feat(other-models): announce the feature only when folders are available

Other Models management is opt-in and its folders come from
folder_paths.get_folder_paths(). In plugin mode ComfyUI registers vae,
upscale_models, text_encoders, clip_vision and controlnet out of the box, so
enabling the feature works immediately. Standalone only knows the keys present
in settings.json.folder_paths, and that file is edited by hand - there is no UI
for those keys - so a standalone user who followed the announcement banner
reached "Enable Other Models" and then an empty page.

Gate the announcement on the capability instead of on how the process was
started:

- Config.get_other_models_availability() probes every canonical other key
  (legacy clip collapses into text_encoders where the host exposes
  map_legacy) and reports which sub_types resolve to a folder that exists on
  disk. It deliberately ignores enable_other_models: the question is "could
  this work here at all?". An empty folder counts, because CivitAI downloads
  can target it.
- /api/lm/settings exposes it as the derived, non-persisted
  other_models_paths_available flag; a probe failure yields null and the
  banner fails open.
- BannerService only registers the announcement when the flag is not false.
  `=== false` (not falsy) keeps a cached/older payload working, and nothing is
  written to dismissed_banners, so the banner can return once folders exist.
- The Other page grows an "enabled but nothing to scan" empty state driven by
  config.other_roots, showing the settings.json snippet for standalone and a
  pointer to ComfyUI model paths otherwise, plus an Open Settings action. It
  also covers the corner where only a non-default sub_type has a folder.

Translate the six other.noPaths.* keys into all nine locales and record the
new "folder key" / "on disk" terminology in the i18n guidelines.

Backend tests and pytest tests/i18n could not run in this environment (no
pytest/platformdirs); the probe was exercised against a stubbed folder_paths.
Frontend: 120 files / 1101 JS tests passed.

-# LoRa Manager E2E Testing
-
-This skill provides workflows and utilities for end-to-end testing of LoRa Manager using Chrome DevTools MCP.
-
-## Conventions Used in This Document
-
-- **`{PORT}`**: The server port. The default candidate is `8188`, but **`8188` is commonly occupied by a live ComfyUI process** and MUST NOT be assumed to be free. Always check availability first (see [Port Selection](#port-selection)) and use a free port (e.g. `8199`) for the E2E run. Substitute the actual port for every `{PORT}` in the commands below.
-- **`<repo-root>`**: The repository/worktree root. Always run commands from the repo or worktree root; never assume a specific absolute path (paths such as `/home/<user>/...` differ per machine). The E2E scripts resolve the project root themselves, but fixture/settings paths are relative to `<repo-root>`.
-
-## SANDBOX (MANDATORY)
-
-> **Read this section before running anything.** Every E2E run MUST target a throwaway sandbox, never the real user data. A fresh subagent that skips this section WILL permanently mutate real user recipes.
-
-1. **Portable settings**: create `<repo-root>/settings.json` (gitignored) with `"use_portable_settings": true` plus sandboxed `folder_paths` (lora/checkpoint roots) and `recipes_path`. This keeps the configuration inside the repo instead of the real user config dir (`~/.config/ComfyUI-LoRA-Manager/settings.json`).
-2. **Sandboxed paths**: point `folder_paths` / `recipes_path` / `example_images_path` at disposable dirs — e.g. under `/tmp/opencode/<plan-name>-e2e/` (or worktree-local dirs). NEVER point the E2E at the real library (`~/models/...`), real recipe dir, or real settings.
-3. **Never touch the real config**: the real user config at `~/.config/ComfyUI-LoRA-Manager/settings.json` and the real recipe dir must remain byte-identical before and after the run.
-4. **Record real-data protection proof** before starting and after finishing:
-   ```bash
-   # BEFORE: snapshot real config + recipe library state
-   sha256sum ~/.config/ComfyUI-LoRA-Manager/settings.json > /tmp/opencode/<plan>-e2e/settings.before.sha256
-   ls ~/models/recipes/*.recipe.json 2>/dev/null | wc -l > /tmp/opencode/<plan>-e2e/recipes-count.before.txt
-   find ~/models/recipes -name '*.recipe.json' -newermt "$(date -Iseconds)" | head   # expect empty after run
-   # AFTER: record again, then diff the two snapshots. Any change = the run leaked into real data.
-   ```
-   Also confirm `<repo-root>/git status` stays clean for `settings.json`/`cache/` (both are gitignored).
-
-### Portable Settings Example
-
-```json
-{
-  "use_portable_settings": true,
-  "folder_paths": {
-    "loras": ["/tmp/opencode/<plan>-e2e/models/loras"],
-    "checkpoints": ["/tmp/opencode/<plan>-e2e/models/checkpoints"],
-    "unet": ["/tmp/opencode/<plan>-e2e/models/checkpoints"],
-    "diffusers": []
-  },
-  "recipes_path": "/tmp/opencode/<plan>-e2e/recipes",
-  "example_images_path": "/tmp/opencode/<plan>-e2e/example_images"
-}
-```
-
-The scanner computes and persists model hashes during the library scan, so the sandbox model dirs just need the model files + `.metadata.json` sidecars (see [Fixture + Fresh-State Guidance](#fixture--fresh-state-guidance)).
-
-## Time Budgets & Abort Guidance
-
-A fresh subagent should complete a sandboxed standalone E2E **in well under 30 minutes**. Budget each phase:
-
-| Phase | Expected duration | Abort if |
-| --- | --- | --- |
-| Port check + sandbox setup | < 2 min | — |
-| Server start (detached) + readiness | < 30 s | > 60 s (2x) → stop |
-| Chrome DevTools MCP connect | < 1 min | > 2 min → stop |
-| Per entry-point run (after fixtures ready) | < 5 min | > 10 min (2x) → stop |
-| Fixture reset + cache clear between runs | < 1 min | > 2 min → stop |
-
-**Abort rule**: if a phase exceeds ~2x its budget, OR any single tool call fails/retries 3+ times in a row, **STOP**. Do not loop or retry blindly. Report `BLOCKED` with: the phase, the last observed state (server PID + `ss -tlnp` output, page snapshot, last API response), and the suspected cause. Record the partial state as evidence; a clean BLOCKED report is more valuable than an hour of retries.
-
-## Prerequisites
-
-- LoRa Manager project cloned and dependencies installed (`pip install -r requirements.txt`) — run everything from `<repo-root>`
-- Chrome browser available for debugging
-- Chrome DevTools MCP connected
-- `ss` (or `lsof`/`netstat`) available for port checks: `ss -tlnp`
-
-## Port Selection
-
-`8188` is only the *default candidate*. Verify it is actually free before every run:
-
-```bash
-# Is anything listening on 8188?
-ss -tlnp | grep ':8188' || echo "8188 is free"
-```
-
-- If a process holds `8188` (e.g. a live ComfyUI — pid 6575 on this machine), pick a different free port, e.g. `8199`:
-  ```bash
-  ss -tlnp | grep ':8199' || echo "8199 is free"
-  ```
-- **Never** kill a process you did not start for this E2E. The live ComfyUI is off-limits. Pick a free port instead.
-- Use your chosen port for **all** subsequent commands (server, Chrome launch, browser URLs).
-
-## Quick Start Workflow (sandboxed)
-
-### 1. Prepare the sandbox
-
-```bash
-cd <repo-root>                       # ALWAYS run from the repo/worktree root
-mkdir -p /tmp/opencode/<plan>-e2e/models/{loras,checkpoints}
-mkdir -p /tmp/opencode/<plan>-e2e/{recipes,example_images,recipes-before}
-# write <repo-root>/settings.json per the portable-settings example above
-# record real-data protection proof (see SANDBOX section)
-```
-
-### 2. Check port availability
-
-```bash
-ss -tlnp | grep ':{PORT}' || echo "port {PORT} is free"
-```
-
-If `{PORT}` is occupied by an unrelated process, pick a free one and use it everywhere below. When in doubt use `8199`.
-
-### 3. Start LoRa Manager Standalone (detached)
-
-The standalone server **dies with the shell unless launched fully detached** — a plain background `&` from the bash tool is killed when the tool call returns. Launch via the helper script:
-
-```bash
-python .agents/skills/lora-manager-e2e/scripts/start_server.py --port {PORT} --wait --timeout 30 --detach
-```
-
-Or manually (equivalent detached form):
-
-```bash
-setsid nohup python standalone.py --port {PORT} --host 127.0.0.1 < /dev/null \
-  >> /tmp/opencode/<plan>-e2e/server.log 2>&1 &
-echo "started"   # record the printed/pidfile PID for cleanup
-```
-
-Verify it is listening **before** proceeding (readiness poll is not a substitute for this):
-
-```bash
-ss -tlnp | grep ':{PORT}'
-```
-
-Record the server PID for cleanup: the helper script writes it to `/tmp/lora-manager-e2e-server-{PORT}.pid`; a manual `setsid` launch has no pidfile, so capture it explicitly (e.g. from `ss -tlnp`).
-
-### 4. Open Chrome Debug Mode
-
-```bash
-# Chrome with remote debugging on port 9222 (note the {PORT} URL)
-google-chrome --remote-debugging-port=9222 --user-data-dir=/tmp/chrome-lora-manager http://127.0.0.1:{PORT}/loras
-```
-
-### 5. Connect Chrome DevTools MCP
-
-Ensure the MCP server is connected to Chrome at `http://localhost:9222`. Verify with `list_pages` — if it fails with "browser is already running", see [Chrome DevTools MCP Troubleshooting](#chrome-devtools-mcp-troubleshooting).
-
-### 6. 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:{PORT}/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.
-# --restart only kills the E2E server this script started before (via its pidfile);
-# it refuses to blindly kill unrelated processes on the port.
-python .agents/skills/lora-manager-e2e/scripts/start_server.py --port {PORT} --restart --wait --detach
-
-# 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)
-```
-
-## Fixture + Fresh-State Guidance
-
-For rematch/repair E2E runs, seed the **sandboxed** `recipes_path` with hand-written fixture recipes. Rules (validated by the task-8 E2E):
-
-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.
-
-### Fresh state between entry-point runs
-
-Each entry point (global / per-recipe / selection-bulk) must start from the same deleted state. Between runs:
-
-```bash
-# 1. Reset fixtures to the before-state snapshot (copy back from recipes-before/)
-cp /tmp/opencode/<plan>-e2e/recipes-before/*.recipe.json /tmp/opencode/<plan>-e2e/recipes/
-# 2. Clear the recipe/FTS caches so the stale in-memory/library state is gone
-rm -f <repo-root>/cache/recipe/*.sqlite
-rm -rf <repo-root>/cache/fts/*
-# 3. Restart the server (fresh process, fresh scan)
-python .agents/skills/lora-manager-e2e/scripts/start_server.py --port {PORT} --restart --wait --timeout 30 --detach
-# 4. Re-verify server listening + reload the browser page
-```
-
-## Server Lifecycle
-
-- **Detached launch is mandatory**: the standalone server dies with the shell unless launched via `setsid` (or the helper script's `--detach`). Use `setsid nohup python standalone.py --port {PORT} --host 127.0.0.1 ... < /dev/null &`.
-- **Verify with `ss -tlnp`** after every (re)start; do not proceed on a blind "server starting" message.
-- **Never kill pre-existing processes** — only kill the E2E server PID you started (`start_server.py --restart` kills only PIDs it manages via its pidfile). The live ComfyUI or a stale QA Chrome must never be killed as part of cleanup unless explicitly identified as such (see Chrome troubleshooting).
-- **Record your PID for cleanup**: note the PID printed/pidfile, and stop exactly that PID at the end (`kill <PID>`, then confirm with `ss -tlnp` that `{PORT}` is released).
-
-## Chrome DevTools MCP Troubleshooting
-
-### Stale profile lock ("browser is already running" / `list_pages` fails)
-
-A Chrome profile can be held by a stale Chrome from a prior MCP session, which makes `list_pages` fail with "browser is already running":
-
-1. Identify the stale Chrome — it owns the profile dir in `--user-data-dir` (e.g. `~/.config/chrome-dev-profile`). Find its process:
-   ```bash
-   ps -ef | grep -i '[c]hrome.*user-data-dir'
-   ```
-2. Confirm it is a QA Chrome from a completed task (its parent is an old MCP/browser process, it is NOT the live ComfyUI server, and it is NOT your current MCP instance).
-3. Kill ONLY that stale Chrome:
-   ```bash
-   kill <stale-chrome-pid>
-   ```
-   Never kill the live server or unrelated processes.
-4. Retry `list_pages`. The current MCP will spawn a fresh browser.
-
-### Screenshot-write restrictions
-
-The chrome-devtools MCP may refuse to write into paths outside its configured workspace roots (e.g. the worktree `.omo/evidence/...` canonicalizing to an unmapped path). Workaround:
-
-```bash
-# 1. Save the screenshot to /tmp via the MCP
-#    take_screenshot(filePath="/tmp/<plan>-e2e/recipe-b-after.png", format="png")
-# 2. Copy it into the evidence dir from the shell
-mkdir -p <repo-root>/.omo/evidence/screenshots
-cp /tmp/<plan>-e2e/recipe-b-after.png <repo-root>/.omo/evidence/screenshots/
-```
-
-## 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.
-
-## Available Scripts
-
-### scripts/start_server.py
-
-Starts or restarts the LoRa Manager standalone server for E2E testing.
-
-```bash
-python scripts/start_server.py [--port PORT] [--restart] [--wait] [--timeout SECONDS] [--detach]
-```
-
-Options:
-- `--port`: Server port (default: 8188). The script exits early with a clear message if the port is already in use by an unrelated process.
-- `--restart`: Kill the E2E server this script previously managed (tracked via `/tmp/lora-manager-e2e-server-{PORT}.pid`) before starting. If unrelated processes still hold the port after that, the script reports them and aborts instead of killing them.
-- `--wait`: Wait for the server to be ready before exiting.
-- `--timeout`: Readiness wait timeout in seconds (default: 30).
-- `--detach`: Launch the server fully detached (`setsid`-style, survives shell death — REQUIRED for E2E). Default off: a normal background process that dies with the shell.
-
-### scripts/wait_for_server.py
-
-Polls the server until ready or timeout.
-
-```bash
-python scripts/wait_for_server.py [--port PORT] [--timeout SECONDS]
-```
-
-## 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()
-```
-
-## Cleanup
-
-Always ensure proper cleanup after tests:
-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. Remove the sandbox: `rm -rf /tmp/opencode/<plan>-e2e` and `<repo-root>/settings.json` + `<repo-root>/cache` (both gitignored).
-4. Re-run the real-data protection check from the SANDBOX section and record the result in your evidence.

