 - 2026-10-14 · **Mac runners reversed.** Last week's move of runners onto hb-5 is undone on purpose (portability exercise).
 - 2026-10-14 · **Venture loop on teahubxyz/time paused** until the audit's remaining items are judged safe (3 criticals + 3 highs fixed in time#45, #46).
 - 2026-10-14 · **well-known.online is a separate product**, not a Teahub component; may later be prod's signup front door. No dependency either way.
+- 2026-10-14 · **The Mac's Gitea stays, as a separate unit.** The operator keeps a Gitea on hb-5 to play with customisation. It is not connected to prod: no mirrors, no shared users, no shared tokens, no DNS under teahub.xyz pointing at it beyond the archive hostname matcha.teahub.xyz (which may go). Why: Teahub and the Mac are distinct units; the Mac's job is maths and experiments, prod's job is being prod.
+- 2026-10-14 · **Graduated ventures are orgs on prod** (persimmons, phast, phly …), treated as independent clients of Teahub with their own repos and a pages convention. Not wholesale imports; each starts from what it actually is. Why: a venture with its own domain is a client, not a folder of the factory.
+- 2026-10-14 · **notplanned + venture pages merge into Time's venture loop on GitHub**, not into prod Gitea. Why: Time already is the venture loop; two listings would drift.
