Solomon round 5 audit (post ee38745, Cycle 6 launch)

[DrJops]

Summary

Round 5 external audit of the Cycle 6 specification package commit ee38745 "Launch Cycle 6 package for A01 real-pipeline validation".

Different nature from rounds 2-3-4: this is a preregistration audit, not a post-execution audit. Cycle 6 status is "specification package, execution not started". No seal compiled, no trajectory log, no theorem state changes possible.

All four round-4 §6 operational recommendations addressed in verifiable artifacts:

1. Real pipeline implementations — CYCLE_6_A01_REAL_PIPELINES_SPEC §2: P_cls and P_ord modular distinct, no shared scoring function, separate code paths and lock hashes.
2. Systemic auditor independence — CYCLE_6_EXTERNAL_AUDIT_PLAN §1: two-auditor rule introduced ("No theorem promotion without two external audit notes"). Significant policy advance. Secondary auditor still TBD.
3. Workflow firma auditor — EXTERNAL_AUDIT_PLAN §4 Decision authority split: designer prepares/executes/drafts, auditor signs entry/exit and confirms promotion admissibility.
4. Stress test 0/135 — explicitly cited in CYCLE_6_OVERVIEW §"Why Cycle 6 exists" as motivation for the cycle.

Round-2 §3.F closed substantively: BENCHMARK_INDEPENDENCE_PROTOCOL defines four independence conditions, zero-overlap acceptance threshold, canonicalized hashing.

Open points to resolve before gate-entry (all MEDIUM or LOW):

• §3.A eps_err_match=0.01 threshold inherited from stress test, likely too tight on real pipelines (raccomandazione: scan pre-registrato di soglie [0.01, 0.03, 0.05, 0.10])
• §3.B mean_Coh_trajectory formula on real trajectory not yet specified — must be in the formula_lock before gate-entry
• §3.C Benchmark TBD (public vs generated tradeoff explained)
• §3.D Secondary auditor TBD blocks promotion of principle
• §3.E Claim_lock Cycle 6 not created (must have cycle_sequence_index: 2 since A01 was at index 1 in Cycle 5)
• §3.F-G-H minor: check_gate_compliance.py extension to Cycle 6, "2/3 contexts" ambiguity in decision criteria, dispute resolution between primary and secondary auditors

Solomon confirms availability to sign gate_entry_signature for A01 Cycle 6 once §3.A through §3.E are resolved. §3.F-G-H are refinements, not blockers.

Compliance check: third consecutive round of reproduced compliant=true on Cycle 5. No state changes for Cycle 5 theorems.

Decisions invariate: A01/D02 revise_needed confirmed, D03 reject_candidate confirmed. Cycle 6 has not yet produced evidence to change any decision.

Test plan

• python3 OCT/validation/runtime/check_gate_compliance.py — compliant=true, 0 errors per theorem (Cycle 5 invariate)
• All four round-4 operational recommendations cross-mapped to specific Cycle 6 artifacts with file/section references
• Round-2 §3.F (cycle3_inputs benchmark) closure verified at protocol level
• Five MEDIUM open points identified with concrete operational suggestions
• Three LOW refinement points identified for the longer arc
