feat: native disable/enable fallback and package whitelist; bump to 1.8.0

Disable/enable no longer require ComfyUI Manager:
- New pack_fs.py moves packs in/out of custom_nodes/.disabled/ (no import,
  delete, or re-clone). Fallback for hand-cloned packs, loose single-file
  nodes, or when Manager is absent. enable strips the @version suffix so
  packs restore as clean, importable dir names.
- Routes: native-disable, native-enable, disabled-packs.
- Frontend routes each disable per-pack (Manager queue vs native move), and
  shows an Enable button on recoverable packs in the Uninstalled tier. The
  restart banner degrades to a manual-restart notice when no Manager exists.

Whitelist (packages-only): a star toggle protects a pack — pulled into its
own pinned group, no Disable button, skipped by the 7-day trial auto-disable.
- New whitelist_packages table; whitelisted flag on package stats.
- Routes: whitelist, whitelist/add, whitelist/remove.

Tests: test_pack_fs.py, test_whitelist.py (60 passing).

+
+### Workflow tab & temporary enable
+
+Whenever you load a workflow, the extension scans for node types the running
+ComfyUI can't resolve and, if any are found, opens the dialog on the **Workflow**
+tab. Unresolved nodes are split into two groups:
+
+- **Missing** — the owning package isn't installed. Each row offers:
+  - **Install 7d** — really install the package (via
+    [ComfyUI Manager](https://github.com/ltdrdata/ComfyUI-Manager)) and start a
+    *temporary trial*, so trying out someone else's workflow stays
+    non-committal — anything you don't actually use auto-disables.
+  - **Install** — install permanently (no trial).
+
+  Both take effect after a ComfyUI restart. If the install can't be resolved or
+  Manager refuses it (e.g. a blocked git URL), the buttons fall back to opening
+  Manager's Custom Nodes Manager (use its *Missing* filter).
+- **Disabled** — the package is installed but currently disabled. Each row offers:
+  - **Enable 7d** — re-enable the package and start a *temporary trial*.
+  - **Enable** — re-enable permanently (no trial).
+
+**The temporary trial** (started by either *Install 7d* or *Enable 7d*) is a
+rolling budget of **7 distinct boot-days**. A
+"boot-day" is counted at most once per calendar day, the first time ComfyUI
+starts that day — so the clock measures days you actually run ComfyUI, not wall
+time. **Any execution that uses the package resets the counter to zero.** If a
+trial package goes its full budget of distinct boot-days without being used, it
+is **auto-disabled on the next UI load** (handed to ComfyUI Manager exactly like
+a manual disable) and the trial is cleared. As with any disable, a ComfyUI
+restart is required to fully unload it.
+
+Re-enabling and auto-disabling both go through ComfyUI Manager, so the whole
+Workflow tab is inert when Manager is not installed (the backend still tracks
+trial state, but no enable/disable actions are offered).
+
+### Mirror search (disabled-pack nodes)
+
+Sometimes you know the node you want exists in a package you've disabled, but you
+don't want to dig through ComfyUI Manager to find it. The **mirror search**
+palette searches across the `class_type` names of *every currently-disabled
+package* and lets you re-enable the owning package right from the results.
+
+- Open it with the **⌕** button in the top menu bar, or press
+  **`Ctrl/Cmd+Shift+D`** (ignored while typing in an input).
+- Type to filter — results are ranked (node-name prefix first, then word-start,
+  substring, finally pack-name matches) and show the `class_type` and its pack.
+- Hover a result (or use ↑/↓) to open a **preview panel** on the right with the
+  owning package's title, author, description, repo link, and the full list of
+  sibling nodes in that pack — the active node highlighted.
+- **Click a node's name** (or *Draw this node*) to render an **imitation node
+  box** — the real input sockets, widget defaults, and output sockets, drawn from
+  a static parse of the disabled pack's source. Since the pack isn't loaded,
+  there's no live definition to render; the backend AST-parses the pack on disk
+  (read-only, never executed) to recover the schema. Works for most packs (~90%);
+  packs that build their node list dynamically fall back to a placeholder box.
+- Each result offers **Enable 7d** (re-enable under a 7-day trial) and **Enable**
+  (re-enable permanently) — in the row and in the preview panel — the same enable
+  path as the Workflow tab.
+- Enabling takes effect after a ComfyUI restart; enabled rows mark
+  *"✓ enabled · restart"*.
+
+The catalog is built once per session by joining ComfyUI Manager's node→pack
+mappings with the disabled packs (matched across dir name, registry id, and repo
+URL), and cached; use the **↻** button to rebuild it. The palette is inert (with
+a clear message) when ComfyUI Manager is absent or there are no disabled packages.

+# Design: Mirror search for disabled-pack nodes
+
+Date: 2026-06-21
+Status: Approved
+
+## Summary
+
+A standalone "mirror search" palette that lets you find nodes belonging to
+currently-**disabled** custom-node packages — without loading those packages
+(which slows ComfyUI boot/runtime). Each result has Enable buttons; enabling
+re-enables the owning package (temporarily or permanently) and takes effect
+after a ComfyUI restart, after which the node appears in ComfyUI's native search.
+
+This runs *alongside* ComfyUI's native node search rather than inside it:
+ComfyUI's frontend is compiled/bundled and exposes no search-provider or
+node-def injection hook, so the native search cannot be extended. A separate
+palette is the only viable design (and matches the request — a "mirror" search).
+
+## Constraints discovered (reconnaissance)
+
+- Native search injection is **not feasible**: bundled frontend, no public hook
+  (`app.registerExtension` offers `nodeCreated`/`beforeRegisterNodeDef` only),
+  and disabled packs never enter `NODE_CLASS_MAPPINGS` / `/object_info`.
+- `/customnode/getmappings?mode=local` returns a registry-wide map keyed by repo
+  URL: `{ <repo_url>: [ [class_type, ...], { title_aux } ] }`. It **does**
+  include the class_type names for every pack, including disabled ones.
+- `/customnode/getlist?mode=local&skip_update=true` lists packs with `state`
+  (`disabled`/`enabled`/`not-installed`), `id`, `version`, `files`,
+  `repository`. There are 73 disabled packs in the reference install.
+- Available metadata for an unloaded node: **class_type name + pack name/title
+  only**. No categories, descriptions, or input/output ports (those require the
+  pack to be loaded).
+
+## Decisions (from brainstorming)
+
+- **Trigger:** dedicated palette opened by a toolbar button + a keyboard
+  shortcut. Not a tab in the Node Stats dialog.
+- **Enable actions:** both "Enable 7d" (rolling trial) and "Enable" (permanent),
+  reusing the trial-enable feature. Takes effect after restart.
+- **Catalog construction:** frontend-only. Fetch getmappings + getlist on first
+  open, join by repo URL, cache in memory for the session, with a refresh
+  affordance. No backend changes.
+- **Scope:** disabled packs only (not the full not-installed registry — that's
+  Manager's job).
+
+## Architecture
+
+All in `js/nodes_stats.js`; no backend changes.
+
+### Catalog
+- `ensureDisabledCatalog()` (cached in a module variable):
+  1. `fetchManagerInfo()` (existing; getlist) → packs with `state === 'disabled'`.
+  2. `fetch('/customnode/getmappings?mode=local')` → build `repoUrl -> [class_types]`.
+  3. Normalize URLs (lowercase, strip trailing `/` and `.git`) on both sides.
+  4. For each disabled pack, look up class_types by its `files[0]`/`repository`;
+     emit `{ class_type, pack: <dir name>, title, enableInfo }` per node.
+- A `refresh()` clears the cache and rebuilds.
+
+### Search/filter (pure functions, for clarity + manual testability)
+- `scoreEntry(entry, queryLower)` → null if no match; else a rank where
+  class_type prefix < word-start < substring, pack-name match ranked lower.
+- `filterCatalog(catalog, query, limit=50)` → sorted, capped list + total count.
+
+### Palette UI
+- `openMirrorSearch()`: ensure catalog; render a modal overlay (reusing the
+  dialog styling helpers) with a text input (autofocused) and a results list.
+- Input `keyup` → re-render rows via `filterCatalog`.
+- Row: `class_type` · `(pack)` · `[Enable 7d]` `[Enable]`.
+- Footer: "<shown>/<total> from <N> disabled packs · enabling needs a restart" +
+  "↻ refresh".
+- Empty/error/inert states handled explicitly.
+
+### Trigger
+- Toolbar button (like the existing Node Stats button), title "Search disabled
+  nodes".
+- Keyboard shortcut: prefer ComfyUI's extension command/keybinding API if
+  available; else a guarded `document` `keydown` listener (default
+  `Ctrl/Cmd+Shift+D`), ignored when focus is in an input/textarea.
+
+### Actions
+- Reuse `handleEnable(pkg, temporary)` from the trial-enable feature:
+  - `[Enable 7d]` → `temporary=true` (Manager enable → `trials/start`).
+  - `[Enable]` → `temporary=false` (Manager enable → `trials/stop`).
+- Reuse the restart banner / toast. After enable, mark the row "enabled ·
+  restart".
+
+## Data flow
+
+```
+setup() -> add toolbar button + register hotkey
+trigger -> openMirrorSearch()
+        -> ensureDisabledCatalog()  (1st time: getmappings + getlist, join, cache)
+        -> render modal (input + results)
+type    -> filterCatalog() -> render rows (instant, in-memory)
+Enable  -> handleEnable(pkg, temp?) -> Manager enable -> trials/start|stop
+        -> restart banner/toast
+refresh -> clear cache -> ensureDisabledCatalog() -> re-render
+```
+
+## Error handling
+
+- ComfyUI Manager absent or getlist/getmappings fails → palette shows a clear
+  message ("ComfyUI Manager not available" / "couldn't load disabled-node
+  list"); the button stays but the palette is inert. No crash.
+- Zero disabled packs → "No disabled packages — nothing to search."
+- Enable failure → existing error toast; row left actionable.
+- URL-join misses for a pack → that pack contributes no rows (logged to
+  console); never throws.
+
+## Testing
+
+- No backend changes → no new pytest.
+- Pure helpers (`scoreEntry`, `filterCatalog`, URL normalization, catalog join)
+  written as small standalone functions; `node --check` for syntax.
+- Manual verification: open palette via button + hotkey; search a known disabled
+  pack's node (e.g. an Inspire-Pack node); Enable 7d → getlist flips to enabled
+  + `/nodes-stats/trials` shows it + restart banner; Enable (permanent) → enabled,
+  no trial row; refresh rebuilds; Manager-absent path shows the inert message.
+
+## Files touched
+
+- `js/nodes_stats.js` — catalog, filter, palette UI, trigger, reuse enable.
+- `README.md`, `pyproject.toml` — docs + version bump.

