/team fix — Fix Pipeline

> Called by team.md router when action is `fix`.

Role Selection Bias

| Layer | Preferred Roles | Count | |-------|----------------|-------| | L1 | technical-analyst, security-analyst | 2 | | L2 | (domain-dependent engineers) + qa-test-architect, performance-eng (if perf-related) | 2-4 | | L3 | domain-accuracy | 2 | | L4 | principal-architect | 1 |

Issue Detection

L1 agents identify issues from:

• Conversation context (user described bugs, review findings, error logs)
• `.planning/` review documents (if GSD active)
• Test failure output

Group issues by file ownership — no two L2 agents touch the same files.

Pipeline Customization

Layer 1: Diagnosis

L1 agents focus on:

• Root cause analysis for each reported issue
• File mapping — which files need changes
• Impact assessment — what else might break
• **Component triage.** When `.arch/index.json` exists and is CURRENT, name the component

each issue falls inside, from `.arch/INDEX.md`. This is a triage and communication aid: it groups related issues and tells a reviewer which boundary is under repair. It is not a constraint on which files the fix may touch — a legitimate fix routinely spans several components, and the index is at a coarser altitude than the change. Do not escalate a cross-component fix as a boundary violation.

• If a fix genuinely deletes or relocates a component's primary paths, note it so

`/team arch drift` can reconcile the index afterwards.

Layer 2: Execution

• **Mode:** `bypassPermissions`
• Each agent gets a specific issue set with file ownership
• Agents write a failing test first that reproduces the bug (prove it is RED for the right reason), then fix, then prove it is GREEN. A regression test that was never red does not prove the fix.
• Run the authoritative gate per the Test Evidence Protocol (`team:evidence.md`): CI-pinned tool versions, integration dependencies provisioned, any skip treated as `UNVERIFIED` (never a pass), and capture command + exit code + summary to `EVIDENCE.md`. "Fixed + tested" is not a valid claim without that evidence.
• Atomic commits per fix: `fix({scope}): {description}`

**Toolkit integration:**

• Check team:toolkit.md for "Systematic Debugging" entry
• Apply systematic-debugging methodology for complex bugs

Layer 3: Fix Verification

L3 agents verify:

• Root cause actually addressed (not just symptom masked)
• No new issues introduced
• Test coverage for the fixed code path, confirmed against `EVIDENCE.md` (the bug-reproducing test actually ran and is now green) — not by reading test descriptions

Regression Tests

Run after all Layer 2 agents complete, per the Test Evidence Protocol (`team:evidence.md`): run the CI-equivalent authoritative gate with integration dependencies provisioned, capture the parsed summary + coverage to `EVIDENCE.md`, and surface skips/`UNVERIFIED` explicitly. Any failing test BLOCKS — loop back to fix (max 3 rounds); do not merely note it in REVIEW-PACKAGE.md.

GSD Integration

When `.planning/` exists, L2 agents follow GSD commit conventions. Include fix context in STATE.md.
