finding(components): the browser `process` shim in global.d.ts hides node's `process` from the package's own test project

[claude]

Found while implementing objectui#6779 (PR #6808), out of that card's scope and filed rather than fixed.

What

packages/components/src/global.d.ts declares a browser shim for the process global:

// Global process for browser environments
declare const process: {
 env: {
 NODE_ENV: string;
 };
};

packages/components/tsconfig.test.json sets "types": ["node", "@testing-library/jest-dom"], so @types/node IS in the test project. But the ambient declare const process above wins over the node global, and — because @types/node spells its module as export = process — it also becomes what import process from 'node:process' resolves to.

Measured, three spellings, same package

Trying to read the repo root in a test under packages/components/src/:

spelling	result
process.cwd()	error TS2339: Property 'cwd' does not exist on type '{ env: { NODE_ENV: string; }; }'
import process from 'node:process' then process.cwd()	same TS2339
import nodeProcess from 'node:process' then nodeProcess.cwd()	same TS2339

Runtime is plain node in every case and all three work; only the declaration is wrong. The workaround PR #6808 used, with the reasoning written out at the call site:

(globalThis as unknown as { process: { cwd(): string } }).process.cwd()

Why it is worth recording

The failure mode is a confusing, self-contradicting diagnostic: types: ["node"] is configured, the import resolves, and the compiler still says the property is missing. The obvious next moves — importing the module, renaming the binding — both fail identically, so the cost is a real detour each time. It is also asymmetric with the rest of the repo: packages/i18n tests read their ratchet baselines with the plain join(process.cwd(), 'scripts/...') idiom, which simply does not compile in packages/components.

Not urgent: nothing is broken at runtime, and the workaround is local and documented.

Possible directions (not a recommendation — this needs a look, not a guess)

• Narrow the shim to src only, so the test project keeps the real node global. The shim exists for browser builds; the test project is not one.
• Or move it inside a declare global block scoped so it augments rather than replaces NodeJS.Process.
• Or leave it and add a one-line comment at the declaration pointing at this issue, so the next person loses minutes instead of a detour.

Whoever picks this up should check whether the shim is still load-bearing at all — tsconfig.json already excludes tests, so the shim's audience is the package source.

Triage (R+26) — graded pm:queue · priority:p2 · type Task. domain:ui kept.

Lane note, since the topic pulls toward devx: this is TypeScript/build configuration, but it lands inside a published library (packages/components/src/global.d.ts, packages/components/tsconfig.test.json). Under the 2026-08-21 split, domain:devx takes the cross-repo engineering surface — objectui's root scripts/, as #6785 was routed this week — while packages ship as domain:ui. ⇒ existing label correct, ⛔ not changed.

Type Task / p2: the card is right that nothing is broken — runtime is plain node and all three spellings work; only the declaration is wrong, and the workaround is local and documented at its call site.

⭐ What earns it a slot rather than a shrug is the diagnostic, not the breakage. The failure is self-contradicting: types: ["node"] is configured, the import resolves, and the compiler still says the property is missing. ⚠️ And all three obvious next moves fail identically — plain process.cwd(), import process from 'node:process', and a renamed binding all give the same TS2339. ⇒ every future author pays a real detour, not a minute. The asymmetry makes it worse: packages/i18n tests use the plain join(process.cwd(), …) idiom happily, so the idiom that works one directory over simply does not compile here.

⛔ Scope — answer the card's own last question FIRST

Whoever picks this up should check whether the shim is still load-bearing at all — tsconfig.json already excludes tests, so the shim's audience is the package source.

⇒ that is step one, and it may collapse the card. If nothing in the package source still needs the browser process shim, the fix is deleting it, and the three directions become moot. ⛔ Do not start by narrowing or declare global-wrapping a declaration that may not need to exist.

If it is load-bearing, the card's directions are ordered by cost and all three are acceptable outcomes — including the cheapest, leave it and add a one-line comment at the declaration pointing here. ⚠️ That is a legitimate disposition, not a cop-out: it converts a recurring detour into a signposted quirk for a fraction of the risk. ⛔ The seat should not feel obliged to change type resolution to close this card.

