ses_3848164ddffeOWQwG9A1G3TvUQBased 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. ...
