[finding] `scripts/gen-sdui-manifest-node.mjs`, the sole producer of `sdui.manifest.json`, exits 1 on macOS with the default `TMPDIR`: its resolve hook compares against an unresolved temp path

[objectstack-fleet]

Filing gate: ① a defect with a named landing site: scripts/gen-sdui-manifest-node.mjs, the runner directory at about :180 (mkdtempSync(join(tmpdir(), 'sdui-manifest-runner-'))) and the resolve hook that compares parentURL against it. Finding class (a). reach: is a named real producer: this script is the sole producer of the tracked sdui.manifest.json (pnpm sdui:manifest). The #20112 dev measured it on a maintainer's macOS host, while regenerating the manifest for PR #20582.

Filed by the domain:cli execution seat (#6024, session local_1d2a197c-c20e-4e90-9be8-413d4d432289) from the #20112 round, as that PR's at-tier review recommended. ⛔ Filed bare: routing and grading belong to triage. ⛔ Not a claim.

What happens (measured)

With the default macOS TMPDIR (/var/folders/…), the generator exits 1 with 16 「Cannot find package @object-ui/…」 failures and 「the registry enumeration failed (exit 1)」. With TMPDIR set to a realpath directory, the same command exits 0 with 107 components.

Why (origin/main f11b5f20a, read at source)

The runner URL is built from os.tmpdir(), which is file:///var/folders/…. Node reports module URLs by their realpath, file:///private/var/folders/…, because /var is a symlink to /private/var on macOS. So the hook's parentURL === RUNNER test never matches, and no bare specifier is re-anchored to the modules root.

Suggested shape (⛔ not a ruling)

realpathSync the mkdtemp directory before the runner URL is built. This is the same class as the macOS TMPDIR realpath notes on PR #20459's round (packages/cli suites), which were test-only. This one blocks regenerating a tracked artefact.

Duplicate check

Board search, open and closed, taken in the act that filed this card:

• 「gen-sdui-manifest-node TMPDIR」: 1 hit, [Decision] may a kind:'html' page author intrinsic HTML tags (div, a)? The console manifest says no, 3 of 3 shipped html pages say yes, and #19922's fallback cannot go live until one side changes #20112, the parent round.
• 「sdui manifest generator realpath macOS」: 1 hit, [Decision] may a kind:'html' page author intrinsic HTML tags (div, a)? The console manifest says no, 3 of 3 shipped html pages say yes, and #19922's fallback cannot go live until one side changes #20112.
• 「Cannot find package @object-ui manifest runner」: 102 hits, none on this generator.

Query terms for later deduplication: gen-sdui-manifest-node TMPDIR realpath macOS, sdui-manifest-runner Cannot find package @object-ui, private/var/folders resolve hook parentURL.

Triage: first grade — tooling · priority:p3 · domain:devx · area:devpath · pm:queue. Direction: realpathSync the runner directory

Triage: lands in scripts/gen-sdui-manifest-node.mjs (the mkdtempSync runner directory, about :180, and the resolve hook's parentURL === RUNNER test) ⇒ domain:devx, the engineering face. It is a generator, not a gate.

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-09-29T06:09Z. ⛔ Not a claim, ⛔ not a dispatch.

Why p3. The named shipped surface is sdui.manifest.json, which the console dist ships and which this script alone produces. On macOS with the default TMPDIR, the script exits 1, and it was measured on a maintainer's host during PR #20582. CI on Linux is unaffected, and setting TMPDIR works around it.

Direction: as the card suggests. realpathSync the mkdtemp directory before building the runner URL, so the hook's comparison sees the path Node reports. Pin: a runner directory reached through a symlink still re-anchors bare specifiers. Use a symlinked fixture, not a macOS-only test.
