authzConfigMap.nameand the release namespace as configuration. This creates a security gap and a silent misconfiguration path from one root cause.

getEntitiesinserts onecedar.EntityMapper distinctuserstring and never evicts on age or size.EntityCachewraps async.Map, so entries persist untilInvalidateorInvalidateAllruns. Both run only on watch events fromStartWatching.Two consequences follow. First, memory grows with the number of distinct authenticated subjects seen since process start, including service accounts and rotated identities that never return. Second, if the watch channels close (see
StartWatchinginplatform-api/pkg/authz/reload.go, which returns on!ok), invalidation stops permanently and every cached entity map is served stale for the process lifetime. Stale entity maps mean revoked role bindings still grant access.Add a TTL to each cache entry, and add a maximum entry count with eviction. A TTL also bounds the blast radius when watch-driven invalidation stops.

StartWatching returns an error that is discarded, so policy hot reload can fail silently.
StartWatching (platform-api/pkg/authz/reload.go line 19) returns error. It opens four watches and returns early if any Watch call fails, after stopping the watches it already opened. Line 226 discards that error.
StartWatching also does not block. It starts its own two goroutines and returns, so the go keyword adds nothing except the loss of the error value.
If a watch fails, the process starts and serves traffic with a policy set frozen at startup and an entity cache that is never invalidated. A deleted RoleBinding continues to grant access for the process lifetime, with no log line and no failed probe. This defeats the revocation path that the rest of this PR builds.
Call StartWatching directly and handle the error.

Cedar binds && tighter than ||, so a condition with a top-level ||, for example true || true, makes the whole clause always true and defeats the namespace pinning.

Provide a secure first RoleBinding path.
The reconciler now accepts only Roles, and every supplied configuration creates only Roles. A fresh deployment therefore starts with no authorized principal. The test plan states that users without bindings receive 403 responses for all requests. No user can create the first public RoleBinding through the authorized API.
Add a deployment-specific bootstrap mechanism. Require the installer to provide the bootstrap subject. Do not restore a hard-coded employee identity. If an external provisioning flow creates the first binding, implement and document that flow before enabling authorization.

