Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures.
Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments.

Contract
- assert numeric string above Integer.MAX_VALUE deserializes to AtomicLong without 32-bit truncation
- assert floating-point token above Integer.MAX_VALUE preserves the 64-bit integral value under ACCEPT_FLOAT_AS_INT
- assert negative numeric string below Integer.MIN_VALUE preserves negative 64-bit value
- assert large integral token near Long.MAX_VALUE deserializes to AtomicLong and bean property
- assert disabling ACCEPT_FLOAT_AS_INT rejects floating-point input
- assert configuring integer String coercion to Fail rejects quoted numeric string
