The canonical picker re-sorts its output to startedAt ASC for its rollup callers, so the list route sliced the oldest page and recent workouts never surfaced on a long history — re-establish newest-first after the pick. And a workout from a previous year now shows its year so it is not read as this year's.
Fluid intake and device-recorded vitamins/minerals get a home: a dashboard water tile with quick-add, and a Nutrients page under Insights showing hydration over the last month, caffeine, and the micronutrients with data — each against its reference intake as context. Manual and device-synced water coexist via a source-aware day-total key.
WHOOP workouts map to canonical sports (bike rides show as cycling) with a history backfill and a richer cross-source merge; the intraday heart-rate view gains a day navigator with 90-day dense retention and an hourly fallback for older days; milestone/ECG/tension cards can be dismissed from Today; vitals context moves into an (i) popover and the VO2max heading no longer clips; Oura cycle phases feed the cycle tracker where available.
Today refreshes right after a dose; a calmer Today hero; the Coach names the attached document; a fresh install starts with tracking on; the vitals explainer line is removed; the illness journal gains an editable end and a settled course line; the morning refresh now triggers from every sleep source and records each skip.
The capstone of the daily-value milestone. On top of the Today view, the daily
loop (coach check-in, morning freshness, daily note) and the documents/coach
work already shipped, this completes the picture:
- ECG woven into the insights narrative (device-attributed only, never the
app's own reading; a new recording surfaces gently in Today).
- Intraday heart rate as the shape of the day, with a careful elevated-at-rest
tension note (never during activity, never a verdict).
- Calm milestones — states reached, not streaks to keep.
- The cohesion layer: the chosen health rings return to the Today hero, each
surface carries its metric's calm colour identity, and a quiet reached-moment
for a milestone — one design throughout.
No new data collected; every daily surface reads the overnight digest. No
migration in this release.
Bundles the documents/coach slices onto the daily-system release:
- Ask the Coach about a document opens in a side panel (expandable to full
page), not a full-page jump.
- Attach one or more documents to a Coach chat from the composer (pick from the
vault or upload); the conversation runs fenced — grounded in those documents
only, no health data or tools — and can never reach the tool loop (a sticky
document-scoped flag plus dual client/server enforcement; migration 0245).
- A read document that looks like lab work has its values detected and proposed
for your labs, added only on your one-tap confirm.
- A lab scan is also filed in your vault (encrypted) and linked to the readings.
Adversarially security-reviewed (multi-document attach): all clear.
Bundles three daily-loop slices onto the Today view:
- Coach check-in: a due plan review surfaces as a calm Today card with
keep/adjust/let-go, wired to the existing plan lifecycle; silence never
changes a plan.
- Morning freshness: the sleep-dependent parts of the digest and score refresh
the moment last night's sleep arrives (a debounced, timezone-correct per-user
job across the Withings, WHOOP and Apple transports), with an honest
provisional state until then. Adds migration 0244 (a per-user refresh marker).
- Daily push: an opt-in, once-a-day morning notification carrying the day's
read, off by default, riding the existing dispatch cascade — a calm note,
never an alert.
All read the overnight digest; nothing generates on open.
Retires the legacy opt-in dashboard hero now that the Today view leads the
dashboard, so the two never stack. Removes the hero mount, its skeleton, the
carousel/spotlight components only it rendered, and the heroVisible layout
field (a stored layout that still carries it is ignored on read, never
re-persisted, so nothing to migrate). The greeting is now always shown. The
mobile-density guard measures the Today hero.
The score-ring selection stays in the layout contract for the native client;
its web picker is a follow-up decision (resurface in the Today view or leave it
native-only).
Bundles the daily-digest spine (a single server-built digest read from the
overnight insight cache, never a fresh generation) and the Today hero that
surfaces it: the health score with an honest provisional/finalised face, the
day's lead read, and a short worth-a-look rail of one-tap items. The tiles and
charts stay below, unchanged. The Today hero takes the promoted slot when
Insights is on, so it never stacks with the legacy opt-in hero.
This is the shared foundation the later daily surfaces (morning refresh, an
optional daily note) build on — one digest, one card model, one design language.
Several readings were synced and charted but had no place on the dashboard
strip: heart-rate variability, blood oxygen, breathing rate, wrist temperature,
and — for body-composition scale users — muscle mass, body water, and bone mass.
