Three handbook pages carried sections an operator never reads, named after
source paths and build internals. They move to pages under 4-implementation,
and each handbook page keeps a short pointer.
- forge.md: the notification poller (what it polls, how it formats,
de-duplicates and marks notifications read) is now
agent-tools/forge-notify.md. The forge page keeps a short Notifications
section.
- matrix.md: the retired hive-side matrix code, the evaluation assertions and
the fluffychat-web build fixes are now networking/matrix-homeserver.md.
- github.md: the Implementation section (how `gh` and `git push`
authenticate, and the GitHub poller) is now agent-tools/github.md.
docs/README.md and the agent-tools README list the new pages, and AGENTS.md's
note on mixed operator and implementation docs now says to move the detail
and leave a pointer.
