feat: integrate ECHIDNA neurosymbolic proof assistant

Phase 1 Integration:
- Add scripts/use-echidna.sh wrapper (list, suggest, complete, verify, repl)
- Add 6 justfile recipes for ECHIDNA operations
- Create ROADMAP-UPDATED.adoc (simplified 7-year plan)
- Create INTEGRATION-STATUS-2026-02-05.adoc (progress report)

Architecture Clarity:
- ECHIDNA runs as separate tool (not merged)
- Operates ON absolute-zero proofs (external assistance)
- 27 Admitted proofs identified (target: 0 for v1.0)

Next Steps:
- Use ECHIDNA to complete Admitted proofs
- Multi-prover consensus verification
- Container integration

+
+== Date: 2026-02-05
+
+== Tasks Completed
+
+=== ✅ 1. License Standardization
+
+**absolute-zero**:
+* Added LICENSE file (PMPL-1.0-or-later)
+* Updated README.adoc (removed AGPL references)
+* Fixed SPDX headers in all checkpoint files
+* Removed LICENSE-PALIMPS.md stub
+* Committed: cbeb34a
+
+**echidna**:
+* Updated Cargo.toml license field
+* Fixed 67 source file SPDX headers
+* Verified consistency across all files
+* Committed: 482892e
+
+**Status**: Both repos now consistently use PMPL-1.0-or-later ✅
+
+---
+
+=== ✅ 2. Roadmap Update
+
+**Created**:
+* `ROADMAP-UPDATED.adoc` - Clarified architecture
+* `PROOF-VS-TEST-SUBJECTS.adoc` - Explained proof systems vs. test languages
+* `LICENSE-AUDIT-2026-02-05.adoc` - Documented license migration
+
+**Key clarifications**:
+* ECHIDNA is a separate tool (not merged)
+* Python/npm are test subjects (not dependencies)
+* Proofs remain in Coq/Lean/Z3 (RSR-compliant)
+* v1.0 focuses on pure formal verification
+
+**Status**: Architecture documented, roadmap simplified ✅
+
+---
+
+=== ✅ 3. ECHIDNA Integration (Phase 1)
+
+**Infrastructure Setup**:
+* Built ECHIDNA from source (cargo build --release)
+* Created `scripts/use-echidna.sh` wrapper script
+* Added justfile recipes:
+  - `just echidna-list` - List Admitted proofs
+  - `just echidna-suggest <file>` - Get tactic suggestions
+  - `just echidna-complete <file>` - Auto-complete attempts
+  - `just echidna-verify` - Multi-prover verification
+  - `just echidna-repl` - Interactive REPL
+  - `just echidna-check` - Verify installation
+
+**Discovered**: 27 Admitted proofs (not 21 as initially estimated)
+
+**Files with Admitted**:
+* CNOCategory.v (3)
+* FilesystemCNO.v (6)
+* LambdaCNO.v (4)
+* MalbolgeCore.v (1)
+* LandauerDerivation.v (3)
+* StatMech.v (2)
+* QuantumCNO.v (5)
+* QuantumMechanicsExact.v (3)
+
+**Status**: Integration complete, ready for proof completion ✅
+
+---
+
+== Current State
+
+### Repository Health
+
+**absolute-zero**:
+* License: ✅ PMPL-1.0-or-later
+* Checkpoint files: ✅ Up to date
+* Documentation: ✅ Comprehensive (5 new docs)
+* ECHIDNA integration: ✅ Working
+* Proofs: ⏳ 27 Admitted remaining
+
+**echidna**:
+* License: ✅ PMPL-1.0-or-later
+* Build: ✅ Success (release mode)
+* Binary: ✅ ~/Documents/hyperpolymath-repos/echidna/target/release/echidna
+* Integration: ✅ Scripts created
+
+---
+
+## Next Steps (Immediate)
+
+### Week 1: Proof Completion Sprint
+
+1. **Target easy proofs first** (5-10 completable)
+   ```bash
+   just echidna-complete proofs/coq/common/CNO.v
+   # Review suggestions, integrate if valid
+   ```
+
+2. **Focus on StatMech.v** (2 Admitted)
+   - Bennett's theorem
+   - Logical reversibility
+
+3. **Incremental commits**
+   - Complete 1-2 proofs per day
+   - Cross-verify in Lean 4/Z3
+   - Update STATE.scm progress
+
+### Week 2: Multi-Prover Consensus
+
+```bash
+just echidna-verify  # Run consensus check
+# Fix any disagreements between provers
+```
+
+### Week 3-4: Container & CI
+
+* Build verification container
+* Automate proof checking
+* Pre-commit hooks
+
+---
+
+## Metrics
+
+### Proof Completion
+
+[cols="1,1,1"]
+|===
+|File |Admitted |Target
+
+|CNOCategory.v |3 |0
+|FilesystemCNO.v |6 |0
+|LambdaCNO.v |4 |0
+|MalbolgeCore.v |1 |0
+|LandauerDerivation.v |3 |0
+|StatMech.v |2 |0
+|QuantumCNO.v |5 |0
+|QuantumMechanicsExact.v |3 |0
+|**TOTAL** |**27** |**0**
+|===
+
+**Current completion**: 73% (estimated, based on ~100 total theorems)
+**Target completion**: 100% (v1.0 requirement)
+
+### Integration Quality
+
+* Scripts: ✅ 1 wrapper script
+* Justfile recipes: ✅ 6 commands
+* Documentation: ✅ 5 documents
+* License compliance: ✅ 100%
+* Architecture clarity: ✅ Documented
+
+---
+
+## Risk Assessment
+
+### Low Risk ✅
+* License migration - Complete
+* Documentation - Comprehensive
+* ECHIDNA build - Working
+
+### Medium Risk ⚠️
+* Proof completion time - 27 proofs may take >2 months
+* ECHIDNA accuracy - Need to validate suggestions carefully
+* Multi-prover disagreements - May require manual resolution
+
+### Mitigation
+* Start with easier proofs (build confidence)
+* Always manually review ECHIDNA suggestions
+* Use multi-prover consensus (3+ provers)
+* Document any proof challenges
+
+---
+
