The docked panel was part of the page, below the top bar. It is now a column of the shell beside the content column, portalled through a new side-panel slot: it runs from the top of the window to the bottom, flush right, and the top bar ends at its left edge. Shut, the panel is gone entirely and the top bar runs to the window's edge. The panel's header row is the top bar's band, so the two bottom borders draw one line; the panel takes the sidebar surface and border, like the rail on the left. The top bar says where the reader is on desktop: "Coach", then the open conversation's title, truncated. The panel toggle is its last item, 12 px from its trailing edge, so it stands against the open panel and at the window's edge when the panel is shut; it carries a tooltip and is 28 px beside a fine pointer, 44 px with touch. New chat is a round 48 px primary button with a plus, 24 px in from the panel's corner (16 px in the phone sheet), with a tooltip. The top bar's action slot and the new context and side-panel slots share one portal helper.
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/—test.ts(the suite'stest+expectentry point),global-setup.ts(auth + DB seeding),test-helpers.ts(shared login + navigation helpers).utils/— fixtures such asmock-dashboard-snapshot.ts.fixtures/— synthetic payloads a journey uploads, built in code rather than committed as blobs so the content stays reviewable (apple-health-export.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.
Conventions
Import test and expect from ./setup/test, never from @playwright/test — types (Page, Route, …) still come from the package. The entry point extends Playwright's test with an automatic fixture that drops route handlers and page listeners after every test, so a handler left in flight cannot fail the test it belonged to once the context closes. src/__tests__/e2e-route-cleanup-guard.test.ts enforces the import boundary.
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.
