Persistent memory that survives between separate ralph-starter runs: - Reads .ralph/memory.md at loop start and injects into agent context - Saves a run summary (task, result, iterations, cost) after each run - Agent can also write to memory.md to record project conventions - Auto-truncates to 8KB to keep context usage reasonable Exported as SDK API: readProjectMemory(), appendProjectMemory() Closes ENG-1555 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Replace predictable tmpdir + Date.now() pattern with mkdtempSync to resolve CodeQL "Insecure temporary file" alert. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The memory test file used mkdirSync but did not include it in the node:fs import, causing TypeScript compilation to fail. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
