Summary

Resolves merge conflicts for community PR #155 by rebasing onto current main and applying @ded-furby's two sharper boundary statements to the consolidated LIMITATIONS.md:

  1. Evidence boundary — HMAC claim now includes assuming that key remains protected.
  2. Tool-governance boundary — Talon does not prevent the same tool from being invoked on a separate path that does not pass through Talon.

The full alternate LIMITATIONS.md from #155 is superseded by the version already on main; this PR lands only the net-new clarifications with Co-authored-by: ded-furby.

Closes #117 when merged. After merge, we will close #155 with a pointer here.

Test plan

Note

Low Risk
Documentation-only edits to capability boundaries; no code, auth, or data-path changes.

Overview
LIMITATIONS.md picks up two boundary clarifications from community PR #155 (merged into the current doc on main):

The evidence boundary now states that HMAC integrity holds only assuming the signing key remains protected, not unconditionally after signing.

The tool-governance boundary adds that Talon cannot block the same tool if it is invoked outside the gateway path.

No runtime or policy code changes—documentation and claim discipline only.

Rebase PR #155 onto current main: keep the consolidated LIMITATIONS.md
structure and add the two sharper boundary statements from @ded-furby:
signing-key custody in the HMAC claim and tool invocation outside the
governed path.
