Summary

New PictureTestsBase conformance suite (18 tests) for the sense picture methods of IMiniLcmApi, run against CRDT and FwData. Previously pictures were only covered by three sync tests; MovePicture and GetPicture had no direct tests.

The suite showed the two implementations disagreed on GetPicture with the wrong parent. Both now match the example sentence contract:

GetPicture called with	CRDT before	FwData before	Both now
wrong sense	null	throws	ParentMismatchException
missing sense	null	throws	ParentMismatchException
wrong entry	returns picture	returns picture	ParentMismatchException

 CrdtPictureApi.GetPicture
   sense = repo.GetSense(senseId)
-  return sense?.Pictures.Find(id)
+  if sense: VerifySenseBelongsToEntry; return owned picture if found
+  ownerSenseId = repo.GetPictureSenseId(id)   # only when not in the named sense
+  null -> return null, else throw ParentMismatchException

 FwDataMiniLcmApi.ValidateOwnership(ICmPicture)   # shared by Get/Update/Move/Delete
   check sense
+  check entry

GetPictureSenseId SQL (pictures are jsonb on the sense row, so this scans senses):

SELECT [s].[Id] FROM [Sense] [s]
WHERE EXISTS(SELECT * FROM [json_each]([s].[Pictures]) [p] WHERE [p].[value]->>'Id' = @id)
LIMIT 1

Known disagreement, left as-is: inserting/moving with only Previous set when an item follows it. FwData inserts right after Previous; CRDT's OrderPicker picks Previous.Order + 1, which ties with the next item and is broken by GUID (documented as accepted; same for senses/examples; sync always passes both neighbours). The previous-only test uses the last picture so it's well defined.

Not covered: CRDT SubmitUpdatePicture/MovePicture/DeletePicture still don't validate parents (sync relies on them being forgiving).

Merge Danger

Door: two-way

Blast Radius: narrow

GetPicture and FwData picture update/move/delete now throw for a mismatched entry/sense where they previously returned a result or silently acted. Sync always passes the real parents; picture sync tests pass.

Test plan

• LcmCrdt.Tests MiniLcmTests.PictureTests: 18/18 (before the fix: 15/18, the three wrong-parent Get tests failed)
• FwDataMiniLcmBridge.Tests MiniLcmTests.PictureTests: 18/18 (before the fix: 17/18, wrong-entry Get failed)
• FwLiteProjectSync.Tests filtered to Picture: 10/10

Walkthrough

The picture APIs now check whether a picture belongs to the requested entry and sense. The CRDT repository can find the sense that owns a picture. Shared tests cover picture retrieval, creation, insertion, updates, moves, deletion, and ownership errors. Test fixtures run the shared tests against the CRDT and bridge APIs.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to 4e40d

Picture ownership checks are now consistent across both backends. One edge case remains in the CRDT backend: a picture create or update sent with the wrong entry ID saves the change and then reports an error. Normal sync does not appear to trigger this. The fix is small and should be addressed soon, but the change is otherwise mergeable.

_{A rabbit checks each picture’s place,
Then hops through tests at a steady pace.
It adds a caption, moves one along,
And checks that ownership stays strong.
With ears held high, it marks the end,
Then shares a carrot with a friend.}
