vh
70b7281182
Prime, 2026-10-09: "vh gets albok-everything". playbooks/nh3-albok-vh-viewer.yaml joins vh to albok-read, albok-personal and albok-feedback on nh3-albok and authorizes his four Macs' public keys for vh; verified at a fresh login that every wing's .browse/ lists and reads. The withdrawal harness gains a macOS driver (run-mac.sh: every mountable FUSE backend, a read-only smoke of the real wings, results copied back), env overrides for a non-container client, and summarize.py. Sanity-checked as vh from the Linux container before staging.

"""Build a replica of an albok browse view on the share host (nh3-albok).
|
|
|
|
Run ON the server as infra-ops, no sudo:
|
|
ssh infra-ops@10.100.50.44 python3 - < setup-replica.py > manifest.json
|
|
|
|
Why a replica and not the live view: the test renames `.browse/` away. On a live
|
|
wing that rename races albok-service's own link()/unlink() calls, and a failed
|
|
mandatory unlink withholds the wing (BROWSE_WITHHELD marker + a failed write
|
|
transaction). The replica has the same shape as the real view
|
|
(`<wing>/.browse/<locator>` -> relative symlink `../../<id[:2]>/<id>/<blob>`), sits
|
|
on the same filesystem (root ext4), and is served by the same sftp-server, which
|
|
is what the withdrawal property depends on.
|
|
|
|
Content is deterministic per object, so the client can verify bytes without
|
|
fetching a reference copy.