+# Disabled-Node Mirror Search Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add a standalone "mirror search" palette (toolbar button + hotkey) that searches nodes belonging to currently-disabled custom-node packages and offers Enable 7d / Enable on each result, reusing the trial-enable code.
+
+**Architecture:** Frontend-only, all in `js/nodes_stats.js`. Build an in-memory catalog by joining ComfyUI Manager's `getmappings` (repo-URL → class_type names, registry-wide) with `getlist` (packs whose `state === 'disabled'`), cached per session. A separate modal palette filters the catalog live. Enable actions reuse a shared `enablePackage()` core (extracted from the existing `handleEnable`). No backend changes.
+
+**Tech Stack:** Vanilla JS (ComfyUI frontend extension via `app.registerExtension`), ComfyUI Manager HTTP endpoints, the trial-enable feature already in this file.
+
+**Design doc:** `docs/plans/2026-06-21-mirror-search-design.md`
+
+**Testing note:** No JS test harness exists. "Verify" steps use `node --check` for syntax and explicit browser-console / in-app checks. Pure helpers are written standalone so they can be exercised from the console. After every JS edit run:
+`cp js/nodes_stats.js /tmp/c.mjs && node --check /tmp/c.mjs && echo OK && rm /tmp/c.mjs`
+
+Reuse points already in `js/nodes_stats.js` (confirmed): `fetchManagerInfo()` (getlist → `{dir:{id,version,files,state}}`), `enablePayload()`, `runManagerEnable()`, `managerIsBusy()`, `handleEnable()`, `notify()`, `escapeHtml()`, `escapeAttr()`, `showRestartBanner()`, the toolbar-button mount in `setup()`.
+
+---
+
+### Task 1: Extract shared `enablePackage()` core (refactor, no behavior change)
+
+**Why:** `handleEnable` is hard-wired to the Workflow tab's `_lastWorkflowScan` and `dialog`. The palette needs the same enable logic without that coupling. Extract the Manager-enable + trial-route + toast into `enablePackage(pkg, info, temporary)`; keep `handleEnable` as the Workflow-tab wrapper.
+
+**Files:** Modify `js/nodes_stats.js` (around lines 717–746).
+
+**Step 1: Add the shared core** immediately above `handleEnable`:
+
+```js
+// Shared enable core used by the Workflow tab and the mirror search palette.
+// Performs the Manager enable + trial bookkeeping + success toast.
+// Returns true on success, false if Manager was busy. Throws on failure.
+// Caller owns its own busy UI and restart affordance.
+async function enablePackage(pkg, info, temporary) {
+  if (!info) throw new Error("no enable info for " + pkg);
+  if (await managerIsBusy()) {
+    notify("ComfyUI Manager is busy. Please try again in a moment.", "warn");
+    return false;
+  }
+  await runManagerEnable(enablePayload(pkg, info));
+  const route = temporary ? "/nodes-stats/trials/start" : "/nodes-stats/trials/stop";
+  await fetch(route, {
+    method: "POST",
+    headers: { "Content-Type": "application/json" },
+    body: JSON.stringify({ package: pkg }),
+  });
+  notify(`Enabled ${pkg}${temporary ? " for a 7-day trial" : ""}. Restart ComfyUI to apply.`, "success");
+  return true;
+}
+```
+
+**Step 2: Replace the body of `handleEnable`** to delegate:
+
+```js
+async function handleEnable(pkg, temporary, dialog) {
+  const entry = _lastWorkflowScan.disabled.find((d) => d.pkg === pkg);
+  const info = entry && entry.info;
+  if (!info) return;
+  setWorkflowButtonsBusy(dialog, true);
+  try {
+    if (await enablePackage(pkg, info, temporary)) {
+      entry.info.state = "enabled";
+      showRestartBanner(dialog);
+    }
+  } catch (e) {
+    notify("Failed to enable: " + e.message, "error");
+  } finally {
+    setWorkflowButtonsBusy(dialog, false);
+  }
+}
+```
+
+**Step 3: Verify syntax** — run the `node --check` line above. Expected: `OK`.
+
+**Step 4: Verify no behavior change (manual)** — hard-refresh ComfyUI, load a workflow with a disabled node, click Enable 7d in the Workflow tab → still enables + restart banner + `/nodes-stats/trials` shows it. (If you don't want to mutate state, just confirm the buttons still render and the console shows no errors on open.)
+
+**Step 5: Commit**
+
+```bash
+git add js/nodes_stats.js
+git commit -m "refactor: extract enablePackage core from handleEnable"
+```
+
+---
+
+### Task 2: Catalog build — URL normalize + join + cache
+
+**Files:** Modify `js/nodes_stats.js` (add near `fetchManagerInfo`).
+
+**Step 1: Add pure helpers + cached loader:**
+
+```js
+// Normalize a repo URL for joining getmappings keys to getlist pack files.
+function normalizeRepoUrl(url) {
+  return String(url || "").trim().toLowerCase().replace(/\.git$/, "").replace(/\/+$/, "");
+}
+
+// Join Manager's node->pack mappings with the disabled packs from getlist.
+// mappings: { <repoUrl>: [ [class_type,...], {title_aux} ] }  (from getmappings)
+// managerInfo: { <dir>: {id,version,files,state,title?} }       (from fetchManagerInfo)
+// Returns [{ class_type, pack, title, info }] for disabled packs only.
+function buildDisabledCatalog(mappings, managerInfo) {
+  const byUrl = {};
+  for (const [url, entry] of Object.entries(mappings || {})) {
+    const list = entry && entry[0];
+    if (Array.isArray(list)) byUrl[normalizeRepoUrl(url)] = list;
+  }
+  const catalog = [];
+  for (const [dir, info] of Object.entries(managerInfo || {})) {
+    if (!info || info.state !== "disabled") continue;
+    const urls = (info.files && info.files.length ? info.files : [info.repository]).filter(Boolean);
+    let nodes = null;
+    for (const u of urls) {
+      const hit = byUrl[normalizeRepoUrl(u)];
+      if (hit) { nodes = hit; break; }
+    }
+    if (!nodes) { console.debug("[Node Stats] no node map for disabled pack", dir); continue; }
+    const title = info.title || dir;
+    for (const ct of nodes) catalog.push({ class_type: ct, pack: dir, title, info });
+  }
+  return catalog;
+}
+
+let _disabledCatalog = null;   // cached for the session
+async function ensureDisabledCatalog(forceRefresh = false) {
+  if (_disabledCatalog && !forceRefresh) return _disabledCatalog;
+  const managerInfo = await fetchManagerInfo();
+  if (!managerInfo) return null;           // Manager absent
+  let mappings = {};
+  try {
+    const r = await fetch("/customnode/getmappings?mode=local");
+    if (r.ok) mappings = await r.json();
+  } catch { /* fall through -> empty catalog */ }
+  _disabledCatalog = buildDisabledCatalog(mappings, managerInfo);
+  return _disabledCatalog;
+}
+```
+
+**Step 2: Verify syntax** — `node --check` line. Expected `OK`.
+
+**Step 3: Verify the join (browser console)** — hard-refresh ComfyUI, open devtools console:
+
+```js
+// paste: pull the two sources and join, then sanity-check
+const mi = await (await fetch("/customnode/getlist?mode=local&skip_update=true")).json();
+const mp = await (await fetch("/customnode/getmappings?mode=local")).json();
+```
+Then confirm in the app once Task 4 wires it; for now just confirm `getmappings` returns an object and `getlist.node_packs` has `state:'disabled'` entries. Expected: yes (≈73 disabled packs in this install).
+
+**Step 4: Commit**
+
+```bash
+git add js/nodes_stats.js
+git commit -m "feat(search): build disabled-node catalog from getmappings x getlist"
+```
+
+---
+
+### Task 3: Search filter (pure)
+
+**Files:** Modify `js/nodes_stats.js`.
+
+**Step 1: Add ranking + filter:**
+
+```js
+// Rank a catalog entry against a lowercased query. Lower = better; null = no match.
+// class_type prefix (0) < class_type word-start (1) < class_type substring (2)
+// < pack-name match (3). No match -> null.
+function scoreEntry(entry, q) {
+  const name = entry.class_type.toLowerCase();
+  if (name.startsWith(q)) return 0;
+  if (name.split(/[\s_\-./]/).some((w) => w.startsWith(q))) return 1;
+  if (name.includes(q)) return 2;
+  if (entry.pack.toLowerCase().includes(q)) return 3;
+  return null;
+}
+
+// Filter + rank a catalog. Returns { rows, total } where rows is capped at limit.
+function filterCatalog(catalog, query, limit = 50) {
+  const q = String(query || "").trim().toLowerCase();
+  if (!q) return { rows: [], total: 0 };
+  const scored = [];
+  for (const e of catalog) {
+    const s = scoreEntry(e, q);
+    if (s !== null) scored.push([s, e]);
+  }
+  scored.sort((a, b) => a[0] - b[0] || a[1].class_type.localeCompare(b[1].class_type));
+  return { rows: scored.slice(0, limit).map((x) => x[1]), total: scored.length };
+}
+```
+
+**Step 2: Verify syntax** — `node --check`. Expected `OK`.
+
+**Step 3: Verify logic (browser console, after Task 4 exposes catalog, or inline)** — confirm e.g. `filterCatalog([{class_type:"MaskComposite",pack:"masquerade"}], "mask").total === 1` and `scoreEntry({class_type:"MaskComposite",pack:"x"}, "mask") === 0`.
+
+**Step 4: Commit**
+
+```bash
+git add js/nodes_stats.js
+git commit -m "feat(search): catalog ranking + filter helpers"
+```
+
+---
+
+### Task 4: Mirror search palette UI
+
+**Files:** Modify `js/nodes_stats.js`.
+
+**Step 1: Add the palette open/render:**
+
+```js
+async function openMirrorSearch() {
+  const existing = document.getElementById("nodes-stats-mirror");
+  if (existing) { existing.querySelector("#ns-mirror-input")?.focus(); return; }
+
+  const overlay = document.createElement("div");
+  overlay.id = "nodes-stats-mirror";
+  overlay.style.cssText =

