## Why `codex resume` regressed after [#18502](https://github.com/openai/codex/pull/18502) changed the default `thread/list` scan-and-repair path for metadata-filtered listings. The TUI resume picker uses `thread/list` with source/provider/cwd filters and `useStateDbOnly: false`, which is the intended correctness-preserving mode: it should still consult the filesystem so healthy, missing, or stale SQLite state can be repaired. The regression was that #18502 made that filtered, filesystem-backed path call `reconcile_rollout` for every filesystem hit, and then call it again for each SQLite hit. When `reconcile_rollout` does not already have extracted rollout items, it falls back to loading the full JSONL rollout. That changed the resume picker’s first page from a cheap rollout-head scan plus SQLite read-repair into full-file reads for large sessions, so a few long threads could dominate TUI startup/resume latency. This change addresses the regression by keeping `useStateDbOnly: false` on the correctness-preserving path while avoiding unnecessary full JSONL reads for rows the filesystem scan has already validated. Source/provider/cwd filters can be decided from rollout-head metadata, so non-search resume listings only need the lightweight read-repair path for filesystem hits. Full reconciliation is still used for DB-only filtered rows because those can be stale false positives, and for search listings because search can depend on title metadata that may require scanning the full rollout. This fixes #19483. ## What changed - For non-search filtered listings, repair filesystem hits with the lightweight `read_repair_rollout_path` path instead of full `reconcile_rollout`. - Track thread IDs proven by the filesystem scan and only fully reconcile SQLite-filtered hits that the filesystem scan did not return, preserving stale-DB false-positive cleanup without full-reading every healthy rollout. - Leave search listings on full reconciliation, since search depends on full title metadata rather than only source/provider/cwd metadata from the rollout head. ## Verification - `cargo test -p codex-rollout list_threads` - `cargo test -p codex-app-server thread_list`
