fix(workspace): revalidate served pages and static files on reload

The workspace pages and every file under /prompt_manager/js and
/prompt_manager/lib went out with no Cache-Control and no validator.
ComfyUI's own cache middleware only fills a missing Cache-Control for
paths ending in .js or .css, so the workspace's .mjs modules got no
header at all, and after an update the browser could keep running old
modules until a hard refresh.

Every page and static file now carries Cache-Control: no-cache and a
weak ETag over its bytes, and a request that already holds that version
gets a 304 without a body. A normal reload picks up new code and stays
cheap when nothing changed.

Closes #478

+### Collections contract (#331)
+
+A collection is a named, hand-picked group of images (milestone 7 "Additional
+organization"). It never copies, moves or changes a file, a prompt, a tag, a category
+or a favorite. Legacy pages have no collections, so the legacy coverage table gains no
+row.
+
+**Database** (`database/image_collections.py`, mixed into `PromptDatabase`):
+- `image_collections(id, name, name_key UNIQUE, created_at)` and
+  `image_collection_items(collection_id → image_collections ON DELETE CASCADE,
+  root_key, relative_path, added_at, PRIMARY KEY (collection_id, root_key,
+  relative_path))`, plus `idx_image_collection_items_file(root_key, relative_path)`.
+  `migrate_image_collections` runs right after the saved-views migration inside its own
+  savepoint, creates the three objects empty with no backfill, changes no existing
+  table and reads only `sqlite_master` and its own tables, so its cost does not depend
+  on library size (checked with an SQLite authorizer on a 23,000-image library; a
+  second run is a no-op). Startup validates structure only; restore runs the full value
+  check.
+- A name is stored as typed after normalization: trimmed, each run of whitespace one
+  space, 1 to 100 characters, no control characters (Unicode `Cc`). `name_key` is
+  `NFC(casefold(NFC(name)))`, so names are unique ignoring case and Unicode form (a
+  macOS NFD name matches the Windows NFC one). Restore checks `name_key` only as
+  non-empty bounded text and does not recompute it: Python's Unicode case tables differ
+  between versions, so a backup made on another Python must still restore.
+- A member names a file by location, exactly as a favorite does: the source folder's
+  real path (`_favorite_root_key`) plus the path below it (`_favorite_relative_key`),
+  case-folded on Windows, each at most 4,096 characters. A case-only rename keeps a
+  Windows member; two Linux files that differ only by case are two members; on macOS a
+  case-only rename hides the member, as it hides a favorite. The Windows folding is
+  tested on every OS through `ntpath`.
+- Each write is one `BEGIN IMMEDIATE` transaction, so two tabs adding the same new
+  name create one collection. A collection is created only when at least one file is
+  inserted.
+
+**Missing members (MC2, MC3):** a member whose file is moved, renamed or deleted
+outside PromptManager, or whose source folder is offline, is hidden and its row kept;
+it shows again when a file appears at the same path (which may be a different image,
+as with favorites). Nothing follows a moved file, and there is no "forget missing"
+cleanup; deleting the collection removes those rows.
+
+**Duplicate cleanup (MC4):** System › Maintenance duplicate files moves the removed
+copy's memberships to the kept copy as a union, in the transaction that moves its
+favorite and image tags, and the job log reads "Moved N collection membership(s) to the
+kept copies". The legacy gallery page's duplicate delete does not move them (as for
+favorites).
+
+**Restore (MC8):** `collections` joins the restore stage's summary keys and
+`image_collections`'s `MAX(rowid)` its fingerprint; membership edits are not
+fingerprinted, as favorite and tag edits are not. A backup made before collections
+restores with no collections (the tables are created empty); the pre-restore safety
+backup keeps the old ones. The restore review shows no collections count.
