Summary:
Implemented the Windows ownership publication fix.

Key changes:

• Added monotonic Generation and explicit AuthorityState fields.
• Added bounded AUTHORITY_PUBLICATION phase; OWNERSHIP_CAPTURE is observable only after durable commit and re-read.
• Uses same-directory MoveFileExW with REPLACE_EXISTING | WRITE_THROUGH.
• Validates schema, identities, Boolean types, generation, installer authority, and complete resource authority.
• Preserves canonical authority on partial writes, stale generations, collisions, or interruption.
• Supports cleanup retry from a byte-identical flushed receipt.
• Added Windows regressions for stale generation, partial collision, flush-before-rename recovery, and retry.

Files include test-installed-windows-app.ps1, cleanup-installed-windows-app.ps1, and supervisor fixtures/tests.

Validation:

• Release workflow suite: 23/23 passed.
• Full desktop suite: 177 passed, 6 platform-specific skips.
• Native PowerShell regressions require the Windows x64/ARM64 CI jobs.

Ultrafix follow-up on exact head 2be43cc. Keep the production authority-publication ordering and all existing F10-F24 semantics, but close the independent deterministic-proof gap.

Add a controlled helper-process test matrix covering process death immediately before authority publication, during durable publication, and immediately after committed publication. The DURING case must exercise the real durability sequence: the child writes the .new authority record with FileStream WriteThrough, calls Flush(true), signals the parent only after that flush, and the parent kills the child before the atomic rename/replace. Then invoke the real cleanup/controller path and prove that it resumes only the byte-identical exact next generation. Also prove that partial, foreign, stale, or generation-mismatched .new records are rejected and that the exact authorized tree is cleaned without widening path/deletion/identity authority.

Do not substitute WriteAllText or an in-process exception for process death and durable flush evidence. Preserve schema v3 identifiers, NONPROVISIONAL/COMMITTED reread requirements, startup classifications, fixed protocol output, and existing deletion rules. Run the deterministic Windows tests on both x64 and ARM64 where the workflow supports them, plus static tests/typecheck, and report the exact new head.

Summary of Changes

Implemented the deterministic publication-death proof without committing.

Key changes:

• Added real cleanup-worker process-death gates for BEFORE, DURING, and AFTER publication in cleanup-installed-windows-app.ps1.
• DURING signals only after FileStream WriteThrough, Flush(true), and close, before atomic replacement.
• Added byte-identical recovery and partial/foreign/stale/generation-mismatched .new rejection tests in test-installed-windows-app-supervisor.ps1.
• Added static ordering and matrix guards in release-workflow.test.ts.
• Existing workflow coverage already runs the deterministic suite on native Windows x64 and ARM64.

Validation:

• Desktop suite: 177 passed, 6 platform-specific skips.
• Release workflow tests: 23/23 passed.
• Desktop typecheck: passed.
• git diff --check: passed.
• Native Windows execution awaits the configured x64/ARM64 CI runners.

Per instruction, no commit was created. Exact current HEAD remains 2be43cc6b717c6c1cc9ae2a4156792efd5069898; the system-generated new head is not available until it commits these changes.
