feat(audio-player): Resume Rewind select in the settings popover

The player window could only change Skip and Speed; resume rewind
lived exclusively on the profile page. The user-facing settings now
match Speed's precedent — changeable from the player, saved to the
account, applied immediately.

The select mirrors the default-speed row (CSP-safe @change bound to
one Alpine method; templ emits the option list from the shared
ResumeRewindOptions allow-list and the :selected expression against
the live resumeRewind field). Applying updates the running player's
value first — the next open/unpause uses it with no reload — then
PUTs audio_resume_rewind_seconds to the profile endpoint as the
string wire shape the server binds. normalizeResumeRewind gates the
select's value through 0/5/10 before both steps.

-## 💾 Network Storage (NAS / NFS / SMB)
-
-Libraries on network mounts are supported for everyday use — serving,
-reading, progress, and annotation sync all work over the mount — with a
-few behaviors worth knowing:
-
-- **Outage hysteresis.** When the mount drops, files miss one scan
-  (marked missing, hidden) then a second (archived, still recoverable).
-  When the mount returns — by path or by identical content elsewhere —
-  everything is restored automatically: annotations, progress, and
-  covers included.
-- **Retention purge.** Archived items older than `ARCHIVE_RETENTION_DAYS`
-  (default **90**, `0` = never auto-purge) are deleted for good by
-  library scans, annotations included. A NAS offline longer than the
-  retention window loses those books' metadata on return.
-- **Deleting while the storage is down is refused.** Deleting a book
-  cascades its annotations, so deletes are rejected with a clear error
-  while the item's library storage is unreachable. Archive the item
-  instead, or retry when the mount is back.
-- **Watch mode does not fire on network mounts** (inotify doesn't work
-  over NFS/SMB). The periodic scan is the change detector.
-- **Latency** — folder reachability checks are cached ~30s; large
-  libraries on slow mounts will still feel slower than local disk.

+## 2026-10-27 — Search-progress batch: viewer progress on cards
+- **`SearchJSON`**: `SearchMediaItemsUnifiedRow` + `viewer_percentage`
+  (float 0..1, NULL when the requester never opened the book). The
+  query LEFT JOINs `reading_progress` on the SAME `user_id` param the
+  library-visibility join already binds — one requester param, no new
+  wire inputs; the join is row-neutral (UNIQUE(media_item, user)).
+- **`BookInfo`** (CollectionsJSON / SeriesJSON / preview /
+  DashboardSections / search cards): + `viewer_percentage` (JSON null
+  when nil) and + `library_name` (empty on feeds that don't load it —
+  only the search-unified adapter populates both today). Adapters
+  other than BookCardsFromUnified keep emitting null/""; templ cards
+  render the progress bar/completed check only when populated.
+- The header-search dropdown now renders the templ `SearchResults`
+  partial (layout=dropdown on the same endpoint, HX-Request) instead
+  of the retired innerHTML renderer in web/src/search.ts — same
+  endpoint, same auth, content server-rendered.
+
+## 2026-10-29 — RLS visibility: item-scoped gates may answer 404 as well as 403
+
+With library visibility enforced by Postgres RLS (see
+database/schema/schema.sql), a hidden library's rows are INVISIBLE to
+the engine — item-scoped endpoints (chapters, tracks, download, detail)
+can no longer run their Go-level 403 gate because the row never arrives.
+Both answers are gated: 403 (Go-level explicit-library checks remain on
+listing endpoints) and 404 (row-level invisibility — no existence leak).
+Pins asserting 403 on item-scoped content endpoints widen to accept
+{403, 404}. Listing/scoped endpoints keep the strict 403 contract.
+
+## 2026-10-29 — Podcast episode columns join media_items (additive widening)
+
+The podcast integration (plan podcast-integration.md tasks 1.1/1.10) adds
+fifteen nullable/no-null-default columns to `media_items` — they surface in
+raw sqlc rows ONLY (`library-scoped list emits raw sqlc rows`), never in the
+resolved unscoped map:
+
+`source` ('scan' default), `source_feed_id`, `episode_guid`, `feed_position`,
+`season_number`, `episode_number`, `enclosure_url`,
+`declared_duration_seconds`, `transcript_url`, `chapters_url`, `hosts`,
+`guests`, `download_state`, `download_error`, `download_attempts`.
