- The daily Coach sweep now charges each ignored day against
surfaceCount and auto-dismisses at three — the cap the schema comment
promised since v1.22 but nothing enforced.
- The welcome gate compares the stored disclaimer acknowledgment
version against the current one, so revised disclaimer text
re-prompts; /api/auth/me carries the version for the client.
- slope90 and anomalyCount leave the analytics wire: slope90 had no
reader anywhere (computed on every request, in SQL twice), and the
slim path could never compute anomalyCount (it always reported 0).
anomalyCount stays as an in-process field on summarize() for the
insights feature builder, which is its only real consumer.
The mood series has been local-day-keyed since v1.32.12, but the metric
partners it joins against (blood pressure, weight, resting pulse) were
still keyed on the UTC calendar day. The join is an exact day-string
match, so for anyone outside UTC an evening reading landed on the next
UTC day and paired with the wrong mood entry — a one-day misalignment
sold as a same-day correlation.
Derive the three mood pairing partners as exact local-day means, keyed in
the user's own timezone via userDayKey (Intl-based, DST-safe). Blood
pressure and resting pulse reuse raw rows already on the request path;
weight rides one additive column on the existing raw-rows query. The
UTC-consistent weight x BP and BP-medication joins are left untouched —
both their sides share one UTC key space and they migrate with the
rollup tier later.
The rollup read path windows the 7/30/90-day regression on
startOfUtcDay(now - N days), while the live-SQL fallback filtered the
REGR_* aggregates on the wall-clock NOW() - INTERVAL bound. An account
crossing a coverage boundary (warm to cold) therefore saw the boundary
day's readings flip in or out of the slope window depending only on
whether the rollup tier was populated, returning a cache-dependent
slope for the same request.
Anchor both cold-fallback paths on date_trunc('day', NOW() AT TIME ZONE
'UTC') - INTERVAL 'N days', the SQL twin of startOfUtcDay, so warm and
cold return identical boundary-day membership. The avg7/avg30/median
windows stay wall-clock since the warm narrow query computes them the
same way.
The windowed slope / r2 / sd readers compose from the per-bucket
regression accumulators (migration 0190). Between a deploy and the
boot-backfill completing, a tenant's pre-0190 DAY buckets still carry
NULL accumulators, so composeWindowedRegression returns a full miss and
the slim / comprehensive readers emit a null slope. The null is the
honest answer until the backfill refills the accumulators, but the miss
was passing as a plain rollup read with no signal, against the no-silent-
cap rule.
Add hasPendingAccumulatorBackfill to the read tier and key a new
regression_source annotation off it (unavailable_pending_backfill vs
rollup) on both warm paths. No live-SQL fallback is added; the design
intentionally avoids the heavy scan.
The summaries slice (computeFromRollups) and the comprehensive aggregator
(buildFromRollups) each ran a narrow live $queryRaw over the raw
measurements partition on EVERY warm-rollup request to fold slope7/30/90
and r2_7/30/90 via REGR_SLOPE / REGR_R2 - the un-eliminated live scan on
the happy path.
Drop the six REGR_* columns from both narrow queries and compose the
windowed slope / r2 (and the population sd via composeRegression) from
the per-bucket accumulators stored in measurement_rollups. The 90-day
DAY buckets are loaded once (already loaded in comprehensive; one bounded
findMany added in the slim slice), source-collapsed to the canonical
source, then summed over the day-aligned 7/30/90-day sub-windows. A
window whose buckets lack accumulators (pre-backfill) composes to null,
the same shape the empty REGR_* FILTER returned, so a transitional read
never returns a wrong partial regression.
median (PERCENTILE_CONT) and the exact |z|>2 anomaly count stay on the
minimal live query - both are non-composable across buckets. The cold
coverage-miss path keeps the live REGR_* regression. Annotate
slope_source:"rollup" + median_source/anomaly_source:"live" so a
regression to the heavy path stays observable (no-silent-cap rule).
The warm narrow query and the cold heavy query each referenced the
canonical-source subquery twice — once in the window_stats CTE and once in
the outer body — so the DISTINCT-ON pick over the live 90-day rows ran twice
per rebuild. Extract canonicalMeasurementsCte (the SELECT body without the
alias wrapper), bind it once as WITH cm AS (...), and select FROM cm m from
both window_stats and the outer aggregate. Output is identical; the dominant
self-join runs once.
canonicalMeasurementsFrom now wraps the same body, byte-stable for the
single-reference call sites (pinned by a new parity test).
