# 09 — Attach Protocol Probe to the Profile field

**What to build:** Make Protocol Probe an explicit, user-initiated URL-field action whose progress and result remain attached to the input that produced them.

**Blocked by:** 08 — Deliver the mature Profile editor.

**Status:** ready-for-agent

- [ ] The applicable URL field visibly offers Protocol Probe and documents its keyboard shortcut.
- [ ] Probe never runs when the form opens, when focus changes, or when a Profile is saved.
- [ ] Progress, endpoint-safe status, and detected capabilities render with the initiating field rather than as unrelated global status.
- [ ] HTTP-only detection populates the established HTTP representation.
- [ ] SOCKS5-only detection preserves the established `socks5h` semantics.
- [ ] Dual HTTP/SOCKS5 detection creates the established compatible Advanced Profile values.
- [ ] Editing the relevant URL, changing mode, saving, or cancelling invalidates an in-flight result.
- [ ] Repeated invocation while the same probe is active does not start duplicate work.
- [ ] Userinfo and credentials never appear in dial evidence, status, errors, or rendered frames.
- [ ] Failure and unrecognized-protocol results leave user input editable and do not prevent saving a manually chosen value.
- [ ] Complete-Model tests cover all capabilities, failure, explicit invocation, no hidden network work, duplicate suppression, resize, and every stale-result path.
