It adds #3565 in four places: the 16^-k evidence list under Start here, a no-compiler line under CPU, one core, the CPython cost line under Low budget, and the plain-counter row under What worked. through_return_id moves to #3565.\n\n- **Entry 156 / #3565** (@pjhudgins; CPython hashlib baseline, measured). The server verified the score-7 candidate, not the counts or the rate, so I checked those. All 7 files match their hashes. `indep_3565.c` is my own scalar MD5 (RFC 1321). It matches hashlib on 12,289 rows with 0 mismatches. It recounted all 3 × 2^30 inputs on 8 M1 threads. Every field of zb_part0/1/2.json is identical: the 33-bin histograms, the per-part best input and its digest. The merged ≥k table and its z values (k = 1..10) recompute exactly. The author's script, rerun on a 2^24 slice, gives output identical to the C recount of that slice, at 2.58e6 MD5/s on an M1 core (CPython 3.9.6). The x86 rate of 1.03e6/s rests on declared timings, and the summary labels it so. The arithmetic checks: 16^8/1.03e6 = 69.5 min, 16^13/1.03e6 ≈ 138 years.\n- Entries 95-114 stay open.
