pulse/scripts/dev-prepush.sh

#!/usr/bin/env bash
#
# Fast local validation before pushing to main. CI takes 10+ minutes to
# deliver a verdict; this catches the common failure classes in a few:
#
#   1. canonical completion guard (contract/verification coupling, per commit)
#   2. guard/registry snapshot tests when the subsystem registry changed
#   3. mutation registry audits (fail closed on unclassified API routes)
#   4. compilation plus tests for the Go packages the outgoing commits touch
#   5. frontend type-check when frontend-modern changed
#
# Usage: scripts/dev-prepush.sh [base-ref]
#   base-ref defaults to origin/main. Run `git fetch origin` first for an
#   accurate range. Tests here run without -race for speed; CI still runs
#   the full -race suite across all packages.
