Summary

Removing additionalProperties:false from the tamper-evident signature object weakens schema validation on a security-sensitive record.

Severity

medium

Blocking findings

1. schemas/aep/evidence-envelope.schema.json:52 Removal of "additionalProperties": false from the signature object weakens validation on a security-sensitive (tamper-evident) schema: arbitrary unexpected properties are now accepted inside signature objects. The two new fields (bundle, transparency_log_ref) are added explicitly, so dropping the strict-mode guard is unnecessary and reopens the contract. For an evidence/signature schema this is a guardrail regression, not a cosmetic change.

Summary

PR adds useful signature fields and a conformance pytest wrapper, but it removes additionalProperties:false from the security-sensitive signature schema, weakening structural validation on the tamper-evident envelope.

Severity

medium

Blocking findings

1. schemas/aep/evidence-envelope.schema.json:46 Removes additionalProperties:false from the signature object, dropping a structural guardrail on the security-sensitive tamper-evident signature envelope. The new bundle/transparency_log_ref fields could have been added while retaining strict validation, so the removal unjustifiably allows arbitrary or mistyped fields to silently pass schema validation on a security-critical record.
2. schemas/aep/evidence-envelope.schema.json:26 Drops the field-level description ("Optional tamper-evident signature over the record content") from the signature property; consider keeping the documentation for a security-sensitive field.

Summary

PR adds signature extension fields but removes additionalProperties:false from a security-sensitive signature schema, weakening validation on tamper-evidence records.

Severity

medium

Blocking findings

1. schemas/aep/evidence-envelope.schema.json:52 Removal of "additionalProperties": false from the signature object drops strict validation on a security-sensitive (cryptographic signature) schema, allowing arbitrary extra fields in signature records. The new bundle/transparency_log_ref fields could have been added while preserving additionalProperties:false; dropping it removes a guardrail without justification.
2. schemas/aep/evidence-envelope.schema.json:45 The new "bundle" field is declared as type:object with no defined properties and no additionalProperties:false, leaving certificate/key material unconstrained. Consider defining its structure or restricting additional properties.

Summary

Schema loosening and resource-path fallback are intentional and covered by new tests; no blockers found.

Severity

low

Blocking findings

1. schemas/aep/evidence-envelope.schema.json:37 Removal of additionalProperties: false from the signature object loosens validation on security-sensitive (tamper-evident) evidence records; unknown signature fields are no longer rejected. Appears intentional since the new test asserts shape parity with aep-record, but confirm issue Fix #99: Create shared evidence-envelope schema with signature/version fields #110 actually calls for dropping the guardrail rather than just adding fields.
2. schemas/aep/evidence-envelope.schema.json:35 New bundle property is defined as a bare {"type": "object"} with no properties/required, providing no structural guarantees for a field that in a transparency-log/signature context likely carries cert or entry data.
3. src/wasmagent_protocol/__init__.py:32 Broad except (ModuleNotFoundError, TypeError, FileNotFoundError) in _read (and mirrored at line 85 in schema_path) falls back to a hardcoded parent.parent.parent/schemas path; catching TypeError can mask unrelated bugs and couples runtime behavior to the source-tree layout rather than the installed package.
