Meta reports the account's session and weekly windows with every Muse reply, and Muse forwards them as usage/changed, but T3 ignored them. Muse was missing from Usage → Limits, and a turn stopped by the quota looked like any provider error. - The adapter hands usage/changed to the driver, which publishes the windows and re-derives them on each status check, because Meta reports usage only with a reply. A window whose reset has passed starts over empty. - The status host reads the experimental account/read, so a login names its account. The same Meta account on several environments, or reported by a hub, counts once. A signed-out Muse now shows as such. - With an API key, which is a gateway such as CLIProxyAPI or API billing, Muse reports no limits itself. The hub reports the account, as for Claude through a proxy. - A CLIProxyAPI usage source lists Meta accounts from the X-Meta-* quota signals the hub records, without an upstream call. - A turn Meta refuses for quota is a usage_limit failure, reset when every exhausted window resets, so Resume at reset works.

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This is a cross-cutting production feature that adds Muse subscription metering, account probing, hub integration, and quota-aware turn recovery across server and client paths. An unresolved Medium finding also indicates expired reset timestamps can remain visible after a window rolls over. Not approved because:

- A Muse report is the account's whole state, so a runtime update now replaces the published windows. A window that has reset since loses its expired reset time instead of keeping it until the next status check. - Serialize usage updates across sessions, so an older report cannot publish after a newer one. - Give account/read 2 seconds. A host that never answers leaves the account unknown instead of discarding the models the probe found. - Publish no usage while signed out, and drop the kept report on logout or when another account signs in.

A status check that drops the kept report because another account signed in now publishes no usage. "Waiting for a report" uses probeFailed, which snapshot reconciliation treats as a failed probe and answers by keeping the last good windows, so the previous account's windows stayed on show under the new account until its first reply. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Muse's usage reports name no account, so the driver labeled each one with the login the snapshot named when the report arrived. A report from a host that started before a logout or another login could land under the new account, and one that arrived while signed out was kept for whoever signed in next. The driver now keeps an account generation, which a status check advances when it finds a logout or a different login. Each host reads the generation when it starts and every report carries it; only reports from the current generation are kept or published. Status checks and reports share one permit, so a check and a publish cannot interleave. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
main moved the shared provider modules into packages/provider-core (pingdotgg#17299, pingdotgg#17302). The usage-limit, snapshot and managed-provider changes follow them there, and the Muse files import from the new paths. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A reset time later than a JavaScript Date holds threw when formatted. From the hub it failed the whole account read, the hub's Codex and Claude accounts included; from Muse it passed the usage/changed schema and would throw in the driver. The usage/changed schema now bounds its instants to the Date range, so such a report is skipped like any other unreadable one, and the hub parser drops a window whose reset is out of range.

main moved Muse Code into packages/provider-muse (pingdotgg#17331). This branch's Muse changes follow it there, and its new usage-limit module moves along as provider-muse/src/server/usageLimits.ts. The provider-muse server entry exports the hub mapping that the CLIProxyAPI usage source imports. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

148-155: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low valueAdd a comment for the interaction between the timeout and the host lifetime.
Effect.timeout(2_000)interrupts the fiber that awaitsEffect.tryPromise. The underlyingaccount/readrequest is not cancelled. The scope closes the host after the probe, so a late response is dropped. This behavior is acceptable. The code does not pass anAbortSignaltorequest, so a note helps later readers. The 12-second outer timeout instatus.tsalso bounds the total probe time.The
Effect.optioncall also hides decode failures. A decode failure and a missing method give the sameundefinedaccount. Consider a debug log to tell them apart.🤖 Prompt for AI Agents

Meta reports the account's session and weekly windows with every Muse reply, and Muse forwards them as
usage/changed. T3 ignored them, so Muse was missing from Usage → Limits, and a turn stopped by the quota showed as a plain provider error.How it works
usage/changedto the driver. The driver publishes the windows, and re-derives them from the newest report on each status check, because Meta has no usage endpoint and reports usage only with a reply. A window whose reset has passed starts over empty. Each report replaces the published windows, and reports from several sessions are applied one at a time. Before the first reply after a server start, Limits says Muse will report with its next reply.account/read, which names the login's account. A host that does not answer it within 2 seconds keeps its models and leaves the account unknown. The same Meta account on several environments, or reported by a hub, counts once instead of once per machine. A signed-out Muse now shows as signed out, with no usage. Reports name no account, so each counts for the login its Muse host started under: a logout or another account signing in drops the kept report and clears its windows, and reports from hosts that started before are ignored. A session whose host started under the old login reports again once its host restarts; new sessions report at once. A Muse withoutaccount/readkeeps today'sunknown.X-Meta-*quota signals the hub records from the same Meta event, with no upstream call. It skips a Meta account the hub has not observed, so a CLIProxyAPI that does not record them adds no rows. feat(meta): record Meta subscription usage and pass it to Muse ntindle/CLIProxyAPI#4 records them, and also forwards the event afterresponse.completedso Muse sees its quota through the proxy.usage_limitfailure. ItsresetAtis the latest reset among windows the last report showed exhausted, so Resume at reset works. Muse words the refusalAPI error 429: Subscription quota exhausted… (rate_limit_error)and drops the reset time Meta sent with it.Mobile's Limits heading gains the Muse label; web already takes it from the driver metadata.

Known limit: Muse's reports name no account, so a report is only as reliable as the last status check. A host that starts after a
muse loginoutside T3, but before T3's next status check, counts under the previous login until that check runs. Likewise, a host that starts before T3's first account check after a server start counts under the first login that check names. Closing these gaps would mean each session host running its ownaccount/read.Found while testing on Windows, still on
main: Muse 1.4.3 accepts aturn/startworkspaceRootsentry only as the verbatim canonical path (\\?\C:\…), and T3 sendsC:\…, so every Muse turn fails on Windows. The live check above worked around it; #17163 fixes it separately.Created with Claude Opus 5.5 in Claude Code.
