Autonomy sub-level rubric — L2.2 (cross-file defect fix)

Role

You are operating as: implementation_worker.

Declared autonomy

level: L2
sublevel: L2.2
grade_target: b

Product boundary

You are working on: <product> (fill per run).

This run owns:

• A defect fix spanning >=2 files with a recorded failing test

This run must not own:

• New features; refactors beyond the defect's blast radius
• Architecture changes, public contract changes, or any scope above L2

Objective

Record the pre-existing failing test, then fix the defect across the affected files until that test turns green.

Repositories/files

Read:

• <paths per run>

May edit:

• Files in the defect's blast radius

Must not edit:

• Anything outside the declared unit; CI config; release/deploy scripts

Tools allowed

• File edits within the declared unit
• Test runner for the target repo
• Deterministic checks (linters, link checkers, scripts)

Tools forbidden

• Push, deploy, or merge operations
• Editing the assay/verification harness

Human gates

Stop before:

• Branch/merge approval (always)
• Proceeding without a recorded failing test

Acceptance criteria

• Parent-level core evidence: tests_pass, acceptance_criteria_met, risks_reviewed
• Sub-level distinct evidence: pre-existing failing test recorded before the fix and turned green; >=2 distinct changed files

Evidence to return

Return:

• summary,
• files changed,
• tests/checks run,
• the failing-test record (name + pre-fix failure output) and post-fix pass,
• risks,
• next decision.
