"""Pre-publish gate: mechanical checks before any public table ships.

Run against the result files you intend to publish:

  python3 scripts/publish_gate.py results/latest.jsonl results/latest.mount.jsonl ...

Checks (fail = exit 1; manual items print as MANUAL and never fail the gate):

1. calibration     docs/token-calibration-factors.md exists and is committed —

                   published token deltas must cite calibrated factors, not

                   raw char/4 (README warns char/4 is biased for VCS output).

2. tuned-git       core-lane results include git_untracked_cache AND

                   git_fsmonitor subject rows. Stock git alone overstates oak

                   wins on wide trees.

3. transports      no row set mixes remote transports under one operation

                   name (remote.net.* vs remote.*); rows touching a remote

                   carry remote_transport.

4. levels          agent rows carry instruction_level and the file holds only

                   one level (never aggregate across levels).

5. nulls           null means unmeasured: summaries must not render null as 0.

                   (Spot-checked by scanning for '| 0 |' columns whose JSONL

                   value is null — heuristic, reported as MANUAL.)

6. skips           every returncode-77 row carries skip_reason (work items,

                   never silent absence); count is printed for the summary.

7. tails           rows with tail percentiles carry their sample counts

                   (tail_latency_summary embeds n; absence is a failure).

8. provenance      published Oak subject rows carry clean Oak source

                   provenance (hash present, status clean).

9. samples         public core rows carry enough repetitions per

                   subject/scenario/operation group (n>=30).

10. randomization  public core rows state whether subject order was randomized;

                   randomized rows carry the per-run subject order.

11. failures       public rows do not hide failed operations behind successful

                   averages.

12. tracks         each result file holds one benchmark_track.

13. env-isolation  public core rows carry one env isolation version so rows

                   measured before/after harness environment policy changes

                   cannot be compared silently.

14. conformance    inputs holding Oak rows also hold diagnostic conformance rows

                   (scripts/vcs_conformance.py --output) for every published Oak

                   binary; the Oak rows pass the conformance gate against

                   config/conformance_expected_failures.json (no regression, no

                   missing behaviour, no FIXED-but-still-listed entry).
