Magic-link validation checks payment ownership, payability, redirect integrity, and one-time consumption. Checkout and invoice actions use the payment URL method and omit the link when no URL is available. ChangesPayment magic links

300-301: 🩺 Stability & Availability | 🔵 Trivial | 🏗️ Heavy liftAdd deterministic concurrency coverage.
verify_and_consume_token()claims the token withadd_option()beforeget_transient(), then deletes it. Releasing two subprocesses before redemption does not ensure that both reach the read before either deletion. One process may complete first, allowing a check-then-delete regression to pass.Add a test-only injection point at the read-before-delete boundary. Coordinate the workers there, then release them and assert that exactly one succeeds. Do not rely on timing or sleeps for this test.

In `@inc/sso/class-magic-link.php`:
- Around line 190-199: Update the changed arrays in the magic-link payment flow,
including the array containing $token_data and the other changed array near the
referenced section, to use short [] syntax instead of array(...), with no spaces
inside the brackets. Preserve all existing keys and values.
- Around line 431-435: Update verify_and_consume_token() to read the transient
before calling add_option() for the database claim, immediately rejecting when
no token data exists; for existing tokens, acquire the claim and re-read the
transient while the claim is held, preserving one-time consumption semantics.
- Around line 431-435: The claim created by handle_magic_link through
verify_and_consume_token must not persist indefinitely. Preserve atomic
add_option acquisition while adding a bounded expiry or reclaiming claims older
than a safe operation window, so interrupted processing can recover without
allowing concurrent redemptions.
- Line 207: Update the flow around the magic-link URL construction in the
relevant method to validate that the exact redirect target uses HTTPS before
calling add_query_arg with self::TOKEN_QUERY_ARG and $token. Reject non-HTTPS
targets before appending or transmitting the authentication token, while
preserving the existing valid-target behavior.
In `@inc/ui/class-checkout-element.php`:
- Line 1014: Update the payment URL check around get_payment_url() to use the
required Yoda condition, explicitly comparing the false|string result against
false while preserving the existing truthy-value behavior.
In `@tests/WP_Ultimo/SSO/Magic_Link_Test.php`:
- Around line 290-292: Extend the payment token assertions in the relevant test
method to verify that token_data['user_id'] matches objects['user_id'],
alongside the existing purpose, payment_id, and redirect_to checks.
