CI's diff-hygiene gate rejects a trailing blank line at EOF; the local
check:diff run happened before the first commit existed, so it checked the
previous range and missed it.
Promote the ingest script into an auditable corpus pipeline. Each sample now
records consent (version + timestamp), source kind and raw-input digest, both
hashes, the derivation pipeline, review status, split, and lifecycle state, with
the caller's path never written down.
Withdrawal is a new `--revoke <contribution-id> --reason` operation: it deletes
the derived image and any raw pre-derivation copy, then appends a tombstone that
addresses each removed artifact by contribution id and digest while dropping
labels, subject key, and paths. History is append-only, so the original sample
record survives the withdrawal it documents.
Illegal moves are refused instead of silently applied: revoked -> active,
revoking an unknown or already-revoked contribution, an unknown state, a
duplicate contribution id, and a second label set for the same derived image.
The duplicate guard runs before any byte is written, so a refused ingest cannot
strand an image in the active dataset.
Tests written first and watched fail (tests/corpus-manifest.test.py): provenance,
tombstone + byte removal, active-record filtering, and the transition guards.
The transition helper itself passed on first write and is reported as a
hold-out check rather than a RED cycle. Wired into the quality workflow and
check:syntax; contract documented in docs/CORPUS-MANIFEST.md.
No browser surface changed, so record_release_demo.mjs is untouched and claims
nothing new: the nearest honest visible effect is the withdrawn-receipt
tombstone already recorded for #24.
A leftover checkout answering on 127.0.0.1:4173 satisfied the readiness probe,
so every acceptance flow and the recorded demo described another tree while the
build reported green. The builder now fails closed if the port already has a
listener, re-checks the spawned server after readiness, and verifies the served
app.js and src/domain.js bytes match the clone under test before the first gate.
Verified against a real stale tree: the occupied-port guard aborts, the
foreign-bytes guard aborts, and the matching tree still passes.
The import screen already states what it restored, and the migration notice
restated the same count, so the on-screen notice read as two stacked sentences
saying one thing. The notice now only describes the upgrade, and a unit test
fails if it starts restating the restored count again.
A backup is the person's own record and has to keep working as the AI fields evolve.
- Export stamps schema version 2 and carries the confirmed logs plus the training
contribution receipts, including withdrawn tombstones; both are written through an
allowlist so unknown keys and credentials never leave the device.
- Import accepts version 1 and 2. A version 1 file is upgraded, the notice names the
version it came from, and entries that predate provenance stay null instead of being
given a source they never recorded.
- A file from a newer Timmy is refused with an update instruction, malformed, oversized
and over-limit files fail closed, and a refused import leaves the ledger unchanged.
- A log saved from a confirmed or corrected AI suggestion records its provenance
(source, suggested visible fields, model, confirmedAt) and the entry sheet states it.
- Service worker shell cache v5 -> v6 so installed clients actually receive the change.
Evidence: tests/portability.test.js (7 unit cases), tests/portability.acceptance.mjs
(real browser: v1 upgrade, future refusal with unchanged ledger, provenance recorded,
export v2, round trip), release demo scenes with on-camera caption proof, and the
release builder gate portable_backup_restore.
Refs #35
The opt-in row and its tombstone rendered as one run-on line ('Type 4 ·
brownReceipt contrib-…', 'Withdrawn Oct 21, 12:09 PMraw image, …') because
nothing styled .contribution-row: the label and the receipt/artifact line
shared a line and the Withdraw control butted against the text.
Split label and detail into their own lines, right-align the row action,
mute withdrawn tombstones, and keep long receipt ids wrapping inside the
card. Verified on a 390px viewport: queued, withdrawn, and offer rows are
separately legible with no horizontal overflow.
A journal save now records no training contribution. A contribution is a second
consent: the privacy page states consent version training-consent-v1 and the
receipt (contribution id, included fields, never-included fields) before the
confirm control is enabled, the receipt is queued on this device only and copies
no photo bytes, note text, or symptom answers, and withdrawal keeps a tombstone
naming every derived artifact by contribution id. Delete-all clears the receipts
with the ledger.
Closes#24
The demo injected its caption CSS with page.addStyleTag(), which writes into the current document
only. The first page.reload() in the recording stripped that stylesheet, so every later caption
rendered as unstyled body text clipped at the bottom of the frame and every touch indicator was
invisible, while the caption receipt still listed each string and the release gate accepted it.
- caption and touch nodes now carry inline styles, which no reload can remove
- caption() proves each caption is a fixed bar at the top of the viewport, on top of what is
beneath it, fully inside the frame, and that the caption band pixels change; the recording fails
rather than shipping a caption nobody can read
- the receipt records per-caption evidence and build_release.py requires every required caption,
including the release delta, to be pixel-verified
- the demo photo is a legible synthetic test card instead of a 1x1 white pixel that rendered on
camera as an empty box
- tests assert the inline styling and the pixel gate
A confirmed log and the image attached to it are separate things the
person owns. The journal now reports a saved photo as a label instead of
a thumbnail, reveals the image only on explicit request, removes the
photo without touching any confirmed field, and deletes a log through a
separate two-step decision that takes its photo with it. Delete-all is
regression tested to remove the ledger and every stored photo together.
