- drag & drop now saves in the background (700 ms debounce) without reloading:
sections stay open, scroll position is kept; on failure it retries every 3 s,
and navigator.sendBeacon flushes unsaved changes on page leave
- removed the explicit save button (autosave only), status indicator shows
«Изменения не сохранены… / Сохранение… / Порядок сохранён»
- new global ui-state.js: restores open <details> and scroll position after any
reload/redirect within the same page (applies to all pages, not just /learn)
- auto-expand a collapsed chapter/section while hovering during drag
- identity group detail (and thus every student list) is ordered by full name;
defense rows on the group page sorted by name + lab number
- tablekit.js: click a header to sort (numeric-aware, ru locale), second click
flips direction (▲/▼ indicator); search input with data-target filters rows
by substring live
- tables wired: group matrix (with data-sort on variant cells), defense table
(data-sort on status/date), students table, lab assignment lists per group,
groups list and labs list; name/number columns pre-marked ascending
- non-sortable columns marked data-nosort (checkbox/actions)
- Dashboard: real stats (groups, students, labs, average grade), labs/groups
summary lists, no placeholder tile
- Lab page: view + edit combined — metadata form in modal, condition rendered
as markdown, per-level variant tables with add/edit/delete dialogs,
level rename/delete, student level/variant selectors with group filter
- Labs list: create-lab dialog with manual level entry (code; title lines)
- Groups: create-group dialog, add-student dialog (auto password, toast card)
- Content: public /learn reader is the single place; admin buttons (new
article with chapter/section create-or-select, rename/delete chapters and
sections, move articles between sections, import zip) appear for admins;
removed separate 'Контент' admin section
- Buttons use btn classes instead of nav-link
- Favicon: generated SVG book icon
- Security: CSRF synchronizer token interceptor (replaced spring-security in
web which broke logback under nested jars), session regenerated on login,
hardened session cookie, gateway actuator limited to health,info
- Jackson 3: nullable-safe request DTOs for labs (FAIL_ON_NULL_FOR_PRIMITIVES)
- academic: POST /labs (manual create with levels), level add/rename/delete,
content chapters/sections CRUD, article create/move/delete endpoints
- Replace all inline style= with reusable CSS classes
- Add layout classes: page, page-header, page-main, page-footer
- Fix footer at bottom via flex column + flex:1 on main
- Remove jsessionid from static resource URLs
- Create lab1-full.zip with 30 variants from PDF metodichka
- All templates use CSS var classes for light/dark theme
