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.

splines=ortho triggers a trapezoid-table overflow assertion in
graphviz's dot layout engine on complex graphs. polyline gives
similar angled edges without the crash.

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.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
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.

- Deep-copy node data on restore to prevent edits from mutating
stored history snapshots
- Guard glob calls against non-existent current_dir

- Sync dict_input/dict_textarea/LoRA inputs on update:model-value
(not just blur) to prevent silent data loss on quick saves
- Split LoRA into name + strength fields, default strength to 1.0
- Stack LoRAs one per line instead of 3-card row
- Collapse "Add New Sequence from Source File" into expansion
- Add file selector to Pane A in dual-pane mode
- Clear secondary pane state on directory change
- Fix file radio resetting to first file on refresh
- Handle bare-list JSON files and inf/nan edge cases

dict_number() only wrote to seq[key] on blur, so changing a value
(e.g. via spinner arrows) and immediately clicking Save could race
the save ahead of the blur on the server. Now also syncs on
update:model-value so the dict is always current.

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.

dict_number() defaulted to 0 while mode_label used default of 1,
causing visual inconsistency when 'vace schedule' key is missing.

NiceGUI's ui.number returns float values, so seeds, steps, dimensions
etc. were being stored as floats (e.g. 42.0) instead of integers.

Update badge, installation instructions, port references, and file
structure to reflect the migration from Streamlit to NiceGUI.

- Use set_options() instead of direct .options assignment (3 locations)
so dropdown changes actually reach the browser
- Wrap res.json() in try/except for non-JSON server responses
- Deep copy in create_batch and promote to match rest of codebase

- save_config calls now pass full config to preserve comfy settings
- Mass update section moved inside refreshable to stay in sync
- Deep copy source data to prevent shared mutable references
- Clipboard copy uses json.dumps instead of repr() for safe JS
- Comfy monitor uses async IO (run_in_executor) to avoid blocking
- Auto-timeout now updates checkbox and refreshes live view UI

The recovery formula now matches the storage formula per mode:
End Extend subtracts only A, Pre Extend subtracts only B.

- Formula changes per VACE schedule: End Extend uses base+A,
Pre Extend uses base+B, others use base+A+B
- Snap total to 4n+1 to match VACE sampler
- Show mode name label next to schedule number
- Add mode reference popover with all formulas

UI shows the base value (vace_length - input_a - input_b) for editing,
saves the computed total back to the JSON.

Types were lost on workflow reload because only key names were stored.
Now both keys and types are saved in hidden widgets and restored by
onConfigure, so colored connector dots persist without needing Refresh.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
API route now returns types alongside keys. JS sets output slot type
accordingly, giving correct colored dots and type-safe connections.

Diff new keys against existing outputs instead of remove-all/add-all.
Reuses slot objects for matching key names so links stay connected.
Only disconnects links on keys that were actually removed.

Direct array manipulation bypassed LiteGraph's internal slot tracking,
causing output names to show as defaults instead of JSON key names.

- Moved end_frame to main settings area (i2v field, not VACE)
- Added vace_length (default 49) with computed output display

The inline check caused mismatches between typed and resolved paths.
Now uses on_change callback that always sets _sync_nav_path flag,
so the widget is synced to the canonical current_dir path on the
next rerun before the widget renders.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Use _sync_nav_path flag to defer the revert to the next rerun, before
the widget is instantiated.

The on_change callback had timing issues with Streamlit's session state,
causing user input to be discarded. Now checks the widget value inline
after render and triggers rerun on valid directory change.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The nav_path_input was force-overwritten on every rerun, causing
Streamlit to discard user edits before the on_change callback could
process them. Now only syncs on first load or external changes
(favorites). Also resets loaded_file on dir change and reverts
widget on invalid paths.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The old_fts value was read from the data dict which gets mutated
in-place by widget renders, so on button click rerun delta was always 0.
Now the saved value is captured once per ui_reset_token cycle.

Source file picker now shows all sequences in the selected file with a
dropdown, replacing the outdated history entry selector. Both "From

Sub-segments use parent*1000+index numbering (e.g. 2001 = Sub #2.1) so
ComfyUI nodes can reference them via integer sequence_number without
code changes. Adds clone-as-sub button, visual distinction in expander
labels, sort-by-number button, and fixes auto-numbering/frame_to_skip
shift to work correctly with sub-segments.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Adds a "Shift ↓" button next to Frame to Skip in VACE Settings that
applies the change delta to all sequences with a higher sequence_number.
Uses sequence_number field ordering, not array position.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
get_batch_item now searches for the item whose sequence_number field
matches the requested number, instead of using array position. Falls
back to index-based lookup for data without sequence_number fields.

Adds a "Select to Delete" toggle that enables batch deletion mode.
When active, clicking graph nodes or checking linear log checkboxes
selects them (highlighted in red), and a "Delete N Nodes" button
performs batch deletion with backup, branch tip cleanup, and HEAD
reassignment.

- Delete sequence: add ui_reset_token increment to prevent shifted
sequences from inheriting deleted sequence's widget state
- Promote: update data_cache with single_data so UI reflects the
file format change without requiring a manual refresh
- Mass update & clone: use copy.deepcopy to avoid shared mutable
references between sequences

These fields were previously gated behind filename checks ("vace"/"i2v"
