Ubuntu 26.04 base (ffmpeg 8, ImageMagick 7), Valkey 9, Postgres 18 (v2.7.0) (#68)

* Ubuntu 26.04 base (ffmpeg 8, ImageMagick 7), Valkey 9, Postgres 18 (v2.7.0)

Fixes #67.

Base image moves to ubuntu:26.04: FFmpeg 6.1.1 -> 8.0.1 and ImageMagick
6.9 -> 7.1.2. The app pins Python 3.12 via deadsnakes in a dedicated venv
(26.04 ships 3.14, which psycopg2-binary has no wheels for). The image
checker invokes magick with a convert fallback, the temporal-outlier probe
uses pts_time (pkt_pts_time was removed in newer FFmpeg and silently
disabled that signal), and kernel header packages are purged from the
final image, clearing the unfixable linux-libc-dev CVE tail.

Also fixed: the benign ImageMagick warning gates checked for
"@warning/png.c" but ImageMagick (6 and 7) emits "@ warning/png.c" with a
space, so the benign-classification paths were unreachable; same token
fixed in tools/fix_imagemagick_profile_warnings.py.

docker-compose defaults change to postgres:18-alpine (BREAKING for
existing volumes; the 18+ images also moved the volume mount from
/var/lib/postgresql/data to /var/lib/postgresql) and valkey/valkey:9-alpine
(drop-in; service name and URLs unchanged). A tested 15->18 dump/restore
migration guide is in docs/DOCKER_SETUP.md.

CI gains an image-integration job that builds the Docker image and runs
the real-media parser tests inside it, since the ffmpeg/ImageMagick stderr
parsers fail soft and only break observably against the shipped binaries.

Verified: real-media suite passes inside the new image (10/10, including
corruption detection on ffmpeg 8 / IM7); fresh compose stack on
postgres 18 + valkey 9 scanned 5 samples end-to-end and flagged exactly
the 2 planted corrupt files; 15->18 dump/restore dry-run row counts match;
host suite 475 passed.

* Link migration guide from README docs index; changelog date

* Docs accuracy audit + stop media playback when viewer closes

Media viewer fix: closing the player modal only hid it, so a playing
video or audio file kept playing (and buffering) in the background.
closeModal() now pauses any media in the modal and detaches its sources;
the viewer close button and outside-click both route through it.
Verified in-browser: play, close, playback stops and sources detach for
both video and audio.

Docs audit: every doc was checked against the codebase by parallel
auditors and corrected. Highlights:
- docs/api/README.md and docs/examples/* documented endpoints that never
  existed (/api/scan-all, /api/stats/summary, /api/scan/parallel-v2*,
  /api/export/csv, /api/cleanup) and omitted authentication; all examples
  now call real endpoints with Bearer tokens.
- DOCKER_SETUP.md's example compose would not have booted (celery_app
  module, /health healthcheck, missing SECRET_KEY, allkeys-lru eviction);
  it now mirrors the real docker-compose.yml.
- CONFIGURATION.md/INSTALLATION.md described a Celery beat and a
  four-queue layout that do not exist; replaced with the real APScheduler
  jobs and the single pixelprobe queue. CELERY_WORKERS (read nowhere)
  corrected to CELERY_CONCURRENCY everywhere.
- PERFORMANCE_TUNING.md rewritten: its entire env-var surface
  (MAX_SCAN_WORKERS, BATCH_COMMIT_SIZE, ...) never existed in this code.
- Pool sizes (5+10, not 20+40), session lifetime (24h, not 30 days),
  task lists, adaptive chunk tiers, stuck-scan thresholds, module/model
  inventories all corrected against source.
- openapi.yaml: removed duplicate /configurations path key and the
  nonexistent DELETE /configurations/{id}; schedule scan_type enum now
  includes file_changes and orphan; export formats csv/json/pdf only.
- Removed a hardcoded deployment hostname from FIX_INCOMPLETE_SCANS.md.

