+### Selecting many images (#392)
+
+**D135** (beyond the concept, which draws only the per-card checkbox): Images selects
+like a file manager, in Grid, List (where the concept hides the checkbox) and Masonry,
+over every loaded batch. The selection is a set of image keys in display order, so
+ranges include cards that bounded rendering has unmounted.
+
+- Clicking a checkbox toggles it, and that image becomes the anchor. Ctrl/Cmd+click
+  anywhere on a card (image, star, Info, Tag) also toggles it and makes it the anchor;
+  nothing opens, inspects or changes the favorite.
+- Shift+click on a card selects the range from the anchor to it. Shift+click on a
+  checkbox gives its range the box's new state, so it can clear a range. The anchor
+  stays where it is. Without an anchor, the clicked image becomes the anchor.
+- In the grid, Ctrl/Cmd+A selects every loaded image; in the search box it keeps its
+  text meaning. Shift+Arrow, Shift+Home and Shift+End move focus as the plain keys do,
+  then select from the anchor (the starting card when there is none) to the new card.
+  Escape in the grid clears the selection. Escape in the bar clears it too, and focus
+  moves to the heading, as after Clear.
+- Touch: a 500 ms long-press (at most 10 px of movement) selects the card and turns on
+  touch selection mode. The context menu during the press and the click after it are
+  swallowed, and the card has no image callout. Taps then toggle cards until the
+  selection is empty. A keyboard Enter or Space keeps its plain meaning.
+- A plain click keeps its meaning: the image opens the viewer, and Info inspects.
+- When every loaded image is checked and the listing has more, the bar offers
+  **Select all N matching** right after the count. Pressing it gives **All N matching
+  selected**: later batches arrive checked, and unchecking any image goes back to the
+  loaded images minus that one. Clear, Escape, and a new search, filter, sort or rescan
+  end it. A refresh after a tag save keeps it. Return visits keep the loaded images,
+  and the offer shows again.
+- In that mode, Add tags and Auto-tag selected start the `image-tags` job with
+  `filter` (the listing's own query as an object: `q`, `subfolder`, `category`,
+  `tags`, `root`, `media`, `sort`, `favorites`, and with a Source the loaded root's
+  `root_scope`) instead of `targets`. The server resolves the filter at start, in
+  listing order, using the listing's own admission code (`_admitted_entries`). That
+  means "all matching" when the action starts: an output written since then that
+  matches is included. A `root_scope` that no longer names its root (the sources were
+  renumbered) answers 409 `source-changed`. The limit is 10,000 images (`MAX_LISTING_SELECTION`).
+  Over the limit, the client toasts "Narrow the view to at most 10,000 images." and the
+  server answers 400 `too-many-images`. No match is 400 `no-images`. Auto-tag in this
+  mode does not offer Review each image, because the review walks images in the
+  browser. Set category posts `{images_filter, category}` to `/prompt_manager/bulk/category`.
+  The server sets the category on the distinct linked positives and answers
+  `prompt_count` and `skipped`. A listing whose `positive_count` is 0 toasts the
+  nothing-linked sentence and opens no dialog, and over 10,000 matches it toasts the
+  limit sentence. Export metadata reads every image in
+  the browser, so it is `aria-disabled` in this mode, and its `title` says why.

+"""Hang guards for waits on disk-bound work (tests only).
+
+A test that waits for a job or handoff whose work is file and SQLite I/O
+(a safety backup with fsync, a restore, hashing and unlinking files) waits
+on that state; the ceiling below only ends a real hang. Hosted Windows
+runners stall disk I/O for tens of seconds at a time: a restore took over
+10 s (merge queue, #382), and on PR #405 every test setup in a 50 s window
+took up to 9 s against 0.1-0.6 s around it while the test bodies stayed
+fast, so a one-file duplicate cleanup missed a 10 s bound (#409).
+
+The ceiling is per wait and stays under the suite's 120 s per-test hang
+watchdog. A test with several such waits in a row can reach the watchdog
+first; either way a real hang fails, the watchdog with every thread's stack.

+"""Work running at Ctrl+C stops at its next safe point (#376).
+
+ComfyUI catches Ctrl+C in ``main.py`` and returns without closing its event
+loop. Python then joins every executor thread (``concurrent.futures``'s
+``_python_exit``, a ``threading._register_atexit`` callback) before any
+``atexit`` callback runs, so a call still running on the default executor
+used to keep the process alive until it returned. The package registers its
+own ``threading._register_atexit`` hook, which runs before that join: it sets
+the exit signal that ``Job.cancelled`` and ``map_parallel`` read, and kills
+the encoder processes.
+
+The child-process test starts three long calls on the default executor (a
+registry job checking ``job.cancelled`` between files, a ``map_parallel``
+batch and an encoder process that ignores the exit, as ffmpeg does on
+Windows), returns from its main module and must exit far sooner than any of
+them would end.

+"""A thread or pool refused at interpreter shutdown is quiet (#375).
+
+When the interpreter exits, ``threading._shutdown`` first shuts every
+``ThreadPoolExecutor`` (``submit`` then raises "cannot schedule new futures
+after interpreter shutdown") and joins the non-daemon threads; only then do
+the ``atexit`` callbacks (the package teardown) run. Our daemon threads keep
+working meanwhile. ``Thread.start`` is refused ("can't create new thread at
+interpreter shutdown") only later, once the interpreter is finalizing; the
+unit tests cover that case, the child process the pool case. Such a refusal
+is logged once at DEBUG, with no traceback, and leaves nothing pending.
+
+``threading.Thread`` is replaced only in the module under test (a copy of
+the ``threading`` namespace), never process-wide. The child-process test runs
+the real exit: a daemon thread queues previews while the main thread returns.

+"""The scan and Needs review anchor a file on the saver that wrote it (#390).
+
+The workspace inspector (since #383) passes the file's name to the resolver,
+which anchors the file on the one saver whose ``filename_prefix`` names it
+(``_GraphResolver.saver_stages``). The scan and Needs review use the same
+rule. Maintainer ruling: a file never falls through both the link and the
+queue, so when only that anchor resolves a file the default profile and the
+parser floor do not link, it is queued with the anchor's pair as its one
+choice (never linked automatically). No match, several matches or an
+unfinished walk anchor nothing, so such a file is queued as before. Apply
+re-resolves with the file's name, so a choice the anchor contradicts is
+refused as stale evidence.
