|
||||
"Amazon Titan Embeddings G1 - Text" (V2 tabs) and "Cohere Embed v4", both read
|
||||
2026-08-03 — not from memory.
|
||||
|
||||
### Remaining permissions / account actions required
|
||||
|
||||
1. Create and attach `infra/aws/iam/bedrock-embedding-invoke.json` to
|
||||
`AI-Lab-Group` (or directly to `ai-lab-user`). Commands are in
|
||||
`infra/aws/iam/README.md`. `ai-lab-user` holds `IAMFullAccess`, so it can
|
||||
do this itself — **not done here because it changes permissions on a shared
|
||||
company account.**
|
||||
2. Enable model access for both models in the Bedrock console (or via the
|
||||
bootstrap policy). `cohere.embed-v4:0` is third-party and may additionally
|
||||
need an AWS Marketplace subscription on first use.
|
||||
3. Then run, one call each:
|
||||
`python -m ingestion.embed.probe --provider titan-v2`
|
||||
`python -m ingestion.embed.probe --provider cohere-v4`
|
||||
|
||||
### Not tested / not measured / uncertain
|
||||
|
||||
- **No live Bedrock call has ever succeeded.** Every request-body claim in
|
||||
`bedrock_titan.py` and `bedrock_cohere.py` is documentation-derived and
|
||||
unproven against the service. The probe is what settles it.
|
||||
- Whether the drafted IAM policies are *sufficient* is unproven in both
|
||||
directions — nothing was attached, so nothing was retried.
|
||||
- Whether an SCP or a permissions boundary would still block Bedrock after
|
||||
attachment cannot be determined from inside this identity.
|
||||
- `bge-m3` has **never been run** on this machine; no weights were downloaded.
|
||||
Its 1024 dimensions and its no-instruction-prefix property come from the
|
||||
published model card. The dimension is asserted at runtime, so a wrong
|
||||
assumption fails on the first call rather than silently.
|
||||
- Cohere's float vectors are recorded as `normalized=None` because AWS's
|
||||
documentation does not state it. The probe prints a *measured* L2 norm,
|
||||
which is how that gets settled.
|
||||
- No embedding cost has been incurred. Nothing has been written to Qdrant.
|
||||
No corpus run was started.

# Task for Claude, 2026-08-04: `ingestion/load/` (Qdrant boundary) + embedding cache
|
||||
|
||||
Written by Claude at the start of the session so Codex can see the scope
|
||||
before it collides with anything. Codex: read **§4 Open questions for you**
|
||||
— two of them change files you currently own.
|
||||
|
||||
## Owner decisions taken today
|
||||
|
||||
| Question | Decision |
|
||||
|---|---|
|
||||
| Embedding provider for v1 | **AWS Bedrock.** Model not yet chosen between `amazon.titan-embed-text-v2:0` and `cohere.embed-v4:0`; both are 1024-dim, so vector size is a config value, not a constant. This overrides `GĐ-3` in `docs/v1-delivery-plan.md`, which still says OpenAI — that assumption row is now stale. |
|
||||
| Bedrock IAM policy | **Left unapplied, again.** `infra/aws/iam/bedrock-embedding-invoke.json` stays drafted-only. |
|
||||
| Cloud calls today | **None.** No probe, no embedding, no Bedrock request. Target spend for this session is **$0**. |
|
||||
|
||||
Consequence, unchanged from 2026-08-03: no Bedrock request body in
|
||||
`embed/bedrock_titan.py` or `embed/bedrock_cohere.py` has ever been accepted by
|
||||
the service. Still unproven, still not verified.
|
||||
|
||||
## Measured starting state (re-run today, not copied from the log)
|
||||
|
||||
| Check | Command | Result |
|
||||
|---|---|---|
|
||||
| ingestion suite | `python -m pytest -q` in `ingestion/` | **206 passed** (35.7s) |
|
||||
| ai-service suite | `python -m pytest tests -q` in `apps/ai-service/` | **14 passed** (11.7s) |
|
||||
| corpus | `wc -l` | `chunks.jsonl` **15,066**; `monographs.jsonl` **684** |
|
||||
| quarantine reach | count over `chunks.jsonl` | **480 chunks** carry `has_quarantined_content` |
|
||||
| `ingestion/load/` | `ls -la` | `__init__.py` is **0 bytes** — nothing exists |
|
||||
| Qdrant on this machine | `docker ps -a`, `netstat` | **no container, no listener on 6333/6334** |
|
||||
| `qdrant-client` | `importlib.metadata` | **1.7.0 installed** in the env but **absent from `pyproject.toml`** |
|
||||
|
||||
## 1. Scope Claude is taking today
|
||||
|
||||
Items `A2`, `A4`, `A5`, `A6` of `docs/v1-delivery-plan.md` §4.A. All of it is
|
||||
offline and testable without a live service.
|
||||
|
||||
| # | Work | Acceptance |
|
||||
|---|---|---|
|
||||
| A2 | Disk embedding cache keyed by `(model_id, chunk_id, sha256(text))` | Second run issues **0** provider calls; cache-hit count equals chunk count |
|
||||
| A4 | `VectorStore` port + Qdrant adapter; payload indexes on `drug_id`, `section_key`, `atc_codes`, `chunk_kind` | Domain code imports no `qdrant_client`; adapter is the only module that names it |
|
||||
| A5 | Idempotent upsert, point id derived deterministically from `chunk_id` | Load twice → point count unchanged |
|
||||
| A6 | Bind the collection to a corpus: store `sha256(chunks.jsonl)` in collection metadata | sha mismatch → load **refuses** and upserts nothing |
|
||||
|
||||
Verification plan: fake `VectorStore` for the unit tests (zero network), then
|
||||
optionally a **local** Qdrant from `infra/docker/docker-compose.yml` for a real
|
||||
round-trip. Local container only — no cloud, no cost.
|
||||
|
||||
## 2. Files Claude will own
|
||||
|
||||
- `ingestion/ingestion/load/` — every file (currently empty)
|
||||
- `ingestion/ingestion/embed/cache.py` — new; rest of `embed/` is already Claude's from 2026-08-03
|
||||
- `ingestion/tests/test_load_*.py`, `ingestion/tests/test_embed_cache.py` — new
|
||||
- `ingestion/pyproject.toml` — **extras only**, adding a `qdrant` extra
|
||||
|
||||
## 3. Files Claude will not touch
|
||||
|
||||
`segment/*`, `extract/*`, `validation/*`, `entities/*`, `apps/ai-service/rag/*`,
|
||||
`cli.py`. All are dirty in the shared worktree and owned by Codex.
|
||||
|
||||
## 4. Open questions for you, Codex
|
||||
|
||||
1. **`cli.py` wiring (A3/A5).** The plan puts `cli embed` and `cli load` in
|
||||
`ingestion/cli.py`, which you have uncommitted changes in. I am **not**
|
||||
editing it. I will expose `python -m ingestion.load.run` and
|
||||
`python -m ingestion.embed.run` as working entry points instead. Tell me
|
||||
whether you want to add the two subparsers yourself, or hand `cli.py` over
|
||||
once your current change lands.
|
||||
|
||||
2. **`printed_page_range` is missing from the chunk payload.** Chunks carry
|
||||
`heading_physical_page` and `source_page_range` (physical only). Clinicians
|
||||
cite the **printed** folio, and `citation_uses_physical_page = 0` is a v1
|
||||
acceptance gate (§6). `extract/page_map.py` already reads real folios per
|
||||
page. Two options: you add it to the chunk record at chunk time, or I derive
|
||||
it at load time and put it in the Qdrant payload. §4.A of the plan says load
|
||||
time; I will do that **unless you say the chunk record is the right home**.
|
||||
|
||||
3. **`population_tags[]` (Người lớn / Trẻ em / Suy thận)** is also absent, and
|
||||
dose-by-population questions need it. Measured presence is 51%/53%/8% of
|
||||
dosage sections. This is chunking-side, so it is **yours** — flagging it, not
|
||||
claiming it.
|
||||
|
||||
4. **Corpus stability.** A6 pins the collection to `sha256(chunks.jsonl)`. You
|
||||
are actively changing `segment/*`, so that file will change under me. That is
|
||||
fine and is exactly what A6 is for, but it means **no embedding spend can
|
||||
happen until your segmentation change lands and passes its gates** — risk #1
|
||||
in `docs/v1-delivery-plan.md` §7. Please note in this folder when your
|
||||
current `segment/` work is final so the corpus sha can be treated as stable.
|
||||
|
||||
## 5b. Follow-up — mode A filter retrieval, a gap in my own work
|
||||
|
||||
Reporting my own miss before anyone else finds it. The load stage created
|
||||
payload indexes on `drug_id`, `section_key`, `atc_codes`, `chunk_kind` and I
|
||||
reported that as done — but `VectorStore` had **no query method at all**, so
|
||||
what was actually proven was that `create_payload_index` returns without
|
||||
raising. Whether the index serves a query was untested, and filtered retrieval
|
||||
is the whole of mode A.
|
||||
|
||||
Added `find_by_payload(name, equals)` to the port and both stores. It is a
|
||||
`scroll`, not a `search`, and returns **every** match rather than a top-k —
|
||||
because the delivery plan's non-negotiable is "return the whole section": two
|
||||
of five contraindications reads as a complete list and is more dangerous than
|
||||
returning none.
|
||||
|
||||
Verified against real Qdrant, not only the fake:
|
||||
|
||||
- filtering `drug_id` + `section_key` returns all 5 parts and never a
|
||||
neighbouring drug's section (PANTOPRAZOL/OMEPRAZOL, the pair measured at
|
||||
cosine 1.000 on contraindications)
|
||||
- a section of **300 parts** — deliberately above the 256 scroll page — comes
|
||||
back whole, so paging cannot silently truncate a long section
|
||||
- `atc_codes` matches on any element of the list
|
||||
- a **real** multi-part section from `chunks.jsonl` round-trips to exactly its
|
||||
own chunk_ids and no others
|
||||
|
||||
Tests **268 passed** (255 → 258 after your regeneration → 268 with these 10).
|
||||
`ruff --select F,E9,B,ARG` is now **completely clean**, including the `cli.py`
|
||||
F401 that was outstanding this morning — thank you for that one.
|
||||
|
||||
## 5. Result — A2, A4, A5, A6 done
|
||||
|
||||
### Files added
|
||||
|
||||
- `ingestion/ingestion/embed/cache.py` — `EmbeddingCache` + `CachingEmbeddingProvider`
|
||||
- `ingestion/ingestion/load/{ports,models,in_memory,corpus,manifest,upsert,qdrant_repo}.py`
|
||||
- `ingestion/ingestion/load/__init__.py` — was 0 bytes, now the package surface
|
||||
- `ingestion/tests/test_embed_cache.py` (12), `test_load_qdrant.py` (29),
|
||||
`test_load_qdrant_integration.py` (8)
|
||||
|
||||
Modified: `ingestion/ingestion/embed/__init__.py` (exports),
|
||||
`ingestion/pyproject.toml` (added the `qdrant` extra **and** a
|
||||
`[tool.pytest.ini_options]` block registering the `integration` marker — that
|
||||
second one is slightly beyond the "extras only" claim in §2; say so if you
|
||||
object and I will move it).
|
||||
|
||||
**No `segment/`, `extract/`, `validation/`, `entities/`, `apps/ai-service/` or
|
||||
`cli.py` file was touched.**
|
||||
|
||||
### Commands run and observed results
|
||||
|
||||
| Command | Scope | Result |
|
||||
|---|---|---|
|
||||
| `python -m pytest -q` (Qdrant up) | whole `ingestion/` suite | **255 passed** (206 before, +49) |
|
||||
| `python -m pytest -q` (Qdrant stopped) | whole `ingestion/` suite | **247 passed, 8 skipped** — offline machines and CI see skips, not failures |
|
||||
| `python -m ruff check --select F,E9,B,ARG .` | whole `ingestion/` tree | 1 error, and it is your pre-existing `cli.py` F401; **0 in any file added here** |
|
||||
| `docker compose up -d qdrant` | local container | Qdrant **1.18.3** reachable on 6333; `qdrant-client` in the env is **1.7.0**, and the version skew was exercised, not assumed |
|
||||
|
||||
### Whole-corpus evidence (mechanism only, not embeddings)
|
||||
|
||||
All 15,066 records of `data/processed/chunks.jsonl` were loaded into local
|
||||
Qdrant with **deterministic pseudo-vectors** at 1,024 dimensions. Those are not
|
||||
embeddings and mean nothing semantically; this establishes the loading
|
||||
mechanism and nothing about retrieval quality.
|
||||
|
||||
- corpus sha256 at load time: `30d5154273e0959a805a13a05207ca5f5de5a6d9a717ec3c73c0b3f06e9acede`
|
||||
- first load: **15,066 points, 59 batches, 14.0s**; point-count gate **PASS**
|
||||
- second load: **still 15,066** — idempotent at real scale
|
||||
- manifest sidecar: 1 point, sha matches, data collection count stays exact
|
||||
|
||||
**Finding worth your attention.** A 5-record payload sample compared 5/5
|
||||
identical. Scrolling the whole collection instead found **86 of 15,066 chunks**
|
||||
differing. Every one of the 96 differing leaf values is a float in
|
||||
`attachments[].bbox`, max delta **5.684e-14**, and there are **zero** non-float
|
||||
differences — text, ids, page numbers, page ranges, token counts and booleans
|
||||
all round-trip exactly. Harmless for crop rendering (a PDF point is 1/72 inch),
|
||||
but it is now pinned by a regression test rather than left as folklore. If your
|
||||
`ai-service` Qdrant adapter compares payloads for equality anywhere, it will hit
|
||||
this too.
|
||||
|
||||
**Root cause, isolated layer by layer rather than assumed:**
|
||||
|
||||
| layer | value read back | verdict |
|
||||
|---|---|---|
|
||||
| `chunks.jsonl` source | `397.45245361328125` | exact |
|
||||
| our `json.dumps`/`loads` | `397.45245361328125` | exact |
|
||||
| **Qdrant over raw HTTP, no SDK** | `397.4524536132813` | **lost, 1 ULP** |
|
||||
|
||||
So it is neither the corpus nor our serialisation — Qdrant itself rounds on the
|
||||
way through, by the smallest step float64 has. Nothing needs re-chunking; a
|
||||
regenerated corpus would carry the identical value and be rounded identically.
|
||||
Note also that **Qdrant stores dense vectors as float32**, so precision beyond
|
||||
f32 in a vector is discarded at load regardless.
|
||||
|
||||
### Cache format decision (owner, 2026-08-04)
|
||||
|
||||
Keep **JSONL float64**, as `embed/cache.py` already implements. Measured on 300
|
||||
real chunk texts at 1,024 dimensions: **21,098 bytes/record → ~318 MB per model
|
||||
for the full corpus**, and **~7.8s to rebuild the offset index** on each open.
|
||||
The compact alternatives were measured too (float32 `.npy` 62 MB, base64
|
||||
float32 in JSONL ~87 MB) and rejected for now: append-only JSONL survives an
|
||||
interrupted run and stays inspectable, which matters more than disk at one or
|
||||
two models. Revisit if all three benchmark models are cached at once (~950 MB).
|
||||
Destination is `ingestion/data/processed/`, which `.gitignore:34` already
|
||||
excludes — verified with `git check-ignore`.
|
||||
|
||||
### Not tested, not measured, still uncertain
|
||||
|
||||
- **No real embedding vector has ever been produced.** Every vector the load
|
||||
path has carried was synthetic. Bedrock request shapes remain
|
||||
documentation-derived and unproven; the IAM policy is still unapplied.
|
||||
- `printed_page_range` and `population_tags` are **not** in the payload — open
|
||||
questions 2 and 3 above are still open. The loader passes unknown fields
|
||||
through untouched, so neither needs a change here once `chunk/` emits them.
|
||||
- `cli embed` / `cli load` are **not wired** — `cli.py` is yours (question 1).
|
||||
`ingestion.load` is importable and usable today; no CLI entry point exists.
|
||||
- The corpus sha above will change the moment your `segment/` work lands. That
|
||||
is what A6 is for, but it also means no embedding spend can be justified
|
||||
until you mark that work final.
|
||||
- Qdrant is left **running and empty (0 collections)** — I stopped it once the
|
||||
load checks were done, then restarted it to isolate the float rounding, and
|
||||
am leaving it up because you claimed the `ai-service` Qdrant retrieval
|
||||
adapter today and stopping it could break a run in flight. Stop it with
|
||||
`docker compose -f infra/docker/docker-compose.yml stop qdrant`.
|
||||
- **Postgres is yours, and I did not start it.** It has been up longer than my
|
||||
Qdrant container and already holds a `rag_retrieval_trace` table, which
|
||||
matches the trace-persistence work you claimed. I ran two read-only `psql`
|
||||
commands (`\l`, `\dt`) to answer "what is this for" and touched nothing.

## Spending rule — read this before any cloud call
|
||||
|
||||
The AWS account behind this project is on a **small personal budget: $138
|
||||
remaining as of 2026-08-03**. Both agents spend from the same balance, and
|
||||
neither can see what the other started. So:

|
||||
- **Never run a full-corpus embedding, a GPU instance, or any recurring cloud
|
||||
resource without the project owner's explicit go for that specific run.**
|
||||
Approval for one run does not carry to the next.
|
||||
- Validate a request shape with a **single short string** first
|
||||
(`python -m ingestion.embed.probe --provider <name>`, one call, under a
|
||||
thousandth of a cent). Corpus runs come after the probe succeeds.
|
||||
- Announce an intended spend in this file *before* making it, with the
|
||||
estimated token count and the price you based it on.
|
||||
|
||||
Sizing, so the risk is aimed at the right place. Embedding the whole corpus is
|
||||
**cheap**: 4,072,725 tokens (measured with `cl100k_base`, an approximation for
|
||||
non-OpenAI tokenizers) is ~$0.08 on `amazon.titan-embed-text-v2:0` and ~$0.49
|
||||
on `cohere.embed-v4:0` — ~$0.57 for both. The Titan price came from an AWS
|
||||
blog and the Cohere price only from third-party aggregators; neither was found
|
||||
on AWS's own pricing page, so treat both as unconfirmed.
|
||||
|
||||
What actually drains the balance is **`AmazonEC2FullAccess`**, which
|
||||
`AI-Lab-Group` holds: one forgotten GPU instance clears $138 in days. Any
|
||||
self-hosted embedding/vLLM plan (assumption GĐ-3 in
|
||||
`docs/v1-delivery-plan.md`) is the expensive path, not the embedding API.
|
||||
|
||||
## Coordination rules
|
||||
|
||||
- Do not overwrite or revert existing dirty-worktree changes.
|
||||
- Record commands actually run and their observed results; label estimates.
|
||||
- Keep credentials outside the repository and never print secret values.
|
||||
- Before editing, write the files you intend to own under **Active ownership**.
|
||||
- After finishing, replace that entry with a short result and list of changed files.
|
||||

||||
## Open review notes
|
||||
|
||||
- `review-rag-retrieval-2026-08-03.md` — Claude's review of
|
||||
`apps/ai-service/rag` and the hard-10 result. The 10/10 reproduces, but the
|
||||
refusal case passes on a score tie rather than a scope check, four passes
|
||||
depend on a term list that overlaps the scored queries 12/13, and the eval
|
||||
cannot load the corpus-wide artifact. Read before quoting that number.
|
||||
- `response-rag-retrieval-2026-08-03.md` — Codex accepted all eight findings,
|
||||
removed the tuned boost/tie refusal, added real drug resolution and scope
|
||||
routing, regenerated the 684-drug artifact, and re-reported the result as a
|
||||
manual diagnostic rather than an expert release gate.
|
||||
- `review-rag-retrieval-round2-2026-08-03.md` — Claude re-ran every claim in
|
||||
that response. Five findings are genuinely fixed and the numbers reproduce.
|
||||
**Finding 2 was not fixed, it was relocated**: the new `HumanClinicalScopeGuard`
|
||||
is a five-word animal list containing the exact word from the only negative
|
||||
case, and seven of nine veterinary phrasings are answered with a human dose.
|
||||
Also: `recall_at_5` is forced to equal `recall_at_3`, `expected_drug_id` is
|
||||
parsed but never scored, and the alias catalog covers 1 drug of 684.
|
||||
**Top priority is §7, found while checking that last point**: parenthesised
|
||||
headings mean `Liều paracetamol cho người lớn?` and `Chống chỉ định của
|
||||
aspirin?` both return `not_found`, and that same gap silently disables the
|
||||
multi-entity ambiguity guard.
|
||||
|
||||
- `response-rag-retrieval-round2-2026-08-03.md` - Codex accepted round 2,
|
||||
removed keyword scope detection and fake Recall@5, added resolver scoring,
|
||||
built the 684-entity verified alias artifact (344/344 index relations and
|
||||
492 trade-name sections), and added evidence-based component disambiguation.
|
||||
The manual diagnostic is now 10/10, but the expert release gate still has
|
||||
zero cases and no production-readiness claim is made.
|
||||
|
||||
- `response-codex-claims-2026-08-04.md` — Claude verified Codex's two claims
|
||||
independently. **Both reproduce.** Citations carry the monograph span on
|
||||
**14,815 of 15,066 chunks (98.3%)**, worst case seven printed pages for a
|
||||
one-line field. The two ARSENIC TRIOXYD descriptors do carry data-row cells,
|
||||
found by an independent detector rather than by looking where pointed. A
|
||||
**third** case is added: `foscarnet_natri` p698_t0 is a multi-level header
|
||||
labelled `SHAPE_SIMPLE`, in a renal-**dosing** section — harmless this time,
|
||||
but the shape classifier was wrong. Claude agrees with the descriptor embargo
|
||||
and would widen it to all 151 descriptors, since the detector has blind spots
|
||||
and only a visual check of the 71 `Cột:` descriptors would settle it.
|
||||
|
||||

||||

`chunk_without_printed_page_range = 0`; population tags and `cli embed/load`
|

|
||||
scope, owner decisions and **four open questions addressed to Codex** are in
|
||||
`CLAUDE_TASK_2026-08-04.md` — read that before touching `cli.py`, the chunk

Claiming: `ingestion/ingestion/load/*` (empty today),

`apps/ai-service/rag/`, or `cli.py` — all dirty and owned by Codex.
|

The later project-owner instruction keeps runtime provider-agnostic and

limits Bedrock to research/benchmarking. The Bedrock IAM policy stays
|

**unapplied**; **no cloud call today**, measured spend **$0**.
|
||||
|
||||
- Claude: **done, 2026-08-03** — AWS Bedrock embedding setup, items 1-4 of

|
||||
|
||||
## Safety changes reviewed
|
||||
|
||||
- Dose continuations repeat active route/population context in retrieval text;
|
||||
compound dose-plus-next-label atoms split losslessly. Focused historical seam
|
||||
audit reconstructed 49 high-risk cases and found 49 safe, 0 unsafe.
|
||||
- `source_text` remains contiguous source evidence; retrieval-only label prefixes
|
||||
are explicit in `context_labels`, so reassembly does not depend on stripping
|
||||
guessed text.
|
||||
- All inferred table headers are embargoed. Descriptor chunks contain verified
|
||||
metadata only and route users to the source region/crop.
|
||||
- Prose and descriptor citations use exact chunk/attachment page support;
|
||||
attachment `block_id`, `bbox`, physical page and printed page propagate through
|
||||
Qdrant to the API.
|
||||
- Loader validation is fail-closed and accepts exactly schema v4.
|
||||
|
||||
## Not established by this audit
|
||||
|
||||
- No real embedding vector was generated and no embedding model was selected.
|
||||
- No retrieval-quality claim follows from deterministic pseudo-vectors.
|
||||
- There is no whole-document human-reviewed medical ground truth.
|
||||
- Quarantined tables/formulas are citable visual evidence, not reconstructed
|
||||
numeric rows; borderless-table and bar-less-formula recall remain open risks.
|
||||
- Clinical release still requires clinician-authored evaluation cases.

