VisibleLibrarySet becomes a package-level function taking the queries
(db-only services like statistics reach it without new wiring); the
LibraryService method stays as the ergonomic entry point. Statistics'
ids-shaper and the reader pages' three hand-rolled membership loops
(empty-rows fallback then linear scans) now delegate; the gates keep
their 403-on-invisible semantics (>null set membership, never silent
pass).
Census addendum from this pass: two OPDS sites call
GetUserVisibleLibraries directly but consume FULL ROWS (per-library
folder enumeration) — a third legitimate pattern alongside set/ids and
resolveLibrary's active-selection; documented, untouched. The library
LIST endpoint and its SSR data helper are row consumers too, by design.
checkRulesAgainstBook/evaluateRule and the service's EvaluateRules
existed in two parallel universes: one over database.MediaItems (what
every query actually returns) and one over ListMediaItemsRow (what two
hand-written 45-field mediaItemsToListMediaItemsRow converters
produced — verbatim twins in the handler and the dashboard service,
with a URL-resolution side effect baked into a "converter"). The rule
fields (genre/series/author/language/publisher/copyright_year/tags)
all exist on MediaItems, so the evaluators now take the real row and
the converters, their three call-site loops, and the dead
ApplyAutoAssignRules entry point (zero callers) are gone.
The rules surface is wire-covered by the collections rules scenarios;
handlers+services suites and the full pin/H1/H3 battery green.
The /stats page gains a second tab (Reading | Library) implementing the
Audiobookshelf-style library dashboard (HANDOFF item 9): media_items
INVENTORY aggregates — items, hours/pages, distinct authors, size,
distinct narrators, Top Genres / Top Authors bars, Longest / Largest
items — for one library or the All-libraries aggregate.
- GET /api/stats/library-usage?library_id=<uuid|omit>; family lens
enforced: a library_id outside the requester's visible set is a 403,
never a silent pass (AGENTS.md standing rule; 431fec0 history)
- six sqlc queries with the visibility pattern + healthy-item filter
(archived_at IS NULL AND missing_scan_count = 0); hours_mode lets the
client swap the Hours/Pages card and the Longest ranking per scope
- Reading tab unit audit (HANDOFF item 3, settled 2026-10-16): minutes
are the merged currency everywhere honest; only the PAGES unit splits
— Pages card goes mode-aware (Pages · text / Listening Time in an
audio-only pool) and the charts row gains Listening per Day (hrs)
when audio minutes exist in the range; summary daily buckets gain
audio_minutes split by the item's library type
- tab state in the URL (?tab=library&library_id=…); selector fed by the
existing /api/libraries/visibility endpoint; main.js?v=4
- integration tests: family-lens 403 pin, hidden-library exclusion
(differential), seeded text+audio aggregate correctness, auth gate
- docs/developer/api/stats/get_library_usage.md
Known-remaining suite failures are environmental: TestConflictList_Empty
+ TestWebSocketPingPong collide with the concurrently-running app session
(live emulator pushes + scans on the shared dev DB), and
TestAdminCreateUser's timezone expectation drifted from live system
settings — all three fail on the clean tree too.
A2a (metadata round): narrators TEXT[] + narrators_search (tags
pattern: accumulator + GIN pairs) + abridged bool on media_items;
scanner fills from the Libation/ABS sidecar (narrators verbatim,
abridged flag) with audio-payload promotion; editorial fields ride
the real columns while audio_metadata stays scan-derived (duration/
codec/chapters). Detail/edit/save paths carry the fields; the web
edit dialog grows an Audio section (Narrator(s) comma-input, Abridged
toggle, scanned duration read-only); search weights + narrator filter
(word_similarity over narrators_search) + narrator autocomplete added.
A2c (per-media-type wording): copy helpers keyed on format_group —
Listen Now, Mark Complete/Not Complete, Listening Progress, Your
Listening Stats, Time Listening, Time listened (pages tile swapped for
audio), Position H:MM:SS / total H:MM:SS on detail + progress pages
(duration parsed from audio_metadata). Dashboard: system collections
swap to Continue Listening / Recently Listened at DISPLAY time when
the audiobooks library is selected (stored names unchanged; restores
keep working); week card = Listening Time / Sessions / Books Touched;
cover-corner badges identify audiobook (headphones) / comic / manga
cards on mixed grids — books stay unbadged; hover action icon follows
the media type.
A2b (player): the scrubber binds value to the playhead with an explicit
scrub guard (the handle previously froze at its initial max); header
row = reader-style back arrow + Chapter n/total launcher; chapters
open in a floating top-down drawer (current chapter highlighted, page
never shifts); Skip/Speed rows share one label-left layout; honest
wall-clock session accounting (playing-only deltas, paused flush).
A2d (bookmarks): note-bearing time bookmarks ride the existing
media_bookmarks substrate (notes column + sync-aware service already
there) — audio locator convention audio:<seconds>, chapter_number
filled, auto-title '<chapter> — H:MM:SS', capture popover with optional
note, drawer with jump/edit-note/delete. Zero server changes needed.
Verified live on the Libation sample: narrators backfilled by rescan;
PUT edit persisted + overrides detected (narrators, abridged); force
rescan preserved the user edit; reset-to-scanned-of-defaults restored
truth; narrator filter/autocomplete scoped by library; dashboard
listsening wording + badges render; bookmark save with note deduped to
one row.