+  overlay.addEventListener("click", (e) => { if (e.target === overlay) overlay.remove(); });
+  overlay.addEventListener("keydown", (e) => { if (e.key === "Escape") overlay.remove(); });
+

+```
+
+> If `cssEscape` does not already exist in the file, add the small helper used elsewhere: `function cssEscape(s){return window.CSS&&CSS.escape?CSS.escape(s):String(s).replace(/["\\]/g,"\\$&");}` (check first — the disable feature may already define it).
+
+**Step 2: Verify syntax** — `node --check`. Expected `OK`.
+
+**Step 3: Verify (manual)** — temporarily call `openMirrorSearch()` from the console after hard-refresh. Search a known disabled pack node (e.g. an Inspire-Pack class_type). Expected: results list; clicking Enable 7d enables the pack (verify via `/nodes-stats/trials` and getlist state flip), rows turn into "✓ enabled · restart".
+
+**Step 4: Commit**
+
+```bash
+git add js/nodes_stats.js
+git commit -m "feat(search): mirror search palette UI + enable actions"
+```
+
+---
+
+### Task 5: Toolbar button + keyboard shortcut
+
+**Files:** Modify `js/nodes_stats.js` — inside the existing `setup()` (where the Node Stats button is mounted).
+
+**Step 1: Add a second toolbar button** after the existing Node Stats button mount:
+
+```js
+    const searchBtn = document.createElement("button");
+    searchBtn.textContent = "⌕";
+    searchBtn.title = "Search disabled-pack nodes (Ctrl/Cmd+Shift+D)";
+    searchBtn.className = "comfyui-button comfyui-menu-mobile-collapse";
+    searchBtn.style.cssText = "display:flex;align-items:center;justify-content:center;padding:6px;cursor:pointer;font-size:16px;";
+    searchBtn.onclick = () => openMirrorSearch();
+    if (app.menu?.settingsGroup?.element) app.menu.settingsGroup.element.before(searchBtn);
+    else document.querySelector(".comfy-menu")?.append(searchBtn);
+```
+
+**Step 2: Register the hotkey** (guarded `keydown`, ignores typing contexts) at the end of `setup()`:
+
+```js
+    window.addEventListener("keydown", (e) => {
+      if (!(e.shiftKey && (e.ctrlKey || e.metaKey) && (e.key === "D" || e.key === "d"))) return;
+      const t = e.target;
+      if (t && (t.tagName === "INPUT" || t.tagName === "TEXTAREA" || t.isContentEditable)) return;
+      e.preventDefault();
+      openMirrorSearch();
+    });
+```
+
+> If `Ctrl/Cmd+Shift+D` conflicts with a ComfyUI binding in this build, change the key here (e.g. to `K`) and update both titles.
+
+**Step 3: Verify syntax** — `node --check`. Expected `OK`.
+
+**Step 4: Verify (manual)** — hard-refresh ComfyUI; the ⌕ button appears in the top menu; clicking it and pressing Ctrl/Cmd+Shift+D both open the palette; Esc / click-outside closes it.
+
+**Step 5: Commit**
+
+```bash
+git add js/nodes_stats.js
+git commit -m "feat(search): toolbar button + hotkey to open mirror search"
+```
+
+---
+
+### Task 6: Docs + version bump
+
+**Files:** Modify `README.md`, `pyproject.toml`.
+
+**Step 1:** Add a "Mirror search (disabled-pack nodes)" subsection to the README: what it does, how to open it (⌕ button / Ctrl/Cmd+Shift+D), that results come from disabled packs, that Enable 7d/Enable take effect after restart, and that it's inert without ComfyUI Manager. Add a feature bullet.
+
+**Step 2:** Bump `version` in `pyproject.toml` to `1.4.0`.
+
+**Step 3: Verify** — `python -m pytest -q` (unchanged, still green) and the `node --check` line (`OK`).
+
+**Step 4: Commit**
+
+```bash
+git add README.md pyproject.toml
+git commit -m "docs: document mirror search; bump to 1.4.0"
+```
+
+---
+
+## Done criteria
+
+- ⌕ button + Ctrl/Cmd+Shift+D open a palette that searches nodes of disabled packs (joined from getmappings × getlist), cached per session with a refresh.
+- Typing filters instantly (ranked); results show `class_type` + pack with Enable 7d / Enable.
+- Enabling reuses `enablePackage` → Manager enable + trial start/stop + "restart to apply" toast; rows mark "✓ enabled · restart".
+- Workflow-tab enable still works (shared core, no regression).
+- Inert + clear message when ComfyUI Manager is absent or there are no disabled packs.
+- `python -m pytest -q` green; `node --check` clean.

