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).
Beam backfilled 11 library docs (CRUD, folders, visibility, browse, stats,
media-items) and re-attached frontmatter to create_collection.md — which had
silently lost its pilot version in cc893f75: the negative-test
'git checkout --' restored the OLD file because the pilot was never staged,
and a frontmatter-less doc is invisible to the gate. Claude restored the full
corrected pilot content (priority higher-wins, time.String() note, 409).
Claude registry: 11 entries + one inverted catch — DELETE /:id/folders DOES
bind {folder_path} (handler reuses AddLibraryFolderRequest); registry first
draft said bodyless. GET /:id/visibility returns joined
GetUserVisibleLibrariesRow (type_name etc.), not bare Libraries.
Gate-driven merges fixed create/get library response shapes (sqlc row keys:
created_by_admin_id, library_type_id, updated_at; dropped invented type/
folders/is_visible). Fixed invented request fields (user_id in
set-visibility; library_type_id in update). make test 9/9.
BREAKING CHANGE: Documentation URLs have changed
New structure:
- user/ - End-user documentation (device setup, sync guides, frontend)
- developer/ - Developer documentation (API reference, protocols, specs)
- operations/ - Operations documentation (deployment, troubleshooting)
- contributing/ - Contribution guides
Changes:
- Created portal INDEX.md files for each audience section
- Moved device guides to user/devices/ (kobo-setup.md, koreader-setup.md)
- Moved API docs to developer/ (api-reference.md, collections-api.md)
- Moved sync guide to user/sync-guide.md
- Moved troubleshooting to operations/troubleshooting.md
- Moved all split API docs to developer/api/
- Renamed protocol files (kobo-protocol.md, koreader-protocol.md)
- Added placeholder user guides (frontend, user-areas, settings, admin)
- Updated all internal links to new paths
- Updated Go code (http_handler.go, navigation.go) for new paths
- Updated main INDEX.md for audience-based navigation
Benefits:
- Clear separation of user and developer documentation
- Scalable structure for future user guide expansion
- Better organization and discoverability
- Audience-specific landing pages
