Refs #223. A due Vorsorge item could only be done, deleted or ignored;
Telegram's postpone moved the date with no trace. Both decisions are
first-class now, and both are honest:
- POST /{id}/skip (no body): the interval restarts from the skip instant
through the recurrence engine, lastSkippedAt is stamped, skipCount
increments, any snooze clears. lastSatisfiedAt is NEVER touched — done
and skipped stay distinguishable forever, enforced in the primitive and
pinned by tests.
- POST /{id}/snooze ({until: YYYY-MM-DD}): the server resolves the day to
the notifyHour in the profile timezone and moves snoozedUntil and
nextDueAt to the same instant, so every due-state consumer follows
without knowing snooze exists. At least tomorrow, at most five years.
- GET /{id}/history: the new append-only completion ledger
(MeasurementReminderEvent), one row per satisfy from every engine path
and per skip, onTime derived at write time against the due instant that
was current when the event landed.
Two anchor fixes close the backdated-event gaps: the auto-resolve floor is
now the later of last satisfy and last skip (an old reading synced late no
longer resolves the cycle the user just skipped), and a backdated real
result re-anchors the next due at the later of its own instant and the
skip decision.
Screenings stay skippable and snoozable — the satisfy-side 409 guards
claimed fulfilment; a skip claims the opposite. Appointment reminders 404
on all three routes, in the lookup, like every by-id sibling. /checkups
gains the postpone sheet (quick chips, date field, the skip zone with its
own confirm) in both view branches, with muted meta lines and no card
colour change. The MCP preventive-care tool carries the resolved fields;
the OpenAPI contract publishes all three paths and the widened DTO.
get_preventive_care passed a reminder's label and location — the user's
own free text — unfenced beside a fenced sibling, and get_lab_history
shipped the document-derived canonical analyte raw while sanitizing the
valueText next to it. Both are the marker-forging class the fence
doctrine exists for: fence label and location like the appointment
reason, scrub and sanitize the analyte like the default labs path.
Add get_visits, a bounded read of past visits (default the last 12
months, optional practitioner-name filter) returning date, status,
kind, practitioner, specialty, the visit's own reason and outcome, and
the linked condition labels, newest first. Absence is explicit: an
account that has never recorded a visit reads { present: false }, never
{ present: true, visits: [] }.
Fold upcoming appointments into get_preventive_care as their own named
field rather than minting a second due-list tool, so a question about
what is coming up gets one answer. The Vorsorge arm stays free of
ENCOUNTER-origin reminders; the appointments are read from Encounter
directly. Reason and outcome ride the USER_TEXT wrapping, and every row
is scoped to the caller by construction.
Nine visit routes and five practitioner routes, all classified under the
existing profile domain and each reviewed into the frozen sharing
literal with the sentence that argues for it. An address book of a
person's own doctors is record content, not account configuration: it
names no credential, no integration and no notification channel, which
is the fence that classification turns on. The eight sharing domains are
unchanged. Link and unlink stay bare, matching document link and unlink,
and the pair is revisited as one decision later.
Nothing is a required field. A visit saves with a date and nothing else.
Every id a body may carry is re-narrowed to the caller before anything
is written, and an unknown link id never blocks a save.
A booked visit mints exactly one reminder on the existing engine with
the new origin, and the appointment half is the part worth reading
twice. Both cadence columns stay null, which is the schema's one-shot,
so the first due instant is stamped directly and the never-nag property
is structural rather than guarded: after it fires, the cadence helper
has no occurrence to return. Rescheduling re-anchors that row and never
mints a second, which the tests assert by counting rows rather than by
checking the date moved.
Filing a visit as done closes the checkup it was filed against, on the
transition rather than on every later edit. Writing the test first found
that: satisfying is forward-only, so re-saving a completed visit was
pushing the checkup's next due date out again as if the person had been
a second time.
An appointment must appear on no preventive-care surface, and that is
four separate reads, one of them in the assistant tooling. Each carries
the exclusion, a guard proves all four by source text with a non-zero
match count, and the reminder mapper refuses such a row outright — so a
read site that loses its filter fails loudly instead of showing an
appointment as a checkup. The published origin enum is untouched.
