Scaffold the course repo and author the full curriculum in dependency-chain order, following the settled build decisions in handoff.md. - Scaffold: course README, vendor-neutral AGENTS.md (dogfoods Module 5), _TEMPLATE.md (the fixed 9-section module shape), root .gitignore, ship config. - Modules 1-2: reference exemplars (locked for tone/depth/lab style). - Modules 3-27: full lessons + runnable labs, each following the template, respecting the chain, vendor/model-agnostic, with "feel the pain" labs. - Module 8 hosting comparison web-researched and date-stamped (as of 2026-06-22), not written from memory; expansion-zone modules carry Verify-before-publish. - Capstone: the full loop end to end on the running tasks-app example. Lab code syntax-checked (Python/shell/YAML); every module has the 7 core template sections.

"""Reference test suite for the Module 13 lab. Peek only after you've tried it yourself.
|
|
|
|
Named `reference_test_tasks.py` (not `test_*.py`) on purpose, so `python -m unittest discover`
|
|
does NOT pick it up automatically. To run it directly from the tasks-app folder:
|
|
|
|
python -m unittest path/to/reference_test_tasks.py
|
|
|
|
It assumes `tasks.py` is importable (run it from the tasks-app directory, or copy it there).
|
|
|
|
The point of this file is to show the difference between a test that asserts CURRENT BEHAVIOR
|
|
(a tautology that passes against the bug) and a test that encodes INTENT (and fails until the
|
|
bug is fixed).
