Content-Transfer-Encoding: 8bit

First increment of the modern image pipeline (#109):
- New App\Services\Imaging\ImageEngine: capability-detected encoder.
  - libvips fast path (jcupitt/vips): shrink-on-load, low memory; emits
    jpeg/webp/avif/jxl when the build supports them.
  - capabilities(): detects vips, HEIC/HEIF read, AVIF/JPEG-XL write, and
    optimizer binaries (jpegoptim/pngquant/cwebp/avifenc).
  - optional post-encode optimization via proc_open argv-array (no shell).
- images:generate tries ImageEngine::encode() first, falling back to the
  existing Imagick/GD path when vips is unavailable: zero behaviour change
  on hosts without vips (verified: encode() returns false then fallback).
- Hardened orphan-variant deletion with a realpath confinement under
  public/media (path-traversal guard).

Activation needs composer require jcupitt/vips + php-vips/libvips built
with heif+aom (AVIF) and libjxl (JPEG-XL). Without them, behaviour is
unchanged. HEIC import and next-gen output formats follow on this branch.

+ * ImageEngine — modern, capability-detected variant encoder (#109).
+ *
+ * Foundation for the image-variant pipeline modernization. It provides:
+ *   - a fast, low-memory libvips path (jcupitt/vips) when the extension is
+ *     available, with automatic fallback to the caller's existing Imagick/GD
+ *     code when it is not (zero behaviour change on hosts without vips);
+ *   - capability detection (vips, HEIC/HEIF read, AVIF/JPEG-XL write,
+ *     post-encode optimizer binaries) surfaced for diagnostics;
+ *   - an optional post-encode optimization pass via CLI optimizers.
+ *
+ * Dependency-optional by design: vips classes are referenced only behind
+ * class_exists()/extension_loaded() guards, optimizer binaries only behind
+ * PATH detection, and every external command runs through proc_open() with an
+ * argv ARRAY (no shell, so no command injection). The package builds and runs
+ * unchanged before `composer require jcupitt/vips` and before any optimizer
+ * binary is installed. Heavy work runs from the CLI variant generator
+ * (`images:generate`), never inside a web request.

Subject: [PATCH 02/11] feat(imaging): HEIC import, settings-driven JPEG-XL,
 optimizer wiring, diagnostics (#109)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Completes the modern image pipeline on top of the ImageEngine foundation.

Ingestion / UploadService:
- Accept HEIC/HEIF uploads, gated on ImageEngine capabilities (heif_read)
  so we never store an original we can't turn into web variants. ISO-BMFF
  'ftyp' magic check; HEIC-aware dimension reading via Imagick pingImage
  (headers only — decompression-bomb safe) since getimagesize() can't read
  HEIC. Originals keep .heic/.heif; variants stay jpg/webp/avif.
- Wire ImageEngine fast path into resizeWithImagick / resizeWithImagickOrGd
  (libvips first, Imagick/GD fallback unchanged).

Variant generation:
- images:generate emits JPEG-XL when enabled in settings AND the build can
  write it (capability-gated; libvips engine). Order unchanged for the
  existing avif/webp/jpg.

Settings:
- image.formats/quality gain a jxl entry (default OFF); admin settings form
  + controller parse fmt_jxl/q_jxl.

Diagnostics:
- New "Imaging Engine" panel: active engine, libvips/Imagick/GD, HEIC read,
  AVIF/JPEG-XL write, detected optimizer binaries.

Security (per project policy — fix findings even when pre-existing):
- Confined orphan-variant + favicon deletions with realpath guards.
- Hardened the images:generate exec (realpath-validated console path,
  escapeshellarg, app-private reused log under storage/logs).

composer.json: suggest jcupitt/vips, ext-vips, ext-imagick,
spatie/image-optimizer (all optional; behaviour unchanged without them).

Verified end-to-end on a vips-less host: images:generate produced 15/15
variants (avif/webp/jpg) via the Imagick fallback, 0 errors.

Subject: [PATCH 03/11] fix: address image-pipeline review findings (#109)

Applies 10 confirmed findings from the code review of #117.

HEIC handling (cross-cutting group, app/Services):
- Centralize HEIC dimension reads via new ImageEngine::dimensions()
  (libvips header/sequential, bomb-safe); readImageDimensions() now
  tries vips before Imagick so vips-only hosts can measure admitted
  HEIC instead of rejecting it (F007/F008).
- Post-orientation re-read uses the HEIC-aware readImageDimensions()
  instead of bare getimagesize(), fixing swapped/stale dimensions for
  rotated HEIC originals (F006).
- HEIC uploads get an immediate sm preview via the HEIC-capable
  variant path when the GD-only generateJpegPreview() returns null
  (F009).

Encoder correctness (app/Services/UploadService.php, app/Tasks):
- Remove the redundant second ImageEngine::encode() on the
  Imagick fallback by extracting resizeWithImagickOnly() (F003).
- Thread STRIP_EXIF into the libvips encode() fast path so it honours
  STRIP_EXIF=false like the Imagick path (F012).

