Used only when mentions.invoker_source in rules is set to allowlist-doc. Otherwise the agent uses the WRITER capability set as its invoker list.

# ----- allowlist begin -----
invokers: []   # accountIds (z6Mk...) allowed to mention the agent
# ----- allowlist end -----

• v1 leaves this empty and uses writer-capabilities instead.

• v2 (deferred) introduces a "members" tier with a more restrictive ruleset; that mode reads this list.
