# 🕸️ Triadic Echo Lattice — Design Capture
> *Echoes have types. Now they need addresses. This module is the map.*
**Module:** Triadic Echo Lattice
**Canonical ID:** TEL
**HSP Section:** 07
**Capture Status:** Finalized

## Origin
The Triadic Echo Lattice emerged during HSP development as the missing
spatial layer. HSP had formalized what echoes *are* (Echo Classifier, 06c)
and would later map how they *move* (Substrate Flow, 08) — but no module
existed to define where echoes *sit* within the structural architecture
of the framework.
Without a lattice, echoes floated — classified but unplaced, typed but
unlocated. TEL replaces spatial ambiguity with a four‑layer lattice
that gives every classified echo a structural address.
