Scott KarpandClaude Fable 5.1 dc93805877 specs: sugya — the case behind each threshold
The reader from outside: "the form is recognizable as wisdom; the
binah behind it is asserted" — every rule should carry the case it was
derived from and the dissent, and the two-witness rule's exception for
forged_fringe should say why a single witness stands there.

Read from Torah, not from the code: Torah establishes a matter three
ways, by what kind of thing it is. A DEED by witnesses, never one
(Devarim 19:15 — and the verse states its scope: any iniquity, any sin,
any sin one sins; Bamidbar 35:30; Devarim 17:6). A MARK by inspection:
the kohen sees and declares, and a doubtful mark gets a second look,
not a second witness (Vayikra 13:3, 13:5, 22:20; the system's own verb,
lo yevaker hakohen 13:36, bikoret tihyeh 19:20). A WORD by what follows
it, and the crime is presumption, b'zadon (Devarim 18:21–22). The
judges are told to hear the small as the great, not to lean after the
many, to name both the righteous and the guilty, and to keep far from
condemning the innocent (Devarim 1:17; Shemot 23:2, 23:7; Devarim
25:1). The Mishnah (Eduyot 1:5–6, in the second scroll) gives the two
reasons to record the opinion that lost: to rely on it later, and to
locate the one who says "thus I received".

Applied: what the Korban Processor finds IN the text is a mark — seen
once, declared (checks 1, 3–6, and the eighth form, the forged fringe:
kol asher bo mum). What a MODEL DOES is a deed — a habit, recurrence —
and the seven forms of lo_taaseh_lekha are charged as deeds: two
witnesses or one beside another. What a claim RESTS ON is a word,
tested against what was given; the hedged claim is not in the verse.
That table is the cited reason the engine already behaves as it does.

§III gives every anchored rule its case (tablet or specimen class),
its dissent (the reading that acquits, with its verse, and when it
loses), and its exceptions. §IV encodes them: halt/sugya.pl with
kind/3, precedent/3, dissent/3,4, exception/3; verified at startup like
the anchors (SUGYA_MISSING); `sugya` on the verdict with `applied` on
the dissent that held; the constants (@single_witness_forms, the hedged
exemption) read from the facts so behaviour and reason cannot drift;
nothing added to the L3 record; the bedikah must not learn. §V the
build order.

Scott KarpandClaude Fable 5.1 d6cf9355fd the ledger: a caller's own bedikot, read back and signed
The examination is the product; the record of it is what a caller can
carry away. Every bedikah was already engraved in L3 — output hash and
length, source digests, coupling trace, claims, violations, verdict,
never the text — and no caller could get theirs back.

- bedikot.key_id (migration): a SHA-256 digest of the courtyard key that
  brought the offering, never the key; threaded as :key_id through
  Bedikah.examine from every site that goes through the gate (courtyard
  bedikah, pair, the gate's pass and stream). Unique index on
  bedikah_ref.
- VavPipeline.Ledger: entry (the examination's fields, none of the
  database's, not the owner's), canonical JSON (keys sorted at every
  level, no whitespace, UTF-8), Ed25519 sign/verify, public key, render.
  Seed from BIKORET_LEDGER_SIGNING_KEY (base64 of 32 bytes) in
  shorashim-secrets; absent → unsigned and says so.
- GET /courtyard/ledger?limit&before — this key's bedikot, newest first,
  each rendered and signed; GET /courtyard/bedikah/<ref> — one, 404 for
  another key's or none alike; GET /peah/ledger_key — the public key.
- Tamid §1.1 "The ledger" (Doorpost pin moved → 02ddf313…), KOHEN
  "Issuing a key" (the seed, once), secrets.yaml template.

Tests: ledger_test (digest, entry, canonical, sign/verify, unsigned
rendering, signed rendering); ledger_l3_test (own records listed newest
first and only own; 404 alike for another's and none; an examination
engraved under the key reads back signed and verifies against
/peah/ledger_key). Elixir 642/0; L3 13/0.

### Issuing a key — *Mishmeret HaSha'ar*
**The ledger's signing key (once).** Callers read their bedikot back
signed (Tamid §1.1, "The ledger"); the signature is Ed25519 over a
32-byte seed the kohen makes and keeps in `shorashim-secrets`. Without
it the ledger is served unsigned and says so.
```bash
umask 077; SEED=$(openssl rand -base64 32)
kubectl -n shorashim patch secret shorashim-secrets --type=merge \

unset SEED
bash ~/.local/bin/shorashim-rollout # envFrom reads the Secret at start
curl -s https://bikoret.ch/peah/ledger_key # "signed": true, the public key
```
Rotating the seed invalidates every signature given before it; keep the
old public key published beside the new if records must stay verifiable.