Inline comments:
In `@deploy/kind/README.md`:
- Around line 166-178: Create my-cluster and other-cluster in org-1 before the
user1 GET and list requests, using an authorized identity and the existing
resource-creation workflow; alternatively, update those requests to reference
resources already created by the workflow while preserving the expected 200,
403, and filtered-list outcomes.
- Around line 125-136: Remove or relocate the unconditional cluster-ro binding
for user1@example.com before the conditional-binding test, or change it to use a
different subject, so user1@example.com has no prior unconditional grant when
validating the other-cluster 403 and filtered-list behavior.
- Around line 277-280: Update the org-2 cluster listing example after kubectl
apply to wait for the asynchronous policy reload before asserting success. Add a
bounded retry loop or readiness check around the curl using alice’s user info,
preserving the expected eventual HTTP 200 while avoiding transient 403 failures.
- Line 100: Update both userinfo() definitions to remove Base64-generated
newline characters as well as padding characters before returning the encoded
value, preserving the existing JSON payload and URL-safe character translation.
- Around line 199-210: Update the documentation around userinfo() and the
adjacent X-Endpoint-API-UserInfo tests to mark them as local-only because the
Kind NodePort bypasses ESPv2 and does not authenticate the header. State that
production traffic must pass through a trusted proxy that authenticates
identity, injects the header, and strips any client-supplied header.
In `@platform-api/api/private/v1/rolebinding_types.go`:
- Around line 32-51: Update GeneratePolicies to index and select bindings by
RoleRef kind, namespace, and name, including only RoleRefKindRole bindings whose
namespace matches the Role being processed. Prevent PlatformRole bindings or
same-named roles from other namespaces from being included, and add collision
tests covering both namespace and role-kind differences.
In `@platform-api/api/private/v1/rolebinding_validator.go`:
- Around line 32-53: The condition validation currently runs during
ValidateDelete and uses a fragile strings.Contains deny-list. Move
validateBindingCondition into validateRoleBinding for create/update validation,
and make ValidateDelete return without checking the stored condition. Replace
the namespace deny-list with allow-list validation that preserves rejection of
direct namespace entity references, and update GeneratePolicies to combine the
base condition with the parenthesized binding condition using a logical AND so
false || true cannot bypass the guard. Add regression coverage for invalid
create/update conditions and the false || true case.
In `@platform-api/api/public/v1/.schemas/platformrole_schema.yaml`:
- Around line 23-33: Update the public PlatformRole authorization configuration
to explicitly deny POST, PUT, PATCH, and DELETE requests before they reach
ConvertingResourceHandler, then add endpoint-level regression tests covering
each method and confirming the write is rejected without modifying the private
store.
In `@platform-api/pkg/authz/middleware.go`:
- Around line 211-247: Update both JSON conversion paths to use json.Decoder
with UseNumber, and change anyToCedar to parse json.Number only as an exact,
range-checked integer before creating cedar.Long; preserve fractional and
out-of-range values without truncation or overflow. Replace the nil and
unsupported-type fallbacks in anyToCedar with rejection/error propagation, and
apply the same behavior through mapToCedarRecord so invalid authorization
attributes cannot become empty strings.
- Around line 153-177: Update the request-body handling in buildCedarContext to
read through a bounded reader, detect oversized payloads, and return read errors
instead of discarding them or using partial bytes. Propagate the error to the
middleware caller, which must respond with HTTP 413 for body-limit violations
and reject other read failures; preserve body restoration only for successfully
read, permitted payloads.
In `@platform-api/pkg/authz/policygen.go`:
- Around line 22-25: Update the policy generation flow around bindingsByRole to
index bindings by RoleRef.Kind, namespace, and role name, and match each
generated policy only to its referenced role entity. Ensure Role and
PlatformRole references with identical names, including across namespaces,
remain distinct, and add coverage for cross-role, cross-kind, and same-name
bindings.

Strip wrapped Base64 newlines from the header value.
The helper removes = but not line breaks. GNU base64 wraps output at 76 characters, so userinfo stranger@example.com produces an internal newline. curl can reject that header, and the unknown user -> 403 check may never reach the API. Strip \n and = in both userinfo() definitions.

Remove the unconditional binding before testing the condition.
The sequence grants user1@example.com the unconditioned cluster-ro Role at Line 125. The later binding adds a condition for the same subject and Role. In an allow-based binding model, the earlier grant already permits all cluster-ro access, so the other-cluster -> 403 and filtered-list checks do not validate the condition. Use a different subject for the unconditioned example, or remove it before this test.

Create the test resources before asserting these responses.
The workflow does not create my-cluster or other-cluster in org-1. The only cluster creation shown is test in org-2 at Lines 238-243. A clean run cannot return 200 for GET .../my-cluster; it can return 404 before authorization is evaluated.

kubectl apply updates the binding, but the watch-driven Cedar reload runs asynchronously. The next curl can race the reload and return a transient 403. Add a bounded retry loop or a readiness check before treating 200 as the expected result.

Cedar policy language official documentation operator precedence for && and ||
💡 Result:
In the Cedar policy language, the logical AND (&&) operator has higher precedence than the logical OR (||) operator [1]. According to the official Cedar grammar, expressions involving these operators are structured as follows [1]: 1. The And expression is defined as a sequence of Relation expressions joined by && [1]. 2. The Or expression is defined as a sequence of And expressions joined by || [1]. This structure ensures that && is evaluated before || when both are present in an expression [1]. Consequently, an expression like A || B && C is evaluated as A || (B && C). Both operators support short-circuit evaluation [2][3]. For &&, if the first operand is false, the entire expression evaluates to false and the second operand is not evaluated [2]. For ||, if the first operand is true, the expression evaluates to true and the second operand is not evaluated [2].

