`manifest.json` carries no column-to-column edges, which is why decision 14 recorded column lineage as unavailable. The edges live in a different artifact: `dbt compile --static-analysis strict --write-index` writes `target/index/`, whose `dbt.column_lineage.parquet` holds them and whose `dbt.node_columns.parquet` holds every column of every node, typed and ordered rather than only the ones an author documented. Strict analysis rejects SQL the default accepts, so this is a separate compile with its own `--target-path`, opt-in per project via `column_lineage: true`, and best-effort throughout: a project it cannot analyze keeps exactly the graph it had, with the engine's own diagnostics in the job log. Storage mirrors `dbt_edge`: `dbt_column_edge` keyed by (path, version, job) with the same composite FK to `script` and the same sweeps. The typed column list lands in `dbt_node.column_schema`, beside `columns` rather than merged into it, so `columns` stays what the author declared.
