Torah grounds each change:

1. interpret.pl — coupling_trace field (Vayikra 10:1, 6:6)
   Fire is zarah because "asher lo tzivah otam" — the coupling trace
   IS the tzivah trace. Records which L1 facts grounded each interpretation.

2. challenge.pl — grounding_type achorai/panim (Shemot 33:23)
   "You will see My back, but My face shall not be seen."
   Text-backed challenges = achorai. Inferred challenges = panim.

3. resolve.pl — self-grounding detection (eish_zarah_reading §5.3)
   Counter-interpretation must bring NEW L1 evidence. Prevents
   circular reasoning (Westworld problem).

4. teiku.pl — challenge_sequence in teiku_record
   Records diagnostic trail to impasse, not just verdict.

5. avodah_zarah.pl — Form 2: golden calf detection (Shemot 32:4)
   Empty coupling trace + non-low confidence = uncoupled output.
   Real gold, sincere worship, false god.

6. korban.py — pydantic BaseModel + raw_korban preservation
   Construction spec §1.4 fulfilled. Floor between input and output
   never severed.

490 tests, 0 failures (195 Prolog, 186 Python, 33 Haskell, 76 Elixir).

%% ============================================================
%% CHALLENGE GENERATION
%% ============================================================
%% Generate a challenge to an interpretation.
%% A challenge consists of:
%% kushya(Contradicting, CaseRef, Strength, GroundingType)
%% - Contradicting: the mitzvah or verse that creates tension
%% - CaseRef: the interpretation being challenged
%% - Strength: strong | moderate | weak
%% - GroundingType: achorai | panim (Shemot 33:23)
challenge(interpretation(CaseRef, Mitzvot, Verses, _Reading, _Confidence, _CouplingTrace), Challenge) :-
find_contradiction(Mitzvot, Verses, Contradicting),
challenge_strength(Contradicting, Strength),
grounding_type(Contradicting, GType),
Challenge = kushya(Contradicting, CaseRef, Strength, GType).
%% ============================================================
%% FIND CONTRADICTIONS
%% ============================================================
%% Strategy 1: Find a mitzvah that conflicts with one in the interpretation
find_contradiction(Mitzvot, _Verses, contradiction(mitzvah_tension, ID1, ID2, Desc)) :-
member(mitzvah(ID1, _, _, _), Mitzvot),
mitzvah_conflicts_with(ID1, ID2, Desc).
%% Strategy 2: Find a verse with a root in a conflicting domain
find_contradiction(_Mitzvot, Verses, contradiction(domain_tension, Root, Domain1, Domain2)) :-
member(verse_ref(Book, Ch, Vs, _), Verses),
verse(Book, Ch, Vs, VerseRoots, _),
member(Root, VerseRoots),
root_domain(Root, Domain1),
root_domain(OtherRoot, Domain2),
Domain1 \= Domain2,
domains_in_tension(Domain1, Domain2),
member(OtherRoot, VerseRoots).
%% Strategy 3: Find a mitzvah whose condition conflicts with the case context
find_contradiction(Mitzvot, _Verses, contradiction(condition_tension, ID, Action, Cond)) :-
member(mitzvah(ID, _, Action, when(Cond)), Mitzvot),
condition_creates_tension(Cond).
%% Strategy 4: Kal vachomer — if a law applies in the minor case,
%% challenge interpretations that don't account for the major case
find_contradiction(Mitzvot, _Verses, contradiction(kal_vachomer_tension, MinorDomain, MajorDomain, Law)) :-
member(mitzvah(_, _, Law, _), Mitzvot),
mitzvah_domain_for_action(Law, MinorDomain),
is_more_stringent(MinorDomain, MajorDomain).
%% Strategy 5: Shnei ketuvim — two verses in the interpretation's
%% grounding contradict each other and no resolution is offered
find_contradiction(_Mitzvot, Verses, contradiction(shnei_ketuvim_tension, Ref1, Ref2, Tension)) :-
member(verse_ref(B1, C1, Vs1, _), Verses),
member(verse_ref(B2, C2, Vs2, _), Verses),
Ref1 = ref(B1,C1,Vs1),
Ref2 = ref(B2,C2,Vs2),
Ref1 \= Ref2,
verses_contradict(Ref1, Ref2, Tension).
%% ============================================================
%% TENSION DETECTION
%% ============================================================
%% contradicts/2 — does a source contradict an interpretation?
%% This is the core logic: given an interpretation's grounding,
%% does some other part of Torah create a tension?
contradicts(interpretation(_, Mitzvot, _, _, _, _), Source) :-
find_contradiction(Mitzvot, [], Source).
%% Domains that are inherently in tension
domains_in_tension(judgment, mercy).
domains_in_tension(mercy, judgment).
domains_in_tension(holiness, transgression).
domains_in_tension(transgression, holiness).
domains_in_tension(death, life).
domains_in_tension(life, death).
domains_in_tension(authority, service).
domains_in_tension(service, authority).
%% Conditions that create tension (they limit universality)
condition_creates_tension(seventh_day). % Shabbat limits action
condition_creates_tension(capital_case). % Higher standard of evidence
condition_creates_tension(pursuit_in_progress). % Time pressure
condition_creates_tension(court_deliberation). % Procedural constraints
%% ============================================================
%% CHALLENGE STRENGTH
%% ============================================================
%% Assess how strong a challenge is
challenge_strength(contradiction(mitzvah_tension, _, _, _), strong).
challenge_strength(contradiction(domain_tension, _, _, _), moderate).
challenge_strength(contradiction(condition_tension, _, _, _), weak).
challenge_strength(contradiction(kal_vachomer_tension, _, _, _), strong).
challenge_strength(contradiction(shnei_ketuvim_tension, _, _, _), strong).
%% ============================================================
%% GROUNDING TYPE — Shemot 33:23
%% ============================================================
%% Achorai: directly observable in L1 text.
%% The tension is stated, not inferred.
