Final verification pass complete — everything independently re-verified green. Report: **Phase 108 — History wire check (final verification pass; verdict: NO BUG, tests-only per D13)** - Verified all 3 tasks complete in `.agents/phases/complete/108_history_wire_check/`; re-ran every pin and gate myself - Layer 1 (unit): 2 owner-shape pins in `tests/unit/test_history.py` (2-turn keep-whole + A4 thinking mapping) — pass - Layer 2 (integration): `test_endpoint_two_turn_history_reaches_the_llm` — captured LLM request = `[system, user Q1, assistant R1, user Q2]`, `history_msgs=2` — pass - Layer 3 (E2E): `tests/e2e/test_history_wire_check.py` — owner's verbatim 3-message scenario, echo byte-exact (T2: `2 prior messages`+R1 tail; T3: `4 prior messages`+R2 tail) — pass - `VERDICT.md` present in phase dir: layer outcomes + "no bug — model behavior/user error" + pin names **Gates (exact results)** - `uv run pytest --cov=app --cov-report=term-missing` → 2305 passed, TOTAL **99%** (>90%) - `uv run pytest tests/e2e/test_history_wire_check.py -v --no-cov` → 2 passed (isolation, DB up) - `uv run pytest tests/e2e/test_llm_history.py -v --no-cov` (phase-74 regression) → 3 passed - `uv run ruff check .` → clean; `uv run pyright` → 0 errors **Completion criteria:** all six met — no defects found; diff scoped to `tests/**`, `VERDICT.md`, `.agents/phases/**`, `.agents/reports/**` (no `app/`/`frontend/` changes, consistent with no-bug verdict). Per executor rules, no git commit made — left for the harness. **Next pending phase:** `109_turn_progress_loader`