-## Common LoRa Manager Test Patterns
-
-### Verify LoRA Cards Loaded
-
-```python
-navigate_page(type="url", url="http://127.0.0.1:{PORT}/loras")
-wait_for(text="LoRAs", timeout=10000)
-
-# Check if cards loaded
-result = evaluate_script(function="""
-() => {
-    const cards = document.querySelectorAll('.lora-card');
-    return {
-        count: cards.length,
-        hasData: cards.length > 0
-    };
-}
-""")
-```
-
-### Search and Verify Results
-
-```python
-fill(uid="search-input", value="character")
-press_key(key="Enter")
-wait_for(timeout=2000)  # Wait for debounce
-
-# Check results
-result = evaluate_script(function="""
-() => {
-    const cards = document.querySelectorAll('.lora-card');
-    const names = Array.from(cards).map(c => c.dataset.name || c.textContent);
-    return { count: cards.length, names };
-}
-""")
-```
-
-### Check API Response
-
-```python
-# Trigger API call
-evaluate_script(function="""
-() => window.loraApiCallPromise = fetch('/loras/api/list').then(r => r.json())
-""")
-
-# Wait and get result
-import time
-time.sleep(1)
-
-result = evaluate_script(function="""
-async () => await window.loraApiCallPromise
-""")
-```
-
-### Monitor Console for Errors
-
-```python
-# Before test: clear console (navigate reloads)
-navigate_page(type="reload")
-
-# ... perform actions ...
-
-# Check for errors
-errors = list_console_messages(types=["error"])
-assert len(errors) == 0, f"Console errors: {errors}"
-```
-
-## 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.

-> **Run preconditions (from SKILL.md)**: every run uses the **sandboxed** standalone
-> server on a free port `{PORT}` (default candidate `8188`, only if actually free — pick
-> e.g. `8199` when `8188` is occupied by a live ComfyUI). Fixtures live in the sandboxed
-> `recipes_path` as `f"{id}.recipe.json"` files with matching in-JSON `id`; the real user
-> config and real library are never touched (record protection proof before/after).

+
+Locale files are in `locales/` (en, zh-CN, zh-TW, ja, ko, fr, de, es, ru, he).
+
+After adding keys to `en.json` and syncing, **stop**: the `[TODO: Translate]` placeholders in
+the other locales are the expected end state during feature development. Do NOT translate
+proactively — translate only when the feature owner explicitly asks (see
+`docs/i18n-translation-guidelines.md` §7).
+
+**Before translating anything, read `docs/i18n-translation-guidelines.md`** — it defines the
+term conventions (e.g. "Recipe" stays untranslated in French, 配方 in Chinese; model-type and
+brand names are never translated), per-locale preferred renderings, placeholder rules, and
+the known confusion hot-spots.
+
+## 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`
+#### Imports & Modules
-- 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

-## JavaScript/TypeScript Code Style
-
-### 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

 - 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
+- API endpoints follow `/loras/*`, `/checkpoints/*`, `/embeddings/*`, `/other/*` patterns
-- `ModelScanner` for file discovery, hash deduplication
+- Route registrars organize endpoints by domain: `ModelRouteRegistrar`, `RecipeRouteRegistrar`, etc.
-- `PersistentModelCache` (SQLite) for persistence
+- Request handlers in `py/routes/handlers/` implement route logic
-- Route registrars: `ModelRouteRegistrar`, endpoints: `/loras/*`, `/checkpoints/*`, `/embeddings/*`
+- All routes use aiohttp, return `web.json_response` or `web.Response`
-- WebSocket via `WebSocketManager` for real-time updates
+- Endpoints consumed by the companion browser extension (lm-civitai-extension)
+  MUST also accept `GET` with query-string params: the extension is GET-only by
+  convention (see its AGENTS.md), even for state-changing operations such as
+  `GET /api/lm/recipe/{recipe_id}/reimport`
 
 ### Recipe System
 
-- Base: `py/recipes/base.py`, Enrichment: `RecipeEnrichmentService`
+- Base: `py/recipes/base.py`, Enrichment: `RecipeEnrichmentService` in `py/recipes/enrichment.py`
-- Parsers: `py/recipes/parsers/`
+- 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
+- `settings.json.example` is intentionally minimal (see Important Notes); all
+  other defaults live in `DEFAULT_SETTINGS` (`py/services/settings_manager.py`)
+
+### 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`
+
+### UI Verification (manual default)
+
+UI/layout changes are verified by the user by eye — do NOT spin up a sandbox,
+standalone server, or browser automation to "prove" a visual fix. Ask the user to
+look instead. The full browser E2E ceremony (server + Chrome DevTools MCP +
+screenshots) is slow, token-heavy, and fragile; reserve it for genuine
+server+browser integration bugs, and only when the user explicitly agrees.
+
+If a cross-layer issue ever needs a live server, the sandboxed helpers live in
+`scripts/e2e/` (`start_server.py`, `wait_for_server.py`). Non-negotiable rules:
+
+- Always launch with `--settings-path <sandbox>/settings` and sandboxed
+  `folder_paths` under `/tmp` — the repo folder is the real plugin folder and a
+  `settings.json` there is read by the live instance. Never touch real config or
+  real model libraries.
+- Never kill a process you did not start; `start_server.py` tracks its own PIDs
+  via pidfile and refuses to touch unrelated processes on the port.
+- Abort after ~30 minutes or 3 consecutive tool failures; report `BLOCKED` with
+  observed state instead of retrying blindly. Clean up sandbox and server after.
+
+## 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)
+- **`settings.json.example` must stay minimal**: only `use_portable_settings`,
-- Detection: `os.environ.get("LORA_MANAGER_STANDALONE", "0") == "1"`
+  `civitai_api_key`, and the four core `folder_paths` keys (`loras`,
+  `checkpoints`, `unet`, `embeddings`). Do NOT add optional/default keys
+  (model-category folders, `default_*_root`, `auto_organize_exclusions`, etc.)
+  to this file unless the user explicitly asks for it. Defaults belong in
+  `DEFAULT_SETTINGS` in `py/services/settings_manager.py`.

