 ## Unreleased
 
+### Changed
+- **`biolink-model` is bumped to 4.4.6 and the grant it absorbed is dropped.** Unlike the 4.4.5 wheel, whose bundled schema still carried the 4.4.4 version string, the 4.4.6 wheel's schema registers as 4.4.6, so `BIOLINK_VERSION` now reports the pinned version accurately. The release also attached `population_context_qualifier` to `EntityToDiseaseAssociation` / `EntityToPhenotypicFeatureAssociation`, so the `CLASS_FIELD_OVERRIDES` tripwire removed that grant from both classes (the removed entries stay in the source as commented examples for future grants); the remaining deliberate grants are `temporal_context_qualifier` on both classes plus `sex_qualifier` on `EntityToDiseaseAssociation`, and `prune_to_class` now keeps `population_context_qualifier` natively on the whole disease/phenotype family, including previously ungranted classes.
+
 ### Added
 - **`validate-infores` checks every emitted knowledge-source identifier against the Translator registry.** The new command classifies each `infores:` CURIE on the edges (`primary_knowledge_source`, `sources[].resource_id`, `sources[].upstream_resource_ids`), the nodes (`provided_by`), and optionally the RIG document against `biolink/information-resource-registry`'s `infores_catalog.yaml` -- the authoritative catalog translator-ingests' SOP points at but never checks programmatically. The registry ships as a bundled offline snapshot (vendored from upstream commit `a72dbc3b55d5`), `--registry refresh` fetches the live catalog through the bounded-retry network layer, and `--registry off` reports structure only. The default posture is advisory (exit 0 with warnings) because Tablassert legitimately mints graph-local CURIEs; repeatable `--allow-infores` exempts them and `--strict` makes unregistered CURIEs fail in CI. Values without the `infores:` prefix are malformed, not unregistered. This closes the validation gap that only the CURIE prefix was ever checked.

 Annotation names fall into three groups at build time:
 
-- **Allowed edge fields:** names on the edge allow-list: [Biolink Association](https://biolink.github.io/biolink-model/) slots, qualifier slots, and curated KGX/Tablassert edge fields (e.g. `p_value`, `adjusted_p_value`, `knowledge_level`, `supporting_text`, `publications`, `effect_size`, `effect_type`, `statistical_significance_qualifier`, qualifier slots like `severity_qualifier` / `disease_context_qualifier`) are written to edges verbatim. `effect_size` and `effect_type` became real Association slots in biolink-model 4.4.4 (PR #1774) and emit as real JSON numbers and enum tokens. Annotation names are matched case-insensitively against the allow-list and emitted under the canonical slot spelling. `regulatory_approvals` (multivalued, so declare [`split_by`](#split_by) for pipe-joined cells like `011111|022222`), `disease_context_qualifier`, `anatomical_context_qualifier`, and `frequency_qualifier` are declared natively on `EntityToDiseaseAssociation` / `EntityToPhenotypicFeatureAssociation` by biolink-model 4.4.5, and `sex_qualifier` on the phenotypic-feature class, so those rows keep them without any override. The remaining class-scoped grants cover DAKP's sparse qualifier stack ahead of the model: `population_context_qualifier` and `temporal_context_qualifier` on both classes, plus `sex_qualifier` on `EntityToDiseaseAssociation`; without a grant `prune_to_class` nulls those qualifiers off the pinned rows. `species_context_qualifier` stays disabled, and `temporal_interval_qualifier` / `severity_qualifier` stay unsatisfiable, so none of the three is granted.

 - **Study metadata:** `study_size`, `study_cohort`, `study_context`, `study_date_range`, `study_method_description`, and `study_method_types` are current Biolink `Study` node properties ([biolink-model PR #1770](https://github.com/biolink/biolink-model/pull/1770)). They describe the study itself, not an association, so their values are carried on the edge's **inlined supporting Study** (`has_supporting_studies` to `Study`, the COHD/ICEES pattern) rather than emitted as edge fields. Deprecated `supporting_study_*` spellings and `sample_size` are accepted as aliases and renamed onto canonical `study_*` names by coercion. They never appear in final JSON. Declaring any of them is legal and emits a `BiolinkRelocationWarning` naming where the value went.
 - **Unsatisfiable slots:** names the Biolink LinkML schema declares but attaches to **no** Pydantic class, derived from the installed `biolink-model`. A record carrying one could never validate, so its value is preserved in the inlined supporting study's `StudyResult.description`. A slot leaves the set automatically once a release attaches it.
