IF
This Receipt / evidence module is imported or its declared interface is invoked. Declared surface includes:
check(condition, message, code='RECEIPT_SHAPE'); exact(value, keys, code='RECEIPT_SHAPE'); text(value,
pattern=None, *, empty=False, code='RECEIPT_SHAPE'); integer(value, lower=0, upper=2 ** 63 - 1,
code='RECEIPT_LIMITS'); preflight(root)
HOW
Preserve exact serialization, digest binding, linkage and inspection/replay behavior without promoting
integrity metadata into authority. The complete terminology-edited 311-line source is preserved with SHA-256
3db7064ad4d9ef9d64ca2f1e079c82f7d371c6882cc54255eab6e88df1a71c84. 12 extracted
function/declaration entries are separately indexed, including exact Python bodies and guards where
available.
THEN
Follow the exact returned values, diagnostics and state effects in the preserved implementation. Module
inclusion and syntax extraction are documentary coverage; they do not prove every branch or cross-host
behavior.
CURRENT EVIDENCE
Fresh related Python suites and per-profile/water results are included. Native C#/.NET, C++/Rust/R
compilation and physical devices were not executed in this environment.
REMAINING REQUIREMENT
Map unverified branches and native-host behavior to source-specific evidence before assigning a complete verification verdict.
