+## Session: Deep-Dive Audit + Sprints 5–7 Implementation (2026-02-26)
+
+### What Was Done
+
+Ran a comprehensive second-pass audit via 3 parallel agents (submission_form Vue, template_builder Vue, settings/dashboard ERB + custom JS elements). Produced a full remediation plan saved at `.plans/refactored-forging-dream.md` covering Sprints 5–8.
+
+Then implemented Sprints 5 (Critical), 6 (High), and 7 (Medium) in a single commit.
+
+**Commit**: `cf209400` — "Implement accessibility plan: Sprints 5, 6, and 7 (WCAG 2.1 AA)"
+

+
+### Deferred: Sprint 8 (Complex — Template Builder Keyboard Access)
+
+The following items are deferred for a separate planning session due to complexity:
+
+- **8-A**: Keyboard alternative for drag-and-drop field placement (`fields.vue`, `field.vue`, `page.vue`, `area.vue`) — requires "Add to page" button + arrow-key nudging
+- **8-B**: Context menu keyboard trigger (Shift+F10) in `field_context_menu.vue`
+- **8-C**: Field settings dropdown focus trap + Escape handler in `field.vue`
+- **8-D**: Live region announcement when field added/removed in `builder.vue`
+
+### Next Session Recommendations
+
+1. **Sprint 8**: Plan and implement template builder keyboard access (items 8-A through 8-D above) — most impactful remaining gap
+2. **Manual verify Sprint 5-7**: Test search input with keyboard only; trigger flash messages; test file upload Tab flow; cycle through form progress dots with arrow keys
+3. **7-C skipped**: `v-show` + `aria-hidden` sync on `form.vue` container — double-check if added or still needed
+4. **7-H skipped**: `scroll_buttons.js` aria-hidden on hidden buttons — verify or add
+5. **7-I deeper fix**: Current fix adds `aria-label` to the native select; consider full combobox refactor for better AT experience (lower priority)
+6. **Retest audit**: Run fresh accessibility audit to confirm no regressions introduced
