This opens the PR for the existing refactor/metadata-only branch (8108764, Tristan's commit from 2026-10-02). It doesn't change the branch.

Pulsar-Native has pinned crates/third-party/pbgc to this commit since then. Because the commit isn't on PBGC's main, it is the one entry in Pulsar-Native's .github/submodule-pin-exceptions.txt: "PBGC branch refactor/metadata-only; no upstream PR yet". Once this merges, Pulsar-Native can pin the merge commit and drop that exception.

What the branch does, from its commit message: it removes the bytecode compiler, the VM and the graph-to-Rust backend, leaving the pulsar_std node catalogue. Blueprint graphs now compile to script modules (blueprint_compiler), and the Rust export is generated from those (pulsar_script_codegen).

It merges cleanly with main, and the merged tree is identical to the branch tip. Main's only commit not on the branch is the merge of #11, whose files the branch removes.

build fails in tests/metadata.rs. flow_intrinsics_keep_their_exec_pins expects delay to have the exec output Completed and finds none.

The cause is the pulsar_std pin. This repository's CI builds against pulsar_std at Pulsar-Native 38bbbd93. At that revision delay was still a blocking thread::sleep with no exec pins; Completed arrived later, in Pulsar-Native e9776a0c1. Inside Pulsar-Native the test passes, because there PBGC uses the workspace's current pulsar_std.

Moving the pin to current Pulsar-Native main isn't enough on its own; I tried it:

• cargo update -p libc is needed to resolve.
• After that, pulsar_script_vm fails to compile because two copies of pulsar_reflection end up in the graph. One comes from Pulsar-Native's submodule, the other from SceneDB's Pulsar-Reflection pin.

So a standalone build would also need [patch] entries that resolve both copies to one Pulsar-Reflection revision, the way Pulsar-Native's root manifest does. The alternative is to build this crate inside a Pulsar-Native checkout, as Plugin_Shaders' CI does.

I haven't pushed either to this branch, since the branch is Tristan's. Say which approach you prefer and I'll make the change.

I'm closing this without merging. PBGC is no longer needed.

After this branch, PBGC was only the pulsar_std → Graphy metadata converter, and the Blueprint editor was its only user. That converter now lives in the plugin (Far-Beyond-Pulsar/Plugin_Blueprints#36), and Pulsar-Native removes the PBGC submodule in Far-Beyond-Pulsar/Pulsar-Native#1387.

That also takes care of the failing build here. The plugin builds against the current pulsar_std, where delay has its Completed exec output, and the moved test passes.

The refactor/metadata-only branch is left as it was. Once #1387 merges, the repository could be archived if you want.