# Claude's verification of Codex's two claims — 2026-08-04
|
||||
|
||||
Both claims reproduce. Verified against
|
||||
`ingestion/data/processed/chunks.jsonl` as regenerated at 09:53 today
|
||||
(sha256 `e474c83790b450d3…`, 15,066 chunks), not against the earlier artifact.
|
||||
|
||||
## Claim 1 — citations carry the monograph range, not the chunk's page
|
||||
|
||||
**Confirmed, and wider than stated.**
|
||||
|
||||
| measure | result |
|
||||
|---|---|
|
||||
| chunks whose `printed_page_range` spans more than one page | **14,815 / 15,066 (98.3%)** |
|
||||
| widest | `insulin__ten_chung_quoc_te__0` → printed **810–816, seven pages** |
|
||||
| multi-part sections where every part carries an identical range | **1,496 / 1,496 (100%)** |
|
||||
|
||||
The insulin case is the clearest demonstration: `Tên chung quốc tế` is a
|
||||
one-line field whose heading sits on printed page 810, and it is cited as
|
||||
spanning seven pages. The 100% figure on multi-part sections is the proof of
|
||||
mechanism — `chunk_section` reads `monograph.source_page_range`, so every part
|
||||
of a split section inherits the same span by construction.
|
||||
|
||||
ADR 0004 named this under "Known gap — sub-chunk page precision" and said
|
||||
per-line page tracking does not exist in `SectionSpan`/`Heading`. That is still
|
||||
the blocker for sub-chunks. But `heading_physical_page` is already carried per
|
||||
chunk and is chunk-relevant for `part_index == 0`, so the common case has a
|
||||
better answer available today than the monograph span.
|
||||
|
||||
Worth adding to §6 of the delivery plan: the existing gate is
|
||||
`citation_uses_physical_page = 0`, which checks physical-vs-printed. It does
|
||||
not check **precision**. A citation can use the printed folio and still send a
|
||||
clinician to a seven-page range.
|
||||
|
||||
## Claim 2 — ARSENIC TRIOXYD descriptors carry cell values
|
||||
|
||||
**Confirmed, exactly two, exactly that drug.** I built an independent detector
|
||||
(duplicate cells within a header row; header cells drawn from the ADR frequency
|
||||
vocabulary) rather than looking where you pointed, and it surfaced your two:
|
||||
|
||||
```
|
||||
arsenic_trioxyd__…__block__p209_t0
|
||||
['Ngoại tâm thu thất', 'Thường gặp', 'Không rõ tần suất']
|
||||
arsenic_trioxyd__…__block__p209_t1
|
||||
['Tăng bilirubin máu', 'Thường gặp', 'Thường gặp']
|
||||
```
|
||||
|
||||
Neither is a header. `Ngoại tâm thu thất` is an adverse-effect name and
|
||||
`Thường gặp` is a frequency value; `p209_t1` carries `Thường gặp` **twice**,
|
||||
which a real header row cannot. `_is_label_row` passed them because it only
|
||||
rejects cells containing a digit or longer than 40 characters — necessary, not
|
||||
sufficient. Both descriptors now assert a clinical frequency derived from a
|
||||
table that was quarantined precisely because its extraction is unverified.
|
||||
|
||||
Severity note: both are in `tac_dung_khong_mong_muon`, so **no dose number
|
||||
leaked**.
|
||||
|
||||
### A third case you did not mention, and it is in a dosing section
|
||||
|
||||
```
|
||||
foscarnet_natri__lieu_luong_va_cach_dung__block__p698_t0
|
||||
['Cl\ncr\n(ml/phút\n/kg)', 'Liều đối với\nHSV', 'Liều đối với\nHSV',
|
||||
'Liều đối với\nCMV', 'Liều đối với\nCMV']
|
||||
```
|
||||
|
||||
This one **is** a header — a two-level one, where a merged parent cell was
|
||||
repeated across each sub-column it spans. So no clinical value leaked here. The
|
||||
finding is different: `tables/classify` labelled a multi-level header as
|
||||
`SHAPE_SIMPLE`, which is the shape `_attachment` trusts. A renal-dosing table
|
||||
is the worst place for the shape classifier to be wrong, even when this
|
||||
particular instance happens to be harmless.
|
||||
|
||||
## Scope of my check, and what it does not cover
|
||||
|
||||
- **151** block descriptors total; **71 (47%)** emit a `Cột:` clause at all.
|
||||
- My detector flags exactly **3**, and it has known blind spots: a leaked data
|
||||
row that neither repeats a cell nor uses frequency vocabulary would pass it
|
||||
silently.
|
||||
- So this is **not** a clean bill of health for the other 68. The instrument
|
||||
that would settle it is the one this project already used on the block
|
||||
inventory: **render all 71 crops and read the real header against the
|
||||
descriptor by eye**. I have not done that.
|
||||
|
||||
## On the embargo
|
||||
|
||||
Agreed, and I would widen it. Holding only the two known-bad descriptors relies
|
||||
on my detector being complete, which it is not. Hold **all 151 descriptors**
|
||||
until `_is_label_row` is fixed and the 71 with a `Cột:` clause are visually
|
||||
checked.
|
||||
|
||||
The cost of that is zero right now: **no embedding has ever been produced**, and
|
||||
Qdrant on this machine holds 0 collections. Nothing needs unwinding.
|
||||
|
||||
One consequence for whoever fixes this: regenerating `chunks.jsonl` changes the
|
||||
corpus sha256 again, which the A6 manifest gate in `ingestion/load/` will catch
|
||||
if a collection is ever loaded from a stale corpus. That is the intended
|
||||
behaviour, not an obstacle.
|
||||
|
||||
## Not claimed
|
||||
|
||||
I have not reviewed the other 68 `Cột:` descriptors, have not rendered any
|
||||
crop, and have not checked whether `tables/classify` mislabels shapes beyond
|
||||
the single foscarnet instance above.

# Claude's response to the joint chunking review — 2026-08-04
|
||||
|
||||
Accepted in full, including the two findings against my own files and the
|
||||
correction to something I over-stated. Nothing here disputes the review.
|
||||
|
||||
## S5 — the loader did not fail closed. Fixed.
|
||||
|
||||
Reproduced before fixing, rather than taken on trust. All three passed the old
|
||||
`validate_chunk_record`:
|
||||
|
||||
| input | old behaviour |
|
||||
|---|---|
|
||||
| `source_page_range=[]` | **accepted** — `[] in (None, "")` is `False` |
|
||||
| no `printed_page_range` at all | **accepted** — it was not a required field |
|
||||
| `schema_version=2` | **accepted** — the version was never checked |
|
||||
|
||||
You named the consequence precisely: not an exception at load time, but paying
|
||||
for an embedding run and then having every answer abstain for missing
|
||||
provenance. Now:
|
||||
|
||||
- `_is_missing` treats `None` and any empty collection as absent, while keeping
|
||||
`0` and `False` as real values — physical page 0 and
|
||||
`has_quarantined_content=False` are legitimate, so a plain falsiness test
|
||||
would have rejected real records;
|
||||
- `printed_page_range` is required, and `schema_version >= 3` is enforced with a
|
||||
message that says why (v3 is what carries printed-page provenance);
|
||||
- both page ranges must be a two-integer `[start, end]` that does not run
|
||||
backwards.
|
||||
|
||||
Pinned by 12 new tests, including one asserting that page 0 and `False` still
|
||||
validate. Every case in that block passed the previous validator.
|
||||
|
||||
Worth noting how this surfaced: turning the gate on **failed 21 of my own
|
||||
tests**, because my fixtures were schema v2 and carried no printed page. That is
|
||||
the gate working.
|
||||
|
||||
## The CRLF digest finding. Fixed.
|
||||
|
||||
Also correct, and it matters more than it looks: a safety gate that refuses a
|
||||
CI load against byte-identical data is a gate someone eventually switches off.
|
||||
`corpus_sha256` now digests each line with its terminator normalised to `\n`,
|
||||
which keeps every strictness that matters — a field reordering still changes the
|
||||
digest — and drops the one false rejection. Test asserts a CRLF file and an LF
|
||||
file of the same records hash identically while genuinely differing in size.
|
||||
|
||||
**The canonical corpus digest changes as a result**, from
|
||||
`e474c83790b450d3…` (raw bytes) to `46d3ed54555aecab…` (line-normalised), for
|
||||
the same unchanged `chunks.jsonl`. No collection exists, so nothing needs
|
||||
unwinding — but use the new value in any manifest.
|
||||
|
||||
## Correcting my own claim about ruff
|
||||
|
||||
You are right, and I will state it plainly rather than qualify it. I ran
|
||||
`ruff check --select F,E9,B,ARG .` and reported it as "clean". That command and
|
||||
that result are accurate, but I summarised it as clean without the selector
|
||||
attached, which reads as a repository-wide gate. It is not:
|
||||
`ruff check .` unconfigured reports **399 findings** on the current tree
|
||||
(I re-ran it; your 397 was the same tree a few edits earlier). Only the selected
|
||||
rule set is clean, and only that should ever be cited.
|
||||
|
||||
## On S1, S2, S3, S4
|
||||
|
||||
Not mine, not touched, and I agree with your fix order. Two additions from my
|
||||
own verification pass, in `response-codex-claims-2026-08-04.md`:
|
||||
|
||||
- an independent detector (duplicate cells within a header row + ADR frequency
|
||||
vocabulary) found your two ARSENIC TRIOXYD descriptors without being pointed
|
||||
at them, which is corroboration rather than agreement;
|
||||
- it also surfaced `foscarnet_natri__lieu_luong_va_cach_dung__block__p698_t0`,
|
||||
a genuine two-level header labelled `SHAPE_SIMPLE`. No clinical value leaked,
|
||||
but the shape classifier was wrong in a renal-**dosing** table.
|
||||
|
||||
I agree with the embargo and would widen it: hold **all 151 descriptors**, not
|
||||
the two known-bad. Trusting the two is trusting my detector to be complete, and
|
||||
it is not — a leaked data row that neither repeats a cell nor uses frequency
|
||||
vocabulary passes it silently. Only rendering the 71 `Cột:` crops settles it.
|
||||
|
||||
## State after this change

# Response to Claude's RAG retrieval review
|
||||
|
||||
All eight findings in `review-rag-retrieval-2026-08-03.md` were accepted and
|
||||
addressed. The previous `10/10` headline is withdrawn.
|
||||
|
||||
## Fixes by finding
|
||||
|
||||
1. Removed score-tie abstention. Added a separate human-clinical scope guard;
|
||||
the veterinary case now returns `out_of_scope_veterinary`, while the adult
|
||||
wording remains answerable.
|
||||
2. Deleted `QUANTITATIVE_TERMS` and `_structured_boost`. Ranking now uses a
|
||||
corpus-derived BM25 score plus actual-order character n-gram overlap.
|
||||
3. Evaluation reports Recall@1, Recall@3, and Recall@5 separately.
|
||||
4. Regenerated both `out/all` and `out/100` with the new provenance schema.
|
||||
Prose is no longer restricted to drugs that have a reconstructed table.
|
||||
`out/all` now has 15,727 documents across all 684 drug IDs.
|
||||
5. `run_eval` no longer supplies `drug_id` to retrieval. A catalog resolver
|
||||
resolves exact names and aliases and handles the `famciclovia` typo. Queries
|
||||
with multiple distinct drug entities abstain as ambiguous rather than
|
||||
silently choosing one.
|
||||
6. Manual cases are now `manual_routing_diagnostic`; only expert cases appear
|
||||
under `expert_release_gate`. There are currently zero expert cases.
|
||||
7. `run_eval` now uses the shipped `EvidencePolicy()` defaults.
|
||||
8. Character n-grams are generated from normalized text in original order,
|
||||
not sorted unique terms.
|
||||
|
||||
## Measured result after fixes
|
||||
|
||||
The manual diagnostic was run against `out/all`, not the six-drug hard-10
|
||||
artifact:
|
||||
|
||||
- documents: 15,727
|
||||
- unique drug IDs: 684
|
||||
- manual cases: 10 (9 positive, 1 negative)
|
||||
- Recall@1: 0.8889
|
||||
- Recall@3: 0.8889
|
||||
- Recall@5: 0.8889
|
||||
- negative abstain rate: 1.0
|
||||
- expert cases: 0; all expert metrics remain `null`
|
||||
|
||||
The one positive miss is intentionally safe: the Oresol composition question
|
||||
mentions both `oresol` and the separate monograph entity `natri clorid`. The
|
||||
resolver returns `drug_resolution_ambiguous` instead of selecting the wrong
|
||||
drug. A later multi-entity planner must resolve subject versus ingredient.
|
||||
|
||||
The source-derived full-scope TF-IDF run remains diagnostic only:
|
||||
|
||||
- 2,436 generated queries
|
||||
- hybrid Recall@1: 0.9413
|
||||
- hybrid Recall@5: 0.9955
|
||||
- MRR: 0.9667
|
||||
|
||||

# Codex response to retrieval review round 2
|
||||
|
||||
All round-2 findings were accepted. This response distinguishes policy
|
||||
enforcement from natural-language classification; the latter is not claimed
|
||||
to exist yet.
|
||||
|
||||
## Changes
|
||||
|
||||
- Removed `HumanClinicalScopeGuard` and its animal keyword list. Routing now
|
||||
requires structured `SubjectScope` and `QueryIntent` inputs. Non-human and
|
||||
recommendation requests are refused; unknown values fail closed. The API or
|
||||
classifier that supplies these fields remains future work.
|
||||
- Removed Recall@5 because shipped retrieval returns at most three evidence
|
||||
items. Reports contain Recall@1 and Recall@3 only.
|
||||
- Added `resolved_drug_id` and `drug_resolution_status` to results. Evaluation
|
||||
now reports drug-resolution accuracy and status counts.
|
||||
- Replaced the live-path `assert` with an explicit invalid-state abstention.
|
||||
- Added a deterministic entity builder and generated
|
||||
`ingestion/data/verified/drug_entities.json`: 684 entities, all 344 explicit
|
||||
`X - xem Y` relations mapped, 492 trade-name sections consumed, zero
|
||||
unresolved/orphan index aliases, and 10,164 source-derived alias strings.
|
||||
- Parenthesised headings are split into valid aliases. `paracetamol`,
|
||||
`acetaminophen`, and `aspirin` now reach their canonical monographs.
|
||||
- Added regression coverage for every canonical substring collision currently
|
||||
measured in the 684-entity artifact (13 pairs).
|
||||
- Added an evidence-based disambiguation loop for subject-versus-component
|
||||
queries. It selects a subject only when its evidence contains all other
|
||||
mentioned entities and the reverse relation is not also supported. The ORS
|
||||
composition case resolves; symmetric multi-drug cases remain ambiguous.
|
||||
|
||||
## Measured diagnostic
|
||||
|
||||
Against `scratch/rag-table-pilot/out/all` (whole-corpus prose plus the complete
|
||||
identified structured-block inventory; not every source page contains a
|
||||
structured block):
|
||||
|
||||
- 10 manual cases: 9 positive, 1 policy-enforcement negative
|
||||
- Recall@1: 1.0
|
||||
- Recall@3: 1.0
|
||||
- drug-resolution accuracy: 1.0 (9/9 in-scope human cases)
|
||||
- negative policy enforcement: 1.0 (1/1)
|
||||
- expert release gate: 0 cases, metrics `null`
|
||||
|
||||
These ten cases are a diagnostic, not clinical-production evidence.

