- Removed the `vimeo/psalm` dependency and all related files
(`psalm.xml`, `psalm‑baseline.xml`, suppress annotations).
- Added **PHPStan** (v2.1.54) and **PHP‑CS‑Fixer** (v3.95.1) to
`vendor/bin/`.
- Created `phpstan.neon` (level 5, bootstraps `app/bootstrap.php`,
scans `Parsedown.php`).
- Created `phpstan‑baseline.neon` with 10 pre‑existing errors.
- Added `.php‑cs‑fixer.dist.php` (PSR‑12 + PHP80Migration, targets
`app/src` & `app/tests`).
- Added `biome.json` and updated `justfile` to replace the old Psalm
recipes with `phpstan`, `cs‑check`, and `cs‑fix`.
- Updated `.gitignore` to exclude PHPStan and PHP‑CS‑Fixer cache files.
- Updated several JS files (`file‑preview.js`, `file‑upload‑queue.js`)
eand PHP controllers (`MediaController.php`, `SearchController.php`,
`SystemController.php`).
- Minor adjustments to `TODO.md`, `app/src/Database.php`,
`app/src/Parsedown.php`, `app/src/ShareLink.php`, and
`app/src/SmtpRelay.php`.
- Live file preview on all file inputs (file-field partial, edit template):
thumbnails for images, emoji icons for PDF/video/zip/vtt, filename + size
- New file-preview.js wired via $extraJs in add.php / edit.php and direct
<script> in partage/index.php; $extraJs support added to head.php
- admin/recapitulatif.php: replace plain table with rich file list — image
thumbnails linked to media.php, type badges, human-readable size, date
- partage/recapitulatif.php: full rewrite — shows thesis metadata + files
list with same rich display (no media links for student privacy)
- form.css: new sections for .file-preview-list (live preview) and
.recap-file-list / .recap-dl / .partage-recap (recap pages)