+
+Scan-sourced rows carry the inert defaults ('scan' / NULLs / 'pending');
+raw-row consumers that filter `source='scan'` (scanner paths) are unaffected.
+Nothing removed, nothing renamed.
+
+## 2026-10-30 — download_queue_pos joins media_items (additive widening)
+
+§0 item 4 of podcast-integration.md: the download pool's monotonic
+queue ticket. `download_queue_pos BIGINT` (NULL for scan rows and
+never-queued episodes) is stamped from the `podcast_queue_seq` SEQUENCE
+at enqueue time so claim order = enqueue order (the effective listening
+order). Raw-row pins (TestContractPin_MediaListBothBranches →
+rawRowKeys) whitelist the key. Nothing removed, nothing renamed.
+
+## 2026-10-30 — episode collections (additive widening, plan item 2/2.3/2.4)
+
+Two shapes widen, both ADDITIVE — nothing removed, nothing renamed:
+
+- **Collections envelope** (`GET /api/collections/:id` → envelopeKeys)
+  gains `rule_match_mode` (smart-collection match semantics, 'any'
+  legacy default | 'all'). Static collections emit the default value.
+- **BookInfo** (every card surface → bookInfoKeys) gains four STABLE
+  keys — `is_episode`, `feed_title`, `download_state`, `hidden` — the
+  episode-collections extras. Adapters that predate episode awareness
+  emit their zero values (`false`/`""`), matching the
+  viewer_percentage precedent (nil-representable, key always present).
+
+## 2026-10-30 — collections envelope gains filter_tree (additive widening, item 3.2)
+
+`GET /api/collections/:id` adds `filter_tree` to the envelope: the
+unified filter tree when the smart collection carries one (item 3.2 —
+tree-driven membership), `null` for legacy/static collections. The
+tree is the same qf DSL as saved filters (`{scope?, mode, children}`).
+Nothing removed, nothing renamed.
+
+## 2026-10-30 — rules endpoints RETIRED (filter-system unification, item 3.4)
+
+The per-rule CRUD endpoints and the preview endpoint are DELETED — the
+unified filter tree (item 3.2) is the only smart-membership authoring
+surface, and the rules PAGE is now the filter builder in the
+collection's scope:
+
+- `POST /api/collections/:id/rules`, `PUT/DELETE
+  /api/collections/:id/rules/:ruleId` — gone (legacy rule arrays still
+  EVALUATE until the collection is rewritten; conversions run at the
+  builder's first Apply via RulesToFilterTree).
+- `POST /api/collections/test-rules` — gone (the builder's live count
+  via /api/media-items/filter-count replaces the preview).
+- `POST /api/collections/preview` STAYS (the dashboard
+  custom-section-builder still consumes it — flagged for its own
+  migration, not silently broken).
+- Legacy compatibility KEPT: `auto_assign_rules` still round-trips in
+  the collections envelope; `PUT /api/collections/:id/match-mode`
+  still serves rules-array collections.
+
+Test-side deletions follow the asymmetry rule: subtests exercising the
+deleted endpoints are gone; their surviving SEMANTICS are pinned in
+their tree form (TestSmartCollections rewritten on trees,
+TestEpisodeCollectionsFilterTree, TestPodcastSmartCollections).
+
+## 2026-10-31 — collections RLS: cross-user detail/writes tighten to 404/no-op
+
+`collections` and `collection_items` joined the RLS-governed tables
+(policies `p_collections_*` / `p_collection_items_*`, predicates
+`app_can_read_collection` / `app_can_write_collection` — the same
+doctrine as the media_items family lens, 2026-10-29). Contract
+changes:
+
+- `GET /api/collections/:id` for another user's collection: was 200
+  (by-id readability), now 404 (row invisible).
+- `PUT /api/collections/:id` cross-user: was ungated success (no
+  app-level ownership check), now 404 — the RLS update touches no
+  rows, and the handler maps ErrNoRows to 404.
