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.

EXPERIMENT: temporal adjudication moves out; the placeholder stays
The previous pass moved the type DATA and left the judgment inline, which I
stated rather than hid. This finishes it.
PREDICTIONS AND RESULTS
P1 codegen can emit operand-type relations TRUE
"main calls temporal:instant_plus_instant"
P2 the affine rules are a small closed set as data TRUE 6 rules
P3 violations still caught at build time TRUE exit=1
P4 the reporter leaves codegen TRUE 4538 -> 4507
P5 the TIME_TYPE_ERROR placeholder must STAY TRUE
P5 is the boundary of this whole approach. The emitter has to emit SOMETHING
for an illegal expression -- it cannot emit nothing and it cannot decide what
the program meant. So the placeholder is irreducible in the same way the AST
traversal was: what moved is the judgment and the wording, not the fact that
something must be written.
The rules are affine algebra and the set is closed because there are only two
kinds of thing. An Instant is a POINT, a Duration is a DISPLACEMENT: add a
displacement to a point, subtract two points for a displacement, combine
displacements. Nothing else is meaningful, which is why the enumeration in
temporal.rel cannot grow the way an allowlist does.
A defect in my own checker, found by running it: the .rel file uses aligned
columns and my awk assumed a single space, so the message came out with the
rule key still prefixed. Same class as the multi-line header parse in the arity
pass -- formatting assumptions that only fail when you look at the output.
98/98 native, 6/6 temporal_query.sh, fixpoint ok.
