A self-contained prompt for a fresh session to finish the last 10 files over the 250-line cap, all Dart. It carries the parts that are expensive to rediscover: - scripts/split_dart_test.py, which works, plus the envelope it works in: one pass from the pristine file, no post-main() declarations, no local function declarations in the preamble. All four remaining test files sit outside that envelope, and the fix (hoist shared fakes into a _fixtures.dart sibling first, as its own commit) is written down. - The three Dart constraints each of which cost a debugging cycle here: setState is @protected so it cannot be called from an extension; extension methods dispatch statically so a method a test fake overrides must stay in the class (this hung four tests on pumpAndSettle rather than failing an assertion); static members need qualifying inside an extension. - 402 as the test-count invariant, and the note that dart analyze is a no-op on test/ so the count is the only signal there. - That the local gatelock (0.5.0) is ahead of the pin (0.4.0), so the popup gate's failure here is environment drift and must NOT be "fixed" in code.

"""Split a Dart test file at top-level `group(` boundaries.
|
|
|
|
Each output file reuses the original's imports and its main() setup preamble
|
|
(everything between `void main() {` and the first top-level group), so every
|
|
part runs the same fixtures the original did.
|
|
|
|
Usage:
|
|
split_dart_test.py <file> <out1>:<firstGroupIdx> [<out2>:<idx> ...]
|
|
|
|
Indices are 0-based positions in the top-level group list; each output takes
|
|
groups[idx:next_idx]. The source file keeps groups[:first_idx].
