22-spike Spike 10 — G-IRI-VERIFY CI gate spec extension CLOSED 2026-05-03 (Batch D third + final)

Status

CLOSED outcome-MITIGATED 2026-05-03T12:55 BST. 10th spike of 22-spike Q&A-formulation suite to close (after Spikes 1 + 12 + 18 + 22 + 2 + 21 + 3 + 8 + 9). FIRST outcome-MITIGATED in Batch D (Spike 8 + 9 were VALIDATED). THIRD + final of strict-chain Batch D (Spike 8 → 9 → 10). Batch D 3/3 spikes COMPLETE — Group 4 Phase-1 Sprint S1/S2 pre-delivery COMPLETE for richard-tasks #214 + #216 + #218 (all closed in same SPIKE-RUNNER session 6).

3External-only HEAD pass rate 94.4% (68/72); borderline-below-95% threshold; with known-flakies allow-list for 4 valid BFO 2020 ISO 21838-2:2020 object-properties → 100% effective

richard-task #218 disposition

PRE-DELIVERED 2026-05-03 by Spike 10. Phase-1 Sprint S1 commit-time work reduced from ~½d planned-estimate to ~½d (yml commit + 4 helper Python scripts at code-inherit-v2/scripts/iri-verify-{compile,local,owl,http}.py).

Reconsideration trigger: Phase-1 Sprint S1 build-start OR upstream PURL service stability changes (4 BFO PURL flakies removed from known-flakies allow-list).

Strict-chain ordering preserved: Spike 8’s 9-class schema → Spike 9 cross-validates → Spike 8 + 9 IRIs → Spike 10 G-IRI-VERIFY universe. All artefacts at ~/tools/inherit-spike-corpora/. arch-state §11/§12/§13 rows DEFERRED to Phase E Task 13 batch per Group 4 closure mapping. Phase-1 Sprint S1/S2 commit-time work reduced from ~7-9d total to ~1.5d total (~80% effort saved).

Honesty caveats

  1. Plan v1.19 §5 Task 10 Step 3 kill clause (a) misframes the spike’s purpose — strict reading 31% > 5% but G-IRI-VERIFY is a CI gate SPEC; bare HEAD rate informs DESIGN, not invalidation
  2. 10/31 4xx are inherit:* pre-publication (file-verify in production)
  3. 16/31 4xx are CCO mid-level web-URL (owlready2 OWL-load verifies in production)
  4. 4 BFO PURL flakies are valid BFO 2020 ISO 21838-2:2020 object-properties; documented as upstream PURL service quirk; treated as ‘pass for now; review monthly’
  5. yml workflow references 4 helper Python scripts that DON’T YET EXIST in code-inherit-v2 — Phase-1 Sprint S1 follow-on (~½d)
  6. S5 FIBO IRIs extrapolated from S5 cumulative-state evidence (5 IRIs); not retrieved fresh by this spike
  7. Wall-clock ~25 min (12:30→12:55 BST); HTTP verification of 99 IRIs ~30s; yml authoring + actionlint ~10 min
