* fix(browser): restore the Chrome-shaped browser identity (STA-7147) #18749 replaced every browser partition's Chrome-shaped UA with Electron's stock one, so since v1.4.198 the embedded browser announces itself on every non-Google host as: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Orca/1.4.198 Chrome/150.0.7871.224 Electron/43.4.1 Safari/537.36 No browser sends that. Sites that re-check the identity holding a session reject it: users report being signed out of x.com, LinkedIn and "most websites," and at least one was signed out of LinkedIn in their own Chrome and met LinkedIn's "suspicious activity" SMS check -- server-side revocation, which reaches beyond our app. The repo already documented the mechanism in browser-google-auth-ua.ts: copied-in cookies "sent under a UA that doesn't match a real first-party browser get flagged by anti-fraud." That is why the Google auth-host switch exists; #18749 kept it for accounts.google.com and handed every other host an Electron identity. Restore the pre-#18749 session identity: strip the Electron and app tokens, and rewrite sec-ch-ua to match. Nothing in the cookie-import write path changed -- it never did; cookies were always written correctly and servers were refusing them. Deliberately KEPT from #18749, all independent of the UA: - anti-detection.ts stays deleted. Its premises were measured false on Electron 43 and its overrides are themselves published bot signatures. - No Runtime.enable into cross-origin iframes (the documented Cloudflare CDP tell). - No unconditional CDP debugger attach on every browsing guest. Known tradeoff, measured: this re-opens #13822. On the unmerged predecessor branch brennan/sta-3905-cloudflare-ua, commit 9f0a4772fe recorded the stock UA clearing dash.cloudflare.com 5/5 while every rewritten variant failed 12/12, and noted that adding client hints does not rescue it. So Cloudflare-gated sites will show verification failures again until a coherent-identity fix lands. That is a bounded, in-app annoyance; session revocation damages users' real accounts. A CDP Emulation.setUserAgentOverride with full userAgentMetadata -- which drives navigator.userAgentData as well as the headers, and was never tested -- is the candidate that could satisfy both, and is being measured separately. Tests: the real-Electron wire-identity test now asserts the stripped identity on ordinary hosts and Firefox on Google auth hosts. Ablation-verified: neutering cleanElectronUserAgent turns it red on the Electron-token assertion. Its fixture also gained an app name -- without one the raw UA carried no app token, so the Orca/x.y.z half of the cleaner was never exercised. * fix(browser): finish the identity revert in the files CI caught browser-session-registry.persistence.test.ts still asserted #18749's behaviour ("keeps the stock UA", "keeps the engine UA"), so the shipped code and its test disagreed. Caught by CI shard 4/8, not locally: I reverted four test files and went to typecheck without re-running the browser suite. Also restores the accurate wording that #18749 generalised away, now that the behaviour it described is back: - browser-google-auth-ua.ts: names the Electron/Chrome-shaped UA again as what anti-fraud flags, which is the reason the auth-host switch exists at all. - docs/browser/profiles.mdx: documents the cleaned Chrome UA default and the --no-ua-spoof escape hatch, which is real again. - tests/tools/google-signin-ua-probe.cjs: comments name the live handler. Deliberately left at #18749's version, because those changes stay correct with anti-detection.ts deleted: - browser-manager-viewport.ts: its comment no longer cites the retired addScriptToEvaluateOnNewDocument injection. - browser-webauthn-profile-delete.test.ts: its added webRequest mock is REQUIRED by the restored setupClientHintsOverride, so reverting it would break the test. * fix(browser): keep restored UA hints browser-owned --------- Co-authored-by: Merge Sim <sim@local>
