test(api): pin the resume-rewind contract

TestAudioResumeRewind drives the whole surface against the shared dev
DB with the fresh per-test regular user (the live admin is never
touched; the fixture book lives in a test-named library that cascades
away): default 0, profile PUT "5" rides the chapters payload,
non-allow-listed values 400 without side effects, explicit "0"
resets everywhere, and an omitted JSON key leaves the column
untouched.

Changelog entry in docs/contract_pins.md (additive chapters key +
the profile field's string-shaped PUT, keep_screen_awake precedent)
and the get_profile.md example gains the preference keys.

Debug note for the next agent: the first runs here 401'd with
'Ghost session rejected' — NOT a harness or auth bug. The tests never
execute schema.sql; the shared dev DB gets its schema from the app
container's boot. The rebuilt tests image ran the new GetUser
(selecting audio_resume_rewind_seconds) against a DB whose schema
came from the old app image — every GetUser errored, and the
ghost-session guard turned that into 401s. Applying the schema.sql
ALTER to the dev DB (what the next app rebuild does anyway) turned
the suite green. Until make rebuild-app runs, the running app
container serves the old binary.

+# 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

+# Filters — the complete guide
+
+Filters answer one question: *of everything in my library, show me the ones that match.*
+
+You'll meet the same filter system in three places:
+
+| 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.
