-# Change: Fix Fullscreen Chat Panel Scrolling
-
-## Why
-After the persistent chat panel refactoring (commits `5525813` and `d796015`), the fullscreen chat mode is no longer scrollable. When the chat panel is in fullscreen mode (`viewMode === 'chat'`), messages accumulate but users cannot scroll through them.
-
-## What Changes
-- Fix CSS flexbox chain in `LaunchView.vue` so that `overflow-y: auto` on `.chat-messages` activates correctly in fullscreen mode
-- Add `min-height: 0` to intermediate flex containers (`.chat-panel-content` and `.chat-box`) to allow them to shrink below their content size
-
-## Impact
-- Affected specs: chat-panel (new capability spec)
-- Affected code: `frontend/src/pages/LaunchView.vue` (CSS only, ~2–3 lines)

-## ADDED Requirements
-
-### Requirement: Fullscreen Chat Scrolling
-The chat messages area SHALL be scrollable when the chat panel is in fullscreen mode and messages exceed the visible viewport height.
-
-#### Scenario: Messages overflow in fullscreen chat
-- **WHEN** the chat panel is in fullscreen mode (`viewMode === 'chat'`)
-- **AND** the number of chat messages exceeds the visible area
-- **THEN** the `.chat-messages` container SHALL allow vertical scrolling via `overflow-y: auto`
-
-#### Scenario: Scroll position preserved on new message
-- **WHEN** the user is scrolled to the bottom of the chat
-- **AND** a new message arrives
-- **THEN** the chat SHALL auto-scroll to show the latest message

-## 1. Implementation
-- [x] 1.1 Add `min-height: 0` to `.chat-panel-content` in `LaunchView.vue`
-- [x] 1.2 Add `min-height: 0` to `.chat-box` in `LaunchView.vue`
-
-## 2. Verification
-- [x] 2.1 Run `openspec validate fix-fullscreen-chat-scroll --strict --no-interactive`
-- [ ] 2.2 Manual visual test: open app, verify fullscreen chat scrolls when messages overflow
