# Session Close — 2026-04-28

**The day Step 3 of the mandatory stack closed in one calendar
day.** This capsule is for tomorrow-Joe — a single source of
truth for "what shipped today, what's still pending, what's
next."

---

## What shipped

- **Step 3: Path C codeless schema surgery — CLOSED**
- Tag: `v3.4.0-path-c` on commit `3560a43` (Mile 3 close)
- PR #2: https://github.com/JosephOIbrahim/Harlo/pull/2
  (state: **OPEN**, mergeable: **MERGEABLE**, mergeStateStatus:
  **CLEAN**, CI: **CodeRabbit SUCCESS**)
- Branch: `harness-path-c` (**12 commits** since master)

### Test baseline lineage
- D14 (Mile 1 cited): 1,140 (unverified)
- Phase 0 measured: 1,065 (missing dev deps)
- Phase A resolved: 1,133 (D14 amended)
- Mile 3 final: **1,172**
- Net change Mile 1 → Mile 3: **+39** tests, zero regressions

### Latency
- Phase 0 baseline: p50 4,347 µs / p95 4,785 µs
- Mile 3 final:    p50 4,098 µs / p95 4,592 µs
- Delta: **−5.73% / −4.05%** (improved within run-to-run variance;
  runtime tier was never modified)

### Decisions logged
- D1–D5 in `harness/path_c/05_DECISIONS.md`
- D6–D14 in `harness/path_c/06_DECISIONS_PHASE_1.md`
- D15–D19 in `harness/path_c/07_DECISIONS_PHASE_4.md`
- **19 decisions total. Zero conflicts.**

### Crucible gates
- **8/8 phase gates passed** (verify/ artifacts: phases 0, 1, 2,
  3, 4, 5, 6, plus Mile 3 final audit)
- Final audit: `verify/mile_3_final_crucible.md`

### README diagrams
- 3 Path C Mermaid diagrams in **true duotone**
  (substrate **navy** `#1a2332/#4a90a4/#e8eef2` +
   runtime **brass** `#d4af37/#8b7115/#1a2332` —
   2 classes per diagram, no slate)
- 5 pre-existing v3.3.1 diagrams retained (System Layers,
  Exchange Loop, State Machines, Hydra Delegate Pattern,
  Prediction Pipeline — still accurate post-Path-C)

## What's pending tomorrow-you

1. **Visual review of PR #2** — confirm 3 duotone diagrams render
   correctly in GitHub's Mermaid preview at
   https://github.com/JosephOIbrahim/Harlo/pull/2
2. **CodeRabbit:** already SUCCESS. Surface any inline comments
   it left as PR review.
3. **Merge PR #2** — once visual review green. The PR is
   already MERGEABLE / CLEAN.
4. **Optional: delete `harness-path-c`** after merge (manual UI
   action; agent does not delete branches).
5. **Branch protection ruleset** — master ruleset exists with
   target=branch but **enforcement=disabled**. Rules
   *intended* (per session memory):
     - Restrict deletions
     - Block force pushes
     - Require PR before merging (0 approvals — solo)
     - Require linear history
   To activate: GitHub UI → Repo Settings → Rules → Rulesets →
   master → Status: Active. Currently it's a draft ruleset
   that's not protecting anything.

## What's next (Step 4)

**Step 4: ComfyCozy × Moneta demo** is the next item in the
mandatory stack. Different shape than Step 3:

- Wire-up + recording, not surgery
- ComfyCozy frozen as law (no edits to its repo)
- Moneta speaks real USD; Harlo now speaks real USD too —
  bridge-free interop possible
- Estimated wall-clock: ~1.5 weeks
- Send window: opens 2026-06-02 (5 weeks out)
- D1 cap (2026-05-15) **cleared by 17 days** by today's close

When ready: open a fresh chat session, share this capsule, ask
for a Step 4 prompt. Different harness shape — that one needs
scoping for ComfyCozy's existing event surface and Moneta's
repo path access (Moneta repo confirmed at `C:\Users\User\Moneta`
during today's Phase 2 scout).

---

## What's deferred (post-Step-6)

- `opinion_json` typed migration (D8) — `CompositionLayerPrim.opinion`
  stays string sidecar
- `answer_embeddings_json` typed migration (D9) — `IntakeHistoryPrim.answer_embeddings`
  stays string sidecar
- `InjectionPrim` cross-session persistence (D5) — session-scoped only
- `src/cognitive_stage.py` Sprint 4 rewire (D6 stay-separate) —
  Sprint 4 code preserved, dormant under Path C

These are not yet filed as TIs in
`harness/path_c/tracking_issues.md` (only TI-001 lives there,
RESOLVED-ON-ARRIVAL). When any of them is revisited, file as
TI-002 / TI-003 / etc. at that point — premature filing adds
overhead.

## Patent posture

P1 (USD Substrate) CIP framing **now defensible**. Public Apache
2.0 embodiment runs on real OpenUSD, not mini-USD facade. Tag
`v3.4.0-path-c` is the prior-art baseline for any future P1
amendment work.

When IP counsel is engaged on the CIP, point at this tag.

## Methodology note for tomorrow-you

The harness pattern (MoE roles + 8 Universal Commandments +
binary phase gates + halt-and-recover) carried Step 3 from
kickoff to public release in one day across multiple sessions.
**Three halt-and-recover events** (two truncations of framework
messages + one B2 baseline gap), all caught structurally rather
than by manual review. Architecture *is* the methodology.

This is reusable for Steps 4, 5, 6 and beyond. **Don't reinvent
it next session — adapt this harness shape to the new context.**

The shape that worked:
- Mile 1: package authoring (`01_KICKOFF.md` …
  `04_DEEP_THINK_BRIEF.md` + `05_DECISIONS.md`)
- Mile 2: phase-by-phase execution with internal commits at
  every gate boundary, push only at session close
- Mile 3: close summary + final Crucible audit + tag prep
  (no actual tag/PR — those are human-driven)
- Per session: Architect → Forge → Crucible serially within
  each phase, with named handoff artifacts

## State at session close

- Working tree: **clean**
- Stashes: **none**
- Open uncommitted work: **none**
- Halt-and-recover events today: **3** (all recovered cleanly —
  two framework-message truncations resolved by Option-2 pattern,
  one B2 baseline gap resolved by `[dev]` extra in Phase A)
- Wall-clock total: ~7–8 hours across all of today's sessions

**End of day. Step 3 done. Tomorrow-you: review PR, merge,
move to Step 4 when fresh.**
