Summary

Add 16 Behave BDD scenarios covering the router-facing runtime.Executor API, increasing code coverage from 94.66% to 96.94% (214 fewer uncovered lines).

What is covered

create_executor() factory function and Executor initialization
Executor.execute() dispatch to LLM, graph, tool, and multi-actor agents
_execute_llm() credential injection (provider-specific + openai_compatible fallback) and error handling
_execute_graph() PureGraphConfig construction from route definitions
_execute_tool() tool configuration from config blocks
_execute_multi_actor() routing with default_actor resolution and empty-actor error
_build_factory_config() credential and limit injection into agent configs
_estimate_tokens() with tiktoken and heuristic fallback
NodeUsage and ActorResult dataclass field storage

Verification

nox -s unit_tests → 1838 scenarios, 0 failed
nox -s coverage_report → 96.94% (passes 96.5% threshold)
nox -s lint → all checks passed
nox -s typecheck → 0 errors
nox -s security_scan → 0 findings
nox -s dead_code → clean

Closes #33

Thanks for the thorough review, Brent. Here is my response to each comment:

1. Review 9484 — "expected reply" mismatch

Fixed. The step description has been updated from "the ActorResult response should contain the expected reply" to "the ActorResult response should be non-empty." The assertion checks len(context.test_result.response) > 0, which accurately verifies that a non-empty reply was produced by the mocked LLM agent. The name now matches the code.

2. Review 9485 — "injected api key" assertion

Fixed. The step now verifies that the executor's credentials dictionary contains the OpenAPI API key "sk-test-injected" rather than just checking test_result is not None. The assertion chain now confirms: the result exists, the executor exists, credentials exist, the openai key is present, and its api_key value matches the injected key.

3. Review 9486 — Invalid graph route config (step_config_graph_route)

Fixed. The nodes list now includes {"id": "end", "type": "end"} alongside the existing start node, so the exit_nodes: ["end"] reference resolves correctly. The config dict now represents a valid trivial graph with a start-to-end structure.

4. Review 9487 — Same issue in step_config_graph_openai

Fixed identically to #9486. The step_config_graph_openai route now also includes the end node in its nodes list.

5. Review 9488 — Type field in actors_no_type config

Not changed. The step description says "a config dict with actors key but no type field" — this correctly refers to the top-level config dict, which has actors, name, and cleveragents keys but no type field at the top level. The "type": "llm" inside actors.default is the sub-actor's own type, which is required and correct for the sub-actor config within a multi-actor bundle. The test is doing exactly what its description says.

6. Review 9489 — Node prefix assertion

Fixed. The assertion has been changed from "." in node.node_id or node.node_id.startswith("default") to node.node_id.startswith("default."). This correctly verifies that node IDs are prefixed with the default actor name followed by a dot separator, matching the step description.

All changes verified with:

nox -s unit_tests — 1838 scenarios, 0 failures
nox -s lint — all checks passed
nox -s format -- --check — all files already formatted

Thanks for the thorough review, Brent. Here is my response to each comment: **1. Review 9484 — "expected reply" mismatch** Fixed.