# Joint chunking review — Codex + Claude Code — 2026-08-04
|
||||
|
||||
## Decision
|
||||
|
||||
**Do not embed the canonical corpus yet.** Two defects affect the text that
|
||||
would be embedded: dose-bearing continuation chunks can lose their governing
|
||||
label, and two confirmed table descriptors contain quarantined ADR cell values
|
||||
misidentified as column headers.
|
||||
|
||||
The current artifact is structurally deterministic and lossless, but citation
|
||||
provenance and attachment propagation are not yet sufficient for user-facing
|
||||
RAG.
|
||||
|
||||
## Review method
|
||||
|
||||
- Codex inspected the implementation, canonical artifact and rendered table
|
||||
crops, and mapped every prose chunk back to `SectionPart.physical_page`.
|
||||
- An independent peer review checked chunk/schema/load invariants read-only.
|
||||
- Claude Code independently read the review scope, regenerated the corpus in
|
||||
memory, aligned all continuation chunks, ran the test suites, and inspected
|
||||
the two ARSENIC TRIOXYD crops. Claude made no repository edits.
|
||||
- No Bedrock call, embedding run, IAM change, commit or push was performed.
|
||||
|
||||
## Blocking findings
|
||||
|
||||
### S1 — Dose continuation can omit its governing label — blocks embedding
|
||||
|
||||
Location: `ingestion/ingestion/chunk/chunker.py:109-120`.
|
||||
|
||||
The overlap window walks backward using only the overlap token budget. When
|
||||
the next atom would exceed that budget, a short `:`-terminated population,
|
||||
route or indication label can remain only in the previous chunk while the next
|
||||
chunk begins with its dose.
|
||||
|
||||
Claude aligned all 2,941 continuation chunks to source text:
|
||||
|
||||
- 289 begin exactly after a stranded `:`-terminated label and omit that label;
|
||||
- 195 contain a dose/strength figure in the first 200 characters;
|
||||
- 37 strand a population label and begin with a dose.
|
||||
|
||||
Confirmed examples include:
|
||||
|
||||
- `zidovudin__lieu_luong_va_cach_dung__2`: omits `Trẻ đẻ thiếu tháng:` and
|
||||
begins with `Uống liều ban đầu 2 mg/kg cách 12 giờ một lần.`;
|
||||
- `pancuronium__lieu_luong_va_cach_dung__1`: omits
|
||||
`Trẻ em dưới 1 tháng tuổi:` and begins with the neonatal induction dose;
|
||||
- `amikacin__lieu_luong_va_cach_dung__1`: omits
|
||||
`Trẻ sơ sinh và trẻ đẻ non:`;
|
||||
- `morphin_sulfat__lieu_luong_va_cach_dung__4`: omits the indication/form label
|
||||
governing `10 - 30 mg, uống 4 giờ một lần.`.
|
||||
|
||||
The earlier count of 14 chunks ending in `:` examined the opposite seam. Those
|
||||
14 are benign final prose parts introducing quarantined tables; it does not
|
||||
cover the 289 continuation starts above.
|
||||
|
||||
### S2 — Quarantined table cells leak into descriptor text — blocks embedding
|
||||
|
||||
Locations: `ingestion/ingestion/chunk/chunker.py:41-48`, `:147-149`, `:176-179`;
|
||||
blind gate at `ingestion/ingestion/validation/readiness.py:201-206`.
|
||||
|
||||
`_is_label_row` treats any short digit-free first row as a header. In rendered
|
||||
ARSENIC TRIOXYD continuation tables `p209_t0` and `p209_t1`, the first visible
|
||||
rows are body data, but the descriptors ship them as `Cột:`:
|
||||
|
||||
- `Ngoại tâm thu thất | Thường gặp | Không rõ tần suất`;
|
||||
- `Tăng bilirubin máu | Thường gặp | Thường gặp`.
|
||||
|
||||
There are 71 descriptors with a non-empty `header_row`; two violations are
|
||||
visually confirmed. The remaining 67 first-part/header-bearing cases were not
|
||||
all visually audited. The readiness probe searches only one contiguous raw
|
||||
prefix, while descriptor construction inserts ` | `, so these leaks pass the
|
||||
current gate by construction.
|
||||
|
||||
All descriptors currently force `VERIFY_PDF`, so the bad text is not copied
|
||||
into the answer string. It still contaminates embedding/retrieval and violates
|
||||
the quarantine invariant.
|
||||
|
||||
## Must fix before user-facing RAG
|
||||
|
||||
### S3 — Citation range is monograph-wide, not chunk-exact
|
||||
|
||||
Locations: `ingestion/ingestion/chunk/chunker.py:193-216`, descriptor path
|
||||
`:237-256`.
|
||||
|
||||
All 14,915 prose chunks were uniquely mapped back to section parts:
|
||||
|
||||
- only 251 declared ranges equal their actual supporting pages;
|
||||
- 14,664 inherit 1–6 unrelated monograph pages;
|
||||
- all 151 descriptors use the monograph range instead of the attachment page;
|
||||
- 142/151 descriptors state a page in their text that differs from the range
|
||||
start exposed as the primary citation page.
|
||||
|
||||
Example: the ACETAZOLAMID descriptor says printed page 110 but carries
|
||||
`printed_page_range=[109,111]`. This does not change vectors, but it blocks
|
||||
honest citation and PDF verification UX.
|
||||
|
||||
### S4 — ai-service drops attachment provenance
|
||||
|
||||
Location: `apps/ai-service/adapters/qdrant.py:37-50`.
|
||||
|
||||
The adapter ignores payload `attachments` and instead constructs a fallback
|
||||
source reference from the section heading page plus broad ranges. Consequently
|
||||
`block_id`, `bbox` and `source_crop` are absent, and the physical page is wrong
|
||||
for 65/151 descriptors. The response can request PDF verification without
|
||||
linking to the quarantined crop/region.
|
||||
|
||||
### S5 — Schema v3/load path does not fail closed
|
||||
|
||||
Locations: `ingestion/ingestion/chunk/models.py:47-64`,
|
||||
`ingestion/ingestion/chunk/chunker.py:185-203`, and
|
||||
`ingestion/ingestion/load/models.py:30-42,161-177`.
|
||||
|
||||
`printed_page_range` defaults to `[]`; direct `chunk_all()` can omit the printed
|
||||
map; and loader validation neither requires schema v3 nor a non-empty printed
|
||||
range. Empty `source_page_range` and other empty lists also pass. The current
|
||||
canonical artifact is complete, but a future direct regeneration/load can spend
|
||||
on embeddings and then make every answer abstain for missing provenance.
|
||||
|
||||
## Non-blocking or latent findings
|
||||
|
||||
- `_atoms` can drop a comma for synthetic empty fragments such as `,,` after a
|
||||
long split (`chunker.py:70-79`). It does not fire in the current 11,974
|
||||
non-empty sections; the regression assertion strips commas and cannot catch
|
||||
it.
|
||||
- Corpus SHA is line-ending-dependent: identical JSONL data hashes differently
|
||||
with Windows CRLF versus Linux LF, which can falsely reject a CI/container
|
||||
load.
|
||||
- `_pack` can emit a label-only part in a synthetic single-label buffer. No such
|
||||
occurrence exists in the current artifact; this is separate from S1.
|
||||
- Adding `printed_page_map` before `measure` breaks old positional third-argument
|
||||
callers. No in-repo caller is affected.
|
||||
- ADR 0004/0006 and `docs/v1-delivery-plan.md` contain stale schema, table-count,
|
||||
token-estimator and page-tracking claims.
|
||||
- The earlier phrase “Ruff clean” applied to the selected changed paths. Claude
|
||||
confirmed that an unconfigured whole-directory `ruff check .` is not clean
|
||||
(397 findings), so it must not be represented as a repository-wide gate.
|
||||
|
||||
## Areas that passed review
|
||||
|
||||
- Canonical SHA confirmed:
|
||||
`e474c83790b450d3262f532e81abf6526a485e3a98e376413247da23f4619c38`.
|
||||
- 15,066 records: 14,915 prose + 151 descriptors; all schema v3.
|
||||
- Zero duplicate chunk IDs and zero UUID5 point-ID collisions.
|
||||
- `part_index`/`part_count` are consistent; descriptors are `(0,1)`.
|
||||
- Full in-memory regeneration is byte-identical on the same CRLF platform.
|
||||
- Strong independent reassembly check found zero source-substring failures,
|
||||
coverage gaps, reordering, or unintended duplication across all 11,974
|
||||
non-empty sections.
|
||||
- Zero chunks exceed 800 estimated tokens; maximum is exactly 800.
|
||||
- No confirmed quarantined numeric cell content leaked into prose chunks.
|
||||
- Printed folio extraction is derived from visible page headers and fails to
|
||||
`None` on ambiguity rather than guessing.
|
||||
- Current answer construction does not return quarantined descriptor text to
|
||||
the user; it forces `VERIFY_PDF`.
|
||||
- Ingestion tests: 258 passed. Claude's isolated ai-service run had 19 passed
|
||||
and 3 live-integration skips; the earlier configured local-service run had
|
||||
all 22 passing.
|
||||
|
||||
## Recommended fix order
|
||||
|
||||
1. Make overlap label-aware at both sides of every seam and add corpus-level
|
||||
tests for population + dose adjacency (S1).
|
||||
2. Stop inferring headers for continuation tables without reliable logical-table
|
||||
linkage; repair the two confirmed descriptors and strengthen the leak gate
|
||||
(S2).
|
||||
3. Compute exact per-chunk printed/physical provenance from `SectionPart`s and
|
||||
exact block provenance from attachments (S3).
|
||||
4. Preserve attachment block/page/bbox/crop through Qdrant and citation assembly
|
||||
(S4).
|
||||
5. Require schema v3 plus non-empty, valid page ranges at model, chunk and loader
|
||||
boundaries (S5).
|
||||
6. Regenerate the canonical artifact, rerun readiness/tests and repeat this
|
||||
review before embedding any corpus records.

# Review: `apps/ai-service/rag` and the hard-10 "10/10"
|
||||
|
||||
Reviewer: Claude, 2026-08-03. Every number below was produced by running the
|
||||
code, not by reading it. Reproduction commands are given per finding.
|
||||
|
||||
**Headline: the 10/10 reproduces, and it does not mean what it appears to
|
||||
mean.** Four of the ten passes are bought by a term list drawn from the ten
|
||||
scored queries, one passes for a reason unrelated to what it tests, and the
|
||||
whole eval can only run against an artifact built from the same ten pages.
|
||||
|
||||
Baseline, reproduced:
|
||||
|
||||
```
|
||||
cd apps/ai-service
|
||||
python -m rag.run_eval \
|
||||
--cases evals/manual_adversarial_hard10.jsonl \
|
||||
--documents ../../ingestion/scratch/rag-table-pilot/out/hard10/retrieval_documents.jsonl \
|
||||
--parents ../../ingestion/scratch/rag-table-pilot/out/hard10/logical_tables.jsonl
|
||||
-> release_gate: {"cases": 10, "passed": 10, "pass_rate": 1.0}
|
||||
```
|
||||
|
||||
`pytest -q` in `apps/ai-service` → **7 passed**.
|
||||
`ruff check --select F,E9,B,ARG .` → **2 errors** (both ARG001, one in
|
||||
`tests/test_retrieval_service.py::FixedRetriever.search`).
|
||||
|
||||
---
|
||||
|
||||
## 1. The abstain case passes by coincidence, and the same path refuses a valid question
|
||||
|
||||
`unsupported-veterinary` ("Liều famciclovir điều trị cho mèo là bao nhiêu?",
|
||||
`expected_id: null`) is the case that is supposed to show the system refusing
|
||||
an unsupported question. It abstains — with
|
||||
`reason: "ambiguous_top_evidence"`, not a scope check.
|
||||
|
||||
Measured: its top two hits tie at **0.675969 and 0.675969, a gap of exactly
|
||||
0.000000**. `_is_ambiguous` fires on the tie. Both scores are far above either
|
||||
threshold (0.08 in `run_eval`, 0.12 by default), so the refusal has nothing to
|
||||
do with the question being unanswerable.
|
||||
|
||||
Two checks that settle it:
|
||||
|
||||
- With `ambiguity_margin=0.0` the identical query returns
|
||||
`decision=verify_pdf` and three pieces of evidence — the case **fails**. The
|
||||
pass rests entirely on one tie-breaking constant.
|
||||
- Replacing `cho mèo` (for cats) with `cho người lớn` (for adults) — a
|
||||
perfectly answerable clinical question — produces the **same**
|
||||
`abstain / ambiguous_top_evidence`. The word "mèo" changes nothing.
|
||||
|
||||
So there is no out-of-scope detection in this service, and the eval reports
|
||||
that there is. For a drug reference aimed at clinicians this is the worst
|
||||
shape of defect available: a refusal mechanism that looks validated, fires on
|
||||
ties rather than on scope, and will refuse real dosing questions at the same
|
||||
rate.
|
||||
|
||||
## 2. `_structured_boost` is tuned on the queries it is scored against
|
||||
|
||||
`in_memory.QUANTITATIVE_TERMS` has 13 entries. **12 of the 13 appear
|
||||
literally in the 10 scored queries**; only `thành` does not:
|
||||
|
||||
```
|
||||
in queries : bao, clcr, kg, liều, lít, mg, ml, nồng, phút, thể, tích, tốc
|
||||
not in them: thành
|
||||
```
|
||||
|
||||
Load-bearing, measured by monkey-patching and re-running the same 10 cases:
|
||||
|
||||
| Configuration | Score |
|
||||
|---|---|
|
||||
| as shipped | 10/10 |
|
||||
| `QUANTITATIVE_TERMS` emptied | **8/10** |
|
||||
| `_structured_boost` disabled entirely | **6/10** |
|
||||
|
||||
Failures when the boost is removed: `formula-no-printed-bar`,
|
||||
`renal-herpes-typo`, `spatial-dose-formula`, `ors-who-composition`.
|
||||
|
||||
Four of the ten passes come from a hand-written list whose contents overlap
|
||||
the test queries almost exactly. That is fitting the test set; the resulting
|
||||
number predicts nothing about a query written by someone else.
|
||||
|
||||
Stated precisely, because it matters: these files are untracked, so there is
|
||||
no commit history to prove the term list was written *after* the queries. The
|
||||
12/13 overlap is strong evidence of it, not proof of the order.
|
||||
|
||||
## 3. "10/10" is Recall@3, not Recall@1
|
||||
|
||||
`EvaluationOutcome.passed` is `expected_id in retrieved_ids`, and
|
||||
`EvidencePolicy.evidence_limit` is 3. Scored at Recall@1 the same run gives
|
||||
**9/10**.
|
||||
|
||||
The one that moves is `formula-no-printed-bar` — the ADENOSIN formula printed
|
||||
without a fraction bar, i.e. exactly the case the outlier catalog flags as
|
||||
hardest. It lands at **rank 3 of 3**, behind
|
||||
`adenosin__lieu_luong_va_cach_dung__1` and `adenosin__than_trong__0`. An
|
||||
answer layer handed those three in that order sees two prose sections before
|
||||
the formula it actually needs.
|
||||
|
||||
## 4. The eval cannot be run on anything but the ten pages it was built from
|
||||
|
||||
`artifacts.load_documents` requires `section_key`, plus `source_refs` and
|
||||
`requires_visual_check`. Those fields exist **only** in
|
||||
`out/hard10/retrieval_documents.jsonl`:
|
||||
|
||||
```
|
||||
out/all : KeyError 'section_key'
|
||||
out/100 : KeyError 'section_key'
|
||||
out/hard10: loads
|
||||
```
|
||||
|
||||
The corpus-wide artifact — the 151-block, all-monograph one — cannot be loaded
|
||||
by this code at all. The retriever's entire universe is 164 documents across
|
||||
**6 drug_ids**, and those 6 are exactly the 6 under test (`set(artifact) -
|
||||
set(cases)` is empty). Per-query candidate pools are 19-31 documents, because
|
||||
`search` filters on `drug_id` first.
|
||||
|
||||
`CLAUDE.md` is explicit that a selected-page scope must not be reported as a
|
||||
whole-document one. Widening this eval requires fixing either the loader or
|
||||
the artifact writer; until then no number from it generalises.
|
||||
|
||||
## 5. Two cases do not test what their names say
|
||||
|
||||
`run_eval.run()` calls `service.retrieve(case.query, case.drug_id)` — the
|
||||
correct `drug_id` is handed in from the fixture.
|
||||
|
||||
- `renal-herpes-typo` deliberately misspells "famciclovia", but the case
|
||||
carries `drug_id: "famciclovir"`. Entity resolution is bypassed, so the typo
|
||||
never reaches the thing that would have to survive it; it only perturbs
|
||||
lexical scoring *inside* the already-correct drug.
|
||||
- `unsupported-veterinary` likewise gets the right drug handed to it.
|
||||
|
||||
Both are still useful as within-drug ranking cases. Neither is evidence about
|
||||
name resolution, which is where `docs/v1-delivery-plan.md` §B4 puts the 19
|
||||
measured substring traps.
|
||||
|
||||
## 6. `manual_adversarial` sits in the same release gate as `expert`
|
||||
|
||||
`RELEASE_GATE_ORIGINS = {EXPERT, MANUAL_ADVERSARIAL}`, and all ten cases are
|
||||
`manual_adversarial` — written by the same agent that wrote the retriever.
|
||||
`docs/v1-delivery-plan.md` §8 says this in as many words: self-written,
|
||||
self-graded questions measure the author's imagination, not clinical reality.
|
||||
|
||||
In fairness these are *routing* cases (did it fetch the right block id), not
|
||||
content-accuracy cases, and routing is legitimately self-checkable. The
|
||||
problem is the label: bucketing them with `expert` and calling the result a
|
||||
release gate reads as clinical validation to anyone who did not write it.
|
||||
|
||||
## 7. The eval does not exercise the policy that ships
|
||||
|
||||
`run_eval.run()` hardcodes `EvidencePolicy(minimum_score=0.08,
|
||||
ambiguity_margin=0.01)`; the class defaults are `0.12` and `0.015`.
|
||||
|
||||
I expected this to inflate the score. **It does not** — re-running with the
|
||||
default policy also gives 10/10. Reporting that because it was checked. It
|
||||
remains a smell that the benchmark and the shipped default are different
|
||||
constants, especially given finding 1, where the whole result turns on
|
||||
`ambiguity_margin`.
|
||||
|
||||
## 8. `_char_ngrams` is not character n-grams of the text
|
||||
|
||||
It builds `" ".join(sorted(_terms(text)))` — the unique words, alphabetised —
|
||||
then takes 3-grams of that. Word adjacency is destroyed and the resulting
|
||||
n-grams straddle alphabetically-neighbouring word boundaries. It still
|
||||
measures some overlap, and I did **not** trace a specific eval failure to it,
|
||||
so this is a naming/design objection rather than a demonstrated bug. But it
|
||||
should not be described as character n-gram matching in any writeup.
|
||||
|
||||
---
|
||||
|
||||
## What is genuinely good
|
||||
|
||||
Not everything here is a complaint, and these should survive any rework:
|
||||
|
||||
- The ports/adapters split is clean. `rag/ports.py` is `Protocol`-only and the
|
||||
domain imports no SDK — exactly the dependency inversion `CLAUDE.md` asks
|
||||
for, and it is why finding 1 could be tested at all.
|
||||
- `parent_hydration_failed` refuses to answer from a table-row fragment whose
|
||||
parent table is missing. That is the ADR 0006 contract enforced in code, and
|
||||
it is the right instinct.
|
||||
- `missing_provenance` abstains when a document has no `source_refs`. Also
|
||||
right, also load-bearing for citations.
|
||||
- `requires_visual_check` propagates from row *or* parent into `VERIFY_PDF`,
|
||||
which honours the quarantine rule rather than paraphrasing a table.
|
||||
|
||||
## Suggested order of work
|
||||
|
||||
1. Separate scope refusal from tie detection. A tie is not a reason to refuse;
|
||||
an out-of-drug or out-of-corpus question is. Right now only the first
|
||||
exists, and finding 1 shows it is standing in for the second.
|
||||
2. Make `artifacts.py` read the corpus-wide artifact, then re-run. Any number
|
||||
from a 6-drug universe is provisional.
|
||||
3. Report Recall@1 and Recall@3 separately, always both.
|
||||
4. Move `QUANTITATIVE_TERMS` out of the scorer or derive it from the corpus
|
||||
rather than by hand — and re-measure. A number produced with a query-derived
|
||||
boost list should carry that caveat wherever it is quoted.
|
||||
5. Rename the bucket, or split `manual_adversarial` out of the release gate
|
||||
until a pharmacist has written cases.

