Subject: [PATCH] Say what counts as watched in the federation register, not
 which issue will decide it (#489)

The `WhatWasPlayed` item of `SharedItem` in `src/server/federation.rs` described
part of what a federation act may share as "whatever #60 decides counts as
watched". #60 decided it: it closed as completed on 2026-08-27, nine hours after
this sentence landed, and `src/playback/watched.rs` arrived two hours after that
applying the rule, which is 0060's and takes 0058's boundary rather than stating a
second number. The item now says that and names the module.

What that prevents is a person being unable to read what they are consenting to.
`SharedItem` is the closed set a federation act enumerates, and this module's own
header says the enumeration is what the core is bound by afterwards, so it is the
register somebody opens to find out exactly what leaves the device when an act is
performed. One member of it answered with an open question, and the natural
reading of a closed issue is that the answer exists somewhere the file does not
name.

Everything else in the item is kept. 0068 still places it closest to the
sensitive kind, its reason is unchanged, and what was played, when and how far it
got are untouched. No member is added to or removed from the set.

The sentence went stale within hours of landing rather than landing refuted,
because the change that decided the rule had no reason to open the federation
register, and the correction at the site says so in those words.

It was found by reading every issue number this tree names outside
`docs/decisions/` against the state of that issue on the tracker.

Nothing else moves. No behaviour, signature, variant or refusal.

Closes #489
