build_action_request emitted no tenant field at all. The deployed
secrets-engine.catalog-lane.lifecycle v2 package reads
known_tenant := "tenant:platform"
request_tenant := object.get(input, "tenant", "")
so an absent tenant is not an ignored field, it matches the wrong_tenant
first-denial branch. Every gated action this engine sent would have been
denied -- and the omission also produced a request_digest that could match
no correctly issued decision, since tenant is hashed material. That is the
same class of defect as hashing excluded fields, arriving from the other
direction, and again only a real artifact exposed it.
Found by answering the GLAS-WP-0015 tenant-alignment question instead of
assuming the values lined up.
- REQUEST_TENANT is pinned against the vendored allow envelopes, so a
package retenanting fails a test rather than denying production.
- An empty tenant is refused at build time.
- Accepted policy version moves v1 -> v2. v1 had no tenant rule and failed
open: a rotate under tenant:coulomb returned allow against the deployed
package. flex-auth superseded rather than amended it, because a fail-open
correction has to be visible as a version change. A test pins that a v1
decision is refused.
- Vendored decision_wrong_tenant_deny.json as the denial evidence glas
asked for, with tests that we refuse it on effect before anything else
and that a deny legally carries no lifetime.
docs/tenant-alignment.md states the three tenant values as this repo holds
them. It does not resolve the JWT/store mapping: service_auth.TENANT is
tenant:coulomb, which is exactly the value the package denies. That is
either two layers sharing a namespace format or one wrong constant, and
picking between them without an owner ruling is the fail-open shape
GH-DEC-2026-008 rejected for action vocabularies. Both constants stay as
they are, deliberately not unified.
