The design parked in the handoff (multi-tier stats off reading_history; bookorbit-style in data, not looks) is in. The real prerequisite work was data: reading_history existed but NOTHING wrote to it — the whole stats feature was sitting on an empty table. - CAPTURE (no client changes, no repo-boundary crossings): every successful progress write through SaveProgress (KOReader + app + web + Kobo + offline queue — the one chokepoint) now records one reading_history session row: span = the interval since the PREVIOUS write instant, pages = positive page delta when both sides know the page index, marker rows for first contact. Spans over 2h are kept as zero-second markers (overnight suspend→resume, offline flushes must not inflate totals) — the honest 'sync cadence, not a stopwatch' caveat stays. device_id only when a REAL device row matches (the web/app progress path historically stuffs the USER id into DeviceID — probe instead of trusting it; FK violation would silently drop every capture). Source preserved in device_metadata. - API: /api/stats/summary?range=7|30|90|year (totals, zero-filled daily arrays, streaks, most-active day/weekday, top books, library breakdown — one call), /api/stats/this-week (widget: rolling 7d vs previous + streak), /api/stats/books/:id (lifetime + recent sessions). All bucketed in the user's timezone; finished ≡ any push ≥0.995; visible-library lens enforced at source. Legacy /api/analytics/* kept untouched. Range windows anchor end-of-day to the START of today (blasting the clock time into tomorrow resolved 'today' a calendar day late — found by the streak test). - /stats page (sidebar Stats between Progress and Devices, previously /analytics was an orphan): range selector, five stat cards, two Chart.js v4 charts (daily minutes bar, pages/day line — chunked via dynamic import so main.js stays untouched), per-library breakdown, most-read list, empty-state explainer. /analytics now 301s to /stats. The orphaned analytics.templ + analytics.ts removed (their containers and the page JSON never matched; the page was astub). - Dashboard 'This Week' widget (server-rendered, suppressed on service failure) and the book detail 'Your Reading Stats' card (lifetime totals of the viewer's own sessions) complete the tiers: per-user default, per-library breakdown inline, per-book on the page, per-system/admin aggregate parked as before. Tests: statistics_test.go (capture semantics at the chokepoint, tz/day buckets, zero-fill, streak math, finished detection, range validation, auth gate, widget, per-book lifetime). Full suite PASS.

📱 Multi-Library: Organize your ebooks, comics, and manga with per-library folders and smart collections.
🎨 Beautiful UI: 11 gorgeous dark themes with responsive design that works on any device.
🔒 Secure: JWT authentication, bcrypt password hashing, rate limiting, and no passwords on devices.
🚀 Quick Start
Prerequisites
- Podman (recommended) or Docker
- 5 minutes of your time
Installation
# 1. Clone the repository
git clone https://git.linuxhg.com/Bookhoard/bookhoard.git
cd bookhoard
# 2. Set up environment
cp .env.example .env
# Generate secure passwords (no special characters):
# JWT_SECRET: openssl rand -hex 32
# DBPASS: openssl rand -hex 16
# Edit .env with your generated values
# 3. Pull images and start the server
docker compose pull
docker compose up -d
# Optionally pin a specific version: set IMAGE_TAG in .env (defaults to "latest")
# 4. Open your browser
open http://localhost:8765
The first user to register automatically becomes an admin.

💾 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.
