The pre-flight circuit verifier reads branch currents via runNetlist ->
readAllCurrentVectors() (ngSpice_AllVecs enumeration). The production
Web-Worker ngspice WASM build does not surface voltage-source #branch
vectors through that enumeration for an .op plot, so branchCurrents came
back empty and every current rule (short-circuit, LED over-current) read
?? 0 -> no fault. The live solver avoided this by requesting each current
explicitly by name; the Node test build enumerates them, so the gap was
invisible to the suite. Net effect: a 9V battery wired straight to an LED
ran with no warning (reported on project 2840fd12).
- runNetlist: request every V_* source branch current explicitly by name
and merge with the enumeration, so source/LED currents are always present
regardless of the worker WASM's AllVecs behaviour.
- circuitVerifier: non-finite source/LED current -> blocking unstable-solve
fault ("could not solve a stable current - likely a short or a part with
no current limit, e.g. an LED with no series resistor").
- LED runtime (BasicParts): burn out on a non-finite current instead of
falling through to the digital fallback and glowing; raise burnout
threshold 20mA -> 100mA so high-power/RGB channels are not falsely
destroyed; clear the burnt latch on Reset (resetBoard bumps hexEpoch).
Tests: real-data repro, mocked non-finite verifier test, runtime
non-finite / high-power / latch-recovery tests.
