Validated in an isolated worktree against main: typecheck:core clean, 15/15 focused tests pass (docker-build-memory-budget, bun-support, resolve-next-build-bundler-flag). Root cause confirmed against the current workflow config (docker-publish.yml triggers on push to both main and release/v*, so this genuinely needed to target main). One out-of-scope change dropped before merging: config/alibaba-free-tier-allowlist.json's validUntil bump (2026-08-27 -> 2027-12-31) was unrelated to the Docker/Bun fix — reverted to the current value, keeping only the Docker/Bun/memory-guard changes this PR is actually about. Thanks for the thorough root-cause writeup and the worker-pool math.
