session_narrative: "Deep review of T-151/T-184 (cron audit system) revealed agent completed spec without human consultation. Human introduced ISO 27001 four-level assurance model. Created T-194 inception. Diagnosed 7 existing research persistence controls — all failed. Designed and built 3 new controls (C-001 live doc, C-002 commit gate, C-003 checkpoint prompt) with OE tests. Experiment running on T-194 itself. About to start Phase 1 (risk landscape)."

# Session Handover: S-2026-0219-1711

## Where We Are

T-194 inception (ISO 27001-aligned assurance model) is in Phase 0 — genesis, failure analysis, and experiment setup complete. Three research persistence controls (C-001/C-002/C-003) built and deployed with OE tests running in cron. Phase 1 (risk landscape) is next. T-151/T-184 parked (horizon: later) — subsumed by T-194's broader scope.

## Work in Progress

<!-- horizon: now -->

### T-194: "ISO 27001-aligned assurance model — control register, OE testing, risk-driven cron redesign"
- **Status:** started-work (horizon: now)
- **Last action:** Built and deployed C-001 (CLAUDE.md rule), C-002 (commit-msg hook warning), C-003 (checkpoint.sh prompt), OE tests (audit.sh Section 11), cron integration
- **Next step:** Phase 1 — Risk landscape mapping (identify risks, map controls to risks, design risk register)
- **Blockers:** None
- **Insight:** 7 existing controls for research persistence all failed (post-hoc, advisory, scope-limited, or unused). Control Design ≠ Operational Effectiveness. First OE test already caught T-190 missing research artifact.

### T-190: "Investigate sub-agent research persistence"
- **Status:** started-work (horizon: now)
- **Last action:** Flagged by T-194 C-001 OE test — no research artifact in docs/reports/
- **Next step:** May be subsumed by T-194 (which addresses the broader research persistence problem)
- **Blockers:** None
- **Insight:** T-194's failure analysis covers T-190's scope and more (main-thread + sub-agent)

### T-191: "Component Fabric — structural topology system"
- **Status:** started-work (horizon: now)
- **Last action:** Phase 1 complete (previous sessions). Untouched this session.
- **Next step:** Phase 2 — Use case deep dives
- **Blockers:** None
- **Insight:** N/A this session

### T-193: "Implement P-010 AC tagging — agent/human verification split"
- **Status:** captured (horizon: now)
- **Last action:** Task created (previous session). Untouched this session.
- **Next step:** Start implementation — modify update-task.sh P-010 gate
- **Blockers:** None
- **Insight:** N/A this session

<!-- horizon: later -->

### T-151: "Investigate audit tasks as cronjobs"
- **Status:** started-work (horizon: later) — PARKED
- **Last action:** Reopened from completed, reviewed, parked. Subsumed by T-194.
- **Next step:** Revisit after T-194 GO decision — may be closed or restructured
- **Blockers:** T-194 outcome determines T-151's future
- **Insight:** Was completed by agent in 2 minutes without human consultation. Specification task with owner: human should have required dialogue.

### T-184: "Implement cron-based audit scheduling (T-151 GO)"
- **Status:** started-work (horizon: later) — PARKED
- **Last action:** Reopened from completed, parked. Implementation will be redesigned per T-194.
- **Next step:** Revisit after T-194 GO — cron schedule will be redesigned around OE testing
- **Blockers:** T-194 outcome
- **Insight:** Current cron reruns structural checks. Should be redesigned as OE testing per ISO 27001 Level 3.

## Inception Phases

**3 inception task(s) pending decision** — T-190, T-191, T-194.

T-194 is in Phase 0 (complete) → Phase 1 (next). Experiment controls deployed and running.

## 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. **New inception (T-194) instead of fixing T-151/T-184**
   - Why: T-151 was the wrong shape — "cron the audits" treats symptoms. The real gap is assurance structure: risk → control → OE → audit.
   - Alternatives rejected: (a) Fix cron frequencies, (b) Add OE tests to existing cron without risk model

2. **ISO 27001 four-level model as framework for AEF assurance**
   - Why: Human's expertise — provides proven structure for what we were building organically. Risk → Control Design → Operational Effectiveness → Audit.
   - Alternatives rejected: Continue ad-hoc control building

3. **Three controls (D+F+B) for research persistence experiment**
   - Why: Different types (behavioral + gate + checkpoint) test which enforcement level works. D proven by T-191, F adds structural backup, B adds periodic awareness.
   - Alternatives rejected: Single control only — can't compare effectiveness

4. **Define OE tests BEFORE building controls**
   - Why: T-185 built controls without OE tests → all 7 failed. ISO 27001 principle: if you can't test it, don't build it.
   - Alternatives rejected: Build first, test later

5. **Human dialogue mandatory for every inception phase**
   - Why: T-151 completed by agent in 2 minutes without human on a human-owned spec task. Structural prevention.
   - Alternatives rejected: Agent research with human review at end

## Things Tried That Failed

Nothing failed this session — clean analysis and build.

## Open Questions / Blockers

1. Does `gaps.yaml` become the risk register, or do we need a separate `risks.yaml`?
2. What risk categories make sense for a software governance framework (vs infosec)?
3. Should T-190 be closed as subsumed by T-194, or kept as a separate narrower scope?
4. How granular should the control register be? (per-script? per-function? per-rule?)

## Gotchas / Warnings for Next Session

- C-002 (commit gate) only warns, doesn't block — warnings logged to `.context/working/.inception-research-warnings`
- C-003 (checkpoint) fires every 20 tool calls — watch for noise level
- T-151/T-184 are parked in active/ (horizon: later) but still show in task lists — don't work on them
- `fw audit --section oe-research` runs the new OE checks — useful for spot-checking
- Hooks snapshot at session start — the C-002 commit-msg change is already in .git/hooks/ (not via install-hooks), so it's active

## Suggested First Action

Continue T-194 Phase 1 — Risk landscape mapping. Start by identifying risk categories for AEF governance, then map existing controls to risks. Dialogue with human required.