Each now has a tile.
The tiles are pure client additions: the dashboard snapshot already ships a
summary for every measurement type, so no backend, query, or migration changed.
Each tile is data-availability gated (renders only when the account has that
reading) and is toggleable and reorderable under Settings like the rest.
hrv and respiratoryRate graduate from iOS-only to web-writable widget ids, and
muscleMass is a new writable id (catalogue 36 to 37, within the 40-id PUT cap);
wristTemperature moves from pin-only to a web-rendered tile. All additive — the
widget enum only widens, which the iOS contract treats as non-breaking.
Asking the Coach about a document opened a separate, half-finished chat panel
that never appeared in Coach history. The bespoke drawer is gone; a document
conversation now opens the real Coach view, appears in the Coach list with a
document badge and a "Chatting about: <title>" note, and is read back through
the same history rail as any other thread.
The prompt-injection fence is unchanged and stays server-side. A document turn
is still sent through the hardened fenced endpoint (no tools, no health
snapshot, grounded in the document text only); the coach tool route continues
to fetch with documentId null, so a document-scoped conversation can never be
continued through the tool loop even from a hostile client. Only the surface
moved into the Coach; the boundary did not.
The relaxed conversation-list and detail filters drop only the documentId
predicate — userId scoping is unchanged, so a document thread is still visible
only to its owner. CoachConversationDTO gains documentId + documentTitle
(server-derived, title/filename only); no schema change (documentId exists
since 0230). OpenAPI regenerated.
ECG recordings synced from a compatible watch were stored encrypted but
shown nowhere. They now have a surface in Insights: a list of recordings,
each opening the full single-lead waveform on a familiar ECG grid, with the
date, duration, average heart rate, and the result the device recorded.
The read routes narrow ownership in the query and decrypt the waveform
through the existing fail-closed codec; the overview is min/max-decimated so
the R-wave peaks survive the reduction, with a raw path for a calibrated
view. The result shown is the recording device's own classification,
attributed to the device — HealthLog does not read or interpret the trace
and produces no verdict of its own. A permanent note states this, and a
non-normal result carries a line to discuss the recording with a clinician.
The Apple Health ZIP import upserted each spot reading on the
(userId, type, source, externalId) index only. When two readings shared the
natural key (userId, type, measuredAt, source, sleepStage) with different
externalIds — a re-import of overlapping data, or two same-instant Apple
samples from different source apps — the externalId upsert missed and the
create collided on the second unique index (migration 0055), raising P2002
and aborting the entire import (issue #486, after the v1.28.36 dedup fix let
the upload run).
flushSpotBatch now wraps the per-row upsert: on P2002 it probes the occupying
row by the natural key (tombstone-inclusive) and adopts it in place — re-keys
to the incoming externalId, takes the new value/unit, resurrects if
soft-deleted — mirroring the v1.28.39 provider natural-key rescues (closest to
withings/sync-sleep). If no twin resolves it, the one reading is skipped and
the run continues; the catch sits in the per-row loop outside any transaction,
so a collision can never abort the batch or the import. Adopted rows count as
updated, skipped ones surface honestly. Workout + stats: paths verified unable
to hit this (no second unique index / deterministic externalId). Repro +
real-Postgres integration tests added.
From the campaign's security re-verification pass (posture otherwise held
across the 10-release week — no Critical/High):
- MEDIUM: the OIDC auto-provision branch re-introduced the first-admin race
the password-register route fixed in v1.28.42 — count-then-create with no
lock, so two concurrent OIDC first-logins (or an OIDC first-login racing a
password first-registration) in the empty-DB window could both mint ADMIN.
Now wraps count+role+create in a $transaction taking the SAME advisory lock
key ('register:first-admin') and re-counts inside, so the two paths
serialise; every provisioned field preserved.
- LOW: the nutrients batch catch echoed the raw exception message into the
client-facing reason (violating its closed reason-set). Now returns the
fixed 'upsert_failed' member and logs the detail server-side only.
No migration (advisory lock is runtime).
Bumps pg-boss 12.20 → 12.26 (schema-drift detection, self-healing background
index builds, correctness fixes). Some of those fixes surface errors earlier
versions silently swallowed. Verified safe: the app attaches an error listener
to the boss instance (reminder-worker.ts) and uses none of the direct calls the
change affects (insert/fetch/deleteQueue) — only send/work/start/stop/schedule/
getJobById, and the one getJobById is already wrapped in try/catch. The full
integration suite (101 files, 497 tests) exercising the queue against real
Postgres passes unchanged under 12.26. No config change.
