  ## Unreleased
  
++- **The forum's links follow Community's move to `/forum`** (design 2026-11-07): Space's forum redirect now
++  maps `/s` and `/s/*` straight to `/forum` and `/forum/<space>/<thread>` (the `/t/` segment is gone) instead
++  of passing the old path on, so a bookmark lands in one hop. The home page, both navbars and `llms.txt` link
++  `https://openvibe.community/forum`; the forum API paths still answer 308 unchanged.
  - **Official example spaces** (plan §4 Space: "Next: official example spaces"): three published examples owned by the official OpenVibe account — a link page (`ov-links`), a portfolio (`ov-portfolio`) and a monthly community night with a live RSVP list (`ov-night`) — adapted from the Space kit's `site-links`, `site-portfolio` and `site-event` templates and kept in `seeds/official-spaces/`. `node scripts/seed-official-spaces.js` creates and publishes them through the service's own modules (`server/spaces/official.js`); it is idempotent, `--revise` repairs drift, and a slug somebody else holds is reported and never taken. `spaces.create` now accepts an explicit `slug` (same checks as a generated one). `test/official-spaces.test.js`.
  - **Share:** a space's page carries the network's one Share button (`data-ov-share-sheet`) in its actions; it shares the published space's own address (or the page's address for a draft), with its name and description. `test/spaces.test.js`.
  - **Guest drafts** (openvibe.website, plan 5.9: "making websites and code without needing OpenVibe logins"): a visitor who is not signed in makes a draft on openvibe.space (`GET/POST /spaces/guest`) from a website template or a sentence, and edits it with a secret link (`/spaces/<id>/edit?key=…`; the cookie only remembers it, the link alone works). The draft has no owner and of the secret only its sha256 is kept. It is static: never published, no visitor's data, no server functions; in the preview the SDK answers "sign in to use this" where a visitor's account would be needed. A signed-in person who holds the secret claims it (`POST /spaces/<id>/claim`): it becomes theirs, the secret is cleared, and `space.app.claimed` is logged. The limits (per address, per draft, per service) and the seven-day expiry are in `server/hosting-config.js`; the abuse screen (`server/spaces/content-check.js`) refuses a phishing page and any form in a guest draft that posts to another origin.
