This is a worthwhile provider-quota direction, and the second commit correctly addresses the three current automated findings. The credential destination is also narrowly pinned to the two official hosts rather than derived from an arbitrary provider URL. Before moving the draft to Ready, please:
I am leaving this as preliminary draft feedback rather than an approval or rejection. The implementation remains a strong review candidate once those evidence and readiness steps are complete. |

Reviewed exact head e815a40. The feature direction is useful, but the draft is 400 dev commits behind and is not ready for approval. The Grok review and my earlier feedback still identify the required evidence: define empty limits fallback behavior, prove the TIME_LIMIT and usage denominator semantics with a sanitized real contract sample, retain the non-canonical host credential guards, add the user-facing and security documentation, run the privacy scan, and rerun full exact-head CI after rebasing. Keeping this open as a draft rather than merging.
Probe the /api/monitor/usage/quota/limit endpoint for the GLM Coding Plan on both Z.AI regions (api.z.ai and open.bigmodel.cn), including the OpenAI Responses endpoint (/api/v1) on BigModel. Parses the limits-array payload, falls back to legacy field-name payloads, and dispatches for zai, glm, glm-cn, and zhipu-bigmodel-coding. The pay-as-you-go /api/paas/v4 route never probes.
Require unit+number to identify the five-hour (3/5) and weekly (6/1) windows so unrelated token rows cannot overwrite them. Fall back to the legacy field-name parser only when the limits array is absent, and point the pay-as-you-go regression at a dispatched provider alias.

Compare
Add the provider/quota documentation note for the new Bearer-authenticated destination and keep the pay-as-you-go tests' fixture key short enough to stay below the privacy scan's bearer-token threshold.
Record sanitized live probe responses: the v2 protocol carries the monthly MCP TIME_LIMIT row (search-prime/web-reader/zread usage details), the newer protocol reports CREDIT_LIMIT token rows only. Proves the TIME_LIMIT row is the 30-day MCP window rather than a fixture we invented.

Lines 592-599 list supported coding-plan paths but do not state that /api/paas/v4 is the pay-as-you-go route and is never probed or sent the key. Also state that legacy field parsing applies only when limits is absent. If limits is present but empty or unsupported, no legacy quota bar is produced.

Add a non-canonical-host regression case for glm or glm-cn.
Lines 914-949 verify a canonical BigModel request through zhipu-bigmodel-coding. They do not verify that the newly dispatched glm or glm-cn aliases suppress probing for a non-canonical URL. Add a test that uses one of these aliases with a lookalike host and asserts that fetch receives no request. This verifies that the API key is not sent after alias dispatch.

Approved exact head 4729b37d60f11c087ee32ac63f5f44f821e18d84 after independent code and credential-boundary review.
The probe sends the configured Bearer credential only to the exact canonical Z.AI or BigModel coding-plan host selected by the provider route, rejects redirects, and makes no request for custom or pay-as-you-go destinations. The modern limits contract, explicit empty-array behavior, supported 5-hour/weekly durations, monthly MCP row, and legacy-only fallback are covered with sanitized live-protocol fixtures. The user documentation matches the implemented regional behavior.
Local exact-head validation passed: 105/105 provider-quota tests, typecheck, privacy scan, and the documentation production build. Cross-platform CI and React Doctor are green on this SHA. No Go-runtime counterpart exists for this TypeScript provider-quota/docs change.
