import { DatabaseService } from '../services/DatabaseService';

/**
|
|
* Shared diagnostic logging gate. Reads `developer_mode` from
|
|
* DatabaseService, which caches the global_settings snapshot internally
|
|
* and invalidates on write, so hot-path callers can query freely.
|
|
*
|
|
* Acceptable: error paths, per-request paths, per-tunnel paths,
|
|
* once-per-stream paths. Each call costs one Map lookup in Node's
|
|
* require cache, one method call into the cached settings object, and
|
|
* a property access. Fine for these cadences.
|
|
*
|
|
* NOT acceptable: per-frame paths in steady state (WebSocket message
|
|
* loops, container stats streams, log-tail demuxers). The require
|
|
* lookup and singleton dispatch add up at thousands of calls per
|
|
* second. If you need diagnostic logging in a per-frame loop,
|
|
* snapshot the result once outside the loop and read the snapshot
|
|
* inside.
