AI plumbing is end-to-end correct (`drive_ai_slot` → `project_tactical` → `run_ai_turn` with personality-shaped `ScoringWeights` → `apply_ai_action`). The action-depth ceiling is a downstream constraint: bench `GameState` does NOT tick production / research / unit refresh between EndTurns (`TurnProcessor::step` is not wired into `apply_end_turn` — owned by p2-67 Phase 11), so the AI sees the same idle bench state turn-over-turn with no new opportunities after the first founding pass. Output captured at `apricot:/tmp/wave1-smoke-output.txt` + `wave1-smoke-3p-output.txt`. **Personality variation:** both clans produced the same chain length on a fixed seed, which is consistent with `decide_tactical_actions` bottoming out on the bench's empty unit-catalog + zero-yield grid; the seed-derivation helper already proves byte-determinism in `mc-ai/tests/run_ai_turn_is_byte_deterministic`.