+- `POST /api/collections/:id/books` cross-user: was ungated, now 404
+  (rejectSmartMutation's GetCollectionData is RLS-invisible).
+- `DELETE /api/collections/:id` cross-user: still 204, but now a true
+  DB-level no-op (zero rows deleted) instead of an app-level free hit.
+- `PUT /api/collections/:id/view-settings` cross-user: 404 (the owner
+  gate stays as defense-in-depth; the DB is enforcement of record).
+- `PUT .../match-mode` and `.../items/order` keep their app-level 403
+  gates; the DB now backs them.
+- Reads: owner or admin (policy escape); non-owner non-admin users see
+  nothing, anonymous included. Future sharing rides the predicate
+  functions — one EXISTS branch in app_can_read/write_collection, no
+  policy migration.
+
+Test-side: TestCollectionsRLS pins the cross-user matrix end-to-end;
+fixture writes to non-system collections run as the row's OWNER
+(scopeExecAs/ownerSeedCtx) because the admin write-escape covers
+system collections only.
+
+## 2026-10-31 — legacy collection rules surface RETIRED (tree-only storage)
+
+The pre-tree rules machinery is gone — no production row ever carried a
+rules array or a non-default match mode (verified in the dev DB), the
+web never reads the envelope keys, and the Android app consumes none of
+it. Deletions:
+
+- `PUT /api/collections/:id/match-mode` — endpoint retired (it had no
+  doc page). The tree's root `mode` owns any|all semantics now.
+- Envelope: `auto_assign_rules` and `rule_match_mode` are REMOVED from
+  the create/list/detail/update payloads. This entry retracts the
+  2026-10-30 pins that listed them. `collection_type` and `is_smart`
+  stay.
+- Request: `auto_assign_rules`/`rule_match_mode` are no longer accepted
+  on create/update. A create carrying `auto_assign_rules` answers 400
+  naming the retirement — the custom-section builder's legacy save
+  (already failing to bind, verified live) fails loudly instead of
+  silently creating a hollow static section.
+- Storage: the `collections.auto_assign_rules` and
+  `collections.rule_match_mode` columns are DROPPED (idempotent
+  `DROP COLUMN IF EXISTS` in schema.sql).
+- Service: the rules CRUD layer (AddRule/SetRuleEnabled/RemoveRule +
+  validateRule + the UpdateCollectionRulesJSON query),
+  ParseRules/EnabledRules/IsSmartCollection, RulesToFilterTree (+ the
+  SSR preload branch), and the legacy branch of EvaluateSmartMembership
+  are deleted. IsCollectionSmart = tree presence.
+
+KEPT (live consumers): `POST /api/collections/preview` still accepts
+`rules` and evaluates them in memory (the custom-section builder's
+preview button); `include_auto` on the list stays (the Android app
+sends it). The builder's SAVE remains the flagged §12 tree migration.
+
+## 2026-10-31 — custom-section builder save: the flagged tree migration lands
+
+Supersedes the same-day retirement entry's loud-400 stance for the
+builder's payload. `POST /api/collections` now ACCEPTS the builder's
+shape and adapts it at write time:
+
+- `auto_assign_rules` (JSON-encoded array — string or bare) converts to
+  a filter tree via the restored `RulesToFilterTree`; converted trees
+  validate under `ParseFilterTree`, so an unhonorable rule is a 400 at
+  write naming the problem.
+- `match_type` seeds the tree's root mode (`any` default).
+- `manual_book_ids` attach to the created collection after create
+  (unparsable ids skipped — the AddBooks leniency).
+- `show_on_dashboard` persists (new create field).
+- `library_id` remains selection context only (not stored).
+
+Dashboard sections: smart user sections evaluate their tree LIVE —
+`GetUserCollectionItems` merges stored membership with the composed
+engine's matches (deduped, library-scoped, capped at the section
+limit). This exposed and fixed a real wiring bug: every production
+`NewDashboardService` call omitted the search service, so tree
+evaluation through the dashboard could never work (the test harness
+wired it correctly — the gap was production-only). The dashboard
+handler and both inline sites now receive it, and evaluation failures
+log instead of silently emptying a section.
