P3-S22.1 VERIFICATION DEBT-CLOSURE — DISPOSABLE / VERIFICATION-ONLY

Status: disposable research/audit namespace. NOT production, NOT ML training, NOT contract changes.

Scope

Closes the four P3-S22 verification-debt items:

Debt item	Script	Output
1. F2 numeric zone-boundary parity	s2211_s1_f2_boundary.py	output/s2211_s1_f2_boundary.json
2. Historical M30/H4 boundary-timestamp parity	s2211_s2_mtf_boundary.py	output/s2211_s2_mtf_boundary.json
3. Population-level terminal replay	s2211_s3_population_feasibility.py	output/s2211_s3_population_feasibility.json
4. P3-S21.1 coefficient-level re-audit	s2211_s4_coef_reaudit.py	output/s2211_s4_reaudit.json, s2211_s4_coefficients.csv, s2211_s4_repro.json

Governing documents

• docs/CODE_VERIFICATION_AND_SILENT_BUG_POLICY_v1.md (authoritative).
• docs/P3_S22_TERMINAL_INDICATOR_VERIFICATION.md (debt list §X).
• docs/P3_S12_ZONE_CONTRACT_REPAIR.md, docs/SMC_FVG_SPEC_v1.md, docs/SMC_ORDER_BLOCK_SPEC_v1.md (F2 contract).
• docs/SNIPERGOLD_CANONICAL_SETUP_CONTRACT_v1.md (§L MTF as-of; §C/§N gates).

Reproducibility

Every script is deterministic; expect byte-identical outputs on repeat runs except the generated_utc metadata field. Run twice and compare:

python s2211_s1_f2_boundary.py
python s2211_s2_mtf_boundary.py
python s2211_s3_population_feasibility.py
python s2211_s4_coef_reaudit.py

Findings recorded (see the debt-closure report)

• DISCREPANCY-ADJ-1 (Subphase 1): MQL5 production AF_FVGZoneState / AF_OBZoneState never assign mit_state = AF_ZONE_PARTIALLY_FILLED; a partially-filled zone is labeled UNMITIGATED(0) + partial_filled flag, while the frozen F2 contract and the committed research/reference chain encode it as PARTIALLY_FILLED(1). Consumer availability is identical (IsActive). Severity LOW; no consumer-visible or historical-result impact found. NOT repaired in this phase.
• DISCREPANCY-ADJ-2 (Subphase 2): the committed M30 gate is constant only within index-pair M15 segments (research resample construction), not within fixed-UTC 30-min buckets; it drifts across session gaps. H4 is constant within the frozen as-of grid (0 violations) except 9 US-market-holiday artifacts. Severity LOW-MODERATE; no setup-level impact demonstrated.
• Subphase 3: population replay classified UNVERIFIED - ENVIRONMENT/DATA REPRODUCTION LIMITATION (proven, not PASS).

Rules

• No production MQL5 file, no F1-F4 contract, no FEATURE_CONTRACT, no label contract, no dataset, no model is modified by anything in this folder.
• All mutation testing is performed on disposable in-memory copies only.
• This folder is committed only as audit evidence; it is not a runtime component.
