Boundaries respected

• NOT pushed. NOT merged elsewhere. NOT tagged. NOT deployed.
• main is local-only (no git remote configured) — push is not possible and was not attempted.
• No existing file modified — package is purely additive.
• v0.4 / v0.5 / orchestrator code untouched.
• No production DB write, no DDL execution, no execution_enabled change.

Cleanup needed

None. Working tree is clean; all new artifacts are committed; no temp/scratch files were left in the repo or in production paths.

Reversal (NOT executed)

git reset --hard f111d4a on main fully reverses this macro.
