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.

When "read documents automatically with AI" is on, the detail sheet no longer
shows the manual per-document action row (Read / Suggest / Summarise) — reading
already happens on upload, so the buttons only nagged. The section header and
the searchable status pill stay, and content search keeps working. With the
setting off the manual controls render exactly as before.
Drop the "review before saving" heading and its grey sub-caption from the
suggestion panel; the reviewable fields and the apply / dismiss controls stay.
Remove the now-unused documents.assist.reviewTitle / reviewHint keys from every
locale.
Add an e2e suite mocking the capability probe, the chat history GET, and the
streaming chat POST so the panel renders (v1.27.31 lesson): the entry opens an
empty safety-noted surface, a turn streams a reply that settles to one assistant
bubble, a non-indexed document shows the calm hint, and no provider leaves no
chat surface. Clear the streamed tail + optimistic bubble once the persisted
twin lands so the reply never double-renders.
