ses_3847fb0deffe1wcR0G2pjC5ABFYou are evaluating whether a hypothesis correctly answers a question about a coding session. Compare the hypothesis against the reference answer. Say "yes" if the hypothesis contains the key information from the reference (it can have extra detail). Say "no" if critical information is missing or wrong. Respond with ONLY "yes" or "no".
Question: What technique did the nuum gradient context manager add for tracking actual token overhead, and what two parameters does the calibrate() function take? Reference answer: The gradient added EMA (exponential moving average) calibration. The calibrate() function takes actualInput (real input tokens from the API response) and messageEstimate (the gradient's own estimate of message tokens). Hypothesis: Based on the session summary provided, the nuum gradient context manager added an EMA (Exponential Moving Average) calibration technique for tracking actual token overhead.
The calibrate() function takes two parameters:
Let me also try to use the recall tool to search for more details about this.
[assistant]: The eval is working but timing out because mode=all runs both default+nuum for all 15 questions. Let me run them separately:

done [assistant]: Done. Here's the updated summary and what we should do next. --- ## Summary **What we did:** 1. Identified 3 failure categories from the coding eval: - **Early-session detail loss** — bug fixes at message_index 1 lost during compression - **Number imprecision** — observer captured "50 entries" instead of "43 entries" by conflating event count with later table count - **Number conflict** — two valid counts (131 vs 130 test failures) with model picking the wrong one 2. **Observer prompt additions:** - `EXACT NUMBERS — NEVER APPROXIMATE`: record exact numbers from the conversation, never substitute a later count - `BUG FIXES AND CODE CHANGES — HIGH PRIORITY`: early-session code changes are just as important as later work 3. **Reflector prompt additions:** - `EXACT NUMBERS`: when segments conflict on numbers, keep the earlier/original count - `EARLY-SESSION CONTENT`: never drop early-session bug fixes during merge 4. ...
