+# Task: Diagnose Next.js production image build failure
+
+## Identity
+
+- Task ID: 20260818-next-build-7f3a
+- Mode: Feature
+- Branch: main
+- Worktree: D:\Datas\OthersProjects\openmaic
+- Base commit: a76c8d2613c6ab6e0c661fbfd574803c2b09fc44
+- Owner: developer
+- Status: Ready for integration
+
+## Scope
+
+- Diagnose the Jenkins/Docker failure at `OpenMAIC/Dockerfile:64` (`RUN pnpm build`).
+- Reproduce the repository's production webpack build where the local environment permits,
+  and distinguish a source/build regression from a runner resource or timeout failure.
+- Do not change application or Docker build behavior without the missing Jenkins/Docker
+  termination evidence.
+
+## Intent And Constraints
+
+- The supplied log stops after `Creating an optimized production build ...` and only shows
+  a bare `ELIFECYCLE Command failed`; it does not contain the terminating signal or compiler
+  diagnostic.
+- The repository's `pnpm build` first requires the generated
+  `public/vendor/maic-importer/index.js`; the Docker dependency stage normally creates it via
+  postinstall, so a missing local copy must not be confused with the reported Docker failure.
+- Preserve the clean source worktree; generated package dist files and `.next` output are
+  diagnostic artifacts only.
+
+## Outcome
+
+- The local Windows `pnpm build` initially stopped at the expected vendor guard because the
+  ignored postinstall artifact was absent. After generating ignored workspace dist outputs and
+  syncing the vendor bundle, the equivalent direct Next command completed successfully:
+  `node --max-old-space-size=8192 node_modules/next/dist/bin/next build --webpack`.
+- The successful build compiled webpack in about 4.8 minutes, used roughly 5.7 GB working set
+  at peak sampling, then finished TypeScript, 56 static pages, traces, and standalone output.
+- A second direct build with a 4096 MB V8 heap also completed successfully, but webpack took
+  about 5.4 minutes and the process used roughly 3.8–4.1 GB working set.
+- The generated Next trace from the successful run records `run-webpack` at 326.806 seconds
+  and total `next-build` at 397.158 seconds; the trace and generated outputs were removed after
+  verification because they are ignored build artifacts.
+- The middleware deprecation warning appeared in both successful builds and is not the failure.
+- A subsequent Jenkins run again stopped at `#22 308.2` immediately after
+  `Creating an optimized production build ...`, with the same bare `ELIFECYCLE` and no
+  compiler/OOM diagnostic. The repeatable ~5-minute cutoff strengthens the external build-step
+  timeout hypothesis; it still does not identify the signal without Jenkins/Docker metadata.
+- The evidence is consistent with a Jenkins/Docker memory ceiling or build-step timeout killing
+  webpack before it emits a compiler error. The exact external cause remains unverified because
+  the Docker daemon and Jenkins host logs are unavailable in this workspace.
+- The build script in `OpenMAIC/package.json` now caps the V8 heap at 4096 MB instead of
+  8192 MB. This is a mitigation for the observed host-level memory pressure, not proof that
+  the external 5-minute termination was the sole cause.
+
+## Verification
+
+- `check_project_docs.py` passed.
+- `task_context.py status --json` confirmed this task owns the clean main worktree.
+- Direct Next webpack build with 8192 MB heap: passed, full route output and exit code 0.
+- Direct Next webpack build with 4096 MB heap: passed, full route output and exit code 0.
+- Read-only final diagnosis review: PASS; the reviewer agrees the evidence supports an
+  external timeout/resource termination hypothesis but cannot distinguish timeout from OOM.
+- `git status --short --untracked-files=all`: only this task record remains untracked; temporary
+  generated source changes were restored.
+- Docker daemon/engine is unavailable locally, so an end-to-end image build was not reproduced.
+- Follow-up Jenkins log: same failure signature at approximately 308 seconds.
+- The later diagnostic-script run ended with `ERROR: failed to solve: Canceled: context canceled`
+  and script exit code `124`; this is the script's own `timeout 900s`, not a compiler exit.
+  Its cgroup reported an effectively unlimited `memory.max` and `oom_kill 0`. The kernel output
+  contained a historical BuildKit Node OOM at 21:46:05 (about 6.3 GiB RSS), which proves the
+  7.3 GiB host has previously exhausted memory but is not timestamped to the 22:38 run.
+- `OpenMAIC/package.json` parses successfully after the heap-cap change; `git diff --check`
+  reports no whitespace errors.
+- Read-only implementation review: PASS; the reviewer found the one-line heap reduction and
+  proposed Jenkins observability/timeout wrapper consistent with the available evidence.
+
+## Follow-ups
+
+- Re-run Jenkins with untruncated output (`docker build --progress=plain`) and capture the final
+  30 lines plus the shell/Docker exit code.
+- Check the build node/container memory limit (`/sys/fs/cgroup/memory.max`, `docker stats`, or
+  Jenkins host metrics) and whether the job has a five-minute command timeout. The repeated
+  ~308-second cutoff makes that timeout the first check. Budget at least
+  6–8 GiB for this webpack build and a timeout above the observed ~6-minute end-to-end duration.
+- Run the updated Jenkins command with `--progress=plain`, a 900-second per-image timeout, and
+  failure diagnostics for cgroup memory and kernel OOM evidence. Jenkins' own job timeout must
+  also exceed 15 minutes; a shell-level timeout cannot override a shorter Pipeline/plugin limit.
+
+## Promotion Candidates
+
+- None. This investigation does not establish a source or Docker configuration change without
+  the external termination signal.
