Lesson E+B Hard Enforcement — PI Agent Plane (MC #103499)

Lesson E + B Hard Enforcement — PI Agent Plane (MC #103499) 
 Date: 2026-06-12
 Owner: John (orchestrator)
 Status: Implemented + Proveo-verified 
 Problem 
 Lesson E (credential-pair validation) and Lesson B (verify-by-live-outcome) were hard-enforced on the Claude Code (CC) plane via ~/.claude/hooks/cred-pair-gate.sh (PreToolUse Bash hook in settings.json ). But the PI agent plane ( agent-runner.js / durable-runner.js ) is a separate Node runtime that does not read ~/.claude/settings.json , so E/B were only soft advisories there. 
 Fix — Hard enforcement at the safe convergence point 
 Two enforcement surfaces added to the PI plane: 
 
 
 mc.js done/ready gate — ~/system/tools/mc.js (~line 2192-2214). Calls lesson-e-b-validator.js check(taskId, task, outcomeMsg, forceFlag) . For deploy/auth/oauth/integration/secret-rotation tasks lacking live-outcome (B) and cred-pair (E) evidence, the gate pushes to blocks[] when enforcement.json.lesson_e_b == "block" . Fail-open: any validator require/internal error is non-blocking. Scoped: only risk categories. --force bypass writes an audit row to /tmp/mc-forced-completions.log (and now routes to CEO approval queue under Reality-Anchor P1.1). 
 
 
 Dispatch brief injection — ~/system/tools/agent-runner.js injects B+E mandatory clauses into every agent contract/brief, so every Ollama PI agent receives them. 
 
 
 Config 
 
 ~/.claude/hooks/config/enforcement.json → lesson_e_b: "block" (flip from warn ). 
 Revert is one line ( block → warn ) if a false-positive ever blocks a legitimate task.
