owner-inference

name	owner-inference
description	Infer a suspected owner for a failing test file using CODEOWNERS, git blame, recent commits, and an override map.

Purpose

Deterministic heuristic to identify the likely owner of a failing test file. Used by triage's check_or_create_critical_issue to populate "suspected owner" in new issues.

When to use

When triage creates a critical test-failure item and needs an owner.

Inputs / Outputs

Input: JSON payload { repo_path: ".", file_path: "tests/test_foo.py", commit?: "abc123", confidence_threshold?: 0.3 }

Output: { assignee: string, confidence: 0.0-1.0, reason: string, heuristic: string }

Heuristics (in priority order)

1. Override map — .worklog/triage/owner-map.yaml
2. CODEOWNERS — GitHub-style file
3. Git blame — most frequent author by line count
4. Recent commits — most frequent committer (last 50 commits)
5. Fallback — Build with confidence 0.0

Script

./scripts/infer_owner.py

Example

python3 ./scripts/infer_owner.py --repo . --file tests/test_foo.py --commit abc123
wl show SA-0MPYMFZXO0004ZU4 --json
