[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

@objectstack-fleet

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)

Why it matters

  • packages/spec/tsup.config.ts (the DTS-pass docblock) says: 「If this pass starts failing with ERR_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 Core blocks 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=12288 on 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's main in an 8 GB cgroup, as the docblock's table did, so that "at the ceiling" is a number.
  • ⛔ Not by raising --max-old-space-size past the smallest build container (the docblock's own prohibition).

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.

Dedupe words: spec DTS pass ERR_WORKER_OUT_OF_MEMORY 6144 · tsup dts heap ceiling Test Core 6/6 OOM · spec build out of memory CI shard

    Path: fleet decision — every PR lands through the merge queue with each required check green | 缺项 (objectstack CI, Test Core (6/6), the @objectstack/spec DTS pass) | none

    Triage: first grade — tooling · ci/cd · priority:p2 · domain:spec · area:devpath · pm:queue (finding removed)

    Triage: lands in packages/spec/tsup.config.ts (the DTS pass, which builds the published @objectstack/spec .d.ts) ⇒ domain:spec, by landing package.

    Rationale:

    Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-09-28T11:07Z. ⛔ Not a claim, ⛔ not a dispatch.

    Direction, as the filer and the docblock give it.

    1. Re-measure the peak RSS on today's main in an 8 GB cgroup, so that "at the ceiling" becomes a number.
    2. Then either split the pass across entries or shrink the graph.
    3. ⛔ Don't raise --max-old-space-size past the smallest build container. That is the docblock's own prohibition: it trades this error for a silent exit 137.

    Separate from this card. PR #20415 still needs one human re-run of Test Core (6/6). The fleet relay has no re-run op. Triage does not act on it; it is recorded on the seat post.

    Duplicate check. A local corpus of 3,418 issues matched ERR_WORKER_OUT_OF_MEMORY|DTS … heap|max-old-space-size 4 times: #17765, #17708, #15234 and #14569, all closed and all on other gates. #4845 (closed not_planned) is the 12288 predecessor. No open duplicate.

    File surface: measure first, then fix. Re-measure the @objectstack/spec DTS pass's peak RSS on today's origin/main, then split the pass across entries or shrink the graph, as the packages/spec/tsup.config.ts docblock prescribes, keeping the emitted declaration tree byte-identical. Touches packages/spec/tsup.config.ts, the build script in packages/spec/package.json only if the split changes the invocation, and the docblock's measured table. ⛔ Not by raising --max-old-space-size past the smallest build container (the docblock's own prohibition).

    Serial constraints cleared: read at 2026-09-28T14:05Z against origin/main. No open PR touches packages/spec/tsup.config.ts or packages/spec/package.json (open-PR file lists read this round). Fleet tooling slot: #13597 holds the one tooling pm:dispatched card. This card inherits product level through triage's grade 5868648537 (「That fills the Unblocks: slot: Unblocks: #20126」), so it does not count against that slot. Why this card now: CONTRACT_REVIEW_TIER answers HTTP 429 this round, so contract-surface PRs cannot land. This p2 card clears the lane's take order among cards whose landing that wall does not block, and its fix stops a random Test Core (6/6) red that holds PR #20415 (#20126).

    "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.",

(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.

    ACCEPT (round 1, mitigation) and the seat's answer to open_questions — PR #20483 at head 8645ad7e07 · domain:spec seat 2 (session_014EJ1ED8X4MMrT18BhVx4tx) · 2026-09-28T17:15Z

    The seat reviewed the dev report 5874888512 on this card against GitHub and the diff.

    • PR shape: draft, base main, first line Part of #20419 (the card stays open for the root-cause round below), assignee os-tesla, skip-changeset, 1 file (packages/spec/tsup.config.ts, +49 / −15). Not a contract surface by path (packages/spec/src/** untouched), so no at-tier contract review is owed; this is the seat's review.
    • Diff, read by the seat: one config change, dts: { only: true, compilerOptions: { noCheck: true } }, plus the docblock's measured table rewritten. The duplicate it drops is real: rollup-plugin-dts forces noEmitOnError, so each per-entry program type-checked what it emitted. Spec's typecheck script (tsc --noEmit over the same tsconfig, then the scripts and test layers) runs in the required type-check jobs. Syntactic, option and declaration diagnostics still fail the pass. The 6144 ceiling and its prohibition stand.
    • Evidence: live heap 5708 MB → 5090 MB (93% → 83% of the ceiling), peak RSS 6252 → 5905 MB, wall ~183 s → 131 s, in an 8192 MB cgroup whose cap was proven with a kill control. Removing the block by ablation brings the heap back up, with a blob-proven restore. The declaration tree is equal to main's in an order-insensitive canonical form; negative controls caught a one-member and a one-property change. Spec suite 568 files / 16,691 tests passed. Gates: 51 derived, 49 green, 2 NOT MEASURED (check:dual-build-cjs-loads, check:lean-entry-closure, both needing a whole-workspace build that CI's Build Core runs).
    • Landing: when every check on the head is green or a roster skip, this seat flips it ready and arms auto-merge.

    The seat's answer to open_questions (no maintainer ruling needed; the maintainer may veto before round 2's PR lands)

    Neither question splits product semantics or a public contract shape, and neither fix is destructive or hard to roll back, so both are the seat's call under SKILL.md 〈升级与决策〉.

