Add an on-demand intraday layer to the pulse insight: 10-minute mean
heart rate for the viewed day, folded from raw samples via the read-swap
pattern (never persisted as 10-minute rollups for all history). Draw the
personal resting baseline and softly shade any sustained
elevated-at-rest stretch.
The tension signal is not raw heart rate — it is heart rate held above
the personal resting baseline while movement is low (the elevated-at-rest
window), so a workout or a walk never reads as tension. Detection is
deliberately conservative: baseline maturity, per-bucket sample density,
a mandatory step-based low-movement gate, and a minimum sustained
duration must all hold before anything is reported. Silence over
speculation.
Surface the same signal as a calm, non-diagnostic tension_window item in
the daily digest — at most once per day, honest-absent otherwise, gated
on the insights module and yielding the rail to time-sensitive actions.
Cautious copy across all six locales; framed as "possible tension", never
a clinical stress verdict.
Add the durable-states Milestone primitive and a milestone card to the
daily digest. A milestone marks a state REACHED, never days maintained:
a metric settled back inside its own range, a run of weeks in range, or
a fresh personal best. It is deliberately not a streak — the type carries
a reached-date and no running counter, so nothing here can be tuned into
a flame, and a lapse is invisible rather than mourned.
The primitive is a thin wrapper over engines that already exist: the pure
detectStreak band engine (return-to-range + sustained-in-range) and the
PersonalRecord detection output (new bests). Reached-once needs no new
storage — a milestone's reached-date is a stable fact, so it surfaces only
on the day it was reached and never resurfaces the next day.
The digest emits one calm success card per day when a milestone is freshly
reached, below an overdue dose and above ambient items, with a single
action into the metric's insight. Module- and data-gated: a disabled
insights account or a day with nothing reached shows nothing. Copy carries
no streak, loss, or failure vocabulary, in all six locales.
The nightly insight pre-pass runs ~04:30, before last night's sleep has
synced, so the morning digest and health score reference the day without
the current sleep. Close the gap the event-driven way instead of an
on-mount generation.
A day's digest is now provisional until the sleep-dependent output has
been regenerated with last night's sleep, and final after. The lifecycle
is driven by a real marker (User.morningDigestRefreshedOn, the user-local
date the refresh completed), not a heuristic: it flips the instant the
refresh runs, ahead of the snapshot cache that feeds the sleep last-seen
fallback. A day with no sleep device stays honestly provisional and keeps
the sleep-pending note rather than showing a stale final score.
When a completed sleep segment for last night lands from any of the three
sleep transports — Withings sync-sleep, the WHOOP sync, the Apple-Health
measurement batch — a debounced morning-digest-refresh job is enqueued.
"Last night" is judged in the user's profile timezone, so a full-history
re-sync never re-triggers for an old night. The queue singletonKey plus
the marker collapse the many samples of one night, across all sources,
into one refresh per user per local morning; the job re-runs the same
comprehensive pipeline the nightly cron uses (forced, so the content-hash
gate turns a no-change regen into a cheap no-op) and stamps the marker. A
hard generation failure leaves the day provisional and hands recovery to
the existing 45-minute briefing-retry machinery.
Every accepted coach plan now earns a gentle weekly check-in. Confirming a
plan (proposed → active) without an explicit review date defaults one to a
week out, so a plan is always reviewed, not only the coach's own experiments.
The daily digest emits a single `coach_checkin` rail item when a standing
plan's review has come due — its pinned review date, or a defaulted
activation + 7 days for plans that predate it, or the read-back state a
reviewed plan carries. Capped at one check-in a day across all plans
(earliest-due wins); the rest wait for a following day. It reads existing
plan state only — no fresh generation, nothing warms on mount, and it is
gated on the coach module.
The card offers three one-tap actions through the existing plan-lifecycle
route: keep it (re-arm for another week), adjust it (open the coach), or let
it go (a guilt-free, respected end — the calm inversion of a streak). An
ignored check-in sits quiet and stops resurfacing after about two cycles;
its status is never changed behind the user's back.
Copy lands in all six locales.
Introduce the two foundational primitives of the unified daily-value
system, with no user surface yet:
- PriorityItem: the one wire-serialisable model behind every "worth a
look" rail item, coach check-in, milestone, and device-verdict pointer.
Its Lucide glyph is derived from the closed `kind` enum in the renderer
so the model itself stays JSON-serialisable across the API and future
native-client boundaries.
- PriorityCard: a calm, token-only, reduced-motion-aware card composed
entirely from the shipped Card / TileHeader / ProseBlocks primitives —
no new visual language, semantic-token status wash only, no markdown.
- buildDailyDigest: one pure, deterministic server composer that assembles
the day's read from data that already exists — the nightly briefing
lifted read-only from the insights cache plus the dashboard-snapshot
health score, meds-today, and sleep freshness. It computes no analytics
and never reaches an AI provider. It emits the DailyDigest DTO the Today
surface, the daily push, and a future iOS widget will all consume.
Deterministic item builders cover overdue doses, broken integrations,
and due Vorsorge reminders; the push line prefers the cached briefing
lead with a deterministic score floor so a keyless self-hoster still
gets a first-class line.
The read seam GET /api/daily/digest gathers the cached inputs, gates on
the insights module (cookie or Bearer; userId from the session), and
returns the digest. OpenAPI regenerated; the route is covered by the
module gate inventory. Digest strings ship in all six locales.
