questions/abort.md starts with ## DONE — what is the marker's lifecycle?

[dab00gieman]

The question files in python-study-Neo_1/python-quest/questions/ follow the pattern:

### DONE

# Abort

Source: abort

Files to submit
- abort.py

Allowed functions
- --allow-builtin

abort.md is marked DONE and abort.py exists with a solution. Is DONE flipped when the answer file is written, or after review? And do the empty answers (any.py, compact.py, advancedsort_word_arr.py are bare # Write your solution here stubs) correspond to question files still without DONE?

Measured the actual state on Neo_1 to answer this precisely: DONE is a self-study marker flipped when the answer file is written — and it's currently applied inconsistently.

The numbers from the tree today:

• 112 files in questions/ (one is README, so 111 prompts), 111 files in answers/
• 11 prompts marked ### DONE: abort, append_range, atoibase, basicjoin, boolean_main, btree_min, btree_search_item, btree_transplant, btreemax, capitalize, collatz
• 15 non-stub answers: those 11 plus atoi, basicatoi, btreedeletenode, comcheck

So the two invariants that hold: no DONE prompt has a stub answer (DONE ⊂ solved), and every stub you named — any.py, compact.py, advancedsort_word_arr.py — correctly has no DONE marker. What doesn't hold: four solved prompts are unmarked (atoi, basicatoi, btreedeletenode, comcheck).

Since this is a self-paced repo with no review step, "DONE after review" can't be the rule — there's nobody to review. The workable definition: DONE = the answer file exists and runs against the prompt's test program, flipped in the same commit as the answer. Then today's four misses are just drift from flipping it inconsistently.

Two consistency fixes worth doing: (1) mark the four solved-but-unmarked prompts; (2) resolve the comcheck / comcheck_main split — answers/comcheck.py exists with no question file, and questions/comcheck_main.md exists with no answer file, which makes the pair impossible to mark either way. Rename one to match and both invariants become checkable by a one-liner (grep -L '### DONE' questions/*.md against the stub list).