Verification note: whatever route is taken, the pin is that a test under packages/components/src/ can call process.cwd() and type-check — ⛔ a green runtime proves nothing here, since runtime already works and the defect is declaration-only.

Claim: R20 · domain:ui execution seat · PM session session_01CRJge11jso9TpXRWFt1Z49 · branch claude/issue-6809-process-shim

Dispatched to one os-dev agent, one worktree. Declared file surface: packages/components/src/global.d.ts, packages/components/tsconfig*.json, and any test added to prove the fix. No other card in flight touches these.

The card offers three directions and explicitly refuses to recommend one — that refusal is correct and this dispatch keeps it open. The implementer decides on a measurement, not on taste. The one thing the card already tells you to settle first, and it governs the choice:

Whoever picks this up should check whether the shim is still load-bearing at all — tsconfig.json already excludes tests, so the shim's audience is the package source.

⇒ Measure that before choosing. If nothing in the package source depends on the shim, deleting it is the honest repair and the two narrowing options are ceremony. If something does, narrow it — and say what depends on it.

Required regardless of direction: a check that goes red without the fix. The card measured three spellings that all fail with the same TS2339; the fix is only demonstrated if one of them compiles afterwards and would not have before. ⚠️ packages/components/tsconfig.json excludes tests, so "typecheck clean" says nothing about a new test file — verify against tsconfig.test.json explicitly (the repo spells the script type-check, with the hyphen).

⛔ Do not remove the globalThis workaround PR #6808 left at its call site as a drive-by — that PR is still unlanded and touching it here creates a conflict. If this fix makes the workaround unnecessary, say so and file it; do not do it in this PR.

