Bundle of small reconcile fixes from the W10 QA round:
- Switch tap-target padding -12 px -> -13 px closes the 1.6 px vertical short-fall to spec-strict WCAG 2.5.5 (design M1).
- animate-pulse skeleton sites in daily-briefing, trend-annotation and doctor-report dialog now carry motion-reduce:animate-none (design M2).
- Doctor-report unavailable rows render with text-muted-foreground instead of line-through so the visual reads as 'unavailable' rather than 'deleted'; the italic hint line below still carries the semantic (design M4).
- WelcomeCarousel scrollIntoView now reads scrollBehaviorForUser from src/lib/motion so all four advertised call-sites share the helper (simplifier L-1).
- Coach replay-injection audit row renamed audit.coach.replay-injection -> insights.coach.replay_injection to match the <surface>.<verb> convention across the audit ledger (simplifier L-2).
- /api/integrations/withings/resume drops the unused request param (the handler reads neither body nor headers; requireAuth scopes the call) (simplifier M-4).
- verifyRegistration body gets the same Zod boundary narrow W13 L-3 added to verifyAuthentication; SimpleWebAuthn still owns cryptographic validation (senior-dev L-1).
v1.4.43 W13 M-3 — `detectRefusal` runs only on the inbound
`message` each turn. `priorTurns` are loaded straight from
`coach_messages.encryptedContent` and concatenated into the
`userPrompt` transcript every reply. An injection that slipped
past the regex bank on a previous turn was re-entering the prompt
verbatim on every subsequent turn, so the model saw it on every
reply — false-negative amplification.
Re-run `detectRefusal` against each user-turn re-loaded from DB
before building the transcript. On a hit, short-circuit the SSE
with a refusal AND emit an `audit.coach.replay-injection` row so
operators have a durable signal. The audit row carries the
conversation id, turn index, and matched reason — never the
message content, so the bypass payload doesn't survive into the
audit ledger.
When the model emits only a `---KEYVALUES---` block with no leading
prose (or a malformed block missing the closing marker), the
post-strip prose is empty. The previous fallback chained back to
`rawReply`, surfacing raw sentinel markers to the user. Replace with
a structured `coach.provider.empty` error frame so the UI renders
the localised provider-error copy instead of leaking the markers.
Add a regression integration test pinning that the streamed body
never contains `---KEYVALUES---` for a sentinel-only reply, and that
no assistant message is persisted in this branch.
Closes Code-H1.

Add a text-marker sentinel parser (`---KEYVALUES---` … `---END---`)
that strips the Coach's evidence block out of the prose before it
streams to the client, validates each line against a Zod schema, and
attaches the parsed entries to `provenance.keyValues`. The persisted
envelope round-trips so the disclosure renders on conversation
reload. Hard-capped at 8 lines and 1 KB to guard against
prompt-injection padding; malformed blocks log a wide-event and pass
the prose through unchanged.

The route gates on requireAuth (cookie or bearer), enforces the daily
token budget, runs the prompt-injection / off-topic refusal scanner,
and only then walks the user's provider chain.
The conversation is created via withIdempotency() when no
conversationId is supplied, so a retry under the same Idempotency-Key
replays the original assistant reply rather than spinning up a second
thread. Existing-thread turns skip the wrap.
Replies stream as SSE: one "token" frame per word-sized chunk, then a
"provenance" frame describing the windows + metrics the assistant
could see, then a "done" frame carrying the persisted message id.
Provider failure cascades to a single "error" frame and the assistant
message is never persisted. Conversation history is capped at 20 turns
in the prompt window via a synthetic summary placeholder so cost stays
bounded.
`buildCoachSnapshot()` reuses the analytics features pipeline so the
Coach narrates the same numbers the dashboard tiles render.
`getCoachSystemPrompt()` extends the strict-insight ground rules with
conversational framing while keeping the zero-hallucination rule.
5 integration tests pin the round-trip, refusal short-circuit, budget
429, foreign-conversation 404, and validation 422 paths against the
postgres testcontainer.