+# Design: Workflow tab + temporary trial-enable for disabled packages
+
+Date: 2026-06-21
+Status: Approved
+
+## Summary
+
+When a loaded workflow references node types that aren't currently resolvable,
+Node Stats shows a **Workflow** tab that splits them into:
+
+- **Missing** — the owning package is not installed (or unknown). Handled by
+  ComfyUI Manager as usual (install).
+- **Disabled** — the owning package is installed but disabled (in
+  `custom_nodes/.disabled`). Offers two actions:
+  - **Enable temporarily** — re-enable the package under a rolling 7-day trial.
+  - **Enable permanently** — normal re-enable, never auto-disabled.
+
+A temporarily-enabled package auto-disables again if it goes **7 distinct
+boot-days without being used** in an executed prompt. Any execution use resets
+the counter back to 7 (rolling window), so a package stays enabled as long as it
+keeps getting used.
+
+## Decisions (from brainstorming)
+
+- **Graduation model:** rolling. Each execution use resets the counter to the
+  full budget (7). 7 distinct boot-days unused → auto-disable. No permanent
+  "graduation"; a trial package stays trial-managed, kept alive by use.
+- **"Used" means:** the package's node appears in an *executed/queued* prompt.
+  Reuses the existing usage tracking. Loading a workflow does not count.
+- **Granularity:** the tab lists individual node types ("list by node"), but
+  every action resolves to and operates on the owning *package* (Manager works
+  per package). Trial state is tracked per package.
+- **Surfacing:** on workflow load, if any node is disabled/missing, auto-open
+  the Node Stats dialog to the Workflow tab.
+- **Disabled actions:** both "Enable temporarily" (trial) and "Enable
+  permanently".
+- **Missing:** defer to ComfyUI Manager (install), as usual.
+- **Orchestration (Approach A):** the Python backend only tracks trial state,
+  counts boot-days, resets on use, and flags expiry. The frontend performs all
+  ComfyUI-Manager enable/disable mutations (server is up, reuses the proven
+  disable code, no coupling to Manager internals). Day-counting stays accurate
+  across headless restarts; the actual auto-disable executes the next time the
+  web UI loads.
+
+## Data model
+
+New SQLite table `trial_packages` in the existing DB:
+
+| column | meaning |
+|---|---|
+| `package` (PK) | directory name (matches our package keys) |
+| `enabled_at` | ISO timestamp the trial started |
+| `last_use_day` | `YYYY-MM-DD` of last execution use (init = enable day) |
+| `last_boot_day` | `YYYY-MM-DD` of last boot-day counted |
+| `unused_boot_days` | counter, 0..budget |
+| `budget` | distinct boot-days allowed unused (default 7) |
+
+### Lifecycle
+
+- **Start trial** (after frontend temp-enable): upsert with
+  `unused_boot_days=0`, `last_boot_day=today`, `last_use_day=today`,
+  `enabled_at=now`. The enable day never counts toward expiry ("not the same
+  day").
+- **Boot tick** (`tracker.tick_boot_days()`, called once at `__init__` import):
+  for each trial row, if `last_boot_day != today`: `unused_boot_days += 1`,
+  `last_boot_day = today`.
+- **Expiry:** computed, not stored — `expired = unused_boot_days >= budget`.
+- **Use reset** (`reset_trials_for(packages)`, called from `_record_prompt`
+  after `record_usage`): for each used package on trial, set
+  `unused_boot_days = 0`, `last_use_day = today`.
+- **Stop trial** (`stop_trial(package)`): delete the row. Called after permanent
+  enable, after the frontend disables an expired pack, or if re-disabled.
+
+Disabling an already-disabled package via Manager is a no-op, so a stale trial
+row (e.g. package disabled out-of-band) resolves cleanly on next expiry pass.
+
+## Backend (Python)
+
+- `tracker.py`: add table to `SCHEMA`; methods `start_trial`, `stop_trial`,
+  `tick_boot_days`, `reset_trials_for(packages)`, `get_trials`.
+- `__init__.py`:
+  - At import: `tracker.tick_boot_days()` wrapped in try/except (never blocks
+    extension load).
+  - In `_record_prompt`: after `record_usage`, map used class_types → packages
+    and call `tracker.reset_trials_for(packages)`.
+  - Routes:
+    - `GET /nodes-stats/trials` → `[{package, unused_boot_days, budget,
+      days_remaining, expired, enabled_at, last_use_day}, ...]`
+    - `POST /nodes-stats/trials/start` `{package}` → upsert trial
+    - `POST /nodes-stats/trials/stop` `{package}` → delete trial
+
+The backend never calls ComfyUI Manager.
+
+## Frontend (JS)
+
+- **WF-load hook:** wrap `app.loadGraphData` (and/or graph-changed event);
+  collect node types present in the graph but not in
+  `LiteGraph.registered_node_types` (unresolved).
+- **Classify** unresolved types using:
+  - `/customnode/getmappings?mode=local` → class_type → pack key
+  - `/customnode/getlist?mode=local&skip_update=true` → pack install state
+  - pack state `disabled` → Disabled bucket; `not-installed`/unmappable →
+    Missing bucket. (Reconcile the getmappings pack key against getlist entries
+    by id/cnr_id/aux_id — verify field names during implementation.)
+- **Workflow tab**, auto-opened when ≥1 unresolved node:
+  - Disabled rows (by node): `[Enable 7d]` (temp → Manager enable, then
+    `trials/start`), `[Enable]` (permanent → Manager enable, then `trials/stop`
+    if previously on trial). Show "on trial — N day-boots left" when applicable.
+  - Missing rows (by node): `[Install]` → defer to Manager install.
+  - Actions resolve to the owning package and dedupe.
+- **Expiry execution:** on app load / dialog open, `GET /nodes-stats/trials`;
+  for `expired` packs, disable via Manager (reuse existing disable code) →
+  `trials/stop` → toast "auto-disabled N unused trial package(s)".
+- Enable/disable need a restart to apply in the running session → reuse the
+  existing restart banner.
+
+## Error handling
+
+- ComfyUI Manager absent → feature inert (no classification, no actions), same
+  as the existing disable feature.
+- HTTP/DB failures → toast + log; never corrupt trial state. Failed expiry
+  disable keeps the row for a later session (retry).
+- Package disabled out-of-band → expiry disable no-ops; row cleaned on stop.
+
+## Testing
+
+- `tests/test_trials.py` (pure logic, mocked dates like existing tests):
+  - start_trial initializes counters; enable day not counted
+  - tick_boot_days increments only on a new calendar day (same-day reboots = 1)
+  - reset_trials_for zeroes the counter
+  - expiry triggers at `unused_boot_days >= budget`
+  - start/stop/get round-trips
+- Frontend verified manually (graph load → tab → enable/disable → expiry).
+
+## Known implementation risk
+
+The **enable** payload (`/manager/queue/install` + `skip_post_install=true`)
+needs the correct `id`/`version` for disabled packs — the same class of detail
+as the disable-payload bug already fixed. Verify empirically against a live
+disabled package during implementation rather than assuming.

+# Workflow Tab + Temporary Trial-Enable Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add a Node Stats "Workflow" tab that splits a loaded workflow's unresolved nodes into Missing (defer to ComfyUI Manager) and Disabled (re-enable temporarily under a 7 distinct-boot-day rolling trial, or permanently), auto-disabling unused trial packages.
+
+**Architecture:** Approach A — the Python backend only tracks trial state in SQLite, counts boot-days (once per `__init__` import), resets a per-package counter when the existing usage tracker sees the package executed, and exposes trial state via three routes. The frontend (JS) detects unresolved graph nodes, classifies them via ComfyUI Manager's `getmappings`/`getlist`, renders the tab, and performs all Manager enable/disable mutations (reusing the existing disable code). The backend never calls Manager.
+
+**Tech Stack:** Python 3.12 (stdlib `sqlite3`), aiohttp routes (ComfyUI `PromptServer`), vanilla JS (ComfyUI frontend extension), pytest.
+
+**Design doc:** `docs/plans/2026-06-21-trial-enable-design.md`
+
+**Reference for date-mocking in tests:** existing `tests/test_model_tracker.py` patches `tracker.datetime`.
+
+---
+
+## Phase 1 — Backend trial state (pure logic, TDD)
+
+All Phase 1 tasks edit `tracker.py` and `tests/test_trials.py`. Run tests with the project's `python -m pytest`.
+
+### Task 1: Trial table + `start_trial` / `get_trials`
+
+**Files:**
+- Modify: `tracker.py` (add to `SCHEMA`, add `DEFAULT_TRIAL_BUDGET`, methods)
+- Create: `tests/test_trials.py`
+
+**Step 1: Write the failing test**
+
+```python
+# tests/test_trials.py
+import pytest
+from datetime import datetime, timezone, timedelta
+from unittest.mock import patch
+from tracker import UsageTracker, DEFAULT_TRIAL_BUDGET
+
+
+@pytest.fixture
+def tracker(tmp_path):
+    return UsageTracker(db_path=str(tmp_path / "test.db"))
+
+
+def test_start_trial_initializes(tracker):
+    tracker.start_trial("Some-Pack")
+    trials = tracker.get_trials()
+    assert len(trials) == 1
+    t = trials[0]
+    assert t["package"] == "Some-Pack"
+    assert t["unused_boot_days"] == 0
+    assert t["budget"] == DEFAULT_TRIAL_BUDGET
+    assert t["days_remaining"] == DEFAULT_TRIAL_BUDGET
+    assert t["expired"] is False
+
+
+def test_start_trial_is_idempotent_resets(tracker):
+    tracker.start_trial("Some-Pack")
+    tracker.start_trial("Some-Pack")
+    assert len(tracker.get_trials()) == 1
+```
+
+**Step 2: Run test to verify it fails**
+
+Run: `python -m pytest tests/test_trials.py -v`
+Expected: FAIL (cannot import `DEFAULT_TRIAL_BUDGET` / no `start_trial`).
+
+**Step 3: Write minimal implementation**
+
+In `tracker.py`, after the `SCHEMA` string add a table (append inside the existing `SCHEMA` triple-quoted block, before the closing `"""`):
+
+```sql
+CREATE TABLE IF NOT EXISTS trial_packages (
+    package TEXT PRIMARY KEY,
+    enabled_at TEXT NOT NULL,
+    last_use_day TEXT NOT NULL,
+    last_boot_day TEXT NOT NULL,
+    unused_boot_days INTEGER NOT NULL DEFAULT 0,
+    budget INTEGER NOT NULL DEFAULT 7
+);
+```
+
+Add a module constant near `EXCLUDED_PACKAGES`:
+
+```python
+DEFAULT_TRIAL_BUDGET = 7
+```
+
+Add methods to `UsageTracker`:
+
+```python
+def start_trial(self, package, budget=DEFAULT_TRIAL_BUDGET):
+    """Begin/restart a temporary-enable trial. The enable day is not counted."""
+    now = datetime.now(timezone.utc)

