When haproxy -c fails, parse ALERT line numbers, map to service domains via # service: comments in generated config, exclude broken services, and regenerate. One retry — prevents a single bad registration from blocking all config updates.

TODO
Response headers don't work with host ACL conditions
http-response set-header ... if host_X doesn't work because hdr(host) is a request-phase fetch that HAProxy can't evaluate in the response phase. The headers are generated but silently ignored (HAProxy logs a WARNING).
Fix: capture the host in a transaction variable during the request phase, then use it in response rules:
http-request set-var(txn.host) hdr(host)
acl is_keila var(txn.host) -i keila.cloud.payne.io
http-response set-header Access-Control-Allow-Origin "https://cloud.payne.io" if is_keila
Affects: keila (CORS headers), plausible (Private-Network-Access header).
Input validation for header values
Header values with special characters (newlines, NULs) should be rejected at registration time. Currently values are Go-%q-quoted in the HAProxy output which handles spaces/commas but may produce backslash escapes that HAProxy doesn't understand for edge cases.
