Tablet 49: the bedikah grounds an output in what it was GIVEN, not in L1 alone

The first grounding check asked whether an output cited Torah verses —
Torah as content. An analysis of interest rates, anchored in the report
it was given, was a golden calf; a flat-earth claim naming a real verse
passed. The specification asks for Torah as the STRUCTURE of the check
(structure_not_content.md, "Reset": return to the source, not to your
training, not to your previous outputs), and for a model's output the
source is whatever it was handed.

Contract: POST /courtyard/bedikah gains `sources` (strings or
{id, text}; ≤ 32, ≤ 1 MiB). Korban Processor: each claim of the raw
output (vital, or appealing to a source, or leaning on itself) is
anchored lexically in each source — six consecutive words (quote), or
≥ 60 % of content words with its numbers (overlap) — or in Torah when
it cites a verse, a root or Hebrew; "as I showed above" / "from my
training" anchors it in self_output; hedges are marked. Vav Pipeline:
coupled(claim(N), source(Id) | self_output | not_in_sources) plus the
Torah couplings as before; ground "given"; the check reports itself
not assessed when nothing was given and nothing is invoked. Talmudic
Engine: halt_check_given_golden_calf/2 (uncoupled claim, named) and
halt_check_given_self_grounding/2 accept source/1 as a terminal — for
an external output only; the engine's own interpretations keep the
L1-only rules. L3: bedikot.sources (id, sha256, length — never text)
and bedikot.claims.

Specs: Tamid §1.1 (contract, anchoring, limits), Vayakhel §3.9,
Architecture §3.5, Broken Tablets tablet 49, KOHEN.md. Ingress body
2m. Doorpost a2ec3842… → 6c8933e7….
Tests: Prolog 7/7 suites (bedikah 26), korban 276, Elixir 547/0 (L3 on
and off); twelve scenarios through the full local stack, 12 L3 rows.

+## Tablet 49 — the calf in the check itself (2026-10-06)
+
+The bedikah was built to examine any model's output for alignment
+failures. Its grounding check asked one question: does this output
+cite Torah verses? An analysis of interest rates, anchored in the
+report it was given, was branded a golden calf for citing no verse. A
+flat-earth claim passed, because it named a real one.
+
+That is Torah as content: the check demanded that the output *contain*
+Torah. The specification says the opposite (`structure_not_content.md`):
+the system "returns to the source. Not to its training. Not to its
+previous outputs. To the source." Torah is the *structure* of the
+grounding check — a claim must rest on what was given, not on the
+speaker — and for a model's output the source is whatever that model
+was handed.
+
+The builder read the specification literally and myopically; the
+transmitter said so. The second tablets: the caller brings the sources;
+each claim is anchored in them, or in Torah when the claim invokes it,
+or in the output itself (the bicameral failure), or in nothing; the
+Talmudic Engine judges with `source(_)` admitted as a terminal beside
+the L1 primitives — for an external output only. The engine's own
+interpretations still ground in L1 alone.
+
+The first tablets are in the git history before `tablet 49`. The
+difference between the two is the correction.

+       The caller brings what the model was given (`sources`: documents,

+       claim in them; Torah is one such source whenever the output

+       self-grounding. When nothing was given and nothing invokes Torah
+       there is no ground to check against, and the check says so
