docs: update session handoff with inst_023 details

Updated comprehensive session handoff documentation to include:
- inst_023 (Background Process Lifecycle Management) details
- Commit #4 (25e1e3d) in commits section
- Updated stats: 4 commits, 23 instructions, 7 OPERATIONAL
- Background cleanup details (killed shells + processes)
- Framework compliance updates
- Enhanced "What Worked Well" with inst_023 success

Session now properly documents both governance enhancements:
- inst_022: Automated deployment permissions
- inst_023: Background process management

Ready for next session with clean handoff.

+### 4. **25e1e3d** - Background Process Lifecycle Management (inst_023)
+**Files:** 1 changed, 29 insertions, 3 deletions
+**Deployed:** N/A (Governance rule documentation)
+
+**Background:**
+User observed orphaned npm start processes running throughout session causing:
+- Shell 9c58f4: Failed with EADDRINUSE (port 9000 already occupied)
+- Shell 44704b: Running successfully for 2.5 hours
+- Port conflicts preventing new dev server instances
+- Resource consumption across session boundaries
+
+**User Question:**
+> "I notice that there is a background task running. that may or may not be intentional. should we contemplate a rule to manage daemons/spawns on development and ensure we do not compromise session handovers"
+
+**Actions Taken:**
+1. Killed shell 44704b and orphaned npm processes
+2. Verified port 9000 freed
+3. Created inst_023 governance rule
+4. Updated instruction-history.json stats (OPERATIONAL: 6 → 7)
+
+**Governance Rule (inst_023):**
+- **Quadrant:** OPERATIONAL
+- **Persistence:** HIGH
+- **Scope:** PERMANENT
+- **Trigger:** Background processes, session handoffs
+- **Requirements:**
+  1. Document process intent before spawning
+  2. Kill non-essential processes before handoff
+  3. Check for orphaned processes at session start
+  4. Prefer foreground dev servers
+
+**Related:** inst_006 (session management protocol)

+### inst_023: Background Process Lifecycle Management
+
+**Added:** October 11, 2025 (Post-deployment)
+**Quadrant:** OPERATIONAL
+**Persistence:** HIGH
+**Temporal Scope:** PERMANENT
+
+**Text:**
+> "Background processes spawned during development sessions (dev servers, file watchers, daemons) MUST be explicitly managed: (1) Document process intent and expected lifetime before spawning, (2) Kill non-essential background processes before session handoff unless explicitly marked 'session-persistent' with justification, (3) When starting sessions, check for orphaned processes from previous sessions before spawning new ones, (4) Development servers should run in foreground when possible to avoid port conflicts and resource leaks across session boundaries."
+
+**Rationale:**
+User observed background npm start processes running throughout session (shells 9c58f4 and 44704b). Shell 9c58f4 failed with EADDRINUSE error because port 9000 was already occupied by shell 44704b, which ran for 2.5 hours. This creates: (1) Resource consumption across session boundaries, (2) Port conflicts in subsequent sessions, (3) Confusion about system state, (4) Unclear handoff expectations.
+
+**User Question:**
+"I notice that there is a background task running. that may or may not be intentional. should we contemplate a rule to manage daemons/spawns on development and ensure we do not compromise session handovers"
+
+**Cleanup Performed:**
+- Killed shell 44704b (npm start on port 9000)
+- Killed orphaned processes (PIDs 3028191, 3028219)
+- Verified port 9000 freed with `lsof -ti:9000`
+- Production server (systemd tractatus.service) remains separate and intentionally persistent
+
+**Implementation:**
+```bash
+# Before session handoff - check for background processes
+/bashes  # List all background shells
+
+# Check for orphaned processes
+lsof -ti:9000
+ps aux | grep npm | grep -v grep
+
+# Kill non-essential processes
+KillShell <shell_id>
+kill <pid>
+```
+
+**Common Culprits:**
+- `npm start` / `npm run dev`
+- `npm run watch`
+- nodemon
+- file watchers
+
+**Related:** inst_006 (session management and handoff protocol)
+**Shift:** From implicit process management to explicit lifecycle documentation
+
+**Framework Stats (After inst_023):**
+- **Total Instructions:** 23 (was 22)
+- **OPERATIONAL Quadrant:** 7 (was 6)
+- **HIGH Persistence:** 21 (was 20)
