The sx-forge native-loop blocker: clone! of the live giles/rose-ash
never returned over gitea/http-app. Root cause was NOT the transport —
pack-line-parse ran every pack line through the interpreted spec parser
(~6.6KB/s on the CEK machine; a full-repo pack = hours), and a non-hex
byte in a pkt length header parsed negative (index-of -1), walking the
scan index backwards forever.
- gitea/parse-obj: use the host reader (open-input-string + read,
~3700x faster, value-identical) when the host provides it; hosts
without string ports keep sx-parse. Feature-detected at load.
- pkt-sections-loop: (< n 4) guard — malformed lengths error instead
of hanging.
- push-cmd!: haves = every advertised remote ref held locally, so a
NEW branch pushes only its delta, not the whole repo closure.
- tests/wire.sx: malformed-len errors, truncated-pkt clamps, parse-obj
= sx-parse equivalence (blob/commit + cid). 83/83.
- tests/wire-http.sh + wire-http-client.sx: end-to-end over REAL
http-listen/http-request on :8943 — ls-remote/clone/push-new-branch/
fresh-clone-verify/delete. The coverage gap that hid all this.
Proven vs the live forge (in sx-gitea-1): full 4468-file clone in 77s
(was: hang), commit, push heads/sx-smoke-test ok, branch advertised on
sx.sx-web.org. Conformance 620/620.

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.
