ProjectKey fetches live API data, so it must re-execute on every queue.
Added comment explaining why source_label exists but is unused in Python.

The history_tree_backup (created by _delete_nodes) was storing full
snapshot data in every backed-up node — 185MB+ per backup entry.
This caused the JSON file to re-bloat to 300MB on every save.
Now:
- _delete_nodes backs up tree metadata only (no snapshot data)
- Load paths strip snapshot data from existing backup entries
- Prevents both disk and RAM bloat from backup accumulation

The JSON file was storing full snapshot data in every history node,
causing files to grow to multi-GB. Now when DB is enabled:
- sync_to_db receives full tree (extracts snapshots to DB)
- save_json receives slim tree (no snapshot data)
- JSON file stays small, DB is authoritative for snapshots
When DB is disabled, JSON still stores full snapshots (only store).

- Add load_json to tab_timeline_ng imports (NameError on disk fallback)
- Wrap save_history_tree in BEGIN/COMMIT transaction (was autocommitting
each statement, risking partial writes on failure)
- Clean up orphaned history_snapshots in sync_to_db when nodes are
removed from the tree

- _auto_change_note now loads previous snapshot from DB instead of
reading stripped in-memory node (was producing wrong commit messages)
- _render_mass_update now strips snapshots after save (was leaking RAM)
- Only strip snapshots when DB is enabled (preview/restore still works
without DB via in-memory or disk fallback)
- _render_data_preview adds disk fallback matching _restore_node

History tree nodes stored full data snapshots in memory (5-50MB each),
accumulating with every save. Now:
- New `history_snapshots` DB table stores node data separately
- `save_history_tree` and `sync_to_db` extract snapshots before saving
- In-memory tree nodes only hold metadata (id, parent, note, timestamp)
- Restore and preview load snapshots from DB on demand
- `save_and_snap` uses json roundtrip instead of deepcopy (1 copy not 2)
- `_src_cache` moved to AppState, cleared on file switch
- `strip_snapshots()` method on HistoryTree for explicit cleanup

json.dump in a background thread would crash with "dictionary changed
size during iteration" when the UI mutated data concurrently. Now all
save_json and sync_to_db calls receive a json.loads(json.dumps(data))
snapshot, isolating the serialization from live UI mutations.

Replaces slow JSON file parsing with fast DB queries for file loading.
Returns the same dict structure as load_json (top-level + batch_data +
history_tree).

- load_file and on_select try db.load_full_data first (~0.01s),
fall back to load_json only when DB has no data
- Fix unawaited coroutine warning for auto-load (asyncio.ensure_future)
- Fix radio on_change to properly await async load_file
- Reuse current data cache when source file matches current file,
eliminating a redundant 1.3s JSON parse during render

Runs at DB startup, only updates rows that have stale separate strength
keys. No-op once all data is migrated.

Combines separate lora name and strength keys into "name:strength" format,
removing 6 strength keys to free output slots for mode. Migration handles
legacy <lora:> wrapper, separate strength keys, and already-merged formats.

Adding all 33 DEFAULTS keys to sequences caused the ComfyUI loader
to exceed its 32 output slot limit, triggering tuple index out of
range errors. Only lora strength migration remains on load/sync.

Ensures mode and all other DEFAULTS keys are present in DB
sequences without bloating API read responses with unexpected keys.

- tab_batch_ng.py: async create_batch with to_thread save/sync

Zero blocking I/O calls remain in UI callbacks.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Adding all DEFAULTS keys to API responses shifted output slot
indices, breaking existing ComfyUI workflow links (tuple index
out of range). Only lora migration remains on the DB read path.

Ensures the project loader API always returns all expected keys
like mode, cfg, etc. even if they were missing from stored data.

Ensures all sequences have required keys like mode, cfg, etc.
from DEFAULTS via setdefault so they persist on next save.

Force float coercion in both migration paths (load_json and DB read)
and override type detection in get_sequence_keys so lora strength
keys always report as FLOAT regardless of JSON deserialization.

Run _migrate_lora_keys on every load_json call so all sequences
get split name/strength keys immediately, not just when the LoRA
expansion is rendered. Next save writes the clean format to disk.

Add _migrate_lora_keys to get_sequence() so the /api endpoints
always return separate lora name and strength keys, even for
data stored in the old <lora:name:strength> format.

Store lora name and strength as independent JSON keys instead of the
combined <lora:name:strength> format. Legacy format is auto-migrated
on load. Timeline preview updated to show all 6 LoRA slots.

Move all save_json/load_json/sync_to_db/DB calls off the event loop
with asyncio.to_thread to prevent UI freezes. Cache graphviz SVG by
DOT source hash (bounded LRU of 20). Replace DELETE-all/re-INSERT in
sync_to_db with UPSERT + targeted DELETE. Add DB indexes, COUNT query,
and reduce graph poll interval to 0.5s.

When current_project in config references a project not found in the
database, show a warning with buttons to either clear the reference

Root cause: save_json + sync_to_db blocked the event loop while
serializing the growing history tree (all snapshots) as JSON,
causing NiceGUI websocket timeout and client reconnect.
- Skip history tree in snapshot deepcopy (copied only to discard)
- Move save_json/sync_to_db to asyncio.to_thread in all callbacks
- Make save_and_snap, commit, sort_by_number, shift_fts,
_add_sequence, apply_mass_update async

- Set reload=False to prevent watchfiles from triggering full page
reloads when JSON/DB files are written during save
- Timeline graph poll timer (200ms) now deactivates itself when its
parent slot is deleted during UI refresh
- Comfy monitor poll timer catches RuntimeError from deleted parent
slots instead of crashing

reload=True was watching all file changes, causing full page reloads
when save_json/save_config wrote .json and .json.tmp files.

onConfigure to read from widget values (which work correctly) and
