  // on the model choosing to read it. Mirrors the AGENTS.md startup instruction.
  // The system is merged (9 files in prompt-system/ plus AGENTS.md; was 39: bootstrap.txt + 38 modules; 2026-08-31 cycle-removal pass,
  // then restoration pass to 9 files). All files are pinned so module loading is
  // fully deterministic. Phase-specific additions are diligence-loaded by the
  // agent reading 00-system.md's load rules.
  // Entries are explicit paths, never globs.
  // AGENTS.md is the sole entry point; prompt-system/ files follow its load order.
