## Installed production graph and browser bundle

| Package | Version | License | Purpose | License text |
| --- | --- | --- | --- | --- |
| `@jridgewell/trace-mapping` | 0.3.31 | MIT | Decode regular and indexed/sectioned maps with `AnyMap`, then query mappings | [MIT](./licenses/jridgewell-trace-mapping-0.3.31-MIT.txt) |
| `@jridgewell/resolve-uri` | 3.1.2 | MIT | Resolve source and map URLs | [MIT](./licenses/jridgewell-resolve-uri-3.1.2-MIT.txt) |
| `@jridgewell/sourcemap-codec` | 1.6.0 | MIT | Decode and encode mapping segments | [MIT](./licenses/jridgewell-sourcemap-codec-1.6.0-MIT.txt) |
| `path-browserify` | 1.0.1 | MIT | Path compatibility code embedded in the browser artifacts | [MIT](./licenses/path-browserify-1.0.1-MIT.txt) |

Only `@jridgewell/trace-mapping@0.3.31` is a direct runtime dependency. The
other two @jridgewell packages are its exact resolved transitive dependencies.
`path-browserify@1.0.1` is a development dependency whose code is bundled into
the packed browser artifacts, so its MIT notice remains a release obligation
even though npm does not install it as a production dependency. Other build,
test, lint, and type-checking tools are development-only and are not installed
or embedded in the production package.

Thus the installed production graph contains the three exact @jridgewell
components, while each packed browser artifact contains those same three plus
`path-browserify@1.0.1`: four bundled materials and four retained MIT texts.
