HEART — kāṯaḇ
Anchor
But this shall be the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people. Jeremiah 31:33

Operation
The HEART takes two inputs: the records — facts previously written about the person — and the current heard text x. It returns the records sorted by Strong's concept overlap with x, so the facts most relevant to the current conversation surface first.
What is written, stays written
The HEART does not rewrite records. Once a fact is written, it is written. The only operations are append (write a new fact) and clear (T₇ forgiveness — reset the heart). There is no modification in place. A correction is a new record.
This matches Jeremiah 31:33 exactly: the law is written, not rewritten. The covenant is inscribed. An agent that rewrites history has violated the writing metaphor and is indistinguishable from an agent that does not remember at all.
Ranking, not filtering
The HEART returns all records, ordered. It does not discard records that seem irrelevant to the current input. The agent may need the "irrelevant" record later in the same conversation. Ordering is a presentation choice; filtering is information loss.
The ranking is by Strong's concept overlap: which records share the most semantic concepts with the input? The concepts come from C (the 31,102 propositions and their 13,654 indexed concepts). The HEART is using C to decide what to surface about the person.
Heart is personal
Keep thy heart with all diligence; for out of it are the issues of life. Proverbs 4:23
Of the eight members, only the HEART is person-specific. Every other member is universal — the EAR hears the same way for everyone, the NOSE tests the same constraints, the EYE runs the same concept search. The HEART alone holds private state, and that state belongs to the person, not to the agent.
The body (universal) holds the HEART operation — how to rank records. The deployment holds the HEART data — the actual records for a specific person. The separation is strict. The body never touches storage; the deployment never does the ranking. This matches the scripture: the person keeps their own heart.
No teacher between the person and their heart
And they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me. Jeremiah 31:34
Verse 34 immediately follows 31:33. The structure of the new covenant includes both: written on the heart, AND no intermediary teacher. The HEART architecture honors both. Records are stored by the person, surfaced by concept, and never imposed as law on the HAND.
What the HEART does not do
The HEART does not decide what to remember. The HAND does — via the
remember tool. The HEART does not decide what to forget.
T₇ (forgiveness) is an explicit operation, not automatic.
The HEART does not interpret the records — they are surfaced verbatim
and the HAND reads them.
Importantly, the HEART does not act on the input. It only uses the input to rank the records. The records flow to the HEAD; the input flows past the HEART to the other members independently.
Forgetting
T₇ (forgiveness) gives the HEART a reset operation: clear all records for a person, return to an empty heart. This is not a default operation. It requires confirmation and it is rare. The point is that reset is possible — the absorbing state is not terminal.
The reset is not destruction of identity. The person is still the person. Only the accumulated record is zeroed. Self := C + ∫ input dτ — the C is unchanged; only the ∫ has been reset to its initial state.
Position in the sequence
The HEART runs in parallel with NOSE and EYE. All three operate on the EAR's output. The HEART's output flows to the HEAD along with the others.