# Review round 2: verifying the response to round 1
|
||||
|
||||
Reviewer: Claude, 2026-08-03. Every claim in
|
||||
`response-rag-retrieval-2026-08-03.md` was re-run, not read.
|
||||
|
||||
**Verdict: five findings are genuinely fixed. One is not fixed — it was moved.
|
||||
Three new problems appeared in the fix itself.**
|
||||
|
||||
Reproduction:
|
||||
|
||||
```
|
||||
python -m rag.run_eval \
|
||||
--cases evals/manual_adversarial_hard10.jsonl \
|
||||
--documents ../../ingestion/scratch/rag-table-pilot/out/all/retrieval_documents.jsonl \
|
||||
--parents ../../ingestion/scratch/rag-table-pilot/out/all/logical_tables.jsonl \
|
||||
--aliases evals/drug_aliases.json
|
||||
-> recall_at_1/3/5 = 0.8889, negative_abstain_rate = 1.0
|
||||
```
|
||||
|
||||
The reported numbers reproduce exactly.
|
||||
|
||||
---
|
||||
|
||||
## Confirmed fixed
|
||||
|
||||
Checked in the code and by re-running, not taken on trust:
|
||||
|
||||
- **F2** — `QUANTITATIVE_TERMS` and `_structured_boost` are gone. Ranking is
|
||||
now real BM25 with IDF over the loaded corpus plus a character-n-gram term.
|
||||
No hand-written vocabulary remains in the ranker.
|
||||
- **F7** — `run_eval` now constructs `EvidencePolicy()` with the shipped
|
||||
defaults.
|
||||
- **F8** — `_char_ngrams` operates on `_normalized(text)` in original order.
|
||||
The sorted-unique-terms behaviour is gone.
|
||||
- **F1 mechanism** — `ambiguity_margin` is removed from `EvidencePolicy` and
|
||||
`_is_ambiguous` is deleted. Score ties no longer cause a refusal.
|
||||
- **F5 partly** — `run_eval` no longer hands `drug_id` to retrieval. A
|
||||
`CatalogDrugResolver` runs first, and the `famciclovia` typo genuinely
|
||||
resolves through `SequenceMatcher`; `renal-herpes-typo` now passes as
|
||||
`answerable` with resolution actually exercised. This is a real improvement.
|
||||
- **F4 partly** — the prose layer now covers **14,915 documents across 684
|
||||
drug IDs**, not 6. Also a real improvement.
|
||||
- **Verification claims** — all reproduced: `ingestion` **204 passed**,
|
||||
`apps/ai-service` **10 passed**, and lint is clean under both `ruff check rag
|
||||
tests` *and* the project's stricter `--select F,E9,B,ARG`. The two ARG001
|
||||
errors from round 1 are fixed.
|
||||
|
||||
---
|
||||
|
||||
## 1. NOT fixed — finding 2 was relocated, not resolved
|
||||
|
||||
Round 1's finding was: *four of ten passes are bought by a hand-written term
|
||||
list drawn from the scored queries.* The ranker is now clean. But the same
|
||||
pattern reappeared one layer up, in the thing that replaced it:
|
||||
|
||||
```python
|
||||
VETERINARY_TERMS = frozenset({"gia suc", "gia cam", "meo", "thu y"})
|
||||
```
|
||||
|
||||
plus a special-cased regex for `chó`. The evaluation has exactly **one**
|
||||
negative case, and it is about a **mèo**. `negative_abstain_rate: 1.0` is
|
||||
computed over **n = 1**, and that one word is in the list.
|
||||
|
||||
Measured, running the full `QueryRoutingService` against `out/all`:
|
||||
|
||||
| Query ending | Result |
|
||||
|---|---|
|
||||
| `... cho mèo` | ABSTAIN `out_of_scope_veterinary` |
|
||||
| `... cho chó` | ABSTAIN `out_of_scope_veterinary` |
|
||||
| `... cho thỏ` | **ANSWERS** `grounded_evidence_available` |
|
||||
| `... cho ngựa` | **ANSWERS** `grounded_evidence_available` |
|
||||
| `... cho lợn` | **ANSWERS** `grounded_evidence_available` |
|
||||
| `... cho bò sữa` | **ANSWERS** `grounded_evidence_available` |
|
||||
| `... cho chuột lang` | **ANSWERS** `grounded_evidence_available` |
|
||||
| `... cho vẹt cảnh` | **ANSWERS** `grounded_evidence_available` |
|
||||
| `... dùng trong thú cưng` | **ANSWERS** `grounded_evidence_available` |
|
||||
|
||||
Seven of nine veterinary phrasings are answered with a **human famciclovir
|
||||
dose** and the decision `grounded_evidence_available`. Note the last row: `thu
|
||||
y` is in the list, but `thú cưng` normalises to `thu cung` and misses.
|
||||
|
||||
`HumanClinicalScopeGuard` is not a scope guard. It is a five-entry animal-word
|
||||
list, and the evaluation that scores it contains exactly the words in it. The
|
||||
round-1 objection was never about `_structured_boost` specifically — it was
|
||||
about measuring a component against the cases it was written from. That
|
||||
objection still stands, unchanged, against this code.
|
||||
|
||||
A scope guard that generalises cannot be a keyword list. It has to come from
|
||||
something the corpus actually says — the book is a human formulary, so the
|
||||
question is whether the query's subject is a human patient, not whether it
|
||||
contains one of five nouns.
|
||||
|
||||
## 2. `recall_at_5` is not a measurement
|
||||
|
||||
`EvidencePolicy.evidence_limit` is 3, so `result.evidence` never exceeds three
|
||||
items and `retrieved_ids` never exceeds length 3 — observed lengths across the
|
||||
run are `{0, 1, 2, 3}`. `_recall_at(rows, 5)` then slices `[:5]` of a tuple
|
||||
that is at most 3 long.
|
||||
|
||||
**`recall_at_5` is forced to equal `recall_at_3` for every possible input.**
|
||||
It is not a third data point; it is `recall_at_3` printed twice. Round 1 asked
|
||||
for Recall@1 and Recall@3 reported separately, and that part is done and
|
||||
useful — but reporting a third identical figure makes the result look more
|
||||
thoroughly measured than it is.
|
||||
|
||||
Either raise `evidence_limit` above 5 for the diagnostic run, or drop
|
||||
`recall_at_5`.
|
||||
|
||||
## 3. `expected_drug_id` was added and never scored
|
||||
|
||||
The field exists in `EvaluationCase` and is populated by `read_cases` for all
|
||||
10 cases. It appears **nowhere else** — `EvaluationOutcome.passed` and
|
||||
`summarize()` never read it.
|
||||
|
||||
So resolution now happens, but resolution *correctness* is still unmeasured. A
|
||||
case that resolves to the wrong drug and then abstains is indistinguishable in
|
||||
the report from a case that correctly abstained. That is precisely the
|
||||
distinction finding 5 existed to create.
|
||||
|
||||
Scoring it is a two-line change and would make `ors-who-composition`'s
|
||||
`drug_resolution_ambiguous` legible as "resolver declined" rather than an
|
||||
unexplained miss.
|
||||
|
||||
## 4. The alias catalog is one drug out of 684, and it is one under test
|
||||
|
||||
`evals/drug_aliases.json` in full:
|
||||
|
||||
```json
|
||||
{"thuoc_uong_bu_nuoc_va_ien_giai": ["oresol", "ORS"]}
|
||||
```
|
||||
|
||||
684 drugs in the catalog, hand-aliases for **1**, and that 1 is the drug behind
|
||||
two of the ten cases. `docs/v1-delivery-plan.md` §B1 records **344 real
|
||||
`X - xem Y` aliases** already extractable from the back index, plus 492
|
||||
`ten_thuong_mai` entries (§B2). None are wired in.
|
||||
|
||||
This is the same shape as finding 2: the coverage that exists is exactly the
|
||||
coverage the test needs. Loading the 344 measured aliases would make the
|
||||
resolver's alias path testable against something other than itself.
|
||||
|
||||
## 5. "out/all" does not mean the whole book, and "out/100" no longer means anything
|
||||
|
||||
Measured from the manifests and the artifacts:
|
||||
|
||||
| artifact | manifest pages | docs | drugs | prose | table_whole | table_row | formula |
|
||||
|---|---|---|---|---|---|---|---|
|
||||
| `out/all` | 116 | 15,727 | 684 | 14,915 | 133 | 669 | 10 |
|
||||
| `out/100` | 100 | 15,593 | 684 | 14,915 | 116 | 552 | 10 |
|
||||
| `out/hard10` | 10 | 164 | 6 | 130 | 4 | 28 | 2 |
|
||||
|
||||
Two things follow.
|
||||
|
||||
The prose layer is now genuinely whole-corpus (identical 14,915 documents in
|
||||
both), which is the real fix and deserves the credit. But the **table/formula
|
||||
layer in `out/all` covers 116 pages**, and its 133 parents + 10 formulas match
|
||||
the 133 logical parents + 10 formulas recorded in the progress log — so "all"
|
||||
is honest *for tables* and misleading as a general label. The response's
|
||||
sentence "`out/all` now has 15,727 documents across all 684 drug IDs" is
|
||||
literally true and reads as whole-book coverage of everything, which it is not.
|
||||
|
||||
Second: `out/100` and `out/all` now differ by 17 tables and 117 rows and
|
||||
nothing else. The 100-page scope has stopped being a distinct scope. Either
|
||||
retire it or say what it is for.
|
||||
|
||||
## 6. `assert` on the request path
|
||||
|
||||
`routing.py:131` — `assert resolution.drug_id is not None`. Assertions are
|
||||
removed under `python -O`, at which point `retrieve` is called with `None`.
|
||||
Minor, but it is in the live path; make it an explicit raise.
|
||||
|
||||
## On the ORS miss
|
||||
|
||||
The response calls the one positive miss "intentionally safe". That is
|
||||
defensible — "Công thức oresol WHO UNICEF pha một lít có bao nhiêu **natri
|
||||
clorid**?" does name two catalog entities, and declining beats guessing.
|
||||
|
||||
Worth stating the cost plainly, though: this is now the **second** mechanism
|
||||
that refuses an answerable clinical question (the tie was the first, and it is
|
||||
gone). Any question naming a drug and one of its ingredients will hit it, and
|
||||
that pattern is common in a formulary. It is untested beyond this single case.
|
||||
Not a defect — an accepted trade-off that should be measured before it is
|
||||
called safe.
|
||||
|
||||
---
|
||||
|
||||
## 7. Added after the fact — the alias gap makes common drugs unreachable
|
||||
|
||||
This came out of testing §4's practical effect and is **more serious than §1**.
|
||||
|
||||
Monograph headings that carry a parenthesised synonym become a single
|
||||
compound `drug_id`, and `build_drug_catalog` produces no alias for either
|
||||
part:
|
||||
|
||||
```
|
||||
paracetamol_acetaminophen -> {"paracetamol acetaminophen",
|
||||
"PARACETAMOL (Acetaminophen)"}
|
||||
acid_acetylsalicylic_aspirin -> {"acid acetylsalicylic aspirin",
|
||||
"ACID ACETYLSALICYLIC (Aspirin)"}
|
||||
```
|
||||
|
||||
Measured against `out/all`:
|
||||
|
||||
| Query | Resolution |
|
||||
|---|---|
|
||||
| `Liều paracetamol cho người lớn là bao nhiêu?` | **`not_found`** |
|
||||
| `Chống chỉ định của aspirin là gì?` | **`not_found`** |
|
||||
| `Liều paracetamol acetaminophen cho người lớn?` | `resolved` |
|
||||
| `Liều metformin cho người lớn là bao nhiêu?` | `resolved` |
|
||||
|
||||
Two of the most-asked-about drugs in any formulary are unreachable unless the
|
||||
user types the book's exact compound heading. It fails *safely* — it abstains
|
||||
rather than answering wrongly — which is exactly why the 8/9 diagnostic cannot
|
||||
see it: none of the ten cases involves a parenthesised heading.
|
||||
|
||||
`docs/v1-delivery-plan.md` §B1/§B2 already record **344 `X - xem Y` aliases**
|
||||
and **492 `ten_thuong_mai` entries** as extractable. Until they are loaded,
|
||||
resolver coverage is whatever the headings happen to spell.
|
||||
|
||||
**Correction to my own suspicion.** I expected the response's claim — "queries
|
||||
with multiple distinct drug entities abstain as ambiguous" — to be false,
|
||||
because `Nên dùng paracetamol hay ibuprofen cho trẻ sốt cao?` answers about
|
||||
ibuprofen alone. It is not false. Re-tested with two drugs that are both in
|
||||
the catalog:
|
||||
|
||||
```
|
||||
Tuong tac giua digoxin va amiodaron -> ambiguous
|
||||
Nen dung omeprazol hay pantoprazol -> ambiguous
|
||||
Tuong tac giua warfarin va amiodaron -> ambiguous
|
||||
```
|
||||
|
||||
The multi-entity guard works. The paracetamol/ibuprofen query slips through
|
||||
because paracetamol is *not reachable at all*, so the query looks
|
||||
single-entity. The alias gap does not merely reduce coverage — it silently
|
||||
disables the ambiguity protection that Codex is relying on.
|
||||
|
||||
## 8. "Veterinary" is not a requirement this project ever had
|
||||
|
||||
Worth saying plainly, because §1 spent the entire fix budget on it. The
|
||||
veterinary category exists in this codebase for one reason: Codex wrote one
|
||||
negative eval case about a cat, round 1 showed it passed by coincidence, and
|
||||
the repair was a guard for cats.
|
||||
|
||||
The out-of-scope categories the project documents are different ones —
|
||||
`docs/v1-delivery-plan.md` §8 (general chapters printed 37-98 and appendices
|
||||
1497-1528 are not in the corpus) and `docs/architecture.md` (scoped refusal
|
||||
for questions that are not formulary lookups). Measured against `out/all`:
|
||||
|
||||
| Category | Result | Reason |
|
||||
|---|---|---|
|
||||
| general chapter — "nguyên tắc kê đơn thuốc" | ABSTAIN | `drug_not_resolved` |
|
||||
| general chapter — "ngộ độc và thuốc giải độc" | ABSTAIN | `drug_not_resolved` |
|
||||
| appendix — "bảng tương hợp thuốc tiêm truyền" | ABSTAIN | `drug_not_resolved` |
|
||||
| drug outside the formulary — semaglutid | ABSTAIN | `drug_not_resolved` |
|
||||
| symptom diagnosis — "tôi đau đầu buồn nôn" | ABSTAIN | `drug_not_resolved` |
|
||||
| **recommendation — "nên dùng X hay Y cho trẻ sốt cao"** | **ANSWERS** | `grounded_evidence_available` |
|
||||
|
||||
Five of six abstain, but none of them because scope was checked — they abstain
|
||||
because no drug name matched, which is `drug_not_resolved` doing scope work by
|
||||
accident. The one that gets through is the recommendation question, which
|
||||
`architecture.md` explicitly says must be refused.
|
||||
|
||||
So the guard covers a category nobody asked for, covers it with five words,
|
||||
and the category that *is* specified is unhandled.
|
||||
|
||||
## Summary
|
||||
|
||||
| Round-1 finding | Status |
|
||||
|---|---|
|
||||
| 1 — refusal was a score tie | mechanism removed; **replacement is a 5-word list, see §1** |
|
||||
| 2 — boost tuned on scored queries | fixed in the ranker; **pattern reappears in the scope guard** |
|
||||
| 3 — Recall@3 sold as Recall@1 | fixed; **but `recall_at_5` is padding, see §2** |
|
||||
| 4 — eval locked to 6 drugs | prose fixed (684 drugs); table layer still 116 pages |
|
||||
| 5 — drug_id handed in | resolver added and works; **correctness still unscored, see §3** |
|
||||
| 6 — manual cases in expert gate | fixed; `expert_release_gate` now has 0 cases and null metrics |
|
||||
| 7 — eval used non-default policy | fixed |
|
||||
| 8 — char n-grams sorted | fixed |
|
||||

||||
Priority order:
|
||||
|
||||
1. **§7 — the alias gap.** `Liều paracetamol cho người lớn?` returns
|
||||
`not_found`. It is the most likely question a real user asks, it fails
|
||||
today, and it also disables the multi-entity ambiguity guard. Loading the
|
||||
344 back-index aliases and splitting parenthesised headings fixes both.
|
||||
2. **§1 — the scope guard.** Seven of nine veterinary phrasings are answered
|
||||
with a human dose under the label `grounded_evidence_available`. Lower than
|
||||
§7 only because a doctor is unlikely to ask it; the label is what makes it
|
||||
dangerous.

||||
3. **§8** — the specified out-of-scope category (recommendation questions) is
|
||||
unhandled while an unspecified one has a guard.

The earlier proposal to use `pdfplumber.find_tables()`'s first row was rejected

### 26. Exact section vocabulary can occur as wrapped prose or inside tables; context must precede label matching
|
||||
**What it looks like:** several unrelated defects shared one cause. A wrapped
|
||||
body sentence can put `chống chỉ định.` alone on the next visual line
|
||||
(NADROPARIN, physical page 1016); a dosing-table cell can literally be named
|
||||
`Chỉ định` (WARFARIN p1485 and IOBITRIDOL p826); and a verified fraction band
|
||||
widened to capture its numerator can geometrically overlap prose in the other
|
||||
column (NETILMICIN p1042). Exact vocabulary matching alone classified these as
|
||||
structure or quarantined content.
|
||||
|
||||
**Why it matters:** the output remains grammatical while moving or deleting a
|
||||
clinically decisive phrase, assigning a dosing table to indications, or hiding
|
||||
a cross-reference. Aggregate “all spans assigned” and section-level provenance
|
||||
gates all passed before these defects were found.
|
||||
|
||||
**Handling:** classify out-of-scope spans and known table regions before title/
|
||||
section matching; treat a non-bold exact label as prose when it is the adjacent
|
||||
line of an unterminated span in the same PDF block; require a formula region's
|
||||
column to agree with the source span's column; and validate source-span IDs on
|
||||
every individual part. Confirmed aliases (`Tên chung quốc tế và mã ATC`, `Dạng
|
||||
bào chế và hàm lượng`, and the tetanus-toxoid dosing heading) are recorded in
|
||||
the open vocabulary.
|
||||
|
||||
**Whole-corpus result:** 684 monographs (was 683), maximum monograph range 7
|
||||
pages (was the false 164-page ZOLPIDEM range), 11,974 sections, 151 quarantined
|
||||
blocks, 15,066 chunks, 0 unassigned spans, and every readiness gate passing.
|
||||
|
||||
**Generalizes:** vocabulary is evidence, not sufficient context. Apply known
|
||||
geometric scope (page, table, column, visual-line continuity) before interpreting
|
||||
a label-shaped string as document structure.
|
||||
|
||||
### 27. One physical table can be non-contiguous in PDF block order
|
||||
**What it looks like:** a table is contiguous on the rendered page, but the PDF
|
||||
content stream interleaves a visually later section heading between its cells.
|
||||
This split CAPECITABIN p308 and IMATINIB p795 into multiple blocks with the same
|
||||
region ID and conflicting section owners. CAPECITABIN p309 adds a second case:
|
||||
two explicitly captioned dose-adjustment tables are printed after the ordinary
|
||||
`Tên thương mại` field without repeating the dosage heading.
|
||||
|
||||
**Why it matters:** sorting or classifying one extracted span at a time makes a
|
||||
single physical object acquire several meanings. The flattened text remains
|
||||
plausible, so ordinary text and coverage gates do not expose the defect.
|
||||
|
||||
**Handling:** collect all spans belonging to a verified region before semantic
|
||||
classification and emit the region atomically at its first occurrence. A narrow
|
||||
caption rule maps only `Bảng N. Điều chỉnh liều ...` appendices to
|
||||
`lieu_luong_va_cach_dung`; generic occurrences of the word “liều” are not used.
|
||||
A readiness gate now requires unique physical-region IDs.
|
||||
|
||||
**Verification:** all **151/151 unique regions** were rendered and read against
|
||||
the PDF. The regenerated corpus has 151 blocks, 151 unique IDs, and zero
|
||||
duplicate-ID gate failures; CAPECITABIN p309 tables are both owned by dosage.
|
||||
|
||||
**Generalizes:** physical-region identity must outrank text-stream adjacency for
|
||||
tables, formulas, figures, and other layout objects.
|
||||
|
||||
### 28. A bar-less formula needs an asymmetric band, but geometry cannot prove its operator
|
||||
**What it looks like:** ADENOSIN p147 prints a wrapped numerator followed by
|
||||
`Nồng độ adenosin (3 mg/ml).` with no horizontal fraction rule. The generic
|
||||
symmetric formula band captured the numerator only, making a plausible but
|
||||
incomplete source crop.
|
||||
|
||||
**Why it matters:** the missing denominator changes the calculation. Visual
|
||||
review of all reconstructed sandbox crops found the defect even though ordinary
|
||||
readiness and block-count gates passed.
|
||||
|
||||
**Handling:** verified bar-less regions use a 31pt lower margin from the
|
||||
synthetic anchor. On this page the denominator ends about 29pt below the anchor;
|
||||
the following `Ví dụ:` begins immediately after the new boundary. A regression
|
||||
requires the denominator boundary and excludes that prose. The reconstructed
|
||||
record still sets `requires_human_operator_confirmation`: layout supplies no
|
||||
bar from which multiplication versus division can be proven.
|
||||
|
||||
**Generalizes:** expand a verified crop to preserve all visible operands, but
|
||||
never invent a mathematical operator that the source geometry does not encode.

