Wojciech Różowski 2ce55ba460 fix: catch exceptions in cbv rewrite simprocs to handle projections (#12562) ... This PR fixes #12554 where the `cbv` tactic throws "unexpected kernel projection term during structural definitional equality" when a rewrite theorem's pattern contains a lambda and the expression being matched has a `.proj` (kernel projection) at the corresponding position. The `Sym` pattern matching infrastructure (`isDefEqMain` in `Pattern.lean`) does not handle `.proj` expressions and can throw an exception. Rather than presenting it as an error in `cbv`, we fail quietly and let the `cbv` tactic try other fallback paths. --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>		2026-02-19 11:10:30 +00:00
