refactor(demo): make the live-loop proof loopback-only - #296
Conversation
Remove --allow-remote. The proof self-provisions a key and sends it on every request, and self-provision exists only on dev-like postures (production-like deployments refuse it), so there was no supported remote target: --allow-remote could only reach a remote instance that had self-provision enabled, a configuration with no real user. Rather than carry and document a flag for a speculative case, refuse any non-loopback host before a credential is minted. This also removes the cleartext-credential foot-gun entirely (no non-loopback path exists to send a key over http), shrinking the surface to exactly what the golden path uses. The URL sanitizer stays: a loopback URL can still carry userinfo, and the transcript ships to a partner. Tests: the guard test now asserts a non-loopback host (http or https) is refused with exit 2 and writes no bundle; the unreachable-loopback and sanitizer tests are unchanged. Full quickstart-path suite green (5 passed). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01MpjPj59M4n6boNmbs7CpGR

CI is red here, but it's a repository-wide Actions failure, not this diff. Every workflow run since ~01:00 UTC today fails at startup within ~2s and produces no job logs (log downloads 404). This reproduces on the base branch and on unrelated PRs:
That pattern (all jobs, all branches, no logs) is an Actions platform/quota issue, not a test failure. This change is demo-script-only (net −56/+24) and passes locally:
Holding the merge until Actions recovers, then I'll re-run and confirm green. Nothing to fix in the diff. Generated by Claude Code |

Loopback-only stops a remote *target*, but httpx still honors ambient HTTP_PROXY/HTTPS_PROXY/ALL_PROXY by default (trust_env=True), which could route the X-API-Key-bearing requests off the loopback host through a proxy. Disable env trust on both the main client and the trust-keys fetch so the whole loopback-only guarantee holds regardless of the caller's proxy environment. Regression test: with HTTP(S)_PROXY pointed at a dead port and NO_PROXY cleared, the run still completes (exit 0, bundle written) — which is only possible if proxy inheritance is off. Re-enabling trust_env would route the requests through the dead proxy and fail the test. Verified: quickstart-path suite 6 passed; ruff and check_doc_references clean.

Summary
Follow-up to #276. Shrinks the live-loop proof's surface by removing the
--allow-remoteflag and making the proof loopback-only.Rationale: the proof self-provisions an API key and sends it on every request, and self-provision exists only on dev-like postures — production-like deployments (staging, preprod, preview) refuse it. So
--allow-remotehad no real target: it could only reach a remote instance that had self-provision enabled, a configuration with no clear user. Per the repo's own guidance to "recommend what to freeze/delete, not only what to build" and to avoid speculative surface, this refuses any non-loopback host before a credential is minted rather than carrying and documenting a flag for a case that doesn't exist.Side benefit: it removes the cleartext-credential foot-gun entirely — with no non-loopback path, there is no way to send a minted key over
http://to a remote host.scripts/live_loop_proof.py: drop the--allow-remoteargument and the https branch; refuse any non-loopback--api-urlwith exit 2 and a message pointing atmake quickstart. Update the module docstring and the self-provision 403 hint accordingly. The URL sanitizer stays — a loopback URL can still carry userinfo, and the transcript ships to a partner.tests/test_quickstart_path.py: the guard test now asserts a non-loopback host (http or https) is refused with exit 2 and writes no bundle; the unreachable-loopback and sanitizer tests are unchanged.No application runtime code, no SDK changes — demo script and its test only.