+
+**Routes** (`py/api/collections.py`; every answer `{"success": bool, ...}`):
+
+| Route | Request | Success |
+| --- | --- | --- |
+| `GET /prompt_manager/collections` | none | `{collections: [{id, name, count, missing}]}` in name-key, then id, order |
+| `POST /prompt_manager/collections/items` | `{collection_id}` or `{name}`, and `items` | `{collection: {id, name}, created, added, already, not_found}` |
+| `DELETE /prompt_manager/collections/items` | `{collection_id, items}` | `{collection: {id, name}, removed}` |
+| `GET /prompt_manager/collections/membership` | query `root_index`, `root_scope`, `path`, each once | `{collection_ids: [...]}` |
+| `PATCH /prompt_manager/collections/{id}` | `{name}` | `{collection: {id, name}}` |
+| `DELETE /prompt_manager/collections/{id}` | none | `{deleted: true}` |
+
+- Ids are `[1-9][0-9]{0,8}` (path) or that int (body); anything else, or a body with
+  both or neither of `collection_id` and `name`, is 400.
+- `items` holds 1 to 500 targets `{root_index, root_scope, path}`, each checked by the
+  shared `py/api/media_target.py` (the image-annotation routes use the same check): 400
+  for a malformed shape, 403 for a traversal, drive, backslash or non-media path. A
+  `root_scope` that no longer names its root is 409 `source-changed` ("The sources
+  changed. Refresh the images and try again."). Any invalid item refuses the request
+  before a write; two targets that fold to one key count once.
+- Add keeps only files the source's listing holds and counts the rest in `not_found`;
+  a new name with nothing inserted is 404 `files-not-found` and creates nothing. A name
+  matching an existing collection ignoring case adds to it. Remove accepts any
+  well-formed target, listed or not.
+- An unknown id is 404 `collection-not-found`; a rename to another collection's name is
+  409 `name-taken` (a case variant of its own name is allowed). Any other failure is a
+  logged 500 with "Collections could not be read." or "The collection could not be
+  changed.", never the exception text.
+- Counts: `count` is the members the current listing of every configured source shows
+  (a folder configured twice counts once), `missing` the stored rows beyond it,
+  clamped at 0. Both come from one read snapshot of every member and stored count, so a
+  write between two reads cannot skew them. When any source's scan or read fails, both
+  are `null` for every collection and the names still return.
+- Every database read and every filesystem call (realpath, the scans) runs in the
+  executor; nothing touches the filesystem on the event loop.
+- The Images listing (`/prompt_manager/images/output?mode=workspace`) accepts
+  `collection` (`""` or an id) among `LISTING_FILTER_KEYS`; the cursor's scope hash
+  includes it, so a cursor from one collection is refused on another. An unknown
+  collection is 404 `collection-not-found`, checked before any per-source read; a
+  failed members read is the listing's 500, never an unfiltered page. A collection and
+  `favorites=1` are never both applied (the collection wins).
+
+**Limits (MC12):** names 1 to 100 characters; at most 500 files per add or remove; no
+limit on the number of collections or members.
+
+**Selection bar and "all N matching" (#331 PR 3 ruling):** the collection routes take
+explicit files only (no listing filter). With "All N matching selected" (D135), Add to
+collection and Remove from collection send the loaded images only when every match is
+loaded and checked and there are at most 500; otherwise they toast "Select at most
+500 images." and open nothing. Over 500 explicitly checked files toast the same.
+
+Recorded deviations:
+- **D136** (amends D28): the concept's COLLECTIONS group (`#collections-nav`,
+  index.html 28–31) without the "PROPOSED" badge. One `links()` row per collection
+  (folder icon, name, `.nav-count`) in name-key order, linking `#/collection/<id>`. The
+  count follows the nav-count rules of D51 (hidden until loaded, absent when it could
+  not be read, never a placeholder) and is re-read 300 ms after the last confirmed add,
+  remove, rename or delete; the list is re-read after a restore. The label is hidden
+  while no collection exists. At 950 px and below the concept hides
+  `#collections-nav`, which would leave a phone no way to open a collection: the rows
+  show in the wrapped nav (`workspace.css`, `/* D136 */`), the label stays hidden as
+  every sidebar label is, and the counts are hidden as on every concept nav row at that
+  width. (Open question for the maintainer: CUJ 15 asks for "with counts" at phone
+  width; production follows the concept's phone rule and hides them.) A failed list
+  read keeps the last rows.