Deferred perf fixes from the campaign's verified perf-correctness audit,
correctness-first (each with an output-equivalence test):
- comprehensive-generate fan-out: replaced per-type 400d findMany+JS-average
with DB prisma.aggregate(_avg) over the exact half-open windows the JS
reducer used (current 30d, lastMonth (60d,30d], lastYear (395d,365d]), same
rounding + null-on-empty, pLimit(4). SLEEP_DURATION stays on the raw path
(per-night reconstruction dedup). Byte-equality test vs the old algorithm.
- boot-discovery: replaced Prisma in-memory distinct with DB SELECT DISTINCT
in the 4 backfill discovery scans + migration 0243 (7 additive
partial indexes matching each predicate). Integration test asserts identical
discovered set against real Postgres.
- ChatBubble wrapped in React.memo with a comparator (onRegenerate compared by
presence — the thread rebuilds it each render), so only the streaming bubble
re-renders per token.
- doctor-report mood read narrowed to {score, tags} (the only fields the
collector uses); the 730d main measurement read left as-is — a blind bound
would corrupt clinical stats (documented deferred follow-up).
Migration 0243 additive-only.
Three CONFIRMED findings from the campaign's feature-wiring audit + structural
verification:
- Sleep rendered nothing in the doctor-report PDF: the sleep section is
default-on and the data layer reconstructs per-night SLEEP_DURATION rows, but
DOCTOR_REPORT_VITAL_TYPES omitted SLEEP_DURATION, so the vitals table showed
nothing (FHIR already emitted it). Added it to the allowlist with a
minutes-to-hours conversion; corrected the stale 'intentionally excluded'
comment.
- Glucose had no doctor-report section toggle — it rendered whenever the global
glucose module was on, with no report-level privacy control. The toggle
actually already existed in the UI (with i18n) but was dead because the prefs
fold dropped the key. Wired it end to end (glucose added to the prefs Zod
schema + defaults, default-on to preserve behaviour; gated the render loop +
the query). Also fixed a grouped-vs-flat prefs mis-detection: 'glucose' in
GROUPED_SECTION_KEYS would have flagged flat blobs (incl. EMPTY prefs) as
grouped and defaulted them all on. No migration (prefs is a JSON blob).
- environment fed the coach with no exclusion: MODULE_EXCLUDED_SOURCES omitted
it, so module-off still leaked audio_env/audio_headphone/audio_event/daylight/
skin_temp to the snapshot. Added, scoped exactly to the environment cluster's
five sources.
Regression test per fix.
From the campaign's dead-code + code-health audits (grep-verified; the
custom-metrics query-key finding was verified-false and excluded):
- sleep-overview empty-state CTA linked to /settings/devices, not a valid
settings slug (dynamicParams=false → 404). Repointed to
/settings/integrations (where every device OAuth callback already lands).
- six live, iOS-consumed routes were absent from docs/api/openapi.yaml —
auth/check-user, insights/cards, integrations/healthkit (GET+PATCH),
measurement-categories, medications/intake/bulk, mood-entries/bulk —
registered in the Zod OpenAPI registry mirroring each handler's real shape.
- mood/labs/medications module pages lacked the redirect-when-off self-guard
their siblings have; added, mirroring cycle/achievements exactly.
No migration. Verifier REJECTED the custom-metrics bare-key finding (they are
invalidateQueries prefix filters, not colliding useQuery keys).
Verified UI-consistency findings from the campaign's design audit, each
pixel-faithful except the intended correction:
- insights hero band: off-scale py-5/gap-5 → the standard scale; H1
font-semibold → font-bold; sm:text-[28px] → sm:text-3xl.
- medication-compliance-chart + recent-achievements-card: hand-rolled
muted h-4 icon + text-sm headers → the standard TileHeader primitive so
they match sibling tiles.
- achievements stat tiles + clinician-view shells: p-5 → p-4 md:p-6.
- two text-primary header glyphs (research-mode dialog, enroll-mfa) →
text-foreground (never accent on a header glyph); the deliberate
badge-boxed icons left untouched.
