The contract check ran as an Ansible task in the middle of every provider deploy, and the two client checks ran the same way. A test that is part of the deploy cannot be run without deploying, cannot be re-run on its own, and reports its verdict as a deploy failure. Twenty-seven task files lose 491 lines to this.
It is now what it always was. Each provider ships files/test/test.sh, templates/test.env.j2 and meta/tests.yml, and test-e2e-cli stages one shared harness beside it: run.sh drives contract.sh in a throwaway container on the provider's own network, then isolation.sh for adapter-fronted providers. The read probe each provider offers moved from the calling task into meta/mcp.yml next to the allowlist it must satisfy, and the schema now rejects a read probe naming a tool outside that allowlist.
The bearer the test presents is the one a client resolves through mcp.credential, via the new mcp_client_bearer lookup over resolve_credential, which moved to utils.roles.applications.mcp so it is the same function mcp_servers renders every client connection with. The probe presented whatever the calling role passed, which for the fifteen adapter-fronted providers is a different secret than any client holds.
Sidecar isolation is read from the engine rather than measured inside the container, so it no longer needs a delegation to the node holding the task: attachment is compared by network name, which drops the gwbridge special case, and a swarm worker says it cannot measure instead of skipping silently.
Retrying is bounded by wall clock against MCP_DEADLINE_SECONDS, which scales through the same lookup('timeout') as the harness budget it has to stay under. A flag that is neither true nor false aborts rather than reading as off.
mcp-provider-probe becomes mcp-provider-cli-test: an enabled provider must ship the test rather than include the task. mcp-probe-bearer becomes mcp-adapter-bearer, tying ADAPTER_BEARER to the declared credential key now that no probe include carries it. A new integration test renders the shared env template for every provider through Ansible's own templar, so a later change to it breaks visibly instead of poisoning twenty deploys quietly.
Hermes and OpenClaw keep their client-side proof as CLI tests of their own.

The adapter flush notifies `compose up --force-recreate`, which recreates
every service in the project including the Jenkins controller. The contract
probe then ran 12 seconds after that recreate, while Jenkins was still
booting, so the upstream answered 401 and the probe reported the adapter as
refusing its own credential.
Extract the readiness wait so it can run twice and repeat it after the
flush. Bind the adapter to the controller with service_healthy as well:
that is what keeps gitea's sidecar out of this race, and swarm ignores the
condition, so the wait carries that mode.

The controller serves its MCP plugin endpoint to anonymous callers: the
deploy probe measured a 200, and the response carried the base64 of
'anonymous' in its reporting endpoint. The JCasC authorization strategy
grants anonymous nothing, so the plugin does not hang off it.
Front it with the svc-ai-mcp-adapter instance. Clients present mcp_bearer
to compose service jenkinsmcp and get a 401 otherwise; the adapter
presents the controller's own API token upstream over HTTP Basic.
Narrow the allowlist to the 15 read-only tools and record the 19 the
plugin serves as upstream_serves. The four write tools were advertised
while mutating_tools_enabled stayed false, so the adapter would have
refused them at call time: a dead surface a green deploy hides.

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.