+
+## 2026-11-01 — feed operator vocabulary collapsed (Option A): one name per semantic
+
+The feed field's menu offered `is`/`isn't` alongside `in`/`isn't in` —
+exact synonyms (the clause compiles both pairs to the same `ANY`). The
+MENUS now offer `in`/`isn't in` (+ has/missing) only. This is an
+offered-vocabulary narrowing, not a parse change:
+
+- Stored trees and saved filters carrying `feed is X` / `feed is_not X`
+  PARSE AND EVALUATE FOREVER (`legacyFieldOps` accepts the synonyms at
+  validation — the stored wire is never invalidated).
+- The fields payload (the client's operator menus) no longer carries
+  the duplicates.
+- Client id-cells are uniform: every operator on an id-valued field
+  accepts a set, so all id cells say "pick one or more" and accumulate
+  picks — no per-operator placeholder/pick distinction to explain.
+
+## 2026-11-01 — id labels resolve at render (SSR embed): refresh keeps names
+
+Pages that render a filter tree embed the tree's id→name map at render
+time (`data-id-labels` on the builder mount) — the collection editor
+(stored tree) and the bookshelf (URL `qf`). Before this, refresh showed
+raw uuids: only ids persist in trees; the client's id→label cache dies
+with the page, and the quiet suggest fetch reused the MEDIA-CONSTRAINED
+facet, so an id whose media doesn't match the tree's sibling rules got
+no row and no label (live repro: `feed in [A,B,C] AND title contains
+Chapter` labeled one feed of three — two feeds had no "Chapter"
+episodes).
+
+- `SearchService.FilterTreeLabels` reads the ENTITY tables (no media
+  join, no tree constraint): podcast_feeds and collections are
+  RLS-governed through the scoped handle (invisible ids resolve to
+  nothing); libraries mirror the facet's visibility join; added_by is a
+  plain username lookup. A zero-episode feed resolves its title —
+  pinned (TestRulesPageEmbedsIdLabels), as is the hidden-library
+  non-resolution.
+- The bookshelf drawer also HYDRATES at component init now (no
+  data-tree mount → read the form): the parent's x-init
+  (initBookshelf) runs BEFORE the nested builder component exists
+  (Alpine initializes parents first), so its builderData() call was
+  null and a URL-qf refresh left the drawer with an empty seeded rule
+  while the grid stayed filtered. Init-order contract pinned in
+  filter_builder.test.ts.
+- The quiet suggest fetch remains only as a fallback for trees the SSR
+  never saw (client-side apply flows); embedded labels make it a no-op
+  on refresh.
+
+## 2026-11-01 — unset podcast order defaults to reversed (audiobook-first)
+
+The per-feed listening order (the D5 `podcast_order:<feedID>` KV shown
+in the Order dropdown) resolved its UNSET state to "native" — feed
+document order, which runs newest-first for classic RSS, so an
+audiobook feed played its LAST chapter first. The unset default is now
+`reverse` at every resolution site of that one setting: the podcast
+page list + dropdown (`podcastOrderForFeed`), the player's feed chain
+(reader.go), and the download worker (`orderOverrideFor`).
+
+- Stored overrides are untouched: anyone who picked an order keeps it
+  (native remains a valid, savable choice).
+- No ordering semantics changed — `OrderEpisodes` and the four-option
+  vocabulary are as they were; only the unset fallback flipped.
+- Pinned: the player sequence config carries `"order":"reverse"` and
+  feed position 1 plays LAST for an unset feed; the podcast page's
+  dropdown renders `reverse` selected (TestPodcastPlayerOrderControl,
+  replacing the former native pin).
+
+## 2026-11-01 — new podcast smart collections are BORN reversed
+
+`POST /api/collections` with an EPISODES-scope `filter_tree` seeds
+`view_settings.chain_order = "reverse"` on the new row (merge semantics:
+an explicit client `chain_order` is never clobbered). The dropdown's
+default selection and the chain/page behavior come from the STORED
+value — no resolution-logic changes; books-scope smart collections and
+statics get nothing seeded; existing collections are untouched.
