When to stop, stage B1

Written by tools/saturation.py report at 2026-10-11T14:41:42Z. The rule: saturation.py docstring; J, 2026-09-29.

The thresholds (10 average rooms before a round, rounds of at most 25, three empty rounds to a marker, the check-in at 60% of the words) are this design's discovery heuristic, J's recorded choice (2026-09-29). The literature gives the rule its form, a run with nothing new after a base; it does not fix these numbers.

Where the reading stands

rooms read 705 of 705
share of the words read 100.0%
rooms left 0
words left, in average rooms (2604.4 words each) 0.0

The markers

marker rooms read average rooms read coverage unseen kinds share of words
1: three empty rounds (the first stop) 499 507.0 0.9974 18.58 71.9%
2: three more empty rounds 574 581.5 0.9979 20.01 82.5%
3: the draw read 660 656.4 0.9983 18.02 93.1%
check-in: 60% of the words read before marker 3 408 423.8 0.9962 21.07 60.1%

Marker 1's empty run, from the last new kind (room 421, 434.9 average rooms) to marker 1: 72.1 average rooms and 78 rooms. It is the second pass's target, never fewer than 30 rooms.

The draw

86 rooms drawn at random from the 131 unread at marker 2, 195182 words (the three rounds between the markers read 193932); 0 brought a new kind. With 95% confidence, 3 or more unread rooms carrying an unseen kind are ruled out.

What is left (0.0 average rooms) is no larger than the draw was (74.5): reading everything costs no more than the draw did.
