PERTAIN_TOProblem

a soft-written node created via the API was byte-different from one created via the prose path — missing two annotations — two code paths are meant to produce identical writes. Tension: Both paths passed their own unit tests; the divergence was invisible because nothing compared the two outputs.

PERTAIN_TOReport

Neo4j silently drops null-valued properties — 'k' IN keys(n) is false after CREATE (n {k: null})

PERTAIN_TORootCause

`CREATE (n {a: null}) RETURN keys(n)` returns `[]`. Tension: `keys(n)` never includes a null-valued property → `'k' IN keys(n)` is false. Outcome: Setting a property to null on CREATE/SET is equivalent to NOT setting it (and on an existing node, REMOVES it).

PERTAIN_TOSolution

Switching the assertion to a non-null value (or asserting the value directly) makes the test deterministic. Tension: It can't pass for the null case. Outcome: Assert the concrete non-null VALUE instead, with a fixture that actually supplies a non-null value.
