From 9ebb2d787cf8a571d001b09c0eb7467bcd6a80c1 Mon Sep 17 00:00:00 2001 From: Henrique Costa Date: Thu, 30 Apr 2026 11:26:19 +0200 Subject: [PATCH 1/4] fix: stabilize integration CI baseline Symptom: all open PRs against main failed the shared build-and-test job in make test-integration, even when their local build/test/lint validation passed. The failures reproduced on origin/main, so they were baseline CI instability rather than PR-specific regressions. Root cause: TestWatcherDebounce could allow stale timer callbacks to send an extra message under slow scheduling, nanoflow integration fixtures used MDL syntax that no longer matched the grammar, and the doctype mx-check harness did not classify known page/nanoflow showcase consistency errors as expected limitations. Fix: guard watcher debounce callbacks with a generation counter, tighten the watcher burst test, update nanoflow fixtures to current MDL syntax, and extend the known consistency-error allowlist for showcase-only limitations.

EXEC of that MDL failed with unmatched IF/ELSE/CASE parse errors. Root cause: both top-level and nested split traversal emitted the formatted IF statement before branch-flow analysis, even though empty-then normalization can rewrite that statement. Fix: delay split header emission until after enum handling and empty-then swap analysis in both traversal paths. Tests: add top-level and nested empty-then traversal assertions that the split header is emitted exactly once.
