# Embedding-readiness audit — 2026-08-04

## Verdict

**Technically READY TO EMBED; NOT authorized to call a paid provider or run a
full-corpus embedding job without separate owner approval.**

Workspace audited: `D:\VSF-DUOCTHU`. No work was performed in the OneDrive copy
or `D:\AITT_VSF`; no commit, push, IAM change, Bedrock call or cloud resource was
created.

## 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.
