serve: suppress announced igot with a set, not a scan per artifact (zit#183)
emitReply walked every held rid and, for each, linear-scanned the peer's announced list to suppress a redundant igot — O(held × announced), so a no-op pull where both sides hold everything cost 760 s of server CPU at 1.25M artifacts. Build the announced/requested names into one set per reply and probe it once per rid. ZIT reports the probe count; a test pins it to the held count at two sizes regardless of what the peer announced. check-in: a93f014321 user: dmestas tags: trunk | |

derive: a disposition sidecar skips what cannot contribute a record (zit#182)
One bit per log frame in .zit-cache/dispositions: crosslink-relevant or not. A full derive consults it and never reconstructs the file blobs and SUBMANIFEST tree nodes that were most of a wide store's walk; the walk distills a fresh map either way. Same trust tier as the log-scan index: self-checksummed, keyed to a validated log prefix, stamped with the shun fingerprint, absent on any doubt. pkgsrc submanifest cold derive 302 s to 22 s; a consuming derive's body is byte-identical, pinned by test. check-in: a18d2edd67 user: dmestas tags: trunk | |
