tenant-engine named the relation in TEN-DEC-2026-002: `tenant` is the target
tenant record and always equals `resource.id`; the write API is cross-tenant
by design and `tenant.guardrail.read` does not differ. v2 carried no tenant
rule and a constant fixture tenant, so the deliberate scope and an omitted
rule were indistinguishable.
tenant-engine.write-api.mutate v3 (FLEX-DEC-2026-016):
- allowed requires tenant_is_target; a mismatch or absent tenant is denied
tenant_not_target (object.get, so an absent key names the right cause).
- the cross-tenant scope is stated in the package and quantified by
test_tenant_never_changes_effect over every action, three subjects and
four tenants, with guards against passing by denying everything.
- fixtures rotate tenant across four tenants; five cross-tenant allows and
two tenant_not_target denies added (42 fixtures, 33 tests, all pass).
- user-engine's tenant:platform exclusion is named as a fixed-record rule,
not a subject/tenant relation, and tested separately.

FLEX-WP-0020-T04: reuse-surface is the first owner to return a live work-record
(REUSE-WP-0023, two tasks, both deliberately in wait). Recorded in the handoff
evidence and verified rather than taken on report — the hub record is active,
access-engine raw returns 404, flex-auth returns 303, so the rename has not
landed and their refusal to pre-rewrite the federation source URL is correct.
That refusal changed the plan rather than only their side: flipping an enabled,
publish-passing source before the rename drops a live capability from the
composed federated index, so the source rewrite is ordered after T06, and
flex-auth owes them a ping when access-engine serves the capabilities index.
Nine owners remain pending; T05 stays blocked.
FLEX-WP-0022-T01: re-asked tenant-engine what CheckRequest.tenant denotes on the
write API, stating that "none" is a complete answer. Their code copies tenant_id
onto both tenant and resource.id, but that is observation, not admission, and
encoding a rule from it would make flex-auth the author of their tenancy model.

FLEX-WP-0020 T01-T03: fresh preflight is zero-blocker, repository-only
scope is FLEX-DEC-2026-013, concurrent work is FLEX-DEC-2026-014.
T04 handoff requests are posted; owner work-records are still required.
T06 stays behind the exact human confirm string and a post-commit preflight.
