## Path-level derivation inventory

Paths are relative to the package root. Every listed donor path is pinned to the commit above and is authored by ZaganJade under the MIT License.

| Destination path | Donor path | Derivation |
| --- | --- | --- |
| `src/{config.ts,format.ts,freshness.ts,prices.ts,zai.ts}` | `usage/src/{config.ts,format.ts,freshness.ts,prices.ts,zai.ts}` | Copied; formatting-only changes may be applied by this repository. |
| `src/aggregate.ts` | `usage/src/aggregate.ts` | Adapted on top of the donor scanner: recursive delegated child discovery, optional `subagents:record` enrichment, direct/delegated partitions, token-composition totals, and concurrency statistics. Core attribution (model/project/skill/bundle/plugin/tool) is retained donor code. |
| `src/cache.ts` | `usage/src/cache.ts` | Adapted for cache v6: raw per-session child summaries, per-file delegation records, exclusion fingerprints, and the reworked entry shape. Donor structure and load/save behavior retained. |
| `src/view.ts` | `usage/src/view.ts` | Adapted to add the Delegation view and a final line-width clamp, rename the Agents view to Providers, and render token composition and concurrency stats. Donor view layout, quota bars, and other views are retained. |
| `src/mascot.ts` | `usage/src/mascot.ts` | Adapted to add the Delegation view tab and rename the Agents tab to Providers. Donor poses, glyphs, and captions are retained. |
| `src/index.ts` | `usage/src/index.ts` | Adapted to pass the extension context's model registry into provider credential resolution and to register the new `/usage-delegation` and `/usage-providers` commands (with `/usage-agents` kept as an alias). Commands, widget behavior, and UI behavior are otherwise retained. |
| `src/provider.ts` | `usage/src/provider.ts` | Adapted to replace unavailable `AuthStorage` methods with public model-registry credential APIs and derive the Codex account ID from the refreshed access token. |
| `test/{freshness.test.ts,provider.test.ts}` | `usage/src/{freshness.test.ts,provider.test.ts}` | Copied upstream behavioral tests (kept out of the published tarball); test-runner imports adapted to the repository's Vitest workspace. |
| `test/provider-credentials.test.ts` | `usage/src/provider.ts` | Local regression tests for the adapted credential and Codex quota behavior. |

`test/aggregate.test.ts` and `test/discovery.test.ts` are new local work and are not adapted from donor code.

Pinned source URLs for each row are formed by appending the donor path to https://github.com/ZaganJade/pi-extension/blob/2de5ac6bd6a802338d78e9daba1f29a4a74e29d3/ (use `/tree/` for grouped paths).
