-# Architecture: Orchestration Engine
+# Architecture: Orca

-(Initial Draft)
-The system will consist of:
-1. **CLI Tool**: The primary interface for users and AI agents.
-2. **Controller/Server**: A lightweight daemon managing state and scheduling.
-3. **Agent/Worker**: A daemon running on each node to execute workloads.
-4. **State Store**: A simple, local-first state persistence mechanism.
+## System Overview

-## Design Pillars
- Security before features.
- Bug fixes before features.
- NFRs before features.
+Orca is a single-binary, offline-first orchestration engine. The system consists of three logical components, all compiled into one `orca` binary and selected via subcommands.

+## Component Details
+
+### 1. CLI Layer (`cmd/orca`, `internal/cli`)
+- **Framework**: Cobra (industry standard, familiar to operators)
+- **Subcommands**: `version`, `init`, `status`, `node`, `job`
+- **Output**: Human-readable by default; `--json` flag for machine consumption
+- **Discovery**: All subcommands self-document via Cobra's auto-generated help
+
+### 2. Daemon Layer (`internal/daemon`)
+- **Server**: `net/http` with `http.ServeMux` (no external router for v0.1)
+- **TLS**: `crypto/tls` with self-signed certs (mTLS-ready)
+- **Ports**: Configurable (default `:8443` for API, `:8080` for health)
+- **Graceful Shutdown**: `signal.NotifyContext` with SIGINT/SIGTERM
+
+### 3. Core Engine (`internal/engine`)
+- **Node Registry**: In-memory map of node IDs → metadata, persisted to SQLite
+- **Task Executor**: `os/exec.CommandContext` with `WaitDelay` (Go 1.25+) for clean process termination
+- **Job Scheduler**: Single-node FIFO queue (multi-node deferred to v0.2+)
+- **Audit Logger**: `slog.NewJSONHandler(os.Stderr, ...)` with structured fields
+
+### 4. State Store (`internal/store`)
+- **Driver**: `modernc.org/sqlite` (pure Go, CGO-free)
+- **Location**: `~/.orca/orca.db` (user-mode) or `/var/lib/orca/orca.db` (system-mode)
+- **Schema**: `nodes`, `jobs`, `tasks`, `audit_log` tables
+- **Migrations**: Embedded SQL files, applied on startup
+
+## Data Model
+
+### Node
+```go
+type Node struct {
+    ID        string
+    Name      string
+    Address   string
+    State     string
+    JoinedAt  time.Time
+    LastSeen  time.Time
+    Metadata  map[string]string
+}
+```
+
+### Job
+```go
+type Job struct {
+    ID        string
+    Name      string
+    Spec      string
+    Status    string
+    CreatedAt time.Time
+    StartedAt *time.Time
+    EndedAt   *time.Time
+}
+```
+
+### Task
+```go
+type Task struct {
+    ID        string
+    JobID     string
+    Command   string
+    Args      []string
+    Env       []string
+    PID       int
+    ExitCode  int
+    Status    string
+    CreatedAt time.Time
+    StartedAt *time.Time
+    EndedAt   *time.Time
+}
+```
+
+## Security Architecture
+
+### Authentication
+- **v0.1**: mTLS for all API endpoints (self-signed CA)
+- **v0.2+**: Token-based auth as alternative
+
+### Audit Logging
+- All state-changing operations emit structured log records
+- Fields: `timestamp`, `actor`, `action`, `resource`, `result`, `error`
+- Stored in SQLite `audit_log` table and stderr (JSON)
+
+### Input Validation
+- All CLI inputs validated via Cobra's `Args`/`ValidArgs` functions
+- All API inputs validated at handler boundary
+- HCL/YAML specs parsed with strict schemas
+
+## Key Architectural Decisions
+
+| ID | Decision | Rationale |
+|----|----------|-----------|
+| AD-001 | Single binary with subcommands | Simpler distribution, aligns with simplicity pillar |
+| AD-002 | modernc/sqlite (CGO-free) | Cross-compile friendly, no CGO toolchain needed |
+| AD-003 | net/http (no framework) | Stdlib suffices; avoids external router dependency |
+| AD-004 | os/exec with WaitDelay (Go 1.25+) | Clean process termination, native to Go |
+| AD-005 | Cobra for CLI | Industry standard, familiar to operators |
+| AD-006 | slog for logging | Native to Go 1.21+, no external dependency |
+| AD-007 | HCL for job specs | Familiar to Nomad/HashiCorp users |
+| AD-008 | Single-node scheduling (v0.1) | Multi-node scheduling deferred to v0.2+ |
+
+## Anti-Patterns (Explicitly Avoided)
+
+- No controller/agent split (single binary)
+- No CRDs / custom resource definitions
+- No web UI (CLI-only)
+- No service mesh
+- No container runtime integration
+- No multi-tenancy
+- No cloud provider integrations
+- No auto-scaling
+- No admission controllers
+- No complex scheduling algorithms
+
+## Dependency Map (minimal)
+
+```
+github.com/spf13/cobra           # CLI framework
+github.com/hashicorp/hcl/v2      # HCL parser
+modernc.org/sqlite               # SQLite (pure Go)
+github.com/google/uuid           # UUID generation
+```
+
+Total: ~4 direct dependencies. No web framework, no ORM, no RPC framework.
+
+## Deployment Model
+