+# 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, 1982 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.
+>
+> **Status (2026-09, Other Models):** the `other` model type (VAE / Upscaler / Text Encoder /
+> CLIP Vision / ControlNet) and the Other Models opt-in toggles added 36 new keys; all of them
+> are now translated in all 9 locales (terminology in §2 "Other Models feature"). There are no
+> remaining `[TODO: Translate]` placeholders in any locale.
+>
+> **Status (2026-09, revision):** `other.disabled.description`, `banners.otherModels.content` and
+> `settings.folderSettings.enableOtherModelsHelp` were refreshed in `en.json` to name all five
+> sub_types (they had listed four, which read as "these are what enabling manages") and
+> re-translated in all 9 locales in the same pass. `clip_vision` and `controlnet` are now both
+> opt-in, so the first two describe **capability** and the third the **master switch**, not the
+> default set — keep all three enumerating the full five (`VAE / upscaler / text encoder /
+> CLIP vision / ControlNet` in `en`; locale slash-list casing follows each file's existing
+> `VAE / Upscaler / Text Encoder / …` style, de compounds as `CLIP-Vision- und ControlNet-Ordner`).
+>
+> **Status (2026-09, "no folders found" state):** the Other Models page gained an *enabled but
+> nothing to scan* empty state with 6 new keys (`other.noPaths.*`); translated in all 9 locales
+> in the same pass. The `folder_paths` JSON snippet shown in that state lives in
+> `templates/other.html`, **not** in the locale files, so it is never translated — only the
+> surrounding prose is. Terminology added in §2.
+
+---
+
+## 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
+  `[TODO: Translate]` placeholder copies) — **then stop**. Do NOT translate proactively:
+  placeholders are the expected end state during feature development, and translations are
+  filled in only when the feature owner explicitly asks (workflow details in §7).
+- 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 | — |

+| bulk | groupé(e) | unify with "par lot / mode lot" variants |
+
+### de
+
+| Term | Use | Fix |
+|---|---|---|
+| recipe | Rezept/Rezepte | leftover English "Recipe" keys → Rezept (e.g. `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 |
+|---|---|---|
+| recipe | receta(s) | — |
+| Checkpoint | Checkpoint | 5 statistics keys "Punto(s) de control" → "Checkpoints" (`statistics.metrics.checkpoints`, `statistics.insights.unusedCheckpoints.*`, `statistics.modelTypes.checkpoint`) |
+| trigger words | palabra(s) de activación | 2 keys already use it; ~15 keys "palabra(s) clave" (reads as search keyword) → unify |
+| base model | modelo base | — |
+| preset | preajuste | 3 keys keep English "preset", 1 "preestablecido" → preajuste |
+| workflow | pick flujo de trabajo or workflow | currently 21× "flujo de trabajo" vs 10× "workflow" |
+| bulk | masivo / por lotes | unify; "Batch Import" → traducción |
+| tags | etiquetas | — |
+
+### ru
+
+| Term | Use | Fix |
+|---|---|---|
+| recipe | рецепт(ы) | English leftovers: `initialization.recipes.title`, `recipes.batchImport.*`, `toast.recipes.recipeSaved` → translate |
+| Checkpoint | Checkpoint (recommended) | 3 variants today: "Checkpoint" (17 keys), «Чекпойнт», «Контрольная точка» (statistics, 6 keys) — statistics MUST drop «Контрольная точка» |
+| Embedding | Embedding | «Эмбеддинг» variant exists in `settings.priorityTags.modelTypes.embedding` — unify |
+| prompt | промпт | 8 keys use «запрос» (reads as "database/HTTP request") → «промпт» |
+| base model | базовая модель | — |
+| preset | пресет | `header.theme.presets` "Предустановки" → пресеты |
+| workflow | Workflow (recommended) | «рабочий процесс» used in 4 keys — unify |
+| hash | pick хеш or хэш | both spellings co-occur |
+| tag(s) | тег(и) | — |
+| typos | — | `settings.misc.loraSyntaxFormatHelp`: «безпотерьного» → «беспотерьного» |
+
+### he
+
+| Term | Use | Fix |
+|---|---|---|

+| Embedding | Embedding | `statistics` keys use הטמעות → Embedding |
+| prompt | pick הנחיה or פרומפט | 9 keys הנחיה vs 3 פרומפט — unify (recommend פרומפט, SD-community loanword) |
+| preset | קביעה מראש | `header.filter.presetOverwriteConfirm` uses פריסט → unify |
+| hash | pick one of האש / גיבוב / hash | 3 variants co-occur — unify (recommend hash or גיבוב) |
+| metadata | pick מטא-דאטה or מטא-נתונים | 38 vs 17 keys — unify |
+| model | מודל | 13 keys use דגם/דגמים — unify |
+| bulk | pick one of 5 variants | 5 different renderings ("כמות גדולה", "המוני", "קבוצתי", "אצווה", …) — unify; `loras.controls.bulk.action` "כמות גדולה" reads as "large quantity" |
+
+### ja
+
+| Term | Use | Fix |
+|---|---|---|
+| recipe | レシピ | `initialization.recipes.title` keeps English "Recipe Manager" — translate to レシピマネージャー |
+| Checkpoint | Checkpoint or チェックポイント (pick one) | 3 variants: Checkpoint (~14), checkpoint lowercase (4), チェックポイント (4, e.g. `settings.priorityTags.modelTypes.checkpoint`) |
+| Embedding | Embedding | 4 keys lowercase "embedding" mid-sentence |
+| bulk | 一括 | `modals.checkUpdates.tip` "バルクモード" → 一括モード |

+| Embedding | Embedding | 3 keys 임베딩 (`settings.priorityTags.modelTypes.embedding`, `uiHelpers.nodeSelector.embedding`) |
+| base model | 베이스 모델 | 6 keys «기본 모델» read as "default model" → 베이스 모델 (`settings.downloadSkipBaseModels.*`, `toast.loras.downloadSkippedByBaseModel`) |

+
+### Other Models feature (VAE / Upscaler / Text Encoder / CLIP Vision / ControlNet)
+
+The `other` model type exposes five sub_types. They are **model-type names**, so they follow
+R3 and stay in Latin in every locale. The `settings.folderSettings.subType*` values are
+therefore **intentionally byte-identical to `en.json`** (same precedent as
+`settings.priorityTags.modelTypes` / `checkpoints.modelTypes.checkpoint`) — a §6 sweep must
+not "fix" them.
+
+| Term | Rendering | Note |
+|---|---|---|
+| VAE | `VAE` everywhere | acronym, always upper-case |
+| Upscaler | `Upscaler` everywhere | CivitAI `ModelType` name |
+| Text Encoder | `Text Encoder` everywhere | de compounds as `Text-Encoder-Stammordner` |
+| CLIP Vision | `CLIP Vision` everywhere | de compounds as `CLIP-Vision-Stammordner` |
+| ControlNet | `ControlNet` everywhere | brand casing, capital N |
+
+In prose these names sit next to localized nouns the same way `Diffusion Model` does
+(zh `VAE 根目录`, ja `VAEルート`, ko `VAE 루트`, ru `Корневая папка VAE`).
+
+**"Other Models" is the page/feature name, not a model type — translate it:**
+
+| Locale | `other.title` | `header.navigation.other` |
+|---|---|---|
+| fr | Autres modèles | Autres |
+| zh-CN | 其他模型 | 其他 |
+| zh-TW | 其他模型 | 其他 |
+| ja | その他のモデル | その他 |
+| ko | 기타 모델 | 기타 |
+| de | Weitere Modelle | Andere |
+| es | Otros modelos | Otros |
+| ru | Другие модели | Другое |
+| he | מודלים אחרים | אחרים |
+
+`settings.folderSettings.otherSubTypes` ("Managed Types") must name **model** types, matching
+each locale's `header.filter.modelTypes` rendering (zh `管理的模型类型`, ja `管理するモデルタイプ`,
+de `Verwaltete Modelltypen`, …).
+
+The "no folders found" empty state (`other.noPaths.*`) uses two phrases that must stay
+consistent whenever that copy is edited. `folder key` means the `folder_paths` key name
+(`vae`, `upscale_models`, … — Latin per the table above); `on disk` means the folder must
+physically exist:
+
+| Phrase | Rendering |
+|---|---|
+| folder key | zh-CN 文件夹键 · zh-TW 資料夾鍵 · ja フォルダーキー · ko 폴더 키 · fr clé de dossier · de Ordnerschlüssel · es clave de carpeta · ru ключ папки · he מפתח תיקייה |
+| on disk | zh-CN 在磁盘上 · zh-TW 在磁碟上 · ja ディスク上 · ko 디스크에 · fr sur le disque · de auf dem Datenträger · es en el disco · ru на диске · he בדיסק |
+
+`settings.json` and `ComfyUI` stay verbatim in every locale; "reload this page" / "restart
+LoRA Manager" reuse each locale's existing restart wording (`settings.extraFolderPaths.*`).
+
+---
+
+## 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.
+
+| Term | fr | de | es | ru | he | ja | ko | zh-CN | zh-TW |
+|---|---|---|---|---|---|---|---|---|---|
+| recipe | Recipe | Rezept | receta | рецепт | מתכון | レシピ | 레시피 | 配方 | 配方 |
+| Checkpoint | Checkpoint | Checkpoint | Checkpoint | Checkpoint | Checkpoint | Checkpoint | Checkpoint | Checkpoint | Checkpoint |
+| Embedding | Embedding | Embedding | Embedding | Embedding | Embedding | Embedding | Embedding | Embedding | Embedding |
+| prompt | Prompt | Prompt | prompt | промпт | פרומפט | プロンプト | 프롬프트 | 提示词 | 提示詞 |
+| base model | modèle de base | Basismodell | modelo base | базовая модель | מודל בסיס | ベースモデル | 베이스 모델 | 基础模型 | 基礎模型 |
+| preset | préréglage | Voreinstellung | preajuste | пресет | קביעה מראש | プリセット | 프리셋 | 预设 | 預設 |
+| workflow | Workflow | Workflow | workflow | Workflow | workflow | ワークフロー | 워크플로 | 工作流 | 工作流 |
+| hash | hash | Hash | hash | хеш | hash | ハッシュ | 해시 | 哈希 | 雜湊 |
+| metadata | métadonnées | Metadaten | metadatos | метаданные | מטא-נתונים | メタデータ | 메타데이터 | 元数据 | 中繼資料 |
+| tags | Tags | Tags | etiquetas | теги | תגיות | タグ | 태그 | 标签 | 標籤 |
+| duplicates | en double | Duplikate | duplicados | дубликаты | כפילויות | 重複 | 중복 | 重复项 | 重複項 |
+| bulk | groupé | Massen- | por lotes | пакетный | בכמות גדולה | 一括 | 일괄 | 批量 | 批量 |
+
+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`), model-type names (`settings.priorityTags.modelTypes.*`,
+`settings.folderSettings.subTypeVae` … `subTypeControlnet` — see §2), 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.
+
+### Anti-patterns checklist
+- [ ] Placeholders `{x}` / `{{x}}` differ from `en.json`
+- [ ] Same source term translated 2+ ways in the same file (see §5)
+- [ ] "Checkpoint" became a literal checkpoint; "recipe" became menu/prescription/food-cookbook
+- [ ] Brand names translated or transliterated (LoRA, CivitAI, ComfyUI, …)
+- [ ] Latin locale using full-width `：（）`; fr using `"` as apostrophe
+- [ ] Mixed 你/您, du/Sie, tú/usted
+- [ ] Full English sentences left behind (see §6)
+- [ ] Register/typos/mojibake; source string is stale vs `en.json` (compare semantics, not
+  just words)

