Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔴 Critical · up to This PR adds authorization enforcement and persistence, but the current head is not merge-ready: protected database creation and authorization operations can fail or crash, concurrent permission changes can overwrite one another, revocation can leave invalid permission documents, and the new tests do not compile or pass as written.

Inline comments:
In `@src/atomdb/AtomDBFactory.cc`:
- Around line 115-123: The protected AtomDB path currently constructs
AuthorizationManagement with null persistence, causing creation to throw; update
wrap_if_protected() and AuthorizationManagement so the manager is either built
with a real MongoAuthorizationPersistence or safely denies all authorization
requests when persistence is unavailable, preserving fail-closed behavior and
eliminating the null-construction failure.
In `@src/atomdb/auth/AuthorizationManagement.h`:
- Around line 70-75: Add an api_mutex member to AuthorizationManagement and
guard all manifest reads and writes in is_authorized(), authorize(), revoke(),
and revoke_all() with lock_guard<mutex> semaphore(this->api_mutex); keep the
critical sections limited to manifest access and avoid holding the mutex during
persistence I/O where ordering permits.
- Around line 17-32: Align AuthorizationManagement’s constructor declaration and
its authorization_test.cc callers so they use the same argument count,
preserving the existing AuthorizationPersistence dependency and ensuring the
authorization test compiles.
In `@src/atomdb/auth/AuthorizationManifest.cc`:
- Around line 54-57: Update the removal logic in
src/atomdb/auth/AuthorizationManifest.cc:54-57 to remove the entire manifest
document when deleting the final entry. Update the corresponding persistence
logic in src/atomdb/auth/MongoAuthorizationPersistence.cc:93-112 to delete the
MongoDB document in that case. Adjust
src/tests/cpp/authorization_test.cc:100-102 to expect the key to be
unregistered, and src/tests/cpp/redis_mongodb_test.cc:1529-1532 to expect no
permission document after final-entry revocation.
In `@src/atomdb/auth/BUILD`:
- Around line 39-52: Update src/atomdb/auth/BUILD lines 39-52 to make
authorization_management depend on authorization_persistence instead of
mongo_authorization_persistence; update src/atomdb/BUILD line 93 so
protected_atomdb depends on authorization_management instead of auth_lib; then
verify src/tests/cpp/BUILD lines 871-888 for authorization_test and, only if
required, add the mongocxx and bsoncxx linkopts used by redis_mongodb_test.
Apply the same fix in `@src/atomdb/BUILD` at line 93.
In `@src/tests/cpp/authorization_test.cc`:
- Around line 54-58: Update the authorization tests to match current interfaces:
in src/tests/cpp/authorization_test.cc lines 54-58, change
FakePersistence::remove to accept const AccessPermissionEntry&; in lines 90-102,
replace entries() with the supported manifest API and pass each entry to
remove(); in src/tests/cpp/redis_mongodb_test.cc lines 1513-1532, use access_key
instead of public_key and pass the entry to
MongoAuthorizationPersistence::remove().
In `@src/tests/cpp/redis_mongodb_test.cc`:
- Around line 1507-1511: Update the assertion for public_key in the MongoDB
persistence test around collection.find_one so it verifies the field is present
rather than absent, while preserving the existing _id and full_access
assertions.

Inline comments:
In `@src/atomdb/auth/AuthorizationManager.cc`:
- Around line 9-10: Update AuthorizationManager::AuthorizationManager to
validate persistence before storing it and raise the existing error type via
RAISE_ERROR when it is null. Adjust the authorization test so it expects
AuthorizationManager construction with a null persistence to throw
runtime_error, rather than invoking a public operation afterward.
- Around line 2-4: Add the file-level standard namespace directive alongside the
existing atomdb namespace directive in AuthorizationManager.cc, and add it
alongside the existing domain namespace directives in
MongoAuthorizationPersistence.cc. Ensure both source files explicitly declare
std rather than relying on an included header.
Apply the same fix in `@src/atomdb/auth/AuthorizationManifest.cc` at line 9: The
same file-level namespace declaration is required here.
In `@src/atomdb/auth/ManifestAuthorizer.cc`:
- Around line 16-17: Update ManifestAuthorizer::ManifestAuthorizer to reject a
null manifest during construction by applying the established RAISE_ERROR
mechanism for fatal invariant violations; keep valid manifest initialization
unchanged and prevent either is_authorized overload from being reachable with a
null manifest.
In `@src/atomdb/auth/MongoAuthorizationPersistence.cc`:
- Around line 1-8: Configure logging in MongoAuthorizationPersistence.cc by
defining LOG_LEVEL to the appropriate INFO_LEVEL or DEBUG_LEVEL before directly
including Logger.h, so the existing LOG_DEBUG usage has the required local
logging configuration.
- Around line 62-105: Update save to prevent concurrent authorization updates
from overwriting one another: replace the read-and-replace flow around
get_document and replace_one with an atomic MongoDB update pipeline, or use a
revision field in the replacement filter with retries on revision conflicts.
Preserve grant and revoke behavior, and add a behavior-focused concurrent
grant/revoke regression test covering both updates.
- Around line 49-55: Update MongoAuthorizationPersistence::list to check whether
get_document returns nullptr before accessing document->entries; return an empty
list for an unregistered public_key and preserve the existing entries result for
registered keys.
In `@src/atomdb/ProtectedAtomDB.cc`:
- Around line 16-18: Complete ManifestAuthorizer injection in ProtectedAtomDB:
update the constructor declaration in src/atomdb/ProtectedAtomDB.h at lines
167-167 to accept the required authorizer, and update its definition in
src/atomdb/ProtectedAtomDB.cc at lines 16-18 to store and validate a non-null
value in auth.
In `@src/tests/cpp/authorization_test.cc`:
- Around line 98-113: Update the authorization test around manifest.get_document
and entries so the entries collection is obtained after manifest.add and bound
by reference to the document’s current entries, rather than copied before the
mutation. Keep the existing assertions and removal behavior unchanged while
ensuring they inspect the updated manifest state.

Prevent concurrent permission updates from overwriting each other.
save reads the complete document and replaces it using a filter with only _id. If two requests read the same document, each request can write a different replacement. The later write removes the earlier grant or revocation.
Use an atomic MongoDB update pipeline, or add a revision field to the replacement filter and retry on a revision conflict. Add a concurrent grant/revoke regression test.
As per path instructions, thread safety and behavior-focused tests are required for authorization persistence changes.

This PR introduces the core authorization components:
AuthorizationManifest– in-memory store for permission documents and entriesManifestAuthorizer– checks READ/WRITE access against the manifest using schema matchingAuthorizationManager– high-level API for granting, revoking, and listing permissionsMongoAuthorizationPersistence– MongoDB-backed persistence implementationAlso includes unit tests covering the main authorization flows.
