C1-A04 follow-up — Distinguish repair.push source role

[LogicDuke]

Purpose

Quarantined stacked validation repair for one CURRENT / P3 finding discovered during exact-current-head review of PR #40.

This PR is intentionally stacked directly on PR #40.

Required base:

repair/c1-push-source-binding

Required parent HEAD:

077933d3a3df574c8a40c8074e0c2d918445cced

It MUST NOT target PR #36, PR #35, PR #21, PR #14, or main.

Finding

CURRENT / P3 — PR40-CODEX-PUSH-SOURCE-MUTATION-TARGET-WORDING

PR #40 correctly binds both the effective repair.push source and destination identities to the authorized repair ref, but its TSDoc groups both under wording describing "the effective mutation target it will actually advance."

That collapses two distinct semantic roles:

• push source: consumed / validated input selecting what is sent;
• push destination: receiving / mutation target advanced by the push.

The executable behavior is not defective; this is a bounded contract-mirror semantic defect.

Source review:

• PR C1-A04 follow-up — Bind repair.push source to authorized ref #40 thread PRRT_kwDOTzqfcs6a9FR0
• comment PRRC_kwDOTzqfcs7kAFL9

Repair

The repair changes only:

src/domain/repair-job.ts

The TSDoc now distinguishes:

• commit effective HEAD as the mutation target advanced;
• push destination as the receiving / mutation target advanced;
• push source as the input consumed to select what is sent.

Both push identities remain required to be the authorized repair ref.

The existing protections remain intact:

• absent/deletion source rejected;
• redirected source rejected;
• alternate branch/tag/commit-ish source rejected;
• protected-parent denial preserved;
• force-push denial preserved;
• branch.delete denial preserved;
• ref-name identity remains distinct from commit-OID identity;
• consuming-boundary / TOCTOU rule preserved;
• permit/domain operand remains distinct from derived execution identities.

Scope

Changed file exactly:

• src/domain/repair-job.ts

TSDoc/comment-only.

Zero executable TypeScript behavior changes.

No runtime API, type, operation, permit operand, Git/filesystem/network/subprocess authority, Ready authority, or merge authority added.

Independent Validation

Result:

PASS

Validated parent:

077933d3a3df574c8a40c8074e0c2d918445cced

Validated commit:

6812607a81dda46e3cf5ca3c3105b9bfe7fa6322

Validated binary patch SHA-256:

4B75D1B0372B2C2F7D520DAEBB7DCA6362665B5836486BB189462519259ECCE4

Validated patch bytes:

1789

Independent validation proved:

• exact one-file scope;
• TSDoc/comment-only patch;
• push source modeled as consumed/validated input;
• push destination modeled as receiving/mutation target;
• both remain authority-bound to the authorized repair ref;
• consistency closure PASS;
• PS1–PS6 preserved;
• executable TypeScript identical: 2939 → 2939 tokens under the same TypeScript scanner, identical token-stream hash;
• git diff --check PASS;
• typecheck PASS;
• lint PASS;
• full test suite PASS: 882 tests / 15 files;
• build PASS;
• candidate fingerprint identical before and after independent validation;
• committed patch byte-identical to validated candidate.

Quarantine

Required lifecycle:

this DRAFT child
→ exact-head CI
→ independent GitHub reviews
→ classify every new finding
→ policy/evidence gate
→ Ready
→ POST-READY review/check observation
→ PASS: human CREATE A MERGE COMMIT upward into PR #40 branch
→ establish PR #40 NEW HEAD
→ fresh PR #40 parent audit

If Ready/post-Ready review finds a CURRENT defect:

RETURN THIS PR TO DRAFT.

Do not repair it directly.

Create another isolated child from the exact affected HEAD.

FAIL means reject/discard/quarantine this child.

PR #40 remains protected and untouched until successful human integration.

MERGE IS OPERATOR-ONLY.

No AI may merge this PR or enable auto-merge.

📝 Walkthrough

Walkthrough

The repair job documentation now distinguishes commit and push identity handling. Commits bind the effective HEAD referent. Pushes validate destination and source identities against the authorized repair ref and reject absent, redirected, or protected-parent identities.

Changes

Repair reference safety

Layer / File(s)	Summary
Effective identity safety rules src/domain/repair-job.ts	The canonical branch-reference requirements now define effective HEAD binding for commits and separate destination and source validation for pushes. Unsafe identities are refused.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: ⚪ Minimal · up to 68126

This PR only clarifies documentation for push source and destination roles without changing executable behavior; no actionable merge-blocking risk remains after normal checks and review.

Poem

I’m a rabbit guarding the ref,
HEAD stays bound, safe and correct.
Push source and destination align,
Protected parents cross no line.
Absent paths get turned away—
Clean repair rules hop today!
