session_narrative: "Housekeeping + meta-improvement session. Archived T-101-T-106, validated fw setup (found/fixed 3 bugs), deep-researched inter-agent communication (OpenClaw, industry, triggers), incepted then decomposed umbrella task into T-109/T-110/T-111. Added structural governance: Work Proposal Rule + Task Sizing Rules to CLAUDE.md, behavioral directives to checkpoint.sh. 8 learnings, 1 workflow pattern captured."

# Session Handover: S-2026-0217-1404

## Where We Are

Framework governance significantly strengthened this session. CLAUDE.md now has Work Proposal Rule (check budget before proposing work) and Task Sizing Rules (one task = one deliverable). checkpoint.sh outputs behavioral directives not just numbers. T-108 complete. Three focused inception tasks (T-109/T-110/T-111) ready for future sessions. T-107 (pronunciation app) still awaiting user directory decision.

## Work in Progress

### T-107: Initialize German pronunciation app project
- **Status:** captured — bridge task
- **Last action:** No work done (carried from S-2026-0217-1051)
- **Next step:** User decides project directory path, then `fw setup /path/to/pronunciation-app`
- **Blockers:** User decision on directory path
- **Insight:** fw setup wizard validated and bug-free (3 fixes from T-108)

### T-109: Structured result ledger protocol
- **Status:** started-work (inception, narrowed scope)
- **Last action:** Decomposed from umbrella task. Now focused only on YAML envelope schema + `fw bus` CLI + size gating. Research complete.
- **Next step:** Spike implementation — design envelope schema, implement fw bus post/read/manifest, test with simulated dispatch. Time-box: 2 hours.
- **Blockers:** None
- **Insight:** Thesis: "task-scoped file-based result ledger, not real-time bus." Research doc at docs/reports/2026-02-17-agent-communication-bus-research.md

### T-110: Agent trigger via systemd.path
- **Status:** captured (inception)
- **Last action:** Created from T-109 decomposition
- **Next step:** Spike systemd.path unit watching .context/bus/inbox/, test handler firing
- **Blockers:** None — independent of T-109
- **Insight:** systemd.path uses inotify internally, fires on PathChanged. Handler service drains inbox directory.

### T-111: Autonomous compact-resume lifecycle
- **Status:** captured (inception)
- **Last action:** Created from T-109 decomposition
- **Next step:** Map exact compact-resume lifecycle steps, identify mechanical vs judgment transitions
- **Blockers:** None — independent of T-109/T-110
- **Insight:** User's key insight: compact-resume is purely mechanical, no human judgment needed. Automating it enables indefinite agent sessions.

## Inception Phases

**4 inception task(s) pending decision** — run `fw inception status` for details.

## Gaps Register

**1 spec-reality gap(s) being watched** — see `.context/project/gaps.yaml`

- **G-004** [low]: Multi-agent collaboration untested

Run `fw audit` to check if any trigger conditions are met.

## Decisions Made This Session

1. **Decompose T-109 into 3 focused inception tasks**
   - Why: T-109 was an "umbrella inception" bundling 3 independent problem domains (result ledger, systemd triggers, autonomous lifecycle). One task = one question.
   - Alternatives rejected: Keep as single task (coarse progress, all-or-nothing go/no-go)

2. **Add Work Proposal Rule to CLAUDE.md (not just learnings.yaml)**
   - Why: learnings.yaml is "a note in a drawer nobody opens" — no session protocol reads it. CLAUDE.md is the only file every session loads.
   - Alternatives rejected: Level 3 enforcement hook (false positives too costly)

3. **Behavioral directives in checkpoint.sh warnings**
   - Why: "Context at 130K tokens" tells agent what IS; "Do not start new work" tells agent what to DO. Agents need instructions, not just metrics.
   - Alternatives rejected: Just documenting in CLAUDE.md (belt AND suspenders needed)

## Things Tried That Failed

1. **Piping interactive answers to fw setup** — non-interactive auto-detection (no TTY) triggers immediately, ignoring piped input. Correct behavior but requires `expect` for testing.

## Open Questions / Blockers

1. Can Claude Code CLI be invoked programmatically by a systemd service? (Critical for T-110, T-111)
2. Can prompts be injected into a running Claude Code agent? (Likely no — confirms pre-flight briefing model)
3. Where should the pronunciation app directory be? (T-107, user decision)
4. testdev user created on this machine but not cleaned up (password redacted)

## Gotchas / Warnings for Next Session

- testdev user exists on this machine (created for onboarding testing, needs cleanup)
- T-109 was renamed from "Agent autonomy and communication architecture" to "Structured result ledger protocol" — old name may appear in prior handovers
- Research doc at docs/reports/2026-02-17-agent-communication-bus-research.md — read before starting T-109/T-110/T-111 spikes
- **New CLAUDE.md rules this session:** Work Proposal Rule + Task Sizing Rules — these are now active governance
- 8 new learnings + 1 workflow pattern (umbrella inception anti-pattern) in project memory

## Suggested First Action

Check context budget (`checkpoint.sh status`), then:
- **Fresh session:** T-109 (result ledger spike) — focused, 2h time-box, research complete
- **Short session:** T-107 (pronunciation app) — user decides directory, then `fw setup`

## Files Changed This Session

- Created: docs/reports/2026-02-17-agent-communication-bus-research.md, .context/episodic/T-{101-106,108}.yaml, .tasks/active/T-{110,111}-*.md
- Modified: CLAUDE.md (+Task Sizing Rules, +Work Proposal Rule), agents/context/checkpoint.sh (behavioral directives), lib/setup.sh (3 bug fixes), lib/init.sh (${force:-false}), .tasks/active/T-109-*.md (narrowed scope), .context/project/{learnings,patterns}.yaml
- Moved: .tasks/active/T-{101-106,108}-*.md → .tasks/completed/
