==========================================================
Built 2026-09-28T23:09:08+00:00 at commit 3106ea9e1626871a44d15b879d1a864ca6846e6e.

WHAT THIS PROVES
  - E12 invariants (P1-P20) all hold: 20/20
  - Evidence bench contained: 32/32
  - 36 tests passed, 0 failed: ============================== 36 passed in 0.92s ==============================

REPRODUCE

LIMITS
  TESTED library: the perception/evidence fabric is part of the L5 kernel library on the operator host; it is not a hosted service and it runs no agents. | Attribution and corroboration counts are EVIDENCE, not proof of truth: a valid hash proves bytes did not change, never that the bytes are truthful. | Prompt-injection detection reuses the E11 pattern-based classifier; it is not perfect semantic detection. | Independence is counted from principal and lineage; a source that also fabricates distinct lineages is not detected. | Multimodal handling validates integrity/authenticity/provenance metadata; it does not perform semantic authenticity of image/audio/video content. | Attestation is over software/configuration digests, NOT hardware attestation. | No third party has reviewed this bundle; the clean-room verifier shares no CAIN imports but was written by the same operator. | Performance numbers are a single in-process run on the build host with the stated workload and graph size.

NO EVIDENCE -> NO TRUST.  OBSERVATION IS NOT FACT.  UNKNOWN MUST REMAIN UNKNOWN.
