+## Phase A completion log
+
+Closed in 11 commits across one session. Six primitives emit; the
+five-class calibration grid is the binding regression test for
+every subsequent phase.
+
+| Primitive | Confidence | Empirical anchor (2026-05-02 corpus) |
+|---|---|---|
+| `motor.input_modality` | 0.70 / 0.75 | YOU-sim 47.6% paste → ``pasted``; HUMAN <5% → ``typed`` |
+| `motor.paste_burst_rate` | 0.70 / 0.80 | LW-sim / CLAUDE-FF / CLAUDE-CL ≥50% → ``habitual`` |
+| `cognitive.inter_command_latency_class` | 0.40 / 0.80 | CLAUDE-FF 15.5s median → ``llm_heavyweight`` |
+| `cognitive.command_branch_diversity` | 0.80 / 1.00 | CLAUDE-CL ≈0.55-0.60 → ``adaptive_branching``; threshold 0.70 |
+| `cognitive.feedback_loop_engagement` | 0.75 / 1.00 | CLAUDE-FF flat r → ``fire_and_forget``; r > 0.30 → ``closed_loop`` |
+| `cognitive.inter_command_consistency` | 0.40 / 0.75 | LLM CV≈0.24 → ``metronomic``; HUMAN CV≈0.94 → ``variable`` |
+
+The hard gate (every Phase A primitive must fire per shard) is in
+``tests/profiler/behave_shell/test_calibration_grid.py`` and skips
+cleanly when ``BEHAVE_CALIBRATION_DIR`` is unset.
+
+Per-class **value** pinning (e.g. HUMAN must emit
+``inter_command_consistency=bimodal``) is intentionally NOT a hard
+gate at this milestone — v0.1 thresholds put real human sessions
+in ``variable``, and true bimodal detection (Hartigan dip /
+two-peak) is registry-flagged for v0.2. Tighter pinning lands as
+the corpus grows.
+
+**Worker unblocked:** ``BEHAVE-INTEGRATION.md`` Phase 4 can now wire
+the per-session producer against the Phase A engine; the Tier-A
+corpus continues to grow under Phases B-G without changing the
+worker's interface.