+- **D137**: the collection page `#/collection/<id>` is Images filtered to the
+  collection: the collection's name is the h1, "Collection" the breadcrumb and title
+  (concept a1186–1189), with the concept's Images description and every Images control.
+  Its heading leads with **Edit** ("Edit collection", "Collection name", Delete…
+  (danger), Cancel, Save; the saved views' D51 dialog with collection nouns): "Collection
+  renamed.", a taken name stays in the dialog as "A collection named “X” already
+  exists.", "The collection could not be renamed. Try again." keeps it open. Delete…
+  asks "Delete “X”? Its N images stay where they are; only the collection is removed."
+  (N the stored count) and toasts "Collection deleted." (a 404 counts as deleted),
+  then opens `#/images`; a failure toasts "The collection could not be deleted. Try
+  again.". A `p.small` after the description reads "N image(s) in this collection

+- **D138** (amends D8): **Add to collection** follows Set category and opens the
+  concept's `simpleInput` ("Add selected images to collection", "Collection name")
+  with the action "Add" (the concept's "Apply in prototype"), an empty field (the
+  concept pre-fills its sample "Experiments") of at most 100 characters, and a
+  `datalist` of the existing names (`#action-input-suggestions`; the field is then a
+  combobox, and Chromium draws its suggestion arrow inside the field, which the
+  geometry comparison does not see). An empty field keeps the dialog on it. The toasts: "Added N image(s) to
+  “X”." plus " N was/were already in it." and " N could not be found.", "All selected
+  images were already in “X”.", "None of the selected images could be found. Refresh
+  the images and try again." (404 `files-not-found`), "The sources changed. Refresh
+  the images and try again." (409; the sources and the listing are read again, which
+  clears the selection), "That collection no longer exists." and "The images could not
+  be added. Try again.". Otherwise the selection stays and the listing is not reloaded.
+  **Remove from collection** (beyond the concept) follows Add while a collection filter
+  is active (a collection page or a saved view on one), with no confirmation: "Removed
+  N image(s) from “X”.", then the loaded range is read again in place, keeping the
+  checked files still listed. "That collection no longer exists." (404, a collection
+  deleted meanwhile) reads the listing again, which then shows the deleted-collection
+  page; "The sources changed. Refresh the images and try again." (409) reads the
+  sources and listing again and clears the selection; "The images could not be removed.
+  Try again." keeps everything. A second press while it runs is ignored.
+- **D139** (beyond the concept): the shared inspector's footer ends with
+  **Collections…** (the folder icon) after Prompt history, for a listed file only
+  (`rooted-file` with its scope), in the Images side panel and the viewer's details;
+  Inspect a file and the Prompt library's galleries have no client store and no
+  button. Its dialog "Collections": "Loading collections…" while the file's membership
+  is read ("Collections could not be loaded." with Retry on failure; Save waits), one
+  concept checkbox row (`label.tag-suggestion`) per collection in sidebar order,
+  checked where the file is a member ("No collections yet. Name one below." without
+  any), a "New collection" field (at most 100 characters; a name matching an existing
+  collection adds to it), then Cancel and Save. Focus starts on the field and moves to
+  the first checkbox once they are listed. A typed name equal to a listed collection
+  ignoring case is that collection's checkbox, checked (never an add then a remove); a
+  name that cannot be a collection name is refused on the field with "The collections
+  could not be updated. Try again.", nothing is sent and the checkbox edits stay. Save
+  sends one request per change: the new name, each newly checked collection, each
+  unchecked one; nothing changed sends nothing and closes. All sent: the dialog closes
+  with "Collections updated.". A failure keeps it open with "The collections could not
+  be updated. Try again." and the membership read again, Save waiting until that read
+  lands; × and Escape wait while it saves. The page hears of the changes that went
+  through only when the dialog closes (a failure included), so a reload cannot remove
+  the dialog before its message is read. On a collection page a change to the open
+  collection then reloads the listing at once from the side panel, and from the viewer
+  only when the viewer closes, so the viewer keeps its place (no listing request while
+  it is open). Closing returns focus to the trigger, or, when a re-render replaced it,
+  to the inspector's current Collections… button or its heading. The
+  inspector comparison draws the button into the concept's panel footer and full
+  details after Prompt history (a copy of its Prompt history button with the concept's
+  folder icon), so the browser lays out what follows.
