v0.2.7-alpha - Cross-Tab State Isolation, Stateless Python

Dazzle Command v0.2.7-alpha

Workflow orchestration node for ComfyUI — coordinate seed control and execution gates from a single play/pause toggle. Part of the DazzleNodes collection.

What's New in v0.2.7-alpha

Cross-Tab State Contamination Fix

Opening a second workflow tab (even the same file, even without running it) used to contaminate the first tab's play/pause state and invalidate its cache. Root cause: node IDs collide across tabs, so every store keyed by bare node ID was cross-tab shared.

The fix removes server-side state entirely:

• State lives on each node object plus node.properties (persisted per workflow-tab draft — survives tab switches and page reloads)
• At queue time, JS injects the live state into the node's prompt inputs as a hidden dazzle_state input — per-queue and per-tab by construction, and part of ComfyUI's cache key (toggling play/pause is exactly the change that should re-execute)
• The nodeStates map, workflow-UUID guard, sys._dazzle_command_states registry, IS_CHANGED, and the /dazzle-command/set-state API endpoint are all gone (net −79 lines)

Other Fixes

• Reconfigure protection: mid-session graph reconfigures replaying stale snapshots can no longer revert your Play/Pause clicks (per-node-object guard replacing the v0.2.5 workflow-UUID approach)
• Honest seed display: the seed bar no longer adopts seeds from SmartResCalc nodes that aren't noodle-connected to this DazzleCommand — an unconnected node now shows -- instead of masquerading as working orchestration
• Seed bar values persist per tab via node.properties
• Headless/API prompts (no JS) default to paused, as before

Installation

Install via ComfyUI Manager or clone:

cd ComfyUI/custom_nodes
git clone https://github.com/DazzleNodes/ComfyUI-DazzleCommand.git
