A declared visibility answers the shim, and a forge's silence says which silence it was - #152

…ich silence it was Two changes to the one seam, and the second is the one that was actually reported. The shim's `public-target` scope ran `gh api repos/<owner>/<repo> --jq .visibility` on every push, including in a repository whose policy states `visibility = "private"` at the top of the file. The guard path has always read that declaration first; this seam never read it at all. It does now, for one destination only: the one `resolve_target` took from `origin` because nothing on the command line named another. A `target_flags` value is a destination somebody typed and a typed `owner/repo` carries no host, so under a `--hostname` or a `GH_HOST` the same two names are a different forge's repository with its own visibility -- and two matching path segments cannot tell those apart. Every named destination goes to the forge exactly as it did before, including the ones that name this repository. The second change is why the first was not enough. Skipping that lookup left `no-stale-visibility` to make the next call, which is correct -- it exists to catch a repository that went public while the policy still says private, and it must reach the network to do it. What was wrong was what it said when the network did not answer. `guard::names::lookup` already separated a 404 from everything else; `no_stale_visibility` then collapsed both into one message explaining what a 404 means, so an account four minutes into a rate limit read a paragraph about deleted and renamed repositories. The shim seam drew no line at all: any non-zero exit was one indistinguishable `None`. So a failed forge call is classified once, in `shim::Silence` -- NotFound, RateLimited, Refused -- and the shim seam, `no-stale-visibility` and `prevent-public-push` all read it, because three classifiers would be free to disagree about one exit code and only one of them could be right. A rate limit now names the wait, asked of `gh api rate_limit`, the one endpoint GitHub exempts from the limit it is reporting. No verdict moves. Every one of these is still exit 2, still not a pass, and still not cached -- `src/config.rs` says why, and a cache that outlives the run is a stale answer with a longer life. The point is that a reader who cannot tell a rate limit from a deleted repository reaches for `UPHOLD_ALLOW` either way. Claude-Session: https://claude.ai/code/session_01HertdiAvdNKGyjR91jvRUM

Correct the command-execution statement.
Line 1527 says that nothing is spawned. Lines 1738-1740 state that this path still runs git remote get-url origin to resolve an unnamed destination. State that no gh or forge probe runs instead.

Two changes to the one seam, and the second is the one that was actually reported.
The shim reads a declaration it already had

resolve_targettook fromoriginbecause nothing on the command line named another. Atarget_flagsvalue is a destination somebody typed, and a typedowner/repocarries no host -- so under a--hostnameor aGH_HOST,acme/widgetis a different forge's repository with its own visibility, and two matching path segments cannot tell those apart. Every named destination goes to the forge exactly as it did before, including the ones that name this repository.A silence is told apart from the other silences
Skipping that lookup left

No verdict moves. Every one of these is still exit
2, still not a pass, and still not cached.src/config.rsalready says why a cache is refused here -- "a cache that outlives the run is a stale answer with a longer life" -- and nothing in this change argues with it. The point is narrower: a reader who cannot tell a rate limit from a deleted repository reaches forUPHOLD_ALLOWeither way.Tests
cargo fmt --check,cargo clippy --all-targets -- -D warnings,cargo test-- 807 passed, 0 failed.Nine new tests. The integration ones assert the negative as well as the positive: a rate-limited push must not contain "A 404 is a private repository", and a 404 must not mention rate limiting. The declared-visibility tests use a
ghstub that writes a marker before failing, so "asked, and could not be told" and "never asked" are two states on disk rather than one exit code.https://claude.ai/code/session_01HertdiAvdNKGyjR91jvRUM
