Max is a personal plan above Pro at $200/mo, monthly only. Free, Pro, Team, and Founder's Edition machines now stop at 24 GB; the 32 GB and 64 GB ladder rows are locked behind Max. The machine list publishes the locked sizes and the upgrade plan, and a create that asks for a locked size is refused with vm_memory_requires_plan instead of being coerced. Claude-Session: https://claude.ai/code/session_01Dk6H9RfvcYnGTm5yuVgPYX
A user-scoped subscription row now takes its plan (pro or max) from its Price's lookup key, so a Billing Portal switch relabels the row on the next webhook and the cmuxPlan mirror follows. Checkout accepts plan=max (monthly only), an active Pro subscriber asking for Max is sent to a dedicated portal configuration that lists Pro and Max, and the catalog script provisions the Max product, its $200 price, and that portal configuration. /api/billing/plan keeps planId at free|pro for installed clients and adds subscriptionPlanId. Claude-Session: https://claude.ai/code/session_01Dk6H9RfvcYnGTm5yuVgPYX
Public, in-app, and dashboard pricing show Max at $200/mo between Pro and Team, the compare table grows a fifth column with a Largest Cloud VM row, and the copy tests allow 32 GB and 64 GB only in Max copy. Claude-Session: https://claude.ai/code/session_01Dk6H9RfvcYnGTm5yuVgPYX
The New Machine sheet keeps the ladder visible: sizes above the plan ceiling are disabled rows that name Max, with an upgrade button that opens checkout for plan=max. The native pricing screen gains the Max card and column, VMClient decodes the locked sizes and the vm_memory_requires_plan error, and the CLI size copy names Max. Claude-Session: https://claude.ai/code/session_01Dk6H9RfvcYnGTm5yuVgPYX
…ep account.me compatible account.me keeps planId at free|pro for the generated Swift enum and adds subscriptionPlanId, with both checked-in OpenAPI specs regenerated. The billing skill and the VM README describe the Max catalog, the portal switch configuration, and the 24 GB ceiling. Claude-Session: https://claude.ai/code/session_01Dk6H9RfvcYnGTm5yuVgPYX

Order the active personal rows by Max precedence before applying the limit.
The schema permits multiple subscription rows, and the checkout guard is not atomic with Stripe session creation. Three active rows can therefore match this query. Without ORDER BY, the two-row limit can omit Max. resolveProPlanStatus can then report pro, cap VM memory at 24 GB, and reconcile cmuxPlan to "pro".

Do not hard-code Max as the upgrade target.
VmMemoryPlanError can occur when the current plan is already Max, such as when CMUX_VM_PLAN_MAX_MAX_MEMORY_MB lowers the configured ceiling. This responder then tells the Max subscriber to upgrade to Max.
Store the resolved nullable upgradePlanId in VmMemoryPlanError, or resolve it from the entitlement service here. If no higher plan supports the size, return a non-upgrade error.

Do not grant Max from an unknown lookup-key prefix.
This expectation makes every future cmux-max-* Stripe Price authoritative before the application recognizes it. A misnamed or unrelated Price can then grant Max and unlock 32 GB or 64 GB machines.
Classify exact catalog lookup keys first. Use explicit validated plan metadata only when the lookup key is unknown. Add a negative test that an unrecognized cmux-max-* key does not grant Max.
As per path instructions, Max plan and VM-memory gating must use authoritative billing or API plan data, not guessed fallbacks, and must fail closed when authoritative data is unavailable.

Render Max prices with Max translation keys.
latestActiveStripeSubscription includes active Max subscriptions, and StripePlan passes "max" to priceCopy. Both interval branches treat every non-"pro" plan as "team", so a Max subscription can display Team pricing copy. Add explicit Max branches.

Correct the Japanese Max VM-limit copy.
Max supports 32 GB and 64 GB machines. It does not have the 24 GB and 6 vCPU per-VM limit shown for Pro and Team. Update the stale shared-resource label at the same time.
