Symphony Go

Go implementation of the core Symphony service from the upstream SPEC.md.

Build one static binary:

CGO_ENABLED=0 go build -buildvcs=false -trimpath -ldflags='-s -w' -o bin/symphony ./cmd/symphony

Run it with a repository-owned workflow file:

export LINEAR_API_KEY=...
./bin/symphony /path/to/repo/WORKFLOW.md

Implemented core behavior:

• WORKFLOW.md loading with YAML front matter, Liquid prompt rendering, defaults, $VAR, ~, relative workspace roots, validation, and live reload.
• Linear GraphQL candidate polling, terminal-state startup cleanup, and issue-state reconciliation.
• Deterministic per-issue workspaces with path containment checks and lifecycle hooks.
• Bounded orchestration with active/terminal filtering, Todo blocker checks, priority sorting, continuation retries, failure backoff, and stall cancellation.
• Codex app-server launch over stdio with the configured approval and sandbox policy.

Documented runtime posture:

• Default Codex approval policy rejects sandbox approval, rules, and MCP elicitation requests unless the workflow overrides it.
• Default thread sandbox is workspace-write.
• Default turn sandbox policy is workspaceWrite rooted at the issue workspace with network disabled unless the workflow overrides it.
• User-input-required and approval-required app-server flows are not auto-resolved by this implementation; they fail by timeout or app-server failure rather than waiting for an operator channel.

Extensions such as a web dashboard, SSH workers, and the optional linear_graphql dynamic tool are not included in this core binary.
