The write side of the A card. add stores the blob then the attachment artifact in one commit and prints both hashes; rm ends the association with a sourceless card; list folds latest-per-(target, name). The new attachment-size-limit setting (config key 17) caps add, fossil's semantics with a 1 MiB default. A quarry attachment stub lists as external and zit artifact describes it. Smoke S15 pushes an attachment to real fossil and reads it back from fossil's attachment table. check-in: 170a2e88d0 user: dmestas tags: trunk

Once a pull finds 100 or more held artifacts no cluster names, fold them into cluster artifacts — sorted, 800 M cards each, md5 Z — at fossil's create_cluster point and thresholds. They persist with the round and extend the index; the next reply announces the clusters, not the members. A zit-born repository clusters itself the first time anyone pulls from it: 161 artifacts, one cluster, 201 bytes on the next pull. check-in: 10c905d27b user: dmestas tags: trunk

A pull or push announced every held artifact with igot, every round — 1.25M lines, ~63 MB per direction on pkgsrc. Clusters are igot in bulk: index the held clusters (.zit-cache/clusters, keyed to the log prefix, kept warm by persist), announce held minus what they name, seed the promises they made that this repository never collected, absorb pushed clusters server-side so the reply begs for their members, and honour send-catalog (full inventory) and req-clusters (enclosed cluster igots). A no-op pkgsrc pull now sends 4.7 KB. Cluster promises the peer cannot keep are a warning, not a failed pull. No format changed. check-in: e1ca72a8ef user: dmestas tags: trunk

A pull walked every held artifact in persistStore, reading each once from the lazy disk-backed holdings store just to early-return it: 194s of a 197s no-op pull at 1.25M artifacts, reconstructing nothing. Received artifacts are appended beyond the holdings' log-backed prefix, so persist now begins the walk there and processes only the received set. A no-op pull persists nothing; an incremental pull persists what it received, not the millions it already holds. No-op pkgsrc pull 209s to 7s. check-in: a25dcf28f5 user: dmestas tags: trunk
