 # How to work in this repo
 
+## READ FIRST — rules I have broken in front of Captain Bob (2026-11-11)
+
+1. **NEVER run an acceptance test in the background. EVER.** (Bob: "You are NOT to run acceptance tests in
+   background EVER!") No `run_in_background`, no `&`, no detached loop, no "it might outlast the tool timeout".
+   One stage per foreground command, read its result, then the next. I broke this twice on 2026-11-11.
+2. **Before doing anything, check it against CLAUDE.md, not just before the session.** Having read a rule is
+   not following it. I had summarised the foreground rule to Bob and broke it anyway.
+3. Every log and every CSV is evidence and is committed — passing, failing, stopped.
+4. Never create a branch, never stash, never fix unasked, never push without Bob saying push.

 Source of authority: `.claude/CLAUDE.md` (wins), then the FABRIC record (`docs/fabric/`, FABRIC-3 living),
 then `docs/v4.0.0/`, `docs/reference/ROADMAP.md`, `boards/BRINGUP.md`. Code wins over all documents.
