The group map is built by looping over the discovered MCP servers, so an
empty list left the variable undefined and the next task aborted. That
list became reachable-empty once discovery narrowed to the providers a
run actually deploys.
The consuming tasks move into their own file behind one condition rather
than taking a default, because an empty result is a different case and
not a missing value: defaulting it would reconcile the existing grants
against nothing and drop them.
Every MCP role keeps its task tree under tasks/utils/ without numeric
prefixes, so a caller can reach any of them through include_role
tasks_from. utils/roles/mapping.py holds that path as the single source.
Ansible resolves a relative include against the including file's own
directory when that file was reached by path, but against tasks/ when it
was reached through tasks_from. The same file therefore loaded from its
own role and failed from a caller using tasks_from. Every nested include
now names {{ role_path }}/tasks/utils/..., which holds under both bases,
and a lint walks each tasks_from entrypoint transitively to keep it so.
The exec-gating lint learns the same form, otherwise it loses the include
chain and reports inherited IS_STACK_HOST gates as missing.
The expression resolving a provider's stored token appeared eighteen
times. plugins/lookup/mcp_credential.py replaces it, and mcp_probe_owner
disappears from eight roles: it was only ever a step towards the bearer
and no probe read it.
The Hermes and OpenClaw probes stop aborting the play while it is still
running. Roles deploy in dependency order, so a client probing during its
own role can run before a provider exists at all, and failing there
prevents that provider from ever deploying. The verdict moves to the
reconciliation pass, gated on MCP_RECONCILE_STRICT, which the reconciler
sets and group_vars declares so the readers need no default.
The sys-svc-mcp-reconcile role is added here; wiring it into a stage is a
separate change.
