bigmerge c6ba0677f0 log v1 experiments: nineteen cycles, organised by the method that produced them
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: prohibition becomes a query over emitted relations

I said prohibition could not move because "a #error has no runtime". That
conflated two separable things: WHEN a violation is detected (build time --
correct, and unchanged) and WHERE the rule and the checker live (the compiler
-- assumed).

A prohibition is a containment relation over the call graph. So codegen now
records what it saw:

    sneaky   calls raw_sql
    allowed  calls raw_sql
    allowed  calls @repository
    repository calls prohibits:raw_sql

and tools/check/prohibitions.sh decides, at build time, outside the compiler.

PREDICTIONS AND RESULTS
  P1 codegen can emit the call graph it already walks   TRUE
  P2 the check becomes a query outside the compiler     TRUE
  P3 all prohibition decisions leave codegen            TRUE  zero #errors now
  P4 violations still caught at build time              TRUE  exit=1
  P5 codegen drops below the 4661 baseline              FALSE 4962, +301

P5 is the finding. The TRAVERSAL is irreducible -- you must walk the AST to
find calls, and those ~120 lines do not move no matter who decides. What is not
irreducible is the rule (which names) or the decision (#error). Those left. I
predicted the whole 223 lines would go because I had not separated walking from
adjudicating.

Still compiled, and measured rather than assumed: the capability-tier system
(cap_check_call, is_self_formation_call, is_dharma_call, is_llm_call,
cap_record_violation, emit_cap_violations) is 76 lines of the same shape --
prohibits_WITHIN rather than prohibits_outside, so the checker needs the
opposite polarity to absorb it.

98/98 native, 4/4 prohibition_query.sh, 7/7 seam_binding.sh, fixpoint ok.
