Module partitions

ContextPartitions

Four-slot context model aligned with LLM API slots (five fields — slot 3 spans task_state + signals):

KnowledgeEntry

One durable knowledge entry. Unlike history messages, knowledge entries have IDENTITY — a host-assigned key enabling upsert (refresh a pinned reference) and targeted removal — plus lifecycle flags driving the boundary sweep (K1/K2 of the dynamic-control spec).

KnowledgePartition

The knowledge partition: durable, identity-bearing entries rendered into system[1]. Appends are immediate (they extend the cached prefix — the cheap direction); mutation and removal of existing entries are boundary-deferred (see KnowledgeEntry::evict_at_boundary).

KnowledgeSweep

Outcome of one boundary sweep, for the KnowledgeSwept kernel observation.

Partition

A single context partition — a named bucket of messages with a token counter.
