# Reference Baskets

> Methodology for Philidor-published reference baskets: eligibility, weighting, caps, refresh schedule, and halt conditions.

Philidor publishes reference baskets that aggregate vetted constituents under a single, transparent methodology. Each basket is computed autonomously by the basket-rebalancer worker from the same Philidor risk ratings that power our public scores; the rules below are the single source of truth for both the API JSON and these documentation pages.

## Available Baskets

| Basket                                                                      | Constituent Type | Minimum Constituents | Version |
| --------------------------------------------------------------------------- | ---------------- | -------------------- | ------- |
| [RWA T-Bill Conservative](/docs/methodology/baskets/rwa-tbill-conservative) | asset            | 5                    | 1.0.0   |
| [T-Bill Anchored DeFi](/docs/methodology/baskets/tbill-anchored-defi)       | vault            | 8                    | 1.0.0   |

## Shared Properties

All Philidor reference baskets share the same envelope: eligibility filter (Prime/Core + reviewed), score-weighted construction with a 7.0 pivot, the same single-name / issuer / floor caps, the same calendar-plus-rating-move refresh contract, and the same halt-closed invariants. The differences between baskets live in the eligibility rule (which universe of constituents is admitted) and in the constituent type (assets vs. vaults).

## Governance

Methodology changes ship as data, not code: a new `basket_methodology_versions` row is activated, the rebalancer picks up the new version on its next run, and these MDX pages are regenerated from the same TypeScript source-of-truth that the rebalancer reads. CI fails if the committed MDX drifts from the regenerator output, so the API JSON and the documentation cannot diverge.
