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.
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 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 native pen list renders these two as its headline and subhead. The
server held neither, so a container registered on the web could not be
shown there without fabricating an empty card, and the client kept its
own copy locally with no back-fill possible.
Both columns are additive and nullable (migration 0255). Every existing
row is truthfully NULL — the values were never collected, and a plain
supply row such as a blister pack or a bottle has no use for either.
Strength stays free text rather than a parsed number + unit: pens state
it per dose, per ml, or per cartridge depending on the product, and
forcing a numeric split would lose which of the three was printed.
On PATCH an omitted field leaves the stored value untouched, the same
rule notes already followed, so a client that does not know the fields
cannot blank what another populated; an explicit null still clears. The
web add-container form collects both for a PEN, so the columns do not
ship empty forever.
Three surfaces where the words no longer matched the code, plus the missing
web control for a preference the server already honours.
Delete confirmations. Four dialogs promised permanence on surfaces that
render an Undo: the measurements and mood bulk bodies, the lab-result body,
and the illness-episode body (which said "cannot be undone" sixty lines
below the code that fires the Undo toast). All four now use the same
sentence the single-row measurement and mood dialogs already used. A sweep
of every other confirmation in the tree found the rest accurate — the
biomarker cascade, the mood-tag purge, and the account purge keep their
warning because those deletes really are unrecoverable.
Sleep debt. v1.19.0 replaced the summed shortfall with a running balance
that credits catch-up sleep; the labels still described the old sum, so the
word contradicted the number for anyone who slept in after a short night.
Corrected in all six locales, plus the places the old semantics had
propagated: the Coach system prompt, the OpenAPI field descriptions the
native client reads, and four module docblocks.
Glucose reference band. `hasDiabetes` selects the tighter reference band and
grounds the Coach, but no web surface set it — a web-only account was pinned
to the non-diabetic scale with no way out. The control goes on Targets,
above the per-metric editor, because it answers the same question that page
answers and the two are ordered: it picks the default band, an override
below beats it. The copy says what it is — a reference band, not a
diagnosis, never inferred from a reading, no clinical action taken on it.
The passkey list was reported as always reading "never used". It does not
reproduce: the column is selected by the list route and stamped on every
verified assertion, both since v1.23.0. Pinned with tests on both halves so
the contract cannot quietly regress.
Both metrics exist in the record but the summary route emitted neither,
so a native client could render every home-screen tile except those two.
Mood reads the canonical daily series (`buildMoodDailySeries`) — the same
rollup-backed aggregation the web mood analytics and the dashboard
snapshot render — and emits the newest day's score with a trailing
seven-day sparkline. BMI comes from `computeBmi`, the one implementation
the web vitals dashboard already renders through the derived-metric
dispatch; the route resolves the figure so no client re-derives weight
over height squared.
Mood gates on the mood module through a synthetic `MOOD_ENTRY` key, the
same route `NUTRIENT_WATER` takes, because mood is not a measurement
type; without the join the card would ship past a disabled module. BMI
belongs to no module and rides through with the other core vitals.
The BMI card is omitted rather than emitted empty when the profile has no
height or no weight in the window: the card shape carries no honest
"unknown" state, and a null value would read as a logging gap rather than
a missing profile field.
The layout PUT preserved chartOverlayPrefs, selectedScoreRings and
heroRingOrder when a client omitted them, but the top-level
comparisonBaseline was not in that merge. serializeDashboardLayout clamps
a missing baseline to "none", so a layout save from a client that does
not know the field — the native client treats it as web-only and never
sends it — silently reset the comparison the user had picked on the web.
No error, no audit row.
Replace the hand-maintained three-field merge with an explicit
disposition map over every top-level layout field. The map is declared
`satisfies Record<keyof DashboardLayout, ...>`, so adding a layout field
without deciding replace-or-preserve fails typecheck; the preserve set
and the merge are derived from it rather than restated. The stored-layout
read is skipped when the client sent the full set.
Also catalogue the four clinical signals the native client pins — grip
strength, pain NRS, waist circumference, waist-to-height. They reached
the route as unknown ids, were filtered out ahead of Zod, and vanished
from the persisted layout, so a tile placement was lost on every save.
They join the iOS-only set because the web dashboard has no render path
for them; their charts live on the insights sub-pages. Raise the widget
array cap to 50 to clear the now-42-id catalogue.
