v0.2.0 — Blue Steel (first cut)

CARB/IDE2 is a browser-based collaborative development environment. Each workspace runs as its own pod in a Kubernetes (k3d) cluster, with a control plane and operator bringing workspaces up on demand. This is the first tagged cut — early but usable end to end. "Blue Steel" is the name of the current UI pass.

What's in it

• Per-workspace pods — a control plane + operator spin up an isolated pod per workspace.
• In-database filesystem (DBFS) — files live in Postgres and flush/watch to disk; edits persist continuously (there is no separate "save" step).
• Code editing — Monaco editor wired to the live DBFS.
• Shared terminals — PTY sessions broadcast to everyone connected to the workspace.
• Agent chat with tool calls — an in-workspace AI agent that can read and modify the project through tools, with a grouped tool-call UI.
• Project chat — per-project channels with presence and avatars.
• Git import — clone a repository into a new project.
• Deployment — runs on k3d via deploy.rb (scoped rollouts, optional shell-image skip) plus a quickstart/install path.

Requirements

• Linux host with a k3d/Kubernetes cluster and PTY support.
• See INSTALL.md / quickstart.sh to bring up a local cluster.

Known limitations

• Multi-account collaboration is rough — presence/typing can misbehave when the same account is connected twice.
• Some connection/throughput indicators are not yet accurate.
• Imported project files may land owned by root, which can block edits until permissions are fixed.

This is a 0.x cut: expect rough edges and breaking changes between releases.

v0.2.0 — Blue Steel (preview 1)

First coherent cross-repo preview release of CARB/IDE2, codename Blue Steel.

Validated by a clean fresh-box k3d deploy on Ubuntu 24.04 (separate machine, deployed from local checkouts).

Pinned components

Highlights since the ad-hoc v0.1.x tags

• One-shot deploy/redeploy orchestrator (scripts/deploy.rb): cluster + infra bring-up, image build/import, CRD, control-plane chart, mkcert TLS, verify. Idempotent; quiet build output (only surfaces on failure); all-platform root-CA trust instructions printed at the end.
• Fresh-box provisioning (scripts/setmeup.sh) for Ubuntu 24.04.
• New meta INSTALL.md: clean host → running stack, including per-platform (Windows/Linux/macOS/Firefox) root-CA trust.
• Persistent worker logging to /srv/projects/.carbide/worker.log (heartbeat + signal/exit tracing) so the next workspace-pod failure is debuggable.
• UI polish: editor pane no longer double-renders the filename header; CSS consolidated onto @theme tokens.
• Agent configuration is now a first-class UI pane (previously only reachable via rails console in the pod).

Known caveats

• Preview: not yet merged to main on every repo (tags ride current branches).
• Default ingress ports remain 8080/8443; set HTTPS_PORT=443 HTTP_PORT=80 for a standard deploy.
• System prompts are not yet sanitized in any future chat export (#33).