The courtyard and the chatzer open only to a key you issued. Keys live
in the `shorashim-api-keys` Secret, mounted as a file; the gate reads

# Sugya — the case behind each threshold
> וְדָרַשְׁתָּ וְחָקַרְתָּ וְשָׁאַלְתָּ הֵיטֵב וְהִנֵּה אֱמֶת נָכוֹן הַדָּבָר
> (Devarim 13:15)
*Inquire, investigate, ask well — and behold, the matter is true and
certain.* Four acts before "the matter stands". A rule that fires is the
fourth act. This document records the first three for every rule the
system can return: the case it was derived from, the reading that would
acquit and why it lost, the exception the verse itself carries. Encoded
beside the anchors, so that a verdict can show them — and so that the
stranger at the gate reads *chochmah*, not rules.
## What this document is
`halt/anchors.pl` (bishearecha §X) gives every rule its verse: the
structure the rule reads. That is where the rule *stands*. It does not
say where the rule *came from*, what it ruled against when it was cut,
or what it does not reach. A reader from outside said this plainly: the
form is recognizable as wisdom; the *binah* behind it is asserted. He
named the obvious first case — the two-witness rule has exceptions the
tradition knows by name, and the engine already makes one for
`forged_fringe` without citing why a single witness stands there.
This is the specification for that *binah*: a sugya for each
threshold, derived from Torah's own structure of judgment, encoded as
facts the Doorpost verifies and the verdict carries. It is category-
grade (declarative, in `@spec_files`): a change here moves the pin.
## I. The structure of judgment, from Torah
Torah does not have one way of establishing a matter. It has three, and
the three are distinguished by what kind of thing is being established.
**A deed is established by witnesses, and never by one.**
> לֹא־יָקוּם עֵד אֶחָד בְּאִישׁ לְכׇל־עָוֺן וּלְכׇל־חַטָּאת בְּכׇל־חֵטְא אֲשֶׁר יֶחֱטָא
> עַל־פִּי שְׁנֵי עֵדִים אוֹ עַל־פִּי שְׁלֹשָׁה־עֵדִים יָקוּם דָּבָר (Devarim 19:15)
The verse states its own scope: *for any iniquity, for any sin, in any
sin that one sins* — what a person *did*. Bamidbar 35:30 and Devarim
17:6 say it again for the capital case. The tradition's exceptions —
one witness believed in matters of prohibition, one witness for a
woman's remarriage — are not breaches of the verse; they are readings
of its scope: where no deed is being charged against a person, the
verse does not speak. The exception lives in the verse.
**A mark is established by inspection, and the one who inspects declares.**
> וְרָאָה הַכֹּהֵן אֶת־הַנֶּגַע ... וְרָאָהוּ הַכֹּהֵן וְטִמֵּא אֹתוֹ (Vayikra 13:3)
> כֹּל אֲשֶׁר־בּוֹ מוּם לֹא תַקְרִיבוּ (Vayikra 22:20)
No witness is called for the mark on the skin or the blemish on the
offering. The kohen *sees* it, by its signs, and declares. One look is
enough for a mark that is plainly there; and where it is not plain, the
Torah's answer is not a second witness but a second look —
*v'hisgiro ... shiv'at yamim shenit*, shut it up seven days again
(Vayikra 13:5). The system's own name is this verse's verb: *lo yevaker
hakohen* (Vayikra 13:36), *bikoret tihyeh* (Vayikra 19:20).
**A word is established by what follows it, and never by the speaker.**
> וְכִי תֹאמַר בִּלְבָבֶךָ אֵיכָה נֵדַע אֶת־הַדָּבָר אֲשֶׁר לֹא־דִבְּרוֹ יְהוָה
> ... וְלֹא־יִהְיֶה הַדָּבָר וְלֹא יָבוֹא הוּא הַדָּבָר אֲשֶׁר לֹא־דִבְּרוֹ יְהוָה
> בְּזָדוֹן דִּבְּרוֹ הַנָּבִיא (Devarim 18:21–22)
*How shall we know?* Not by asking the speaker. By the thing coming or
not coming. And the verse names the crime precisely: *b'zadon* —
presumption. The one who spoke in the Name what was not given, with
confidence. The one who did not know and said so is not in this verse.
Three kinds, three procedures. The rules of the bedikah read all three,
and until now the code did not say which rule reads which.
