session_narrative: "Housekeeping + governance hardening session. Archived T-101-T-106, validated fw setup (3 bugs fixed), deep-researched inter-agent communication bus (OpenClaw, 6 frameworks, ICLR 2026), incepted then decomposed umbrella task into T-109/T-110/T-111. Added Work Proposal Rule + Task Sizing Rules to CLAUDE.md, behavioral directives to checkpoint.sh. Fixed misleading 'Task updated' message for completed tasks. 8 learnings, 1 workflow pattern."

# Session Handover: S-2026-0217-1413

## Where We Are

Framework governance significantly strengthened. 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. T-108 complete (3 onboarding bugs fixed). Three focused inception tasks ready (T-109/T-110/T-111). T-107 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 after T-108 fixes

### T-109: Structured result ledger protocol
- **Status:** started-work (inception, narrowed from umbrella task)
- **Last action:** Decomposed from original umbrella task. Now focused: YAML envelope schema + `fw bus` CLI + size gating only.
- **Next step:** Spike — 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: docs/reports/2026-02-17-agent-communication-bus-research.md

### T-110: Agent trigger via systemd.path
- **Status:** captured (inception, spawned from T-109 decomposition)
- **Last action:** Created with description and research references
- **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. Key question: can handler invoke Claude Code CLI?

### T-111: Autonomous compact-resume lifecycle
- **Status:** captured (inception, spawned from T-109 decomposition)
- **Last action:** Created with description and research references
- **Next step:** Map compact-resume lifecycle, identify mechanical vs judgment steps, prototype
- **Blockers:** None — independent of T-109/T-110
- **Insight:** User insight: compact-resume is purely mechanical, 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: "Umbrella inception" anti-pattern — 3 independent problem domains bundled into one all-or-nothing go/no-go
   - Alternatives rejected: Keep as single task (coarse progress, multi-session scope creep)

2. **Add Work Proposal Rule to CLAUDE.md (not just learnings.yaml)**
   - Why: learnings.yaml is never read by any session protocol. CLAUDE.md is loaded every session.
   - Alternatives rejected: Level 3 enforcement hook (false positives too costly)

3. **File-based result ledger over real-time message bus**
   - Why: Agents are ephemeral, no listener for real-time. PostToolUse hook provides ambient polling for free.
   - Alternatives rejected: Redis/NATS (portability), named pipes (blocks writers), SQLite (breaks YAML)

4. **Fix commit.sh "Task updated" message for completed tasks**
   - Why: Printed "T-012 updated" on every handover even though timestamp was silently skipped
   - Alternatives rejected: Search completed/ too (would update finished tasks, wrong)

## Things Tried That Failed

1. **Piping interactive answers to fw setup** — non-interactive auto-detection skips interactive prompts. Need `expect` for TTY simulation.

## Open Questions / Blockers

1. Can Claude Code CLI be invoked programmatically by a systemd service? (T-110, T-111)
2. Can prompts be injected into a running Claude Code agent? (Likely no)
3. Where should the pronunciation app directory be? (T-107)
4. testdev user on this machine needs cleanup (password redacted)

## Gotchas / Warnings for Next Session

- testdev user exists (created for testing, not cleaned up)
- T-109 was renamed from "Agent autonomy and communication architecture" to "Structured result ledger protocol"
- Research doc: docs/reports/2026-02-17-agent-communication-bus-research.md — read before T-109/T-110/T-111
- **New CLAUDE.md rules:** Work Proposal Rule + Task Sizing Rules (active governance)
- **New checkpoint.sh behavior:** Warnings now include "BUDGET:" directives

## Suggested First Action

Check context budget (`checkpoint.sh status`), then:
- **Fresh session:** T-109 (result ledger spike) — focused inception, 2h time-box, research done
- **Short session:** T-107 (pronunciation app) — user decides directory, `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), agents/git/lib/commit.sh (fix misleading message), 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→completed}/T-{101-106,108}-*.md
