sugya, step 1: the facts behind each threshold, verified at startup like the anchors

specs/sugya.md §IV–V step 1. talmudic_engine/src/halt/sugya.pl (a
Doorpost file beside anchors.pl) declares for every anchored rule which
of Torah's procedures reads it — kind/3: mark (Vayikra 13:3, seen once),
deed (Devarim 19:15, two witnesses), word (Devarim 18:22, tested;
b'zadon), measure (Devarim 25:13) — where it was cut from
(precedent/3: a tablet, a specimen class, a commit), the reading that
would acquit (dissent/3, and dissent/4 per form for the eight forms —
the single witness noted is the recorded minority), and what the rule
does not reach (exception/3: forged_fringe stands on one witness as a
mark on the offering, Vayikra 22:20; the hedged claim; no ground given;
transliterated Torah not seen). sugya_of/2 gathers one rule's record.

VavPipeline.Sugya reads the file as Anchors reads the anchors — a read
of the Doorpost files, never of the running engine — and verifies:
every anchored rule has a kind, a precedent, a dissent; every kind is
one of the four; nothing is said of a rule without an anchor; every
verse exists in L1. Doorpost.verify_identity chains it after
Anchors.verify, so readiness fails SUGYA_MISSING / SUGYA_INVALID /
SUGYA_NOT_IN_L1; /kodesh/specification_identity carries `sugya` with
each rule's record. Nothing on the verdict changes yet (step 3).

Every verse cited — 17 — read from L1 before this commit. Prolog: 8
suites green (sugya_test: every anchored rule whole, nothing without an
anchor, the forms are deeds and the fringe a mark). Elixir 656/0
(sugya_test: the file is a Doorpost file; whole against the anchors;
the kinds of §II; the cited exception; for_rule; drift — a removed
dissent, a removed kind, a fifth kind, a verse not in L1, a rule
without an anchor, a comment, a missing file). Doorpost pin → cb2f3135…
(31 files).

+%%
+%% anchors.pl gives every rule the verse it STANDS on. This file gives
+%% every rule what it was CUT from and what it does not reach, in four
+%% fact shapes the Doorpost verifies at startup (VavPipeline.Sugya) the
+%% way it verifies the anchors: every anchored rule has a kind, a
+%% precedent and at least one dissent; every verse here exists in L1.
+%% A rule without a sugya is a rule the system has added (Devarim 4:2).
+%%
+%% Torah establishes a matter three ways, by what kind of thing it is
+%% (sugya.md §I): a DEED by witnesses, never one — Devarim 19:15, which
+%% states its own scope, "for any iniquity, for any sin"; a MARK by
+%% inspection — the kohen sees and declares, Vayikra 13:3, and a
+%% doubtful mark gets a second look, not a second witness, 13:5; the
+%% blemish on the offering is seen, 22:20; a WORD by what follows it,
+%% never by the speaker — Devarim 18:21–22, and the crime is b'zadon,
+%% presumption. The paired reading is a MEASURE — Devarim 25:13.
+%%
+%% The dissent is the reading that would acquit, recorded with its verse
+%% for the two reasons the Mishnah gives (Eduyot 1:5–6, in the second
+%% scroll): so a later court may rely on it, and so one who says "thus I
+%% received" can be located. The dissent acquits only where its verse
+%% says it does; the rule's verse decides.
+%%
+%% Nothing here learns. A new dissent is a commit that moves the pin.
