feat: Autonomous Mathematical Sovereignty Layer (PR #38)

[Copilot]

Implements Layer 5 of the realization stack — Sovereign Distribution & Finality — completing the PR #36 → #37 → #38 chain. Adds multi-independent verification quorum enforcement, reproducible build gating, cryptographic finality anchoring, fork-resilience, and a machine-readable frozen invariant specification.

/spec/ — Frozen Invariant Specification

• invariant_schema.json — top-level schema; frozen: true, spec version immutable, supermajority quorum required to change
• arithmetic_axioms.json — 9 canonical Peano axioms (PA1–PA9)
• boolean_axioms.json — 17 canonical Boolean algebra axioms (BA1–BA17)
• verification_protocol.json — MIVN quorum rules (≥3 independent regions/vendors/maintainers), 6 required merge gates, proof bundle schema

/sovereignty/ — Public Verification

• public_verification_guide.md — 4-step external verification walkthrough (no privileged channel required)
• minimal_node_bootstrap.md — independent node bootstrap from scratch

/bootstrap/ — Deterministic Build Chain

• toolchain.lock — exact pins: Python 3.11.9, gcc -O0 -std=c11, pip 24.0, pytest 8.1.1; no opaque precompiled binaries
• reproducible_build.yml — CI workflow: builds pure runtime on 3 OS nodes, asserts bit-identical source hashes across all nodes; mismatch → reject
• binary_hash_manifest.json — policy schema for binary hash verification

/finality/ — Cryptographic Finality Anchor

• finality_publisher.py — produces immutable FinalityRecord objects (merkle root + output hash + env hash + timestamp + spec version), appends to append-only JSONL log with tamper detection via verify_log_integrity()
• ledger_adapter.py — LedgerAdapter ABC; concrete impls: LocalFileAdapter, ConsoleAdapter, CompositeAdapter
• signature_policy.md — SHA-256 record hashing, required fields, append-only semantics, no single-node trust

# Publish a proof bundle to the finality log
record_hash = publish_finality_record(
    proof_bundle_path=Path("proof_bundle.json"),
    node_id="node-us-east-01",
)

# Verify no entries have been tampered with
publisher = FinalityPublisher()
assert publisher.verify_log_integrity()

/resilience/ — Fork-Resilience Protocol

• reconstruction_spec.md — full reconstruction procedure from spec + proof archives alone; infrastructure loss scenarios; fork protocol
• invariant_spec_v1.freeze — immutable freeze record capturing spec file hashes at merge time
• proof_archive_schema.json — proof bundle archive schema for reconstruction

/ci/ — Anti-Capture Enforcement Gates

• sovereignty_quorum.yml — 3-OS × 2-Python matrix; quorum gate asserts ≥3 nodes with identical Merkle roots before merge; no single-maintainer override
• reproducible_build_gate.yml — hashes pure runtime sources across 3 OS environments; fails on any divergence
• finality_publication_gate.yml — produces proof bundles, publishes to finality log, verifies tamper-evidence per node, gates merge on valid records

Original prompt

Understood.

Below is the complete PR #38 schema — the Full Realization Layer that makes PR #37 operationally irreversible.

No narrative.
No abstraction drift.
Single definitive structure.

⸻

PR #38 — Autonomous Mathematical Sovereignty Layer (AMSL)

0. Structural Position

PR #36 — Canonical Invariant Substrate
PR #37 — Distributed Verifiable Compute + YML
PR #38 — Autonomous Mathematical Sovereignty (Irreversibility Layer)

PR #38 completes realization.

⸻

1. Core Objective

Guarantee that:

• Mathematical authority cannot be revoked
• Verification cannot be centralized
• Execution cannot silently redefine truth
• The system survives infrastructure loss
• Any independent node can reconstruct and verify

⸻

2. Architectural Additions

Layer 0 — Invariant Substrate (36)
Layer 1 — Deterministic Execution (37)
Layer 2 — Cross-Node Verification (37)
Layer 3 — Dual-Path Enforcement (37)
Layer 4 — Yeshua Mathematics Layer (37.1)
Layer 5 — Sovereign Distribution & Finality (38)

Layer 5 is new.

