Status: stub. Bytes are not yet mirrored to this CID address. The hash is computed over the metadata block above only. Read the original at the upstream URL. Full bytes-mirroring ships with scripts/mirror.ts in Week 2+ (see ARCHITECTURE.md).
Stub citation — bytes not yet mirrored. /c/<cid> redirects readers to the upstream URL until the mirror script runs (Week 2+). The hash is computed over the `canonical` sub-object and verifies via lib/cid.ts.
Probe history · upstream fingerprint
We periodically fetch the upstream URL and store: HTTP status, response headers, and SHA-256 of the body. The body itself is never stored (copyright-safe). Future readers can re-fetch the upstream and compare hashes to detect drift.

Body hash is a snapshot at probedAt. For dynamic pages (e.g. search results) the hash will differ on later fetches — that is information, not error. Original body bytes are NOT stored (copyright-safe).
