When `clientProvisioning.enabled=false`, the registrar logs a warning and downgrades the capability at runtime. - **Bootstrap seeding + audits.** `bootstrap.*` mirrors the provisioning contract for human operators: the plug-in writes `uid={username}` entries under `bootstrap.containerDn`, applies `staticAttributes` placeholders (`{username}`, `{displayName}`), and mirrors deterministic audit records to PostgreSQL (`ldap_bootstrap_` table by default) with hashed secrets (`AuthoritySecretHasher`). Bootstrap only lights up when (1) the manifest advertises the capability, (2) `bootstrap.enabled=true`, **and** (3) the plug-in proves the bind account can add/delete under the configured container. Otherwise the capability is silently downgraded and health checks surface `capabilities=bootstrapDisabled`. -- **Capability proofing.** On startup the plug-in performs a short-lived LDAP write probe (add→delete) inside each configured container. If either probe fails, the respective capability (`clientProvisioning`, `bootstrap`) is removed, `ClientProvisioning` stays `null`, and `CheckHealthAsync` reports `Degraded` until permissions are restored. This keeps read-only deployments safe while making it obvious when operators still need to grant write scope. +- **Capability proofing.** The plug-in performs short-lived LDAP write probes (add->delete) inside each configured container and caches the result for `capabilityProbe.cacheTtlSeconds`. Probe timeouts are controlled by `capabilityProbe.timeoutSeconds`.

This keeps read-only deployments safe while making it obvious when operators still need to grant write scope. +- **Connection timeout.** `connection.timeoutSeconds` controls the LDAP connection timeout so deployments can tune for slow directories or stricter fail-fast posture. - **Sample manifest + binaries.** The curated manifest lives at `etc/authority.plugins/ldap.yaml` and demonstrates TLS, regex mappings, caching, and audit mirror options. Offline Kits copy both the manifest and the compiled plug-in into `plugins/authority/StellaOps.Authority.Plugin.Ldap/` so operators can drop them straight into air-gapped composer deployments. +### 6.5 SAML plug-in quick reference (PLG7.IMPL-006) + +- **Metadata fetching.** `idpMetadataUrl` is used to load signing certificates when explicit IdP certs are not configured. Metadata fetches require HTTPS by default (`requireHttpsMetadata=true`) and respect `metadataTimeoutSeconds` and `metadataRefreshInterval`. +- **Unsupported flags.** `requireEncryptedAssertions`, `signAuthenticationRequests`, and `signLogoutRequests` are not supported yet; keep them disabled until signing/encryption flows are implemented. +- **Session cache isolation.** Session cache keys include the plugin name to avoid collisions when multiple SAML providers are configured. + ## 7.

limit buckets, token stores, indexes, set stores, event streams, and idempotency keys; test state can leak across runs. `src/Router/__Libraries/StellaOps.Messaging.Transport.InMemory/InMemoryQueueRegistry.cs` +- MAINT: InMemoryMessageLease.RenewAsync uses DateTimeOffset.UtcNow instead of the TimeProvider used elsewhere, making lease renewal nondeterministic. `src/Router/__Libraries/StellaOps.Messaging.Transport.InMemory/InMemoryMessageLease.cs` +- MAINT: SubscribeAsync compares entry IDs lexicographically; sequence suffixes can misorder once digits grow, causing missed or duplicated events. `src/Router/__Libraries/StellaOps.Messaging.Transport.InMemory/InMemoryEventStream.cs` +- MAINT: Pending

GetByRankAsync claims Redis-style negative index handling but does not adjust start/stop; negative inputs return incorrect ranges.

tenant/correlation/idempotency/headers because BuildEntries is called with null options, losing metadata. `src/Router/__Libraries/StellaOps.Messaging.Transport.Valkey/ValkeyMessageQueue.cs` +- MAINT: GetPendingCountAsync does not ensure consumer group creation; calling it before any enqueue/lease can throw. `src/Router/__Libraries/StellaOps.Messaging.Transport.Valkey/ValkeyMessageQueue.cs` +- MAINT: Rate limiter window key divides by (long)policy.Window.TotalSeconds; sub-second windows cause divide-by-zero and the implementation is fixed-window despite the sliding-window comment. `src/Router/__Libraries/StellaOps.Messaging.Transport.Valkey/ValkeyRateLimiter.cs` +- MAINT: Cache SetAsync uses TimeSpan.MaxValue for "no TTL", which can overflow or be rejected by Redis; should use null for no expiration. `src/Router/__Libraries/StellaOps.Messaging.Transport.Valkey/ValkeyCacheStore.cs` +- MAINT: Pattern invalidation uses only the first server endpoint; clusters or replicas will be partially cleaned. `src/Router/__Libraries/StellaOps.Messaging.Transport.Valkey/ValkeyCacheStore.cs` `src/Router/__Libraries/StellaOps.Messaging.Transport.Valkey/ValkeyRateLimiter.cs` +- MAINT:

`src/Notify/__Libraries/StellaOps.Notify.Queue/NotifyDeliveryQueueHealthCheck.cs` `src/Notify/__Libraries/StellaOps.Notify.Queue/NotifyQueueServiceCollectionExtensions.cs` +- Proposed changes (optional): add explicit test SDK reference or document runner choice, replace random IDs/timestamps with fixed values, and add coverage for DI/health/metrics plus claim/renew flows. +- Disposition: waived (test project; no apply changes). +### src/Notify/__Libraries/StellaOps.Notify.Storage.InMemory/StellaOps.Notify.Storage.InMemory.csproj +- MAINT: TreatWarningsAsErrors is disabled for the in-memory storage library. `src/Notify/__Libraries/StellaOps.Notify.Storage.InMemory/StellaOps.Notify.Storage.InMemory.csproj` +- MAINT: AddNotifyInMemoryStorage computes a persistence config section but never uses it; the persistence registration stub is a no-op, so configuration is ignored and the "delegates to persistence" description is misleading. `src/Notify/__Libraries/StellaOps.Notify.Storage.InMemory/ServiceCollectionExtensions.cs` +- MAINT: In-memory repositories enumerate ConcurrentDictionary/ConcurrentBag without deterministic ordering and use `DateTimeOffset.UtcNow`, which makes results vary across runs and complicates deterministic tests. `src/Notify/__Libraries/StellaOps.Notify.Storage.InMemory/Repositories/InMemoryRepositories.cs` +- MAINT: StorageInitializationHostedService logs "PostgreSQL backend" even for in-memory storage. `src/Notify/__Libraries/StellaOps.Notify.Storage.InMemory/StorageInitializationHostedService.cs` +- TEST: No test project exists for this library; repository ordering, locking, and timestamp behavior are unverified. `src/Notify/__Libraries/StellaOps.Notify.Storage.InMemory/StellaOps.Notify.Storage.InMemory.csproj` +- Proposed changes (pending approval): enable warnings-as-errors, make the storage registration/config meaningful (or remove the unused config/persistence stub), normalize deterministic ordering/time sources for in-memory repositories, fix the hosted-service log message, and add coverage for repository behavior and determinism. +- Disposition: pending implementation (non-test project; apply recommendations remain open). ## Notes - Example projects waived at requester direction; APPLY tasks closed with no changes. - APPLY tasks remain pending approval of proposed changes for non-example projects. @@ -3579,3 +3939,11 @@ + + + + + + + + diff --git
