Struct LinkVerifyRecord 

pub struct LinkVerifyRecord {
    pub source_id: String,
    pub target_id: String,
    pub relation: String,
    pub signature: Option<Vec<u8>>,
    pub observed_by: Option<String>,
    pub valid_from: Option<String>,
    pub valid_until: Option<String>,
    pub attest_level: Option<String>,
}

v0.7 H4 — full row-projection used by the memory_verify MCP tool.

get_links (above) was deliberately scoped to the four columns the graph-traversal callers care about; H4 needs the signed bundle — the raw signature blob, the agent_id that signed (observed_by), and the temporal-validity columns the signature commits to. Splitting it from get_links keeps the existing read path’s wire shape unchanged (and its column-count tested by callers).

Returns Ok(None) when the row is absent so the caller can shape a “not found” response instead of bubbling up a generic SQL error.

Fields

source_id: String

target_id: String

relation: String

signature: Option<Vec<u8>>

observed_by: Option<String>

valid_from: Option<String>

valid_until: Option<String>

attest_level: Option<String>

Raw column value as stored by H2/H3 ("unsigned", "self_signed", "peer_attested", or rarely NULL for very old rows that pre-date the H2 attest_level column). H4’s MCP handler normalises a NULL to the Unsigned enum variant.
