messages. The Slack interaction records an authorization decision; the agent
performs any subsequent action through its configured integration.

Tool-approval cards link to **Review request in Sanction** and explain that full
arguments are not shown in the channel. A signed-in wallet admin opens the linked
request and selects **Review exact request** to decrypt it. Slack membership alone
does not grant access to that view. The existing Slack Approve/Deny buttons remain
available; review is guidance, not a new enforced prerequisite.

Cover the non-tool presentation branch.

The test covers only tool-shaped inputs. A regression that adds the tool label or context block to a non-tool event would pass. Add a non-tool case and assert "Review in Sanction" plus no context block.

The cited deny-path instruction applies to authorization decisions. This change affects presentation only. The decryptMock assertion is already wired and can detect decryption added to either payload builder.

Review comment at @tests/delivery.test.ts around lines 36 - 56:
Add a non-tool event case to the “Slack exact-request review handoff” tests in
`tests/delivery.test.ts`, covering both `slackPayload` and
`slackInteractivePayload`. Assert that the review button says “Review in
Sanction” and that neither payload contains a context block; retain the existing
`decryptMock` assertion.

After applying the fix, consider running `coderabbit review --agent` for local
review. Visit https://docs.coderabbit.ai/cli?utm_source=ghpr
