+# Phase 8 Context: Learning Progress View
+
+**Status:** Ready for execution
+**Started:** 2026-04-26
+
+## Goal
+
+Show evidence-backed learning progress in the web app after diagnostic
+practice.
+
+## Requirements
+
+- WEB-04: User can see learner memory, readiness, and next challenge after
+  answering.
+
+## Inputs
+
+- Phase 7 web app shell.
+- Existing backend endpoints:
+  - `GET /api/v1/learners/{userID}/memory`
+  - `GET /api/v1/learners/{userID}/readiness-map`
+  - `GET /api/v1/learners/{userID}/next-challenge`
+
+## UX Direction
+
+Keep progress in the right-side context column so the answer workspace remains
+centered. The user should see the loop close immediately: answer, feedback,
+memory, readiness, next challenge.
+
+## Out of Scope
+
+- Full graph visualization.
+- Historical readiness timeline.
+- Editing learner memory.
