 - Added `disable-model-invocation: true` to the installable skill metadata for hosts that support manual-only skill invocation.
 - Documented the boundary between the static agent skill bundle and Briefprint runtime caches under `--cache-dir`.
 - Aligned README cache-dir examples, including benchmark receipts, under `.cache/briefprint`.
+- Bumped runtime and skill metadata to `0.5.0`; cache keys include the skill version, so prior `0.4.x` document-summary and rendered-output cache entries cold-start after upgrade.

 숫자는 솔직하게 봐야 합니다. 이 결과는 로컬 harness의 토큰 추정치입니다. 실제 청구 비용을 보려면 provider usage, Codex CLI/OTel, 또는 사용하는 호스트의 telemetry와 함께 비교해야 합니다. 벤치마크의 품질 체크는 actions, decisions, risks, metrics에 대한 가벼운 smoke check이며 의미론적 정확도 점수는 아닙니다.

+Rows with `0` summarizer calls and `0` cache-miss input tokens are intentional: they show that rerenders and repeated briefs reuse cached structured state instead of re-reading unchanged documents.

 Honest number warning: these are deterministic local estimates from the benchmark harness, not provider billing telemetry. Use OpenAI/provider usage or host telemetry when exact billing matters. The benchmark also includes lightweight quality smoke checks for obvious actions, decisions, risks, and metrics; it is not a semantic accuracy score.
