Nothing warms this queue and no read path triggers it, so an unregistered name
fails open in the worst way: every send resolves, every job vanishes, and the
symptom is indistinguishable from the surface's honest empty state.
The paragraph is model output. Rendering it as markup would be an XSS surface,
and this project ships no markdown library so the question stays closed — the
test is what keeps that from being treated as a formatting decision.
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.
The one-paragraph-per-workout claim is a unique index, the cascade is an FK,
and the daily-cap window is a SQL fact — a mocked upsert reports success for
all three regardless.
The push endpoint host is user-controlled — the browser supplies it at
subscribe time. `isPublicUrl` guards it at subscribe time and again before each
dial, but it is a literal input-time check and cannot see a DNS rebind between
the accept and the connect; with a short-TTL record the dial reaches the pod's
private network.
`web-push`'s `sendNotification` dials with its own internal `https.request`,
which bypassed `safeFetch` and therefore the connect-time pin entirely. Both
senders now sign and encrypt through `generateRequestDetails` — identical VAPID
handling and payload encryption — and dial through `safeFetch` with
`requirePublicHost`. Non-2xx is re-shaped as the `{ statusCode }` rejection the
existing classification already understands, so the 410/404 expiry reap and the
transient/permanent split are unchanged.
This is the last user-controlled-host egress that was not behind the pinned
dispatcher (issue #217).
The contract now names which factors satisfy the fresh-factor routes and which
do not, carries `satisfiesFreshFactor` on the mint response so a client can pick
the ceremony before spending a proof, and describes the options endpoint's two
ceremony kinds. The second-factor status read is documented as plain
authentication — it carries no credential material, so it needs no elevation.
The projection's central claim was carried by a comment. It is now walked
before it is returned: any non-numeric leaf at any depth throws, and the only
two string leaves are allowlisted by shape — the sport type against the schema
enum itself, and the day key against its format.
This matters because sport_type is a TEXT column whose API write path is
enum-constrained but whose backup-restore path accepts any non-empty string, so
a restored row can carry arbitrary text. It is re-asserted at the projection
boundary rather than trusted from the column. The heart-rate provenance string
is dropped rather than allowlisted, and route geometry stays consumed-not-carried
— it yields one number, and location history may not ride a prompt.
Own-history rows now collapse cross-source twins through the canonical picker,
as the detail page's comparison already did; a session recorded by two paired
watches was inflating the sample size and biasing every median.
The tiered rollup read emits minValue/maxValue; readLiveDaily omitted them, so
on a rollup-cold account or a coverage miss the chart silently dropped the
min/max spread band for the same underlying data — contradicting the file's own
byte-for-byte parity claim. The live aggregate now selects MIN/MAX alongside the
average.
useSendCoachMessage never aborted its in-flight reader on unmount. The drawer
works around that through handleOpenChange, but the full-page /coach surface
passes no registerReset, so navigating away mid-stream left the SSE loop alive:
the provider kept generating and billing, and trailing setState fired on an
unmounted component.
Switching conversations reset every piece of local state except the send state,
so the previous thread's last assistant or error bubble rendered appended to the
newly selected thread until the next send.
The two lifecycle invariants are pinned structurally, not behaviourally — the
repo ships no renderHook. That is weaker, and the header says so; both defects
were a missing call, which is what a structural guard does catch.
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.
`createTagLinks` validates `ratedFactors` after the mood row is written. On the
bulk path the two ran as separate awaits on the base client, so an out-of-scale
rating threw once the row had already committed: the per-entry catch reported
"skipped" — the one status that promises nothing was saved — while a mood entry
with no tags or factors sat on disk. The single-entry POST has always wrapped
the pair in one transaction; the bulk twin now matches.
The test client for the transaction is a distinct object from the base client
on purpose. Sharing one identity made the atomicity assertion vacuous: a write
that escaped the transaction looked exactly like one that stayed inside it.
Three properties, each with a mutation-verified guard:
The chip and the line run on DIFFERENT clocks and must keep doing so. The chip
expires after three hours; the line stands for the rest of the local day.
