Steps 30-32: Sanhedrin stress test, Shema test suite, full system verification

Shemot 39:43 — Vayar Moshe et kol ham'lakhah v'hineh asu otah
ka'asher tzivah Hashem ken asu, vayevarekh otam Moshe.

Step 30 — Sanhedrin stress test:
- 10 rapid submissions without crash
- Case ref preservation across decisions
- Rich context handling at simple complexity
- Decision structure consistency (7 required fields)
- Graceful degradation when Sanhedrin unavailable
- 20 concurrent Task.async submissions

Step 31 — Shema Test suite (Architecture §6.3, five tests):
1. Te'amim reception: raw cantillation from L1, etnachta detection,
   L1→ShemaContext fidelity, surprising etnachta position
2. Ketiv/qere preservation: field exists, survives full pipeline
3. Cloud obedience: :camped allows processing, Shabbat triggers
   major_transition, context immutability under override
4. Manna fidelity: no provision → {:waiting, :no_provision},
   provision present → processing proceeds, MannaLedger tracks
5. Context immutability: context unchanged after pipeline,
   keys stable, each stage receives same context

Step 32 — Full system verification (kol ham'lakhah):
- Full pipeline: Shema → BereishitCycle → output, multi-verse
- Halt conditions: check_all processes output
- Protection layer: AreiMiklat refuge→release, EglahArufah
  declaration, Bikurim first-output review
- Chatzotzrot: subscribe→signal→receive→zikaron, routing isolation
- MannaLedger: load→consume→boundary cycle
- L1 integrity: hash valid, 5 core verses readable, roots present
- Supervision tree: all 7 GenServers running
- Cross-component: ShabbatTimer reads cloud, Shema builds from
  L1+Cloud+Manna

All 206 Elixir + 19 L3 + 195 Prolog + 33 Haskell = 434+ tests, 0 failures