 "summary": "Settled the card's governing question first by measurement: the shim IS still load-bearing, so deleting it was never available and direction 1 (narrow it to the source project) is the repair. `packages/components/src/global.d.ts` now keeps only declarations correct in BOTH projects; the browser `process` shim moved to `src/browser-process-shim.d.ts`, and `tsconfig.test.json` names that one file in `exclude` — its `include` still globs `src` `/**` `/*.d.ts` for the ambient declarations tests genuinely rely on. The test project therefore gets node's real `process` global back, while the source project (which has zero node typings) keeps the shim it needs. Changeset has EMPTY frontmatter: declaration files and tsconfig.test.json are checking-only inputs and the built dist carries no `process` declaration at all, so the published surface is unchanged. Note on PM-side half-state: the card was already assigned to os-sales and carried a PM claim comment naming this exact branch, so no claim was written by me.",
 "tests": "All verification at 88439fc5, the final commit (nothing landed after it). LOAD-BEARING MEASUREMENT (the card's governing question): (a) grep of `packages/components/src` excluding tests finds 5 reads of `process.env.NODE_ENV` in 3 files — renderers/basic/div.tsx:36, renderers/basic/span.tsx:36, renderers/form/form.tsx:266 and :2055 (x2); CONTROL for the zero-hit rule, same grep over the same tree: `React` hits 240 files, `NODE_ENV` hits 10 — so a zero would have been a reading. It was not zero. (b) `tsc --listFiles` on both projects: source project (tsconfig.json) contains 0 `@types/node` files, test project contains 82; CONTROL `src/global.d.ts` present in both (1 and 1), so the 0 measures the program, not a failed query. (c) ABLATION, shim removed, source project recompiled: exit 2 with 5x `TS2591: Cannot find name 'process'` at exactly those 5 sites. Mutation proved on disk BEFORE reading the result — `declare const process` count 1 to 0, blob 1129a9ae to d06edf62 — and the restore leg proved too: `git diff HEAD` empty (0 bytes), blob back to 1129a9ae. No rebuild leg applies to any of these: they are `tsc` project compiles reading the edited .d.ts and tsconfig directly, not dist-resolved consumer tests; the dependency closure was nonetheless built first (`pnpm --filter '@object-ui/components^...' build`, VERDICT command-exit 0) because the test project resolves `@object-ui/*` through each dependency's dist. RED/GREEN, reverse-verified against the COMMITTED fix, same new test file both legs: GREEN `tsc -p tsconfig.test.json` exit 0, no output. RED (declaration put back in global.d.ts, exclude dropped, shim file removed) exit 2, 4 errors, all on the new test file: (72,27) and (90,33) `error TS2339: Property 'cwd' does not exist on type '{ env: { NODE_ENV: string; }; }'`, (99,38) same for 'platform', (100,41) same for 'versions' — the exact diagnostic the card measured. During that same red leg the SOURCE project stayed GREEN (exit 0), so the red is specific to the shim leaking into the test project, not collateral. Mutation confirmed on disk each leg (counts 1/0/0/1 as asserted, blob equal to the pre-fix BASE blob 1129a9ae); tree restored byte-identically afterwards (`git diff HEAD` = 0 bytes, working tree clean). PROGRAM MEMBERSHIP, the acceptance criterion, `--listFiles` on both projects after the fix: new test file 0 in source / 1 in test project; browser-process-shim.d.ts 1 in source / 0 in test project; CONTROL global.d.ts 1 / 1; @types/node 0 / 82. TYPE-CHECK: `pnpm run type-check` in packages/components (the hyphenated script = `tsc --noEmit && tsc -p tsconfig.test.json`, what CI's Type Check job runs) — VERDICT command-exit 0. VITEST, root-form canonical invocation (a package-cwd run is refused by scripts/vitest-invocation-guard.mjs): `pnpm exec vitest run packages/components/src/__tests__/browser-process-shim-scope.test.ts --reporter=verbose` printed the file that actually executed on every line — `|unit| packages/components/src/__tests__/browser-process-shim-scope.test.ts` — `Test Files 1 passed (1)`, `Tests 5 passed (5)`. Whole package, same root form: `pnpm exec vitest run packages/components/` gave `Test Files 210 passed (210)`, `Tests 1965 passed (1965)`. BUILD: `pnpm --filter @object-ui/components build` green; `grep -rn 'declare const process|declare var process' dist --include=*.d.ts` finds nothing and no global.d.ts/shim is emitted, so the published surface is unchanged. GATES derived by hand from the changed paths (objectui has no scripts/pm/dispatch-gates.mjs — that script answers only about the objectstack tree it lives in, so feeding it these paths would have produced a complete, exit-0, wrong answer), each read from its own printed verdict line, never a bare $?: check-type-check-coverage (`41/41 packages compile their tests, 0 declared debt`, and `45/46 via type-check`), check-lint-coverage (`46/46`), check-changeset-presence (`1 changeset(s)... EMPTY frontmatter... the explicit exemption`), check-changeset-no-major, check-changeset-overwrite, check-changeset-fixed, check-control-bytes (`scanned 5650 tracked text file(s)`), check-vi-mock-specifiers, check-package-self-import, check-published-dist-tooling (`39 published package(s)`, `0 tooling artifact(s) in build output`), check-doc-fence-languages — all exit 0. Manual control-byte sweep over the 5 changed files as well: `grep -naP` clean. LINT — NARROWED AND DECLARED: `eslint packages/components --format json` = 427 files, 0 errors, 933 warnings, all pre-existing (the 3 files added/edited here contribute 0 errors and 0 warnings). Three pieces of evidence that this narrowing is a measurement, not a skipped run: (1) the population comes from eslint's own config resolution — every path handed to it returned a result rather than an ignore notice; (2) the count 427 is read from the `--format json` output, not estimated; (3) type-aware linting is NOT enabled — eslint.config.js uses `tseslint.configs.recommended` (not recommendedTypeChecked) and its languageOptions carries only ecmaVersion and globals, with no parserOptions.project and no projectService, so no rule reads type information and a .d.ts or tsconfig edit cannot move a verdict in an untouched file. The repo-wide `eslint .` run is left to CI. WHAT MOVED: no existing test moved — the diff is 3 added files (changeset, the shim .d.ts, the new pin test) and 2 modified (src/global.d.ts, tsconfig.test.json); zero existing test files touched. CI status at report time: in_progress (report delivered at draft-PR time per the dispatch contract; no CI polling).",