+
+Pinned (TestSmartCollectionBornReversed): episodes seed, explicit-keep,
+books-scope no-seed, static no-seed; TestEpisodeCollectionsFilterTree's
+born-reversed chain/page pins replace the former native expectations
+(which changelog here per the expectation-change rule). One misplaced
+pin from 81e54f89 was corrected while flipping: the API envelope's
+match list is NOT chain-ordered and never was — order pins live on the
+SSR page and the reader chain.
+
+## 2026-11-01 — label endpoint replaces the suggest-facet fallback
+
+`GET /api/filter/labels?field=X&ids=a,b,c` names id-kind filter values
+from their source tables (entity rows only — no media join, no tree
+constraint; visibility/RLS ride the request identity). Non-id fields
+are a 400; ids truncate at the same 100 cap the SSR embed uses.
+
+The client's label resolution (`resolveIdLabels`/`resolveLabelsAsync`)
+now uses ONLY this endpoint. The former fallback — the quiet suggest
+fetch through the MEDIA-CONSTRAINED facet — is deleted: it labeled only
+the ids whose media matched the tree's sibling rules (the live feed
+repro), which mattered exactly where the SSR embed can't reach:
+applying a SAVED filter from a cold bookshelf. The apply flow now
+resolves through the endpoint and rebuilds the chips bar when labels
+land. Pinned (TestFilterLabelsEndpoint): a zero-episode feed resolves
+its title, comma-joined ids resolve together, an unsubscribed feed id
+stays unnamed (RLS), non-id fields are 400.
+
+## 2026-11-01 — the rules-Apply path seeds the reversed default too
+
+PUT /api/collections/:id carrying an EPISODES-scope filter_tree seeds
+`chain_order = "reverse"` when neither the request nor the stored
+view_settings names one — the creation seed's twin: a static collection
+becoming smart lands with the same default a born-smart one gets.
+Explicit values (client-sent or stored — e.g. a deliberate native)
+are never clobbered. Pinned (TestSmartCollectionBornReversed):
+apply-seeds-when-unordered, respects stored native, respects client
+native.
+
+TestPodcastSmartCollections' acceptance pin updated with the same flip:
+the briefing acceptance now starts from the page's FIRST card (feed
+position 5 — the born-reversed default's book order) and chains into
+feed position 1. The acceptance meaning is unchanged: play from what
+you see, chained back-to-back within the live briefing set.
+
+## 2026-11-01 — audio resume rewind setting
+
+- `GET /api/media-items/:id/chapters` gained one ADDITIVE response key:
+  `resume_rewind_seconds` (int, the requesting user's setting; 0 for
+  anonymous). Existing keys unchanged. The web player and the Android
+  app both gate the value through the 0/5/10 allow-list, so servers
+  without the key (absent → 0) degrade to exact resume.
+- `GET /api/auth/profile` now always carries
+  `audio_resume_rewind_seconds` (int, never omitted — 0 is a real
+  value, exact resume). `PUT /api/auth/profile` accepts the key as the
+  keep_screen_awake-style STRING ("0"/"5"/"10") so the profile form's
+  select can send an explicit Off; JSON clients that omit it leave the
+  column untouched, and anything outside {0,5,10} is 400.
+  Pinned (TestAudioResumeRewind): default 0, PUT "5" rides the
+  chapters payload, non-allow-listed rejections change nothing,
+  explicit "0" resets everywhere, omitted key leaves it untouched.

 A: Bookhoard has its own sorting logic and doesn't import Calibre sort fields. This allows for consistent sorting across all books.
 
+## Writing metadata back to files (admin)
+
+The book page's metadata editor has a **Write to file** action alongside
+Save. Save updates Bookhoard's database only; Write to file persists the
+currently saved values into the artifact on disk, then re-extracts so
+everything stays in sync:
+
+- **EPUB/KEPUB** — the OPF embedded in the book is rewritten in place
+  (cover, chapters and reading position are untouched). The file's
+  checksum changes, so device syncs (Kobo, KOReader) re-key the book on
+  their next sync.
