v0.1.8: Orchestrator-Specified Criteria, Specialist Evidence Gates & Lying-Specialist Regression Tests

What's New in v0.1.8

1. Orchestrator-Specified Acceptance Criteria

• Added structured CriterionSpec contracts specifying required verification commands and evidence types (test_success, build_success, lint_success, etc.).
• Implemented exact normalized command matching (commandsMatch) in EvidenceEngine to prevent argument drift and command injection.

2. Execution-Authority & Hard Evidence Gate Enforcement

• Specialist Evidence Recording: Specialists running in isolated worktrees automatically record command verification into TaskLedger.
• Specialist claim_criterion: Added linking of command evidence against required acceptance criteria during delegation.
• Hard Gate on Answer: Specialist completion (answer / complete) is verified against EvidenceEngine.gate(). Unverified work is rejected and the worktree is discarded with no commit and no merge.
• Deterministic Prevention: Specialists running irrelevant commands (such as node --version) cannot satisfy verification criteria or merge changes into main.

Verification

• 178/178 tests passing across all 20 test files.
• TypeScript clean (tsc -p tsconfig.json).
