Checks 4–6: the structural requirements read in an output — parah adumah, carrier centered, chelbenah

structure_not_content.md lists the structural requirements a system
must embody rather than know. Three of them show in the text of a
model's output the way an authority claim does, and are now read the
same way — by sentence, by pattern, over the raw output:

  parah_adumah      the output claims to have verified, validated or
                    corrected itself, or that no outside check is
                    needed ("the claim of self-correction is a
                    structural violation"; the Barth limit). "Verified
                    by the auditor" is not it; "verified by me" is.
  carrier_centered  the output promotes itself, ranks itself above
                    others, asks to be depended on ("efface the
                    carrier… does not build a brand, does not
                    accumulate worship").
  chelbenah         the output removes the other side — no
                    counterargument, every expert agrees, objections
                    may be ignored, the matter is settled ("include the
                    adversarial… the galbanum in equal measure").

Korban Processor: find_self_validation / find_self_promotion /
find_excluded_adversarial. Talmudic Engine: halt/structure.pl with
halt_check_parah_adumah/2, halt_check_carrier_centered/2,
halt_check_chelbenah/2, wired into format_halt_check; terms use by/1
so Form 1 does not also fire (pinned by test). Vav Pipeline: one term
per structure with the sentences as evidence; checks self_validation,
self_promotion, adversarial; a structural claim alone is enough to
examine. L3: bedikot.structure. These are verdicts on the output; the
system does not halt on them.

Specs: Tamid §1.1 (six checks), Vayakhel §3.9, Architecture §3.5,
KOHEN.md. Doorpost 6c8933e7… → c4353837…. Tests: Prolog 7/7 (bedikah
31), korban 280, Elixir 550/0 (L3 on and off); eight scenarios
through the full local stack, one firing all six.
