cxymds 17ddecb075 fix(ecstore): gate shard integrity and preserve legacy recovery (#7741)
* fix(ecstore)!: bind bitrot shards to immutable part identities

Verify part, coding-index, and block identity across write, GET, and Heal
paths. Preserve identities across metadata-only copies and repair, include
them in multipart quorum selection, and require payload proof for receipts.

Keep legacy decoding with conservative parity and target-digest validation,
and document its unsupported cases and additional verification I/O.

BREAKING CHANGE: New bound-v1 shards require compatible readers throughout
the fleet. Legacy objects without sufficient integrity evidence return an
error; binary rollback after new writes requires verified data migration.

Refs: rustfs/backlog#2497

* fix(ecstore): preserve shard framing with independent integrity

Commit immutable part-generation Merkle roots and replicated proof indexes without changing existing checksum frames. Verify reads, reconstruction and Deep Heal against metadata quorum; keep legacy reads and explicitly defer unproven legacy data repair.

Preserve multipart rollback generations, require acknowledged durable index publication, and add decoder compatibility and donor-shard regression coverage.

* fix(heal): verify protected partial-write replay

Operations

Operational runbooks live under operations/. Replication operators should start with:

Runbook Use it for
Site replication operations Health fields, pending operations, outage recovery, re-pair admission, IAM/SSE boundaries, and upgrades.
Replication target check Validating an S3 destination and version fidelity before enabling replication.
Replication object size limits Multipart routing, large-object limits, and retry characteristics.
Replication outbound transport Integrity headers, generic target behavior, and transport knobs.

Other runbooks remain grouped by filename in operations/; architecture pages link to the relevant runbook where a cross-boundary procedure is required.

For storage dashboards, see Storage metrics and observer selection: drive ownership, snapshot freshness, counter queries, and rolling upgrades.

For optional shard commitments, see Independent shard integrity rollout: activation, legacy repair results, multipart mode changes, and rollback limits.
