[review-stack 3/4] tests-changed — synap5e/feat/asset-record-content-split

[synap5e]

Layer 3/4 of the review-and-land stack for synap5e/feat/asset-record-content-split, generated by
review-stack.py. Full collapse procedure: ~/adocs/review-stack.md. Once the
stack starts collapsing, don't rerun build/push on it — a rebuild resets every
layer to its original scope from the untouched source branch and discards the collapse.

Once approved, merge this into #15916 (ordinary "Merge" — fast-forward). Once everything above has merged down into this one and it's approved, continue the collapse toward layer 1.

Rule: remaining modified test files (incl. conftest.py / helpers)
Question for this layer: Did the edits weaken an existing check?

Stack:

1. [review-stack 1/4] code — synap5e/feat/asset-record-content-split #15915 code — Is the logic change right?
2. [review-stack 2/4] tests-removed — synap5e/feat/asset-record-content-split #15916 tests-removed — For each dropped assertion: obsolete by a ruling, or covered by a tests-new test?
3. [review-stack 3/4] tests-changed — synap5e/feat/asset-record-content-split #15917 tests-changed — Did the edits weaken an existing check?
4. [review-stack 4/4] tests-new — synap5e/feat/asset-record-content-split #15918 tests-new — Is the code layer well covered?
