📐 Maintainability & Code Quality | 🔵 Trivial | ⚖️ Poor tradeoff
Non-blocking: the fallback heap resolver differs from the canonical helper.
The canonical resolveHeapSizeMb handles the argv percentage and the env percentage in separate branches. If the argv percentage is valid, it is the only percentage used. The fallback handles them together with argvPercentage ?? envPercentage. The results match for valid values.
The fallbacks do differ from the canonical helper in two other ways:
fallbackFindEqualsFlagValuehas no guard against an empty--max-memoryvalue, butfallbackParsePositiveIntegerMbreturnsnullfor it. This matches the canonical helper.- The canonical helper takes
availableBytesandmemorySourcesas inputs. The fallback ignores them. This is acceptable for a launcher-only fallback.
No change is needed. The comment at Lines 17-24 already says the fallbacks must stay in sync. Consider a test that runs both implementations on the same inputs and compares the results. That test would catch future drift.

Summary
bin/openclaudeno longer statically imports itsbin/*.mjssiblings../node-compile-cache.mjsand./heap-limit.mjsnow load via dynamicimport()with self-contained inline fallbacks, so layouts that install only the launcher file boot instead of crashing withERR_MODULE_NOT_FOUNDbefore any code runs./usr/lib/openclaude/bin/openclaudewithout its sibling helpers (issue unable to run after install (ARCH) #2255); the static ESM imports made that layout unbootable, including--helpand the missing-distguidance path.Fixes #2255.
