2. Input SHA-256 equals README value — PASS.
3. n_input_rows = 2498 = wc -l minus header — PASS.
4. Table1 n_days sum = 2498 = n_input_rows — PASS.
5. Baseline cross-check: mean change −0.042851 bp equals 100·(last−first)/(n−1) telescoping identity — PASS.
6. Exclusion ledger: 2498 − 1 − 2497 = 0 rows in estimand windows; n_analysed = null consistent — PASS.
7. n_treated = 0 consistent with all dates < 2020-03-04 and post_cut never 1 — PASS.
