    Test the pipeline

    The telemetry pipeline is now split into parse_row() and check_limits(). Write assert tests for both, good rows, rejected rows and readings right at a limit, so that each of three planted bugs makes…

    Seeded simulation

    Simulate 100 sensor readings, each with a 5% chance of a glitch, and seed random with 42 so the count is the same on every run and a test can check it exactly, then pick a kind for each glitch with…

    Test the error

    Edge cases

    Write assert checks for mean(): an ordinary list and a list with one value first, then the edge cases, an empty list that should give None and lists with negative values, so broken copies of the…
