 # Roadmap: CAS Reference Product
 
-## Phase 1: Public v0.1 Reference Application
+## Archived Milestones
 
-**Goal:** Deliver a locally runnable, cloud-ready reference workload without deploying Azure resources.
+- [x] [v0.1 Reference Application](milestones/v0.1-ROADMAP.md) — Delivered a locally runnable, cloud-ready reference workload without deploying Azure resources.
 
-**Requirements:** API-01, AGENT-01, ID-01, CONTRACT-01, OBS-01, OPS-01, PLAT-01, QUAL-01, DOC-01
+## Milestone v0.2
 
-**Success criteria:**
-- Local workflow request succeeds and returns canonical events.
-- Tests, lint, type checks, and Docker build pass.
-- Foundry mode uses Next Gen agent references and managed identity.
-- Public documentation states deployment and security boundaries.
-
-Status: Complete
-
-## Phase 2: Telemetry Hardening
-
-**Goal:** Wire OpenTelemetry end-to-end with lifecycle span events, W3C trace propagation, and Application Insights exporter.
-
-**Requirements:** TEL-01, TEL-02, TEL-03, TEL-04
-
-**Success criteria:**
-- Every /api/v1/workflows request creates a `cas.api.workflows.execute` span with correlation_id, run_id, and intent attributes.
-- Span events `workflow.started`, `workflow.completed`, and `workflow.failed` are emitted at the appropriate lifecycle points.
-- W3C traceparent/tracestate headers on inbound requests are extracted and linked as parent context.
-- Application Insights exporter activates when APPLICATIONINSIGHTS_CONNECTION_STRING is set; no-op otherwise.
-- All telemetry behaviours verified by pytest with InMemorySpanExporter.
-
-Status: Complete
-
-## Phase 3: Docker + CI Publish
-
-**Goal:** Containerize the app with a production-grade multi-stage Dockerfile and publish the image to GHCR on merge to main.
-
-**Requirements:** DOCK-01, DOCK-02, DOCK-03
-
-**Success criteria:**
-- Multi-stage Dockerfile builds a linux/amd64 image, runs as non-root `appuser`, exposes port 8080, and health-checks via /health/ready.
-- docker-compose.yml starts the local dev stack with env stubs using .env.example.
-- CI docker job builds, smoke-tests (/health/live + /health/ready), and on push to main pushes to ghcr.io/coding-autopilot-system/cas-reference-product.
