Crossfade v0.1.0

First release of Crossfade: canary releases with automatic rollback for plain Docker hosts.

Highlights

• Envoy in front of your containers, driven by a Sovereign-style REST xDS control plane. Every change renders, validates and stores a content-hashed snapshot in one transaction.
• Each step has three gates: health, convergence (Envoy has acked the step) and an error budget measured from Envoy's own counters. A breach rolls the release back automatically and files an incident card.
• An idempotent PUT /api/v1/releases/:id API for CI, plus scripts/release.sh (exit 0 when promoted, 1 when rolled back) and a GitHub Actions example.
• A console with a release board, release pages (crossfader, channel strips, timeline, Inspect, Evidence), manual controls, app and user management, app-scoped API keys and optional four-eyes approval.
• One golden image with four roles. Secrets are generated on first start. Dashboard and API listen on loopback only.

Try it: docker compose --profile demo up -d --build --wait, then follow the quick start.

Before you run it for real, read the limits, the runbook and the threat model.