Phase 1 (foundation): 'audiobooks' library type seeded (schema + DB);
audio_metadata JSONB on media_items (the kobo_metadata precedent —
only audio paths read it); reading_progress.audio_offset_seconds for
the honest {chapter, offset} locator; extensions/mimes registered for
ALL breadth formats (m4b/m4a/mp3/flac — deliberate per the DOC/LIT
doctrine, m4b scans richly first); classifyFormatGroup 'audiobook'
case (gotcha 39 recomputes on rescan); Go mime table extended at boot
so media elements accept the streams; ffmpeg/ffprobe in the image
(8.1.2 — also the xHE-AAC identification tripwire).
Phase 2 (ingest): sidecar-first (Libation/ABS metadata.json —
narrators/ASIN/curated chapters), ffprobe fallback/filler (duration,
bitrate, codec/profile, embedded chapters). Fixed three real
parser brittlenesses the Libation sidecar exposed: series accepts
string OR array-of-objects, publishedYear accepts number OR string,
ffprobe chapter timings accept number OR string (flexFloat). Folder-
structure fallback now runs on the UPDATE path too (rescans were
clearing sidecar-absent series/author); audio facts re-derive on
every rescan (gotcha 39).
Phase 3 (playback + sync): GET /api/media-items/:id/chapters (the
format-abstraction list); streaming rides the existing cookie-authed
Range /uploads path; PUT progress carries audio_offset_seconds +
elapsed_seconds (honest wall-clock playing time) — the reading-
history capture prefers player-reported elapsed over the inter-push
delta, same 2h ceiling; reading_mode='audio' marks the row.
Phase 4 (web player): dedicated audio reader page (foliate not
involved) — cover, chapter title, whole-book scrubber, skip ± (chips
1/5/10/15/30s, default 10s), speed (0.75×–2×), chapter list with
jump-to, Media Session lockscreen/notification transport, periodic
playing-only progress pushes, position restore on open.
Verified live: ingest of the Libation sample (Gardens of the Moon —
title/author/series/cover/date from sidecar+folders, 34 chapters,
26h duration, aac/LC); chapters endpoint; the reader route serving
the player; playback with position restore (0:57 round-trip);
progress rows in audio mode; wall-clock session rows in
reading_history.
Three dashboard complaints, one build:
- The widget collapses to a single summary row (This Week · minutes ·
pages · sessions · books · streak · Full stats) on every screen size
and expands to the full grid via a details/summary toggle — the
carousel sections start immediately below it again.
- The 'Your Library' heading moved into the library switcher subbar
(LibrarySwitcher gains an optional title param; collections/series
keep the plain 'Library' label). The standalone heading block is
gone.
- Root-caused the JS-switch vanishing: renderDashboardCollections
replaces ALL of #collections-container's innerHTML, so anything
server-rendered inside it (title, widget) died on the first library
switch. The widget now re-fetches ITSELF: a /dashboard/week-widget
fragment (same resolveLibrary family-lens rules as the page) is
pulled by htmx whenever the switcher dispatches week-refresh —
carrying the current #library-select value — so the widget both
survives switches and RE-SCOPES to the switched library. Initial SSR
renders the same scope the sections use.
ThisWeek (and the streak calendar) gained an optional library filter.
Tests: TestReadingStatsWeekLibraryScope — per-library totals, scoped
streaks, invisible-library isolation, malformed id 400. Full suite
PASS.
The bucket name read as confusing — 'unsynced' implied data loss when
the push is always captured; it only lacks a device credential. The
bucket is just 'Web' now (service fallback, stats.ts fallback, panel
copy, tests).
Also: analytics_test exact-zero assertions (EmptyHistory,
NoReadingHistory) ran against testuser, which is a LIVE reader — real
sessions accrued on it mid-suite and both flapped. They now run under
the fresh regular user, like the stats tests; the 'testuser is a live
reader' rule is recorded in AGENTS.md.
- Attribution: registered clients may now send their device token in
X-Device-Token on PUT /api/media-items/:id/progress (the user JWT
stays primary). The token must map to a device OWNED BY the caller —
foreign/invalid/absent tokens soft-fail to plain web attribution so a
stats decoration can never break a sync. Attributed pushes capture
device_id (FK-safe), device_metadata.source = the registered device
name ('Pixel 9', 'Kindle Paperwhite'), and last_sync surfaces show
that device. Side effect worth having: app-vs-web pushes used to be
LWW-invisible (both sources read 'web'); they now surface as
legitimate cross-source progress conflicts when they diverge.
- /stats gains a By Device panel alongside By Library (grid 3-wide):
reading minutes + sessions + books per registered device, plus one
Web / unsynced bucket for device-less pushes so the panel always
reconciles with the headline totals. Range-aware, family-lens
scoped; renderBars shared between panels in stats.ts.
- The device identity IS the registered platform: devices rows already
carry the name/type the client registered (app sends Build.MODEL +
'mobile' at /api/devices/register, KOReader/Kobo likewise) — no new
identity plumbing on the server.
Tests: capture attributed to the device (row device_id + source
metadata + last_sync_source), foreign/nonexistent tokens soft-fail,
device buckets reconcile (80 attributed + 75 unsynced = 155 total).
Full suite PASS.
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.
