🧪 Forge Grid: LoRa x Sampler x Scheduler script

⚙️ Core Logic🛑 Integrated <code>state.interrupt()</code><ul><li>Stop button now halts generation predictably in both XY Grid and Batch Grid modes.</li><li>Added <code>if state.interrupted:</code> checks with graceful early exits using <code>safe_processed()</code>.</li><li>Handles all nested loops to prevent Forge from hanging during interruption.</li></ul>🧩 Grid Layout Logging<ul><li>Added console info before generation:<pre><code>🧩 XY Grid layout → rows=..., cols=..., samplers=..., schedulers=..., weights=...</code></pre>Helps visualize grid setup and total iteration count.</li></ul>↕️ LoRA Weight Orientation Fix<ul><li>When LoRA Label Position = <code>⬅️ Left</code> or <code>➡️ Right</code>, → LoRA weights are now ordered bottom (min) → top (max), matching intuitive Y-axis behavior.</li><li>Implemented by reversing the <code>current_weights</code> list before XY Grid generation.</li></ul>🎨 Prompt / LoRA Handling🧠 Rewritten <code>apply_params()</code><ul><li>LoRA is skipped entirely when <code>weight == 0.0</code>. → No LoRA tag or trigger word is added to the prompt.</li><li>Prevents duplicate trigger words or <code>&lt;lora:...&gt;</code> tags.</li><li>Cleans redundant commas/spaces, keeping prompt formatting consistent.</li><li>New prompt assembly order:<pre><code>[main prompt], &lt;lora:name:weight&gt;, trigger</code></pre></li><li>Metadata no longer contains stray “, , , , ,”.</li></ul>🧩 XY Grid✅ Improved generation loop<ul><li>Proper row/column indexing for vertical vs. horizontal orientation.</li><li>Ensures every generated cell is saved when <code>save_cells=True</code>.</li><li>Compatible with all label positions (<code>Top</code>, <code>Bottom</code>, <code>Left</code>, <code>Right</code>).</li></ul>🧾 Enhanced logging<ul><li>Each iteration now prints detailed progress:<pre><code>🔄[7/36] Sampler='Euler a', Scheduler='Automatic', LoRA='Apone3d', Weight=0.50, Seed=...</code></pre></li><li>Uniform logging style between XY and Batch grids.</li></ul>🧩 Batch Grid⚙️ Refined control flow<ul><li>Added <code>state.interrupt()</code> safety checks to every nested loop.</li><li>Clean exit with clear logs:<pre><code>🛑 Generation manually stopped by user.</code></pre></li><li>LoRA weight = 0.0 now behaves identically to XY Grid — no LoRA, no trigger applied.</li></ul>🧩 Grid validation &amp; saving<ul><li>Improved <code>validate_cells_for_grid()</code> output:<pre><code>🚫 Grid validation issues: ❌ Cell [1,2] is None ...</code></pre></li><li>Prevents saving empty or invalid grids.</li><li>Saved cell filenames now include all relevant parameters:<pre><code>LoRA_W0.50_S-Euler_SchAutomatic_1_2.webp</code></pre></li></ul>💬 Logging &amp; UX<ul><li>Consistent emoji-coded messages: 🏁 start • 🔄 progress • 💾 save • 🛑 interrupt • ✅ done • ❌ error</li><li>All <code>print()</code> calls use <code>flush=True</code> → immediate terminal output.</li><li>Added <code>gc.collect()</code> after grid creation for better memory cleanup.</li></ul>🧰 Internal Improvements<ul><li>Removed redundant <code>build_grid_labels()</code> calls.</li><li>Simplified nested loop logic and unified naming (<code>sampler_label</code>, <code>scheduler_label</code>).</li><li>Standardized <code>get_cell_indices()</code> parameters and <code>orientation</code> handling.</li><li>Minor refactors for clarity and alignment with Forge UI behavior.</li></ul>🧾 Summary🛑 Stop Handling: Integrated <code>state.interrupt()</code>→ Predictable halts↕️ Vertical LoRA: Reversed weights → Bottom=min - Top=max🧠 Prompt Logic: Rebuilt <code>apply_params()</code>→ Clean, deduplicated prompts🧩 XY Grid: Added layout logging → Clear grid overview🧱 Batch Grid: Unified LoRA &amp; trigger logic → Consistent output💬 Logging: Emoji + flush → Readable, real-time feedback🧹 Memory: Added <code>gc.collect()</code> → No residual memory buildup
