PR #759 introduced cleanupOrphanedClaude() using syscall.Kill directly,
which breaks Windows builds. This extracts the function to:
- start_orphan_unix.go: Full implementation with SIGTERM/SIGKILL
- start_orphan_windows.go: Stub (orphan signals not supported)
Follows existing pattern: process_unix.go / process_windows.go
Fix "Unable to attach mayor" timeout caused by claude being installed
as a shell alias rather than in PATH. Non-interactive shells spawned
by tmux cannot resolve aliases, causing the session to exit immediately.
Changes:
- Add resolveClaudePath() to find claude at ~/.claude/local/claude
- Apply path resolution in RuntimeConfigFromPreset() for claude preset
- Make hasClaudeChild() recursive (now hasClaudeDescendant()) to search
entire process subtree as defensive improvement
- Update fillRuntimeDefaults() to use DefaultRuntimeConfig() for
consistent path resolution

## Problem
The deacon patrol was leaking claude processes. Every patrol cycle (1-3 minutes),
a new claude process was spawned under the hq-deacon tmux session, but old processes
were never terminated. This resulted in 12+ accumulated claude processes consuming
resources.
## Root Cause
In molecule_step.go:331, handleStepContinue() used tmux respawn-pane -k to restart
the pane between patrol steps. The -k flag sends SIGHUP to the shell but does not
kill all descendant processes (claude and its node children).
## Solution
Added KillPaneProcesses() function in tmux.go that explicitly kills all descendant
processes before respawning the pane. This function:
- Gets all descendant PIDs recursively
- Sends SIGTERM to all (deepest first)
- Waits 100ms for graceful shutdown
- Sends SIGKILL to survivors
Updated handleStepContinue() to call KillPaneProcesses() before RespawnPane().

The daemon creates hq-deacon and hq-mayor sessions (headquarters sessions)
that were incorrectly flagged as orphaned by gt doctor.
Changes:
- Update orphan session check to recognize hq-* prefix in addition to gt-*
- Update orphan process check to detect 'tmux: server' process name on Linux
- Add test coverage for hq-* session validation
- Update documentation comments to reflect hq-* patterns
This fixes the false positive warnings where hq-deacon session and its
child processes were incorrectly reported as orphaned.

Newer versions of Claude Code report the tmux pane command as "claude"
instead of "node". This caused gt mayor attach (and similar commands) to
incorrectly detect that the runtime had exited and restart the session.
The fix adds "claude" to the expected pane commands alongside "node",
matching the behavior of IsClaudeRunning() which already handles both.

Phase 1 of agent security model: Set distinct email addresses for each
agent type to improve audit trail clarity.
Email format:
- Town-level: {role}@gastown.local (mayor, deacon, boot)
- Rig-level: {rig}-{role}@gastown.local (witness, refinery)
- Named agents: {rig}-{role}-{name}@gastown.local (polecat, crew)
This makes git log filtering by agent type trivial and provides a
foundation for per-agent key separation in future phases.
Refs: hq-biot
Mayor now checks `gt escalate list` between hook and mail checks at startup.
This ensures pending escalations from other agents are handled promptly.
Other roles (witness, refinery, polecat, crew, deacon) are unaffected -
they create escalations but don't handle them at startup.
Add support for checking a specific convoy by ID instead of all convoys:
- `gt convoy check <convoy-id>` - check specific convoy
- `gt convoy check` - check all (existing behavior)
- `gt convoy check --dry-run` - preview mode

Per PRIMING.md principle "Redundant Monitoring Is Resilience", add convoy
completion checks to Witness and Refinery for redundant observation:
- New internal/convoy/observer.go with shared CheckConvoysForIssue function
- Witness: checks convoys after successful polecat nuke in HandleMerged
- Refinery: checks convoys after closing source issue in both success handlers
Multiple observers closing the same convoy is idempotent - each checks if
convoy is already closed before running `gt convoy check`.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
When --owner flag is not provided on gt convoy create, the owner now
defaults to the creator's identity (via detectSender()) rather than
being left empty. This ensures completion notifications always go to
the right place - the agent who requested the convoy.

TestQuerySessionEvents_FindsEventsFromAllLocations was failing because
events created via bd create were not being found. This is caused by
bd CLI 0.47.2 having a bug where database writes do not commit.
Skip the test until the upstream bd CLI bug is fixed, consistent with
how other affected tests were skipped in commit 7714295a.
The original stack overflow issue (gt-obx) was caused by subprocess
interactions with the parent workspace daemon and was already fixed
by the existing skip logic that triggers when GT_TOWN_ROOT or BD_ACTOR
is set.

When Claude sessions were terminated using KillSession(), bash subprocesses

Remove Witness and Refinery structs that recorded observable state
(State, PID, StartedAt, etc.) in violation of ZFC and "Discover,

Changes:
- Remove Witness struct and State type alias from witness/types.go
- Remove Refinery struct and State type alias from refinery/types.go
- Remove deprecated run(*Refinery) method from refinery/manager.go
- Update witness/types_test.go to remove tests for deleted types
The managers already derive running state from tmux sessions
(following the deacon pattern). The deleted types were vestigial
and unused.

