Three fixes, all on the path between "the migration looks ready" and "the
migration is ready".

verify-parity.sh never sourced env-topology.sh, so TG_BAO_APPROLE was unset and
render-secrets-openbao.sh fell through to the bare default -- prod's credential
-- for every environment. On vps2 that made `--env beta` authenticate as
tg-prod and take a 403 from tg-host-prod.hcl on thermograph/data/env/beta.
`--all` failed the same way, taking dev with it. deploy.sh and
deploy-stack.sh always sourced it; only the verifier did not, which is the
worst place for the omission: the tool whose job is to notice divergence was
itself diverging from the path it verifies. It now calls thermograph_topology
per environment and takes TG_SKIP_COMMON from there rather than re-deriving it.

infra-sync.yml renders all three env files on every push touching infra/**, and
none of its three jobs sourced env-topology.sh either. TG_SECRETS_BACKEND was
therefore unset and render-secrets.sh:44 defaulted to sops. Flipping the
selector would have changed deploy.sh and deploy-stack.sh but not this
workflow, which would have kept re-rendering from SOPS -- silent while parity
holds, and a hard failure the moment the SOPS files are retired. The one-line
cutover the README describes was never sufficient on its own.

ops-cron.yml gains a secrets-parity job: prod and beta from vps2, dev from
vps1, nightly, failing loudly on a mismatch. README.md called this the gate for
a cutover; nothing implemented it. A gate that exists only in prose gets
satisfied by assertion. It grants CI no vault access -- the host renders, CI
only asks it to.

First measured run, immediately after the verifier fix:

  dev   12 keys  PASS, byte-identical
  beta  24 keys  FAIL, 3 values differ
  prod  32 keys  FAIL, 3 values differ

The same three keys on both: THERMOGRAPH_S3_SECRET_KEY,
THERMOGRAPH_LAKE_S3_SECRET_KEY, THERMOGRAPH_VAPID_CONTACT. All three live in
common.yaml, seeded 2026-07-31 02:30Z -- before the Contabo rotation landed.
dev passes because dev never layers common. One `seed-from-sops.sh --env
common` fixes beta and prod together, and the 7-day clock starts after that.