- SheetHeader now reserves the trailing close-X gutter like DialogHeader,
closing the latent overlap class for future raw-Sheet consumers.
- five raw Dialogs on phone-reachable surfaces → ResponsiveSheet.
- new bg-card-scoped healthlog/spacing-scale lint (flags p-5/gap-5 etc.
only on card shells; list-marker insets + half-steps excluded) at error,
with the five offenders it flagged swept.
- dropped the stale CLAUDE.md '18 PascalCase outliers' line (0 remain).
Every data-slot preserved. No migration.
Performance + correctness fixes from the campaign's verified perf-correctness
audit (the two server-query findings — comprehensive-generate + boot-discovery
distinct — are deferred to a careful separate perf release):
- format-locale built a fresh Intl.DateTimeFormat/NumberFormat per call
(main-thread stall across every history list). Routed through the existing
process-wide formatter-cache keyed on locale + options (timeZone + hour-cycle
in the key); output byte-identical.
- measurement-list rendered every row twice (desktop table + mobile cards, one
CSS-hidden), unvirtualized. Now renders one layout via the SSR-safe
useIsMobile(md) hook; row markup + every data-slot unchanged.
- moodDependentKeys omitted dashboardSnapshot(), so a mood write left the
dashboard tile/score stale ~120s (server cache was already correct). Added it.
- register first-user admin was a count-then-create race (two concurrent
first sign-ups could both become ADMIN). Now an advisory lock + in-transaction
re-count makes first-admin atomic; P2002 maps to 409 instead of 500.
Regression test per fix. No migration (0243 still free).
illness.vital.FUNCTIONAL_IMPACT (the recovery-driver track that wins ties
in the illness insights card's driver selection) was referenced but absent
from all six locale bundles, rendering its raw dotted key on a live
surface — the same dynamic-key seam that let the WHO-5/SCI reminder labels
ship untranslated. Added the label in de/en/es/fr/it/pl.
Closed the class structurally: a new enum-driven
dynamic-key-exhaustiveness test imports the source enum/const for each
high-value dynamic key space (illness scan types + functional-impact,
illness type/lifecycle, allergy + family-relationship records enums, the
mental-health instrument slugs — the WHO-5/SCI seam) and asserts every
member's built key resolves non-empty in all six locales, so a missing
translation fails CI instead of reaching a user. Fallback-protected spaces
(Strava raw sport_type) and structurally-unreachable keys are documented
as excluded. Removed one confirmed-orphan key (illness.vital.SKIN_TEMPERATURE,
zero call sites).
The per-metric insight assessments opened on the current value and read as
a data readout, while the overview texts lead with the day's verdict and
land the warm, motivating tone. Diagnosis (campaign insights-copy audit +
verification): identical warm persona/contract fragments, but the
per-metric USER prompt instructed number-first while the overview
instructed verdict-first, and the opener-hint rotation was wired into
briefing/scores/Coach but never the per-metric path (so the base prompt's
'do not open with the number' clause stayed dormant there).
Rewrote the seven per-metric assessment user prompts (generic archetype +
six bespoke: BP/weight/pulse/BMI/mood/compliance + overall) verdict-first
in EN+DE — meaning first, the number right after as support; grounding,
non-diagnostic framing, no-vendor and no-markdown all preserved (only
clause order changed). Wired openerArchetypeHint into metric-status and
the bespoke generators. Factored a shared openingShape contract into
shared-contracts so overview/per-metric/scores can't drift again, with a
coverage test. Lifted the three deterministic first-paint fallbacks to
verdict-led. Prompt-contract regression tests added. No new model calls,
token budget flat.
Four verified HIGH data-integrity fixes, each in-place per-provider (no
shared helper), from the campaign's data-integrity audit + adversarial
verification:
F1 — drain-per-sample-cumulative buildScanWhere was the only one of four
sibling drains missing deletedAt: null; the nightly cumulative fold
re-summed soft-deleted Apple samples and hard-deleted the legacy-steps
audit tombstones. Added the filter (mirrors consolidate-daily-mean,
dense-intraday-retention, consolidate-legacy-steps).
F2 — the additive late-fold merge had no single-flight guard, so two
overlapping runs (deploy overlap, or the admin endpoint racing the cron)
produced a permanent 2x daily total. Added a pg_advisory_xact_lock per
(user, externalId) plus an in-transaction re-read of the live
contributors so the serialised-second fold contributes zero (a bare lock
alone would still re-add its stale scanned sum). Mirrors the documents
quota advisory-lock pattern.