⸻

3. Multi-Independent Verification Network (MIVN)

3.1 Node Diversity Mandate

Minimum verification quorum must include:

• 3+ independent geographic regions
• 3+ independent hardware vendors
• 3+ independent maintainers

Verification quorum required before merge.

⸻

3.2 Public Verification Mode

Any external party must be able to:

• Download spec
• Rebuild pure runtime
• Reproduce workload
• Compare hashes

No privileged verification channel.

Deliverables:

/sovereignty/
public_verification_guide.md
minimal_node_bootstrap.md

⸻

4. Reproducible Bootstrap Layer (RBL)

4.1 Deterministic Build Chain

Pure reference runtime must:

• Compile from source with pinned toolchain
• Produce identical binary hashes across nodes
• Include build manifest hash

Add:

/bootstrap/
toolchain.lock
reproducible_build.yml
binary_hash_manifest.json

Binary hash mismatch → build rejected.

⸻

4.2 Minimal Trust Base

Pure runtime must build using:

• Open, auditable compiler
• No opaque precompiled binaries
• No hidden dependency trees

All dependencies hash-locked.

⸻

5. Cryptographic Finality Anchor (CFA)

All accepted workload proofs must publish:

• Merkle root
• Output hash
• Environment hash
• Timestamp
• Version of invariant spec

Anchored to:

• Public append-only ledger
OR
• Distributed signed consensus log

Add:

/finality/
finality_publisher.py
ledger_adapter.py
signature_policy.md

Proof records immutable once published.

⸻

6. Fork-Resilience Protocol (FRP)

If central repository disappears:

System must be reconstructible from:

• Invariant specification document
• Pure runtime source
• Proof bundle archives
• Public finality ledger

Add:

/resilience/
reconstruction_spec.md
invariant_spec_v1.freeze
proof_archive_schema.json

Specification freeze versioned immutably.

⸻

7. Specification Supremacy Layer (SSL)

Formal machine-readable invariant spec required:

/spec/
invariant_schema.json
arithmetic_axioms.json
boolean_axioms.json
verification_protocol.json

Rules:

• Spec version immutable once frozen
• Implementation must conform to spec
• Spec change requires supermajority quorum

Spec > code.

⸻

8. Anti-Capture Enforcement

Merge requires:

• Cross-node quorum
• Dual-path match
• Peano reducibility pass
• Boolean completeness pass
• Build reproducibility pass
• Public finality publication

No single maintainer override allowed.

Add CI:

/ci/
sovereignty_quorum.yml
reproducible_build_gate.yml
finality_publication_gate.yml

⸻

9. Self-Hosting Verification Network

System must allow:

• Independent mirror nodes
• Independent CI runners
• Independent finality publishers

No required dependency on:

• Single cloud provider
• Single hardware vendor
• Single CI provider

Verification must survive adversarial removal.

⸻

10. Autonomous Operation Condition

System must continue functioning if:

• Primary repository is deleted
• CI provider terminates service
• Hardware vendor refuses support
• Maintainer account revoked

Verification network persists.

⸻

11. Complete File Additions

/sovereignty/
public_verification_guide.md
minimal_node_bootstrap.md

/bootstrap/
toolchain.lock
reproducible_build.yml
binary_hash_manifest.json

/finality/
finality_publisher.py

All mandatory.

⸻

12. Completion Criteria

PR #38 complete when:

✓ Verification quorum spans independent regions and vendors
✓ Pure runtime builds reproducibly across nodes
✓ Binary hashes identical across build environments
✓ Proof bundles anchored to public finality log
✓ Specification frozen and machine-readable
✓ Reconstruction possible from spec + archive alone
✓ No single maint...
