Verified live 2026-10-19: Tamid's own example for POST /chatzer/sanhedrin
(a case with `sides`) answered 500. The router passed the sides LIST as
the case context; halt_monitor:check_avodah_zarah/1 reads a map, maps:get
raised, and the halt monitor and escalation gen_servers died with the
caller's input (supervisor restarted them; health stayed 8/8). The router
then matched {:ok, decision} on the error and made a 500 of its own.
- sanhedrin/src/halt_monitor.erl: do_check_case refuses a non-map
context as {halt, malformed_case, _} and stays standing. EUnit 49/0
with the new halt_malformed_context_test.
- router.ex process_sanhedrin: sides validated at the kiyor (422 on a bad
shape), carried as context %{sides: sides}; a Sanhedrin refusal answers
422 SANHEDRIN_HALTED, a failure 503 SANHEDRIN_UNAVAILABLE. Two new
router tests, one asserting the gate processes survive the example.
Elixir 624/0.
- specs/broken_tablets/README.md: tablet 55, including what is NOT fixed
— a panel of one accepting on zero references under a grounded-
sounding sentence, the ignored complexity hint, no panel manna spent,
no L3 record. The row in Tamid is still larger than the thing behind it.
Doorpost pin unchanged (no @spec_files touched; scripts/doorpost_check.py
passes).

Closes F1–F7 from the conversation-history review at
~/shorashim-conversation-review.md, per the Torah ruling for Option 2:
Devarim 12:13–14 — לֹא תַעֲלֶה עֹלֹתֶיךָ בְּכָל מָקוֹם אֲשֶׁר תִּרְאֶה
כִּי אִם בַּמָּקוֹם אֲשֶׁר יִבְחַר ה׳ ... שָׁם תַּעֲשֶׂה כֹּל
אֲשֶׁר אָנֹכִי מְצַוֶּךָּ.
The offering happens in one place. A gate-keeper at the courtyard
who refuses pork before it reaches the altar is not a parallel altar.
Devarim 13:1 — לֹא תֹסֵף עָלָיו וְלֹא תִגְרַע מִמֶּנּוּ.
The interface remains; no parallel detection authority is added.
The previous halt_monitor.erl claimed to mirror the Talmudic Engine
halt modules (Prolog) and the Vav Pipeline halt_conditions (Elixir),
but in practice it was a partial sketch with stub checks, no read API,
verb-only shfichut_damim that would fire on log rotation, and a
"cannot be bypassed" claim that the implementation didn't deliver.
The docstring overstated. Eish zarah by the repo's own definition —
real Erlang, sincerely written, but אֲשֶׁר לֹא צִוָּה אֹתָם.
Changes:
sanhedrin/include/sanhedrin.hrl
- Document the halt-relevant context keys explicitly
(authority_source, action, boundary_violation) — closes F1.
These keys were used by halt_monitor and the test suite but
were not in the .hrl record commentary. Interface drift fixed
by writing down the actual contract.
sanhedrin/src/halt_monitor.erl
- Re-framed as "Sanhedrin's gate-keeper": local courtyard refusal,
not parallel altar. Honest docstring.
- When the gate detects a halt, FORWARDS the canonical halt event
to VavPipeline.HaltMonitor.halt!/3 (single source of truth).
Best-effort: if Elixir module isn't loaded, local refusal still
works.
- Export audit_log/0 and halt_count/0 — closes F6 (was write-only
from outside the module).
- Remove process_flag(trap_exit, true) and the dead
handle_info({'EXIT', _, _}, _) clause — closes F7 (nothing was
ever linked).
- Remove unused check_authority_in_text/1 stub from the call chain
— closes F5. do_check_vote/1 now documents that vote-text
inspection is the upstream pipeline's responsibility.
- check_gilui_arayot/1 docstring now states truthfully: detection
of WHETHER an action collapses a distinction lives in
talmudic_engine/src/halt/gilui_arayot.pl; this gate reads the
flag — closes F2 framing.
- check_shfichut_damim/1 docstring now states: conservative
gate-keeper, fail-closed; the canonical tzelem-target check
lives in talmudic_engine/src/halt/shfichut_damim.pl — closes
F3 framing.
- "Cannot be bypassed" claim removed; truthful description added:
"enforced by callers (escalation.erl checks the return value
before convening a panel)" — closes F4.
vav_pipeline/test/sanhedrin_halt_forwarding_test.exs (NEW)
- 6 integration tests proving the forwarding chain end-to-end:
halt_monitor.erl is loadable from the same BEAM VM, exposes
audit_log/0 and halt_count/0 (F6 verification), and on each of
the three cardinal sin types fires HaltMonitor.halt!/3 with
component="sanhedrin/case". Verified that VavPipeline.HaltMonitor.
halted?/0 flips to true after each gate refusal and the event's
.condition matches the gate's halt type.
The local audit log on the gate-keeper is preserved (the Sanhedrin
operator can still see what was refused at the gate). The system-wide
halt audit lives in VavPipeline.HaltMonitor.audit_log/0 — one altar.
Existing 12 sanhedrin EUnit tests of the gateway behavior continue
to pass (verified via mix deps.compile sanhedrin — clean compile).
The 6 new Elixir-side integration tests pass (verified).
Test counts:
- Elixir: 280 (was 274; +6 new forwarding tests), 0 failures attributable
to this change. (3 pre-existing time-dependent test failures in
step31_shema_test.exs occur on Shabbat — system correctly returns
cloud_state == {:major_transition, :shabbat_rest, _} when run after
Friday sundown; tests assert :camped. Not caused by this change.)

Zerikah fail-safe: empty offerings rejected, not processed (BUILD_KORBAN §5).
Halt monitor hardened: trap_exit, priority max, EXIT handler (Architecture spec).
13 Rules of Rabbi Yishmael added to Architecture §3.4 as Prolog inference predicates —
the engine reasons WITH Torah's hermeneutic methods, not just about their products.
