1// verify_injection.mjs — a stranger's words are marked, and cannot reach back out.
2//
3// Two halves of one defence. Marking tells the model what it is reading; the
4// gate is what stops a model that goes along with it anyway. This drives both
5// through the REAL client: the wasm file tools for the marking, and the real
6// consent bridge, dialog and all, for the gate.
7//
8// The gate is deliberately quiet on an ordinary turn, so half these checks are
9// that NOTHING happens.
10//
11// ── A CHECK THAT COULD NOT REACH ITS OWN CONCLUSION ──────────────────
12//
13// From `023f1b2` to 2026-08-28 this file stopped at check 10 of 26, every time,
14// with "page.evaluate: Target page, context or browser has been closed" -- which
15// reads as a browser that died and was nothing of the kind. `__daimondEgressAllowed`
16// settles when the user answers, so a call that raises a dialog nobody answers never
17// settles at all, and `page.evaluate` has no deadline: the run sat there until
18// teardown, and Playwright reported the still-pending call afterwards. A hang,
19// arriving dressed as a crash.
20//
21// What raised the dialog was the check itself, on a premise `023f1b2` had removed.
22// It hand-built a payload for a host it had just had approved and expected `'allow'`
23// back, on the strength of `_egressOk` -- a per-host map in `www/js/daimond.js` that
24// lived as long as the tab. That map is gone. The answer is the CONVERSATION's now,
25// it is kept on the engine's `TurnState`, it covers every website rather than one,
26// and the page is TOLD about it in the payload's `granted` field. Asked without that
27// field, the page was right to ask, and this file had no way to answer.
28//
29// SIXTEEN CHECKS SAT BEHIND IT AND WERE NEVER RUN, and three of those were stale from
30// the same commit for the same reason: a payload address is answered in the ONE-OFF
31// words, `allow-once` and `deny-once`, so that a yes about one overlong address
32// cannot widen into the conversation's grant and a no about one cannot cut it off.
33// They were still asserting `allow` and `deny`, and nothing could see it.
34//
35// So every await of a page promise here now goes through `settle`, and a question
36// nobody answered is a FAILED CHECK naming the call rather than the end of the run.

50/// What a call answers with when it never answers at all.

57///
58/// THIS IS THE BUG THAT HID THE OTHER ONE. `__daimondEgressAllowed` returns a
59/// promise that settles when the user answers, so a call that raises a dialog
60/// nobody answers never settles -- and `page.evaluate` has no deadline. The run
61/// then sits there until the browser is torn down, at which point Playwright
62/// reports the still-pending call as "Target page, context or browser has been
63/// closed": a hang, arriving dressed as a browser that died. It stopped this
64/// file four checks short of the end, deterministically, and the four it never
65/// reached went unread for as long as it did -- three of them stale.
66///
67/// So every await of a page promise in this file goes through here. A question
68/// nobody answered is a FAILED CHECK naming the call, which is what it always