F3 — Withings sleep externalId keyed on segment START while measuredAt +
the natural key use END; a re-scored segment missed the externalId probe,
the sweep tombstoned the old row, and the re-keyed insert collided on the
natural key and wedged. Added the natural-key rescue (re-key in place),
mirroring the same-file measure path.
F4 — Withings measure sync stamped lastSyncedAt + recordSyncSuccess
unconditionally after a warn-only per-row loop; a transient write failure
stranded the reading behind the 10-min overlap forever. Now holds the
watermark and records failure on a hard row error (mirrors
google-health/fitbit), while a benign P2002 still advances.
Regression test per finding (reverting the three source files fails
exactly four tests). Integration suite green against real Postgres.
Document vault: card list drops a stray glyph and gives the real filename
its own line (was truncating on the meta row); the detail sheet's close
button aligns correctly — ResponsiveSheet reserved the right gutter for a
close button it wasn't rendering, now conditional on showCloseButton. The
open-in-coach action reads 'Coach fragen'.
Bulk share: a multi-selection in the overview shares several documents in
ONE link (documents-only privacy preserved, owner-scoped, up to 50 per
link; >50 refuses with a toast rather than silently truncating).
Reminders can link to WAIST_CIRCUMFERENCE (additive MeasurementReminderType
enum value, OpenAPI regenerated). The WHO-5 and SCI well-being reminder
labels were absent in all six locales and rendered their raw dotted keys
(the shared 'measurementReminders.types' prefix is what showed as the stray
'Measurement Reminders Types'); added in every language. A new
type-labels-i18n test asserts every dynamic reminder-type key resolves
non-empty in all six bundles — the static coverage guard cannot see the
dynamic key that let this through.
The v1.28.33 rollup + staging fixes were correct but never reached the
reporter's case: the upload dedup keys on the content SHA-256 and the
lookup matched a previously FAILED job too, so re-uploading the same
export.zip returned the dead job's id and replayed its stale
failureReason without ever staging or sending again. The dedup now
excludes failed rows (short-circuits only on queued/unpacking/parsing/
upserting/done); the same bytes retry cleanly. A redundant staged upload
is unlinked on a dedup hit instead of leaking in the staging dir.
reconcileOrphanImportJobs no longer unconditionally fails every
non-terminal ImportJob at boot: it now checks pg-boss job state plus a
progress heartbeat (new import_jobs.updated_at, migration 0242), so a
split or multi-worker deployment cannot kill an import running in
another worker. The missing-staging message names the separate-container
cause explicitly, with a matching note in docs/self-hosting/scaling.md.
Client-rendered times fell back to the hardcoded display zone
(Europe/Berlin) because neither useFormatters() nor the legacy format.ts
helpers ever received users.timezone. A third localStorage mirror
(timezone-mirror.ts, following the time-format/date-format pattern)
carries the validated profile zone from /api/auth/me into both read
paths; the fallback chain is strictly profile → Europe/Berlin — never
the browser zone, so screen, PDF, and export cannot disagree.
makeFormatters validates its zone before Intl (a poison value falls back
instead of throwing inside every render).
Same pass, per the two-document audit: formatUpdatedLabel boundary and
clock now resolve one zone in every state (the undefined-tz browser hole
is closed); @db.Date calendar fields render UTC-pinned so profiles west
of UTC cannot shift a day; dose-history day headings and GLP-1 weekday
labels derive from the display zone; chart day/month labels are
encoding-derived and UTC-pinned (bucket math untouched, byte-identical
for Berlin profiles); the clinician share view renders in the patient's
timezone instead of the container's; Playwright pins Europe/Berlin.
Server day-key semantics, streak anchoring, insight cache keys, and
verbatim wall-clock strings are untouched by construction and pinned by
the new Auckland/New_York/Manila + DST test matrix.
Supplement-style intake written to Apple Health by nutrition apps —
vitamins, minerals, water, caffeine — can now sync as daily totals into a
dedicated NutrientIntakeDay store (migration 0241): composite (user, day,
nutrient) identity, re-post replaces, no soft delete, no rollup coupling.