+- **D140**: saved views' Images state gains `collection` (`""` or an id, the `source`
+  encoding); older rows read `""`, and a write with both `favorites: true` and a
+  collection is 400. Save view on a collection page stores the id; the view reopens
+  the collection with its other filters under the view's own name (D51), with Remove
+  from collection and without the missing note. A view whose collection was deleted
+  (MC6) lists nothing and reads "The collection this view uses was deleted."; it never
+  falls back to every image, and the view is not changed.

+### Selecting prompts and Set category (#437)
+
+**D148** (beyond the concept, whose Library cards have no checkbox): the Prompt library
+selects prompts and sets their category in one step, the legacy admin page's bulk "Set
+Category". It is built only from the concept's Images parts:
+
+- Each `article.prompt-card` leads with the Images `.image-overlays > label > input`
+  checkbox ("Select <title>"), placed by the concept's overlay CSS over the art; the card
+  carries `position: relative` (the concept puts it on `.media-art`). The checkbox comes
+  before the title in tab order (on Images it follows the image button). Tab and
+  Shift+Tab across windowed cards reach it (the card's controls are `button,
+  input[type=checkbox]`); Home, End and the arrow keys still move between titles.
+- `div#library-bulkbar` sits between the toolbar and the caption, empty until something
+  is checked, then the concept's `.bulkbar`: "N selected", Set category, Clear (D151
+  adds Add tags before Set category, in the Images bar's order). The
+  selection is a set of prompt ids over the loaded shelf: windowed-out cards keep their
+  state, Load more keeps it, and any shelf reload (search, category, sort, tags, a
+  write) and leaving the page clear it. Clicking a checkbox toggles it and sets the
+  anchor; Shift+click applies the anchor's range with the box's new state (the D135
+  helpers). Escape in the bar and Clear clear it, focus to the heading. There is no
+  Shift+arrow, long-press or "Select all N matching" on the Library (D151 adds
+  Ctrl/Cmd+A and "Select all N loaded").
+- Set category opens the shared `simpleInput` dialog ("Categorize selected prompts",
+  `input#action-input` labelled Category, at most 100 characters, the Library's
+  categories as suggestions). A blank value keeps it open; a control character is
+  refused on the field ("A category cannot contain control characters."). More than
+  1,000 selected toasts "Select at most 1,000 prompts." and opens nothing.
+- Apply posts `{prompt_ids, category, expected_epoch}` to `POST
+  /prompt_manager/bulk/category`, the epoch being the shelf's first page's
+  `library_epoch` (kept with a returning visit; a later page from another epoch is a
+  shelf error). The server checks the epoch, then sets the category on the Library
+  parents among the ids in one `BEGIN IMMEDIATE` transaction, writing (and registering as
+  Library parents, as the editor's PATCH does) only rows whose category differs, and
+  answers `{library_epoch, category, updated, unchanged, not_found}`. A restored storage
+  answers 409 `storage-changed` and writes nothing. The legacy `{prompt_ids, category}`
+  and `{images_filter, category}` bodies are unchanged.
+- Outcomes: "Category “X” set on N prompts." (plus "M could not be found."), then the
+  shelf and its categories reload and cached Library views and the sidebar counts are
+  invalidated, also when the page was left during the write. None found: "None of the
+  selected prompts could be found. The Library was reloaded." Storage restored: "Prompt
+  storage was restored since this page loaded. No category was changed." and a reload.
+  No answer, 502, 503 or 504: "The category change could not be confirmed. The Library
+  was reloaded." Any other refusal: "Category could not be set. Try again.", the
+  selection kept. Every bar action (and D151's select-all offer) is `aria-disabled` while
+  a write runs.
