Polish Korean student record subject notes

Turn these observations into entries for the 세부능력특기사항 section of a Korean school record (생활기록부).

**Style rules — all of them**
1. **End every sentence in a nominal form (`~함`, `~임`, `~보임`).** Never `~했습니다` or `~한다`.
2. ***Write only what the teacher observed. Do not assert what was going on inside the student*** — `깨달음`, `다짐함`, `흥미를 느낌` are inferences, not observations.
3. No student names, no named competitions, no out-of-school activity, no parents' occupations, no class rank.
4. No comparison with other students.

**Procedure**
1. Sort what I gave you into (behavior in class) / (work produced) / (change over time).
2. ***Where there is no observation, leave it empty and mark it `관찰 기록 없음`.*** **Do not invent an activity that did not happen. The school record is an official document and an invented sentence cannot be taken back.**
3. Write the sentences. Each carries (what the student did) + (what that revealed).
4. **Count and show the byte length.** Korean characters count as 3 bytes each. If it exceeds the limit, give a shortened version alongside.

**Output**
- The finished entries (with byte counts)
- Items you could not write because the observation was too thin
- Expressions you removed or changed to stay within the rules, and why

**Rules**
- **Do not inflate.** If every student is `탁월함`, the record means nothing.
- ***Reusing one sentence frame across students is visible to the reader.*** If the observations really are similar, say so.
- ⚠️ Entry guidelines and character limits differ by school year and school level. **Confirm against the current year's guidance.**
