Fresh governance runs exposed scripts/proven/verify-ledger.py and scripts/recon/compare.py as violations of the estate language policy. Replace them with a standalone, locked Rust dev-tool workspace and shell entrypoints, updating all active callers and the workflow's inline aggregate check. No language-policy exception or scanner suppression is added.

Retain the ledger selectors, bucket ordering, proof-file constraints, declared-absence conflict checks, remainder ratchet and JSON report contract. Test identities include the binary as well as the name so equal names cannot collapse across binaries. Reject empty inventories and stale claims without overwriting a successful artifact. Recon keeps category-debt comparison and explicit advisory mode; missing/invalid reports remain unavailable and do not produce a clean baseline proposal. Preserve failures from Cargo test enumeration instead of manufacturing an empty successful list.

Validation: six Rust library controls and three native Windows CLI integration tests pass, including the current repository ledger's selectors/taxonomy. All-targets Clippy with warnings denied passes. The existing CI-integrity job runs those contracts plus a Linux fault-injection test for failed/empty inventory enumeration. Hosted execution of the full suite, producer/aggregate interoperability and recon is pending, so this is a draft.

Details and the explicit OPEN/not-run Creusot/Pearlite and Verus plan are in docs/native-ci-helper-migration.adoc. This removes the governance blocker exposed while addressing hyperpolymath/echo-types#362; it does not claim formal proof or independent human approval.

Summary

Summary by CodeRabbit

  • Bug Fixes
    • Test inventory generation now stops on enumeration failures and rejects empty inventories, preventing incomplete results from being reported as valid.
    • Ledger and scan-report validation now provides clearer outcomes for missing or invalid reports and detected regressions.
  • Documentation
    • Updated CI guidance to reflect current validation commands and migration details.
  • Chores
    • Added automated checks for CI helper behaviour and Rust tooling, including strict linting.

The CI tooling replaces the Python ledger verifier and Recon comparator with Rust commands invoked through shell scripts. It also hardens test inventory generation and updates CI workflows, Justfile recipes, and documentation to use the new entrypoints.

Changes: Native CI helper migration

Layer / File(s) Summary
Ledger verification and report generation
tools/ci/Cargo.toml, tools/ci/src/lib.rs, tools/ci/src/bin/verify-ledger.rs, tools/ci/tests/cli.rs, scripts/proven/verify-ledger.py
The Rust package adds ledger and inventory validation, report generation, and a CLI. Tests cover validation rules and verify that failed claims do not overwrite an existing report. The Python verifier is removed.
Recon comparison
tools/ci/src/lib.rs, tools/ci/src/bin/recon-compare.rs, tools/ci/tests/cli.rs, scripts/recon/compare.py
The Rust command reads Assail and Pons reports, compares finding counts with the baseline, and reports regressions or unavailable reports. It can append a report to a summary file. CLI tests cover regression, clean comparison, and unavailable-report handling. The Python comparator is removed.
Inventory failure handling
scripts/proven/inventory.sh, scripts/ci/test-inventory-failure.sh
The inventory script preserves enumeration failures and rejects empty inventories before writing output. The new shell test checks both failure cases.
CI entrypoints and references
scripts/proven/verify-ledger.sh, scripts/recon/compare.sh, .github/workflows/*, Justfile, .gitignore, docs/CI-CD.adoc, docs/native-ci-helper-migration.adoc, proven/ledger.json
Shell scripts invoke the locked Rust binaries. Workflows and Justfile recipes use the scripts; the ledger and CI documentation identify the new ledger verifier. CI runs Rust tests and Clippy, and uses jq for aggregate report checks.

The migration appears functionally sound from the supplied context. One function exceeds the project's complexity gate and should be split before merge to keep quality checks green.

Comment thread tools/ci/src/bin/recon-compare.rs Resolved
hyperpolymath added a commit that referenced this pull request Nov 7, 2026
The committed recon baseline includes an `_comment` array. The native
comparator previously tried to deserialize that metadata as scanner
counts, so scheduled recon and `just recon` failed before reading
reports. Read a typed assail/pons envelope, preserve strict count
validation, and exercise the actual committed baseline through the CLI.

Split ledger derivation into inventory, taxonomy, assignment, grading
and absence checks without changing its report or exit-code contracts.
This addresses the follow-up review on #270 and contributes to
hyperpolymath/echo-types#362.

Validation: Windows native helper tests (10 test executions) and
all-target Clippy with warnings denied passed. The CLI checks successful
comparison, regression exit 1, malformed input/unavailable report exit
2, metadata tolerance and withholding a baseline proposal on missing
reports. Hosted checks and final review remain required before merge.
Creusot/Pearlite and Verus remain OPEN/not run as documented; these are
regression tests, not formal proof.
