Problem

When an organization deactivates money management and tries to reactivate it later the same day, the activation fails with an exclusion constraint error (PlatformSubscriptions_unique_period_per_CollectiveId) and the "Activate" button appears to do nothing. It starts working again the next day (UTC). Reported for industra (Aug 14), and earlier for neuromancers / mastodon-japan-net (April).

The mechanism:

  1. deactivateMoneyManagement terminates the platform subscription at now, leaving a period ending mid-day, e.g. [May 25 00:00, Aug 14 13:59:46).
  2. activateMoneyManagementreplaceCurrentSubscriptioncreateSubscription creates the new subscription starting at startOf('day'), e.g. [Aug 14 00:00, infinity], which overlaps the just-terminated period → Postgres rejects the insert.
  3. replaceCurrentSubscription only looks for the current subscription (period @> now), so the already-terminated row is invisible to it and nothing adjusts the new period.

The Inclusive: false in case they start a new subscription on the same day comment in deactivateMoneyManagement anticipated same-day reactivation, but the exclusive end only avoids overlap if the new subscription starts at the termination timestamp, and it actually starts at midnight.

Fix

Keep subscription periods aligned to day boundaries, which the code already half-assumes: createSubscription aligns starts to startOf('day') and replaceCurrentSubscription terminates at startOf('day'). The one mid-day writer was terminate() when called with a mid-day date (from deactivateMoneyManagement, via the default date = now): it now aligns the termination to the start of the day. A subscription created later the same day then starts exactly where the previous one ended ([.., day) + [day, ∞]), so the constraint is satisfied.

This means an organization is not billed for the day it deactivates money management, which the previous code's comment already intended ("we won't bill for the last day").

Also passes the missing transaction to the getCurrentSubscription lookup in replaceCurrentSubscription.

Tests

Two regression tests reproducing the deactivate → same-day reactivate flow (both fail with the exclusion constraint error without the fix). Also verified the platform billing cron tests, which terminate a subscription mid-day, still pass.

📝 Walkthrough

Walkthrough

Subscription termination now uses the start of the termination day. Subscription creation and replacement start at that boundary after mid-day termination. replaceCurrentSubscription forwards its transaction to getCurrentSubscription. Tests cover inclusive, open-ended replacement periods and repeated same-day recreation.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 25faf

The change aligns subscription termination and reactivation boundaries to prevent same-day activation failures, with regression tests covering the reported flow; no actionable merge-blocking risk remains beyond normal checks.

Add coverage for the transaction-scoped lookup.

This test does not pass opts.transaction. It cannot detect a regression in getCurrentSubscription transaction forwarding at server/models/PlatformSubscription.ts Lines 602-604.

Create a current subscription inside an uncommitted transaction. Then call replaceCurrentSubscription with the same transaction. Assert that it replaces that subscription without an exclusion-constraint conflict.

P2 Badge Limit boundary reuse to earlier same-day terminations

When createSubscription receives a backdated start that falls anywhere inside a finite historical subscription, this condition silently moves the new subscription to that row's end, even if the end is days later than the requested start. For example, the pricing migration can request April 1 while an existing row ends April 15; the subscription then begins April 15 while the script records automaticBillingMigration as April 1. Only reuse the boundary when it is on the aligned start day and no later than the supplied start; otherwise retain the overlap error.
