Problem

bb's usage panel supports plan-level windows (provider/usage →
windows: [{label, usedPercent, resetsAt}]), and the daemon validates them,
but bb-zcode answered with windows: [] since v0.7.0 — the panel showed only
the plan label, never the actual Coding Plan quota state.

Upstream sync a60ba6a (CLI 0.17.1) documents the quota-remaining endpoint
the Desktop usage dashboard reads:

GET {api.z.ai | bigmodel.cn}/api/monitor/usage/quota/limit
authorization: <Coding Plan API key>   (raw, no Bearer)

Same origins and credential family src/coding-plan.ts already uses.

Change

• CodingPlanHost.usageWindows() — one bounded GET via the existing
  request() plumbing, authorized by the short-lived project token (the key
  upstream's usage dashboard uses); any account failure degrades to
  undefined.
• quotaWindows(limits, now) — pure mapper following the upstream dashboard
  identity rules: 5-hour window (TOKENS_LIMIT/unit 3/number 5),
  Weekly window (TOKENS_LIMIT/unit 6), MCP quota (TIME_LIMIT/unit 5/
  number 1), in a fixed display order. The native percentage is already
  used-percent; a window requires a finite 0..100 percentage, and resetsAt
  is only reported while nextResetTime is in the future. Windows the
  service does not number stay hidden rather than guessed.
• provider/usage now serves them behind a single-slot 60 s cache keyed
  by the exact request payload, so panel refreshes neither respawn the
  sessionless CLI probe nor re-query the account service. The quota fetch
  rides only the provider/usage probe — never model/list /
  provider/health, which share probe() and run often. Test seam:
  usageCacheTtlMs.
• Quota failures keep the previous plan-label-only answer (windows: []).

Verification

• 10 focused regressions: mapping for both families with raw-token auth
  assertion, degradation on HTTP 500 / no-plan / signed-out, panel wiring,
  cache hit within TTL and re-probe at expiry, SDK schema conformance of the
  reply (providerUsageResultSchema).
• npm run typecheck, full suite 264 tests green, format:check clean.
• Live-verified through the real Desktop sign-in (GLM Coding Max):
  5-hour 75% / weekly 19% / MCP 1% with real reset timestamps. bigmodel
  family: fixture coverage only.

Docs/knowledge updated: CHANGELOG, docs/configuration.md, feature roadmap
(stage-2 note), new knowledge/contracts/quota-usage-protocol.md (live
verified on zai; records the wire shape, window identities, and the
adjacent-but-unwired reset-opportunity API), knowledge/log.md.

Summary by CodeRabbit

• New Features
  • The provider usage panel now displays available 5-hour, weekly, and MCP quota windows, including usage percentages and reset times. Windows without reported usage remain hidden.
  • Usage results are cached for up to one minute. If quota information is unavailable, the existing plan-label-only response remains available.
• Documentation
  • Updated configuration guidance and added documentation about quota reporting and its behavior.

Walkthrough

The provider usage response now includes mapped 5-hour, weekly, and MCP quota windows with usage percentages and reset times. The bridge caches successful responses for 60 seconds by default. Quota retrieval failures leave the prior plan-label-only response available.

Changes: Provider quota usage

Layer / File(s)	Summary
Quota mapping and retrieval src/coding-plan.ts, tests/coding-plan.test.ts	CodingPlanHost maps matching quota limits to ordered windows. It accepts finite percentages from 0 through 100 and includes only future reset times. Tests cover both provider families and cases where quota data is unavailable.
Provider usage response and cache src/bridge.ts, tests/bridge.test.ts, knowledge/contracts/quota-usage-protocol.md, knowledge/index.md, knowledge/log.md, knowledge/decisions/feature-roadmap.md, docs/configuration.md, CHANGELOG.md	provider/usage returns quota windows and caches successful responses by parsed request payload. The tests check cached and uncached requests, response validation, and empty windows. The documentation records the quota mapping, endpoint, and cache behavior.

Merge Risk: Low · up to 985e9

After a temporary quota-service failure, the usage panel may show no quota windows for up to a minute. This bounded delay does not appear to block merging.

Full details: Title check

Explanation

The title "feat(bridge): report Coding Plan quota windows in provider usage" matches the main change. The changeset adds quota-window reporting to the provider/usage response in src/bridge.ts, backed by a new quotaWindows mapper and CodingPlanHost.usageWindows in src/coding-plan.ts. The title is specific, concise, and uses the conventional commit form. It does not cover the 60-second cache or the fallback behavior, which is acceptable for a title.

Full details: Docstring Coverage

Explanation

Docstring coverage is 25.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 4 functions across 4 files. (6 skipped: 6 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

2457-2465: Minor · Stability & Availability · Quick win

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Quota failures are cached as successful empty results.

This code caches every ok response when models are available. That includes responses where usageWindows() failed and probe substituted []. A transient HTTP 500 or timeout then suppresses retries for usageCacheTtlMs (60 seconds). This matches the learning to avoid caching failed or empty results.

Track failure separately from an empty list. Skip the cache write on failure.

Proposed fix

-      const windows: UsageWindow[] = options.quota
-        ? ((await account.usageWindows?.()) ?? [])
-        : [];
-      return { snapshot, planLabel: account.planLabel ?? null, windows };
+      const fetched = options.quota
+        ? await account.usageWindows?.()
+        : undefined;
+      const windows: UsageWindow[] = fetched ?? [];
+      return {
+        snapshot,
+        planLabel: account.planLabel ?? null,
+        windows,
+        quotaFailed: options.quota === true && fetched === undefined,
+      };

Then in the provider/usage handler, destructure quotaFailed and use if (available.length && !quotaFailed) for the cache write. Test accounts without usageWindows would then not cache. Update the test at tests/bridge.test.ts lines 379-392 only if needed.