- src/photo-lifecycle.js: presence decided by stored image bytes;
withoutPhoto/withoutEntry return new lists and never mutate the ledger
- app.js: journal rows expose Open-entry controls; entry sheet states
presence, offers explicit reveal, remove-photo-keeps-log, and a
two-step log delete; privacy copy names photo removal and delete-all
- tests: 6 unit cases + browser acceptance (presence, no default
thumbnail, explicit reveal, remove keeps log, two-step delete,
delete-all leaves no image bytes, Escape dismiss, 44px targets)
- record_release_demo.mjs: on-camera photo lifecycle scenes driven by a
synthetic 1x1 PNG, with delete-all actually performed and asserted;
build_release gates the new captions
- CI/release/syntax gates include the new suite
Closes#36
Chat now has to show its work. Every answer that states a count, a date, or a
visible form cites the confirmed records behind it, and following a citation
opens exactly that log. Questions the journal cannot answer (food safety,
medicine, what a symptom means) get boundary copy with no borrowed evidence,
and a sparse window refuses to describe a trend instead of naming one.
The Hermes path is held to the same rule: the server gives each ledger record a
positional ref, the prompt requires inline [entry:L<n>] citations, and the
browser resolves them against the ledger it sent. A ref that matches no record
is stripped and the answer is labelled unverified rather than rendered as a
source, so an invented citation cannot look like evidence.
The release recording now exercises the grounded local answer, its citation
sheet, the refusal, and a Hermes reply whose refs resolve, each asserted in the
browser with fictional logs.
Deterministic escalation only fired on a narrow set of literal phrases, so real reports
like "there is blood when I wipe" or "I have tarry stools" reached the chat provider
without the fixed medical guidance. Expanding the suite found 18 of 18 checked clinical
phrasings missing.
- domain: cover bleeding reported by wiping/toilet paper/anatomy/mixed-in phrasing,
black-tarry-dark-red stool, reported temperature and high temperature, abdominal-scoped
severe pain in every natural word order, and past-tense/slang inability to pass gas.
Near-miss wording that must stay quiet (paper cut, blood pressure, black beans, dark red
wine, a normal temperature, knee or back pain, passed gas, no gas in the car) is pinned.
- domain: a symptom reported in any truthy shape (1, "yes", "true") now counts as reported.
Reading only the literal boolean `true` silently cleared a symptom, which is the one
direction this boundary may never fail in.
- hermes-agent-service: the gateway ledger sanitizer used the same strict check, so a
browser-supplied ledger entry could have its symptom cleared before the escalation check.
- tests/escalation-regression.test.js: per-flag positive and negative language coverage,
model output can neither set nor clear a symptom/urgency/discomfort/note, and the
escalation copy is byte-identical for every flag and under a missing, throwing, or
malicious provider. Registered in the default unit gate.
- scripts/record_release_demo.mjs: the recording now types the new bleeding and tarry
phrasing, and seeds a fictional ledger whose note says "stool was tarry yesterday", then
asserts in the browser that exactly one new Timmy bubble carries the app's own copy and
that the turn never reaches Hermes. Three new captions are required release gates.
Boundary unchanged: no new inference, no diagnosis, no image claim. Escalation only ever
gets broader on user-reported symptoms.
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.
Two defects found inspecting the first demonstration of this release:
- A caption stayed on screen until the next one replaced it, so the
delete-data caption was still displayed over the home view after the
navigation. Captions now fade and remove at the end of their stated
duration, so no caption outlives the screen it describes.
- The contact sheet used a fixed 1/2 fps, so a 88s demo only showed its
first 24s in the review sheet. The sheet rate is now derived from the
probed duration and a missing sheet fails the build.
A documentation-only release previously recorded a demo captioned
'FEATURE DEMO', which implied a shipped feature that did not exist. The
demo now renders the builder-supplied release delta as its second
caption, and the builder refuses to publish unless the demo's own
machine-readable caption receipt proves that statement reached the
screen and every required feature caption did too.
The recording also shows the byte-bearing controls the photo data-flow
threat model governs (consent-gated upload, portable export, delete all
local data) using the app's real selectors, so a docs-only release
demonstrates the nearest real user-visible effect instead of inventing
UI.
- docs/PHOTO-DATAFLOW-THREAT-MODEL.md: browser, API ingress, model worker,
transient buffers, training opt-in store, logs, exports, and deletion,
with trust boundaries and a numbered threat register
- every named abuse case (replay, oversized input, metadata leakage,
poisoning, unauthorized training, operator access) carries a mitigation,
an owner, a tracked follow-up ticket, and the artifact that will prove it
- tests/threat-model.test.js enforces diagram coverage, owner/follow-up
presence against ROADMAP ticket numbers, and the non-diagnostic boundary
with synthetic-only fixtures
- link the model from the accepted product decision record
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
