Refs #2983
Three lessons, all from a fan-out's adversarial phase arriving days late and the state it
found the worktree in.
Re-measuring the number is not testing the claim
I hand-verified three STALE verdicts because the skeptic phase had not run. One was
wrong. The skeptic refuted it on four grounds — and I had written all four into that
skeptic's own prompt and then not applied them.
The issue claimed 125 damaged lines in 65 files. I measured 0, proved the pattern
could match by planting a damaged file, and confirmed from history that 63 files once
carried it. Every step sound; the verdict still wrong:
a snapshot hash, and the companion script prints "REFUSING: the corpus moved since the
snapshot was frozen".
lines it does not reach were settled by the owner language decision the issue predicted
— so reporting
0presented a confirmed forecast as a wrong number.Only a claim about the tree as it is can be stale. A verification you write for
yourself tests the half you already believe.
A replacement number can be a moving target
Two readers measured one branch divergence twenty minutes apart:
behind_by1833 and1841, whole-tree difference 5309 and 5315. Both right when taken; either
published undated is the next stale number on the page. Sort replacements into structural
facts (1 commit ahead, 10 files in the three-dot compare, the head's parent is the
merge-base) and readings — and date the second group in the same sentence.
The tree I was measuring had lost 296 files
git statusreported 296 tracked files deleted, and 293 of them exist onorigin/master— the worktree was truncated, not the repository. 19 of 49 files weregone from
.github/workflows/, which two commands shipped this week read off disk tobuild their population.
Found only because git itself stopped working: all three worktrees under
/private/tmphad lost their
.gitpointer while the checkout outside it had not.git -C <main> worktree repairfixed all three in one call;git checkout -f origin/masterrestored the files. The cause is not established — a tmp reaper fitsboth symptoms and was not tested.
What saved the published numbers was luck, not design:
tri issues stalehad printedworkflow files 49, matchingorigin/master, which is what proves that reading was takenon an intact tree. Print the size of what you walked, every time. And the skeptic that
found no
.gitmeasured against the GitHub API instead — making its answer strongerthan the scout's.
Corrected numbers
The backlog sample is now complete at 24 of 24: STALE 8 claimed, 6 judged,
5 confirmed, 1 refuted; HOLDS 3, UNMEASURABLE 13. The 21 / 7 / 3 / 11 I
published was a partial reading of 7 of 8 agents and is corrected here.
Skill 431–433.
