A response parsed against its own registered schema disagreed in thirteen
operations. Where the handler was right, the schema now says so; where the
handler had drifted from its siblings, it follows them.
Schema:
- measurements list and detail declare aggregationProvenance
- series-batch and sleep night stages are partial records: only the
requested types and the recorded stages are present
- medications declare deliveryForm, the injection-site fields, externalId,
externalSource, the low-stock bookkeeping, schedules[].doseWindows and
nextDueScheduleId on the list
- notification prefs declare coach.nudgeAiComposed and measurementReminder
- mood insights correlations declare suppressed
- record settings profile.unitPreference is nullable, as stored
- insights/comprehensive describes the computed overview it returns rather
than the model digest fields it never sends
Handler:
- GET /api/mood-entries/{id} shares the list projection and now carries
tagKeys and ratedFactors
- GET and PATCH /api/custom-metrics/{id} carry latest and entryCount
- /api/analytics no longer leaks anomalyCount through the per-night sleep
summary and the glucose meal-context split
The title of a Coach conversation is the first 80 characters of the
opening message, and the note on a custom-metric reading is free text;
both were stored readable while every other note was encrypted.
Migration 0357 adds coach_conversations.title_encrypted and
custom_metric_entries.note_encrypted (the title loses its NOT NULL) plus
partial indexes on the backfill's discovery predicate. Every writer now
stores ciphertext only: conversation create, proactive nudge, reminder
surfacing, rename, entry create and edit, and both restore formats.
Readers prefer the ciphertext and fall back to the old column for rows
not yet migrated; a ciphertext that does not open throws instead of
falling back. The history title search decrypts in memory, since SQL can
no longer match the title.
free-text-encryption-backfill is a boot-time, idempotent pg-boss job
(staggered past the startup storm, daily discovery tick) that seals each
remaining readable value and nulls it in one transaction per row. A pass
that sees a row twice stops with an error instead of looping.
Both columns are registered for key rotation (registry, CLI script, and
the in-app rotation that walks the registry). A disaster-recovery backup
carries ciphertext only, sealing a not-yet-migrated row on the way out;
a portable export carries readable text. The old columns are marked for
removal in a later release.
Add a user-defined custom-metric store alongside the built-in measurements
on the Measurements surface. A user defines an arbitrary metric (name, unit,
optional target window, decimals, description), logs values, and charts them.
The store is a separate generic catalog + values pair, isolated from the
closed measurement-type system: not synced, not in FHIR, not in insights —
log and chart only. Names and units are plaintext, mirroring the biomarker
catalog. The inline list lives beneath the measurement list (no new nav
entry); tapping a metric opens a detail page with the trend chart, target
band, stat strip, and an editable value history.
Migration 0224 adds custom_metrics and custom_metric_entries.
