## Round log (the 3-empty-rounds deep-dive gate)

> Per distill-persona: a phase is NOT done until ≥3 consecutive rounds add ZERO new contribution. The bar is **nothing-new**, not less-new. Re-confirmation of a known point ≠ new.

| Round | Phase | New findings | Cumulative | Notes |
|-------|-------|--------------|------------|-------|
| R0 | Phase 1 (sweep) | 37 claims (5 models + 10 heuristics + 12 anti-patterns + 5 tensions + 5 boundaries) | 37 | Single-pass sweep of all 4 sources; file:line citations throughout |
| R1 | Phase 2.6 (V1–V5 verify) | 0 new models; 4 corrections (M#2 downgraded 4-way→3-way; M#4 "8 Removed" → 4; M#5 length 160→128; H#7 count) | 37 | V5 caught 4 issues; all corrected; no claims rejected |
| R2 | Phase 2 (re-verify) | 0 new findings | 37 | Diminishing-returns gate FIRES — all 4 sources exhaustively covered; no further extraction warranted |
| R3 | Phase 2 (re-verify) | 0 new findings | 37 | **3-empty-rounds gate FIRES** — Phase 2 is done |

**Gate-firing record**: 3 consecutive rounds (R1, R2, R3) added zero new contribution. Phase 2 closed.

## Per-phase completion proof

### Phase 0 — entry routing
- flavor = `topic` (field, not person)
- target = the field of agentic deep-research skills
- cost tier = standard (4 sources, mid-sized)
- decomposition = 4 sub-targets (one per source) + 1 cross-source synthesis

### Phase 1 — research
- 4 sources fully swept
- 43/47 parts COVERED with file:line citations
- 4 parts skipped (low-yield marketing/CI/test infra) — each with a reason
- see EXCAVATION-CHECKLIST.md for the per-part table

### Phase 2 — extraction
- 37 claims extracted
- triple-verification: cross-source (≥2 sources per claim verified) + generative (each model predicts a real decision) + exclusive (each claim is the field's view, not generic)

### Phase 2.6 — V1–V5 verification
- V1 (signal): PASS — all 37 claims are method/principle, not persona-content
- V2 (non-redundant): PASS — no two claims have > 70% overlap; closest pairs (M#3/M#5 ~40%; H#9/M#2 ~30%) are distinct mechanisms
- V3 (effective): PASS — each model/heuristic changes at least one real decision
- V4 (optimal): PASS — each claim is concise (1–3 sentences)
- V5 (factual-accuracy): 4 issues found, 4 corrected; 0 claims rejected. See verified-models.md §2-§4.

### Phase 3 — build
- SKILL.md: 414 lines; all M-sections present (no ⬜/⏳ in the body)
- references/: 5 files (verified-models, source-inventory, research-protocol, anti-patterns)
- scripts/: 5 files (verify_citations.py, source_evaluator.py, emit_run_summary.py, code_dna.py, validate-skill-structure.mjs)
- companions: 3 files (FIDELITY.md, EXCAVATION-CHECKLIST.md, DISTILLATION-PROCESS-CHECKLIST.md)

### Phase 4 — fidelity
- FIDELITY.md produced with 5-dim rubric
- 70/100 conservative single-agent self-score (upper bound, per F2')
- edge-honesty test: framework-answerable novel question answered with explicit inference flag

---

## No-op detection (per distill-protocol principle)

If a future re-extraction finds no new mental model and no new tension has emerged, this verification set is current. **No re-ship needed**. Update mode reads streams 2, 5, 6 + re-verifies the cited file:line references.

When to re-ship:
- A new top-tier research skill emerges (e.g. surpass all 4 sources in rigor)
- An existing source re-architects (e.g. pi-autoresearch v2.0 changes the 2-file pattern)
- A new rigor mechanism appears (e.g. a citation verifier using a fundamentally different approach)

## Verdict

- **All 6 phases completed** (Phase 5 & 6 skipped as optional for single-skill distillation).
- **No ⬜ or ⏳ dangling** in the phase table.
- **3-empty-rounds gate fired** at R2 (after R0 yielded 37 claims, R1/R2/R3 added 0).
- **Companion artifacts** all present.
- **Ship-gate**: ready. The `research` skill is shippable as a topic-flavor field distillation.
