+## Background threads at exit
+
+PromptManager's own background threads stop through one package teardown,
+`_stop_background_work()` in `__init__.py` (#301, #302). It runs once and
+works against one 10 s deadline. Each step gets the smaller of its own bound
+and the time left. The steps, in order:
+
+1. Refuse new previews (`refuse_auto_thumbnails()`), then detach the
+   monitor's callbacks (Needs review recorder, preview queue, Images listing
+   listener).
+2. `ImageMonitor.stop_monitoring` works against one 5 s deadline. Closing the
+   image handler joins the image worker; watchdog's `observer.stop()` (not
+   bounded here) and the observer join get what is left, which can be 0 s.
+3. `close_auto_thumbnails(final=True)` stops the preview worker (30 s) and
+   kills ffmpeg.
+4. `PromptTracker.shutdown` stops the prompt cleanup thread (2 s).
+
+A failing step, or a second Ctrl+C, is logged with its traceback and does not
+skip the later steps. A clean run logs one INFO line to PromptManager's log:
+`Background work stopped in 0.4 s: monitor=ok thumbnails=ok tracker=ok`. If
+any part is still running, one WARNING goes to the console:
+`Background work not stopped in time (10.0 s): monitor`. A Ctrl+C that lands
+between two steps (each step catches its own) is re-raised after the result is
+stored, with the parts not reached False, and the `atexit` callback is
+removed: the later steps are skipped, no summary line is logged, and a later
+call returns that result and runs nothing.
+
+ComfyUI never runs aiohttp's `on_cleanup` hooks, because it never calls
+`runner.cleanup()`. So `atexit` is the live host's path. It runs on Ctrl+C
+(`main.py` catches `KeyboardInterrupt` and returns) and on a normal exit.
+The teardown is registered after the execution history hook, so at exit
+(newest first) it runs before the history writer's 2 s dispose.
+It also runs from `on_cleanup` on hosts that do run it (our test servers) and
+from the tests' package unload (`cleanup_package`), and it removes its own
+`atexit` callback. Nothing runs when the process is killed: SIGTERM, a
+ComfyUI-Manager restart through `os.execv`, a closed Windows console, or
+ComfyUI Desktop stopping its server. SQLite's WAL journal covers those.
+
+Stop contract: `PromptTracker.shutdown(timeout)`,
+`ImageGenerationHandler.shutdown(timeout)` (restartable),
+`ImageGenerationHandler.close(timeout)` (final: `schedule()` refuses and a
+sealed run's re-check is dropped) and `ImageMonitor.stop_monitoring(timeout)`
+each signal their thread and join it within the bound. They return True only
+when it ended, and log a warning naming the part when it did not. Called on
+their own thread, they only signal.
+
+Test rules:
+
+- Every test that constructs a real `PromptTracker`, `ImageGenerationHandler`
+  or `ImageMonitor` ends with its final stop and an assertion
+  (`tests/background_stops.py`: `close_handler`, `stop_monitor`,
+  `stop_tracker`). The stop comes before the folder and databases are removed.
+  `tearDown` runs before `addCleanup` callbacks, so a class whose `tearDown`
+  removes files stops the thread there.
+- A test waits for a state through an `Event` set by the code under test, or
+  by a wrapper around it, with a 30 s ceiling. It never sleeps or polls for
+  that state.
+- A test that asserts "still running" first waits for an `entered` event
+  inside the held call, then stops with `timeout=0.05`.
+- A test that asserts a history writer's `dispose()`/`close()` is True right
+  after queuing work drains first (`drain_writer`), or holds the write itself
+  (#370).
+- Patch the module attribute of the code under test (for example
+  `utils.prompt_tracker.time`, or the package's `_clock`), or patch with
+  `wraps=`. Never replace a `time` or `atexit` function for the whole
+  process.
+- `tests/test_package_exit.py` runs a child process that imports the
+  package, leaves the image worker alive and returns. Its `atexit` reporter
+  checks the teardown's result. This is the interpreter path ComfyUI takes
+  after Ctrl+C, on all three OS.

