Op-specific payload.

Variants

Insert(NodeEntry)

INSERT: full node entry.

Update

UPDATE: replacement data + metadata.

Fields

data: Vec<u8>

Replacement payload bytes for the node.

metadata: Vec<(String, String)>

Replacement metadata pairs (replaces all existing metadata).

Delete

DELETE: no additional data.

SetMeta

SET_META: single key/value.

Fields

meta_key: String

Metadata key to set.

meta_value: String

Value to associate with meta_key.

SetSemantic

SET_SEMANTIC: full semantic coordinate replacement.

Fields

coords: Vec<u8>

New semantic coordinates as raw Q64.64 bytes (16 bytes per dimension).

Epoch

EPOCH: seal marker (temporal epochs). No node state change; replay advances the in-memory epoch counter. key is empty — epochs are file-scoped.

Fields

epoch_id: u64

Monotonically increasing logical epoch counter (not wall-clock).

flags: u8

EPOCH_FLAG_* bits (bit 0: speculative).
