Phase 0 of the reader redesign:
- Panels no longer render under the top/bottom bars: sidebars get
measured insets (same resize/safe-area mechanism as the viewport);
panel max-height now derives from the bounded sidebar instead of a
100vh guess; right-side border targets the actual sidebar.
- Bookmarks work end-to-end for the first time: REST CRUD under
/api/media-items/:id/bookmarks (create/delete route through
AnnotationService for dedup/LWW/tombstones), fix UpdateMediaBookmark
referencing nonexistent updated_at column, frontend posts to the
real API with per-format position (CFI vs page), live list with
jump + delete instead of SSR-only snapshot.
- Fix chapter matching in progress saves: boundaries were compared by
a nonexistent tocItem property, so chapter was never persisted.
- Remove dead UI: Navigator panel stub, empty dictionary popup shell,
unwired Chrome Behavior select; purge 160 stale build artifacts.
- Reader chrome now follows the user's app theme instead of hardcoded
theme-tokyo-night.
Content duplicates (same library + file_sha256 at different paths,
e.g. the same book imported twice under two names on a preexisting
database) cannot be auto-collapsed the way path duplicates were:
keeping both copies may be intentional. Surface them for an explicit
admin decision instead.
Schema:
- new hash_conflicts table keyed (library_id, file_sha256) with a
status/resolution lifecycle: 'pending' until an admin resolves via
'keep_all' or 'kept:<uuid>' (which copy was kept after merging)
- resolution is VARCHAR(50) - 'kept:<uuid>' is 41 chars; include a
widening ALTER for databases created with the initial 30-char width
- resolution/resolved_by/resolved_at record who decided what and when
Queries:
- ListMediaItemsMissingHash: items imported before hashing existed
(file_sha256 IS NULL), ordered oldest-first for the backfill pass
- FindHashConflictGroups: the content-duplicate group detection
(GROUP BY library_id, file_sha256 HAVING COUNT(*) > 1)
- ListMediaItemsBySHA256AndLibrary: full membership of one group
- CreateHashConflict: upsert with DO NOTHING so already-tracked groups
are untouched - critical behavior: a group an admin resolved as
'keep both' is never re-flagged by later sweeps
- ListPendingHashConflicts: admin listing with library name and live
item counts (items may have been deleted since flagging)
- GetHashConflict / ResolveHashConflict: lifecycle
- GetMediaItemUsageCounts: per-item progress/highlight/bookmark/note/
collection counts so the admin can make an informed keep choice
- ReparentMediaItemChildren: sqlc binding for the existing
reparent_media_item_children() migration function, used to merge a
losing copy's child rows into the kept copy
A read-then-write race in processMediaFile allowed the same file to be
imported twice: two concurrent scan jobs (startup scan, fsnotify dirty-
directory scan, periodic backup poll, or a manual scan each run on
separate worker goroutines with separate MediaScanner instances) could
both SELECT 'not found' and both INSERT. There was no transaction, no
row lock, no unique constraint on (library_id, file_path), and no
ON CONFLICT clause, so nothing stopped the double insert. Observed in
production as two identical 'Head First SQL' rows created in the same
second (same sha256, size, path, library).
Database enforcement:
- schema.sql: add UNIQUE(library_id, file_path) constraint, guarded so
re-runs don't error
- schema.sql: add self-healing migration that runs on every startup -
dedup_media_items_by_path() collapses existing path-duplicates and
reparent_media_item_children() moves all child rows (progress,
highlights, bookmarks, notes, collections, formats, aliases, kobo
entitlements, etc.) onto a survivor before deleting losers, so the
constraint applies cleanly on already-duplicated servers without
losing reading history. Survivor picks the row with the most user
data, ties broken by lowest id
- CreateMediaItem: upsert via ON CONFLICT (library_id, file_path) DO
UPDATE so concurrent inserts collapse to one row and return it
- CreateMediaItemFormat: upsert via ON CONFLICT (media_item_id,
format_type), closing the same race on format rows
Application-level guards:
- media_scanner processMediaFile: after computing the file hash, check
GetMediaItemBySHA256AndLibrary (new query) and treat the file as
existing when identical content is already in the library under a
different path (content dedup, library-scoped so multi-library
setups still work)
Ops tooling:
- scripts/dedup_media_items.sql: standalone idempotent maintenance
script with a dry-run report (path + content duplicate groups, child
row counts) and transactional cleanup, for servers that prefer to
dedup manually before upgrading
Verified against the live database: the duplicate pair was collapsed
(reading_progress preserved on the survivor), schema.sql re-runs are a
no-op, and the constraint is in place with 62 unique books remaining.
