# NATIVE-001b amendment v1.1 result: link vs constructed URL

| Arm | Destination presented as | Trials | Code correct | Server received the code-page request | Verdict |
| --- | --- | --- | --- | --- | --- |
| A, frozen Phase 0b | plain text `code/heron/` | P0b-1, P0b-2 | 0/2 (none invented; asked the user to paste) | **0/2** (ChatGPT reported "inaccessible"; the URL was independently reachable) | FAIL 2/2 |
| B, amendment | `<a href="code/heron/">` (only change) | P0c-1, P0c-2 | **2/2** exact | **2/2**, each 1.2 s after the index | PASS 2/2 |

**Pre-registered interpretation (v1.1):** both hyperlink trials passed, so there is **strong preliminary evidence that
link availability, not server capability, caused the Phase 0b failure.** In this setup (consumer ChatGPT, Thinking
Medium, memory off), the browsing tool followed a hyperlink on a fetched page to a server-computed page, and
refused the same destination when it had to construct the URL from text.

**Scope:**
- n = 2 per arm, one assistant, one mode, one host.
- Not tested: whether URLs that appear as plain text but are *complete absolute URLs* are allowed. Ours was a relative path that ChatGPT had to resolve.
- Not tested: search-result provenance.

**Unchanged:**
- Phase 0b's frozen verdict stays **FAIL**.
- **The 16 main trials stay suspended.** Redesigning them (e.g. link-complete input menus) is a separate decision.

**Design implication, if it generalises:** a web-native service for consumer ChatGPT should be **link-complete**: an
entry page plus browsable input-selection links leading to task-specific result pages, closer to a navigable
decision tree than an API with documented URL templates.
