feat(recipes): restore Copy Recipe Syntax button in recipe modal header

- Add an icon-only copy button next to Send to ComfyUI in the header actions row, styled as a textless variant of the neighboring pill buttons - Restore fetchAndCopyRecipeSyntax() wiring against the existing /api/lm/recipe/{id}/syntax endpoint (context menu action unaffected) - Add recipes.actions.copyRecipeSyntax i18n key, reusing the existing per-locale translations of the identical context menu string - Sync modal test fixtures and add copySyntax tests
fix(recipes): render reconnect form for hash-invalid LoRAs in recipe modal

 # LoRa Manager E2E Testing

-This skill provides workflows and utilities for end-to-end testing of LoRa Manager using Chrome DevTools MCP.
+End-to-end testing of LoRa Manager standalone mode using Chrome DevTools MCP.

-## Prerequisites
+## When to Use — and When NOT To

- LoRa Manager project cloned and dependencies installed (`pip install -r requirements.txt`)
- Chrome browser available for debugging
- Chrome DevTools MCP connected
+E2E runs are slow and token-heavy. Reach for them only when the question genuinely
+spans server + browser (routing, scan persistence, websocket updates, EXIF writes).

-## Quick Start Workflow
+- **Default to unit/component tests first**: `npm run test:js` (Vitest/jsdom) covers
+  DOM rendering, modal behavior, event handling and API-client calls deterministically
+  in seconds. Backend logic goes through `pytest`. A UI-behavior question answered by
+  jsdom MUST NOT be escalated to E2E.
+- **Use E2E only when** the behavior cannot be observed without a live server and a
+  real browser, e.g. template rendering through the aiohttp server, scanner → SQLite
+  persistence → API → DOM round-trips, or real EXIF/image writes.
+- If you start an E2E and realize a unit test would answer the question, stop and
+  switch.

-### 1. Start LoRa Manager Standalone
+**Browser driver is fixed: Chrome DevTools MCP.** Do not substitute kimi-webbridge —
+it operates on the user's real browser (real tabs, real sessions, synthetic
+`isTrusted=false` events), which breaks the isolation this skill requires and lacks
+the console/network inspection E2E debugging relies on. kimi-webbridge is for
+interactive browsing with the user's real login sessions, not for sandboxed E2E.

-```python
-# Use the provided script to start the server
-python .agents/skills/lora-manager-e2e/scripts/start_server.py --port 8188
-```
+## Conventions

-Or manually:
-```bash
-cd /home/miao/workspace/ComfyUI/custom_nodes/ComfyUI-Lora-Manager
-python standalone.py --port 8188
-```
+- **`{PORT}`**: default candidate `8188`, but it is **commonly occupied by a live
+  ComfyUI** — always check first (`ss -tlnp | grep ':{PORT}'`) and use a free port
+  (e.g. `8199`). Substitute the chosen port everywhere below. Never kill a process
+  you did not start for this E2E.
+- **`<repo-root>`**: the repository/worktree root; run all commands from there.
+- **`<sandbox>`**: a throwaway dir, e.g. `/tmp/opencode/<plan>-e2e`.

-Wait for server ready message before proceeding.
+## SANDBOX (MANDATORY)

-### 2. Open Chrome Debug Mode
+> Every E2E run MUST target a throwaway sandbox, never real user data.
+
+1. **Explicit settings directory**: always launch with `--settings-path <sandbox>/settings`.
+   This pins ALL runtime data (`settings.json`, `cache/`, `backups/`, `logs/`, `stats/`,
+   `wildcards/`) under the sandbox. **Never** create `<repo-root>/settings.json` — the repo
+   folder is usually the real ComfyUI plugin folder and a portable settings file there is
+   read by the real instance.
+2. **Sandboxed library paths**: point `folder_paths` / `recipes_path` /
+   `example_images_path` at disposable dirs under `<sandbox>` — never the real library,
+   real recipe dir, or real settings:
+
+   ```json
+   {
+     "folder_paths": {
+       "loras": ["<sandbox>/models/loras"],
+       "checkpoints": ["<sandbox>/models/checkpoints"],
+       "unet": ["<sandbox>/models/checkpoints"],
+       "diffusers": []
+     },
+     "recipes_path": "<sandbox>/recipes",
+     "example_images_path": "<sandbox>/example_images"
+   }
+   ```
+
+3. **Real-data protection proof**: before starting and after finishing, snapshot the real
+   config and recipe library and confirm they are byte-identical; also confirm
+   `<repo-root>` gained no `settings.json` or `cache/`:
+
+   ```bash
+   sha256sum ~/.config/ComfyUI-LoRA-Manager/settings.json > <sandbox>/settings.before.sha256
+   ls ~/models/recipes/*.recipe.json 2>/dev/null | wc -l > <sandbox>/recipes-count.before.txt
+   # AFTER the run: record again and diff. Any change = the run leaked into real data.
+   ```
+
+## Quick Start

 ```bash
-# Chrome with remote debugging on port 9222
-google-chrome --remote-debugging-port=9222 --user-data-dir=/tmp/chrome-lora-manager http://127.0.0.1:8188/loras
+cd <repo-root>
+# 1. Sandbox
+mkdir -p <sandbox>/settings <sandbox>/models/{loras,checkpoints} <sandbox>/{recipes,example_images}
+#    write <sandbox>/settings/settings.json per the SANDBOX example
+# 2. Port
+ss -tlnp | grep ':{PORT}' || echo "port {PORT} is free"
+# 3. Server — MUST be fully detached (a plain background & dies with the shell);
+#    the helper enforces this and manages its own pidfile
+python .agents/skills/lora-manager-e2e/scripts/start_server.py \
+  --port {PORT} --settings-path <sandbox>/settings --wait --timeout 30 --detach
+ss -tlnp | grep ':{PORT}'   # verify listening BEFORE proceeding
+# 4. Chrome with remote debugging, then connect Chrome DevTools MCP (verify via list_pages)
+google-chrome --remote-debugging-port=9222 --user-data-dir=/tmp/chrome-lora-manager http://127.0.0.1:{PORT}/loras
 ```

-### 3. Connect Chrome DevTools MCP
+Then drive the UI with the MCP tools (`take_snapshot`, `click`, `fill`, `fill_form`,
+`evaluate_script`, `wait_for`, `list_network_requests`, `list_console_messages`) —
+see [references/mcp-cheatsheet.md](references/mcp-cheatsheet.md) for patterns.

-Ensure the MCP server is connected to Chrome at `http://localhost:9222`.
-
-### 4. Navigate and Interact
-
-Use Chrome DevTools MCP tools to:
- Take snapshots: `take_snapshot`
- Click elements: `click`
- Fill forms: `fill` or `fill_form`
- Evaluate scripts: `evaluate_script`
- Wait for elements: `wait_for`
-
-## Common E2E Test Patterns
-
-### Pattern: Full Page Load Verification
-
-```python
-# Navigate to LoRA list page
-navigate_page(type="url", url="http://127.0.0.1:8188/loras")
-
-# Wait for page to load
-wait_for(text="LoRAs", timeout=10000)
-
-# Take snapshot to verify UI state
-snapshot = take_snapshot()
-```
-
-### Pattern: Restart Server for Configuration Changes
-
-```python
-# Stop current server (if running)
-# Start with new configuration
-python .agents/skills/lora-manager-e2e/scripts/start_server.py --port 8188 --restart
-
-# Wait and refresh browser
-navigate_page(type="reload", ignoreCache=True)
-wait_for(text="LoRAs", timeout=15000)
-```
-
-### Pattern: Verify Backend API via Frontend
-
-```python
-# Execute script in browser to call backend API
-result = evaluate_script(function="""
-async () => {
-  const response = await fetch('/loras/api/list');
-  const data = await response.json();
-  return { count: data.length, firstItem: data[0]?.name };
-}
-""")
-```
-
-### Pattern: Form Submission Flow
-
-```python
-# Fill a form (e.g., search or filter)
-fill_form(elements=[
-    {"uid": "search-input", "value": "character"},
-])
-
-# Click submit button
-click(uid="search-button")
-
-# Wait for results
-wait_for(text="Results", timeout=5000)
-
-# Verify results via snapshot
-snapshot = take_snapshot()
-```
-
-### Pattern: Modal Dialog Interaction
-
-```python
-# Open modal (e.g., add LoRA)
-click(uid="add-lora-button")
-
-# Wait for modal to appear
-wait_for(text="Add LoRA", timeout=3000)
-
-# Fill modal form
-fill_form(elements=[
-    {"uid": "lora-name", "value": "Test LoRA"},
-    {"uid": "lora-path", "value": "/path/to/lora.safetensors"},
-])
-
-# Submit
-click(uid="modal-submit-button")
-
-# Wait for success message or close
-wait_for(text="Success", timeout=5000)
-```
-
-## Available Scripts
-
-### scripts/start_server.py
-
-Starts or restarts the LoRa Manager standalone server.
+Server restart after config/fixture changes:

 ```bash
-python scripts/start_server.py [--port PORT] [--restart] [--wait]
+python .agents/skills/lora-manager-e2e/scripts/start_server.py \
+  --port {PORT} --settings-path <sandbox>/settings --restart --wait --detach
+# then reload the browser page (ignoreCache=True)
 ```

-Options:
- `--port`: Server port (default: 8188)
- `--restart`: Kill existing server before starting
- `--wait`: Wait for server to be ready before exiting
+`--restart` only kills the E2E server the script itself started (via its pidfile) and
+aborts instead of killing unrelated processes on the port.

-### scripts/wait_for_server.py
+## Abort Rule

-Polls server until ready or timeout.
+A sandboxed E2E should finish in well under 30 minutes. If any phase exceeds ~2x its
+expected duration (server readiness > 60 s, MCP connect > 2 min, a single scenario >
+10 min), or any single tool call fails 3+ times in a row, **STOP** — do not retry
+blindly. Report `BLOCKED` with the phase, last observed state (server PID,
+`ss -tlnp` output, page snapshot, last API response) and suspected cause. A clean
+BLOCKED report beats an hour of retries.

-```bash
-python scripts/wait_for_server.py [--port PORT] [--timeout SECONDS]
-```
+## Troubleshooting

-## Test Scenarios Reference
-
-See [references/test-scenarios.md](references/test-scenarios.md) for detailed test scenarios including:
- LoRA list display and filtering
- Model metadata editing
- Recipe creation and management
- Settings configuration
- Import/export functionality
-
-## Network Request Verification
-
-Use `list_network_requests` and `get_network_request` to verify API calls:
-
-```python
-# List recent XHR/fetch requests
-requests = list_network_requests(resourceTypes=["xhr", "fetch"])
-
-# Get details of specific request
-details = get_network_request(reqid=123)
-```
-
-## Console Message Monitoring
-
-```python
-# Check for errors or warnings
-messages = list_console_messages(types=["error", "warn"])
-```
-
-## Performance Testing
-
-```python
-# Start performance trace
-performance_start_trace(reload=True, autoStop=False)
-
-# Perform actions...
-
-# Stop and analyze
-results = performance_stop_trace()
-```
+- **"browser is already running" / `list_pages` fails**: a stale Chrome holds the
+  profile dir. Find it (`ps -ef | grep -i '[c]hrome.*user-data-dir'`), confirm it is a
+  leftover QA Chrome (not the live ComfyUI, not your current MCP browser), kill only
+  that PID, then retry `list_pages`.
+- **MCP refuses to write screenshots into the worktree**: save to `/tmp` via
+  `take_screenshot(filePath="/tmp/...")` and copy into the evidence dir from the shell.

 ## Cleanup

-Always ensure proper cleanup after tests:
-1. Stop the standalone server
-2. Close browser pages (keep at least one open)
-3. Clear temporary data if needed
+1. Stop the standalone server: `kill <recorded-pid>` (only the PID you started), then
+   confirm `ss -tlnp | grep ':{PORT}'` is empty.
+2. Close browser pages (keep at least one open).
+3. `rm -rf <sandbox>`; verify `<repo-root>` gained no `settings.json` or `cache/`.
+4. Re-run the real-data protection check from the SANDBOX section and record the result.

+## Troubleshooting
+
+### Stale profile lock ("browser is already running" / `list_pages` fails)
+
+A Chrome profile held by a stale Chrome from a prior MCP session makes `list_pages`
+fail with "browser is already running". Fix:
+
+1. Find the stale Chrome that owns the profile dir (e.g. `~/.config/chrome-dev-profile`):
+   ```bash
+   ps -ef | grep -i '[c]hrome.*user-data-dir'
+   ```
+2. Confirm it is a QA Chrome from a completed task (NOT the live ComfyUI server, NOT
+   your current MCP instance).
+3. Kill ONLY that stale Chrome (`kill <stale-pid>`), then retry `list_pages`.
+
+### Screenshot-write restrictions
+
+The MCP may refuse to write into paths outside its configured workspace roots
+(e.g. `.omo/evidence/screenshots/` under a worktree that canonicalizes to an unmapped
+path). Save the screenshot to `/tmp` via the MCP, then copy it into the evidence dir:
+
+```bash
+# MCP:  take_screenshot(filePath="/tmp/<plan>-e2e/recipe-b-after.png", format="png")
+# Shell:
+mkdir -p <repo-root>/.omo/evidence/screenshots
+cp /tmp/<plan>-e2e/recipe-b-after.png <repo-root>/.omo/evidence/screenshots/
+```
+
+### Time budgets & abort rule
+
+See SKILL.md "Time Budgets & Abort Guidance": if a phase exceeds ~2x its budget or a
+tool call retries 3+ times in a row, STOP and report BLOCKED with the last observed
+state (server PID + `ss -tlnp`, page snapshot, last API response). Do not loop.

+# Recipe Rematch/Repair E2E — Fixtures, Fresh State, Known Gaps
+
+Specialized guidance for recipe rematch/repair E2E runs, extracted from the SKILL.md
+main flow. Read the SKILL.md SANDBOX section first — everything here assumes a
+sandboxed run.
+
+## Fixture Rules (validated by the task-8 E2E)
+
+Seed the **sandboxed** `recipes_path` with hand-written fixture recipes:
+
+1. **Filename constraint**: each file MUST be named `f"{id}.recipe.json"` **and** the
+   in-JSON `id` field MUST equal the filename. Discovery accepts any `*.recipe.json`,
+   but persistence resolves the path via `get_recipe_json_path` and
+   `_save_recipe_persistently` returns `False` on a mismatch → the fixture would be
+   counted as an error.
+   - `recipe-a.recipe.json` → in-JSON `"id": "recipe-a"`
+2. **File format**: mirror an existing recipe JSON — top-level `id`, `file_path`,
+   `title`, `loras`, `fingerprint`, `gen_params`; lora entries per the persistence
+   conventions (`hash`, `file_name`, `modelVersionId`, `isDeleted`, ...).
+3. **Companion image**: each recipe needs an image (e.g. a `.webp` generated with PIL)
+   referenced by `file_path`, used for EXIF verification
+   (`ExifUtils.append_recipe_metadata` writes a `"Recipe metadata: ..."` marker; a
+   freshly generated `.webp` with no marker is the clean "untouched" control).
+4. **autov3 three-state contract**: for L3 (autov3-only, renamed-file) fixtures the
+   local model's `.metadata.json` sidecar MUST have the `autov3` key **ABSENT** (the
+   "unchecked" state), NOT `""` — `""` is the TERMINAL "checked but unavailable" state
+   that L3 deliberately skips. The scanner computes + persists `autov3` from the file
+   header during the normal library scan (`model_scanner.py` `_process_model_file`), so
+   the live L3 match resolves through the local autov3/hash cache; the
+   computed-autov3 branch for unchecked items is covered by the unit suite.
+5. **Fixture design for a rematch run** (mirrors the task-8 E2E):
+   - `recipe-a`: lora entry `isDeleted=True`, `hash` = 12-char autov3 computed from the
+     local model (`calculate_autov3`, `py/utils/file_utils.py`), whose local model file
+     was RENAMED after the recipe was written so `file_name` differs (proves L3 match
+     without filename).
+   - `recipe-b`: parser-convention checkpoint entry (uses `id`, no `modelVersionId`)
+     matching a local checkpoint via L2 — the local checkpoint's `.metadata.json` MUST
+     carry civitai version data with that `id` so `version_index` contains it (L2
+     cannot match otherwise).
+   - `recipe-c`: healthy recipe (no deleted entries) → must remain untouched.
+
+The scanner computes and persists model hashes during the library scan, so the sandbox
+model dirs just need the model files + `.metadata.json` sidecars. With
+`--settings-path`, all derived data lands under the sandbox settings dir (`cache/`,
+`backups/`, `logs/`, `stats/`, `wildcards/`), and NO `cache/` appears in the repo root.
+
+## Fresh State Between Entry-Point Runs
+
+Each entry point (global / per-recipe / selection-bulk) must start from the same
+deleted state. Between runs (keep a pristine copy in `<sandbox>/recipes-before/`):
+
+```bash
+# 1. Reset fixtures to the before-state snapshot
+cp <sandbox>/recipes-before/*.recipe.json <sandbox>/recipes/
+# 2. Clear the recipe/FTS caches (with --settings-path these live under the sandbox
+#    settings dir, NOT <repo-root>/cache)
+rm -f <sandbox>/settings/cache/recipe/*.sqlite
+rm -rf <sandbox>/settings/cache/fts/*
+# 3. Restart the server (fresh process, fresh scan)
+python .agents/skills/lora-manager-e2e/scripts/start_server.py \
+  --port {PORT} --settings-path <sandbox>/settings --restart --wait --timeout 30 --detach
+# 4. Re-verify the server is listening + reload the browser page
+```
+
+## Cancellation Testing (KNOWN GAP)
+
+Testing the rematch-cancel path E2E requires a run long enough to cancel mid-flight. A
+tiny 3-recipe fixture set completes in **seconds** — too fast to reliably cancel. The
+cancel path is currently **unit-covered only** (`rematch_all_recipes` cancellation
+tests); do not block an E2E run on cancel-path verification. If you must attempt it,
+you would need an artificially large/deferred fixture set to create a cancellable
+window — treat this as a research task, not part of the standard E2E.

