v0.1.0-next.39

Released: 2026-06-12

Headlined by npm-dist "use client" island scanning (#999 / PR #1001): islands shipped inside regular npm packages under node_modules are now registered and hydrated, so package-provided layout islands work without scaffold-side shims. Plus link-resolution fixes for directory-style hrefs, island-registry hardening, and a test-reliability epic.

Features

• npm-dist island scanning: the island scanner now registers "use client" modules from regular npm packages under node_modules, keyed through each package's exports map (#999, aa88ae2). Require-only CJS packages without an ESM export are treated as inert rather than mis-registered (6c1b47e).

• zfb build warns on island marker-name collisions and hints when a marker likely comes from an npm-package island (#999, b52fe32).

Bug Fixes

• Non-component exports are dropped from the island registry, and generated mount guards harden to a component-shape check (#998).

• React per-island unmount is gated on __zfb_ok like the Preact arm, preventing unmount races on partially-hydrated pages (#1002).

• Directory-relative links (subpage/, ./dir/, ../dir/, dotted directory hrefs) now resolve via extensionless and index-file candidates (#1004).

• Config-loader subprocess spawn retries on transient ETXTBSY errors (#1008).

• Shadow-root paths are canonicalized (macOS only) for byte-deterministic esbuild output across symlinked temp dirs (#1006).

Other Changes

• Test reliability epic (#1013): deterministic ETXTBSY retry/exhaustion tests via an injectable spawn seam (#1014), stale-proof locate_esbuild with loud harness-bug skips, and runtime-root derivation coverage (#1015).

• docs: add "use client" to four dead island components in the docs app; bump @takazudo/zudo-doc to 0.2.1 and retire the copy-public transition fallback (#997).
