# Armature — Roadmap

## Current: v0.9.x — Workflow Redesign + Multi-Surface Packages

Self-hosted extensible platform kernel. Auth, identity, packages, Starlark
sandbox, storage, realtime, and ops are kernel primitives. Everything else
is an extension.

**Kernel capabilities:** Auth (builtin/mTLS/OIDC) · Users/teams/groups/RBAC ·
Surfaces/extensions/libraries/workflows · Starlark sandbox (capability-gated) ·
Object storage (PVC/S3) + ext_data tables · WebSocket hub + realtime pub/sub ·
Audit log · Notifications · Scheduled tasks · Cluster registry + HA ·
Extension composability (slots/contributes/cross-package calls)

## Planned

### v0.9.x — Multi-Surface Packages + Workflow Redesign

**v0.9.0 — Multi-Surface Packages** *(completed)*

Packages declare a `surfaces` array with per-path access controls,
titles, and layouts. Unified route tree dispatches between surface
rendering and ext API calls. `sw.navigate()` for client-side sub-path
routing. Design doc: `docs/DESIGN-multi-surface.md`.

**v0.9.1 — Server-Side Sub-Path Routing** *(completed)*

Consolidated root and catch-all route handlers into a unified dispatcher.
Added `aggregateAccess()` for early auth short-circuit on all-authenticated
packages. SDK seeds initial history state for back-button resilience.
8 handler integration tests + 5 aggregateAccess unit tests.

**v0.9.2 — Starlark Converter Consolidation + Snapshot Cleanup** *(completed)*

Consolidated duplicate Go↔Starlark converters into `sandbox/convert.go`
(4 exported functions) and snapshot parsers into `models/snapshot.go`.
Standardized on wrapped snapshot format. ~350 lines of duplication removed.
Design doc: `docs/DESIGN-workflow-redesign.md`.

**v0.9.3 — Team User Roles** *(completed)*

Many-to-many `team_user_roles` table. `RequireRole()` middleware.
Manifest `requires_roles` field (advisory). Starlark `teams` module
with `get_member_roles()` and `has_role()`. Team-admin UI with role
badge chips and assignment dropdown. 10 new tests.

**v0.9.4 — Package Adoption + Roles**

`scope: adoptable` manifest field. When a team adopts an adoptable
package, the package's `requires_roles` auto-populate into the team's
role slots. Replaces `AdoptTeamWorkflow` clone mechanism.

**v0.9.5 — Typed Forms → SDK Primitive**

Extract `TypedFormTemplate`, `FormField`, `FormFieldset`, etc. from
`models/workflow.go` into a `forms` package. FE SDK: `sw.forms.render()`
and `sw.forms.validate()`. Starlark: `forms.validate()`. Any package
can declare forms, not just workflow stages.

**v0.9.6 — Deprecate `stage_type`, Collapse `stage_mode`**

`stage_type` (simple/dynamic/automated) is redundant with `starlark_hook`
presence. Remove from new manifests, keep parsing for backward compat.
Collapse `stage_mode` from 4 to 3 values: form / delegated / automated.

**v0.9.7 — Full Read/Write Workflow Starlark Module**

Add `workflow.start()`, `workflow.advance()`, `workflow.cancel()`,
`workflow.submit_signoff()` to the Starlark module. Extract engine
interface to break circular import.

**v0.9.8 — Conditional Routing → SDK Primitive**

Expose `routing.evaluate(rules, data)` as a Starlark SDK function.
Branch rules become a reusable decision engine for any extension.

**v0.9.9 — Surface Access via Roles**

Wire team roles (v0.9.3) into surface access declarations:
`access: role:approver`. Kernel middleware checks role membership.
Completes the workflow→package access story.

---

### v0.10.x — Panels + Composable Layout

Panels are a new kernel rendering tier between surfaces (full-page) and
block renderers (inline). They solve composable companion views — e.g.,
a notes reference panel inside chat. Design doc: `docs/DESIGN-panels.md`.

| Version | Title |
|---------|-------|
| v0.10.0 | Panel Manifest + Lifecycle |
| v0.10.1 | FloatingPanel Primitive |
| v0.10.2 | Docked Panels + Mode Transitions |
| v0.10.3 | Panel Communication Patterns |
| v0.10.4 | Reference Panel: Notes (basic) |

---

### v0.11.x — Notes Reference Extension

Notes becomes the first reference extension — a production-quality
knowledge base that exercises every kernel primitive. The UI/UX redesign
is front-loaded as v0.11.0 so every subsequent feature version builds on
a clean visual foundation. Design doc: `docs/DESIGN-notes-v011x.md`.

| Version | Title |
|---------|-------|
| v0.11.0 | UI/UX Foundation — visual redesign |
| v0.11.1 | Deep Folders + Navigation |
| v0.11.2 | Wikilinks + Backlinks |
| v0.11.3 | Live Preview + Rich Editing |
| v0.11.4 | Note Sharing + Permissions |
| v0.11.5 | Graph + Outline Hardening |
| v0.11.6 | Quick Switcher + Commands |
| v0.11.7 | Daily Notes + Templates |
| v0.11.8 | Transclusion + Embeds |
| v0.11.9 | Composability: Slots + Actions |
| v0.11.10 | Panel Enhancement + Quality Gate |

