- Fix#1: _detect_existing_project now checks .claude/settings.json for
"da sync" marker instead of deleted CLAUDE.md; update tests accordingly.
- Fix#2: preview endpoint uses autoescape=False to match /setup rendering;
align render_agent_prompt_banner in welcome_template.py to the same.
- Fix#3: apply _sanitize_banner_html to override render path in setup_page
so all render paths sanitize consistently.
- Fix#4: move .setup-link-banner into the existing-user branch where
account_details.last_sync_display is reachable; remove dead copy from
new-user branch.
- src/welcome_template.py: rewrite as HTML banner renderer
(render_agent_prompt_banner); drop _list_tables, _metrics_summary,
_marketplaces_for_user, render_welcome, _load_default_template.
build_context now exposes only instance/server/user/now/today.
_sanitize_banner_html strips script/iframe/on*/javascript: post-render.
- app/api/welcome.py: drop get_welcome handler, WelcomeResponse, old
_VALIDATION_STUB_CONTEXT. Admin endpoints stay at same URLs; validation
stub updated to match new slim context. Preview now uses autoescape=True.
- app/web/router.py: setup_page calls render_agent_prompt_banner and passes
banner_html to install.html; admin_agent_prompt_page drops _load_default_template.
- app/web/templates/install.html: add .setup-banner CSS + banner block above hero.
- cli/commands/analyst.py: replace _generate_claude_md with _init_claude_workspace;
no CLAUDE.md written, only .claude/CLAUDE.local.md placeholder + settings.json hooks.
- tests: delete test_cli_analyst_welcome.py (tests deleted endpoint/function);
rewrite TestGenerateClaudeMd → TestInitClaudeWorkspace; update api test to
assert /api/welcome returns 404 and remove welcome-fetch tests.