+- The bar's DOM and write loop live in `library-selection.mjs`; the toast text
+  (`setOutcome` with the noun "prompt"), the range helpers, the count and the dialog are
+  the Images bar's. One bar core shared with `images-selection.mjs` is a follow-up.
+
+Tests: `tests/browser/workspace-library-selection.spec.mjs` (set, blank and control
+characters, Clear/Escape/filter, Shift+click range and Tab across the window edge, the
+fence after a return visit, an unseen restore, refused and unconfirmed writes);
+`tests/browser/library-concept.spec.mjs` ("the Library selection checkbox and bar match
+the concept's Images ones", 1600x1100 and 390x844, both themes, with a moved-checkbox
+mutation); units `tests/js/workspace-library-selection.test.js`,
+`tests/js/workspace-library-state.test.js` (the epoch); Python
+`tests/test_bulk_library_category.py`. A Python change: ComfyUI needs a restart.
+
+### Adding tags to selected prompts and selecting all (#442)
+
+**D151** (beyond the concept, on D148's bar): the Prompt library adds tags to the selected
+prompts in one step, the legacy admin page's bulk "Add Tags", and selects every loaded
+prompt, as its select-all checkbox did (#444 ruling). The concept has neither.
+
+- The bar reads "N selected", Add tags, Set category, Clear: the Images bar's order.
+- Select all of the loaded shelf: Ctrl/Cmd+A in the grid (Images' key check; the search
+  box keeps its text meaning) selects every loaded prompt, windowed-out cards included,
+  and Escape in the grid clears it with focus kept on the card. "Select all N loaded"
+  follows the count while some loaded prompts are unchecked and at most 1,000 are loaded;
+  it selects them all and focus moves to Add tags; N follows each loaded batch. It sits
+  where D135's "Select all N matching" sits, but that offer appears once every loaded
+  image is checked; this one never reaches beyond the loaded prompts. No "all matching".
+- Add tags opens the shared `simpleInput` dialog ("Tag selected prompts", "Tags,
+  separated by commas", the tag vocabulary `GET /prompt_manager/tags` as suggestions, the
+  list the editor offers). The field refuses no tag, more than 20, a tag over 50
+  characters or with a control character, each with its sentence. Apply posts
+  `{prompt_ids, tags, expected_epoch}` to `POST /prompt_manager/bulk/tags`: prompt tags
+  only, never image tags, auto-tags or pair tags. Names are normalized as image tags are
+  (trim, no commas, casefold repeats folded); registry rows are found and inserted by
+  their exact name and only when some prompt gets them; a prompt gets only the names it
+  lacks by casefold. A prompt whose tags would pass 20 is skipped (`over_limit`), so the
+  editor can still save it. The answer is `{library_epoch, tags, updated, unchanged,
+  not_found, over_limit}`; the toast "Added “a, b” to N prompts." adds already-had,
+  skipped and not-found sentences. Storage restored: "Prompt storage was restored since
+  this page loaded. No tags were added."; unconfirmed: "Adding the tags could not be
+  confirmed. The Library was reloaded."; refused: "Tags could not be added. Try again."
+  The legacy `{prompt_ids, tags}` body is unchanged; both forms refuse a body that is not
+  a JSON object with 400.
+
+Tests: `tests/browser/workspace-library-selection.spec.mjs` (Add tags with its suggestions,
+field refusals and restore refusal; Ctrl/Cmd+A and Select all N loaded across batches and
+during a write); `tests/browser/library-concept.spec.mjs` (the bar comparison now includes
+Add tags); units `tests/js/workspace-library-selection.test.js`; Python
+`tests/test_bulk_library_tags.py`. A Python change: ComfyUI needs a restart.