Also closes the device list's exposure of the same value, refuses a
cross-device refresh rotation, replaces a vacuous expiry test with one
that fails when the check is removed, and asserts the Nightscout host
guard at save time rather than relying on the probe's placement.
The settings mount fires an idempotent consent heal so an account that
predates the gate does not fall into the no-key state. It looked only for
an active receipt, so a deliberate withdrawal — which sets revokedAt —
read the same as never having consented, and the next visit to the AI
settings granted again, writing an audit row for an act the user never
performed. GDPR Art. 7 (3) puts withdrawal on the same footing as the
grant; one undone by a page load is not a withdrawal.
The mint now distinguishes the two callers. The mount heal grants only to
an account with no consent history at all and leaves a revocation
standing; switching document auto-read on is the consent act itself and
may supersede an earlier revocation. The revocation is re-checked inside
the transaction so a withdrawal landing mid-mint is not overwritten.
The revoke endpoint has existed since v1.4.40 but only the native client
called it: on the web, consent could be given and never taken back. The
AI settings now carry the standing decision and the control that changes
it, in all six languages.
Egress was already correct — the client fetches through safeFetch with
requirePublicHost pinned off the user's opt-in, manual redirects and a
timeout — but the check on the value we STORE was only a side effect of
the live probe the connect route happens to run first. That makes the
guard contingent on the probe's placement rather than on the input.
Run isPublicUrl at input time, gated on the same self-hoster opt-in, so
the URL that gets encrypted onto the row is the URL that was validated.
Cover the alt-notation classes the helper knows about; each case asserts
the probe was never reached, which is what distinguishes the input-time
refusal from the fetch-time one.
The per-document summary job is enqueued at upload time and no-ops while the
documentsAutoAiRead opt-in is OFF. Nothing ever re-enqueued it, so the switch
only applied to documents uploaded AFTER the flip — a user who filled the vault
first and opted in later had documents that would never be read, and the
setting looked inert.
A genuine OFF->ON transition now schedules one bounded catch-up pass over the
user's un-summarised documents. It grants nothing of its own: it only enqueues
the ordinary summary job, which still re-reads the opt-in, re-asserts the
per-document egress consent and reserves the daily token budget. The pass
itself re-reads the opt-in first, so a toggle flipped back OFF before it runs
egresses nothing.
Bounded by an id-cursor walk capped at 200 documents per pass (a summary is a
provider call, unlike the local-compute thumbnail backfill). Idempotent at four
levels: the trigger fires only on a real transition, the per-user singleton
collapses a double toggle, the candidate set excludes summarised documents, and
the summary job skips one that already has a summary.
Opening a document said "the summary is being prepared" and kept saying it.
The view had one fallback for a null summary column and used it for every
outcome: a document nobody ever enqueued, a missing vision provider, a spent
budget, a withdrawn consent, an unreadable file, a provider error, and a
summary the outbound screen withheld all rendered as work in progress.
The common case is not the screen. The background job is enqueued at exactly
one place — a fresh upload with the auto-read opt-in already on — and no
backfill reaches anything else. Every document uploaded before the toggle went
on has a null column no job will ever fill, and the view promised all of them a
summary that was never coming.
Record the outcome as `summary_state` (migration 0254, additive, defaults to
NONE which is truthful for every existing row) and branch on it. Only PENDING,
set when a job genuinely exists, may claim generation is running. NONE,
WITHHELD and UNAVAILABLE each say what happened and offer to generate one.
The withhold keeps its rule and loses its dead end. Blocked prose is still
never shown and never stored — only the fact of the refusal is kept, and it is
no longer terminal, so asking again re-runs the gauntlet. That was the original
intent; leaving the column null defeated it, because null read as "generating"
and the guard meant nothing would ever overwrite it.
The on-demand summary now persists what it produces. It is the only repair path
for the documents the job never ran for, and re-deriving the same paragraph on
every open costs a provider call for nothing. Generation is still only ever a
click — nothing runs because a view rendered. Transcription stays session-only.
Also drop the "read by AI" line from the detail footer.
The Today hero stayed on its all-clear line while a dose was actually due:
the dose-window item only fired once the slot was already overdue, so a
dose the user could take right now produced no rail item at all. Emit the
item from the moment the dose becomes takeable — the on-time window's lead
plus the early grace, the same instant logging it starts crediting the
slot — and give the two faces distinct wording and status: a due dose reads
calm and informational, an overdue one keeps the warning. A settled day
still emits nothing, and a cached block whose anchor has since passed keeps
rendering neither face. Push reminders are untouched; they still fire only
on overdue.
