-## Template Overrides
+## Fix Details
 
-Gitea supports custom template overrides by placing files in `custom/templates/`.
+### V2: 25 Form Inputs Without Labels
-The templates here override the default Gitea templates with a11y improvements.
 
-### R1: Password Visibility Toggle
+**Page:** Explore/Repositories (`/explore/repos`)  
+**Criterion:** WCAG 3.3.2 — Labels or Instructions  
+**Severity:** High  
+**Audit:** #492, Issue #546
 
-Adds an eye icon (👁) button next to the password field that toggles between
+The search field and all radio button inputs in the filter and sort dropdowns lacked programmatic label associations. This made the controls inaccessible to screen reader users.
-`type="password"` and `type="text"`. Updates `aria-label` dynamically.
 
-### R2: aria-required
+**Changes:**
 
-Adds `aria-required="true"` to the username and password inputs, which
+| Element | Input Name | Fix |
-properly communicates required state to screen readers.
+|---------|-----------|-----|
+| Search field | `q` | `aria-label` on input (via `shared/search/input.tmpl`) |
+| Clear filter | `clear-filter` | `aria-label="Clear all filters"` |

-### R3: Star/Fork aria-label
+**Files Modified:**
+- `deploy/gitea-a11y/custom/templates/shared/search/input.tmpl` (new)
+- `deploy/gitea-a11y/custom/templates/shared/repo/search.tmpl` (new)
 
-Wraps star and fork count links with `aria-label="2 stars"` so screen
+**Total inputs fixed:** 25
-readers announce the meaning, not just the number.
-
-### R4: `<time>` Elements
-
-Wraps relative timestamps ("2 minutes ago") in `<time datetime="2026-04-13T17:00:00Z">`
-providing both human-readable text and machine-readable ISO 8601 dates.
