* fix(tagging): Tag output images tags each image, not its prompt (#379, PR 1) The native "Tag output images" job now runs the image-tags loop over every still image the output folders list, linked or not: each image gets its own model tags (at most "Suggestions per image") in its image tag set, and its bytes are marked auto-tagged in a new media_image_autotags table. No prompt tag or prompt text is written. - database/autotag_schema.py: one forward-only WITHOUT ROWID table, optional in old backups, refused without the annotation group. - add_image_tags/replace_image_tags take mark_autotagged; autotag_state and autotagged_locators read the marks through the one current-record rule. - "Skip already tagged" skips images whose current bytes are marked, counted in a stat-only pre-pass; hand tags do not count. - The review counts images and estimates the time (WD14 on CPU or CUDA). - System > Auto-tagging review rows and copy, D134 and the Auto-tagging contract follow. Part of #379 * fix(tagging): end the batch job after its cleanup and report pre-pass progress (#379) The job read as ended while it still held the model gate, so a quick restart could be refused with model-busy. Pre-pass chunks now publish progress, and a cancel between chunks keeps exact counts. Part of #379 * fix(tagging): measured GPU rate, and an ended image-tags job shows no time left (#379) The live check measured WD14 on CUDA at 0.167 s per image (100 images in 16.7 s with the model load), so the review estimate uses 0.17 s. A finished or cancelled Auto-tag/Add tags job kept "Processing file N of N · about X min left"; it now ends with "<verb> <state> · N files processed". Part of #379 * test(browser): reload the admin page only after the in-place edit saved The gallery-to-admin workflow pressed Enter and reloaded as soon as the edited text showed; the page saves after showing it, so a reload that won the race abandoned the PUT (WebKit, run 40564511000). The test now waits for the save's answer. Part of #379 * test(tagging): the batch coverage row names the renamed #379 test

"""Per-image tag sets (#249): byte-exact storage in the shared vocabulary.
|
|
|
|
A tag set belongs to one byte record (``media_annotation_bytes``): the
|
|
whole-file SHA-256 of one physical file, owned by the file's private locator
|
|
(``media_annotation_files``). Callers pass verified facts (digest, size,
|
|
``mtime_ns``); nothing here reads the filesystem or resolves an owner through
|
|
prompt links, so tagging one image never changes another image, a prompt or a
|
|
pair.
|
|
|
|
Commands run in one ``_pair_transaction`` fenced by the storage epoch, like the
|
|
native Library and vocabulary commands. A save is a full replacement guarded
|
|
by the set's ``tag_revision``; the identical set sent again (a lost-response
|
|
retry, or the current set at its own revision) answers ``replayed: true`` and
|
|
writes nothing. ``add_image_tags`` unions into the existing set, keeping the
|
|
stored spelling. Names enter the global ``tags`` registry exactly as spelled,
|
|
so vocabulary rename, merge and delete carry image links with prompt and pair
|
|
links (``PromptDatabase._move_tag_links``).
|
|
|
|
Cheap reads (spec amendment S1) treat a byte record as *current* only while
|
|
the file's present ``(size, mtime_ns)`` equals the record's verified
|
|
fingerprint; a file without a current record shows no image tags.
|
|
|
|
A write made from a tagging model's result passes ``mark_autotagged`` (#379):
|
|
the byte record is then marked auto-tagged (``media_image_autotags``) in the
|
|
same transaction, so a mark never exists without the write it records. Hand
|
|
tags never mark.