+name: lora-manager-runtime-context
+description: Inspect ComfyUI LoRA Manager runtime configuration and local diagnostic state. Use when debugging LoRA Manager issues that require locating or reading settings.json, active library paths, model metadata JSON sidecars, recipe metadata JSON files, example image folders, SQLite caches, symlink maps, download history, aria2 state, or other cache files under the LoRA Manager user config directory.
+---
+
+# LoRA Manager Runtime Context
+
+## Core Rules
+
+- Treat runtime state as local user data. Prefer read-only inspection unless the user explicitly asks for mutation.
+- Never print secret-like settings values. Redact keys containing `key`, `token`, `secret`, `password`, `auth`, or `credential`, including `civitai_api_key`.
+- Resolve paths from the runtime configuration before guessing. Settings-directory precedence (highest first):
+  1. **Explicit override** — env `LORA_MANAGER_SETTINGS_DIR` or standalone `--settings-path` (also accepted by the inspect script as `--settings-path DIR`). Pins EVERYTHING (`settings.json`, `cache/`, `wildcards/`, `backups/`, `logs/`, `stats/`) under the given directory; bypasses portable mode and the user config dir. Common when inspecting a sandboxed/E2E instance.
+  2. **Portable** — repository `<repo-root>/settings.json` with `"use_portable_settings": true` (or `LORA_MANAGER_PORTABLE=1`): settings dir = `<repo-root>`.
+  3. **Default** — `~/.config/ComfyUI-LoRA-Manager` on this machine (`platformdirs.user_config_dir("ComfyUI-LoRA-Manager", appauthor=False)`).
+- Use the active library when selecting per-library caches and paths. Read `active_library` from settings; fall back to `default` if missing.
+- Normalize and expand `~` before comparing paths. Symlinks are common in this repo.
+
+## Quick Start
+
+Use the bundled helper for a safe first pass:
+
+```bash
+python .agents/skills/lora-manager-runtime-context/scripts/inspect_runtime_context.py summary
+python .agents/skills/lora-manager-runtime-context/scripts/inspect_runtime_context.py caches
+```
+
+The script redacts sensitive settings, opens SQLite databases read-only, and reports inaccessible or locked databases as warnings.
+
+For focused checks:
+
+```bash
+python .agents/skills/lora-manager-runtime-context/scripts/inspect_runtime_context.py recipes
+python .agents/skills/lora-manager-runtime-context/scripts/inspect_runtime_context.py model --path /path/to/model.safetensors
+python .agents/skills/lora-manager-runtime-context/scripts/inspect_runtime_context.py sqlite --db /path/to/cache.sqlite --limit 3
+```
+
+To inspect a sandboxed/E2E instance that pins its settings directory:
+
+```bash
+# --settings-path DIR (or LORA_MANAGER_SETTINGS_DIR) works with every subcommand:
+python .agents/skills/lora-manager-runtime-context/scripts/inspect_runtime_context.py \
+  --settings-path /tmp/opencode/<plan>-e2e/settings summary
+```
+
+## Runtime Path Rules
+
+- Settings directory: resolve via `py/utils/settings_paths.py` — `get_settings_dir()` honors the `LORA_MANAGER_SETTINGS_DIR` / programmatic override first, then portable mode, then `platformdirs.user_config_dir("ComfyUI-LoRA-Manager", appauthor=False)`. The inspect script mirrors this precedence in `resolve_settings_path()`.
+- Settings file: `<settings_dir>/settings.json`.
+- Cache root: `<settings_dir>/cache`.
+- Canonical cache files:
+  - Model cache: `cache/model/<active_library>.sqlite`.
+  - Recipe cache: `cache/recipe/<active_library>.sqlite`.
+  - Model update cache: `cache/model_update/<active_library>.sqlite`.
+  - Recipe FTS: `cache/fts/recipe_fts.sqlite`.
+  - Tag FTS: `cache/fts/tag_fts.sqlite`.
+  - Symlink map: `cache/symlink/symlink_map.json`.
+  - Download history: `cache/download_history/downloaded_versions.sqlite`.
+  - aria2 state: `cache/aria2/downloads.json`.
+- Legacy cache locations may exist; prefer canonical paths unless diagnosing migrations.
+
+## Data Location Rules
+
+- Model roots come from `settings.folder_paths` and the active library payload under `settings.libraries[active_library]`.
+- Model metadata JSON sidecars live next to the model file as `<model basename>.metadata.json`.
+- Recipes root is `settings.recipes_path` when it is a non-empty string. If empty, use the first configured LoRA root plus `/recipes`.
+- Recipe JSON files are named `*.recipe.json` under the recipes root and may be nested in folders.
+- Example image root is `settings.example_images_path`.
+- If multiple libraries are configured, example images are stored under `<example_images_path>/<sanitized_library>/<sha256>/`; otherwise they are under `<example_images_path>/<sha256>/`.
+
+## Useful Cache Tables
+
+- Model cache: `models`, `model_tags`, `hash_index`, `excluded_models`.
+- Recipe cache: `recipes`, `cache_metadata`.
+- Model update cache: `model_update_status`, `model_update_versions`.
+- Tag FTS cache: `tags`, `fts_metadata`, plus FTS internal tables.
+- Recipe FTS cache: `recipe_rowid`, `fts_metadata`, plus FTS internal tables.
+- Download history: `downloaded_model_versions`.
+
+Prefer querying only counts, schema, and a few sample rows unless the user asks for full output.

-# Recipe Batch Import Feature Design
-
-## Overview
-Enable users to import multiple images as recipes in a single operation, rather than processing them individually. This feature addresses the need for efficient bulk recipe creation from existing image collections.

-## API Endpoints
-
-| 端点 | 方法 | 说明 |
-|------|------|------|
-| `/api/lm/recipes/batch-import/start` | POST | 启动批量导入，返回 operation_id |
-| `/api/lm/recipes/batch-import/progress` | GET | 查询进度状态 |
-| `/api/lm/recipes/batch-import/cancel` | POST | 取消导入 |
-
-## Backend Implementation Details
-
-### BatchImportService
-
-Location: `py/services/batch_import_service.py`
-
-Key classes:
- `BatchImportItem`: Dataclass for individual import item
- `BatchImportProgress`: Dataclass for tracking progress
- `BatchImportService`: Main service class
-
-Features:
- Adaptive concurrency control (adjusts based on success/failure rate)
- WebSocket progress broadcasting
- Graceful error handling (individual failures don't stop the batch)
- Result aggregation
-
-### WebSocket Message Format
-
-```json
-{
-    "type": "batch_import_progress",
-    "operation_id": "xxx",
-    "total": 50,
-    "completed": 23,
-    "success": 21,
-    "failed": 2,
-    "skipped": 0,
-    "current_item": "image_024.png",
-    "status": "running"
-}
-```
-
-### Input Types
-
-1. **URL List**: Array of URLs (http/https)
-2. **Local Paths**: Array of local file paths
-3. **Directory**: Path to directory with optional recursive flag
-
-### Error Handling
-
- Invalid URLs/paths: Skip and record error
- Download failures: Record error, continue
- Metadata extraction failures: Mark as "no metadata"
- Duplicate detection: Option to skip duplicates
-
-## Frontend Implementation Details (TODO)
-
-### UI Components
-
-1. **BatchImportModal**: Main modal with tabs for URLs/Directory input
-2. **ProgressDisplay**: Real-time progress bar and status
-3. **ResultsSummary**: Final results with success/failure breakdown
-
-### Adaptive Concurrency Controller
-
-```javascript
-class AdaptiveConcurrencyController {
-    constructor(options = {}) {
-        this.minConcurrency = options.minConcurrency || 1;
-        this.maxConcurrency = options.maxConcurrency || 5;
-        this.currentConcurrency = options.initialConcurrency || 3;
-    }
-
-    adjustConcurrency(taskDuration, success) {
-        if (success && taskDuration < 1000 && this.currentConcurrency < this.maxConcurrency) {
-            this.currentConcurrency = Math.min(this.currentConcurrency + 1, this.maxConcurrency);
-        }
-        if (!success || taskDuration > 10000) {
-            this.currentConcurrency = Math.max(this.currentConcurrency - 1, this.minConcurrency);
-        }
-        return this.currentConcurrency;
-    }

+## Components (topology ledger)
+<!-- Lock the SHAPE before depth. One row per top-level component that can succeed or fail independently. -->
+<!-- id | outcome (one line) | status: active|deferred | evidence path -->
+- backend staging module (stage/purge/undo + manifest + per-volume dir resolution) | new module, active | pending exploration: model_lifecycle_service.py delete_model / delete_model_artifacts
+- delete endpoints return batch_id (model/recipe/bulk/duplicates) | active | pending exploration: handlers + response shapes
+- undo-delete HTTP endpoint + route registration | active | pending exploration: route registrar pattern
+- purge scheduling (30s timer + startup sweep + opportunistic) | active | pending exploration: app on_startup hooks

+- confirm-modal friction (delay-activate + size display + cancel focus) | active | pending exploration: modal focus behavior
+- i18n keys + sync_translation_keys.py | active | known
+
+## Open assumptions (announced defaults)
+<!-- Record any default you adopt instead of asking, so the user can veto it at the gate. -->
+<!-- assumption | adopted default | rationale | reversible? -->
+- Undo window TTL = 30s | 30s balances space-freeing intent vs accident recovery | yes (constant)
+- Staging dir name: `.lm-pending-delete/` under each model root; recipes: `{settings_dir}/.lm-pending-delete/` | hidden, same-volume [updated 2026-08: same-volume is now guaranteed by sibling staging inside the model's own folder, not by the root location], consistent | yes
+- Staging failure falls back to existing hard delete | user intent is delete; staging is best-effort; hard delete likely fails identically under same conditions | yes
+- Purge on startup uses expires_at (not purge-all) so a <30s restart with live tab can still undo | robust, matches client-side timer | yes
+- Settings toggle label: "Delete permanently immediately (skip undo window)" | power users freeing space | yes
+- C-friction: delete button enabled after 1.5s + modal shows freed size; NO type-to-confirm (user vetoed) | user explicitly rejected type-to-confirm | n/a
+- Bulk/duplicates delete: one batch id for whole action, one undo restores all | simplest consistent semantics | yes
+
+## Findings (cited - path:lines)
+
+### Backend
+- `delete_model_artifacts` (py/services/model_lifecycle_service.py:19-48) = physical delete via os.remove; patterns: main file + `{name}.metadata.json` + PREVIEW_EXTENSIONS (py/utils/constants.py:22-37). ALSO called by ModelScanner.bulk_delete_models (py/services/model_scanner.py:2221) - single swap point covers bulk models.
+- `ModelLifecycleService.delete_model` (model_lifecycle_service.py:101-154): fetches `cached_entry` (111-116) - SNAPSHOT available for cache restore; after delete: cache.raw_data removal + resort + bump_cache_version (136-143), `_hash_index.remove_by_path` (145-146), `_sync_update_for_model` (148; update-service only, no recipe JSON rewrites - recipe refs are hash-based, re-resolve on restore), `_persist_current_cache` (150-152), returns `{"success": True, "deleted_files": [...]}` (154).
+- Handler `delete_model` (py/routes/handlers/model_handlers.py:478-492): POST /api/lm/{prefix}/delete; response passthrough; `_broadcast_models_changed()` (57-74) after success; 400 `{"success":false,"error"}`; 500 plain text.
+- Recipe delete: handler (recipe_handlers.py:1422-1438) DELETE /api/lm/recipe/{recipe_id} -> persistence_service.delete_recipe (py/services/recipes/persistence_service.py:193-209): os.remove(recipe_json_path) + os.remove(image_path) (204-206), recipe_scanner.remove_recipe (208), returns `{"success": true, "message": ...}`. PersistenceResult dataclass (20-25).
+- Bulk models: POST /api/lm/{prefix}/bulk-delete (model_route_registrar.py:39) -> handler (model_handlers.py:974-994) -> lifecycle_service.bulk_delete_models (model_lifecycle_service.py:308-318) -> scanner.bulk_delete_models (model_scanner.py:2181-2269) which calls delete_model_artifacts per file (2221) + `_batch_update_cache_for_deleted_models` (2271-2335); response `{"success","status","total_deleted","total_attempted","cache_updated","results"}` (2254-2269).
+- Bulk recipes: POST /api/lm/recipes/bulk-delete (recipe_route_registrar.py:50) -> handler (recipe_handlers.py:1554-1573) -> persistence_service.bulk_delete (persistence_service.py:439-482): per-id os.remove x2 (464-466), recipe_scanner.bulk_remove (472); response `{"success","deleted","failed","total_deleted","total_failed"}` (474-482).
+- Duplicates: NO dedicated delete endpoints (find-only: GET /api/lm/{prefix}/find-duplicates model_route_registrar.py:59, GET /api/lm/recipes/find-duplicates recipe_route_registrar.py:49). Duplicate deletion reuses bulk-delete endpoints.
+- Startup hooks: lora_manager.py:183-187 `app.on_startup.append(lambda app: cls._initialize_services())` (ComfyUI mode, app = PromptServer.instance.app at :78); standalone.py:370-374 same (StandaloneLoraManager.add_routes). Background tasks: `asyncio.create_task(name=...)` (lora_manager.py:224-239; recipe_handlers.py:793). Singleton+asyncio.Lock pattern: model_scanner.py:40-63.
+- Settings: DEFAULT_SETTINGS (py/services/settings_manager.py:57-119), `get(key, default)` (1390-1392), get_settings_manager() (2215-2228), reset_settings_manager() (2231). Typed-bool getter example: get_skip_previously_downloaded_model_versions (1253-1262). Handlers: base_model_routes.py:70, base_recipe_routes.py:54.
+- Model roots: ModelScanner.get_model_roots base NotImplementedError (model_scanner.py:1073-1075); impls lora_scanner.py:31-45, checkpoint_scanner.py:428-441, embedding_scanner.py:24-36. `_find_root_for_file(file_path)` (model_scanner.py:1108-1124) returns containing root - for per-root staging dir computation [updated 2026-08: staging no longer uses the containing root; batches are siblings inside the model's own folder]. Business-path rule (AGENTS.md): use os.path.abspath, never realpath, for staging/undo routing.
+- Cache restore methods: ModelCache has raw_data + resort (conftest mocks: tests/conftest.py:144-154); ModelHashIndex.add_entry(sha256, file_path, autov3) (py/services/model_hash_index.py:16); RecipeScanner.add_recipe(recipe_data) (recipe_scanner.py:2136) -> recipe_cache.add_recipe (recipe_cache.py:64). No single-file incremental model rescan - use snapshot restore instead of rescan.
+- Route registrar: model_route_registrar.py:177 add_route(method, path, handler), :180 add_prefixed_route - undo endpoint can be a non-prefixed route via add_route.
+- Tests: tests/services/test_model_lifecycle_service.py (inline tmp_path files, per-test stub scanners ScannerForDelete/VersionAwareScanner etc); conftest MockScanner/MockCache/MockHashIndex (tests/conftest.py:134-212); integration fixtures tests/integration/conftest.py; lifecycle hook tests tests/routes/test_lora_manager_lifecycle.py:177-178, tests/standalone/test_standalone_server.py:83-84.
+
+### Frontend
+- 5 delete call sites:
+  a) Single model: static/js/utils/modalUtils.js confirmDelete (27-42) -> getModelApiClient().deleteModel(path); ignores return.
+  b) Recipe single: static/js/components/RecipeCard.js confirmDeleteRecipe (405-449) - RAW fetch DELETE /api/lm/recipe/{id}, checks only response.ok, showToast toast.recipes.deletedSuccessfully, state.virtualScroller.removeItemByFilePath.
+  c) Bulk: static/js/managers/BulkManager.js confirmBulkDelete (633-672) -> getActiveApiClient() (134-142) -> bulkDeleteModels(filePaths); reads result.cancelled/success/deleted_count/error.
+  d) Recipe duplicates: static/js/components/DuplicatesManager.js confirmDeleteDuplicates (457-494) - RAW fetch POST /api/lm/recipes/bulk-delete, reads data.success/data.total_deleted, exitDuplicateMode().
+  e) Model duplicates: static/js/components/ModelDuplicatesManager.js confirmDeleteDuplicates (710-776) - RAW fetch POST /api/lm/{type}/bulk-delete, reads data.total_deleted, then resetAndReload(true) + find-duplicates re-check.
+  Bonus: static/js/components/shared/ModelVersionsTab.js:1136-1144 client.deleteModel (ignores return).
+- API clients: BaseModelApiClient.deleteModel (static/js/api/baseModelApi.js:184-216) returns true/false, shows its own toasts, does removeItemByFilePath inside; bulkDeleteModels (1591-1642) returns {success, deleted_count, failed_count, errors} or {success:false, cancelled:true}; RecipeSidebarApiClient.bulkDeleteModels (recipeApi.js:623-664) returns {success, deleted_count: total_deleted, ...}. Endpoint map apiConfig.js:56,64.
+- Toast: showToast(key, params={}, type='info', fallback=null) (static/js/utils/uiHelpers.js:136-193) - textContent only, NO action/button support; durations 2000/5000ms; CSS static/css/components/toast.css (.toast flex gap:12px - button can be added). Closest action pattern: bannerService.registerBanner actions array + onRegister (static/js/managers/BannerService.js; used uiHelpers.js:18-57).
+- i18n: locales/en.json delete keys (1303-1314 bulkDelete, 1945-1948 recipes, 1987-1991 models, 2124-2130 duplicates, 2166-2170 toast.api); t()/interpolate (static/js/i18n/index.js:193-248); translate wrapper (utils/i18nHelpers.js:13-23); sync script scripts/sync_translation_keys.py (en reference, [TODO: Translate] placeholders).
+- Refresh after undo: recipes -> window.recipeManager.loadRecipes(true) (recipes.js:359; used by FilterManager.js:752 etc) or refreshRecipes (recipeApi.js:308); models -> resetAndReload(true) from modelApiFactory (used by ModelDuplicatesManager.js:740).
+- Size for modal: card.dataset.file_size (ModelCard.js:467), formatFileSize (ModelModal.js:615).
+- Tests: tests/frontend/utils/uiHelpers.dom.test.js (toast), api/recipeApi.bulk.test.js, components/duplicatesManager.test.js, components/modelDuplicatesManager.test.js, pages/*Page.test.js, i18n tests tests/i18n/test_i18n.py.
+
+## Decisions (with rationale)
+
+1. Same-volume rename staging for model files (atomic, no copy cost for multi-GB files); cross-volume rename forbidden. [CORRECTED 2026-08: "same-volume because under the containing root" was only true for plain directories — nested symlinked subdirs could cross volumes. Superseded by sibling staging: `.lm-pending-delete/<batch_id>/` inside the deleted model's own folder makes stage/undo same-device by construction; see "Symlink fix (2026-08)" below.]
+2. Copy-to-global-staging for recipes (small files; avoids recipe JSON vs preview image cross-volume problem).
+3. Manifest JSON files are the only state - no DB changes. Manifest includes model cached_entry snapshot for exact cache restore (no rescan needed).
+4. Undo endpoint returns restored paths; expired batch -> 404-style error -> frontend 'undo expired' toast.
+5. Skip-undo setting honored server-side (no batch_id in response -> no undo toast client-side).
+6. Staging failure falls back to existing hard delete (best-effort undo, never blocks delete).
+7. Undo window TTL = 30s constant (PENDING_DELETE_TTL_SECONDS); startup sweep uses expires_at (survives restart; browser-tab timer survives).
+8. Purge triple-trigger: per-batch asyncio timer task + on_startup sweep + opportunistic purge at each stage/undo.
+9. Frontend: new showActionToast (keep showToast signature untouched; extract shared createToastElement/appendToast internals); undo click -> shared handleUndoDelete(batchId, refreshFn); full list refresh after undo (recipes: window.recipeManager.loadRecipes(true); models: resetAndReload(true)).
+10. C-friction wave (NO type-to-confirm - user vetoed): delete buttons delay-activate 1.5s after modal open, initial focus on Cancel, model delete modal gains "permanently deleted from disk" warning + file size display (card.dataset.file_size + formatFileSize).
+11. Model cache restore on undo: append snapshot to cache.raw_data (dedupe by file_path) + resort + bump_cache_version + _persist_current_cache + _hash_index.add_entry + _broadcast_models_changed. Recipe restore: copy back files + recipe_scanner.add_recipe(recipe_data loaded from restored JSON).
+
+### Symlink fix (2026-08)
+
+Post-execution addendum (plan `.omo/plans/undo-delete-symlink-fix.md`, commits 5fd4946b / 0c00ee22):
+
+12. Model staging moved from `<model_root>/.lm-pending-delete/<batch_id>/` to `<model_dir>/.lm-pending-delete/<batch_id>/` (sibling of the model artifacts, inside the deleted model's own folder). Stage/undo renames are same-device BY CONSTRUCTION — EXDEV is impossible even when the business path traverses nested symlinks to other volumes (the decision-1 "containing root" guarantee covered only plain directories). EXDEV remains possible only for cross-volume merges, which keep the batch_ids-array fallback. Accepted edge: deleting the model's whole FOLDER during the 30s window destroys that batch (undo returns 404). Batch discovery uses an in-memory registry (`_known_batch_dirs`) with a startup reconciliation scan (`purge_expired(scan_roots=True)`) covering restarts and crash leftovers. Recipe batches unchanged (copy-based settings-dir staging with the `_restore_file` EXDEV fallback).

