Jon Chery 675feabf0c feat(P09): Syncthing storage replication + conflict resolution (REQ-081; gates C-02, C-14)
P09 — Storage replication via per-namespace Syncthing (R-005).

C-02 spike (.ciagent/C02_SYNCTHING_FEASIBILITY_v0.9.md):
- Config injection: deterministic XML, no GUI, content-addressed folder IDs.
- Conflict policy: flock-style lock + source-wins migration + gc-conflicts.
- Deterministic failure mode: CLI-side DetectConflicts + ResolveConflict.
- Auto-decision: C-02 SATISFIED.

C-14 forced-divergence test (internal/storage/conflict_test.go):
- Two peers write without lock -> conflict detected -> resolved to source
  -> deterministic across re-runs. Unknown source -> nil (no silent winner).
- C-14 SATISFIED.

Replication (internal/storage/replication.go, REQ-081):
- FolderID = sha256(ns+masterKeyFP)[:32] (content-addressed).
- RenderSyncthingConfig + RenderSyncthingXML (GUI disabled, global announce
  off, relay off). DetectConflicts (sorted, deterministic). ResolveConflict
  (source-peer-wins). 97.6% coverage.

Emitter (internal/emitter/syncthing.go):
- SyncthingEmitter renders one config.xml per replicated volume at
  /etc/syncthing/orca-<ns>-<volume>.xml. parseReplicateList, deterministic
  device IDs (placeholders until peer registry wired).

24 packages pass, 20 bats pass, gofmt clean, verify-reqs 90 consistent.

Orca

Offline/CLI-first orchestration engine inspired by HashiCorp Nomad, far simpler than Kubernetes.

Status

v0.1: Foundation — see .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

Install (1-liner)

# User-level install (binary at ~/.local/bin/orca, state at ~/.orca)
curl -fsSL https://git.cloudinit.dev/coreci/orca/raw/branch/main/scripts/install.sh | bash

# System-level install (binary at /usr/local/bin/orca, state at /root/.orca)
curl -fsSL https://git.cloudinit.dev/coreci/orca/raw/branch/main/scripts/install.sh | sudo bash -s -- --system

# Pin a specific version
curl -fsSL https://git.cloudinit.dev/coreci/orca/raw/branch/main/scripts/install.sh | bash -s -- --version v0.4.2

Then initialize local state and verify:

orca init          # creates ~/.orca/ (or /root/.orca with --system)
orca version       # prints version info
orca --help        # show all subcommands

Build from source

make build         # Build binary to ./bin/orca
./bin/orca init    # Initialize local state
./bin/orca version # Verify

Update in place

Re-running the installer updates the binary while preserving your config, database, and certificates in the namespace dir:

curl -fsSL https://git.cloudinit.dev/coreci/orca/raw/branch/main/scripts/install.sh | bash
# → "updated orca from v0.4.1 to v0.4.2"

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

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)
