- _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.

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.

Logs with perf_counter timing on: file load/save, DB sync, all
render functions, save & snap (with deepcopy/save/sync breakdown),
graphviz cache hit/miss, node restore, and API endpoints.

Prevents 'parent slot deleted' RuntimeError when the timeline
tab is destroyed while the timer is still firing.

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.

- 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

history_tree.py:
- Cycle protection in generate_graph() parent walk
- KeyError → .get() for malformed node data in commit() and generate_graph()
- UUID collision check with for/else raise in commit() and _migrate_legacy()
- RuntimeError → ValueError for consistent exception handling
tab_timeline_ng.py:
- Re-parent children walks to surviving ancestor for batch deletes
- Branch tip deletion re-points to parent instead of removing branch
- Cycle protection in _walk_branch_nodes and _find_branch_for_node
- Full data.clear() restore instead of merge in _restore_node
- Safe .get('data', {}) in restore and preview
- Reset stale branch selection after node deletion
- json.dumps for safe JS string escaping in graphviz renderer
tab_batch_ng.py:
- NaN/inf rejection in dict_number with math.isfinite()
- _safe_int used in recalc_vace, update_mode_label, frame_to_skip
- Uncaught ValueError from htree.commit() caught with user notification
tab_comfy_ng.py:
- asyncio.get_event_loop() → get_running_loop()
utils.py:
- Atomic writes for save_config and save_snippets
- save_config extra_data can't override explicit last_dir/favorites

The c{id} DOM ID pattern was wrong. Use document.querySelector with
the timeline-graph class instead, with retries until g.node elements
are present in the DOM.

Move JS back to ui.run_javascript() with retry-based DOM lookup
using NiceGUI's element ID (c{id}). CSS stays inline via style tag.
Retries up to 10 times at 50ms intervals to handle Vue async render.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Previous approach used ui.run_javascript with getElement() which
failed due to Vue rendering timing. Now embeds the script and style
directly inside the HTML content so there are no DOM lookup or
timing issues — the script runs inline when parsed.

The click handlers weren't attaching because getElementById couldn't
find the container — Python's id() generated IDs that didn't survive
NiceGUI's DOM rendering. Now uses getElement() with the NiceGUI
element ID and defers JS via requestAnimationFrame to ensure the
DOM is ready.

Stop replacing the SVG's width/height attributes — this was shrinking
the graph to fit the container. Instead keep graphviz's native pt
dimensions and let the scroll container handle overflow.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Drop the fixed height attribute entirely instead of setting it to
"auto", which SVGs don't support. The viewBox attribute handles
proportional scaling when only width="100%" is set.

Add click-to-select functionality to the graphviz SVG timeline graph.
Clicking a node highlights it with an amber border, auto-switches the
branch selector, and updates the node manager panel. The SVG is now
responsive (100% width, scroll container) instead of fixed-size.

Replace flat dropdown with branch selector showing node counts,
scrollable node list with HEAD/tip badges, and inline actions panel.

- Deep-copy node data on restore to prevent edits from mutating
stored history snapshots
- Guard glob calls against non-existent current_dir
- Read current selection at delete time instead of using stale
render-time capture

Replace red accent with amber, add Inter font, introduce 4-level depth
palette via CSS variables, expand padding/gaps, wrap sidebar and content
sections in cards, add section/subsection header typography classes, and
style scrollbars for dark theme. Pure visual changes — no functional or
data-flow modifications.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add page/sidebar background contrast, wrap action button rows,
ensure dark text in inputs, and improve timeline card highlight colors.
