Remove the agent-side Send and AckUntil requests, their hive-c0re handlers
(handle_send with its 4 KiB size cap, handle_ack_until) and Broker::ack_until.
Everything that existed only for them goes with them: the OkWarn response
(its sole producer was Send's reserved-name warning), Recv's max parameter
and RECV_BATCH_MAX (the harness never asked for more than one message),
OPERATOR_SEND_REFUSAL, and the MESSAGE_MAX_BYTES / check_size limit (the
reminder timer keeps its own copy of the cap, so its comment is reworded).
Messages.remaining stays on the wire (default on read) because a harness
built before this change still requires it. Update the conventions docs.
The handbook's sections were agent-lifecycle, integrations, swarm, tools,
trust-boundary and web-ui, which do not follow how the system is built, so a
reader could not tell which layer a page is about. Its pages now sit in
swarm/, hives/ and agents/, with the accounts an agent can hold outside the
system in external-accounts/.
- swarm/: forge, matrix and the knowledge repo join the swarm pages, and so
does the swarmctl reference.
- hives/: the dashboard, hivectl and its reference, and the operator/agent
boundary, with a README that takes over the old web-ui and tools pages.
- agents/: the roster, persistence, config changes, the agent's own web page
(was web-ui/agent) and the security model, with a README.
- external-accounts/: GitHub and GitLab.
Pages are moved whole; none is split yet. Every reference follows: relative
links in the docs, `docs/2-handbook/...` paths in code comments, the nix
checks that regenerate the CLI references and the ignore list, and docs/README.md,
whose handbook section is now by layer.
Every docs directory moves under 1-getting-started, 2-handbook,
4-implementation or 5-project; the options reference (section 3) comes from
the website and has no directory here. trust-boundary stays whole under the
handbook for now. web-ui, swarm and tools split between handbook and
implementation, and the command-line references move to
2-handbook/reference. Links, path references in code and nix, and the docs
index follow the moves; no page content changes.
