Three new scripts:
- scripts/garry-output-comparison.ts — enumerates Garry-authored commits
in 2013 + 2026 on public repos, extracts ADDED lines from git diff,
classifies as logical SLOC via scc --stdin (regex fallback if scc
missing). Writes docs/throughput-2013-vs-2026.json with per-language
breakdown + explicit caveats (public repos only, commit-style drift,
private-work exclusion).
- scripts/update-readme-throughput.ts — reads the JSON if present,
replaces the README's <!-- GSTACK-THROUGHPUT-PLACEHOLDER --> anchor
with the computed multiple (preserving the anchor for future runs).
If JSON missing, writes GSTACK-THROUGHPUT-PENDING marker that CI
rejects — forcing the build to run before commit.
- scripts/setup-scc.sh — standalone OS-detecting installer for scc.
Not a package.json dependency (95% of users never run throughput).
Brew on macOS, apt on Linux, GitHub releases link on Windows.
Two-string anchor pattern (PLACEHOLDER vs PENDING) prevents the
pipeline from destroying its own update path.
