An archive that only serves its own rendition of a page returns `createUnsupportedContentResponse` with the reason instead. - **A stored capture is the response as it travelled**: a WARC record keeps the chunked framing and the `Content-Encoding` the server used, so reading its text means undoing both before the charset is applied. Playback endpoints do it for you, which is why only the Common Crawl path carries this. - **The library decodes, a surface renders**: charset decoding, WARC unwrapping and transfer/content encodings are library work, and the body it returns is text; `htmlToText`, clipping to `maxChars` and the untrusted-data fence are applied in `tool-operations.ts`, so a library consumer keeps the whole document rather than a reader's view of it. Text is the contract, not the raw bytes: a capture that is not text decodes lossily and its bytes stay behind `_meta.rawSnapshot` or the WARC coordinates. - **The MCP process does not trust its own cwd**: `src/commands/mcp.ts` calls `setConfigCwd(homedir())` because a client spawns the server in an arbitrary checkout, and c12 executes the `archives.config.ts` it finds. `consola.level` is pinned there too — stdout carries the JSON-RPC frames. @@ -154,6 +155,7 @@ pnpm release # test + changelogen + publish - **Defaults**: concurrency=3, batchSize=20, timeout=10000ms, retries=1, cache TTL=7 days.
