fix(release): prevent stable PATH shadowing

[kattsushi]

Closes #255

Type

• Bug fix
• New feature
• Documentation only
• Code refactoring
• Maintenance/tooling
• Breaking change

Summary

Prevent protected stable PREPARE/FINALIZE record loops from shadowing the shell's executable PATH. Rename manifest fields to MANIFEST_PATH and preserve explicit, non-secret diagnostics for execution/parse versus identity failures.

Root cause

The workflow used:

while IFS='|' read -r NAME PATH OLD NEW

That replaced executable lookup with a manifest path. Consequently:

• run 33254079961 reported jq: command not found;
• run 33260806862 reported unauthorized source @effectify/hatchet because node could not be resolved and the fallback masked it.

Both runs stopped before Nx versioning and created no release branch or stable artifact.

Changes

• Rename every PREPARE/FINALIZE manifest field from PATH to MANIFEST_PATH.
• Keep manifest execution/JSON failures distinct from exact identity mismatches.
• Add phase-scoped contracts rejecting reserved PATH shadowing.
• Require every Node manifest command to consume MANIFEST_PATH.
• Add independent PREPARE-only and FINALIZE-only mutations.
• Preserve all versions, matrix, exact-SHA gates, path allowlists, reconciliation order, and publication behavior.

Verification

• Release-policy contracts: 19/19 passed.
• Ruby Psych parsed the workflow.
• Nx affected test/typecheck/lint/build passed.
• Repository format and git diff --check passed.
• Exactly two files changed: +26/−5.

Safety

• No Nx release lifecycle command ran locally.
• No workflow dispatch, release branch, protected ref, tag, GitHub Release, npm version, or dist-tag was created or changed.
• This PR does not authorize retrying stable PREPARE; retry remains a separate exact-SHA decision after merge verification.

Summary by CodeRabbit

• Bug Fixes

  • Improved stable release validation by clearly distinguishing manifest parsing or execution failures from identity mismatches.
  • Release processing now exits safely when package manifest data cannot be parsed.
  • Prevented path-variable conflicts that could cause incorrect manifest handling.

• Tests

  • Added checks to verify release validation rejects malformed manifest commands and reserved path-variable usage.

📝 Walkthrough

Walkthrough

The stable release workflow now preserves PATH, uses MANIFEST_PATH, handles manifest parse failures, and reports distinct failure types. Contract tests enforce these rules and cover mutations that reintroduce PATH shadowing or incorrect manifest arguments.

Changes

Stable manifest safety

Layer / File(s)	Summary
Workflow manifest checks .github/workflows/release-stable.yml	PREPARE and FINALIZE use MANIFEST_PATH, catch JSON.parse failures, and emit separate execution or parse and identity mismatch diagnostics.
Manifest policy contracts scripts/release-policy-contract.test.mjs	Contracts enforce the manifest command shape, reject PATH shadowing, require the new diagnostics, and test both mutation cases.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 2b41f

The release workflow now prevents manifest data from replacing the executable PATH, restoring command resolution in stable releases. Identity-mismatch failures still lack explicit actual-versus-expected package details, so the PR is mergeable with owner awareness and a follow-up to improve diagnostics and their contract tests.

Poem

A rabbit checks each manifest line
MANIFEST_PATH keeps the trail in time
Parse errors now speak clear and true
Identity checks know what to do
No shadowed PATH will hop anew

Full details: Linked Issues check

Explanation

The changes address the linked issue by replacing PATH with MANIFEST_PATH in stable PREPARE and FINALIZE manifest reads, preserving executable lookup, separating manifest execution or parse failures from identity mismatches, and adding contracts for reserved-variable shadowing and incorrect manifest usage. The summary also reports preservation of the existing release behavior and passing validation checks.

Full details: Out of Scope Changes check

Explanation

The two changed files are directly related to the linked issue. The workflow implements the PATH-shadowing and diagnostic fix, and the contract test adds coverage for the required behavior. No unrelated release, version, matrix, or publication changes are reported.
