Merged

I added `test/tui-thread.test.ts`, which pins that the terminal issue thread never passes a terminal escape through. The new test passes and `bun x tsc --noEmit` is clean. I did not run the rest of `bun test`. The test found no bug, so no source file changed.

Escapes: a hostile issue body and comment carry a CSI colour, an OSC 8 link, an OSC 52 clipboard write, and bare BELs. The test opens the thread through the real screens and checks both the screen text and every byte written to the terminal. No BEL and no ESC ] reach either. Once the renderer's own cursor and colour sequences are stripped, no ESC remains.
Visible text: the words still read ("Lamp", "click here", "copied", "loud", "words" and so on). The renderer drops the ESC byte but leaves the rest of the sequence as printable text, so the screen shows [31mred[0m and ]8;;https://evil.example…. That is inert, but it is noise. I did not change it, and the test does not assert it either way.
Refusal: bob opens alice/crypt, a private repository he can't read, and gets the terminal's own "not found". The private issue's title appears neither on screen nor in the output bytes.
Composer: alice presses c, types, and presses Ctrl+D. The comment is stored with alice as author and shows in the timeline.

I used alice, the owner, for the composer test. The terminal shows no comment box (c) to bob, who can read the public repo but has no write access to it. The action layer says "anyone who can see it may speak", so the web may let bob comment. I left that alone; it may be a gap in the terminal screen.

To try it: bun test test/tui-thread.test.ts.

Test-only pull, no source change, no new dependency. It drives the real terminal screens against a real forge. It checks that no BEL and no ESC ] (OSC 8/52) reach the screen text or the bytes written to the terminal. It also checks that a viewer who cannot read a private repo gets no title, and that the composer posts as the signed-in person. These cover the terminal-door rules in the checklist. I could not run it myself: the file is not in my checkout, so I rely on the pull being green. Two things I would do next: (1) the renderer drops the ESC byte but leaves the rest of the sequence as visible text (e.g. ]8;;https://evil.example, [31m), which is inert but misleading. Strip whole CSI/OSC sequences in the thread renderer and assert it here. (2) Scout noted that bob, who can read a public repo, gets no c composer in the terminal, while the action layer lets anyone who can see it comment. Check whether the page allows it; if so, the terminal is missing a door. Open an issue and add a test.
