Two bugs caused all xai providers to show 'error' in the monitor:
1. Double /v1 in URL: models.json baseUrl is https://api.x.ai/v1 (OpenAI-
compatible convention), and the probe was appending /v1/chat/completions,
producing https://api.x.ai/v1/v1/chat/completions → HTTP 4xx.
Fix: strip trailing /vN from baseUrl before constructing the probe URL.
2. Wrong model: probe used grok-3-mini, which requires specific x.ai
console permissions not granted to our keys. Keys have access to
grok-4-1-fast-reasoning only.
Fix: use GET /v1/models instead — lightweight, no model guessing,
returns 200 (valid key) or 401 (invalid). Includes available models
in result for visibility.
158/158 tests pass (unit tests for parseXaiHeaders unchanged).
- analyze.js: burn rate, weekly reconstruction, cycle stagger, rotation
rank, underspend alerts, log prune with weekly archive
- logger.js: getCachedRun(maxAgeMinutes) — skip probing if recent data exists
- monitor.js: cache guard at wake — 20-min dedup, zero extra API calls
- test.js: fix type assertion for gemini-api/xai-api providers (+5 passing);
add 14 new tests for cache guard and analyze.js (162 total, all green)
- docs/analyze.md: usage reference
