## Recent Decisions

| Decision | Rationale | Date |
|----------|-----------|------|
| Use n8n for orchestration | Already running on Unraid, handles Telegram webhooks | 2026-01-28 |
| Claude API for NLU | N100 can't run local LLMs fast enough | 2026-01-28 |
| Single-user auth | Simple security, only owner needs access | 2026-01-28 |
| Hardcoded user ID in workflow | n8n CE blocks env var access in expressions | 2026-01-28 |
| Silent ignore unauthorized | No false branch nodes, prevents information leak | 2026-01-28 |
| HTML parse mode | Future formatting flexibility for responses | 2026-01-28 |
| Static curl binary mount | Hardened n8n image lacks package manager | 2026-01-29 |
| --group-add 281 for socket | Node user needs docker group for socket access | 2026-01-29 |
| curl -s flag for silent mode | Prevents stderr progress output causing false errors | 2026-01-29 |
| Substring matching for containers | Simple approach works well, no external library needed | 2026-01-29 |
| HTTP 304 as success | Already-in-state is success from user perspective | 2026-01-30 |
| 10-second graceful timeout | Allows containers to shutdown cleanly before SIGKILL | 2026-01-30 |
| HTTP Request for inline keyboards | Native Telegram node has expression bug with dynamic keyboards | 2026-01-30 |
| Single-char action codes in callback | s/t/r/x encoding fits in 64-byte callback_data limit | 2026-01-30 |
| Stateless 2-min timeout | Timestamp in callback_data avoids server-side state | 2026-01-30 |
| Batch limit of 4 containers | callback_data array with 4 short IDs fits in 64 bytes | 2026-01-30 |
| Sequential batch execution | Single shell command with && chain, no n8n loops needed | 2026-01-30 |
| RESULT_N:statusCode markers | Parseable output format for aggregating batch results | 2026-01-30 |
| Silent when no update | Only notify on actual image change, not when already up-to-date | 2026-01-30 |
| Single match only for update | Update requires exact container name, no batch updates | 2026-01-30 |
| Version from OCI labels | Check org.opencontainers.image.version, then version, then ID | 2026-01-30 |
| Docker logs API with tail parameter | More efficient than fetching all logs and filtering in code | 2026-01-30 |
| Binary stream header via charCodeAt | Docker multiplexed stream uses byte 0 values 1/2, strip 8 bytes | 2026-01-30 |
| Default 50 lines, cap at 1000 | Balance between useful context and Telegram limits | 2026-01-30 |
| Truncate at 3800 chars | Telegram limit is 4096, leave room for header and formatting | 2026-01-30 |
| Remove NLU from v1.0 | Simple keyword matching sufficient, Claude API adds complexity | 2026-01-31 |
| NLU cleanup in Phase 5 | Workflow has Claude nodes to remove; defer cleanup to polish phase | 2026-01-31 |
| Keyword order matters | restart before start to avoid substring match issues | 2026-02-01 |
| No emojis on buttons | Clean button text for reliable keyword matching | 2026-02-01 |
| Terse error messages | "Failed to X Y" without HTTP codes or technical details | 2026-02-01 |
| User ID in n8n credentials | Allows workflow sharing without exposing sensitive data | 2026-02-01 |
| Text menu over keyboard | Native Telegram node replyKeyboard had issues | 2026-02-02 |
| Exact match priority | Prevents substring collisions (plex vs jellyplex) | 2026-02-02 |
| Default to :latest tag | Prevents Docker API from pulling all tags | 2026-02-02 |
| Tail pull output | Pipe through tail -c 10000 to prevent memory exhaustion | 2026-02-02 |
| HTML escape logs | Log content may contain <tag> text that breaks Telegram | 2026-02-02 |
| Notify when up-to-date | User feedback when update check finds no changes | 2026-02-02 |
