-# compile through recoverable source errors
+# execute through recoverable source errors

-Honey produces an executable whenever source errors can be represented safely: structurally valid syntax trees may contain typed invalid nodes carrying source spans and diagnostic identities, and semantic checking or lowering turns demanded invalid code into diagnostic runtime traps. clean compilation returns status `0`, compilation that emits an executable with source diagnostics returns `1`, and unrecoverable infrastructure or backend failure returns `2`. this deliberately favors testing unaffected program paths over conventional fail-fast compilation; parser recovery must preserve valid surrounding syntax, while compact syntax-tree storage remains private behind typed views.
+Honey lowers recoverable source errors into typed, target-independent IR with source spans and diagnostic-bearing trap terminators; the interpreter executes that IR first, and future native backends reuse the same lowering rather than duplicating frontend semantics. invalid code traps only when execution reaches it, allowing unaffected program paths to run; parser recovery preserves surrounding syntax and compact syntax-tree storage remains private behind typed views. clean execution returns status `0`, source diagnostics or runtime traps return `1` even when an unaffected entry point finishes successfully, and usage or unrecoverable infrastructure failure returns `2`.
