v0.9.1

Added

• astrid:process@1.1.0 host interface. Additive successor to the frozen astrid:process@1.0.0, carrying the host-verified, read-only per-spawn file-injection surface (the file-injection record, the injection-placement variant, and the spawn-request.file-injections field). The kernel serves both versions off one implementation; capsules opt into injection by importing @1.1.0, while @1.0.0 behaves as spawn-with-no-injections. Refs #1107, wit#19, #881.

Fixed

• Shipped capsules that import astrid:process@1.0.0 instantiate again — no rebuild required. The per-spawn file-injection extension originally landed in-place on the frozen astrid:process@1.0.0 WIT (wit#15), changing the shape of spawn-request. The component-model linker matches host imports structurally by package version, so every capsule compiled against the published pre-extension contract (all shipped capsules, built on astrid-sys 0.7.x) failed to instantiate on 0.9.0 with component imports instance astrid:process/host@1.0.0, but a matching implementation was not found in the linker — the sage supervisor could not astrid init and astrid-capsule-shell v0.2.0 failed to load. The kernel now restores @1.0.0 to its published shape and serves it alongside the additive @1.1.0 (dual-version host, mirroring the astrid:http@1.0.0/@1.1.0 precedent), so existing capsules load unchanged. Refs #1107, wit#19, #881, #890.

Install

From source (requires Rust 1.95+):

cargo install astrid

Pre-built binaries:
Download the archive for your platform, extract, and add to PATH:

tar xzf astrid-*-$(uname -m)-*.tar.gz
sudo mv astrid-*/astrid astrid-*/astrid-daemon astrid-*/astrid-build astrid-*/astrid-emit /usr/local/bin/

Then run astrid init to set up capsules.
