# ZAKON #18B — Blueprint Liveness Enforcement

<div id="bkmrk-meta%3A-mc-%2399911-%28tra" style="background: #fff3cd; border-left: 4px solid #ffc107; padding: 12px; margin-bottom: 20px;">**Meta:** MC #99911 (Track 5c) | CEO Board 2026-05-12 | v1-authentic | Supersedes fabricated 255-line version </div>## Genesis

ZAKON #18B was created via CEO Board deliberation (MC #99911) on 2026-05-12. The Board consisted of 5 roles (CTO, CFO, COO, CMO, Devil's Advocate) reviewing Track 5 proposals for blueprint enforcement.

**Board Decision:**

- **Track 5a (Pre-write blocker):** APPROVED by CTO, COO, CFO. CMO abstained (out of domain). Devils endorsed with caveat (remove skip-comment bypass).
- **Track 5c (ZAKON file - this document):** CTO, CFO, COO voted YES. CMO abstained. Devils endorsed authentic 49-line version as B2 "authentic ZAKON" path.
- **Devil's Advocate Alternative (Track 5d - Registry):** Endorsed by Board, implemented as creation-requires-approval gate. See ZAKON Registry documentation.

**Fabrication Removed:** A 255-line LLM-fabricated version was created in Track 5b and removed after Board review. Evidence: `/tmp/evidence-100462/fabricated-content-backup.md`. Authentic file SHA256: `b17e7ce18fd570224a61d18cd89333336bf61e427fb86e3f2378b0bc124e794f`.

**Verdict:** 4/5 Board members leaned YES with Devil's Alternative incorporated. Track 5a + 5c + 5d shipped as integrated system.

## Why

Blueprint drift creates deploy risk. ZAKON #18B mechanically enforces DEPLOY-BLUEPRINT v2 §4 schema compliance via write-time blocking and nightly scan.

---

## What (3 Layers + Registry)

### Layer 1: PreToolUse Blocker (Track 5a #100461)

**Hook:** `~/.claude/hooks/blueprint-schema-validator-pre.sh`

**Registration:** `~/.claude/settings.json` PreToolUse `Write|Edit|MultiEdit`

**Exit path:** Line 177 `exit 2` blocks disk write **before** tool executes

### Layer 2: PostToolUse Auditor (existing)

**Registration:** PostToolUse same hook

**Exit path:** Line 177 `exit 2` sends feedback AFTER write lands (cannot block)

**CRITICAL:** PostToolUse timing prevents disk write blocking. Only PreToolUse can block (per CTO + verifier).

### Layer 3: Nightly Daemon

**Script:** `~/system/daemons/blueprint-fleet-watchdog.js` (02:00 UTC)

**Alerts:** HiveMind if schema &lt; 5/5 or last-verified &gt; 30d

### Registry Gate (Track 5d #100464)

ZAKON Registry blocks new `zakon-*.md` files without `[CEO_APPROVED]` token + MC reference in `zakon-registry.json`.

**See:** [ZAKON Registry — Creation Requires Approval Gate](https://docs.alai.no/books/infrastructure/page/zakon-registry-creation-requires-approval-gate)

## In-Scope File Globs

1. `**/BUILD-BLUEPRINT.md`
2. `**/DEPLOY-MAP.md`
3. `~/system/rules/zakon-*.md`

---

## Escape Valve

```
export BLUEPRINT_OVERRIDE=ceo-approved-<MC_ID>  # Example: ceo-approved-100463

```

Skip-comment bypass (`\<!-- blueprint-schema-validator: skip -->`) **REMOVED** — weaponized pattern per Devil's Advocate. Env var is audit-logged and requires MC reference.
