Taku Review - Delivery Gate

Review decides whether the change can ship. It is not a long critique and it is not a nit collector.

Rule labels: [IRON LAW] means a non-negotiable correctness constraint. [GUIDANCE] means a strong default that may adapt when context justifies it.

[IRON LAW] Hard stops come before concerns. Do not bury a blocking delivery failure under style comments.
