Scope changed mid-week; flagging now and proposing a new date.
02

Customer escalation pulled my focus; proposing Friday instead of Wednesday.
06
Found a blocking bug that needs a fix before we can ship.

Vendor SLA on the integration is slower than estimated; need a week.

Stakeholder feedback came in after the deadline lock; incorporating.

Asking for a 3-day extension to do this right rather than redo it.
