…heck actually deny (#189) Two decorative controls made real: - #15/#31 — emitScopedTelemetry now writes a TAMPER-EVIDENT chain: each event links to the previous (prevHash→hash via audit-chain.hashRecord) and the head is Ed25519-signed with the device key (chain-head.sig). And it ALWAYS writes (dropped the !scopedConfigured early-return) so governance evidence exists by default, not only once a policy is set. Verified: 2nd.prevHash == 1st.hash, head.sig present. - #18 — grantCheck stopped hardcoding result:{valid:true}. New revocation ledger (revokeGrant/unrevokeGrant, persisted) + checkToolGrant() verdict; mcp callTool now GATES on it (a revoked server:tool is blocked before dispatch with an isError result), and emitToolGrantCheck records the real verdict. Backend + frontend 0. Co-authored-by: Michael Heller <YOUR_COMMIT_EMAIL> Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com>

Summary
Adds pinned contract-sync automation for Noetica's vendored SourceOS interaction TypeScript artifact.
This PR adds:
scripts/sync-sourceos-contracts.mjs.github/workflows/sourceos-contract-sync.ymlBehavior
The sync script fetches
generated/typescript/sourceos-interaction-event.tsfrom the pinnedSourceOS-Linux/sourceos-speccommit and normalizes the local header. It supports:--checkfails when the vendored contract drifts from the pinned upstream artifact.Boundary posture
No runtime behavior changes. Noetica remains the browser chat/model/steering UX surface. This only prevents silent contract drift.
