Step 9 av v4.1-execute (Wave 2, Session 3). Pure function transformToPrometheus(records) → Prometheus text-format 0.0.4. Hard rules: - NO client-side timestamps (research/01 node_exporter#1284 mitigation) - Allowlist-redacted records ONLY (caller responsibility — Step 11 enforces) - UTF-8 metric names normalized: lowercase, [.\\-\\s] → _, voyage_ prefix - Empty input → empty string output - Sorted output for determinism (snapshot-test-friendly) Heuristic metric typing: - counter: *_total, *_count, *_passed, *_failed, *_skipped - histogram: *_ms, *_duration, *_p\\d+, *_seconds - gauge: everything else (Prometheus convention) Snapshot: tests/fixtures/expected.prom byte-for-byte match. Regenerate: node scripts/gen-expected-prom.mjs > tests/fixtures/expected.prom Tester (6 nye, baseline 400 → 406): - Snapshot byte-for-byte match (SC #12) - Empty input handling (null, undefined, []) - Allowlist-redaction sanity (post-bash-stats uten command_excerpt) - NO client-side timestamps (token-count-assertion per linje) - normalizeMetricName edge-cases - Determinism (identisk input → identisk output) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
