Don't count empty Gemini rows as 4/4 - #73
Conversation
Failed panelist bubbles no longer inflate the vote split, and a truncated Vertex credentials JSON shows a real config error instead of "couldn't reply this round."

549-549: 🎯 Functional CorrectnessDo not parse non-OK responses for this credential error.
Invalid Vertex credentials are raised inside
runGeminiStream. The chat route catches them in the stream handler and sends an SSE{ error }event with a successful response, so line 549 does not discard this error detail.
Consensus no longer maps truncated ADC JSON to a bad-key message, later rounds ignore prior-turn replies, and Korean config-error bubbles stay out of the vote.

Later rounds only retry models that succeeded in the current round, dotenv recovery only runs for truncated "{", and voteSplit always uses the real reply count as the denominator.

There was a problem hiding this comment.
When a user continues an existing thread, discussionMessages still contains replies from earlier turns, so counting distinct senders across the entire history includes a provider that failed to answer the current turn. For example, a prior Gemini reply followed by a new user message, three successful replies, and a failed Gemini row still produces repliedCount === 4; the prompt and clamp can therefore return the exact misleading 4/4 result this change is intended to prevent.
Useful? React with 👍 / 👎.

Fixed on 69ce9e7. repliedCount is now distinct successful senders since the latest user message, so a prior-turn Gemini reply cannot make a 3-of-4 current turn show 4/4.

When the verdict model undercounts rather than overcounts, this condition leaves the incorrect denominator unchanged. With three real respondents, a generated 2/2 unanimous remains 2/2 unanimous, despite the new schema and prompt promising that the denominator is exactly the number of respondents; normalize any parsed denominator to repliedCount or reject and regenerate an inconsistent tally.

Already fixed on 2838595 (den = repliedCount). clampVoteSplit("2/2 models agree", 3) is 2/3. Skipping.

Any genuine panel response whose final sentence ends in “timed out” is classified as a failed row, not just the app-generated placeholder. This occurs naturally for debugging questions (for example, an otherwise substantive answer ending with “The upstream request timed out.”), causing that response to disappear from later-round context and consensus; match the exact provider timeout copy instead of any content with this suffix.

Fixed on 69ce9e7. Timeout rows now match only the generated placeholders (Gemini timed out., Claude timed out., etc.), not a real answer that happens to end with “timed out.”
A model that answered an earlier user message no longer inflates the denominator after it fails the current turn. Timeout placeholders match the generated copy only.

Use the failed marker for configuration errors.
These substring patterns classify any panelist reply that quotes a configuration error as failed. For example, a valid answer that explains "couldn't start:" is removed from countParticipatingModels and providersWithReplies.
Set failed: true when creating configuration-error rows and rely on that marker. Alternatively, match only the complete generated placeholder.

Failed or empty panelist replies (including Gemini's "couldn't reply this round") are dropped from the vote split, consensus prompt, and later rounds, so a 3-of-4 debate cannot show 4/4. Invalid or dotenv-truncated Vertex credentials JSON now surfaces as a real provider error instead of an empty-reply bubble.