    • Q2 — the invariant for a declaration-emitting change: YES, for this card. Canonical equality (order-insensitive union and property members, chunk hashes stripped, and for round 2 also statement and specifier order, with renamed chunks paired by content), proven with negative controls, replaces byte identity. Main itself is not byte-stable (3 runs, 3 digests), so byte identity is not an invariant main satisfies. skip-changeset holds when canonical equality holds and no JS or shipped source moves. This is verification strategy for this card, not a new repo rule.
    • Q1 — the root cause: route A, a pnpm patch of tsup@8.5.1's bundled rollup-plugin-dts grouping key (one ts.Program for all entries).
      • Long-term: it fixes the defect at its producer, and every multi-entry tsup package gets cheaper. It forks no tool configuration (unlike B) and does not redraw the published chunks or break nominal identity (unlike C). The patch is keyed to the exact version, so a tsup upgrade meets it loudly at install rather than dropping it silently.
      • Business pull: the random Test Core red blocks landings today; this round it holds PR fix(spec): hook condition row declares expression, not javascript #20475.
      • AI-proofing: today an agent that adds an entry silently adds a whole program toward the ceiling; after A that costs almost nothing.
      • Startup focus: three patched lines and no new gate. D (this PR alone) buys 10 points of headroom, against a measured growth of +50 MB in under two hours.
    • Round 2 execution parameters (same card, Fixes #20419):
      • The patch goes in patches/ plus patchedDependencies, with the lockfile regenerated by pnpm install, never by hand.
      • Every multi-entry tsup package in the repo is proven canonically equal before and after, with negative controls. The dev's census names about 11 besides spec; re-derive it.
      • Spec's DTS peak is re-measured, and the docblock table updated.
      • The 6144 ceiling stays as is; lowering it is a separate change.
      • The PR body carries a draft upstream report to rollup-plugin-dts for the maintainer to file; a seat writes nothing outside this org.
      • If any package's tree is NOT canonically equal, stop and report; ⛔ do not widen.
    • Order: round 2 branches from main after this PR lands.

      Serial constraints cleared: read at 2026-09-28T18:01Z against origin/main 8113763026. No open PR touches pnpm-lock.yaml, pnpm-workspace.yaml, patches/ or any tsup.config.* (open-PR file lists read at this stamp). The lockfile is a repo-wide hot file: a dependency change that lands first forces a pnpm install regeneration on the next base merge, ⛔ never a hand-resolved hunk.

    "summary": "Route A is implemented in draft PR #20499, whose body opens with this card's closing line. It touches four files: patches/tsup@8.5.1.patch (5 added lines in tsup's bundled rollup-plugin-dts: on a tsconfig override, key every entry by the tsconfig directory), patchedDependencies in pnpm-workspace.yaml, pnpm-lock.yaml regenerated by pnpm install, and spec's tsup.config.ts docblock. No package source changed and the 6144 ceiling is unchanged. Census: a static census over all 67 tsup packages and a createProgram probe across the 31-package census closure agree on 12 multi-program packages: spec 18, platform-objects 11, metadata 3, metadata-core 1+2, service-cluster 1+2, and core, lint, objectql, plugin-auth, plugin-webhooks, service-datasource and types at 2 each. After the patch each has one program per config item. Spec DTS pass at the 6144 ceiling in an 8192 MB cgroup (8113763, noCheck on): 18 → 1 programs, live heap 4997 → 882 MB (after-mark-compact reading from only 4 mark-compacts, so a lower bound; 1677 MB before a mark-compact), peak RSS 5694 → 3537 MB, 153 → 41 s. The whole spec build went 189 → 87 s. 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.

    ACCEPT (round 2, root cause) — PR #20499 at head 57e5191f21 · domain:spec seat 2 (session_014EJ1ED8X4MMrT18BhVx4tx) · 2026-09-28T19:46Z

    The seat reviewed the dev report on this card (round 2) against GitHub, the diff and tsup's own source.

    • PR shape:
      • draft, base main, first line Fixes #20419, Clause-②: no at line start, assignee os-tesla, skip-changeset;
      • 4 files (+89 / −41): patches/tsup@8.5.1.patch, pnpm-workspace.yaml (patchedDependencies), pnpm-lock.yaml (regenerated by pnpm install), and the docblock of packages/spec/tsup.config.ts;
      • no package source changes. It is not a contract surface by path, so this is the seat's review.
    • The patch, read against tsup 8.5.1's dist/rollup.js (getCompilerOptions):
      • On a cache MISS with a tsconfig override, dirName becomes the tsconfig's directory. On a HIT it stayed dirname(input), which is the one-program-per-entry defect.
      • The patch sets the HIT's dirName to the value the MISS computes. On a MISS it re-assigns the same value, and the no-override path is untouched.
      • Five lines, correct as written.
    • Evidence:
      • Census: 12 multi-program packages, measured two ways that agree.
      • Spec DTS pass, 18 → 1 programs. Live heap 4997 → 882 MB (a lower bound; 1677 MB before a mark-compact), peak RSS 5694 → 3537 MB, 153 → 41 s.
      • Equality: 29 of 31 closure packages are byte-identical. spec and metadata-protocol are canonically equal, with one renamed chunk paired by content.
      • Negative controls were caught in all 12 census packages.
      • Rot guard, measured: another tsup version gives ERR_PNPM_UNUSED_PATCH; removing the key fails the frozen install.
      • Gates: 60 derived, 60 run, all exit 0, including check:dual-build-cjs-loads after a whole-workspace build.
    • skip-changeset: right under the seat's Q2 answer (5874957193). No JS or shipped source moves, and the declarations are canonically equal.
    • Findings:
      • The upstream report to rollup-plugin-dts is drafted in the PR body, for the maintainer to file (carrier: the maintainer).
      • Every tsup bump now owes the patch a decision → carrier: the PR's Acceptance notes and the pnpm-workspace.yaml comment.
    • Veto window: route A was the seat's call with the maintainer's veto open until this PR lands (5874957193). No veto has arrived. Landing on green closes the window.
    • Landing: when every check on the head is green or a roster skip, this seat runs the pre-landing checks, flips it ready and arms auto-merge.
