Show Missing Diary Entries Without Inventing Symptom-Free Days
An empty diary cell does not mean there was no symptom. Count missing observation slots separately so a summary does not silently turn missing notes into reassuring data.
1 · diary period | planned observation slots | completed observation slots
FIRST-LOAD
Research prototype — checkout unavailable. Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Data note: Everything runs in this browser tab on the observation completeness matrix: your diary period | planned observation slots | completed observation slots stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Perspective: Before: Missing observation is different from an observed absence of symptoms. After: the observation completeness matrix shows the working beside each named row so the reader can change the assumption and inspect the consequence.

Record-completeness arithmetic only, not medical advice, diagnosis or symptom monitoring. Seek appropriate clinical help for health concerns; never delay care because a diary is incomplete.

Boundary and sources
Record-completeness arithmetic only, not medical advice, diagnosis or symptom monitoring. Seek appropriate clinical help for health concerns; never delay care because a diary is incomplete.
- Method: Missing = planned minus completed. Compare 100 × completed ÷ planned with your chosen threshold; ten of fourteen is about 71.43 percent and falls below the illustrative 80 percent target.
- All sample records are invented examples. The app does not fetch measurements, policies, files or personal records.
- Google’s official pricing page, fetched 2026-09-29, lists free-tier access including AI Studio. Optional formatting only; limits and availability can change. Free-tier content may be used to improve products. Never paste private records there.
Mechanism: competence-autonomy-loop
Optional AI formatting, not calculation
For this observation completeness matrix, use the free AI Studio interface only if available to you, with no paid API key. Manual entry completes the same workflow for free. Supply only fictional or non-sensitive notes. Review its output against the source; never paste unresolved questions into the numeric rows.
Format my non-sensitive notes for a observation completeness matrix. Return plain rows only: diary period | planned observation slots | completed observation slots. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
Accepted schema: diary period | planned observation slots | completed observation slots. No AI response is executed as code.
