Consolidates two long-standing feature branches, rebased onto 0.7.64 and cleaned up, into 0.7.65.

Features

Add-to-calendar links in loan emails. The loan-approved and pickup-ready emails carry a calendar block: a Google Calendar link plus a tokenized per-loan .ics download, so a borrower can save the due date in any calendar app — multi-calendar, no account linking, no OAuth (this is the ICS approach discussed under #238). Rendered by NotificationService via a new LoanCalendarLinks helper; IcsGenerator gains the per-loan VEVENT. Upgraded installs get the {{sezione_calendario}} placeholder appended to already-seeded templates by an idempotent email_templates migration; fresh installs from the template defaults. Strings translated in all five locales.

Public SEO pass. Canonical URLs strip tracking query strings; hreflang and locale-prefixed sitemap URLs no longer advertise non-routable 404s; author/publisher/genre archives share a localized SEO block with canonical + CollectionPage/Person/BreadcrumbList JSON-LD; book pages brand their Library schema with app.name; search and standalone auth pages carry noindex,follow; catalog pagination is server-rendered and crawlable; grid covers lazy-load and the LCP cover gets fetchpriority="high"; meta descriptions are cut multibyte-safe; public events emit Event + BreadcrumbList JSON-LD.

Fix

#366 residual (the state reported by @Himura2la after the 0.7.63 Docker upgrade). Legacy da_ritirare rows with a NULL pickup_deadline could stay "ready for pickup" forever — the expiry sweep skips NULL deadlines and the 0.7.63 repair deliberately preserves a pickup whose copy is free. PickupDeadlineBackfill runs on every upgrade after reapplyTriggers() (PHP, not SQL, so it isn't aborted by the starting version's overlap trigger), assigning today + pickup_expiry_days capped at the loan's data_scadenza; rows whose window already closed get a past deadline and are culled by the next sweep.

Tests

Origin: two abandoned branches (calendar-links + SEO review), rebased clean and de-duplicated onto current main; version bumped 0.7.64 → 0.7.65.

Loan approval and pickup-ready emails carry a {{sezione_calendario}} block
with a Google Calendar link and a tokenized per-loan .ics download, rendered
by NotificationService via a new LoanCalendarLinks helper. IcsGenerator gains
the per-loan VEVENT, and the strings are translated in all five locales.
SEO: canonical URLs strip tracking params; hreflang/locale-prefixed sitemap
URLs no longer advertise non-routable 404s; author/publisher/genre archives
share a localized SEO block with canonical + CollectionPage/BreadcrumbList
JSON-LD; crawlable server-rendered catalog pagination, lazy grid covers and
fetchpriority on the LCP cover; noindex on search/auth pages; Event JSON-LD.

Fix #366: PickupDeadlineBackfill backfills a pickup_deadline on legacy
da_ritirare rows left with NULL (which the expiry sweep skipped and the 0.7.63
repair preserved), so they finally expire. Wired into Updater::runMigrations()
after reapplyTriggers() — not a SQL migration — so it runs under the corrected
trigger. Bump to 0.7.65 with migrate_0.7.65-rc.1.sql for the calendar template.
The calendar-links email_templates update ships as migrate_0.7.65-rc.1.sql
(point the calendar test at it), and the #366 backfill guard now asserts that
no 0.7.65 SQL migration touches prestiti — rather than that none exists —
since the calendar migration legitimately does (on email_templates).

📝 Walkthrough

Walkthrough

La release 0.7.65 aggiunge i link calendario alle email dei prestiti, ripara le scadenze legacy durante gli aggiornamenti e applica modifiche SEO a canonical, sitemap, robots, archivi, paginazione, immagini e dati strutturati.

Changes

Link calendario e dati legacy

Layer / File(s) Summary
Link calendario nelle email e download ICS
app/Support/LoanCalendarLinks.php, app/Support/IcsGenerator.php, app/Support/NotificationService.php, app/Routes/web.php, app/Support/EmailService.php, app/Support/SettingsMailTemplates.php, app/Support/mail_templates/*, locale/*, installer/database/migrations/migrate_0.7.65-rc.1.sql, tests/loan-calendar-links.unit.php
Le email loan_approved e loan_pickup_ready includono link Google Calendar e download .ics. Il download usa token HMAC e genera un evento per il prestito.
Backfill delle scadenze di ritiro
app/Support/PickupDeadlineBackfill.php, app/Support/Updater.php, tests/migration-0.7.65-rc.1.unit.php, CHANGELOG.md
L’aggiornamento calcola pickup_deadline per le righe legacy da_ritirare e limita la data a data_scadenza. Il test verifica idempotenza, errori e righe escluse.

SEO e navigazione

Layer / File(s) Summary
Canonical, indicizzazione e dati strutturati
app/Views/frontend/*, app/Views/auth/*, app/Controllers/FrontendController.php, app/Controllers/SeoController.php, app/Support/SitemapGenerator.php, app/Support/HreflangHelper.php, app/Support/HtmlHelper.php, tests/seo-feed.spec.js
La gestione SEO centralizza gli archivi, rimuove gli alternati hreflang, usa la lingua predefinita nella sitemap, aggiorna robots e canonical, aggiunge noindex, migliora la paginazione e inserisce dati strutturati.
Documentazione e metadati di release
CHANGELOG.md, docs/SEO_IMPLEMENTATION_TESTING.md, docs/SEO_REVIEW_2026-08-21.MD, version.json
La documentazione descrive il comportamento SEO aggiornato. Il changelog registra la release 0.7.65 e version.json aggiorna la versione del progetto.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 98072

This release changes public sitemap generation, SEO URLs, loan-calendar files, and pickup-deadline repair behavior. Current issues can cause excessive resource use, incomplete indexing, malformed search URLs, inaccurate calendar events, or legacy loans remaining unrepaired while appearing successful, so the PR needs follow-up or explicit owner acceptance before merging.

