# Archived Notes

This directory holds historical ledgers, closed migrations, optional bridge
plans, superseded design splits, and one-off prompts. These files are not
current authority unless a top-level canonical note explicitly points here for
source history.

## Quarantined Documents

- `architecture-rationale.md`: original rationale for map/scratch/evidence.
- `codex-repository-algorithmic-map.md`: Codex source inventory from an earlier
  extraction pass.
- `epiphany-architectural-teardown.md`: host-seam suspicion pass; useful scar
  tissue after the rebuild, not a current work queue.
- `epiphany-distilled-agent-doctrine.md`: older doctrine distillation superseded
  by `AGENTS.md`, `../epiphany-anatomy.md`, and prompt-owned specialist files.
- `epiphany-ideal-architecture-rebuild-plan.md`: completed May 2026 foundation
  migration blueprint.
- `epiphany-planning-substrate.md`: planning product model source history after
  the runtime and GUI planning slices landed.
- `epiphany-rider-unity-integration-plan.md`: optional Rider/Unity bridge plan,
  quarantined until engine-repo work resumes.
- `json-contamination-ledger.md`: historical classification ledger for JSON
  purification work.
- `repo-fractal-dataflow-cache-plan.md`: repo-memory profile plan superseded by
  the unified memory graph direction.
- `agent-memory-fractal-cache-plan.md`: agent-memory profile plan superseded by
  the unified memory graph direction.
- `true-epiphany-memory-migration-sandbox-prompt.md`: one-off migration sandbox
  prompt.

into a top-level note and leave the archive as provenance.