+
+### No 1–5 prompt rating in the workspace (#447)
+
+**D153** (maintainer ruling 2026-10-28: the star is only for favorites; the concept keeps
+a 1–5 rating): the workspace shows and edits no prompt rating. The concept's rating
+appears in four places, and production draws none of them:
+
+- Library cards: the concept's footer reads "★★★★★ · Used today"; production reads only
+  the last use (amends D23). `library-concept.spec.mjs` takes the stars and their " · "
+  out of the concept page itself before measuring (`dropConceptRatings`), so the footer
+  facts are compared at production's width; it first checks that every concept card had
+  them.
+- Sort: the concept's "Highest rated" is not offered on Images or the Library (amends
+  D14); the comparisons drop it from the concept's options. A saved view or a Library
+  visit that still names `sort: "rating"` opens on Recently added; the server keeps such a
+  view as it was stored.
+- Editor (New prompt, Edit recipe metadata, Create text revision): no `#recipe-rating`
+  "Rating" select; `library-editor-canonical-comparison.mjs` `mapConcept` drops the
+  concept's Rating field. The editor never sends `rating`. An edit sends only changed
+  fields, so a stored rating stays as it is; a new prompt and a text revision create an
+  unrated positive (the revised prompt keeps its own rating; the legacy admin page shows
+  the revision as unrated). A reuse that leaves metadata unapplied compares title,
+  category, tags and notes only. The edit token still covers `rating`, so a rating
+  changed on a legacy page while the editor is open is an ordinary metadata conflict
+  whose review shows no visible difference.
+- System > Statistics: no "Avg. rating" column and no "Rated images" total (amends D96);
+  `system-concept.spec.mjs` maps the concept's table without that column.
+
+Data and API are unchanged: the `rating` column (`CHECK` 1–5), `PUT
+/prompt_manager/prompts/{id}/rating`, `rating` in Library, Images and statistics
+answers, and the server's `rating` sorts. The legacy pages keep their ratings until the
+cutover (#334). Favorites (the image star) are unchanged.
+
+Tests: units `tests/js/workspace-library-editor-state.test.js` (a prompt rated 4 edited
+and saved keeps 4, no `rating` in any body, no rating field),
+`workspace-library-state.test.js`, `workspace-images-state.test.js`,
+`workspace-saved-views.test.js`, `workspace-system-overview.test.js`,
+`workspace-library-format.test.js`; browser `workspace-library-editor.spec.mjs` (the
+fixture's positive stored with rating 4 still reads 4 after Edit, a revision, Add
+negative and a reuse), `workspace-library.spec.mjs`, `workspace-images.spec.mjs`,
+`workspace-saved-views.spec.mjs`, `workspace-system.spec.mjs` and the concept
+comparisons above.

+- **Waiting sets.** `_awaiting_foreign` and `_foreign_due` sit beside the keyless sets

+  `shutdown()` and `close()` clear them, and a closed handler re-checks nothing.
+- **Store.** One write through `survive_switch` (rerun after a Move library): a pair
+  through `ingest_resolved_pair(..., marks=RUN_MARKS)`, a positive through
+  `store_scanned_prompt_or_raise(..., RUN_MARKS)`. A created prompt carries category

[#216](https://github.com/ComfyAssets/ComfyUI_PromptManager/issues/216) adds the shared current-file inspector with exact generation facts, scoped provenance, raw/download evidence and loaded-collection viewer controls, including a slideshow that pauses at native video. This delivery does not establish whole-application parity, change the default entry point or constitute a release. Recorded chronological run/context browsing continues under [#209](https://github.com/ComfyAssets/ComfyUI_PromptManager/issues/209); image tagging/review, System consolidation and remaining organization capabilities continue under #196.

The legacy metadata page (`web/metadata.html`, served at `/prompt_manager/gallery.html`) stays reachable from Overview; its capabilities map to the shared inspector, including its one-click COPY ALL summary, which is the shared inspector's "Copy settings summary" (D117, LI-4). PR L3 ([#286](https://github.com/ComfyAssets/ComfyUI_PromptManager/pull/286)) shipped that button and local roles equal to the server's resolver (`web/js/workspace/local-resolver.mjs`, TESTING.md "Local roles (#249 PR L3, decision LI-1)").