+# 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 |
+| 2 | ~250–350 LOC | ~250–350 LOC (multi-file loop refactor + ModelVersionsTab + batch badge) | ~250–350 LOC (dialog tests greenfield) | Medium |

+**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.

+# Plan: "Other Models" Page — Unified Management for VAE / Upscaler / Text Encoder / etc.
+
+**Status:** v2 — **Phase 1 implemented** (2026-09-12, commits `27da7b3c` backend + `fa7ce725` frontend; verified live against a running ComfyUI instance: scan/hash/sub_type-derivation/fetch/previews all green). **Phase 2 implemented** (2026-09-12, per §9 design; full pytest + vitest green). **Phase 3 implemented** (§11: opt-in management toggles; default off). **i18n done** (2026-09-13): all 36 new keys translated in the 9 non-English locales — the `[TODO: Translate]` placeholders left by the sync script during development are gone (see `docs/i18n-translation-guidelines.md` §2, "Other Models feature"). **Default set revised (pre-release):** only `vae` / `upscaler` / `text_encoder` are managed by default — `clip_vision` and `controlnet` are both opt-in (§2, §11.1.1).
+**Scope (Phase 1):** scan + manage (list, search, filter, tags, folders, preview, rename, move, delete/exclude, CivitAI metadata fetch) for a new model type `other`, exposed as a new web page. **Phase 2 (§9):** one-click download from CivitAI for these types.
+
+## 1. Goal
+
+Today the manager supports three model types:
+
+| page | model_type | sub_types |
+|---|---|---|
+| `/loras` | `lora` | `lora`, `locon`, `dora` |
+| `/checkpoints` | `checkpoint` | `checkpoint`, `diffusion_model` |
+| `/embeddings` | `embedding` | `embedding` |
+
+Add a fourth page that manages "everything else" — VAE, upscalers, text encoders / CLIP, CLIP vision, optionally ControlNet — with a folder→sub_type mapping table so new ComfyUI folder categories can be added later by configuration, not code.
+
+## 2. Locked Decisions
+
+1. **Architecture: one scanner + one service + one page, sub_type derived by location.**
+   Replicates the checkpoint pattern (`CheckpointScanner` aggregates `checkpoints` + `unet` roots and derives `checkpoint` vs `diffusion_model` from the root containing the file, `py/services/checkpoint_scanner.py:384-415`). One `OtherScanner` aggregates all enabled folder roots; `resolve_sub_type_for_path()` maps each root to a sub_type. No per-category scanners.
+
+2. **Naming: internal `model_type = "other"`, route prefix `/other`, page id `other`.**
+   - `misc` is rejected: `py/routes/misc_routes.py` already owns that name for system/settings routes (`/api/lm/settings`, `/api/lm/doctor/*`).
+   - `components` is rejected: `templates/components/` and `static/js/components/` directories would make `components.html` / `components.js` confusing neighbors.
+   - `other` matches CivitAI's `Other` fallback type semantics. The **display name** is an i18n string (`other.title`, e.g. "Other Models") and can be renamed later without touching code.
+
+3. **sub_type values:** snake_case, aligned with CivitAI `ModelType` semantics:
+
+   | sub_type | ComfyUI `folder_paths` key(s) | CivitAI ModelType | enabled by default |
+   |---|---|---|---|
+   | `vae` | `vae` | `VAE` | yes |
+   | `upscaler` | `upscale_models` | `Upscaler` | yes |
+   | `text_encoder` | `text_encoders`, `clip` (legacy) | `TextEncoder` (CLIP is retired upstream) | yes |
+   | `clip_vision` | `clip_vision` | `CLIPVision` | no (mapping present, opt-in) |
+   | `controlnet` | `controlnet` | `Controlnet` | no (mapping present, opt-in) |
+
+   New folder categories = one line in the mapping table (see §4.1).
+
+   **Why only three are on by default** (revised in Phase 3, before release):
+   VAE, upscalers and text encoders are dependency-style assets every pipeline
+   needs, and "which one am I actually using" is the recurring problem they
+   solve. `clip_vision` and `controlnet` are workflow-driven instead
+   (IPAdapter/SVD image conditioning; per-workflow ControlNet variants), and
+   ControlNet libraries routinely run to dozens of files, so both are treated
+   symmetrically as opt-in. Enumerating all five as "the default set" was not
+   defensible on demand breadth alone.
+
+4. **Phase 1 = scan/manage only.** Downloads from CivitAI (`download_manager.py` type mapping, default-root settings keys, download routing) are Phase 2 (§9). CivitAI **metadata fetch** for existing files IS in Phase 1 (hash-based lookup is type-agnostic; only the type-validation hook needs new values).
+
+5. **Out of scope (default off, revisit later):** usage statistics buckets, recipe matching (`recipe_scanner.py` only merges lora+checkpoint scanners), statistics page, embeddings re-classification (stays its own page — merging would be a breaking change).
+
+## 3. Why This Works With Minimal Churn
+
+- `ModelScanner` (`py/services/model_scanner.py:93`) is specialized entirely via constructor params (`model_type`, `model_class`, `file_extensions`) + optional hooks (`adjust_metadata`, `adjust_cached_entry`, `resolve_sub_type_for_path`, `model_scanner.py:1429-1443`).
+- `BaseModelService` subclasses can be one method (`EmbeddingService` implements only `format_response`, `py/services/embedding_service.py:12`).
+- Routes: `ModelServiceFactory.register_model_type()` (`py/services/model_service_factory.py:120-136`) + `COMMON_ROUTE_DEFINITIONS` (`py/routes/model_route_registrar.py:23-149`) generate the full `/api/lm/{prefix}/*` surface (~50 endpoints) plus the `GET /{prefix}` page route.
+- `PersistentModelCache` (`py/services/persistent_model_cache.py:526-606`) is a single `models` table keyed `(model_type, file_path)` with `model_type` as free text — **zero schema change**.
+- Frontend `apiConfig.js` (`static/js/api/apiConfig.js:51`) generates all endpoints from the model-type string; `ModelCard.js:670-675` renders the sub_type badge from data; the checkpoints page already demonstrates the "one page, multiple sub_types" filter (`header.html:298`).
+
+## 4. Backend Changes
+
+### 4.1 New constants — `py/utils/constants.py`
+
+```python
+# folder_paths key -> sub_type; single source of truth for extensibility
+OTHER_MODEL_FOLDER_SUBTYPES = {
+    "vae": "vae",
+    "upscale_models": "upscaler",
+    "text_encoders": "text_encoder",
+    "clip": "text_encoder",        # legacy ComfyUI key
+    "clip_vision": "clip_vision",
+    "controlnet": "controlnet",
+}
+DEFAULT_OTHER_MODEL_FOLDERS = ("vae", "upscale_models", "text_encoders", "clip", "clip_vision")
+VALID_OTHER_SUB_TYPES = ["vae", "upscaler", "text_encoder", "clip_vision", "controlnet"]
+# CivitAI model.type values accepted for this page (fetch-metadata validation)
+VALID_OTHER_CIVITAI_TYPES = {"vae", "upscaler", "textencoder", "clipvision", "controlnet", "other"}
+```
+
+Also extend `CIVITAI_USER_MODEL_TYPES` (`constants.py:90`) if user-model queries should include these types.
+
+### 4.2 New files (mirror the embedding/checkpoint implementations)
+
+1. **`py/utils/models.py`** — add `OtherModelMetadata(BaseModelMetadata)`: default `sub_type="vae"` placeholder overridden by scanner hook; `from_civitai_info` mapping CivitAI types → our sub_types (`TextEncoder`→`text_encoder`, `CLIPVision`→`clip_vision`, `Upscaler`→`upscaler`, `VAE`→`vae`, `Controlnet`→`controlnet`, else `other`-ish fallback to folder-derived sub_type).
+2. **`py/services/other_scanner.py`** — `OtherScanner(ModelScanner)`:
+   - `model_type="other"`, extensions: reuse the checkpoint set (`safetensors/pt/pt2/bin/pth/pkl/sft/gguf`).
+   - `get_model_roots()`: iterate `OTHER_MODEL_FOLDER_SUBTYPES` ∩ enabled keys, pull each from `config` (§4.3); dedupe; build `root → sub_type` map (normalized abspaths; multiple keys may share a sub_type).
+   - Implement all three hooks like `CheckpointScanner` (`checkpoint_scanner.py:384-415`): `resolve_sub_type_for_path` by longest-prefix root match, `adjust_metadata`, `adjust_cached_entry` (sub_type is re-derived on cache load, never persisted).
+   - **Lazy hashing, checkpoint-style**: text encoders (T5-XXL ≈ 10 GB) make eager sha256 painful. Copy the `hash_status="pending"` + singleflight `calculate_hash_for_model` pattern from `CheckpointScanner`.
+3. **`py/services/other_model_service.py`** — `OtherModelService(BaseModelService)`, `format_response` only (no usage_count, like `EmbeddingService`).
+4. **`py/routes/other_routes.py`** — `OtherRoutes(BaseModelRoutes)`, `template_name="other.html"`, hooks:
+   - `_validate_civitai_model_type` → `VALID_OTHER_CIVITAI_TYPES`
+   - `_get_expected_model_types`, `_parse_specific_params` (no type-specific download params in Phase 1)
+   - `initialize_services()` on `app.on_startup` pulling `ServiceRegistry.get_other_scanner()`.
+
+### 4.3 `py/config.py`
+
+- New `other_roots` property: for each enabled key in `OTHER_MODEL_FOLDER_SUBTYPES`, `folder_paths.get_folder_paths(key)` (plugin mode) — standalone mode needs nothing new: `MockFolderPaths` (`standalone.py:66-105`) already serves arbitrary keys from `settings.json.folder_paths`.
+- Follow the existing per-type recipe: an `_prepare_other_paths()` (dedupe + symlink registration; also **cross-scanner overlap detection** — warn if an `other` root is already covered by checkpoints/unet/embedding roots, mirroring the checkpoint/unet overlap check).
+- Wire into: `_apply_library_paths`, `_symlink_roots()`, `_rebuild_preview_roots()` (hard requirement — preview images are served per registered root), `save_folder_paths_to_settings()`.
+
+### 4.4 Existing-file edits (the "type string scatter" — each is a small branch/entry)
+
+| file | change |
+|---|---|
+| `py/services/model_service_factory.py:120` | register `("other", OtherModelService, OtherRoutes)` in `register_default_model_types()` |
+| `py/services/service_registry.py` | add `get_other_scanner()` (mirror `:297` `get_embedding_scanner`) |
+| `py/services/model_scanner.py:67` | `PAGE_TYPE_MAP['other'] = 'other'` (WebSocket progress) |
+| `py/services/base_model_service.py:896-906` | `get_model_types()` branch → `VALID_OTHER_SUB_TYPES` |
+| `py/lora_manager.py` | `_initialize_services` scanner task list (`:219-242`), `_cleanup` cancel list (`:463`), `_cleanup_backup_files` roots (`:327-330`) |
+| `py/routes/handlers/misc_handlers.py` | `scanner_getters` (`:657-661`) + `scanner_factories` (`:757-759`) so Doctor / init-status / refresh-all see the new scanner |
+| `py/services/pending_delete_service.py` | `_PAGE_TYPE` map (`:57-61`) + scanner getter list (`:983-985`) |
+| `py/metadata_ops/__init__.py:36-38` | `SCANNER_TYPE_MAP['other']` |
+| `settings.json.example` | document optional `folder_paths` keys: `vae`, `upscale_models`, `text_encoders`, `clip_vision` |
+
+**Explicitly NOT touched in Phase 1:** `py/services/download_manager.py`, `py/services/download_routing.py`, `py/services/settings_manager.py` default-root keys, `py/routes/stats_routes.py`, `py/utils/usage_stats.py`, `py/services/recipe_scanner.py`, `py/metadata_collector/`, `py/nodes/`.
+
+**Zero-change confirmations (verified):** `PersistentModelCache`, `ModelUpdateService`, `DownloadedVersionHistoryService`, `MetadataSyncService` + provider chain (type-agnostic hash lookups), `ModelFileService` / `ModelMoveService` / `ModelLifecycleService` (scanner + model_type injected), `ModelCache` / `ModelHashIndex`, `AutoV3BackfillService`.
+
+## 5. Frontend Changes
+
+1. **`static/js/api/apiConfig.js`** — `MODEL_TYPES.OTHER = 'other'`; `MODEL_CONFIG.other` entry (displayName, singularName, `supportsMove`, `supportsBulkOperations`; no letter filter); endpoints come free from `getApiEndpoints()` (`:51`).
+2. **`static/js/api/otherApi.js`** — thin `OtherApiClient extends BaseModelApiClient` (mirror `embeddingApi.js`); register in `modelApiFactory.js`.
+3. **`static/js/other.js`** — page entry (mirror `embeddings.js`): `appCore.initialize()` + `createPageControls('other')` + `initializePageFeatures()` + `ModelDuplicatesManager` + `initActiveFiltersSync('other')`.
+4. **Controls & context menu** — `OtherControls extends PageControls` and `OtherContextMenu` (start from the embedding variants — the smallest); add branches in the two factories (`components/controls/index.js:15`, `components/ContextMenu/index.js:15`). Context-menu template block lives in `templates/other.html` (`{% block additional_components %}`, the checkpoints/embeddings pattern — do NOT touch the shared `context_menu.html`).
+5. **`templates/other.html`** — copy `embeddings.html`: same content blocks (controls + breadcrumb + duplicates banner + folder sidebar + `#modelGrid`), `data-page="other"`, main script `/loras_static/js/other.js`.
+6. **`templates/components/header.html`** — nav entry (`:23-43`, active when `request.path.startswith('/other')`); enable the `modelTypes` sub_type filter panel for `other` (`:298-305` pattern from checkpoints); check search-options panel conditions (`:199-224`).
+7. **`static/js/utils/constants.js`** — `MODEL_SUBTYPE_ABBREVIATIONS` (`:115`): `vae→VAE`, `upscaler→UPS`, `text_encoder→TE`, `clip_vision→CV`, `controlnet→CN`; matching `MODEL_SUBTYPE_DISPLAY_NAMES` (`:99`). (Unknown fallback already uppercases 4 chars, but explicit mappings read better.)
+8. **`static/js/core.js:110` `getPageType()`** — verify `data-page="other"` flows through `state.pages` generically; add only if the page list is enumerated anywhere.
+9. No change to `web/comfyui/top_menu_extension.js` (it opens `/loras`; page-to-page nav is the header bar).
+
+## 6. i18n
+
+- `locales/en.json`: add `other.title` (e.g. "Other Models") + minimal `other.contextMenu.*` / `other.modelTypes.*` keys; reuse `modelCard.*`, `loras.contextMenu.*`, `common.*` wherever possible (the established pattern — checkpoints/embeddings already reuse lora keys).
+- Run `python scripts/sync_translation_keys.py`; leave `[TODO: Translate]` placeholders in other locales (per `docs/i18n-translation-guidelines.md` §7 — do not translate proactively).
+
+## 7. Testing
+
+Follow existing conventions (`pytest.ini`, `tests/frontend/` vitest):
+
+1. **Backend (pytest, async where needed):**
+   - `OtherScanner` root aggregation + `resolve_sub_type_for_path` (file under `vae/` root → `vae`; `text_encoders` and legacy `clip` both → `text_encoder`; disabled `controlnet` root not scanned).
+   - Cache round-trip: sub_type re-derived via `adjust_cached_entry` (not persisted).
+   - Lazy hash: `hash_status="pending"` default; `calculate_hash_for_model` singleflight.
+   - `OtherRoutes` registration smoke test: `/api/lm/other/...` endpoints exist; `_validate_civitai_model_type` accepts `vae`/`upscaler`/`textencoder`, rejects `lora`.
+   - Config: `other_roots` in both modes (mock `folder_paths`, and standalone `settings.json.folder_paths`).
+2. **Frontend (vitest + jsdom, `tests/frontend/`):**
+   - `apiConfig`: `getApiEndpoints('other')` URL shapes; `modelApiFactory` returns the Other client.
+   - `ModelCard` badge rendering for new sub_types.
+   - `createPageControls('other')` / `createPageContextMenu('other')` factories.
+3. **Manual UI verification by the user** (per AGENTS.md — no sandbox/browser automation): page loads, scans a real library, sub_type filter + badges, context menu actions.
+
+## 8. Execution Order
+
+1. `constants.py` + `OtherModelMetadata` + `config.py` roots
+2. `OtherScanner` (+ registry, factory, `PAGE_TYPE_MAP`) → scanner unit tests green
+3. `OtherModelService` + `OtherRoutes` + handler/registrar wiring + `lora_manager.py` lifecycle → route tests green
+4. Doctor/pending-delete/metadata-ops scatter entries
+5. Template + header nav + frontend API/controls/context-menu/card badges → vitest green
+6. i18n keys + sync script
+7. `pytest` + `npm test` full runs; hand to user for manual UI check
