From 1980d961eeea927c2623525b7f8a7f2a3d09f5cb Mon Sep 17 00:00:00 2001 From: Ralf Anton Beier Date: Mon, 18 May 2026 20:35:42 +0200 Subject: [PATCH] =?UTF-8?q?fix(verify-gate):=20keep=20TEST-PROOF-*=20on=20?= =?UTF-8?q?sorry-grep=20=E2=80=94=20lake=20build=20exceeds=20gate=20budget?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PR #227 reverted TEST-PROOF-* steps to `cd proofs && lake build` on the assumption smithy's ELAN_HOME deploy made it possible. It does work — `lake` runs cleanly — but the lake build against Mathlib on a cold elan cache routinely exceeds 30 minutes. PR #229 bumped the gate budget to 60min and the FIRST PR after #229 ALSO hit the new ceiling. The dedicated "Lean proof typecheck (lake build)" CI workflow has `actions/cache@v4` on `proofs/.lake/build`, so its run completes in seconds on warm cache. The rivet verification gate doesn't cache that path, so it pays the full Mathlib cold-compile cost every run. Right structural fix: the verify-gate's purpose is "surface drift between YAML claims and reality". A sorry-free grep on the proof file IS a meaningful drift check: it catches "agent accidentally left a sorry". Full type-checking is the dedicated workflow's job — defense in depth, separation of concerns. Reverts to the sorry-grep + file-exists pattern from before #227. Future work: add lake cache to verify-gate so this restriction lifts.
