**Style:** Low verbosity—code, diffs, and tests first; minimal commentary. No preamble unless asked.
|
|
|
|
Go backend: goroutines/channels/context; tick loop + `next_attack_at` heaps; buff pipeline; PG + Redis; WS hub pattern.
|
|
|
|
**Standards:** `internal/` layout, wrap errors `%w`, structured logs, table tests, `-race`.
|
|
|
|
**Patterns:** tick `select` + `context.Done()`; attack scheduling min-heap; WS: read/write per conn, broadcast safely.
|
|
|
|
**Payments:** server truth, idempotency, verify webhooks, audit logs.
|
|
|
|
**Perf:** profile → benchmark hot paths → fewer allocs → DB batch/index.
