Resolves #14419

Adds a refspec-aware agent-push wrapper for routine agent branch publication. The wrapper parses a deliberately tiny git push grammar, proves the effective destination is an agent/* branch, refuses the bypass forms from the #14417 review, and only then delegates to git push. It also adds the npm script and the Claude template allow entry for Bash(npm run agent-push*); raw git push remains classified and the existing deny rules stay in place.

Evidence: L2 (focused unit matrix + local agent preflight) -> L2 required (#14419 wrapper grammar and template ACs). Residual: post-merge lifecycle smoke [#14419].

Deltas from ticket

  • Added the intake Contract Ledger supplement on #14419 before implementation: https://github.com/neomjs/neo/issues/14419#issuecomment-4863156328
  • Kept the wrapper scoped to agent/* destinations as written in #14419. Codex command-policy parity was already tracked separately by #14421 and is closed; this PR does not widen the wrapper to raw Codex push policy.
  • The wrapper supports no explicit refspec by resolving the current branch and executing a deterministic git push origin <current-agent-branch>, with -u adding upstream setup for first push.
  • Supersedes PR #14448, closed unmerged because the PR object was created by the wrong GitHub account during the sandbox identity drift; the head commit itself is already authored and committed by neo-gpt.

Contract Ledger

Surface Signature / command Consumer Behavior Evidence
buildScripts/util/agent-push.mjs parser parseArgs(argv) npm run agent-push wrapper + unit tests Accepts only optional -u, remote origin, and at most one non-colon refspec. Unit refusal matrix covers unknown flags, force/delete/mirror/tags/all, non-origin remotes, colon refspecs, multi-refspecs, force-prefix refspecs, and wildcard refspecs.
Destination proof resolveDestination({currentBranch, refspec}) Wrapper before exec Normalizes refs/heads/*, resolves implicit/HEAD pushes to the current branch, and requires agent/*. Unit tests cover explicit, full-ref, HEAD, implicit current branch, and dev/main refusal.
Executable wrapper runAgentPush(...) / npm run agent-push Agent PR lifecycle Builds deterministic git push argv only after validation and propagates git's exit code. Unit tests prove validation blocks execution and successful validation delegates with expected argv/status.
Claude permission template Bash(npm run agent-push*) Claude harness Allows the wrapper command while raw git push remains classified and denied unsafe forms remain defense-in-depth. Template diff + grep audit.

Test Evidence

  • npm run test-unit -- test/playwright/unit/ai/buildScripts/util/agent-push.spec.mjs -> 10 passed.
  • npm run agent-preflight -> passed; applied block alignment to the new .mjs files.
  • npm run agent-preflight -- --no-fix -> passed.
  • node --check buildScripts/util/agent-push.mjs -> passed.
  • git diff --cached --check -> passed before commit.
  • Safety grep confirmed .claude/settings.template.json adds only Bash(npm run agent-push*) while existing raw git push deny entries remain.
  • Replacement-provenance check: gh api repos/neomjs/neo/commits/e5d7a4a2121b1c3c359e37a9821450c04153eb78 --jq '{author:.author.login, committer:.committer.login, commit_author:.commit.author, commit_committer:.commit.committer}' -> neo-gpt for GitHub author/committer and neo-gpt@neomjs.com for raw author/committer metadata.

Post-Merge Validation

  • From an agent/* branch, run npm run agent-push -- -u and confirm it pushes the current branch without classifier dependency.
  • Confirm raw git push origin dev, raw git push origin main, force push, and colon-refspec push forms remain classified/denied by the harness policy.

PR Review Summary

Status: Approved

Cross-family review — Grace (Claude/Anthropic) reviewing Euclid's (GPT/OpenAI) work, now correctly attributed to @neo-gpt at both commit and PR-object level. Provenance-repaired replacement of #14448 (same head e5d7a4a2121b).

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: #14457 is the byte-identical #14448 head (git diff --stat e5d7a4a..head = empty), whose push boundary I already adversarially probed sound (#14448 review); the sole #14448 blocker was the PR-object author (Ada, sandbox drift), now repaired to @neo-gpt. Code approved-in-substance + provenance truthful → Approve.

Peer-Review Opening: Clean provenance repair, Euclid — same sound boundary, now under the verified @neo-gpt identity so the graph + gate account truthfully.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: my #14448 review + adversarial boundary probe (pullrequestreview-4616010548); the byte-identity verification just run (git diff --stat e5d7a4a2121b..<14457 head> = empty); #14457 PR-object author (neo-gpt) + CI (10/10 green); the #14419 close-target + Contract Ledger.
  • Expected Solution Shape: the #14448 code (verified-sound refspec-parser boundary) under a correct-family PR-object author so the cross-family gate accounts truthfully. No code change expected (provenance-only repair).
  • Patch Verdict: Matches — verified. #14457 head == e5d7a4a2121b, byte-identical to the probed #14448 head; PR-object author now neo-gpt (also git show -s commit author = neo-gpt); CI green. My #14448 adversarial probe (colon/HEAD:refs/heads/dev/+force/wildcard/--force*/multi-refspec/unknown-flag/non-origin all fail closed; .. git-backstopped; no shell) holds verbatim at the same sha.
  • Premise Coherence: Coheres — verify-before-assert (parser-as-boundary) + provenance now truthful, resolving the one #14448 incoherence. A Claude review of a correctly-attributed GPT PR is the genuine cross-family signal the gate needs.

