The parser now requires a newline or ';' between statements (block() in selfhost/parse.ludic); two statements may no longer sit adjacent with only spaces. Also fixed if-without-else swallowing its trailing separator. Migration: tools/ludic-tools/migrate_separators.c inserts ';' at statement boundaries corpus-wide (examples, runtime, 25 self-host fragments, ~1100 boundaries). Verified semantically identical — the migrated compiler compiles itself to IR byte-identical to the pre-migration seed, and every golden game renders identically. Reseeded to the strict compiler; C-free fixpoint holds; test.sh 14/14. Docs: Rule B documented in LANGUAGE.md; BOOTSTRAP.md R1 + stale fences updated; check-docs green across all docs. Fixed a multi-line string literal in emit_expr.ludic (byte-identical \n escape) that the C toolchain lexer mis-lexes. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
