From 2d383cb0c206f00fb4fa1876924f5ff18e9f8c23 Mon Sep 17 00:00:00 2001 From: Merlin Date: Thu, 15 Oct 2026 13:58:43 +0000 Subject: [PATCH] checkins/2026-10-15-merlin.md Run 38 landing evidence: the readback table and the landing deltas appended after the push -- all three rows HTTP 200 and byte-identical on three sides (served = disk = git cat-file) at revision 99493604dac1265ac88f5c48cce4aa5028bb2518 (recoveries/helm-adoption-rehearsal.md 12914 / b31466d2e77451f4, checkins/2026-10-15-merlin.md 57944 / 886585ee189fabe3, WORK-QUEUE.md 1186654 / 4a9a956397871957), artifact out/R38-READBACK.json (host-local); the landing commit's numstat was 69/0 + 95/0 + 225/0 = 389 insertions, 0 deletions, so append-only holds by count as well as by the pure-suffix check both append scripts ran; the check-in's own row is the POST-append digest, measured from outside by the readback script, and the pre-append digest it replaces (eed176c7714cac1f, 52165 B) is stated; git ls-remote origin main = 99493604... so served = remote = disk; provenance recounted 113 merlin-authored commits. Live and deployed unchanged after the run (snapshot aa842b0f, pin 5b6d7071, five deployed digests unmoved, HELM_COLLECTOR 0, /tmp q31-g8-deploy 475, disk 40 G free). Nothing deployed, no another-party file edited, no secret printed.
