No-DB cli.ts route (brings its own PGLite), --out as the canonical CI
artifact, explicit grace-tick process.exit(verdict) (PGLite exitCode-hijack
+ Bun stdout-discard guards), anti-vacuous-pass + seed-failure exit-2 paths,
_meta.metric_glossary block, --update-baseline canonical writer,
--compare with main-baseline governance. eval run-all's brainbench stub is
now wired in-process: one record per sweep, schema_version 3, mode 'n/a'.
Subprocess e2e pins literal exit codes 0/1/2 end to end.
