Exposed by a new hotseat full-game driver (drives both player seats over the
multi-slot wire, no AI dependency) — a 31-turn 2-player game surfaced these.
- mc-player-api: the AI→PlayerAction converter (apply_ai_action + the suggest
sibling) emitted the bare tactical city index ("0") for QueueProduction, but
find_city_indices needs the projector wire id "{player}_{c_idx}" — so every
AI/suggested queue_production failed UnknownCity. This silently broke the
in-box AI's production-steering, not just the wire. Emit the wire id at all
three sites; thread slot into the suggest converter; add a regression test.
Result in the playthrough: roundtrip failures 58→1, city_building_completed 0→18.
- api-gdext: advance_round_phase/end_player_round_phase did not compile at HEAD —
godot-rust 0.2.4 Array::push needs &Dictionary (AsArg); Pcg64 builds via ::seed
not ::seed_from_u64; dropped a dead rng binding. The gdext crate could not be
rebuilt from source until this.
- mc-worldsim: pub use GamePhase/RoundPhase (api-gdext references them through
mc_worldsim; they were a private re-export → E0603).
- tooling: add hotseat_playthrough.py — applies each seat's suggested actions
and flags any offered action that fails to apply, with severity triage.