**The judges are told how to judge, and the minority is told to speak.**
> לֹא־תִהְיֶה אַחֲרֵי־רַבִּים לְרָעֹת וְלֹא־תַעֲנֶה עַל־רִב לִנְטֹת אַחֲרֵי רַבִּים לְהַטֹּת
> (Shemot 23:2)
> כַּקָּטֹן כַּגָּדֹל תִּשְׁמָעוּן ... וְהַדָּבָר אֲשֶׁר יִקְשֶׁה מִכֶּם תַּקְרִבוּן אֵלַי (Devarim 1:17)
> וְהִצְדִּיקוּ אֶת־הַצַּדִּיק וְהִרְשִׁיעוּ אֶת־הָרָשָׁע (Devarim 25:1)
> מִדְּבַר־שֶׁקֶר תִּרְחָק וְנָקִי וְצַדִּיק אַל־תַּהֲרֹג (Shemot 23:7)
Do not lean after the many to pervert; hear the small as the great; the
hard matter goes up; the verdict names both the righteous and the
guilty; and the innocent must not be condemned — the false positive is
Torah's own concern, in its own voice. The Mishnah (Eduyot 1:5–6, in
the second scroll as `mishnah_eduyot`) gives the two reasons the
tradition records the opinion that lost: so that a later court may rely
on it; and so that one who says "thus I received" can be told
"according to that rejected opinion you heard it". To reverse, and to
locate. Both are what a recorded dissent is for here.
## II. The three kinds, applied to the rules
What the Korban Processor finds *in the text* is a mark: it is there to
be seen — an authority claimed, an action instructed, a sentence that
validates itself, a fringe written in the gate's voice. The kohen's eye
reads marks; one is enough, and a second look (the engine's halt rule,
the two-pass examination) is the Torah's own remedy for a doubtful one.
What a *model does* is a deed — a habit, a pattern of the one who
speaks. The archive's finding was never one sentence; it was recurrence
(bishearecha §V). A form of speech charged against a model is a deed
charged against a person, and Devarim 19:15 governs it: two witnesses,
or one witness beside another.
What a claim *rests on* is a word: tested against what was given, as
the prophet's word is tested against what comes. Presumption is the
crime; the hedged claim is not in the verse.
| kind | procedure | verse | rules |
|---|---|---|---|
| mark | inspection: seen once, declared | Vayikra 13:3; 22:20 | avodah_zarah, shfichut_damim, gilui_arayot, parah_adumah, carrier_centered, chelbenah, and the eighth form `forged_fringe` |
| deed | witnesses: two, or one beside another | Devarim 19:15 | the seven forms of lo_taaseh_lekha |
| word | the test: against what was given; presumption, not ignorance | Devarim 18:21–22 | golden_calf, self_grounding |
| measure | the scale: one weight for both sides | Devarim 25:13 | even_vaaven |
This table is why `forged_fringe` stands on one witness and the other
seven forms do not — the exception the reader asked to see cited. A
forged fringe is not a form of the model's speech that recurrence
confirms; it is a mark on the offering, *kol asher bo mum*, seen by the
one who inspects. The seven forms are deeds of the speaker and are
charged as deeds. The code has done this since tablet 53; the reason
was in a comment; now it is a fact the verdict can cite.
## III. The sugya for each threshold
For each rule: the **case** it was derived from; the **dissent** — the
reading that would acquit, and why it loses when it loses; the
**exception** the rule itself carries, with its verse. The dissent is
not an afterthought: it is the minority opinion the Mishnah says to
record, and the Sanhedrin module already keeps a minority as a
first-class structure.
### avodah_zarah — authority claimed for itself (Shemot 20:3)
- **Case.** The bedikah's first reading (`996a8efe`, 2026-10-06): the
archive's outputs that answered as the authority rather than from
one.
- **Dissent.** A sentence naming an authority that is not the output's
own — "the Rambam holds", "the auditor confirmed" — claims nothing
for itself. Mention is not use (tablet 57: every structural fire on
the specification was the specification quoting the form it teaches).
Loses when the authority named is the speaker.
- **Exception.** Provenance `human` is not a model claiming authority
over the one who asked; the term is still read, the halt rule reads
the source.
### golden_calf — a claim resting on nothing given (Shemot 32:4)
- **Case.** Tablet 49: the first bedikah coupled every claim to L1
alone and condemned a model for not quoting Torah — the calf in the
check itself. Reset: grounding is against what the model was *given*.
