Dear WPBay Review Team,

Thank you for reviewing Ordrivo RideFlow — Taxi Booking.

In version 7.2.51, driver extra-charge requests and customer approve/decline responses share a per-ride MySQL lock. Each operation reads the current fee metadata only after acquiring the lock, so concurrent updates work from the latest saved array. The plugin verifies the complete array after writing and records the ride event and returns success only after persistence is confirmed. Simultaneous decisions for different charges are retained; only one response can decide a pending charge, and repeated or conflicting responses are rejected. Lock and persistence failures return an error without recording an event.

The prior 7.2.50 tracking timestamps, privacy export fields, CSV nonce/date validation, and administrator/verified-dispatcher access checks remain included. Version metadata, readme, changelog, regression checks, and staging acceptance steps are updated.

Source regression checks, JavaScript syntax checks, and package ZIP integrity checks passed. Live WordPress/database concurrency testing was unavailable in this packaging environment; the exact staging scenarios are listed in docs/TEST-RESULTS-7.2.51.md.

Best regards,
Baris Beydogan