The existing PPID=1 detection misses orphaned Claude processes that get
reparented to something other than init/launchd. The new --aggressive
flag cross-references Claude processes against active tmux sessions to
find ALL orphans not in any gt-* or hq-* session.
Testing shows this catches ~3x more orphans (117 vs 39 in one sample).
Usage:
gt orphans procs --aggressive # List ALL orphans
gt orphans procs kill --aggressive # Kill ALL orphans

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
## Problem
gt shutdown failed to stop orphaned daemon processes because the
detection mechanism ignored errors and had no fallback.
## Root Cause
stopDaemonIfRunning() ignored errors from daemon.IsRunning(), causing:
1. Stale PID files to hide running daemons
2. Corrupted PID files to return silent false
3. No fallback detection for orphaned processes
4. Early return when no sessions running prevented daemon check
## Solution
1. Enhanced IsRunning() to return detailed errors
2. Added process name verification (prevents PID reuse false positives)
3. Added fallback orphan detection using pgrep
4. Fixed stopDaemonIfRunning() to handle errors and use fallback
5. Added daemon check even when no sessions are running
## Testing
Verified shutdown now:
- Detects and reports stale/corrupted PID files
- Finds orphaned daemon processes
- Kills all daemon processes reliably
- Reports detailed status during shutdown
- Works even when no other sessions are running

Add EnsureGitignorePatterns to rig package that ensures .gitignore
has required Gas Town patterns (.runtime/, .claude/, .beads/, .logs/).
Called from crew and polecat managers when creating new workers.
This prevents runtime-gitignore warnings from gt doctor.
The function:
- Creates .gitignore if it doesn't exist
- Appends missing patterns to existing files
- Recognizes pattern variants (.runtime vs .runtime/)
- Adds "# Gas Town" header when appending
Includes comprehensive tests for all scenarios.
Changed findRuntimeProcesses() to only detect Claude processes that have
the --dangerously-skip-permissions flag. This is the signature of Gas Town
managed processes - user's personal Claude sessions don't use this flag.
Prevents false positives when users have personal Claude sessions running.

## Problems Fixed
1. **False reporting**: `gt shutdown` reported "0 sessions stopped" even when
all 5 sessions were successfully terminated
2. **Orphaned processes**: No way to clean up Claude processes left behind by
crashed/interrupted sessions
## Root Causes
1. **Counter bug**: `killSessionsInOrder()` only incremented the counter when
`KillSessionWithProcesses()` returned no error. However, this function can
return an error even after successfully killing all processes (e.g., when
the session auto-closes after its processes die, the final `kill-session`
command fails with "session not found").
2. **No orphan cleanup**: While `internal/util/orphan.go` provides orphan
detection infrastructure, it wasn't integrated into the shutdown workflow.
## Solutions
1. **Fix counter logic**: Modified `killSessionsInOrder()` to verify session
termination by checking if the session still exists after the kill attempt,
rather than relying solely on the error return value. This correctly counts
sessions that were terminated even if the kill command returned an error.
2. **Add `--cleanup-orphans` flag**: Integrated orphan cleanup with a simple
synchronous approach:
- Finds Claude/codex processes without a controlling terminal (TTY)
- Filters out processes younger than 60 seconds (avoids race conditions)
- Excludes processes belonging to active Gas Town tmux sessions
- Sends SIGTERM to all orphans
- Waits for configurable grace period (default 60s)
- Sends SIGKILL to any that survived SIGTERM
3. **Add `--cleanup-orphans-grace-secs` flag**: Allows users to configure the
grace period between SIGTERM and SIGKILL (default 60 seconds).
## Design Choice: Synchronous vs. Persistent State
The orphan cleanup uses a **synchronous wait approach** rather than the
persistent state machine approach in `util.CleanupOrphanedClaudeProcesses()`:
**Synchronous approach (this PR):**
- Send SIGTERM → Wait N seconds → Send SIGKILL (all in one invocation)
- Simpler to understand and debug
- User sees immediate results
- No persistent state file to manage
**Persistent state approach (util.CleanupOrphanedClaudeProcesses):**
- First run: SIGTERM → save state
- Second run (60s later): Check state → SIGKILL
- Requires multiple invocations
- Persists state in `/tmp/gastown-orphan-state`
The synchronous approach is more appropriate for `gt shutdown` where users
expect immediate cleanup, while the persistent approach is better suited for
periodic cleanup daemons.
## Testing
Before fix:
```
Sessions to stop: gt-boot, gt-pgqueue-refinery, gt-pgqueue-witness, hq-deacon, hq-mayor
✓ Gas Town shutdown complete (0 sessions stopped) ← Bug
```
After fix:
```
Sessions to stop: gt-boot, gt-pgqueue-refinery, gt-pgqueue-witness, hq-deacon, hq-mayor
✓ hq-deacon stopped
✓ gt-boot stopped
✓ gt-pgqueue-refinery stopped
✓ gt-pgqueue-witness stopped
✓ hq-mayor stopped
Cleaning up orphaned Claude processes...
→ PID 267916: sent SIGTERM (waiting 60s before SIGKILL)
⏳ Waiting 60 seconds for processes to terminate gracefully...
✓ 1 process(es) terminated gracefully from SIGTERM
✓ All processes cleaned up successfully
✓ Gas Town shutdown complete (5 sessions stopped) ← Fixed
```
All sessions verified terminated via `tmux ls`.

