//! Native Google Cloud Storage source backend.
//!
//! The `gcs` provider already reaches GCS through its S3 interoperability API,
//! which needs an HMAC key pair. This backend is the other half: it authorizes
//! with a service-account key, the credential most GCS projects actually issue,
//! by minting OAuth tokens through the shared `google-cloud-auth` credential
//! machinery the tier layer already uses.
//!
//! Two GCS surfaces are involved, each for the half it describes best. The read
//! path uses the XML API (`/{bucket}/{object}`), whose responses carry
//! `x-goog-meta-*` user metadata and the `x-goog-hash` digest in one round trip.
//! Listing uses the JSON API (`objects.list`), whose `pageToken` maps directly
//! onto the shared page cursor and whose `prefixes` are the delimiter roll-up.
//! Both accept the same bearer token.
//!
//! `x-goog-hash` carries a base64 MD5 for every non-composite object; it is
//! converted to hex and becomes the head's ETag, so a pulled object is checked
//! against the digest GCS itself computed. A composite object has no MD5, and
//! its ETag is then marked opaque rather than checked.

Azure Blob has no preset; a native provider is deferred (rustfs/backlog#2166).
Every backend answers the same trait contract, pinned by `backend_contract.rs` in `crates/ecstore/src/bucket/on_demand_migration/`, and the three differences that contract allows are the ones documented here.
`azure` differs in two of them. Its ETag is a concurrency token rather than a digest of the bytes, so it is stored as `odm-source-etag` provenance and never used as the expected MD5 of a pulled object — the write-back integrity check falls back to the local digest. And its listing paginates only with an opaque marker: there is no "start after this key" form, so a caller that asks for one gets `Unsupported` instead of a listing that silently starts over.
`gcs_native` differs in the other two. Its listing also has no exclusive "start after" form (`startOffset` is inclusive), so it refuses one the same way. And GCS has no object tagging at all: `policy.copy_tags` finds no tags rather than failing the pull, because GCS custom metadata is already carried by the head mapping. Its ETag is normally usable: the `x-goog-hash` MD5 is converted to hex and checked against the pulled bytes, except on a composite object, which has no MD5 and whose ETag is then treated as opaque.
The "Interop evidence" column names the job in `.github/workflows/on-demand-migration-interop.yml` (rustfs/backlog#2167) that last exercised the preset against a real implementation, and is where a provider difference belongs once the lane finds one. That lane is report-only and scheduled: it runs `crates/e2e_test/src/on_demand_migration/interop_test.rs` — the same case bodies as the merge-gate suite, with the source injected through `RUSTFS_ODM_INTEROP_*` — against a pinned MinIO container, and against each cloud provider whose repository secrets are configured. A provider without secrets is skipped with a note in the run summary rather than failing, so "no difference recorded yet" means exactly that and not "verified clean"; see [ci-gates.md](../testing/ci-gates.md) for the row.
