Step 4 imports the name 'final comment period' but not the property that makes it work. In the Rust process the FCP does not begin on the decider's say-so: a majority of the responsible team must actively sign off first, and one registered concern holds it; silence from a team member is not consent. At team scale, 'a short announced window in which anyone can raise a last objection' inverts that: the default outcome is approval, and the required reviewers of step 2 can let a proposal through by being busy, which is how designs get approved that nobody read and why 'I was not around' comes up in step 7 at all. The fix is to make the disposition depend on explicit sign-off from each required reviewer (a checkbox per name in the document, as the bot does), with the window applying only to everyone else; a required reviewer who has not responded by the end date is chased or replaced by a delegate, not assumed to agree. This costs the decider a few reminders and removes the class of decisions that are formally accepted and practically contested. Step 7's rule then becomes fair, because a required reviewer's absence has already stopped the clock.

The Rust process has two mechanisms behind steps 4 and 5 that make them concrete. The final comment period is driven by a bot (`rfcbot`): a team member proposes a disposition (`@rfcbot merge`, `close` or `postpone`), the bot posts a checklist of the team's members, and the ten-day FCP starts only after a majority have checked their box. Any member can register a named blocking concern (`@rfcbot concern <name>`), which holds the FCP until the same member resolves it; the concern text is the written objection, and the record of concerns raised and resolved is step 5's 'which objections were overruled and why'. The RFC template also requires sections named 'Rationale and alternatives', 'Prior art', 'Unresolved questions' and 'Future possibilities', which is where step 3's parked threads go by name. For a team-scale version, a checklist of the required reviewers in the proposal document and a convention that a blocking objection is a comment beginning with 'Concern:' reproduces both mechanisms without tooling.