+        try:
+            conn.row_factory = sqlite3.Row
+            rows = conn.execute(
+                "SELECT package, enabled_at, last_use_day, last_boot_day, "
+                "unused_boot_days, budget FROM trial_packages"
+            ).fetchall()
+        finally:
+            conn.close()
+    result = []
+    for r in rows:
+        d = dict(r)
+        d["days_remaining"] = max(0, d["budget"] - d["unused_boot_days"])
+        d["expired"] = d["unused_boot_days"] >= d["budget"]
+        result.append(d)
+    return result
+```
+
+**Step 4: Run test to verify it passes**
+
+Run: `python -m pytest tests/test_trials.py -v`
+Expected: PASS (2 tests).
+
+**Step 5: Commit**

+## Phase 2 — Wire backend into the server
+
+### Task 5: Boot tick, usage-reset hook, and routes
+
+**Files:**
+- Modify: `__init__.py`
+
+**Step 1: Boot tick at import.** After `model_mapper = ModelMapper()` and before/around the prompt-handler registration, add:
+
+```python
+# Age temporary-enable trials once per process start (one "boot").
+try:
+    tracker.tick_boot_days()
+except Exception:
+    logger.warning("nodes-stats: error ticking trial boot days", exc_info=True)
+```
+
+**Step 2: Reset trials on use.** In `_record_prompt`, after `tracker.record_usage(class_types, mapper)` succeeds, add:
+
+```python
+        try:
+            packages = {mapper.get_package(ct) for ct in class_types}
+            packages.discard("__builtin__")
+            packages.discard("__unknown__")
+            tracker.reset_trials_for(packages)
+        except Exception:
+            logger.warning("nodes-stats: error resetting trials", exc_info=True)
+```
+
+**Step 3: Add routes.** After the existing `reset_stats` route:
+
+```python
+@routes.get("/nodes-stats/trials")
+async def get_trials(request):
+    try:
+        return web.json_response(tracker.get_trials())
+    except Exception:
+        logger.error("nodes-stats: error getting trials", exc_info=True)
+        return web.json_response({"error": "internal error"}, status=500)
+
+
+@routes.post("/nodes-stats/trials/start")
+async def start_trial(request):
+    try:
+        data = await request.json()
+        package = data.get("package")
+        if not package:
+            return web.json_response({"error": "package required"}, status=400)
+        tracker.start_trial(package)
+        return web.json_response({"status": "ok"})
+    except Exception:
+        logger.error("nodes-stats: error starting trial", exc_info=True)
+        return web.json_response({"error": "internal error"}, status=500)
+
+
+@routes.post("/nodes-stats/trials/stop")
+async def stop_trial(request):
+    try:
+        data = await request.json()
+        package = data.get("package")
+        if not package:
+            return web.json_response({"error": "package required"}, status=400)
+        tracker.stop_trial(package)
+        return web.json_response({"status": "ok"})
+    except Exception:
+        logger.error("nodes-stats: error stopping trial", exc_info=True)
+        return web.json_response({"error": "internal error"}, status=500)
+```
+
+**Step 4: Verify import doesn't break.**
+
+Run: `python -c "import ast; ast.parse(open('__init__.py').read()); print('OK')"`
+Expected: `OK`. Then `python -m pytest -q` → all green (existing + trial tests).
+
+**Step 5: Commit**
+
+```bash
+git add __init__.py
+git commit -m "feat(trials): boot tick, usage reset hook, and trial routes"
+```
+
+---
+
+## Phase 3 — Verify Manager enable payload (spike)
+
+### Task 6: Empirically confirm the enable payload for a disabled pack
+
+**Why:** the disable bug taught us not to assume Manager's payload shape. Enable goes through `/manager/queue/install` with `skip_post_install=true`.
+
+**Files:** none (investigation; document findings in this plan / a code comment).
+
+**Step 1:** Pick a currently-disabled pack from the live server (port 8189 in this environment; adjust if changed):
+
+Run:
+```bash
+curl -s "http://127.0.0.1:8189/customnode/getlist?mode=local&skip_update=true" \
+ | python3 -c "import sys,json; d=json.load(sys.stdin); [print(k, {x:v.get(x) for x in ('id','version','files','state')}) for k,v in d['node_packs'].items() if v.get('state')=='disabled'][:5]"
+```
+Expected: rows with `state='disabled'` and their `id`/`version`/`files`.
+
+**Step 2:** Enable one via the install queue mirroring Manager's UI, then verify it flips to `enabled`:
+
+```bash
+# Use the id/version/files from Step 1 for ONE pack:
+curl -s -XPOST "http://127.0.0.1:8189/manager/queue/reset" -H 'Content-Type: application/json'
+curl -s -XPOST "http://127.0.0.1:8189/manager/queue/install" -H 'Content-Type: application/json' \
+  -d '{"id":"<ID>","version":"<VERSION>","files":<FILES_JSON>,"channel":"default","mode":"cache","skip_post_install":true,"selected_version":"<VERSION>","ui_id":"<ID>"}'
+curl -s -XPOST "http://127.0.0.1:8189/manager/queue/start" -H 'Content-Type: application/json'
+# poll status, then re-check getlist state for that pack == 'enabled'
+```
+Expected: pack state becomes `enabled` (restart still required to load it).
+
+**Step 3:** Record the exact minimal working payload as a comment to reuse in the frontend (`enablePayload`). Likely `{id, version, files?, channel, mode, skip_post_install:true, selected_version, ui_id}`. Note any field that turned out load-bearing.
+
+**Step 4:** (optional) revert the test enable via the disable endpoint so state is unchanged.
+
+**No commit** (investigation only). Carry findings into Task 9.
+
+---
+
+## Phase 4 — Frontend (manual verification; no JS test harness)
+
+All Phase 4 tasks edit `js/nodes_stats.js`. After each, hard-refresh the browser (Ctrl+Shift+R) and verify in ComfyUI. Sanity-check syntax after each edit:
+`cp js/nodes_stats.js /tmp/c.mjs && node --check /tmp/c.mjs && rm /tmp/c.mjs`.
+
+### Task 7: Detect unresolved node types on workflow load
+
+**Step 1:** Add a helper that returns the set of node types in the current graph not registered in LiteGraph:
+
+```js
+function unresolvedNodeTypes() {
+  const types = new Set();
+  const nodes = app.graph?._nodes || [];
+  for (const n of nodes) {
+    const t = n.type;
+    if (t && !LiteGraph.registered_node_types[t]) types.add(t);
+  }
+  return [...types];
+}
+```
+
+**Step 2:** Hook workflow load by wrapping `app.loadGraphData` in `setup()`:
+
+```js
+const origLoad = app.loadGraphData?.bind(app);
+if (origLoad) {
+  app.loadGraphData = function (...args) {
+    const r = origLoad(...args);
+    setTimeout(() => onWorkflowLoaded(), 0);  // after graph settles
+    return r;
+  };
+}
+```
+
+**Step 3:** Stub `onWorkflowLoaded` to log for now:
+
+```js
+async function onWorkflowLoaded() {
+  const unresolved = unresolvedNodeTypes();
+  if (unresolved.length) console.log("[Node Stats] unresolved:", unresolved);
+}
+```
+
+**Verify:** load a workflow containing a disabled pack's node → console lists the type(s). **Commit.**
+
+### Task 8: Classify unresolved types into Disabled vs Missing
+
+**Step 1:** Fetch and build the class_type → pack map and pack states. Add:
+
+```js
+async function classifyUnresolved(types) {
+  if (!types.length) return { disabled: [], missing: [] };
+  let mappings = {}, managerInfo = null;
+  try {
+    const [mResp, gi] = await Promise.all([
+      fetch("/customnode/getmappings?mode=local"),
+      fetchManagerInfo(),  // existing: getlist -> {dir: {id,version,files,state}}
+    ]);
+    if (mResp.ok) mappings = await mResp.json();
+    managerInfo = gi;
+  } catch { /* manager absent */ }
+
+  // class_type -> packKey (getmappings value is [ [class_types...], {meta} ])
+  const typeToPack = {};
+  for (const [packKey, entry] of Object.entries(mappings)) {
+    for (const ct of (entry?.[0] || [])) typeToPack[ct] = packKey;
+  }
+  // index managerInfo by id/cnr_id/aux_id as well as dir-name key
+  const byAnyKey = {};
+  if (managerInfo) for (const [dir, info] of Object.entries(managerInfo)) {
+    byAnyKey[dir] = info;
+    for (const k of [info.id, info.cnr_id, info.aux_id]) if (k) byAnyKey[k] = { ...info, _dir: dir };
+  }
+  const disabled = [], missing = [];
+  for (const ct of types) {
+    const packKey = typeToPack[ct];
+    const info = packKey ? byAnyKey[packKey] : null;
+    if (info && info.state === "disabled") disabled.push({ type: ct, pkg: info._dir || packKey, info });
+    else missing.push({ type: ct, pkg: packKey || null });
+  }
+  return { disabled, missing };
+}
+```
+
+> Note (from Task 6): confirm `managerInfo` entries actually expose `cnr_id`/`aux_id`; if not, extend `fetchManagerInfo` to keep them so the getmappings key reconciles. `fetchManagerInfo` currently keeps `{id, version, files, state}` — add `cnr_id`/`aux_id` if present in getlist.
+
+**Verify:** in console, call the classifier on `unresolvedNodeTypes()` for a workflow with a disabled pack → it lands in `disabled`. **Commit.**
+
+### Task 9: Workflow tab UI + auto-open
+
+**Step 1:** Add a third tab button `#ns-tab-workflow` next to Nodes/Models in `showStatsDialog`, a `#ns-content-workflow` container, and extend `switchTab` to handle `"workflow"`.
