Two hardenings on the chain outlet branch:
A throwing chain selector runs before its entry's SlotErrorBoundary
exists, so uncontained it blacked out the whole owner region and skipped
the remaining chain. It now degrades to a decline: reported via
console.error with the registrant identity, later entries still tried,
all-null/all-throw passes land on the owner fallback.
The elected entry's boundary is now keyed by entry identity: an unkeyed
boundary that failed on entry A survived a re-election and kept a
healthy entry B blacked out until the outlet unmounted. The key remounts
the boundary fresh whenever the election changes.
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.
- Add 'edit' to ToolRowVariant type and TOOL_VARIANTS mapping
- Add 'edit' title and summary key preference (path/file_path)
- Add IconEditOutline16 as the leading icon for edit variant
Two polish defects from the headless verification pass:
- .newSessionLabel/.footLabel declared their own transition shorthand,
which replaced .wide's opacity fade entirely (shorthands do not merge) —
the labels vanished instantly while everything else faded. The fade is
restated alongside max-width.
- The rail icons drifted off a common vertical axis: the 56px track holds
a 55px content box (1px column border), and the capsule rows kept their
1px border-width in the collapsed state, shaving their content to 23px
and pushing the search icon 2px right. Collapsed capsules now zero the
border-width (transitioning border, not border-color), the root gives
back the border pixel via asymmetric padding, and every surviving row
centers its icon — five glyphs on the track's 28px center.
The collapse read as a hard cut: only the track width animated while the
panel content swapped instantly and the rail icons bore no relation to the
expanded layout. Now the four control rows persist across the transition —
collapse toggle, new session, new workspace, search, the same top-down
order as their expanded rows — and morph their geometry (row heights,
paddings, margins, capsule borders) on the deepsuite curve, so each rail
icon is its expanded control converging onto the 56px axis. Wide-only
content (brand, labels, input, session tree) cross-fades over 200ms, stays
mounted while the collapse animates, and unmounts at the 300ms settle,
still dropping the sessions subscription. The search query moves up to the
root and survives the round trip; rail search focuses the surviving input
after expand instead of remount-autofocus.
