Related to #585. Investigated the intraday pulse chart's read path
end to end: the ZIP-import raw-sample fold, the live-sync uploaded
10-min bucket fold, their merge, and the chart's render logic. All of
it treats the two ingestion shapes consistently — the chart has no
shape awareness at all, it paints whatever bucket series it receives.
No read-side or display-side defect explains a systematic density
difference between the two ingestion paths.
What was missing is visibility into the write and read sides that
would let a future report actually be diagnosed instead of
re-investigated from scratch. The batch endpoint's wide-event trace
never broke a skip down by reason, and never distinguished an
HR-bucket write from any other entry in the same request. The
intraday route's own trace surfaced only the final bucket count, with
no visibility into which shape (raw sample rows vs uploaded bucket
rows vs folded hourly rows) a day's data actually came from. Both
traces now carry that breakdown, so the next report of "the chart
looks sparser after a given date" is answerable by grep instead of by
re-deriving the whole read path again.
PUT /api/settings/ntfy reconstructed the entire stored config from the
request body. GET never returns the write-only authToken (only
hasAuthToken), so clients correctly omit it on any edit that doesn't
touch the credential — but the route treated an omitted or empty token
as "clear it", silently destroying a working notification credential on
routine edits like toggling enabled.
An omitted or empty authToken now preserves the currently stored value;
only a non-empty value replaces it. Mirrors the identical headerValue
preserve-on-empty contract already shipped on the webhook channel route.
PATCH /api/measurement-reminders/{id} persisted an explicit null cadence
clear correctly, but the immediate nextDueAt recomputation merged fields
with `updateValue ?? existingValue` — a JSON null and an omitted field
are both nullish, so the merge silently fell back to the OLD cadence for
one cycle. This hit interval-to-RRULE and RRULE-to-interval transitions
and an explicit anchorDate clear alike.
The merge now keys off Object.hasOwn(updateData, field): updateData
already encodes exactly which fields are being persisted, including the
mutual-exclusivity auto-clear (setting one cadence nulls the other), so
recomputation can never diverge from what the row ends up holding.
The Settings page's instant score-ring toggle PUT the full dashboard
layout, built from the client's cached `remote` snapshot. That snapshot
can go stale mid-flight: if a normal tile/chart Save committed a newer
layout first, the ring request's explicit stale `widgets` (and
`comparisonBaseline` / `chartOverlayPrefs`) still won on write and
silently reverted the just-saved layout whenever it resolved last.
The ring mutation now PUTs only the two ring fields
(`buildRingMutationPayload`). `widgets` joins the existing
preserve-when-absent merge (`LAYOUT_FIELD_MERGE_DISPOSITION`) so an
omitted field is carried forward from whatever is currently stored
instead of a client-held copy, closing the race regardless of request
order.
The disable-route suite only ever supplied a cookie-shaped context, which is why
the token-id-as-session-id defect was invisible to it. It now covers both arms
and asserts the credential shape handed to the session revoker, plus that the
elevation is spent before the teardown and not spent when the factor code is
wrong.
Four suites, each mutation-checked against a reverted protection:
- route-workout-scope: the workout row is read exactly once across a ten-turn
conversation that keeps sending the id, the where clause always names
userId, another user's id resolves to nothing and the chat proceeds, and
the section sits inside the health-data fence.
- workout-evidence: the numbers-only closure. An instruction-shaped
sport_type — reachable through the restore path, which types the column as
free text — folds to "other" and never reaches the block; a free-text leaf
at any depth throws.
- page-launch-params: an unknown ?scope= is ignored silently, and ?workout=
yields to both ?c= and the fenced ?doc= path.
- composite-score-anatomy-coach: every score sheet carries an opener, a
scope narrowed to the composite's inputs, and auto-send.
resolveLaunchState's shape assertion gains the workoutId field.
One test per gate, each asserting the refusal reason AND that the provider
entry was never reached — a gate that refuses but still resolves a provider
would pass a reason-only assertion while costing what the gate exists to
prevent. The cap and the hash are asserted independently of each other, since
the singleton queue key that normally collapses a burst is best-effort.
The backfill fixture walks the real chain: 750 historical sessions plus 40
re-synced ones plus one fresh, through the live classifier and the live spine
worker, yielding exactly one generation.
The peak detector changed under test: on a flat ride the ninetieth percentile
sits a beat above the mean, so a bpm of sampling noise read as two efforts the
rider did not do. Peaks now need an absolute prominence over the session mean
as well.
The spine dispatches a generator-free enqueue; the worker resolves the
provider. Five gates stand in front of it in ascending cost order — both
modules on, ten-minute duration floor, a hard count of four a day in the
user's own timezone, an input hash over the deterministic evidence, and the
token ledger inside the shared status chokepoint. Each refusal returns a
status rather than throwing, because retrying against a ceiling that does not
move until midnight is an unbounded loop.
The detail route only reads: a workout with no row serves null and renders no
card, which is every workout that predates this and every re-synced one. An
undecryptable paragraph degrades to no card rather than failing the page.
Today gains two additive-nullable digest fields. `justIn` names the day's
newest arrival while it is still news — under three hours old, after which the
record is simply current rather than new. `reactionLine` carries a single
generated sentence about that arrival and replaces the hero's standing lead for
the rest of the local day, never appending a second paragraph, so the hero stays
one lead line tall and nothing below it shifts.
Nothing here polls. The open dashboard picks the change up on the cadence it
already runs — a state change, not a notification.