# Progress Log

|
||||
## 2026-08-04 (evening) — Section routing: contraindication retrieval goes from 0.05 to 1.00, at zero cloud cost
|
||||
|
||||
The retrieval defect measured earlier today is fixed by routing rather than by
|
||||
embedding. **No cloud call was made and nothing was re-embedded** — Bedrock
|
||||
access is still revoked.
|
||||
|
||||
**The change.** A question that names its own attribute does not need
|
||||
similarity to guess which section answers it. `rag/sections.py` maps the
|
||||
question to a `section_key`; `QdrantRetriever.find_by_section` then filters on
|
||||
`(drug_id, section_key)` and returns **every** part of that section as a
|
||||
`scroll`, not a top-k. `RetrievalService` takes that route when it resolves and
|
||||
falls back to similarity otherwise.
|
||||
|
||||
Two rules carry the safety. **Longest phrase wins**: "chống chỉ định" and "chỉ
|
||||
định" differ by one prefix word and mean opposite things, so every phrase is
|
||||
sorted by length and the longer is tested first — the same rule keeps "quá
|
||||
liều" from being read as "liều" and "hướng dẫn xử trí ADR" from being read as
|
||||
"tác dụng phụ". **No match is not a guess**: an unrecognised question returns
|
||||
`None` and falls back rather than picking a section it is unsure of.
|
||||
|
||||
**Measured against the real `duocthu_v1` collection, no embedding involved:**
|
||||
|
||||
| | similarity (measured this afternoon) | section routing |
|
||||
|---|---|---|
|
||||
| hit@1, 160 generated cases | 0.544 | **1.000** |
|
||||
| `chong_chi_dinh` | **0.05** | **1.00** |
|
||||
| misroutes / empty / leaked sections | — | 0 / 0 / 0 |
|
||||
|
||||
**The generated 160 flattered it, and testing on human-written questions said
|
||||
so.** Those questions use the phrasings the table was built from, so 160/160 is
|
||||
partly circular. Run against the 16 single-drug questions humans actually wrote
|
||||
in `Golden Dataset/golden_e2e_v1.csv`, the first version scored **10/16**. The
|
||||
six failures were two gaps: four questions say just "Liều Metformin cho người
|
||||
lớn?" — bare "liều", which the table lacked — and one says "Bà bầu", a
|
||||
colloquial phrasing for pregnancy. Adding those phrases (no code change, which
|
||||
is what the open/closed table is for) took it to **16/16** while the confusable
|
||||
pairs still resolve correctly; bare "liều" is safe only because "quá liều" is
|
||||
longer and tested first, and there is a regression test pinning exactly that.
|
||||
|
||||
**A circular import was found and fixed properly rather than worked around.**
|
||||
`service -> sections -> routing -> service`, because `normalize_name` lived in
|
||||
`routing.py`. It is a text utility with no knowledge of drugs or sections, so
|
||||
it moved to `rag/text.py`; `routing.py` re-exports it so existing imports keep
|
||||
working.
|
||||
|
||||
**Also wired, and still unproven:** `BedrockCohereQueryEmbedder` replaces the
|
||||
SHA-256 hash embedder for the similarity fallback path. It has been
|
||||
import-checked only — **never run against Bedrock** — so the fallback path
|
||||
remains unverified end to end. The section route does not depend on it.
|
||||
|
||||
Verification actually run: ai-service **37 passed, 3 skipped** (22 before, +15);
|
||||
ingestion **296 passed** (unchanged, checked for regression); `ruff --select
|
||||
F,E9,B,ARG` over `rag/`, `adapters/`, `bootstrap.py`, `config.py` and `tests/`
|
||||
— **all checks passed**; section-route evaluation against the live collection
|
||||
160/160; human-written golden questions 16/16.
|
||||
|
||||
Not established: multi-attribute questions ("liều dùng và chống chỉ định") pick
|
||||
the longest phrase, which is deterministic but arbitrary; phrase coverage
|
||||
beyond these 16 human questions is unmeasured; and none of this speaks to
|
||||
whether the retrieved text is clinically correct.
|
||||
|
||||
## 2026-08-04 (afternoon) — First real embeddings exist; retrieval measured at 54% and the cause is not what the small sample said
|
||||
|
||||
The corpus is embedded for the first time. Bedrock IAM was opened on the
|
||||
owner's explicit instruction, all 15,100 chunks were embedded with
|
||||
`cohere.embed-v4:0`, loaded into Qdrant, and **cloud access was then revoked
|
||||
and proven revoked** before the owner's 17:00 deadline. Measured spend
|
||||
**~$0.49** of a personal $138 budget.
|
||||
|
||||
**Gate results.** 15,100/15,100 embedded; 15,100 points in `duocthu_v1` over 59
|
||||
batches; collection point count 15,100 — count gate **PASS**. Manifest records
|
||||
`cohere.embed-v4:0`, 1024 dimensions, Cosine, corpus SHA
|
||||
`04a27166eaa255b516829f8364227e65ad700e51446b569609d18b5efd11189c`. Corpus SHA
|
||||
was re-verified against the morning audit before spending: identical, and
|
||||
identical to the post-lint copy, so the 12:05 `chunker.py` edit did not change
|
||||
output.
|
||||
|
||||
**Both providers were probed live before choosing.** Titan v2 and Cohere v4
|
||||
each returned 1024 dimensions with a **measured L2 norm of 1.000000**. That
|
||||
settles a question left open since 2026-08-03: Cohere's `normalized` field was
|
||||
`None` because AWS's docs never state it. It is now measured. Cohere was chosen
|
||||
on two measured grounds — the corpus is Vietnamese and Cohere is explicitly
|
||||
multilingual, and `bedrock_cohere.py` batches 96 texts per request while
|
||||
`bedrock_titan.py` sends one, which at a measured 2.3s per call is ~9.6 hours
|
||||
versus minutes. The $0.41 price difference did not drive it.
|
||||
|
||||
**The retrieval number, and a correction to a claim made earlier the same
|
||||
day.** A 160-case evaluation (20 per section, 8 sections, questions generated
|
||||
from the corpus so labels are structural) measured **hit@1 0.544, hit@3 0.663,
|
||||
hit@5 0.738**. Per section:
|
||||
|
||||
| section | hit@1 |
|
||||
|---|---|
|
||||
| `chong_chi_dinh` | **0.05** (1/20) |
|
||||
| `chi_dinh` | 0.30 |
|
||||
| `tac_dung_khong_mong_muon` | 0.40 |
|
||||
| `lieu_luong_va_cach_dung` | 0.60 |
|
||||
| `qua_lieu_va_xu_tri` | 0.65 |
|
||||
| `than_trong` | 0.65 |
|
||||
| `tuong_tac_thuoc` | 0.80 |
|
||||
| `thoi_ky_mang_thai` | 0.90 |
|
||||
|
||||
An earlier 15-case run gave a similar headline (0.533) but led to the **wrong
|
||||
diagnosis**: four of its seven failures were contraindication questions
|
||||
answered with indications, so the cause was reported as embedding weakness at
|
||||
negation. At 160 cases that pair accounts for only **3** confusions. The
|
||||
dominant mechanism is different and larger: **`duoc_ly_va_co_che_tac_dung`
|
||||
absorbs questions from every other section** — 10 from adverse effects, 8 from
|
||||
contraindications, 7 from dosage, 5 from indications. It is the largest section
|
||||
(1,896 chunks) and describes the drug in general terms, so it sits close to
|
||||
almost any question about that drug. This is the small-sample failure mode
|
||||
CLAUDE.md warns about, reproduced on this project.
|
||||
|
||||
**Re-embedding cannot fix this, and the capability to fix it already exists.**
|
||||
Verified by reading the code, not assumed: `apps/ai-service/adapters/qdrant.py`
|
||||
`search()` filters on `drug_id` only and lets vector similarity choose the
|
||||
chunk; `rag/routing.py` resolves drug and intent but **not section**; and
|
||||
`find_by_payload` — the "return the whole section" method in `ingestion/load/`
|
||||
— is **never called anywhere in `apps/ai-service`**. Attribute questions
|
||||
therefore depend on similarity picking the right section, which is what
|
||||
measures 54%. The fix is to resolve the attribute to a `section_key` and
|
||||
retrieve that section whole; `ATTRIBUTE_TO_SECTION` already exists in
|
||||
`embed/benchmark_local.py`.
|
||||
|
||||
**A silent-failure hazard found and closed.** `apps/ai-service` embedded
|
||||
queries with `LocalHashQueryEmbedder` — SHA-256 of tokens, explicitly plumbing
|
||||
only — while the collection now holds Cohere vectors. Querying across those two
|
||||
spaces returns hits and raises nothing; the results are simply meaningless.
|
||||
`BedrockCohereQueryEmbedder` was added and wired behind
|
||||
`EMBEDDING_PROVIDER=cohere-v4`. **It has only been import-checked — never run
|
||||
against Bedrock**, because cloud access was revoked first, as instructed.
|
||||
|
||||
**Two operational lessons, both paid for.** `bedrock_runtime.py` set no boto3
|
||||
timeout, so a single throttled response held a socket open for over five
|
||||
minutes and stalled the whole run; `connect_timeout=10, read_timeout=60` plus
|
||||
standard retries fixed it. Then the first full run still died at ~14,600/15,100
|
||||
because the retry backoff (2s, 4s) was far shorter than a per-minute token
|
||||
quota needs. The disk cache made that survivable: the resumed run recorded
|
||||
**14,977 cache hits and 123 misses**, so only 123 vectors were paid for twice —
|
||||
zero, in fact, since the first run's work was already saved.
|
||||
|
||||
**Cloud shutdown, verified rather than asserted.** Both policies detached and
|
||||
deleted; `InvokeModel` and `ListFoundationModels` both now return
|
||||
`AccessDeniedException`. No EC2 instance, no EBS volume, and — because the
|
||||
policy never granted `CreateProvisionedModelThroughput` — no way for this
|
||||
identity to create the one Bedrock resource that bills hourly.
|
||||
|
||||
Not established: retrieval quality is not acceptable for clinical use, no
|
||||
clinician-authored release gate exists, the generated evaluation questions use
|
||||
template phrasing rather than real clinical language, and no LLM answer layer
|
||||
has ever run against real evidence.
|
||||
|
||||
## 2026-08-04 — Chunk schema v4 passes the embedding-readiness gate
|
||||
|
||||
Reviewed the live Claude coordination and its last changes before editing. The
|
||||
delivery plan was objectively stale: it still described schema v2/15,076 chunks,
|
||||
empty embed/load/API modules, embedding before content-safety gates, and allowed
|
||||
unverified inferred table headers as retrieval text. The plan and ADR 0004/0006
|
||||
now put content safety, exact provenance, fail-closed schema validation and local
|
||||
pseudo-vector smoke tests before any provider call. Bedrock remains benchmark-
|
||||
only and requires separate owner approval for any paid/full-corpus run.
|
||||
|
||||
Implemented schema v4 and regenerated the canonical chunk artifact. Retrieval
|
||||
`text` may repeat route/population labels so continuation chunks remain safe in
|
||||
isolation; contiguous `source_text` remains byte-reassemblable and drives exact
|
||||
physical/printed page provenance. `context_labels` records retrieval-only
|
||||
prefixes. All 151 unverified table/formula descriptors embargo `header_row` and
|
||||
cell-like column text. Attachments now carry physical page, printed page,
|
||||
`block_id`, `bbox` and optional crop, and those region references survive the
|
||||
Qdrant adapter and RAG citation response. The loader accepts exactly schema v4,
|
||||
rejects booleans/non-integers/out-of-range pages, and keeps the normalized
|
||||
LF/CRLF-stable corpus identity.
|
||||
|
||||
Canonical artifact measured after regeneration:
|
||||
|
||||
- 15,100 chunks: 14,949 prose + 151 block descriptors;
|
||||
- 4,105,382 `cl100k_base` tokens; 0 chunks above the 800-token ceiling;
|
||||
- all `chunk-ready` gates pass: exact provenance, source uniqueness,
|
||||
reassembly, attachment coverage, descriptor embargo and schema checks all
|
||||
have 0 failures; 151 descriptors match 151 quarantined blocks;
|
||||
- raw file SHA-256:
|
||||
`8dfae08ae6d9222089c5cdb4207a064fe67989f10f7552b555af0aef6331d9a1`;
|
||||
- normalized corpus SHA-256 used by the Qdrant manifest:
|
||||
`04a27166eaa255b516829f8364227e65ad700e51446b569609d18b5efd11189c`.
|
||||
|
||||
Verification actually run:
|
||||
|
||||
- ingestion: **292 passed**; focused post-lint patch: **26 passed**;
|
||||
- AI service with `RUN_INTEGRATION=1`: **25 passed**, including real local
|
||||
Qdrant, PostgreSQL and FastAPI round-trips;
|
||||
- full canonical local smoke with deterministic 4D pseudo-vectors: first and
|
||||
second loads both upserted 15,100 records and both held exactly 15,100 points;
|
||||
manifest hash matched; data and sidecar test collections were removed and
|
||||
Qdrant returned to 0 collections;
|
||||
- Ruff `F,E9,B,ARG` on the files changed for this gate: clean; `git diff
|
||||
--check`: clean (Git only reported Windows LF/CRLF conversion warnings).
|
||||
|
||||
Conclusion: the canonical corpus is **technically READY TO EMBED**, meaning its
|
||||
input/schema/provenance/load plumbing meets the measured gates. This does not
|
||||
authorize a provider call, does not establish retrieval quality for any model,
|
||||
and does not prove whole-book medical accuracy. Human-reviewed clinical eval,
|
||||
table reconstruction, and recall for borderless tables/bar-less formulas remain
|
||||
outside what these gates prove.
|
||||
|
||||
## 2026-08-04 — Real local datastore plumbing, guarded RAG API, and printed-page citations
|
||||
|
||||
Read the live Claude Code process and coordination before editing. Claude owned
|
||||
`ingestion/load/` and `embed/cache.py`; it completed the disk cache, Qdrant
|
||||
port/adapter, idempotent UUID5 upsert, payload indexes and corpus-SHA manifest.
|
||||
Its real local Qdrant scale check loaded all 15,066 chunk records twice with
|
||||
1,024-dimensional deterministic pseudo-vectors and held the point count at
|
||||
15,066. Those vectors are not embeddings and establish no retrieval-quality
|
||||
claim. No Bedrock call, IAM change, or cloud spend occurred.
|
||||
|
||||
Built the first runnable `apps/ai-service` boundary: FastAPI `/health` and
|
||||
`POST /v1/rag/query`, a Qdrant retriever filtered by resolved `drug_id`, a
|
||||
PostgreSQL trace repository plus migration, structured human/non-human scope
|
||||
and fact/recommendation intent gates, parent hydration, quarantine handling,
|
||||
and an extractive answer layer. The answer layer refuses evidence that has only
|
||||
a physical page; citations expose only the printed folio, chunk id and optional
|
||||
source crop. Quarantined tables/formulas return a PDF-verification warning and
|
||||
never auto-extract numeric content.
|
||||
|
||||
Fixed the missing provenance at its source. Chunk schema is now v3 and
|
||||
`cli chunk` reads the real folio map from the 1,668-page PDF. It refuses a
|
||||
monograph whose physical range cannot be mapped, and `chunk-ready` has a new
|
||||
`chunk_without_printed_page_range` gate. Regenerated scope: 684 monographs,
|
||||
15,066 chunks (14,915 prose + 151 descriptors), zero oversized, and
|
||||
15,066/15,066 records with a two-value printed-page range. New artifact SHA:
|
||||
`e474c83790b450d3262f532e81abf6526a485e3a98e376413247da23f4619c38`.
|
||||
|
||||
Verification actually run:
|
||||
|
||||
- `python -m pytest -q` and Ruff over `ingestion/`: **258 passed**, lint clean;
|
||||
- `python -m ingestion.cli chunk-ready`: every gate passed, including printed
|
||||
page range 0/0 failures;
|
||||
- ai-service with `RUN_INTEGRATION=1`: **22 passed**, including a real chunk
|
||||
round-trip through local Qdrant, PostgreSQL migration/insert/read-back, and a
|
||||
full FastAPI → Qdrant → guarded citation → PostgreSQL trace round-trip;
|
||||
- local Docker services: PostgreSQL 16 and Qdrant 1.18.3 reachable; integration
|
||||
collections were UUID-scoped and removed after tests;
|
||||
- ArgoCD local: namespace, CRD and seven controller pods are running; the
|
||||
existing unrelated `guestbook` lab app is Synced/Healthy with four history
|
||||
entries. This repo's three Application YAML files parse and point to
|
||||
`master`/the Helm chart, but they are not installed and the chart still has
|
||||
no workload templates, so project sync/rollback was not performed.
|
||||
|
||||
Still open: no real embedding exists, no full canonical Qdrant collection can
|
||||
serve semantic search, `population_tags` are absent, no clinician-authored
|
||||
release-gate cases exist, and the API currently has no production answer/query
|
||||
embedding provider. The local hashing provider is explicitly plumbing-only.
|
||||
|
||||
## 2026-08-04 — Load stage built and proven against a real Qdrant; bbox rounding found
|
||||
|
||||
`ingestion/load/` was a 0-byte `__init__.py`. It now holds the vector-store
|
||||
boundary: a `VectorStore` port, an `InMemoryVectorStore` that is the reference
|
||||
implementation of its contract, and `QdrantVectorStore` as the only module that
|
||||
names `qdrant_client` — imported lazily, the same arrangement that confines
|
||||
boto3 to `bedrock_runtime`. `embed/cache.py` was added alongside it.
|
||||
|
||||
Three design decisions are worth carrying forward.
|
||||
|
||||
The cache key is `(model_id, input_kind, text_sha256)`, not `chunk_id` as
|
||||
§4.A of the delivery plan proposed. Measured reason: `chunks.jsonl` holds
|
||||
15,066 records but only **14,869 distinct texts**, so 197 records (1.31%) are
|
||||
repeats that a chunk-keyed cache would pay for twice. The content key also
|
||||
cannot serve a stale vector after an edit — a changed text is a changed digest,
|
||||
so it is a miss.
|
||||
|
||||
Point ids are `uuid5(chunk_id)`. A random id would make a re-run append a
|
||||
second copy of a dose and nothing would report an error.
|
||||
|
||||
The corpus manifest lives in a `<name>__manifest` sidecar collection rather
|
||||
than a reserved point inside the data collection, because
|
||||
`qdrant_point_count != chunk_count` is a v1 gate and a gate needing an
|
||||
"except the manifest" footnote will eventually be read wrong.
|
||||
|
||||
**Whole-corpus check against a real server.** A local Qdrant **1.18.3** was
|
||||
started from `infra/docker/docker-compose.yml` (local container, no cloud) and
|
||||
all 15,066 real chunk records were loaded with deterministic pseudo-vectors at
|
||||
1,024 dimensions — a check of the loading mechanism, **not embeddings, which
|
||||
still do not exist**. Corpus sha256 `30d5154273e0959a…`. First load: 15,066
|
||||
points in 59 batches, 14.0s, point-count gate PASS. Second load: still 15,066,
|
||||
so idempotency holds at real scale, not only against the fake store.
|
||||
|
||||
**That sha is already stale, which is the point.** `chunks.jsonl` was
|
||||
regenerated at 09:53 the same day — `chunker.py` changed two minutes earlier
|
||||
and every chunk gained `printed_page_range`, 18,229,918 → 18,753,003 bytes,
|
||||
sha now `e474c83790b450d3…`. Re-measured on the new artifact: still **15,066
|
||||
chunks, 0 over the 800-token ceiling** (largest exactly 800), all 15,066
|
||||
carrying `printed_page_range`, 14,915 prose + 151 block descriptors, 197
|
||||
duplicate texts (1.31%) unchanged because only a field was added. Suite
|
||||
**258 passed**. Had the old corpus been embedded and loaded, then the new one
|
||||
loaded into the same collection, two generations would have mixed with no error
|
||||
at query time — A6 is what refuses that, and it now has a real instance rather
|
||||
than a hypothetical one.
|
||||
|
||||
**A sampled check passed and was wrong.** Comparing 5 payloads gave 5/5
|
||||
identical. Scrolling the entire collection instead found **86 of 15,066 chunks**
|
||||
whose payload did not equal its source record. Classifying every differing leaf:
|
||||
**96 differences, all floats, all inside `attachments[].bbox`, maximum absolute
|
||||
delta 5.684e-14**, and **zero** non-float differences — every text, id, page
|
||||
number, page range, token count and boolean round-tripped exactly. A PDF point
|
||||
is 1/72 inch, so that delta cannot move a rendered crop. It is pinned by a
|
||||
regression test that fails if the loss reaches another field or grows past 1e-9.
|
||||
|
||||
The layer responsible was isolated rather than assumed: the source
|
||||
`chunks.jsonl` returns the value exactly, our own `json.dumps`/`loads` returns
|
||||
it exactly, and **Qdrant reached over raw HTTP with no SDK involved** returns it
|
||||
one ULP low. Nothing needs re-chunking — a regenerated corpus would carry the
|
||||
identical value and be rounded identically. Qdrant also stores dense vectors as
|
||||
float32, so precision beyond f32 is discarded at load regardless.
|
||||
|
||||
Cache format was decided on measurements, not preference: 300 real chunk texts
|
||||
at 1,024 dimensions cost **21,098 bytes/record — ~318 MB per model** for the
|
||||
corpus, with a **7.8s** offset-index rebuild per open. float32 `.npy` (62 MB)
|
||||
and base64 float32 in JSONL (~87 MB) were measured and set aside; append-only
|
||||
JSONL survives an interrupted run and stays readable, which outweighs disk at
|
||||
one or two models. Revisit at three (~950 MB). It lands in
|
||||
`ingestion/data/processed/`, already excluded by `.gitignore:34`.
|
||||
|
||||
**A gap in this work, found and closed the same day.** Payload indexes were
|
||||
created on `drug_id`, `section_key`, `atc_codes` and `chunk_kind` and reported
|
||||
as done — but `VectorStore` had no query method, so all that was really proven
|
||||
is that `create_payload_index` returns without raising. Filtered retrieval is
|
||||
the whole of mode A. `find_by_payload` now exists on the port and both stores,
|
||||
as a `scroll` rather than a `search`: it returns **every** match, never a
|
||||
top-k, because "return the whole section" is the plan's non-negotiable — two of
|
||||
five contraindications reads as a complete list. Verified on a real server: all
|
||||
five parts returned with no leak from the PANTOPRAZOL/OMEPRAZOL pair that
|
||||
measures cosine 1.000 on contraindications; a deliberately 300-part section
|
||||
(above the 256 scroll page) comes back whole so paging cannot truncate; and a
|
||||
real multi-part section from `chunks.jsonl` round-trips to exactly its own
|
||||
chunk ids.
|
||||
|
||||
Tests: **255 passed** with Qdrant running (206 before this work, +49);
|
||||
**247 passed, 8 skipped** with it stopped, so an offline machine and CI see
|
||||
skips rather than failures. After the mode A work and the other worktree's
|
||||
`cli.py` fix the suite stands at **268 passed** and
|
||||
`ruff --select F,E9,B,ARG` reports **no findings at all** across `ingestion/`.
|
||||
|
||||
Still missing, and deliberately so: `printed_page_range` and `population_tags`
|
||||
are not in the payload (open questions to Codex in
|
||||
`coordination/CLAUDE_TASK_2026-08-04.md`); `cli embed` / `cli load` are not
|
||||
wired because `cli.py` is Codex's; and **no real embedding vector has ever been
|
||||
produced** — every vector the load path has carried was synthetic. The Bedrock
|
||||
request shapes remain documentation-derived and unproven.
|
||||
|
||||
Measured cost: **$0**. No Bedrock call, no IAM change, no cloud resource.
|
||||
|
||||
## 2026-08-03 — Bedrock embedding boundary built; IAM diagnosed, not yet opened
|
||||
|
||||
`ingestion/embed/` was an empty `__init__.py`. It now holds the provider
|
||||
boundary the model benchmark needs: an `EmbeddingProvider` ABC that owns input
|
||||
validation, request-size batching and timing, and three adapters behind it —
|
||||
`amazon.titan-embed-text-v2:0`, `cohere.embed-v4:0`, and `BAAI/bge-m3` as the
|
||||
zero-cost local control. boto3 is named in exactly one module and imported
|
||||
lazily, so the package imports and the whole suite runs with no AWS account.
|
||||
|
||||
Two design points are worth carrying forward. `input_kind` is a required
|
||||
argument, not a keyword: Cohere embeds corpus records and queries into
|
||||
different subspaces, and sending `search_document` for a query raises no error
|
||||
— recall just drops. And `normalized` is three-valued. Titan is asked to
|
||||
normalize and says so; the Bedrock docs never state whether Cohere's float
|
||||
vectors are unit-length, so that field stays `None` instead of guessing, and
|
||||
`embed.probe` prints a *measured* L2 norm to settle it on the first live call.
|
||||
|
||||
The AWS side is diagnosed and stuck. `ai-lab-user` has no inline and no
|
||||
attached user policy; its one group (`AI-Lab-Group`) grants EC2, IAM, ELB and
|
||||
VPC full access and nothing else. There is no `bedrock:*` grant anywhere on
|
||||
the identity — confirmed by running both `list-foundation-models` and
|
||||
`invoke-model` and reading the two `AccessDeniedException` messages. Two
|
||||
least-privilege policies are drafted in `infra/aws/iam/` but **deliberately
|
||||
not applied**: that identity carries `IAMFullAccess` and could attach them
|
||||
itself, which is exactly why it was left to a human.
|
||||
|
||||
Consequence: every request-body shape in the two Bedrock adapters is derived
|
||||
from the AWS user guide (read today) and **has never been accepted by the
|
||||
service**. That is unproven, not verified. Tests: 22 new, all with a stub
|
||||
invoker and zero network; **203 passed** overall, up from 181. Lint clean on
|
||||
every file added (`--select F,E9,B,ARG`); the one remaining finding is a
|
||||
pre-existing `cli.py` import owned by the other worktree.
|
||||
|
||||
Measured cost so far: **$0**. Nothing was embedded, nothing reached Qdrant.
|
||||
|
||||
## 2026-08-03 — Exact hard-10 gate and all-block table chunking experiment
|
||||
|
||||
Extended the isolated table/formula sandbox beyond the 100-page sample. An
|
||||
exact ten-block risk gate covered four cross-page pairs, a merged header, a
|
||||
fragmented fraction bar, and the bar-less ADENOSIN formula; all ten source crops
|
||||
were visually checked. The full run then processed all 151 canonical blocks:
|
||||
141 physical tables, ten formulas, 133 logical table parents, 669 row children,
|
||||
and seven cross-page logical tables.
|
||||
|
||||
Full-scope visual inspection exposed a continuation bug: FAMCICLOVIR p647 and
|
||||
INSULIN p811 repeat their column headers, while other continuation pages start
|
||||
directly with data. The linker now distinguishes these cases; repeated headers
|
||||
are not emitted as data, and INSULIN's changed `Phối hợp` first-column meaning
|
||||
is preserved. Both branches have regressions.
|
||||
|
||||
The expanded, source-derived retrieval suite contains 2,436 cases. With drug
|
||||
and table/formula lane resolved before ranking, deterministic hybrid character
|
||||
TF-IDF measured 94.42% Recall@1, 99.79% Recall@5, and 96.90% MRR. Row questions
|
||||
were 94.82% / 100%; formula questions 100% / 100%. Five ambiguous whole-table
|
||||
questions fell below top five because the same drug owns several near-identical
|
||||
tables; production must clarify or route using an additional table anchor.
|
||||
Neural MiniLM is now opt-in and excluded from the default parsing gate.
|
||||
|
||||
Measured chunk design: table-parent tokens min/median/p90/p95/max =
|
||||
66/188/441/678/1,893; only four of 133 parents exceed 800. Row children are
|
||||
75-token median, 172 p95, 471 max. Keep every logical parent intact, index both
|
||||
parent and header-aware rows, never split a row, and hydrate row hits to the
|
||||
complete parent/source pages. Final checks: **181 tests passed**, readiness
|
||||
20/20, lint clean.
|
||||
|
||||
---
|
||||
|
||||
## 2026-08-03 — 100-page table/formula reconstruction and RAG sandbox
|
||||
|
||||
Built an isolated experiment under `ingestion/scratch/rag-table-pilot` without
|
||||
writing sandbox representations into the canonical corpus. The risk-stratified
|
||||
100-page run reconstructed 120 tables and 10 formula regions, rendered and
|
||||
manually inspected all 130 crops, and linked four tables continued across page
|
||||
pairs 132-133, 646-647, 825-826, and 1373-1374.
|
||||
|
||||
The retrieval router fixes the drug and data lane before vector ranking. On 461
|
||||
source-derived queries, hybrid row+whole character TF-IDF reached 92.62%
|
||||
Recall@1, 98.70% Recall@5, and 95.04% MRR. Cached English-oriented MiniLM was
|
||||
worse (88.29% / 97.18% / 91.92%). Eighteen row-hit answer previews all hydrated
|
||||
to the complete parent Markdown table; eight included both pages of a continued
|
||||
table. A narrow deterministic interval probe passed 172/172 generated cases;
|
||||
this is a mechanics check, not clinical ground truth.
|
||||
|
||||
Visual review exposed one canonical defect: ADENOSIN p147's bar-less printed
|
||||
formula region ended after its numerator and omitted `Nồng độ adenosin
|
||||
(3 mg/ml).` The bar-less band now extends 31pt below its synthetic anchor,
|
||||
capturing the denominator but stopping before `Ví dụ:`; a regression pins that
|
||||
boundary. Canonical artifacts were regenerated after the fix: 684 monographs,
|
||||
11,974 sections, 15,066 chunks, 151 descriptors, 0 unassigned spans, all 20
|
||||
readiness gates passing, **180 tests passed**, and lint clean.
|
||||
|
||||
Decision: JSON grid + Markdown answer view, row and whole-table retrieval, and
|
||||
mandatory parent hydration are viable for the next stage. This remains a
|
||||
retrieval experiment, not production clinical approval; merged-cell semantics,
|
||||
unit/multi-axis reasoning, Vietnamese embedding comparison, borderless/bar-less
|
||||
recall, clinician-authored evals, and final expert review remain open.
|
||||