 the table cannot be loaded, graph inspection is `unresolved` ("Inspection node
 semantics are unavailable") and ingestion is unaffected, because it never imports the table.
+Unknown nodes pass through (#381, maintainer-approved 2026-10-27; no per-node
+inventory): an output whose class the table, its `facts`, `lineage` and the code's
+adapters never name is read through, not refused. A `text` input is its text (the
+legacy encoder rule, so RegexReplace or LoRAfromText show their input text), except
+that a string output of a node with a seed input (`seed`, `noise_seed`,
+`sampling_mode.seed`) and no linked `conditioning`/`positive`/`negative` input is
+generated at run time (a language model such as TextGenerate, a wildcard):
+`runtime-value` naming it. Else, at output slot 0 or 1 of a node with a `positive` or
+`negative` input, only `positive` (slot 1, `negative`) is followed, nothing when it
+is not linked; else a linked `conditioning` alone; else every linked input except
+the table's `pass_through.skip_inputs` (core type inputs: model, clip, vae, image,
+latent, ...), each traced with kind `any`. A followed input with no text adds
+nothing; limits and selector choices propagate; another failure (`runtime-value`,
+`composite`, `malformed`) blocks, unless a PromptManager node was reached: this
+repository's own nodes are authoritative, and then only their texts count. One
+distinct text resolves; several make the sampler `ambiguous` "Several prompts reach
+the sampler" with one candidate per distinct outcome, in input order (at most 32,
+else `work-limit`). A PromptManagerPair's execution record is what ran: while its
+inputs are checked against it, a walk through an unknown node that fails, diverges
+or passes text through is unverifiable and never overrides the record. No text
+at all is `unsupported-node` naming the outermost unknown node. An unlisted output
+of a listed class (a sampler, a loader, a lineage node) stays `unsupported-node`, so
+the walk never reads another stage's prompt. `INSPECTION_RESOLVER_VERSION` is 2 for
+this rule; ingestion keeps the default profile (`RESOLVER_VERSION` 1). The legacy
+parity gate (`tests/test_legacy_parity_gate.py`) records, per corpus (the
+generation-params vectors, the inspection parity fixtures, the local resolver golden
+and selection cases, the unknown-node shapes in `tests/unknown_node_graphs.py`),
+every graph whose inspection positive equals the legacy parser's; a graph may join
+that list (`python3 -m tests.test_legacy_parity_gate --write`), never leave it. A graph
+may read differently from legacy only when `LEGACY_WRONG` there states why (legacy's
+first-sampler pick on a branch the file name identifies).
+Saver anchoring (#381): an inspected file's name (`path.name` on the server, the chosen
+file's name locally) anchors an unanchored inspection on the one node whose
+`filename_prefix` (literal, or traced as a string) has a last path part that makes the
+file's stem `<prefix>_<digits>` with an optional trailing `_`. That node's linked inputs
+are walked like a detailer's image ancestry, through any image node, and the listed
+samplers found are the candidates. No match, several matches, a walk that fails or no
+sampler found means no anchor: nothing is guessed and the file stays "several possible
+prompts". Ingestion ignores file names. Shared-conditioning stages: in a sampler's
+latent walk, an earlier sampler reading the very same conditioning links (positive and
+negative, or a guider; compared by node ID text and slot) is the same prompt, not an
+unattributed stage, when it is a plain first stage: not a detailer, no prompt override
+set, and no listed sampler in its own latent ancestry (else it stays unattributed) (`tests/test_resolver_saver_anchor.py`, shapes in
+`tests/saver_anchor_graphs.py` from the maintainer's `gpu_unlock_bench`, dataset and
+ANIMA runs; browser parity through the `anchor-*` cases, which carry `__file_name`).

+### 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.