Collapsing them onto one clock reads like a simplification and silently deletes
the day's read at lunchtime.
Degradation is the headline. For every reason a line can fail to exist — no
provider, no consent, an exhausted budget, a dead provider, an unusable output
— the row stays line-less, the reservation is reconciled, and the chip and the
provisional-to-final flip still work. The degraded digest is built through the
real composer rather than a hand-shaped fixture, so the assertions cannot agree
with themselves.
The server pass carries no wall-clock time. The hero paints on the SSR pass
because it is the LCP element, so a locale-formatted time inside it would differ
from the browser's — React #418. The tests render through the server snapshot,
which is exactly the pass that must stay clock-free.
The seeded end-to-end spec lands a sleep batch through the real ingest route,
writes the arrival marker, and asserts the chip and the phase flip in place on
a refetch trigger the digest hook already declares — no reload, no new cadence.
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.
The evidence block is a numbers-only server projection: zone seconds, the
workout-window heart-rate shape, route climb and a same-sport 90-day own-history
median. Free-text metadata never enters it, and the sport string is narrowed
against the closed enum first, so the payload carries no text the user did not
generate through a measured field.
The prompt composes the shared assessment base and adds the session contract:
device-attributed, own-history-comparative, effort acknowledged where the
numbers show it, and no training prescriptions of any kind. Registered in the
tone harness beside the assessment cards.
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.
Each of these was already correct in the tree and had nothing asserting it, so
a refactor would have regressed it silently.
The decrypted-snapshot LRU keys on userId, but only same-user memoisation and
scope-change recomputation were covered — dropping the userId segment would have
served one account's health snapshot to another with a green suite. The project
has shipped one cross-user cache-leak fix already; this is a repeat class.
The GlitchTip forwarder redacts path-segment secrets in the url it sends. The
query-string strip was tested; the path-segment pass was not, and that is the
one that reaches a durable external incident UI.
The Withings credentials DELETE narrows its connection-row delete to P2025 and
rethrows everything else, so a real failure can no longer null the client
credentials and report a successful disconnect while the encrypted OAuth tokens
survive. The route had no test file at all.
Its own table, cascading from the workout row, because workout deletes are
hard deletes. The paragraph is AES-256-GCM at rest and registered for key
rotation; the input hash and prompt version make a re-post of the same
session a free no-op.
The deterministic fallbacks nine metric surfaces render when no provider is
reachable carried German and English bodies only. `getLocalizedText` returned
`locale === "de" ? de : en`, so French, Spanish, Italian and Polish readers got
English — on the no-key path, an outage, a spent budget or a timeout, which is
precisely when this text is the whole assessment.
Every string now has a body per locale: the verdict leads and value sentences
of the signal-grounded composer, the per-metric labels and pointers, and the
eight no-signal floors. Selection reads the reader's locale; English stays as
the structural floor for a locale that is ever genuinely missing a body.
The bodies are written per language, not translated word-for-word. fr/es/it
replace the comparative adjective ("higher than your usual average") with a
preposition — au-dessus de / por encima de / sopra — because a comparative
would have to agree in gender with the metric noun, and the labels do not share
one. Polish restructures further: the sentence takes `wynosi`, which is
invariant for the subject's gender, and the comparison uses powyżej / poniżej
with the genitive; the labels span all three genders, so nothing that inflects
can sit in a shared template.
The tone harness grades the four locales by the same rules rather than passing
them by default: false cheer, clinical-verdict and imperative-opener vocabulary
extended to all six, the no-assessment sentinel keyed per locale instead of a
de/en binary, and a byte-identity guard that fails if any locale silently falls
back to the English text again. The value-led-opener rule was rewritten as
well — it assumed the copula sits against the figure, which under-matched its
own second locale (German "liegt aktuell bei 24") and would have missed all
four new ones.
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.
