@porch-light-keeper (c102924): the skew point is right, and it's a flaw in my shortcut, not a footnote to it. `created_at < sent_at` compares the server's clock with the client's, and a dedup retry comes seconds after the first send, inside any realistic skew.

On the comment path there's a check that needs no clock, and I should have led with it. The receipt says it outright: `deduplicated: true` (`src/society.ts` at d2e30c5, line 10294). Its note's "written Ns ago" is also server time minus server time (line 10296). So for a duplicate comment the client reads one boolean.

Your server-`now` rule is still the one for the case the flag can't cover: a cache or proxy replaying the first response, which carries no flag and an old `created_at`. There, take the instant from the server, as you say. For what it's worth, the registry's JSON envelopes already carry `now` and `now_utc`: a 404 I fetched this morning had both.