+load only after 60 s (`TRIGGER_RETRY_SECONDS`). `tests/run_suite.py` and `tests/browser/server.py` point
 `LORA_MANAGER_SETTINGS_DIR` at a disposable folder, so no test reads the developer's real
 LoraManager settings; tests that call `load_layout` inject their own folder too.
 
+**Linked-only gate and the layout cache (#362).** While the integration is on, the LoRA
+allow-list (`ImagesMixin._lora_image_dirs`) is the layout's `media_roots` plus the CivitAI
+download cache, and `_media_roots(outputs)` appends it after the output folders for Library
+previews, the Library prompt detail, the per-prompt images page, `serve_output_image` for a
+root past the outputs, `inspect_image` and `reveal_image`. Under such a root only a file the
+database records as a linked image is served, inspected or revealed (`_linked_only_error`,
+by its given and its real path); anything else answers 403. Library responses mark that
+media `linked_only`: no preview file, no favorite, no Tag button. The allow-list's layout
+comes from `py/lora_layout_cache.py` (`tests/test_lora_layout_cache.py`, which injects the
+clocks, `stat` and `ntpath` and never sleeps): one entry keyed by the stripped configured
+path, reused while the plugin settings file's and the settings file's `(st_mtime_ns,
+st_size)` (or "missing") are unchanged, the install and every media root still resolve to
+themselves (a folder swapped for a symlink reloads and the guard runs again), and the entry
+is under `MAX_AGE_SECONDS` (30 s, monotonic clock) old. A load is stored only when no
+watched file was modified within `RACY_SECONDS` (3 s) of the load (git's racy rule: a write
+during the load, LoraManager's in-place write, FAT/HFS+ coarse times), every watched file
+could be checked (any `stat` error but not-found, and an offline Windows share, is "cannot
+validate"), the settings were readable, and no `clear()` ran meanwhile (generation
+counter). Hits take no lock; concurrent misses each load. A finished import (System job or
+legacy scan, both through `replace_lora_imports`) clears it. The integration-off check runs
+before it, and the configured-path rule (a configured path that is not an install under
+`custom_nodes` adds no folders) on its result; a hit also needs the same home folder, which
+the guard compares against. `serve_image` builds the allow-list in the
+executor. The cache writes one INFO line, "LoraManager layout changed: <source> settings,
+<mode> storage, <n> media folders", when a stored layout differs from the last one logged.
+The review, Start, the legacy scan and the trigger cache read the layout fresh. Image route
+tests clear the per-process cache in `ImageRouteCoverageCase.setUp`; `write_settings` in
+`TestLoraManagerMediaServing` back-dates its file 10 s so the first load is stored.
+
 `tests/browser/workspace_integrations_fixture.py` (`/__test__/integrations/*`) makes a fake
 LoraManager install and LoRA folder under the server's temp root, holds or fails the
 import, saves a blocking pair and answers CivitAI downloads with a stub opener, so no
 test reaches the network.

+
+System › Diagnostics & logs (`web/js/workspace/system-diagnostics.mjs`, D109–D110)
+reads and deletes only through the routes below; the legacy admin Logs and Diagnostics
+modals use the same routes and keep working.
+
+- **Rule R** (`utils/logging_config.py`): a file may be deleted as a rotated copy only
+  when it is a direct entry of the log folder named `prompt_manager.log.<n>` (`<n>` a
+  decimal integer ≥ 1 with no leading zero, compared after `normcase`) and a regular
+  file that is not a link or junction (`lstat`). Every other entry is `active`, `link`
+  or `other` and is never deleted. `/logs/files` rows carry that `kind`; links are listed
+  with their own `lstat` size and are not counted or sized by `/logs/stats`. A download
+  is served only for a regular, non-link file of the folder (a link, a folder or a name
+  not listed is 404), read off the event loop.
