Use PYTHONDONTWRITEBYTECODE=1. README.md is the complete acceptance contract, existing tests are smoke tests. Implement and verify every requirement, add regression tests, then report concrete checks and changed files. Path constraints are instructions, not filesystem isolation. Finish the prepared project against README.md. Complete all review, implementation, testing and integration yourself without delegation. You may use any local standard-library probes and all information in the workspace."

Task complete.\n\n## Summary\n\nCompleted the schedule-planner project against the README acceptance contract in `/private/tmp/odsc-workshop6-v2/schedule-single-t1`.\n\n### Changed files (only the 4 permitted)\n\n| File | What was implemented |\n|---|---|\n| `times.py` | `parse_time(text)` — anchored regex `^([0-9]{2}):([0-9]{2})\\Z` enforcing exactly ASCII `HH:MM`; range check `00:00`–`24:00` inclusive; returns minutes from midnight (`'24:00'`→1440). Raises `ValueError` for malformed/out-of-range/non-str. |\n| `windows.py` | `merge_windows(windows)` — validates each pair (`int` bounds, `0 <= start <= end <= 1440`), drops zero-length intervals, does not mutate inputs, returns sorted disjoint tuples fusing **both overlaps and touching** intervals. |\n| `planner.py` | `free_minutes(lines)` — parses each line as exactly `START-END` via `parse_time`, merges via `merge_windows`, returns `{'busy': merged_list, 'free': 1440 - sum(end-start)}` over merged windows. Empty input → `free: 1440, busy: []`. |\n| `test_planner.py` | Replaced stub with 30 regression tests: valid/boundary/`24:01` times, non-ASCII digits, non-str rejection, unsorted/overlap/touching/contained/zero-length merge cases, non-mutation + identity checks, generator inputs, invalid pairs (negatives, >1440, backwards, floats, wrong arity), plus `free_minutes` error paths (extra separator, missing separator, backwards interval, invalid line type) and a realistic mixed day. |\n\n### Concrete verification results\n\n- `PYTHONDONTWRITEBYTECODE=1 python -m unittest -v` → **30 tests, 30 OK** (`Ran 30 tests … OK`).\n- Additional standalone contract probes run via a temporary script (now deleted) → **ALL CONTRACT PROBES PASSED**, covering: `'00:00'`→0, `'24:00'`→1440; `24:01/25:00/9:00/09:0/0900/24:00:00` all raise; touch/overlap chain `09:00-10:00, 10:00-12:00, 11:30-13:00` → single `(540, 780)` window with `free=1200`; non-mutation of a list input (`assertIs`); generator/iterator inputs; and `ValueError` for all seven invalid-input cases.\n- During review I caught and fixed a real regex pitfall: `$` matches before a trailing `\\n`, so `'09:00\\n'` was wrongly accepted — anchored with `\\Z` instead (regression test added).\n- No bytecode files (`find … __pycache__|*.pyc` → none); temp probe deleted; workspace tree contains only `README.md`, `planner.py`, `test_planner.py`, `times.py`, `windows.py`, `.git`.\n- No commits made (repo currently has no commits at all); no installs; nothing outside the workspace touched.\n\nReady for handoff to grading."
