ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR introduces a large, cross-cutting find-in-thread capability spanning the web UI, timeline virtualization, history loading, shared Markdown parsing, server projection search, RPC contracts, and themes. It also changes default keyboard and server capability behavior, so the runtime and compatibility impact merits human review. Not approved because:

The find bar highlighted fence titles and language labels that the server never counted, and counted citation link text the chip never shows. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…drafts Each keystroke cleared the active result, which collapsed folded messages, details, and diagrams until the next response arrived. Drafts also took over browser find to show an update-server toast. Short viewports could scroll a match under the composer. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
… large messages Payload decoding ran inside the BEGIN IMMEDIATE snapshot, and messages over 32 KB were parsed again on every query. Decode after the snapshot, cache large parses separately, and bound the client-supplied skill labels. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Enter before results arrived replaced the viewport start with match 1, and closing find re-collapsed long user messages over the revealed match. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Opening find used to expand every disclosure, long message, and plan, and flip every Mermaid diagram to source, reflowing the whole timeline. Folded text now stays mounted but hidden: it still counts, and stepping to a match inside it dispatches beforematch so only that fold opens. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Imported V1 history has no run id, so its turns fold under a synthetic key. Find expanded the match's own run id, so every match inside a folded imported turn advanced the counter without revealing anything. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Base UI attaches its beforematch listener only while the panel is mounted, and a closed disclosure mounts its panel only once find starts, so the outer block of a nested match never opened. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
The find bar now floats inside the chat canvas at the card's 12px inset, and the card starts below it while find is open, so the two never overlap. It uses the card's glass surface with a quiet focus border, keeps its buttons inside the rounded ends, and closes the details popover in narrow windows where that popover would cover it.

The server counts find matches with the same remark/rehype pipeline the web renders with. Declaring those packages in two places with separate ranges could resolve two versions and make the counter disagree with the screen. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

- Plans render $skill tokens literally, so index them as written instead of by skill label (counts disagreed with the screen). - Build highlight ranges in one forward pass over text nodes instead of rescanning from the start for every match. - Ignore mutations outside searchable text, so per-second timers and status chrome no longer repaint highlights while find is open. - Normalize CRLF soft breaks the way the server does, and stop highlighting the image-unavailable fallback the server never counts. - Leave Mod+F to the browser on servers without thread search. - Look up timeline rows by id when reading the find start position. - Remove props and an import left over from the earlier implementation.

Long threads make earlier messages difficult to find, especially inside collapsed turns. Add find-in-thread to web and desktop with Mod+F, a command palette action, match navigation, and theme-aware highlights.
Search uses orchestration v2 contracts, services, and projected turn items. It scans the entire canonical conversation, including inherited fork history, and respects rollback visibility, cancelled queued messages, and answers folded into request cards. A bounded cache retains counts and item references for eight query snapshots. Thread revisions invalidate cached counts, including streamed updates and rollbacks. Cached navigation checks thread and fork-ancestor revisions without rebuilding the timeline index. The client reuses highlight ranges for unchanged rows and rebuilds them when text changes or a list row moves or is reused. Search responses contain counts and the selected match identity, without message bodies.
A new query starts at the first occurrence in or below the current viewport, including skipping occurrences above the viewport within a long message. If no later occurrence exists, it wraps to the first match. Next and previous navigate chronologically and wrap at both ends. Navigation is relative to the selected message and occurrence, so incoming matches before it do not shift the selection. Live thread updates refresh the count at most once per 300 ms, even during continuous streaming. Rapid clicks accumulate while the selected result is loading, and a live refresh preserves pending navigation.
Matches are revealed within the normal conversation. When the target is outside loaded history, the client fetches existing history pages until the message is available, then unfolds its turn and scrolls to the occurrence. There is no separate nearby-message search view. Visible occurrences retain their scroll position. Closing search keeps the reading position and opened turns. Pending navigation retains the selected result and counter; "Searching..." appears only while a new query has no result.
Switching environments discards the previous search, including when both environments contain the same thread ID. Search requires server support. On older servers, the palette action is hidden and the shortcut explains that the server needs updating. The renderer and search share Markdown transforms so matches follow displayed text. Search colours remain configurable in the theme editor and VS Code / Open VSX imports.
Rewritten around orchestration v2 and rebased onto the latest PR commits, preserving their folded-message, imported-conversation, and review fixes.
Validation
git diff --checkpassed.Earlier v2 checks included 355 focused search/projection/Markdown tests and 249 RPC/thread/theme/keybinding tests, plus type checks for shared code and the desktop build. Earlier browser assets below describe the archived v1 implementation.
Earlier v1 browser evidence, retained for reference
The recordings and screenshots below were captured before the v2 rewrite. They do not verify the current implementation. Commit references and verification claims in this section refer to that earlier version.
Updated default highlights —
fb72d5007Idle matches use
rgba(253, 184, 51, 0.3)in OKLCH; the active match uses warm amber (#eea52b) with dark text. Theme overrides remain unchanged. Light and dark screenshots below were captured from the rebased app, with client A searching client B. Remote navigation and returning to the conversation also passed.The earlier full verification set below was captured at
fbe5cb8eb(before the default-colour update), using isolated Chromium and native 1920×1080 capture. Videos are H.264 MP4; setup/idle pauses are trimmed where noted, without speeding up interactions. Uploaded withgh-image.Search and virtualization — default light/dark
A fixture with 1,000 turns / 3,000 messages contains four distant matches, including folded progress and code. All four highlights were visible after navigation; forward/reverse wraparound and closing/reopening find worked. The server-search pass mounted 20–22 timeline rows in total, including the retained conversation and search-result timelines.

Both captures use the latest commit; this compares UI states, not old/new source revisions.
Remote environment — two running T3 instances
Ran two independent T3 instances with separate state directories. From instance A (
localhost:8455), added instance B (localhost:8456) through Settings → Connections → Add environment → Remote link, using B's pairing code. The browser stayed on A throughout; search requests for B's thread went to B's WebSocket.Verified all four distant matches in B's 1,000-turn / 3,000-message thread, forward/reverse wraparound, light/dark highlights, closing find, and searching again after reload. Search responses carried only 4–6 nearby messages during distant-match navigation.
The same thread ID exists in both environments, but only B contains
formatneedle: B returned 2 matches; A returned 0; returning to B and reloading still returned 2. Captured WebSocket requests/responses confirm each query reached the selected instance. No browser page errors occurred.Two-instance verification — 22 seconds, native 1080p

Themes — VS Code JSON, Open VSX, and live editing
Imported explicit VS Code find-match colours in light/dark themes. In the theme editor, changing the current-match colour updates the highlight immediately; Cancel restores the imported colour. The recording shows both appearances.
