FORGE Route Gate MC101641

MC #101641 implements forge-route-gate.sh, a Claude Code PreToolUse:Task hook that blocks verifier-class Opus dispatch when FORGE local inference is healthy.

Hook file

~/.claude/hooks/forge-route-gate.sh

Settings wiring

~/.claude/settings.json includes bash ~/.claude/hooks/forge-route-gate.sh in the Task hook path.

Verifier-class detection

The hook treats the following subagent classes as verifier/reviewer/comparator class:

verifier
reviewer
comparator
baseline
evidence-verifier
redzo-reviewer
pi-orch-mini-verifier

Required behavior

Non-verifier Task calls pass through.
Verifier-class Task calls are blocked with exit 2 when FORGE is healthy.
If FORGE is unreachable, the hook allows fallback to Opus with a warning.
FORGE_GATE_BYPASS=1 allows explicit override and writes bypass audit logs.

Evidence

Durable remediation evidence for review is stored under /tmp/101641-evidence/, including fresh syntax/settings checks, live FORGE-healthy block smoke, simulated FORGE-down fallback smoke, bypass smoke, and direct probe output.

Dependency status

MC #101652 is now ready_for_review with a PARTIAL/BLOCKED validation finding. It does not prove the full restructure complete, but the dependency is no longer open/unstarted.
