1) Objective and Protocol
- Objective: execute a strict 7-wave pure realtime full chain in the exact order S1 -> S2 -> T1 -> T2 -> realtime T3 -> realtime T4 -> T5.
- Execution directories:
- run: 03_execution/runs/WP0_B2A_RIGID_BRIDGE_20260513_R3_C0_EN7_PURECHAIN_RT_STRICT3_20260516T1747
- reports: 04_reports/C0_EN7_PURECHAIN_RT_STRICT3_20260516T1747_EN
- This report uses only machine-readable artifacts inside the STRICT3 directory and does not mix STRICT2 outputs.
2) Core Evidence Files
- Main ledger:
- EN7_C0_CANDIDATE_LEDGER.json
- EN7_C0_CANDIDATE_LEDGER.md
- Per-wave audits:
- EN7_W*_T1_CHANNEL_SEPARATION.json
- EN7_W*_T2_THREE_LAYER_CONSISTENCY.json
- EN7_W*_T3_REALTIME_AUDIT.json
- EN7_W*_T4_REALTIME_AUDIT.json
- EN7_W*_T5_STOPLOSS_DECISION.json

- Same-window linkage is valid across all 7 waves: T2 pair_count=1, T2 overall_pass=1, T3/T4=true, T5=conditional_continue.
- S2 layered pass is present in all 7 waves (W04 is 1; all others are higher).
- point4_independent_repro_check is True from W02 to W07 and False at W01.
4) T1 Judgement Basis and Integrity Boundary
Based on EN7_W*_T1_CHANNEL_SEPARATION.json:
- All 7 waves have target_pass=true under target_pass_definition = c0_academic_t1.
- legacy_target_pass_0_6 and legacy_robust_pass are retained as traceability fields and are not used as the C0 main field.
- Example (W01): target_pass=true while legacy_target_pass_0_6=false and legacy_robust_pass=false, consistent with the frozen C0 judgement mapping.
Boundary statement:
- This report states C0 closure only under the frozen C0 academic protocol.
- Legacy fields are preserved for traceability and do not override the C0 main judgement.
- No C1/C2 or theorem-level closure claim is made in this report.
5) Itemized Assessment Against C0 Five Conditions (STRICT3)
- S1 (continuous GO_T1): satisfied (target_pass=true for all 7 waves).
- S2 (layered stability): satisfied (layered pass exists in all 7 waves; most waves are >=3).
- Same-window linkage (T2/T3/T4/T5): satisfied (all 7 waves satisfy the linkage package).
- Independent replication (in-chain proxy): satisfied in-chain (point4=true for W02~W07).
- Governance and traceability: satisfied (full ledger + per-wave JSON lineage is present).
6) Conclusion
- The STRICT3 evidence package shows that C0 full-chain linkage is achieved across the 7-wave window under the frozen C0 academic protocol.
- The conclusion level is C0 (academic-standard closure), with no theorem-level upgrade.