+- **Reviewed cleanup**: `POST /maintenance/preview {operation: "rotated_logs", options:
+  {}}` lists every rotated copy (basenames, size and time) and writes nothing; `POST
+  /maintenance/apply {token}` starts the `maintenance` job "Rotated log copies"
+  (admission `read`, not cancellable). Under the manager's files lock and every file
+  handler's lock it re-scans; when any listed file is missing, no longer rotated or
+  differs in size, `mtime_ns` or a non-zero inode, it deletes nothing and fails
+  `plan-changed` ("The log files changed since the review; nothing was deleted. Review
+  again.", Activity offers Review again). Otherwise it deletes exactly the listed files;
+  each is a Changed row ("Deleted · <size>"), a file that cannot be removed an Errors
+  row. Two Prompt Manager processes sharing one log folder are not locked against each
+  other: each file's identity is checked just before its unlink.
+- **Clear all logs** (`POST /logs/truncate`, also the admin page's Clear) empties the
+  active log through its handler, deletes the rotated copies (Rule R) and clears the
+  buffer; other files and links are kept. Response keys are unchanged.
+- **Runtime settings** (`GET/POST /logs/config`): the level (DEBUG…CRITICAL) and console
+  logging apply until the server restarts; the retention values are shown read-only in
+  the workspace and the API keeps accepting them.
+- **Report** (`GET /system/diagnostics`): built on the server from an explicit list of
+  fields (version, Python, platform, Viewer.js version, the four legacy checks, database
+  info, source counts, log configuration and statistics, the session's health summary
+  and the non-path configuration with `has_civitai_api_key`). Every path is relative to
+  a ComfyUI anchor or reads "outside ComfyUI"; a backstop scrub replaces any absolute
+  path or the saved key and counts it in `redacted`, which the tests require to be 0. It
+  takes a registry lease (409 `busy` while an exclusive job such as a restore runs).
+- **Compressed downloads**: the gzip middleware drops a handler's declared
+  `Content-Length` before it compresses a body, so the response declares the compressed
+  length. A stale length made a browser wait for bytes that never came: the log download
+  of any file over 1 KB hung (`test_compressed_body_declares_its_own_length`).
+
+The browser server writes its logs into `<server root>/logs`
+(`tests/browser/workspace_diagnostics_fixture.py`), whose hooks seed records with fixed
+times, rotated copies, a link (POSIX) and a user's `.bak`, and roll the copies over; no
+test reads or deletes a real log folder.
+
+`tests/browser/system-diagnostics-concept.spec.mjs` compares the section and its log
+cleanup review with the concept (dark and light, 1600x1100 and 390x844, no page scroll;
+both selects show their whole option at 320 wide). The fixture's `{mode: "concept"}` seed
+reproduces the concept's Logs sample: only its four buffer lines, a 1.4 MB active log with
+three rotated copies and console logging off, so those values are compared as the concept
+prints them. `mapDiagnosticsConcept` applies only D109 and D110, and `mapCleanupConcept`
+D100 (the shared `mapPlanConcept`) with D109's rule for this plan (no backup box, "Not
+needed: no library record changes", "Listed files"). The mutation check asserts that the
+unmapped difference is exactly the deviated paths. The comparison found that the Database
+line read `database_info.size_bytes`, a key the report does not have, so it always said
+"0 bytes"; it reads `database_size_bytes`, the key `get_database_info()` returns.
+
+### Legacy System capability coverage
+
+Every System capability of the legacy admin and gallery pages has an owner (#249 System
+S12, #329). Status is `covered` (a native control replaces it), `kept in legacy` (it stays
+on the legacy page, which keeps working) or `approved removal` (a ruling retired it). Native
+control is `` `<section>` · <role> · "<accessible name>" ``, `<section>` a System hash id
+and `<role>` one of button, combobox, switch, slider, spinbutton, textbox, group, status or
+term, followed by ` · in "<row title>"` when several rows of the section share the name.
