The home insight card now reports the confirmed-log count and form
groupings for a window, every line names the exact confirmed records it
was built from, and following a citation opens those records. A window
below the minimum states that it is too sparse instead of describing a
trend, and a window with both firm and loose logs says it is mixed rather
than picking a winner. No line explains a cause, rules on food, or offers
a health verdict.
- src/summary.js: window filtering, insufficient-data guard, per-form
lines, mixed-pattern line, boundary copy, record citations
- app.js: explainable home card plus a pattern-source sheet listing the
cited records
- tests/summary.test.js, tests/pattern-summary.acceptance.mjs: unit and
real-browser coverage, gated in CI and the release builder
- scripts/record_release_demo.mjs: fictional multi-day sample logs,
citation follow-through, and the sparse-window refusal on camera
A worker that answers /v1/models has not necessarily loaded its weights, so the app
was offering an AI control that could only fail after the upload. Readiness now
passes only once the pinned model is loaded, and the not-loaded state reaches manual
Bristol entry in one tap. Verified against the real pinned llama.cpp build: it serves
503 while loading and the gate reports the distinct not-loaded state.
Adds the reproducible container recipe (digest-pinned bases, pinned llama.cpp commit,
hash-verified read-only weights, unprivileged, loopback-only publish), one shared
post-load readiness gate used by the host bootstrap and the image healthcheck, and a
target-GPU benchmark that refuses to write a receipt it did not measure.
Refs #15
The blank-first ordering let one blank field short-circuit the whole reply, so a
response carrying an impossible value came back as `unusable_visual_fields`:
the user was told the photo was unreadable when the model had in fact returned
something Timmy must never apply.
Blank fields still abstain and still prefill nothing. A filled-in field is a
claim, and a claim outside the contract now fails closed even when the other
field came back blank.
The corpus earns its label too. `out-of-range-fields` drops from confidence 1.4
to 0.9 so the case reaches the field-range check instead of dying at the
confidence gate, and a new `blank-plus-out-of-range` case covers the class the
old ordering let through. The release demo replays that case on camera and the
fail-closed 503 budget moves from one to two, so the scene cannot be dropped
silently.
Closes#73
The worker contract was only proven by one happy-path fixture and a handful of
inline assertions, so nothing continuously checked that a reply Timmy cannot use
is refused instead of guessed at.
Corpus: a CC0 synthetic corpus (stool, non-stool, blur, glare, empty bowl,
malformed response) generated deterministically by scripts/build_vision_corpus.py.
Every fixture records its sha256, provenance, licence, case class, the provider
reply it replays, and the outcome that reply must produce. loadVisionCorpus
refuses a fixture whose bytes no longer match the manifest, so the corpus cannot
be edited into a different test. No real medical imagery, camera, or third-party
content is involved.
Contract fixes the corpus exposed:
- A schema-valid reply with a null form and colour is now an abstention
(abstainedFor: unusable_visual_fields) instead of a hard provider failure. The
declared response schema permits those nulls, so treating the reply as an error
was wrong; it now abstains calmly and still prefill nothing.
- Fail-closed replies carry a machine-readable code (invalid_json, invalid_fields)
instead of prose matching, and visionFailureResponse() maps them to plain,
user-safe copy with no provider text, image bytes, or credentials echoed. A
running server now returns that copy for unparsable and out-of-range replies.
Evidence: unit corpus contract and hash integrity, corpus-wide conformance
through the real analysis path, the same corpus through a running server.mjs with
a stub worker (200 abstain vs 503 fail-closed, no leaked bytes), and a real
browser acceptance run for the refusal UI. The release demo replays three corpus
cases through the real code path so the video shows the status the server would
actually send, with the on-camera caption gated by the release builder.
Field finding #67: a hard/lumpy (Bristol 1-2) entry now asks a short follow-up
before saving — difficult to pass, soreness, visible red blood, truly
black/sticky/tarry versus dark brown, and dehydration. Every answer is
user-reported and starts unanswered; nothing is inferred from the photo, and
answering "dark brown" never silently escalates as black stool.
A confirmed red-flag answer writes the same symptom flag manual logging already
uses, so the existing deterministic escalation is the only escalation path.
Mild reports get concise non-diagnostic self-care that states the photo cannot
rule out bleeding, and it is withdrawn whenever a red flag is confirmed.
- src/followup.js: pure follow-up contract (9 unit tests, tests/followup.test.js)
- app.js + styles.css: follow-up block on the safety step for Type 1-2 entries only
- tests/followup.acceptance.mjs: browser acceptance incl. that the AI suggestion
surface still contains no symptom wording
- CI + release builder gates: npm run test:followup, syntax checks, manifest gate
- scripts/record_release_demo.mjs: records the real follow-up, mild guidance, and
the black/tarry alert handoff with synthetic data
Suggested, confirmed, and corrected AI states are now distinct in the log
sheet, and correcting a suggested value clears the AI-confirmed state while
keeping every user-entered field. Screen-reader copy states the AI confidence
and who is in control.
- src/suggestion.js: provenance state machine (pending/confirmed/corrected/manual)
- app.js: renders provenance on the scan result and log steps, tracks corrections
- tests/suggestion.test.js: unit coverage for the state machine and a11y copy
- tests/provisional-suggestion.acceptance.mjs: browser acceptance + screenshots
- record_release_demo.mjs: demo now reviews, confirms, and corrects the suggestion
- CI, release builder, and release notes gate the new contract
Logging must never depend on AI availability, and an unsaved entry must not
disappear when the user navigates away mid-log.
- add src/vision-readiness.js so the photo flow consumes one readiness contract
- when the worker is offline/disabled/unknown, offer no AI action and no
analysis-consent prompt, and keep manual Bristol entry one action away
- add src/draft.js and make the draft own the photo so a chosen photo and
entered context survive a recoverable close or navigation, with a visible
kept-draft summary and an explicit start over
- drafts stay in session memory only: a photo awaiting consent is never
persisted, and reload starts clean
- service worker now refuses to cache image bodies in addition to analysis
requests and no-store responses
- tests: 2 new unit files, 3 service-worker privacy assertions (1 hold-out),
1 browser acceptance file, release-demo and CI/package assertions
- release demo now visibly replays the vision-offline pass and the retained
draft with synthetic data and an in-script assertion
