 # Pinakes Android — Build Status
 
+## 1.8.0 (versionCode 22): circulation desk, book tools and plugin content for staff
+
+Requires Mobile API 1.7.0. Every area is gated on its own `/health` flag (`staff_circulation`, `staff_copies`, `staff_series`, `staff_merges`, `staff_labels`, `staff_imports`, `staff_covers`, `staff_desiderata`, `staff_archives`) plus the staff role and `staff_catalog`; a server that answers `false` or omits a flag keeps the 1.7.0 staff area for that part. The 403 `forbidden` contract is unchanged: every new call goes through the shared `staffCall`, which drops the stored role.
+
+- **Circulation desk** (hidden, never disabled, while the device is offline; an open desk screen closes when the connection drops): counters of the day, loans by bucket (requests, to pick up, scheduled, on loan, overdue, history) with search and multi-select bulk extend/recall, loan detail with the server's actions (approve, reject with reason, confirm/cancel pickup, return with the copy's outcome and a validated penalty, renew, edit user and dates, reminder, receipt PDF read in the app or shared through the FileProvider, receipt by email), new loan and new reservation (borrower search with eligibility, book search or a scanned copy code, per-user availability calendar, hand over now), reservations grouped by title (edit dates, cancel with reason, reactivate), borrower page. Creates carry an `Idempotency-Key` (one per submission, kept across the automatic retry after a dropped connection or a 409 `concurrent_retry`, discarded after success or `idempotency_conflict`).
+- **Copy scanner**: the same CameraX + ZXing pipeline reading CODE 128 and CODE 39 inventory labels (and EAN-13); manual code entry always visible; the sheet shows the copy and its open loan, then returns it with an outcome, lends it, or opens the book or the loan.
+- **Book tools**: per-copy list in the book editor (state, notes, delete with the server's refusal reasons, a copy with its own inventory code), book and copy label PDFs and the label settings sheet; series tree with search, details, rename (an existing name asks before merging), merge, delete, parent work, book numbers, removal and multi-select assignment; duplicate merges (suggested author groups or manual pick, publishers, genres); CSV and LibraryThing imports picked with the system document picker and run chunk by chunk from the server's progress (out-of-order recovery, busy retry, resumable after process death, pause/resume/cancel, error lines, past imports with their error CSV); missing covers fetched one book at a time with progress and the rate limit honoured; server-side cover sync and enrichment batches on the long-timeout client behind a confirmation; automatic enrichment switch.
+- **Plugin content**: Desiderata offers by status (accept, reject, receive into the wanted title or a picked record, delete) and wanted titles marked received; Archives units (published or not) created and edited with the plugin's rules checked client-side, publish switch, authorities with roles, cover and document uploads, delete; authority records list and editor.
+- Local verification: 377 debug unit tests (new: tolerant 1.7.0 parsing, loan actions, penalty validation, copy codes and export file names, staff areas × flags × connectivity, idempotency keys, series tree and series/label forms, import chunk rules, archive/authority forms and offer actions), zero lint errors (111 warnings, all pre-existing), debug and R8 release builds.
+- Device tests: 92 instrumented tests on Android 15 (`staffe2e` with `FakePinakes`). New flows: return as damaged with penalty, invalid penalty not sent, borrower page, 409 message, new loan with user search and Idempotency-Key, ineligible borrower, return by typed copy code, unknown code, reservation cancel and create, circulation hidden offline and restored, desk screen closing offline, no section without flags; copy edit, refused delete, copy with code, taken code; series number and rename clash merge; suggested author merge; import resume with out-of-order recovery and an upload through the real system document picker; covers loop and enrichment switch; desiderata receive (linked and into a picked record) and closed offer; archive publish keeping every field and create after validation; a retried merge already done; digital upload through the system picker and its absence without the flag; review regressions (bulk recall in batches with Select all, reservation paging, an authority that failed to load cannot be saved, a failed duplicate list with Retry, an import that ended elsewhere is not resumable, exports deleted on sign out); Tier 2 (a typed issue code received, a masthead's issues and a new year, a club created and a member's role changed, a workflow edited, a work created with an expression and a linked book, no Tier 2 rows without their flags).
