PY-1:
from collections import Counter
import re, unittest

def top_k_words(text, k):
words = re.findall(r"[a-z0-9']+", text.lower())
counts = Counter(words)
ranked = sorted(counts.items(), key=lambda kv: (-kv[1], kv[0]))
return [w for w, _ in ranked[:k]]

class TestTopK(unittest.TestCase):
def test_counts(self): self.assertEqual(top_k_words('b a a b c', 1), ['a'])
def test_ties(self): self.assertEqual(top_k_words('b a', 2), ['a', 'b'])

GIT-1 (disposable repo):
git branch fix/login # keep the commit on a new branch
git checkout main
git reset --hard origin/main # restore main; safe only on disposable clone
git checkout fix/login
git reflog # locate lost tip: git branch rescued

DBG-1: KeyError 'total' → probably missing key initialization; first command: python -m unittest -v or add a print/pdb breakpoint. Off-by-one 7 vs 6 → likely inclusive boundary in range/slice; first command: inspect the window bounds with a printed index trace.

M-1: df/da = b + 1 = 4.0; df/db = a = 2.0. Verify: (f(2.00001,3) − f(1.99999,3))/(2e-5) ≈ 4.0 ± 1e-6.
M-2: 1040 + 256 + 6144 = 7440 — matches run_artifact.json parameter_ledger.total_parameters.
M-3: Position t reading t+1 would leak future tokens, making the next-token loss trivially solvable and breaking autoregressive generation; the upper-triangular mask sets logits to -inf for all j > t before softmax, zeroing their attention weight.
M-4: 32768 trainable vs 1,048,576 dense (~3.1%); the adapter output is scaled by alpha/r = 32/16 = 2.0 before being added to the frozen base weight's output.
M-5: exp(4.0372) ≈ 56.7 — high but sane for a 10-step CPU smoke run on tinyshakespeare; it verifies plumbing, not convergence. Falsifiers: train loss rising, NaN/Inf gradients, checkpoint reload mismatch.
