/**
 * One-off diagnostic: test the e-Atria bridge's care-context-link endpoint
 * under two candidate paths to determine which one is actually live, since
 * app/Libraries/Abdm/Sync/AbdmGatewayPushClient.php::pushCareContextLink()
 * calls '/api/v1/abdm/gateway/care-context/link' and gets HTTP 404, while
 * the sibling pushRecord() correctly uses '/api/v3/records/push'.
 *
 * Does NOT print the bridge token. Only prints HTTP status codes + short
 * response bodies so we can see which path (if any) the bridge recognizes.
 *
 * Usage: php83 check_care_context_link_endpoint.php
 * Delete this file after use.