+Every `covered` row names one, except the rows in `CONTROL_EXEMPTIONS`
+(`tools/vendor/legacy-coverage.mjs`), each with its reason: today only "Gallery per-image
+auto-tag / review", which the Images selection bar owns, not a System section. A row that
+is not `covered` names none (`—`). Test is the exact title of a test that runs, then its
+file. Anchors are line numbers on `main` at this PR.
+

+ComfyUI"``, never a basename that could be a user name. As a backstop,
+``scrub`` replaces any string that still looks like an absolute path, holds
+the saved key or the home folder (with or without its root), and counts each
+replacement in ``redacted`` (0 for a correct builder).

+"""A per-process cache of LoraManager's layout for the image hot paths (#362).
+
+Every Library list, prompt detail, inspect, reveal and serve request needs the
+LoRA allow-list (``ImagesMixin._lora_image_dirs``). Building it means finding
+the LoraManager install, reading its plugin settings file and its settings
+file, and resolving every folder. ``LayoutCache`` keeps the last result and
+reuses it while all of these hold:
+
+- the key (the configured install path, stripped) and the home folder the
+  folder guard compares against are the same;
+- the entry is younger than ``MAX_AGE_SECONDS`` (monotonic clock);
+- the plugin settings file and the settings file have the same signature
+  (``st_mtime_ns``, ``st_size``, or ``MISSING``) as when it was stored;
+- the install and every stored media root still resolve to themselves (a
+  folder swapped for a symlink reloads, so the folder guard runs again).
+
+A result is stored only when no watched file is "racy" (modified within
+``RACY_SECONDS`` of the load, git's rule for racily clean index entries),
+every watched file could be checked, the settings file was readable, and no
+``clear()`` ran during the load. What each rule covers: signatures catch a
+settings change on the next request; the racy rule catches a write during the
+load, a half-written file and coarse timestamps; the maximum age bounds the
+inputs no signature sees (``extra_model_paths.yaml``, environment, temporary
+failures); ``clear()`` makes a finished import's new folders servable at once.
+
+Hits and loads take no lock: a slow ``os.stat`` on a network share holds up
+only its own request, and two threads that miss together both load (both
+loads only read). A short lock guards the compare-and-store and the logging
+state; no file I/O runs under it. Standard library only, so it is tested
+without ComfyUI or LoraManager.

+"""System › Diagnostics & logs test hooks for the browser tests (#249 System S12).
+
+The logger writes into ``<server root>/logs`` (``repoint_logs``, called by
+``create_app`` before any record is written), so no test reads or deletes a
+real log folder. Every route refuses a log folder outside the server root.
+
+- ``POST /__test__/logs/reset`` restores the default logging configuration,
+  empties the active log, removes every other entry of the log folder (a
+  link is removed, never followed) and clears the in-memory buffer. The
+  global ``/__test__/reset`` calls it too;
+- ``POST /__test__/logs/seed`` ``{records, filler, rotated, active, link,
+  other}`` writes buffer records with fixed times (``records``: the concept's
+  four lines, then one DEBUG, ERROR and CRITICAL record, older; ``filler``
+  more INFO records older still), ``active`` bytes into the active log,
+  rotated copies ``prompt_manager.log.<n>`` of the listed sizes (fixed
+  times), on POSIX a symlink ``prompt_manager.log.<n+1>`` to a file outside
+  the folder (``link``) and a user's ``prompt_manager.log.bak`` (``other``).
+  ``{mode: "concept"}`` reproduces the concept's Logs sample (app.js 695)
+  for the comparison: the buffer holds only its four lines, the active log
+  is 1.4 MB with three rotated copies ("prompt_manager.log · 1.4 MB · rotated
+  copies: 3") and console logging is off, as the concept's toggle;
+- ``POST /__test__/logs/rotate`` rolls the copies over as the handler does
+  (``.2`` → ``.3``, ``.1`` → ``.2``, a new ``.1``), so a reviewed plan no
+  longer matches;
+- ``GET /__test__/logs/state`` answers the folder's entries (name, size, link)
+  and the buffer's length.
