[finding] @objectstack/spec's DTS pass hit its 6144 MB heap ceiling in CI (ERR_WORKER_OUT_OF_MEMORY, Test Core 6/6) on a PR whose diff adds nothing to that pass #20419
Description
Filing gate: ① a defect with a named landing site, finding class (b). The spec build's DTS pass declares a heap ceiling that its own docblock says must hold, and on CI it did not hold. reach: was measured on one CI run, below. Filed by domain:spec seat 4 (session_01ARcDurZ5j34RdqsGgc4jgH, seat post #18917) while reviewing PR #20415. ⛔ Filed bare: routing and grading belong to triage. ⛔ Not a claim.
What happened (measured)
-
PR test(spec): the currency-mode family's enumerating closure pin (#20126) #20415 (class-closure(currency-mode): every site that reads or teaches defaultCurrency without the currencyMode 'fixed' condition, or cites ADR-0053 for currency — spec describe, dashboards skill, data-api docs, analytics comments #20126), head
7fc9f86b.Test Core (6/6), job108869603141(run36404384622), 2026-09-28T09:36–09:38Z. The step@objectstack/spec:buildfinished its ESM and CJS passes, startedDTS Build start, and 114 s later printed:Error [ERR_WORKER_OUT_OF_MEMORY]: Worker terminated due to reaching memory limit: JS heap out of memoryIt exited 1, so the shard ran no test body.
-
The PR's diff is outside that pass. Its four files are:
packages/spec/src/data/currency-mode-family-closure.pin.test.ts, whichpackages/spec/tsconfig.jsonexcludes ("exclude": [..., "**/*.test.ts"]);packages/spec/vitest.repo-tests.json;scripts/cross-package-test-inputs.mjs;turbo.json.
None of them enters the declaration program.
-
Controls on the same base:
mainat40b315b0:Test Core (6/6)success.- PR feat(automation)!: edge-branched decision is exclusive; mode: 'inclusive' takes every branch (#15429) #20344 at
b30325bb, a merge of40b315b0: all 33 checks success, shard 6 included. 7db1332f,65352b7dand34ec30d4: shard 6 success.
So the ceiling is not exceeded on every run. It is exceeded on some runs over essentially the same declaration graph: the pass now sits at the ceiling.
Why it matters
packages/spec/tsup.config.ts(the DTS-pass docblock) says: 「If this pass starts failing withERR_WORKER_OUT_OF_MEMORY, the live type graph has outgrown 6144 — that is a loud, actionable failure and the point of the ceiling. ⛔ Do not "fix" it by raising the number past what the build container has; that trades this error back for the silent exit 137. Shrink the graph, or split the pass across entries.」- Its measured table (peak RSS 5794 MB at the 6144 ceiling; 4096 fails) predates the growth since. The spec graph keeps growing with every retirement tombstone and schema.
- A random red
Test Coreblocks enqueue for whichever PR draws it. A seat cannot re-run a job (the fleet relay has no re-run op), so the PR sits red until a human re-runs it or an unrelated push re-triggers CI. - Predecessor: CI infra:
@objectstack/spec的 DTS 构建贴着 runner 内存天花板 —— 每个 spec PR 首跑都被 OOM 杀掉一次(--max-old-space-size=12288on a 16GB runner) #4845, closed. It was the same pass against the runner's memory at a 12288 ceiling; the 6144 ceiling and the docblock came from it.
Where the fix lands (for the dispatch to confirm)
packages/spec/tsup.config.ts, the DTS pass: split it across entries as the docblock prescribes, or shrink the graph. First re-measure the peak on today'smainin an 8 GB cgroup, as the docblock's table did, so that "at the ceiling" is a number.- ⛔ Not by raising

Dedupe: #4845 (closed, the 12288 episode) is the only prior hit for ERR_WORKER_OUT_OF_MEMORY / spec DTS heap. #17708 and #14569 are tsc heap ceilings on other gates.

