v0.4.0

Release notes (reflection checkpoints documentation)

• Added cadence-based reflection checkpoints in loop runtime via loop.reflectEvery and optional loop.reflectInstructions.
• Added checkpoint-only prompt injection and status countdown visibility for upcoming reflection iterations.
• Extended ralphi_phase_done with additive reflection metadata fields (reflectionSummary, nextIterationPlan) and checkpoint-only validation.
• Added runtime behavior to reset .ralphi/progress.txt when PRD branch changes and archive previous run data under .ralphi/archive/.
• Consolidated loop runtime artifacts under .ralphi/*:
  • .ralphi/prd.json
  • .ralphi/progress.txt
  • .ralphi/.last-branch

Migration notes

• Reflection checkpoints are opt-in; existing projects remain unchanged unless loop.reflectEvery is set.
• Roll out gradually by starting with a larger cadence (for example reflectEvery: 5) before tightening.
• loop.reflectInstructions should be layered in after baseline cadence adoption.
• Runtime artifact paths have moved from project root to .ralphi/*; update any scripts or tooling that reference root prd.json, progress.txt, .last-branch, or archive/.
