- Around line 358-362: Update the Gemini comparison logic around
normalized.groupName === 'bardWebModelKeys' to treat resolved geminiWebModel and
geminiWebExtendedThinking as the complete identity, excluding isCustom and
customName from generic metadata comparison. Apply the same behavior in the
session-compatible branch and return immediately after the resolved presets
match.

- Malformed later candidates are silently skipped when the candidate is non-array or has no ID. This can return an earlier completed snapshot even though a newer text snapshot was present but could not be identified; reject such populated candidates so parsing remains fail-closed.
const candidate = payload[4]?.[0]
if (!Array.isArray(candidate)) continue
const id = candidate[0]
if (id == null) continue
if (typeof id !== 'string') throw protocolError('Invalid candidate identifier.')

src/services/clients/gemini-web/protocol.mjs:33
- Google's length prefix is a UTF-8 wire-byte count, but this slices an already decoded JavaScript string by UTF-16 code units. A correctly byte-counted frame containing
台灣 😀is rejected here as truncated, so non-ASCII model metadata or answers can break parsing. Preserve/parse byte boundaries before decoding (or map the byte count back to a code-unit boundary), and update the framing test accordingly.
// Google counts the leading LF, JSON payload, and trailing LF in UTF-16 units.
const start = marker[1].length
if (!Number.isSafeInteger(length) || length <= 0 || length > RESPONSE_LIMIT) {
throw protocolError('Invalid response frame length.')
}
if (rest.length < start + length) throw protocolError('Truncated response frame.')
frame = decodeJson(rest.slice(start, start + length))
tests/unit/services/apis/gemini-web-protocol.test.mjs:37
- This test encodes the incorrect UTF-16 behavior because
wire()usespayload.length + 2. Build this Unicode frame with its UTF-8 byte length instead; the corrected fixture should pass once the parser consumes wire-byte lengths.

Copilot review overview
🔵 Needs a closer look
The undocumented live website protocol and cross-browser credential behavior require the stated browser smoke testing before approval.
Review effort: Balanced
Findings: None
Resolved since last review (5)
wire()uses…
Modernize the authenticated Gemini web path around the current website protocol, keeping it text-only and fail-closed. - Structurally parse length-framed RPC responses; validate completion, candidate identity, and continuation IDs before updating state. - Use browser credentials with bounded reads, timeout, cancellation, and stale-generation guards; never auto-retry uncertain POSTs. - Map web-history privacy to Temporary Chat; keep route-scoped continuation without stable account identity or selector support. - Replace hard-coded models with account-specific Flash-Lite, Flash, and Pro discovery, plus consumer Extended thinking and Workspace Thinking presets under the Google Gemini name. - Localize Gemini Web errors via i18n, with zh-Hant translations. - Drop the obsolete Bard adapter and unused Google-cookie read. Workspace 3.6 Thinking is a standalone web mode (mode 5), not Flash plus Extended thinking. Prefer an account-discovered mode 5 model when available, with the mode picker as a compatibility fallback; otherwise fail closed without retrying. Omit the ListAccounts/Gaia experiment. Live Firefox returned HTTP 400; Chromium uses a different account-list contract. Document the account-slot limitation (/app or /u/N) instead. Formatting, lint, tests, production build, and browser smoke tests remain merge gates. Fix ChatGPTBox-dev#723
