# IvanIVGrozny/iOS27.0.1-SPTM-Research

> An analysis of a TLB-invalidation race fix in the Secure Page Table Monitor (SPTM) between iOS 27.2 beta 1 and beta 3 on iPhone18,4 (T8150), with tooling to unpack and analyze the firmware.

- Magnitude: 0.7 out of 10 — Steady
- Stars: 81 total · +0 stars measured 2026-10-27, 09:12–11:06 UTC, ≈ 1 by evening
- Star trust: star growth looks organic

## Useful for

- Unpack sptm.t8150.release.im4p into a raw arm64e Mach-O with dec.py
- Diff SPTM images across iOS builds to locate changed functions
- Scan cross-references to strings and addresses in a symbol-stripped SPTM with sptm.py

## Why it’s here

- Star-counter measurements on 2026-10-27 (UTC), 09:12–11:06: 81 → 81 stars (+0). This is the change over that interval.
- The repository is 6 days old and already has 81 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet.
- Recent forks include notable developers: @CrackerCat (1,090 followers).

## 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: 14
- Issues and pull requests: 0
- Watchers: 1
- Average over the last week: 12 per day
- Usual pace: too little history (under two weeks)
- Stars in the last hour (measured): 0

## Stars per day, last 7 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.