+- **Single-file audio (MP3/FLAC/M4A/M4B)** — the container's own tags
+  are rewritten (audio streams copied untouched, chapters and cover art
+  preserved). Only fields the format can carry are written: title,
+  subtitle (MP3/FLAC), authors, narrators (composer tag — Audible's
+  convention), series, date and genre.
+- **CBZ** — a ComicInfo.xml is written inside the archive (injected or
+  replaced). CBR/CB7 archives can't be rewritten in place, so they take
+  the sidecar path.
+- **Everything else** (PDF, folder books, CBR/CB7) — a Calibre-style
+  sidecar is written next to the file:
+  `metadata.opf` when the book is alone in its folder (Calibre's own
+  convention, so Calibre reads it too), or `<filename>.opf` when several
+  books share a folder, so one book's sidecar can never leak onto its
+  neighbours.
+
+The write mirrors exactly what the scanner reads back, and the original
+file is never touched if anything fails (temp file + atomic rename).

+# Filter cookbook
+
+Real questions, exact clicks. Every recipe uses the same builder described in
+[the guide](index.md) — same fields, same rules, wherever filters live.
+
+Recipes marked **collection** become smart collections that stay current forever; the rest are
+drawer filters you can save with a name.
+
+---
+
+## "New chapters of 7th Son, automatically" — collection
+
+1. **Collections** → open (or create) a collection → **Rules**.
+2. The scope is already *Episodes*. Add a rule: **Feed** → **in** → pick
+   *7th Son: Book One* (it becomes a chip — hit the × if you pick wrong).
+3. Add a second rule: **Title** → **contains** → `Chapter`.
+4. The header should read **MATCH ALL** (it does by default — every rule must match).
+5. **Apply to Collection**. Done: new chapters appear on their own, and the listening order
+   starts at **Feed order (reversed)** — chapter 1 first.
+
+---
+
+## "Lewis Carroll or George Orwell" — drawer
+
+1. **Filters** on the All Books page. Add: **Author** → **contains** → `Carroll`.
+2. Add a second rule: **Author** → **contains** → `Orwell`.
+3. Click the group header **MATCH ALL** once — it flips to **MATCH ANY** (or click the `AND`
+   chip between the two rules, same effect).
+4. **Apply Filters**. Either author is enough.
+
+*Flip it back to ALL and you'd get only books they both wrote — which is none, and the counter
+will tell you so before you apply.*
+
+---
+
+## "Long fantasy books I haven't started" — drawer
+
+1. **Genre** → **is** → `fantasy`.
+2. **Page count** → **at least** → `400`.
+3. **My reading** → **Reading status** → **is** → *Unfinished* (or your app's wording — the
+   status list is the fixed dropdown on that field).
+4. **MATCH ALL** stays on: all three must hold.
+5. Apply — then **Save** it as *"Big unread fantasy"* and it's in the Load menu forever.
+
+---
+
+## "Downloaded podcast episodes I haven't played" — collection
+
+1. A collection with an Episodes scope (see the first recipe — drop the Title rule if you want
+   whole feeds).
+2. **Downloaded** → **is true**.
+3. **Played** → **is false**.
+4. **MATCH ALL** on. **Apply to Collection**.
+
+---
+
+## "Added to my library this month" — drawer
+
+1. **Date added** → **within the last** → `30` (the days box — the field's page in
+   [Every filter field](fields.md) has its exact questions).
+2. Optionally **MATCH ALL** with **Library** → **in** → your audiobooks library.
+3. Save as *"New arrivals"*.
+
+---
+
+## "A dashboard shelf that builds itself" — dashboard
+
+1. Create a collection with the rules above (or open one).
+2. On the dashboard, add a section pointed at that collection.
+3. The shelf re-fills itself as your library changes — no maintenance.
+
+---
+
+## Sharing a filtered view
+
+Apply any filter, then copy the address bar. The filter rides in the URL — send it to another
+user of your server and they open the same narrowed view (they see it through their own
+libraries, not yours).

+This is the complete list of everything the filters can ask about, generated straight from the
+same source the app's menus render — it cannot drift from what you see in the UI.
