Hub classification 10-02: :8099 in windy-pro is the OLD translate-api / cloud-storage service, not Windy Talk (verified: windytalk has no :8099, only lockfile hash fragments). DEEPGRAM_API_KEY in windy-pro .env.example is a template line for the user-own-key Deepgram feature: owner-approved, approved_by windy-hub, expires 2026-12-31.

"""Compute guard: Windy Mind is the ONLY door to AI compute (Grant, 2026-09-23).
|
|
|
|
Flags code that talks to an AI provider directly instead of through Windy Mind:
|
|
a provider API host, a provider SDK import or dependency, or a raw provider key
|
|
name. Direct calls skip Mind's metering, caps and live-model routing, and they
|
|
spend whichever key happens to be lying around (the audit found Grant's personal
|
|
Max OAuth token inside a platform container).
|
|
|
|
WARN-ONLY for now: the bridge posts `windy-git/compute-guard` as success with a
|
|
"⚠ WARN" description, so nothing turns red. `COMPUTE_GUARD_MODE=block` flips
|
|
findings to failure once the repos are clean (orchestrator's call).
|
|
|
|
- PR heads: only lines the PR ADDS (vs its merge-base with the default branch).
|
|
- Default-branch head: the whole tree (the baseline, and what `report` prints).
|
|
|
|
Exceptions live in ONE file, ci/compute-guard-allow.yml, each with a reason.
|
|
Tests, docs, lockfiles, vendored code and CI config are never scanned.
|
|
Reads the sync's bare GitHub clones on Veron (no docker exec: IO-stall lesson).
|
|
|
|
python3 scripts/compute_guard.py report [repo ...] # whole-tree findings on each default branch