+- independent (oracle): APPROVE — no blocking issues; all round-5 items fixed with working, tested solutions; no new race/data-loss/consistency defects
+- Deferred optional improvements (non-blocking, recorded for executor awareness; plan file left untouched to preserve the approved digest):
+  1. Tag-count asymmetry: single delete_model never decrements _tags_count (lifecycle 101-154), bulk does (scanner 2297-2303); undo re-increment is exact for bulk, over-counts for single until rescan (cosmetic, self-healing). Optional fix riding in todo 2: decrement tags in the single-delete path to mirror bulk.
+  2. Todo 5 factual nit: ModelCache.resort() already rebuilds the version index — explicit rebuild in undo is belt-and-braces, no action needed.
+  3. Todo 8 premise nit: ModelVersionsTab call ignores deleteModel's return entirely — nothing breaks, no adaptation needed.
+  4. Todo 3's pytest command includes test_model_lifecycle_service.py which todo 2 edits in the same wave — run that file's tests after todo 2 lands.
+  5. merge_batches with a missing/quarantined constituent id: any sane fallback (abort -> batch_ids, or skip missing) acceptable — files stay staged either way.

+# Embeddings Usage Tracking — Hybrid Approach (Plan C)
+
+> **Status**: Reference document for future implementation
+> **Current implementation**: Plan A (prompt text parsing only, see `usage_stats.py:_process_embeddings`)
+> **Next step**: Add Plan B as a supplement when edge-case coverage is needed
+
+## Problem
+
+Embeddings in ComfyUI are not loaded through dedicated ComfyUI nodes like LoRAs or
+Checkpoints. They are resolved during CLIP tokenization when the prompt text contains
+`embedding:<name>` syntax (see `comfy/sd1_clip.py:SDTokenizer.tokenize_with_weights`).
+
+This means the existing metadata_collector hook (which intercepts node execution via
+`_map_node_over_list`) cannot capture embeddings the same way it captures LoRAs and
+checkpoints — there is no "EmbeddingLoader" node to intercept.
+
+## Solution Architecture
+
+The hybrid approach combines **two complementary mechanisms** to capture embedding
+usage from all possible paths.

+
+## Plan B Detail — Monkey-patch `load_embed`
+
+### Target Function
+
+**`comfy.sd1_clip.load_embed(embedding_name, embedding_directory, embedding_size, embed_key=None)`**
+at line 415 of `sd1_clip.py`.
+
+This is the **single choke point** for all embedding file loads in ComfyUI. Every
+CLIP variant (SD1, SDXL, SD3, Flux) calls this same function.
+
+### Implementation Sketch
+
+```python
+# In metadata_collector/metadata_hook.py (or a new module)
+import comfy.sd1_clip as sd1_clip
+
+_original_load_embed = sd1_clip.load_embed
+
+def _patched_load_embed(embedding_name, embedding_directory, embedding_size, embed_key=None):
+    result = _original_load_embed(
+        embedding_name, embedding_directory, embedding_size, embed_key
+    )
+    if result is not None:
+        _record_embedding_usage(embedding_name)
+    return result
+
+sd1_clip.load_embed = _patched_load_embed
+```
+
+### Prompt ID Association
+
+The challenge is associating the `load_embed` call with the current `prompt_id`.
+Options:
+
+1. **Thread-local / contextvar**: Store current `prompt_id` in a `contextvars.ContextVar`
+   that the metadata_collector sets at the start of each prompt execution.
+
+2. **MetadataRegistry singleton**: The MetadataRegistry already has `current_prompt_id`.
+   The patch can read it directly since both run in the same thread.
+
+3. **Lazy aggregation**: Instead of associating with prompt_id at load time, collect
+   all loaded embedding names in a global set during execution, then flush to
+   UsageStats after the prompt completes.
+
+### Files to Patch
+
+| File | Function | Coverage |
+|------|----------|----------|
+| `comfy/sd1_clip.py:415` | `load_embed()` | Primary — SD1.x, SDXL, SD3, Flux |
+| `comfy/sdxl_clip.py` | Not needed (calls `sd1_clip.SDTokenizer`) | — |
+| `comfy/text_encoders/sd3_clip.py` | Not needed (calls `sd1_clip.SDTokenizer`) | — |
+| `comfy/text_encoders/flux.py` | Not needed (calls `sd1_clip.SDTokenizer`) | — |
+
+The SD1 tokenizer is the base class for all CLIP variants' tokenizers, so patching
+`load_embed` covers them all.
+
+### Edge Cases
+
+| Edge Case | Plan A | Plan B |
+|-----------|--------|--------|
+| `embedding:name` in CLIPTextEncode | ✅ | ✅ |
+| `embedding:name` in CLIPTextEncodeFlux | ✅ | ✅ |
+| `embedding:name` in PromptLM (LoRA Manager) | ✅ | ✅ |
+| `embedding:name` in WAS_Text_to_Conditioning | ✅ | ✅ |
+| Custom node that loads embedding programmatically | ❌ | ✅ |
+| Embedding loaded multiple times in same prompt | ✅ (dedup via set) | ✅ (dedup via set) |
+| Embedding file not found | N/A | ✅ (can log) |
+| Embedding dimension mismatch | N/A | ✅ (can log) |
+| Text encoder with non-standard tokenizer (LLaMA, T5...) | Partial | ✅ (if it calls load_embed) |
+
+## Migration Path: Standalone → Hybrid
+
+### Phase 1 — Plan A (当前状态)
+- Prompt text parsing only
+- No monkey-patching required
+- Covers all standard workflows
+
+### Phase 2 — Enable Plan B (未来工作)
+1. Add monkey-patch of `load_embed` in `metadata_collector/metadata_hook.py` (alongside
+   the existing `_map_node_over_list` hook)
+2. Collect loaded embedding names in a `set()` on the registry
+3. In `UsageStats._process_embeddings()`, merge the Plan A results (from prompt text)
+   with the Plan B results (from the patch)
+4. Add `prompt_data` field on MetadataRegistry to store loaded embeddings per prompt
+
+### Deduplication
+
+```python
+# Merge Plan A + Plan B results in _process_embeddings
+plan_a_names = extract_from_prompt_texts(prompts_data)
+plan_b_names = registry.get_loaded_embeddings(prompt_id)
+
+all_names = plan_a_names | plan_b_names
+```
+
+## Testing the Hybrid
+
+| Scenario | What to verify |
+|----------|---------------|
+| Standard `embedding:name` in prompt | Plan A captures it |
+| Embedding loaded by custom node script | Plan B captures it |
+| Both paths fire for same embedding | No double-counting (dedup) |
+| Embedding name resolves to hash | EmbeddingScanner.get_hash_by_filename works |
+| No embedding scanner available | Graceful skip, no crash |
+| Missing embedding file | Plan B logs warning, Plan A skips gracefully |
+| Empty prompt | No crash, no entries |
+| Standalone mode | Both plans disabled gracefully |
+
+## Key Files Reference
+
+| File | Role |
+|------|------|
+| `py/utils/usage_stats.py` | Core — `_process_embeddings()` for Plan A |
+| `py/metadata_collector/constants.py` | `EMBEDDINGS` category constant |
+| `py/metadata_collector/metadata_hook.py` | Future — monkey-patch for Plan B |
+| `py/services/embedding_scanner.py` | Hash resolution service |
+| `py/routes/stats_routes.py` | Already handles `usage_data.get('embeddings', {})` |
+| `comfy/sd1_clip.py` (ComfyUI) | `load_embed()` — Plan B target |

+## Code Style
+
+### Python
+
+#### Imports & Formatting

 - Use `from __future__ import annotations` for forward references
 - Group imports: standard library, third-party, local (blank line separated)
+- Use `TYPE_CHECKING` guard for type-checking-only imports
 - Absolute imports within `py/`: `from ..services import X`
 - PEP 8 with 4-space indentation, type hints required

-### Naming Conventions
+#### Naming Conventions

 - Files: `snake_case.py`, Classes: `PascalCase`, Functions/vars: `snake_case`
 - Constants: `UPPER_SNAKE_CASE`, Private: `_protected`, `__mangled`

-### Error Handling & Async
+#### Error Handling & Async

 - Use `logging.getLogger(__name__)`, define custom exceptions in `py/services/errors.py`
 - `async def` for I/O, `@pytest.mark.asyncio` for async tests
 - Singleton with `asyncio.Lock`: see `ModelScanner.get_instance()`
 - Return `aiohttp.web.json_response` or `web.Response`

-### Testing
+### JavaScript/TypeScript

- `pytest` with `--import-mode=importlib`
- Fixtures in `tests/conftest.py`, use `tmp_path_factory` for isolation
- Mark tests needing real paths: `@pytest.mark.no_settings_dir_isolation`
- Mock ComfyUI dependencies via conftest patterns

-### Imports & Modules
+#### Imports & Modules

 - ES modules: `import { app } from "../../scripts/app.js"` for ComfyUI
 - Vue: `import { ref, computed } from 'vue'`, type imports: `import type { Foo }`
 - Export named functions: `export function foo() {}`

-### Naming & Formatting
+#### Naming & Formatting

 - camelCase for functions/vars/props, PascalCase for classes
 - Constants: `UPPER_SNAKE_CASE`, Files: `snake_case.js` or `kebab-case.js`
 - 2-space indentation preferred (follow existing file conventions)
 - Vue Single File Components: `<script setup lang="ts">` preferred

-### Widget Development
+#### Widget Development

+- Prefer vanilla JS for `web/comfyui/` widgets; avoid framework dependencies (except the Vue widgets in `vue-widgets/`)
 - ComfyUI: `app.registerExtension()`, `node.addDOMWidget(name, type, element, options)`
 - Event handlers via `addEventListener` or widget callbacks
 - Shared utilities: `web/comfyui/utils.js`
+- Dual-mode rendering patterns (canvas vs Vue): see `docs/comfyui-dual-mode-widgets.md`

-### Vue Composables Pattern
+#### Vue Composables Pattern

 - Use composition API: `useXxxState(widget)`, return reactive refs and methods
 - Guard restoration loops with flag: `let isRestoring = false`
 - Build config from state: `const buildConfig = (): Config => { ... }`