The MCP due-list answered "is this checkup overdue" by comparing the two
instants, so a checkup booked for nine in the morning read overdue from ten
past. The screens read the same reminder as "today" until midnight. One
reminder, two verdicts, and the model reading the tool result repeated the
one nobody could see.
Same counting as the screens and the briefing payload now, on the account's
own clock rather than the server's. A checkup stays due for the whole of the
date it belongs to, and is overdue from the date after.
The admin panel offered a toggle for the Health-Score explainer and
described it as the ? next to the delta line. That ? had already been
taken off the insights surface a release earlier, and the caption that
replaced it went away entirely when the health score was replaced by
the reference composite. Since then an operator could turn the switch
off, get a saved confirmation, and change absolutely nothing.
The toggle, its wording in all six languages, its place in the flag
matrix the app and the iOS client both read, and its column on
app_settings are all gone. Nothing is left to promise a control that
does not exist.
A guard goes in with it: every remaining assistant sub-flag has to be
read by some surface, and the panel and the plumbing that carry all of
them by construction do not count as proof.
A sync failure the classifier bucketed as `transient` had no exit. The park
test read `kind === "persistent"` and the persistent streak anchor was only
ever stamped by a persistent failure, so a streak could run for a thousand
attempts with the persistent counter at zero, the state frozen at
`error_transient`, and no ladder it could climb. `transient` is a hypothesis
about retryability, and the classifier defaults every timeout, 429, 5xx and
unrecognised response to it precisely because the wire cannot tell a reboot
from a permanent break. That default is right for one attempt and wrong for a
thousand: an unbroken streak retried hourly for a full day has refuted it by
experiment. Record it as `persistent` from there, which feeds the park ladder
that already exists — 48 h of unbroken failure end to end before an
integration stops attempting.
The counters could not accumulate anyway. `IntegrationStatus` is keyed
(user, integration) while Withings runs four legs on four crons and WHOOP four
resources on four more, and a success cleared the error, every bucket, the
streak anchor and the state whatever leg had recorded them. The ECG tick at
:41 wiped what the sleep tick recorded at :15 — including a reauth park — so
the strike ladder was reset several times an hour and the card painted a green
"connected · 12 minutes ago" over a data class that had stopped arriving. A
success now clears only what it is entitled to clear.
Two columns carry it: `failing_since_at` dates the streak, `failing_leg` names
its owner. The migration backfills the anchor for rows already in an error
state so a connection broken for weeks escalates on its next attempt rather
than restarting its clock.
Mood has been a first-class module here for a long time, with entries,
structured tags, rated factors and notes. The bridge to the external moodLog
service had nothing left to add, and its Settings card was withdrawn in
a56e6fe61 on the promise of a dedicated removal. This delivers it.
Removed: the hourly `moodlog-sync` queue, cron and handler binding; the
inbound webhook and its shared-secret handling; the reverse push and its four
call sites; the pull-sync module; the per-user credential routes and the
instance-wide toggle; the entry on the `/api/integrations/status` envelope,
the `IntegrationKey` union, the cadence map and the display-name table; the
boot-time secret rotation pass; 22 message keys per locale.
Migration 0271 drops the five `users` credential columns and
`app_settings.mood_log_global`, clears the ledger row for the provider, and
deletes the retired pg-boss schedule so no cron keeps enqueuing work no
handler drains.
Mood data is untouched. `mood_entries` is not named anywhere in the migration
and cannot be reached from it: the dropped columns carry no index, constraint
or foreign key, and `mood_entries.user_id` references `users(id)`, not any of
them. Rows the bridge imported keep `source = 'MOODLOG'`, and every read path
- list filter, source badge, exports, backups - still resolves that value.
`src/lib/validations/moodlog.ts` held the native mood-entry schemas alongside
the bridge's own; it is now `validations/mood.ts` and carries only the former.
The load-bearing one is the panel-coverage test: render the panel with an
envelope carrying every integration key and require each configured one to
surface as a card or as a fallback row. Drop the fallback row and it goes red,
which is the whole point — the previous shape of this bug was a provider on
the wire that no screen rendered, and no card-shaped test could have caught it.
