+# Tool State Contract Tests Validation
+
+PR: PR_26152_068-tool-state-contract-tests
+
+Date: 2026-06-02
+
+## Scope
+
+Added a reusable Tool State contract with validation fixtures and targeted tests.
+
+No database implementation, authentication implementation, UI/page changes, CSS changes, HTML changes, or dependency changes were made.
+
+## Files Validated
+
+- `src/shared/contracts/toolStateContract.js`
+- `tests/fixtures/tool-states/tool-state-scenarios.json`
+- `tests/shared/ToolStateContract.test.mjs`
+- `src/shared/contracts/identityPermissionsContract.js`
+- `tests/shared/IdentityPermissionsContract.test.mjs`
+- `src/shared/contracts/projectContract.js`
+- `tests/shared/ProjectContract.test.mjs`
+
+## Validation Lanes
+
+- Lanes executed: contract - tool state ownership, project binding, type, visibility, version, status, edit policy, asset refs, and portable export validation.
+- Compatibility executed: identity permissions contract and project contract - confirms Tool State uses the approved identity/project contract vocabulary.
+- Lanes skipped: runtime, integration, engine, samples, recovery/UAT - this PR does not change runtime behavior, handoff contracts, engine code, samples, or UAT surfaces.
+- Samples decision: SKIP because this PR does not touch samples or sample JSON.
+- Playwright impacted: No. This PR adds shared contract data, fixtures, and targeted node tests only.