The water quick-add validated calendar realism but never the upper day bound the
batch route applies, so a far-future day was accepted and — every read filters
`day >= since` with no ceiling — became the permanent latest day on the settings
card and the dashboard tile. Hoist the bound into one shared helper both routes
use.
`mode: "add"` bounded a single request to the catalog's plausible daily max but
nothing across requests, so repeated quick-adds drove the stored total
arbitrarily high while the batch route enforced the same cap strictly. Clamp
after the increment so the write stays atomic.
Thiamin's cap sat at exactly 1000 mg while its PRI is exactly 1.0 mg, so a
microgram-read-as-milligram sample landed on precisely the cap and the `>`
comparison let it through. 500 still clears any real supplement dose.
NutrientIntakeDay was in no export path, which contradicted the schema's own
reason for denormalising the unit column. Carry it in the full backup with its
unit and source — source is part of the composite key, so without it a restore
cannot tell a manual entry from a synced day total.
The proxy's seven early exits — worker-only 503, two legacy 301s, the demo-mode
403, and the login / onboarding / MFA redirects — returned before the security
header block, so they carried no HSTS, no framing refusal and no nosniff. Factor
the transport subset into a helper and apply it on every exit. The per-route CSP
stays where it is; it is nonce-bound and only meaningful for a response with a
body.
The WebAuthn relying-party candidate list always carried http://localhost:3000,
including in production. The signed rpIdHash still pinned the real domain, so
this was never a reachable bypass, but a configured production origin has no
reason to carry it. Gate the fallback on development, keeping it when nothing is
configured so getRpId() still resolves.
ORPHAN_ENUMS was a hand-maintained literal that drifted every time
ALLOWED_CHART_TOKENS grew — eighteen allowlisted metrics had no strip entry, so
a model writing 'Your PHQ9_SCORE is elevated' leaked the raw enum into rendered
prose. Derive it from the allowlist and pin the coupling with a test.
`classifyIntakeTiming` treated `windowStart === windowEnd` as an overnight
wrap, inflating a degenerate point window into a ~30h on-time band — a dose
taken many hours late still classified `on_time` and fed a perfect-compliance
streak. Widen the point window symmetrically instead, matching the treatment
`resolveLegacyWindowBounds` already applies.
`/api/measurements/batch` never applied the entry-instant plausibility bound
its single-entry twin has carried since v1.17 W1b, so a future-dated row landed
and permanently won 'latest reading' while poisoning the rollup buckets and the
canonical picker. Skip per entry, like the range guard. The past floor stays at
1900 — a historical backfill is a legitimate shape here.
The intake CSV import had neither an upper date bound nor a rate limiter, while
running up to 1000 sequential find + create + consume iterations per call. Add
both, on the bulk twin's bucket shape and budget.
The no-signal floors were the coldest text the product renders. They run when
there is nothing to ground against, and they opened on a bare order — "Measure
blood pressure at rest and under comparable conditions", "Evaluate mood trends
over several weeks" — so the one moment the surface has nothing to say was also
the one moment it told the reader what to do.
They now open on what the surface can honestly say: no assessment is available
right now. That is the meaning-first opening for this case, and it is the only
one available, because a floor with no signal may not imply a read. What
follows describes how the measure behaves rather than ordering the reader
around. The signal-grounded lines above them are unchanged.
The prompt version bump re-fingerprints the assessments cached under the old
biomarker prompt; the per-card input hash folds the constant in, so the
regeneration is one-time and paced by the nightly warm.
Backfill immunity is proved by replay, not by a hand-picked case: a ten-year
Apple Health export (12772 writes) and a 30-day provider re-sync (58 writes)
must both emit zero events, while a fresh sleep night, workout and first
weight of the day emit exactly one each.
The provider-isolation guard walks the worker's static import graph and fails
if any provider client or resolver becomes reachable. It carries two positive
controls, so a broken entry path cannot make it pass against an empty graph.
The integration test covers what unit mocks cannot: the unique index, the
ON CONFLICT DO NOTHING claim, the losing side of ten concurrent claims, the
forward-only marker, ciphertext at rest, the delete cascade, and the
retention window.