+
+**Step 2:** Build the tab content from a classification result:
+
+```js
+function buildWorkflowTabContent({ disabled, missing }, trials) {
+  const trialByPkg = Object.fromEntries((trials || []).map(t => [t.package, t]));
+  let html = "";
+  if (!disabled.length && !missing.length) {
+    return `<p style="color:#666;">No missing or disabled nodes in the current workflow.</p>`;
+  }
+  if (disabled.length) {
+    html += sectionHeader("Disabled", "Installed but disabled — re-enable to use", "#e90");
+    html += `<table style="width:100%;border-collapse:collapse;margin-bottom:12px;"><tbody>`;
+    for (const d of disabled) {
+      const t = trialByPkg[d.pkg];
+      const note = t ? `<span style="color:#6a6;font-size:11px;">on trial · ${t.days_remaining}d left</span>` : "";
+      html += `<tr class="ns-row-consider_removing" style="border-bottom:1px solid #222;">
+        <td style="padding:6px 8px;color:#fff;">${escapeHtml(d.type)}</td>
+        <td style="padding:6px 8px;color:#888;">${escapeHtml(d.pkg)} ${note}</td>
+        <td style="padding:6px 8px;text-align:right;white-space:nowrap;">
+          <button class="ns-btn ns-enable-temp-btn" data-pkg="${escapeAttr(d.pkg)}">Enable 7d</button>
+          <button class="ns-btn ns-enable-perm-btn" data-pkg="${escapeAttr(d.pkg)}" style="margin-left:6px;">Enable</button>
+        </td></tr>`;
+    }
+    html += `</tbody></table>`;
+  }
+  if (missing.length) {
+    html += sectionHeader("Missing", "Not installed — install via ComfyUI Manager", "#e44");
+    html += `<table style="width:100%;border-collapse:collapse;margin-bottom:12px;"><tbody>`;
+    for (const m of missing) {
+      html += `<tr class="ns-row-safe_to_remove" style="border-bottom:1px solid #222;">
+        <td style="padding:6px 8px;color:#fff;">${escapeHtml(m.type)}</td>
+        <td style="padding:6px 8px;color:#888;">${m.pkg ? escapeHtml(m.pkg) : "unknown"}</td>
+        <td style="padding:6px 8px;text-align:right;">
+          ${m.pkg ? `<button class="ns-btn ns-install-btn" data-pkg="${escapeAttr(m.pkg)}">Install</button>` : "&mdash;"}
+        </td></tr>`;
+    }
+    html += `</tbody></table>`;
+  }
+  return html;
+}
+```
+
+**Step 3:** Store the latest classification in module scope so `showStatsDialog` can render the tab, and have `onWorkflowLoaded` open the dialog on the Workflow tab when there's ≥1 item:
+
+```js
+let _lastWorkflowScan = { disabled: [], missing: [] };
+async function onWorkflowLoaded() {
+  const types = unresolvedNodeTypes();
+  _lastWorkflowScan = await classifyUnresolved(types);
+  if (_lastWorkflowScan.disabled.length || _lastWorkflowScan.missing.length) {
+    showStatsDialog("workflow");   // showStatsDialog gains an optional initial-tab arg
+  }
+}
+```
+
+**Step 4:** Give `showStatsDialog(initialTab = "nodes")` an optional arg; after building, call `switchTab(initialTab)`; render `buildWorkflowTabContent(_lastWorkflowScan, trials)` where `trials = await fetch('/nodes-stats/trials')`.
+
+**Verify:** load a workflow with a disabled node → dialog auto-opens to Workflow tab listing it. **Commit.**
+
+### Task 10: Enable temporary / permanent actions
+
+**Step 1:** Add `enablePayload(dirName, info)` using the shape confirmed in Task 6, e.g.:
+
+```js
+function enablePayload(dirName, info) {
+  return {
+    id: info.id || dirName, version: info.version, files: info.files,
+    channel: "default", mode: "cache", skip_post_install: true,
+    selected_version: info.version, ui_id: dirName,
+  };
+}
+```
+
+**Step 2:** Add `runManagerEnable(payload)` mirroring `runManagerDisable` but POSTing to `/manager/queue/install`, then `start`, then `waitForQueue()`.
+
+**Step 3:** Wire the buttons (after the dialog is built, alongside `wireDisableButtons`):
+
+```js
+dialog.querySelectorAll(".ns-enable-temp-btn").forEach(b =>
+  b.addEventListener("click", e => { e.stopPropagation(); handleEnable(b.dataset.pkg, true, dialog); }));
+dialog.querySelectorAll(".ns-enable-perm-btn").forEach(b =>
+  b.addEventListener("click", e => { e.stopPropagation(); handleEnable(b.dataset.pkg, false, dialog); }));
+```
+
+**Step 4:** Implement `handleEnable`:
+
+```js
+async function handleEnable(pkg, temporary, dialog) {
+  const info = (_lastWorkflowScan.disabled.find(d => d.pkg === pkg) || {}).info;
+  if (!info) return;
+  setDisableButtonsBusy(dialog, true);
+  try {
+    await runManagerEnable(enablePayload(pkg, info));
+    if (temporary) await fetch("/nodes-stats/trials/start", { method: "POST",
+      headers: { "Content-Type": "application/json" }, body: JSON.stringify({ package: pkg }) });
+    else await fetch("/nodes-stats/trials/stop", { method: "POST",
+      headers: { "Content-Type": "application/json" }, body: JSON.stringify({ package: pkg }) });
+    showRestartBanner(dialog);
+    notify(`Enabled ${pkg}${temporary ? " for a 7-day trial" : ""}. Restart ComfyUI to apply.`, "success");
+  } catch (e) {
+    notify("Failed to enable: " + e.message, "error");
+  } finally {
+    setDisableButtonsBusy(dialog, false);
+  }
+}
+```
+
+**Verify:** click Enable 7d on a disabled node → pack flips to enabled in getlist, `/nodes-stats/trials` shows it, restart banner appears. Click Enable (permanent) on another → enabled, no trial row. **Commit.**
+
+### Task 11: Missing → install via Manager
+
+**Step 1:** Wire `.ns-install-btn` to install the owning pack via Manager. Resolve the pack's getlist entry (it will be `state:'not-installed'` — fetch a fresh getlist or reuse classification info), then POST `/manager/queue/install` with `selected_version:'latest'`, `skip_post_install:false`, start, wait, restart banner.
+
+```js
+async function handleInstall(pkg, dialog) {
+  // fetch the not-installed entry's id/version/files from getlist by pkg key
+  // POST /manager/queue/install {id, version, files, channel:'default', mode:'cache',
+  //   selected_version:'latest', ui_id:pkg}; then start + waitForQueue + restart banner
+}
+```
+
+> Keep this minimal — "handled by Manager like always." If resolving the install entry proves fiddly, fall back to a button that opens ComfyUI Manager's own Install-Missing UI instead of replicating install. Decide during implementation; document the choice.
+
+**Verify:** click Install on a missing node → Manager installs it (or opens its installer). **Commit.**
+
+### Task 12: Execute expiry on load
+
+**Step 1:** Add `processExpiredTrials()` that fetches `/nodes-stats/trials`, and for each `expired` pack: build a disable payload (reuse `disablePayload` with a fresh `fetchManagerInfo` lookup), `runManagerDisable`, then POST `/nodes-stats/trials/stop`. Collect successes for a single toast.
+
+```js
+async function processExpiredTrials() {
+  let trials = [];
+  try { const r = await fetch("/nodes-stats/trials"); if (r.ok) trials = await r.json(); } catch { return; }
+  const expired = trials.filter(t => t.expired);
+  if (!expired.length) return;
+  const mgr = await fetchManagerInfo();
+  if (!mgr) return;
+  const done = [];
+  for (const t of expired) {
+    const info = mgr[t.package];
+    if (!info || info.state === "disabled") { await stopTrial(t.package); done.push(t.package); continue; }
+    try {
+      await runManagerDisable([disablePayload(t.package, info)]);
+      await stopTrial(t.package);
+      done.push(t.package);
+    } catch { /* keep row for next session */ }
+  }
+  if (done.length) notify(`Auto-disabled ${done.length} unused trial package(s). Restart ComfyUI to apply.`, "info");
+}
+```
+
+**Step 2:** Call `processExpiredTrials()` once from `setup()` (after a short delay so the app is ready), guarded so it runs only when Manager is present.
+
+**Verify:** with a trial row forced to `unused_boot_days >= budget` (set via DB or repeated tick), reloading ComfyUI auto-disables that pack and clears the trial. **Commit.**
+
+---
+
+## Phase 5 — Docs & version
+
+### Task 13: README + version bump
+
+**Files:** `README.md`, `pyproject.toml`
+
+**Step 1:** Add a "Workflow tab & temporary enable" subsection to the README (what Missing vs Disabled mean, the 7 distinct-boot-day rolling trial, that use resets it, that auto-disable applies on next UI load and needs a restart). Add a feature bullet. Document the three `/nodes-stats/trials*` endpoints in the API table.
+
+**Step 2:** Bump `version` in `pyproject.toml` to `1.3.0`.
+
+**Step 3:** Run `python -m pytest -q` (all green) and JS `node --check`.
+
+**Step 4: Commit**
+
+```bash
+git add README.md pyproject.toml
+git commit -m "docs: document workflow tab + trial-enable; bump to 1.3.0"
+```
+
+---
+
+## Done criteria
+
+- `python -m pytest -q` green (existing + `tests/test_trials.py`).
+- Loading a workflow with a disabled node auto-opens the Workflow tab; Enable 7d re-enables + records a trial; Enable makes it permanent.
+- A trial package unused for 7 distinct boot-days auto-disables on next UI load; any execution use resets the counter.
+- Missing nodes route to ComfyUI Manager.
+- Feature is inert when ComfyUI Manager is absent.

