rdmsm4x-changelog-20260902-2213-tyrell-reboot-pause

Paused Tyrell work at Rich's request and preserved every active lane with an exact reboot-resume checkpoint so no dirty source or acceptance boundary is lost.

Scope and files

• Interrupted the two active root-managed subagents; no new work remains running.
• Preserved clean Build 15 integration worktree at 0ab333d57beef431e97ac35188a38a0a38371aab.
• Preserved clean independently accepted menu-bar worktree at 5c42446d16dac7c50c62efae8e8915ef47f17be4.
• Preserved four uncommitted Build 16 iOS correction files in /Users/richh/dev/_worktrees/tyrell-build16-ios-lifecycle-20260902 over 3d834cf53fb1f2fd5050368c22ac5d1d27bbb8ff.
• Updated the implementation and review check-ins under /Users/richh/.agent-coordination/checkins/ to paused_for_user_reboot states.
• Created reboot pointer: /Users/richh/dev/_handoff/tyrell-reboot-resume-20260902-2213.md
• Pointer SHA-256: e4910d38ceed761ba8eab15589bb53af76bff4b740917de963eea1b204baa20a

Verification

• All three worktree HEADs and dirty states were re-read after interruption.
• The Build 16 dirty path list contains exactly four owned files.
• Its unstaged diff SHA-256 is eefabd677671e9919aa0a9d72f97ac3bea1fb2f30b6c9e0396b06e9f7426a28e.
• git diff --check passed for the dirty correction.
• No disposable Tyrell Build 15/16 simulator was present.
• No root-managed test or build command remained active.
• Both paused check-in JSON files validated and synchronized to all five peers.

Undo and resume

No runtime was changed and no backup was needed. Do not reset, stash, clean, or overwrite the dirty Build 16 worktree. Resume from the reboot pointer, first closing its reachability lifetime, lost configuration-follow-up race, and child task cancellation findings. Separately integrate the reviewed menu-bar candidate onto a successor of the clean Build 15 checkpoint. Build 11 remains the accepted fleet rollback.
