+## Rejection Notes
+
+**2026-03-16:** Previous coder produced zero code changes — feature branch had no diff against master. The coder must actually use `git bisect` to find the breaking commit and produce a surgical fix. Do not submit with no code changes.

+# Bug 245: Chat history persistence lost on page refresh (story 145 regression)
+
+## Description
+
+Story 145 implemented localStorage persistence for chat history across page reloads. This is no longer working — refreshing the page loses all conversation context. This is a regression of the feature delivered in story 145.
+
+## How to Reproduce
+
+1. Open the web UI and have a conversation with the agent
+2. Refresh the page (F5 or Cmd+R)
+
+## Actual Result
+
+Chat history is gone after refresh — the UI shows a blank conversation.
+
+## Expected Result
+
+Chat history is restored from localStorage on page load, as implemented in story 145.
+
+## Acceptance Criteria
+
+- [ ] Chat messages survive a full page refresh
+- [ ] Chat messages are restored from localStorage on component mount
+- [ ] Behaviour matches the original acceptance criteria from story 145
+
+## Investigation Notes
+
+**Use `git bisect` to find the commit that broke this.** Story 145 delivered working localStorage persistence — something after that regressed it. Find the breaking commit, understand the root cause, and fix it there. Do NOT layer on a new implementation. Revert or surgically fix the regression.
