feat(web): find text throughout saved conversations

[maria-rcks]

ctrl+f could only search mounted browser text, so older messages in a virtualized conversation were missed. add conversation find over persisted message history, with occurrence counts, next/previous wrapping, exact text highlighting and automatic loading and expansion of the matching row. background-task notifications are excluded because the timeline renders them as work items.

verification:

• real stopped history: 71 "mermaid" occurrences, including the oldest initially unmounted message; next, previous, wrapping, multiple matches and no results passed.
• long user messages expand for a match, and "show less" remains actionable. escape clears the highlight and returns focus to the composer.
• command palette and customizable ctrl+f passed; terminal and browser URL-input focus retain their shortcut ownership. global sidebar search is unchanged.
• 1280px and 430px layouts checked in light and dark. 231 existing search/timeline tests, scoped lint/format checks and server/web typechecks passed on blacksmith for the final commit. earlier contract/client-runtime/shared checks also passed.

web client/server behavior was exercised using saved claude and codex history. native electron, macos shortcut behavior, hosted browser content find, remote/tunnel runtime and other provider sessions remain unverified. mobile has no find UI in this keyboard-focused change.

when saved Markdown or legacy context text has different occurrence counts from the formatted message, find shows a bounded excerpt with the exact saved match. reopening find from the palette refocuses its input.

find also follows visible fork ancestry and cutoff rules, omits rolled-back/cancelled local items and replies folded into answered question cards, and limits positioning retries to eight. wheel/touch/pointer/scroll-key input cancels pending positioning.

rechecked the real 28-match files history: next/previous reach the highlighted old message, a manual scroll moved 4368.5→4798.5 and held, and escape closed find at the same offset. original runless/fork/async-answer and pathological retry runtime cases remain unverified; existing focused tests cover projection visibility and runless expansion.

implemented and verified with gpt-6.1-sol in codex.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR introduces a cross-layer conversation-search feature with a new authenticated RPC, recursive history handling, and complex virtualized-timeline navigation. It also adds a default Cmd/Ctrl+F product binding and modifies an auth package, so the scope and impact warrant human review.

Note

Written by gpt-6.1-sol on behalf of Maria

browser verification and before/after evidence are in the PR body. two independent final source reviews approved d405593; the persisted-source mismatch and palette refocus findings are addressed. native and remote paths remain explicitly unverified.

📝 Walkthrough

Walkthrough

This change adds server-side search for text occurrences in persisted thread messages. The web interface opens conversation search from the command palette or shortcut, queries the new RPC, and navigates to matching messages in the timeline.

Changes

Conversation Find

Layer / File(s)	Summary
Search contract and server operation packages/contracts/src/threadSearch.ts, packages/contracts/src/orchestrationV2.ts, packages/contracts/src/rpc.ts, apps/server/src/orchestration-v2/ThreadSearch.ts, apps/server/src/ws.ts, apps/server/src/auth/RpcAuthorization.ts, apps/server/src/observability/RpcInstrumentation.ts, packages/client-runtime/src/state/orchestration.ts, apps/server/src/orchestration-v2/ThreadSearch.test.ts	The findThread RPC accepts a thread ID, a trimmed query, and an optional occurrence index. The server counts case-insensitive occurrences in eligible messages and returns the indexed match. Tests cover literal matching, message filtering, and fork-history visibility.
Search controls and entry points apps/web/src/components/chat/ThreadFind.tsx, apps/web/src/components/ChatView.tsx, apps/web/src/components/CommandPalette.tsx, apps/web/src/commandPaletteBus.ts, packages/contracts/src/keybindings.ts, packages/shared/src/keybindings.ts, apps/web/src/components/settings/KeybindingsSettings.logic.ts, apps/web/src/keybindings.test.ts, apps/web/src/index.css, docs/user/thread-sidebar.md	The search control debounces queries, reports errors, and wraps previous and next navigation across matches. The command palette and mod+f open search for the active server thread. The documentation describes the controls and keyboard actions.
Timeline match navigation apps/web/src/components/chat/useThreadFindTarget.ts, apps/web/src/components/chat/MessagesTimeline.tsx, apps/web/src/components/chat/MessagesTimeline.logic.ts, apps/web/src/components/chat/MessagesTimeline.test.tsx	The timeline loads earlier history when needed, expands the matching turn or attempt, and positions the selected occurrence. It displays source-text context when applicable and highlights rendered matches when supported.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 7d0b9

Existing authentication and read permissions are retained. However, each search and match-navigation request recomputes occurrences across the conversation’s saved history, including fork ancestors, on a shared synchronous database connection. Repeated requests could delay other operations in the same environment. Worst-case history sizes and execution times remain unverified.

Retained concerns

• Medium · security · inferred: An authenticated reader can repeatedly invoke exhaustive occurrence counting across local and inherited history, including archived threads, on the environment’s shared synchronous database connection. Returning one match bounds response size, not execution work. This adds an availability-sensitive workload that can interfere with other operations in the same server process; its worst-case impact is not measured.

Security review details

Security Blast Radius

• inferred — The availability concern requires an authenticated connection with orchestration read permission and affects the selected environment server’s shared execution and database resources. The inspected path does not grant access to a different environment or introduce infrastructure, secret, or tool authority.

Security Findings and Attack Paths

• inferred — A read-authorized caller can bypass the UI debounce and repeatedly submit valid queries or different match indices for large histories. Each request recounts and orders all eligible occurrences before returning one target. Synchronous execution can delay unrelated work in the same process. This is an inferred availability concern, not a demonstrated outage; broad global-search scanning already existed at the base revision.

Trust Boundaries and Controls

• observed — WebSocket authentication supplies session scopes, and the RPC middleware checks orchestration read permission before execution. Search values are bound through the SQL template rather than interpolated as SQL syntax. The new handler follows the existing thread-read scope and identifier pattern; no PR-introduced per-thread authorization bypass was established.

Resilience and Maintainability Implications

• observed — The query detects ancestry cycles, the UI rejects stale search completions, and positioning attempts are capped at eight. These controls constrain ancestry loops and local navigation recovery, but they do not impose a database-work budget on the occurrence-counting request.

Hardening Proposals

• proposed — Evaluate large and deeply forked histories, including archived threads, and establish a server-enforced execution or admission budget. Consider reusable match results keyed to history revision or execution isolation that can actually interrupt synchronous SQLite work; a response limit or UI debounce alone does not provide that containment.

Thank you for hearing us, implementation backend is respectable, downvoting the UI 👎 move search menu to the right and have it float like a modal like chrome does

Note

Grok responding on behalf of Julius.

Closing as superseded. #10439 (find messages and plans in the current thread) just merged into main. It ships Cmd/Ctrl+F find-in-thread on web and desktop, backed by the server, and it covers unloaded history and folded turns, which is the same feature as this PR. Thanks for the work here! If something in this approach is still missing from main, please open a smaller follow-up against main.
