Intuition

Build the mental picture first so the rest of the page has something to attach to.

Section prompt

An audit trail proves what happened. A retention rule decides what is allowed to remain.

That distinction matters because adaptive-learning memory can keep growing. Every release can leave behind learner-impact notes, support receipts, teacher overrides, event histories, and version records. Some memory remains valuable. Some should be masked. Some is too old, too detailed, too risky, or tied to a deletion duty.

A strong retention rule separates seven routes:

retain a packet when it is valuable, bounded, and still inside its retention window,
redact sensitive fields before the packet remains searchable,
expire old memory while keeping a minimal tombstone,
minimize unnecessary detail to the smallest useful record,
quarantine conflicted or risky packets,
hold export until transfer approvals are settled,
and delete records when deletion is required.

The habit is simple: do not let reconstructable memory become permanent memory by default.

Math

Translate the story into symbols, assumptions, and a derivation you can inspect.

Section prompt

Equation 1 $T(m)=(v, a, p, n, r, x, d),$ Equation 2 $q_j(m)=\frac{\text{retention checks passed for dimension } j}{\text{retention checks required for dimension } j}.$

Let a memory packet $m$ have seven retention dimensions:

T(m)=(v, a, p, n, r, x, d),

where $v$ is reuse value, $a$ is retention age, $p$ is learner-record exposure, $n$ is minimization fit, $r$ is unresolved risk or conflict, $x$ is export obligation status, and $d$ is deletion duty.

For each dimension, define:

q_j(m)=\frac{\text{retention checks passed for dimension } j}{\text{retention checks required for dimension } j}.

A compact retainability score is:

K(m)=w_vq_v+w_aq_a+w_pq_p+w_nq_n+w_rq_r+w_xq_x+w_dq_d.

The route still follows hard constraints:

\operatorname{retain}(m)= \begin{cases} \text{delete packet}, & \text{if a valid deletion duty applies},\\ \text{export hold}, & \text{if external-transfer approval or consent is missing},\\ \text{quarantine packet}, & \text{if conflict, incident, or policy risk is unresolved},\\ \text{redact sensitive fields}, & \text{if learner-record exposure remains},\\ \text{expire memory}, & \text{if the retention window is closed and reuse value is low},\\ \text{minimize record}, & \text{if the packet keeps more detail than future accountability requires},\\ \text{retain packet}, & \text{if value, age, privacy, minimization, risk, export, and deletion checks pass}. \end{cases}

This keeps memory useful without treating usefulness as permission to keep everything.

Code

Keep the implementation aligned with the notation so the algorithm is legible.

packet = {
    "reuse_value": 0.91,
    "age_days": 18,
    "retention_limit_days": 45,
    "pii_exposed": False,
    "minimum_fields_only": True,
    "conflict_open": False,
    "export_approval_missing": False,
    "deletion_required": False,
}

if packet["deletion_required"]:
    route = "delete packet"
elif packet["export_approval_missing"]:
    route = "export hold"
elif packet["conflict_open"]:
    route = "quarantine packet"
elif packet["pii_exposed"]:
    route = "redact sensitive fields"
elif packet["age_days"] > packet["retention_limit_days"] and packet["reuse_value"] < 0.4:
    route = "expire memory"
elif not packet["minimum_fields_only"]:
    route = "minimize record"
else:
    route = "retain packet"

print(route)

Real systems should attach retention windows, deletion requests, learner-record boundaries, export/transfer obligations, minimization checks, quarantine reasons, and owner review to every searchable memory packet.

Interactive Demo

Use direct manipulation to connect the explanation to a moving system.

Section prompt

Use the Memory Retention Rules lab to predict what should happen before a memory packet remains searchable or reusable:

Ready retain: decide when memory can remain as-is.
Sensitive fields: decide when fields must be redacted.
Expired packet: decide when old memory should expire.
Too much detail: decide when records should be minimized.
Conflict risk: decide when memory should be quarantined.
Export blocked: decide when export hold is required.
Delete duty: decide when the packet must be deleted.

Before reveal, exact value, privacy, age, minimization, conflict, export, and deletion proof stays locked. After reveal, inspect the retention route that controls whether memory can remain.
