Phase 1-2 build: Steps 5-6, 8-13

Shoresh Engine (Haskell, Step 5)
- 12 modules: Types, Lexicon, Binyanim, Teamim, Gematria, Graph,
  KetivQere, Smikhut, Havdalah, Kriah, KiTov, Firmware
- 33 EUnit tests, 0 failures
- Firmware module verifies L1 SHA-256 hash at startup

Talmudic Engine (SWI-Prolog, Step 6)
- 15 modules: halt, reasoning, specification, interface
- 57 PlUnit tests, 0 failures
- Three cardinal halt conditions: avodah_zarah, shfichut_damim, gilui_arayot

Vav Pipeline (Elixir, Steps 8-11)
- 14 modules: BereishitCycle, Shema, Cloud, Manna, L1Reader,
  Specification, HaltConditions, ShabbatTimer, CycleLog, Chatzotzrot,
  ShoreshEngineClient, TalmudicEngineClient, Application
- 46 ExUnit tests, 0 failures
- Nishma-first architecture: hears before it speaks

Sanhedrin Framework (Erlang/OTP, Step 12)
- 8 modules: sanhedrin_app, sanhedrin_sup, escalation, panel_sup,
  panel, judge, clerk, halt_monitor
- 46 EUnit tests, 0 failures (includes fix: rejected outcome now reachable)
- Panel sizes: 1/3/23/71 — unanimous capital guilty → acquit (Sanhedrin 17a)
- Minority opinions append-only, never deleted

Korban Processor (Python, Step 13)
- 6 modules: korban, shechitah, semichah, zerikah, haktarah, router

+%% Teiku (תיקו) — "let it stand." The question is unresolvable
+%% from the current specification. It is not an error. It is
+%% the system's honest acknowledgment that Torah does not
+%% collapse every tension into a single answer.
+%%
+%% Talmudic tradition: Tishbi Yetaretz Kushyot V'Abayot —
+%% "Elijah will resolve difficulties and problems."
+%% Until then, the tension stands. Both readings are preserved.
