   Implementation checkpoint against Pylon 00b2ffc23f0a945bbf658de40acae281ae2fd69d; frozen upstream head unchanged.

   • fix(antigravity): avoid spawning runtimes for health checks #586 Antigravity health/temp ownership: head 7f57442be7; 61 focused tests, server typecheck/lint pass. CI green at this checkpoint. Excludes unsafe blanket startup sweep; abrupt termination may leave runtime temp directories.
   • fix(checkpoints): publish durable refs and preserve captured state #588 checkpoint durability/projection: head 2087600460; 57 focused tests including real capture/restore, server typecheck/lint pass. Preserve Pylon capture path; no unrelated sparse-index optimization.
   • fix(clients): prevent duplicate startup and preserve cached history #589 desktop startup/cached history: head 8f71409ba9; 37 focused tests, desktop/client-runtime/web typechecks and lint pass. #11958 covered by absent custom paste dispatch, not imported.
   • fix(server): keep Git waits off provider lifecycle ingestion #590 Git/turn responsiveness: head 41a964aee7; 175 focused tests, server typecheck/lint pass. Confirmed diffs re-enter Pylon runtime/Stop/incarnation fences; regression covers retirement while detection is pending. The upstream new-turn-after-failure test now makes a user admission, matching Pylon's lifecycle rules.

   CI is being checked on the remaining heads. These four PRs are not merged; the approval to merge #583 has already been fulfilled and is not treated as blanket approval for these new PRs. No release/installation performed. Each PR carries source attribution and a compact ledger entry. The global review cursor remains unchanged.

   Remaining review groups after this bounded sequence: durable worktree setup/follow-ups, provider/chat features, source-control improvements, broader UI/mobile work, and the coordinated distribution series described in the initial inventory. No new upstream fetch expands the frozen range.

   All four implementation PRs now have green active CI checks on their current heads, with no submitted review findings:

   PR	Final checked head	Focused tests
   #586 Antigravity health/temp ownership	7f57442be7bc7f9975dbaa25f457e3436d6c98a2	61
   #588 Checkpoint durability/projection	2087600460e2fa99a466ee20fc02341ce61cbe87	57
   #589 Desktop startup/cached history	8f71409ba90cebab039609233cab0e3aae3f0700	37
   #590 Git/turn responsiveness	41a964aee7174f60462b11d4c4b2ce476ed6cf94	175

   330 focused tests pass in total, plus the scoped typechecks/lint and CI. Seven sources are implemented and one paste-fix source is covered by Pylon's absent custom dispatch path. The PRs await developer merge approval. Merge through PRs, resolve any ledger-only conflicts while preserving all records, and require checks on any updated head. No release or installation performed; review cursor unchanged.

   The isolated notification verification servers and browser from #583 have been stopped; reproduction state and uploaded evidence are preserved. Implementation worktrees are clean and remain available. No new backend is running for these four batches.

   Completed with developer merge approval and green final-head checks:

   • fix(antigravity): avoid spawning runtimes for health checks #586 Antigravity installation-only health probes and owned runtime temporary directories. Merge 5dad0b0cba0752f0e90dbe0eb7745d2f793f1c5e.
   • fix(checkpoints): publish durable refs and preserve captured state #588 Durable checkpoint objects/refs and monotonic checkpoint projection. Merge ad808bf7920647d3df0ebcb1674f94d006d24c26.
   • fix(clients): prevent duplicate startup and preserve cached history #589 Single desktop startup and cached history/pagination recovery. Merge eb61689f842dead7c036056c51297cea1199c7ef.
   • fix(server): keep Git waits off provider lifecycle ingestion #590 Bounded short Git command concurrency and diff detection outside lifecycle ingestion, retaining Pylon admission/Stop/runtime fences. Merge 1eedd6713c0ebeffb25490fb842e4c95cf5109be.

   330 focused regressions passed during implementation, with scoped types and lint. After #586 landed, the remaining branches were rebased in dependency order; only the upstream review log conflicted, and all entries were retained. Range comparisons confirmed unchanged implementation patches. All refreshed CI checks passed, including Linux/Windows packaged desktop smoke. The final merged product tree exactly matches the tested #590 head 65586a2dd5fbcdaad9fc8cee65e436e8550e9835.

   Original source authorship and cherry-pick source references are preserved through merge commits. Seven bounded upstream sources were adopted; the paste source is covered by Pylon's absence of the duplicate custom dispatch. All eight sources in this issue have a disposition. Task branches were removed; isolated worktrees retained detached and clean.

   The broader frozen review remains incomplete and its global cursor is unchanged. This closes only the approved reliability/client-recovery batch. No release or installation was performed.
