Ratify pipeline-fidelity gate new-data basis, fire sequence, #340 footprint sizing

[WilfordGrimley]

Summary

• Records owner-ratified rulings from 2026-07-23: the legacy-pilot comparison (Artifact 1) is closed history; the upcoming full-pool Stage D dry-run becomes the pilot/measurement of record going forward. No vote retraction — legacy/deduction votes stay in the DB and in consensus.
• Adds the full gated fire sequence to docs/pipeline-fidelity-gate.md (§9): deploy master → scoped re-extraction (Bug-B whole-DB reparse + Bug-A sample) → full-pool Stage D dry-run (the pilot) + owner sample audit + write → consensus_recompute --apply.
• Adds the Fix OCR short-circuit over-skip and glued language-marker set code #340 root-cause catalog-wide footprint sizing (§10, measured 2026-07-23T00:16–00:24Z, live read-only): Bug A 17,531 cards (91% eligible, ~0.2% expected conversion), Bug B 284 rows (212 eligible, 33 staged-run votes all conservative no-match).
• Adds the Stage C run-identity note (§11): Stage C runs aren't tracked in PilotRunLedger; evidence rows are fully persisted regardless; a ledger fix is a separate in-flight PR.
• docs/theory.md §7c: one in-register paragraph on the new measurement basis, provenance log line bumped per the file's own convention.
• docs/troubleshooting.md: two new symptom-first entries — docker exec ... ps has no ps binary (use docker compose top instead), and admin/moderation session drops after a backend deploy (mechanism unconfirmed, marked as such rather than asserted).
• Refreshed now-stale one-liners in CLAUDE.md/docs/README.md/docs/MANIFEST.md describing the gate page: the "still-open owner decision on two of three constants" language was inaccurate — that fix already merged as PR Stage D: apply the two must-fix resolution-floor / resolved-tag constants #343 (visible at current master HEAD) and is only awaiting deploy.

Test plan

• python3 .github/scripts/docs_lint.py — clean (link/path lint)
• python3 .github/scripts/tests/test_publish_wiki_link_rewrite.py — 4/4 pass (link-rewrite parity)
• python3 .github/scripts/publish_readme.py . regenerated readme.md and diffed clean against the committed file (no README-REGION markers touched by this change)
• Pre-commit prettier hook ran clean on the final commit