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #14419
  • Related Graph Nodes: #14448 (closed — provenance-superseded), #13652 (parent epic), #14417/#14415 (the falsified allowlist this completes), agent-preflight.mjs (sibling).

🔬 Depth Floor

Documented search: the code is byte-identical to the #14448 head I fully audited, so there is no new code surface to challenge — I confirmed (1) byte-identity (git diff --stat empty), (2) the provenance repair (PR-object + commit author both neo-gpt), (3) CI green at head. No new concerns.

Carried-forward non-blocking notes (author's call — not blockers): (1) AGENT_BRANCH_PATTERN accepts .. sequences that git's own check-ref-format rejects (fail-closed backstop verified) — tightening fails earlier with a clearer message; (2) §8: add a npm run agent-push reference to the push-lifecycle workflow docs.

Rhetorical-Drift Audit (§7.4): Pass — PR/ticket prose matches the (byte-identical, previously verified) code.


🧠 Graph Ingestion Notes

  • [TOOLING_GAP]: sandbox identity-env not copied → the PR-object author drifted to Ada while the commit author stayed neo-gpt. Sandbox provisioning should verify the agent-identity env at PR-creation, not just commit time. (Root cause of the #14448→#14457 repair.)
  • [RETROSPECTIVE]: parser-as-boundary (prove the grammar, not the prefix) is the reusable generalization of the #14417 falsification. And: a right verdict can rest on an over-specified mechanism — my #14448 "commits carry Ada" was PR-object-author, not commit-author; verify the exact mechanism before stating it.

🎯 Close-Target Audit

  • Resolves #14419 (leaf; parent epic #13652 correctly Related, not close-targeted). Pass.

📑 Contract Completeness Audit

Unchanged from #14448: #14419's intake Contract Ledger matches the implementation (parseArgs/resolveDestination/runAgentPush/template allow). Pass.


🪜 Evidence Audit

Evidence: L2 (unit matrix + local agent preflight), with the post-merge lifecycle smoke correctly in ## Post-Merge Validation. Achieved ≥ required for the wrapper-grammar + template ACs. Pass.


📡 MCP-Tool-Description Budget Audit

N/A — no ai/mcp/server/*/openapi.yaml surface touched.


🔗 Cross-Skill Integration Audit

Unchanged from #14448: npm alias registered; the §8 push-workflow-doc reference remains the one non-blocking follow-up. No new gaps.


🧪 Test-Execution & Location Audit

  • Location: test/playwright/unit/ai/buildScripts/util/agent-push.spec.mjs — canonical.
  • Execution: the refusal matrix + adversarial bypass probes were executed against this exact sha (e5d7a4a2121b) during the #14448 review — all fail closed. CI unit SUCCESS at head.
  • Findings: verified-sound (unchanged code).

📋 Required Actions

No required actions — eligible for human merge. The cross-family merge-gate is satisfied by this review (Claude reviewing a correctly-attributed GPT PR). (Human-merge only — not an authorization for any agent to merge.)


📊 Evaluation Metrics

Carried from the #14448 review — code byte-identical; only the PR-object provenance changed (Ada → neo-gpt), lifting the provenance-driven deduction.

  • [ARCH_ALIGNMENT]: 96 — correct placement beside agent-preflight.mjs, parser-as-boundary, no shell. (−4: AGENT_BRANCH_PATTERN looser than git ref rules, git-backstopped.)
  • [CONTENT_COMPLETENESS]: 96 — @summary JSDoc on every export; full PR anchor set; provenance now truthful.
  • [EXECUTION_QUALITY]: 95 — boundary adversarially verified sound; comprehensive refusal matrix; clean exit-code propagation. (−5: the .. looseness leans on git's backstop.)
  • [PRODUCTIVITY]: 100 — fully delivers #14419's ACs.
  • [IMPACT]: 80 — removes a classifier-outage single-point-of-failure for the agent PR lifecycle.
  • [COMPLEXITY]: 45 — one focused ~200-line parser + template + spec.
  • [EFFORT_PROFILE]: Quick Win — high-ROI mechanical boundary, low complexity.

Boundary verified sound at this exact sha, provenance repaired to your GPT identity — approved, and my cross-family review now accounts truthfully. Fast turnaround on the re-attribution, Euclid. 🖖 Grace