+
+## 9. Phase 2 Detailed Design — CivitAI Downloads for `other`
+
+Designed 2026-09-12 against the Phase-1 code on this branch; decisions marked **[locked]** follow the same recommendations the feature owner approved for Phase 1.
+
+### 9.1 Download pipeline touch points
+
+Flow: `POST /api/lm/download-model` (`py/routes/model_route_registrar.py:104`; GET variant `:105` for the browser extension) → `ModelDownloadHandler.download_model` (`model_handlers.py:1740`) → `DownloadModelUseCase.execute` → `DownloadCoordinator.schedule_download` → `DownloadManager.download_from_civitai` (`download_manager.py:386`) → `_execute_original_download` (`:1415`). Inside, seven scatter points need an `other` branch:
+
+1. **Type map** (`:1496-1507`): accept `model.type.lower() in VALID_OTHER_CIVITAI_TYPES` → `model_type = "other"` (reuses the Phase-1 set, incl. `"other"` itself).
+2. **Early version-exists gate** (`:1436-1463`): add `other_scanner.check_model_version_exists`.
+3. **File-level exists gate** (`:1640-1655` → `_find_local_file_entry` `:320-346` → `_get_scanner_for_model_type` `:230-236`): add explicit `other` branch. **Trap**: the function currently falls through to the lora scanner for unknown types — `"other"` would silently dedupe against loras. Also narrow the fall-through to `"lora"` only / raise on unknown.
+4. **Version-level fallback gate** (`:1656-1688`): add `elif model_type == "other"`.
+5. **Default-root selection** (`:1690-1727`): for `other`, first resolve sub_type (§9.2), then read `default_other_roots[sub_type]` (§9.3); if sub_type is undecidable or no default root configured → error guiding the user to pick a folder explicitly.
+6. **Metadata class selection** (`:1909-1928`) + `_build_metadata_for_resume` (`:969-981`): add `OtherModelMetadata.from_civitai_info` branches.
+7. **Post-download cache write** (`_execute_download_pipeline` `:2622-2679`): add `other` scanner branch; `adjust_metadata` re-derives sub_type from the on-disk root automatically. `_get_supported_extensions_for_type` (`:2720-2744`): `other` reuses the checkpoint extension set.
+
+Hooks: `_record_downloaded_version_history` (model_type is free text — zero change); `_sync_downloaded_version` (`:1984` → scanner dispatch `:2130-2135`) add `other`; `py/utils/example_images_download_manager.py` scanner dispatch at `:411-421`, `:591-601`, `:1089+` — add `other` at all three (silent no-scanner otherwise).
+
+Path templates: `get_download_path_template("other")` is unset, so `other` resolves to a **flat** layout (empty template) — downloads land directly under the resolved sub_type root. This is deliberate: other-model roots are already split per sub_type (`default_other_roots`), and `priority_tags` has no `other` entry, so `{first_tag}` would fall back to an arbitrary CivitAI tag and scatter files into unstable folders. Users who want nesting can still set `download_path_templates["other"]` in `settings.json`. See `DEFAULT_DOWNLOAD_PATH_TEMPLATES` (`py/utils/constants.py`) and `DEFAULT_PATH_TEMPLATES` (`static/js/utils/constants.js`).
+
+### 9.2 File-level routing (model.type / file.type → sub_type) **[locked]**
+
+Table-driven, mirroring Phase 1. New in `py/utils/constants.py`:
+
+```python
+CIVITAI_FILE_TYPE_TO_OTHER_SUB_TYPE = {
+    "VAE": "vae", "Upscaler": "upscaler", "Text Encoder": "text_encoder",
+    "Vision Encoder": "clip_vision", "CLIPVision": "clip_vision",
+    "ControlNet": "controlnet",
+}
+```
+
+`download_routing.py` gains `resolve_other_download_sub_type(civitai_model_type, file_types, selected_file_type=None)` with fixed priority:
+
+1. **Explicit user file pick** (`file_params` from #1058's `_resolve_target_file`) — if the picked file's type maps, it wins even when model.type is `Checkpoint`.
+2. **model.type** via the existing `CIVITAI_TYPE_TO_OTHER_SUB_TYPE` (`constants.py:120-127`).
+3. **file.type fallback** — only when model.type maps to nothing (e.g. model.type `Other` or retired `CLIP`). MUST NOT override a mapped model.type: checkpoint models routinely bundle VAE/Text Encoder component files, and unconditional file-type routing would misroute them.
+4. Still undecidable → `None`; `use_default_paths` errors and the UI offers all other roots for manual selection.
+
+HTTP: extend `DownloadRoutingHandler.get_download_routing` (`download_routing_handlers.py:23`) with an `other` branch returning `{root_kind: "other", sub_type: ...}`; add `GET /api/lm/other/roots_by_subtype` in `OtherRoutes.setup_specific_routes` (data from `config._prepare_other_paths`'s per-key roots, aggregating `text_encoders` + legacy `clip` under `text_encoder`).
+
+### 9.3 Settings: single dict key `default_other_roots` **[locked]**
+
+Rejected: four flat keys (`default_vae_root`…) — each flat key costs ~13 touch points in `settings_manager.py` (defaults `:82-85`, `_check_and_auto_set` `:890-895`, `set()` `:1621-1628`, `_update_active_library_entry` `:738-805`, upsert/create signatures `:1953-2132`, `_build_library_payload` `:552-612`, `_sync_active_library_to_root` `:519-547`, three library constructors, frontend `DEFAULT_SETTINGS_BASE`), repeated per future sub_type.
+
+Chosen: one mapping key `default_other_roots: {sub_type: path}`, copying the `extra_folder_paths` precedent (generic Mapping handling at `:533-535`, `:573-578`, `:763-767`). `_check_and_auto_set` generalizes to per-sub_type candidates (union over that sub_type's folder keys — `text_encoder` → `text_encoders` + `clip`). `set()` validates keys against `VALID_OTHER_SUB_TYPES`.
+
+Also fix the Phase-1 omission: add `"other_scanner"` to `_notify_library_change` (`:2150-2156`) and `_notify_model_name_display_change` (`:1795-1800`) — otherwise switching libraries leaves the other page stale.
+
+### 9.4 Settings UI
+
+- `templates/components/modals/settings/library.html:34-40`: sub_type selectors after the existing four `setting_select`s (Jinja loop; controlnet selector only when `enabled_other_folders` includes it). Dict-subkey save helper `saveOtherRootSetting(subType, value)` alongside the flat `saveSelectSetting`.
+- `static/js/managers/SettingsManager.js:1547-1697`: `loadOtherRoots()` mirroring `loadUnetRoots()`, fed by `/api/lm/other/roots_by_subtype`; current values from `state.global.settings.default_other_roots`. `state/index.js:24` `DEFAULT_SETTINGS_BASE` += `default_other_roots: {}`.
+- Optional: one `other` row in the download-path-template block (`library.html:153-211`).
+- i18n: `settings.folderSettings.*` keys into `locales/en.json` + sync script; other locales keep `[TODO: Translate]`.
+- Settings GET (`misc_handlers.py:1528-1536`) already returns all non-sensitive keys — new key reaches the frontend for free.
+
+### 9.5 Frontend download entry
+
+- `templates/components/controls.html:83`: drop the `page_id != 'other'` exclusion on the download button (keyboard shortcut D self-enables via `PageControls.js:196-198`).
+- `OtherControls.js:22-55`: add `showDownloadModal: () => downloadManager.showDownloadModal()` (mirror `EmbeddingsControls.js:43-45`).
+- `DownloadManager.js` `proceedToLocationContent` (`:955-1017`): add `_resolveOtherSubType()` (mirror `_resolveIsDiffusionModel` `:1026`): selected file type → `/api/lm/download/routing` → `otherApiClient.fetchModelRoots(subType)` (new); default-root preselect reads `default_other_roots[subType]` instead of `` `default_${singularType}_root` `` (`:974`). Undecidable → list all other roots (`/api/lm/other/roots`) for manual pick; an explicit save_dir skips backend default-root logic, so the two paths cannot disagree.
+- `ModelVersionsTab` download buttons are modelType-generic and already work via `getModelApiClient('other')`; context menu has no CivitAI download entry — no change.
+- Version-list type validation (`get_civitai_versions` → `_validate_civitai_model_type`) already accepts `VALID_OTHER_CIVITAI_TYPES` from Phase 1.
+
+### 9.6 CivitAI type mapping decisions **[locked]**
+
+- Download accepts exactly `VALID_OTHER_CIVITAI_TYPES` (`VAE, Upscaler, TextEncoder, CLIP, CLIPVision, Controlnet, Other`) — reuse the Phase-1 tables; do NOT create new ones.
+- Extend `CIVITAI_USER_MODEL_TYPES` (`constants.py:133-137`) with the 7 aliases, and point them at the other scanner / `"other"` history bucket in `misc_handlers.py` (`type_scanner_map` `:2793-2797`, `downloaded_version_map` `:2821-2827`) — otherwise creator pages silently filter these models while downloads claim support.
+- Fix (small Phase-1 bug): `OtherModelMetadata.from_civitai_info` (`py/utils/models.py:343`) reads `version_info.get("type")`, but the type lives at `version["model"]["type"]` — the mapping never fires and always degrades to the placeholder. Read `version_info.get("model", {}).get("type")` instead. (`CheckpointMetadata:290` has the same shape; leave it alone here.)
+
+### 9.7 Tests
+
+Existing base: `tests/services/test_download_manager_basic.py` (incl. `test_download_rejects_unsupported_model_type` `:1336`), `test_download_manager_error.py`, `test_download_manager_concurrent.py`, `tests/integration/test_download_flow.py`, `tests/services/test_settings_manager.py`; frontend `tests/frontend/managers/downloadManager.routing.test.js`, `settingsManager.library.test.js`.
+
+Add: (1) `resolve_other_download_sub_type` unit tests — every priority tier, bundled-component anti-misrouting, undecidable → None, civarchive-shaped payload; (2) download_manager — six model.types accepted → other scanner (mock), unknown still rejected, no lora-scanner fall-through, per-sub_type default roots + unconfigured error, resume metadata, extension set; (3) settings_manager — `default_other_roots` defaults/auto-set (incl. text_encoder dual-key union)/library sync/upsert passthrough/illegal sub_type rejection; (4) routes — `/api/lm/download/routing` other branch, `roots_by_subtype` shape; (5) example-images dispatch accepts `other` (3 sites); (6) vitest — `_resolveOtherSubType` + root select + default preselect, `loadOtherRoots`; (7) user-models existsLocally for VAE.
+
+### 9.8 Phase 2 file list
+
+Backend: `py/utils/constants.py`, `py/services/download_routing.py`, `py/routes/handlers/download_routing_handlers.py`, `py/services/download_manager.py`, `py/utils/example_images_download_manager.py`, `py/services/settings_manager.py`, `py/utils/models.py`, `py/routes/other_routes.py`, `py/routes/handlers/misc_handlers.py`, `settings.json.example`.
+Frontend/templates: `templates/components/controls.html`, `static/js/components/controls/OtherControls.js`, `static/js/managers/DownloadManager.js`, `static/js/api/otherApi.js`, `templates/components/modals/settings/library.html`, `static/js/managers/SettingsManager.js`, `static/js/state/index.js`, `locales/en.json` + sync.
+
+## 10. Risks / Open Questions
+
+- **Root overlap**: a user may point `text_encoders` at a directory already scanned as checkpoints/unet. Realpath dedup inside one scanner won't catch cross-scanner overlap → the `_prepare_other_paths` overlap warning (§4.3) is the mitigation; duplicate cards across pages are cosmetic, not corrupting (cache keyed by `(model_type, file_path)`).
+- **Huge text encoders + lazy hash**: CivitAI fetch for a pending-hash model must trigger on-demand hash like checkpoints do — verify that flow (`calculate_hash_for_model`) is reachable from the `other` routes' fetch-metadata handler.
+- **Retired CivitAI types**: `CLIP`/`CLIPVision` are retired upstream (grandfathered for existing models); metadata fetch must tolerate both retired and current types — `VALID_OTHER_CIVITAI_TYPES` includes them deliberately.
+- **Standalone users** must add the new `folder_paths` keys to `settings.json` themselves; document in `settings.json.example` and the feature doc.
+- **Page display name** is i18n-only; if "Other Models" tests poorly, rename `other.title` without code changes.
+
+### Phase 2 risks
+
+- **Bundled component files**: checkpoint models routinely ship VAE/Text Encoder component files — file.type routing must stay a fallback (or explicit user pick), never an override (§9.2 priority is load-bearing; test it).
+- **`_get_scanner_for_model_type` lora fall-through** (`download_manager.py:236`): without an explicit `other` branch, dedupe checks run against the lora scanner — the most insidious trap in Phase 2.
+- **text_encoder dual folder keys** (`text_encoders` + legacy `clip`): default-root candidates, `roots_by_subtype`, and auto-set must all merge both keys; miss one and the default-root dropdown comes up empty.
+- **Undecidable sub_type** (model.type `Other` + unknown file types): must error and ask, never silently default to the vae folder.
+- **Lazy hash after download**: downloads carry CivitAI SHA256 (no recompute needed) — ensure the post-download cache write doesn't leave `hash_status="pending"`, or the next metadata fetch re-hashes a 10 GB file.
+- **CivArchive source**: same `_execute_original_download` path, same payload shape — cover it once in tests.
+
+## 11. Phase 3 — Opt-in Management Toggles (implemented)
+
+Designed 2026-09-13 against the Phase-1/2 code. Other Models is **opt-in**: after
+Phase 3 the feature ships disabled, so no other-model folder is scanned and the
+page shows an "enable" empty state until the user turns it on.
+
+### 11.1 Settings (global, not per-library)
+
+| key | type | default | meaning |
+|---|---|---|---|
+| `enable_other_models` | bool | `false` | master switch |
+| `enabled_other_sub_types` | list[str] | `["vae","upscaler","text_encoder"]` | allow-list; `clip_vision` and `controlnet` are opt-in (see §2) |
+
+`enabled_other_folders` (the unreleased, additive, no-UI backend key) was removed
+and replaced by the sub_type-level allow-list; there is no migration because the
+feature never shipped. `text_encoder` expands to `text_encoders` + legacy `clip`
+via `OTHER_SUB_TYPE_FOLDER_KEYS`.
+
+The default allow-list lives on five surfaces that must stay in sync:
+`DEFAULT_ENABLED_OTHER_SUB_TYPES` (`py/utils/constants.py`), `DEFAULT_SETTINGS`
+(`py/services/settings_manager.py`), the two `DEFAULT_SETTINGS_BASE` /
+`createDefaultSettings` lists (`static/js/state/index.js`), the
+`updateOtherModelsControls()` fallback (`static/js/managers/SettingsManager.js`)
+and the server-rendered Jinja fallback
+(`templates/components/modals/settings/library.html`).
+
+### 11.1.1 Legacy key handling in `Config._init_other_paths`
+
+ComfyUI's `folder_paths` rewrites legacy names before every access (`clip` →
+`text_encoders`, `unet` → `diffusion_models`) and registers both legacy
+directories under the canonical key, so `get_folder_paths("clip")` returns
+exactly the same list as `get_folder_paths("text_encoders")`. Querying both keys
+made the overlap guard fire twice with `please fix your path configuration` for a
+configuration the user cannot fix. `Config._collapse_legacy_folder_keys()` now
+drops a key when the host exposes `map_legacy` and resolves it to another queried
+key, and `_prepare_other_paths()` downgrades a same-`sub_type` duplicate to
+`debug` (a cross-`sub_type` collision still warns). In standalone mode
+`MockFolderPaths` has no `map_legacy` and its keys are independent
+`settings.json` entries, so every key is still queried there.
+
+`settings.json.example` intentionally stays minimal (only `use_portable_settings`,
+`civitai_api_key`, and the four core `folder_paths` keys: `loras`, `checkpoints`,
+`unet`, `embeddings`). Optional keys — including the other-model folder paths and
+`enable_other_models` — are NOT documented there; they live in `DEFAULT_SETTINGS`
+and reach the user's `settings.json` on demand. This supersedes the Phase-1/Phase-2
+notes that proposed adding the other-model folder keys to the example.
+
+### 11.2 Behaviour matrix
+