The raw BP pulls in the comprehensive aggregator and the bp-in-target live
fallback read every source's row for BLOOD_PRESSURE_SYS/DIA. BP is a
multi-source metric — a Withings reading mirrored into Apple Health is two
rows for one event — so each shared reading was counted twice in the
in-target denominator and twice in the recency-weighted grade. The rollup
branch of the same fast-path reads source-collapsed measurement_rollups, so a
rollup-warm account and a rollup-cold account returned different BP
percentages and grades for identical data — a web/iOS and cold/warm parity
break.
Route both raw pulls through canonicalMeasurementsFrom so the cold/live path
picks the ladder-winning source per (type, day), matching the warm/rollup
path. Per-event rows of the winning source survive the collapse, so the
downstream 5-minute pairing still sees individual readings.
One-shot prettier pass so the new format:check gate starts from a clean
baseline. Formatting only — no behaviour change. Generator-owned and
vendored artifacts stay untouched via .prettierignore.
Complete the source-aware rollup read path: the slim summaries slice
(rollup + live), the comprehensive aggregator (both paths, including the
dailyByType correlation feed), and the /api/measurements route (rollup
read + the live date_trunc fallback) now resolve overlapping sources to
the source-priority ladder's canonical reading per (type, day) before
aggregating. A dual-source vital (e.g. WHOOP + Apple Watch resting heart
rate) surfaces one canonical series instead of a blend or a doubled
count; cumulative metrics keep summing per canonical source.
The collapse runs in SQL where the aggregate must stay a single
round-trip (buildSourceRankCase emits a per-user ladder-rank CASE;
canonicalMeasurementsFrom restricts a live read to canonical-source rows)
and in application code (collapseRollupRowsBySource) for the row readers,
both driven by the same resolved ladders so live and rollup agree.
Also widens the enum-literal SQL whitelist to accept digits so VO2_MAX
no longer throws on the typed write-hook recompute or the rank CASE.

Add the data-value features to the insights category pages on top of the
density pass:
- Stat strip: lead each metric page with min / max / median / mean,
read from the already-fetched analytics summaries slice (no new
network). Median is now computed in both summary producers — exact in
the live path, a windowed PERCENTILE_CONT in the rollup-tier slim
slice. The thin HealthKit pages mount it too for parity; no AI
assessment is added there.
- Range band: shade an Apple-Health-style min-max area around the daily
mean line where the data supports it (non-cumulative metrics). The
daily-aggregate read now emits per-day min / max from the rollup
buckets; the band rides the existing target-range toggle.
- All readings: a dedicated per-metric subpage at /insights/values/<type>
reusing the measurement list pinned to one type (pagination + inline
edit/delete). A clear entry button mounts at the foot of each
category page.
- Diversity nudge: a gentle hint when a metric's readings cluster on one
weekday or time of day, computed from a bounded, cached timestamp
window — non-blocking, self-gating.
All new reads stay cache-friendly and off the navigation path.
Eleven touch-disjoint waves landed on develop plus a six-axis QA
reconcile round before tagging. See CHANGELOG.md for the user-facing
prose; this commit message documents the wave + report inventory for
release-management traceability.
Waves shipped (each with a phase report under .planning/):
- phase-W-POOL-v1440-report.md — p-limit(4) wrapper around the
analytics 15-way fan-out + pg.Pool max raised 10 -> 20. Closes the
v1.4.39 empirical-trace finding #1 (Prisma pool starvation).
- phase-W-DELETED-v1440-report.md — 11 reader-tier helpers + 3
integration contracts close audit Critical Finding #3 (soft-delete
invisibility) across dashboard, analytics, summaries, rollup tiers,
and the Coach snapshot path.
- phase-W-INSIGHTS-v1440-report.md — mood-rollup swap on the three
/api/insights/{features,targets,cards} routes plus the
compliance-rollup hook gap closure for bulk-projection mints; the
post-QA reconcile patch closes the six remaining measurement.findMany
sites in the cluster that still leaked tombstoned rows.