+# Design: Trial-install (7-day) for missing nodes on workflow load
+
+Date: 2026-06-22
+Status: Approved
+
+## Summary
+
+Extend the existing 7-day rolling trial from *disabled* packages to *missing*
+(not-installed) ones. When a loaded workflow references node types whose owning
+pack isn't installed, the Workflow tab's **Missing** section gains:
+
+- **Install 7d** — really install the pack via ComfyUI Manager, then register a
+  7-day trial. If it isn't used (executed) within 7 distinct boot-days, it
+  auto-disables (moves to `.disabled`, reversible) via the existing expiry path.
+- **Install** — really install the pack permanently (no trial).
+
+This makes trying out someone else's workflow non-committal: pull in what it
+needs, and anything you don't actually use gets parked in `.disabled` instead of
+permanently bloating the install (which slows boot — the whole point of this
+extension).
+
+## Decisions (from clarification)
+
+- **Expiry action:** auto-**disable** (not uninstall). This is free: the trial
+  table is keyed by package and `processExpiredTrials()` already disables any
+  expired trial pack and clears its row. No new expiry code.
+- **Missing-row actions:** both **Install 7d** and **Install** (permanent),
+  symmetric with the Disabled section's Enable 7d / Enable. Both perform real
+  installs from our UI; the current "open ComfyUI Manager" behavior becomes the
+  failure fallback.
+
+## Current state it builds on (v1.6.0, verified)
+
+- `tracker.py`: `trial_packages` table + `start_trial` / `tick_boot_days` /
+  `reset_trials_for` / `stop_trial` / `get_trials`. Boot tick + usage reset +
+  routes (`/nodes-stats/trials[/start|/stop]`) wired in `__init__.py`.
+- `js/nodes_stats.js`:
+  - `classifyUnresolved()` (≈624) → `{ disabled[], missing[] }`; missing entries
+    are `{ type, pkg: <getmappings packKey> }` where packKey is a dir name,
+    registry id, or repo/gist URL.
+  - `handleInstall(pkg, dialog)` (≈1155) currently only opens Manager's Custom
+    Nodes Manager.
+  - `runManagerEnable(payload)` (≈701) = reset → POST `/manager/queue/install`
+    → start → `waitForQueue` (install and enable share this endpoint; only the
+    payload differs).
+  - `processExpiredTrials()` (≈1192) disables expired trial packs via Manager,
+    then `stopTrial`.
+  - `fetchManagerInfo()` (≈483) returns installed/disabled packs only — it
+    **skips** `state==="not-installed"`, so registry data for missing packs is
+    not in hand and must be fetched separately.
+
+## Install resolution (the only real new logic)
+
+Not-installed `getlist` entries expose enough to install (verified live):
+
+- CNR pack: `id` = cnr_id, `version` = semver, `files` = `[git url]`.
+- Git-only pack: no `id`, `version` = `"unknown"`, `files` = `[git url]`.
+
+Plan:
+
+1. **`resolveInstallTarget(packKey)`** — fetch
+   `/customnode/getlist?mode=local&skip_update=true`, index `not-installed`
+   entries by every identifier (key, `id`, `files`, `repository`) with the same
+   normalize used in `classifyUnresolved` (lowercase, strip trailing `/`,
+   `.git`), and return the matching entry (or null).
+2. **`installPayload(entry)`** — mirror Manager's installNodes:
+   `{ id: entry.id || <key>, version: entry.version, files: entry.files,
+   channel:"default", mode:"cache", selected_version: entry.version==="unknown"
+   ? "unknown" : "latest", skip_post_install:false, ui_id:<key> }`.
+3. Install via the existing `runManagerEnable(payload)` (same queue endpoint).
+4. **`findInstalledDir(entry)`** — re-fetch getlist; find the now-installed entry
+   matching `entry` by id/files/repo; its **key is the directory name** (needed
+   to key the trial). Fallback: repo basename of `files[0]` (strip `.git`).
+5. For Install 7d: `POST /nodes-stats/trials/start { package: <dir name> }`.
+6. Show the restart banner: "Installed X — restart to load it" (+ " for a 7-day
+   trial").
+
+## Components (all in `js/nodes_stats.js`)
+
+- `resolveInstallTarget(packKey)`, `installPayload(entry)`, `findInstalledDir(entry)`
+  — small, mostly-pure helpers.
+- `handleTrialInstall(pkg, dialog, temporary)` — orchestrates resolve → install →
+  dir discovery → (trial start if temporary) → restart banner; on any failure
+  falls back to the existing open-Manager behavior of `handleInstall`.
+- Missing rows render `[Install 7d]` + `[Install]`; wire them in
+  `wireWorkflowButtons`. Reuse `setWorkflowButtonsBusy`, `notify`,
+  `showRestartBanner`, `managerIsBusy`.
+
+## Data flow
+
+```
+Workflow tab (missing row)
+  Install 7d -> resolveInstallTarget(packKey) -> installPayload
+             -> runManagerEnable (POST install, start, wait)
+             -> findInstalledDir -> trials/start{dir}
+             -> restart banner "installed for 7-day trial"
+  Install    -> same, minus trials/start
+later boots  -> tracker.tick_boot_days (distinct days)
+use in prompt-> tracker.reset_trials_for (counter -> 0)
+expiry       -> processExpiredTrials (UI load) -> Manager disable + stopTrial
+```
+
+## Error handling
+
+- ComfyUI Manager absent → Missing actions inert (as today).
+- `resolveInstallTarget` miss, install HTTP error, or git-url install blocked by
+  Manager security level → toast + fall back to `handleInstall`'s open-Manager
+  guidance. No crash.
+- `findInstalledDir` returns nothing (install didn't land) → don't register a
+  trial; toast "installed; couldn't register trial — enable/disable manually".
+- `managerIsBusy()` → ask the user to retry (same guard as enable/disable).
+
+## Testing
+
+- Backend unchanged → no new pytest; existing `tests/` stays green.
+- Pure helpers (`resolveInstallTarget` matching, `installPayload`,
+  `findInstalledDir` matching) written standalone; `node --check` for syntax.
+- Manual: load a workflow needing a not-installed CNR pack → Install 7d installs
+  it, `/nodes-stats/trials` shows the resulting dir, restart banner appears;
+  Install (permanent) installs without a trial row; a git-url-only/blocked pack
+  falls back to opening Manager; Manager-absent path inert.
+
+## Files touched
+
+- `js/nodes_stats.js` — resolution helpers, `handleTrialInstall`, Missing-row
+  buttons + wiring.
+- `README.md`, `pyproject.toml` — docs + version bump (1.6.0 → 1.7.0).
+
+## Out of scope (YAGNI)
+
+- Auto-uninstall on expiry (chose disable; reversible + free).
+- Bulk "install all missing 7d" (start per-row; revisit if wanted).
+- Replicating Manager's full dependency/security UX (fall back to Manager).

