The revoke handler still gated admin via `session.Role == "admin"`, which no longer compiles since api.Session has no Role field. Replace with the same two-track pattern the sibling authorizeSessionCancel / authorizeSessionApprove already use: - Stateless admin API key short-circuits via `session.UserID == apiKeyAdminUserID` (no DB row exists to resolve permissions from). - Group-based admins fall through to HasPermissionAPI; the {admin, *} wildcard in DefaultAdminPermissions matches revoke-any:purchases there. Drop the dead `Role` field from the revoke test sessions; the admin test now pins the apiKeyAdminUserID short-circuit, and the existing RevokeAny test already covers the group-admin path via HasPermissionAPI. Also fold in the trailing pre-commit fixes that were red on the previous push: - gofmt: realign struct-field padding in TestRevokePurchase_AzureReturnClientError. - go mod tidy: promote armreservations from indirect to direct (the revoke handler imports it directly). Free-cancel window enforcement (AzureRevocationWindowDays + windowClosesAt check) and revoke-call idempotency (early return when record.RevokedAt is already set) are unchanged.

A scheduled execution can be cancelled at $0 via the existing revoke endpoint before the scheduler fires. Two-tier revoke path: - status=scheduled: CancelExecutionAtomic (CAS) transitions to cancelled; no cloud API call, returns 200 with explicit "no cost incurred" message. - status=completed (existing): provider SDK call via purchase_history path. revokePurchase now tries GetExecutionByID first; falls through to the existing purchase_history lookup when no scheduled execution is found. authorizeSessionRevokeExecution mirrors authorizeSessionRevoke but uses CreatedByUserID (not CloudAccountID) for revoke-own scoping. FireScheduledDelayedPurchases (purchase.Manager) drives the scheduler tick: queries GetScheduledExecutionsDue, CAS-transitions scheduled->approved, stamps ApprovedBy="scheduler", calls executeAndFinalize.

Replace all three with a type alias pointing at internal/mocks.MockConfigStore. Changes to internal/mocks/stores.go: - Add Fn-override fields imported from the api and purchase local mocks (GetCloudAccountFn, GetPurchasePlanFn, SetPlanAccountsFn, SavePurchaseExecutionFn, GetPlanAccountsFn, and 6 others) so callers that used those fields keep working without changes. - Add isExpected guards to recommendation-cache and RI-utilization-cache methods and to CancelExecutionAtomic so existing tests that call these without explicit On() expectations don't panic (matches the "opt-in" pattern the per-package mocks used via hasRecExpectation / hasExpectation). - Add 8 interface methods that were missing from the shared mock but present in all per-package variants: GetExecutionsByStatuses, GetPlannedExecutions, GetStaleApprovedExecutions, ListStuckExecutions, GetScheduledExecutionsDue, MarkCollectionStarted, ClearCollectionStarted, StampRIExchangeApprovedBy. - Add compile-time check: var _ config.StoreInterface = (*MockConfigStore)(nil). - Promote GetGlobalConfig and GetPurchasePlan to return sensible defaults when no expectation is registered (matches the api-package behaviour these tests relied on). Per-package files reduced to a single type alias line each. The scheduler test also had stray suppression/Tx method stubs added in a later commit; those are removed because the methods already live on the shared mock. Intentionally left local (incompatible shape or semantics): - internal/analytics/collector_test.go: mockConfigStore (lowercase) -- hook-field only pattern with no testify embedding; analytics-specific subset; different name. - internal/server/test_helpers_test.go: mockConfigStoreForHealth -- all-zero-value stubs for health check tests; distinct type name; no testify embedding. - internal/server/handler_ri_exchange_test.go: mockConfigStoreForExchange -- test- specific struct overriding a handful of methods. - internal/server/handler_coverage_test.go: mockConfigStoreForExchange{Complete, Fail,Stale} -- per-scenario stubs with distinct type names.

A status='scheduled' row never matches, so the CAS returned zero rows on the happy path -- the handler then surfaced 410 "revocation window has closed" even when the window was wide open. The user would pay the cloud charge AND see a "cancelled" attempt in the UI -- the worst possible outcome. The bug was hidden by mocks defaulting CancelExecutionAtomic to (true,"cancelled",nil), so every test in the scheduled-revoke suite was green against the wrong SQL. No pgxmock test exercised the WHERE clause. Fix: introduce CancelScheduledExecutionAtomic with the correct `WHERE status = 'scheduled'` guard and switch the handler to it. The two CAS variants are kept distinct on purpose -- the scheduled-revoke flow surfaces 410 ("scheduler already fired") on race-loss, while the pre-purchase cancel flow surfaces 409 ("not pending"). Sharing one method would conflate the two race outcomes. Regression test TestRevokePurchase_ScheduledExecution_BugReg_HappyPathCAS pins the call to CancelScheduledExecutionAtomic with an Expect and adds an AssertNotCalled for CancelExecutionAtomic; verified to fail pre-fix (mock expectation unmet, wrong method called) and pass post-fix.

