ZAKON #18B — Blueprint Liveness Enforcement
ZAKON #18B — Blueprint Liveness Enforcement
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 < 5/5 or last-verified > 30d
Registry Gate (Track 5d #100464)
ZAKON Registry blocks new zakon-*.md files without [CEO_APPROVED] token + MC reference in zakon-registry.json.

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.