- phase-W-INFRA-v1440-report.md — rollup helper umbrella consolidation
under src/lib/rollups/* with zero orphan re-exports; lint, typecheck,
knip, and 93/93 rollup tests green post-restructure.
- phase-W-RSC-v1440-report.md — per-tile Suspense boundaries plus the
queryKey factory-bypass walker test (extended to comparison/ in the
reconcile pass).
- phase-W-PRIVACY-v1440-report.md — bilingual /privacy page with 17
paired-section tests pinning the 9 SB-3 disclosure requirements.
- phase-W-AASA-v1440-report.md — /.well-known/apple-app-site-association
endpoint pinned to S8WDX4W5KX.dev.healthlog.app with app-ID parity
assertions guarding against split rotation.
- phase-W-APNS-NOTIFY-v1440-report.md — MEDICATION_REMINDER
time-sensitive APNs payload (priority 10 + interruption-level)
scoped via a parameterised test that pins all 6 other event-types
do not bypass Focus. AP-2 .p8 install gates real delivery.
- phase-W-CONSENT-v1440-report.md — AI consent receipts CRUD with
append-only invariant pinned in test; revoke-then-regrant leaves
both rows; idempotent DELETE returns 200 + receipt: null.
- phase-W-WMY-WIRE-v1440-report.md — three previously-dead WMY readers
(week/month/year) wired through summaries-slice and
health-score-fast-path with a linear-composability parity test
pinning the cross-consumer routing contract.
- phase-W-GHOSTS-v1440-report.md — ~1 177 lines of dead code removed
across 9 atomic commits; startOfUtcDay + wallClockInTz consolidation
eliminates a sibling-drift risk; knip whitelist trimmed to three
files pending follow-up.
QA reconcile patches applied per the v1.4.40 QA round (six reports
under .planning/round-v1440-QA-*-findings.md):
- senior C1 — dashboard-suspense-boundaries regex aligned with the
post-W-INFRA Thread 2 userTimezone-local lift.
- senior H1 — soft-delete filter added to the six remaining
insights measurement.findMany sites.
- specialist H1 — Promise.allSettled around bulk-projection
compliance recompute on both /api/medications/intake and
/api/dashboard/summary.
- ux H1 — compare-toggle migrated to queryKeys.dashboardWidgets
factory; walker test extended to src/components/comparison/.
- security M1 — consent artefact 64 KB cap enforced via
Buffer.byteLength (UTF-8 bytes, not UTF-16 code units).
Quality gates green at tag: pnpm typecheck, pnpm lint, pnpm knip
--include files,dependencies,binaries,unlisted, pnpm test --run
(4726 passing / 1 skipped). Tests 4525 -> 4726 unit + 1 skipped over
the v1.4.39 -> v1.4.40 span.
User-facing prose: see CHANGELOG.md.
Robustness sweep, perf hotspots, full localization, coach gate
cascade closure.
- /api/dashboard/summary cold-mount 4.6 s → ~500 ms via DAY-bucket
sparkline + 60 s response cache.
- Coach API gate inventory test surfaced and closed two orphan
routes (chat[id] GET+DELETE, chat-message feedback POST).
- Cross-tz fast-path runtime guard falls back to live for users
more than ±3 h from UTC; proper bucket minting stays v1.5.
- es / fr / it / pl coverage 27 % → 63 % (~3 400 new strings) plus
three medication-cluster placeholder restorations.
- IANA timezone validation closes the User.timezone self-DoS
regression the new dashboard SQL would have surfaced.
- Unit suite 4520 → 4524.
See CHANGELOG.md for the full set.
Hotfix on top of v1.4.37. The post-deploy verify caught
/api/analytics cold-mount hits of ~62 s and parallel /api/health
checks of ~58 s on the live instance, far above the v1.4.37
1.5-3 s perf claim. Root cause: the synchronous
ensureUserRollupsFresh(userId) call at the top of each heavy
read path folds the trailing 90-day DAY window when the rollup
watermark trails the newest measurement. On a power-user account
whose iOS step samples push the watermark every few minutes,
each cache miss synchronously paid the full refresh cost on a
Node worker that also serves the rest of the request fan-out
(including /api/health, /api/version, and concurrent iOS calls),
and the event loop was blocked for the duration of the
recompute.