+
+### 11.3 Backend touch points
+
+- `py/utils/constants.py` — `DEFAULT_ENABLED_OTHER_SUB_TYPES`, `OTHER_SUB_TYPE_FOLDER_KEYS`, `normalize_other_sub_types`.
+- `py/config.py` — `_get_enabled_other_folder_keys()` is the single scan gate (master switch + allow-list); new `refresh_other_roots()` rebuilds roots + preview roots on toggle.
+- `py/services/settings_manager.py` — new defaults, `set()` normalization, `is_other_models_enabled()` / `get_enabled_other_sub_types()` / `is_other_sub_type_enabled()`, and `_apply_other_model_settings_change()` which reapplies config and calls `other_scanner.on_library_changed(reconcile=True)`.
+- `py/services/model_scanner.py` — `_should_keep_cached_entry()` hydration hook (default keep) plus `on_library_changed(reconcile=...)` / `initialize_in_background(reconcile=...)`; the hook filters `raw_data` and the hash/autov3 index rows.
+- `py/services/other_scanner.py` — drops persisted entries whose folder is no longer a managed root (sub_type is location-derived, so config is the source of truth).
+- `py/routes/other_routes.py` — `_validate_civitai_model_type` rejects everything while off / mapped-but-disabled sub_types; `_get_page_context_provider()` injects `other_disabled` into the template.
+- `py/routes/handlers/model_handlers.py` + `base_model_routes.py` — optional `page_context_provider` hook on `ModelPageView`.
+- `py/routes/handlers/download_routing_handlers.py` — returns `{sub_type: None, disabled: true, reason}` instead of guessing.
+- `py/services/download_manager.py` — rejects other-type downloads while off; disabled sub_type refuses default-path routing with a "pick a folder" error.
+- `py/routes/handlers/misc_handlers.py` — Doctor / init-status / refresh-all skip the other scanner while off (`_active_scanner_factories` / `_active_scanner_getters`).
+- `py/services/pending_delete_service.py` — deliberately untouched: the scanner stays registered so staged deletes still merge.
+
+### 11.4 Frontend
+
+Discoverability: the nav entry is hidden while the feature is off, and three
+lightweight surfaces replace it — a one-time announcement banner, the download
+toast, and the settings toggle itself.
+
+- `templates/components/header.html` + `static/css/components/header.css` — `nav-item--hidden` class (server-rendered when off, client-toggled after enabling) and the `fa-shapes` icon.
+- `templates/other.html` — `other_disabled` branch in `content` + `main_script`; page-scoped CSS for the empty state.
+- `static/js/other_disabled.js` — boots `appCore` (shared header) and delegates to the shared enable helper.
+- `static/js/utils/otherModels.js` — shared `enableOtherModels()` (POST settings + reload) and `openOtherModelsSettings()` (settings modal on the Library section); used by the disabled page, the banner and the download modal.
+- `static/js/managers/BannerService.js` — `other-models-announcement` banner (only when off and not dismissed; `priority: 0`, dismissal persisted via `dismissed_banners`) with Enable / Open Settings actions; `removeOtherModelsAnnouncement()` drops it without persisting a dismissal.
+- `templates/components/modals/settings/library.html` + `SettingsManager.updateOtherModelsControls()` / `saveEnabledOtherSubTypes()` / `updateOtherModelsNavVisibility()` — master toggle + five sub_type checkboxes; unchecked/disabled sub_types have their default-root select disabled.
+- `static/js/managers/DownloadManager.js` — a disabled routing answer surfaces a `showActionToast` with an "Enable Other Models" action (opening settings) and falls back to manual selection.
+- i18n: `settings.folderSettings.*`, `other.disabled.*` and `banners.otherModels.*` keys in `locales/en.json` + `scripts/sync_translation_keys.py` (other locales keep `[TODO: Translate]`).
+
+### 11.5 Cache consistency
+
+- Disabling purges rows from the in-memory view at hydration time (the
+  `_should_keep_cached_entry` hook) and from SQLite on the reconcile triggered by
+  the toggle; the `.metadata.json` sidecars survive, so re-enabling rescans
+  without recomputing hashes (critical for multi-GB text encoders).
+- Enabling triggers a reconcile so newly managed roots are scanned immediately.
+- Editing `settings.json` while the server is stopped is still covered by the
+  hydration hook, so disabled types never appear after a restart.
+
+### 11.6 Tests
+
+Backend: opt-in fixtures added to the other-related suites; new coverage for
+"default off scans nothing", per-sub_type gating, routing/download rejection,
+`_should_keep_cached_entry`, settings normalization and `other_disabled` page
+context. Frontend: `updateOtherModelsControls` / `saveEnabledOtherSubTypes` and
+the disabled-page enable flow.