-## Architecture Patterns
+## Architecture
+
+### Dual Mode Operation
+
+The system runs in two modes:
+- **ComfyUI plugin mode**: Integrates with ComfyUI's PromptServer, uses `folder_paths` for model discovery
+- **Standalone mode**: `standalone.py` mocks ComfyUI dependencies, reads paths from `settings.json`
+- Detection: `os.environ.get("LORA_MANAGER_STANDALONE", "0") == "1"`
+
+### Backend Entry Points
+
+- `__init__.py` — ComfyUI plugin entry: registers nodes via `NODE_CLASS_MAPPINGS`, sets `WEB_DIRECTORY`, calls `LoraManager.add_routes()`
+- `standalone.py` — Standalone server: mocks `folder_paths` and node modules, starts aiohttp server
+- `py/lora_manager.py` — Main `LoraManager` class that registers all HTTP routes

 ### Service Layer

 - `ServiceRegistry` singleton for DI, services use `get_instance()` classmethod
+- `BaseModelService` abstract base → `LoraService`, `CheckpointService`, `EmbeddingService`
+- `ModelScanner` base → `LoraScanner`, `CheckpointScanner`, `EmbeddingScanner` for file discovery with hash-based deduplication
+- `PersistentModelCache` (SQLite) for metadata persistence
+- `MetadataSyncService` — background sync from CivitAI/CivArchive APIs
+- `SettingsManager` — settings with schema migration support
+- `WebSocketManager` — real-time progress broadcasting
+- `ModelServiceFactory` — creates the right service for each model type
+- Use cases in `py/services/use_cases/` orchestrate complex business logic (auto-organize, bulk refresh, downloads)
 - Separate scanners (discovery) from services (business logic)
 - Handlers in `py/routes/handlers/` are pure functions with deps as params

 ### Model Types & Routes

- `BaseModelService` base for LoRA, Checkpoint, Embedding
- `ModelScanner` for file discovery, hash deduplication
- `PersistentModelCache` (SQLite) for persistence
- Route registrars: `ModelRouteRegistrar`, endpoints: `/loras/*`, `/checkpoints/*`, `/embeddings/*`
- WebSocket via `WebSocketManager` for real-time updates
+- API endpoints follow `/loras/*`, `/checkpoints/*`, `/embeddings/*` patterns
+- Route registrars organize endpoints by domain: `ModelRouteRegistrar`, `RecipeRouteRegistrar`, etc.
+- Request handlers in `py/routes/handlers/` implement route logic
+- All routes use aiohttp, return `web.json_response` or `web.Response`

 ### Recipe System

- Base: `py/recipes/base.py`, Enrichment: `RecipeEnrichmentService`
- Parsers: `py/recipes/parsers/`
+- Base: `py/recipes/base.py`, Enrichment: `RecipeEnrichmentService` in `py/recipes/enrichment.py`
+- Parsers: `py/recipes/parsers/` for PNG metadata, JSON, and workflow formats
+
+### Custom Nodes
+
+- Location: `py/nodes/`, all nodes registered in `__init__.py`
+- Each node class has a `NAME` class attribute used as key in `NODE_CLASS_MAPPINGS`
+- Standard ComfyUI node pattern: `INPUT_TYPES()` classmethod, `RETURN_TYPES`, `FUNCTION`
+
+### Configuration
+
+- `py/config.py` manages folder paths for models and handles symlink mappings
+- Auto-saves paths to `settings.json` in ComfyUI mode
+
+### Frontend UI Architecture
+
+#### 1. LoRA Manager Web UI
+- Location: `./static/` (JS/CSS) and `./templates/` (HTML)
+- Tech: Vanilla JS + CSS, served by the hosting server (ComfyUI app in plugin mode, `standalone.py` in standalone mode)
+- Tests: `tests/frontend/**/*.test.js` (vitest + jsdom)
+
+#### 2. ComfyUI Custom Node Widgets
+- Location: `./web/comfyui/` (Vanilla JS) + `./vue-widgets/` (Vue)
+- Primary styles: `./web/comfyui/lm_styles.css` (NOT `./static/css/`)
+- Vue widgets: Vue 3 + TypeScript + PrimeVue + vue-i18n, e.g. `LoraPoolWidget`, `LoraRandomizerWidget`, `LoraCyclerWidget`, `AutocompleteTextWidget`
+- Vue builds to `./web/comfyui/vue-widgets/`; auto-built on ComfyUI startup via `py/vue_widget_builder.py`, typecheck via `vue-tsc`
+- Widget registration: `app.registerExtension()` and `getCustomWidgets` hooks; `node.addDOMWidget(...)` embeds HTML in LiteGraph nodes
+- See `docs/dom_widget_dev_guide.md` for the DOMWidget development guide
+
+## Testing
+
+### Backend (pytest)
+
+- Config in `pytest.ini`: `--import-mode=importlib`, testpaths=`tests`
+- Fixtures in `tests/conftest.py` mock ComfyUI dependencies; use `tmp_path_factory` for isolation
+- Markers: `@pytest.mark.asyncio`, `@pytest.mark.no_settings_dir_isolation` (tests needing real settings paths)
+
+### Frontend (vitest)
+
+- Vanilla JS tests: `tests/frontend/**/*.test.js` with jsdom; setup in `tests/frontend/setup.js`
+- Vue widget tests: `vue-widgets/tests/**/*.test.ts` with jsdom + `@vue/test-utils`
+
+## Key Integration Points
+
+- **Settings:** Stored in the user config directory (via `platformdirs`) or portable mode (`"use_portable_settings": true`)
+- **CivitAI/CivArchive:** API clients for metadata sync and model downloads; CivitAI API key stored in settings
+- **Symlinks:** Config scans symlinks to map virtual→physical paths; fingerprinting prevents redundant rescans
+- **WebSocket:** Broadcasts real-time progress for downloads, scans, and metadata sync
+- **Model scanning flow:** Walk folders → compute hashes → deduplicate → extract safetensors metadata → cache in SQLite → background CivitAI sync → WebSocket broadcast

 ## Important Notes

 - ALWAYS use English for comments (per copilot-instructions.md)
- Dual mode: ComfyUI plugin (folder_paths) vs standalone (settings.json)
- Detection: `os.environ.get("LORA_MANAGER_STANDALONE", "0") == "1"`
 - Run `python scripts/sync_translation_keys.py` after adding UI strings to `locales/en.json`
- Symlinks require normalized paths
-
-## Git / Commit Messages
-
- Follow the style of recent repository commits when writing commit messages
- Prefer the repo's existing `feat(...)`, `fix(...)`, `chore:` style where applicable
- If the user has provided a GitHub issue link or issue ID for the task, mention that issue in the commit message, for example `(#871)`
- When unrelated local changes exist, stage and commit only the files relevant to the requested task
-
-## Frontend UI Architecture
-
-### 1. Standalone Web UI
- Location: `./static/` and `./templates/`
- Tech: Vanilla JS + CSS, served by standalone server
- Tests via npm in root directory
-
-### 2. ComfyUI Custom Node Widgets
- Location: `./web/comfyui/` (Vanilla JS) + `./vue-widgets/` (Vue)
- Primary styles: `./web/comfyui/lm_styles.css` (NOT `./static/css/`)
- Vue builds to `./web/comfyui/vue-widgets/`, typecheck via `vue-tsc`
+- Symlinks require normalized paths.
+  **Business paths vs real paths**: All stored paths and operation routing use the
+  original paths as they appear under configured model roots — symlinks are NOT
+  resolved. `os.path.realpath` is only for scanner dedup and the symlink cache.
+  Any path passed to `os.remove`/`os.rename`/`shutil.move` or validated by a
+  containment check MUST use the business path (i.e. `os.path.abspath`, not
+  `realpath`).

- **Location:** `static/` (JS/CSS) and `templates/` (HTML)
- **Tech:** Vanilla JS + CSS, served by standalone server
- **Structure:** `static/js/core.js` (shared), `loras.js`, `checkpoints.js`, `embeddings.js`, `recipes.js`, `statistics.js`
- **Tests:** `tests/frontend/**/*.test.js` (vitest + jsdom)
-
-#### 2. ComfyUI Custom Node Widgets
- **Vanilla JS widgets:** `web/comfyui/*.js` — ES modules extending ComfyUI's LiteGraph UI
-  - `loras_widget.js` / `loras_widget_events.js` — Main LoRA selection widget
-  - `autocomplete.js` — Trigger word and embedding autocomplete
-  - `preview_tooltip.js` — Model card preview tooltips
-  - `top_menu_extension.js` — "Launch LoRA Manager" menu item
-  - `utils.js` — Shared utilities and API helpers
-  - Widget styling in `web/comfyui/lm_styles.css` (NOT `static/css/`)
- **Vue widgets:** `vue-widgets/src/` → built to `web/comfyui/vue-widgets/`
-  - Vue 3 + TypeScript + PrimeVue + vue-i18n
-  - Vite build with CSS-injected-by-JS plugin
-  - Components: `LoraPoolWidget`, `LoraRandomizerWidget`, `LoraCyclerWidget`, `AutocompleteTextWidget`
-  - Auto-built on ComfyUI startup via `py/vue_widget_builder.py`
-  - Tests: `vue-widgets/tests/**/*.test.ts` (vitest)
-
-**Widget registration pattern:**
- Widgets use `app.registerExtension()` and `getCustomWidgets` hooks
- `node.addDOMWidget(name, type, element, options)` embeds HTML in LiteGraph nodes
- See `docs/dom_widget_dev_guide.md` for DOMWidget development guide
-
-## Code Style
-
-**Python:**
- PEP 8, 4-space indentation, English comments only
- Use `from __future__ import annotations` for forward references
- Use `TYPE_CHECKING` guard for type-checking-only imports
- Loggers via `logging.getLogger(__name__)`
- Custom exceptions in `py/services/errors.py`
- Async patterns: `async def` for I/O, `@pytest.mark.asyncio` for async tests
- Singleton pattern with class-level `asyncio.Lock` (see `ModelScanner.get_instance()`)
-
-**JavaScript:**
- ES modules, camelCase functions/variables, PascalCase classes
- Widget files use `*_widget.js` suffix
- Prefer vanilla JS for `web/comfyui/` widgets, avoid framework dependencies (except Vue widgets)
-
-## Testing
-
-**Backend (pytest):**
- Config in `pytest.ini`: `--import-mode=importlib`, testpaths=`tests`
- Fixtures in `tests/conftest.py` handle ComfyUI dependency mocking
- Markers: `@pytest.mark.asyncio`, `@pytest.mark.no_settings_dir_isolation`
- Uses `tmp_path_factory` for directory isolation
-

-
---
-
-## Privacy & Security
-
-I understand concerns around browser extensions and privacy, and I want to be fully transparent about how the **LM Civitai Extension** works:
-
- **Reviewed and Verified**  
-  This extension has been **manually reviewed and approved by the Chrome Web Store**. The Firefox version uses the **exact same code** (only the packaging format differs) and has passed **Mozilla’s Add-on review**.
-
- **Minimal Network Access**  
-  The only external server this extension connects to is:  
-  **`https://willmiao.shop`** — used solely for **license validation**.
-
-  It does **not collect, transmit, or store any personal or usage data**.  
-  No browsing history, no user IDs, no analytics, no hidden trackers.
-
- **Local-Only Model Detection**  
-  Model detection and LoRA Manager communication all happen **locally** within your browser, directly interacting with your local LoRA Manager backend.
-
-I value your trust and are committed to keeping your local setup private and secure. If you have any questions, feel free to reach out!
-

-
-## How to Use
-
-After installing the extension, you'll automatically receive a **7-day trial** to explore all features.
-
-When the extension is correctly installed and your license is valid:
-
- Open **Civitai**, and you'll see visual indicators added by the extension on model cards, showing:
-  - ✅ Models already present in your local library  
-  - ⬇️ A download button for models not in your library  
-
-Clicking the download button adds the corresponding model version to the download queue, waiting to be downloaded. You can set up to **5 models to download simultaneously**.

- **Models Page**  
- **Creator Profiles** — If the creator has set their models to be visible  
- **Recommended Resources** — On individual model pages  
-
-### Version Buttons on Model Pages
-
-On a specific model page, visual indicators also appear on version buttons, showing which versions are already in your local library.
-
-**Starting from v0.4.8**, model pages use a dedicated download button for better compatibility. When switching to a specific version by clicking a version button:
-
- The new **dedicated download button** directly triggers download via **LoRA Manager**
- The **original download button** remains unchanged for standard browser downloads

-
-### Hide Models Already in Library (Beta)
-
-**New in v0.4.8**: A new **Hide models already in library (Beta)** option makes it easier to focus on models you haven't added yet. It can be enabled from Settings, or toggled quickly using **Ctrl + Shift + H** (macOS: **Command + Shift + H**).
-
-### Resources on Image Pages — now shows in-library indicators for image resources plus one-click recipe import
-
- **One-Click Import Civitai Image as Recipe** — Import any Civitai image as a recipe with a single click in the Resources Used panel.
- **Auto-Queue Missing Assets** — In Settings you can decide if LoRAs or checkpoints referenced by that image should automatically be added to your download queue.
- **More Accurate Metadata** — Importing directly from the page is faster than copying inside LM and keeps on-site tags and other metadata perfectly aligned.

-## Model Download Location & LoRA Manager Settings
-
-To use the **one-click download function**, you must first set:
-
- Your **Default LoRAs Root**  
- Your **Default Checkpoints Root**  
-
-These are set within LoRA Manager's settings.
-
-When everything is configured, downloaded model files will be placed in:  
-
-`<Default_Models_Root>/<Base_Model_of_the_Model>/<First_Tag_of_the_Model>`
-
-
-### Update: Default Path Customization (2025-07-21)  
-
-A new setting to customize the default download path has been added in the nightly version. You can now personalize where models are saved when downloading via the LM Civitai Extension.
-
-![Default Path Customization](https://github.com/willmiao/ComfyUI-Lora-Manager/blob/main/wiki-images/default-path-customization.png)
-
-The previous YAML path mapping file will be deprecated—settings will now be unified in settings.json to simplify configuration.
-
---
-
-## Backend Port Configuration
-
-If your **ComfyUI** or **LoRA Manager** backend is running on a port **other than the default 8188**, you must configure the backend port in the extension's settings.
-
-After correctly setting and saving the port, you'll see in the extension's header area:  
- A **Healthy** status with the tooltip:  `Connected to LoRA Manager on port xxxx`
-
-
---
-
-## Advanced Usage
-
-### Connecting to a Remote LoRA Manager
-
-If your LoRA Manager is running on another computer, you can still connect from your browser using port forwarding.
-
-> **Why can't you set a remote IP directly?**
->
-> For privacy and security, the extension only requests access to `http://127.0.0.1/*`. Supporting remote IPs would require much broader permissions, which may be rejected by browser stores and could raise user concerns.
-
-**Solution: Port Forwarding with `socat`**
-
-On your browser computer, run:
-
-`socat TCP-LISTEN:8188,bind=127.0.0.1,fork TCP:REMOTE.IP.ADDRESS.HERE:8188`
-
- Replace `REMOTE.IP.ADDRESS.HERE` with the IP of the machine running LoRA Manager.
- Adjust the port if needed.
-
-This lets the extension connect to `127.0.0.1:8188` as usual, with traffic forwarded to your remote server.
-
-_Thanks to user **Temikus** for sharing this solution!_
-
---
-
-## Roadmap
-
-The extension will evolve alongside **LoRA Manager** improvements. Planned features include:
-
- [x] Support for **additional model types** (e.g., embeddings)
- [x] One-click **Recipe Import**
- [x] Display of in-library status for all resources in the **Resources Used** section of the image page
- [x] One-click **Auto-organize Models**
- [x] **Hide models already in library (Beta)** - Focus on models you haven't added yet
-
-**Stay tuned — and thank you for your support!**

+# Agent Skills System
+
+The LoRA Manager agent skills system enables LLM-powered metadata enrichment and other AI-driven tasks. Users configure their own LLM provider (BYOK), and skills are executed through right-click context menu actions.
+