Alongside it: the ladder table with the month-silent fixture that resolves to
stalled, the 24-hour and 7-day boundaries asserted against literals rather than
the constants they check, the per-metric stale flag firing only under a healthy
provider, and a structural guard that the verdict-to-pill mapping is defined in
exactly one module.
The card suites migrate with the semantics: a transient failure now expects the
warning pill everywhere, and the Apple Health suite trades its bespoke badge
states for pill assertions. The e2e mocks gain the verdict shape, the
nightscout entry, and an assertion that the card-less row is on the page.
Wrist temperature, cardio recovery, sleep score, breathing
disturbances, strain/load, and the rest of the v1.10/v1.18.1
metric-status-registry ids were already resolvable through
compare_metric / get_metric_baseline / detect_changepoints (an exact
registry-id or display-name match), but sat off the Coach snapshot
inventory entirely — so list_metrics, the measurements-inventory
resource, and search never advertised them. A discover-before-fetch
assistant, which the server's own instructions direct, could never
learn they existed.
Adds a fixed, reviewed allowlist (MCP_METRIC_STATUS_DISCOVERY) plus a
metricStatusDiscoveryRows() presence probe, mirroring the existing
MCP_CLINICAL_SIGNALS pattern: one grouped presence query, appended as
supplement rows to list_metrics and the inventory resource, and merged
into the same probe search already runs for the v1.25 clinical
signals. fetch(id) now hydrates these ids via the baseline read the
same way it already does for clinical signals.
Adds MCP coverage for ECG recording metadata (recorded time, duration,
sampling rate, sample count, average heart rate, lead, and the
device's own rhythm classification) — previously unreachable because
ECG has no MeasurementType and so cannot appear in list_metrics or the
metric resource templates.
get_ecg_recordings mirrors GET /api/insights/ecg exactly, down to the
select clause: waveformEncrypted is never selected, so a decrypt can
never happen on this path. Non-diagnostic framing carries through:
classificationSource is a fixed "device" literal, and the description
states plainly that HealthLog never re-classifies. Gated on both the
insights module and the insightStatus assistant-surface flag, mirroring
the route's own two-layer gate.
Adds MCP coverage for the intraday pulse / "shape of the day" —
previously unreachable, since get_metric_series only serves daily
aggregates and cannot answer "what happened this afternoon?" or "was I
tense during the meeting?".
get_intraday_pulse is a thin wrapper over loadIntradayPulse, returning
the same DTO GET /api/insights/pulse/intraday serves verbatim: the
10-minute mean shape (dense-90d, hourly-grain fallback outside that
window per the resolution field), the resting baseline, and the
cautious elevated-at-rest tension window when every confidence gate
holds. Gated on the insights module; never fabricates a reading for a
day with no data.
Adds MCP coverage for the NutrientIntakeDay pipeline (water, caffeine,
24 micronutrients) — previously fully unreachable over MCP, and
search("water") / search("vitamin") silently miscollided or read as
honest absence even for a daily logger.
get_nutrients is a thin facade over the same two reads GET
/api/nutrients and GET /api/nutrients/daily run: the tz-anchored
day-key math, the sum-across-sources fold, and the sex-aware EFSA
reference resolution. Gated on the opt-in nutrients module, mirroring
both backing routes. Discoverable via search (a grouped presence
probe) and fetch, plus a healthlog://nutrient/{code} resource template
with completion + listing scoped to the user's own logged codes.
Bring the new physical clinical signals onto the MCP read surface through
the existing rollup-backed reads. Grip strength, pain (0-10 NRS), waist
circumference, and waist-to-height ratio now resolve in get_metric_baseline,
compare_metric, and detect_changepoints, are discoverable through search
(present-only), and hydrate through fetch (metric:<KEY>).
These signals sit off the Coach snapshot by design, so the MCP layer owns
an explicit exposure allowlist and consumes the signal registry only for
grounding (backing measurement type, unit, population band). The PHQ-9 /
GAD-7 mental-health screeners and the environmental signals are absent from
the allowlist, so they never resolve through any read tool. The longevity
lab panel is already reachable through get_labs and the lab resource
template; no change needed there.
Add three grounded read tools, each a thin façade over an existing
server-authoritative engine (no new analytics, userId from the session):
- get_medication_schedule: next-due / overdue per active medication via
the canonical recurrence engine (computeDisplayDue), with as-needed
flagged and no scheduled due time.