The briefing grounding gate discarded the whole block over one number it
could not verify, and it could not verify plenty of legitimate ones: the
allow-set was a hand-maintained list of feature blocks that had already
drifted from the prompt three times, and still omitted medication
compliance, the context counters, the correlation coefficients, every
coverage object and the comparison snapshot — all of which the prompt hands
the model verbatim. Derive the allow-set by walking the prompt payload
instead, so grounded means exactly what it says: a figure the server gave
the model. A fabricated number still matches nothing.
Fix the disposal to match. A content-failed retry left a hole while a
transport-failed one fell back to the previous cached briefing, though in
both cases the rejected text is discarded and the previous briefing passed
this same gate when it was written. Fall back on both paths, and only
report the briefing as withheld when there is genuinely nothing to show.
The on-demand route had no fallback at all; it now mirrors the background
generator that writes the same cached payload.
The rhythm, average-sleep and chronotype cards on /insights/sleep share
a single ["sleep-rhythm"] read, and each rendered its own copy of the
same failure sentence — so one failed read painted the identical notice
three times, none of them offering a way to try again.
The page owns the shared state now: one notice with a retry in place of
the card row. The cards keep their loading and empty handling and drop
the duplicated error branch.
Importing the plural helper directly from the dashboard trend tile cost
~78 KB gz across the route chunks: the module is tiny, but a new edge
from a widely-instantiated component gets duplicated into every chunk
that contains it rather than hoisted. The provider is already in every
chunk, so expose a plural-aware tCount() there and let components call
that instead. Total client JS goes back under budget.
Also fix the two tests the honest-loading-state change invalidated: the
mental-wellbeing landing tests seeded a never-resolving read and so now
render skeletons rather than instrument cards, and the achievements page
needs a router in scope for its module-gate redirect.
"No data yet" is a claim about the user's record. Making it when the
read failed states something false about their health history.
The mental-wellbeing surface was the one that mattered: the assessment
history read dropped isError entirely, so a failure left both
instrument cards showing "not taken yet" and the detail sheet showing
an empty trend. Someone with months of screening results was told, on
a mental-health surface, that the results did not exist. It now tells
loading, failed and genuinely empty apart, with a retry on the failure.
Also swept:
- the workouts insights page read isEmpty but not isError, so a failed
list read fell through every branch to null and painted a titled
shell with nothing in it;
- the micronutrients card (not in the original list) rendered its "no
nutrient data" empty state on a failed read, while its sibling
hydration card already used the shared error card;
- the medication detail page and the custom-metric values list showed
an honest error with no way out. Both keep retry: false — right for
a deleted row, wrong for a transient failure — and gain a
user-initiated retry instead, which cannot storm;
- /achievements rendered a blank page on a direct hit with the module
disabled. It now bounces to /insights like every other gated page.
The achievements query error branch, the custom-metric error branch and
the chronotype notice were already correct and are left alone.
Four locales received English on surfaces whose translations were
already complete, because the resolving code was a de/en binary.
- Medication reminder push and the Telegram inline-keyboard labels
admitted only de/en, so es/fr/it/pl got the English template on every
channel. Route the resolver through a shared coerceLocale().
- The Coach's trailing "reply now in X" clause said English for any
non-German locale, overriding the correct system-prompt directive.
Read the language name from a shared map instead.
- Coach refusal copy was a de/en constant pair, answering four locales
in English at the one turn the Coach is declining to help. Move the
copy into the bundles; the EN/DE constants now derive from them.
- The sleep-stage chart formatted axis ticks as en-US for four locales;
the cycle calendar and the device-score tile followed the *browser*
locale rather than the app locale.
- Three components carried a byte-identical duration formatter that
branched on German. Lift it to one key-driven helper.
Polish needs a third plural tier: 2-4 takes a "few" form a two-form
scheme cannot express, so "2 godzin temu" read as "2 of-hours ago".
