Changelog

Unreleased (v0.6)

Synthetic tools refreshed: gambit_init, gambit_respond, gambit_complete (function-style tools, underscore names).
Envelope simplification: init carries run/action IDs plus guardrails/model hints; respond wraps payload/message/status/code/meta (default status 200 for success, 500 for handled errors unless overridden).
Runtime behavior: child completions and handled errors emit gambit_complete; interval handlers surface mid-run updates; roots stay conversational-only.
Docs/memos updated to reflect the minimal scope and naming.
IO/host: --message sends a first user turn; --init seeds gambit_init without changing turn order; REPL/serve/cli flags updated accordingly.
IO/host: gambit_init now only fires when --init is provided and its payload is just the raw input (no run/action metadata).
IO/host: --verbose tracing now logs tool call arguments and results.

Authoring: TypeScript/Markdown decks and cards via defineDeck/defineCard; embeds with cycle detection; card actions merge into decks (deck wins); card schema fragments merge into deck schemas; non-root decks require input/output schemas (root defaults to string-ish).
Runtime: compute and LLM decks share the surface; assistant-first flow seeds a synthetic gambit_init tool; helpers spawnAndWait, return, fail; action names validated against reserved prefix/pattern/length; default guardrails depth=3/passes=3/timeout≈120s with per-deck overrides.
Handlers/events: optional onError/onBusy/onIdle decks emit structured events (gambit_complete for handled errors, busy/idle updates) with default delay 800ms and traces for fire/result (onInterval is deprecated alias for onBusy).
IO/host: CLI supports run, repl, serve (WebSocket simulator UI); flags for streaming, turn order via user message, trace to console/JSONL, state load/save, model overrides; deno task compile builds a binary; OpenRouter chat provider with streaming/tool calls.
Runtime + server tests for schemas/embeds/streaming/handlers; tasks for fmt/lint/test/ci; root README with quick start.