Inline comments:
In `@app/Support/IcsGenerator.php`:
- Around line 65-99: Update generateForLoan to apply the same end-date handling
used by fetchEvents: when the loan status is in_ritardo, use today’s date in the
application timezone as the event end instead of data_scadenza; preserve
data_scadenza for other statuses and pass the adjusted value through
formatEvent.

In `@app/Support/LoanCalendarLinks.php`:
- Around line 56-59: Aggiungi in RouteTranslator la chiave calendar_loan con il
placeholder {id}, quindi aggiorna icsUrl per ottenere il percorso tramite
RouteTranslator::route('calendar_loan'), sostituire {id} con loanId e mantenere
invariata la costruzione dell’URL assoluto e del token.

In `@app/Support/NotificationService.php`:
- Around line 1427-1428: Update buildCalendarSection and both call sites in
sendLoanApprovedNotification and sendPickupReadyNotification to accept and pass
recipientLocale, then use that value instead of I18n::getInstallationLocale()
when translating the calendar section. Preserve the existing locale resolution
and ensure the calendar content matches the rest of each recipient’s email.

In `@app/Support/PickupDeadlineBackfill.php`:
- Around line 65-67: Gestisci il valore restituito da mysqli_stmt::execute() nel
backfill: se l’esecuzione fallisce, restituisci false immediatamente prima di
leggere affected_rows; assegna $repaired solo dopo un’esecuzione riuscita, così
Updater::runMigrations() può rilevare il fallimento della migrazione.

In `@app/Support/SitemapGenerator.php`:
- Around line 26-31: Update generate() to enforce a global URL cap across books,
authors, publishers, and genres before appending entries, preserving the sitemap
protocol limit and existing per-section caps. Ensure every URL source
participates in the same remaining-capacity calculation so the resulting Urlset
cannot exceed the allowed total.
- Around line 366-390: Update the publisher query used by the sitemap generation
flow around the publisher entry loop so publishers with books in libri_editori
are included, matching FrontendController::publisherArchive(). Preserve the
primary-editor relationship and add the secondary-editor EXISTS condition only
when SchemaInfo::hasLibriEditori() is available, while retaining the existing
visibility and empty-name filtering.

In `@app/Views/frontend/layout.php`:
- Around line 154-158: Update the canonical link’s href expression in the layout
to call htmlspecialchars with ENT_QUOTES and UTF-8, matching the explicit
escaping already used for seoRobots and ensuring every URL rendered in href is
escaped consistently.

In `@docs/SEO_IMPLEMENTATION_TESTING.md`:
- Around line 84-99: Update the introductory hreflang guidance near the
document’s opening to state that hreflang is disabled and not emitted, matching
the behavior documented in the section around Hreflang and SitemapGenerator.
Remove any instructions claiming path-prefixed hreflang URLs are implemented so
the testing procedure is consistent.

In `@tests/migration-0.7.65-rc.1.unit.php`:
- Around line 59-60: Update the test date setup around $today and $plus to
derive the reference date from SELECT CURDATE() using the same MySQL connection
as PickupDeadlineBackfill::run(). Parse that returned date and base both $today
and the $plus calculations on it, rather than creating dates from PHP’s default
timezone.

The server-rendered pagination read $current_page, which the controller never
set (it tracks $page), so the no-JS nav always marked page 1 active and never
linked past page 5 — pages 6+ were not crawlable, defeating the feature. The
controller now passes $current_page, the view declares it, and the catalog
canonical self-canonicalizes ?page=N (matching the archive policy) so books
reachable only on later pages stay indexable instead of collapsing onto page 1.
- IcsGenerator::generateForLoan extends an overdue loan's event end to today
  (mirrors fetchEvents), so a stale .ics no longer shows the copy as free.
- buildCalendarSection renders in the recipient's locale, not the install one,
  so the calendar block matches the rest of each email.
- PickupDeadlineBackfill returns false on a failed execute() before reading
  affected_rows, so the Updater sees the failure.
- Sitemap: publishers reachable only as secondary editors (libri_editori) are
  listed, matching publisherArchive; a global 50k-URL cap keeps the file valid.
- Canonical href uses htmlspecialchars(ENT_QUOTES, UTF-8).
- Doc intro corrected to say hreflang is no longer emitted (0.7.65).
- The #366 backfill test derives its reference date from MySQL CURDATE().
The SEO pass disables hreflang (it pointed to non-routable locale-prefixed
404s), but seo-feed.spec.js still asserted the presence of path-prefixed
alternates and failed the browser-regression shard. Replace the six presence
tests with three that lock the 'no hreflang' contract on home, catalog and a
book page.

default-locale sitemap URLs are expected. Remove obsolete requirements for
hreflang tags and locale-prefixed alternate URLs while preserving the documented
active endpoint and SEO behavior.

Comment thread app/Views/frontend/catalog.php
Comment thread docs/SEO_IMPLEMENTATION_TESTING.md
- SitemapGenerator now passes the remaining capacity to each large section and
  applies a SQL LIMIT, so publisher/genre queries can no longer allocate past
  the 50k sitemap-protocol ceiling before truncation; collection stops early.
- catalog SearchAction urlTemplate is built from the un-paginated catalog URL,
  so a page>1 canonical (?page=N) no longer yields ?page=N?q={search_term}.
- SEO testing doc: the remaining hreflang procedures now verify absence, not
  presence, consistent with hreflang being disabled since 0.7.65.
wrapCalendar() published $this->timezone (the constructor value) while
formatEvent() renders events in appTimezone() (the configured app.timezone).
If they differ the calendar metadata contradicts the event times; emit the
resolved appTimezone name instead.
