… binaries - Add internal/authorization/policy owning the embedded Casbin model, policy matrix and dev fixtures, with Seed, LoadFixtures and MissingRules - Add cmd/authorizationseed and cmd/authorizationfixtures (billingseed pattern), wired into just seed / just fixtures - Service startup no longer writes policies; it logs and fails the startup health probe when the in-memory matrix lacks embedded rules Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

- Around line 45-48: Configure the authorization deployment to use
`/authorization/health/startup` as its startup probe and
`/authorization/health/ready` as its readiness probe; if it cannot gate traffic
with a startup probe, include the policy check currently registered in
`startupChecker` in `readyChecker` so readiness fails when the policy matrix is
missing.
Review comments at @internal/authorization/policy/policy.go:
- Around line 114-115: Update MissingRules to compare the enforcer’s persisted p
rules with the embedded policies, and report any unexpected rules as well as
missing embedded rules. Keep the existing HasPolicy checks for required rules,
ensuring stale rules such as the obsolete viewer delete policy cannot pass the
startup policy check.
Review comments at @internal/authorization/policy/seed_test.go:
- Around line 18-19: Update the test using newPersistentEnforcer to create the

RemovePolicies, then call Seed again to exercise repair of missing rows.
Preserve the existing assertions that verify the policies are restored.

Gate authorization traffic on policy health.
The policy check runs only in startupChecker. When the database, gRPC, and Kafka checks are healthy, /authorization/health/ready can return HTTP 200 even when the policy matrix is missing. The repository's Compose/Traefik deployment has no probe or health gate and routes authorization traffic directly to the service.
Configure the deployment to use /authorization/health/startup as its startup probe and /authorization/health/ready as its readiness probe. If the deployment cannot gate traffic with a startup probe, include the policy check in readyChecker.

Replace MissingRules with DetectDrift, which also reports p rules in the enforcer that are absent from the embedded matrix. Make the missing-row repair test seed the database before removing rules. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

Summary
The authorization service used to sync the Casbin policy matrix (
policy.csv, with pruning) on every start, and loaded dev memberships (policy_fixtures.csv) whenAppEnv=development. This PR moves both out of startup and follows the repo's seed vs fixtures convention, matchingbillingseed/billingfixtures.Changes
internal/authorization/policy(new package)model.conf,policy.csvandpolicy_fixtures.csv. They moved fromapp/;go:embedcan't reach parent directories, so the files sit next toembed.go.Seed(e): adds the matrix (p+g2) and prunes staleprows. Idempotent.gmembership rows are never pruned.LoadFixtures(e): add-only load of dev memberships.MissingRules(e): returns the embeddedp/g2rules that are missing from the enforcer's in-memory policy.app/policysync.goandapp/bootstrap_test.go.App.BootStrapPoliciesandApp.LoadFixturesare removed.New binaries
cmd/authorizationseed+internal/authorizationseed: mandatory data (the role→permission matrix). Runs in every environment, prod included.cmd/authorizationfixtures+internal/authorizationfixtures: dev-only memberships. Assumes seed has already run.NOTOPIA_AUTHORIZATIONSEED_*/NOTOPIA_AUTHORIZATIONFIXTURES_*), wire, and nx targets (gen:wire,run,build,lint).justfile:seed-authorizationis now part ofjust seed, andfixtures-authorizationpart ofjust fixtures.Service startup
NewServerno longer writes policies, so the service doesn't need write access to the policy table at boot.policycheck on/authorization/health/startupfails until the matrix is present.Config flattening
internal/{billingseed,billingfixtures,authorizationseed,authorizationfixtures}: theconfig/subpackage is folded into the parent package (config.go, withNewrenamed toNewConfig). These one-shot binaries don't need a separate config package.Design notes
Why the probe checks memory, not the DB. The Casbin enforcer loads
casbin_ruleonce at boot and never watches the DB (seestory/casbin-policy-not-watching-db.md). If the probe queried the DB, a pod that started before the seed would turn ready while its in-memory matrix is still empty, and every check would be denied. Checking memory keeps the probe failing until the pod reloads.Why log instead of crash. A failing startup probe already makes the kubelet restart the container (after
failureThreshold × periodSeconds), and the restart reloads the seeded policy. That's the "seed first, then start/restart" rule from the story. Crashing would reach the same restart, but with a less specific CrashLoopBackOff signal instead of "startup probe failed: policy matrix is missing N rules".Known limitation (unchanged by this PR). Pods that are already running don't notice a later seed, and multiple instances don't see each other's membership writes. Either a rollout/restart after seeding or a Casbin watcher (Redis or Postgres
LISTEN/NOTIFY) is still required before scaling authorization beyond one replica.Local dev impact
