Phase 65: Space & EW Sub-Engine Activation

Status: Complete Tests: 43 new (5 test files) Source files modified: 6 (zero new source files)

Overview

Wires five dormant space engines and two dormant EW engines that were fully implemented internally and instantiated on SimulationContext but whose outputs were never consumed by downstream systems. Fixes two latent bugs in _fuse_sigint() that have kept SIGINT fusion dead since Phase 52d. All behavioral changes gated by enable_space_effects=False (default). This is Block 7, Phase 8 of 10.

Bugs Fixed

  1. engine.py _fuse_sigint() line 807: getattr(ew, "sigint_engine", None) searched JammingEngine for sigint_engine. Fixed to getattr(ctx, "sigint_engine", None) — sigint_engine is a top-level SimulationContext field.

  2. engine.py _fuse_sigint() line 804: getattr(ctx, "intel_fusion_engine", None) — attribute never existed on ctx. Fixed to access via fog_of_war.intel_fusion property. Both bugs meant SIGINT fusion was dead code since Phase 52d.

  3. ISR reports discarded: SpaceISREngine.update() called generate_isr_reports() but discarded the return value. Fixed with _recent_reports buffer and get_recent_reports() method.

Implementation

Step 0: CalibrationSchema + Infrastructure (9 tests)

  • CalibrationSchema.enable_space_effects: bool = False — gates ISR fusion, early warning, SIGINT intercepts
  • SpaceISREngine._recent_reports buffer + get_recent_reports(*, clear=True) method
  • target_position and timestamp fields added to ISR report dicts
  • ISR state persistence updated (get_state/set_state include recent_reports)
  • FogOfWarManager.intel_fusion property — exposes _intel_fusion for SIGINT/ISR track injection

65a: Space ISR & Early Warning (10 tests)

  • Bug fix 1: sigint_engine accessed from ctx, not ew_engine
  • Bug fix 2: fusion engine accessed via fog_of_war.intel_fusion, not nonexistent ctx.intel_fusion_engine
  • _fuse_sigint() gated by enable_space_effects
  • ISR report dict handling (.get() for dicts, getattr for objects)
  • Early warning: MissileLaunchEvent subscription in _register_event_handlers()
  • _handle_missile_launch() handler: finds launcher unit, calls check_launch_detection() for opposing sides

65b: ASAT & SIGINT (10 tests)

  • SIGINT collector loading from ew_config YAML in _create_ew_engines()
  • _run_sigint_intercepts(): iterates registered collectors, synthesizes Emitter from active JammerInstance, calls attempt_intercept()
  • Collector positions updated from unit positions each tick
  • _attempt_asat_engagements(): structural placeholder (no ASAT weapon YAML exists)
  • Call sites wired: _run_sigint_intercepts() after _update_ew(), before _fuse_sigint()

65c: ECCM Integration (8 tests)

  • ECCM suite loading from ew_config YAML in _create_ew_engines()
  • battle.py: after snr_penalty_db computed, query eccm_engine.get_suite_for_unit(), subtract compute_jam_reduction() before applying ew_factor
  • Self-gating: no registered suites = 0 dB reduction (no CalibrationSchema flag needed)
  • All 4 techniques tested: frequency hopping, spread spectrum, sidelobe blanking, adaptive nulling

Structural Verification (6 tests)

Source-level string assertions verifying all wiring is present and bug fixes hold.

Deferrals

ID Item Reason
D1 SIGINT traffic analysis (analyze_traffic()) Requires intercept history accumulation
D2 BMD interceptor cueing from early warning Requires BMD units + intercept routing
D3 AI-driven ASAT targeting Requires commander decision extension
D4 ASAT weapon YAML data No ASAT weapon definitions — can't exercise ASAT
D5 Adaptive nulling direction calculation Requires jammer bearing geometry
D6 ISR-to-FOW direct injection ISR→fusion only; full FOW contact injection separate
D7 Auto-registration of SIGINT collectors from sensors Complex synthesis from sensor defs
D8 EW decoy deployment in battle loop deploy_decoys() never called from engagement

Lessons Learned

  • Dead code since Phase 52d: Both _fuse_sigint() bugs meant the entire SIGINT fusion pipeline was unreachable. Only discovered during systematic namespace tracing.
  • Dict vs object reports: ISR reports changed from objects to dicts; _fuse_sigint() needed dual handling (isinstance(sr, dict) check) for forward compatibility.
  • JammerInstance lacks side: Synthesizing Emitter from JammerInstance requires defensive defaults since jammer has no side attribution.
  • Self-gating pattern: ECCM needs no CalibrationSchema flag — no registered suites means get_suite_for_unit() returns None, zero reduction applied.

Postmortem

  • Scope: On target — 43 tests vs ~40 planned
  • Quality: High — 2 latent bugs fixed, zero regressions, all opt-in gated
  • Integration: Fully wired for ECCM + SIGINT + early warning; ASAT structural only
  • Deferrals: 8 items (D1-D8), all reasonable — no ASAT data, traffic analysis is secondary
  • Performance: No impact — all new code paths gated by enable_space_effects=False
