⌘F opens a find field in the chat's top-right corner. Matches are highlighted in both your messages and the agent's, and ↑/↓ or Enter steps through every occurrence. The ⌘K palette gets a Messages tab (⌘3) that searches the text of every chat. Opening a result opens that chat with the same words already in its find field.

How

• Engine (crates/engine/src/transcript_search.rs): a new SearchTranscripts RPC backed by a SQLite FTS5 index beside the profile store, with one row per user or assistant message. Reasoning and tool output aren't indexed. Each search first refreshes chats whose snapshot changed, within a 1s budget, and drops deleted chats. Every query word must match as a literal prefix, so FTS operators in user text stay inert. Hits carry the chat id, a snippet and from_user.
• Sync (crates/sync/src/store.rs): snapshot saved_at lookups for the refresh, kept outside the numbered migrations.
• Find in thread (crates/ui/src/find.rs, transcript.rs):
  • Matches are counted per rendered row (user text, or the row's markdown block) and stepped per occurrence.
  • The painters highlight matches under the text in markdown paragraphs, lists, tables and code lines, and in user bubbles. The current match is stronger.
  • The field takes the session cards' slot (same width and card styling), and the cards stack below it while it's open.
  • The shortcut is rebindable (find_in_thread, default mod-f). It only fires on a chat, so it doesn't clash with ⌘F in settings search (Settings search: find any setting from the sidebar, with ⌘F #1018).
• Palette (crates/ui/src/shell/command_palette.rs):
  • Messages sits third, after Threads. All shows a short "In messages" section after Threads.
  • Rows show the title, project · device, time, You:/Agent: and the snippet with the matched words bold.
  • Threads matches titles only.

Tests

• cargo test -p zeron-engine --test transcript_search passes. The new test covers user and assistant text being found, reasoning staying out, every word having to match, hostile FTS input, delete, restart, and rebuilding after the index file is removed.
• cargo check -p zeron-ui passes.
• Tried by hand in a Linux release build: find highlights both kinds of message, the counter steps per occurrence, and palette results open the chat with the find field filled.

Not verified

• macOS, Windows, mobile.
• Opening a palette result jumps to the chat's first match, not necessarily the message that was clicked. Restoring a saved scroll position might also override the jump.
• Paragraphs whose links get shortened on screen can mark the wrong match as current.
• The index rebuilds from scratch on the first search after upgrading (schema v2).