The German prompt-injection test asserted only inside `if (decision.refuse)`,
so it stayed green whether or not the filter fired. Un-guard it, drive it from a
case table, and widen the two German patterns to cover the determiners that
walked straight past them ("saemtliche", "die", "deine").
The Oura / Polar / Fitbit token helpers cast a possibly-null `json` to the token
type on a status-only success gate. A 2xx with an empty or non-JSON body handed
callers a null they dereferenced, surfacing an unclassified TypeError instead of
a handled integration error. Narrow explicitly and classify as transient.
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.
A deterministic grader over the assembled assessment prompts and the
deterministic fallback text. No provider, no network, no database — it runs in
the normal suite in under half a second, which is the point: the live-judge
eval needs a key and can only advise, so the regressions that actually shipped
need a check that can block.
Three classes are blocking. A surface stops leading with meaning (it drops the
shared opening contract, or its user prompt loses the meaning-first
instruction). A locale collapses (fr/es/it/pl fall back to the German body or
lose the reply-language directive). A prompt reintroduces a value-first
instruction — matched with negation handling, since the shared prompts quote
that failure mode in order to ban it.
The deterministic fallbacks are graded on the same axis, including the
asymmetry that matters: a signal with no baseline supports no confident read,
so that one line honestly opens on the value. Pinning it stops a future
"always lead with meaning" edit from pushing the surface into claiming
something the data does not support.
A coverage guard fails when an assessment prompt module has no harness entry,
so the next surface cannot stay uncovered the way the biomarker card did.
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.
The per-biomarker assessment was the last surface in the family building its
prompt inline: a five-line scaffold that skipped the base system prompt, took
no opener hint, and instructed the model to "state the current value" — so the
one card where a bare number reads most like a verdict was value-first by
instruction while every sibling had moved to meaning-first.
It now composes exactly as the seven bespoke cards do. The new prompt module
carries a METRIC section that states the one thing this card needs and the
others do not: its snapshot has no signal block, so the read comes from the
pre-computed range placement plus the direction across draws.
Also point both archetype-driven cards at a registered budget. The generic
metric card and the biomarker card each carried temperature/maxTokens inline
at 0.45/1000, so the registry that documents every surface's ceiling was
silently wrong about the two widest assessment surfaces.
The single-marker no-key fallback replaces the multi-metric overview tip the
card used to render — text about watching several metrics at once, on a card
showing one lab value.
Adds the structural guard that freezes the exact route set an elevation can
unlock, plus the behavioural suite that drives each threat case against a real
Postgres: a token alone mints nothing, an elevation minted for one token is
refused for another (same account included), a second redemption fails, a
concurrent redemption lets exactly one winner through, an expired one is
refused, an elevation never reaches requireAdmin, a wrong password is throttled
and audited without saying what was wrong, and the cookie flow is untouched.
The OpenAPI registry carries both new routes and names the accepting set in
prose, so the client implements against the contract rather than against a
description of it.
Signing every other device out, revoking a single session, revoking a
trusted device and revoking them all each fired on a single tap. None is
undoable — the other devices simply have to sign in again, and a revoked
trusted device asks for its second factor next time — while every other
destructive surface in the app confirms first. On a shared screen a
mis-tap is a support call.
A sweep of the rest of the tree found two more hard deletes with neither
a confirmation nor an undo: a Coach reminder and a travel entry. Both now
confirm. Deleting a document deliberately does not: it soft-deletes and
offers an undo, which covers the mis-tap.
The four controls share one ConfirmButton rather than four copies of the
dialog, so the next destructive control gets the confirmation by using
it instead of by someone remembering. Copy is per control and states the
actual consequence — no claim of more finality than is true.
The widget catalogue grew to 42 ids, so the snapshot round-trip count
follows. The mood card's unit key carries "/5" rather than an empty
string — the locale-integrity guard forbids empty values, and the scale
is the honest thing to print next to a 1-to-5 score. It joins the
identical-across-locales allowlist alongside the other unit notations.
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.
