https://smartcontracts.org/docs/current/references/ic-interface-spec#system-api https://github.com/dfinity/portal/blob/master/docs/references/ic-interface-spec.md

all [...](#system-api) links (total of 6) in markdown point to nowhere. I'm unsure if they should point to

• https://smartcontracts.org/docs/current/references/ic-interface-spec#canister-interface-system-api, or,
• https://smartcontracts.org/docs/current/references/ic-interface-spec#abstract-canisters-to-system-api
