Operator-flagged 2026-06-02 — the 0.50 default (set on 2026-06-01)
surfaces too many low-confidence picks in the modal's Suggestions
rail. 0.70 keeps the rail signal-rich while still showing more than
the original 0.95 (which hid almost everything).
Alembic 0033 updates the singleton row conditionally — only rows
still at the old 0.50 default flip to 0.70. Operators who tuned to
some other value via Settings → ML keep their pick.
Settings UI already exposes both sliders (MLThresholdSliders.vue),
so further tuning continues to work without a deploy.
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.
Base.metadata's convention applies ck_%(table_name)s_%(constraint_name)s.
ml_settings and tag_allowlist passed already-prefixed names
(ck_ml_settings_singleton / ck_tag_allowlist_confidence_range), so the
ORM-side names came out doubled (ck_ml_settings_ck_ml_settings_singleton
etc.) and the migration-0003 smoke tests failed.
Same class of bug fixed in FC-2a for ImportSettings — should have applied
that lesson here. Bare names ('singleton', 'confidence_range') let the
convention produce the final names that match migration 0003's literal
DDL. Migration unchanged; only the model __table_args__.
