MoCKA Transparency — Tamper Detection Layer

This is not a security scanner. Not a firewall. Not an access control system. It is the layer that proves nothing has been altered — cryptographically, independently, and publicly.

Not "trust us." "Verify yourself."

Position in mocka_Movement

``` MoCKA (core · heart) ↓ mocka-knowledge-gate ② Record ↓ [ mocka-transparency ] ← ③ Incident · ④ Recurrence — YOU ARE HERE ↓ mocka-external-brain ⑥ Decision ↓ mocka-civilization ⑧ Institutionalize ```

Loop step: ③ Incident · ④ Recurrence Upstream: mocka-knowledge-gate → sends sealed records Downstream: mocka-external-brain → receives verified findings

What this repository does

mocka-transparency provides cryptographic proof that every record is authentic.

• Ed25519 digital signatures — every governance event is signed
• SHA256 hash chain — append-only, tamper-evident history
• Public verification — anyone can verify, no trust required
• Tamper detection — even one byte changed is detected

If anything was altered — the system detects it. If the chain is intact — the system proves it.

shadow_Movement and transparency

Primary path fails
      ↓
shadow_Movement activates
      ↓
mocka-transparency preserves the evidence
      ↓
Failure is recorded · analyzed · institutionalized
      ↓
The civilization loop continues

shadow_Movement is not a backup. mocka-transparency ensures the evidence survives even when the primary path fails.

Quick Start

# Verify the hash chain
python verify_chain.py
# → CHAIN OK

# Run all governance checks
python verify_all.py
# → ALL CHECKS PASSED

# Demonstrate tamper detection
.\tamper_demo.ps1

Status

MoCKA Transparencyとは何か

セキュリティスキャナーではありません。ファイアウォールでもありません。 何も改ざんされていないことを暗号的に・独立して・公開可能な形で証明する層です。

「信頼してください」ではなく「自分で検証してください」。

mocka_Movementにおける位置づけ

MoCKA（コア・心臓部）
      ↓
mocka-knowledge-gate       ② Record
      ↓
[ mocka-transparency ]     ← ③ Incident · ④ Recurrence — ここです
      ↓
mocka-external-brain       ⑥ Decision
      ↓
mocka-civilization         ⑧ 制度化

ループステップ：③ Incident · ④ Recurrence 上流：mocka-knowledge-gate → 封印済み記録を送信 下流：mocka-external-brain → 検証済み知見を受信

このリポジトリの役割

すべての記録が本物であることを暗号的に証明します。

• Ed25519デジタル署名 — 全ガバナンスイベントが署名済み
• SHA256ハッシュチェーン — 追記専用・改ざん検知可能な履歴
• 公開検証 — 誰でも検証可能・信頼不要
• 改ざん検知 — 1バイトでも変更があれば検出

shadow_Movementとの関係

shadow_Movementはバックアップではありません。 mocka-transparencyは主系が停止しても証拠を保全し、 文明ループが継続することを保証します。
