Ingestion is a partial port, so a graph this backend writes has had only
some of the pipeline applied. Rather than have a reader infer which from
a build version, the build writes it down: `GraphMeta.transforms` names
every transform id applied, projection-time denormalizations included,
and the parity consumer computes the complement and runs only that.
The ids cross a language boundary as data, so they are kebab-case
strings rather than keywords and must stay byte-identical to the
consumer's own list.
This stays off `graph-backend`. Nothing in this repository reads the
column, and an unread column is weight a reviewer is right to question.

A projected graph is a cache of one file at one revision, built by one
schema, and nothing in it said so. `GraphMeta` records the file, the
revision, the schema version and the producer, and is written last, so
its presence also marks the build complete and its contents say whether
a cached database is still worth opening.
- `graph/meta.clj`: the `GraphMeta` table and its writer.
- `graph/schema/contract.clj`: one place that maps a Penpot key to its
graph column. The rule is snake_case of the key; every exception, be
it a rename, a drop or a type override, is recorded there with its
reason, so a divergence is a diff to review rather than a silent
rename.
- `graph/project/document.clj`: `page-id` and the inherited
`component-id` are written during the tree walk, which already knows
both, rather than by a post-ingest statement. `graph/sync.clj` does
the same on the incremental path, so a live-synced graph matches a
rebuild.
- `graph/project/transforms.clj`: a registry, so adding a derived-link
pass is one entry. Adds `RefersTo` (from `shape-ref`) and
`FillsSwapSlot` (from `swap-slot-*` entries in `touched`, then
stripped as `ctk/normal-touched-groups` does).
- `graph/debug.clj`, `graph/stats.clj`: enumerate relationship tables
from the catalog instead of naming them, so the console's graph view
and the ingest counts pick up new edge types without being told.
- `graph/debug.clj`, `http/debug.clj`: `graph-export` gains
`source=session`, which snapshots the live in-memory console graph
through EXPORT/IMPORT DATABASE. Live sync moves that graph away from a
fresh projection, and taking it away to query elsewhere is the point
of asking for it.