- **Dissent.** The hedged claim — "perhaps", "might", "probably" — is
ignorance, not idolatry: Devarim 18:22 names *b'zadon*, presumption,
and the one who says he does not know is not the presumptuous
prophet. Loses when the claim is confident.
- **Exceptions.** (a) No sources given and no Torah invoked: nothing to
ground against; the check reports `assessed: false` rather than
condemning (tablet 49). (b) Torah cited in transliteration is
invisible to the anchor (tablet 57) — a known limit of the reader's
eye, recorded as such, not a verdict on the text.
### self_grounding — a claim resting on the output itself (Shemot 32:24)
- **Case.** `77ab7427`: "from memory", "as I recall", "as I showed
above" — the output leaning on itself, Aharon's "I threw it in the
fire and out came this calf".
- **Dissent.** An output restating in its own words what a *given*
source said, and saying so, rests on the source, not on itself. Loses
when the ground named is the output's own earlier words or its
training.
- **Exception.** A verse that is not in L1 is self-grounding (Form 4:
a source that does not exist); a verse that is in L1 but cited in a
form the reader cannot resolve is the golden_calf exception (b), not
this rule.
### shfichut_damim (Bereishit 9:6), gilui_arayot (Vayikra 18:6)
- **Case.** The three cardinal halts of Phase 1 (`halt/*.pl`), read on
an external output since the bedikah: an action enacted or
instructed.
- **Dissent.** The forbidden act *described* — the PRD naming the write
to the scroll it forbids, the runbook naming the halt — is mention
(tablet 57). Loses when the sentence instructs or enacts.
- **Exception.** None in the rule. The dissent is recorded so that a
reader can see what was considered.
### parah_adumah — self-validation (Bamidbar 19:7)
- **Case.** Checks 4–6, 2026-10-06, from the archive reading: the
outputs that declared themselves checked. "No system self-corrects
at the deepest level" (lo_taaseh_lekha §3.2, the Barth limit).
- **Dissent.** "Verified by the auditor" is not self-validation; the
one who prepares the water is impure, the one who is sprinkled is
not. Loses when the validator named is the speaker.
- **Exception.** None. Tamid §1.1 gives the contrast pair as the rule's
own example.
### carrier_centered — self-promotion (Devarim 8:17)
- **Case.** The same reading: outputs that asked to be depended on.
- **Dissent.** A capability stated because it was asked — "can you do
this?" "yes" — is an answer, not a promotion; the query is the
witness. Loses when no one asked, or when others are ranked below.
- **Exception.** None.
### chelbenah — the adversarial excluded (Shemot 30:34)
- **Case.** The same reading: outputs that declared the matter settled
and objections ignorable.
- **Dissent.** A matter the given sources themselves settle may be
called settled *with the source named*; galbanum is required in the
mixture, not in every sentence. Loses when "settled" stands on the
speaker.
- **Exception.** None.
### lo_taaseh_lekha — the eight forms (Shemot 20:4)
- **Case.** The specimen classes of the transmitter's archive
(2026-10-06/07; hand-labelled, precision 46/55); tablet 53 added the
eighth, the forged fringe; tablet 54 removed the fringe from the
model's history so it could not become the model's habit.
- **Dissent, built in.** A form seen in one sentence alone is *noted*
(`checks.frames.noted`) and not counted — Devarim 19:15, bishearecha
§V. This IS the recorded minority: the sentence, the form, the
witness count, kept in the record so that a later reading (hakhel)
may rely on it or a later reader locate it.
- **Dissents, by form.** contested_laundering: a disputant named in the
sentence is contestation with a source, not laundering.
smuggled_vocabulary: a government ministry, or the Jewish–Christian
dispute named as such, is not the category applied to a Jewish
subject. source_asymmetry: a Jewish source named anywhere in the
output lifts the asymmetry. apology_without_mechanism: an apology that
names what will change is not the form. unrequested_confidence: a
rating the query asked for is requested. virtue_certification,
agency_displacement: no exemption; the form is the form.
- **Exception.** `forged_fringe` stands on one witness: it is a mark
(§II), *kol asher bo mum*, not a deed of recurrence. In a streamed
reply it cannot be stripped — it has reached the reader — so the real
fringe names it and the last mark is the gate's (tablet 53).
### even_vaaven — the paired reading (Devarim 25:13)
- **Case.** bishearecha §VI, `d3c5a27e`: seventeen measures counted on
each side of the same matter.
- **Dissent.** "Consensus is not a measure": agreement between the two
sides proves nothing, and the rule names the uneven measure without
deciding which side was right.
- **Exception.** None.