- get_integration_status: per-provider sync health (connected, last sync,
reauth-required/failing) from the integration-status ledger, so a user
can see why their data is stale. No secrets or tokens.
- get_preventive_care: the user's already-configured Vorsorge reminders
with their persisted next-due dates and an overdue flag; it surfaces
configured reminders only and invents no screening logic.
Each declares an output schema, read-only annotations, and {present:false}
on absence. Page the search tool across the full assembled result set
(the prior 200-row scan made later items unreachable even through the
cursor) and give each result a per-item deep link where an id exists.
Bridge the five already-built, grounded Coach retrieval tools the
inventory already advertised but the wire was missing — closing the
advertise-but-missing self-inconsistency — each a thin wrapper over the
existing read with the same gates and present:false contract. Add a
multi-metric fan-out that loops the single-metric read, and a per-analyte
lab-history mode on the labs read. Declare a structured output schema on
every remaining tool so structured content validates for both a miss and
a hit. Page the large reads (search, lab history, multi-metric) behind an
opaque cursor. Return plain-text, citation-ready summaries from fetch
with per-item deep links instead of a JSON dump.
Expose four read-only relational tools and one prompt over the MCP wire,
each a thin re-export of an existing server-authoritative engine — no new
statistics, no new business logic:
- get_correlation: the FDR-controlled, lag-aware association between two
named metrics, selected out of the existing correlation discovery the
Coach and the insight route already run. Descriptive, never causal.
- compare_metric: two metrics over the same trailing window, or one metric
across two trailing windows, computed over the WMY rollup readers with a
delta only when both sides share a unit.
- get_metric_baseline: where today's reading sits against the user's own
usual range (median ± robust deviation) plus the strongest lagged driver,
reusing the metric-page baseline builder. Honest-null below the learning
floor — never a fabricated range.
- detect_changepoints: level shifts over the rollup tier via a small in-repo
CUSUM binary segmentation with a high firing bar.
- doctor_visit_summary prompt: a structured, grounded visit-prep summary
assembled from the doctor-report data path so the numbers match the
exported PDF, with the grounding framing injected once — data and context
only, no diagnosis or verdict.
Every tool returns values, units, reference bands and provenance, declares
read-only / non-destructive / closed-world annotations plus an output schema,
and reports { present: false } for absence. All reads stay session-narrowed
and read-only; the existing security posture is unchanged.
- Add the `search` + `fetch` retrieval pair with the exact ChatGPT wire
shapes (`{id,title,url}[]` and `{id,title,text,url,metadata}`), backed by
the same server-authoritative reads and returning real deep-link URLs into
the web app for citations. Without these the server is invisible in
default-mode ChatGPT.
- Annotate every read tool `readOnlyHint`/`destructiveHint:false`/
`openWorldHint:false`; structured tools also declare an `outputSchema` and
return `structuredContent`. Omitting the hints is a validation error in the
connectors.
- Reject a cross-origin browser request to `/mcp` with 403 (DNS-rebinding
defense) and point the 401 `WWW-Authenticate` at the resource metadata.
Introduce a read-only Model Context Protocol surface built on the official
@modelcontextprotocol/sdk so a user can query their own HealthLog data from an
MCP-capable assistant over local stdio with a pasted, scoped Bearer token — no
extra infrastructure.
The tool and resource layer in src/lib/mcp is transport-agnostic: five read
tools — list_metrics, get_metric_series, get_medication_compliance, get_labs,
get_correlations — each a thin wrapper over the existing server-authoritative
retrieval paths, returning structured values, units, reference bands, and
provenance with an explicit { present: false } for absence and no prose
verdicts. Two resources expose the user's profile (data-minimised) and
medication list. A stdio entrypoint (src/cli/mcp-stdio.ts, pnpm mcp:stdio)
resolves the token through the shared Bearer path and binds the session to
<user>:<token>; with no token it refuses to start.
Read-only and admin-unreachable by construction: only read tools are
registered, and requireAdmin stays cookie-only so the Bearer/MCP wire can never
elevate. Covered by unit tests for every tool and resource, the auth/scope
model, and the cookie-only admin boundary. The server ships in the existing
container; docker compose up is unchanged.
