Development record

2026-10-31 — spc-2609202134338445 step 11, fix round 2: no ignore rule is added for .abcd/work/.decisions.lock. Grounds: no code at this tree creates it; it was the lock of the single decision log, and its ignore line went with the log in v0.15.0, while abcd decide now flocks the decisions folder and leaves no file. A copy left by an older release is a static untracked file, the same in the start's checkout digest and every later one, so it hands nothing back; only an older release writing it during the reviews would, and every record writer's write changes the checkout anyway. An ignore rule for a file no current code writes would be configuration for nothing.
