Yield Intelligence Changelog: v7 archive

Impact notes

• `dusd-dtrinity` resolves an exact DeFiLlama weighted pool group for Ethereum and Fraxtal sdUSD
• The synthetic source key starts a new history series so prior Ethereum-only rows are not treated as equivalent 30-day samples
• The dUSD metadata entry stays unchanged because its checked-in collateral and contract data already documents chain-isolated deployments

Impact notes

• `savusd-avant` now owns the Avant native savings pool directly in the yield manifest
• `avusd-avant` is no longer marked yield-bearing because avUSD is the non-yield base asset and savUSD is the yield-accruing route
• Parent-side `avusd-avant` savUSD variant and pool mappings were removed so new yield history publishes under the tracked savUSD asset

Impact notes

• `zys-zephyr-protocol` is tracked as a yield-bearing NAV wrapper over `zsd-zephyr-protocol`
• `protocol-api:zys-zephyr-protocol` reads Zephyr Scanner one-day effective APY and publishes it as `Zephyr Scanner ZYS returns`
• `zsd-zephyr-protocol` remains non-yield-bearing so the base stablecoin does not receive the wrapper's APY row

Impact notes

• `usg-tangent` now carries `yieldBearing: false`, matching Tangent's USG/sUSG split
• `usg-tangent` is removed from intentional yield-gap coverage because it is no longer part of the yield-bearing manifest universe
• The intentional-gap manifest remains reserved for assets that are actually marked yield-bearing but lack a reliable runtime APY source

Impact notes

• `susd-solayer` now has an explicit rate-derived T-bill fallback strategy in the yield manifest
• Reward-bearing account products and restricted strategy tokens without reliable public APY telemetry are not marked as runtime yield-bearing, so they do not publish misleading zero-strategy yield rows
• The active yield-bearing invariant still requires every marked asset to have a runtime strategy before it can enter live yield rankings

Impact notes

• `sUSDe`, `sUSDS`, `sDAI`, `sfrxUSD`, and `scrvUSD` now own the native runtime pool and deterministic rate readers that used to live on `USDe`, `USDS`, `DAI`, `frxUSD`, and `crvUSD`
• Those five base assets no longer advertise wrapper-owned `yieldBearing` metadata or serve the old wrapper APY series through `/api/yield-history`; the historical discontinuity is intentional and reflects corrected ownership rather than a missing backfill
• Parent-side wrapper source keys are filtered immediately at read time and purged on the hourly yield sync path, so misattributed pre-handoff rows do not linger under the base ids after rollout

Impact notes

• Cap `stcUSD`, GAIB `sAID`, Main Street `msY`, and K3 `sBOLD` are tracked as first-class yield-bearing NAV/wrapper assets rather than as native yield on cUSD, AID, msUSD, or BOLD
• `stUSDS` uses the generic on-chain ERC-4626 exchange-rate reader because the risk-capital token is distinct from Sky's plain sUSDS savings wrapper and has no standalone DeFiLlama stablecoin row
• Aave Umbrella `stkGHO` is inventoried as an intentional runtime-yield gap until a reliable reward APY source is available, avoiding a misleading zero-yield publication

Impact notes

• On-chain rows whose first observations were bootstrap `0%` APY placeholders now compute `apy7d`, `apy30d`, `excessYield`, yield stability, and PYS from real APY samples once an anchor exists
• `excessYield` remains defined as `apy30d - benchmarkRate`; detail-page and hero-chip copy now labels it as 30-day based so it is not confused with current APY spread
• Historical seed rows remain in `yield_history` for exchange-rate anchoring, but the evaluator excludes rows with `data_source='onchain'`, `exchange_rate IS NOT NULL`, `apy = 0`, and `apy_base IS NULL` from rolling stats

Impact notes

• `pusd-polaris` is now an explicit pre-launch intentional gap instead of resolving through a deterministic Silo v2 lending override
• Yield source resolution now skips configured explicit or deterministic lending candidates unless the target asset is in the active stablecoin universe
• The stablecoin metadata registry now keeps pre-launch assets in per-coin files with `status: "pre-launch"`; the legacy `shared/data/stablecoins/pre-launch.json` shell stays empty while upcoming pages and launch alerts continue to work

Impact notes

• Legacy parent-side `crvusd-curve` rows are quarantined from the generic `convertToAssets(1e18)` Tier 1 reader because that trailing 7-day delta understated Curve's current savings APY
• The new `onchain:scrvusd-curve:scrvusd-current-rate` source reads scrvUSD vault `totalSupply`, `totalAssets`, `profitUnlockingRate`, and `fullProfitUnlockDate` to compute the current daily-compounded APY
• The existing DeFiLlama scrvUSD pool remains as a curated alternative and fallback row, while source-specific history starts fresh under the new current-rate source key

Impact notes

• `usdai-usd-ai` is no longer treated as a yield-bearing wrapper host, so base USDai stops inheriting sUSDai's savings pool as its native yield source
• New tracked asset `susdai-usd-ai` now owns the existing USD.AI savings pool mapping directly, aligning yield rankings with the dedicated sUSDai detail page and nav-token semantics
• The stale USD.AI wrapper config that pointed at Arbitrum PYUSD as the `sUSDai` variant address is removed, eliminating a concrete address-level misbinding

Impact notes

• `bd-basedollar` is now classified the same way as other pre-launch yield-bearing assets with no live runtime source, so the manifest no longer reports it as a covered entry with zero strategies
• Coverage audits and operator tooling continue to inventory every yield-bearing asset, but pre-launch gaps are now fail-closed and explicit rather than implicit
• The public yield methodology docs and timeline now call out the intentional-gap treatment for these pre-launch assets

Impact notes

• For tracked stablecoins, lending-opportunity rows now require `sourceTvlUsd` and must clear `max(existing absolute floor, 0.1% of current supply)` before publication
• This applies across auto-discovered DeFiLlama lending markets, deterministic exact-pool overrides, and supplemental protocol-native lending venues
• TVL-less protocol suggestions no longer fail open into live recommendations; until venue size is observable they are omitted from published lending-opportunity coverage
• Yield methodology docs and changelog entries now document the new supply-relative recommendation gate explicitly