The generated sentence is bounded before it is written: the arrival spine's
unique row per kind per local day IS the throttle, the worker re-checks the
same claim before spending, and the reservation is reconciled on every exit
including each failure path. Without a provider, without consent, or against an
exhausted budget the row stays line-less and the surface falls back to the
deterministic lead — the chip and the provisional-to-final flip are unaffected.
The chip's time string is formatted client-side after mount; `justIn.at`
crosses the wire as an ISO instant so the server never renders a local
wall-clock time the browser would disagree with.
Status cards and derived-score sheets read one way: they state a verdict and
end there. The metric pages already carried the hand-off; the score sheets
passed neither an opener nor a scope, so they painted no action at all.
- Score sheets (sleep / readiness / recovery / stress / strain) gain the same
auto-sent opener the metric pages use, each scoped to the inputs that drive
the composite rather than to a block it has no equivalent of.
- Workout detail's coach launch carries the workout itself. The chat request
gains an optional workoutId; on the FIRST turn the route narrows by
{ id, userId } and pins ONE bounded evidence section onto the snapshot.
Later turns reuse the pinned snapshot, so per-turn work stays constant in
conversation length.
- /coach?workout=<id> covers the full-page and maximize paths.
The workout block deliberately does not take the fenced transport the stored-
document path takes: a workout row is the user's own sensor record, and the
projection admits no free text. That is enforced, not assumed — sport_type is
a TEXT column, so it is re-asserted against the closed sport union, metadata
is excluded apart from its numeric zone durations read through a Zod slice,
and a recursive guard throws on any non-numeric leaf.
Own-history sport averages move to src/lib/workouts/sport-context.ts so the
narrative and the detail page cannot quote different figures.
A step-up elevation minted from the account password satisfied the fresh-factor
routes. That is a second-factor bypass: a stolen token plus a known password
could rotate the recovery codes — which take no factor in the body — and then
spend one of them to disable the second factor outright. The web has never
allowed that chain, because a password login does not stamp mfaVerifiedAt.
The method is now an authorisation input. Only totp, webauthn, and passkey
satisfy a fresh-factor gate, which is exactly the set of ceremonies the web
stamps a session for; password reaches what a plain cookie session reaches and
stops. The mint gains TOTP and security-key arms so a TOTP-only account can
still manage its factor natively, and the response says which reach it bought.
The gate also returns a discriminated context. session.id meant a session row on
one arm and a token row on the other, and the disable route passed the token id
to a session-scoped query — excluding nothing, so it deleted every browser
session and revoked the caller's own device login. The transport is now in the
type and the compiler refuses the confusion.
Redemption splits into validate-then-commit so a 429, a 422, or a wrong code no
longer burns a proof against a five-per-fifteen-minute mint ceiling. The claim
is UPDATE ... RETURNING, so the statement that decides is the one that reports.
The mint is transactional behind a partial unique index. Sign-out-everywhere and
both password-reset paths clear elevations. The status read drops to plain
requireAuth — it carries no credential material — and every mutation stays gated.
The batch route now also resolves the user's timezone and module map through
the arrival seam, so a raw call count on user.findUnique no longer isolates
the read this guard is about. Filtering by the SELECT shape keeps the
once-per-batch contract pinned while letting the unrelated cached lookups
through.
Every ingest path in the product can now emit a typed, salience-classified
event into pg-boss, consumed by one worker that claims a durable per-day
reaction marker and fans out to the reaction surfaces.
The recency classifier runs at the seam, before anything is enqueued, so a
mass backfill — a multi-year Apple Health export, a provider re-sync, a
30-day catch-up — emits nothing at all. Non-salient writes are annotated and
dropped.
The worker makes no provider call by construction: it imports no provider
module, writes only markers, and enqueues nothing that is not budget-gated
downstream. Business refusals return a status rather than throwing, so a
refusal is never retried against a ceiling that will not move until the local
day rolls over.
Seams: sleep (one hook, inherited by all seven transports), workouts (the
batch route, the four provider syncs, the export importer), weight and blood
pressure (both measurement routes), labs (manual, OCR commit, document fact
commit).
The provider workout syncs could not previously tell a created row from an
updated one, so a re-sync of a recent session would have re-fired on every
poll; they now recover the distinction from the row the upsert already
returns.
Reaction lines are AES-256-GCM at rest, following the InsightNarrative
precedent, and the column is registered for key rotation. Markers are pruned
after 14 days by a daily maintenance job.
The three unit suites that stubbed `requireCookieAuth` / `requireFreshMfa`
directly now stub `requireMfaManagementAuth`, and the password-change suite
stubs the elevation revocation the route gained. Adds the unit checks that need
no database: the elevation TTL is pinned to the cookie path's step-up window so
the two cannot drift apart, the minted value is a prefixed CSPRNG secret whose
plaintext never reaches the row, and a value carrying another credential's
prefix is refused without costing a query.
Second-factor management has been cookie-only since v1.23. The gate is right:
a Bearer token is a credential whose provenance the server cannot see, and
tearing down a second factor must not be reachable from the weaker of an
interactive login and a value pasted into a script. What was missing was never
Bearer access to those routes — it was a way to say, over a transport with no
session row, that the human holding this device just re-proved a factor.
An elevation is that proof. It is minted only against a re-proved account
password or primary passkey, bound to the exact token that re-proved, single-use
via a conditional UPDATE, five-minute-lived to match the cookie path's step-up
window, and stored hashed. A stolen token mints nothing; a second token cannot
redeem another's elevation; a password change drops every one the account holds.
requireMfaManagementAuth is the one gate the management routes share. On a
cookie session it delegates to the original helpers unchanged, so the web flow
runs the code it always did. requireAdmin stays cookie-only and out of reach.
