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
- callBound returns bound function for standard intrinsic methods
- bound Array.prototype.slice extracts array slices without direct prototype invocation
- bound String.prototype.indexOf searches strings with substring and index parameters
- bound Object.prototype.hasOwnProperty checks property existence on null-prototype objects
- supports intrinsic names enclosed with percent signs
- supports allowMissing parameter returning undefined for nonexistent methods on valid intrinsics
- throws TypeError when requesting nonexistent method without allowMissing flag
