The TipTap + Yjs + Hocuspocus stack works in dev. Before declaring Echodo daily-usable, verify two browsers on the deployed collab service can edit the same document without drift, disconnect, or auth issues.
## Description
This is a verification task, not a feature task. It has two parts: build a checklist, run the checklist, document the result.
### Pre-flight
- Deploy must be up. CT 102 (Postgres/Redis), CT 107 (Coolify web), collab service running and reachable.
- A test workspace must exist with at least one document object.
- Two browsers with different sign-ins (use credentials provider for both — fastest path).
### Checklist
1. Browser A opens the document. Verify cursor appears and TipTap loads.
2. Browser B opens the same document. Verify B sees A's content.
3. A types a paragraph. B should see it within ~200ms.
4. B types in a different paragraph simultaneously. Both should converge without lost characters.
5. A goes offline (devtools network → offline), types, comes back online. Yjs should reconcile A's offline edits.
6. Kill the Hocuspocus process; clients should reconnect when it comes back (verify in `apps/collab-server/src/index.ts` logs).
7. Close both browsers. Reopen. Verify content persisted in Postgres (Hocuspocus database extension).
### Output
Write the result up as a comment block in `apps/collab-server/README.md` (create if missing) — a one-screen "verified on $DATE against $COMMIT_SHA, here's what works" note. Future operators need to know whether this stack is trusted or risky.
### If you find a regression
Don't fix it in this task. File a follow-up task in the same epic and flag the issue clearly. This task is verification; fixes are scoped separately so the verification has a clean before/after.
## Subtasks
- [ ] Verify deploy is live on CT 107 with collab server reachable.
- [ ] Run the 7-step checklist above.
- [ ] Write the result block in `apps/collab-server/README.md`.
- [ ] File any regression follow-ups as new tasks under this epic.
The pieces an agent can verify without a live deploy + two browsers were checked as Path A landed:
-`pnpm lint && pnpm type-check` is green across all 6 packages, including `@tasks/collab-server`. `apps/collab-server/tsconfig.json` was cleaned up in commit `1c9deea` (removed vestigial `rootDir`/`declaration`/`outDir`/etc.).
- The auth changes that landed in commit `875b1cf` (Authentik SSO, case-insensitive emails, first-signin workspace provisioning) and subsequent Path-A commits do **not** touch the Hocuspocus auth path in `apps/collab-server/src/index.ts`. The session model the collab server reads from is unchanged.
- Workspace home, AI chat, and landing-route changes are all confined to `apps/web` and don't import or affect anything under `apps/collab-server`.
So the static health is fine. What's left is the live multi-browser test against the deployed stack, which has to be driven by an operator with the homelab credentials and two browser sessions in hand.
