What changed
Adds an opt-in indexed-aggregate mode:
plan --indexed-aggregatespacks sub-pieces into FRC-0058 data segment aggregates,redirect-servestreams the assembled aggregate at/piece/{root}(each sub-piece hash-verified on the way out), andpdp-submitpulls that one stream and adds the root as its own single sub-piece — the 1:1 shape Curio's v0 add requires. The layout is built in pure JS (ipfs2foc-core/indexed-aggregate) from the@web3-storage/data-segmentdep, with offsets and index serialization matched against go-data-segment source. Default (bare) aggregation is unchanged.This targets the provider-side aggregate indexing being ported from Curio's mk20 pipeline into the PDPv0 path; keep on this branch until that lands and a calibration round-trip passes.
How to verify
pnpm -r typecheck && pnpm biome check . && pnpm -r test— the key tests recompute the piece commitment over the assembled bytes (unit and over real HTTP) and require it to equal the aggregate root, the same check the provider runs on pull.Notes / risks
New
indexedcolumn onaggregates(pre-release, no migration). Indexed aggregates need--source-base; the stateless relay cannot assemble the stream.