Add a pluralKey() helper driven by Intl.PluralRules and a Few tier to
the relative-time and stale-hint keys. The five locales whose rules
have no "few" category resolve exactly as before by construction, and
their Few values mirror Other. Teach the reverse-coverage guard to
expand a pluralKey() base into its three tiers.
enforceBudget and recordSpend have no callers left. Both defects they
carried recurred every time a surface copied them: a TOCTOU window
between the read and the bump, and a cap parameter defaulting to the
operator ceiling so an omitted argument rationed a self-hoster paying
for their own key. Deleting them means a future surface cannot reach
for the older, simpler-looking helper and reintroduce either.
getDailyTokenSpend goes with them — it existed to feed the read half.
The ledger-poisoning clamps recordSpend carried (NaN, negative,
fractional token counts) move to reserveBudget, where the property now
lives. Refresh the doc comments that still narrated the old flow.
The route used the enforceBudget + recordSpend read-then-write pair and
passed no cap, so every call measured against the operator ceiling — a
self-hoster on their own key was rationed by the operator's bill while
paying for their own usage. It also left the TOCTOU window the rest of
the codebase closed: concurrent calls could each read a sub-cap total
and all proceed.
Move the gate after the chain resolves and reserve atomically against
resolveDailyCap(chain), matching runStatusCompletion and the document
paths. Reconcile on every exit: the provider's reported count on a
completed call, a full refund when nothing was generated.
Pin the four guarantees at the new chokepoint and at both call sites: spend
lands on the ledger, over-cap is refused before any egress, a BYOK chain is
measured against the user-plan ceiling rather than the operator's, and a
failed call refunds in full. Also pin the ordering the consent gate depends
on — a consent-blocked user is never charged.
The status tier funnels every generation through runStatusCompletion, which
reserves against the day's ledger before egress and reconciles after. The
comprehensive briefing did not: the shared generator and the on-demand
POST /api/insights/generate route both called the provider chain directly, so
none of that spend reached coach_usage and no daily ceiling applied to it.
Route every briefing provider call — first pass, JSON-shape retry,
grounding-correction retry, and the daily paragraph re-roll — through one
chokepoint that reuses reserveBudget / reconcileSpend and resolveDailyCap. The
reservation lands after the consent gate, so a consent-blocked user is never
charged, and a failed or timed-out call is refunded in full.
Over-cap is a typed skipped outcome for the off-request generator (no upstream
fault to retry against, so no failure marker and no retry enqueue) and a 429
for the on-demand route.
Each case fails on the pre-fix code: the rollup tests on an unaligned
recompute window, the batch tests on the older stats: snapshot winning,
and the resting test on a series that stops at the fold horizon.
Two entries carrying the same stats: key in one batch both miss the
existing-row probe, so the overwrite branch never runs, both land in the
bulk insert, and skipDuplicates keeps whichever the unique index saw
first. The older snapshot of a per-day cumulative total or of a filling
ten-minute heart-rate bucket therefore won and the newer, larger figure
was dropped silently — both entries reported inserted, the counters
still summed, and the client checkpointed past both.
stats: rows carry overwrite semantics by contract, so within one batch
the last entry for a key is the authoritative one. Resolve it up front
and report the superseded earlier entries as duplicate with a
superseded_in_batch reason, a status the client already checkpoints
past.
The Coach SNAPSHOT was spliced into the prompt bare. Its JSON leaves are not
all server-computed: lab analyte, panel and unit names are transcribed by a
model out of an uploaded PDF and stored verbatim as the biomarker name, so a
hostile document chooses those strings. The about-me block has been fenced
since v1.16.1; extend the same pattern rather than adding per-field escapes.
- Move the fence markers and the wrapping primitive into a shared data-fence
module. Content is scrubbed against every known marker, not just its own
pair, so text in one block cannot forge another block's boundary.
- Fence the SNAPSHOT with an explicit data/instruction frame.
- Fence the OCR text handed to the document extractor; the previous
'OCR TEXT:' label was a label, not a boundary.
- Sanitise analyte, panel and unit at the labs source, which feeds both the
snapshot prompt and the labs_read tool result, and the medication label in
the adherence storyline.
- Capture a ---REMEMBER--- sentinel as proposed rather than active. It was
the only model-driven write with no confirm step, and the reminder recall
block fed it back into every later turn. Proposed reminders are already
excluded from that block and already carry a confirm control.
The status-provider suite drives the real budget module against an
in-memory stand-in for the day's usage row, so it exercises the atomic
reserve/reconcile path rather than asserting a mock was called: spend
lands on the ledger, an exhausted day is refused before any egress, a
failed generation is refunded, and a chain on the user's own key is
measured against the user-plan ceiling rather than the operator's.