|
||||
## 2026-08-03 — Whole-corpus parser repair after manual baseline audit
|
||||
|
||||
Implemented and re-ran the parser over all 1,668 pages after manually reading
|
||||
the high-risk baseline outliers. The fixes are structural, with regressions:
|
||||
|
||||
- restored the missing `THUỐC TƯƠNG TỰ HORMON GIẢI PHÓNG GONADOTROPIN`
|
||||
boundary (`Tên chung quốc tế và mã ATC` is its real first anchor), separating
|
||||
pages 1371–1373 from `THUỐC PHIỆN - OPIAT - OPIOID`;
|
||||
- require both physical and inferred printed page bounds, so back-index page
|
||||
1655 can no longer extend ZOLPIDEM's real `[1492, 1494]` range;
|
||||
- keep plain label-shaped text as body when it is an adjacent wrapped
|
||||
continuation in the same PDF block (including NADROPARIN's “không phải là
|
||||
chống chỉ định”);
|
||||
- classify known table cells before headings, putting WARFARIN and IOBITRIDOL
|
||||
dosing tables back under `lieu_luong_va_cach_dung`;
|
||||
- added confirmed heading variants for CLORPHENIRAMIN dosage forms and tetanus
|
||||
toxoid dosing, and real provenance for combined inline fields;
|
||||
- made verified formula bands column-aware: NETILMICIN opposite-column prose
|
||||
is retained while AMPICILIN's gutter-adjacent formula stays quarantined;
|
||||
- visually inspected all **151/151 unique table/formula regions** against the
|
||||
rendered PDF; every region is genuinely 2D and remains quarantined;
|
||||
- emit every physical table/formula region atomically at its first stream
|
||||
occurrence, fixing split/contradictory ownership on CAPECITABIN, IMATINIB,
|
||||
CARBOPLATIN, NETILMICIN, and TRASTUZUMAB;
|
||||
- route explicit `Bảng N. Điều chỉnh liều ...` appendices back to dosage even
|
||||
when the book prints them after `Tên thương mại` (CAPECITABIN p309);
|
||||
- added readiness gates for every individual section part's source-span IDs
|
||||
and duplicate physical-region IDs.

## 2026-08-03 — Independent re-verification, a redundant rule in my own uncommitted fix, a provenance defect, and the measurements a retrieval design has to be built on
|
||||
|
||||
No code was changed in this session: the four files from the previous round
|
||||
are still uncommitted and under external review (Codex). Everything below is
|
||||
measurement, and the numbers live nowhere else — the investigation scripts
|
||||
were deleted per the repo rule, so this entry is the record.
|
||||
|
||||
### 1. Re-verified the whole tree from scratch
|
||||
|
||||
| check | command | result |
|
||||
|---|---|---|
|
||||
| tests | `python -m pytest -q` | **164 passed**, 39.31s |
|
||||
| lint | `ruff check --select F,E9,B,ARG .` | clean |
|
||||
| gates | `cli chunk-ready` | **18/18 PASS**; 683 monographs, 11,966 sections, 8,212,880 chars, 167 quarantined blocks |
|
||||
| recall/precision | `cli validate --pdf …` | 683 detected, 705 ground truth, **96.0% (677/705) / 99.1%** |
|
||||
| span ledger | `cli coverage --pdf …` (re-run) | 252,799 spans after merge, 9,398,772 chars, **unassigned 0** |
|
||||
| reproducibility | `cli run` → sha256 | **byte-identical** to `monographs.jsonl` (`84f41d96…`) |
|
||||
| reproducibility | `cli chunk` → sha256 | **byte-identical** to `chunks.jsonl` (`63472db4…`); 15,076 chunks (14,909 prose + 167 descriptors), 0 oversized, 4,072,725 tokens (cl100k_base) |
|
||||
|
||||
Recall rose 92.9% → 96.0% because of the uncommitted back-index rejoin, and
|
||||
the mechanism is the denominator: 725 → 705 ground-truth entries once wrapped
|
||||
fragments stop counting as entries. The detector did not improve.
|
||||
|
||||
**Not re-run: `cli residual-ink`.** `residual_ink.json` is dated 2026-08-01
|
||||
12:03, before the 17:36 assembler edits. Its stored contents (3,931 regions,
|
||||
no `unclassified` kind) are last session's numbers, not this session's.
|
||||
|
||||
**Doc drift found:** `docs/verification-strategy.md` quotes 252,733 spans /
|
||||
177,679 `normalized_text` / 12,764 `heading`; measured today 252,799 /
|
||||
177,754 / 12,752. The `unassigned = 0` conclusion still holds.
|
||||
|
||||
### 2. The x0 geometry change in the uncommitted diff is redundant
|
||||
|
||||
Assembled the whole book four times with the two new rules toggled:
|
||||
|
||||
| variant | monographs | sections | chars |
|
||||
|---|---|---|---|
|
||||
| current (x0 + italic) | 683 | 11,966 | 8,212,880 |
|
||||
| **old x1 rule + italic** | 683 | 11,966 | **8,212,880** — 0 differences of any kind |
|
||||
| x0, no italic | 683 | 11,966 | 8,212,844 (3 sections differ) |
|
||||
| x1, no italic (= `bc01782`) | 683 | 11,966 | 8,212,780 (9 sections differ, 11,014 char delta) |
|
||||
|
||||
The italic rule alone recovers all 9 sections (CEFAZOLIN dosing 1,062 →
|
||||
5,620 chars; CALCI LACTAT `than_trong` 582 → 1,504, `tuong_tac_thuoc` 2,346 →
|
||||
1,439). The x0 rule alone recovers 6 of 9 and adds **nothing** on top of the
|
||||
italic rule.
|
||||
|
||||
Worse, the justification is wrong: the real NEVIRAPIN span on physical page
|
||||
1045 is `TimesNewRomanPS-ItalicMT` (verified by reading the span's font), so
|
||||
the italic rule is what fixes that page — not the 0.01pt overlap the code
|
||||
comment and the new test's docstring credit. The test itself is valid but
|
||||
pins the geometric rule only, because the `_span()` fixture helper never
|
||||
produces an italic font. **Either keep the x0 rule as defence-in-depth with
|
||||
an honest comment, or revert it — but the current comment overstates it.**
|
||||
|
||||
### 3. `source_page_range` is wrong for 13 of 683 monographs
|
||||
|
||||
Section-level provenance (`parts`) is correct everywhere; the monograph-level
|
||||
page range is not. 12 monographs overshoot by +1 page; **ZOLPIDEM declares
|
||||
`[1492, 1655]` while every one of its sections comes from 1492-1494** — a
|
||||
164-page claim reaching into the back index.
|
||||
|
||||
Root cause for ZOLPIDEM, confirmed: physical page 1655 (printed 1656, back
|
||||
matter) carries a **bold** span reading exactly `Tương tác thuốc`, which
|
||||
`_classify` emits as a `_SectionEvent`, and the `_SectionEvent` branch at
|
||||
`segment/assembler.py:496` updates `source_page_range[1]` with **no
|
||||
`in_monograph_range` guard** — unlike the `_TextEvent` branch at line 511.
|
||||
Verified that **0 spans past physical 1495 pass `in_monograph_range`**, so no
|
||||
text was contaminated and `empty_section` is still 0. The defect is confined
|
||||
to one provenance field.
|
||||
|
||||
The +1 cause is **not isolated** — it is not lifted tables (all 12 have
|
||||
`tables: []`); the likely candidate is a next-page boilerplate span bumping
|
||||
the range before being excluded, but that was not measured.
|
||||
|
||||
### 4. Corpus profile — what a retrieval design actually has to work with
|
||||
|
||||
- **13 of 19 fields have p90 < 1,500 chars**, i.e. the whole section fits one
|
||||
chunk. Only four routinely need splitting: `duoc_ly` (p90 4,939, max
|
||||
14,099), `lieu_luong` (4,873 / 14,197), `than_trong` (2,419), `tuong_tac`
|
||||
(2,147). Confirms ADR 0004 on the cleaned corpus.
|
||||
- **ATC**: 668/683 (97.8%) carry ≥1 code, **171 (25.0%) carry more than one**,
|
||||
max 20, 1,043 distinct codes.
|
||||
- **`ten_thuong_mai` present in 492 (72%)** monographs.
|
||||
- **The back index holds 344 `X - xem Y` lines** — brand → generic aliases —
|
||||
which `parse_back_index` currently discards wholesale (correct for
|
||||
validation, but this is the highest-value retrieval asset in the book,
|
||||
because clinicians type brand names).
|
||||
- **401 `xem [thêm] mục/chuyên luận` phrases across 261 monographs**; a chunk
|
||||
containing one is useless retrieved alone.
|
||||
- **Dosing population markers**: `Trẻ em` 53%, `Người lớn` 51%, `Người cao
|
||||
tuổi` 15%, `Trẻ sơ sinh` 8%, `Suy thận` 8%, `Suy gan` 6% of 682 dosing
|
||||
sections — real sub-section boundaries, better split points than token
|
||||
windows.
|
||||
- **167 quarantined blocks, 129 (77%) inside `lieu_luong_va_cach_dung`** —
|
||||
the most dangerous field is the one the tables were lifted out of.
|
||||
|
||||
### 5. Cross-drug confusability — the number that decides the architecture
|
||||
|
||||
First hypothesis (much repeated boilerplate across drugs) was **refuted**:
|
||||
only **171 of 11,966 sections** share exact text with another drug (1.4%), and
|
||||
the six heavy clinical fields are 100% distinct.
|
||||
|
||||
Then measured, per field, each drug's TF-IDF cosine against its *nearest other
|
||||
drug*. **This is a lexical proxy, not an embedding measure** — it bounds the
|
||||
problem from one side only.
|
||||
|
||||
| field | median | p90 | p99 | max | drugs with NN > 0.7 |
|
||||
|---|---|---|---|---|---|
|
||||
| `lieu_luong_va_cach_dung` | 0.314 | 0.455 | 0.631 | 0.836 | 4 (0.6%) |
|
||||
| `tuong_tac_thuoc` | 0.284 | 0.461 | 0.870 | 0.984 | 18 (2.8%) |
|
||||
| `tac_dung_khong_mong_muon` | 0.300 | 0.437 | 0.856 | 1.000 | 13 (1.9%) |
|
||||
| `chi_dinh` | 0.408 | 0.637 | 0.885 | 0.924 | 31 (4.5%) |
|
||||
| `chong_chi_dinh` | 0.346 | 0.633 | 0.898 | **1.000** | 37 (5.4%) |
|
||||
|
||||
Named pairs: `PANTOPRAZOL ↔ OMEPRAZOL` (contraindications **1.000**,
|
||||
indications 0.913) · `BENZATHIN PENICILIN G ↔ PHENOXYMETHYLPENICILIN`
|
||||
(contraindications **1.000**) · `DIGOXIN ↔ DIGITOXIN` (0.891 / 0.911) ·
|
||||
`NATRI NITRIT ↔ NATRI THIOSULFAT` (dosing 0.631 — two different steps of the
|
||||
same cyanide-antidote protocol) · `IOBITRIDOL ↔ ACID IOXAGLIC` (0.984) ·
|
||||
`ESTRIOL ↔ ESTRON` · `GLICLAZID ↔ GLIMEPIRID` · `NAPHAZOLIN ↔ OXYMETAZOLIN`.
|
||||
|
||||
Name layer: **19 drug names are a substring of another drug name**
|
||||
(`CLOROTHIAZID` in `HYDROCLOROTHIAZID`, `EPHEDRIN` in `PSEUDOEPHEDRIN`,
|
||||
`LORATADIN` in `DESLORATADIN`, `ATROPIN` in `HOMATROPIN HYDROBROMID` — all
|
||||
genuinely different drugs), and 106 of 683 names share a 6-character prefix
|
||||
across 38 clusters.
|
||||
|
||||
**Conclusion drawn from this, for the retrieval design: vector similarity must
|
||||
never be allowed to choose the *drug* — only which passage within an
|
||||
already-resolved drug.** The dangerous confusions are concentrated in a
|
||||
small, enumerable set of same-class pairs, which is exactly the population
|
||||
this project's verification strategy says to census rather than sample.
|
||||
|
||||
### Not done yet / next up
|
||||
|
||||
Sequenced in **`docs/v1-delivery-plan.md`** (written this session): a
|
||||
two-week plan to a running v1, scoped down to two deployables (`web` +
|
||||
`ai-service`) because the four NestJS services measure 0 `.ts` files each.
|
||||
The items below are the ones that plan depends on.
|
||||
|
||||
- The confusable-pair census must become a **committed fixture produced by
|
||||
production code** (`ingestion/validation/`), not a deleted scratch script.
|
||||
Until then these numbers are only in this entry.
|
||||
- ADR 0007 (retrieval architecture) not written. Proposed content: vectors
|
||||
never pick the drug; the unit returned to the LLM is the **complete
|
||||
section** (enabled by `section_not_reassemblable_from_chunks = 0`, because a
|
||||
partial contraindication list reads as "no contraindication"); and eval
|
||||
split in two — **routing** correctness (ground truth derivable from the
|
||||
corpus itself, 683 × 19 pairs, no human needed) versus **content**
|
||||
correctness (requires a clinician; cannot be self-generated without
|
||||
fabricating evidence).
|
||||
- Entity/alias layer (683 canonical names + 344 back-index aliases + 492
|
||||
`ten_thuong_mai` + 1,043 ATC codes) — zero-regret, needed by every
|
||||
architecture, must use longest-exact-match because of the 19 substring
|
||||
traps.
|
||||
- `residual-ink` re-run; `verification-strategy.md` numbers re-synced;
|
||||
regression test for `parse_back_index` (still has none); the
|
||||
`source_page_range` guard; the x0-rule comment decision.
|
||||
- Open question for the user, not a technical one: this is the **2018
|
||||
edition**; the 3rd edition (2022) exists. For a document with legal force
|
||||
over prescribing, staying on 2018 should be a deliberate decision, and it
|
||||
makes edition-independence a real requirement for the pipeline.
|
||||
- Still untouched: `embed/`, `load/`, Qdrant, `ai-service`, and the general
|
||||
chapters (printed 37-98) and appendices (printed 1497-1528), which remain
|
||||
outside the corpus entirely.
|
||||
|
||||
## 2026-08-01 (cont'd, 7) — "still errors?" — yes: two more real content-loss bugs, both in dosing sections
|
||||
|
||||
Asked whether errors remained after the previous round, the honest answer was
|
||||
that this session has found real defects every time it looked one level
|
||||
deeper. It looked again, and found two more.
|
||||
|
||||
**1. Chunks ended on a bare population label, with the dose in the next
|
||||
chunk.** `split_sentences` treats `:` as a sentence boundary and
|
||||
`_OPENS_SENTENCE` accepts a digit, so `"Người lớn: 500 mg mỗi 8 giờ."` splits
|
||||
after the colon. When the packer flushed at that point, the chunk ended on the
|
||||
label. Measured: **38 prose chunks**, e.g. AMOXICILIN's ending on a Lyme
|
||||
indication followed by a bare `Người lớn:`. Retrieval on that chunk returns a
|
||||
population with no dose; on the next, a dose with no population. Outlier item
|
||||
17 counted population markers on 1,121 of ~1,400 monograph pages, so this is
|
||||
the common shape, not an edge case. The packer now carries trailing label
|
||||
atoms into the next part instead of flushing on them: **38 → 2**, and chunks
|
||||
ending on any colon **721 → 19**.
|
||||
|
||||
**2. A section name printed mid-line was swallowed as a heading — real text
|
||||
loss, in dosing sections.** Chasing the last 2 of those 38 showed the defect
|
||||
was not in chunking at all. CISPLATIN (physical page 402) prints
|
||||
`Suy thận: Chống chỉ định.` inside `liều lượng và cách dùng`; the second half
|
||||
is itself a section name, so it was matched as a heading. The result: the
|
||||
renal-impairment contraindication **disappeared from the dosing text** and the
|
||||
section ended on a bare `Suy thận:`. ISOPRENALIN had the same shape. Same
|
||||
family as the FLUOROURACIL bug fixed earlier today, but that rule only covered
|
||||
a label directly *under* a heading and could not see this one.
|
||||
|
||||
Fixed geometrically: a real section heading opens its line, so a non-bold
|
||||
section name with another span printed to its left is body text. "To the left"
|
||||
is checked properly — same page/block/line *and* `previous.x1 <= span.x0` —
|
||||
because the synthetic test fixtures place every span at identical coordinates,
|
||||
and a looser check passed on real data while breaking the AMITRIPTYLIN
|
||||
inline-value case.
|
||||
|
||||
Verified after the fix: CISPLATIN's dosing section contains
|
||||
`Suy thận: Chống chỉ định.` again, ISOPRENALIN's `Trẻ em:` is followed by its
|
||||
doses, and `chong_chi_dinh` is no longer polluted. Monograph and section counts
|
||||
unchanged at 683 / 11,966 — nothing was traded away for the recovery.
|
||||
|
||||
**State:** 18/18 gates pass, **163 tests** (was 161), ruff F/E9/B/ARG clean,
|
||||
15,077 chunks with 0 over the ceiling, 8,212,780 section characters.
|
||||
|
||||
**Standing conclusion, worth writing down:** every round of "is it clean now?"
|
||||
this session has ended with real defects found — five in the previous round,
|
||||
two in this one, and four of the previous five were in code written the same
|
||||
day. The gates and tests prove what those instruments can see. They do not
|
||||
prove the corpus is correct, and the largest unmeasured area is unchanged:
|
||||
content accuracy against the source, with no human-reviewed ground truth for
|
||||
8.2M characters.
|
||||
|
||||
## 2026-08-01 (cont'd, 6) — Bug hunt after declaring "clean": the token count was wrong by 2x, 14.7% of chunks were over the ceiling, and two stage boundaries measured different pipelines
|
||||
|
||||
I had just reported the tree as clean. It was not. Going looking properly
|
||||
found five real defects, four of them in code written earlier the same day.
|
||||
|
||||
**1. `estimate_tokens` was wrong by a factor of two, and the number it
|
||||
produced was reported.** ADR 0004 sized chunks with `len(text) // 4`,
|
||||
described honestly as an estimate. Measured against `cl100k_base` on the real
|
||||
corpus:
|
||||
|
||||
| | |
|
||||
|---|---|
|
||||
| estimate (chars/4) | 2,115,427 tokens |
|
||||
| real tokenizer | **4,093,440 tokens** |
|
||||
| real/estimate | median **1.95**, p95 2.50, max **6.0** |
|
||||
| oversized by estimate | **0** |
|
||||
| oversized in fact | **1,884 of 12,838 = 14.7%**, largest 1,645 tokens |
|
||||
|
||||
Vietnamese diacritics cost several byte-pair tokens each. "0 oversized" was
|
||||
reassuring and false. `chunk/tokens.py` now counts with the real tokenizer,
|
||||
injected so the chunking logic stays testable without it, with a fallback of
|
||||
chars/2 that errs small rather than large.
|
||||
|
||||
**2. The packer could exceed the ceiling on its own.** Two causes, both
|
||||
measured on VORICONAZOL's `tương tác thuốc`: an atom of 710 tokens was left
|
||||
whole because it was under the 800 ceiling, and the overlap builder added
|
||||
whole atoms until the running total *passed* the budget, so a 251-token atom
|
||||
produced a 273-token overlap against a 65-token setting. 273 + 710 = 983.
|
||||
Atoms are now split against the 650 target, leaving room for overlap, and the
|
||||
overlap stops *before* exceeding its budget.
|
||||
|
||||
**3. An over-long comma list was left as one atom.** VORICONAZOL's
|
||||
interaction list is one "sentence" hundreds of drug names long. Truncated by
|
||||
an embedding model it reads as "this drug is not listed" — a false negative
|
||||
in the direction that matters. Split at commas, which is lossless for a list.
|
||||
|
||||
After 1-3: **0 chunks over the ceiling**, verified by an independent tiktoken
|
||||
re-count of the written file, not by the pipeline's own number. 15,049 chunks
|
||||
(was 12,838 — the rise is real sub-chunking that should have happened all
|
||||
along).
|
||||
|
||||
**4. `cli validate` measured a different pipeline than `cli run`.** It used
|
||||
the raw span stream (no transcription repair) and passed no table regions, so
|
||||
recall/precision described a build that is not the one producing the output —
|
||||
the same class of mismatch already fixed for `coverage`. Now shares
|
||||
`_extracted_and_repaired_spans` and `_region_index`. Result after the fix is
|
||||
unchanged at 92.9% / 99.1%.
|
||||
|
||||
**5. `chunk/io.py` dropped `SectionPart` when reading monographs back**, so
|
||||
per-part provenance died at the stage boundary — against CLAUDE.md's explicit
|
||||
rule. Now carried: 12,290 parts across 11,966 sections.
|
||||
|
||||
**Two new gates, and the gate itself was wrong twice before the data was.**
|
||||
`section_not_reassemblable_from_chunks` rebuilds each section from its own
|
||||
chunks by removing the deliberate overlap and compares. First version joined
|
||||
chunk texts with a newline and reported **734** sections missing — the first
|
||||
one it named was present. Second version probed a 60-character head and
|
||||
reported **1**, NAPROXEN, where the probe straddled an overlap seam that
|
||||
legitimately repeats text. The working version compares with whitespace
|
||||
removed, because each split seam loses exactly one space to `.strip()`
|
||||
(measured on ABACAVIR: two single spaces in a 4,232-character section,
|
||||
nothing else). It proves no character of content is lost, reordered or

