chore(hub): re-bake python-numpy as a portable pack (rootfs sidecar)#248
Merged
Conversation
…#242 follow-up The hub-python-numpy-v1 release now carries a portable pack: re-baked with a current forkd so snapshot.json records the rootfs, re-packed (emits the content-addressed sidecar), and both assets uploaded to the release: - python-numpy.forkd-snapshot.tar.zst (15.5 MiB, new sha) - f4ae4fc74992a9eb.rootfs.zst (48.3 MiB sidecar, zstd -19) registry.json's python-numpy latest+v1 sha256/size updated to the new pack. Pull derives the sidecar URL as the pack's sibling, so no registry schema change is needed. Verified end-to-end on a clean host (privileged container, no prior forkd state): `forkd pull` the release URL → pack downloaded → rootfs sidecar auto-fetched + placed at /var/cache/forkd/python-3-12-slim.ext4 → `forkd fork -n 2` → 2/2 children alive in 107 ms. Before #242 this pull-then-fork died with FC's "Block: backing file: No such file". Other hub assets (langgraph-react, coding-agent-fork, postgres-fixture, playwright-browser, nodejs, jupyter-kernel, e2b-codeinterpreter, coding-agent) still need the same re-bake + re-pack + dual-upload to become portable — tracked as remaining ops work.

…ixture as portable packs (#249) #242 follow-up — 4 more hub assets made restorable off the packing host. Each re-baked with a current forkd (snapshot.json records the rootfs), re-packed (content-addressed rootfs sidecar), and both assets uploaded to their release: nodejs pack 10.4 MiB + sidecar 51.7 MiB langgraph-react pack 14.5 MiB + sidecar 42.5 MiB coding-agent pack 15.1 MiB + sidecar (gh/ruff/black/mypy/pytest) postgres-fixture pack 37.8 MiB + sidecar 116.2 MiB registry.json latest+v1 sha256/size updated for all four. Pull derives the sidecar URL as the pack's sibling — no schema change. Together with python-numpy (#248), 5 of 9 hub assets are now portable. Remaining: jupyter-kernel + playwright-browser (multi-GB base images), e2b-codeinterpreter (exotic base), coding-agent-fork (no build.sh — needs its workspace state reconstructed). Tracked as ongoing ops. Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

#242 follow-up (ops). Makes the first hub asset actually restorable off the packing host.

The other 8 hub assets (langgraph-react, coding-agent-fork, postgres-fixture, playwright-browser, nodejs, jupyter-kernel, e2b-codeinterpreter, coding-agent) still need the same re-bake + re-pack + dual-upload. Heavier ones (playwright browser, postgres) need their recipe-specific warmup state reproduced.