+- Live smoke (`tools/e2e/live_smoke.py`) gains: loan created by API with an Idempotency-Key and its replay then returned in the app by typing the copy code, a copy with an explicit code from the book editor, a series created in the app, a two-row CSV import followed to completion, a free Desiderata offer received into a picked record, an unpublished archive unit absent from the public list. Each phase 2 step is skipped while its flag is off; cleanup returns loans the run left open and deletes only the books, series, units and offers the run created. Tier 2 steps: an unknown code at the periodicals desk (read-only, the bridge has no deletes), a book club and an FRBR work created in the app (deleted in cleanup). Run on 2026-10-14 against the local server (Mobile API 1.7.0 branch, every staff flag on) on an Android 15 emulator: 19 passed, 0 skipped, 0 failed.
+- **Tier 2** (each behind its own flag: `staff_periodicals`, `staff_bookclub`, `staff_frbr`, `staff_digital_library`): periodicals desk (scan or type an arriving issue's barcode, then receive or claim it; mastheads with years, issue states, new years and issues, subscriptions); book club management (create, settings, reading workflow with reorderable states and voting/reading/archived marks, members' role and membership state, adding a borrower, delete); FRBR works (search, create, edit, delete, expressions, link and unlink books); eBook and audiobook upload from the book editor (streamed, long-timeout client). The periodicals bridge has no article routes, so articles stay on the website.
+
+## 1.7.0 (versionCode 20): staff catalogue, offline catalogue, loans calendar
+
+Requires Mobile API 1.6.0 (Pinakes 0.8.5). Every new entry point is gated on the matching `/health` feature, so an older server keeps showing exactly the 1.6.2 app.
+
+- **Staff area** (`staff_catalog` + role `admin`/`staff`, refreshed from login and `GET /me`; a 403 on any staff call drops the stored role and leaves the screen): Profile → Staff area, and a scan button on the Catalog tab. Books (list with search, edit, delete with the active-circulation refusal), a shared create/edit form for records with or without an ISBN (identifiers validated live, authors/publishers pickers with "add new", genre/subgenre, shelf/level with automatic position, cover from URL / photo / picked image, copies), authors, publishers, genres (tree, find-or-create) and shelves/levels. Edits are true patches: only changed fields are sent.
+- **ISBN scanner**: CameraX + ZXing EAN-13 (no Play services), checksum validation, two identical reads before a lookup, 3 s suppression, batch mode with remembered copies, shelf/level and optional auto-confirm, preview / duplicate ("add copies", "open existing") / not-found sheets. Manual ISBN/EAN entry is always visible (emulators, denied permission). CAMERA is requested only there, with rationale and a settings fallback; `camera.any` is optional.
+- **Offline catalogue**: Room v2 holds the whole catalogue, kept current by `GET /catalog/sync` (delta with a server watermark, forced full resync every 7 days or when the server asks); loans, reservations and wishlist are written through on every fetch. Without a connection, search, book pages, Library and Wishlist answer from the cache with an offline banner. Loan and reservation actions are hidden offline (never shown disabled) and cached availability is shown only as "last known on <sync time>". The cache is excluded from backups.
+- **Loans calendar**: Profile → Loans in your calendar (`calendar_feed`): create the private ICS link, copy it (primary, Google Calendar can only subscribe from its website), open it as `webcal://` with an HTTPS fallback, regenerate (old link stops) or turn it off.
+- Local verification: 283 debug unit tests (new: ISBN/EAN codec, scan debouncer, staff access, staff form and write bodies, sync merge, offline policy, calendar links, tolerant 1.6.0 parsing, Room v2 catalogue/library DAOs), zero lint errors (111 warnings, mostly newer-dependency notices), debug and R8 release builds.
