 - **78 API/OpenAPI tests passed** in fresh PostgreSQL (`parity_review_31`): 51 assembled-server actual-auth scenarios and 27 API contracts. Log: `/tmp/parity-test-final-full.log`. Final server typecheck/build and map validation passed (`/tmp/parity-test-final-types.log`, `/tmp/parity-test-final-build.log`, `/tmp/parity-test-final-maps.log`). These replace the earlier 71-test snapshot; no full local test-sweep pass is claimed.
 - Companion review also found that token refresh advances `grant.updatedAt` and can erase a saved pending Google service selection. Both new component cases failed before the fix (`/tmp/parity-google-refresh-ui-red.log`). Successful direct/cloud consent now records additive `providerTenant.oauth.consentedAt` metadata; refresh preserves it. The picker compares the pending request against that consent timestamp, using grant creation for legacy metadata rather than treating refresh as new consent.
 - **10 focused Google/OAuth tests passed**: eight service-picker cases (including newer/older consent and refresh/legacy behavior) plus two real local-HTTP OAuth protocol cases proving that successful consent is timestamped and concurrent token refresh preserves it. Log: `/tmp/parity-google-refresh-green.log`. The protocol fixture uses its existing board actor injection and does not count as actual-auth agent evidence. JSON metadata is additive; normal migration generation validates that no SQL change is required.

+### 2026-10-26: preserve policy and explicit-grant tool access
+
+The review of `70b7c973c8` correctly identified that requiring a caller profile rejects legitimate access through an allow policy or explicit scoped `tools:use` grant. Both actual run-JWT cases failed before the correction (`/tmp/parity-caller-grants-red.log`). The caller's full access decision remains intersected with the target's decision; the narrower profile-only precondition is removed. The negative case now uses a caller-specific Block policy with the target still permitted, proving that another target cannot bypass the caller's actual action restriction. Default broad `tools:use` remains governed by the ordinary evaluator rather than being reinterpreted by this API.
+
+A further real-JWT regression found that the `authKind: none` shortcut could skip comparison of dedicated grant identities (`/tmp/parity-credential-kind-red.log`). Credential identity comparison now applies for every auth label. Both API-key and no-auth-labelled dedicated grants deny before provider invocation when their identities differ. The same responsible-user and target authority, approval, revocation, and rate checks remain in force.
+
+Implementation `52a87697f0` passed **81 API/OpenAPI tests** (54 assembled-server actual-auth scenarios plus 27 contracts) in fresh PostgreSQL `parity_review_33`, log `/tmp/parity-caller-grants-full-green.log`. The earlier profile-only version is superseded by this evidence; its failures and recovery remain above. Final server typecheck and build passed (`/tmp/parity-caller-grants-final-types.log`, `/tmp/parity-caller-grants-final-build.log`). The earlier 18-case focused run passed before adding the no-auth-label regression (`/tmp/parity-caller-grants-green.log`); the final full suite includes all 19 delegated-test cases. Google consent, GitHub UI, and Copilot code are unchanged by this correction.
