ultraindex — the verified knowledge layer over codeindex

For engine evidence and coverage limits, read engine-evidence.

For a handoff that claims every answer claim was checked, use verify --complete --answer <file> --repo <dir>. Read and adjudicate the current batch files listed in VERIFY.md (default 40 pairs each; --batch-size changes that). Fold the comma-separated verdict paths with verify --apply, then gate with check --answer <file> --semantic --complete. Default verification is sampled; do not describe it as complete when pairs remain uncovered. Generation is only a worklist, and support still requires reading the excerpts.

The mechanical work is not ours. ultraindex vendors codeindex — a deterministic, zero-dependency, keyless engine — and it does the scanning, symbol extraction, import resolution and link-graph (node scripts/ultraindex.mjs <command> — no npm install, no API keys, run --help for the full surface).
