* test(browser): API restores stay unseen by the open page's Activity poll (#413)

Specs that restore through the API while a workspace page is open check
how the page handles a restore it did not see. The page's Activity store
reads the job list every 15 s; on a slow runner (CI run 40646112668, a
16 s restore) that read landed during the restore, the page followed the
job and, as designed (S9), showed the open page again when it finished,
closing the Create tag dialog the vocabulary spec was about to use.

unseenRestore holds the page's job-list reads until the restore has
answered, so they read it as already ended. Used by the vocabulary,
library editor and history specs.

* test(browser): arm the restore gate before the page loads and drain reads in flight (#413)

A job-list read the page sent before the restore could still be answered
while it ran. The gate now routes every job-list read from before the
first navigation and, before a restore, waits for the reads in flight to
be answered. The history and library editor conversions are pre-emptive:
same race, never seen failing.

+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.

+### Logs and diagnostics contract (#249 System S12)
+
+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. It deletes or
+  empties no more than its confirmation showed (#389):
+  - `/logs/files` rows carry `identity`, the string `"<size>:<mtime_ns>:<ino>"` (a
+    string: `mtime_ns` and many inodes are beyond a browser's exact integers). The
+    workspace sends `{"expected": [{name, identity}]}` with the active and rotated rows
+    its dialog was built from. Under the files lock and every handler lock each listed
+    rotated copy must still match (`_matches_review`) and the listed active log must be
+    the same inode, or nothing changes: 409 `logs-changed`. Only listed copies are
+    deleted; one that appeared after the confirmation is kept. A malformed list is 400.
+  - Without a body (the legacy admin page, whose confirm lists nothing; also the
+    workspace when the file list could not be read and the dialog said "deletes its
+    rotated copies") every rotated copy present at the locked rescan is deleted.
+  - Either way, before anything changes (best effort, not a cross-process lock: a
+    write before our own last write, or any while file logging is off here, is not
+    seen): a second writer of the active log (our
+    handler's flushed stream is behind the file's size, or its file is now a rotated
+    copy: another ComfyUI sharing the folder) is 409 `logs-foreign-writer`; an active
+    log with more than one name (`st_nlink > 1` by `lstat` or the handler's `fstat`,
+    NTFS included) is 409 `logs-hard-link`, never truncated (replacing it instead would
+    rename a file our handler holds open, which Windows refuses). Each copy is
+    `lstat`-checked again just before its unlink; one that changed stops the clear there
+    and keeps it, the copies after it and the active log, which is emptied last.
+  - The browser fixture grows the active log through the handler's own stream, since a
+    second handle appending to it is exactly what Clear refuses.
+- **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.
+
+`tests/vendor/legacy-coverage.test.mjs` fails on a row with any of these problems:
+- no owner, or a status outside the three;
+- a malformed Native control cell;
+- a covered row without a control (unless exempt), or a control on a row that is not
+  covered;
+- a test title its file does not declare: `test(` or `it(` (`.only` and `.slow` count),
+  or a `def test_` at function or method indentation;
+- a title whose test is only declared with `.skip`, `.fixme` or `.fail`.
+
+A title that appears only in a comment or a Python docstring does not count. CI running
+those tests green is what proves them. `every covered legacy System capability has its
+native control` (workspace-system.spec) opens each covered row's section and finds the
+control by role and accessible name, inside its row when the cell names one. The shared
+"Review plan" of the per-operation review row and the Sources "Refresh" of the monitoring
+list stay unscoped: any row's control proves them.

+### Legacy System UI removed by S13
+
+System S13 (#330) points the legacy pages' System buttons at native System (a link that
+opens `workspace#/system/<id>` in a new tab) and removes the legacy copy of a capability
+only when its row above is `covered`. One row per removed capability: Capability is the
+exact Capability cell of its coverage row, Page is `admin` or `gallery`, Removed ids and
+Removed methods list what went (`—` for none), and Native test copies that row's Test
+cell. An id that stays on a System link is not listed, only its handler.
+
+`tests/vendor/legacy-coverage.test.mjs` fails when a row cites a capability that is not
+`covered` or copies another test, when an id or method is listed twice for one page, or
+when a listed id is still on its page (`id="…"` in the markup or the script, a
+`getElementById`/`querySelector('#…')` lookup, an entry of a modal-id list) or a listed

+these exact bytes and its result was stored", or that the bytes were found to

+every mark cites one byte record (``ON DELETE CASCADE``). Validation reads

+"""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.

+"""Prove the scratch-seeded resets leave the state the old resets left (#384).
+
+Run by hand on Linux (the browser server's platform):
+
+    python -m tests.browser.reset_equivalence
+
+It starts the browser server three times: twice seeding on the live database
+as before #384 (``PM_TEST_SEED_ON_LIVE=1``) and once with the scratch seeder.
+Each server gets the same sequence: every reset kind of ``/__test__/reset``
+and ``/__test__/concept/reset``, with other fixtures' resets and API writes
+between them. After every reset it reads every table's rows (by rowid), the
+output and input file trees (size, SHA-256, mtime) and the response body.
+
+Values that differ between the two old runs are wall-clock values (created_at,
+an unpinned concept "now", file mtimes); they are masked. Everything else must
+be equal between the old runs and the new one. Exit status 0 means equal.

+
+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