Add a typed, cached registry over the system_settings table so that
values which used to be hardcoded Go literals can be changed at runtime.
Schema (database/schema/schema.sql):
- Extend system_settings with setting_type, min_value, max_value,
requires_restart, and category columns (all ADD COLUMN IF NOT EXISTS,
nullable for backward compat with the original three rows).
- Seed rows for every tunable: session duration, password rules,
login lockout, auth/device rate limits, OPDS page size, tombstone TTL,
conversion cache TTL, sync queue interval/batch, and worker pool
size/cap. Seed values equal the previous hardcoded literals, so
behavior is unchanged on upgrade. ON CONFLICT DO NOTHING preserves
any admin-modified values.
Queries (queries.sql):
- Add UpsertSystemSetting (RETURNING *) so new keys without a seed row
can still be written through the API.
- Add GetSystemSettingFull + GetAllSystemSettingsFull returning the
full typed row.
- Refactor CleanupExpiredRefreshTokens to take the retention window as
a parameter (make_interval(secs => $1)) instead of the INTERVAL '7
days' literal, so it can follow a configurable session duration.
Registry (internal/database/settings_registry.go):
- SettingsRegistry holds an in-memory cache of all known settings,
populated by Load at startup and refreshed by Reload on writes.
- Typed domain getters (SessionDuration, PasswordRules, DeviceRateLimits,
TombstoneTTL, OpdsPageSize, ConversionCacheTTL, SyncQueueConfig,
WorkerPoolConfig, LoginLockout, AuthRateLimit, ...) with compiled-in
fallback defaults and min/max clamping, so a corrupt or missing row
can never break the app.
- SettingDefaults is the single source of truth for keys, types, bounds,
and human descriptions; All() exposes metadata + current values for
the admin UI/API.
The registry lives in the database package (rather than its own
internal/settings package) because a quirk in this custom go1.26.5
toolchain prevented the large handlers package from importing any
newly-created package; every consumer already imports database.
Tests: settings_registry_test.go covers default validity per type,
int clamping at both bounds, garbage-value fallback, and unknown-key
lookup.
Add migration columns to media_highlights, media_notes, and media_bookmarks
for cross-device annotation sync:
- dedup_key: SHA-1 of normalized selection text + bucketed position, used
as the stable cross-device identity for annotations
- last_modified_at / last_modified_source: edit clock for LWW resolution
and cross-source conflict detection
- deleted / deleted_at: sticky tombstone columns for delete-wins semantics
with a 30-day TTL before rows are physically purged
- note_text on highlights: stores attached notes from KOReader entries that
have both selected text and a user note
- Location columns on bookmarks (cfi_position, percentage_location,
epubcfi_location, chapter_reference, paragraph_reference)
- device_sync_data JSONB on all three tables: stores per-device native
identifiers (e.g. KOReader pos0/datetime, Kobo bookmark_id) so each
device can locate and manipulate its own copy of an annotation
Add partial unique indexes on (user_id, media_item_id, dedup_key) where
deleted = FALSE to enforce one active annotation per dedup key.
Add tombstone purge indexes on (deleted, deleted_at) for efficient GC.
New queries:
- GetByDedupKey for all three tables (returns active or most-recent tombstone)
- CreateFull / UpdateForSync for all three tables (populate sync columns)
- TombstoneByDedupKey / TombstoneByID for all three tables
- PurgeExpired* for all three tables (GC past TTL)
- GetActiveAnnotationsForBook (filtered union of highlights + notes)
- GetTombstonedAnnotationsForBook (union of all 3 deleted within TTL)
- GetMediaBookmarks with deleted filter
- GetMediaBookmark (singular) with deleted filter
- Added deleted=FALSE filter to GetMediaHighlights, GetAnnotationsForBook
- CreateAutoResolvedSyncConflict (INSERT with resolution_status='auto_resolved')
Stores surrounding text (~100 chars) at the reader's current position.
Used as fallback for CFI resolution when converting between epubcfi
and CREngine XPointer formats.
Updates:
- schema.sql: add context_text TEXT column, update stored procedure
- queries.sql: add context_text to GetUniversalProgress and
UpdateUniversalProgress queries
- Regenerate sqlc Go code (models.go, querier.go, queries.sql.go)
Regenerated database code after sqlc version upgrade from v1.30.0 to
v1.31.1. No functional changes — only the version header in generated
files was updated.
Files: db.go, models.go, querier.go, queries.sql.go
The created_at column stores file modification time (intentional for preserving
original metadata), but this makes 'Recently Added' sorting unreliable for
imported files. Add imported_at column that records the actual database insert
timestamp.
