Two small follow-ups to the PR #2433 → #2436 → #2439 incident chain.
1) `import inbox # noqa: F401` in workspace/a2a_mcp_server.py was
misleading — `inbox` IS used (at the bridge wiring inside main()).
F401 means "imported but unused", which would mask a real future
F401 if the usage is removed. Drop the noqa, keep the explanatory
block comment about the rewriter's `import X` → `import mr.X as X`
expansion (and the `import X as Y` → `import mr.X as X as Y` trap
the comment exists to prevent re-introducing).
2) scripts/test_build_runtime_package.py — 17 unit tests covering
`rewrite_imports()` and `build_import_rewriter()` in
scripts/build_runtime_package.py. Until now the function had zero
coverage despite the entire wheel build depending on it. Tests
pin: bare-import aliasing, dotted-import preservation, indented
imports, from-imports (simple + dotted + multi-symbol + block),
the `import X as Y` rejection added in PR #2436 (with comment-
stripping + indented + comma-not-alias edge cases), allowlist
anchoring (`a2a` ≠ `a2a_tools`), and end-to-end reproduction
of the PR #2433 failing pattern + the #2436 fix pattern.
3) Wire scripts/test_*.py into CI by adding a second discover pass
to test-ops-scripts.yml. Top-level scripts/ tests live alongside
their target file (parallels the scripts/ops/ test layout); the
existing scripts/ops/ pass keeps running because scripts/ops/
has no __init__.py so a single discover from scripts/ root
doesn't recurse. Two passes is simpler than retrofitting
namespace packages. Path filter widened from `scripts/ops/**`
to `scripts/**` so PRs touching the build script trigger the
new tests.
