## Useful for

- Decode the printer serial number from a document scan with deda_parse_print
- Identify which printer produced a document by comparing scans with deda_compare_prints
- Remove yellow dots from a scan or PDF before printing via deda_clean_document and deda_anonmask_apply

## Why it’s here

- Star-counter measurements on 2026-10-06 (UTC), 00:18–01:03: 2600 → 2601 stars (+1). This is the change over that interval.
- Estimated end-of-day forecast: about +11 stars, using observed gains and the previous day.
- Before this, the repository barely got any stars — about 0 per day.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 119
- Issues and pull requests: 33
- Watchers: 49
- Average over the last week: 3 per day
- Usual pace: 1 per day
- Stars in the last hour (measured): 3

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