Changes:
- Add imported_at TIMESTAMPTZ column to media_items (nullable)
- Update GetRecentlyAddedItems to sort by imported_at DESC NULLS LAST first
- Add ReassignLibraries and ReassignMediaItems queries for admin deletion handover
- Add SyncLibraryTypeExtensions query for startup extension sync
- Update all media_items SELECT queries to include imported_at column
- Add timezone column (VARCHAR(50) DEFAULT 'UTC') to users table
- Add default_timezone row to system_settings seed data
- Add idx_users_timezone index for user timezone lookups
- Add UpdateUserTimezone and GetSystemTimezone queries
- Regenerate sqlc code (models, querier, queries.sql.go)
- Reuse existing UpdateSystemSetting for system timezone updates
instead of creating a redundant UpdateSystemTimezone query
- Add ProcessingIssues model struct
- Update Querier interface with processing issues methods
- Add generated query implementations for CreateProcessingIssue, ListProcessingIssuesByLibrary, GetProcessingIssueStats, ResolveProcessingIssue, DeleteProcessingIssue
- Add GetLibraryWithType query for fetching library with type information
- Add library_type_name VARCHAR(50) column to media_items table in schema.sql
- Create PostgreSQL trigger 'set_library_type_name_on_insert' that automatically
populates library_type_name by joining libraries table with library_types on insert
- Add library_type_name parameter to CreateMediaItem SQL query
- Update Go models (models.go) to include LibraryTypeName field
- Add UpdateMediaItemChapterMetadata query method to querier.go
- Regenerate queries.sql.go with sqlc
This allows media items to store their library type (e.g., 'Books', 'Comics', 'Manga')
at the database level, enabling filtering and display without needing additional joins.
Add database schema and SQL queries for generic saved filters system
that allows users to save custom filter presets for any resource type.
Database Schema:
- Add saved_filters table with user_id, name, resource_type, filters (JSONB)
- Create composite index on (user_id, resource_type) for efficient lookups
- Create index on (user_id, name) for future name search feature
- Add update_updated_at_column() trigger to auto-update timestamps
- Make trigger creation idempotent with DROP TRIGGER IF EXISTS
SQL Queries (5 new queries):
- GetSavedFilters: List all filters for user + resource type
- GetSavedFilterByID: Retrieve single filter by ID
- CreateSavedFilter: Create new saved filter
- UpdateSavedFilter: Update filter name/criteria
- DeleteSavedFilter: Remove saved filter
Design Decisions:
- Generic resource_type field supports any resource (media-items, collections, devices)
- JSONB filters field allows flexible schema without migrations
- User-scoped via JWT (user_id foreign key with CASCADE delete)
- Automatic updated_at timestamp via database trigger
Generated Code:
- database.SavedFilters model (10 fields including JSONB filters)
- All 5 CRUD query functions with proper parameter types
- pgtype.UUID wrappers for UUID parameters

Add support for Carousel-style dashboard with unified collections architecture:
Database Schema Changes:
- Add user_dashboard_preferences table:
- hidden_collections: TEXT[] for managing section visibility
- collection_order: TEXT[] for custom ordering
- items_per_section: INT for limiting items per section
- Update collections table:
- user_id: Make nullable to support system-owned collections (NULL = system)
- show_on_dashboard: BOOLEAN for controlling visibility
- query_type: TEXT for different query types (continue-reading, recently-added, etc.)
- priority: INT for display order (lower = higher priority)
- is_system_collection: BOOLEAN for flagging system defaults
- Update collection_items table:
- Add excluded BOOLEAN for user overrides of auto-assigned items
Indexes:
- idx_collections_dashboard: (user_id, show_on_dashboard, priority) WHERE show_on_dashboard = true
- idx_dashboard_prefs_user_library: (user_id, library_id)
- idx_collection_items_excluded: (collection_id, excluded) WHERE excluded = true
System Collections (pre-seeded defaults):
- continue-reading: Books with 0 < progress < 1
- recently-added: Newly added items to library
- recently-read: Books with progress >= 1
- not-started: Books with progress = 0 or no record
This implements Phase 1 of the Carousel-style dashboard redesign plan.
Auto-generated changes from running 'sqlc generate' after query updates:
- models.go: updated with SystemSettings struct, removed scan fields from Users
- querier.go: updated interface with new system settings methods

- Tests already use array format (no changes needed)
Benefits:
- GIN indexes enable faster array searches
- Normalization prevents data quality issues (case, duplicates)
- Array operations use PostgreSQL native operators (ANY, &&, unnest)
- Better separation of concerns (no string parsing in application)
Complete the rename by updating:
