Two catalog changes in genie/external.ts, both prerequisites for the StyleX migration. They are small in source and large in fallout, so the evidence is below rather than in a follow-up.

Two of the brief's premises turned out to be wrong. Both corrections are in here with measurements, because a corrected record is worth more than a green one.

1. Storybook 10.4.6 → 10.5.10

The visual gate needs light and dark covered as separate Vitest projects. That is storybookTest({ initialGlobals }).

Verified by diffing the shipped plugin option types rather than trusting release notes:

UserOptions.initialGlobals
@storybook/addon-vitest@10.4.6 dist/vitest-plugin/index.d.ts absent
@storybook/addon-vitest@10.5.10 dist/vitest-plugin/index.d.ts present, documented as "define one Vitest project per theme"

Added in 10.5.0 via #35226. Without the bump the gate cannot express the requirement at all.

10.5.10 is current stable for the whole cohort (next is 10.6.0-beta.1; not taken).

Breaking changes between 10.4 and 10.5

Upstream MIGRATION.md has exactly one entry for From version 10.4.0 to 10.5.0: ExternalDocs and ExternalDocsContainer are deprecated. grep finds no use of either in this repo. Nothing to absorb.

Why the whole cohort moves at once

@storybook/addon-vitest@10.5.10 peers storybook@^10.5.10. Pinning the addon without the cohort would fail strictPeerDependencies, so this is not a matter of taste.

@storybook/addon-a11y is on the list because parameters.a11y.test is inert unless the addon is registered, and it defaults to warn-only. Pinning the vitest addon alone would have produced a gate that silently passes accessibility regressions.

Build evidence — one DOM package and one TUI package

The two go through different factories (createDomStorybookConfig / createTuiStorybookConfig), so one build does not cover the other.

package factory storybook:build resolved stories in index.json
@overeng/effect-schema-form-aria DOM (stylex: true) exit 0 10.5.10 39
@overeng/tui-stories TUI exit 0 10.5.10 11

Zero 10.4.6 references remain in pnpm-lock.yaml or any generated file. (An orphaned storybook@10.4.6 directory lingers in node_modules/.pnpm; zero live symlinks resolve into it — pnpm just has not pruned it.)

Durable constraint introduced by this PR

@vitest/browser, @vitest/browser-playwright and playwright are now welded to the vitest pin. @vitest/browser@4.1.9 peers vitest at exactly 4.1.9 — a literal version, not a range — and @vitest/browser-playwright@4.1.9 peers vitest 4.1.9 plus a non-optional playwright.

A future vitest bump is therefore a four-package move, not a one-line change. Whoever hits that next: this is the PR that introduced the coupling. It is also recorded in the catalog comment.

The versions matter, not just the names: @vitest/browser@4.1.9 ships pixelmatch defaults of threshold: 0.1 and includeAA: false (read from dist/index.js), which is the silent-pass trap the gate exists to close.

playwright does not download browsers at install, on three independent grounds:

  1. The published playwright@1.61.0 tarball's package.json has scripts: null — no hook exists. Same for playwright-core@1.61.0.
  2. ignoreScripts: true is set fleet-wide in the generated pnpm-workspace.yaml.
  3. It is already in pnpm-lock.yaml today, pulled transitively by the existing @playwright/test@1.61.0 pin. Naming it changes no resolution.

Browsers keep coming from the Nix closure. No nativeDependencyPolicy entry needed.

Reported, not fixed: the deprecated @vitest/browser/context import

The brief expected this to "emit a deprecation warning but work via fallback". The second half is right; the first is not, and the difference matters.

@storybook/addon-vitest@10.5.10 dist/vitest-plugin/test-utils.js:54 imports the legacy @vitest/browser/context specifier. But @vitest/browser@4.1.9 dist/index.js:855 handles it like this:

if (id === DEPRECATED_ID_CONTEXT) {
  if (importer && !importer.includes("/node_modules/")) {
    globalServer.vitest.logger.deprecate(`... Please, use "vitest/browser" instead.`)
  }
  return VIRTUAL_ID_CONTEXT
}

The warning is suppressed for importers inside node_modules, which the addon always is. So we get no warning at all — it resolves silently to the same virtual module. Upstream even comments the constant with "for libraries that use an older import but are not type checked".

Practical consequence: this is not noise to live with, it is a silent Vitest 5 hazard. The message says the import "will stop working in the next major version", and nothing in our output will remind us. Not fixed here — it is upstream's import, in a dependency, and the addon's Vitest-4 setup file already uses the correct vitest/browser specifier, so the blast radius is one call site.

2. Tailwind → StyleX converter

Pinned as an opt-in dev tool: catalog entry only, no package declares it. A target that wants the first pass picks it up deliberately. This is the mechanism that keeps it away from shared component packages.

Correction: it is published, and a git-rev pin would not have worked

The brief said to pin an unpublished fork at a git rev. Both halves need correcting.

It is published. tw-to-stylex@0.1.0-alpha.1 on npm, published 2026-02-20 by mellyeliu — the same Meta StyleX maintainer — with gitHead: a150f9e514762c9bab92385e9c0370abda5bc9e6. That is the exact fork revision the brief asked me to pin. We get the intended code through an integrity-pinned npm version instead.

A git-rev pin would have been broken, not merely policy-blocked. This is the part worth keeping, because it is the reason not to re-attempt the original approach:

  • The fork's .gitignore ends with lib — the build output is gitignored, so it is in no git ref.
  • package.json has prebuild/build but no prepare, which is the only script pnpm runs for a git dependency.

Measured, twice:

$ pnpm add "tw-to-stylex@github:mellyeliu/tw-to-stylex#a150f9e…"      # ignoreScripts: true
[WARN] The git-hosted package … has to be built but the build scripts were ignored.
[WARN] Failed to create bin at …/node_modules/.bin/tw-to-stylex. ENOENT: … 'lib/tw-to-stylex.js'
Done in 4s                                                            # exits 0!

$ node -e "import('tw-to-stylex')"
FAIL: ERR_MODULE_NOT_FOUND Cannot find module '…/tw-to-stylex/lib/index.js'

Repeated with lifecycle scripts fully enabled: identical result, no lib/. There is no prepare for pnpm to run, so relaxing ignoreScripts fixes nothing. This was never a dependency-policy question. Install succeeds, and every invocation dies.

So the answer to "is pinning an unpublished fork acceptable under repo policy" is that the question dissolved: the fork is published, and the git-rev route was not viable under any policy.

The undeclared Babel deps are subtler than "two missing peers"

@babel/plugin-syntax-typescript is declared as a dependency of tw-to-stylex. It still fails, because Babel resolves plugin names relative to the calling package, not the plugin's own tree. Reproduced from a clean install:

Error: Cannot find package '@babel/plugin-syntax-jsx' imported from /tmp/twbare/babel-virtual-resolve-base.js
# after adding it:
Error: Cannot find package '@babel/plugin-syntax-typescript' imported from /tmp/twbare/babel-virtual-resolve-base.js

npm's hoisting masks this half the time; pnpm's strict layout will not. All three (@babel/core, @babel/plugin-syntax-jsx, @babel/plugin-syntax-typescript) are pinned at 7.29.7. Babel 7, not 8: @babel/plugin-syntax-typescript@7 peers @babel/core@^7, and Babel 8 trips strictPeerDependencies (pnpm peers check confirms).

Clean install under this repo's actual policy (ignoreScripts: true, strictPeerDependencies: true) — no warnings.

Converter evidence, with logging on

logUnsupported defaults to false in every entry point. Same input, both ways:

Default (off) — three classes vanish, zero diagnostics:

----- OUTPUT -----
const _styles = _stylex.create({ … })

{ logUnsupported: true }:

[TW→StyleX] Unsupported Tailwind pattern: group-*
  Class: group-hover:text-blue-600
  Reason: requires parent element state
[TW→StyleX] Unsupported Tailwind pattern: peer-*
  Class: peer-checked:block
[TW→StyleX] Unsupported Tailwind pattern: [&...] arbitrary selectors
  Class: [&>svg]:size-4

It does emit the pattern the spec specifies:

color: { default: "#111827", [_stylex.when.ancestor(":hover")]: "#2563eb" }
// …
<div {..._stylex.props(_stylex.defaultMarker(), _styles.$1)}>

Three traps found while wiring it, all recorded in the catalog comment

  1. The CLI can never log. tailwindToStylex() passes the plugin bare, so pluginOptions is undefined and logUnsupported is permanently false. The tw-to-stylex binary uses that function. Only tw-to-stylex/sync (or the default export used as a Babel plugin with options) accepts the flag. Use of the CLI is ruled out in the comment.

  2. React Aria data-[*] state is dropped with logging ON. This contradicts the brief, which listed data-[*] among what the flag surfaces. It does not — UNSUPPORTED_CLASS_PATTERNS only matches group-, peer-, *: and [&. Measured:

    input:  bg-white data-[selected]:bg-blue-500 data-[disabled]:opacity-50 data-[focus-visible]:outline-2
output: { backgroundColor: "#fff" }        # with logUnsupported: true — zero warnings

    Three React Aria states gone, silently, with the safety flag on. This is exactly why the spec forbids pointing it at a shared component package, and the flag does not make that safe.

  3. The warnings over-report. It warns that group-hover: "will be ignored" and then converts it correctly via when.ancestor. Treat the log as a review prompt, not a defect list.

Output also carries raw values (#111827, .5rem) and leaks Tailwind internals (--tw-font-weight), so the hand-pass the spec requires is unavoidable.

Fallout

packageExtensions restated the framework version as a literal 10.4.6 in genie/internal.ts, which would have left a second @storybook/react-vite resolving. It now derives from the catalog so it cannot drift again.

Changing it moved packageExtensionsChecksum, which broke the Nix build before devenv could enter the shell:

[ERR_PNPM_LOCKFILE_CONFIG_MISMATCH] … "packageExtensionsChecksum" … doesn't match the value found in the lockfile

Fixed with pnpm install --no-frozen-lockfile --lockfile-only. Worth knowing for anyone touching packageExtensions: the repo task cannot bootstrap itself out of this.

Regenerating the lockfile then invalidated eight pnpm-deps FODs, cascading one per ~20-minute cycle. Batched instead with a single nix build --keep-going over all eight *-pnpm-deps attrs, then refreshed and re-verified in one pass. All hashes here are values Nix measured.

For anyone rebasing onto this branch: your own dependency changes will invalidate these hashes again. Take the got: value Nix prints for your build. Do not carry a hash forward from this PR — a carried-forward hash is the classic way these go subtly wrong, because it looks plausible and fails somewhere else.

The unplugin duplicate exception was re-checked rather than assumed to be retired by the bump: @storybook/csf-plugin@10.5.10 still declares unplugin ^2.3.5, so it is still required. Its reason now describes the constraint rather than naming a consumer package, since the consumer is moving in a sibling PR — and the old text's claim of an "exact pin" was wrong (^2.3.5 merely resolves to 2.3.11).

Tooling gap

evergreen fod refresh --name <pkg> writes the correct hash for the seven CLI-shaped attrs, but its post-write verification always fails here: it evaluates import <build.nix> { inherit pkgs; } while this repo's build.nix files require a src argument, so every refresh warns could not evaluate … called without required argument 'src'. The hash is right; the check is inoperable. I re-verified all eight independently with a batch nix build.

nix/oxc-config-plugin.nix is worse: evergreen fod reconcile/refresh cannot address it at all (could not determine --hash-source for oxc-config-plugin), and evergreen fod cli-packages-values reports 0 known attrs in this repo. That hash had to be written by hand from the measured value — in a tool we are told to reach for before hand-editing.

Verification

  • devenv tasks run check:quick — green (exit 0)
  • storybook:build green for one DOM and one TUI package, both on 10.5.10
  • Converter runs from the published package under this repo's pnpm policy, with unsupported-class logging visible
  • All eight pnpm-deps FODs rebuild clean

Not run: project-wide formatters or the full test suite, per instructions.

pin the StyleX lint plugin and the Tailwind->StyleX converter
2e08497 
Both are catalog-only: nothing declares them yet, so no generated file
or lockfile entry moves. Consumers opt in per package, which is the point
for the converter — it must never reach a shared component package.

@stylexjs/eslint-plugin rides at 0.19.0 rather than its own latest so it
stays in lockstep with the compiler pins; its dependency closure pins
@stylexjs/shared 0.19.0, so a split would be silently incoherent.

The converter is pinned to the published 0.1.0-alpha.1 rather than a git
rev of the maintainer's fork. The fork is where the useful work is, but
its build output is gitignored and it declares no `prepare` script, so a
git-rev install resolves to a package with no lib/ at all and every
import dies with ERR_MODULE_NOT_FOUND. That is true even with lifecycle
scripts fully enabled, so it is not a policy question. alpha.1 carries
gitHead a150f9e, the exact fork revision that was wanted, and ships the
built output, so we get the intended code through an integrity-pinned
npm version instead of an unbuildable git reference.

The three @babel/* pins are load-bearing, not incidental. Babel resolves
plugin names relative to the calling package, so the consumer must
declare the syntax plugins even though the converter lists one of them
as its own dependency; without them every invocation fails. Babel 7
because @babel/plugin-syntax-typescript@7 peers @babel/core@^7 and
Babel 8 trips strictPeerDependencies.
@schickling-assistant
require Storybook 10.5 so the visual gate can test one project per theme
6003e7d 
The gate needs light and dark covered as separate Vitest projects. That
is `storybookTest({ initialGlobals })`, added in 10.5.0 (#35226) and
absent from 10.4.6 — verified by diffing the shipped plugin option types,
not by reading release notes: 10.4.6's UserOptions has no such field,
10.5.10's documents it as "define one Vitest project per theme". Without
the bump the gate cannot express the requirement at all.

10.5.10 is current stable across the whole cohort. Checked upstream
MIGRATION.md for 10.4->10.5: one entry, the deprecation of ExternalDocs
and ExternalDocsContainer, which this repo does not use. No breaking
change to absorb.

@storybook/addon-vitest peers `storybook@^10.5.10`, so the cohort has to
move together rather than one package at a time. addon-a11y is here
because parameters.a11y.test is inert unless the addon is registered, and
it defaults to warn-only.

genie/internal.ts had the framework version restated as a literal in
packageExtensions, which would have left a second @storybook/react-vite
resolving after this bump. It now derives from the catalog so it cannot
drift again. The unplugin duplicate exception was re-checked rather than
assumed: @storybook/csf-plugin@10.5.10 still declares unplugin ^2.3.5, so
the exception is still required. Its reason now names the constraint
instead of a consumer package, because the consumer is moving.

The pnpm-lock regeneration invalidated eight pnpm-deps FODs; those hashes
are the measured values, refreshed in one batch.

Proof: storybook:build green for one DOM package
(effect-schema-form-aria, 39 stories) and one TUI package (tui-stories,
11 stories), both resolving 10.5.10, since the two share a factory but
not a code path. check:quick green.

Merge origin/main into the StyleX catalog-pins stack base
219a1c3 
Resolves eight conflicts, all in Nix derivation files, all taking main's side.

Seven are fixed-output hash collisions on mkSharedHash: both branches changed
dependency topology, so both recorded a different pnpm closure hash and NEITHER
is correct for the merged tree. Taking a side here is not the resolution -- it
just picks a starting point. The hashes are refreshed as a batch in the next
commit, which is Evergreen's layer ordering: authority and semantics first,
derived artifacts after, never one hash per cycle.

The eighth, nix/oxc-config-plugin.nix, is structural rather than a hash
collision and main's side is strictly better: main derives pnpmDepsHash from a
shared depsBuilds entry where this branch still carried a literal sha256, so
taking main removes a hand-maintained hash outright.

build(nix): refresh seven pnpm closure hashes for the merged tree

The merge of main brought a third dependency state, so neither side's hash was
correct: measured, genie's merged closure hashes to vtu2jnhz... where this
branch carried BdWDmLT9... and main carried H5i7Vtl.... Refreshed as one batch
through evergreen rather than one hash per cycle.

Two independent corroborations rather than one:

- genie's written value exactly matches what a plain 'nix build' printed as
  'got:' before the refresh ran, so the tool measured rather than merely wrote.
- All seven build to real store paths. That is a POSITIVE assertion, not an
  absent error: evergreen skipped its own post-write verification on
  npm-release and tui-stories because its verifier imports build.nix with only
  'pkgs' while these files require 'src', so a silent pass there would have been
  indistinguishable from an unverified write.

Superseded by #1191, which collapses this stack onto main as one tree.

Closing rather than merging: propagating main through eight stacked branches meant re-reconciling the lockfile, the fixed-output hashes and the Buck projection once per branch. Branch 2 alone produced 11 conflicts, a semantically broken auto-merged lockfile, a BUCK admission rename and a circular tooling block. On one tree each of those happens once.

This PR's content is in #1191, verified with git merge-base --is-ancestor over all eight heads — #1184 was found missing that way and merged in, because a gh stack base does not make a branch contain that base.

This body stays as the record of the per-change evidence, which #1191 summarises but does not reproduce in full.
