better default/min heights

Adds a reusable agent skill for managing cherry-pick backports across
stable release branches.

## What
Agent skill at `.claude/skills/backport-management/` with routing-table
SKILL.md + 4 reference files (discovery, analysis, execution, logging).

## Why
Codifies lessons from backporting 57 PRs across cloud/1.41, core/1.41,
and core/1.40. Makes future backport sessions faster and less
error-prone.

## Key learnings baked in
- Cloud-only PRs must not be backported to `core/*` branches (wasted
effort)
- Wave verification (`pnpm typecheck`) between batches to catch breakage
early
- Human review required for non-trivial conflict resolutions before
admin-merge
- MUST vs SHOULD decision guide with clear criteria
- Continuous backporting preference over bulk sessions
- Mermaid diagram as final session deliverable
- Conflict triage table (never skip based on file count alone)
- `gh api` for labels instead of `gh pr edit` (Projects Classic
deprecation)

+description: Manages cherry-pick backports across stable release branches. Discovers candidates from Slack/git, analyzes dependencies, resolves conflicts via worktree, and logs results. Use when asked to backport, cherry-pick to stable, manage release branches, do stable branch maintenance, or run a backport session.

+
+# Backport Management
+
+Cherry-pick backport management for Comfy-Org/ComfyUI_frontend stable release branches.
+
+## Quick Start
+
+1. **Discover** — Collect candidates from Slack bot + git log gap (`reference/discovery.md`)
+2. **Analyze** — Categorize MUST/SHOULD/SKIP, check deps (`reference/analysis.md`)
+3. **Plan** — Order by dependency (leaf fixes first), group into waves per branch
+4. **Execute** — Label-driven automation → worktree fallback for conflicts (`reference/execution.md`)
+5. **Verify** — After each wave, verify branch integrity before proceeding
+6. **Log & Report** — Generate session report with mermaid diagram (`reference/logging.md`)
+
+## System Context
+
+| Item           | Value                                             |
+| -------------- | ------------------------------------------------- |
+| Repo           | `~/ComfyUI_frontend` (Comfy-Org/ComfyUI_frontend) |
+| Merge strategy | Squash merge (`gh pr merge --squash --admin`)     |
+| Automation     | `pr-backport.yaml` GitHub Action (label-driven)   |
+| Tracking dir   | `~/temp/backport-session/`                        |
+
+## Branch Scope Rules
+
+**Critical: Match PRs to the correct target branches.**
+
+| Branch prefix | Scope                          | Example                                   |
+| ------------- | ------------------------------ | ----------------------------------------- |
+| `cloud/*`     | Cloud-hosted ComfyUI only      | App mode, cloud auth, cloud-specific UI   |
+| `core/*`      | Local/self-hosted ComfyUI only | Core editor, local workflows, node system |
+
+**⚠️ NEVER backport cloud-only PRs to `core/*` branches.** Cloud-only changes (app mode, cloud auth, cloud billing UI, cloud-specific API calls) are irrelevant to local users and waste effort. Before backporting any PR to a `core/*` branch, check:
+
+- Does the PR title/description mention "app mode", "cloud", or cloud-specific features?
+- Does the PR only touch files like `appModeStore.ts`, cloud auth, or cloud-specific components?
+- If yes → skip for `core/*` branches (may still apply to `cloud/*` branches)
+
+## ⚠️ Gotchas (Learn from Past Sessions)
+
+### Use `gh api` for Labels — NOT `gh pr edit`
+
+`gh pr edit --add-label` triggers Projects Classic deprecation errors. Always use:
+
+```bash
+gh api repos/Comfy-Org/ComfyUI_frontend/issues/$PR/labels \
+  -f "labels[]=needs-backport" -f "labels[]=TARGET_BRANCH"
+```
+
+### Automation Over-Reports Conflicts
+
+The `pr-backport.yaml` action reports more conflicts than reality. `git cherry-pick -m 1` with git auto-merge handles many cases the automation can't. Always attempt manual cherry-pick before skipping.
+
+### Never Skip Based on Conflict File Count
+
+12 or 27 conflicting files can be trivial (snapshots, new files). **Categorize conflicts first**, then decide. See Conflict Triage below.
