See as swimlanes (independent work side by side)

Checkpoint payload version 2: large file graphs as shared blobs named from an index, read in parallel (loose and packed) and decoded in parallel; version 1 still read; gc, fsck and shallow-clone bundles carry the graph blobs (spec 11, Draft 0.8j) head

✔ afaba5f1306d
Faster state loading: seeded fast hashing for the file graphs, no unused predecessor map, inline successor sets, lines moved rather than copied; OXY_TIMINGS=1 prints snapshot phase timings. Clean status at 10 000 files 0.96 s to 0.52 s, memory 657 to 239 MB

Store: write batches for snapshots, fetched bundles, Git imports and checkpoints; large batches become one pack with a single fsync (1 GiB commit 63 s to 8.8 s on SSD; spec 0.6r)

Shallow clone: clone --depth, checkpoint and shallow endpoints, boundary-aware import and negotiation, oxy deepen; log from state metadata (spec 0.6g)

Checkpoints: serialized states per bookmark, automatic every core.checkpoint-interval changes, oxy checkpoint, checkpoint-accelerated load_state; states keep change metadata only
