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.
