Crate arrow_kanban 

nusy-kanban — Arrow-native kanban engine for NuSy.

Provides:

• Config — parse .yurtle-kanban/config.yaml (dual boards, WIP limits, state graphs)
• Schemas — Arrow table definitions for items, relations, runs
• Item Types — 12 types across development and research boards
• ID Allocation — sequential, conflict-safe ID assignment
• State Machine — valid transitions, WIP limit enforcement
• CRUD — create, read, update, delete items with audit trail
• Relations — cross-item and cross-board links
• Persistence — Parquet-backed load/save
• Query — NL + structured filter extraction
• Display — terminal table and board rendering
• Export — markdown + next-id output
• Migration — parse Yurtle markdown files into Arrow tables

Modules

base64

Minimal base64 encode/decode — no external crate dependency.

client

NATS client mode — send kanban commands to a remote server.

comments

Item comments — threaded, resolvable comments stored in Arrow RecordBatches.

config

Board configuration — parse .yurtle-kanban/config.yaml.

critical_path

Critical path analysis — topological sort, dependency depth, and worklist generation.

crud

CRUD operations on the kanban items store.

display

Display formatting — render items and board views to terminal output.

experiment_runs

Experiment run tracking for the HDD (research) board.

export

Export — render Arrow items to various formats.

hdd

HDD (Research board) commands — create research items with auto-linking.

hooks

Event hooks — config-driven actions triggered by kanban operations.

id_alloc

ID allocation — scan items table for max ID per type, allocate next.

item_type

Item types for the dual-board kanban system.

mcp_server

MCP (Model Context Protocol) server for nusy-kanban.

migrate

Migration — parse Yurtle-format markdown files into Arrow tables.

persist

Persistence — load and save KanbanStore from/to Parquet files.

persistence

Kanban persistence engine — WAL + atomic Parquet save, dogfooding arrow-graph-git.

query

Query engine — NL filter extraction, SPARQL subset, and hybrid search.

relations

Relations — cross-item and cross-board links.

schema

Arrow schemas for the kanban engine tables.

state_machine

State machine — valid transitions and WIP limit enforcement.

stats

Analytics — velocity, burndown, and agent throughput from RunsTable.

templates

turtle_builder

TurtleBlockBuilder — auto-generates fenced turtle blocks for research items.

validate

SHACL-driven conformance checking for kanban items.