---

### v0.12.x — Reference Extensions (Remaining)

The kernel is complete. This series proves the platform by shipping
first-party extensions that exercise every primitive. These are
**extensions, not kernel code** — they ship as `.pkg` files and can be
uninstalled.

| Version | Title |
|---------|-------|
| v0.12.0 | `vector-store` Library |
| v0.12.1 | `llm-bridge` Library |
| v0.12.2 | `file-share` Extension |
| v0.12.3 | `code-workspace` Extension |
| v0.12.4 | `image-gen` + `image-edit` Extensions |
| v0.12.5 | Chat System |

---

### v0.13.x — Sidecar Tier + Polish

| Version | Title |
|---------|-------|
| v0.13.0 | Sidecar Tier |
| v0.13.1 | Native Dialog Audit |
| v0.13.2 | Stability + Migration Tooling |

---

### v1.0.0 — Stable Release

Kernel API surface frozen. Extensions are the product.

Gate criteria:

- All kernel Starlark modules documented with examples
- All `api_routes` covered by OpenAPI spec
- Upgrade path tested from v0.8.0 → v1.0.0
- At least 3 reference extensions shipped (vector-store, llm-bridge, chat)
- At least 1 cross-extension composability demo (image-gen → chat:image-actions)
- Headless E2E green on PG + SQLite
- `armature-ca.sh` + mTLS deployment guide
- Single-binary + Docker + K8s deployment paths documented
- Notes reference extension shipped with all v0.11.x features
- Notes UI/UX reviewed against v0.11.0 design principles — no placeholder UI
- At least 1 panel shipped and consumed cross-package (notes.reference → chat)
- Panel lifecycle test coverage in SDK test runner

---

## Post-1.0 Horizon

These are candidates, not commitments. Each requires a design doc.

- **Federation** — cross-instance package sharing, identity federation
- **Package marketplace** — signing, review, discovery registry
- **Desktop app** — Tauri wrapper for local-first deployment
- **Offline/sync** — SQLite-first with PG sync for field deployments
- **Multi-tenant SaaS mode** — tenant isolation at the team boundary

---

## Design Principles

| Principle | Implication |
|-----------|-------------|
| Extensions are the product | Chat, tasks, LLM, vector search, file sharing — all extensions. Zero kernel awareness of domain logic. |
| Kernel stays thin | New kernel primitives require justification. If it can be an extension, it must be. |
| Progressive enhancement | Every feature works on SQLite. PG adds performance. pgvector adds native vectors. S3 adds scalable storage. |
| KISS-first | No unnecessary dependencies. Preact+htm (3KB), single binary, dual-DB from one codebase. |
| Changeset discipline | Each CS independently CI-green. Design docs as implementation contracts. |
| Pre-1.0 migration freedom | Schema changes fold into existing migrations. Post-1.0: proper versioned migrations. |

---

## Design Decisions Log

| Decision | Rationale |
|----------|-----------|
| Tasks → extension | Three trigger primitives replace the monolithic scheduler. |
| Sessions removed | Workflow instances with dedicated storage replace kernel sessions. |
| `custom` stage mode | Delegates to a surface package, proving extension composability. |
| Providers removed from kernel | Connections + Starlark `provider.complete` as the interface. |
| Kernel permissions simplified | 6 platform permissions. Extensions define their own. |
| Preact+htm retained | 3KB runtime, no build step, KISS. |
| Single Docker image | Go binary + assets + migrations. |
| Admin → RBAC group | Grant check replaces role check. |
| Settings cascade | Scope auth + `user_overridable`. Two orthogonal axes. |
| Chat as extension, not kernel | Zero kernel awareness. Proves extensibility thesis. |
| PG as consensus layer | UNLOGGED node_registry + LISTEN/NOTIFY. No etcd/Consul/Redis. |
| Two trigger tiers | Extension-declared (full sandbox) vs user ad-hoc (restricted). |
| Two-slot topbar model | Left slot (title/branding) + center slot (`flex: 1`, tabs/pickers). |
| `db` module is the structured store | No separate KV primitive. Extensions declare tables. |
| `files` module rides ObjectStore | No new kernel tables. Metadata as companion objects. |
| `workspace` for real filesystem | Flat blob store can't serve git/compilers/ffmpeg. Managed disk paths. |
| Capability negotiation at install | Fail loud with actionable message, not silently at runtime. |
| Vector column with three-tier fallback | Works everywhere, works fast with pgvector. |
| Sidecar deferred to v0.13.x | HTTP module covers external APIs. Sidecars connect inward (no k8s RBAC needed). |
| Workflow redesign before reference extensions | Clean up debt and promote primitives before building on top. |
| Panels as kernel primitive (v0.10.x) | Z-index coordination, drag/resize, layout negotiation are kernel concerns. |
| UI/UX redesign as v0.11.0 | Every feature version builds on the visual foundation. Front-loading avoids double work. |
| Notes as dedicated v0.11.x series (11 versions) | Complex enough to need changeset discipline. Each version independently shippable. |
| Notes before remaining reference extensions | Notes proves the full primitive surface. Other extensions build on proven patterns. |