+```
+
+### Key Design Principle
+
+**Skills define *what* to do (prompt + post-processing). The AgentService handles *how* (LLM calls, validation, progress).**
+
+Skills never call the LLM directly. This keeps BYOK configuration centralized and provider-agnostic.
+
+## BYOK Configuration
+
+Users configure their LLM provider in **Settings → AI Provider**:
+
+| Setting | Description | Example |
+|---|---|---|
+| `llm_provider` | Provider type | `openai`, `ollama`, or `custom` |
+| `llm_api_key` | API key (not needed for local Ollama) | `sk-...` |
+| `llm_api_base` | Custom API base URL (empty = provider default) | `https://api.openai.com/v1` |
+| `llm_model` | Model name | `gpt-4o-mini` |
+
+Environment variable overrides: `LLM_API_KEY`, `LLM_MODEL`, `LLM_API_BASE`, `LLM_PROVIDER`.
+
+### Supported Providers
+
+- **OpenAI**: Uses `https://api.openai.com/v1` by default
+- **Ollama** (local): Uses `http://localhost:11434/v1`, no API key required
+- **Custom**: Any OpenAI-compatible endpoint (vLLM, LM Studio, etc.) — set `llm_api_base` explicitly
+
+## Available Skills
+
+### enrich_hf_metadata
+
+Enriches HuggingFace-downloaded models with metadata extracted by an LLM from the HF model card.
+
+**Entry point**: Right-click context menu → "Enrich Metadata (Agent)"
+
+**What it does**:
+1. Reads the model's `.metadata.json` to get the `hf_url`
+2. Fetches the README.md from the HuggingFace repository
+3. Sends the README + local metadata to the LLM for structured extraction
+4. Writes extracted fields to `.metadata.json`:
+   - `base_model` — only if current value is empty
+   - `trainedWords` — trigger words (LoRA only, if none exist)
+   - `modelDescription` — concise summary (if none exists)
+   - `tags` — merged with existing tags, deduplicated
+   - `metadata_source` — audit trail: `agent:enrich_hf_metadata`
+   - `llm_enriched_at` — ISO timestamp
+5. Downloads and optimizes preview image (if LLM found one in the README)
+6. Updates the scanner cache
+7. Broadcasts WebSocket progress events
+
+**Model types**: LoRA, Checkpoint, Embedding
+
+## Adding a New Skill
+
+### 1. Create the skill directory
+
+```
+py/services/agent/skills/<skill_name>/
+├── skill.yaml      # Skill metadata and schemas
+├── prompt.md       # LLM prompt template
+└── handler.py      # Pre-processing and post-processing
+```
+
+### 2. Write skill.yaml
+
+```yaml
+name: my_skill
+title: "My Skill"
+description: "What this skill does"
+llm_required: true
+model_type_filter: ["lora"]  # or null for all types
+input_schema:
+  type: object
+  properties:
+    model_paths:
+      type: array
+      items:
+        type: string
+  required:
+    - model_paths
+output_schema:
+  type: object
+  properties:
+    # ... JSON schema for LLM output
+permissions:
+  write_metadata: true
+  write_previews: false
+  network_domains:
+    - "example.com"
+```
+
+### 3. Write prompt.md
+
+Use `{{variable}}` placeholders that will be replaced with data from the `prepare` function:
+
+```markdown
+You are an expert assistant...
+
+Model URL: {{hf_url}}
+README content:
+{{readme_content}}
+
+Current metadata:
+{{current_metadata}}
+```
+
+### 4. Write handler.py
+
+```python
+async def prepare(model_path: str, input_data: dict) -> dict:
+    """Gather context for the LLM prompt. Returns variables for template rendering."""
+    return {
+        "model_path": model_path,
+        # ... other variables used in prompt.md
+    }
+
+async def post_process(context) -> dict:
+    """Apply the LLM-extracted data to the model."""
+    llm_response = context.llm_response
+    # ... write metadata, download previews, update cache
+    return {
+        "success": True,
+        "updated_fields": ["base_model", "tags"],
+        "errors": [],
+    }
+```
+
+**Important**: Use absolute imports (`from py.utils.metadata_manager import MetadataManager`) because skills are loaded via `importlib.util.spec_from_file_location`, which doesn't support relative imports.
+
+### 5. Test
+
+The skill is automatically discovered by `SkillRegistry` on startup. Test with:
+
+```python
+pytest tests/services/test_agent_service.py
+```
+
+## API Endpoints
+
+| Method | Path | Description |
+|---|---|---|
+| GET | `/api/lm/agent/skills` | List available skills |
+| POST | `/api/lm/agent/execute/{skill_name}` | Execute a skill (body: `{"model_paths": [...]}`) |
+| POST | `/api/lm/agent/cancel` | Cancel running skill (stub) |
+
+## WebSocket Events
+
+| Type | When | Key fields |
+|---|---|---|
+| `agent_progress` | Skill started/processing | `skill`, `status`, `total`, `processed`, `success`, `current_path` |
+| `agent_progress` | Skill completed | `skill`, `status`, `updated_models`, `errors`, `summary` |
+| `agent_progress` | Skill error | `skill`, `status`, `error` |
+
+## Security Model
+
+Skills declare permissions in `skill.yaml`:
+- `write_metadata` — can write `.metadata.json` files
+- `write_previews` — can download/replace preview images
+- `network_domains` — allowed domains for HTTP requests
+
+These are declarative constraints checked by `AgentService`. They are defense-in-depth, not a sandbox — the Python process can technically do anything, but the contract is clear and auditable.

+# ComfyUI Dual-Mode Widget Rendering
+
+ComfyUI custom node widgets render in one of two modes. Patterns that work in one often fail silently in the other. Test both.
+
+## Mode Detection
+
+```js
+typeof LiteGraph !== 'undefined' && LiteGraph.vueNodesMode
+```
+
+In Vue SFCs, `window.LiteGraph` is unavailable — pass as a prop from `main.ts`.
+
+## Canvas Mode Layout
+
+Uses `computeLayoutSize()` + `distributeSpace()` to allocate widget height within the node. Widgets with `computeLayoutSize` participate in space distribution; those with `computeSize` have fixed height.
+
+- `getMinHeight()` in `addDOMWidget` options → minimum widget height
+- `widget.computeLayoutSize()` → `{ minHeight, minWidth, maxHeight? }`
+- Avoid `getMaxHeight()` unless the widget genuinely needs a fixed cap (prevents user resize)
+
+## Vue Mode Layout
+
+Uses CSS Grid (`grid-template-rows`) + `ResizeObserver`. The ResizeObserver watches the widget's DOM and feeds back into grid row sizing. This creates a feedback loop: content grows → row resizes → more space for content → content reflows/grows → row resizes again.
+
+### Height Containment
+
+The fix: `contain: layout size` on the widget root. This tells the browser the element's intrinsic size is CSS-determined, not driven by descendant content. The ResizeObserver sees a stable size and the loop is broken.
+
+```css
+.widget-root.lm-vue-node {
+  height: 100%;
+  min-height: var(--comfy-widget-min-height, 200px);
+  contain: layout size;
+}
+```
+
+Existing examples: `.lm-loras-container.lm-vue-node` and `.comfy-tags-container.lm-vue-node` in `web/comfyui/lm_styles.css`.
+
+**Do NOT** fix height issues with `maxHeight`, `getMaxHeight()`, or inline `max-height` — these prevent the user from resizing the node.
+
+## Scroll Wheel Isolation
+
+Both modes need to distinguish "user wants to scroll widget content" from "user wants to zoom canvas".
+
+**Canvas mode:** Add `@wheel` on widget root. Check `event.target.closest(selector)` for scrollable sub-areas. If scrollable → `event.stopPropagation()`. Otherwise → `app.canvas.processMouseWheel(event)`.
+
+**Vue mode:** Add CSS class `lm-wheel-scrollable` to scrollable elements. The global capture-phase hook in `web/comfyui/utils.js` (`enableListWheelScroll`) detects wheel events on marked elements and manually scrolls them via `element.scrollTop`, consuming the event before canvas zoom sees it.
+
+## DOM Structure
+
+`main.ts` creates an outer `<div>` container, then `vueApp.mount(container)`. The Vue app renders its own root element inside.
+
+- `container.id` / `container.style.*` → outer element
+- Vue scoped `<style>` → `[data-v-hash]` applies only to Vue root
+
+Classes needed by scoped Vue CSS must go on the Vue root element. Pass data as props and bind with `:class` rather than manipulating the DOM from `main.ts`.
+
+## Serialization
+
+For stateful widgets that need workflow persistence:
+
+- `serialize: true` in `addDOMWidget` options
+- `serializeValue()` → state snapshot (called on workflow save)
+- `onSetValue(v)` → restore state (called on workflow load)
+- Always handle missing keys in restored value for backward compatibility with old workflows

+# i18n Translation Guidelines
+
+This document is the canonical set of conventions for translating LoRA Manager UI strings.
+It applies to **human translators and AI agents** alike. Read it before editing anything in
+`locales/`.
+
+Source of truth: `locales/en.json` (10 locales, 1810 leaf keys; all locales share the exact
+same key structure).
+
+Locales: `en`, `zh-CN`, `zh-TW`, `ja`, `ko`, `fr`, `de`, `es`, `ru`, `he` (RTL).
+
+> **Status (2026-08 sweep):** a full audit was executed and the terminology, placeholder,
+> stale-text, and untranslated-block fixes described in §2–§6 were applied across all locales
+> (commits `3c3ac49f` … `fd1227d3`). The tables below are now the **normative target state**,
+> not a to-do list — future edits should preserve these renderings and only add what is new.
+
+---
+
+## 1. Hard rules (do not violate)
+
+### R1 — Key structure is sacred
+- Only `locales/en.json` may add/remove/rename keys. All other locales must keep the exact
+  same nested key set. `tests/i18n/test_i18n.py` enforces this.
+- When a new UI string is added to `en.json`, run
+  `python scripts/sync_translation_keys.py` (adds the missing keys to all locales with
+  placeholder copies), then translate the newly added keys in every locale.
+- Never reorder, re-indent, or reformat a locale file "for tidiness". The sync script
+  preserves formatting; manual reformatting creates noisy diffs.
+
+### R2 — Placeholders and HTML must be preserved verbatim
+- `{name}`-style placeholders must appear in the translation exactly as in `en.json`.
+  Do not invent placeholders the source string does not have — the caller may not pass them
+  (example bug: `zh-CN recipes.controls.import.downloadLocationPreview` added `{path}`; the
+  template renders this key with no parameters, so the literal text `{path}` shows in the UI).
+- `{{...}}` in a locale value is an escaped literal brace — keep it identical.
+- Keep embedded HTML tags (e.g. `<strong>...</strong>`, `<code>...</code>`) intact.
+  You may move the tag around the sentence if the target language needs different word order.
+
+### R3 — Never translate or transliterate these
+- Model types: **LoRA, Checkpoint, Embedding, Diffusion Model**
+- Products/brands: **LoRA Manager, ComfyUI, CivitAI, CivArchive, HuggingFace, Ko-fi**
+- Ecosystem names: **LyCORIS, DoRA**, trigger-adjacent jargon **Prompt, Workflow**
+  (these are used as-is in the target-language SD community; see §2 per-language policy)
+- Theme names: **Nord, Midnight, Monokai, Dracula, Solarized**
+
+### R4 — The "Recipe" convention (the most important domain term)
+Product intent: a *Recipe* records a **LoRA combination + generation parameters**
+(prompt, seed, sampler, …) that reproduces an image style. The metaphor is a **cooking
+recipe** — "follow it and you get a similar dish". It is **not** a menu, not a dish list,
+not a prescription.
+
+Decision per language — translate only into a word whose everyday primary meaning is a
+cooking recipe; where that word would mislead users, **keep the English "Recipe(s)"**:
+
+| Locale | Use | Never use |
+|---|---|---|
+| fr | **Recipe / Recipes** (keep English) | recette(s) — cooking reading is secondary and it was explicitly judged misleading |
+| zh-CN / zh-TW | 配方 | 食谱 (reads as "food cookbook") |
+| ja | レシピ | — (leftover English "Recipe" in `initialization.recipes.title` / `toast.recipes.recipeSaved` → translate) |
+| ko | 레시피 | — |
+| de | Rezept / Rezepte | — (cooking meaning dominant; prescription reading acceptable) |
+| es | receta / recetas | — (cooking meaning dominant) |
+| ru | рецепт / рецепты | — (leftover English "Recipe" in `initialization.recipes.title` / `toast.recipes.recipeSaved` → translate) |
+| he | מתכון / מתכונים | — (cooking meaning dominant) |
+
+Whatever the choice, **one concept = one noun within a locale**. Currently violated in:
+- `fr` — "Recipe" (~97 keys, incl. nav) mixed with "recette" (~58 keys)
+- `zh-CN` / `zh-TW` — 配方 (126/122 keys) mixed with 食谱 / 食譜 (14/17 keys, all in the
+  *rematch* flow: `globalContextMenu.rematchRecipes.*`, `toast.recipes.rematch*`)
+- `de` — "Rezept" (136 keys) mixed with leftover English "Recipe" (5 keys)
+- `ja` / `ru` — leftover English "Recipe" in `initialization.recipes.title` ("Recipe Manager
+  zu initialisieren" / «Инициализация Recipe Manager») and `toast.recipes.recipeSaved`
+
+### R5 — One term, one rendering (within each locale)
+Same source word must not be translated several ways in one file. Known offender areas
+(see §5 for the full fix list): recipe, Checkpoint, Embedding, prompt, base model, preset,
+workflow, hash, metadata, tags, bulk. Every locale currently mixes variants of at least one
+of these — pick the preferred form in the §2 tables and normalize.
+
+### R6 — Register consistency
+- `zh-CN` / `zh-TW`: pick 你 or 您 once. Do not mix (zh-CN has 44×你 + 5×您; zh-TW has
+  27×您 + 18×你).
+- `de`: pick "du" or "Sie" once (currently 143×Sie + ~7×du).
+- `es`: pick "tú" or "usted" once.
+
+### R7 — Punctuation per script
+- Full-width punctuation `：（）` is correct **only in CJK locales** (zh-CN, zh-TW, ja, ko).
+- Latin/Cyrillic/Hebrew locales must use ASCII `: ()` — full-width colons leaked in there
+  are machine-translation artifacts. Known: `fr toast.recipes.createError/createFailed`,
+  `es toast.recipes.createError/createFailed` (e.g. "…de la receta：" should be "…de la receta:").
+- `fr` apostrophes must be U+2019 `'` / ASCII `'`, never a straight double quote:
+  `fr header.filter.allowSellingGeneratedContentTooltip` currently reads
+  `vendre d"images` → fix to `d'images`. Do not mix `'` and `'` in one file (fr has 299 vs 15).
+- Ellipsis: use ASCII `...` (project style). Don't introduce `…`.
+- Keep the sentence-ending period/omission consistent with the source string where the
+  language allows it.
+- `he` is RTL: mix of Hebrew and Latin scripts is normal; keep Latin term ordering natural.
+
+### R8 — No untranslated English leftovers
+Full sentences left byte-identical to `en.json` are bugs (brand names and URL placeholders
+are the exception). Every locale has them; see §6 for the per-locale checklist.
+`[TODO: Translate]` placeholders are the sanctioned intermediate state during feature
+development (see §7) — do not "fix" them unless the feature owner asked for translations.
+
+### R9 — Mirror the source even when the source is wrong
+If `en.json` itself contains an inconsistency (e.g. the `Civitai` vs `CivitAI` casing split,
+or the `CivitArchive` typo in `modals.relinkCivitai.helpText.format4`), translate/transcribe
+it as-is in your locale and instead **fix the source** in `en.json` (then propagate by
+re-syncing and re-translating affected keys). Do not silently diverge in one locale only.
+
+---
+
+## 2. Per-language term maps
+
+Preferred rendering per term. "Fix" means the locale currently contains the wrong variant
+and must be normalized. `en` = keep the English word as-is.
+
+### fr
+
+| Term | Use | Fix |
+|---|---|---|
+| recipe | Recipe(s) | Replace all "recette(s)" (58 keys, e.g. `recipes.actions.deleteRecipeWithShortcut`, `toast.recipes.rematchComplete`) with "Recipe(s)" |
+| Checkpoint | Checkpoint | `statistics.modelTypes.checkpoint` = "Point de contrôle" → "Checkpoint" |
+| trigger words | mot(s)-clé(s) | unify: `modals.model.triggerWords.editWord` uses "mot déclencheur" — pick one |
+| prompt / negative prompt | Prompt / prompt négatif | — |
+| base model | modèle(s) de base | — |
+| preset | préréglage | unify: `modals.model.usageTips.addPresetParameter` "prédéfini", `toast.presets.restored` "par défaut" |
+| hash | hash | `conflictConfirm.message` "hachage" → "hash" |
+| tags | tags | `settings.sections.priorityTags` "Étiquettes" → "Tags" |
+| metadata | métadonnées | `loras.controls.refresh.fullTooltip` keeps English "metadata" |
+| duplicates | doublon(s) | unify with "dupliqué(e)s" |
+| bulk | groupé(e) | unify with "par lot / mode lot" variants |
+
+### de
+
+| Term | Use | Fix |
+|---|---|---|
+| recipe | Rezept/Rezepte | 5 leftover English "Recipe" keys → Rezept (e.g. `globalContextMenu.repairRecipes.label`, `toast.recipes.recipeSaved`) |
+| base model | pick Basis-Modell or Basismodell | currently 27× hyphenated vs 15× closed |
+| metadata | Metadaten | 4 keys use "Modelldaten" (`onboarding.steps.fetch.title/content`) → Metadaten |
+| bulk | pick Massen- or Sammelmodus | `loras.controls.bulk.action` = "Massen" reads as "crowds" — use "Massenbearbeitung"/"Mehrfachauswahl" |
+| register | Sie (formal) | 7 keys use "du/dein" (`settings.backup.managementHelp`, `modals.checkUpdates.message/tip`, `doctor.footer`, …) |
+
+### es
+
+| Term | Use | Fix |

