DanConwayDev 4a7317465c fix(sync): register hydration batches before delivery
Motivation: archive startup against relay.ngit.dev discovered 50,530 remote events and paced them across 169 exact-ID REQs. The independent event processor could receive early chunks before historic_sync registered their subscription IDs and requested-event set, so valid deliveries were invisible to negentropy validation and could become an artificial missing residual. The original batch remained Syncing and prevented auxiliary tier reconciliation on the largest relay.

Approach: pre-generate the complete hydration attempt, register every subscription ID plus requested/received accounting in PendingBatch, then send each REQ with its caller-selected ID. Apply the same ordering to residual retries. A failed send removes its planned ID and definitively fails a fully drained attempt instead of leaving phantom outstanding work.

Correctness: every EVENT and terminal signal now names an ID present before the first wire request can be answered. Pre-registering all paced chunks prevents an early EOSE from draining a partially launched attempt, while the existing actor remains the sole batch confirmer. RelayConnection still acquires and releases the same generation-scoped ledger and class permits.

Excluded scope: this does not alter negentropy diffing, 300-ID chunk size, query pacing, missing-event backoff, tier admission, or connection-state eligibility.

Validation: nix develop -c cargo test --lib passed 687/687. The regression registers the production-sized 169-chunk attempt, accounts immediate deliveries, and verifies every terminal ID is attributable; the existing immediate-empty-EOSE permit test also passes.

ngit-grasp Documentation

Welcome to the ngit-grasp documentation! We use the Diátaxis framework to organize our documentation into four types, each serving a different purpose.
