01 — 13:00 UTC Cycle Verification (PASS, 5 cycles)

4 min read Revision 1

01 — Post-Containment Cycle Verification (Track A)

Verdict: PASS_RECURSION_CONTAINED. The first post-fix 13:00 UTC executor cycle — and every executor cycle since — fired with zero recursion births.

How this was verified

Session opened at ≈12:00 UTC 2026-06-05, before the 13:00 cycle → classified PENDING_TIME with an exact watch. The watch was then executed against live data after the cycles fired (the run spanned the date rollover, so by capture time it was 2026-06-06 01:36 UTC and five post-fix cycles had completed — far stronger than a single-cycle check).

Pre-fix, every cycle = 4,043 entity_labels + 1,013 system_issues ≈ 5,056 births. Post-fix, every cycle = 0 entity_labels and a handful of system_issues. Total birth growth across ~13h and 5 cycles = +36 (1,210,742 → 1,210,778). An uncontained run would have added ~26,000.

Acceptance result (v_birth_fix_cycle_acceptance_result)

# criterion target actual state
1 H11a stays detect_only / auto_fix NULL 0 heal detect_only / auto_fix=NULL PASS
2 heal-driven entity_labels births 0 0 PASS
3 anti-loop heal_description_basic regen rows 0 0 PASS
4 exempt-collection births 0 0 PASS
5 legitimate detect-only findings bounded 14 INFO

heal_description_basic (the recursion source) has produced 0 rows since the fix; last-ever row at 2026-06-05 10:01 (the last pre-fix cycle). Idempotency confirmed working: repeating findings coalesce (H11b max occurrence_count=9, HC-SCHEMA=9, dot-dot-health=5) instead of re-birthing.

What the 14 system_issues at 13:00 actually were

Not the H11a recursion — they came from other health crons that ran near 13:00:

  • dot-context-pack-verify (7): H1 manifest age, H2 section file exists, H3 checksum, H5 size, H7 mermaid, H8 JSON schema — distinct real findings.
  • dot-dot-health (7): DOT-H4 phantom, DOT-H7 orphan, DOT-H10..H14 — distinct real findings.

Minor follow-up discovered (NOT the explosion)

A few checks (notably dot-context-pack-verify / check_manifest_age) embed a changing measured value in the issue title (age=789.50h, then 789.00h, …). Because fn_log_issue's coalesce_key includes the title, each run mints a new key → a new birth (~2/cycle) instead of coalescing. This is a bounded, non-recursive leak (~tens/day) in those specific check definitions — not fn_log_issue itself. Recommended fix: keep the title stable (e.g. "H1 Manifest LIVE age exceeds critical_hours") and move the measured age into description/evidence_snapshot. It also surfaces a genuine stale-manifest issue (≈789h ≈ 33 days).

Track A result: PASS. No unsafe action taken; live evidence (5 clean cycles) wins.
