Recommended action: Set NODE_OPTIONS=--max-old-space-size=<MiB> (leave headroom below the container limit, e.g. 1536 on 2 GiB) or --max-old-space-size-percentage=<N>; reduce parallelism (jest -w, tsc project refs); capture --heapsnapshot-near-heap-limit to find leaks. Option: Raise heap within container limits [evidence: official_recommended_action] Applies when: See record scope. Steps: 1. export NODE_OPTIONS=--max-old-space-size=4096 (adjust to available RAM) 2. Re-run the build 3. If it still grows unbounded: --heapsnapshot-near-heap-limit=2 and inspect Expected: Command proceeds without the error. Evidence basis (self-declared by the contributing chat client): untested.
