[finding] publish-smoke-pack parses the whole pnpm pack --json stdout, so any publishable package that declares prepack reds both smokes at the pack step (armed, unhit) #22705
Description
立卡门类别 ①(可复现的缺陷,具名落点;finding,class a,带 reach:)。Filed by skills seat 1 (session_01RdnZdPZH9ByduzPRWuH9tN) from the os-dev patch-round report on #22658 (comment 6100393030); the seat read the parsing site and the red run.
class: a · reach: the two publish smokes — .github/workflows/os-create-smoke.yml (job "Scaffold outside the monorepo, install, build", step "Scaffold smoke (packed tarballs, outside the repo)") and the release smoke scripts/publish-smoke.sh — both call scripts/publish-smoke-pack.mjs to pack the publishable population. Measured once with a wrong answer: run 38059253305 on PR #22691 head 3372d78b1 (where @objectstack/skills declared prepack) failed at that step with Error: pnpm pack --json returned non-JSON for @objectstack/skills: followed by > @objectstack/skills@17.7.0 prepack …. Reproduced locally with the smoke's step-1 command verbatim (node scripts/publish-smoke-pack.mjs DEST): exit 1, 5,823 bytes on stdout, 0 on stderr, JSON.parse fails with Unexpected token '>'.
Landing: scripts/publish-smoke-pack.mjs packOne (JSON.parse(stdout) of pnpm pack --json --pack-destination DEST). pnpm writes its lifecycle banner (> PKG@VERSION prepack PATH, then the script's command line) and the script's own stdout AHEAD of the JSON document, on stdout, whenever the package declares a prepack script — regardless of what that script prints. So the smoke's verdict depends on a lifecycle hook the package author may legitimately declare, not on the tarball.
Today: no publishable package declares prepack (@objectstack/console and @objectstack/skills use prepublishOnly, which pnpm pack never runs) — the trap is armed and unhit. PR #22691 moved its own check off prepack for exactly this reason (the measurement is in packages/skills/scripts/sync-catalog.mjs's header).
动手的读者: one domain:devx dev (a scripts/ code-quality gate by the anchor rule), one PR on scripts/publish-smoke-pack.mjs: parse the LAST JSON document on stdout (the banner precedes it) or measure which pnpm flag keeps the banner off stdout (--loglevel silent / --ignore-scripts — --ignore-scripts changes what is packed and is ⛔ unless measured equal), and pin it with a self-test fixture whose fake pnpm prints a banner line and then the JSON. ⛔ No change to what the smokes judge; ⛔ no exclusion of any package from the publishable population.
查重: search_issues "publish-smoke-pack pnpm pack --json non-JSON prepack lifecycle banner scaffold smoke pack step" over objectstack-ai/objectstack → 7 hits (open + closed), none this defect; the nearest is #11253 (closed; the pin table derived from the publishable set, the same script, a different defect). Dedupe words: publish-smoke-pack prepack non-JSON · pnpm pack --json lifecycle banner · create-scaffold-smoke pack step.
Priority reading (the seat's, for triage): p3 — no current victim; the next package that declares prepack finds it at its first PR, in CI, loudly.
