Centralizes a handful of hardcoded URLs, fetch timeouts, and circuit-breaker
constants behind opt-in environment variables. Behavior is unchanged when
the variables are unset because every call site keeps its current default.
- open-sse/services/usage.ts: extracts CROF_USAGE_URL,
GEMINI_CLI_USAGE_URL, CODEWHISPERER_BASE_URL constants backed by
OMNIROUTE_CROF_USAGE_URL, OMNIROUTE_GEMINI_CLI_USAGE_URL, and
OMNIROUTE_CODEWHISPERER_BASE_URL. Lets operators redirect quota probes
through corporate mirrors or a test fixture.
- open-sse/config/constants.ts: PROVIDER_PROFILES circuit-breaker
thresholds and reset timeouts now honor OMNIROUTE_CIRCUIT_BREAKER_*
env vars (oauth/api-key/local) with the same defaults as before.
- src/shared/utils/fetchTimeout.ts: DEFAULT_TIMEOUT_MS reads
OMNIROUTE_DEFAULT_FETCH_TIMEOUT_MS (fallback 120000) so deployments can
raise the global fallback without changing FETCH_TIMEOUT_MS semantics.
- open-sse/services/chatgptTlsClient.ts: DEFAULT_TIMEOUT_MS and
HARD_TIMEOUT_GRACE_MS now honor OMNIROUTE_CHATGPT_TLS_TIMEOUT_MS and
OMNIROUTE_CHATGPT_TLS_GRACE_MS (defaults 60000 / 10000).
- .env.example: documents the 11 new variables in the URLs and TIMEOUT
sections.
