Root fix for the recurring class behind issue #1470. The served /install.sh and
/install.ps1 endpoints existed to hand out the unified AGENT installer, but their
GitHub fallback fetched the top-level install.sh release asset, which since
49412357a is the SERVER installer. Prior commits made that fallback unreachable
in normal deployments (deploy the sidecars; serve the local script even when
unsigned), but the endpoint was still structurally capable of serving the wrong
script in the no-local-bundle case.
The agent installer is a per-build artifact bundled into every release tarball and
Docker image, not a release asset, so the endpoint has no business proxying a
release asset at all. Remove proxyInstallScriptFromGitHub and its
installScriptReleaseAssetURL wrapper. handleDownloadInstallScriptCommon now serves
the locally bundled agent installer (signed when sidecars are present, unsigned
otherwise) or fails closed with 503 when no bundled script exists. Serving the
SERVER installer at this endpoint is now structurally impossible, not merely
unreachable.
The shared version-pinning (releaseAssetTag/releaseAssetURL) and installScriptClient
remain for the agent-BINARY download proxy, which legitimately fetches published
release assets; its version-pinning stays covered by the agentBinaryReleaseAssetURL
contract tests.
Replace the obsolete install-script proxy tests with fail-closed assertions
(including a guard that the endpoint makes no outbound call), drop the four
installScriptReleaseAssetURL contract tests, and revise the four subsystem
contracts that pinned the install-script fallback transport (api-contracts items
8 and 27, agent-lifecycle item 14, storage-recovery item 14, plus the
deployment-installability note) to state that install scripts are served local or
fail closed with no GitHub fallback.
