+Themes: contract consistency (slots, effects, errors raised vs declared); agent / evaluator truth isolation (unknown samples); idempotent request
+ids; two instances isolated; step-partition independence (noise included); rejected calls leave the state unchanged; every output validated
+against its schema and every success changes only declared slots; pump-down within 12 h (calibrated), power failure with the isolation valve;
+magnet mass range (1-76 amu at 3 kV); continuous-flow CO2 against reference pulses (17O correction, internal precision <= 0.06 permil),
+normalisation with reference materials recovering an unknown; dual inlet internal precision (<= 0.010 / 0.016 permil 2 sigma at 100 bar uL);
+H2 with the H3+ factor (<= 8 ppm/nA); N2; ratio linearity; non-selected inlet vented; resistor switching and saturation; faults (helium, filament,
+vacuum leak, magnet drift, empty reference gas); ledgers (sample, reference and dual-inlet moles; helium) close exactly."""