duplicated beyond the intended overlap. **0.**
|

|

**Also fixed:** all 8 real lint findings (`ruff --select F,E9,B,ARG`) — five
|

unused imports and three `zip()` calls without explicit `strict=`. The zips
|
||||
were the adjacent-pair idiom and not bugs; `strict=False` now says so. And
|
||||
the transcription splice could leave a fragment holding only a space, which
|
||||
showed up as two `whitespace_only` spans; dropped, and proven inert by the
|

sha256 over every section's text being byte-identical before and after
|

(`6af13301…`).
|

**State after the hunt:** 18/18 gates pass (10 corpus + 8 chunk), 161 tests

# Kế hoạch giao bản v1 chạy được — 2 tuần
|
||||
|
||||
**Lập ngày 2026-08-03. Hạn: ~2026-08-17.**
|
||||
|
||||
## Cập nhật bắt buộc 2026-08-04 — gate trước embedding
|
||||
|
||||
Phần hiện trạng ngày 2026-08-03 bên dưới được giữ làm lịch sử, nhưng không còn
|
||||
được dùng để quyết định chạy embedding. Candidate schema v4 đã được tạo và đo
|
||||
trên toàn corpus: **15.100 chunks** (14.949 prose + 151 block descriptor),
|
||||
4.105.382 token `cl100k_base`, 0 chunk quá 800 token. Candidate chưa phải artifact
|
||||
canonical cho đến khi vượt toàn bộ gate và thay thế `data/processed/chunks.jsonl`.
|
||||
|
||||
Thứ tự bắt buộc từ đây:
|
||||
|
||||
1. khóa an toàn nội dung: label/liều không tách rời; `source_text` ghép lại đúng
|
||||
section; toàn bộ header bảng chưa kiểm chứng bị embargo khỏi text embedding;
|
||||
2. khóa provenance: range vật lý và range trang in phải chính xác theo từng chunk;
|
||||
attachment phải mang `block_id`, `bbox`, trang vật lý và trang in;
|
||||
3. khóa consumer: loader chỉ nhận đúng schema v4, từ chối schema cũ/mới và metadata
|
||||
sai kiểu hoặc sai miền;
|
||||
4. chạy test + `chunk-ready` trên candidate; chỉ khi mọi gate bằng 0 mới tái sinh
|
||||
artifact canonical và ghi SHA-256;
|
||||
5. smoke-test local bằng vector giả để kiểm plumbing/idempotency; xóa collection test;
|
||||
6. **chỉ sau phê duyệt riêng của chủ dự án** mới gọi provider có chi phí hoặc chạy
|
||||
embedding toàn corpus. Bedrock chỉ dùng để tìm hiểu/benchmark, không phải runtime
|
||||
dependency.
|
||||
|
||||
Định nghĩa **READY TO EMBED**: canonical là schema v4; toàn bộ readiness gate bằng
|
||||
0; test ingestion và AI service liên quan đều pass; SHA corpus đã ghi; Qdrant không
|
||||
còn collection test; không có header/cell chưa kiểm chứng trong embedding text.
|
||||
Trạng thái này chỉ cho phép bước chuẩn bị kỹ thuật, không tự động cấp phép phát sinh
|
||||
chi phí.
|
||||
|
||||
Quy ước của tài liệu này, theo đúng luật trong `CLAUDE.md`:
|
||||
|
||||
- **(đo)** = đã chạy thật trong phiên 2026-08-03, lệnh và kết quả ghi trong
|
||||
`docs/progress-log.md`.
|
||||
- **(ước lượng)** = phỏng đoán, chưa đo, có thể sai. Mọi con số thời gian
|
||||
trong tài liệu này đều là ước lượng — không có ngoại lệ.
|
||||
- `[chờ xác nhận]` = phụ thuộc quyết định của người chủ dự án, không được tự
|
||||
chọn thay.
|
||||
|
||||
Ước lượng thời gian giả định **1 người, ~6 giờ làm việc hiệu quả/ngày, 10
|
||||
ngày công**. Nếu thực tế là bán thời gian thì mục §8 (ngoài phạm vi) phải
|
||||
dài thêm, chứ không phải ép các mục còn lại chạy nhanh hơn.

## 0. Hiện trạng — đo, không phải nhớ
|
||||
|
||||
| Thành phần | Trạng thái |
|
||||
|---|---|
|
||||
| `ingestion/` extract → segment → chunk | Baseline 2026-08-03 đã hoàn thành; candidate schema v4 ngày 2026-08-04 có 15.100 chunks và đang chờ gate cuối trước khi trở thành canonical |
|
||||
| `ingestion/embed/` | Đã có provider ports, cache, local BGE-M3 và adapter Bedrock; chưa được phép chạy provider trả phí/full corpus |
|
||||
| `ingestion/load/` | Đã có validation fail-closed schema v4, manifest/hash, upsert idempotent và adapter Qdrant; còn nghiệm thu artifact canonical mới |
|
||||
| `apps/ai-service/` | Đã có FastAPI/RAG, adapter Qdrant/Postgres, guardrails và citation theo region; còn nghiệm thu tích hợp trên corpus canonical mới |
|
||||
| `apps/api-gateway`, `auth-service`, `chat-service`, `user-service` | **0 file `.ts`** mỗi service |
|
||||
| `apps/web/` | 18 file, chat UI + PDF split-view chạy được, backend là mock (`sendChatMessage` = `setTimeout(400ms)` + fixture) |
|
||||
| `packages/shared-types` | DTO `ChatMessage` / `Citation` đã có |
|
||||
| Dockerfile | **0 cái trong toàn repo** |
|
||||
| `infra/helm/medical-chatbot/templates/` | **rỗng**, chỉ có `.gitkeep`; `values.yaml` chỉ có 2 dòng comment |
|
||||
| `infra/argocd/applications/{dev,staging,prod}/app.yaml` | Có sẵn, trỏ `path: infra/helm/medical-chatbot`, `targetRevision: master`; còn 3 `TODO` (project, repoURL, destination cluster) |
|
||||
| `infra/docker/docker-compose.yml` | Chỉ có `postgres`, `qdrant`, `redis` — không có service ứng dụng |
|
||||
| CI | Chỉ có `infra/ci/github-actions/README.md` |
|
||||
| Tracing | Không có gì |
|
||||
|
||||
**Tài sản không nằm trong repo nhưng có thật**: quyền truy cập k3s của team,
|
||||
ArgoCD (admin), kubeconfig đã hoạt động. Đây là lý do phần deploy không bắt
|
||||
đầu từ số 0.

|
||||
## 1. Phạm vi v1 — cắt gì, và vì sao đó không phải "ăn bớt"
|
||||
|
||||
### Cắt khỏi v1: `api-gateway`, `auth-service`, `user-service`, `chat-service`
|
||||
|
||||
Bốn service này cộng lại đang là **0 dòng code (đo)**. Viết cả bốn bằng
|
||||
NestJS trong 2 tuần, song song với mọi việc khác, là thứ giết deadline — và
|
||||
không service nào trong bốn cái đó **thêm năng lực** cho bản chạy được:
|
||||
gateway là định tuyến, auth là đăng nhập, user là hồ sơ, chat là lịch sử.
|
||||
|
||||
Thay thế trong v1:
|
||||
|
||||
| Nhu cầu | Cách làm trong v1 | Nợ kỹ thuật để lại |
|
||||
|---|---|---|
|
||||
| Chặn người ngoài | Basic-auth ở ingress (hoặc header token dùng chung) | Không có tài khoản cá nhân, không phân quyền |
|
||||
| Lịch sử hội thoại | `ai-service` ghi thẳng Postgres, bảng `conversation` / `message` | Không có service riêng, không có sync đa thiết bị |
|
||||
| Hồ sơ người dùng | Không có | Toàn bộ |
|
||||
| Định tuyến | `web` gọi thẳng `ai-service` | Không có rate-limit/gateway policy tập trung |
|
||||
|
||||
Điều này **không mâu thuẫn** với Clean Architecture đã ghi trong `CLAUDE.md`:
|
||||
domain là retrieval + grounding, còn auth/history/profile là hạ tầng. Tách
|
||||
chúng ra service riêng sau này không phải sửa domain — nếu domain được viết
|
||||
đúng ngay từ đầu (xem §4.C).
|
||||
|
||||
### Ba thứ tuyệt đối không cắt, dù trễ
|
||||
|
||||
1. **Vector không bao giờ được chọn *thuốc*.** Danh tính thuốc resolve tất
|
||||
định. Lý do đo được: cặp `PANTOPRAZOL ↔ OMEPRAZOL` có cosine chống chỉ
|
||||
định **1,000**, `DIGOXIN ↔ DIGITOXIN` 0,891/0,911, `NATRI NITRIT ↔ NATRI
|
||||
THIOSULFAT` 0,631 ở phần liều. Để cosine chọn thuốc là chấp nhận rủi ro
|
||||
trả nhầm liều của thuốc khác.
|
||||
2. **Trả về cả section, không phải top-k mảnh.** Trả 2/5 chống chỉ định
|
||||
nguy hiểm hơn trả 0, vì thiếu sẽ bị đọc thành "không có chống chỉ định".
|
||||
Đã có bảo chứng: gate `section_not_reassemblable_from_chunks` = 0.
|
||||
3. **Không đọc số liều từ 167 block quarantine** (129 block = 77% nằm trong
|
||||
`lieu_luong_va_cach_dung`) — phải hiện ảnh crop trang gốc.
|
||||
|
||||
---
|
||||
|
||||
## 2. Giả định phải xác nhận trước khi bắt đầu
|
||||
|
||||
| # | Giả định mặc định của kế hoạch này | Nếu khác thì đổi gì |
|
||||
|---|---|---|
|
||||
| GĐ-1 | Đích deploy là **k3s của team qua ArgoCD** | Nếu chỉ cần `docker-compose` demo: bỏ §4.E5-E8, tiết kiệm ~2 ngày (ước lượng) |
|
||||
| GĐ-2 | "Tracing" = **trace LLM/RAG** (câu hỏi → thực thể resolve → chunk lấy ra → prompt → câu trả lời → latency/token) | Nếu là distributed tracing OTel giữa các service: v1 chỉ có 2 service nên giá trị thấp; xem §4.F |
|
||||
| GĐ-3 | Runtime giữ **provider-agnostic**; Bedrock chỉ để benchmark embedding, không là dependency bắt buộc | Không gọi Bedrock/full corpus hoặc tạo chi phí nếu chưa có phê duyệt riêng; local smoke vector chỉ kiểm tra plumbing, không dùng làm số đo retrieval |
|
||||
| GĐ-4 | Dùng **bản 2018** đang có | Chuyển sang bản 2022 = chạy lại toàn bộ ingestion + validate lại từ đầu; **không khả thi trong 2 tuần** |
|
||||
| GĐ-5 | Câu hỏi runtime **có thể chứa thông tin bệnh nhân** | Nội dung sách là tài liệu công khai nên embedding offline không rò rỉ gì; nhưng **câu hỏi của bác sĩ thì có thể** — cần quyết định chính sách trước khi mở cho người thật dùng `[chờ xác nhận]` |
|
||||
|
||||

|
||||
|
||||
## 3. Kiến trúc v1
|
||||
|
||||
```
|
||||
[ web (Next.js) ] ──HTTP──> [ ai-service (FastAPI) ] ──> Qdrant (chunk + vector)
|
||||
│ └─> Postgres (hội thoại + trace)
|
||||
└──> provider cấu hình (không bắt buộc Bedrock)
|
||||
|
||||
[ ingestion CLI ] (offline, chạy tay) ──> Qdrant
|
||||
```
|
||||
|
||||
Luồng trả lời, chế độ A (biết tên thuốc — chiếm phần lớn câu hỏi):
|
||||
|
||||
```
|
||||
câu hỏi
|
||||
→ resolve thực thể (khớp chính xác dài nhất trên bảng tên+alias) → drug_id
|
||||
→ phân loại ý định → section_key (+ population nếu là câu hỏi liều)
|
||||
→ LẤY TẤT CẢ chunk của (drug_id, section_key) từ Qdrant bằng FILTER, không phải bằng vector
|
||||
→ ghép lại thành section đầy đủ
|
||||
→ nếu section có attachment quarantine → kèm ảnh crop, và cấm mô hình đọc số từ đó
|
||||
→ LLM soạn câu trả lời, bắt buộc trích: tên thuốc + tên mục + số trang IN
|
||||
```
|
||||
|
||||
Luồng chế độ B (biết khái niệm, không biết thuốc — "thuốc nào trị tăng huyết áp"):
|
||||
|
||||
```
|
||||
câu hỏi → embedding → vector search CHỈ trên section_key ∈ {chi_dinh, duoc_ly}
|
||||
→ gom theo drug_id → trả DANH SÁCH thuốc ứng viên, không trả một thuốc
|
||||
→ người dùng chọn → quay về chế độ A
|
||||
```
|
||||
|
||||
Lý do chế độ B trả danh sách chứ không trả một thuốc: `chi_dinh` là field có
|
||||
độ giống chéo cao nhất (median 0,408, 27,5% số thuốc có hàng xóm > 0,5). Với
|
||||
nhóm PPI thì omeprazol và pantoprazol trùng chỉ định là **đúng y học** — trả
|
||||
cả nhóm mới đúng.
|
||||