+## Wave Ordering
+
+- **Wave 1** (Phase 1): Foundation — CLI skeleton, build system, hooks
+- **Wave 2** (Phases 2-3): Core functionality — node registry, task execution
+- **Wave 3** (Phases 4-5): Hardening — state persistence, health checks
+- **Wave 4** (Phase 6): Release — CoreCI integration
+
+Phases within a wave can be parallelized if `parallelization.enabled=true`.
+For v0.1, `parallelization.enabled=false` — phases run sequentially.

+## Versioning

+- **Patch per phase**: `v0.1.1`, `v0.1.2`, ..., `v0.1.6`

+| D-001 | Single binary or multi-binary distribution? | **Single binary** | Simpler distribution; subcommands baked into one `orca` binary. Aligns with simplicity pillar. | 0.95 |
+| D-002 | Local state store technology? | **modernc/sqlite (pure Go, CGO-free)** | Cross-compile friendly, no CGO dependency, single file on disk, mature. | 0.92 |
+| D-003 | Inter-node communication? | **Embedded HTTP (net/http) over loopback, mTLS for cross-node** | No external RPC framework needed for v0.1. HTTP suffices. | 0.85 |
+| D-004 | Scheduling algorithm for v0.1? | **Single-node only (no scheduling)** | Multi-node scheduling is out of scope for v0.1. Tasks run on the node they're submitted to. | 0.90 |
+| D-005 | CLI output format? | **Human-readable by default, `--json` flag for machine consumption** | Serves both humans and AI agents. | 0.95 |
+| D-006 | Job/task definition format? | **HCL or YAML in `.hcl`/`.yaml` files** | Familiar to Nomad/HashiCorp users; simpler than JSON for humans. | 0.88 |
+| D-007 | Authentication? | **mTLS for v0.1, token-based deferred** | mTLS is the most secure default. Tokens can be added later if needed. | 0.80 |
+| D-008 | Container runtime? | **Direct process execution (no container runtime) for v0.1** | Avoids the Docker/container dependency. Pure process management. | 0.85 |
+| D-009 | Configuration file location? | **`~/.orca/config.hcl` and `/etc/orca/orca.hcl`** | Standard XDG-style paths. | 0.90 |
+| D-010 | Logging format? | **Structured JSON via `log/slog`** | Native Go 1.21+ slog, no external dependency. | 0.95 |

 ## Out of Scope
 - Full-blown Kubernetes-compatible API.
 - Complex cloud-provider integrations.
 - GUI-based management consoles.
+- Multi-node scheduling.
+- Container runtime integration.
+- Service mesh / sidecar injection.
+- Auto-scaling / horizontal pod autoscaler.

+# Orca
+
+Offline/CLI-first orchestration engine inspired by HashiCorp Nomad, far simpler than Kubernetes.
+
+## Status
+
+**v0.1: Foundation** — see [.ciagent/ROADMAP.md](.ciagent/ROADMAP.md) for the 6-phase plan.
+
+## Pillars
+
+- **Simplicity** — single binary, minimal dependencies
+- **AI-first** — CLI designed for both humans and AI agents
+- **Offline-first** — no cloud dependencies
+- **CLI-first** — primary interface is the command line
+- **Security before features** — NFRs ship before new functionality
+- **Bug fixes before features** — stability is paramount
+- **NFRs before features** — observability and auditability first
+
+## Quickstart
+
+```bash
+# Build
+make build
+
+# Run
+./bin/orca version
+./bin/orca --help
+
+# Initialize local state
+./bin/orca init
+```
+
+## Subcommands
+
+| Command | Description | Status |
+|---------|-------------|--------|
+| `orca version` | Print version info | ✅ Phase 1 |
+| `orca init` | Initialize local orca state | ✅ Phase 1 (stub) |
+| `orca status` | Show orca daemon status | ✅ Phase 1 (stub) |
+| `orca node` | Node management (`join`, `leave`, `list`) | Phase 2 |
+| `orca job` | Job management (`run`, `list`, `stop`, `logs`) | Phase 3 |
+
+## Development
+
+```bash
+make build      # Build binary to ./bin/orca
+make test       # Run tests with race detection
+make lint       # Run golangci-lint
+make fmt        # Format code
+make release    # Build + create Gitea release (Phase 6)
+```
