security(workforce-validation): authorize component-evidence resolution before owner reads #414

Finding

Fresh review of canonical PR #235 found that corroborate_final_weight_component_evidence(...) originally performed native component-owner reads without executing a purpose-bound authorization decision at this application boundary. Possession of final-weight/binding evidence is not reusable authorization.

The repaired boundary requires exact ValidationPrincipal, PurposeBoundAccessPolicy, and purpose_code, authorizes before the first owner read, binds the audit resource to the exact final analysis-weight receipt, and requests only component projection fields actually consumed.

Ordinary-forward repair

• 8be428ddd7c0a6efbc22e1eb1795441b581913aa → 9b19ae464d32b5d8863552a443cfa7551eafe89c — test-only hypothesis/restoration confirming the deliberately composite FinalWeightComponentEvidenceReadPort remains API truth.

#416 is an additive refinement rather than a replacement of #414. Fresh review showed tenant_record_id and validity_study_id were consumed from native component projections by _require_component_scope(...) but omitted from the authorized field sets. b4145493988bee3dd869bc7d6688f6fbe7278235 adds the zero-owner-read denial regression when either scope field is missing; 4ec16e61f40265675df0e8464d4ee2bd314fcca3 adds both coordinates to _BASE_READ_FIELDS and _ADJUSTMENT_READ_FIELDS. #414 minimization remains intact because base-only paths still do not request adjustment-only transform fields.

Current canonical source head is 4ec16e61f40265675df0e8464d4ee2bd314fcca3. All source evidence remains non-hosted until exact-head acceptance completes.

Required contract

• authorization precedes every native component owner read;
• the audit target is final_weight_component_evidence_resolution:<analysis-weight receipt tail>;
• requested fields include every native projection coordinate the corroborator consumes, including tenant_record_id and validity_study_id;
• base-only lineage requests no adjustment-only transform fields;
• adjustment-only fields are requested only when a governed specialized component is actually read;
• denied purpose/tenant/scope/consumed-field leaves owner-read counts at zero;
• the composite FinalWeightComponentEvidenceReadPort contract remains unchanged;
• science(workforce-validation): bind final-weight lineage to exact typed component receipts #411/security(workforce-validation): bind component projections to tenant and validity-study authority #412 exact receipt identity, native-owner scope provenance, construction chronology and governed-use currentness remain intact;
• security(workforce-validation): prevent public forging of corroborated component resolutions #413/security(workforce-validation): close tuple.__new__ bypass on component-resolution issuance #415 proof-result issuance integrity remains intact;
• durable feat(workforce-validation): adopt registry into owner persistence #248 adoption must preserve authorization-before-read, exact receipt targeting, field minimization and complete authorization of consumed scope fields.

Completion boundary

Do not close for source repair alone. Completion requires current exact-head owned test/docstring/edge evidence, installed-wheel/package/PostgreSQL/security gates, qualifying independent review, normal protected integration, and durable #248 (or verified successor) adoption after the parent becomes protected truth.