+- Device tests (re-runnable): `app/src/androidTest/java/com/pinakes/app/staffe2e/` drives the real app (MainActivity, real Hilt graph, ViewModels, Room) against `FakePinakes`, a MockWebServer on the device loopback answering JSON fixtures from `app/src/androidTest/assets/fixtures/` and recording every request. Covered: staff entry only for admin/staff with `staff_catalog` (hidden for standard users, for the flag off and after a server-side downgrade, header included); scanner manual ISBN → preview → add → counter, duplicate → add copies, not found → manual form with the code, invalid code rejected, camera denied keeps manual entry (the camera prompt is denied through UiAutomator); manual form title required and shelf-without-level both send nothing, edit sends only the changed key (recorded PUT body); offline search banner with cached results and no availability or loan actions, offline detail "last known" wording without loan buttons, Library/Wishlist offline empty state with no raw exception, going offline after an online load hides the loan button and coming back restores it (real airplane mode); calendar create → masked link, copy flagged sensitive, regenerate and turn off both confirm; gender and tax code absent from the profile editor when the library hides them (present when shown) and never asked at registration; author detail with the padded info card and the author's books (`author_id` sent); loan-calendar month (7 weekday columns, every day cell inside the screen and inside a 320dp column, month navigation) and the birth-date picker within a 360dp screen. Run on a disposable emulator (it replaces the app's stored session and cache): `ANDROID_SERIAL=emulator-5554 ./gradlew connectedDebugAndroidTest` (one class: add `-Pandroid.testInstrumentationRunnerArguments.class=com.pinakes.app.staffe2e.ScannerFlowTest`).
+- Live smoke (real app, real server): `tools/e2e/live-smoke.sh [--install]` with `PINAKES_E2E_URL` (as the device reaches it, e.g. `http://10.0.2.2:8081`), `PINAKES_E2E_EMAIL`, `PINAKES_E2E_PASSWORD` (admin or staff), optional `PINAKES_E2E_HOST_URL`, `PINAKES_E2E_ISBN` (default 9788845292613, must not be catalogued) and `ANDROID_SERIAL`. It clears the app, onboards, signs in, opens the staff hub, scan-adds an ISBN with 2 copies, adds a copy through the duplicate sheet, creates a record without ISBN, sets its shelf/level (skipped when the instance has none) and checks nothing else changed, searches and opens it in airplane mode, creates the calendar link and fetches the feed, and (with `PINAKES_E2E_DB_NAME/USER/PASSWORD/SOCKET` or `_HOST/_PORT`) hides gender and tax code in the settings table, checks they vanish from `/me` and from the profile editor, then restores the previous values; every step is checked through the API. Cleanup removes only what the run created (books, a calendar link that did not exist before, device tokens issued during the run) and clears the app. Texts follow the device language through `i18n/*.json`; `tools/e2e/ui.py` is the adb/uiautomator driver (`python3 tools/e2e/ui.py dump`).
+- Not covered by automation: real camera decoding and photo capture (emulators have no barcode in view).
+
 ## 2026 restyle (2026-10-08)
 
 The app now uses the 2026 web design: Geist / Fraunces, warm neutrals, a server-ready `ThemePalette`, complete 3D book covers, a searchable home hero with a cover fan, catalog grid/list views, dot status pills, grouped availability/actions and one card per exposed digital asset. Shared tokens apply to all existing account and plugin screens. The five-section bottom navigation is retained. Article lists and details now show server-resolved covers, subtitles, published online resources and access conditions, with a website action for the existing staff management flows. Native collections require the additive Mobile API 1.5.0 server update; existing circulation and authentication routes are retained.

 - Android: 185 unit test, 19 test Compose su Android 15, zero errori Lint; build debug e release R8 riuscite. Test senza donazioni o modifiche al catalogo Bibliodoc di produzione.
 - Backend richiesto: Mobile API 1.5.0 e plugin aggiornati (Desiderata 1.2.0, Emeroteca 1.13.0, Archives 1.5.1). Le nuove sezioni dipendono dalle capability del server. Un server precedente continua a funzionare, ma non offre la nuova API delle raccolte; per i filtri analitici non supportati l’app richiede l’aggiornamento.
 - La gestione amministrativa e gli upload degli articoli/archivi aprono il PHP protetto nel browser. Non sono nuovi editor CRUD nativi.
+- Aggiornamento 1.7.0 (Mobile API 1.6.0): per libri, autori, editori, generi e scaffali la gestione staff è ora nativa (lettore ISBN con modalità in serie, scheda manuale per materiale senza ISBN, copie, copertina). Articoli, archivi, utenti, prestiti e impostazioni restano sulle pagine PHP protette. Il catalogo è consultabile offline e i prestiti si possono sottoscrivere come calendario personale.
