Normalize those calls before Tier 3 checks so collectors do not treat missing execution evidence as a successful inner call. Changes: - Add one dependency-free Codex tool-call normalizer for the package evaluator and copied Harbor verifier. - Keep unsupported wrappers atomic with an explicit unsupported_native_codex_exec_wrapper status, and assign wrapper observations only to uniquely rendered inner calls. - Add stable inner evidence_id values for deduplication, report lookup, Rich rendering, and suggestion grounding. - Reject unsupported execution evidence across activation, script, workflow, negative-case, routing, efficiency, recovery, and security checks while preserving generic non-Codex exec calls. - Expand regression coverage and record the release impact in the changelog. Impact: Tier 3 now distinguishes observed inner calls from unobserved, ambiguous, and unsupported native Codex wrappers. Reports and suggestions reference the correct normalized evidence, and the standalone verifier uses the same parser as package evaluations. Validation: - Focused tests: 78 passed. - Tier 3 suite: 664 passed. - Full suite: 5222 passed, 17 skipped, 4 deselected. - Lint: all checks passed. - Build: created the source archive and wheel, including codex_tool_call_normalizer.py. - git diff --check: passed. Notes: Generic exec calls without a string arguments.input remain unchanged for non-Codex compatibility. This repository has no PR CI configured.

preserve generic exec calls Context: The normalizer treated every `exec` call with string `arguments.input` as native Codex evidence. ATIF permits generic input payloads, and the normalizer does not receive trajectory-level agent provenance. Changes: - Preserve unparsable `exec` input atomically unless the source contains a first-line Codex pragma or a `tools` wrapper reference. - Reuse the pragma pattern in parsing and signature detection. - Add the generic ATIF input regression to the shared and packaged verifier extractors. Impact: Generic `exec` input remains scorable as its original atomic call. Malformed or unsupported inputs with a native Codex signature continue to fail closed. Validation: - Exact generic-input regression: 2 passed. - Full Codex normalization test module: 65 passed. - Narrow downstream Tier 3 consumer tests: 81 passed. - Ruff lint and format checks: passed. - `git diff --check`: passed. Notes: The full repository suite and a captured real Codex trajectory replay were not run locally.

Changes: - Match direct and quoted computed-property tool members only when followed by call syntax. - Preserve the existing escaped-parenthesis signature used by regex-literal wrapper evidence. - Extend the shared and packaged extractor regression matrix with sentence-ending and property-name prose.

Tier 3 evidence consumers now resolve one stable identity in evidence_id, json_pointer, then path order. Changes: - Cap wrapper input at 64 KiB, object nesting at 64 containers, parsed statements at 256, and inner tool calls at 128. - Strip caller-supplied _atif_* fields before normalization, centralize normalized traversal and observation ownership, and scan unsupported-wrapper observations for secrets. - Add a shared evidence-reference identity helper for report rendering, deduplication, Harbor prompts and lookup, and the standalone verifier. - Copy the normalizer and evidence helper with Harbor verifier tasks and add shared, standalone, packaging, parser-boundary, security, and reporting regressions. Impact: Forged normalization metadata cannot suppress destructive-command or secret-exposure findings. Oversized or unsupported wrappers fail closed without interpreting arbitrary JavaScript. Normalized, pointer-only, and path-only evidence references retain stable distinct identities across reports and remediation suggestions.
