Roadmap

Xtrape Capsule is shipped in incremental milestones. We avoid promising specific dates; status labels reflect the current intent.

Status	Meaning
Current	Available today or being validated in Public Review
Planned	Committed for a near-term milestone
Future	On the roadmap; not yet committed
Experimental	Planned as a trial; shape may change

Current status

v0.4 Capsule Bus Experimental is the active experimental milestone on the v0.4 branch. It adds CE's built-in SQLite-backed in-process event-to-command routing, disabled by default, for controlled trials. The pinned GHCR image (ghcr.io/xtrape-com/xtrape-capsule-ce:<semver>) and source-build Docker Compose path are both supported deployment options. Capsule Bus is not recommended for business-critical HA production.

Roadmap Snapshot

• v0.1 Public Review Foundation — CE, Agent SDK, Contracts, Demo, and public docs are validated end-to-end.
• v0.2 Developer Experience & Runtime Maturity — Docker/release maturity, SDK reliability, demo polish, command/action/audit improvements.
• v0.3 Capsule Events and Capability Metadata — capability, event, and permission metadata foundations.
• v0.4 Capsule Bus Experimental — governed event-to-command routing for controlled service coordination.
• v0.5 Capsule Catalog — read-first catalog for discoverable Capsule Packages.
• v0.6 Capsule Registry — machine-readable package index, versions, compatibility, and trust metadata.
• v0.7 Private Capsule Marketplace — internal/private marketplace workflows for package approval, install requests, and governance.
• v1.0 CE Stable and Ecosystem Foundation — stable CE deployment, stable contracts/SDK, upgrade path, and ecosystem baseline.

Catalog, Registry, Marketplace, and AI-assisted governance remain future roadmap items. Capsule Bus is experimental in v0.4 and should not be presented as stable.

v0.1 — Public Review Foundation

Status: Current

Scope

• Opstage backend (Fastify + SQLite via Prisma)
• React 18 + Ant Design admin console
• Node Embedded Agent SDK (@xtrape/capsule-agent-node)
• Capsule Management Contract v0.1
• Registration tokens and agent tokens, hash-only storage
• Inventory: Agents, Capsule Services, Audit Events, Commands
• Health, configs, actions, command lifecycle
• Source-build Docker Compose deployment
• SQLite backup download, audit export
• RBAC: owner / operator / viewer

Not included

• HA / clustering
• SSO / SCIM
• Stable v0.1.0 GHCR image as the primary path before the Public Preview cut
• Cross-language Agent SDKs
• Catalog, Registry, Marketplace, Capsule Bus, or AI-assisted governance implementation

v0.2 — Developer Experience & Runtime Maturity

Status: Planned

Scope

• Docker and release maturity, including the pinned Public Preview image path
• SDK reliability and troubleshooting improvements
• Demo polish for common integration flows
• Command, action, and audit improvements informed by Public Review feedback
• Better operational diagnostics and recovery guidance

Not included

• HA / clustering
• Cross-language Agents
• Catalog, Registry, Marketplace, or Capsule Bus implementation

v0.3 — Capsule Events and Capability Metadata

Status: Future

Scope

• Capability metadata foundations
• Event metadata foundations
• Permission metadata foundations
• Compatibility guidance for services and SDKs that report these fields

Not included

• Governed event routing or marketplace workflows

v0.4 — Capsule Bus Experimental

Status: Experimental

Scope

• CE built-in SQLite-backed in-process event-to-command routing (single-node, disabled by default)
• Experimental event envelope and route-rule contracts
• CE event ingestion, route storage, diagnostics, and audit records
• Event-to-command routing from eventType plus optional sourceServiceCode to target service/action commands
• OpHub thin-forwarding from optional local adapter GET /capsule/bus/events
• Embedded Agent publishBusEvent() hook for controlled trials
• Demo adapter endpoint for a minimal event example
• Safety guardrails: OPSTAGE_CAPSULE_BUS_ENABLED=false by default, per-agent rate limit (OPSTAGE_CAPSULE_BUS_INGEST_PER_MIN), max-depth guard (BUS_DEPTH_EXCEEDED), DRY_RUN route state

Not included

• No standalone Bus Server in v0.4
• No external broker provider (NATS / RabbitMQ / Redis Streams / Kafka)
• No fan-out / maxCommandsPerEvent — one matched route produces at most one command
• No HA / clustering / distributed bus
• No stable API guarantee before v1.0
• No workflow engine, service mesh, or broker replacement semantics
• No public marketplace or registry workflows

v0.5 — Capsule Catalog

Status: Future

Scope

• Read-first catalog for discoverable Capsule Packages
• Package metadata presentation
• Documentation and discovery flows

Not included

• Machine-readable registry guarantees
• Install request and approval workflows

v0.6 — Capsule Registry

Status: Future

Scope

• Machine-readable package index
• Versions, compatibility, and trust metadata
• Foundations for automated compatibility checks

Not included

• Marketplace governance workflows

v0.7 — Private Capsule Marketplace

Status: Future

Scope

• Internal/private marketplace workflows
• Package approval and install requests
• Governance hooks for private ecosystems

Not included

• Public SaaS marketplace commitments

v1.0 — CE Stable and Ecosystem Foundation

Status: Future

Scope

• Stable CE deployment and documented upgrade path
• Stable contracts and SDK baseline
• Migration tooling and compatibility policy
• Ecosystem baseline across CE, SDKs, Contracts, Demo, and docs

Not included

• Multi-node CE; HA remains an Enterprise Edition concern

Enterprise Edition and Cloud

Status: Future

Enterprise Edition and Cloud remain future tracks for organization RBAC, SSO, SCIM, HA/clustered deployment, centralized logs, tenant isolation, advanced audit and approval workflows, hosted operations, and region-pinned data. They should guide extension-point design, but they are not part of the current Public Review build.

INFO

Roadmap items marked Future or Experimental may shift in scope or order based on community usage and feedback. If you're considering adopting future Enterprise Edition or Cloud capabilities, please open a discussion on xtrape-capsule-ce.