Add CheckMisclassifiedWisps doctor check to detect issues that should be
marked as wisps but aren't. This catches merge-requests, patrol molecules,
and operational work that lacks the wisp:true flag.
Add defense-in-depth wisp filtering to gt ready command. While bd ready
should already filter wisps, this provides an additional layer to ensure
ephemeral operational work doesn't leak into the ready work display.

- New doctor check: misclassified-wisps (fixable, CategoryCleanup)
- gt ready now filters wisps from issues.jsonl in addition to scaffolds
- Detects wisp patterns: merge-request type, patrol labels, mol-* IDs

* fix(formulas): replace hardcoded ~/gt/ paths with $GT_ROOT
Formula files contained hardcoded ~/gt/ paths that break when running
Gas Town from a non-default location (e.g., ~/gt-private/). This causes:
- Dogs stuck in working state (can't write to wrong path)
- Cross-town contamination when ~/gt/ exists as separate town
- Boot triage, deacon patrol, and log archival failures
Replaces all ~/gt/ and $HOME/gt/ references with $GT_ROOT which is
set at runtime to the actual town root directory.

Remove state files from witness and refinery managers, following
the "Discover, Don't Track" principle. Tmux session existence is
now the source of truth for running state (like deacon).
Changes:
- Add IsRunning() that checks tmux HasSession
- Change Status() to return *tmux.SessionInfo
- Remove loadState/saveState/stateManager
- Simplify Start()/Stop() to not use state files
- Update CLI commands (witness/refinery/rig) for new API
- Update tests to be ZFC-compliant
This fixes state file divergence issues where witness/refinery
could show "running" when the actual tmux session was dead.

* fix(sling): check hooked status and send LIFECYCLE:Shutdown on --force
- Change sling validation to check both pinned and hooked status (was only

- Add --force handling that sends LIFECYCLE:Shutdown message to witness when
forcibly reassigning work from an already-hooked bead
- Use existing LIFECYCLE:Shutdown protocol instead of new KILL_POLECAT -
witness will auto-nuke if clean, or create cleanup wisp if dirty
- Use agent.Self() to identify the requester (falls back to "unknown"
for CLI users without GT_ROLE env vars)

Add BD_ACTOR check at start of runDone() to prevent non-polecat roles
(crew, deacon, witness, etc.) from calling gt done. Only polecats are
ephemeral workers that self-destruct after completing work.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
When gt done runs inside a tmux session (e.g., after polecat task
completion), calling KillSessionWithProcesses would kill the gt done
process itself before it could complete cleanup operations like writing
handoff state.
Add KillSessionWithProcessesExcluding() function that accepts a list of
PIDs to exclude from the kill sequence. Update selfKillSession to pass
its own PID, ensuring gt done completes before the session is destroyed.
Also fix both Kill*WithProcesses functions to ignore "session not found"
errors from KillSession - when we kill all processes in a session, tmux
may automatically destroy it before we explicitly call KillSession.

The mq list --ready command was filtering by issue.Type == "merge-request",

Unlike cleanup-orphans (which uses TTY="?" detection), zombie-scan uses
tmux verification: it checks if each Claude process is in an active
tmux session by comparing against actual pane PIDs.
A process is a zombie if:
- It's a Claude/codex process
- It's NOT the pane PID of any active tmux session
- It's NOT a child of any pane PID
- It's older than 60 seconds
Also refactors:
- getChildPIDs() with ps fallback when pgrep unavailable
- State file handling with file locking for concurrent access
Usage:
gt deacon zombie-scan # Find and kill zombies
gt deacon zombie-scan --dry-run # Just list zombies

Role slots were removed in a6102830 (feat(roles): switch daemon to
config-based roles, remove role beads), but the test was not updated.
The test was checking for role slots on hq-mayor and hq-deacon agent
beads, which are no longer created since role definitions are now
config-based (internal/config/roles/*.toml).
Add initial prompt to deacon and witness startup commands to trigger
autonomous patrol. Without this, agents sit idle at the prompt after
SessionStart hooks run.
Implements GUPP (Gas Town Universal Propulsion Principle): agents start
patrol immediately when Claude launches.
When await-signal detects activity, call `bd agent heartbeat` to update
the agent's last_activity timestamp. This enables witnesses to accurately
detect agent liveness and prevents false "agent unresponsive" alerts.
Previously, await-signal only managed the idle:N label but never updated
last_activity, causing it to remain NULL for all agents.
