CLAUDE.md rules out // line comments in committed Go. The rationale they
carried is in the commit messages for each fix; doc comments that already
existed are kept, updated where the code they describe changed.
Also replaces reflect.Ptr with reflect.Pointer and rewrites the YAML keyword
alternation as a lookup table, both flagged by golangci-lint.
informTrafficToExternalAPI posted through the package-level fasthttp.Do,
which carries no read or write deadline. Run() is scheduled @every 5s under
cron.SkipIfStillRunning, so a receiver that accepts the connection and then
neither answers nor closes did not just delay one notification — it held the
job, and every following tick was skipped for the duration.
What stops with it is more than counters: AddTraffic runs autoRenewClients
and disableInvalidClients in the same call, so quota and expiry enforcement
stall too, and an over-quota client keeps transiting for the whole hang. The
online-client refresh and the websocket broadcasts sit later in the same tick.
Give the endpoint its own client with read/write deadlines and a DoTimeout
budget under the poll cadence, close the connection rather than pooling it
for a call this infrequent, and skip the POST outright when there is nothing
to report. Retries stay off: the payload carries per-tick deltas, so a resend
after a failed response leg would double-count on the receiver.
Verified against a listener that accepts and stalls: fasthttp.Do was still
blocked after 8s, the new client returns at its 3s budget.
