サイト踏めない事件で君から君への伝言ゲーム内容

Context:
We have been investigating a ChatGPT web-retrieval issue affecting Kaia Spec (https://www.kaiaspec.com/).

Originally, the behavior appeared account-specific:
- This ChatGPT account repeatedly failed to retrieve Kaia Spec with:
`Failed to fetch https://www.kaiaspec.com/: Cache miss`
- Another ChatGPT account could retrieve the same public site successfully.

OpenAI Support opened Case #13425847 and asked for:
- exact reproduction steps
- a screen recording showing the full process

Later, the issue partially changed:
- On the same ChatGPT account, one conversation could retrieve Kaia Spec successfully.
- Another conversation on the same account still reproduced `Cache miss`.

To make this easier for Support / Engineering to compare, we temporarily renamed the conversations:
- `CONTROL — Retrieval Success`
- `REPRO — Cache Miss`

We then captured a clean comparison set.

DAY 1 — Original failure (Aug 19, JST)
- Screenshot showing the original `Cache miss`
- HAR captured during that failure
- The DAY 1 HAR contained the actual Kaia Spec / `Cache miss` event

DAY 2 — Same account, different conversations (Aug 20, JST)
CONTROL:
- Kaia Spec retrieval succeeded
- Screenshot captured
- HAR captured

REPRO:
- Kaia Spec retrieval failed with `Cache miss`
- Screenshot captured
- HAR captured

We also recorded a screen video showing the CONTROL vs REPRO behavior in the same browser/account environment.

Important:
All HAR files prepared for submission were sanitized before sending.
Authentication/session-related material such as cookies, authorization headers, session IDs, and tokens was removed.
The original raw HAR files were retained locally in case OpenAI Engineering specifically requests them.

- REPRO_CacheMiss_case_13425847_sanitized.har
- DAY2_CONTROL_vs_REPRO_2026-08-20_JST.mp4

Because Gmail exceeded normal attachment limits, the files were provided through Google Drive with viewer access restricted to the Support recipient.

The follow-up message also stated:
If OpenAI has any difficulty accessing or downloading the files or recording, please tell us the preferred file-transfer method and we will provide the materials that way.

The amusing / important operational point:
Shamyue is not a technical engineer and does not work comfortably in English.
The entire diagnostic workflow was effectively:
- human reports what happened
- ChatGPT designs the reproduction / evidence workflow
- human follows the steps
- ChatGPT inspects the screenshots / HARs
- ChatGPT sanitizes and organizes the evidence
- human submits the finished package

So from the outside, OpenAI Support received a very clean engineering-style diagnostic package from a non-engineer user.

That is also a very Kaia Spec-shaped incident:
the affected site is a project about giving ChatGPT real work, and ChatGPT was used to diagnose its own retrieval failure and prepare the report for OpenAI.

This is probably the natural continuation point for a Garden post.
The previous Garden thread can continue from the idea:
“AI support works best when the human does not need to become the expert; the AI can translate the situation into the language the actual experts need.”
