The summary is model prose about the document and is contractually
descriptive-only, but it was returned to the browser verbatim with no guard.
Screen it against the insights contracts and let each caller apply its own
policy: the on-demand route replaces the text with a short honest statement
because a user is waiting on it, while the background job persists nothing --
its updateMany is guarded on a null summary, so a stored refusal would stamp
the document permanently with no path to regenerate.
Transcription stays unscreened by construction. It reproduces the user's own
document verbatim; a discharge letter that says to increase a dose is the
prescriber's instruction, and censoring it would delete the user's own record
from their own view. Locale is required on the summary input type and absent
from the transcription input so a caller cannot silently fall back to the
English banks.
P2-1. The list GET now issues a documentContentIndex lookup and unions a
content-token OR branch when a search term is present, so the existing route
test gains the mock + the third OR branch in its where assertion. Fix the
backfill test's findFirst mock signature under strict tsc.
P2-1-T2/T3/T4/T5/T6.
- assist.ts + [id]/suggest: one provider call proposes a { title, kind,
documentDate } filing draft over the stored original or browser-OCR text.
Runs the full extract gauntlet (module → provider → consent → rate-limit →
budget) but writes nothing — never touches the fact rail or status.
- describe.ts + [id]/summary?mode=summary|text: session-only summary or raw
transcribed text. Descriptive only, no diagnosis; persists only the budget
ledger + audit.
- content-index.ts + [id]/index: normalise → tokenise (de-accent, stopword
drop, whole-word) → HMAC-SHA256 under an HKDF-derived subkey → store the
token array plus AES-256-GCM ciphertext of the text. Vision path transcribes
via the provider (consent + budget); text path indexes posted local-OCR text
(no egress). Gated on the existing AI consent — no new per-user toggle.
- crypto.deriveSubkey: HKDF-SHA256 purpose-bound subkey off the active key.
- list search now unions title/filename ILIKE with a GIN-accelerated
whole-word content-token match; DTO gains hasContentIndex.
- usage gains assistAvailable + contentIndex { enabled, indexedCount,
totalCount }; detail gains hasContentIndex.
