Two operator-asked modal UX changes (Scribe plan #514):
1. **Post title click → artist-scoped posts feed**
- The bold post title in ProvenancePanel is now the primary click
target. Click navigates to /posts?post_id=N&artist_id=A; the
PostsView already filters on `artist_id`, so the user lands in
that creator's stream, not the global one.
- The redundant "View post" link is removed. "Show description"
stays as the only action link below the meta line.
- Title is styled as a button-link: accent color, hover underline,
focus ring for keyboard nav (family rule 24 — UI quality bar).
2. **Suggestion rows look like buttons**
- SuggestionItem becomes a chip-card: visible border, hover/focus
background, unified container for name + score + actions
(operator's "nothing visual to unify the buttons to their object"
complaint).
- Accept is an explicit tonal pill button labeled "Accept"
(operator's pick over whole-row-clickable). 3-dot menu retains
alias/dismiss, now `variant="outlined"` so it reads as a button.
- Score is a fixed-width monospace pill on the right.
- "+ new" badge upgraded to a pill chip with accent border so
it's visibly an annotation, not part of the tag name.
Four coupled operator-asked changes to the view modal (Scribe plan #509):
1. **Autofocus tag entry on modal open** — TagAutocomplete grabs focus
in onMounted/nextTick so the caret is in the input the moment the
modal renders. No click needed to start typing.
2. **General suggestions expanded by default** — SuggestionsPanel's
general-category group now mounts with `:default-open="true"`.
Operator can collapse if too noisy, but the v1 frame shows them.
3. **Lower general threshold default 0.95 → 0.50** — MLSettings.
suggestion_threshold_general default matches character. Alembic
0029 also bumps the existing singleton row's value if it's still
at the old 0.95. Operator can re-tune from Settings → ML.
4. **Retire `copyright` + `artist` as ML suggestion categories** —
neither feeds a Tag.kind (`artist` retired in FC-2d-vii-c, never
really existed as a copyright tag-kind). They were surfaced in the
suggestions pipeline + threshold settings UI but had no follow-
through. Drop from SURFACED_CATEGORIES, suggestions._threshold_for,
ml_admin GET/PATCH allowlist, MLSettings columns (alembic 0029
drops the two columns), frontend CATEGORY_ORDER + CATEGORY_LABELS,
SuggestionsPanel.peopleCats, AliasPickerDialog kind-check, and
MLThresholdSliders rows.
Out of scope (intentional): `tag_kind` Postgres enum still includes
`artist` for historic Tag row queryability (per the model comment);
no operator pain reported, no enum-shrink needed.
Tests:
- test_surfaced_categories asserts {character, general}, excludes
artist + copyright.
- test_threshold_for_artist_is_unsurfaced extended to cover copyright.
- test_get_and_patch_settings asserts new 0.50 default and the absent
artist + copyright keys in the GET payload.