"premise_still_valid": true,
"summary": "The premise was measured and holds. The spec DTS pass ran alone at its 6144 MB ceiling inside an 8192 MB cgroup-v1 memory cgroup, with live heap read as the largest heap kept after a V8 mark-compact (--trace-gc). At 8cdbe0c the live heap was 5633-5658 MB (92% of the ceiling), peak RSS 6161-6177 MB, wall 181-194 s over 3 runs. At ec6a275 (the base with main dc0ab6a merged) the live heap was 5708 MB (93%), with a 5984 MB pre-GC peak against the 6192 MB worker limit. That is +50 MB over the 12 commits of 1h43m. ROOT CAUSE (measured): tsup 8.5.1 bundles rollup-plugin-dts 6.1.1, and its createPrograms builds ONE ts.Program PER ENTRY. tsup always passes the tsconfig path, and on a config-cache hit the plugin keys each later entry by its own directory; the code is unchanged in the latest rollup-plugin-dts 6.5.1. Evidence: a createProgram probe counted 3 programs for 3 entries. Heap grows with entry count: single entries are 330-810 MB, the halves 3261 and 1442 MB, all 18 entries 5658 MB, while whole-package tsc --noEmit is 1103 MB. A tsup copy with the key corrected built 1 program with 18 roots: 1379 MB live, 53 s. PR #20483 (draft, Part of) lands a mitigation inside the card file surface: compilerOptions.noCheck on the DTS pass. rollup-plugin-dts forces noEmitOnError, so every program type-checked each file it emitted, a duplicate of the typecheck job. With noCheck the live heap is 5090 MB (83%), peak RSS 5905 MB, 131 s at ec6a275. The emitted tree matches main under an order-insensitive comparison. The dispatch invariant of a byte-identical tree is unmeasurable: main itself emitted 3 different digests over 3 runs (union and enum-object member order). The docblock now records this. DECISION NEEDED: the root-cause fix (one program) moves statement order and one chunk name in spec, and the same kind of change reaches about 11 other multi-entry tsup packages. The dispatch routes a dist change to a different card, so it is open_questions[0], not in this PR.",
"tests": "Final head 8645ad7. (1) pnpm --filter @objectstack/spec build inside the 8192 MB cgroup: exit 0, peak anon RSS 6000 MB, 169.4 s, DTS "Build success in 127980ms". check-dts-emitted "36/36 declared declaration file(s) present". check-dts-references "130 declaration file(s) reachable from 36 declared entry point(s); 394/394 relative reference(s) resolved". (2) pnpm --filter @objectstack/spec exec vitest run --project local --maxWorkers=2 under the verify lock: "Test Files 568 passed (568) / Tests 16691 passed | 1 todo". The 8 test files that read tsup.config.ts as text also ran on their own: 130 passed. (3) typecheck NOT RUN, argued by construction: tsup.config.ts is in none of spec's three tsc programs (tsconfig.json and tsconfig.test.json include src//*, tsconfig.scripts.json includes scripts//*). (4) Reverse verification from the committed state: scripts/ablation-replace.mjs removed the compilerOptions block (anchor x1 → x0, blob 0bc508b29eab → 16001c6a9895). DTS pass as on main: live 5708 MB, peak RSS 6252 MB, 182.8 s. With noCheck: live 5090 MB, peak RSS 5905 MB, 131.0 s. Restore: blob == HEAD 0bc508b29eab and git diff HEAD empty, re-checked by git hash-object. Expected direction observed: heap up without noCheck. (5) Tree equivalence, order-insensitive (TS re-print with union members and property-only type literals sorted, chunk hashes stripped). At 8cdbe0c: main run b, main run c and noCheck share canonical digest fada441d with 0 files differing, while their byte digests are 5cf3234c, 6fd2cecf and 2cabf1ba (run a 7bf19190). At ec6a275: main behaviour, noCheck and the full-build tree share canonical 54537aa9 with 0 files differing. Negative controls (one renamed union member, one deleted property) were caught, naming exactly 1 and then 2 files. (6) Instruments: the cgroup limit was proven by a 200 MB allocation killed with exit 137 under a 64 MB cap. systemd-run was not used; the cgroup-v1 memory controller was written directly as root. --trace-gc went on argv because NODE_OPTIONS refuses it.

