Four tasks forming a DAG for the dynamic resource ownership model (ADR-050):
1. core/ownership-store-trait (no deps) — OwnershipProvider (sync read) +
OwnershipStore (async write) traits + InMemoryOwnershipStore + OwnershipError
in alknet-core; fourth instance of the repo/adapter pattern (ADR-033)
2. call/registry/operation-spec-resource-id-path (no deps) — add
resource_id_path: Option<String> to OperationSpec (JSON pointer into
input for resource ID extraction)
3. call/registry/access-control-ownership-check (depends on 1) — update
AccessControl::check signature to accept resource_id + OwnershipProvider;
backward compatible (ownership=None falls back to static Identity.resources)
4. call/registry/dispatch-resource-id-extraction (depends on 2, 3) — wire
dispatch path to extract resource_id from input via spec.resource_id_path
and thread OwnershipProvider to check(); OperationContext gains ownership
field
Tasks 1 and 2 can run in parallel (different crates, no deps). Task 3
depends on 1. Task 4 depends on 2 and 3. Validated: no cycles, 90 tasks total.
