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.
