+
+## False Positives — Edge Cases (5)
+
+Investigated and determined to be correct behavior or non-issues.
+
+| Issue | Verdict |
+|-------|---------|
+| E2: `EditGraph.getHead()` returns undefined vs null | **Correct** — `undefined` is standard TS for "not present"; all callers use `!head` which handles both |
+| E3: First commit creates self-referential branch | **Intentional** — `branches: { main: nodeID }` is standard DAG initialization; "main" → first node is correct |
+| E4: `Objective.extract()` concurrent race | **False positive** — prompt loop serializes calls per session; concurrency cannot occur |
+| E5: `SideThread.create()` duplicate ID not caught | **Correct** — `Identifier.ascending()` is unique (timestamp+counter+random); DB error on collision is the right behavior (fail loudly) |
+| E6: SHA-256 collision in CAS not detected | **Intentional** — SHA-256 has no known collisions; `onConflictDoNothing()` was explicitly chosen (B43 fix) |
+
