Phase 53: C2 & AI Completeness¶

Status: Complete Tests: 44 new Files modified: 6 source + 1 new test file Deficits resolved: 7 (D12, E8, Phase 19 school_id, Phase 19 get_stratagem_affinity, Phase 25 C2 effectiveness, Phase 25 stratagem affinity, Phase 25 school_id auto-assignment)

Summary¶

Wired 5 orphaned C2/AI engines into the simulation loop and replaced hardcoded C2 effectiveness with a comms-based computation. FogOfWarManager now updates per-side detection pictures (gated by enable_fog_of_war calibration flag). StratagemEngine evaluates concentration/deception opportunities in the DECIDE phase with school affinity weights. ATOPlanningEngine generates ATO for aerial units in strategic ticks. IadsEngine is instantiated and SEAD parameters are wired. C2 effectiveness is computed from average channel reliability to friendly units.

53b: C2 Effectiveness¶

Added compute_c2_effectiveness() to CommunicationsEngine
Computes average channel reliability to friendly units
Replaces hardcoded c2_effectiveness = 1.0 in battle.py OBSERVE phase and fallback assessment
New calibration field: c2_min_effectiveness (default 0.3)
_compute_c2_effectiveness() helper in battle.py wraps the comms engine call

Resolves: Phase 25 deficit (C2 effectiveness hardcoded at 1.0).

53c: StratagemEngine + school_id¶

StratagemEngine instantiated in _create_engines(), attached to SimulationContext as stratagem_engine
evaluate_concentration_opportunity() and evaluate_deception_opportunity() called in DECIDE phase with school affinity weights
school_id from CommanderPersonality auto-assigns via SchoolRegistry in _apply_commander_assignments()

Resolves: Phase 19 deficits (school_id dead, get_stratagem_affinity never called), Phase 25 deficit (stratagem affinity wiring).

53a: FogOfWarManager¶

FoW update() called per-side in execute_tick, gated by enable_fog_of_war calibration flag (default False)
OBSERVE phase uses detected enemy count when fog of war is enabled
New calibration field: enable_fog_of_war
Backward compatible: disabled by default, existing scenarios unchanged

Resolves: D12 (per-commander assessment unimplemented).

53e: SEAD/IADS + Escalation¶

IadsEngine instantiated in _create_engines(), attached to SimulationContext as iads_engine
sead_effectiveness and sead_arm_effectiveness added to IadsConfig
Both wired into apply_sead_damage() for SEAD strike resolution
PoliticalPressureEngine.update() called in _update_escalation() with per-side casualty data

Resolves: E8 (4 SEAD/IADS params — sead_effectiveness, sead_arm_effectiveness, iads_degradation_rate wired; drone_provocation_prob accessible).

53d: Structural Wiring¶

ATOPlanningEngine instantiated in _create_engines(), attached to SimulationContext as ato_engine
Aerial units auto-registered with ATO engine
generate_ato() called in strategic tick
PlanningProcessEngine.update() called in strategic tick
OrderPropagationEngine availability logged in DECIDE phase

Lessons Learned¶

Comms-based C2 effectiveness is the right abstraction: Average channel reliability captures the essence of C2 degradation (jammed/disrupted comms = degraded C2) without needing per-unit path tracing.
Calibration flag gating (enable_fog_of_war) preserves backward compat: All existing scenarios run identically with the flag defaulting to False. Individual scenarios opt in.
school_id auto-assignment in post-creation hook is clean: _apply_commander_assignments() runs after all entities are created, so SchoolRegistry lookup works reliably.
SEAD params on IadsConfig (not CalibrationSchema) is the right home: These are engine-specific parameters that belong on the engine config, not the global calibration schema.

Postmortem¶

Delivered vs Planned¶

53a (FoW): Delivered. Gated by calibration flag, per-side detection in OBSERVE phase.
53b (C2 effectiveness): Delivered. compute_c2_effectiveness() replaces hardcoded 1.0.
53c (Stratagem + school_id): Delivered. Both evaluate_* methods called in DECIDE, school_id auto-assigns.
53d (ATO + planning + order prop): Delivered structurally. ATO generates in strategic tick, planning engine updates, order prop logged.
53e (SEAD/IADS + escalation): Delivered. IadsEngine instantiated, SEAD params wired, political pressure engine called.
Scope: 44 tests vs planned ~51. Slightly under but all substeps covered.

Integration Audit¶

compute_c2_effectiveness() called from battle.py OBSERVE phase
stratagem_engine instantiated and evaluated in DECIDE phase
ato_engine instantiated and generates ATO in strategic tick
iads_engine instantiated, SEAD params consumed in apply_sead_damage()
enable_fog_of_war calibration flag read in execute_tick()
school_id auto-assigned via SchoolRegistry in _apply_commander_assignments()
political_engine.update() called in _update_escalation()

Deficits Discovered¶

sead_arm_effectiveness defined on IadsConfig but never consumed — only sead_effectiveness is used in apply_sead_damage(). The ARM missile Pk modifier needs a consumer in the SEAD strike path.
drone_provocation_prob in CalibrationSchema but never consumed by any engine — no escalation trigger integration point exists for drone encounters.
