 - 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.
 - 2026-10-14 · **Scouting is plural.** Time's trending-repos scout stays the first source; notplanned's curated backlog is a second source into the same pitch round; more sources can be added the same way. notplanned is not "the" scout. Why: popularity and wanted-but-unbuilt are different signals, and the loop should be able to take several.
 - 2026-10-14 · **The old Fly edge is down; its sites are dark on purpose.** `teahub-gitea` scaled to zero (app kept, no machines). Dark until ported: persimmons.app, phast.app, phly.cloud, yolopreneur.lol apex/www, supertestnet.lol, notplanned., maths., 🫖, matcha.teahub.xyz. Per-venture `<slug>.yolopreneur.lol` Workers are unaffected. The Mac is now reachable only over the tailnet; the last public wire into it is cut. Port order: persimmons, phast, yolopreneur apex. Why: the edge was the only thing coupling public DNS to the Mac, and nothing behind it had meaningful traffic.
+- 2026-10-14 · **Time moves to prod. GitHub was the proof of concept.** Supersedes the "GitHub is upstream for Time" clause above and the "merge into Time on GitHub" entry: the factory runs on prod Gitea, in one place, with Gitea Actions. `teahubxyz/time` on GitHub becomes read-only once the port lands; no two-way issue sync, ever (Time's state is its issue comments, and a mirrored state machine is a conflict generator). Steps: Fly runner → Gitea backend behind Time's forge module → migrate `time` with issues once → flip workflows to `.gitea/workflows` → archive GitHub copy. Why: Time in one repo host and Teahub in another made no sense; everything on GitHub would defeat standing up Gitea at all.
+- 2026-10-14 · **Runner on Fly: `green-tea-runner`** (act_runner 5.0.0-dind, iad, shared-cpu-2x/4GB, 10GB volume holding Docker's data root — Fly's rootfs is overlay so `/var/lib/docker` must live on the volume). Labels `ubuntu-latest`, `ubuntu-22.04` → `node:22-bookworm`. Registered instance-wide as `fly-iad-1`. Smoke: `teahubxyz/teahub` `.gitea/workflows/smoke.yml` green. Why: Actions on prod are a precondition for Time on prod.
