Artifact pages open once

A

What changed

Each page opens in the browser once. After that, the agent updates the same page and the open tab reloads itself.

Before	Now
Every render opened a new tab	First page of a session opens; later turns do not
Re-render of the same page opened it again	Same page: no new tab; the published tab reloads in place
`--open` in the rules forced a tab every turn	Rules drop `--open`; the CLI enforces open-once, `--open` included
Plan hook page + a second rendered plan page	The hook's plan page is the plan's page; no second render

B

Different page, same session

A page with a different title in the same session does not open. The agent puts its link in the reply.

Case	Opens a tab?
First page of a session	Yes
Same page again	No, the open tab reloads
New title, same session	No, link in the reply
New terminal or agent session	Yes, once
Same session after 12 hours	Yes, once
Plan approval page (plan hook)	Yes, it needs your answer

Gap closed: a run with no session variable fell back to "no session", so every new title opened. Now the terminal's tty is the key, and runs with no tty share one key.

C

How the open tab updates

If you typed a reply or comment on the page, it shows a "Page updated · Reload" button instead of reloading.

D

Bug fixed on the way

Each publish deployed only the new page and the index, so every older artifact link showed the index. Publish now keeps all pages in ~/.answer-me-with-html/published/ and deploys the whole set. 12 of 13 older pages came back from local sources. Live-artifacts-glitch-fix has no local source left.

## C How the open tab updates
```flow
Agent re-renders same title -> am publish: writes page + versions.json
am publish: writes page + versions.json -> Open tab polls versions.json every 5 s
Open tab polls versions.json every 5 s -> Reloads, keeps scroll
```