JPEG-XL data layer (database, app/Tasks):
- Allow 'jxl' in image_variants.format on both engines: widen the
  SQLite CHECK and MySQL ENUM, add migrate_1.4.13_{sqlite,mysql}.sql
  (SQLite via guarded table rebuild), regenerate template.sqlite, bump
  version to 1.4.13. Wrap the variant INSERT in try/catch so one bad
  row no longer aborts the whole images:generate run (F030).

Admin UI (app/Views, storage/translations, app/Controllers):
- i18n the JPEG-XL settings strings via trans() keys (F020).
- Fix the quality-inputs grid to grid-cols-4 so the 4th input aligns (F022).
- Diagnostics no longer reports "No capable image engine" when GD is
  present (F025).

+-- SQLite cannot ALTER a CHECK constraint in place, so we rebuild the table with
+-- the widened CHECK and copy the rows across. Each statement has NO inner
+-- semicolons so it passes cleanly through the migration runner's splitter.
+-- Column list + constraints mirror schema.sqlite.sql exactly (the table has no
+-- secondary indexes beyond the inline PK / UNIQUE).

Subject: [PATCH 04/11] fix: serve JPEG-XL + ImageEngine cleanup (walkthrough
 findings)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Applies 4 findings promoted via /adamsreview:walkthrough.

- F013: serve JPEG-XL to capable browsers. buildResponsiveSources()
  gains a 'jxl' bucket (avif > jxl > webp > jpg), and every <picture>
  template emits a <source type="image/jxl"> after avif when jxl
  variants exist (guarded exactly like avif, so jxl-disabled — the
  default — renders no empty source). Generation unchanged; LCP/Early
  Hints single-format preload stays on avif.
- F014: drop dead optimization paths. Remove the unreachable pngquant
  branch from ImageEngine::optimize() and stop detecting/surfacing
  opt_pngquant/opt_cwebp/opt_avifenc (never invoked); keep jpegoptim.
- F028: ImageEngine::optimize() is now private static (only the
  internal encode() pipeline calls it).
- F015: correct the encode() docstring — $format (not the $dest
  extension) selects the encoder.

Subject: [PATCH 05/11] test: protected-media security suite + 1.4.13 migration
 coverage

- Add MediaAccessSecurityTest: 4 comprehensive tests locking in the
  access-control invariants for NSFW-only, password-only, combined
  NSFW+password albums, plus the cross-cutting boundaries (per-album
  scoping, unpublished 404, path-traversal rejection, downloads-disabled
  original fallback). Each asserts the core invariant: a gated visitor
  may receive a generic blur placeholder but NEVER the real sharp
  variant bytes, while an authorized viewer gets the real bytes from
  no-store private storage. Access-control code is byte-identical to
  main; these tests guard it against regression.
- MigrationsTest: seed image_variants in its pre-1.4.13 shape so the new
  jxl-widening migration's table rebuild applies, and assert format='jxl'
  is accepted post-migration.

+/**
+ * Security regression suite for protected-media serving.
+ *
+ * Proves the access-control invariants for the three protection modes a
+ * photographer can put on an album — NSFW-only, password-only, and both
+ * combined — plus the cross-cutting boundaries (per-album scoping,
+ * unpublished albums, path traversal, downloads-disabled originals).
+ *
+ * The invariants asserted here are the ones that must NOT regress as the
+ * image pipeline (#109) and admin redesign evolve:
+ *
+ *   1. Sharp (non-blur) variants of a protected album are NEVER served to a
+ *      visitor who has not cleared the album's gate(s). Denial returns 403
+ *      (no blur, no original to fall back to) — never the real bytes.
+ *   2. When access IS granted, the variant is quarantined to
+ *      storage/protected-media/ (outside the web root) and served with
+ *      Cache-Control: no-store + X-Robots-Tag: noimageindex — never a
+ *      shared/public cache.
+ *   3. Blur variants are always public (they back cover images), so a
+ *      gate-less visitor still gets the blurred preview.
+ *   4. Both gates are independent AND conjunctive: a "both" album requires
+ *      the password session AND the NSFW consent; clearing only one is not
+ *      enough.
+ *   5. Access is scoped per-album: a session token for album A grants
+ *      nothing for album B.
+ *
+ * Mirrors the in-memory-SQLite + real-controller pattern of
+ * ProtectedMediaStorageTest so it exercises the actual MediaController
+ * code path (no mocks of the access logic).

Subject: [PATCH 06/11] feat(admin): add "Back to Pages" arrow on page editors
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The home/about/cookie/license/privacy editors under /admin/pages had no
way back to the page list except the browser button. Add a "← Back"
btn-secondary linking to /admin/pages in each editor's header action
group, matching the pattern already used in pages/galleries.twig
(trans key admin.pages.back, already present in both locales).