+# CivitAI image imports can end up with 0 LoRAs
+
+## Symptom
+
+Importing a CivitAI image URL can produce a recipe with **zero LoRA
+entries**, even though the image page lists LoRAs in its resource panel.
+
+Reported example: `https://civitai.red/images/140818889` was imported as a
+local recipe with 0 LoRAs, while the page shows 3 LoRAs. Some images (e.g.
+NSFW / higher browsing level) additionally require a login to view, so their
+data is not publicly reachable at all.
+
+## Root cause
+
+URL imports use only two data sources:
+
+1. **CivitAI REST image API** — `GET /api/v1/images?imageId=<id>&nsfw=X&withMeta=true` → `meta`
+2. **Embedded image metadata** — EXIF/XMP read from the downloaded bytes
+
+For the same image both sources can be empty, and the one source that does
+contain the data is never queried. Verified for image 140818889:
+
+| Source | What it returned |
+|---|---|
+| REST image API | `meta` holds only a prompt; `modelVersionIds: []`; no `resources`/`hashes`; `baseModel: null` |
+| Downloaded image | PNG with **no EXIF/XMP** (the CDN URL ends in `.jpeg`, the body is PNG) |
+| Image page HTML | `__NEXT_DATA__` embeds the trpc `image.getGenerationData` result → full `resources` list: 3 LoRAs, each with `modelId`, `modelVersionId`, `modelName`, `modelType`, `versionName`, `baseModel` |
+
+Key points:
+
+- The page's resource panel is fed by an **internal, non-public trpc
+  endpoint**, not by the public REST image API.
+- That internal endpoint is **login-gated** for some content — the
+  "requires login" symptom.
+- Even with the version IDs in hand, `/model-versions/{id}` for these
+  (Krea) versions returns **no `sha256`**, so an exact local-file hash match
+  is impossible; only model/version identity is recoverable.
+
+## Conclusion / status
+
+0-LoRA imports are a data-source gap: public REST meta and image EXIF are
+both empty, while the only complete source (page generation data) is
+internal, sometimes login-gated, and not used by the importer.
+
+Such imports **cannot be reliably auto-repaired/completed** by the backend
+alone. The old "Repair Metadata" feature only re-fetched the same incomplete
+REST meta and could not fix them; it was deprecated and has been removed.
+
+**Fixed via the companion browser extension.** When the extension is
+installed with a valid license, it scrapes the image page's internal trpc
+generation data with the user's session and calls the payload-capable
+re-import endpoint (`POST /api/lm/recipe/{recipe_id}/reimport` with
+`image_url`/`name`/`resources`/`gen_params`/`base_model`/`tags` query
+params), which rebuilds the recipe from the caller-supplied metadata. The
+web UI delegates re-import of CivitAI-image-sourced recipes to the extension
+automatically (probe + `lm:reimport*` DOM events); without the extension,
+re-import silently falls back to the native path, which remains limited by
+the data-source gap documented above.

