+//   - OpenHands — OPENHANDS_BUILD_GIT_SHA/_REF exists in the agent-server
+//     Dockerfile (base-image-minimal stage, added 2025-11-09 in PR #1100) but
+//     is empirically ABSENT from the runtime env of every published
+//     ghcr.io/openhands/agent-server image inspected (12+ tags, 2025-10 →
+//     2026-01, incl. the introducing PR's merge commit). The declared ENV
+//     never reaches the published image. Re-add only if a real published image
+//     carries it in `docker inspect .Config.Env`.
+//   - Aider — sets no self-identifying env var; both shell-spawn sites
+//     (run_cmd.py Popen / pexpect.spawn) pass no env=, so children inherit
+//     os.environ verbatim.
+//   - Goose — AGENT=goose/GOOSE_TERMINAL=1 are set on the recipe-retry path
+//     and the computercontroller MCP extension, but NOT on the default
+//     developer `shell` tool (sets only PATH+cwd), so the primary path is
+//     undetected.
+//   - opencode — OPENCODE_TERMINAL=1 is set only on the interactive PTY panel,
+//     not on the model's bash/shell tool.
+//   - Roo Code — ROO_ACTIVE is set only on the `vscode` terminal provider; the
+//     shipped default is the execa provider (terminalShellIntegrationDisabled
+//     defaults true), which sets no marker.
+//   - Amp / Devin / Jules / Factory Droid — no verifiable unconditional runtime
+//     marker (Amp is closed/minified; Devin/Jules are closed sandboxes;
+//     Factory's FACTORY_PROJECT_DIR / DROID_PLUGIN_ROOT are hook-scoped only).