+
+## Conflict Triage
+
+**Always categorize before deciding to skip. High conflict count ≠ hard conflicts.**
+
+| Type                         | Symptom                              | Resolution                                                      |
+| ---------------------------- | ------------------------------------ | --------------------------------------------------------------- |
+| **Binary snapshots (PNGs)**  | `.png` files in conflict list        | `git checkout --theirs $FILE && git add $FILE` — always trivial |
+| **Modify/delete (new file)** | PR introduces files not on target    | `git add $FILE` — keep the new file                             |
+| **Modify/delete (removed)**  | Target removed files the PR modifies | `git rm $FILE` — file no longer relevant                        |
+| **Content conflicts**        | Marker-based (`<<<<<<<`)             | Accept theirs via python regex (see below)                      |
+| **Add/add**                  | Both sides added same file           | Accept theirs, verify no logic conflict                         |
+| **Locale/JSON files**        | i18n key additions                   | Accept theirs, validate JSON after                              |
+
+```python
+# Accept theirs for content conflicts
+import re
+pattern = r'<<<<<<< HEAD\n(.*?)=======\n(.*?)>>>>>>> [^\n]+\n?'
+content = re.sub(pattern, r'\2', content, flags=re.DOTALL)
+```
+
+### Escalation Triggers (Flag for Human)
+
+- **Package.json/lockfile changes** → skip on stable (transitive dep regression risk)
+- **Core type definition changes** → requires human judgment
+- **Business logic conflicts** (not just imports/exports) → requires domain knowledge
+- **Admin-merged conflict resolutions** → get human review of the resolution before continuing the wave
+
+## Auto-Skip Categories
+
+Skip these without discussion:
+
+- **Dep refresh PRs** — Risk of transitive dep regressions on stable. Cherry-pick individual CVE fixes instead.
+- **CI/tooling changes** — Not user-facing
+- **Test-only / lint rule changes** — Not user-facing
+- **Revert pairs** — If PR A reverted by PR B, skip both. If fixed version (PR C) exists, backport only C.
+- **Features not on target branch** — e.g., Painter, GLSLShader, appModeStore on core/1.40
+- **Cloud-only PRs on core/\* branches** — App mode, cloud auth, cloud billing. These only affect cloud-hosted ComfyUI.
+
+## Wave Verification
+
+After merging each wave of PRs to a target branch, verify branch integrity before proceeding:
+
+```bash
+# Fetch latest state of target branch
+git fetch origin TARGET_BRANCH
+
+# Quick smoke check: does the branch build?
+git worktree add /tmp/verify-TARGET origin/TARGET_BRANCH
+cd /tmp/verify-TARGET
+source ~/.nvm/nvm.sh && nvm use 24 && pnpm install && pnpm typecheck
+git worktree remove /tmp/verify-TARGET --force
+```
+
+If typecheck fails, stop and investigate before continuing. A broken branch after wave N means all subsequent waves will compound the problem.
+
+## Continuous Backporting Recommendation
+
+Large backport sessions (50+ PRs) are expensive and error-prone. Prefer continuous backporting:
+
+- Backport bug fixes as they merge to main (same day or next day)
+- Use the automation labels immediately after merge
+- Reserve session-style bulk backporting for catching up after gaps
+- When a release branch is created, immediately start the continuous process
+
+## Quick Reference
+
+### Label-Driven Automation (default path)
+
+```bash
+gh api repos/Comfy-Org/ComfyUI_frontend/issues/$PR/labels \
+  -f "labels[]=needs-backport" -f "labels[]=TARGET_BRANCH"
+# Wait 3 min, check: gh pr list --base TARGET_BRANCH --state open
+```
+
+### Manual Worktree Cherry-Pick (conflict fallback)
+
+```bash
+git worktree add /tmp/backport-$BRANCH origin/$BRANCH
+cd /tmp/backport-$BRANCH
+git checkout -b backport-$PR-to-$BRANCH origin/$BRANCH
+git cherry-pick -m 1 $MERGE_SHA
+# Resolve conflicts, push, create PR, merge
+```
+
+### PR Title Convention
+
+```
+[backport TARGET_BRANCH] Original Title (#ORIGINAL_PR)

