Phase 1 of the series/collections/metadata overhaul
(~/.opencode/plan/series-collections-metadata-overhaul.md).
Schema (in place, idempotent):
- media_items.series_number INTEGER -> DOUBLE PRECISION: real-world
ordinals are decimals (0.5, 1.5 novellas); INTEGER silently truncated
them (calibre 2.5 pinned as 2 in tests).
- + subtitle TEXT, explicit BOOLEAN (sidecar ingest; ABS explicit /
Audible isAdult).
- + authors/authors_search/publishers/publishers_search TEXT[] NOT NULL
(narrators A2a precedent). Arrays are write truth; author/publisher
varchars become trigger-regenerated display strings
(sync_author_publisher_display) so every varchar consumer (trgm
search, facets, API, OPDS/Kobo) keeps working unchanged.
- Row-level NULL normalization for the new arrays in
set_library_type_name (A2 lesson: Go nil -> explicit NULL -> 23502).
- Backfills ARRAY[author]/ARRAY[publisher] — deliberately no
comma-splitting ('Tolkien, J.R.R.' would corrupt; scanner kept only
authors[0] historically).
- collection_items.position INTEGER + (collection_id, position) index
for playlist ordering.
Go: sqlc regen; MediaMetadata/handler params gain Subtitle/Explicit/
Authors/Publishers (legacy singles still accepted, arrays win);
SeriesNumber int32 -> float64 end to end; metadata_overrides adapted
with legacy override keys ('author'/'publisher') preserved so existing
user overrides survive; bulk author edit writes the array.
Pins widened (docs/contract_pins.md): raw sqlc row key set + the six
new columns; changelog entry added.
Verified: unit suite green; integration sweep (bulk/smart collections/
scanner/stats/sync/queue/calibre/pins/audiobooks) green against the
shared dev DB after in-place migration. Pre-existing unrelated red:
TestOwnershipAndAdminTestSuite/TestAdminCreateUser timezone inheritance
fails identically at the pre-change commit (live shared state).
Type is DERIVED, not stored: a saved ruleset makes a collection SMART,
no rules = STATIC (stored collection_items links, unchanged behavior).
No schema change — collections.auto_assign_rules JSONB already carried
the config; user's decision 2026-10-14 (handoff: live-at-render, not
refresh-on-scan; create-time Static/Smart toggle; v1 NO hybrid).
- Rule gains an enabled flag (absent = enabled, legacy rules unaffected).
- Rule CRUD: POST/PUT(DELETE) /api/collections/:id/rules[/:ruleId] — the
survivor dead effort of the rules-builder UI finally has real
endpoints (rules were never editable after creation; nothing ever
re-evaluated them). First rule converts a user collection to smart;
removing the last reverts it to static. UpdateCollectionRulesJSON
edits ONLY the rules doc so rule CRUD cannot clobber metadata.
- Live evaluation: candidates from GetVisibleLiveMediaForRules —
visible-library set (family lens enforced at source) + archived IS
NULL AND missing_scan_count = 0 — any enabled rule matches, title
order. Zero refresh hooks by design: always current by construction.
- Membership mutations (add/remove/bulk-add) are 400 on smart — v1 no
hybrid; collection_items.excluded stays the reserved future hook.
- Rules builder page (/collections/:id/rules) first time ever routable;
templ whole-attribute interpolation ("{ expr }" inside a quoted attr
value is literal text, as theme-{ user.Theme } silently proved).
- UI: create modal Static/⚡Smart cards (smart create redirects into the
rules builder), ⚡ badge + real per-card counts on the grid (smart =
live matches, static = stored-link count), smart detail renders
matched books with no hand-pick actions + an Edit Rules button.
- API: GET /:id gains is_smart + live books; GET /: keeps the Android
app's default exclusion, include_auto=true surfaces smart rows with
live counts; TestRules previews against the SAME candidates the live
render uses (visible + live, was raw first-1000).
- FIXED pre-existing regression from 7ce7321: static collection detail
with NO library_id returned zero books — QueryType != '' caught user
rows ('filter' default) and routed them to dashboard sections that
never contain them; now only real system query types go there
(handlers + SSR). App-visible symptom: /api/collections/:id without
library_id came back books:[] for every static collection.
Tests: collections_smart_test.go (conversion, disabled rules, mutation
guards, revert-to-static, validation, system-collection prohibition,
include_auto semantics). Full offline integration suite PASS.
