A Go module under tools/local-dev/legacy-report that converts the
"dg" / "gplus" engine .REP files in tools/local-dev/reports/ into the
JSON shape of pkg/model/report.Report. The output drives a DEV-only
synthetic-mode loader on the UI lobby so the map, inspectors, and
order-overlay can be exercised against rich game states without
playing many turns end-to-end.
Scope is intentionally narrow: only the fields the UI client decodes
today (planets, players, own ship classes, header). Importing
pkg/model/report keeps the parser and the typed contract in lockstep
— any backwards-incompatible schema change breaks the tool's
compilation before it ships. The README spells out the parity rule
for extending the parser alongside future UI decoders.

Compile `ui/core` to WebAssembly via TinyGo (903 KB) and expose four
canonical-bytes / signature-verification functions on
`globalThis.galaxyCore` from `ui/wasm/main.go`. The TypeScript-side
`Core` interface plus a `WasmCore` adapter (browser + JSDOM loader)
bridge those into a typed shape, and a `GalaxyClient` skeleton wires
`Core.signRequest` → injected `Signer` → typed Connect client →
`Core.verifyPayloadHash` / `verifyResponse`.
Wire `ui/buf.gen.yaml` against the local
`@bufbuild/protoc-gen-es` v2 binary (devDependency) so the codegen
step does not depend on the buf.build BSR. Vitest covers the bridge
end-to-end: per-method WasmCore tests under JSDOM, byte-for-byte
canon parity against the gateway fixtures committed in Phase 3, and
a `GalaxyClient` orchestration test using
`createRouterTransport`. The committed `core.wasm` snapshot tracks
TinyGo output so contributors run `make wasm` only when `ui/core/`
changes; CI consumes the snapshot directly.
