| 21:47 | clone: byte-budgeted batches (4MB) — 159 rounds vs ~1000 for a 1M-artifact store; warm clones plant the checkpoint (first command 0.06s); print transfer/derive phases. Closes #53 check-in: c32414008b user: dmestas tags: sub-manifest | |
| 19:56 | checkpoint: accept delta manifests; anchor at newest check-in (mainline fold collapsed on real repos); sync: index the pending-delta queue (O(1) hasTarget, O(deps) completeFor) — zit now clones 2GB pkgsrc-2012 from real fossil in 10min, resumes opens in 9s vs 4min derive check-in: c70f48f825 user: dmestas tags: sub-manifest | |

checkpoint: retire the tree shape — sidecar only, structurally
The tree shape minted permanent SUBMANIFEST artifacts for benefits already had elsewhere: the rebuild win lives in the prefix record, verify's §6.2 oracle runs buildTree in memory, and the subtree-sharing bytes re-materialize at the first real S-emitting commit at identical cost. Minting early only created unreferenced permanent artifacts and the allow-tree/demotion/gate apparatus needed to keep automation from doing it by accident — all deleted with it. build no longer opens the log for writing or reads the emission settings at all; sidecar layout v3 (old sidecars miss and rebuild in seconds). Proven at scale: SHA-256 of pkgsrc's 593MB store is byte-identical across a full build; cold 4:12, rebuild 3.4s. check-in: 2a8fdcff60 user: dmestas tags: sub-manifest | |
