git diff errored to stderr on a malformed revision while wc -l counted empty
stdout, producing three confident IDENTICAL results that meant nothing. Had the
promoted trees actually differed, I would have reported the promotion clean.
The correct check is not 'how many files differ' but 'is the tree object the
same object' -- all three share hash 2acd9374.
All five defects are now visibly one shape: reading a PROXY instead of the
thing. One file instead of the operation, a variable name instead of the shape,
a scope instead of the whole, a pipe's exit instead of the program's, a line
count instead of object identity.
cycles/ one file per Ishikawa -> scientific method -> Six Sigma loop, named
for the DEFECT not the fix, carrying the commit record as written at
the time
findings/ what the cycles produced, cross-cut: live bugs, architecture answers,
and defects in my own measurement
The organising finding is that predictions which came back FALSE produced every
significant result. Eleven of sixty-one failed, and those eleven found: that the
arity table was not drifted but 40% incomplete; that the AST traversal is
irreducible and only rules and judgments move; that guards could refuse through
the seam after all; and that routing el_bin_lookup through the gate did NOT fix
the SIGSEGV, because the fallback strlen was the hazard -- a wrong fix I would
otherwise have shipped as verified.
One cycle was run without committing predictions first and had to be discarded
as rigged. It is kept, in full, as 18-async-half-expressible.md.
