+# Phase 17 Plan 01: Chat Discussion View — Message Bubble Restyle Summary
+
+**One-liner:** Own-vs-others chat bubbles with brand-tint right-alignment using .ui-card surface and new .message-* CSS classes driven by a static view model.
+
+## What Was Built
+
+- **CSS message classes** appended to `app.css` after line 1897: `.message-row`, `.message-own`, `.message-other`, `.message-bubble`, `.message-own .message-bubble` (brand tint rgba), `.message-other .message-bubble`, `.message-meta`, `.message-own .message-meta`, `.message-meta .message-author` — all using `var(--...)` design tokens only (exception: rgba tint value spelled out intentionally per plan)
+- **discussion_view.go**: `DiscussionMessageView` struct (Author, Timestamp, Body, IsOwn bool), `DiscussionTabData` struct, `NewDiscussionTabData()` factory returning 4 alternating demo messages
+- **discussion_view_test.go**: `TestChatMainContentRendersBubbleClasses` — asserts `.ui-card`, `message-own`, `message-other`, `message-bubble` classes present in rendered HTML
+- **dashboard_components.templ**: `ChatMainContent()` stub replaced with `ChatMainContent(data DiscussionTabData)` — renders `.ui-card` container, empty state via `@ui.EmptyState`, message rows with `.message-row message-own/other`, `.message-meta`, `.message-bubble`
+- **auth.go**: `GetChatPage` updated to pass `views.NewDiscussionTabData()` to `views.ChatMainContent()`
+
+## TDD Gate Compliance
+
+- RED commit `dd1133d`: test + view model + CSS (compile error confirmed — ChatMainContent zero-arg)
+- GREEN commit `81ccaeb`: templ component + handler wiring (TestChat passes, full suite passes)
+
+## Verification
+
+```
+go test ./internal/web/views/ -run TestChat -count=1  → PASS
+go test ./... -count=1                                → all 6 test packages pass
+go build ./...                                        → exits 0
+```
+
+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+## Deferred
+
+- D-D01 through D-D04 deferred per `<scope_note>` in plan: no `DiscussionMessagesFromRows`, no `currentUserID` threading, no SSE/HTMX IsOwn mutation — all require real backend infrastructure not present in this phase.
+
+## Known Stubs
+
+- `NewDiscussionTabData()` returns hardcoded demo messages — intentional per plan. Real data wiring deferred to the phase when the discussion backend is built. Demo data is sufficient for visual verification of CSS bubble classes.
+
+## Threat Flags
+
+No new threat surface introduced. All `{ expr }` interpolations in `ChatMainContent` use templ auto-escaping (Author, Timestamp, Body). T-17-01-01 mitigated. T-17-01-02 accepted (demo data only, auth unchanged).
+
+## Self-Check
+
+Files created/modified exist on disk — verified by successful `go test ./... -count=1`. Commits dd1133d and 81ccaeb confirmed in git log.
+
+## Self-Check: PASSED
