node-v24-compatibility-meta.json held two values derived from the public
compatibility artifact: a content hash for the data URL and its row count.
Every compatibility change rewrote the hash line, so concurrent changes
conflicted on it. next.config.mjs now computes both from the committed
artifact and passes them to the page through Next's build-time env, with
the same values. The generator no longer writes the file, and its local
check compares the public artifact itself.
docs/content/docs/limitations.mdx now holds the frontmatter, the
headings, the anchor spans and one <include> line per partial. The text
moves unchanged to docs/content/limitations/: one file per labeled
bullet (<section>/<label>.mdx) and one per section's other text
(<section>.mdx). Edits to different bullets no longer touch adjacent
lines of one file.
remarkDocsConventions splices the included partials into the page and
joins the lists that consecutive bullet partials contribute, so the page,
its Markdown twin and the search index render as before. The route tests
read the page with its partials inlined. A page that includes partials
takes its last-modified date, used by the sitemap, from the newest commit
to the page or any of its partials.
docs/scripts/limitations-partials.mjs joins the partials back into one
file, splits a single-file page, and merges a branch's edits to the
single-file page into the partials.
The new docs page (/docs/threads) explains @scriptc/threads: a runnable
example that publishes a million-order ledger and sends it to four
workers, verified under Node.js 24 and as a scriptc executable; what
publish accepts and refuses, and that a refused publish leaves the graph
unchanged; the frozen-object TypeErrors of the write guard; a comparison
with Node's structured clone (constant-time sends, preserved classes and
identity, immortal objects) and the three rules that make a program
behave the same under both; the automatic sharing of deeply frozen
untyped data; and the cost model. The limitations page gains a Published
graphs section (immortality, class and identity differences, write-check
evaluation order, private fields) and links the new page from the
worker-threads section.
This is the first page added since the migration, so the route-test
fixture now accepts pages without a legacy URL, and the agent guide's
checklist for new pages names the fixture.