Subject: [PATCH 07/11] feat(media): serve JPEG-XL variants end-to-end
 (completes #109 F013)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The F013 template work emitted <source type="image/jxl"> URLs, but the
serving layer rejected the .jxl format, so those URLs 404'd on every
album (all /media/ traffic routes through MediaController). Wire jxl
through the full serve path:

- EXT_TO_MIME gains jxl => image/jxl.
- serveProtected format whitelist, servePublic filename regex +
  allowedMimes, serveResolvedFile + serveStaticFile allowedMimes all
  accept jxl.
- ProtectedMediaStorage::mediaBasename accepts .jxl so protected jxl
  variants resolve/quarantine like the others.
- Strict DB-path MIME gate: libmagic frequently can't identify JPEG-XL,
  which would spuriously fail the magic-byte cross-check. Verify the
  JXL signature directly (bare codestream 0xFF0A or the ISO-BMFF "JXL "
  box) instead of trusting finfo — keeps the strict guarantee on every
  libmagic version. A .jxl file whose bytes aren't JXL is still rejected.

Also harden ProtectedMediaStorage deletions: route all 7 unlink() sites
through a new confinedUnlink() that realpath-confines the target to the
public/media or storage/protected-media root (defence-in-depth on top of
mediaBasename()'s filename whitelist).

Adds a JPEG-XL serving test (valid jxl → 200 image/jxl; spoofed bytes →
403) to MediaAccessSecurityTest.

Subject: [PATCH 08/11] feat(imaging): generate JPEG-XL via cjxl when libvips
 lacks libjxl (#109)

JPEG-XL generation previously required a libvips build with libjxl, which
is rarer than the standalone cjxl (libjxl reference) encoder. Add a cjxl
fallback so jxl variants are actually produced on far more hosts:

- ImageEngine::capabilities()['jxl_write'] is now true when libvips can
  write jxl OR (Imagick is present AND cjxl is on PATH).
- ImageEngine::encode() routes jxl to a new encodeJxlViaCjxl() when vips
  is absent or its build can't write jxl: Imagick produces the resized,
  metadata-stripped PNG intermediate, cjxl transcodes it to .jxl (argv
  proc_open, no shell).
- ImagesGenerateCommand derives jxl variant dimensions from the source
  aspect ratio (getimagesize() can't read .jxl, which would otherwise
  store height=0).

Verified end-to-end on a cjxl host: images:generate now emits real .jxl
variants (FF0A codestream, correct dims), MediaController serves them as
image/jxl, and NSFW/password albums quarantine them to protected-media.
Adds ImageEngineJxlTest (skips where no jxl encoder exists).

 (F016/F017/F018/F029)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Comment/message-only, no logic change:
- F017: resizeWithImagick() comment described an inline Imagick body
  "below" that no longer exists after the F003 refactor — it now
  delegates to resizeWithImagickOnly(). Reworded to match.
- F018: $allowed comment said "variants are jpg/webp/avif as usual";
  jxl is now a real generated+served variant — updated to include it.
- F029: the HEIC-unsupported RuntimeException leaked which imaging
  libraries are present ("no libheif / Imagick HEIC delegate") in the
  client JSON response. The client now gets a generic message; the
  detail is logged server-side via Logger::warning. Acceptance logic
  unchanged.
- F016: strengthened the nosemgrep rationale on ImageEngine::run() —
  it's private static and every caller passes a constant binary name
  plus an app-controlled path, so a future user-influenced argv would
  be caught in review.

Subject: [PATCH 10/11] test: reusable coverage for the #109 image-pipeline
 changes

Adds 23 reusable, capability-guarded tests over the changed surface
(skip cleanly where libvips/cjxl/GD are absent so CI stays portable):

- ImageEngineTest (10): capabilities() contract + caching, jxl_write /
  heif_read backing-encoder consistency, encode() fast-path/fallback
  contract, JPEG-XL-via-cjxl encode (valid signature, no upscale,
  degenerate-input clamping), dimensions() vips/no-vips contract.
- MediaControllerMediaTypeTest (9): JPEG/JPEG-XL served with correct
  MIME, ISO-BMFF + codestream JXL signatures accepted, spoofed /
  truncated / empty .jxl rejected by the strict magic-byte gate,
  unknown extension never resolves, public jxl cacheable, protected
  jxl quarantined + no-store.
- ProtectedMediaStorageTest (+4): .jxl basename resolves and
  quarantines for protected albums / stays public for public ones,
  confinedUnlink removes jxl inside the media roots, and traversal
  dbPaths never resolve or delete.

Together with this branch's MediaAccessSecurityTest (5), ImageEngineJxl
Test (1) and the MigrationsTest jxl coverage, the changed code is
locked in against regression.

Subject: [PATCH 11/11] docs(readme): document the modern image pipeline (#109)

Cover the capability-detected engine (libvips fast path + Imagick/GD
fallback), HEIC/HEIF import for iPhone photos, and opt-in JPEG-XL
generation+serving (libvips+libjxl or cjxl): variant tree, quality
table, format/HEIC settings, and the headline feature line.
