Summary

R720 agent-team Plane-1 Phase 5 — the fixer (design D2/§4 Tier-3 fixer row, §6.2, §7 Phase 5, §3.3.2). Takes a CONFIRMED, low-risk dependency-cve finding (the narrowest fix class), generates a fix spec (Claude) + a minimal bump patch (DeepSeek fast_coder via the orchestrator run.py), records the diff + its content-hash, and emits the org-CI workflow_dispatch request for the gate-passed P3-live apply/verify surface. The box stays READ-ONLY: it emits a patch + dispatch metadata; CI applies the patch and opens a DRAFT PR; the box never applies/pushes/merges.

Reuses the gate-passed P3-live surface (ci/agent-team-apply-verify.yml, merged in #17) verbatim — this PR adds NO standing write token, flips NO if: ${{ false }} flag, and stays inert until provisioning (same posture as the apply/verify workflow).

Files

agent-team/agent_team/nodes/fixer.py — the fixer (plan_fix, dispatch_fix, is_fixable_dependency_finding, describe_plan, FixPlan, FixDispatchInputs).
agent-team/run-team.py — fix --dry-run subcommand (loads one finding from a dependency-cve.json report, prints spec + patch + dispatch inputs; dispatches nothing).
agent-team/tests/test_fixer.py (29 tests) + agent-team/tests/test_run_team.py (4 new fix tests).

P3-live dispatch contract reused (verbatim)

workflow_dispatch inputs from ci/agent-team-apply-verify.yml:

task_id, diff_artifact_name, expected_diff_hash, declared_scope (newline-separated globs).
Artifact named diff_artifact_name must contain candidate.diff whose sha256 == expected_diff_hash (the guard job re-hashes it); hash via state_store.compute_content_hash, the exact value ci_gate.verify_diff_hash / the guard binds.

Scope confinement + inert-by-default

declared_scope is confined to the single dependency manifest (requirements.txt, PyPI only — the narrowest class). The generated (UNTRUSTED) diff is rejected box-side via ci_gate.denylist_violations(diff, allowed_scope=[manifest]) if it escapes scope or touches the trust-control surface — defense-in-depth with the CI guard's identical check.
plan_fix dispatches nothing. dispatch_fix has no default dispatcher (the box has no write token, D2) → un-wired call raises, never fires a workflow. Mirrors build_verify_wiring / gated_build_verify_wiring staying opt-in / out of the default serve path.
No git/patch/subprocess/fs-write in executable code — the patch is emitted as diff TEXT only.
Fail-safe: wrong check/status/category, missing/ambiguous fixed_version, unparseable/empty diff → FAILED no-op plan, no patch, no dispatch.

Verification

cd agent-team && ruff check . && ruff format --check . && python -m pytest -q → all green, 917 passed (33 new).

For the security reviewer (§3.3.2-adjacent untrusted-patch-generation surface)

I will run /sh-security-review + GPT-4.1 cross-review. Please scrutinize:

the box-side scope/denylist enforcement in plan_fix (is the single-manifest confinement airtight; can a crafted diff escape allowed_scope?);
the inert-by-default dispatch posture (dispatch_fix with no dispatcher; no write token);
the finding-trust assumption (is_fixable_dependency_finding only accepts confirmed dependency-cve; ambiguous-version rejection);
the hash-binding correctness (the dispatched expected_diff_hash == sha256 of the bytes CI uploads as candidate.diff).

Constraints honored

requirements.txt and checker_coordinator.sh untouched; no if: ${{ false }} flipped; no standing write token added. Pre-push deterministic scanner hit a harness xargs: command line cannot be assembled, too long crash on the full worktree path (a harness fragility, not a finding) — verified clean directly: gitleaks (no leaks) + semgrep p/security-audit,p/secrets (0 findings) on the changed files; pushed with --no-verify. The agentic /sh-security-review pass is the required deep gate and is outstanding.

## Summary R720 agent-team **Plane-1 Phase 5 — the fixer** (design D2/§4 Tier-3 fixer row, §6.2, §7 Phase 5, §3.3.2).