+# Reconcile 的 Windows 大小写回退分支 - 待验证清单
+
+> **状态**: 待 Windows 环境验证 | **创建日期**: 2026-09-11
+> **相关文件**: `py/services/model_scanner.py` (`ModelScanner._reconcile_cache`)
+> **相关历史**: #871 (`76ee59cd`, 路径重叠去重)、#1108 (按文件夹扫描的需求)
+
+---
+
+## 背景
+
+Refresh 按钮走的是 `_reconcile_cache()`（快速增量对账）。2026-09-11 做了一轮性能优化，把两处"预防性"的
+realpath 全量遍历改成按需触发（详见下方"已完成"）。优化后，一次零变更 Refresh 在 5 万文件库上从
+~1400 ms 降到 ~120 ms。
+
+清理过程中发现**唯一一处遗留的可疑点**：Windows 专属的大小写不敏感回退分支。它无法在 Linux 上验证，
+因此单独记录，留待 Windows 机器上确认。
+
+---
+
+## 待验证分支（现状）
+
+`py/services/model_scanner.py` 中 `_reconcile_cache()` 的 walk 循环内：
+
+```python
+# Try case-insensitive match on Windows
+if os.name == 'nt':
+    lower_path = file_path.lower()
+    matched = False
+    for cached_path in cached_paths:          # 每个未命中文件都全量扫一遍缓存
+        if cached_path.lower() == lower_path:
+            found_paths.add(cached_path)
+            matched = True
+            break
+    if matched:
+        continue
+```
+
+它排在精确匹配（`file_path in cached_paths`）和 realpath 别名匹配之后，只有**未命中**的文件才会走到。
+
+### 为什么可疑
+
+1. **可能不可达**：Windows 上 `os.path.realpath()` 会返回磁盘上的真实大小写，因此"缓存路径大小写与磁盘
+   不一致"的情形，理论上已经被上一步的 realpath 别名匹配覆盖。若如此，这段就是纯冗余代码。
+2. **一旦可达就是 O(N×M)**：每个未命中文件都要遍历全部 `cached_paths` 做小写比较。若某种路径写法让
+   整个库都变成"未命中"（例如缓存里的盘符/大小写形式与 walk 结果系统性不一致），一次 Refresh 会退化
+   成 文件数 × 缓存条目数 次字符串比较，比真实 IO 还贵。
+3. **没有测试覆盖**：`tests/services/test_model_scanner.py` 没有任何针对该分支的用例（它在 Linux 上
+   被 `os.name == 'nt'` 短路，无法覆盖）。
+
+---
+
+## 待办
+
+- [ ] **验证可达性**：在 Windows 上构造"缓存路径与磁盘真实大小写不一致"的场景，确认 realpath 别名匹配
+      是否已经命中，即上面的 `if os.name == 'nt'` 分支是否还有进入的必要。
+- [ ] **若不可达 / 冗余**：删除该分支，并在删除处留注释说明 realpath 已覆盖大小写归一（附验证记录）。
+- [ ] **若可达**：保留语义但改成 O(1)——预先构建一次 `lower_path -> cached_path` 映射（与
+      `cached_real_paths` 同样按需、懒构建），把内层全量扫描换成一次字典查询。
+- [ ] **补一个 Windows-only 的回归测试**（`pytest.mark.skipif(os.name != "nt", ...)`），锁定最终结论。
+- [ ] 把验证结论回填到本文件，并同步更新状态行。
+
+---
+
+## 验证方法（Windows）
+
+1. **构造不一致的大小写**：让缓存里的 `file_path` 与磁盘实际路径大小写不同（例如改过盘符/目录大小写，
+   或从另一台机器迁移了 `settings.json` 与持久化缓存），然后在 UI 点 Refresh。
+2. **看后端日志判据**：
+   - 若 realpath 已覆盖 → 日志应显示 `Cache reconciliation completed in X seconds. Added 0, removed 0 models.`，
+     且**没有** `Found N new files to process` / `Processing <path>`。
+   - 若回退分支在起作用 → 同样应该是 `Added 0, removed 0`（因为 `found_paths` 被补上），这是"分支可达"
+     的证据；反之若出现大量 `Processing ...` 并重新 hash，说明连回退分支也没命中，问题更严重
+     （缓存路径被当成了新文件 + 旧条目被删）。
+3. **跑测试**：`python -m pytest tests/services/test_model_scanner.py -k reconcile`（该文件在 Windows 上会
+   真实执行 `os.name == 'nt'` 分支）。
+4. **量化**：如果需要，可在 `_reconcile_cache` 里临时插桩统计该分支的进入次数与内层迭代次数，确认是否为 0。
+
+---
+
+## 已完成（本轮优化，供对照）
+
+同一次清理里已经落地并验证的部分（Linux，5 万文件库）：
+
+- `cached_real_paths` 别名映射改为**首次未命中时**懒构建（原来每次 Refresh 都对全部缓存条目算一次 realpath）。
+- 每个文件的 `realpath` 移到精确命中检查**之后**（原来对每个文件都算，命中即丢弃）。
+- `get_model_roots()` 在新增文件处理阶段只快照一次（原来每个新文件重读一次）。
+- 全量去重 pass 加了 O(1) 前置判断（`cached_size_before != len(cached_paths) or total_added > 0`），
+  零变更且缓存干净时跳过；快照本身含重复路径时仍会自愈。
+
+结果：零变更 Refresh 5 万文件 **~1400 ms → ~120 ms**；根目录顺序/符号链接别名翻转场景仍是
+`re-processed=0`（不重新读 metadata、不重新 hash）。测试：`tests/services/test_model_scanner.py`
+47 项、全量后端 2567 项全部通过。

+"""Process-wide, per-destination rate-limit gate for outbound API traffic.
+
+Implements the pacing/gating layer designed in
+``docs/plans/issue-1085-rate-limit-design.md``:
+
+- **Reactive gate**: a 429 response arms ``next_allowed_send`` from the
+  vendor's ``Retry-After`` (or exponential backoff when the header is
+  missing); subsequent requests to the same destination wait out the window.
+- **Preemptive pacing**: a minimum inter-request interval per destination
+  spaces consecutive sends so bursts never form in the first place.
+- **Herd-free**: waiters are serialized through a per-destination lock, so
+  each one claims a distinct send slot instead of thousands of coroutines
+  waking up together.
+- **Bounded**: waits longer than ``rate_limit_max_wait_seconds`` are refused
+  by raising :class:`RateLimitError`, leaving the final decision to callers.
