rdmsm4x-changelog-20260830-1240-tyrell-task-handoff-recovery
Tyrell task state was isolated from canonical main after its Codex executor failed, preserving every uncommitted file while leaving the project recoverable.
Tyrell task handoff recovery
- Recorded: 2026-08-30T12:40:16-0400
- State-changing host:
rdmsm4x - Initiating agent:
codex@rdmpw3275m - Scope: Codex task
01a04277-a949-77f1-8f07-57ff6a8ff90f(tyrell main) and the canonical Tyrell Git worktree set onrdmsm4x - Reason: the established task failed code-mode-host negotiation three
times, including for
/bin/echo; a same-host worktree handoff was attempted to recover task execution without creating a competing project writer.
State changed
- Codex handoff operation
exec-75b1cc7b-c83f-41a1-bac3-86febe51617bcreated/Users/richh/.codex/worktrees/5a0b/Tyrell. - The new worktree uses branch
codex/tyrell-mainateff529380e8c173ada39eaaad244264078a7031c. - The previously dirty documentation/gallery delta was transferred
into that isolated worktree. Modified files observed there:
ARCHITECTURE.md,CHANGELOG.md,FEATURE_MATRIX.md,ISSUES.md,KICKOFF.md,README.md,STATUS.md,design/led-matrix/gallery/index.html,docs/brainstorm/2026-08-24-llmroo-planning-notes.md,docs/handoff-session-86816e7d-20260826.md,docs/superpowers/specs/2026-08-24-tyrell-day1-design.md, anddocs/tyrell-project.html. - Canonical
/Users/richh/dev/apps/Tyrellmainis clean at the same commit. git stash listis empty; recovery does not depend on an unnamed stash.- Existing named iOS/CloudKit worktrees and their dirty deltas were left in place.
- The Git handoff completed, but the app could not create/switch to
the destination task. The original task remains bound to
/Users/richh/dev/apps/Tyrell. - One bounded retry in the original task still failed before
/bin/echowithtimed out negotiating with the code-mode host; it made no additional Git, source, build, device, install, or deployment changes.

Recovery and undo
- Do not delete or prune
/Users/richh/.codex/worktrees/5a0b/Tyrell; it is the recovery copy for the transferred delta. - Once the Codex code-mode executor is healthy, either bind the existing task to this worktree or checkpoint the delta to a reviewed branch before any integration.
- Do not reapply the delta to canonical
mainuntil the Tyrell owner compares it with the named iOS/CloudKit worktrees and confirms one-writer ownership. - No remote branch was pushed, no release was built, and no deployment occurred.
Outstanding owner actions
- Restore/reconnect the Codex code-mode executor for the pinned Tyrell task.
- Resume verification from
/Users/richh/.codex/worktrees/5a0b/Tyrellplus the established named implementation worktrees. - Publish this changelog to Apple Notes in the
rdmsm4xfolder from an Aqua Terminal session. The initiating session is remote/background and cannot truthfully claim the Notes write.