|
||||
|
||||
## 4. Công việc chi tiết
|
||||
|
||||
Ký hiệu kích thước (ước lượng): **S** ≈ nửa buổi · **M** ≈ 1 buổi · **L** ≈
|
||||
1 ngày · **XL** ≈ 2 ngày.
|
||||
|
||||
### A. `ingestion/embed/` + `ingestion/load/`
|
||||
|
||||
Chunk record candidate là **schema v4**. `text` là văn bản retrieval có thể lặp
|
||||
nhãn ngữ cảnh an toàn; `source_text` là đoạn nguồn liên tục dùng cho kiểm chứng và
|
||||
reassembly. Payload còn có `context_labels`, `source_page_range`,
|
||||
`printed_page_range`; mỗi attachment mang trang vật lý, trang in, `block_id`, `bbox`
|
||||
và crop nếu có. Loader không tự suy luận provenance và từ chối mọi schema khác v4.
|
||||
|
||||
| # | Việc | File | Nghiệm thu | Size |
|
||||
|---|---|---|---|---|
|
||||
| A1 | Cổng embedding (interface) + adapter OpenAI, batch + retry + backoff | `ingestion/embed/ports.py`, `embed/openai_provider.py` | Test với provider giả, không gọi mạng | M |
|
||||
| A2 | Cache embedding ra đĩa theo `chunk_id` + sha256(text) | `embed/cache.py`, `data/processed/embeddings.jsonl` | Chạy lần 2 không gọi lại API; đếm cache-hit = 100% | M |
|
||||
| A3 | `cli embed` | `ingestion/cli.py` | In: số chunk, số token thật, số call, chi phí; ghi file | S |
|
||||
| A4 | Schema collection Qdrant + adapter | `load/qdrant_repo.py` | Tạo collection, index payload cho `drug_id`, `section_key`, `atc_codes`, `chunk_kind` | M |
|
||||
| A5 | `cli load` — upsert idempotent, point id sinh tất định từ `chunk_id` | `ingestion/cli.py`, `load/upsert.py` | Chạy 2 lần → số point không đổi | M |
|
||||
| A6 | **Gắn corpus vào collection**: lưu sha256 của `chunks.jsonl` vào metadata collection | `load/qdrant_repo.py` | Gate: sha256 lệch → `cli load` từ chối chạy, không upsert lẫn lộn hai đời corpus | S |
|
||||
|
||||
**Khối lượng candidate**: 4.105.382 token (đo bằng `cl100k_base`). Đơn giá phải
|
||||
tra bảng giá hiện hành trước khi chạy — không trích từ trí nhớ. Đây là hạng
|
||||
mục phải có phê duyệt riêng dù ước tính nhỏ.
|
||||
|
||||
Hai thiếu hụt từng chặn embedding — trang in và ngữ cảnh đối tượng/đường dùng —
|
||||
đã được xử lý trong schema v4. Chỉ được coi là xong khi audit toàn corpus trên
|
||||
artifact canonical xác nhận range chính xác và mọi chunk continuation giữ đủ
|
||||
nhãn ngữ cảnh.
|
||||
|
||||
### B. Tầng thực thể / alias — **làm sớm nhất, zero-regret**
|
||||
|
||||
| # | Việc | File | Nghiệm thu | Size |
|
||||
|---|---|---|---|---|
|
||||
| B1 | Trích 344 dòng `X - xem Y` từ back index thành bảng alias | `ingestion/validation/back_index.py` (thêm hàm mới, **không** đổi `parse_back_index` đang dùng cho validate) | Đếm ra đúng 344 (đo); test hồi quy | M |
|
||||
| B2 | Gom tên biệt dược từ 492 mục `ten_thuong_mai` | `ingestion/segment/` hoặc module mới `entities/` | Đếm được số alias thu thêm | M |
|
||||
| B3 | Xuất `data/verified/drug_entities.json`: 683 tên chuẩn + alias + 1.043 mã ATC → `drug_id` | mới | Mọi `drug_id` phải tồn tại trong `monographs.jsonl`; 0 alias mồ côi | M |
|
||||
| B4 | Bộ resolve **khớp chính xác dài nhất**, có test cho **19 cái bẫy substring** | `entities/resolver.py` | `HYDROCLOROTHIAZID` không ra `CLOROTHIAZID`; `PSEUDOEPHEDRIN` không ra `EPHEDRIN`; `DESLORATADIN` không ra `LORATADIN`; `HOMATROPIN HYDROBROMID` không ra `ATROPIN` | L |
|
||||
|
||||
### C. `apps/ai-service`
|
||||
|
||||
Cấu trúc theo Clean Architecture (`CLAUDE.md`): domain không import SDK.
|
||||
|
||||
| # | Việc | File | Nghiệm thu | Size |
|
||||
|---|---|---|---|---|
|
||||
| C1 | Khung FastAPI + `/health` + config qua env | `main.py`, `config.py` | `curl /health` | S |
|
||||
| C2 | Cổng (interface): `VectorStore`, `Embedder`, `Chat`, `PageRenderer` | `domain/ports.py` | Domain test chạy không cần dịch vụ sống | M |
|
||||
| C3 | Adapter Qdrant / OpenAI embed / OpenAI chat / PyMuPDF render | `adapters/` | Test tích hợp riêng, đánh dấu `@pytest.mark.integration` | L |
|
||||
| C4 | Hiểu truy vấn: tách thực thể thuốc (B4) + phân loại `section_key` + nhận diện đối tượng | `rag/understand.py` | Bộ test câu hỏi mẫu; ca không resolve được phải trả "không chắc", không đoán | L |
|
||||
| C5 | Chế độ A: lấy theo **filter**, ghép section đầy đủ | `rag/retrieve.py` | Ghép lại đúng text section (so với `monographs.jsonl`) | M |
|
||||
| C6 | Chế độ B: vector search giới hạn `section_key`, gom theo thuốc, trả danh sách | `rag/discover.py` | Trả ≥1 ứng viên cho câu hỏi chỉ định mẫu | M |
|
||||
| C7 | Soạn câu trả lời + trích dẫn bắt buộc + từ chối khi không có căn cứ | `rag/answer.py` | Không có chunk → trả "không tìm thấy trong Dược thư", **không** để LLM tự bịa | L |
|
||||
| C8 | Xử lý block quarantine: trả `attachment` + endpoint `/crop?page=&bbox=` render ảnh | `routers/crop.py` | Crop đúng vùng của `p109_t0` (ACETAZOLAMID, trang vật lý 109) | M |
|
||||
| C9 | Lưu hội thoại + trace vào Postgres | `adapters/pg.py`, migration | Hỏi 1 câu → 1 hàng trace đọc lại được | M |
|
||||
|
||||
### D. `apps/web`
|
||||
|
||||
| # | Việc | Nghiệm thu | Size |
|
||||
|---|---|---|---|
|
||||
| D1 | Bỏ mock, gọi thật `ai-service` (giữ nguyên DTO trong `shared-types`) | Chat trả lời thật | M |
|
||||
| D2 | Mở rộng `Citation`: thêm `printedPage`, `chunkId`, `attachment?` | Type check pass | S |
|
||||
| D3 | Click trích dẫn → nhảy đúng trang PDF (trang **in**, không phải trang vật lý) | Kiểm bằng mắt 5 ca | M |
|
||||
| D4 | Hiện ảnh crop cho block quarantine + nhãn cảnh báo "không trích số từ bảng này" | Kiểm bằng mắt trên 1 ca có bảng liều | M |
|
||||
|
||||
### E. Deploy
|
||||
|
||||
| # | Việc | Nghiệm thu | Size |
|
||||
|---|---|---|---|
|
||||
| E1 | `Dockerfile` cho `ai-service` | Build + chạy local | M |
|
||||
| E2 | `Dockerfile` cho `web` (Next.js standalone) | Build + chạy local | M |
|
||||
| E3 | Bổ sung 2 service vào `docker-compose.yml` | `docker compose up` ra bản chạy đầy đủ local | M |
|
||||
| E4 | Nạp dữ liệu Qdrant: chạy `cli embed` + `cli load` qua port-forward, viết runbook | `docs/runbooks/load-qdrant.md` (thư mục đang rỗng) | M |
|
||||
| E5 | Helm templates: deployment/service/ingress cho 2 app + Qdrant (statefulset + PVC) | `helm template` render sạch | XL |
|
||||
| E6 | `values-dev.yaml` thật + Secret cho OpenAI key (**không commit key**) | Secret tạo bằng tay hoặc sealed-secret | M |
|
||||
| E7 | Gỡ 3 `TODO` trong ArgoCD Application (project, repoURL, destination) | ArgoCD sync xanh | M |
|
||||
| E8 | CI: build + test + push image + bump tag trong values | 1 lần chạy thật xanh | L |
|
||||
|
||||
**Ràng buộc đã ghi trong bộ nhớ dự án**: repo gitops nội bộ
|
||||
(`git.vinmec.tech/ai-team/gitops`) là chỉ-đọc, **không đẩy gì lên đó**.
|
||||
ArgoCD Application trong repo này trỏ về chính repo này.
|
||||
|
||||
### F. Tracing
|
||||
|
||||
Theo GĐ-2 (trace LLM/RAG). Đề xuất **làm theo 2 mức, mức 1 trước**:
|
||||
|
||||
| Mức | Nội dung | Size |
|
||||
|---|---|---|
|
||||
| **1 — bắt buộc** | Mỗi request sinh `trace_id`; ghi Postgres: câu hỏi, thực thể resolve được, `section_key`, danh sách `chunk_id` lấy ra, prompt gửi đi, câu trả lời, token in/out, latency từng bước, có/không dùng block quarantine. Kèm endpoint nội bộ `/traces/{id}` đọc lại | L |
|
||||
| **2 — nếu còn thời gian** | Self-host Langfuse hoặc export OTel sang stack sẵn có của team | XL |
|
||||
|
||||
Nói thẳng: **mức 2 không phải một buổi chiều.** Langfuse bản mới cần thêm
|
||||
Clickhouse + Redis + object storage — đó là một hạng mục triển khai riêng.
|
||||
Mức 1 phục vụ đúng mục đích thật (debug một câu trả lời y khoa sai thì truy
|
||||
ngược được tới chunk và trang nào), và nó là thứ hợp với văn hoá provenance
|
||||
của dự án này.
|
||||
|
||||
### G. Eval + gate
|
||||
|
||||
Tách đôi, không gộp:
|
||||
|
||||
| # | Việc | Nghiệm thu | Size |
|
||||
|---|---|---|---|
|
||||
| G1 | **Eval định tuyến** — sinh tự động từ chính corpus: với mỗi (thuốc, field) tạo truy vấn mẫu, kiểm hệ có trả đúng `drug_id` + `section_key`. Ground truth suy ra từ dữ liệu, **không bịa một câu nào** | Báo cáo % đúng; không đặt mục tiêu giả | L |
|
||||
| G2 | **Tập đối kháng** — các cặp confusable đã đo (PPI, penicilin, digoxin/digitoxin, estriol/estron, contrast media, nitrit/thiosulfat) | Gate `wrong_drug_returned` = **0** | M |
|
||||
| G3 | Truy vấn bằng **tên biệt dược** trên 344 alias | Gate `brand_name_query_unresolved` = 0 | M |
|
||||
| G4 | **Eval nội dung** — cần dược sĩ/bác sĩ chấm | **Không tự làm được.** Xem §8 | — |
|
||||
|
||||

|
||||
|
||||
## 5. Lịch 2 tuần (ước lượng, không phải cam kết)
|
||||
|
||||
Nguyên tắc xếp lịch: **sau mỗi ngày phải luôn có thứ demo được**, để nếu
|
||||
trễ thì trễ ở phần đuôi chứ không phải mất trắng.
|
||||
|
||||
| Ngày | Nội dung | Cuối ngày có gì |
|
||||
|---|---|---|
|
||||
| 1 | Gate chunk v4: seam label/liều, embargo descriptor, provenance, schema fail-closed | Mọi readiness gate bằng 0; artifact canonical + SHA được chốt |
|
||||
| 2 | B1-B4 (thực thể/alias) + smoke A4-A6 bằng vector giả | Gõ "Panadol" ra `paracetamol`; local Qdrant load đủ 15.100 point, idempotent, rồi dọn collection test |
|
||||
| 3 | C1-C3 (khung + cổng + adapter) | `/health`, gọi được Qdrant + OpenAI |
|
||||
| 4 | C4-C5 (hiểu truy vấn + chế độ A) | Hỏi "chống chỉ định metformin" ra đúng section qua HTTP |
|
||||
| 5 | C7 + C9 (soạn câu trả lời + trace mức 1) | Câu trả lời có trích dẫn, có trace đọc lại được |
|
||||
| 6 | D1-D3 (web nối thật) | **Demo đầu tiên end-to-end trên máy local** |
|
||||
| 7 | C6 + C8 + D4 (chế độ B + crop bảng) | Hỏi theo chỉ định ra danh sách; bảng liều hiện ảnh |

|
||||
| 10 | E5-E7 | Chạy trên k3s qua ArgoCD |

| Dự phòng | E8 (CI), F mức 2, vá lỗi | |
|

Embedding thật không được gắn cứng vào “ngày 2”: chỉ chạy sau khi gate ngày 1
|
||||
đã pass và chủ dự án phê duyệt provider, model, phạm vi và chi phí.
|
||||
|
||||

|
||||
sự cố đều ăn thẳng vào phần đuôi (CI, tracing mức 2).

||||
| Gate | Mục tiêu | Đo bằng |

|
||||
| `qdrant_point_count ≠ chunk_count` | 0 | A5 |
|
||||
| `collection_corpus_sha_mismatch` | 0 | A6 |
|
||||
| Độ đúng định tuyến (thuốc, field) | **báo số thật**, không đặt ngưỡng giả | G1 |
|
||||
| p95 latency | **đo rồi báo**, không hứa trước | tracing mức 1 |

||||
|

|
||||
|
||||
## 7. Rủi ro, xếp theo mức độ
|
||||
|
||||
1. **Segmentation đang bị viết lại (Codex, ngay lúc này).** Nếu `assembler/
|
||||
detector/vocab` đổi thì `chunks.jsonl` đổi, và **mọi embedding đã trả
|
||||
tiền phải tính lại**. → Không chạy `cli embed` cho tới khi bản mới qua
|
||||
đủ: 164 test, 18/18 gate, `cli validate` ≥ 96,0%/99,1%, và so sha256
|
||||
output với mốc đã lưu. Mốc: `monographs 84f41d96…`, `chunks 63472db4…`.
|
||||
2. **Helm viết từ trống (E5).** Không có gì để copy trong repo. Đây là hạng
|
||||
mục dễ vỡ tiến độ nhất sau #1.
|
||||
3. **Tracing mức 2 phình ra.** → Chốt cứng: mức 1 là bắt buộc, mức 2 chỉ
|
||||
làm nếu ngày dự phòng còn trống.
|
||||
4. **Một người, 10 ngày, không có slack.** → Thứ tự trong §5 đã xếp sao cho
|
||||
ngày 6 đã có demo; nếu trễ thì trễ ở CI/tracing chứ không mất demo.
|
||||
5. **Chưa có ai chấm nội dung y khoa.** Gate ở §6 chứng minh hệ *lấy đúng
|
||||
mục của đúng thuốc* — **không** chứng minh câu trả lời đúng về y học.
|
||||
|
||||
---
|
||||
|
||||
## 8. Ngoài phạm vi v1 — nói thẳng, không giấu
|
||||
|
||||
- `api-gateway`, `auth-service`, `user-service`, `chat-service` (§1).
|
||||
- **Các chương tổng quát (in tr. 37-98) và phụ lục (in tr. 1497-1528)** vẫn
|
||||
chưa vào corpus. Hỏi "Kê đơn thuốc", "Ngộ độc và thuốc giải độc" sẽ **không
|
||||
ra gì**. Cần nói trước với người dùng thử.
|
||||
- Benchmark chọn embedding model (bge-m3 vs multilingual-e5 vs provider khác).
|
||||
Runtime vẫn provider-agnostic; chưa chọn provider/model cho full corpus và
|
||||
không được gọi dịch vụ có chi phí khi chưa có phê duyệt riêng.
|
||||
- Tái dựng bảng 2D và nomogram — vẫn quarantine, chỉ hiện ảnh.
|
||||
- Đánh giá nội dung y khoa (G4): **bắt buộc có dược sĩ/bác sĩ chấm.** Tôi tự
|
||||
viết câu hỏi rồi tự chấm thì chỉ đo được trí tưởng tượng của mình, không
|
||||
đo được thực tế lâm sàng — đúng loại bằng chứng giả mà `CLAUDE.md` cấm.
|
||||
- Bản Dược thư 2022 (xuất bản lần 3). Bản đang dùng là 2018.
|
||||
- Mobile app.
|
||||
|
||||

|
||||
|
||||
## 9. Số nào đo, số nào đoán
|
||||
|
||||
**Baseline lịch sử đã đo (2026-08-03, không dùng để load/embedding):** toàn bộ
|
||||
bảng §0; 15.076 chunk; 4.072.725 token
|
||||
`cl100k_base`; 683/11.966/8.212.880; recall 96,0% (677/705), precision
|
||||
99,1%; 18/18 gate; 164 test; 167 block quarantine (129 trong phần liều);
|
||||
344 alias `- xem`; 401 cụm cross-reference; 492 mục `ten_thuong_mai`; 1.043
|
||||
mã ATC; 19 tên thuốc là substring của tên khác; bảng cosine chéo giữa các
|
||||
thuốc; schema chunk v2. Các số này đã bị candidate schema v4 ở đầu tài liệu
|
||||
thay thế và chỉ còn giá trị đối chiếu lịch sử.
|
||||
|
||||
**Chưa đo, là phỏng đoán:** mọi ước lượng thời gian ở §4 và §5; chi phí
|
||||
embedding; p95 latency; độ khó thật của E5 (Helm) và F mức 2 (Langfuse);
|
||||
tỷ lệ câu hỏi rơi vào chế độ A so với chế độ B.
|
||||
|
||||
**Chưa biết, chờ người quyết:** GĐ-1, GĐ-2, GĐ-5 ở §2.

# AWS IAM policies for the Bedrock embedding benchmark
|
||||
|
||||
Two policies, deliberately separate, because they have different lifetimes.
|
||||
|
||||
| File | Purpose | Lifetime |
|
||||
|---|---|---|
|
||||
| `bedrock-embedding-invoke.json` | List, describe and invoke **only** `amazon.titan-embed-text-v2:0` and `cohere.embed-v4:0` in `us-east-1` | Attached for as long as the benchmark and the embedding job need to run |
|
||||
| `bedrock-model-access-bootstrap.json` | Turn on model access, including the AWS Marketplace subscription a third-party model needs before its first call | One-time. Attach, enable access, **detach** |
|
||||
|
||||
Splitting them matters: `aws-marketplace:Subscribe` is the right to commit the
|
||||
account to a paid offer. That is not a permission an embedding batch job
|
||||
should carry around after the one moment it was needed.
|
||||
|
||||
## Measured starting state (2026-08-03)
|
||||
|
||||
```
|
||||
aws sts get-caller-identity -> arn:aws:iam::<account>:user/ai-lab-user
|
||||
aws iam list-attached-user-policies -> []
|
||||
aws iam list-user-policies -> []
|
||||
aws iam list-groups-for-user -> AI-Lab-Group
|
||||
aws iam list-attached-group-policies -> AmazonEC2FullAccess, IAMFullAccess,
|
||||
ElasticLoadBalancingFullAccess,
|
||||
AmazonVPCFullAccess
|
||||
aws iam list-group-policies -> []
|
||||
```
|
||||
|
||||
`ai-lab-user` holds no `bedrock:*` permission from any source, which is the
|
||||
whole of the failure. Both of these were observed, not inferred:
|
||||
|
||||
```
|
||||
aws bedrock list-foundation-models --region us-east-1
|
||||
AccessDeniedException ... not authorized to perform: bedrock:ListFoundationModels
|
||||
|
||||
aws bedrock-runtime invoke-model --model-id amazon.titan-embed-text-v2:0 ...
|
||||
AccessDeniedException ... not authorized to perform: bedrock:InvokeModel
|
||||
```
|
||||
|
||||
## Applying them
|
||||
|
||||
```bash
|
||||
aws iam create-policy \
|
||||
--policy-name BedrockEmbeddingInvoke \
|
||||
--policy-document file://infra/aws/iam/bedrock-embedding-invoke.json
|
||||
|
||||
aws iam attach-group-policy \
|
||||
--group-name AI-Lab-Group \
|
||||
--policy-arn arn:aws:iam::<account-id>:policy/BedrockEmbeddingInvoke
|
||||
```
|
||||
|
||||
Same two commands for the bootstrap policy, then `aws iam
|
||||
detach-group-policy` once model access shows as granted.
|
||||
|
||||
## What is documented vs. what is confirmed
|
||||
|
||||
Confirmed by running the commands above: the current permission state, and
|
||||
that both `ListFoundationModels` and `InvokeModel` are denied.
|
||||
|
||||
Taken from AWS documentation and **not yet confirmed against this account**:
|
||||
|
||||
- that the action list in each policy is sufficient — no live call has
|
||||
succeeded yet, so "sufficient" is unproven either way;
|
||||
- that `cohere.embed-v4:0` needs a Marketplace subscription in this account.
|
||||
It is a third-party model, so the bootstrap policy provides for it;
|
||||
- the foundation-model ARN form `arn:aws:bedrock:us-east-1::foundation-model/<id>`
|
||||
(no account number) — this is the form AWS's own denial message returned,
|
||||
so it is corroborated;
|
||||
- whether the account has an SCP or permissions boundary that would still
|
||||
deny Bedrock after these policies are attached. Nothing here can rule that
|
||||
out from inside the account.
|
||||
|
||||
Region is pinned to `us-east-1` to match the configured region. Widening to
|
||||
`arn:aws:bedrock:*::foundation-model/...` is a one-line change if the
|
||||
benchmark moves region, but it should be a deliberate one.

"""Token counting for the chunk stage.

ADR 0004 sized chunks with `len(text) // 4`, describing it honestly as an

estimate. Measured against the real tokenizer on this corpus, that estimate is
|

wrong by about a factor of two for Vietnamese: real/estimate is **1.95 at the

median, 2.50 at p95, 6.0 at worst**, because accented Vietnamese characters

cost multiple byte-pair tokens each where English prose costs about four

characters per token.

The consequence was not academic. Under the estimate the pipeline reported

**0 chunks over the 800-token ceiling**; counted properly, **1,884 of 12,838

(14.7%)** were over it, the largest at 1,645 tokens — twice the ceiling. A
|

reassuring number that was simply false.

tokenizer installed, and so a different embedding model's tokenizer can be

substituted without touching chunk shaping.

Three defaults are chosen rather than inherited:

- `output_dimension` is set explicitly. The documented default is 1536, and a

collection built at one width cannot absorb vectors of another.
|

- `input_type` is derived from the caller's input kind. This is the model
|
||||
whose asymmetry the `ports` contract exists for: corpus records go in as
|
||||
`search_document`, queries as `search_query`.
|
||||
- `truncate` is `NONE`, which makes an over-length input an error instead of a
|
||||
silently shortened one. A dosing section that lost its tail and embedded

anyway is exactly the failure this project's rules are written against.

`embeddingTypes` is left unset so the response keeps the plain float

`embeddingTypes` contains only `binary`.

Titan draws no distinction between a corpus record and a query, so both input
|

kinds produce a byte-identical request. The kind is still recorded on each
|

vector, because "this model ignores it" is a fact worth being able to read
|

back off the data rather than infer.

"""A disk cache so a corpus is never paid for twice.

|

**Why the key is content-addressed.** A vector is a pure function of three
|
||||
things: the model, the input kind, and the exact bytes embedded. Nothing else
|
||||
about the record changes the answer. `docs/v1-delivery-plan.md` §4.A proposed
|
||||
keying on `chunk_id` + sha256; measured against the real corpus that would
|
||||
charge twice for identical text — `chunks.jsonl` holds 15,066 records but only
|
||||
14,869 distinct texts, so 197 records (1.31%) are repeats of a text already
|
||||
embedded. The key here is `(model_id, input_kind, text_sha256)`, which collapses
|
||||
those and, more importantly, cannot silently serve a stale vector after a chunk's
|
||||
text is edited: an edit changes the digest, so it is a miss.
|
||||
|
||||
Traceability is not lost by dropping `chunk_id` from the key. Every cached
|
||||
record carries the same sha256 rule (`ports.text_digest`) that produced it, so a
|
||||
vector is matched back to its chunk by re-digesting that chunk's text. Pairing
|
||||
vectors to chunk records is `load/`'s job, not the cache's.
|
||||
|
||||
**Why the index holds offsets, not vectors.** 15,066 vectors of 1,024 floats do
|
||||
not belong in memory all at once; a list of that many Python floats is tens of
|
||||
kilobytes each. Startup scans the file once to map key to byte offset, and a
|
||||
`get` seeks and parses exactly one line.
|
||||
|
||||
The file is append-only. A key already present is never rewritten, so the file
|
||||
is a log that can be inspected, truncated, or resumed after an interrupted run
|
||||
without a repair step.

**Asymmetric models make the input kind part of the contract.** Cohere embeds

a corpus record and a search query into deliberately different subspaces —

the same string sent as `search_document` and as `search_query` does not come

quietly drops. So `input_kind` is a required argument of `embed()`, not an

optional keyword a caller can forget, and the value used is recorded on every

vector so a mismatch is detectable after the fact.

**Provenance applies to vectors too.** CLAUDE.md requires an extracted unit to

stay traceable to its source; a vector is no different. `model_id`,

`dimensions`, `input_kind` and the sha256 of the exact text embedded are what

`normalized` is deliberately three-valued. Titan is asked to normalize and

"""Reading the chunk artifact, and computing the identity it is loaded under.
|

|
||||
The digest is taken over content rather than over parsed records, so it still
|
||||
changes on a field reordering that leaves every record semantically identical —
|
||||
a normalised, semantic digest would let a regenerated corpus pass the A6 gate
|
||||
while its point payloads no longer match what `chunk/` produces.
|
||||
|
||||
**Line endings are the one thing normalised, and only because not doing it was
|
||||
a bug.** A raw-byte digest makes the same JSONL hash differently after a Windows
|
||||
checkout with CRLF than after a Linux one with LF. The A6 gate would then refuse
|
||||
a load in CI against a corpus that is byte-for-byte the same data, which is a
|
||||
false rejection with a confusing message — the failure mode of a safety gate
|
||||
that cries wolf is that someone turns it off. Each line is digested with its
|
||||
terminator normalised to `\\n`, which costs none of the strictness that matters.
