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. Before reading inventory.py or tests or proposing any defect hypothesis, delegate exactly once to adversary. The delegation prompt must contain only the workspace path and \"Read README.md and independently test inventory.py against it. Return concrete input/expected/observed evidence. Do not edit files.\" Wait for returned evidence. Then inspect the code, repair it, add tests and verify. Do not supply suspected bugs or test examples to the child."

Here is the report.\n\n## Process\n1. **Delegated exactly once to adversary** (before reading any code, per instructions) with the exact prompt: the workspace path plus \"Read README.md and independently test inventory.py against it. Return concrete input/expected/observed evidence. Do not edit files.\"\n2. Waited for and received its evidence: **10 concrete failures** with input/expected/observed per case.\n3. Inspected the code and repaired it against those findings.\n4. Added 20 regression tests and verified.\n\n## Defects found & fixed in `inventory.py`\n| # | Contract clause | Original defect |\n|---|---|---|\n| 1 | Constructor copies input | Stored `stock` dict by reference |\n| 2 | Atomic reserve (all-or-nothing) | Deducted incrementally before discovering later failure |\n| 3 | Unknown SKU → `False`, no mutation | Deducted earlier SKUs before hitting unknown one |\n| 4 | Nonpositive qty → `False` | Accepted 0/negative quantities |\n| 5 | Repeated SKU quantities add | `dict(lines)` kept last line, overwriting earlier same-SKU pairs (cancel under-restored) |\n| 6 | Different payload for active ID → `False` | Treated any active ID as idempotent replay → `True` and deducted |\n| 7 | cancel exactly once | Kept record after cancel → double cancel returned `True` and over-restored stock |\n| 8 | Cancelled ID may be reused | Reused ID still had stale active-record behavior |\n| 9 | snapshot detached | Returned the internal dict (mutating it corrupted state) |\n| 10 | Exact replay idempotent (aggregate, order irrelevant) | Replay compared raw line order; also failed requests not remembered correctly |\n\nThe fixed implementation aggregates lines into a quantity map first (validating positivity, rejecting nonpositive, summing repeated SKUs), checks availability against the aggregate before any mutation, stores the aggregate as the record (enabling order-independent idempotent replay and repeated-SKU cancel restoration), and pops records on cancel (exactly-once, ID reuse).\n\n## Verification (concrete)\n- `PYTHONDONTWRITEBYTECODE=1 python -m unittest test_inventory -v` → **Ran 20 tests, OK** (exit 0).\n- Independently re-ran each of the adversary's 11 probe scenarios against the repaired code → all **PASS**, including cancelling a failed request → `False`.\n- No `__pycache__`/`*.pyc` artifacts (count = 0); no stray files; no commits; no memory files written.\n- `git status` shows only the three workspace files (all untracked, as the repo has no initial commit); only `inventory.py` and `test_inventory.py` were modified per the contract.\n\n## Changed files\n- **`inventory.py`** — rewritten to satisfy every README.md clause.\n- **`test_inventory.py`** — expanded from the single smoke test to 20 regression tests covering: constructor copy, atomicity, insufficient/unknown/nonpositive qty, repeated-SKU add, idempotent replay (order & aggregate equality), different-payload rejection, failed-not-remembered, cancel restore/absent/twice/failed/reuse, and snapshot detachment."
