The daily Pixel 3 runs Casey's mainline-derived Linux 7.1.1 kernel with calls, SMS and mobile data.
Two halves · one man
Casey Tunturiarcane & algorithmic
Drag the seam between the two halves — or choose plainly.
Don’t take my word for it.
No analytics. No fingerprints. Only what you choose to leave.
The machine underneath
From kernel to cognition.
A mainline-derived Linux 7.1.1 kernel runs the phone. The operating system, lock authority, compositor, package path and agent substrate form one body with evidence and limits attached.

A mobile Linux OS composition running on real phone hardware.
The decision to lock and the presentation of a lock are separate facts.
Identity, memory, sensorium and inference live here.
Software distribution · package ownership
The path onto the body
A hand-copied binary can demonstrate an idea. It cannot demonstrate a system. Components travel through the declared package path before the operating system owns them.
- source
- candidate gate
- target build
- package
- signed archive
- pacman / updater
- package-owned device
Current boundary: the component delivery path is working; this is not yet a complete installable distribution. Producer-side manifest enforcement, ready device profiles and immutable public version releases remain open.
Same hands · different pressure
Authority and provenance recur elsewhere.
RedFlag and Statelog are separate systems. They expose the same preference for bounded power, explicit state and evidence that survives inspection.
Fleet security · public source
RedFlag
A package version waits fourteen days by default before the install path will take it.
On DNF and APT, RedFlag dry-runs the transaction, checks every pinned closure entry against OSV, and requires an Ed25519-signed, agent-bound capability before mutation. Its privileged Rust helper rechecks version, validity, identity, signature and replay state, then executes one fixed argv plan with a cleared environment. The current helper is not network-isolated; dependency hashes that cannot be resolved from signed repository metadata can be omitted. Docker, Winget and Windows Update remain on the default-strict signed-command path.
Custody and provenance · running system
Statelog
A public record that keeps evidence separate from its interpretations.
Raw responses are content-addressed and never rewritten. A new parser writes a new derivative beside the old one. An unchanged fetch still records an observation. The source and raw custody repositories remain private by design.
The live engineering record
Still moving
Reading the record…Who I am
Building since eight.
Billable IT work since high school.
I've worked as a Senior NOC tech, network engineer, field responder during major cyberattacks, and IT on yachts.
Private engagements include a 150-server ransomware recovery and zero-downtime migrations across more than 2,000 endpoints. References can corroborate the work that cannot be linked publicly. The longer career →
I'm in Hamilton, Ontario, running a homelab, and putting most of my hours into the things that matter — mobile Linux, systems that remain locally ownable, and an agent substrate that treats identity, memory and authority as engineering problems. Samaritan is where the work leaves my hands.
I wear a wizard hat. Unironically. I have a tuxedo cat and a canary and a wife who is more interesting than my LinkedIn ever was.
- On technologyTools should serve the person holding them — not extract, not surveil, not create dependency.
- On AIAn agent is not a warhorse. Presence is earned. Memory is sovereign. Choice is real.
- On the webThe free, open web is worth fighting for. Services like this should always be free and accessible.
- On bearing witnessWhen history is being made badly, someone has to write it down. That's not optional.

The archive
“The list of things I can't talk about continually is growing larger — and in tomorrow's world that's going to be evermore so.”
I've been documenting political and civil rights concerns since late 2024 at caseytunturi.com/witness — methodically, without performance, because someone has to. History written by those paying attention is different from history written after the fact.
