A full disk made kubelet's node-pressure eviction pick control-plane pods
alongside game pods (both priority 0), and with the images existing only
in the node's containerd (air-gapped), losing the api meant a manual
image re-import. Every control-plane pod template (api/operator/reaper/
registry) now names the bundle's cluster-scoped felis-control-plane
PriorityClass: value 1,000,000, preemptionPolicy Never — eviction order
only, never preempting a running game server. The image-GC half is not
code-fixable on an air-gapped box; troubleshooting gains 13b with the
recovery path (re-run the installer to rebuild imports, or docker save |
k3s ctr images import - for one image).
6-way concurrent redeem of one code 500'd on users_username_key (each request
generated a fresh user id but the same uuid-derived username), plus the rarer
two-codes-one-uuid race. Same drift family as VerifyLinkCode, which already
locks its code row and handles the conflict.
- SELECT ... FOR UPDATE the code row: same-code racers serialise; losers exit
as ErrLinkCodeInvalid (400 invalid_code), no user row is attempted.
- INSERT users ... ON CONFLICT (username) DO NOTHING + re-read by username:
cross-code racers converge on the winner's row (role checked, staff still
refused) instead of a unique-violation 500.
- account_links ON CONFLICT (mc_uuid) DO NOTHING for the same race.
Verified live: same-code x6 = 1x200 + 5x400; two-codes x2 = 2x200 same user;
db clean; zero unmapped errors.
The interface doc promised 'each joined to its staff username', the fake and
the pending handler both project username and created_at, but the PG query
selected neither — live internal /op-login/pending returned username:"" and
created_at:0001-01-01. Same drift class as ConsumeLoginEmailOTP: fake-based
tests can't see PG-only regressions.
