SQLite performance (Database::__construct):
- PRAGMA journal_mode = WAL: eliminates full-DB read locks on write, safe
for concurrent PHP-FPM workers
- PRAGMA synchronous = NORMAL: durable on commit without full fsync per write
- PRAGMA cache_size = -8000: ~8 MB page cache per connection
Accessibility foundation (WCAG 2.1 AA):
- common.css: add .sr-only utility, .skip-link (hidden until focused),
global :focus-visible (2px purple outline, 2px offset),
prefers-reduced-motion guard; remove bare outline:none from
.site-search__input
- admin.css: same :focus-visible, skip-link, and motion guard scoped to
admin purple; remove outline:none from .admin-input/.admin-select/
.admin-textarea and .admin-filters select (both had :focus border rules
already, so focus is still visually communicated)
- search.css: remove outline:none from .search-filter-select (already has
:focus border-color rule)
- All 5 public pages (index, search, tfe, apropos, licence): add
<a href="#main-content" class="skip-link"> as first child of <body>;
add id="main-content" to <main>
- templates/admin/head.php: same skip link; aria-label="Navigation admin"
on <nav>; id="main-content" on all 10 admin <main> elements
All 4 test suites pass (unit, integration, security, rate-limit).
Add a 'nginx — config' tab to the Système admin page (system.php).
- Reads /etc/nginx/sites-available/posterg (live deployed config) first;
falls back to nginx/posterg.conf (local reference copy) when the live
path is inaccessible (e.g. in dev, or wrong permissions).
- Displays a colour-coded badge: green '● Config déployée' for live,
amber '⚠ Référence locale' for the fallback.
- Renders the full config in the shared .log-output code block with
line numbers (data-n gutter via CSS ::before) and lightweight nginx
syntax colouring (comments grey, block keywords purple, directives blue).
- Reuses the existing copy-to-clipboard button.
- Tab routing: activeTab validation extended to accept 'nginx_config';
log pre-loading guards skip when activeTab is 'nginx_config'.
- No remote execution: read-only, zero new attack surface.
Replace the separate /admin/status.php and /admin/logs.php pages with a
single /admin/system.php page organised around a tab bar.
- system.php — top-level tab bar: 'Statut' + one tab per log file
(nginx accès, nginx erreurs, PHP-FPM). Switching tabs is a plain
href (?tab=…) so no JS required for navigation; the lines-selector
SELECT triggers a location change on 'change' for instant reload
without a submit button.
- Status tab preserves all existing service cards, PHP runtime grid,
and disk-usage bar from the old status.php.
- Log tabs preserve line-count selector, file metadata bar, and
per-line colour coding from the old logs.php.
- New: copy-to-clipboard button on each log output block (Clipboard
API with textarea execCommand fallback).
- status.php / logs.php replaced with 301 redirect stubs so existing
bookmarks and links keep working.
- templates/admin/head.php: 'Statut' + 'Journaux' nav items replaced
with a single 'Système' item; active state covers all three page
names for redirect compatibility.
