fix(session): increase ClaudeStartTimeout from 60s to 120s

Fixes intermittent 'timeout waiting for runtime prompt' errors that occur
when Claude takes longer than 60s to start under load or on slower machines.

Resolves: hq-j2wl

 ## [Unreleased]
 
+## [0.4.0] - 2026-01-17
+
+### Fixed
+
+- **Orphan cleanup skips valid tmux sessions** - `gt orphans kill` and automatic orphan cleanup now check for Claude processes belonging to valid Gas Town tmux sessions (gt-*/hq-*) before killing. This prevents false kills of witnesses, refineries, and deacon during startup when they may temporarily show TTY "?"
+
+## [0.3.1] - 2026-01-17
+
+### Fixed
+
+- **Orphan cleanup on macOS** - Fixed TTY comparison (`??` vs `?`) so orphan detection works on macOS
+- **Session kill leaves orphans** - `gt done` and `gt crew stop` now use `KillSessionWithProcesses` to properly terminate all child processes before killing the tmux session

+1. **CRITICAL: Close steps in real-time** - Mark `in_progress` BEFORE starting, `closed` IMMEDIATELY after completing. Never batch-close steps at the end. Molecules ARE the ledger - each step closure is a timestamped CV entry. Batch-closing corrupts the timeline and violates HOP's core promise.

+Clean up orphaned claude subagent processes.
+
+Claude Code's Task tool spawns subagent processes that sometimes don't clean up

+
+**Detection method:**

+instances in terminals have a TTY like "pts/0".
+
+**Run cleanup:**
+```bash
+gt deacon cleanup-orphans

+1. Lists all claude/codex processes with `ps -eo pid,tty,comm`
+2. Filters for TTY = "?" (no controlling terminal)
+3. Sends SIGTERM to each orphaned process
+4. Reports how many were killed
+
+**Why this is safe:**
+- Processes in terminals (your personal sessions) have a TTY - they won't be touched
+- Only kills processes that have no controlling terminal
+- These orphans are children of the tmux server with no TTY, indicating they're
+  detached subagents that failed to exit

 ### Communication
-- `gt mail send <addr> -s "Subject" -m "Message"` - Send mail
+- `gt mail send <addr> -s "Subject" -m "Message"` - Send mail (async, queued)
 - `gt mail send mayor/ -s "Subject" -m "Message"` - To Mayor
 - `gt mail send --human -s "Subject" -m "Message"` - To overseer
+- `gt nudge <target> "message"` - Wake an agent and send immediate message
+
+### gt nudge: Waking Agents
+
+`gt nudge` is the **core mechanism for inter-agent communication**. It sends a message
+directly to another agent's Claude Code session via tmux.
+
+**When to use nudge vs mail:**
+| Use Case | Tool | Why |
+|----------|------|-----|
+| Wake a sleeping agent | `gt nudge` | Immediate delivery to their session |
+| Send task for later | `gt mail send` | Queued, they'll see it on next check |
+| Both: assign + wake | `gt mail send` then `gt nudge` | Mail carries payload, nudge wakes them |
+
+**Common patterns:**
+```bash
+# Wake another crew member (full path: rig/crew/name)
+gt nudge {{ .RigName }}/crew/peer "Check your mail - PR review waiting"
+
+# Wake a polecat (full path: rig/polecats/name)
+gt nudge {{ .RigName }}/polecats/alpha "Work available on hook"
+
+# Nudge with notification flag (also sends tmux bell)
+gt mail send {{ .RigName }}/peer -s "Urgent" -m "..." --notify
+
+# Nudge patrol agents
+gt nudge witness "Check polecat health"
+gt nudge deacon "Session started"
+gt nudge mayor "Status update needed"
+```
+
+**Target shortcuts:**
+- `mayor` → gt-mayor session
+- `deacon` → gt-deacon session
+- `witness` → gt-{{ .RigName }}-witness session
+- `refinery` → gt-{{ .RigName }}-refinery session
+- `channel:<name>` → All members of a named channel
+
+**Important:** `gt nudge` is the ONLY reliable way to send text to Claude sessions.
+Raw `tmux send-keys` is unreliable. Always use `gt nudge` for agent-to-agent communication.

+### 🚨 THE BATCH-CLOSURE HERESY 🚨
+
+Molecules are the **LEDGER** - not a task checklist. Each step closure is a timestamped entry in your permanent work record (your CV).
+
+**The discipline:**
+1. Mark step `in_progress` BEFORE starting it: `bd update <step-id> --status=in_progress`
+2. Mark step `closed` IMMEDIATELY after completing it: `bd close <step-id>`
+3. **NEVER** batch-close steps at the end
+
+**Why this matters:** Batch-closing corrupts the timeline. It creates a lie - showing all steps completed at the same moment instead of the actual work progression. The activity feed should show your REAL work timeline.
+
+**Wrong:** Do all work, then close steps 1, 2, 3, 4, 5 in sequence at the end
+**Right:**
+- Mark step 1 in_progress → do work → close step 1
+- Mark step 2 in_progress → do work → close step 2
