- Wire the documented record_dataset option: new widget on the AutoTuner
node calls _save_tuner_dataset_entry after each full sweep (the
function existed, was tested, and was documented in the wiki — but
nothing ever called it). Wiki wording aligned: entries are recorded
on full sweeps only, cache/memory replays don't append.
- Merge-on-write for shared cache files: lora/pair/analysis cache saves
and the content-hash cache re-read the on-disk state and overlay the
caller's keys (caller wins; None never clobbers a real lora entry;
analysis entries are remapped to the caller's stack order first).
Entries are content-derived so same-key collisions hold equivalent
data — this removes cross-process lost updates without resorting to
cross-platform file locking. The GC's prune save passes merge=False
so dead keys aren't resurrected.
- Model/clip identity tracking via weakrefs (_track_model_identity):
bare id() comparison could alias a new object reusing a freed
object's address and serve a stale cached merge; the guard now also
detects clip swaps and id reuse. Shared by optimize_merge and
auto_tune.
- _extract_block_name is lru_cached (pure function, called per prefix
per smoothing pass with two regex evaluations) and drops its local
re import.
Adds 3 test classes (235 total pass).
