# Source/model inspection and native construction

Clean public development source `2392641d5c218604288997d69ef9536bf80e30b4`,
branch agent/body-context-model-preflight, Go 1.27.2.

The TDD red log records the unsupported CLI flag before implementation.
The full CLI/bodycodegen race suites passed in 134.340s/33.900s. Actual clean-binary
inspection returns READY_FOR_RANKING with zero predictions and zero candidate tests.
Its graph-context SHA matches actual subsequent own-model assembly. That assembly
makes one call and passes 12/12 authored fields; its different native inputs pass
4/4. Saved replay passes 4/4 and makes zero new calls.

The existing own QAT model was used without training or downloads. Training exposure
of native cases is unknown. These finite examples do not measure general accuracy
or a speed advantage. Inspection verifies local files and source representation,
prepares/typechecks alternatives and does not perform candidate scoring.

This source is separate from installed 0.6.20 and release21 preparation. Public
branch access is not merged/released status. See the wiki Source-and-Model-Preflight
page and exact-source command documentation for current scope.
