# bitsinfra/gnomon

> A PostgreSQL extension that brings Git-like data versioning — branches, diff, merge and undo — inside your existing database, including for AI agents.

- Magnitude: 3.4 out of 10 — Early signal
- Stars: 29 total · +2 stars measured 2026-11-14, 00:06–11:15 UTC, ≈ 11 by evening
- Star trust: star growth looks organic
- Category: Backend & databases · Language: PLpgSQL · Created: 2026-11-13 · Last push: 2026-11-14

## Useful for

- Give an agent its own database branch via a connection string so it changes data in isolation
- Review a branch diff before merging and undo a bad merge with undo_merge
- Read the database as it was at a given moment to replay what an agent saw

## Why it’s here

- Star-counter measurements on 2026-11-14 (UTC), 00:06–11:15: 27 → 29 stars (+2). This is the change over that interval.
- Estimated end-of-day forecast: about +11 stars, using observed gains and the previous day.
- The repository is 1 day old and already has 29 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet.

## 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: 0
- Issues and pull requests: 0
- Watchers: 1
- Average over the last week: 20 per day
- Usual pace: too little history (under two weeks)
- Stars in the last hour (measured): 0
- Latest release: v1.0.1 (2026-11-13)

## Stars per day, last 2 days (oldest → newest, today is partial)

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.
