# LinkedIn Studio Plugin — Structure Validator
# Validates the REAL v3.1 layout: registration counts (derived dynamically),
# frontmatter shape, hook drift, and plugin.json fields. Counts are asserted
# against the declared contract below, which is kept in sync with the
# CLAUDE.md "## Agents (N)" / "## Commands (N)" headers (cross-checked here)
# and the STATE.md "Telling" block. Adding or removing an agent, command,
# reference, or skill breaks the count-equality and fails the lint — this is
# the registration guard that gates the remediation plan's later steps.
#
# The stat-consistency grep (one magnitude per algorithm effect across the
# tree) is added in remediation Step 3, after reconciliation makes it pass.
# The version-consistency grep is added in Step 21.
#
# Usage: bash scripts/test-runner.sh
# bash 3.2-safe: plain arrays only, no `declare -A`, no `mapfile`/`readarray`.