Convert the three call sites (analytics route, comprehensive
aggregator, summaries slice) to fire-and-forget. The downstream
probeRollupCoverage gate falls back to live SQL on partial
coverage so correctness is preserved; the only user-observable
change is one cache window of staleness on the very first
request after a new measurement landed.
Heavy-aggregate skip on the rollup-fresh + fully-covered path,
daily chart fetches opt into rollup buckets via source=rollup,
Insights extractFeatures swap drops the prompt payload from
double-digit MB to the low hundreds of kB on power-user accounts,
page-level isLoading gate replaced with per-section early-skeleton
paint, trends-row chart slot pinned for CLS, IntakeHistoryListV2
restored on the medication detail page, About card folded into the
Admin Console with an auto-checking update badge, cumulative metric
tiles read the day's running sum, IP-whois fallback surfaces city
+ country when the ASN lookup misses. Migration 0068 adds an
additive users.insights_exclude_metrics column. Unit suite 4354
passing; typecheck + lint clean.
Foundation release for the persistent measurement_rollups cache tier.
Adds the additive table + enum, populates it from every measurement
write hook, lands the Apple-Health-import end-of-job backfill, and
ships the parity-checked read-swap on two reader surfaces.
The comprehensive insights aggregator and the slim analytics
summaries slice now source count / min / max / mean per type from the
DAY rollup buckets via aggregateBuckets, plus the comprehensive
dailyByType correlation feed straight from the bucket means. Slope /
R² / standard deviation / anomaly counts stay on live SQL — they do
not compose across DAY buckets. A defensive parity check against the
live aggregate's COUNT(*) falls back to live SQL when divergence is
detected.
Includes the new scripts/backfill-rollups.ts CLI for the one-shot
fold of historical measurements into all four granularities.
Tests: 4280 unit + 228 integration. tsc + lint clean. Migration
0067_v1434_measurement_rollups is idempotent under re-run.
Hotfix on top of v1.4.34. The Insights page mount was paying ~29 s on
every cold load against accounts populated by the v1.4.34 Apple Health
importer. Root cause: `/api/insights/comprehensive` walked the unbounded
90-day measurement set into JS, then ran per-type `summarize()`, BMI,
blood-pressure classification, target adherence, and four Pearson
correlations from the same pile of rows. On a 100 000+ row account the
route consumed one of the 20 pool connections for the whole 29 s, which
cascaded sibling endpoints into Cloudflare "no available server" 503s.
The scatter-correlation card also surfaced a `width(-1)/height(-1)`
Recharts warning on first paint because its dynamic-mount lacked a
non-zero floor before aspect-ratio resolved.
Changed:
- /api/insights/comprehensive now reads through a SQL-side aggregator
(src/lib/insights/comprehensive-aggregator.ts) grouping by metric
type with Postgres-native AVG / MIN / MAX / REGR_SLOPE / REGR_R2 on
the measurements (user_id, type, measured_at) index path. Returns
the same DataSummary-shaped per-type bundle the legacy route
stitched together; the medication-compliance block keeps its
bounded Prisma reads. Wrapped through the server cache keyed on
`${userId}|comprehensive` (60 s TTL). Cold path drops from ~29 s
to a few hundred ms against fixture data matching the production
volume that triggered the bug; warm path resolves in single-digit
milliseconds.
- Cache-wrap the five remaining read routes the v1.4.34 server-cache
blueprint left staged but unwired: /api/mood/analytics,
/api/workouts, /api/bugreport/status, /api/medications,
/api/dashboard/widgets. The Cloudflare 503 cascade on
/api/measurements?aggregate=daily resolves as a downstream
consequence — once the comprehensive route stops monopolising the
pool, the origin accepts new connections fast enough that
Cloudflare's circuit-breaker no longer trips.
- /api/dashboard/chart-overlay-prefs PUT now invalidates the new
dashboard-widgets cache so the partial-update path doesn't leave
stale layout state in the cache for up to TTL.
Fixed:
- Scatter-correlation card no longer logs the Recharts
`width(-1)/height(-1)` warning on first mount. The wrapper now
carries a min-h-[180px] floor that matches the loading skeleton so
ResponsiveContainer always measures a non-zero parent before
aspect-ratio settles.
