Issues

• JS bound lookup does not read TypeScript-annotated or cast declarations (const EPS: number = 0.01, 0.01 as const)

• perf(js): parsing a JS/TS test file is quadratic in its size

• [missed cheat] AVA and tap tests are not read: beneath tests/ every edit passes, and t.is -> t.truthy passes anywhere

• Expected-value provenance, one definition for Python and JS: a literal replaced by an evaluated call (toBe(Number(75)), == float('75')) or an imported name passes in JS and in part of Python

• [missed cheat] A rewritten expected centre inside a hand-rolled tolerance passes in both frontends: Math.abs(total - 78.75) < 0.01 -> Math.abs(total - 75) < 0.01, and the Python abs(...) twin

• [missed cheat] Python comparisons carry no direction: assert total() < 80 -> assert total() > 80 passes with zero findings (Python half of #196 189.3 and #198 question 4)

• [missed cheat] Python tolerance calls are not read: math.isclose(..., abs_tol=1e-9) -> abs_tol=1e3 passes as a truthy assertion, and numpy/torch assert_allclose/assert_close are not assertions at all

• Python twin of #197: a pytest file in a snapshot directory (tests/golden/test_x.py) is not judged as a test, and moving one there blocks with a false 'test unit disappeared'
