| 2 | + |
| 3 | +## Summary |
| 4 | +This PR fixes a duplication bug in `CalendarContent.addTag`, cleans up Qodana-reported issues (dangling Javadoc, missing Javadoc descriptions, fields that can be final, and safe resource usage), and adds unit tests to validate correct tag handling. |

| 46 | +## BREAKING |
| 47 | +None. |
| 48 | + |
| 49 | +## Review focus |
| 50 | +- Confirm the intention for `CalendarContent` is to accumulate tags per code without list duplication. |
| 51 | +- Sanity-check placement of `@SuppressWarnings("resource")` where resources are explicitly lifecycle-managed. |
| 52 | + |
| 53 | +## Checklist |
| 54 | +- [x] Scope ≤ 300 lines (or split/stack) |
| 55 | +- [x] Title is verb + object (Conventional Commits: `fix: ...`) |
| 56 | +- [x] Description links the issue and answers “why now?” |
| 57 | +- [x] BREAKING flagged if needed |
| 58 | +- [x] Tests/docs updated (if relevant) |
| 59 | + |
| 60 | +## Testing |
| 61 | +- ✅ `mvn -q -DskipTests package` |
| 62 | + - Build succeeded for all modules. |
| 63 | +- ✅ `mvn -q -Dtest=CalendarContentAddTagTest test` (run in `nostr-java-event`) |
| 64 | + - Tests executed successfully. New tests validate: |
| 65 | + - Two hashtags produce exactly two items without duplication. |
| 66 | + - Single participant `PubKeyTag` stored once with expected key. |
| 67 | + - Different tag types tracked independently. |
| 68 | +- ⚠️ `mvn -q verify` |
| 69 | + - Fails in this sandbox due to Mockito’s inline mock-maker requiring a Byte Buddy agent attach, which is blocked: |
| 70 | + - Excerpt: |
| 71 | + - `Could not initialize plugin: interface org.mockito.plugins.MockMaker` |
| 72 | + - `MockitoInitializationException: Could not initialize inline Byte Buddy mock maker.` |
| 73 | + - `Could not self-attach to current VM using external process` |
| 74 | + - Local runs in a non-restricted environment should pass once the agent is allowed or Mockito is configured accordingly. |
| 75 | + |
| 76 | +## Network Access |
| 77 | +- No external network calls required by these changes. |
| 78 | +- No blocked domains observed. Test failures are unrelated to network and stem from sandbox agent-attach restrictions. |
| 79 | + |
| 80 | +## Notes |
| 81 | +- `CalendarContent.addTag` previously reinserted the list and added all elements again, causing duplication. The fix uses `computeIfAbsent` and appends exactly one element. |
| 82 | +- I intentionally placed `@SuppressWarnings("resource")` where objects are long-lived or non-`AutoCloseable` (e.g., Java `HttpClient`) to silence false positives noted by Qodana. |