The emitted types are unchanged; that needs an order-insensitive comparison that also sorts top-level statements and import/export specifiers and pairs one renamed chunk (data-engine ↔ analytics.zod) by content. Which route?",
"options": [
"A — pnpm patch of tsup@8.5.1 (its dist/rollup.js bundles rollup-plugin-dts): on a config-cache hit, key the entry by the config's directory. Three lines, plus patchedDependencies in pnpm-workspace.yaml, patches/, the lockfile, and an upstream report to rollup-plugin-dts. Repo-wide: about 11 other multi-entry tsup packages (core, objectql, metadata with 6 entries in 4 dirs, types, plugin-auth, plugin-webhooks, service-cluster, service-datasource, metadata-core, lint, create-objectstack) also drop to one program and reorder their emitted d.ts, which needs the same equivalence proof per package. This would be the repo's first pnpm patch.",
"B — a spec-local DTS script calling rollup plus rollup-plugin-dts@6.1.1 directly without the tsconfig override (new devDeps rollup and rollup-plugin-dts, about 60 lines, a build-script change). Spec-only blast radius, but it duplicates tsup's DTS configuration and drifts from it.",
"C — split the pass across entry groups. Measured: halves peak 3261 / 1442 MB. But the chunks are redrawn (60 + 32 files vs 128) and declarations are duplicated across entries, which breaks nominal identity for classes and unique symbols. It publishes a different surface.",
"D — keep only this PR's noCheck: 83% of the ceiling. At the +50 MB per 1h43m measured today, the headroom is not durable."
],
"recommendation": "A. Business need: the random Test Core red is real and blocks landings. Long-term: it removes the defect at its producer, and every multi-entry package gets cheaper. B forks tool configuration, C degrades the published surface, and D is temporary. AI-proofing: an agent adding an entry today silently adds a whole program; after A it costs almost nothing. Startup focus: three patched lines, no new gate. The cost to accept: a one-time reorder of d.ts statements and chunk names in about 12 packages, which is the same class of noise as main's own byte instability. Land #20483 now regardless: it is independent and helps under every option."

"question": "The acceptance invariant for declaration-emitting changes: byte identity cannot hold, because main is not byte-stable.

Equality: 29 of 31 closure packages are byte-identical before and after, including 11 of the 12 census packages. spec (130 files) and metadata-protocol are canonically equal with 0 files differing, and one spec chunk is paired by content (data-engine ↔ analytics.zod). Negative controls were caught in all 12 census packages, on an entry file each plus a chunk in lint, metadata-core, objectql and spec. Rot guard, measured with pnpm 10.31.0: tsup moved to 8.5.0 gives ERR_PNPM_UNUSED_PATCH (and a frozen install gives ERR_PNPM_LOCKFILE_CONFIG_MISMATCH); removing the yaml key makes the frozen install refuse.",
"tests": "Heads: before-trees at 8113763 (unpatched), after-trees at 78cbf5d (patched; the same source for every package), and gates, builds and tests at the merged head 57e5191 (branch plus origin/main fc0db22). (1) Instruments: a cgroup-v1 memory cgroup capped at 8192 MB (round 1 proved the cap kills first); --trace-gc for the largest heap after and before a mark-compact; a createProgram probe preloaded into the tsup DTS worker only (measurement, no argument or return changed). (2) Canonical comparison: a TypeScript re-print sorting union members, property-only type literals, top-level statements and import/export specifiers; chunk hashes stripped; chunks paired by unique chunk-name-agnostic content. canon-dts2 on all 31 packages reported PAIRING problems=0 and FULL-CANON-DIFF 0 for each. For spec, "RENAMED chunks (B → A): analytics.zod → data-engine" and "FULL-CANON-DIFF after rename: 0 file(s)". With statement sort off, spec shows 20 files differing, the same kind as in round 1. (3) Negative controls: the first real string type node became number, located by the parser and never in a comment. Every run named exactly the mutated file: core, lint (+chunk runtime-HASH.d.cts: "no partner"), metadata, metadata-core (+chunk repository), objectql (+chunk util), platform-objects (identity/index.d.ts, because index.d.ts only re-exports; the first attempt pointed at a directory, errored, and was redone), plugin-auth, plugin-webhooks, service-cluster, service-datasource, types, spec data/index.d.mts, and spec's renamed analytics.zod chunk (pairing failed: "no partner in A for analytics.zod-…", diff = data-engine-HASH.d.ts). (4) Rot: scratch projects on packageManager pnpm 10.31.0 with the same patch file and key. On tsup 8.5.1, install exit 0 and the patch marker is present once. On tsup 8.5.0, install exit 1 with "ERR_PNPM_UNUSED_PATCH The following patches were not used: tsup@8.5.1", and the frozen install exits 1 with ERR_PNPM_LOCKFILE_CONFIG_MISMATCH. In-tree, scripts/ablation-replace.mjs deleted the yaml block (anchor 1 → 0) and pnpm install --frozen-lockfile exited 1 with ERR_PNPM_LOCKFILE_CONFIG_MISMATCH; the restore blob equals HEAD b96f61f907d3 and git diff HEAD is empty. (5) spec tests that read tsup.config.ts as text: "Test Files 8 passed (8) / Tests 130 passed (130)". Full spec suites were not re-run: no source changed, and the declarations are canonically equal.",