The snapshot suite walks a 60-turn conversation and pins the full
snapshot to exactly two turns — the first and the elision crossing —
including the case where a lost reply shifts the turn parity.
The provider chokepoint every status and reference generator funnels
through ran with no budget accounting at all. Nine generator families
egressed behind it — the specialised status cards, the generic metric
cards, biomarker cards, the batched assessment, the derived scores, the
period narrative, and the off-request Coach memory workers (rolling
summary, fact extraction, plan proposals) — and none of that spend landed
on the daily ledger or met any ceiling. On an operator-key account it was
unmetered operator spend.
Reserve and reconcile around the provider call, using the same atomic
upsert the Coach and document paths use. The ceiling follows the cost
owner: a chain whose primary is the operator's own credential draws the
operator ceiling, everything else draws the user-plan ceiling, so a
self-hoster on their own key is never rationed by the operator's bill.
The status enqueue keyed its de-dupe singleton on (user, metric, locale).
The locale on a status read is client-chosen, so each of the six
supported locales opened its own slot and one legitimate generation pass
could be multiplied into six. Key on (user, metric) and carry the locale
in the payload instead.
The Coach re-shipped the full snapshot on every turn past the history
cap, not just the turn that crosses it, so a long conversation paid the
per-turn snapshot cost the snapshot-once model exists to remove. Re-ground
on the crossing only, tested as a narrow window rather than an equality
because a turn advances the count by one or two depending on whether the
reply persisted.
Give /api/ai/test a daily ceiling and a ledger entry. Its burst bucket
bounded rate but nothing cumulative, and with an empty body it resolves
the same chain generation uses — which can be the operator's credential.
Correct the memory-refresh worker comment, which asserted a budget check
inside the chokepoint that did not exist.
The briefing gate grades numbers only, and only the paragraph, signals and
key-findings blocks -- so a digit-free risk assertion with a dose suggestion
attached passed it untouched, and recommendations and summary were not graded
at all. Screen every readable prose field against the insights contracts.
A safety violation cannot be surgically stripped the way an ungrounded number
can: the offending sentence may sit in any field, and deleting one would leave
the rest referring to it. So the background generator fails the whole run and
persists nothing, leaving the previous cached payload in place, while the
user-initiated route returns an explicit error for the same reason.
The summary is model prose about the document and is contractually
descriptive-only, but it was returned to the browser verbatim with no guard.
Screen it against the insights contracts and let each caller apply its own
policy: the on-demand route replaces the text with a short honest statement
because a user is waiting on it, while the background job persists nothing --
its updateMany is guarded on a null summary, so a stored refusal would stamp
the document permanently with no path to regenerate.
Transcription stays unscreened by construction. It reproduces the user's own
document verbatim; a discharge letter that says to increase a dose is the
prescriber's instruction, and censoring it would delete the user's own record
from their own view. Locale is required on the summary input type and absent
from the transcription input so a caller cannot silently fall back to the
English banks.
The outbound safety screen ran on the Coach only. A dose-change imperative or
a fabricated clinical risk score written onto a per-metric, biomarker or
derived-score status card persisted as that day's cached assessment, while the
identical sentence in the Coach was caught and replaced -- the only transform
between provider and persistence was whitespace normalisation.
Move the pattern banks into a shared screen that takes the reader's locale.
The old signature took no locale, so the dose-refusal and risk-score contracts
had no enforcement for fr/es/it/pl even though the ground rules ship in all six
contract files. Banks now cover all six locales and each screen runs the
reader's bank plus English, since a provider often answers in English
regardless of the language directive.
Status cards withhold on a trip: serve the deterministic stub and persist no
model text. Nobody waits on a background-generated card, and persisting a
refusal would pin it to the card for the day.
The restore target came from the encrypted payload's own userId field
while the audit entry recorded the backup row's userId. A file declaring
a different account would therefore have been written into that account,
with the trail naming the one the operator selected.
Both values are in hand at that point, so compare them and refuse on
mismatch, recording both ids. Adds the first test coverage for this
route; the mismatch case fails without the guard.
Also correct the CLAUDE.md claim that every API route wraps apiHandler -
the three MCP OAuth routes deliberately use withBackgroundEvent so they
can return RFC-format error bodies, and carry the same protections by
hand.
