Removed the `.bak` backup file for policy tests that was accidentally left in the repository, as it is not needed for the project and should not be tracked. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The policy denial reason now accurately reflects when a policy is absent rather than incorrectly reporting a generic denial. This ensures that error messages provide the correct context for debugging and user feedback. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The JSON-RPC request parser now treats a null `params` field as equivalent to an absent one, defaulting to an empty array instead of failing validation. This aligns with the JSON-RPC 2.0 specification, which permits `params` to be omitted or null, and prevents spurious errors for clients that send explicit nulls.

The JSON-RPC response parser now correctly handles null values in the result field instead of treating them as missing or invalid.

…workspace The workspace root caching logic was changed to not store a fallback path when the workspace directory does not exist, preventing a later symlink from being masked by a stale cache entry. Additionally, the order of checks in path validation was adjusted so that a symlink pointing to a protected directory is diagnosed before the missing-workspace error, ensuring that a symlink escape is not incorrectly reported as a missing workspace. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The canonical workspace value is now retrieved in a single expression rather than being split across multiple lines, making the code more concise while preserving the same fallback behavior when the cached value is unavailable.

The test for protected root diagnosis now only checks for the "protected" error message, removing the alternative "escapes workspace" condition. This ensures the test specifically validates that protected roots are correctly identified as forbidden, rather than accepting a less specific workspace escape error.

…ectory creation Replace direct calls to `tokio::fs::create_dir_all` with a new `create_validated_parent_dirs` function that creates parent directories one component at a time within the workspace root. This prevents a removed workspace from being silently recreated by `create_dir_all` beneath a trusted ancestor, while preserving normal recursive creation for paths outside the workspace.

The test `domain_subscriber_registration_wrapper_defers_without_a_global_bus` was changed from a synchronous `#[test]` to an asynchronous `#[tokio::test]` and its function signature updated to `async fn`.

…lobal bus dependency Replace the async test that relied on the process-wide BUS singleton with a synchronous test using a local Mutex-based completion set. The original test could only verify the deferred path because unit tests never initialize the global bus, whereas the new test explicitly controls the ready state through `group_first_time_when_bus_ready`, making both the deferred and ready paths observable.

tokio::sync::OnceCell::set is asynchronous, so discarding its future leaves canonical_workspace empty. This makes the new cache assertions fail, and more importantly, when a symlinked workspace is removed after validation, create_validated_parent_dirs cannot recover the validated canonical root and falls through to create_dir_all(parent), recreating the workspace through its trusted ancestor—the exact case validated_symlink_workspace_is_not_recreated_through_trusted_ancestor is intended to prevent. Await the set call before reading the cell.
