+# CoreEvalProposal to replace existing price_feed and scaledPriceAuthority vats
+# with new contracts. Auctions will need to be replaced, and Vaults will need to
+# get at least a null upgrade in order to make use of the new prices. Oracle
+# operators will need to accept new invitations, and sync to the roundId (0) of
+# the new contracts in order to feed the new pipelines.
+
+The `submission` for this proposal is automatically generated during `yarn build`
+in [a3p-integration](../..) using the code in agoric-sdk through
+[build-all-submissions.sh](../../scripts/build-all-submissions.sh) and
+[build-submission.sh](../../scripts/build-submission.sh).
