Plan: plans/traust-standardization/0-continuous-ops/11-shaun-spend-sources-spike.md (part)

Plan 11, Revised (2026-10-27), step A (engine half). Core: traust-security/traust-core#230. traust follows.

What changed

• The runner already parses a command's last stdout line as a JobResult and passes it to OpsService.complete. Core's JobResult now carries usage, so a session's measured usage reaches complete with no runner change. Admission and the controller are untouched.
• traust-engine <op> --models <model-registry.yaml> (a common flag, next to --feeds) registers core's model catalog, so a completed order's usage is priced as its spend. Without the flag the order still completes, and core records the gap as spend-unpriced in the run manifest.
• The core pin is moved to traust-core#230's head (603aabf): [tool.uv.sources] rev, with uv lock.

Parity

Behaviour	Home
a command's JobResult completes its order	unchanged (runner.outcome → ops.complete); it now carries usage
pricing	core ModelCatalog, registered by --models

Legacy files

None.

Behaviour changes

Before	After	Why
claim and record never recorded spend	with --models, an order whose command answers its usage gets priced spend in the same transaction as its completion; without it, the order completes and the gap is in its manifest	plan 11 step A

Changed tests

None (one new parametrized test in tests/test_ops_runner.py).

• A person reviewed each changed test and the behaviour change is intended

Tests

• test_a_session_that_answers_its_usage_settles_it_as_the_orders_spend[priced | no registry]: traust-engine claim end to end on SQLite. Reply text is followed by a JobResult carrying usage; the test checks spend in the order's lane at the registry price, or the order completed with the gap in its run manifest.
• uv run pytest tests -n auto: 1326 passed, 26 skipped.

Net LOC

src +7 (net +7); tests +46; pin and lock ±5.

Supervisor sign-off (on Shaun's behalf, autonomous review loop). Plan 11 A (part): the runner already passes the session's last-line JobResult (now carrying usage) to complete; adds --models <model-registry.yaml> so engine runs can price spend. Admission and controller untouched. Supervisor merged development and re-pinned core to efd2797 (core#230); CI green.