+# 7-Day Trial-Install for Missing Nodes — Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Let the Workflow tab really install a workflow's missing (not-installed) packs — either permanently or on the existing 7-day rolling trial that auto-disables unused packs.
+
+**Architecture:** Frontend-only (`js/nodes_stats.js`). Resolve a missing pack's install spec from its not-installed `getlist` entry, install via ComfyUI Manager's queue (reusing `runManagerEnable`, which posts to `/manager/queue/install`), discover the resulting directory name by re-reading `getlist`, and register a trial via the existing `/nodes-stats/trials/start`. Expiry (auto-disable) is already handled by `processExpiredTrials()` — no new expiry code. On any failure, fall back to the current open-Manager behavior.
+
+**Tech Stack:** Vanilla JS ComfyUI extension; ComfyUI Manager HTTP endpoints; the trial machinery already shipped in v1.6.0.
+
+**Design doc:** `docs/plans/2026-06-22-trial-install-design.md`
+
+**Testing note:** No JS test harness. After every edit run:
+`cp js/nodes_stats.js /tmp/c.mjs && node --check /tmp/c.mjs && echo OK && rm /tmp/c.mjs`
+Behavior is verified manually in ComfyUI (hard-refresh after each change).
+
+**Confirmed reuse points (v1.6.0, real line numbers):** `classifyUnresolved` (≈624, builds `missing[]`), `buildWorkflowTabContent` Missing section (≈410-422), `wireWorkflowButtons` (≈698), `handleInstall` (≈1155, open-Manager fallback), `runManagerEnable` (≈701, install-queue helper), `processExpiredTrials` (≈1192), `setWorkflowButtonsBusy` (≈1172), `managerIsBusy`, `showRestartBanner`, `notify`, `escapeHtml`, `escapeAttr`.
+
+---
+
+### Task 1: Shared `normKey` + install-resolution helpers
+
+**Files:** Modify `js/nodes_stats.js` (add helpers near `classifyUnresolved`, ~line 620).
+
+**Step 1: Add a module-level `normKey`** (and point `classifyUnresolved`'s local `norm` at it for DRY):
+
+```js
+// Normalize an identifier (dir name, registry id, or repo URL) for matching.
+function normKey(s) {
+  return String(s).trim().replace(/\/+$/, "").replace(/\.git$/i, "").toLowerCase();
+}
+```
+
+In `classifyUnresolved`, replace the local
+`const norm = (s) => String(s).trim().replace(/\/+$/, "").replace(/\.git$/i, "").toLowerCase();`
+with `const norm = normKey;`.
+
+**Step 2: Add the resolver, payload builder, and dir finder:**
+
+```js
+// Find the not-installed getlist entry for a missing pack key (from getmappings).
+// Returns { key, id?, version, files, repository, ... } or null.
+async function resolveInstallTarget(packKey) {
+  let packs;
+  try {
+    const r = await fetch("/customnode/getlist?mode=local&skip_update=true");
+    if (!r.ok) return null;
+    packs = (await r.json()).node_packs;
+  } catch { return null; }
+  if (!packs) return null;
+  const want = normKey(packKey);
+  for (const [key, v] of Object.entries(packs)) {
+    if (!v || v.state !== "not-installed") continue;
+    const ids = [key, v.id, v.repository, ...(v.files || [])].filter(Boolean).map(normKey);
+    if (ids.includes(want)) return { key, ...v };
+  }
+  return null;
+}
+
+// Build the /manager/queue/install payload, mirroring Manager's installNodes.
+function installPayload(entry, packKey) {
+  const unknown = !entry.version || entry.version === "unknown";
+  const id = entry.id || packKey;
+  return {
+    id, version: entry.version || "unknown", files: entry.files,
+    channel: "default", mode: "cache",
+    selected_version: unknown ? "unknown" : "latest",
+    skip_post_install: false, ui_id: id,
+  };
+}
+
+// After install, find the now-installed directory name (the trial key) by
+// re-reading getlist and matching the entry; fall back to the repo basename.
+async function findInstalledDir(entry) {
+  let packs = null;
+  try {
+    const r = await fetch("/customnode/getlist?mode=local&skip_update=true");
+    if (r.ok) packs = (await r.json()).node_packs;
+  } catch { /* fall through to basename */ }
+  if (packs) {
+    const want = [entry.id, entry.repository, ...(entry.files || [])].filter(Boolean).map(normKey);
+    for (const [key, v] of Object.entries(packs)) {
+      if (!v || v.state === "not-installed") continue;
+      const cand = [key, v.id, v.repository, ...(v.files || [])].filter(Boolean).map(normKey);
+      if (cand.some((c) => want.includes(c))) return key; // key = directory name
+    }
+  }
+  const url = (entry.files && entry.files[0]) || entry.repository || "";
+  return url.replace(/\/+$/, "").replace(/\.git$/i, "").split("/").pop() || null;
+}
+```
+
+**Step 3: Verify syntax** — run the `node --check` line. Expected `OK`.
+
+**Step 4: Verify resolver (browser console, after hard-refresh)** — pick a known not-installed pack key from `await (await fetch('/customnode/getlist?mode=local&skip_update=true')).json()` and confirm `resolveInstallTarget(key)` returns it. Expected: the entry with `files`/`version`.
+
+**Step 5: Commit**
+
+```bash
+git add js/nodes_stats.js
+git commit -m "feat(install): install-target resolution helpers for missing packs"
+```
+
+---
+
+### Task 2: `handleTrialInstall` orchestrator
+
+**Files:** Modify `js/nodes_stats.js` (add next to `handleInstall`, ~line 1155).
+
+**Step 1: Add the orchestrator** (keep `handleInstall` as the fallback):
+
+```js
+// Real install of a missing pack, optionally on a 7-day trial. Resolves the
+// install spec, installs via Manager, discovers the resulting directory, and
+// (for a trial) registers it. Falls back to opening Manager on any failure.
+async function handleTrialInstall(pkg, dialog, temporary) {
+  if (await managerIsBusy()) {
+    notify("ComfyUI Manager is busy. Please try again in a moment.", "warn");
+    return;
+  }
+  const target = await resolveInstallTarget(pkg);
+  if (!target) { await handleInstall(pkg, dialog); return; }
+

+
+### Task 3: Missing rows — `Install 7d` + `Install` buttons
+
+**Files:** Modify `js/nodes_stats.js` — `buildWorkflowTabContent` Missing section (~410-422).
+
+**Step 1: Update the subtitle and the action cell.** Replace the section header subtitle "Not installed — install via ComfyUI Manager" with "Not installed — install, optionally on a 7-day trial", and replace the single-button cell:
+
+```js
+        <td style="padding:6px 8px;text-align:right;white-space:nowrap;">
+          ${m.pkg
+            ? `<button class="ns-btn ns-install-temp-btn" data-pkg="${escapeAttr(m.pkg)}">Install 7d</button>
+               <button class="ns-btn ns-install-perm-btn" data-pkg="${escapeAttr(m.pkg)}" style="margin-left:6px;">Install</button>`
+            : "&mdash;"}
+        </td>
+```
+
+**Step 2: Verify syntax** — `node --check`. Expected `OK`.
+
+**Step 3: Commit**
+
+```bash
+git add js/nodes_stats.js
+git commit -m "feat(install): Missing rows offer Install 7d + Install"
+```
+
+---
+
+### Task 4: Wire the new buttons + busy state
+
+**Files:** Modify `js/nodes_stats.js` — `wireWorkflowButtons` (~698) and `setWorkflowButtonsBusy` (~1172).
+
+**Step 1:** In `wireWorkflowButtons`, replace the `.ns-install-btn` wiring with:
+
+```js
+  dialog.querySelectorAll(".ns-install-temp-btn").forEach((b) =>
+    b.addEventListener("click", (e) => { e.stopPropagation(); handleTrialInstall(b.dataset.pkg, dialog, true); }));
+  dialog.querySelectorAll(".ns-install-perm-btn").forEach((b) =>
+    b.addEventListener("click", (e) => { e.stopPropagation(); handleTrialInstall(b.dataset.pkg, dialog, false); }));
+```
+
+**Step 2:** In `setWorkflowButtonsBusy`, update the selector to the new classes:
+
+```js
+  dialog.querySelectorAll(".ns-enable-temp-btn, .ns-enable-perm-btn, .ns-install-temp-btn, .ns-install-perm-btn").forEach((b) => {
+    b.disabled = busy;
+  });
+```
+
+**Step 3: Verify syntax** — `node --check`. Expected `OK`.
+
+**Step 4: Verify (manual)** — hard-refresh; load a workflow that needs a not-installed **CNR** pack (small one, e.g. a simple utility pack). Click **Install 7d** → it installs, restart banner appears, and `await (await fetch('/nodes-stats/trials')).json()` lists the installed dir. Click **Install** on another → installs, no trial row. Try a pack that fails / git-url-blocked → falls back to opening Manager with a toast.
+
+**Step 5: Commit**
+
+```bash
+git add js/nodes_stats.js
+git commit -m "feat(install): wire Install 7d / Install buttons"
+```
+
+---
+
+### Task 5: Docs + version bump
+
+**Files:** Modify `README.md`, `pyproject.toml`.
+
+**Step 1:** In the README's Workflow-tab section, document that Missing nodes can now be installed permanently or on a 7-day trial (auto-disables if unused, takes effect after restart, falls back to ComfyUI Manager on failure). Update any feature bullet.
+
+**Step 2:** Bump `version` in `pyproject.toml` from `1.6.0` to `1.7.0`.
+
+**Step 3: Verify** — `python -m pytest -q` (unchanged, green) and the `node --check` line (`OK`).
+
+**Step 4: Commit**
+
+```bash
+git add README.md pyproject.toml
+git commit -m "docs: document 7-day trial-install for missing nodes; bump to 1.7.0"
+```
+
+---
+
+## Done criteria
+
+- Workflow tab Missing rows show **Install 7d** and **Install**.
+- Install 7d really installs the pack (CNR via registry; git-url where Manager allows) and registers a trial keyed by the installed directory; Install does the same without a trial.
+- Unused trial-installed packs auto-disable on a later UI load via the existing `processExpiredTrials` (no new expiry code); using one resets its 7-day counter.
+- Failures (unresolvable spec, HTTP error, git-url blocked, Manager absent) fall back to opening ComfyUI Manager — no crash.
+- `python -m pytest -q` green; `node --check` clean.
