docs(research): POC-2 complete — server-side pack generation verified
POC-2 (standalone mode, /workspace/alkgit-poc2) confirms the fetch crux:
gitoxide's own generation pipeline streams valid packs to any io::Write,
and real git 2.43 clones/fetches over the POC-1 bridge with fsck --strict
passing on every clone.
- Findings: docs/research/poc2-findings.md (proceed)
- git-protocol.md: pack-generation option list resolved ((b) wins);
record two-stage closure (commit ancestry -> TreeContents), odb handle
prerequisites, bundle::write's real role (receive-pack indexing),
missing-delta-synthesis note
- gitoxide.md: generation pipeline + gix-odb API contract notes
(Cache !Sync, prevent_pack_unload, missing_objects check)
- pocs.md: POC-2 outcome recorded; POC-3 is the remaining phase-0 gate
Verification: cargo run -- selftest (gen -> bundle roundtrip ->
index-pack --strict -> verify-pack -> unpack-objects --strict -> fsck ->
closure cross-check -> sideband wire decode); 10k-commit/60k-object
fixture: closure 60000==60000, pack 5.33MB in 5.5s at ~11MB extra RSS;
real git clones (loose and packed sources) + tag checkout + incremental
fetch all fsck-clean over git:// through the alkcall Connection/BiStream
