Policy engine pins agent-control-spec 0.4.0-alpha.4, deprecates REMOVED_MANIFEST_FIELDS

By RepoJournal · Filed · About Agent Security · Composed from the cited sources · methodology

The agent-governance-toolkit moved to agent-control-spec 0.4.0-alpha.4 and corrected the manifest fields its engine rejects, while the TypeScript 7 migration advanced scanner work first.

feat(policy-engine): upgrade ACS and clarify upstream ownership microsoft/agent-governance-toolkit

by liamcrumm

AGT now pins agent-control-spec to =0.4.0-alpha.4 while keeping agent-hooks-sdk at 0.1.0-alpha.5 and the existing host APIs unchanged. Previously the compatibility layer rejected URL sources that alpha.4 implements and could not pass download limits to the bundled dispatcher, so if you configure policy sources by URL, that path now works instead of being refused.

fix(policy-engine): record alpha.4 follow-ups from the ACS upgrade review (#4272) microsoft/agent-governance-toolkit

chore(typescript): upgrade three packages to TypeScript 7 microsoft/agent-governance-toolkit

by Ricky-G

TypeScript moves to 7.0.2 across the SDK, Copilot extension, and MCP server without dropping test typechecking or ESLint compatibility.

fix(supply-chain): verify npm aliases for TypeScript 7 migration microsoft/agent-governance-toolkit

by Ricky-G

The strict supply-chain scanners now verify canonical registry identities for the approved TypeScript 7 compiler and TypeScript 6 API npm aliases, which were previously queried as nonexistent packages while node_modules/typescript resolves to @typescript/typescript6. It is a scanner-only change that touches no dependency manifests or lockfiles.