+# Analysis & Decision Framework
+
+## Categorization
+
+| Category             | Criteria                                                                                                  | Action                                                                     |
+| -------------------- | --------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------- |
+| **MUST**             | User-facing bug, crash, data corruption, security. Clear breakage that users will hit.                    | Backport (with deps if needed)                                             |
+| **SHOULD**           | UX improvement, minor bug, small dep chain. No user-visible breakage if skipped, but improves experience. | Backport if clean cherry-pick; defer if conflict resolution is non-trivial |
+| **SKIP**             | CI/tooling, test-only, lint rules, cosmetic, dep refresh                                                  | Skip with documented reason                                                |
+| **NEEDS DISCUSSION** | Large dep chain, unclear risk/benefit, touches core types                                                 | Flag for human                                                             |
+
+### MUST vs SHOULD Decision Guide
+
+When unsure, ask: "If a user on this stable branch reports this issue, would we consider it a bug?"
+
+- **Yes** → MUST. The fix addresses broken behavior.
+- **No, but it's noticeably better** → SHOULD. The fix is a quality-of-life improvement.
+- **No, and it's cosmetic or internal** → SKIP.
+
+For SHOULD items with conflicts: if conflict resolution requires more than trivial accept-theirs patterns (content conflicts in business logic, not just imports), downgrade to SKIP or escalate to NEEDS DISCUSSION.
+
+## Branch Scope Filtering
+
+**Before categorizing, filter by branch scope:**
+
+| Target branch | Skip if PR is...                                                    |
+| ------------- | ------------------------------------------------------------------- |
+| `core/*`      | Cloud-only (app mode, cloud auth, cloud billing, cloud-specific UI) |
+| `cloud/*`     | Local-only features not present on cloud branch                     |
+
+Cloud-only PRs backported to `core/*` are wasted effort — `core/*` branches serve local/self-hosted users who never see cloud features. Check PR titles, descriptions, and files changed for cloud-specific indicators.
+
+## Features Not on Stable Branches
+
+Check before backporting — these don't exist on older branches:
+
+- **Painter** (`src/extensions/core/painter.ts`) — not on core/1.40
+- **GLSLShader** — not on core/1.40
+- **App builder** — check per branch
+- **appModeStore.ts** — not on core/1.40
+
+## Dep Refresh PRs
+
+Always SKIP on stable branches. Risk of transitive dependency regressions outweighs audit cleanup benefit. If a specific CVE fix is needed, cherry-pick that individual fix instead.
+
+## Revert Pairs
+
+If PR A is reverted by PR B:
+
+- Skip BOTH A and B
+- If a fixed version exists (PR C), backport only C
+
+## Dependency Analysis
+
+```bash
+# Find other PRs that touched the same files
+gh pr view $PR --json files --jq '.files[].path' | while read f; do
+  git log --oneline origin/TARGET..$MERGE_SHA -- "$f"
+done
+```
+
+## Human Review Checkpoint
+
+Present decisions.md before execution. Include:
+
+1. All MUST/SHOULD/SKIP categorizations with rationale
+2. Questions for human (feature existence, scope, deps)
+3. Estimated effort per branch

