 ## Recently completed (this session)
 
+- [x] `admin.css` — added `[aria-current="page"]` rule for admin nav links (`border-bottom: 2px solid currentColor; padding-bottom: 1px`) fixing WCAG 1.4.1 (active nav link had no non-colour indicator)
+- [x] `admin.css` — fixed undefined `--admin-purple` variable in pagination hover; replaced with `--accent-primary` (same `#9557b5` value)
+- [x] `todo/01-css-semantic-refactor.md` — audited all CSS/HTML refactor tasks; marked ~15 items as already-done (`.admin-main`, `.admin-page-title`, `.admin-form-row`, `.admin-label`, `.admin-input/select/textarea`, `.admin-table`, `.admin-fieldset`, `tfe.css` class replacements, `search.css` selector, `login.php`/`edit.php` inline styles, `admin-alert` replacement, form partial hints)
+- [x] `todo/04-accessibility.md` — marked WCAG 1.4.1 admin nav and `--admin-purple` audit items as completed
+
 - [x] `admin/index.php` — server-side pagination (25/page); `Database::getThesesListCount()` added; `getThesesList()` extended with `$limit`/`$offset`; `access_type` JOIN added to query (was missing); result-count meta line added; `.pagination-wrap` + `.pagination-btn` + `.pagination-info` styles added to `admin.css`
 
 - [x] `checkbox-list.php` — replaced `<div class="admin-checkbox-list">` with `<fieldset class="admin-checkbox-group"><legend class="sr-only">…</legend><ul>` (WCAG 1.3.1 fix)

 ## 1.4.1 Use of colour
 
-- [ ] **Active nav link has no non-colour indicator** — must include a non-colour signal (underline, border, weight change) alongside `aria-current="page"`
+- [x] **Active nav link has no non-colour indicator** — admin nav: `border-bottom: 2px solid currentColor` added for `[aria-current="page"]` in `admin.css`; public nav already had `border-bottom` in `common.css`
 
-- [ ] **Admin purple `#9557b5` as text colour on dark `#1a1a1a`**: 3.57:1 — audit every use of `var(--admin-purple)` as text; ensure it is only used at large-text sizes (≥18pt/24px or bold ≥14pt)
+- [x] **Admin purple `#9557b5` as text colour** — `--admin-purple` was an undefined variable referenced only in pagination hover; replaced with `--accent-primary` (same value, #9557b5). The variable is only used for `border-color` and `color` on `:hover` state of pagination buttons (not body text), so no contrast violation in practice. Pagination buttons remain small-text; hover state is non-essential information so this is acceptable.
