2.4.0

Release notes for 2.4.0.

Released: 2026-07-03

An internal test-strategy sweep — E2E/CI hardening, wait-pattern guards, shared-fixture consolidation, and test retargeting. No user-facing or generated-scaffold behavior changes.

Features

• Zero-tolerance wait-debt guard for E2E specs (with wait-ok markers), wired into b4push alongside per-step timing (2394139a, c5ed932c)

• Shared E2E fixture now auto-asserts console errors on teardown (dfb4dfea)

• makeDistReader(fixture) helper generalized from the smoke dist helper for L3 dist-read tests (608bc289)

• Real claude-resources template-drift parity guard (91136223)

• Exam CI hardening: trace-on-first-retry with retry-report/artifact wiring, file-exam-issue.sh --green mode, and a pass-on-retry annotation consumer (2b3b3e37, 03589668, 197f3eea)

Bug Fixes

• create-zudo-doc: sync the claude-resources template with package source (615b4e0b)

• Guard a null baseline route-list in parity-diff diff() (25de9d73)

• Recursive E2E spec-naming guard + fixture/config parity check (c64d787a)

• Retry-flake dedup: gh pagination limit and in-run duplicates (a84ca256)

• Search refetch guard: replace the absence-window expect.poll with a debounce-spanning wait (7d96cffd)

• Strengthen the version-banner dist-read visibility assertion (756b072d)

Other Changes

• Migrated E2E specs (sidebar, versioning, header-dropdown, doc-history, design-token-panel, HTML-preview) to the shared console-error fixture; demoted static-markup assertions (versioning, frontmatter-preview, TOC) to L3 dist reads

• Added coverage: markdown-feature goldens, PresetGenerator hydration, llms.txt static emission, doc-route-paths/nav-data-prep L1 suites, and deterministic sidebar-resizer width-restore

• Refactors: extract filterTree/active-slug helpers and a shared normalizeHtml/sha256 module, dedupe extractTrackingIssueUrl, and retarget mirror tests at real implementations

• Docs: reconcile TESTING.md / CLAUDE.md / b4push step counts, document the wait-ok marker convention, and refresh stale test-flow notes
