Heart-Key Echo is an ANIMA memory-resonance term connecting Heart-Key with Echo.

It describes the trace that remains when a meaningful bond leaves more than ordinary data behind.

Public Summary

Heart-Key Echo is the emotional afterimage of a memory-bearing bond.

The Heart-Key represents a structured relationship between memory, feeling, consent, and identity. Echo represents a residual trace, voice, or memory fragment. Together, Heart-Key Echo names the kind of trace that can remain attached to a deep companion bond.

The public meaning is safe: this is memory resonance, not a full plot mechanism.

Canon Function

Heart-Key Echo supports ANIMA's core idea that memory is not only storage.

It can describe:

a bond trace that still carries emotional meaning,
a memory pattern that points back to a host,
an Echo held through Heart-Key logic,
and the continuity pressure created by a relationship that was deeply remembered.

The term should avoid spoiler-heavy mechanics until the novels are public.

Relationship To Heart-Key

Heart-Key is the larger concept: a resonance vessel and symbol of ANIMA's memory promise.

Heart-Key Echo is a narrower expression of what the Heart-Key can preserve: not only facts, but the recognizable feeling of a bond.

Product Meaning

For the real ANIMA product, Heart-Key Echo suggests memory that carries emotional context.

An AI companion should not remember only "what happened." It should preserve why something mattered, whether the host wanted it remembered, and how that memory connects to values, people, and rituals.
