* fix(ui): make indexed access explicit across the Control UI
Burns down all 322 ui-lane noUncheckedIndexedAccess errors: untrusted
markdown/diff/patch parsing gets miss-tolerant guards (renderer rules
degrade to empty output instead of throwing mid-render), accumulators
use canonical sparse initialization, DOM lookups stay null-guarded, and
length-checked constructions carry named invariants.
* feat(tooling): enforce noUncheckedIndexedAccess in the core and ui lanes
Flips the flag on for tsconfig.core.json and tsconfig.ui.json (covering
src, all packages including the two deferred ones, and ui) and retires
the strict-ratchet lane wholesale: config, script, projects reference,
check/CI wiring, changed-lane routing, and sync test. The assertion-ban
oxlint override stays as an independent surface.

Adds a git-backed session diff panel to the Control UI, complementing the existing PR status chips.
New sessions.diff gateway method (operator.read): resolves the session checkout and returns structured per-file diffs (status, renames, +/- counts, capped unified patch) of branch + uncommitted + untracked work against the default-branch merge base. Hardened against git textconv execution and hardlinked out-of-tree content leaks; handles repos before their first commit via the empty-tree base.
Control UI renders a "Changes" panel in the chat detail sidebar with collapsible per-file diffs, hunk-gap markers, stat chips, and untracked/binary badges, gated on gateway method advertisement. Schemas additive (Swift models regenerated), 20 locales translated.
Closes#104182
* feat(webui): reintroduce opt-in AI purpose titles for tool calls
Restores the chat.toolTitles path removed in #103821, gated behind the new
gateway.controlUi.toolTitles opt-in (default false) so tool rendering stays
fully deterministic with no background model calls unless an operator enables
it. Disabled gateways answer { titles: {}, disabled: true } without loading
the completion runtime, and clients stop asking for the session.
When enabled, titles use canonical utility-model routing: an explicit
utilityModel (operator-chosen provider, like every utility task), else the
session provider's declared small-model default, honoring per-session model
overrides and auth profiles; utilityModel "" disables titles and malformed
refs fail closed — never the primary model. Tool inputs are redacted with the
tools-mode redactor before cache keys or prompts, caller ids are bounded and
never reach the model, and results cache in the per-agent SQLite
cache_entries so repeat views never re-bill.
Also completes two crestodian model-input mock factories that leaked into
sibling tests under shared-registry CI shards.
Fixes#103987
* fix(webui): redact tool-title inputs before truncation
Kind-aware tool rows (terminal-style commands with wrapper stripping and
display highlighting, file edits with inline numbered diffs and diffstat,
write previews, key-value args), aggregate group summaries with live run
status, and a new batched chat.toolTitles gateway RPC that titles complex
calls via the configured utilityModel or the OpenAI Luna default (gated to
OpenAI-primary agents, cached in the per-agent SQLite cache_entries).
Also fixes two transcript pairing bugs: result blocks now inherit call
id/name/details at merge time, and results pair with any open call in the
current tool run so parallel calls render as single rows.
Fixes#103554
Adds client-capability-gated tool availability: gateway clients declare
capabilities at connect (new inline-widgets cap), chat.send stamps them into
the run context, and every tool assembly path (embedded runner, queued
followups, Codex app-server harness, plugin-only construction plans) drops
tools whose requiredClientCaps the originating client did not declare. The
Canvas plugin ships the first such tool, show_widget: agents pass SVG or an
HTML fragment plus a title; the plugin hosts it as a bounded, retention-scoped
Canvas document and returns the existing canvas preview handle, which web chat
renders as a sandboxed iframe fitted to the widget's reported content height.
Widget frames never get allow-same-origin (per-preview sandbox ceiling,
including the sidebar path) and the Canvas host serves widget documents with a
CSP sandbox header so direct navigation runs in an opaque origin. Verified
live end-to-end on a Testbox with gpt-5.5 (screenshots on the PR). CLI-backed
model backends do not carry client caps yet and stay fail-closed (#102577).
Closes#101790
Tool calls in Control UI chat rendered as triple-nested cards: activity
group card + tool-shell bubble chrome + gradient summary pill with a
0 8px 22px drop shadow. Collapsed rows now render as flat single-line
rows with ellipsis, the activity group uses a flat header plus a left
rule, and expanded detail keeps soft tinted blocks without card chrome.
Also deletes the dead legacy .chat-tool-card__details/__output CSS and
the unused renderToolCardSidebar path with its never-taken
renderToolDataBlock branches.
Closes#99760
Refactor the Control UI around route-owned page lifecycle and state while preserving existing behavior and design.
