Replace the collapsed bottom-of-card "Chat about this document" outline
button with a neutral, ghost Coach icon pinned to the top-right of the
document detail-sheet header, mirroring the Insights ask-coach affordance.
The icon uses the muted-foreground token only — never the primary/FAB
gradient — and opens a document-scoped chat drawer.
Present the chat in the Coach chat drawer chrome (right-side sheet on
desktop, bottom sheet on phones; same width caps; close-only, no maximize
or conversations rail) with a quiet "Chatting about: <document>" scope
badge. The drawer reuses the existing pure conversation body and the
existing client hooks, so it still posts /api/documents/inbound/[id]/chat
verbatim: no tools, no health snapshot, fenced document, inbound/replay
refusal, outbound screen, numeric grounding, consent + budget + per-user
rate bucket, indexed-only, plain-text render — the route is untouched.
Thread isolation is unchanged (the general Coach filters documentId: null;
the document route always scopes { documentId: id }).
Add a small reusable headerAction slot to ResponsiveSheet for the header
icon. Retire the DocumentChatPanel container and the AI-section chatSlot;
keep the pure DocumentChatConversation body and documentChatErrorKey.

e2e/
End-to-end browser tests. Playwright 1.60 drives a production build of the app against a real PostgreSQL, with @axe-core/playwright for accessibility assertions. This is the heaviest test tier; CI runs it on every PR, and locally it is worth running when a change touches a UI flow.
Running
pnpm e2e
The Playwright config (../playwright.config.ts) builds the app (next build) and brings up Postgres before the specs run; setup/global-setup.ts seeds the auth + fixture state. The suite is not part of the fast local gate (typecheck / lint / test) — it surfaces at PR CI, so expect responsive/wizard/nav reworks to flag here first.
Layout
setup/—global-setup.ts(auth + DB seeding),test-helpers.ts(shared login + navigation helpers).utils/— fixtures such asmock-dashboard-snapshot.ts.*.spec.ts— one spec per flow: auth/login/redirect, dashboard, charts, the medication-wizard cadences (medications-wizard-*), insights generation + scroll restoration, doctor report, settings, mobile-viewport consistency, locale switch, accessibility (a11y.spec.ts), and thev1427-*regression set.
Convention
Assert against stable data-* attributes (data-slot, data-display-step, root display attrs), not viewport-dependent visible text. Responsive sm:hidden UI changes break getByText on desktop while the underlying element is still present — anchoring on data attributes keeps the specs stable across breakpoints. See ../CLAUDE.md.
