The service is the single owner of the simulation loop. Replaces
the trio of wireElectricalSolver + connectLegacySolverToMixedMode +
connectMixedModeSchedulerToStore once G* lands.
Architecture:
- Depends on PORTS only — SimulatorStorePort, ElectricalStorePort,
MixedModeSchedulerPort. Zero coupling to useSimulatorStore /
useElectricalStore / WASM. Easy to test with fakes (and that's
what circuit-simulation-service.test.ts does).
- Single tick(): build netlist → load → solve → extract → publish.
Coalesces concurrent triggers so rapid store changes collapse to
one trailing solve.
- Domain ElectricalSnapshot type covers nodeVoltages + branchCurrents
+ pinNetMap + timeWaveforms + analysisMode + warnings. Shape
matches what the 12 existing useElectricalStore consumers read.
NetlistBuilder extension: BuildNetlistResult now reports `nets`
(every non-ground SPICE net) and `voltageSources` (every V card the
builder emitted). The service uses these to construct the full
vectorsOfInterest list — every node voltage + every branch current
— so the solver returns the data the legacy consumers want.
Scheduler addition: `setExtraVectorsOfInterest(vectors)` lets the
orchestrator add to the per-pin set. Branch currents (i(v_*))
flow through this hook.
8 service tests cover initial solve, branch current extraction,
re-solve on store change, no-spurious-solve, coalescing, .tran
waveforms, warnings forwarding, error-tolerance.
Next: C1+C2 — extract ADC injection / waveform replay into a
solver-agnostic module that just subscribes to useElectricalStore.
