# Capability Spec Delta: logging (spec-conformance)

**Package**: `@suaveplan/logger`
**Status**: PROPOSED

This delta annotates each existing requirement in `openspec/specs/logging/spec.md` with a `**Verified by:**` line. No requirement semantics change.

## MODIFIED Requirements

(See `openspec/specs/logging/spec.md` for the full requirement bodies.)

| Requirement | Verified by |
|---|---|
| LG-01 Log levels | `src/abstract/abstract-logger.test.ts` AND `src/record/log-record.test.ts` |
| LG-02 Structured log record | `src/record/log-record.test.ts` |
| LG-03 Pluggable sinks | `src/sink/sink.test.ts` AND `src/abstract/abstract-logger.test.ts` |
| LG-04 Console sink | `src/sink/sink.test.ts` |
| LG-05 JSON (NDJSON) sink | `src/sink/sink.test.ts` |
| LG-06 Buffered sink | `src/sink/sink.test.ts` |
| LG-07 Redaction engine | `src/redaction/redaction.test.ts` AND `src/abstract/abstract-logger.test.ts` |
| LG-08 Sampling | `src/sampling/sampling.test.ts` AND `src/abstract/abstract-logger.test.ts` AND `src/abstract/abstract-logger.spec-conformance.test.ts` |
| LG-09 OpenTelemetry correlation | `src/otel/otel-context.test.ts` |
| LG-10 Injectable clock and RNG | `src/abstract/abstract-logger.test.ts` |
| LG-11 Metrics | `src/abstract/abstract-logger.test.ts` |
| LG-12 OTel instrumentation | `src/abstract/abstract-logger.spec-conformance.test.ts` |
| LG-13 Structured errors | `src/errors/logger-error.test.ts` |
| LG-14 i18n / keyed messages | `src/abstract/abstract-logger.test.ts` (string MUST path; the optional `{ key, args }` overload is forward-looking) |
| LG-15 Error bridge | `src/error-bridge/error-bridge.test.ts` |
| LG-16 Factory | `src/factory/factory.test.ts` |
| LG-17 Init helper | `src/init/init.test.ts` |
| LG-18 Property-based tests | `src/redaction/redaction.test.ts` AND `src/sampling/sampling.test.ts` AND `src/record/log-record.test.ts` |
| LG-19 Benchmarks | `src/__benchmarks__/logger.bench.ts` (file existence) AND hot-path correctness via per-feature unit tests |
| LG-20 Tree-shake safety | `src/abstract/abstract-logger.spec-conformance.test.ts` |

## Newly added tests in this change

- `src/abstract/abstract-logger.spec-conformance.test.ts` — pins LG-12 (recording MeterProvider, asserts `logger.records_total`, `logger.record_size_bytes`, `logger.dropped_total` fire with documented attributes) and LG-20 (`sideEffects: false`, subpath exports, dist shape).
