TASK t1_fizzbuzz
Create a file `fizzbuzz.py` in the scratch dir containing a function `fb(n)` that returns a list of strings for 1..n: 'Fizz' for multiples of 3, 'Buzz' for multiples of 5, 'FizzBuzz' for both, else the number as a string. Then run it to verify it works. When the file exists and runs without error, call done.

TASK t2_fix_bug
A file `buggy.py` already exists in the scratch dir. It has a function `has_dup(xs)` that should return True if the list has any duplicates, but it has a bug. Read it, fix the bug in place, and run it to confirm the included tests pass. Then call done.

TASK t3_pipeline
Build a two-step pipeline. First create `gen.py` that writes the numbers 1 through 20, one per line, to a file called `nums.txt`. Run it. Then create `sum.py` that reads `nums.txt` and prints the sum of the numbers. Run it and confirm it prints 210. Then call done.

TASK t4_debug_loop
Create `stats.py` with a function `mean_std(xs)` returning a tuple of the arithmetic mean and the population standard deviation of a list of numbers. It must print mean_std([2,4,4,4,5,5,7,9]) which should be (5.0, 2.0). Run it and confirm the output is exactly (5.0, 2.0). If not, fix and re-run until correct, then call done.

TASK t5_parse
Create `parse.py` with a function `parse_kv(text)` that parses lines of the form 'key=value' (one per line, ignore blank lines) into a dict, with values converted to int when they are all digits. Include a test in the file: parse_kv('a=1\nb=hello\n\nc=42') must equal {'a':1,'b':'hello','c':42}. Run it, assert the test passes, then call done.
