 ## Pending
 - [x] #home-htmx-lazy-cover-images [!medium] Add htmx lazyloading on home page cover images: `revealed`-triggered cover-fragment endpoint, swap-in `<img>`, settle fade CSS, load htmx on home
 
+## In Progress
+- [x] #cleanup-toc-fix-duplicate-id [+admin] Clear TOC links after cleanup restructure. Root cause: admin-toc.js assigned `sec.id = headingId` to sections, and on rebuild-because-of-htmx-swap the section + h2 ended up sharing the same id, so getElementById returned the <section> whose textContent dragged the whole data table into the TOC label. Fix: anchor links to the heading id and never give the section that id (no duplicate ids); verified via Playwright — TOC now lists exactly Tiléversements abandonnés / Corbeille / Vidéos PeerTube with no table text.
+
+## In Progress
+- [x] #cleanup-stats-under-headings [+admin] On the cleanup page, move each section's stat/count out of the heading to a line directly under it, and merge PeerTube into a single heading. cleanup-stats-fragment: "Téléversements abandonnés" / "Corbeille" h2 now bare, stat emitted as `<p class=n-meta>` under the h2. peertube-orphans-fragment: removed the separate "Vidéos orphelines" h3; the orphan count now appears as the stat line under the static "Vidéos PeerTube" h2. Verified via Playwright: TOC still lists exactly 3 clean entries; stats render under headings.
+
+## In Progress
+- [x] #cleanup-stat-card [+admin] Render the cleanup-page section stats as a proper card box (`cleanup-stat-card`, bigger than the old inline n-meta): padded panel (bg-secondary + border, radius 10px), step-1/700/accent text. Applied to the filepond, trash and PeerTube stat lines. Verified computed style via Playwright.
+
+## In Progress
+- [x] #cleanup-desc-and-tooltips [+admin] Cleanup page: add short French descriptions under each section heading (Téléversements abandonnés / Corbeille / Vidéos PeerTube) explaining what the data is and how safe deletion is (`.cleanup-section-desc`), and native title tooltips on the Supprimer and Restaurer buttons of each row. Verified via Playwright (descriptions + tooltips render on all rows).
+
+## In Progress
+- [x] #cleanup-auto-gc-uploads [+scripts/deploy] Abandoned FilePond uploads are now garbage-collected automatically (they are risk-free staging dirs never linked to a TFE). Added `scripts/cleanup-tmp-uploads.php` (dry-run by default, mirrors the admin cleanup filepond logic: missing-session via manifest.json + 2h fallback), hourly cron `deploy/xamxam-tmp-cleanup.cron`, `just deploy-tmp-cleanup-cron` + `just deploy-check-tmp-cleanup-log`, wired into `deploy-all-first`, and documented in docs/deployment.md. Tested dry-run + --no-dry-run + active-session protection locally.
+
+## In Progress
+- [x] #cleanup-remove-filepond-section [+admin] Since abandoned FilePond uploads are GC'd by cron, removed the "Téléversements abandonnés" section from the cleanup page and the index "Nettoyer" badge now counts trash only. cleanup-stats-fragment.php renders only the Corbeille section (and "Corbeille vide" when empty); index.php badge is trash-only; admin-cleanup-bulk.js simplified to trash_files[] only. Verified via Playwright: only Corbeille + Vidéos PeerTube sections/TOC, no filepond checkboxes, tooltips intact.
+
+## In Progress
+- [x] #cleanup-page-title [+admin] Simplify cleanup page title from "Nettoyer les fichiers temporaires" to "Nettoyage" (page now mostly manages the Corbeille). Updated `app/public/admin/cleanup.php` pageTitle and `app/templates/admin/cleanup.php` h1.
+
+## In Progress
+- [x] #docs-cleanup-changes [docs] Update docs for the cleanup-page + GC changes made: admin README cleanup.php entry -> "Cleanup page (Corbeille — restore/delete trashed files)"; deployment.md adds a paragraph explaining abandoned uploads are auto-GC'd hourly and the page (titled Nettoyage) now only shows the Corbeille; added `just cleanup-tmp-uploads` recipe and documented it in development.md alongside cleanup-drafts.
+
 ## Completed
+- [x] #cleanup-toc [+admin] Add sidebar TOC to admin cleanup page; drop the "Fichiers temporaires" section level and promote "Téléversements abandonnés" / "Corbeille" from h3 to h2 top-level sections (now TOC entries). Made admin-toc.js rebuild on htmx swap/settle so async-loaded fragment sections enter the TOC.
