archvillainette dc93feb176 Topdata Migration (#2)
Native topdata migration summary

- Replaced the legacy 2dabuilder runtime path with the native topdata builder.
- Native build, validate, compare, and convert flows now cover the canonical topdata pipeline.
- compare-topdata is now a native self-check; legacy reference-builder runtime usage was removed.
- Parts generation follows the native asset-scan contract and uses sow-assets via project asset resolution.
- Generated feat families, class-feat injects, masterfeat/successor expansion, and dataset-derived feat generation were brought to parity and regression-covered.
- Remaining mirrored datasets were migrated into native-owned canonical data while preserving lock IDs.
- normalize-topdata bridge behavior and migration-era ownership markers were removed.
- Documentation was rewritten around the native workflow and active contracts were cleaned up.
- Final hardening pass removed stale validator assumptions and cleaned ignored/generated artifacts for PR readiness.

# sow-tools
Shared NWN build tooling for Shadows Over Westgate.
This repository owns the Go-based `sow-toolkit` binary used by the separate module and assets repositories.
## Build
Build the development binary into `tools/sow-toolkit`:
```bash
./build-tool.sh
```
Or run directly with Go:
```bash
GOCACHE="$PWD/.cache/go-build" go run ./cmd/nwn-tool --help
```
## Repository Layout
```text
cmd/nwn-tool/ CLI entrypoint
internal/app/ command wiring and console UX
internal/erf/ ERF/MOD/HAK reading and writing
internal/gff/ canonical GFF JSON and binary conversion
internal/pipeline/ build, extract, compare, and manifest workflows
internal/project/ config loading and repo scanning
internal/validator/validation and diagnostics
tools/ built development binary output
```
## Intended Consumers
- `sow-module` uses `sow-toolkit` for `build-module`, `extract`, `validate`, `compare`, and `apply-hak-manifest`
- `sow-assets` uses `sow-toolkit` for `build-haks` and validation
- validation now fails early if duplicate asset resources would collide inside the same generated HAK
- duplicate resources split across different HAK groups remain warnings because later HAK order can still override earlier content at runtime
- `sow-module` now also uses `sow-toolkit` for topdata:
- `validate-topdata`
- `build-topdata`
- `compare-topdata`
- `convert-topdata`
During development, sibling repositories can point at `../sow-tools/tools/sow-toolkit`. For pinned releases, each consumer repo can instead carry its own copy at `tools/sow-toolkit`.
## Release Automation
This repo publishes:
- `sow-toolkit-linux-amd64.tar.gz`
- `sow-toolkit-windows-amd64.exe`
Consumer repos can fetch those binaries into their local `tools/` directory with:
- `install-tool.sh` on Linux/macOS
- `install-tool.ps1` on Windows
## TopData
The native topdata system is implemented in this repo and authored in `sow-module`.
High-level ownership split:
- `sow-tools`
- owns the `sow-toolkit` implementation
- owns topdata validation, build, compare, conversion, and dataset-resolution logic
- `sow-module`
- owns canonical topdata authored data under `topdata/data/`
- owns the user-facing topdata workflow scripts
For a human-readable front-to-back explanation of how the native topdata builder works
and how to use it, see:
- [sow-module/topdata/README.md](../sow-module/topdata/README.md)
Important topdata contracts still live here under `internal/topdata/` because they are
code-adjacent implementation contracts, not user workflow docs.
