CI qualification on exact HEAD 6f97f3b51895e724c9102822babc2e4ea7d821a5 (2026-10-08): 9/9 triggered workflows SUCCESS.

• Merge Execution Guard: 1,367 passed / 0 failed / 0 skipped.
• Native Windows build/test/smoke/package: SUCCESS; portable single EXE artifact.
• Field-capture build: SUCCESS; field-capture artifact.
• The P7.6A dependency/docs HEAD previously passed 11/11; only 9 workflows triggered on this narrow P7.6B PR. Do not represent untriggered workflows as executed on this HEAD.
• PhysicalVerified = NO. MergeReady = NO. Merged = NO. Released = NO.

Scope (stacked draft on P7.6A #480)

• Base: fix/446-p7-6a-scl-ap-bound-endpoint-provenance, exact base SHA 0a5226b7f3bdc63653c823745fc3c242d14745ab.
• Preserve pinned ARIEC61850 P6.2 engine 352c81e6a798635c6addcee0683235ca87ad416d; no changes to engine or MMS, RCB activation, polling, GUI, or controls.
• Guard false semantic parity MATCH when the evidence is ambiguous/incomplete: source model IED identity doesn't match selected IED, multiple normalized DataSet definitions, duplicate/negative member indices, empty member reference/FC, selected reference/FC missing, static-family contradiction, or plan coverage counters inconsistent with runtime selections.
• These conditions produce existing INCOMPLETE EVIDENCE / InsufficientEvidence verdict, not a fabricated mismatch or synthetic value.
• New synthetic regression tests cover negative cases and legitimate indexed-RCB-slot variability.

Stage and safety

CodeCommitted and CIPassed, physical testing pending. This is P7.6B evidence-integrity stage only; semantic/traffic equivalence of both real ingress paths, physical AP F switching, report integrity and lifecycle stress all remain PhysicalPending. Existing Open SCL 33/33 domains, 620/620 reads, 13/13 visible, 2/2 RCB ingress are not a dual-ingress proof.

• Do not merge/release automatically; remain draft.
• No private SCD, live field IP, or customer diagnostic content committed.
• CI regression gates + artifact inspection required on exact head.
• Parent #446; dependency #480, engine #153.

D16 checked historical PR #481 against protected RC 817c3910e8223fa2ac531a4426ada5d2d4bbbe50:

1. Historical HEAD 6f97f3b51895e724c9102822babc2e4ea7d821a5 is ancestor of the RC (GitHub compare: behind=0); its two changed paths are present in RC. This is ancestry integration, not a fresh merge into main.
2. Original regression tests/ARSAS.Tests/StaticAcquisitionParityIntegrityP76BTests.cs is byte-for-byte identical at historical HEAD and RC (Git blob SHA comparison); both positive and adverse-path assertions remain intact.
3. Evolved implementation Services/StaticAcquisitionParityTracker.cs is not byte-identical; checked that RC still implements the original invariant: IED identity mismatch, duplicate normalized DataSet rejection, invalid/duplicate FCDA ordinal, static BRCB/URCB family and requested-point coverage checks; source retains these exact fail-closed diagnostic evidence checks.
4. Exact RC-head Windows CI and R7 SCL CI completed SUCCESS. These do not claim physical-device acceptance.

Decision: close as integrated/superseded by RC #727/#729; no independent semantic/test delta requiring another merge. Do not cherry-pick this old stacked branch. Keep overall issue #446 and physical release gates independent; ARSAS main, stable v1.6.42, ARIEC engine pin and concurrent-owner branches remain unchanged.
