Closed **2026-05-20** on superrepo [`f57377a`](https://github.com/Cyber-Nomad-Collective/beskid/commit/f57377a) (v0.2 delivery tip). Spawn/fiber runtime surfaces, channel primitives, vendored **abfall** GC heap integration, runtime module alignment, and platform-spec GC/interop alignment. Workstreams: `codegen-runtime`. **9** catalog tasks anchor this deliverable (`milestoneId: v02-concurrency-runtime`). ## Provenance - [`12ee673`](https://github.com/Cyber-Nomad-Collective/compiler/commit/12ee673) (`compiler`) — feat: spawn/fiber runtime, channels, and split System I/O surfaces - [`3a9a083`](https://github.com/Cyber-Nomad-Collective/beskid_standard/commit/3a9a083) (`corelib`) — corelib: syscall surfaces, docs, and tests - [`0ded628`](https://github.com/Cyber-Nomad-Collective/compiler/commit/0ded628) (`compiler`) — compiler: runtime/ABI updates, doc command, corelib submodule bump, tests - [`6ecd493`](https://github.com/Cyber-Nomad-Collective/compiler/commit/6ecd493) (`compiler`) — feat(runtime): vendored abfall GC and Beskid heap integration - [`6db12d2`](https://github.com/Cyber-Nomad-Collective/beskid_standard/commit/6db12d2) (`corelib`) — fix(ci): run corelib prelude lowering tests on an 8 MiB stack - [`ee3d83d`](https://github.com/Cyber-Nomad-Collective/beskid_standard/commit/ee3d83d) (`corelib`) — feat(corelib): expand syscall coverage and stdlib tests - [`2ddddb3`](https://github.com/Cyber-Nomad-Collective/beskid_standard/commit/2ddddb3) (`corelib`) — test(corelib): extend concurrency tests and align concurrency packages - [`4e5bfca`](https://github.com/Cyber-Nomad-Collective/compiler/commit/4e5bfca) (`compiler`) — docs(abfall): document Beskid vendoring and upstream repository link - *…and 1 more seed tasks with provenance commits.* ## Catalog scope - **Delivery version:** v0.2 (Analysis, packages, and platform spec) - **Deliverable:** `v02-concurrency-runtime` — Fibers, channels, and GC runtime ## Relation Groups the v0.2 seed tasks linked via `milestoneId` for **Fibers, channels, and GC runtime**.
