giles 83a8a2f8db sx-gitea Phase 3: wire — smart-HTTP protocol over native CIDs (TDD, 272/272) ...

lib/gitea/wire.sx: git-style pkt-line framing (byte-compatible hex4
lengths + flush sections); object closure walker (commits/trees/blobs/
tags) with missing-object detection; wants/haves pack negotiation.
Objects travel as '<cid> <serialized-sx>' pkt lines — receivers re-derive
the CID from the bytes, so packs are tamper-evident by construction.

Server endpoints: GET info/refs (read-gated advertisement incl. '@ HEAD'
symref line), POST git-upload-pack (read), POST git-receive-pack (write;
401/403/404 like the rest of the API) with per-ref command application:
create/update/delete via ref-CAS, fast-forward enforcement on heads/*,
closure-completeness check, stale detection, heads|tags-only.

Client: gitea/remote over any dream app fn — ls-remote, clone! (sets
HEAD + default-branch, cleans up on unreachable remote), mirror fetch!,
push!/push-delete! with local pack computation. Suite syncs two
in-memory forges end to end: clone, incremental fetch, push, non-ff
rejection + recovery, branch create/delete, tag push, private-repo
credentialed round trip.

sx-parse comes from spec/parser.sx on the OCaml server host — added to
the conformance load order. Also merged loops/git (git-wire export/
import adapters, 267/267) for future stock-git interop.
