The gt namepool add command was replacing custom_names instead of
appending because it saved to the runtime state file, but Load()
intentionally ignores CustomNames from that file (expecting config
to come from settings/config.json).
Changes:
- runNamepoolAdd now loads existing settings, appends the new name,
and saves to settings/config.json (the source of truth)
- runNamepoolSet now preserves existing custom names when changing
themes (was passing nil which cleared them)
- Added duplicate check to avoid adding same name twice

When running from a crew workspace, BEADS_DIR is set to the rig's beads
directory. This caused auto-convoy creation to fail because bd would use
the rig's database (prefix=bd) instead of discovering the HQ database
(prefix=hq) from the working directory.
The fix clears BEADS_DIR from the environment when running bd commands
for convoy creation, allowing bd to discover the correct database from
the townBeads directory.

Convoy beads use hq-cv-* IDs for visual distinction from other town beads.
The routes.jsonl entry was being added but allowed_prefixes config was not,
causing bd create --id=hq-cv-xxx to fail prefix validation.
This adds the allowed_prefixes config (hq,hq-cv) during initTownBeads so
convoy creation works out of the box after gt install.

Formula scaffold beads (created when formulas are installed) were
appearing as actionable work items in `gt ready`. These are template
beads, not actual work.
Add filtering to exclude issues whose ID:
- Matches a formula name exactly (e.g., "mol-deacon-patrol")
- Starts with "<formula-name>." (step scaffolds like "mol-deacon-patrol.inbox-check")
The fix reads the formulas directory to get installed formula names
and filters issues accordingly for both town and rig beads.

* feat: Add automatic orphaned claude process cleanup
Claude Code's Task tool spawns subagent processes that sometimes don't clean up
properly after completion. These accumulate and consume significant memory
(observed: 17 processes using ~6GB RAM).
This change adds automatic cleanup in two places:
1. **Deacon patrol** (primary): New patrol step "orphan-process-cleanup" runs
`gt deacon cleanup-orphans` early in each cycle. More responsive (~30s).
2. **Daemon heartbeat** (fallback): Runs cleanup every 3 minutes as safety net
when deacon is down.
Detection uses TTY column - processes with TTY "?" have no controlling terminal.
This is safe because:
- Processes in terminals (user sessions) have a TTY like "pts/0" - untouched
- Only kills processes with no controlling terminal
- Orphaned subagents are children of tmux server with no TTY
New files:
- internal/util/orphan.go: FindOrphanedClaudeProcesses, CleanupOrphanedClaudeProcesses
- internal/util/orphan_test.go: Tests for orphan detection
New command:
- `gt deacon cleanup-orphans`: Manual/patrol-triggered cleanup

* fix(orphan): add Windows build tag and minimum age check
Addresses review feedback on PR #588:
1. Add //go:build !windows to orphan.go and orphan_test.go
- The code uses Unix-specific syscalls (SIGTERM, ESRCH) and
ps command options that don't exist on Windows
2. Add minimum age check (60 seconds) to prevent false positives
- Prevents race conditions with newly spawned subagents
- Addresses reviewer concern about cron/systemd processes
- Uses portable etime format instead of Linux-only etimes
3. Add parseEtime helper with comprehensive tests
- Parses [[DD-]HH:]MM:SS format (works on both Linux and macOS)
- etimes (seconds) is Linux-specific, etime is portable
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* fix(orphan): add proper SIGTERM→SIGKILL escalation with state tracking
Previous approach used process age which doesn't work: a Task subagent
runs without TTY from birth, so a long-running legitimate subagent that
later fails to exit would be immediately SIGKILLed without trying SIGTERM.
New approach uses a state file to track signal history:
1. First encounter → SIGTERM, record PID + timestamp in state file
2. Next cycle (after 60s grace period) → if still alive, SIGKILL
3. Next cycle → if survived SIGKILL, log as unkillable and remove
State file: $XDG_RUNTIME_DIR/gastown-orphan-state (or /tmp/)
Format: "<pid> <signal> <unix_timestamp>" per line
The state file is automatically cleaned up:
- Dead processes removed on load
- Unkillable processes removed after logging
Also updates callers to use new CleanupResult type which includes
the signal sent (SIGTERM, SIGKILL, or UNKILLABLE).

* fix(mq): skip closed MRs in list, next, and ready views (gt-qtb3w)
The gt mq list command with --status=open filter was incorrectly displaying
CLOSED merge requests as 'ready'. This occurred because bd list --status=open

Added manual status filtering in three locations:
- mq_list.go: Filter closed MRs in all list views
- mq_next.go: Skip closed MRs when finding next ready MR
- engineer.go: Skip closed MRs in refinery's ready queue
Also fixed build error in mail_queue.go where QueueConfig struct (non-pointer)

The help text claimed 'gt mail read' marks messages as read, but this

Update the help text to accurately reflect the current behavior and
point users to 'gt mail mark-read' for explicit read marking.
When gt doctor runs, it now detects and kills zombie sessions - tmux
sessions that are valid Gas Town sessions (gt-*, hq-*) but have no
Claude/node process running inside. These occur when Claude exits or

Previously, OrphanSessionCheck only validated session names but did not
check if Claude was actually running. This left empty sessions
accumulating over time.

When using `gt sling <formula> --on <bead>`, the wisp was bonded to the
target bead but the attached_molecule field wasn't being set in the
bead's description. This caused `gt hook` to report "No molecule
attached" even though the formula was correctly bonded.
Now both sling.go (--on mode) and sling_formula.go (standalone formula)
call storeAttachedMoleculeInBead() to record the molecule attachment
after wisp creation. This ensures gt hook can properly display molecule
progress.

Branch names like "polecat/furiosa-mkb0vq9f" don't contain the actual
issue ID, causing gt done to incorrectly parse "furiosa-mkb0vq9f" as the
issue. This broke integration branch auto-detection since the wrong issue
was used for parent epic lookup.
Changes:
- After parsing branch name, check the agent's hook_bead field which
contains the actual issue ID (e.g., "gt-845.1")
- Fix parseBranchName to not extract fake issue IDs from modern polecat branches
- Fix detectIntegrationBranch to traverse full parent chain (molecule → bug → epic)
- Include issue ID in polecat branch names when HookBead is set
Added tests covering:
- Agent hook returns correct issue ID
- Modern polecat branch format parsing
- Integration branch detection through parent chain

IsSilentExit used type assertion which fails on wrapped errors.
Changed to errors.As to properly unwrap and detect SilentExitError.
Added test to verify wrapped error detection works.
The stop hook runs 'gt costs record' which executes 'bd create' to
record session costs. When run from a role subdirectory (e.g., mayor/)
that doesn't have its own .beads database, bd fails with:
'database not initialized: issue_prefix config is missing'
Fix by using workspace.FindFromCwd() to locate the town root and
setting bdCmd.Dir to run bd from there, where the .beads database
exists.

Add SessionSet type to tmux package for O(1) session existence checks.
Instead of calling HasSession() (which spawns a subprocess) for each
rig/session during shutdown, now calls ListSessions() once and uses
in-memory map lookups.

- internal/cmd/down.go: Use SessionSet for dry-run checks and session stops
- internal/session/town.go: Add StopTownSessionWithCache() variant