+# Execution Workflow
+
+## Per-Branch Execution Order
+
+1. Smallest gap first (validation run)
+2. Medium gap next (quick win)
+3. Largest gap last (main effort)
+
+## Step 1: Label-Driven Automation (Batch)
+
+```bash
+# Add labels to all candidates for a target branch
+for pr in $PR_LIST; do
+  gh api repos/Comfy-Org/ComfyUI_frontend/issues/$pr/labels \
+    -f "labels[]=needs-backport" -f "labels[]=TARGET_BRANCH" --silent
+  sleep 2
+done
+
+# Wait 3 minutes for automation
+sleep 180
+
+# Check which got auto-PRs
+gh pr list --base TARGET_BRANCH --state open --limit 50 --json number,title
+```
+
+## Step 2: Review & Merge Clean Auto-PRs
+
+```bash
+for pr in $AUTO_PRS; do
+  # Check size
+  gh pr view $pr --json title,additions,deletions,changedFiles \
+    --jq '"Files: \(.changedFiles), +\(.additions)/-\(.deletions)"'
+  # Admin merge
+  gh pr merge $pr --squash --admin
+  sleep 3
+done
+```
+
+## Step 3: Manual Worktree for Conflicts
+
+```bash
+git fetch origin TARGET_BRANCH
+git worktree add /tmp/backport-TARGET origin/TARGET_BRANCH
+cd /tmp/backport-TARGET
+
+for PR in ${CONFLICT_PRS[@]}; do
+  # Refresh target ref so each branch is based on current HEAD
+  git fetch origin TARGET_BRANCH
+  git checkout origin/TARGET_BRANCH
+
+  git checkout -b backport-$PR-to-TARGET origin/TARGET_BRANCH
+  git cherry-pick -m 1 $MERGE_SHA
+
+  # If conflict — NEVER skip based on file count alone!
+  # Categorize conflicts first: binary PNGs, modify/delete, content, add/add
+  # See SKILL.md Conflict Triage table for resolution per type.
+
+  # Resolve all conflicts, then:
+  git add .
+  GIT_EDITOR=true git cherry-pick --continue
+
+  git push origin backport-$PR-to-TARGET
+  NEW_PR=$(gh pr create --base TARGET_BRANCH --head backport-$PR-to-TARGET \
+    --title "[backport TARGET] TITLE (#$PR)" \
+    --body "Backport of #$PR..." | grep -oP '\d+$')
+  gh pr merge $NEW_PR --squash --admin
+  sleep 3
+done
+
+# Cleanup
+cd -
+git worktree remove /tmp/backport-TARGET --force
+```
+
+**⚠️ Human review for conflict resolutions:** When admin-merging a PR where you manually resolved conflicts (especially content conflicts beyond trivial accept-theirs), pause and present the resolution diff to the human for review before merging. Trivial resolutions (binary snapshots, modify/delete, locale key additions) can proceed without review.
+
+## Step 4: Wave Verification
+
+After completing all PRs in a wave for a target branch:
+
+```bash
+git fetch origin TARGET_BRANCH
+git worktree add /tmp/verify-TARGET origin/TARGET_BRANCH
+cd /tmp/verify-TARGET
+source ~/.nvm/nvm.sh && nvm use 24 && pnpm install && pnpm typecheck
+git worktree remove /tmp/verify-TARGET --force
+```
+
+If verification fails, stop and fix before proceeding to the next wave. Do not compound problems across waves.
+
+## Conflict Resolution Patterns
+
+### 1. Content Conflicts (accept theirs)
+
+```python
+import re
+pattern = r'<<<<<<< HEAD\n(.*?)=======\n(.*?)>>>>>>> [^\n]+\n?'
+content = re.sub(pattern, r'\2', content, flags=re.DOTALL)
+```
+
+### 2. Modify/Delete (two cases!)
+
+```bash
+# Case A: PR introduces NEW files not on target → keep them
+git add $FILE
+
+# Case B: Target REMOVED files the PR modifies → drop them
+git rm $FILE
+```
+
+### 3. Binary Files (snapshots)
+
+```bash
+git checkout --theirs $FILE && git add $FILE
+```
+
+### 4. Locale Files
+
+Usually adding new i18n keys — accept theirs, validate JSON:
+
+```bash
+python3 -c "import json; json.load(open('src/locales/en/main.json'))" && echo "Valid"
+```
+
+## Merge Conflicts After Other Merges
+
+When merging multiple PRs to the same branch, later PRs may conflict with earlier merges:
+
+```bash
+git fetch origin TARGET_BRANCH
+git rebase origin/TARGET_BRANCH
+# Resolve new conflicts
+git push --force origin backport-$PR-to-TARGET
+sleep 20  # Wait for GitHub to recompute merge state
+gh pr merge $PR --squash --admin
+```
+
+## Lessons Learned
+
+1. **Automation reports more conflicts than reality** — `cherry-pick -m 1` with git auto-merge handles many "conflicts" the automation can't
+2. **Never skip based on conflict file count** — 12 or 27 conflicts can be trivial (snapshots, new files). Categorize first: binary PNGs, modify/delete, content, add/add.
+3. **Modify/delete goes BOTH ways** — if the PR introduces new files (not on target), `git add` them. If target deleted files the PR modifies, `git rm`.
+4. **Binary snapshot PNGs** — always `git checkout --theirs && git add`. Never skip a PR just because it has many snapshot conflicts.
+5. **Batch label additions need 2s delay** between API calls to avoid rate limits
+6. **Merging 6+ PRs rapidly** can cause later PRs to become unmergeable — wait 20-30s for GitHub to recompute merge state
+7. **appModeStore.ts, painter files, GLSLShader files** don't exist on core/1.40 — `git rm` these
+8. **Always validate JSON** after resolving locale file conflicts
+9. **Dep refresh PRs** — skip on stable branches. Risk of transitive dep regressions outweighs audit cleanup. Cherry-pick individual CVE fixes instead.
+10. **Verify after each wave** — run `pnpm typecheck` on the target branch after merging a batch. Catching breakage early prevents compounding errors.
+11. **Cloud-only PRs don't belong on core/\* branches** — app mode, cloud auth, and cloud-specific UI changes are irrelevant to local users. Always check PR scope against branch scope before backporting.

