From 2c9b3bb31dd0246b35e36bf508095725066aaa74 Mon Sep 17 00:00:00 2001 From: can1357 Date: Wed, 19 Aug 2026 12:48:11 +0200 Subject: [PATCH] fix(pi-ast): skip repo-corpus differential when the corpus is not staged bazel test sandboxes stage only the crate's declared inputs, so the repository sweep found zero sources and tripped its own evidence guard ('corpus sample too small to be evidence: 0'). Skip on a missing or empty corpus; any non-empty scan still enforces the >40-file evidence floor. --- crates/pi-ast/src/block.rs | 14 ++++++++++++++ 1 file changed, 14 insertions(+) diff --git a/crates/pi-ast/src/block.rs b/crates/pi-ast/src/block.rs index 7acb075cf..33fbb05a3 100644 --- a/crates/pi-ast/src/block.rs +++ b/crates/pi-ast/src/block.rs @@ -889,7 +889,21 @@ mod tests { #[test] fn pruned_walk_matches_unpruned_on_repo_corpus_sample() { + // Sandboxed runners (bazel test) stage only this crate's declared inputs, + // so the repository corpus this sweep samples is absent (or a symlink + // farm the walker cannot see through).
