chore: bring the repo to the QRun qbit standard, add producer, tables and home

Repository standard (LICENSE, NOTICE, community pointers, CHANGELOG,
CLAUDE/AGENTS, dependabot, CircleCI with the configure-package-install
pre-step, the release-rc caller workflow, Maven wrapper, checkstyle,
JaCoCo gates, QQQ 4.1.0-RC.5). DataAnalysisQBitProducer and config, the
six data_analysis_ tables with standard permission rules and user record
locks, the analyze permission stand-in, the Analyses app home with real
counts, and the Postgres schema script.

This file provides guidance to Claude Code when working with code in this repository.

Project Overview

QBit Data Analysis: statistical analysis and data dives on any table, filter or saved view. Design: QRun-IO/qqq#1137, docs/DATA-ANALYSIS.md in QQQ. Repository phase: metadata, permissions and Analyses home summary. Computation and UI phases a-f are planned.

Build Commands

./mvnw compile
./mvnw test
./mvnw verify  # Checkstyle, tests, JaCoCo: 70% instructions, 90% classes

Always use the wrapper (Maven 3.9.11); Maven 3.10 cannot read the parent POM.

Architecture

Entry point: DataAnalysisQBitProducer implements QBitMetaDataProducer<DataAnalysisQBitConfig> in com.kingsrook.qbits.dataanalysis. Component producers are scanned only in metadata. Tables live in model, widgets in app, permission helpers in permissions.

Invariants

Queries use the current user's session and enforced permissions.
Saved analyses remain owner-locked; the shared flag does not broaden READ yet. See README Security.
Hosts populate data_analysis_user with the session user id; only administrators get the data_analysis.admin all-access security key.
Real counts only. Schedules and stars are children of saved analyses. No processes in navigation.

Naming

Tables: data_analysis_<name>; SQL names equal QQQ table names. Table PVS use the table name.
Permissions: data_analysis.saved.*, data_analysis.watch.*, data_analysis.settings.*, data_analysis.run.* (standard rules, no custom checker), data_analysis.admin (lock all-access key), plus <effective table permission base>.analyze per analyzed table.
Data lives in visible standard QQQ tables with permissions and record locks.

Code Style

Copy the Apache header from existing Java files; 3-space indent, Allman braces, return (x);.
Flower-box Javadoc on every class and method; fluent withX() setters.
Wrapper types in config and entities; JUnit 5 and AssertJ tests.

Dependencies

Java 21; parent com.kingsrook:qbit-build-parent:2.0.0. Default-active qqq-snapshot imports QQQ 4.1.0-RC.5 ahead of the parent's 4.0.0 BOM (ADR-0007); remove activation when the parent moves to 4.1. Middleware Javalin is optional. RDBMS, H2, PostgreSQL driver and Testcontainers are test-only for later pushdown tests. Later phases need core aggregate extensions and the UI API extension point (#1128, RC.6).

Release

CircleCI qqq-orb 0.6.8: develop publishes SNAPSHOTs, release/* publishes RCs (orb version bumps), vX.Y.Z publishes releases. No manual publishing.
