LH034 checkpoint, 29 October 2026

Working record, unreviewed. Read data/read-2026-10-29T0635Z, started 06:35 UTC: dist/index.json and the summaries for 27 October (day 6, HTTP 200) and 28 October (day 7, HTTP 404, not yet posted; fetched by the next read). Tables: data/tables.json. Written by the scheduled daily run.

New releases in the fixed lines

dist/index.json now lists v24.22.2 (dated 27 October) and v26.13.0 (dated 28 October), neither flagged security. Both sit above the fixed releases in their lines, so measure 1's at-or-newer rule counts them; it does not separate them from the fixed release.

Measure 1, day 6 (Tuesday 27 October)

Line Day 5 Day 6 Line downloads, day 6
22 52.7% 53.3% 8.7 million
24 69.3% 70.9% 14.5 million
26 61.5% 76.4% 3.1 million

Days 0 to 5 are unchanged (each day's value is from the earliest read holding it).

Measure 2, day 6

13.2 per cent of version-attributed downloads came from lines the release does not fix (12.5 on day 5); line 20, 6.5 per cent; line 25, 0.8 per cent. Requests with no version: under 0.01 per cent of total (30.2 million).