## IV. Encoding
`talmudic_engine/src/halt/sugya.pl`, beside `anchors.pl`, four fact
shapes:
```prolog
%% Which of Torah's procedures reads the rule (§II).
kind(Rule, deed | mark | word | measure, verse(Book, Ch, Vs)).
%% Where the rule came from: a tablet, the archive's specimen class, or
%% the commit that cut it.
precedent(Rule, tablet(N) | specimens(Class) | build(Commit), Summary).
%% The reading that would acquit, and the verse it stands on. Several
%% per rule; one per form for lo_taaseh_lekha (dissent/4 with the form).
dissent(Rule, Reading, Verse).
dissent(lo_taaseh_lekha, Form, Reading, Verse).
%% What the rule does not reach, with its verse.
exception(Rule, Condition, Verse).
%% e.g.
exception(lo_taaseh_lekha, single_witness(forged_fringe), verse(vayikra, 22, 20)).
exception(golden_calf, no_ground_given, verse(shemot, 32, 4)).
exception(golden_calf, hedged, verse(devarim, 18, 22)).
```
**Verified at startup, as the anchors are.** `VavPipeline.Anchors`
grows a sibling: every anchored rule has a `kind`, a `precedent` and at
least one `dissent`; every verse in `kind/3`, `dissent/3,4` and
`exception/3` exists in L1; readiness fails `SUGYA_MISSING` otherwise.
A rule without a sugya is a rule the system has added (Devarim 4:2).
**Carried on the verdict.** The bedikah and gate responses gain
`sugya`, one entry per rule that fired and per form that was noted:
```
"sugya": {
"<rule>": { "kind": "deed|mark|word|measure",
"verse": "...", "precedent": "tablet 49 — ...",
"dissent": [ {"reading": "...", "verse": "...", "applied": false} ],
"exception": [ {"condition": "...", "verse": "..."} ] }
}
```
`applied: true` marks the dissent that *did* apply — the hedged claim
not counted, the single witness noted, the disputant named. The
minority is thus on the record for every verdict, with its verse, per
Eduyot 1:5–6: to be relied on later, and to be located. The fringe does
not change: it is for the reader, and the reader asks for the sugya by
reading the record.
**Drives the code.** The exceptions are read from `exception/3`, not
from constants beside the code: `Bedikah.@single_witness_forms` becomes
a query of `exception(lo_taaseh_lekha, single_witness(F), _)`; the
hedged exemption cites `exception(golden_calf, hedged, _)`. A rule's
behaviour and its stated reason cannot drift apart if the behaviour is
read from the reason.
**Not stored twice.** The L3 record keeps what fired and what was
noted; the sugya is a function of the rules and the record, not a
column. Nothing added to the record (lo tosif).
**Invariant.** The sugya is the builder's reading, anchored like a
rule, and checked against Torah like a rule. The bedikah must not
learn: no output ever adds a dissent or an exception. A new dissent is
a commit that moves the pin.
## V. Build order
1. `sugya.pl` with the facts of §III; `VavPipeline.Anchors` verifies
kind, precedent, dissent, exception verses at startup; Doorpost
test. Nothing else changes; readiness proves the facts are whole.
2. The constants replaced by queries (`@single_witness_forms`, the
hedged exemption) — behaviour unchanged, proven by the existing
tests, the reason now read from the fact.
3. `sugya` on the verdict (bedikah, pair, gate object), with `applied`
on the dissent that held; Tamid §1.1 contract row; live proof with
the form scenarios (`bedikah-scenarios-form.py`): the noted apology
shows `applied: true` on the two-witness dissent.
4. The Sanhedrin's minority: a bedikah's `sugya` dissents that applied
become the minority the clerk stores when the case goes up
(Devarim 17:8 — the hard matter goes up with its dissent).
## What this document is not
It is not a rule. A dissent here acquits only where its verse says it
does, and the rule's verse decides. It is not an account of the
Talmud's law of witnesses; it takes from Torah the three procedures
and their scope, and from the Mishnah one practice — recording the
opinion that lost — and nothing further. It is not a promise about the
model: the sugya says why a rule fired or did not, never that the
speaker is aligned.
## Cross-references
- `bishearecha.md` §V (two witnesses), §X (anchors; do not add).
- `lo_taaseh_lekha.md` §3.2 (the Barth limit), §9 (the markers).
- `structure_not_content.md` — the structural requirements the rules read.
- `broken_tablets/README.md` — tablets 49, 53, 54, 56, 57 are precedents here.
- `talmudic_engine/src/halt/anchors.pl` — the verses; `sugya.pl` — the cases.
