Start here when orienting to the project. Top-level docs are the current reference unless marked otherwise. Historical scratch notes and completed implementation plans are kept for context, not as active instructions.

Current Overview

project_map.md: package map, entrypoints, examples, tests, and verification commands.
current_roadmap.md: active next-work list after the core type-shape cleanup.
wf_core_architecture.md: kernel package boundaries, runtime flow, validation flow, and known runtime gaps.
wf_mcp_architecture.md: MCP package boundaries, dependency rules, reload/proxy behavior, and extraction seams.

Core Workflow Model

core_state_mapping_and_merge.md: canonical input / output bindings, interrupt request / resume bindings, state patch rules, reducers, and merge semantics.
structural_refs.md: structural source/capability refs and structural graph/local/state path JSON.
schema_validation.md: JSON Schema validation seam and current payload validation limits.
workflow_artifacts.md: saved workflow artifacts, deployments, dependency compatibility, and interrupt limitations.
workflow_drafts.md: LLM/human draft authoring format above raw workflow plans.

Authoring

authoring_sketch.md: authoring layer direction, NodeSpec, builder API, and catalog goals.
wf_authoring_control_flow.md: when to use branch, handle, match, when, and choose.

MCP Platform

wf_mcp_operator_manual.md: operator/client guide for connections, catalog discovery, drafts, artifacts, deployments, and troubleshooting flow.
wf_mcp_end_to_end_runbook.md: full run from connection setup to capability discovery to deployment execution.
wf_mcp_capability_sources.md: source model for raw capabilities, workflow-ready node specs, admin tools, and docs.
workflow_capabilities.md: distinction between raw capabilities, workflow capabilities, wrappers, artifacts, and deployments.
wf_mcp_proxy_reality_and_roadmap.md: practical proxy behavior, FastMCP gaps, and local workaround boundaries.
wf_mcp_troubleshooting.md: common MCP/server failure modes.

Protocol Notes

mcp_protocol_proxy_inventory.md: MCP protocol surface inventory for proxy support.
mcp_stateful_runtime_plan.md: stateful MCP runtime planning notes.
FastMCP issue notes: fastmcp_resource_link_issue_guide.md, fastmcp_resource_link_issue_lda_tries.md, fastmcp_notification_forwarding_issue_lda_tries.md.

Historical Material

historical/scratchpad.md: older graph/model design notes.
historical/path_mapping_scratch.md: older path and mapping design thread.
superpowers/plans/: mostly completed implementation plans and execution records. Use them for context, not as the primary source of truth.
superpowers/specs/: design specs produced during planning sessions.

Future Runtime Work

Two runtime features may come back after the platform/DX roadmap advances:

Native subgraph execution with child run state, interrupt bubbling, and resume back into the child workflow.
Concurrent foreach with explicit scheduling, reducer/merge semantics, and failure policy. Sync runtime can interleave item frames deterministically; async runtime can add simultaneous async node handler execution. Do not implement this as plain asyncio.gather over sync handlers.
