Summary

Ctrl+R searches earlier prompts and puts a selection into the draft without sending it. The picker starts in the current project, Ctrl+S searches every project, and Esc or Ctrl+C preserves the complete editor state.

• History: query retained ordinary user text in the existing session store, including archived sessions and rows retained by rewind or compaction. Fork and import copies appear once per message ID, while separate submissions of identical text remain separate entries. Filtering matches literal substrings without case sensitivity across the full prompt.
• Picker: show ages, first lines, project labels and a scrollable escaped multiline preview. Session and prompt pickers share typed page workers. Searches examine bounded batches and keep one worker in flight while query and scope changes retain only the latest requested search.
• Editing: Enter recalls full text through the input's existing replacement behavior, with slash completions refreshed. Alt+R redoes edits in the input and modal fields. A nonempty draft replacement takes two native Ctrl+Z steps to undo.
• Storage: revision 2 adds a partial index for original message-time pagination, preserving the content format and compatibility with older readers. Initial and continuation query plans use the index without a temporary sort.

Closes #421

Test plan

• Store regressions cover exact ordinary text, generated origins and tool results, retained and deleted rows, supported formats, scope, original-time ordering, logical deduplication, literal Unicode filtering and empty nonfinal pages. A real revision-1 database migrates without losing its row.

• Picker and app regressions cover stale results, rapid query and scope changes, empty-page continuation, draft selection, yank and undo preservation during a running turn, native redo, slash completions, modified Enter, short layouts and preview lines beyond 65,535. Nine snapshots cover the visible states. Explicit loading, completion and failure states preserve failed queries and partial results without claiming exhaustion.

• Focused mutations confirm the origin filter, scope, deduplication predicate, schema index, request identity and render boundaries are guarded.

• Isolated keyboard smoke at the final review-fix head covered Ctrl+R, scope and filtering, preview scrolling, Enter without submission, Esc, native undo, Alt+R and normal exit. Confirmed zero local mock requests and only the two invented fixture messages remaining stored. A synthetic page-load error preserved the query, suppressed false completion notes and recovered through a scope change.

• Final review-fix head verification: formatting, build, both Clippy commands, rustdoc, coverage, unreferenced snapshot rejection and the three pnpm checks. All 3,511 tests passed, with five paid live tests ignored. Changed executable line coverage is 99.65% (1,131 / 1,135).

• All nine CI checks passed on the final head, including Linux / macOS Nix, Linux / macOS / Windows Rust, lint, MSRV, the aggregate result and Codecov patch. Independent code and usability reviews have no remaining findings.

Manual Windows and real-model behavior were not tested.
