* feat(scanner): add raw page owner index
Add a serializable raw enumeration page owner index for scanner resume work.
The index exposes unsupported, building, and ready states, validates committed page identity by recomputing digests, and uses generation checks for CAS-style page commits.
Focused tests cover small-budget restart progress, page digest/source drift rejection, corrupt deserialized state, CAS failure, precommit crash, empty sources, and invalid entry boundaries.

* feat(scanner): persist raw page owner resume state (#7379)
Wire the scanner raw enumeration partial-cache writer to the raw page owner index so interrupted bucket walks can retain validated page-builder state across scanner restarts.
Keep complete owner sources terminal-only, add partial-source ingestion for in-progress raw directory reads, and validate the persisted page index through bucket checkpoint preparation.

* test(scanner): fence segment producer observations (#7381)
Require the segment observation fixture to carry source, incarnation, key-format, baseline, process epoch, generation-window, gap, overflow, and producer-coverage proof before accepting a narrowed proposal. Keep the diagnostic path fixture-only and remove its ordinary stderr output.

* test(heal): cover MRF crash successor matrix
Add process-boundary MRF replay coverage for the successor snapshot window after a retained startup journal is flushed but before cleanup deletes it. Extend the mixed authoritative/legacy reader fixture with a scoped v2 journal epoch to pin the no-merge contract.

* test(heal): cover service-kill MRF replay (#7380)
Add a Unix process fixture that waits after publishing the pending MRF successor snapshot, then is terminated by the parent before restart replay.

* test(heal): cover transport-lost start receipts (#7371)
Add gRPC transport fault fixtures for heal-control start admission. The tests distinguish pre-admission transport loss from post-admission response loss, then verify exact envelope retries reuse the canonical receipt while fresh forceStart requests create distinct tasks.

* test(scanner): add crash-restart heal evidence case (#7370)
* test(scanner): add crash-restart heal evidence case
Add a distinct W21 background target crash case to the scanner/heal evidence registry and oracle path.
Keep the existing restart lane on graceful process restart, keep the crash lane on hard kill, and make the wiring checker reject evidence/oracle mismatches.

* test(scanner): support older Python wiring checks
Let the scanner/heal evidence wiring checker run under Python 3.9/3.10 by falling back to tomli and chunked SHA-256 hashing when the Python 3.11 standard APIs are unavailable.

* fix(scanner): reject stale raw page source seeds (#7382)
Do not prefill a resumed raw page owner with previously indexed entries when starting a new raw directory observation pass. The next pass must observe the same prefix again before the page index can advance; otherwise the index is discarded fail-closed.

* fix(scanner): defer raw page revalidation until observed (#7384)
A resumed raw page owner index must not prefill entries from older cache state, but it also must not discard a valid multi-entry index before the current raw directory pass has observed enough entries to prove identity. Track the persisted index floor and only run the strict owner identity check once the current pass reaches that floor.

Add a durable raw enumeration cursor shape to scanner usage metadata and validate it against bucket identity, source, bounds, version, and page digest before preserving it across checkpoint preparation.
Keep empty cursor metadata omitted so existing pinned .usage-cache.bin bytes stay unchanged, while legacy readers still ignore the additive field when it is present.

Lower the default scanner cache save timeout so the derived usage persistence budget stays inside the effective distributed publication lease window.
Add focused regressions for the default publication budget and bootstrap-pending observational baselines, and update operator docs with the new default.

* refactor(data-usage): ReplicationStats -> ReplicationTargetUsage
Rename the data-usage crate's ReplicationStats to ReplicationTargetUsage.
Serde field names are byte-identical (only the Rust type name changed;
field identifiers that rmp encodes are untouched). An rmp round-trip test
guards against future drift.
Scanner test imports updated to match.
* style: cargo fmt
Split the 3655-line data_usage_define.rs (59% inline tests) into a
canonical foo.rs + foo/ module tree with zero behavior change:
- data_usage_define.rs (~950): cache constants and revision helpers,
the data-usage tree types, DataUsageCacheInfo with its hand-written
Serialize, the in-memory tree operations, dui, and marshal/unmarshal
- data_usage_define/persistence.rs (~580): the load/backup/restore
ladder (load, try_load_inner, revision_for_path) and the CAS save
path with its retry policy and save metrics
- data_usage_define/tests.rs (~2155): the inline test module as a child
module
All module paths are unchanged (the lib.rs data_usage_define::* glob
re-export and every crate::data_usage_define:: consumer resolve as
before). The hand-written map-encoded Serialize for
DataUsageCacheInfo is moved byte-for-byte per the AGENTS.md
cross-cutting invariant; on-disk names and the cache key format const
stay in the root. Four persistence helpers used by tests gain
pub(super), whose scope equals the old single-module privacy domain.
Code is moved verbatim apart from those markers, per-module import
headers, and rustfmt re-wraps.
