- prompt.submit sees and rewrites only the human's own messages, gains the
rewritten text on an image-only prompt, and keeps only typed result fields
- a mod's $.tool.call reaches only the mods loaded before it, attributed to
the caller, instead of re-entering every mod through the pipeline
- a .catch handler shares the failed hook's beneath state so nothing beneath
runs twice; a late next from an abandoned handler is ignored
- hook results are validated before use; detached runs report rejections
- session.end keeps $.state readable until its hooks settle; agent creation
cancellation abandons a waiting session.start hook; agents is read lazily
- a success a hook marks isError becomes a failure; replacement entries clear
on tools/result; per-agent registrations drop with the agent
- $.store writes are serialized per plugin and bounded in UTF-8 bytes;
$.http.fetch bodies are bounded; timers refuse rescheduling after unload
and unload awaits running callbacks; regex matchers reset lastIndex