Validate conditions at write time and preserve the namespace guard.
Call validateBindingCondition from validateRoleBinding, and let ValidateDelete return without validating the stored condition. Replace the strings.Contains deny-list with allow-list-based validation. In GeneratePolicies, wrap the condition as baseCondition + " && (" + rb.Spec.Condition + ")"; otherwise false || true makes the complete guard evaluate to true. Add regression tests for invalid create/update conditions and false || true.

The condition validation currently runs during ValidateDelete and uses a fragile
strings.Contains deny-list. Move validateBindingCondition into
validateRoleBinding for create/update validation, and make ValidateDelete return
without checking the stored condition. Replace the namespace deny-list with
allow-list validation that preserves rejection of direct namespace entity
references, and update GeneratePolicies to combine the base condition with the
parenthesized binding condition using a logical AND so false || true cannot
bypass the guard. Add regression coverage for invalid create/update conditions
and the false || true case.

Limit request-body reads and handle read errors. platform-api/pkg/authz/middleware.go:157 calls io.ReadAll(r.Body) without a limit. An authenticated client can cause excessive memory allocation. The code also discards read errors and restores partial bytes to r.Body. Limit the read, return the error from buildCedarContext, respond with 413 for oversized bodies, and reject other read failures.

Preserve integer values used for authorization.
json.Unmarshal converts JSON numbers to float64, and anyToCedar converts every number to int64. This truncates fractions, rounds values above 2^53, and converts math.MaxInt64 to math.MinInt64. A Cedar condition can therefore authorize a different value than the request or stored object.
Use json.Decoder.UseNumber in both conversion paths. Parse only exact, range-checked integers. Reject unsupported values instead of converting them to an empty string.

Add new API resource types for Cedar-based authorization: - PlatformRole: cluster-scoped role with permissions (system-managed) - Role: namespace-scoped role with permissions (user-defined) - RoleBinding: binds subjects to roles with optional Cedar conditions Includes validators, schemas, and generated code (deepcopy, conversion).
Add authentication middleware to extract and validate user identity from request headers (X-Forwarded-User, X-Forwarded-Email). Includes context utilities and comprehensive unit tests.
Implement Cedar policy engine integration for fine-grained authorization: - Authorizer with Cedar policy evaluation - Entity conversion (resources, principals, actions) - Policy generation from PlatformRoles, Roles, and RoleBindings - Authorization middleware with request interception - Policy cache with automatic reload from storage - Permission definitions for all API operations Includes comprehensive unit tests for all components.
Enhance Orlop framework to support authorization: - Add context utilities for extracting user identity and namespace - Propagate context through handler chain - Add namespace-based filtering to storage backends (memory, postgres, spanner) - Update router to accept middleware functions - Add middleware support to server configuration These changes enable per-request authorization checks and namespace-scoped resource isolation.
Wire up authentication and authorization to platform-api-server: - Register PlatformRole, Role, and RoleBinding resources - Initialize Cedar authorizer with policy cache - Add authn and authz middleware to request pipeline - Start background policy reload goroutine - Add Cedar dependency to go.mod This enables fine-grained access control for all API operations.
Add system-managed PlatformRole templates: - cluster-admin: full cluster access (all permissions) - cluster-viewer: read-only cluster access - service-admin: full access within namespaces These roles are deployed via Helm and loaded through the private API. Add authz configuration to values.yaml with reload interval.
Add local development deployment support: - Kind cluster setup script with oauth2-proxy for authn - Kustomization overlays for Kind environment - NodePort service for external access - ClusterIssuer for TLS certificates - Teardown script for cleanup - Containerfile for building controller images Enables local testing of the full authz stack.
Add comprehensive documentation for Cedar-based authz: - Developer guide: architecture, entity model, policy generation - Test plan: functional and security test scenarios - User-defined roles guide: creating custom roles and bindings Covers both operator and end-user perspectives.
Update controller manager to register Cedar authorization types: - Add PlatformRole, Role, and RoleBinding to scheme - Update dependencies for Cedar support Enables controllers to watch and reconcile authz resources.
