Philosophy
This repo follows a geological/spiritual landscape metaphor:
| Layer | Meaning | Contents |
|---|---|---|
| PILLARS | Permanent, load-bearing, current | The whole substrate of FROM House |
| TANK | Cold storage, deep archive | Retired tools, references, knowledge artifacts |
| TANK/LITHS/ | Archaeological sediment | Frozen snapshots of PILLARS at significant moments |
One source of truth. PILLARS is the single canonical tree. There are no parallel “live” mirrors. Versioning happens inside PILLARS via frontmatter, archive subdirs, and README status sections.
