{
fix(secrets-engine): v2 adds the tenant rule v1 never had
secrets-engine.catalog-lane.lifecycle v1 contained no reference to
input.tenant — not in well_formed, not in the denial ladder, not in a
test. A rotate on lane:glas-primary under tenant:coulomb returned allow
against the deployed package (decision:066e629bbf0c0924).
Found while answering glas-harness's tenant-alignment request, which had
asked for wrong-tenant denial evidence. There was none to return.
Three covers failed the same way: every one of the 29 fixtures carried
tenant:platform, so the suite could not report on the field; T02's own
gate named "wrong-tenant deny" and was recorded done unmet; and the
engine hashes tenant into request_digest but never compares it. Four
other published packages carry the branch — this one was the outlier.
v2 adds wrong_tenant above wrong_system, three Rego tests and three
fixtures (28/28, 32/32). The absent-tenant test caught a second defect
in the first draft: a bare input.tenant != comparison is undefined on a
missing key, so the branch dropped and the ladder reported the wrong
rung. request_tenant := object.get(input, "tenant", "") fixes it.
v2 supersedes rather than amends v1 because the defect failed open: a
consumer pinned to _VERSION=v1 would keep receiving allows with no
signal the rule beneath the version string had changed. The earlier
dual-control correction stayed at v1 because it denied everything.
Replay envelopes regenerated at v2; both request_digest values are
byte-identical, so secrets-engine's digest join needs no re-pinning.
The sweep this prompted found tenant-engine unscoped on tenant as well —
deployed, and verified allowing tenant:coulomb. Not the same fix: its
request tenant names the target rather than the caller, so a constant
would break it. Recorded and carried by FLEX-WP-0022 rather than patched
unilaterally.
FLEX-WP-0021 closes at T05; the pin still serves v1 until a redeploy.

fix(decision): registry facts win over caller-supplied attributes
secrets-engine's first live request rejected our allow: binding.
request_digest is computed over material they never sent, because we
enrich subject and resource from the registry before hashing. Answering
that meant reading the enrichment path, which had a worse defect in it.
Enrichment was additive-if-absent — addAttribute wrote a registry value
only where the request had no value for that key. So where a caller
supplied a key, the caller's value won and the registry's never applied.
Every registry ceiling and allowlist was advisory. Verified against the
shipped ops-warden package, each one added key on an otherwise-denied
request:
max_ttl_hours: 99 registry says 8 -> allowed a 12h certificate
allowed_principals registry allowlist -> disallowed_principal bypassed
allowed_subjects registry allowlist -> unknown_subject bypassed
The third is the one to read twice: a subject the registry does not know
authorized itself by naming itself in the allowlist it was being checked
against.
Not remotely reachable today — the PEP builds the CheckRequest,
ops-warden sends no resource.attributes, and enforce admits one identity.
It is a defence-in-depth failure: any path that lets attacker-influenced
data into a CheckRequest field became a full policy bypass rather than a
bounded input problem. Callers sending resource.attributes is not
hypothetical; secrets-engine does it on every request.
Registry facts now win, and diagnostics.registry_overrode names every
displaced key, because a registry that silently discards a contradicting
claim hides that a caller asserted authority it did not have.
subject.type is carved out, and the reason is a finding of its own.
Making the registry win there denied every secrets-engine allow: the
registry's type is CARING vocabulary (Human, Agent, Automation, Service)
and the request's is the protected system's actor vocabulary (service,
adm, agt, atm). Two fields sharing a name; substituting one for the other
is translation rather than identity, which GH-DEC-2026-008 ruled against.
Note what surfaced it — the registry's type had been dead data since the
field existed, because the caller's value always won.
Also publishes binding.submitted_request_digest, over the request exactly
as sent. request_digest was published as the consumer replay test and
cannot be one. Nothing is lost hashing the pre-enrichment form:
enrichment is a function of the request and the snapshot, and
registry_snapshot_digest already pins the snapshot.
Existing pins do not move. All three replay fixtures' request_digest and
approval_binding_digest values are byte-identical — those requests
contradict no registry fact. A field to add, not a value to correct.
Regression tests verified failing against the old behaviour before being
kept. FLEX-DEC-2026-012; FLEX-WP-0025 carries the residual, that a policy
still cannot tell a fact from an assertion.
