* fix(credentials): harden credential driver security, correctness, and performance

Address review findings from the credential storage drivers PR:

- Route additional_credentials through the driver on refresh to prevent
  silent data loss for multi-credential providers (e.g. AWS STS)
- Clean up stored credential handles on CAS failure during refresh to
  prevent orphaned secrets in external backends
- Enforce namespace validation in the Kubernetes Secrets driver to
  prevent cross-namespace credential access when allow_reference_namespace
  is not enabled
- Cache Vault Kubernetes auth tokens with 80% TTL to avoid re-authenticating
  on every credential operation
- Parallelize resolve_credentials in all three drivers using try_join_all
  for faster sandbox startup
- Add existingSecret support for the KEK Secret to fix helm template/GitOps
  workflows where lookup returns empty and regenerates the key
- Document RBAC blast radius for the Kubernetes Secrets credential driver
  and recommend a dedicated namespace

* fix(credentials): add optimistic concurrency, fix thundering herd, parallelize operations

Use resourceVersion optimistic concurrency with retry loop for K8s
Secret ownership checks to prevent TOCTOU races. Switch Vault token
cache from RwLock to Mutex with double-check pattern to prevent
thundering herd on cache miss. Parallelize credential store and delete
operations across independent keys using try_join_all.

* fix(credentials): handle partial failures, add delete retry, consolidate cleanup

Replace try_join_all with join_all in credential store/delete operations
to handle partial failures — successfully-stored handles are cleaned up
when another key fails. Add retry loop with conflict detection to
db-credstore delete_credential, matching the K8s driver pattern.
Consolidate 4 manual cleanup_pre_stored_provider_credentials call sites
into a single error handler using an async block. Remove inconsistent
.trim() from db-credstore validate_handle_owner.

* fix(credentials): fix retry loop guard and remove unprotected validation

Remove attempt-count guard from 409/Aborted match arms in retry loops
so the post-loop Status::aborted error is reachable after exhausting
retries. Previously, last-attempt conflicts fell through to the
catch-all error arm, producing misleading Status::unavailable errors.

Remove duplicate validation calls that ran after
prepare_provider_credential_update but outside the cleanup-protected
async block, which would leak pre-stored handles on failure.

* fix(credentials): add workspace/provider UUID to credential backend paths

Include workspace and provider ID in credential backend object paths to ensure
cross-workspace uniqueness and prevent credential collision (GATOR-1806c9be-01).

- Updated credential driver proto to include workspace and provider_id fields
- Modified Vault driver to include workspace/provider_id in managed_secret_path
- Modified Kubernetes Secrets driver to include workspace/provider_id in
  credential_owner_id and managed_secret_name
- Updated all credential runtime calls to pass workspace/provider_id
- Updated tests to use the new signatures

This prevents two workspaces sharing the same external credential store from
colliding on provider names, which was a critical security issue (CWE-639).

* fix(credentials): preserve provider-level expiration for handle-backed credentials

Compute effective expiration from both provider and driver values using the
earliest non-zero timestamp and skip expired values before insertion
(GATOR-1806c9be-02).

- Modified resolve_provider_handles to check provider credential_expires_at_ms
- Skip expired credentials during resolution instead of returning them
- Use effective expiration (min of provider and driver) in resolution results
- Fix inference.rs to preserve earliest expiration when merging

This ensures handle-backed credentials respect the same expiration semantics
as inline credentials.

* fix(credentials): stage refresh changes under new handles before validation

Stage credential replacements under new immutable handles instead of reusing
existing handles to prevent overwriting committed values before validation/CAS
(GATOR-1806c9be-03).

- Stage credentials with empty existing_handles map to force new handle creation
- Validate and CAS before the new values are committed to backend storage
- Delete old handles only after successful CAS
- On CAS failure, delete only the newly staged handles
- This prevents CWE-362/CWE-367 race conditions where failed refreshes could
  still modify or delete the active credential

The fix ensures that a rejected refresh cannot modify the backend object still
referenced by the committed provider record.

* fix(credentials): add timeouts to credential driver RPCs

Apply configured timeouts to both startup capability negotiation and runtime
RPCs to prevent indefinite hangs (GATOR-1806c9be-05).

- Add DEFAULT_CREDENTIAL_DRIVER_RPC_TIMEOUT_SECS constant (30s)
- Apply timeout to GetCapabilities during startup connection
- Apply timeout to all runtime RPCs (store, delete, resolve)
- Use tokio::time::timeout to bound the entire GetCapabilities operation
  during startup, not just the socket connection
- Return contextual deadline errors on timeout

This prevents a faulty or overloaded driver from hanging gateway operations
indefinitely.

* fix(credentials): fix test to use consistent workspace/provider identity

The Kubernetes auth Vault resolve test was constructing a managed path with
test-workspace/test-provider-id but sending default/prov-123 in the request,
causing validation to reject the request (GATOR-18e32351-01).

- Update test to use test-workspace and test-provider-id in the request to
  match the logical_path construction
- This ensures the test exercises the intended code path and validates
  Kubernetes auth resolution properly

The test now passes and correctly validates identity enforcement.

* fix(credentials): use unique staging ID for refresh to avoid overwrites

Stage refresh replacements under genuinely distinct immutable handles using
a unique staging ID to prevent overwriting committed values (GATOR-1806c9be-03).

