## Issues Found and Resolved
7

8
### Critical Issues Fixed:
9

10
1. **Wrong Package Scope**: Original k-tile documented `@chart-plugins/plugin-chart-sunburst` (a single chart plugin) instead of `apache-superset` (the entire business intelligence platform)
11

12
2. **Incorrect Manifest Format**: `tile.json` didn't follow Knowledge Tile specification and contained wrong package information
13

14
3. **Missing Required Structure**: No `docs/` directory structure as required by Knowledge Tile format
15

16
4. **Incomplete API Coverage**: Only covered one chart plugin instead of the entire Superset API surface
17

18
5. **Wrong Package Type**: Claimed to be npm package when Apache Superset is a Python/PyPI package
19

20
### Resolution Actions:
21

22
1. **Correct Manifest**: Created proper `tile.json` following Knowledge Tile specification:
23
   - `name`: "tessl/pypi-apache-superset"
24
   - `version`: "1.0.1" 
25
   - `describes`: "pkg:pypi/apache-superset@1.0.1"
26
   - `docs`: "docs/index.md"
27
   - `summary`: Accurate description of Apache Superset
28

29
2. **Comprehensive Documentation**: Created complete API documentation covering:
30
   - **Entry-point doc** (`docs/index.md`): Overview, package info, core imports, basic usage, architecture, and capability summaries
31
   - **CLI Commands** (`docs/cli-commands.md`): All 20+ command-line operations
32
   - **REST API** (`docs/rest-api.md`): Complete REST endpoints for charts, dashboards, datasets, databases, queries, and security
33
   - **Configuration** (`docs/configuration.md`): All configuration categories including security, caching, database, and feature flags
34
   - **Models and Database** (`docs/models-database.md`): SQLAlchemy models for all major entities
35
   - **Security and Authentication** (`docs/security-auth.md`): RBAC, OAuth, RLS, and permission systems
36
   - **Visualization System** (`docs/visualization.md`): Chart types, plugin architecture, and data processing
37

38
3. **Proper Structure**: Created correct Knowledge Tile directory structure with all required sections and API blocks marked with `{ .api }`
