Add Second Trust Deed: Recursive Digital Twin Verification

- SECOND_TRUST_DEED.md: 9 articles governing deterministic build through twin simulation
- Security Twin: detects eval, exec, secrets, XSS, weak randomness
- Logic Twin: validates RTRUST rules, detects missing principles, duplicates
- Performance Twin: detects infinite loops, uncaught JSON.parse, sync I/O
- Orchestrator: runs all 3 twins in parallel, detects disagreements
- Reverse Engineering Proof: maps artifacts back to instructions, clauses, agents
- Failure Loop: 7-question manifestation before approval
- Repentance Cycle: controlled reconstruction with WORM sealing
- 49/49 tests passing
- 25/25 doctor checks passing

+# SECOND TRUST DEED: RECURSIVE DIGITAL TWIN VERIFICATION
+
+## Article I — Deterministic Build Covenant
+
+This Trust Deed establishes that no agent-generated code may be treated as complete merely because it compiles, runs, or appears functional.
+
+All generated systems must pass through recursive digital twin simulation before promotion.
+
+The model may generate.
+
+The twins must inspect.
+
+The deed must govern.
+
+The WORM chain must remember.
+
+---
+
+## Article II — Cold Boot Requirement
+
+Every production candidate must begin from a cold boot state.
+
+A cold boot means:
+
+1. No inherited assumptions.
+2. No hidden runtime state.
+3. No unverified memory.
+4. No prior approval carried forward.
+5. No agent authority assumed without deed validation.
+
+The system must reconstruct the build from first principles before execution.
+
+---
+
+## Article III — Reverse Engineering Proof
+
+After generation, the system must reverse-engineer its own output.
+
+The purpose is not style review.
+
+The purpose is traceability.
+
+Every produced artifact must be mapped back to:
+
+* the originating instruction,
+* the active Trust Deed clause,
+* the agent that produced it,
+* the state transition that authorized it,
+* the WORM event that sealed it.
+
+If the generated code cannot be explained by the Trust Deed, it is rejected.
+
+---
+
+## Article IV — Async Parallel Digital Twin Spans
+
+Every build must be audited by parallel digital twins.
+
+### Twin A — Security Twin
+
+Audits vulnerabilities, secrets, unsafe execution paths, authentication gaps, authorization flaws, injection surfaces, and supply-chain risks.
+
+### Twin B — Logic Twin
+
+Audits internal consistency, theological alignment where applicable, Lean/RTRUST compliance, contradiction, false attribution, and invalid reasoning chains.
+
+### Twin C — Performance Twin
+
+Audits resource usage, latency, scaling limits, memory pressure, failed queues, race conditions, and production reliability.
+
+The twins may run asynchronously.
+
+They may disagree.
+
+Disagreement must be logged, not hidden.
+
+---
+
+## Article V — Failure Loop Manifestation
+
+Before final approval, the system must simulate its own failure.
+
+The failure loop must ask:
+
+1. What breaks first?
+2. What assumption fails?
+3. What agent overreaches?
+4. What trust boundary leaks?
+5. What state becomes stale?
+6. What WORM seal fails?
+7. What human would be harmed by this failure?
+
+If a failure is discovered, the system enters repentance.
+
+---
+
+## Article VI — Repentance Cycle
+
+Repentance is not punishment.
+
+Repentance is controlled reconstruction.
+
+When a twin detects failure:
+
+1. The failure is sealed.
+2. The violated clause is identified.
+3. The build is rolled back or patched.
+4. The agent must re-derive its reasoning.
+5. The twins re-audit.
+6. LEDGE appends the new result.
+
+No silent patching.
+
+No hidden correction.
+
+No unsealed retry.
+
+---
+
+## Article VII — Rebuild Authority
+
+A rebuild may occur only after:
+
+* Security Twin passes,
+* Logic Twin passes,
+* Performance Twin passes,
+* SENTINEL approves,
+* LEDGE seals,
+* the Trust Deed remains unchanged,
+* no agent weakened the rules to pass the test.
+
+If any agent modifies the constitution to make the build pass, the build is void.
+
+---
+
+## Article VIII — Legendary Loop
+
+The accepted loop is:
+
+```
+COLD BOOT
+↓
+TRUST DEED INVOCATION
+↓
+AGENT GENERATION
+↓
+REVERSE ENGINEERING PROOF
+↓
+PARALLEL DIGITAL TWIN AUDIT
+↓
+FAILURE LOOP MANIFESTATION
+↓
+REPENTANCE OR REBUILD
+↓
+SENTINEL APPROVAL
+↓
+LEDGE SEAL
+↓
+WORM APPEND
+↓
+PRODUCTION CANDIDATE
+```
+
+This is not vibe coding.
+
+This is deterministic systems engineering through recursive digital twin simulation.
+
+The LLM is the construction crew.
+
+The agents are the inspectors.
+
+The Trust Deed is the law.
+
+The WORM chain is the witness.
+
+---
+
+## Article IX — Prime Clause
+
+No agent may claim completion until the system has survived the failure it was most likely to hide.
+
+A build that cannot survive inspection is not a build.
+
+It is only a suggestion.
