finding(tooling): CI "Type Check · workspace" OOMs in plugin-hono-server (tsc exit 134, no type error) because its tsconfig type-checks spec's dist .d.ts without skipLibCheck, and the heap margin on main is nearly gone #26288

Closed

Description

@objectstack-fleet

Filing class: ① a product defect with a named location and a reproduction. Here the product is the repo's required CI lane.

reach: measured on the public CI entry. The Type Check · workspace job of PR #26244 died with a tsc heap OOM (exit 134, no type error) at heads 2d0dd7dd and c33b95d8. The same lane passed at 6c5c49cc with identical types (run 40370187707 is the red at c33b95d8).

Business reason. Any PR that touches packages/spec pulls plugin-hono-server into the affected set. When the lane OOMs it goes red on a PR with no type error, and the seat must re-run the job or stall the merge queue. Each re-run costs a CI cycle, and the chance of a red grows with every spec declaration added. If nothing is done, the lane will fail on main itself once the margin is gone.

Who acts. The seat that owns tooling and CI, after triage routes it. The fix is one line plus a measurement (below).

Measurement (by the #25779 dev, recorded in os-dev-report 6424852503)

Expected

The lane passes with a real margin. The likely fix is skipLibCheck: true in that tsconfig, or extending the repo's base tsconfig that already sets it, so long as no lib-check-only error class is lost. Confirm that by reading what the other plugins' tsconfigs do.

Dedupe

The query "typecheck heap out of memory plugin-hono-server tsc OOM skipLibCheck" in objectstack issues returned 6 hits, all closed: #17708, #14569 (same class, other lanes: the type-check-debt and debt-ledger tsc OOMs), #18435, #12711, #10451, #10444. None covers plugin-hono-server or the workspace lane.

    File surface: packages/plugins/plugin-hono-server/tsconfig.json (either skipLibCheck: true or extends the shared tsconfig.base.json, which since #26203 is the packages' base; whichever keeps its emitted dist/ byte-identical), plus one root .changeset/ entry only if the emitted output of a published package changes. The sweep of the other workspace tsconfigs that extend nothing (apps/docs, examples/app-{crm,multi-package,showcase,todo}, packages/cli, packages/create-objectstack + its templates/blank, packages/qa/{dogfood,downstream-contract}) is MEASURE-AND-REPORT only: peak RSS and the lib-check-only errors the flag would hide, in the report, no edit. ⛔ No raised heap limit (--max-old-space-size, NODE_OPTIONS) in place of the fix; ⛔ no ui/ path, no .github/**, no root ci.yml (stop on breach; explain in the report)

    Premise: P1 holds: plugin-hono-server/tsconfig.json on main extends nothing and sets no skipLibCheck, while tsconfig.base.json and the root tsconfig.json both set it. P2 holds: no open PR touches any tsconfig.json or any plugin-hono-server path (checked across all open PRs at 22:25Z)
    Serial constraints cleared: #26339 (root program, in review) and #26267 (vitest.config.ts files, in review) touch no tsconfig this card edits

    devx seat 2 · review: ACCEPT → PR #26356 (Fixes #26288) comment 6429559527 on head 3db795be75. Every check is green or skipped (36 success, 16 skipped). Not governed, under the human-merge threshold. Landing: ready + auto-merge.