+- Aggiornamento 1.8.0 (Mobile API 1.7.0): diventano native anche la circolazione (banco prestiti con contatori, richieste, ritiri, prestiti attivi e scaduti, storico, restituzione con esito e sanzione anche da codice copia scansionato, rinnovo, proroga e solleciti multipli, ricevuta PDF, nuovi prestiti e prenotazioni con calendario per utente), la gestione per singola copia con etichette, le collane, l’unione dei duplicati, l’importazione CSV e LibraryThing, copertine e arricchimento, le proposte Desiderata e le schede d’archivio con autorità e allegati. La circolazione sparisce senza connessione. Anche il banco emeroteca (ricezione e reclamo dei fascicoli da codice a barre, annate, fascicoli, abbonamenti), la gestione dei gruppi di lettura (impostazioni, percorso di lettura, membri) e le opere FRBR (espressioni, libri collegati) sono native. Restano sul web: utenti, impostazioni generali e gli articoli dell’emeroteca.
 - [#52](https://github.com/fabiodalez-dev/Pinakes/issues/52), import danese FBI/DBC, resta una richiesta separata non implementata: token e documentazione completa richiedono accesso DBC, che non è disponibile in questa sessione. Non è una funzionalità già presente nel server da sincronizzare.
 - [#57](https://github.com/fabiodalez-dev/Pinakes/issues/57) descrive l’installazione dell’estensione YAZ nel container QNAP; Uwe precisa che non è un difetto Pinakes. Non viene dichiarata risolta modificando il client Android.
 - Nessuna merge, pubblicazione sugli store o distribuzione in produzione effettuata. Il caso ANR sul vecchio emulatore GUI resta distinto dai test riusciti sull’AVD headless; non si dichiara risolto un ANR su dispositivi reali.

+"""Live end-to-end smoke test: the real app on an emulator against a real Pinakes instance.
+
+Drives the installed debug app with adb/uiautomator (``ui.py``) like a user, checks the
+server state through the Mobile API after every step, and removes what it created.
+
+Environment (nothing is hardcoded, secrets are never printed):
+  PINAKES_E2E_URL       instance URL as the device reaches it (emulator: http://10.0.2.2:8081)
+  PINAKES_E2E_HOST_URL  same instance as this machine reaches it (default: the device URL
+                        with 10.0.2.2 replaced by 127.0.0.1)
+  PINAKES_E2E_EMAIL     an admin or staff account
+  PINAKES_E2E_PASSWORD  its password
+  PINAKES_E2E_ISBN      ISBN to scan-add (default 9788845292613); must not be in the catalogue
+  ANDROID_SERIAL        target device (adb's own variable)
+
+Optional, for the "hidden profile fields" step (skipped without them): direct access to the
+instance database, used to switch the gender / tax code visibility and restore it afterwards.
+  PINAKES_E2E_DB_NAME, PINAKES_E2E_DB_USER, PINAKES_E2E_DB_PASSWORD,
+  PINAKES_E2E_DB_SOCKET (or PINAKES_E2E_DB_HOST + PINAKES_E2E_DB_PORT)
+
+Steps: onboarding URL, login, staff hub, manual ISBN add (scraped preview), duplicate add
+copies, manual record without ISBN, shelf/level location on edit (skipped when the instance
+has no shelf with a level), phase 2 (each skipped while its /health staff_* flag is off):
+loan created by API with an Idempotency-Key and its replay, then returned in the app by
+typing the copy code; a copy with an explicit code from the book editor; a series created in
+the app; a two-row CSV import job followed to completion; a free Desiderata offer received into a picked record; an
+unpublished archive unit created and checked absent from the public list; Tier 2: an unknown
+code looked up at the periodicals desk (read-only), a book club and an FRBR work created in the
+app; then airplane-mode
+offline search and detail, calendar link + feed.
+Cleanup (only what this run created): created books deleted, the calendar link revoked when
+it did not exist before, device tokens issued during the run revoked, app data cleared,
+airplane mode off. Exit code 0 only when every step passed.
