Real screenshots (Playwright, headless) from a clean demo room/users
created for this purpose and removed afterward: the main chat view
(Markdown, mentions, reactions), the custom theme builder mid-edit, the
same room under a custom theme, and a mobile-width view.

Both were thin/stale for what the project has actually grown into (the
frontend README still framed things as "Phase 1-6" and listed maybe a
third of the current src/ tree). Added a Features section and tech-stack
summary to the root README, and refreshed the frontend README's layout
listing to match what's actually in src/ today.

Renames the app's display name everywhere (page titles, PWA manifest,
TopBar, email subject lines, HMAC signature header) and its internal
technical slug from chatapp to ds-chat/ds_chat: the Python package name
and console script, the systemd unit and its user/group/paths, the deploy
scripts, the Docker container names, and the Postgres database name.
The live dev Postgres role stays "chatapp" -- renaming a role requires
disconnecting the session using it, which needed a temporary superuser
role Claude's auto-mode classifier correctly declined to create
unsupervised. Functionally invisible (it's just a login credential), but
worth knowing about if this ever needs fully cleaning up by hand.

Deployment artifacts for the two-server architecture from ARCHITECTURE.md
§9, grounded in verified Debian 13 (trixie) package facts (Python 3.13,
PostgreSQL 17, Node.js 20, redis-server 8.0, certbot 4.0, ufw --
confirmed rather than guessed) rather than a generic "modern Linux" guide:
deploy/systemd/chatapp.service, deploy/chatapp.env.example,
deploy/backup-postgres.sh, deploy/upgrade.sh, and DEPLOYMENT.md as the
actual numbered runbook.
Revised mid-implementation once the user clarified the app sits behind an
existing, separate Nginx Proxy Manager rather than local Nginx+certbot:
dropped the local Nginx config entirely, gunicorn now binds a TCP port
instead of a Unix socket, and app/main.py gained a static-file mount + SPA
fallback route so gunicorn alone serves the built frontend, /api, and /ws
on one port -- what lets NPM's simple one-upstream-per-domain mode work
with zero custom path routing. Path-traversal-guarded (full_path comes
straight from the URL) and cache-header-differentiated (far-future
immutable on Vite's content-hashed assets, no-cache on index.html/sw.js/
manifest so a deploy actually propagates instead of leaving clients on a
stale service worker) -- verified locally against a real gunicorn process
serving a real frontend build, not just eyeballed.
Two real gaps found and fixed alongside the docs, not just noted: gunicorn
wasn't a dependency anywhere despite being the whole app-server design, and
there was no WebSocket reconnect logic on the client -- a reverse proxy's
idle-connection timeout (NPM's or otherwise) would have silently killed a
quiet chat connection with nothing to recover it. Added exponential-backoff
reconnect to useChatSocket.ts, verified by hand (killed and restarted the
local dev backend mid-session, confirmed auto-reconnect and that a message
sends successfully afterward with no page reload).
Every command in DEPLOYMENT.md that could be verified locally, was: the
exact systemd ExecStart line run against local dev Postgres/Redis with
clean SIGTERM shutdown, the static-file serving behavior against a real
build, both shell scripts syntax-checked. What couldn't be verified from
this sandbox (actual Debian 13 hardware, Nginx Proxy Manager itself) is
flagged explicitly in the plan rather than claimed.

Adds room_invites table + migration, owner/admin/member role enforcement
(require_room_role), and endpoints for private room creation, room
management (update/delete/leave/transfer-ownership/change-role/remove-member),
and the invite lifecycle (create/list/accept/decline/revoke). Registration
stays invite-only via the CLI from Phase 1 — this is a separate, room-level
invite system for adding existing users to private rooms.
Frontend is untouched: the UI redesign is happening separately, so this phase
is backend + tests only (35 passing). Verified no regressions in the Phase 1
open-room/WebSocket flow via manual smoke test.

Invite-only FastAPI + SQLAlchemy(async) + Postgres backend (session-cookie
auth via CLI-provisioned accounts, open-room CRUD, single-instance /ws/chat)
and a React + Vite PWA frontend (login, room list, chat view). Backend tests
pass against a local Postgres DB. See README.md and backend/README.md for
setup, and ARCHITECTURE.md for the full phased design.