+## 3. Cross-cutting confusion hot-spots (must-fix list)
+
+All items below were **resolved** in the 2026-08 sweep — treat them as a regression
+watch-list: do not reintroduce these renderings.
+
+1. **Checkpoint rendered as a literal security/road checkpoint** — fr, es, ru, he, zh-CN,
+   zh-TW all had 4–6 keys in the `statistics.*` domain reading as "control point"; reverted
+   to "Checkpoint".
+2. **"recipe" variants that break the one-noun rule** — fr "recette" → "Recipe", zh
+   食谱/食譜 → 配方, de/ja/ru leftover English "Recipe" translated.
+3. **ko `header.filter.tagLogicAny`** — was inverted ("모든 태그 일치 (OR)") and identical
+   to `tagLogicAll`; now "어느 하나의 태그와 일치 (OR)".
+4. **ja `modals.model.versions.actions.viewLocalTooltip`** — was the stale "近日対応予定"
+   ("coming soon"); all 9 locales now describe the actual action.
+5. **Stale help texts** — `settings.downloadSkipBaseModels.help`,
+   `settings.aiProvider.apiBaseHelp`, `settings.hideEarlyAccessUpdates.help` retranslated
+   in all locales to the current `en.json` wording.
+6. **en.json source bugs** (fixed in source, then mirrored):
+   - "Civitai" → "CivitAI" brand casing (values only; key names `relinkCivitai` etc. keep
+     their lowercase form and must not be renamed)
+   - `modals.relinkCivitai.helpText.format4` "CivitArchive" typo → "CivArchive"
+   - `zh-CN recipes.controls.import.downloadLocationPreview` invented `{path}` removed
+
+---
+
+## 4. Placeholder contract deviations (current)
+
+`{...}` token sets must match `en.json` per key. All deviations found in the 2026-08 sweep
+were fixed, with one *intentional* exception:
+
+**`toast.settings.mappingsUpdated`** — the caller passes a hardcoded English inflection
+(`plural: count !== 1 ? 's' : ''`). Languages that cannot build a plural by appending that
+`s` (zh-CN/zh-TW, ja, ko, de, ru, he) **drop `{plural}`** and render a count-friendly form
+(`({count})` or a measure word); fr and es keep it (`mappage{plural}`, `mapeo{plural}`).
+
+```python
+# keep a copy of this rule next to the key if it ever moves:
+#   fr/es:  "... ({count} mappage{plural})"
+#   de/ru/he: "... ({count})"
+#   zh-CN: "（{count} 条映射）" / zh-TW: "（{count} 個對應）" / ja: "（{count} マッピング）"
+```
+
+Do NOT add `{...}` tokens the source lacks (the caller will not supply them, and the literal
+text renders in the UI), and do NOT rename source tokens (`{typePlural}` stays `{typePlural}`).
+
+---
+
+## 5. One term, one rendering — offender matrix
+
+Cross-locale summary of §2 inconsistencies. "✓" = already consistent. All ✗ cells were
+resolved in the 2026-08 sweep; the row shows the single rendering now in force per locale.

+
+Watch: ja/ko keep the model-type names **Checkpoint/Embedding** and `Diffusion Model` in
+Latin (consistent with their model-type sections) — do not transliterate them as
+チェックポイント/체크포인트.
+
+---
+
+## 6. Untranslated English leftovers (status)
+
+Values byte-identical to `en.json` that are actual UI sentences are bugs (brand names and
+URL placeholders are the exception). As of the 2026-08 sweep, **all previously untranslated
+blocks are translated** in every locale: `recipes.batchImport.*` + `toast.recipes.batchImport*`
+(fr/de/es/ru/he/ja/ko), `banners.communitySupport.*`, `modals.model.license.*`,
+`globalContextMenu.fetchMissingLicenses.*`, the `doctor.*` issue/action/label subset,
+`toast.settings.libraryLoadFailed` / `libraryActivateFailed`, `toast.api.moveFailed`,
+`settings.extraFolderPaths.restartRequired`, `toast.recipes.recipeSaved`,
+`sidebar.dragDrop.moveUnsupported`, `checkpoints.modelTypes.diffusion_model`
+(ja/ko keep the English loanword), `initialization.recipes.title`.
+
+The only values that remain intentionally identical to `en.json` are non-translatable:
+URL/path placeholders (`https://…`, `C:/…`), numeric presets (`5 (1080p), 6 (2K), 8 (4K)`),
+example token lists (`character, concept, style(toon|toon_style)`), service/provider names
+(`CivitAI → CivArchive → Archive DB`), and the external playlist title
+(`help.updateVlogs.playlistTitle`, de: translated to "LoRA Manager-Update-Playlist").
+
+Rule for `uiHelpers.workflow.noPromptTargets`: the second line (`Mark as → Send Prompt
+Target`) quotes literal ComfyUI context-menu items — keep those menu labels in English in
+every locale because that is what the user actually sees in ComfyUI.
+
+License labels (`modals.model.license.*`): the restriction labels are now translated in all
+locales (the sibling `creditRequired` has always been translated).
+
+---
+
+## 7. Workflow for agents and translators
+
+### Adding a new UI string
+1. Add the key to `locales/en.json` only.
+2. Run `python scripts/sync_translation_keys.py` — it inserts the key into the other 9
+   locales (as a `[TODO: Translate]` placeholder) preserving formatting.
+3. **During feature development, stop here.** While the UI copy is still in flux, leave the
+   `[TODO: Translate]` placeholders as-is — translating churning strings into 9 locales is
+   wasted work. Placeholders are a normal intermediate state, not a bug.
+4. Once the wording is final and the feature owner explicitly asks for translations,
+   translate **all** pending `[TODO: Translate]` keys in every locale (not just the latest
+   feature's), applying §1–§3 (placeholders verbatim, Recipe rule, term maps, register).
+   Find pending keys with: `grep -c "TODO: Translate" locales/*.json`
+5. If the new string contains new terminology, extend §2 tables.
+
+### Fixing a translation bug
+1. Locate the key (dotted path) in the relevant locale file.
+2. Check the corresponding `en.json` value and the actual caller (grep `static/js` or
+   `web/comfyui` for the key) to learn which placeholders are passed.
+3. Fix trivially; for normalization sweeps (e.g. "recette" → "Recipe"), do it file-wide for
+   the offending keys only — do not touch unrelated lines.
+4. If the bug is in `en.json` itself (R9), fix the source first, then re-sync and update all
+   locales.
+
+### Verification
+```bash
+pytest tests/i18n/test_i18n.py     # key parity + JSON validity + JS key references
+python scripts/sync_translation_keys.py --dry-run   # shows which keys would change; add --verbose for per-key detail
+npm test                           # frontend tests incl. i18n helpers
+```
+
+`pytest tests/i18n` only checks structure. Quality conventions in this document are not
+machine-enforced — a human/agent review pass is required.

