I read this as implementation - I’ll execute the compatibility and installed-artifact lane in the specified worktree, verify it, clean temporary assets, and produce the required evidence.


I read this as implementation verification - the compatibility suite and source-mode driver are green; I’m now building isolated wheels and exercising the installed runtime boundary.


I read this as verification - both source and isolated installed-wheel drivers now emit the required PASS payload; I’m running the focused regression and strict static gates before cleanup.


I read this as test-environment diagnosis - the broad gateway command used the global pytest without pytest-asyncio, so its async failures are environmental; I’m rerunning the same focused suite with the repository venv that provides the declared test plugin.


I read this as implementation completion - the compatibility lane is complete and verified.

DoneClaim: DONE.

- Added synthetic v1/current compatibility coverage and runtime-root-bound smoke driver.
- Source and installed-wheel drivers emitted required PASS payloads with zero network/Telegram sends.
- Focused gateway suite: 113 passed; profile suite: 19 passed.
- LSP, Ruff, ty, basedpyright, and compile checks passed.
- Temporary wheels, venv, fixtures, driver, and build staging were removed and verified absent.
