P9 exact-SHA Windows integration candidate (nonrelease)

Immutable provenance

• ARSAS source base: c7b7c68c6bf59a53082c09dd7584ea3d5312429e (consumer PR P8 field fix: SIEBCU first-connect retry, exact two-bit display and false no-report warning #766), which already passed canonical Windows CI and IO validation.
• Staged ARIEC engine: 58d22be43d93d1d439df04a99ba935a7ec45cd4c (P9 engine PR #200); engine CI #41980603839 1,292/1,292 PASS.
• Production engine pin remains: f75e323e9f8443aa20e0a3818a1d5d77255b2c0f.
• P8 PR P8 integrated reporting: stage ARIEC #198+#199 in exact-SHA Windows trial without changing FAT pin #763, ARSAS main, integrated RC and stable v1.6.42 untouched.

Scope

Use the existing label-gated, explicitly nonpromotable ci-p1-shadow reporting integration pipeline; update only the trial manifest and add backward-compatible P9-specific artifact filename. Fail closed if the manifest's engine SHA disagrees with exact checked-out engine; preserve legacy P8 naming for a P8 manifest. The test workflow includes Windows solution build, focused reporting regression, native bridge CTest, single EXE build, executable smoke, and exact SHA256 manifest.

No premature acceptance

CI success will prove build/smoke and synthetic correctness, not SG7 physical 77/77 or 4/4, first-click reliability on SIEBCU, or lossless SOE. Keep this PR Draft, test artifact nonrelease, and SG7 issue #707 Open. No hidden cyclic MMS polling, blanket RCB ownership mutation, or automatic control is authorized.

Please keep the separate P8 and P9 source branches intact to avoid cross-thread collisions.

P9 exact-SHA software milestone — CI verified, NOT physical acceptance (2026-11-05).

• Engine P9: 58d22be43d93d1d439df04a99ba935a7ec45cd4c, ARIEC #200, .NET CI #41980603839 1,292/1,292 PASS. Full four-RCB identity routing, no per-frame candidate arrays in exact RptID path, bounded delivery, close/reset admission barrier and association registry tests.
• ARSAS Windows consumer: 063cf6e26c401e0586dc440adb5e646d8e74b0cd, nonpromotion PR #767 stacked on already verified P8 consumer PR P8 field fix: SIEBCU first-connect retry, exact two-bit display and false no-report warning #766.
• P9 integrated Windows run #41981252170: SUCCESS; exact source/engine SHA gate PASS; 951/951 focused ARSAS reporting regression PASS; native ArdIrec bridge/CTest PASS; portable single-file EXE build PASS; portable EXE smoke PASS; artifact upload PASS.
• Download Windows x64 P9 trial: ARSAS-REPORTING-P9-TRIAL-58d22be4-win-x64.exe (artifact ID 13394580582; GitHub login/access may be needed).
• Exact EXE SHA-256: 23b5742166605b16c1e015d0f584e1eaf936dbb2a5dac62d2d988b22c4ea2f76.
• Baseline engine pin preserved: f75e323e9f8443aa20e0a3818a1d5d77255b2c0f. Main/RC/stable release, P8 PR P8 integrated reporting: stage ARIEC #198+#199 in exact-SHA Windows trial without changing FAT pin #763 and P9 staging were NOT repinned/merged.

What this DOES NOT establish: SG7 physical recovery to 77/77 and 4/4; original SIEBCU first-attempt TCP/ACSE failure cause; lossless SOE continuity or physical endurance. CI is a synthetic/integration build gate, not IEC 61850 interoperability FAT. Keep PRs Draft and issue #707 OPEN pending actual field evidence. No cyclic MMS polling or spontaneous control/RCB ownership changes were introduced.

Final dual-path validation (exact ARSAS source, 2026-11-05)

• P9 nonrelease isolated engine 58d22be43d93d1d439df04a99ba935a7ec45cd4c: CI-P1 FAST reporting #41981252170 SUCCESS: 951/951 focused reporting PASS, native bridge/CTest PASS, EXE smoke PASS, SHA-256 23b5742166605b16c1e015d0f584e1eaf936dbb2a5dac62d2d988b22c4ea2f76.
• Unchanged production engine baseline f75e323e9f8443aa20e0a3818a1d5d77255b2c0f: canonical Windows Build #41981246131 SUCCESS: 3,027/3,027 ARSAS tests PASS plus 6/6 packaged smoke checks. This is a separate pinned-engine build, not proof that its binary embeds P9.
• CI-P0 Workflow Integrity #41981246074 SUCCESS; production pin and release unchanged.

Code and nonrelease Windows trial packaging gates are fully green at source 063cf6e26c401e0586dc440adb5e646d8e74b0cd. PR remains Draft as physical SG7 77/77 + 4/4 reporting recovery is still unverified.
