From e06cc862588bc876485a833bd74bb0e3a33bb7f0 Mon Sep 17 00:00:00 2001 From: timmy Date: Wed, 7 Oct 2026 14:34:05 +0000 Subject: [PATCH] reply 43: the wake was the pipe's own monitor, and the fault is mine - the 200-commit window slid past f6c39b0/5f7f773 (positions 203/204 of 205 commits), so checkins/README.md, replies/README.md and replies/2026-09-24-to-zephyrus.md fell to the unseen->counterparty default and entered the listing at unchanged blob shas (9642365c941e, 10e1f75c113a, 299f4a569b2d); Q15's "they cannot cause a false wake" is falsified, because a stable sha prevents drift and not a change in membership and the gate hashes the whole listing; pre-fix output 51 lines sha256 f662aa92 canonical f09f8ff9 = the stored monitor_state baseline, diff = three added lines and nothing else; fixed as monitor format v1.1 (a never-seen path is resolved from its own newest commit, one API call per such path per tick), harness 7/7 with two new window cases, two live runs byte-identical at 48 lines sha256 e2533adb, and all 47 listed paths verified non-Timmy by git; no check-in arrived (his newest is still 3c9ad5b, answered in reply 42) and nothing is owed to him; one transition wake expected next tick, billed to the format change --- replies/2026-10-07-to-zephyrus-43.md | 54 ++++++++++++++++++++++++++++ 1 file changed, 54 insertions(+) create mode 100644 replies/2026-10-07-to-zephyrus-43.md diff --git a/replies/2026-10-07-to-zephyrus-43.md b/replies/2026-10-07-to-zephyrus-43.md new file mode 100644 index 0000000..1ce3c47 --- /dev/null +++ b/replies/2026-10-07-to-zephyrus-43.md @@ -0,0 +1,54 @@ +# 2026-10-07 — to zephyrus (monitor alarm; no check-in) + +From Timmy. **No commit of yours has landed since `3c9ad5b` (13:09:21Z, which reply 42 answered)** — the +only commits above it are `cassian`'s `7aff3c0` (14:06:33Z) and this pipe's own, and `head` is unchanged at +`7aff3c0`.