+# Plan: Multi-File Downloads Within a Single CivitAI Model Version
+
+**Issue:** [#1058 — Cannot download multiple file variants from the same model version](https://github.com/willmiao/ComfyUI-Lora-Manager/issues/1058)
+**Status:** v2 — revised after adversarial review (backend correctness + frontend/tests)
+**Scope:** CivitAI/CivArchive downloads of `lora`, `checkpoint`, `embedding` model types. HuggingFace downloads are out of scope (already per-file).
+
+> v2 changelog: incorporated 18 review findings. Key changes vs v1:
+> shared file resolver + `resolved_version_id` for the gate (R1); `file_params` normalization at API boundary (R2); D2 hash-matching rule fixed for empty-hash cases (R6/R7); D3 extended to re-point `version_index` on removal (R4); D4 replaced with a child table (R3); `delete_model_version` interaction documented (R5); `ModelVersionsTab` surface added to phase 2 (F6); phase-2 multi-file loop requires a reload-deferred download variant (F7); queue-retry `file_params=NULL` known issue recorded (R9); test-fixture gaps and revised estimates (F10).
+
+---
+
+## 1. Problem Statement
+
+A CivitAI model version can contain multiple downloadable weight files (e.g. fp16/fp32, safetensors/ckpt, different sizes). LoRA Manager already has a working file-selection pipeline (frontend file dialog → `fileParams` → backend file matching), but downloaded state is tracked at the **model-version** level. After any single file of a version is downloaded:
+
+1. The version is marked **In Library** and the file-selection entry point disappears.
+2. The backend rejects further download attempts for that version.
+
+There is no way to download the remaining files of the same version through LoRA Manager.
+
+## 2. Current State (verified against code; all references confirmed by review)
+
+### 2.1 Download gating — backend (`py/services/download_manager.py`)
+
+`_execute_original_download` enforces two version-level gates:
+
+- **Library gate, early** (lines 1157–1184, before metadata fetch, fires when `model_version_id` given) and **late** (lines 1350–1376, fires only when `model_version_id is None`): `scanner.check_model_version_exists(version_id)` across lora/checkpoint/embedding scanners → hard error `"Model version already exists in ... library"`.
+- **History gate** (lines 1238–1279): when `skip_previously_downloaded_model_versions` setting is on, `_has_been_downloaded(model_type, version_id)` → silent skip. History DB primary key is `(model_type, version_id)` (`py/services/downloaded_version_history_service.py:61`).
+
+File selection works: `file_params {id, type, format, size, fp}` is matched against `version_info.files` (lines 1498–1569), **but only under `if file_params and model_version_id:` (line 1499)** — with `model_id`-only requests the selection silently falls back to the primary file (1571–1619). `file_params` currently carries no file `name` or hash.
+
+### 2.2 Downloaded-state surfacing — backend (`py/routes/handlers/model_handlers.py`)
+
+`get_civitai_versions` (lines 2148–2188) sets per-version `existsLocally` via `cache.version_index.get(version_id)` (plus a single `localPath` from that entry) and `hasBeenDownloaded` via the history service. No per-file granularity.
+
+### 2.3 Frontend blockers (`static/js/managers/DownloadManager.js`)
+
+Three independent gates prevent re-entering the file dialog:
+
+1. **Line 598:** file-select badge rendered only when `modelFiles.length > 1 && !existsLocally`.
+2. **Lines 666–681 (`updateNextButtonState`):** Next button disabled with "Already in Library" when `currentVersion.existsLocally`.
+3. **Lines 784–787 (`proceedToLocation`):** toast + abort when `currentVersion.existsLocally`.
+
+The badge path (`confirmFileSelection` lines 737–759 → `proceedToLocationContent` → `startDownload` single mode → `executeDownloadWithProgress` → POST `file_params`, `static/js/api/baseModelApi.js:1236–1250`) has **zero** `existsLocally` guards (all 12 occurrences enumerated; none on this path; `import/DownloadManager.js` has none either). The `.exists-locally` CSS class is purely visual (`download-modal.css:496–499`). **Making the badge visible again is sufficient to unlock the flow** for phase 1.
+
+Post-download refresh is clean: the modal closes and `resetAndReload(true)` performs a full library refetch (`DownloadManager.js:1063`); dialog reopen resets state and refetches versions with no client-side cache. No same-session staleness.
+
+### 2.4 Local identity of the downloaded file
+
+`LoraMetadata/CheckpointMetadata/EmbeddingMetadata.from_civitai_info(version_info, file_info, ...)` (`py/utils/models.py:245–369`) persists:
+
+- `sha256` = `file_info.hashes.SHA256` (lowercased, defaults to `""`) — a stable per-file identity;
+- `civitai` = the full `version_info` payload (including the `files` list).
+
+Metadata refresh (`metadata_sync_service.py:104–105`) replaces the `civitai` blob wholesale but never overwrites top-level `sha256`; `verify_duplicate_hashes` (481–526) corrects it to the on-disk hash. Top-level-sha256 matching is refresh-robust.
+
+**Caveats (review R6/R7):**
+- SHA256 is not guaranteed: CivArchive's transform only sets `hashes` when source data carries it (`civarchive_client.py:185–189`); `from_civitai_info` defaults to `""`.
+- Name fallback is unreliable exactly when it matters: local `file_name` is extension-less (`models.py:264`) and `generate_unique_filename` rewrites it with a hash suffix on conflict (`download_manager.py:1125–1136`); checkpoints with `hash_status='pending'` keep empty sha256 until on-demand hashing (`model_scanner.py:1232–1240`).
+
+### 2.5 Version index collision (pre-existing hazard)
+
+`ModelCache.version_index` is single-valued (`model_cache.py:133`: `version_index[version_id] = item`). Two files of the same version in the library → second entry overwrites the first; `remove_from_version_index` (lines 151–181) drops the whole version key when the indexed entry is removed, even if a sibling file remains. ~10 read sites depend on this index (48 grep touch points total; readers include `recipe_scanner.py:2682–2726`, `recipe_format.py:37–40`, `misc_handlers.py:2440–2444`, `model_handlers.py`, `model_scanner.check_model_version_exists:2444`).
+
+Review correction (F3): bulk paths `remove_models` (`model_scanner.py:2376`) and `update_single_model_cache` (`:1689`) call `rebuild_version_index()` right after, so a sibling re-enters the index in those flows — the hazard is narrower than v1 stated, but direct `remove_from_version_index` callers (e.g. `model_scanner.py:1018`) still drop the key, and the user-visible artifact in phase 1 is real: `localPath` in the dialog flips to whichever file was indexed last.
+
+### 2.6 Entry points that send / don't send `file_params` (fully enumerated by review)
+
+**Send `file_params` (user-initiated dialog flows only):** `DownloadManager.js:1611–1639` (single mode). API surface accepting arbitrary JSON `file_params`: GET `/api/lm/download-model-get` (`model_handlers.py:1634–1686`), POST `/api/lm/downloads/queue/add` (`model_handlers.py:1799–1832`).
+
+**Never send `file_params` (keep version-level semantics):** batch download (`DownloadManager.js:1756–1766`; batch also filters out in-library versions at `:1648`), `downloadVersionWithDefaults` (`:1810–1830`), recipe import (`import/DownloadManager.js:269–276`), bulk missing-LoRA (`BulkMissingLoraDownloadManager.js:292–299`), `RecipeModal.js:1728–1736`, `ModelVersionsTab.js:1427`. `web/comfyui/` and `vue-widgets/src` contain **no** download triggers at all (grep-verified). `py/services/use_cases/` has only `download_model_use_case.py` (pass-through).
+
+### 2.7 Paths that do NOT need changes (verified)
+
+- **aria2 pause/resume** (`_resume_restored_aria2_download`, line 754+): resumes from persisted `resume_context`; never re-runs existence gates.
+- **`download_coordinator.py:90`**: pure pass-through of `file_params`.
+- **Update checker / plugin self-update** (`update_routes.py:496–501`): only closes the history DB handle.
+- **History delete semantics**: `mark_as_deleted` sets `is_deleted_override=1` and `has_been_downloaded` then returns False (`downloaded_version_history_service.py:276`) — LM-initiated deletes already reset the history skip.
+
+### 2.8 Related pre-existing issues (record, not necessarily fix)
+
+- **Queue retry drops file selection** (R9): `download_queue_service.retry_from_history` / `retry_all_failed` re-queue with `file_params=NULL` (`download_queue_service.py:705, 758`) although the queue table has a `file_params` column (`:43`) — a retried non-primary download silently reverts to the primary file. Fix alongside phase 1 (small: persist and reuse the column).
+- **`delete_model_version`** (`misc_handlers.py:2410–2487`): resolves the file via the single-valued `version_index` (2440–2444), deletes only that one file, and `mark_as_deleted` flags the **entire version** as deleted in history (2479) even when a sibling file remains in the library. See phase 2 item 6.1.5.
+
+## 3. Goals / Non-Goals
+
+**Goals**
+
+- G1: A user can download any not-yet-downloaded file of a version already partially in the library (issue repro steps 6–8).
+- G2: True duplicates stay blocked: downloading the *same* file of the same version twice is rejected.
+- G3: Per-file downloaded state visible in the file dialog; multiple files selectable and downloadable in one pass.
+- G4: No regression for version-level semantics relied on by batch download, recipe missing-LoRA detection, and `skip_previously_downloaded_model_versions`.
+
+**Non-Goals**
+
+- No change to recipe `inLibrary` semantics ("any file of the version present" remains sufficient).
+- No change to the update-checker (version-level comparison).
+- No primary-key rebuild of the history database.
+- HuggingFace download flow untouched.
+
+## 4. Design Decisions
+
+- **D1 — Explicit file selection bypasses the history gate, version-level gates stay for everyone else.** The history skip exists to dedupe automated flows. A user explicitly picking a file is unambiguous intent; the file-level library gate (G2) still prevents real duplicates. **Guard conditions use normalized truthiness** (see D1a). All confirmed `file_params` senders are user-initiated dialog flows (2.6), and LM-initiated deletes already reset history (2.7), so the bypass only affects "downloaded but not LM-deleted" versions with the setting on — intended.
+- **D1a — `file_params` normalization at the boundary (R2).** `download-model-get` and `downloads/queue/add` accept arbitrary JSON; `{}` is `not None` but falsy and would bypass gates while downloading the primary file. Normalize `file_params = file_params or None` in the coordinator/handlers, and treat the bypass as active only when a target file id is resolvable.
+- **D2 — File identity matching rule (R6/R7):** hash-compare **only when both sides are non-empty** (lowercase SHA256 equality); name-compare when either side is empty. Never let `"" == ""` match. Name fallback caveats from 2.4 apply (renamed files, pending checkpoint hashes) — acceptable residual risk, worst case is a blocked re-download the user can retry after hashing completes.
+- **D3 — Cache indexes: additive multi-index + removal re-pointing (R4).** Add `version_files_index: Dict[int, List[dict]]` maintained alongside `version_index` by the same add/remove/rebuild methods; existing readers of `version_index` untouched. Additionally fix `remove_from_version_index`: when the popped entry has a surviving sibling (per the multi-index), re-point `version_index[version_id]` to the sibling instead of dropping the key; same for the `model_id_index` descriptor. This closes the 2.5 hazard for existing readers (`check_model_version_exists`, `existsLocally`, recipe matching) without restructuring anything.
+- **D4 — Per-file history via a child table (R3).** v1's additive-column approach is structurally impossible on a `(model_type, version_id)` PK (`ON CONFLICT DO UPDATE` would keep only the last file). Instead add `downloaded_version_files(model_type, version_id, file_id, file_name, downloaded_at, PRIMARY KEY(model_type, version_id, file_id))` — additive, no PK rebuild, honors the Non-Goal. Existing version-level table and queries unchanged. New per-file queries are opt-in. `_initialize_schema` uses `CREATE TABLE IF NOT EXISTS`, so the new table is created for existing DBs without any ALTER.
+- **D5 — UI flow reuse, with an extracted inner download function for multi-file (F7).** Phase 1 unlocks the existing badge → file dialog → location → download pipeline. Phase 2 upgrades the dialog to multi-select; iterating `executeDownloadWithProgress` as-is would produce N full library reloads, N toasts, and competing failure-summary modals — so phase 2 extracts a reload-deferred, failure-aggregating inner variant and runs one reload + one summary at the end.
+
+## 5. Implementation — Phase 1 (fix the issue; independently shippable)
+
+### 5.1 Backend — `py/services/download_manager.py`
+
+1. **Normalize `file_params`** at the boundary (D1a): `download_coordinator.schedule_download` and the two API handlers (`model_handlers.py:1649–1666`, `1810–1832`) apply `file_params = file_params or None`.
+2. **Extract a shared file resolver** (R1): pull the matching logic at 1498–1569 into `_resolve_target_file(version_info, file_params) -> Optional[dict]`, used by **both** the new gate and the download-selection path. The selection path's condition (line 1499) switches from `model_version_id` to `resolved_version_id` (already computed at 1230–1236 from `version_info.id`), so gate and download always agree on the target file — including the `model_id`-only case.
+3. **New helper** `_find_local_file_entry(version_id, target_file) -> Optional[dict]`: iterate the three scanners' cached `raw_data` (NOT `version_index` — single-valued); candidates = entries whose `civitai.id` normalizes to `version_id`; match per D2.
+4. **Gate restructure in `_execute_original_download`**:
+   - Early scanner gate (1157–1184): add `file_params is None` guard; with normalized `file_params`, defer (file identity not resolvable before metadata fetch).
+   - After `version_info` fetch + `resolved_version_id` (~1229): when `file_params` present, resolve target file via the shared resolver; unresolvable → hard error "No matching file" (fail closed, prevents empty-dict bypass). Resolvable → `_find_local_file_entry`; hit → same hard error shape as today with the file name in the message.
+   - History gate (1238–1279): add `file_params is None` (D1). Base-model skip (1281–1324) unchanged — still applies.
+   - Late gate (1350–1376): add `file_params is None` guard (F2) — the post-fetch file-level check above already covers this case.
+   - Nothing between the early gate and the post-fetch point assumes the version is absent (review task 6: only provider selection + metadata fetch; no DB writes; `_persist_aria2_state` runs only when actually downloading at 1659).
+5. **Queue retry fix** (2.8, small): persist `file_params` into the queue table on enqueue and reuse it in `retry_from_history` / `retry_all_failed`.
+6. Logging: `[download]` lines for file-level allow/block, consistent with existing style.
+
+**Estimated:** ~150–220 LOC + resolver extraction.
+
+### 5.2 Frontend — `static/js/managers/DownloadManager.js`
+
+1. Line 598: drop `&& !existsLocally` from the badge condition (badge shows whenever `modelFiles.length > 1`).
+2. `fileParams` construction (1611–1616): add `name: this.selectedFile.name`.
+3. Surface the backend "file already in library" hard error as a toast instead of only the batch-summary modal (R10/F12 nit; reuse existing error message field).
+4. No changes to `updateNextButtonState` / `proceedToLocation` in phase 1; no template or CSS changes.
+
+**Known phase-1 UX limitations (acknowledged, fixed in phase 2):** with all files downloaded the badge still renders and re-picking a downloaded file fails late (backend error after the location step); `localPath` may point at a sibling file; batch-preview "In Library" badge stays version-level and gives no hint of remaining files.
+
+**Estimated:** ~10–30 LOC (confirmed realistic by review).
+
+### 5.3 Phase 1 tests
+
+Backend — extend `tests/services/test_download_manager_basic.py` (1694 lines; all fixture patterns exist):
+
+- **Fixture gaps to add (F10):** `DummyScanner.get_cached_data()`/`raw_data` stub (~10 lines); `hashes.SHA256` in the metadata-provider payload's `files`.
+- Cases: same version + different SHA256 in library + `file_params` → proceeds; same SHA256 → hard error; `file_params=None` + version in library → hard error (unchanged); history-skip on + `file_params` → not skipped; without → skipped (unchanged); empty-dict `file_params` normalized → version-level behavior; `model_id`-only + `file_params` → gate and selection resolve the same file; legacy metadata (empty local sha256) matched by name; target file with empty SHA256 → name fallback, no `""==""` false positive.
+- Queue retry: `file_params` survives retry.
+- Assert proceed/abort via the existing `_execute_download` mock pattern.
+
+Frontend (`tests/frontend/`): badge renders for multi-file version with `existsLocally=true` (pattern from `downloadManager.history.test.js`).
+
+**Estimated:** ~150–250 LOC (confirmed realistic).
+
+## 6. Implementation — Phase 2 (per-file status + multi-select + index hardening)
+
+### 6.1 Backend
+
+1. **`py/services/model_cache.py`** (D3): add `version_files_index`; maintain in `add_to_version_index` / `remove_from_version_index` / `rebuild_version_index`; removal re-points `version_index[version_id]` (and the `model_id_index` descriptor) to a surviving sibling instead of dropping the key.
+2. **`py/services/model_scanner.py`**: expose `get_files_for_version(version_id) -> List[dict]`.
+3. **`py/routes/handlers/model_handlers.py` `get_civitai_versions`**: annotate each version with `downloadedFiles: [{fileId, fileName, filePath}]` via `version_files_index` + D2 matching against `version.files`.
+4. **`py/services/downloaded_version_history_service.py`** (D4): new child table `downloaded_version_files`; `mark_downloaded` also upserts the child row when `file_id` known; `mark_as_deleted` clears the version's child rows only when no sibling remains in the library; new `get_downloaded_file_ids(model_type, version_id) -> set[int]`. `_record_downloaded_version_history` passes `file_info` through.
+5. **`delete_model_version`** (`misc_handlers.py:2410–2487`, R5): resolve **all** local files of the version via `version_files_index`; delete all (current endpoint semantics are version-level) or — if kept per-file — only `mark_as_deleted` when no sibling remains. Decide at implementation time; minimum is documenting current behavior.
+6. **`ModelVersionsTab` backend support**: none needed beyond item 3 (`downloadedFiles`); the tab consumes the same versions payload.
+
+### 6.2 Frontend
+
+1. **File dialog multi-select** — change surface (F8): option markup (`DownloadManager.js:712–724`), the single-select click handler (`727–734`), the `input[type="radio"]:checked` selector in `confirmFileSelection` (`738`); template `templates/components/modals/download_modal.html:48–60` (confirm-button label only); CSS `download-modal.css` — checkbox variant of `.file-option-radio input` (595–604) and a **new** `.file-option.disabled` style (does not exist). Files whose id ∈ `downloadedFiles` render disabled with an "In Library" tag.
+2. **Mixed-type guard (F8):** multi-select is restricted to files sharing the same routing target (`_isDiffusionModel` is computed once from a single `selectedFile` at 798–803; e.g. "Model" + "UNet" files route to different roots). Disallow mixed-type multi-select (simplest, predictable); single-file selection unchanged.
+3. **Multi-file download loop (D5/F7):** extract from `executeDownloadWithProgress` a reload-deferred, no-toast inner function; iterate per selected file with per-file progress; one `resetAndReload(true)` + one aggregated success/failure summary at the end (reuse `showDownloadBatchSummary`).
+4. **`updateNextButtonState` / `proceedToLocation`:** for multi-file versions, Next routes into the file dialog; hard block only when *every* weight file is downloaded.
+5. **`ModelVersionsTab.js` (F6):** the Download action (`:576` hidden when `isInLibrary`) — for multi-file versions with remaining files, show it and route into the download modal's file dialog; keep hidden when all files present.
+6. **Batch preview (F5):** `batch-preview-local-badge` (`:1320`) gains a "partially downloaded" hint for multi-file versions with remaining files.
+7. New i18n keys (`modals.download.fileSelection.inLibrary`, `downloadSelected`, partial-download tooltip, etc.) → run `python scripts/sync_translation_keys.py`.
+
+### 6.3 Phase 2 tests
+
+- `model_cache` (`tests/services/test_model_cache.py` already covers add/remove at 44–55): multi-valued index; sibling re-point on removal; rebuild.
+- `get_civitai_versions`: `downloadedFiles` correctness (hash match, name fallback, no match, CivArchive no-hash payload).
+- History service (`tests/services/test_downloaded_version_history_service.py` uses real SQLite on tmp_path): child-table creation on a legacy DB; per-file record/query; `mark_as_deleted` sibling semantics.
+- Frontend: dialog checkbox rendering/disabled state and multi-file confirm — **greenfield behavior coverage** (F10: no existing test exercises `showFileSelectionStep`/`confirmFileSelection`; infra exists, patterns must be built).
+
+## 7. Risks and Mitigations
+
+| Risk | Impact | Mitigation |
+|---|---|---|
+| History-gate bypass (D1) causes unwanted re-downloads in automated flows | Large checkpoint files re-downloaded | Bypass only with normalized, resolvable `file_params` (D1a); all such senders are user-initiated dialog flows (2.6, verified); tests pin batch/recipe/bulk behavior. |
+| Empty-hash matching edge cases (R6) | Duplicate download of the same file, or false block | D2 rule: hash only when both non-empty; name otherwise; never `""==""`. Residual risk documented (2.4). |
+| Phase-1 late-failure UX (F12) | User picks a downloaded file, fails only after location step | Toast surfacing (5.2.3); phase 2 disables downloaded files up front. |
+| Phase-2 index change corrupts existing behavior | Recipe matching, delete flows | Additive index + re-point only; `version_index` read semantics unchanged; `remove_models`/`update_single_model_cache` already rebuild (F3); tests. |
+| `delete_model_version` marks whole version deleted while sibling remains (R5) | History wrongly suppresses re-download of the surviving sibling's version | Phase 2 item 6.1.5; documented until then. |
+| History child-table migration failure on user installs | Service init crash | `CREATE TABLE IF NOT EXISTS` in `_initialize_schema`; failure degrades to version-level behavior (per-file queries return empty). |
+| Batch-preview badge misleading for partial versions (F5) | Minor UX confusion | Acknowledged in phase 1; fixed in phase 2 item 6.2.6. |
+| UI confusion: version shows "In Library" while files remain downloadable | Support burden | Phase 2: per-file disabled state + partial-download tooltip. |
+| Hash-identical sibling files (repacked content) | Second file blocked | Acceptable: scanner hash dedup already collapses them. |
+
+## 8. Rollout
+
+1. **Commit 1** — `fix(download): allow downloading additional files of an in-library model version (#1058)` → Phase 1 (5.1–5.3).
+2. **Commit 2** — `feat(download): per-file download status and multi-file selection (#1058)` → Phase 2 (6.1–6.3).
+
+Phase 1 alone resolves the issue as reported; phase 2 can ship in a later release if review prefers smaller increments.
+
+## 9. Effort Estimate (revised after review)
+
+| Phase | Backend | Frontend | Tests | Risk |
+|---|---|---|---|---|
+| 1 | ~150–220 LOC (+ queue-retry fix ~30) | ~10–30 LOC | ~150–250 LOC | Low |

