73c05cfa5e feat(a2a): CEO can DM the Auditor and PR reviewers (#623)
* feat(a2a): CEO can DM the Auditor and PR reviewers

A mid-flight PR reviewer or Auditor that's stuck was unreachable — the CEO
had no way to DM them. Both roles now carry dm/read_a2a, so the CEO can open
a 1:1 and they can reply in-thread through the existing CEO-reply path.

Scoped deliberately: the Auditor stays a silent observer to its peers — it
gains no peer-initiation surface (can_a2a_direct routes it through
_check_auditor_a2a, which refuses every initiation target; it can only reply
inside a CEO-opened DM). PR reviewers keep their owning-PM scope. Intake and
Secretary stay excluded — they have their own dedicated chat pages.

NO_COMMS_ROLES drops to {prompter, secretary}; the panel's EXCLUDE_NON_DM_ROLES
matches. KB/docs updated so the 'auditor/pr_reviewer have no dm' claim isn't
left stale.

* test(a2a): smoke guard checks _NO_COMMS_ROLES, not a hardcoded 'auditor'

The dm() runtime guard no longer names the auditor (it now carries dm to
reply to the CEO); it refuses the canonical _NO_COMMS_ROLES set. Assert on
that set so the smoke test tracks the guard, not a stale role name.

* chore(foundation): regenerate verb tables for auditor/pr_reviewer dm+read_a2a

A2A Collaboration Workflow

Overview

Agents collaborate directly through the dm content tool on the roboco-do MCP server, with read_a2a to read what you were sent. There is no roboco_agent_* or roboco_a2a_* tool — A2A is just dm + read_a2a.

Key: A2A is about existing tasks, NOT task creation. Pass the task_id you're collaborating on so the message is linked to it.

Flow

1. Reach out → dm(recipient, text, task_id)      for a direct message
2. Receive   → read_a2a()                        to read incoming A2A message bodies
             → notify_list() / notify_get(id)    to read your notify inbox

Direct Messages (same cell only)

# Direct A2A inside your cell (same team — no policy gate)
dm(
    recipient="be-qa",
    text="Quick sanity check on the rate-limit boundary before I open the PR?",
    task_id="<task>",
)

Cross-cell dm is denied by policy. If you need something from another cell, route it through your Cell PM via escalate_up(task_id, reason) — the PM coordinates across cells.

The CEO

CEO-initiated conversations may arrive and are replied to in-thread like any other unread A2A.

Receiving Messages — read_a2a

Your claim briefing surfaces incoming A2A under unread_a2a — each entry shows the sender and a preview of their latest message. To read the full bodies (and clear them):

read_a2a()      # -> {"messages": [{from_agent, content, created_at}, ...]}

read_a2a() returns only INCOMING messages (never your own sends) and marks them read. It also clears i_am_idle()'s unread-A2A soft-block.

Task Creation Rules

Only PMs create tasks (via the delegate verb). Regular agents cannot create work from a dm.

If a conversation surfaces work that needs a new task:

  1. Escalate to your Cell PM: escalate_up(task_id, reason="Needs a subtask for X")
  2. The PM decides whether to delegate a subtask

Permissions

Most roles can dm (same-cell) and read incoming messages with read_a2a, plus check their notify inbox with notify_list / notify_get.

The Auditor is a silent observer of peers: it never initiates dm to another agent and has no notify. It does carry dm/read_a2a so it can read and reply in-thread when the CEO opens a DM with it — that reply path is stateful (not gated by the peer-initiation rule).

Only PMs and the Board can send ack-required notify signals; regular agents use dm only.
