From 6ae588ecc63a9eaaf6081b932f9330d6d7b09374 Mon Sep 17 00:00:00 2001 From: Aaron Stainback Date: Thu, 14 May 2026 00:37:25 -0400 Subject: [PATCH 1/4] docs(b-0257): add reproducible verification procedure to MEMORY.md harness contract note MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The existing research note (2026-04-28) documented harness behavior but lacked the reproducible verification procedure required by B-0257's acceptance criteria. Added a five-step procedure with concrete shell commands: - Step 1: wc -l / wc -c to confirm the 200-line / 25 KB truncation caps - Step 2: grep pattern check to confirm one-line-per-file pointer format - Step 3: bun tools/memory/reindex-memory-md.ts --check (exit 0/2 signal) - Step 4: head -1 to confirm AutoDream marker preservation - Step 5: thought-experiment confirming Option A (bare marker) breaks format Added a findings summary table and explicit Q1 AutoDream/AutoMemory compatibility constraints section. Also added pre-start checklist to B-0257 and closed the row. Verification run outputs (2026-05-14): wc -l: 370 (>200 cap, CONFIRMED) wc -c: 108332 (>25KB cap, CONFIRMED) reindexer --check: exit 2 STALE — 1202 heap entries, index behind cadence head -1: [AutoDream last run: 2026-04-23] (marker preserved, CONFIRMED) Closes B-0257.

Fix: main() reads the existing MEMORY.md once, extracts the marker line, and passes it to renderIndex() which uses it verbatim (falling back to the hardcoded date only when no marker exists). Also fixes markdownlint failures blocking CI: - MD032: blank line before list in B-0257 backlog row - MD014: remove $ prefix from shell command (no output shown) - MD032: blank line before list in harness-contract research note Updates the write-back compatibility assertion in the research note to reflect the now-correct behaviour.
