Struct TrackingRow 

pub struct TrackingRow {
    pub id: String,
    pub onto: String,
    pub db_state: Option<String>,
    pub schema_state: Option<String>,
    pub applied: bool,
}

One row of _pylon."Migrations" — covers both apply’s own tracking logic (id/onto/applied, for computing the applied tip) and migration create’s diff-baseline lookup (db_state and schema_state, the JSON snapshots recorded on the tip row by apply). filename isn’t read — nothing in this codebase actually consults it once a row exists.

Fields

id: String

onto: String

db_state: Option<String>

The db_state JSON snapshot (catalog/DDL-visible shape only), pre-rendered as text (db_state::text) rather than decoded as jsonb — callers (db_state_from_json) want the raw JSON string to re-parse, not an already-decoded value tree.

schema_state: Option<String>

The full SchemaDescriptor JSON as of this migration (everything db_state has, plus schema semantics with zero DDL footprint — readonly, rewrites, Channels, …). migration create diffs against this (the tip row’s own recorded state), not against _pylon."Schema", for the same reason db_state already does: watch may have pushed ad hoc changes straight to the live database without ever going through migration create, and those must still show up as a pending change here rather than silently being treated as already-baselined. Pre-rendered as text for the same reason as db_state — re-parse via SchemaDescriptor.from_json.

applied: bool