A code-side catalog carries the 26 nutrient codes with canonical units,
plausibility caps, and EFSA dietary reference values (direction-aware;
chromium cites NIH ODS where EFSA declined a DRV).
Deliberately not a nutrition feature: no diary, no calories, no dashboard
surface. POST /api/nutrients/batch is gated behind the new opt-in
nutrients module (default off — with the module off the server refuses
ingest entirely), rate-limited, idempotency-wrapped, with per-entry
unit-mismatch and out-of-range skips. GET /api/nutrients serves a
catalog-ordered summary; the only visible surface is a read-only card
under Settings → Sources. Coach/correlation access is a later slice; the
iOS reading side is coordinated in the companion-app tracker.
Rollup writes were delete-then-createMany inside a transaction; under READ
COMMITTED a concurrent recompute racing the import's full fold on the same
(user, type, granularity, bucket, source) partition tripped the composite
PK — and the P2002 swallow dropped the loser's freshly computed aggregate,
leaving a stale bucket. persistRollupRows now writes chunked
INSERT … ON CONFLICT DO UPDATE with deterministic (type, source, bucket)
lock ordering inside one transaction: a race can neither fail the import
nor lose an aggregate, and previously-staled buckets self-heal on their
next recompute. The vanished-source delete and in-transaction guarantees
are preserved; the now-unreachable P2002 swallow is removed.
The masked ENOENT is gone with it: long imports outlived the queue's
15-minute expiry, pg-boss redelivered the still-running job, and the
redelivery re-opened the consumed staging file — overwriting the real
terminal state with a raw ENOENT. Import sends now carry retryLimit 0 +
6h expiry (a retry after the staging file is consumed can only mask),
deliveries for terminal ImportJob rows are no-ops, a genuinely missing
staging file reports an honest re-upload message, and the extracted XML
is cleaned up on failure too.
Adds an OpenID Connect relying-party login path (PKCE authorization-code
flow) against a single env-configured identity provider — additive to
password/passkey login by default, with an operator opt-in (OIDC_ONLY,
enforced server-side on every auth route) to disable them entirely.
First-time sign-in auto-provisions or links an account by verified email.
Closes an open redirect in the post-login `next` parameter (both the new
OIDC path and the pre-existing password/passkey flow shared the same
backslash-normalization bypass) by resolving the target through a real
URL parse and comparing origins instead of a prefix check.
Single-fix release mirroring the Google Health natural-key rescue from
v1.28.28 into the Fitbit sync. The measurements natural-key unique index
(user, type, measured_at, source, sleep_stage — NULLS NOT DISTINCT,
migration 0055) covers tombstoned rows, so a re-import carrying NEW
externalIds for previously-removed rows collided on the natural key and
skipDuplicates dropped the insert silently. Every planned create now gets
a second chunked probe by natural key with no deletedAt filter; a match —
live or tombstoned — is updated in place with the fresh value, the new
externalId, and deletedAt: null. Probe failure notes the hard-failure
ledger so the watermark holds and the next tick retries. No other code
path touched.
Long-term retention for the dense intra-day tier (PULSE, HRV, SpO2) folds
to per-local-hour means instead of a single daily mean: the last 14 days
keep every raw sample, older days keep up to 24 points per metric — the
day's shape survives permanently at ~9k rows/metric/year. Hourly rows key
as stats:<HK>:<YYYY-MM-DD>T<HH> anchored at local HH:30, adopt-in-place
against both unique indexes with the P2002 retry outside the transaction.
The pre-fold DAY-rollup recompute extends to HRV (mean fidelity, not only
min/max) and the post-fold recompute is gone for the whole tier. Derived
resting rows for proxy users still mint from the day's raw samples.
A one-shot rebuild reconstructs the hourly shape for every already-folded
day from the soft-deleted raw samples and retires the daily row in the
same transaction — at no instant are both grains live, so no
AVG-over-live-rows reader can double-count. Boot discovery pairs live
daily-grain rows with surviving tombstones (parameter-bound SQL, pinned
against real Postgres) and converges to zero once converted; days whose
tombstones were pruned keep their daily mean. PULSE/SpO2 DAY buckets keep
the true pre-fold stats; HRV DAY buckets recompute from the hourly rows
(strictly better than the collapsed fold-time bucket); WEEK/MONTH/YEAR
respans enqueue whole-bucket recomputes.
