test_api_images and test_api_prompts installed a MagicMock folder_paths,
so whenever one of them was imported before test_api_autotag the later
patch("folder_paths.get_output_directory") in test_api_history_outputs
left a mock attribute behind and two test_diagnostics_config tests
failed. tests/host_stubs.py now installs one real-module stub, used by
test_api_images, test_api_prompts and test_api_autotag (and through
test_api_images by the annotation modules, whose copy is gone), so the
modules pass in either import order.
On macOS (case- and normalization-insensitive APFS) a crafted target such
as A.PNG or an NFD name opened the listed a.png or NFC file while
realpath kept the requested spelling, so the tags were stored under a
second locator the Images filter never shows. Capture and verify now
require each path part to be spelled as its directory lists it and deny
any other case or Unicode spelling as an alias (409 source-changed, like
a symlink alias). A missing file with no other spelling keeps its usual
outcome.
- A preview cancelled while its file opens closes the handle and only
then ends the pin, so a doomed capture is never unlinked while open.
- An observe cancelled while capturing or reading releases the capture
instead of leaving it until the idle expiry.
- The model gate takes an on_skipped callback that runs once when the
work never starts; Generate passes the capture's release_use, so an
executor refusal no longer leaks a pin against the capture budget.
- The preview answers a single byte range with 206 and Content-Range
(416 for an unsatisfiable or multi-range header), still streamed inside
the pin, so Safari and WebKit can play video captures.
- _coded maps tag-limit (400), metadata-conflict and vocabulary-conflict,
and falls back to 409 with a fixed sentence for any other code instead
of raising KeyError.
The workspace Images listing now admits a file under a Tags filter when
every requested tag is carried by its linked positive or its current image
tag set, and q also matches image tag names (case-folded substring). Image
tags count only while a byte record is verified at the file's present
(size, mtime_ns) (spec amendment S1): the tagged records are streamed
once, only listed files carrying a filter tag or q hit are stat'ed, and
their linked positives are read through the file_path index so tags,
category, rating and the positive count combine.
The rooted inspector envelope gains a validated image_tags facet
(current / none / unavailable) read at the inspection's own stable stat.
A failed image-tag read fails a Tags filter like a failed link read and
degrades a q search to no image tags; plain listings read none. Legacy
gallery and search responses are unchanged.
- py/model_gate.py: one process-wide, non-blocking gate for loading,
swapping, running, downloading and unloading a tagging model. Worker
calls run shielded; a release requested while one still runs takes
effect only when it exits (client disconnect keeps the gate).
- Legacy /autotag/single, /start, /download/{type} and /unload hold the
gate and answer 409 {code: "model-busy"} while another operation holds
it; their bodies are otherwise unchanged. /autotag/models gains
suggestion_limit.
- AutoTagService.generate_tag_suggestions: WD14 (name, probability) best
first, GGUF/HF (name, None) in output order, first `limit` distinct
case-insensitively; generate_tags keeps its return; the image file is
closed before inference returns.
- POST /prompt_manager/image-annotations/suggest runs one engine on the
pinned capture, with strict per-engine options, never downloads
(409 model-unavailable) and never writes.
- config.json autotag.defaults.suggestion_limit, integer 1..100, default
10, validated on load.
- Capture probe decides Generate from the image header alone, so prompt
metadata over the inspection budgets no longer blocks it.
POST /prompt_manager/image-annotations/observe captures the file named by
the listing identity {root_index, root_scope, path} (scope checked against
the current roots before any file access) and answers the saved tag set of
exactly those bytes, refreshing a matching record's verified fingerprint.
GET/DELETE .../capture/{token} serve the private copy (no-store, nosniff,
pinned with acquire/release_use while it streams) and release it.
PUT .../tags re-hashes the current file and writes only when it still
holds the captured bytes, under the storage epoch and tag revision
(file-changed, storage-changed, tag-conflict, tag-limit, replayed).
Bodies are capped at 64 KiB with unknown fields refused; envelopes never
carry server paths or locators. Restores invalidate every capture and the
host's cleanup removes the capture directory.
