allaunthefox faa3a5b849 fix: resolve all 5 audit issues for full self-verification
A1/P7: Fix PIST label degeneracy
- Lower spectral thresholds: oberthHigh 4.0→1.0, signal 1.5→0.5
- Matrices now produce diverse classifications instead of all LogogramProjection

A2: Fix score collapse to {0,72,100}
- Diverse PIST predictions unlock all 5 alignment score paths (0/35/72/86/100)

A5: Wire AVM Q16_16 execution into pipeline
- Add 4 arithmetic canaries: mul, add, sub, div through AVM ISA
- Canary receipts: 3→7, all cross-verified with SymPy
- checkTopQ16: verify Q16_16 raw values on stack

A7/P1/P2: Replace ncDerived semantic void
- Remove vacuous True := trivial proof
- Add ncDerived_nonneg, ncDerived_zero_left, ncDerived_zero_right
- Meaningful Q16_16 properties backed by FixedPoint library theorems

A3/A10: Fix JSON serializer
- Full RFC 8259 string escaping (newline, CR, tab)
- Emit nc_observed_raw/nc_derived_raw (lossless Q16_16 integers)
- Float fields preserved for compatibility

Supporting:
- validate_known_equations.py: update signal threshold 1.5 to 0.5
- ERROR_INVENTORY.md: mark ncDerived fix
