`SessionSearchEngine.search()` over the PR 2 store: route ladder (phrase, AND, typo repair, OR), BM25 weights per corpus, one hit per session, fork folding, and a page. - `scope` picks the corpus and the engine never second-guesses it. `conversation` is user and assistant turns; `all` adds tool output and the identifier shadow column. Switching corpus while typing is PR 7's policy; an engine that widened on a miss would make a result impossible to reproduce from its own request. - Pagination is an offset into one ranked list, fenced by the index generation and by a hash of everything that changes the ranking. A cursor from another generation or another query is refused with a typed error rather than silently re-run. Ranking breaks every tie by session id, because a cursor indexes into that order and retrieval does not promise one. - Snippets and source presence are paid for by the page, not the list. A snippet past the per-hit ceiling is cut on a code point, never between `[[` and its `]]`, and flagged on the hit. - Source presence is read from the `files` table. No stat on the query path, and no `missing`: only a proven deletion may claim one, and this read cannot prove it. - `SESSION_SEARCH_CANDIDATE_LIMIT_DEFAULT` is an option, not a constant, and the result says when the limit was what cut the answer. - The engine is the only caller of `store.warm()`, on first search. Library only: no IPC, no settings, no Electron, nothing constructs it in production.
