Four rounds of structural rework on the conversation surface, converging
on one registration model for the whole client:
- Review fixes: open() leaves the inject factory (SessionsService owns
the semantic); ConversationService mounts via ctx.plugin(); the
bespoke view registry retires into the 'conversation.view' list slot.
- Ring alignment: createChatView factory retired (components get
everything through checkable shares at the register call site); the
hand-rolled t/i18n threading is deleted wholesale — a future
framework-level i18n will supply t as a standard prop keyed by slot
name, so no interim manual channel.
- Toolview dissolution: ToolViewRegistry / ToolViewResolver /
ToolViewOutlet / ctx.toolviews retire. Tool rows are entries of the
'conversation.chat.toolview' keyed slot (scope: session) declared by
the chat entry; ToolRowOwnerProps is the unified owner payload;
GenericToolCard becomes the call-site fallback; registrants are plain
plugins (inject ['slots','conversation'] as the load-order seam);
session-dimension dispatch moves into components (useSessions reads
parentId); trajectory/waterfall gain same-shape slots the day they
render tool rows (RendersCheck rejects empty declarations). Slot
names mirror the composition path (<domain>.<entry>.<hole>).
- Staging follows current: cell()/binding() are pure resolution
(render-safe); the constructor subscribes to the list store and
followCurrent opens the event window when the current session
changes — staging IS the open signal, business verbs are the timing,
React render/commit is decoupled from window lifecycle. A masked
current (projection gap) keeps the stage untouched so deferred
teardown semantics survive reconnects.
Agent Note: .agents/notes/implemented/architecture/
2026-07-23-toolview-dissolution.md (bilingual pair) records the
decision, the four rejected alternatives, and the accepted semantic
changes; the web client architecture note and packages/client/AGENTS.md
carry the current-state narrative.
Verified: typecheck 0, duplication 0 clones (478 files), full coverage
run 6190 passed with zero threshold errors, knip 0, doc-sync 24/24,
client aggregate tsc 0, render-count checks (one commit per chunk, zero
row re-renders under streaming) green.
