grind
- drive lexer_throughput from 193.42 to 212.762 via the ledger micro-opt + evolution ratchet. A cycle is KEPT only when
compiler_repo/scripts/bench_probes/measure.sh lexerreads BETTER AND./test-all.shintroduces NO new failures (failing-count <= the baseline floor of 1803); a perf win that adds even one failure over the floor is REVERTED with verdict WORSE + teeth. A CRASHED/ERR suite is a harness break, not a regression — fix the harness, do not count it as a grind regression.
NO ESCAPE HATCHES FROM THE GRIND — no change is too big or too small for it. A tiny tweak is an inline ledger cycle; a LARGE lever (new code surface, whole module, cross-cutting change) is a NEW SECTION added to THIS plan via /create-plan --inline, which earns it proper rigor (its own intel package, /review-section gate, success criteria) WITHOUT leaving the grind. Both are the grind. The new section inherits the SAME plan-scoped ledger (dead-ends + KEPT wins + generalizations); a forked plan starts with an EMPTY ledger. So NEVER spin a lever off to a separate plan (/create-plan without --inline) or a bug (/add-bug), and NEVER apply the served verify-first (2b) spin off into its own plan directive to this grind section — extending the grind with a new direction IS continuing the grind.
