/ultrareview returns empty findings after rate limit error — burns free trial slots

Summary

/ultrareview is consuming free trial slots even when the underlying review fails due to a server-side rate limit. Both of my first two free trials returned empty findings ([]) despite a large diff that could not plausibly be clean.

Environment

• Claude Code CLI
• Command: /ultrareview (no args, reviewing current branch against main)
• Branch: kg-ultrareview-2026-04-24 → main
• Diff scope: 41 files changed, 22,439 insertions(+), 1,687 deletions(-)

Reproduction

1. Run /ultrareview on a branch with a large diff vs. main.
2. Observe "Free ultrareview X of 3" counter decrement.
3. Wait ~5–10 min for the task-notification to arrive.
4. Findings payload returns as [].

Observed Behavior

• Run 1: session_01FwYeGQ15mhZrthPqycLVdf — explicit "Server is temporarily limiting requests" / rate-limited error observed, task still marked completed, findings returned as [], free-trial counter decremented from 3 → 2.
• Run 2: session_01LugWVBs5zwqdTvDsLK29qt — same outcome, counter decremented from 2 → 1.
• No reviewer agent output, no diff coverage summary, no partial findings.

Expected Behavior

• A real review of a 22k-line diff across 41 files should surface something (style, correctness, security, or at minimum scope notes).
• When the platform rate-limits the reviewer ensemble and the review cannot complete, the run should not decrement the free-trial counter.
• Failed/empty runs should be surfaced to the user as errors, not as completed with [] findings.

Ask

1. Refund the 2 consumed trial slots on this account so I can actually use the feature.
2. Do not decrement the free-trial counter when /ultrareview fails due to a server-side error (rate limit, reviewer crash, empty payload).
3. Distinguish "review completed, nothing found" from "review failed to run" in the task-notification — currently both look identical to the user.
