Exact-head audit found the original domain/boolean selector was a hand-authored model-selection heuristic. Commit Verified locally:
This remains a draft stacked on #899; no protected-main or runtime-scoring claim. |
Merge the current #899 ownership-boundary head into the dichotomous measurement-policy stack without rewriting child history. The parent delta is the code-current Vision runtime note; the measurement policy delta remains unchanged.
Merge the current #899 root after it incorporated protected main@3f61c824. The only new parent delta is docs/index.md; the dichotomous measurement-policy semantic delta is unchanged.

A bounded child provenance implementation is now stacked on this exact measurement-policy head: #915 ( |

Parent #899 has moved non-force to e5711282… after adopting protected-main Draft-admission workflow contracts. This child’s seven measurement-policy files do not overlap those parent repairs, so retaining the old parent ancestry is now a wrong-base finding. Preserve the measurement-policy delta exactly, adopt the four parent workflow/contract blobs, and advance this branch with a two-parent non-force convergence commit. Do not transfer predecessor checks or approval.

In `@CHANGELOG.d/dichotomous-measurement-policy.md`:
- Line 3: Changelog claims for DRAFT/PILOT scoreless enforcement that the
implementation does not guarantee. Either implement lifecycle-aware validation
and scoring behavior for InstrumentMeasurementPolicy so DRAFT/PILOT observations
remain scoreless and PUBLISHED activation evidence is validated appropriately,
or narrow the changelog entry to the enforced published-instrument reference
requirement.

Stack authority update: parent #899 moved to |
This branch has not been deployed

Scope
Adds the LineageWeave-owned dichotomous measurement-policy contract. LineageWeave owns rubric/version/lifecycle/activation and observation-policy semantics only. Numerical IRT kernels remain in fast-mlsirm, temporal/event/multilevel measurement semantics remain in TEPP, and provider/judge execution remains in contextual-orchestrator.
