v0.1.7: export drift clearance — release checklist 7.7 three-leg desktop feed dispatch + verify-feed.ts fail-loud validation (main-repo commit 867502fec), implement SKILL Producer test preflight core-neutral block (main-repo commit 4a149fccf); clears both pending content-drift findings

+**Producer test preflight** (before writing any test):

+1. **No absolute-path targets outside the test's own fixture/instance dir** — target fixtures or instance-relative paths instead. Where behavior is
+   platform-dependent (path resolution differs Windows/Linux), assert the
+   platform-specific expectation explicitly; a platform mismatch must fail,

+2. **Polling/wait-for loops must be bounded AND non-vacuous** — bound the

+   counter asserted after the loop), so a timeout-cut never yields a false
