John O'Keefe a86bdac87e refactor(collections): retire the legacy rules surface — tree-only storage
The pre-tree rules machinery is deleted: no row ever carried a rules
array or a non-default match mode (verified in the dev DB), the web
never read the envelope keys, and the Android app consumes none of it.
Dead code gets no documentation.

Removed:
- PUT /api/collections/:id/match-mode — endpoint, route, and the
  UpdateCollectionMatchMode query. The tree's root mode owns any|all.
- auto_assign_rules / rule_match_mode from every envelope
  (create/list/detail/update), from the create/update request shapes,
  and from the schema: both columns DROPPED (schema.sql carries
  idempotent DROP COLUMN IF EXISTS heals for existing DBs; sqlc
  regenerated).
- The rules CRUD service layer (AddRule/SetRuleEnabled/RemoveRule +
  validateRule + UpdateCollectionRulesJSON), ParseRules /
  EnabledRules / IsSmartCollection, RulesToFilterTree (+ the SSR
  preload branch), the legacy branch of EvaluateSmartMembership, and
  SmartEvalOptions.MatchMode. IsCollectionSmart = tree presence;
  create-path isSmart = collection_type=smart OR a filter_tree.

Kept (live consumers): POST /api/collections/preview still evaluates
rules payloads in memory (the custom-section builder's preview), and
include_auto stays on the list (the Android app sends it).

The custom-section builder's SAVE was already broken — its
stringified auto_assign_rules payload failed request binding (probed
live: 400 invalid request). Create now rejects that payload loudly
with a 400 naming the retirement, instead of silently creating a
hollow static section; custom-section-builder.md carries the flag.
The builder's tree migration remains the flagged follow-up.

Test-side (asymmetry rule — deleted behavior, deleted tests):
TestPodcastSmartCollections rewritten onto trees (mode lives in the
tree root), match-mode subtests and tree_wins_over_legacy_rules
deleted, TestRulesToFilterTree deleted, contract-pin envelope keys
retracted per the contract_pins 2026-10-31 retirement entry. Mirrors
hand-synced: openapi.yaml, bruno create/update, docs/api/*.md,
docs/schema.go, api.d.ts. Full container suite green (155s).

Get Collection

Returns one collection with its books and, for smart collections, the computed Up Next entries.

Example request

GET /api/collections/550e8400-e29b-41d4-a716-446655440000

Example response

{
  "id": "550e8400-e29b-41d4-a716-446655440000",
  "user_id": "8f14e45f-ceea-467f-a429-0b21bfc0b1a2",
  "name": "To Read",
  "description": "Books I want to read soon",
  "color": "#00FF00",
  "icon": "📖",
  "view_settings": { "kobo": { "view_mode": "grid" } },
  "books": [],
  "book_count": 0,
  "is_smart": false,
  "up_next": [],
  "created_at": "2026-10-24 13:57:01.81234 +0000 UTC"
}

created_at uses Go's time.String() format, not RFC3339. books and up_next are book-card arrays; up_next items carry id, title, author, cover, format, progress.

Query parameters

Param Type Notes
library_id uuid optional; scopes items/counts to one library (invalid values are rejected with 400)

Response fields

Field Type Notes
id string (uuid)
user_id string (uuid) owner
name string
description string
color string
icon string
view_settings object
filter_tree object | null the unified filter tree (qf DSL); null = static
books array book cards in this collection
book_count number length of books
is_smart boolean
up_next array smart collections only: computed next-up entries
created_at string