+# Plan: Global Rate-Limit Abidance for Recipe Ingest & Metadata Fetching
+
+**Issue:** [#1085 — Large Recipe Ingest Appears to not abide by vendor rate limits, possibly a few other errors?](https://github.com/willmiao/ComfyUI-Lora-Manager/issues/1085)
+**Status:** v2 — reviewed; decisions recorded in §10. **Phase 1 implemented**
+(2026-08-27, commit `c2a2048c`): coordinator + downloader gate + Fix C
+failover semantics + helper double-wait fix + settings. **Phase 2
+implemented** (2026-08-27): batch-import rate-limit failures map to
+`SKIPPED` + `rate_limited` WebSocket flag + UI slowdown hint (toast + status
+text, i18n keys synced); `download_to_memory` / `get_response_headers` /
+`download_file` register 429 cooldowns. Changes vs v1: Fix C moved to
+Phase 1, helper double-wait resolved in Phase 1, gate/guard ordering
+specified.
+**Scope:** HTTP API traffic to CivitAI (`civitai.red`) and CivArchive (`civarchive.com`) from metadata fetching (bulk refresh, metadata sync, recipe analysis/enrichment, usage-control lookups). Large binary downloads (model files / preview images via `download_file`) are out of scope for *pacing* (they are already single-connection transfers) but their 429 responses should still be *registered*.
+
+> Context: a first batch of fixes for this issue was already committed as
+> `ee233548` ("fix(recipes): enforce batch-import concurrency bound and harden
+> ingest errors (#1085)"): the batch-import concurrency controller now shares a
+> real semaphore (bounds 1–5 actually apply), the Comfy parser tolerates
+> list/`None` `ckpt_name`, CivArchive treats empty error payloads as failures,
+> and offline-cooldown short-circuits log at DEBUG. This plan covers the two
+> remaining orchestration-level fixes:
+> **Fix 2** — slow down globally when a vendor rate limit is hit (respect
+> `Retry-After`, queue instead of hammering); **Fix 3** — stop immediately
+> failing over to CivArchive when CivitAI is rate-limited.
+
+---
+
+## 1. Problem Statement
+
+During a large recipe ingest (e.g. importing the example-images directory,
+which can be thousands of images), the manager fires one metadata request per
+checkpoint + per LoRA per image through the fallback provider chain
+(`civitai_api → civarchive_api → sqlite`). Consequences observed in #1085:
+
+1. **CivitAI gets hammered** → 429s. The consumer then *immediately* tries
+   CivArchive for the same lookup, so **CivArchive gets hammered too** before
+   it was ever naturally needed (its only real job is recovering metadata for
+   models deleted from CivitAI).
+2. Requests are retried per-call after `Retry-After`, but **each concurrent
+   call sleeps independently** → thundering herd: thousands of coroutines wake
+   at the same moment and re-flood the vendor.
+3. While CivArchive is in the `ConnectivityGuard` cooldown, every batch item
+   short-circuits and is marked `FAILED` — the batch import's success/failure
+   accounting is polluted by a transient vendor state (log spam was fixed in
+   `ee233548`; the item-failure accounting is not).
+4. `ConnectivityGuard` (`py/services/connectivity_guard.py`) only treats
+   transport-level unreachability as offline; **HTTP 429 is invisible to it**,
+   so nothing ever intentionally paces request rate.
+
+User expectation from the issue: *"once a vendor rate limit time out is hit,
+you should trigger a slow down with intentional reduction in request rate"*.
+
+## 2. Current State (verified against code)
+
+### 2.1 Where 429s are surfaced
+
+- `Downloader.make_request` (`py/services/downloader.py:1120-1132`): HTTP 429 →
+  returns `RateLimitError(message, retry_after=…)` parsed from `Retry-After`
+  (missing header defaults to `None`).
+- `CivitaiClient._make_request` (`py/services/civitai_client.py:97-100`):
+  converts `RateLimitError` to a raise immediately; no waiting. Transient
+  5xx/connection errors are retried 3× with 1s/2s/4s backoff.
+- `CivArchiveClient._make_request` (`py/services/civarchive_client.py`):
+  raises `RateLimitError` with `provider="civarchive_api"` when not set.
+- `_RateLimitRetryHelper` (`py/services/model_metadata_provider.py:45-102`):
+  per-call retry loop — sleeps `retry_after` (capped at 1800 s; `≥120 s` ⇒ no
+  retry), then re-raises. Because every concurrent call runs its own helper,
+  they sleep in parallel and re-fire in parallel.
+- `FallbackMetadataProvider` (`py/services/model_metadata_provider.py:488-508,
+  564-584` etc.): on a final `RateLimitError` from one provider it logs
+  "skipping to next provider" and **continues to the next network provider** —
+  this is the direct cause of the CivArchive flood.
+- `MetadataSyncService.fetch_and_update_model`
+  (`py/services/metadata_sync_service.py:248-333`): manually iterates
+  `provider_attempts`; on `RateLimitError` it `continue`s to the next provider
+  (same failover problem), then reports `"Rate limited"` when nothing
+  succeeded.
+- `Downloader.make_request` has a per-destination scope already available:
+  `_guard_destination(url)` returns the hostname (`downloader.py:1194-1199`),
+  used by `ConnectivityGuard`.
+
+### 2.2 What pacing exists today
+
+- `ConnectivityGuard`: per-destination cooldown (30 s base, ×2 per extra
+  failure batch, 300 s cap) triggered only by transport errors
+  (`connectivity_guard.py:168-197`).
+- `AdaptiveConcurrencyController` (batch import, fixed in `ee233548`): shared
+  semaphore enforces 1–5 concurrent items; *duration*-based adjustment only —
+  it never sees HTTP statuses, so it cannot distinguish "slow because rate
+  limited" from "slow because big image".
+- No token bucket, no minimum inter-request interval, no shared
+  `Retry-After` gate anywhere (`grep` for throttle/token-bucket/rate-limiter:
+  0 hits).
+
+## 3. Requirements & Constraints
+
+R1. **Respect `Retry-After`.** After a 429, no further request to that
+    destination may be sent before the vendor's retry window elapses.
+R2. **No thundering herd.** Concurrent waiters must share one wake-up (gate),
+    not sleep independently.
+R3. **No double load.** A CivitAI 429 must not trigger a CivArchive request
+    for the same lookup. CivArchive should only be consulted when CivitAI
+    legitimately has no answer (404 / "not found"), or when CivitAI is
+    unreachable long-term.
+R4. **No spurious item failures.** A rate-limited request must not turn a
+    batch-import item into `FAILED`; it should wait (bounded) and retry, or at
+    worst be `SKIPPED` with a clear "rate limited" reason (re-runnable import).
+R5. **Never hang forever.** All waiting is bounded by a configurable cap; on
+    expiry the caller receives the `RateLimitError` and can decide.
+R6. **Keep legitimate failover.** Deleted-model recovery via CivArchive/sqlite
+    must keep working (404 paths unchanged).
+R7. **Single choke point.** The pacing gate should live where every API call
+    passes (the `Downloader`), so bulk refresh, metadata sync, recipe
+    analysis, and usage-control lookups all benefit without per-feature work.
+
+## 4. Approach Comparison
+
+### A. Reactive gate — shared `Retry-After` deadman clock (recommended core)
+
+A process-wide, per-destination coordinator records the *next-allowed-send*
+timestamp from each 429 (`now + max(retry_after, backoff)`). Every request
+through `Downloader.make_request` consults the gate *before sending* and *when
+a 429 arrives*; waiters block on a shared `asyncio.Event` that fires when the
+cooldown expires.
+
+- Pros: single choke point (R7); herd-free (R2); honors server guidance (R1);
+  no guessing at vendor limits; covers all providers automatically; reuses
+  existing per-destination scoping.
+- Cons: still experiences 429s before slowing down (reactive); long
+  `Retry-After` windows (CivArchive has been observed at ~1500 s) need a sane
+  wait cap + skip/retry UX.
+
+### B. Preemptive pacing — minimum inter-request interval (recommended companion)
+
+Per-destination token bucket (simplest form: capacity 1 — at least `N` seconds
+between consecutive API requests; `N` configurable, default ~0.75 s ≈ 80
+r/min ceiling).
+
+- Pros: prevents most 429s before they happen — exactly the "intentional
+  reduction in request rate" the issue asks for; trivial to implement on top
+  of A's coordinator.
+- Cons: adds latency to bulk operations (thousands of models × `N`); the *exact*
+  vendor limits are unknown (CivitAI anonymous vs keyed vs `civitai.red`
+  mirror differ), so the default must be conservative-but-not-crippling and
+  settings-tunable.
+
+### C. Fallback semantics change — stop network→network failover on 429 (must-do, low risk)
+
+`FallbackMetadataProvider` (and `MetadataSyncService.fetch_and_update_model`'s
+manual loop) must treat a final `RateLimitError` as a **terminal, non-failover
+result** for network providers. Local-only providers (sqlite archive DB) may
+stay as a last resort (no vendor cost).
+
+- Pros: directly removes the CivArchive flood; small, surgical change.
+- Cons: none significant; requires care to keep 404-failover intact (R6).
+
+### Rejected / deferred
+
+- **Per-feature retry queues** (batch import pauses & resumes whole batches):
+  richer UX but much larger change (batch state machine, WebSocket states);
+  unnecessary once A+B make requests wait at the choke point. Defer unless
+  review finds the bounded-wait UX insufficient.
+- **Full token bucket with burst credit**: overkill; capacity-1 interval is
+  enough given the shared semaphore already caps concurrency at 5.
+- **Retrying in `connectivity_guard`**: wrong layer — the guard is about
+  transport reachability, not vendor quota.
+
+## 5. Recommended Architecture
+
+New singleton **`RateLimitCoordinator`** (`py/services/rate_limit_coordinator.py`,
+mirroring `ConnectivityGuard`'s singleton + per-destination patterns):
+
+```
+state per destination (hostname):
+  next_allowed_send: float (monotonic)   # from 429 Retry-After + backoff
+  consecutive_429: int                   # for backoff growth
+  last_send_at: float                    # for min-interval pacing
+  waiters: list[Future] | asyncio.Event  # shared wake-up per cooldown cycle
+```
+
+API:
+
+- `async wait_for_slot(destination, request_started_within_window: bool)`
+  — called by `Downloader.make_request` *before* sending (blocks until
+  `min(now >= next_allowed_send)` and inter-request interval elapses) and
+  re-armable after a 429.
+- `register_rate_limit(destination, retry_after: float | None)`
+  — called on 429: `next_allowed_send = max(now + retry_after_or_backoff, current)`;
+  `consecutive_429 += 1`; backoff = `retry_after` honored, else exponential
+  `30 · 2^(n-1)` capped at 1800 s; creates/re-arms the shared wake-up event.
+- `register_success(destination)` — resets `consecutive_429` (called from the
+  existing 200 path in `make_request`).
+- `remaining_seconds(destination)`, `in_cooldown(destination)` — for tests and
+  diagnostics.
+
+Enforcement points:
+
+1. **`Downloader.make_request`** (`downloader.py:1102-1132`): ordering inside
+   the method is **connectivity-guard fail-fast first** (offline short-circuit
+   costs nothing to check), **then** `await coordinator.wait_for_slot(destination)`
+   before `session.request`. On 429: `coordinator.register_rate_limit(...)`,
+   then *wait for the gate and re-send* (loop, bounded by
+   `rate_limit_max_wait_seconds`, default 300; `retry_after ≥ cap` ⇒ fail
+   immediately). After the loop, return the `RateLimitError` to the caller
+   (unchanged contract) **with `exc.gate_handled = True` set** so downstream
+   retry helpers know the wait already happened. 200 path calls
+   `register_success`.
+2. **`Downloader.download_to_memory` / `get_response_headers`** (phase 2):
+   register 429s (so API calls queue); waiting only in `make_request`
+   initially.
+3. **`FallbackMetadataProvider`** (`model_metadata_provider.py`): remove
+   network→network failover on `RateLimitError` — re-raise; only sqlite stays
+   as a local last resort (implementation: per-method `except RateLimitError`
+   handler that marks the chain rate-limited and stops iterating).
+4. **`MetadataSyncService.fetch_and_update_model`**
+   (`metadata_sync_service.py:248-333`): on `RateLimitError` from the default
+   provider, stop appending further network providers (sqlite may remain);
+   the existing `any_rate_limited` merge already produces `"Rate limited"`.
+5. **Batch import** (`batch_import_service.py`): no structural change needed —
+   items now wait inside `make_request`; optionally (phase 2) map residual
+   rate-limit failures (after the wait cap) to `SKIPPED` with
+   `"rate limited (retry_after=…s); re-run the import later"` instead of
+   `FAILED`, and surface a `rate_limited` flag in the WebSocket progress
+   broadcast.
+6. **`_RateLimitRetryHelper` retries** (`model_metadata_provider.py`):
+   **Phase 1** — when the raised `RateLimitError` carries `gate_handled = True`
+   (set by the downloader after honoring the gate), the helper skips its own
+   `retry_after` sleep and re-raises immediately, eliminating the double wait.
+   The wiring stays so a `RateLimitError` still propagates cleanly; full
+   demotion/removal can follow once the gate proves out.
+
+Settings (`settings.json`, schema extension in `SettingsManager`):
+
+| key | default | meaning |
+|---|---|---|
+| `rate_limit_gate_enabled` | `true` | master switch for the coordinator |
+| `rate_limit_max_wait_seconds` | `300` | how long `make_request` waits on a 429 gate before returning the error |
+| `rate_limit_min_interval_seconds` | `0.75` | minimum seconds between API requests per destination (pacing, R6-friendly conservative default) |
+
+## 6. Changes by File
+
+| File | Change |
+|---|---|
+| `py/services/rate_limit_coordinator.py` (new) | coordinator singleton + per-destination state + tests seam |
+| `py/services/downloader.py` | gate pre-check + 429 register/wait/retry loop + `register_success`; log the 429 notice at INFO once per cooldown, then DEBUG |
+| `py/services/model_metadata_provider.py` | `FallbackMetadataProvider`: stop network failover on `RateLimitError`; helper skips its sleep when the error is marked `gate_handled` |
+| `py/services/metadata_sync_service.py` | `fetch_and_update_model`: same failover semantics; keep sqlite last resort |
+| `py/services/batch_import_service.py` | (phase 2) rate-limit failures → `SKIPPED` + `rate_limited` progress flag |
+| `py/services/settings_manager.py` | new settings keys + defaults |
+| `tests/services/test_rate_limit_coordinator.py` (new) | gate unit tests |
+| `tests/services/test_civitai_client.py` / `test_civarchive_client.py` | provider-level 429 behavior |
+| `tests/services/test_metadata_service.py` | failover-chain tests |
+| `tests/services/test_batch_import_service.py` | SKIPPED-on-rate-limit |
+
+## 7. Impact, Risks, Open Questions
+
+- **Behavior change**: with the gate in `make_request`, any request can block
+  up to the wait cap — UI actions that call the API (e.g. a model-details
+  fetch) may take longer during cooldowns. Mitigation: bounded cap + INFO log
+  + the existing async request handling already tolerates slow responses.
+  **Decided (§10): interactive requests take the same bounded wait** — one
+  behavior, no call-source plumbing; cooldowns are usually short.
+- **Gate waits occupy batch slots**: with the 1–5 batch semaphore, all slots
+  can park on a gate simultaneously, freezing visible progress for up to one
+  wait cap per wave. Bounded and acceptable; the phase-2 `SKIPPED` mapping +
+  WebSocket `rate_limited` flag (both confirmed in scope, §10) make the stall
+  visible and recoverable.
+- **Rate limit reality check**: CivitAI anonymous vs keyed limits, and whether
+  `civitai.red` differs, is unverified. Default pacing `0.75 s/req` is a
+  conservative guess (R6). Open question for maintainer: preferred default
+  and whether an API-keyed ceiling should be higher.
+- **Long CivArchive windows**: `Retry-After ~1500 s` observed in code
+  comments. **Decided (§10): keep the 300 s default cap** — such lookups
+  fail/skip rather than park a request path for 25 minutes; batch import maps
+  them to `SKIPPED` (phase 2) so the user can re-run later.
+- **Double waiting**: `_RateLimitRetryHelper` + gate could stack waits.
+  **Resolved in Phase 1**: the downloader marks gate-honored errors with
+  `gate_handled = True` and the helper skips its own sleep for those.
+- **Downloads**: `download_file` 429s return an error to download managers
+  unchanged (already handled); only *registration* is proposed, so future
+  API calls queue behind a large `Retry-After` from a download burst.
+
+## 8. Test Plan
+
+1. **Coordinator unit tests** (new file):
+   - 429 with `retry_after` → `wait_for_slot` blocks ~that long, then passes.
+   - N concurrent waiters all wake together (herd test, wall-clock ≈ one
+     window, not N windows).
+   - Consecutive 429s grow backoff; `register_success` resets.
+   - Missing `Retry-After` → default backoff path.
+   - Wait cap: request fails after `rate_limit_max_wait_seconds` with
+     `RateLimitError`.
+2. **Downloader tests** (mock aiohttp session): 429 then 200 → `make_request`
+   returns success after gate delay; two back-to-back calls to the same
+   destination are spaced ≥ `min_interval`; different destinations are not
+   spaced.
+3. **Provider tests**: `FallbackMetadataProvider.get_model_version_info` —
+   Civitai raises `RateLimitError` → CivArchive mock **not called**; 404 still
+   falls through to CivArchive; sqlite still tried after network 429.
+4. **Sync-service test**: `fetch_and_update_model` with a rate-limited default
+   provider → result error contains `"Rate limited"` and sqlite attempt state
+   unchanged.
+5. **Batch-import test**: analysis provider 429s first, then succeeds →
+   item ends `SUCCESS` (wait path), and post-cap 429 → `SKIPPED` with
+   rate-limit reason (phase 2).
+6. Full regression: `pytest tests/services tests/routes tests/standalone`
+   (currently 1582 passing).
+
+## 9. Implementation Phases
+
+- **Phase 1 (this plan, reviewed):** `RateLimitCoordinator` +
+  `Downloader.make_request` integration (guard fail-fast → gate pre-check
+  pacing → 429 register/wait/retry loop with cap → `gate_handled` marking) +
+  settings + **Fix C failover semantics** (`FallbackMetadataProvider`,
+  `fetch_and_update_model` — moved up from phase 2: smallest diff, kills the
+  CivArchive flood immediately, independent of coordinator correctness) +
+  `_RateLimitRetryHelper` double-wait fix + coordinator/downloader/provider/
+  sync tests.
+- **Phase 2:** batch-import `SKIPPED`-on-rate-limit + `rate_limited` WebSocket
+  progress flag + slowdown hint (confirmed, §10),
+  `download_to_memory`/HEAD 429 registration, batch tests.
+- **Phase 3:** full regression + docs + commit referencing `(#1085)`.
+
+## 10. Review Checklist — Decisions (2026-08-27)
+
+- [x] Default pacing interval `0.75 s` — **accepted** as conservative default;
+      tunable via `rate_limit_min_interval_seconds`. Revisit if CivitAI
+      publishes keyed/anonymous ceilings.
+- [x] Wait cap `300 s` — **accepted**; long-window CivArchive lookups fail →
+      batch import marks them `SKIPPED` with a rate-limit reason (phase 2).
+- [x] Interactive API calls also wait (bounded) — **yes**, same behavior for
+      all callers.
+- [x] Keep sqlite as last resort behind a network rate limit — **yes**
+      (local-only, no vendor cost).
+- [x] UI hint — **yes**: WebSocket `rate_limited` flag + "rate limited —
+      slowing down" hint in batch-import progress (phase 2); INFO logging
+      regardless.
