Wait for the free limit to reset to keep reviewing this public repository. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Included review availability: Your plan includes up to 1 review per rolling hour; 0 remain after this review. 📝 WalkthroughWalkthroughThe pull request adds in-memory MongoDB integration tests for eight DAOs. It updates DAO exports, documents function contracts, removes obsolete helpers, and standardizes missing-record errors in group, scenario, and user operations. ChangesDAO validation and contracts
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR adds DAO tests and adjusts DAO behavior, but updating a missing scenario still produces a non-standard error instead of the expected 404 response, which can cause inconsistent client-facing error handling. Merge should wait for this behavior to be corrected or explicitly accepted. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

In `@backend/src/db/daos/__tests__/accessDao.test.js`:
- Around line 47-56: Update the test “grants and revokes access entries without
duplicating emails” to call grantAccess for “alice@example.com” twice, then
assert that the resulting accessList contains that email exactly once while
preserving the existing entries.
In `@backend/src/db/daos/__tests__/groupDao.test.js`:
- Around line 35-39: Update the missing-record assertions in
backend/src/db/daos/__tests__/groupDao.test.js lines 35-39 and
backend/src/db/daos/__tests__/userDao.test.js lines 89-95 to verify the rejected
error has status 404 and the exact messages “group not found” and “user not
found,” respectively, while retaining the HttpError type check.
In `@backend/src/db/daos/__tests__/noteDao.test.js`:
- Around line 48-50: Update the test around hasNoteInGroup to reload the Group
after createNote, then pass the refreshed document to hasNoteInGroup and assert
that the note reference exists.
In `@backend/src/db/daos/__tests__/sceneDao.test.js`:
- Around line 181-208: The test around createScene must use an existing source
scenario so it specifically validates rejecting a direct link to a scene from
another scenario. Create a source Scenario containing a local scene, then pass
that scenario’s ID to createScene while retaining otherScene as directLink; keep
the expected 400 rejection.
In `@backend/src/db/daos/scenarioDao.js`:
- Line 171: Update updateScenario to detect a null result from Scenario.findById
and route it through the shared missing-scenario handler, returning
HttpError("scenario not found", 404) consistently with other scenario mutation
functions. Add a missing-record test for updateScenario that verifies a valid
but absent scenarioId produces status 404.
In `@backend/src/db/daos/sceneDao.js`:
- Around line 20-29: Update hasFileRef so it always returns a boolean, coercing
the component.fileId condition to true/false while preserving the existing
audio/image type check and false result for missing components.
- Line 257: Update incrementVisisted to increment the visited field atomically
with MongoDB’s $inc operation, avoiding any read-modify-write sequence for the
same sceneId. Add a concurrent integration test that verifies all increments are
preserved when multiple calls target one scene.
- Line 126: Update createScene to validate that scenarioId exists when
directLink is null, rejecting unknown parents before persisting the scene.
Increment references for image and audio file components, and make scene
persistence, scenario association, and file-reference updates atomic or
compensating; add coverage for an unknown scenarioId and a created scene
containing a file component.
- Line 286: Update updateSceneOrder to load the scenario’s current scene IDs and
validate that sceneIds is an exact permutation: require matching length, reject
foreign or nonexistent IDs, and reject duplicates before replacing
Scenario.scenes. Preserve the existing update behavior for valid reordered
lists, and add a test covering a same-length list containing a foreign ID.

In `@backend/src/db/daos/sceneDao.js`:
- Around line 324-342: Add the validated scene snapshot as scenes:
scenario.scenes in the findOneAndUpdate filter, alongside scenarioId, and return
null when no document matches so concurrent scene changes produce a conflict
rather than being overwritten.
- Around line 156-172: Update the rollback logic in the scene-creation catch
path and its associated Scenario.updateOne/applyReferenceDeltas flow so inverse
file-reference deltas are applied only when the forward scenario update and
reference operation actually succeeded. Handle matchedCount === 0 and partial
unordered bulkWrite failures without compensating operations that were never
committed, using a transaction or explicit success tracking.

@leowla i've just removed the rollback logic entirely. it was a bad solution, and there's no point finaggling with that when the best solution is clearly to use transactions. will make a ticket for that now. |

here and many other places seem like a good place to have your new getScenarioOrThrow

idk mongoose but claude says it User.create will init the assigned field with a blank array instead of actually being empty which is not expected behaviour in this test

damn i told claude code to make no mistakes 😞 |

Issue
Much of the dao logic was completely untested.
Solution
Added many unit tests for a large percentage of dao logic.
Risk
Funcionality of some daos was slightly modified as tests revealed issues, but no changes are logic changes.
