errcheck flagged two unchecked fmt.Fprintf return values in internal/webhook/webhook.go, failing CI (run 310/311) for the whole 'trigger brain-sync on Gitea push' feature -- so no new ingestion image was ever built, and the deployed image predates this feature entirely even though infra's manifest (secret, RBAC, env wiring) was already live. Both writes are best-effort informational text after WriteHeader has already committed the status code -- a failed write here only happens on client disconnect and nothing depends on it succeeding, so explicitly discard (_, _ =) rather than log-and-continue noise.
