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.

lib/gitea/access.sx: repo role groups (admin>write>read) as acl facts
saturated by the datalog engine; user-owner => admin; collaborators
(per-repo role, upsert); org teams (one role, 'all' or scoped repo
list); org-admin?; visible-repos; create-allowed?; bearer tokens in kv.
Facts derived from forge state, acl db cached in the forge handle and
rebuilt only when facts change.
lib/gitea/web.sx: every repo route now requires read (404 hides private
repos); repo create needs owner/org-admin, delete + collaborator API
need admin (401 no credentials / 403 not allowed); index + /api/repos
list only visible repos; PUT/DELETE collab endpoints.
tests/access.sx (103) + repo suite updated for gating (91). Fixed a
web.sx corruption from the known sx_find_all/sx_replace_node path
mismatch by rewriting via sx_write_file; suite timeout 300->600s.