+# Change Tracker (Undo/Redo System)
+
+The `ChangeTracker` class (`src/scripts/changeTracker.ts`) manages undo/redo
+history by comparing serialized graph snapshots.
+
+## How It Works
+
+`checkState()` is the core method. It:
+
+1. Serializes the current graph via `app.rootGraph.serialize()`
+2. Deep-compares the result against the last known `activeState`
+3. If different, pushes `activeState` onto `undoQueue` and replaces it
+
+**It is not reactive.** Changes to the graph (widget values, node positions,
+links, etc.) are only captured when `checkState()` is explicitly triggered.
+
+## Automatic Triggers
+
+These are set up once in `ChangeTracker.init()`:
+
+| Trigger                             | Event / Hook                                       | What It Catches                                     |
+| ----------------------------------- | -------------------------------------------------- | --------------------------------------------------- |
+| Keyboard (non-modifier, non-repeat) | `window` `keydown`                                 | Shortcuts, typing in canvas                         |
+| Modifier key release                | `window` `keyup`                                   | Releasing Ctrl/Shift/Alt/Meta                       |
+| Mouse click                         | `window` `mouseup`                                 | General clicks on native DOM                        |
+| Canvas mouse up                     | `LGraphCanvas.processMouseUp` override             | LiteGraph canvas interactions                       |
+| Number/string dialog                | `LGraphCanvas.prompt` override                     | Dialog popups for editing widgets                   |
+| Context menu close                  | `LiteGraph.ContextMenu.close` override             | COMBO widget menus in LiteGraph                     |
+| Active input element                | `bindInput` (change/input/blur on focused element) | Native HTML input edits                             |
+| Prompt queued                       | `api` `promptQueued` event                         | Dynamic widget changes on queue                     |
+| Graph cleared                       | `api` `graphCleared` event                         | Full graph clear                                    |
+| Transaction end                     | `litegraph:canvas` `after-change` event            | Batched operations via `beforeChange`/`afterChange` |
+
+## When You Must Call `checkState()` Manually
+
+The automatic triggers above are designed around LiteGraph's native DOM
+rendering. They **do not cover**:
+
+- **Vue-rendered widgets** — Vue handles events internally without triggering
+  native DOM events that the tracker listens to (e.g., `mouseup` on a Vue
+  dropdown doesn't bubble the same way as a native LiteGraph widget click)
+- **Programmatic graph mutations** — Any code that modifies the graph outside
+  of user interaction (e.g., applying a template, pasting nodes, aligning)
+- **Async operations** — File uploads, API calls that change widget values
+  after the initial user gesture
+
+### Pattern for Manual Calls
+
+```typescript
+import { useWorkflowStore } from '@/platform/workflow/management/stores/workflowStore'
+
+// After mutating the graph:
+useWorkflowStore().activeWorkflow?.changeTracker?.checkState()
+```
+
+### Existing Manual Call Sites
+
+These locations already call `checkState()` explicitly:
+
+- `WidgetSelectDropdown.vue` — After dropdown selection and file upload
+- `ColorPickerButton.vue` — After changing node colors
+- `NodeSearchBoxPopover.vue` — After adding a node from search
+- `useAppSetDefaultView.ts` — After setting default view
+- `useSelectionOperations.ts` — After align, copy, paste, duplicate, group
+- `useSelectedNodeActions.ts` — After pin, bypass, collapse
+- `useGroupMenuOptions.ts` — After group operations
+- `useSubgraphOperations.ts` — After subgraph enter/exit
+- `useCanvasRefresh.ts` — After canvas refresh
+- `useCoreCommands.ts` — After metadata/subgraph commands
+- `workflowService.ts` — After workflow service operations
+
+## Transaction Guards
+
+For operations that make multiple changes that should be a single undo entry:
+
+```typescript
+changeTracker.beforeChange()
+// ... multiple graph mutations ...
+changeTracker.afterChange() // calls checkState() when nesting count hits 0
+```
+
+The `litegraph:canvas` custom event also supports this with `before-change` /
+`after-change` sub-types.
+
+## Key Invariants
+
+- `checkState()` is a no-op during `loadGraphData` (guarded by
+  `isLoadingGraph`) to prevent cross-workflow corruption
+- `checkState()` is a no-op when `changeCount > 0` (inside a transaction)
+- `undoQueue` is capped at 50 entries (`MAX_HISTORY`)
+- `graphEqual` ignores node order and `ds` (pan/zoom) when comparing
