The forge's contents and diffpatch endpoints take a branch, never a commit to
build on, so the parent is read from the commit the forge made, and a branch
that moved under the commit is said. Blobs are read at the commit read first,
not at the branch name. Protection rules match as Gitea 1.27 matches them
([...], {a,b}, escapes, a plain name in any case), in the Go bundle and in
guard.ts alike. One commit carries at most 4 MiB per file or patch and 16 MiB
together; code search stops at its deadline and says so. The HTTP client the
two Go bundles copied is one package, internal/forgehttp.
An agent could not get a finished change onto the forge without someone
pushing by hand, so the branch / pull request / approval rule could not be
followed. A Go bundle serves gitea_commit, held to gitea_api's rule (never the
default branch, never a protected one), and the summarised reads agents
otherwise made through gitea_api as raw JSON.
