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.
Closes FLEX-WP-0022 (T01, T02 done). Also records TEN-IN-0004 and
SECRETS-IN-0002 on FLEX-WP-0020 and acknowledges the GH-DEC-2026-017

Extend the tenant-engine write-API policy package with tenant.update,
tenant.retire, and tenant.reactivate, the three actions TEN-WP-0005
introduced. Until now every lifecycle mutation resolved to deny
unknown_action, blocking TEN-WP-0005-T05 production rollout.
- policy_package.md: three actions in valid_actions and frontmatter;
CARING capabilities extended with EditAny/Archive/Restore
- protected_system_manifest.yaml, subject_manifest.yaml, and the rebuilt
registry_snapshot.json carry all seven actions
- docs/tenant-engine-action-vocabulary.md documents the HTTP surfaces
- 8 new fixture pairs and 5 new Rego tests, including action-drift
guards (tenant.retired, tenant_update -> unknown_action)
T02 decision, recorded in policy_package.md: tenant.retire does NOT get
stricter authorization yet. With one service subject and no assurance
claim in the CheckRequest there is nothing stricter to check, and a
condition the sole caller always satisfies would falsely read as
separate control. Retirement is reversible and non-destructive. Revisit
on KEY-WP-0005 assurance claims or a second operator subject.
Verified: 11/11 Rego tests, 16/16 fixtures, go test ./... green, gofmt
and go vet clean. End-to-end against a live serve with a real
tenant-engine through the unmodified FlexAuthWriteAuthorizer: update
6176c39c2f4d7b15, retire 8a801b8ee8455080, reactivate c64cf3713cecd970
all allow; unregistered actor denied unknown_subject
(59d3e99c6416be89, 403 write_denied).
Handoff revision for TEN-WP-0005-T05: package
tenant-engine.write-api.mutate v1 (ready, caring-0.4.0-rc2).
