Explanation
PASS. The pull request changes only Grok provider code, Grok tests, and provider documentation. The new enrichment sends the existing Grok credential to Grok's billing endpoint and adopts only usage percent/product usage.
adopt_grpc_percentpreserves the ACP period, subscription tier, and prepaid balance. It does not add identity, email, account labels, or cross-provider data. The isolated-account guard still blocks ACP fallback, and no shared-codeProviderIdbranching was added.

Explanation
PASS. The PR adds no credential-file or keyring mutation. The new token use in
credits_proxy.rsformats an Authorization value only for the existingfetch_billingHTTP request. The new tracing line logs only the returnedProviderError; the error paths contain fixed status, parse, auth, timeout, or transport messages and do not include request headers or response bodies. The tests use synthetictokenandstale-tokenvalues and add no snapshots or plaintext credential files. No cookie, API key, OAuth credential, or authorization header reaches a changed log, user-facing error, snapshot, or file.

Explanation
The PR changes visible Grok usage data. The new ACP path adopts 0% or a published percentage, and
result_from_billingconverts that value into the displayed rate window. The added test confirms the user-facing usage becomes 0%. The supplied PR description says “Desktop proof, not yet run” and provides only a planned procedure. It includes no screenshot or completed proof note from a fresh Windows build.Resolution

Review comments at @rust/src/providers/grok/cli_fallback_tests.rs:
- Around line 590-624: Add a success-path test alongside
acp_wallet_answer_is_enriched_on_the_fallback_path that makes the bearer billing
request fail and the CLI fallback’s enrichment request succeed with a known used
percentage. Assert both billing requests are made, the CLI runs once, and the
returned answer adopts the percentage and marks it as wire-published.
Review comments at @rust/src/providers/grok/credits_proxy.rs:
- Line 295: Update resolve_cli_unknown_usage so it adopts a successful gRPC
result through adopt_grpc_percent only when the ACP period is active and matches
the period used to validate the implicit zero; otherwise, do not adopt that
result. Preserve the existing ACP reset and window values only when this period
check passes.

Require an active, matching period before adopting an implicit zero.
parse_credits_response retains expired periods, and the ACP fallback accepts a period-only response when it includes a prepaid balance. resolve_cli_unknown_usage then adopts a successful gRPC result without checking the ACP period. The gRPC parser validates that its own period is active, but adopt_grpc_percent preserves the ACP resets_at and window_minutes. A current gRPC zero can therefore be paired with an expired ACP reset. Require an active ACP period that matches the period used to validate the implicit zero before adopting it.

95cfee32a(Keep Grok weekly credits window on zero-usage weeks)Summary
When the Grok CLI answers over ACP with a wallet only (prepaid balance and billing
period, no quota percent), the answer is now checked by the same bounded grok.com
percent lookup that the credits proxy path already uses. The result:
so the weekly Credits window stays on the card at 0%.
answer with usage unknown.
Upstream reference: CodexBar
ad0c5679b(steipete#4679). Upstream appliesresolvingUnknownUsageto ACP wallet-only credits, removes the OAuth short-circuit, returns the proxy answer only
when a percent is present, and updates
docs/grok.md. The Windows port does the same inthe ACP fallback. The docs change lives in
docs/PROVIDERS.md, which is the Windowsprovider reference, and it describes the new ACP rule.
Behavior and scope
rust/src/providers/grok/mod.rs:285: the ACP fallback result goes throughresolve_cli_unknown_usageinstead of being returned as is. This runs only after thebearer path fails for the ambient CLI login, as before (upstream Fix Grok CLI billing: use _x.ai/billing ACP extension method steipete/CodexBar#4595 ordering).
rust/src/providers/grok/credits_proxy.rs:280:resolve_cli_unknown_usagereturns theanswer unchanged when it already has a percent or the credentials are expired. Otherwise
it makes one bounded grok.com call (
PERCENT_RETRY_TIMEOUT, 6 seconds) and merges theresult with
adopt_grpc_percent(credits_proxy.rs:211), which is the same merge thecredits proxy uses.
fetch_cli_acp_without_login). Thatpath has no bearer to send, so there is nothing to enrich with. The answer is shown with
usage unknown, as before.
Tests added (6)
All in
rust/src/providers/grok/cli_fallback_tests.rs, using mocked local endpoints andsynthetic data (
example.com-style fixtures, fake tokens):wallet_only_cli_answer_adopts_a_validated_zero_week: an active weekly period withomitted usage becomes 0% used, and the prepaid balance and tier are kept.
wallet_only_cli_answer_adopts_a_wire_published_percent: a published 37% is adopted.cli_answer_with_a_percent_is_never_enriched: no grok.com call (expect(0)).failed_percent_enrichment_keeps_the_wallet_with_unknown_usage: a 500 keeps usage unknown.expired_credentials_skip_percent_enrichment: no grok.com call (expect(0)).acp_wallet_answer_is_enriched_on_the_fallback_path: the full fallback path, with theCLI called once and the grok.com call made for both the bearer phase and the enrichment.

Unit tests cover the merge rules, the no-call rules, and the failure fallbacks. The grok.com