Replace the action switch with a package-level lookup table so the complexity no longer grows with the task list; adding a task type stays a one-line change. Also close the test gap on the Gmail-style pre-fire delay scheduler sweep: FireScheduledDelayedPurchases / fireOneDue had no unit coverage of their result accounting or CAS-race classification (only the dispatch wiring was mocked). Add scheduled_fire_test.go mirroring reaper_test.go: - no-due-rows and list-error paths - CAS lost to a concurrent revoke -> RaceLost, not Errored, and no SDK fire (the safety property that prevents double-charging a revoked purchase) - row-vanished (ErrNotFound) -> RaceLost - hard DB error on the CAS -> Errored (per-row isolation, sweep still succeeds) Each race/error test fails if the classification regresses (verified by flipping fireOneDue's return).

TransitionExecutionStatus(pending|notified -> scheduled) -- atomic CAS. 2. Stamp ScheduledExecutionAt + ApprovedBy on the returned post-CAS row. 3. SavePurchaseExecution to persist the stamps. Before this fix a concurrent Cancel that landed between the approve handler's SELECT and its SavePurchaseExecution would be silently overwritten: the cancelled row would become status="scheduled" and eventually fire the cloud SDK call the user explicitly revoked. The CAS ensures the write succeeds only when the row is still in pending or notified; a concurrent cancel causes ErrExecutionNotInExpectedStatus which surfaces as a clear error to the caller.

if all retries fail, the endpoint returns a revokeReconcilePendingResult (HTTP 207 body with code=RECONCILE_PENDING, azure_returned=true) so the frontend shows a non-retryable toast rather than prompting the user to retry a refund that Azure already issued. - loadAndRevokePurchaseHistory detects a row with revocation_in_flight=true and revoked_at=nil and immediately returns 207 RECONCILE_PENDING to prevent any duplicate Azure Return call on retry. - purchase.Manager.FinalizeInFlightRevocations sweeps rows matching GetPurchaseHistoryInFlight and retries MarkPurchaseRevoked with 2s/6s backoff per row;

The substring-match approach had two failure modes: - False positives: any error whose .Error() string contains "400" (e.g. a network timeout "timeout after 400ms") would be misclassified as a client error, hiding transient infra problems from the operator. - False negatives: Azure refund-policy errors with HTTP codes not in the literal set (e.g. 403, 405) would be escalated as 500. The typed approach classifies exactly the HTTP status codes Azure uses for policy violations and bad requests (400, 403, 404, 405, 409, 422); all other errors (transport errors, 5xx, plain errors) correctly classify as server-side.

This eliminates the tail of RefundPolicyViolated failures caused by clock skew between CUDly's clock and Azure's at the window boundary. The safety margin is applied only in the local pre-flight check. The value stored in purchase_history.revocation_window_closes_at remains the unmodified Azure deadline so operators can see the true expiry. Additionally, detect RefundPolicyViolated errors from the Return API via the new isAzureWindowEdgeError helper (typed errors.As on *azcore.ResponseError, checking ErrorCode == "RefundPolicyViolated") and map them to a clean 422 with "window has closed" message rather than the generic "Azure refund rejected" 400 path. This handles the race where our safety-margin check passes but Azure's clock disagrees mid-flight.

The old code read the status from the DB and then only dispatched to revokeScheduledExecution when it was "scheduled", but a concurrent writer could flip the status between the read and the CancelScheduledExecutionAtomic call. Drop the pre-check and let CancelScheduledExecutionAtomic's WHERE status='scheduled' CAS decide; a lost CAS returns 410 as expected. Finding C: Distinguish a genuine DB error (non-nil execErr) from a missing row (nil, nil). Before the fix, any non-nil execErr was folded into the "execErr == nil && ..." condition and silently swallowed, falling through to the history lookup.

The finalize_revocations sweep would then treat the row as "Azure succeeded, DB write pending" and retry MarkPurchaseRevoked unnecessarily, potentially marking a purchase as revoked when it was never actually returned. Fix: call ClearRevocationInFlight (new store method) on all Azure Return error paths so the row reverts to its original status.