- Generate a unique staging ID using UUID for each refresh operation
- Use this staging ID when storing credentials instead of the real provider ID
- Pass the same staging ID during cleanup on failure to delete only staged objects
- This ensures deterministic paths (Vault) and object names (K8s) don't collide
  with the committed provider's credentials

The fix prevents failed refreshes from silently replacing active credentials
or breaking providers by deleting still-referenced backend objects.

* fix(credentials): wrap credential driver RPCs in local timeouts

Add local tokio::time::timeout wrappers around credential driver RPCs to
bound non-compliant or stalled UDS peers (GATOR-1806c9be-05).

- Wrap StoreCredential, DeleteCredential, and ResolveCredentials in local timeouts
- Return contextual deadline_exceeded errors when timeouts occur
- Keep existing gRPC timeout metadata for compliant implementations
- GetCapabilities during startup was already wrapped in previous commit

This ensures a faulty local driver cannot hang gateway operations indefinitely,
even if it accepts the connection but never responds to the RPC.

Huabing (Robin) Zhao abcd15d1f2 feat(helm): add TLS termination for Envoy Gateway ingress (#2015)
The chart's optional Gateway API ingress only rendered a plaintext HTTP
listener, so the gateway could not be exposed over TLS. Add an HTTPS
listener option that terminates TLS at the Envoy Gateway and forwards
plaintext gRPC to the gateway pod.

- gateway.yaml renders an HTTPS listener with `tls.mode: Terminate` and
  `certificateRefs` when `grpcRoute.gateway.listener.protocol=HTTPS`,
  keeping the default HTTP listener unchanged. Guards fail the render when
  `certificateRefs` is empty or `server.disableTls` is not true (the chart
  does not render a BackendTLSPolicy for re-encryption).
- values.yaml adds `grpcRoute.gateway.listener.tls.certificateRefs`.
- ci/values-gateway-tls.yaml exercises the HTTPS branch in lint/render.
- docs/kubernetes/ingress.mdx documents HTTPS setup and clarifies that
  Envoy Gateway only terminates TLS (no OIDC SecurityPolicy); client
  identity uses OIDC bearer tokens, with the client-credentials grant for
  headless agents.
- debug-openshell-cluster skill gains HTTPS-ingress troubleshooting rows.
- Regenerated the chart README values table.

Taylor Mutch 5f58cb018f fix(helm): create sandbox JWT secret when cert-manager is enabled (#1700)
* fix(helm): create sandbox JWT secret under cert-manager

The cert-manager install path (certManager.enabled=true,
pkiInitJob.enabled=false) left the gateway StatefulSet unable to start
because nothing created the openshell-jwt-keys Secret: cert-manager owns
TLS Secrets but does not mint the sandbox JWT signing key, and the
certgen hook only rendered when pkiInitJob.enabled was true.

Separate JWT signing-key provisioning from TLS PKI provisioning:

- certgen: add a --jwt-only mode that creates only the Opaque JWT
  signing Secret, for use when another controller owns TLS Secrets.
- certgen.yaml: render the hook when pkiInitJob.enabled OR
  certManager.enabled is true. cert-manager takes precedence and runs
  the hook with --jwt-only even if pkiInitJob.enabled remains true.
  Remove the mutual-exclusion failure between the two values.
- _helpers.tpl: add openshell.sandboxJwtSecretName, shared by the hook
  and the StatefulSet mount.
- Update values, README, docs, architecture, and the
  debug-openshell-cluster skill to reflect the new precedence; the
  documented cert-manager install no longer needs pkiInitJob.enabled=false.

Closes #1691

* fix(helm): honor cert-manager precedence for client CA volume

The client CA volume logic treated pkiInitJob.enabled as proof that
built-in PKI owns the client CA. With cert-manager precedence now
allowing certManager.enabled=true alongside the default
pkiInitJob.enabled=true, that assumption mounts the server TLS cert
secret as the client CA and ignores
certManager.clientCaFromServerTlsSecret=false, which can break mTLS or
trust the wrong CA.

Gate the pkiInitJob.enabled term with (not certManager.enabled) in all
three client CA conditions (volume mount, volume definition, and secret
selection) so cert-manager owns TLS when enabled. Add a Helm test suite
covering built-in PKI, cert-manager shared CA, the regression config
(cert-manager + clientCaFromServerTlsSecret=false + default pkiInitJob),
and the no-client-CA case.

Seth Jennings c94cddbfb8 feat(server): separate HTTPS from mTLS authentication (#1351)
Make --tls-client-ca optional and make client certificates always
optional when a CA is configured. This decouples HTTPS encryption
from mTLS authentication, allowing mTLS and OIDC bearer tokens to
coexist as parallel authentication mechanisms.

When --tls-client-ca is provided, client certificates are validated
against the CA when presented but never required. Clients may connect
with or without a certificate — authentication is handled at the
application layer (e.g. OIDC).

Two TLS modes are now supported:
- HTTPS with optional mTLS (--tls-client-ca provided)
- HTTPS-only (--tls-client-ca omitted)

The --disable-gateway-auth flag is preserved for backward
compatibility but is now a no-op. The allow_unauthenticated field
has been removed from TlsConfig. The Helm chart conditionally
includes the client-ca volume and env var based on whether
clientCaSecretName is configured.
