Summary

  • Investigated T4 ("0-chunk status bug + TUI i/d/f diagnostics"). TUI half: confirmed no code bug - real keybindings are i/d/n/r/l/q (footer hints match handler 1:1), the "f" in the title never corresponded to real code. Marked resolved as a stale-title/docs mismatch.
  • 0-chunk status half: traced index_status_impl, VectorStore::stats(), with_vector_store_read_for, and force_reindex_with_stores - no staleness/caching defect found via static tracing. Deliberately did NOT make a speculative code change; rewrote the AGENTS.md entry to be accurate and actionable, left open pending a live repro.

Test plan

  • Docs-only change, no source touched (verified via diff --stat)
  • Reviewed via reviewer agent - PASS

Investigated T4 ("0-chunk status bug + TUI i/d/f diagnostics"):

- TUI i/d/f: traced handle_key() + render_footer() in
  src/serve/tui_common.rs. Footer hints match the key handler exactly
  (i=info, d=doctor, n=reindex, r=remove, l=reload, q=quit). No `f`
  binding exists anywhere in the codebase - the "f" in the TODO title
  didn't correspond to real code. Marked resolved as a docs-only
  mismatch, not a bug.

- 0-chunk status bug: traced index_status_impl, VectorStore::stats(),
  with_vector_store_read_for, and force_reindex_with_stores. All read
  fresh state per call; force reindex mutates the existing store
  in-place rather than swapping the Arc, ruling out the stale-handle
  hypothesis. No concrete defect found via static tracing - left open
  with a note that it needs a live repro before any fix is attempted.
