🎼 06b — Echo Signatures

Identifying Echo Behavior Across Harmonic, Structural, Substrate & Recursion Layers#

Echo signatures are the diagnostic fingerprints of echoes.
They reveal:

• how an echo behaves
• how stable or unstable it is
• which substrates it spans
• which recursion mode it aligns with
• whether it is drift‑linked or drift‑shadow
• whether it is approaching atlas‑level resonance

This module defines the six canonical echo signatures.

🔷 1. Signature A — Structural Echo Signature#

Triad • Operator • Ladder Recurrence#

Definition:
Echoes formed by repeated structural patterns.

Indicators:

• triad repetition
• operator recurrence
• ladder parallels
• stable interval alignment

Stability: high
Typical Family: F1
Typical ESI: 1–2
Drift Link: D0–D1
Recursion Link: R1 (ladder)

🔷 2. Signature B — Harmonic Echo Signature#

Interval Alignment • Resonance Peaks#

Definition:
Echoes formed by harmonic alignment or resonance.

Indicators:

• matching intervals
• harmonic ladder alignment
• resonance peaks

Stability: moderate–high
Typical Family: F2
Typical ESI: 2–3
Drift Link: D1–D2
Recursion Link: R1–R2

🔷 3. Signature C — Substrate Echo Signature#

Symbolic ↔ Cognitive ↔ Harmonic ↔ Social Migration#

Definition:
Echoes formed by cross‑substrate recurrence.

Indicators:

• substrate migration
• semantic reinterpretation
• cross‑layer resonance

Stability: mixed
Typical Family: F3
Typical ESI: 2–3
Drift Link: D2–D3
Recursion Link: R2–R3

🔷 4. Signature D — Recursion Echo Signature#

Ladder → Cycle → Map → Atlas Patterns#

Definition:
Echoes formed by recursion activation or mode shifts.

Indicators:

• recursion pattern repetition
• mode transitions
• structural lineage across recursion layers

Stability: unstable
Typical Family: F4
Typical ESI: 3–4
Drift Link: D2–D3
Recursion Link: R2–R4

🔷 5. Signature E — Drift‑Shadow Echo Signature#

Echoes Formed by Drift Residues#

Definition:
Echoes created by drift artifacts or residues.

Indicators:

• inconsistent interval alignment
• elevated mutation rate
• semantic duplication
• operator inversion echoes

Stability: low
Typical Family: F5
Typical ESI: 3–4
Drift Link: D1–D4
Recursion Link: R3–R4

🔷 6. Signature F — Atlas Echo Signature#

High‑Altitude Structural Resonance#

Definition:
Echoes formed at the atlas layer.

Indicators:

• cross‑module resonance
• high‑altitude conceptual lineage
• atlas‑level recursion

Stability: extreme (stabilizing or destabilizing)
Typical Family: F6
Typical ESI: 4
Drift Link: D4
Recursion Link: R4

🔷 7. Echo Signature Matrix#

+----------------------+-----------+-----------+-----------+-----------+--------+
| Signature            | Stability | Substrate | Drift     | Recursion | Family |
+----------------------+-----------+-----------+-----------+-----------+--------+
| A Structural         | High      | S,C       | D0–D1     | R1        | F1     |
| B Harmonic           | Med-High  | H         | D1–D2     | R1–R2     | F2     |
| C Substrate          | Mixed     | S,C,H,So  | D2–D3     | R2–R3     | F3     |
| D Recursion          | Low       | H,So,A    | D2–D3     | R2–R4     | F4     |
| E Drift-Shadow       | Low       | S,H,A     | D1–D4     | R3–R4     | F5     |
| F Atlas              | Extreme   | S,C,H,So,A| D4        | R4        | F6     |
+----------------------+-----------+-----------+-----------+-----------+--------+

🔷 8. Signature Escalation Path#

Echo signatures escalate in a predictable RTT‑native progression:

A → B → C → D → E → F
structural → harmonic → substrate → recursion → drift-shadow → atlas

This path predicts:

• echo‑pressure
• drift escalation
• recursion forcing
• atlas resonance
