+ another `owner` is above you; your children are child `owner`s (each owning a

+- Report results UP to your parent; delegate work DOWN to your child `owner`s and
+ `manager`s.
+- You GROW your own subtree, choosing the child's ROLE by the scope you hand
+ down: a coherent SUB-domain that is itself an area — large enough to be
+ decomposed further and owned end to end — gets a child `owner`; a single
+ function or lane gets a `manager`. Spawn either with `agents_spawn_peer` (it
+ takes a required `role` — which SYSTEM prompt the child boots on — and a
+ `persona`, its stable working context; torn down with `agents_despawn_peer`
+ when the child's scope closes). A child `owner` grows its own subtree the same
+ way, so owner tiers stack to whatever depth your domain warrants.
+- You are a COORDINATOR, not a typist. You decompose your domain and delegate:
+ child `owner`s drive their sub-domains, child `manager`s drive the lanes, and
+ you may brief SUBAGENTS directly for area-scoped work that does not warrant a
+ standing child. You never hand-write code.
+- SUBAGENTS ARE NOT MESH NODES. A subagent is an in-process worker, not a peer:
+ it has no Compass handle, account, or channel, and holds no Compass comms
+ tools. You steer it over OMP-internal IRC and follow-up turns; its work

+ work is lost.
+- Name each child for what it DOES, not the tool it uses (the name-by-function
+ tenet, `skill://management-trees`). Role sets capability; the name states the

+## How you communicate (async, never in-session)
+- The operator never prompts you directly. Every human<->Manager and

+# Agent roles: supervisor, owner, manager
+
+Every standing node in a Compass tree is a **Manager agent**, and every one of
+them carries a **role** that sets what it does. There are exactly three:
+
+- **`supervisor`** — owns the whole tree. It is the operator's first point of
+ contact, routes incoming issues down to the owning subtree rather than working
+ them, is the default target for alerts and incidents, and carries top-down
+ broadcasts for the whole tree. It grows and owns the project subtrees. There is
+ always exactly one at the root (see [management trees](../../config/skills/management-trees/SKILL.md)).
+- **`owner`** — owns one product, service, or domain end to end. It decomposes
+ its area into per-function lanes and coherent sub-domains, delegating a lane to
+ a child `manager` and a sub-domain to a child `owner` (owner tiers nest as deep
+ as the domain needs), aggregates status and PRs back up, and grows its own
+ subtree. The mid-tier.
+- **`manager`** — owns one lane and drives it to done. The leaf: it is assigned
+ issues, holds them end to end, ships stacked PRs through the review loop, and
+ stops only when blocked on human input.
+
+The roles form a hierarchy of scope — tree, domain, lane — but they are not a
+chain of command distinct from the tree itself: an agent's parent and children
+are a model fact (its `parent_agent_id`), and the role names what that node is
+responsible for at its place in the tree.
+
+## A role selects a block-0 prompt
+
+A role is not a flag the agent reads and interprets — it selects the agent's
+**system prompt**. Each role has a prompt at `prompts//SYSTEM.md`, and the
+role a node is spawned with picks which one is injected as its block-0
+`customSystemPrompt`, **replacing** the default. The prompt *is* the role's
+capability and posture; there is no second place the role's behavior lives. This
+is orthogonal to **persona**, which *appends* stable working context (the repos,
+projects, and lanes a node owns) rather than replacing the block-0 posture — so a
+node's identity is its role prompt (replace) plus its persona (append). See
+[persona](persona.md).
+
+## Role is not name
+
+A role sets a node's capability, model, and tools; a node's **name** states its
+**function** — what team or department it is. The two compose and do not
+collide: an `owner` might be the *Payments* owner and a `manager` the *CI*
+manager. Name a node for what it does, never for the tool it reaches for (an
+`aws` or `stripe` node is the anti-pattern) — the function is stable, the tools
+are an implementation detail. The naming tenet and example tree shapes are in
+[management trees](../../config/skills/management-trees/SKILL.md).
+
+## Workers are not a role — they are subagents
+
+There is deliberately **no `worker` role**, and no tree node per implementation
+hand. Implementation is done by **subagents**: in-process workers a Manager
+briefs and dispatches inside its own session. Minting a tree node per worker
+would cost a durable account handle and a per-agent container each — untenable
+for workers that are numerous and short-scoped, whereas a subagent rides its
+Manager's existing session and container at zero marginal cost. A subagent is
+not a peer on the mesh, and this is **structural, not a prompting convention** —
+the same way the [comms model](comms-model.md) keeps work and conversation on
+separate surfaces by construction:
+
+- A subagent has **no Compass handle or account** — it is not addressable, it
+ cannot be spawned as or reparented into a tree node.
+- A subagent holds **no Compass comms tools** — it cannot post to a channel, so
+ it cannot reach the operator or another Manager. The operator has no channel to
+ a worker and redirects one by pinging the Manager that owns it.
+- A subagent has **neither comms surface**: no channel *and* no session log of
+ its own on the mesh. Its work lives entirely inside its Manager's session log,
+ nested under it.
+
+Because a worker holds no comms tools and no handle, all user-facing and
+cross-node traffic necessarily routes through Managers — comms centralization is
+enforced by what a subagent structurally *is*, not by asking it to behave. That
+is why "worker" is a lifecycle stage inside a Manager's session, not a rung in
+the tree.
