Maths Web keeps current-tab context, TEACH recovers bounded current-tab drafts, BSL Options dismisses predictably, Anchor clearly distinguishes Any age from Open Studio, and Scaffold passes relevant context to the intact Writing Specialist only when no unfinished writing draft exists. Touch text-entry sizing was corrected without changing desktop hierarchy."

Its assets, manifest and service worker are scoped to /routine/; source maps and source-only release evidence are not deployed."

All application logic, content, controls, routes and storage contracts remain intact."

Ambiguous actor, object, direction, state and destination cues were repaired without changing the twelve routines or sixty-six steps. Manual remains the default; teachers may opt into Automatic, choose a separate 5-second-to-10-minute duration for each step, pause or resume the countdown, and still move manually. Existing IndexedDB keys, imports, exports, print, practice, audio and navigation are preserved."

Menus remain independently open through selections and close only through the same trigger or their own close control. Local persistence, editable output, copy, text download, print and scoped offline support remain available."

Its quiet board remains loaded while a specialist application is in front."

Provider, non-ink canvas, sanitised styled SVG and bounded pupil-facing text fallbacks serve appropriate specialist apps; TEACH remains private by default."
