test(replan): align machine cadence default expectation

[mikamikasuki]

Goal and Delivered Outcome

The machine-configuration API test expected completed_todos for the todo_replan_cadence_machine_defaults_v1 template. On canonical main, the namespace’s documented product default is five effective_turns, so the assertion fails even though the configuration source and documentation agree.

This changes the fixture expectation to effective_turns, keeping the API contract regression aligned with the current default.

• Outcome basis: current product default and machine configuration contract.
• Observable before → after: the inspection test fails on canonical main due to the stale completed_todos expectation; it passes when asserting the documented effective_turns default.
• Issue/task and intended base: self-contained test maintenance; base main at 3ed5d6bc88ffaaa05f2b1bc6a98ed5d921379fd1.

Author Declaration

• Written by: model_agent — OpenAI GPT-6 Luna Medium.

Implemented against

• Specification and revision: docs/quota-allocation.md and loopx/capabilities/todo_replan_cadence/machine_defaults.py at 3ed5d6bc88ffaaa05f2b1bc6a98ed5d921379fd1.

Criterion	Disposition	Symbol / path	Test or command
The v1 machine default reports five effective Turns	implemented	tests/test_chat_machine_configuration_api.py	test_inspection_lists_registered_namespaces_without_local_refs

• Self-check before submission: reproduced the stale assertion failure on exact main, checked the machine-default implementation and its documented contract, and confirmed the diff changes only that expectation.

Scope And Continuation

• Completed scope: aligned the machine-configuration inspection test with the current default; no runtime behavior changed.
• Slice boundary / successor: complete within this scope.

Validation

• Tested revision: 899fe83ed7883106c45af4b6649072d530decfd9 (base 3ed5d6bc88ffaaa05f2b1bc6a98ed5d921379fd1)
• Run state: finished
• Input classes: synthetic

Check kind	Result	Public-safe evidence / limitation
regression_parity	passed	The affected assertion fails on exact main because actual count_unit is effective_turns while expected is completed_todos; the updated focused test passes on this head.
unit	passed	tests/test_chat_machine_configuration_api.py: 14 passed.
static	passed	Ruff for the changed test and git diff --check passed.

• Coverage and gaps: the changed surface is a single API-template expectation. The full repository suite was not run.

Frontend / Visual Evidence

• UI impact: none
• Before: N/A
• After: N/A
• States and viewports shown: N/A
• Source data: synthetic
• Attention review: not applicable; no user interface changed.

Type of Change

• Test update

LoopX Area

• Control plane (goals, todos, quota, scheduler, registry, runtime)

Technical Direction

• N/A; this updates a test expectation to the current product default.

Shared-authority RFC fixture impact

• N/A; no authority schema or runtime contract changed.

Boundary Checklist

• No private state, credentials, raw traces, internal links or local paths are included.
• No maintainer-owned benchmark work is duplicated.
• Scope is limited to the machine-configuration default assertion.
• UI impact is marked none.
• The commit includes a DCO Signed-off-by trailer.

Closing in favor of #5980, which already includes this exact effective_turns expectation change and the related exact-Todo fixture correction.
