v0.1.5

Added

Auth Command

• New sp auth command (src/commands/auth.ts) for global API key management in ~/.sapling/auth.json
• Subcommands: auth set <provider>, auth show, auth remove <provider>
• Supports anthropic and minimax providers with optional --base-url override
• Auth store wired into loadConfig as credential fallback when env vars are unset
• Full test coverage (src/commands/auth.test.ts)

Event System Overhaul

• Standardized NDJSON event stream for overstory parseEvents() compatibility
• Renamed events for consistency; added setState event for agent state broadcasting
• New progress() event for dashboard visibility of long-running operations
• EventConfig lifecycle hooks (onStart, onEnd) for overstory watchdog heartbeats
• All RPC requests drained per turn (not just one) for reliable multi-request handling

RPC Enhancements

• New getState RPC method for synchronous agent health queries
• followUp RPC injection differentiated from steer in the loop (no [FOLLOWUP] prefix)
• RPC acknowledgment events include argsSummary field

Backend Changes

• CC and Pi subprocess backends deprecated in favor of SDK-only (warnings emitted on use)
• Model alias resolution — short names like sonnet or opus resolve to full model IDs
• ANTHROPIC_AUTH_TOKEN supported as fallback for ANTHROPIC_API_KEY
• CLAUDECODE dead code removed from backend detection

Doctor

• sp doctor now checks auth store status and reports configured providers

Testing

• New auth command tests (src/commands/auth.test.ts) — 214 lines
• New RPC server tests for getState method
• New RPC channel tests for multi-request draining
• New loop tests for event lifecycle hooks and follow-up injection
• New event emitter tests for progress(), setState, and lifecycle hooks

Fixed

• [FOLLOWUP] prefix no longer injected into follow-up task context (was polluting LLM input)
• Missing argsSummary in RPC acknowledgment events
• Auth store credential fallback wired into config loading (keys from ~/.sapling/auth.json now used when env vars are absent)

Changed

• Test suite grown from 470 tests / 32 files / 1273 expects to 520 tests / 33 files / 1400 expects
• Event names standardized for overstory compatibility (breaking change for --json consumers)
• CC and Pi backends emit deprecation warnings; SDK is now the recommended backend
