A paused turn is found by the agent owner's id, so anyone holding one of
the owner's agent keys could resume the owner's own chat with its saved
wiki edit rights. A resume now counts as an API or widget caller when
either the saved state or the resuming request is one, cuts the wiki tool
to wiki_view unless the wiki allows outside edits, and gives the tool
executor the same flags. A request that names an agent, by key or id, may
only resume that agent's turn; otherwise the claim is released and the
request refused.
Public-link visitors run as themselves and reach only wikis they may edit,
so the wiki switch no longer applies to them. Instead every wiki write in
a public-link run waits for the visitor's approval, so the agent owner's
prompt or sources can't steer an edit to the visitor's wiki unasked.
A run from an agent's API key or widget acts as the agent's owner, so it
could rewrite any wiki the owner can edit. A new per-wiki setting,
wiki_outside_edits (off by default), decides whether such runs, and runs
from the agent's public link, get the wiki's edit actions. While it is off
they are offered only wiki_view, and the tool refuses writes itself after
reading the live setting. The owner changes it through the owner-only
/api/sources/<id>/wiki/settings route; tokens can read it but not change it.