* Humanizer pass across all documentation

Full-file pass over every doc (README, docs/, docs/api, docs/developer,
docs/examples, docs/maintenance) removing AI-writing patterns while
leaving audited technical facts untouched: significance inflation and
promotional adjectives cut, "What it does / Why needed" bullet walls
rewritten as prose, boilerplate best-practices lists reduced to their
concrete items, duplicate link indexes and say-nothing intros removed,
Unicode arrows in prose replaced with ASCII. Also removed two dead links
into the gitignored docs/development/ directory and fixed list numbering
in TOOLS_AND_SCRIPTS.md. Net 96 lines shorter.

CHANGELOG.MD

@@ -5,6 +5,28 @@ All notable changes to this project will be documented in this file.
 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0).
 
+## [2.7.0] - 2026-07-16
+
+### Breaking
+
+- **docker-compose.yml now defaults to PostgreSQL 18 (#67).** PostgreSQL data directories are not portable across major versions: an existing `postgres_data` volume created by PostgreSQL 15 will not start on the 18 image. Follow the new migration guide in docs/DOCKER_SETUP.md (dump on 15, restore into 18, refresh collation) BEFORE pulling the new compose file, or pin `postgres:15-alpine` to stay. The application itself works with PostgreSQL 15 through 18, so only the compose default is breaking - existing deployments that manage their own database are unaffected until they choose to migrate.
+
+### Changed
+
+- **Base image upgraded to Ubuntu 26.04 (#67).** FFmpeg 6.1.1 becomes 8.0.1 (faster demuxing/probing) and ImageMagick 6.9 becomes 7.1.2. The app pins Python 3.12 via deadsnakes and runs from a dedicated virtualenv (Ubuntu 26.04 ships 3.14, which psycopg2-binary has no wheels for yet). The image checker now invokes `magick` when available, falling back to `convert` on ImageMagick 6 systems, and the temporal-outlier probe uses `pts_time` (its `pkt_pts_time` field was removed in newer FFmpeg, which silently disabled that signal). Kernel header packages are purged from the final image, clearing the long tail of unfixable linux-libc-dev CVEs from scans.
+- **Task broker image switched from Redis 7 to Valkey 9 (#67).** Drop-in replacement: the compose service name, all redis:// URLs, and the wire protocol are unchanged, and the Valkey image ships redis-* compatibility symlinks. Valkey stays open source (BSD) while Redis moved away from it after 7.2.
+
+### Fixed
+
+- **Closing the media viewer now actually stops playback.** The viewer modal was only hidden on close, so a playing video or audio file kept playing (and buffering) in the background. Closing now pauses the player and detaches its sources.
+- **Documentation accuracy audit.** All docs were checked against the codebase and corrected: removed endpoints that never existed (`/api/scan-all`, `/api/stats/summary`, `/api/scan/parallel-v2*`, `/api/export/csv`, `/api/cleanup`), fixed the example compose file (broken celery command, wrong healthcheck path, missing SECRET_KEY, fictional CELERY_WORKERS/REDIS_HOST vars), replaced the nonexistent Celery beat with the real APScheduler jobs, corrected pool sizes, session lifetime, task lists, chunking behavior, and rewrote PERFORMANCE_TUNING.md around env vars that actually exist. Example API clients now authenticate and call real endpoints. openapi.yaml: removed a duplicate path key and a nonexistent DELETE route, completed the schedule scan_type enum.
+- **Benign ImageMagick warning classification never matched.** The gates that classify PNG chunk and profile warnings as non-corruption checked for `@warning/png.c`, but ImageMagick (6 and 7 alike) emits `@ warning/png.c` with a space - so the benign-warning paths were unreachable and such files fell through to the generic error-keyword check. Verified against real ImageMagick output on both versions.
+
+### Added
+
+- **CI now builds the Docker image and runs the real-media parser tests inside it.** The FFmpeg/ImageMagick stderr parsers fail soft (a format change yields zero detections rather than an error), so unit tests on the runner's own tool versions cannot catch a base-image regression. The new job exercises corruption detection against the exact ffmpeg 8 / ImageMagick 7 binaries that ship in the image.
+- **PostgreSQL 15 to 18 migration guide** in docs/DOCKER_SETUP.md, including volume backup, restore verification, and collation refresh.