+
+Filters come in two worlds:
+
+- **Books** — rules about books and your reading of them.
+- **Episodes** — rules about podcast episodes (feeds, downloaded, played).
+
+Every rule is **a field + a question + your values**. The "Ask" column is the question;
+the "Your values" column is what you provide. The **default** question is what a new rule
+starts with.

+
+| Place | What it's for |
+| --- | --- |
+| **The Filters drawer** (All Books / Podcasts pages) | A quick, temporary narrowing of what you see. Save it if you want to keep it. |
+| **Smart collections** (a collection's **Rules** page) | A filter that *lives* — the collection's contents update automatically forever. |
+| **Dashboard sections** | The same rules, feeding a shelf on your home screen. |
+
+One system, one set of skills, three payoffs.
+
+## Two worlds: Books and Episodes
+
+Rules about **books** (authors, series, your reading progress) and rules about **podcast episodes**
+(feeds, downloaded, played) are two different worlds. The field menus only show the fields that
+make sense where you are — you'll never see a podcast field on the All Books page. The complete
+list of every field is in [Every filter field](fields.md).
+
+## Anatomy of a rule
+
+Every rule is **a field + a question + your values**:
+
+> **Author** *contains* `asc`
+
+> **Feed** *in* `7th Son: Book One`
+
+> **Page count** *at least* `400`
+
+The field is *what* you're asking about. The question (contains, at least, is empty…) is *how*.
+Your values are *what counts as a match*. The complete questions per field are in
+[Every filter field](fields.md).
+
+## Picking values
+
+Two kinds of value boxes:
+
+- **Dropdown boxes** (Feed, Library, Collection, Added by): start typing and real names appear,
+  with live counts of how much matches. Click to pick — each pick becomes a **chip** with a little
+  **×** to remove it. Pick as many as you like; *any one of them* matching is enough.
+- **Typed boxes** (Author, Title, Page count…): just type. Several words means "contains these
+  words"; number boxes take numbers; date boxes take a number of days.
+
+The dropdown's counts are **live under your other rules**: if you've already narrowed to
+*Title contains Chapter*, the feed menu shows how many Chapter-titled episodes each of your feeds
+has. Rules already picked disappear from their own menu (removing a chip brings them back).
+
+## Groups: ALL and ANY
+
+When you have several rules, the group header — **MATCH ALL** or **MATCH ANY** — decides how they
+combine:
+
+- **MATCH ALL** — *every* rule must match. (The default, and what you want almost always.)
+- **MATCH ANY** — *at least one* rule matching is enough. This is how you ask for
+  "Lewis Carroll **or** George Orwell".
+
+**Click the header to switch it.** It says what it does, and clicking flips it.
+
+`+ group` adds a nested group with its own header (**GROUP ALL / GROUP ANY**), so bigger shapes
+build naturally:
+
+> Match ALL: Author *contains* `Carroll` **AND** GROUP ANY (Title contains `Alice` **OR** Title
+> contains `Wonderland`)
+
+For fine-tuning inside an ALL group, the small **AND / OR** chip between two rules mixes them —
+click `AND` and it becomes `OR`, joining those neighbors together. (The header switch and these
+chips are two different tools: the header sets the group's overall combine; a chip makes just two
+neighboring rules special.)
+
+## The live count
+
+While you build, the counter at the bottom — *N books match* — runs your rules against the real
+library. It's the exact number you'll get when you apply.
+
+## Defaults worth knowing
+
+- **Podcast listening order**: podcast pages and new podcast collections start at
+  **Feed order (reversed)** — book order, chapter 1 first. Change it per feed or collection from
+  the order dropdown; your choice sticks.
+- **Hidden libraries** (family lens) never match — a filter can't accidentally surface a library
+  that's hidden from you.
+- **Episodes that aren't downloaded** stay out of playback chains (they still appear in lists).
+
+## Keeping a filter
+
+- **Save** (drawer): name it; it appears in the **Load** menu from then on.
+- **Apply to Collection** (rules page): the filter becomes the smart collection — live forever.
+- Filtered views are **shareable**: the URL carries the filter, so a bookmark or sent link opens
+  the same view.
