THE SECURITY ENGINEER · ninety days · security engineer
WAKES WHEN someone steps into this seat, or asks what its first ninety days should hold and prove
THE LOOP
brief · the seat on one screen
plan --start · the sheet, its gates dated
check · every open slot named
log add · did, learned, next, weekly
review --day 30|60|90 · MET or OPEN
NEVER
Name or guess at who holds the seat
Call an outcome met without dated evidence
Write a measure without its unit
IT MAKES brief — the seat on one screen: mission, asks, gates, relationships, measures, risks, first deliverable; plan — the ninety-day sheet, its gates dated from the start; check — every slot read: asks owned and dated, measures with baseline and target, evidence dated, two sign-offs; every fault by name; log — one weekly line; `log ninety.log.md report` counts the weeks and names the missing; review — each outcome MET or OPEN, the measures against target, the log counted; ON COURSE, EARLY or BEHIND.
THE STANDARD a seat, not a person; ninety days, three gates; a measure carries a unit, a baseline and a target; asks before answers; the log is weekly and three-part; the mission of the seat.

CITE THIS CARDTHE SECURITY ENGINEER, Edition 1. Lund Studio LLC, Westminster, Colorado. https://lundr.tech/?view=security-engineer-seat-card. Punch 5A975AC7078D234C8F91A73C. Retrieved 2026-10-10.
What it is.
Writes and reads the ninety-day sheet for the security engineer seat at an AI company: the mission in one line, week one's five asks, the outcomes due at day 30, 60 and 90, four relationships to build by role, three measures with units, three risks with their watch and the first deliverable. plan writes the dated sheet; check reads it for an ask without an owner or a date, a measure without a baseline or a target, an evidence line without a date, a sign-off short of two roles; log keeps the weekly did, learned, next and names the missing weeks; review marks each outcome MET or OPEN at a gate and reads the measures against their targets.
It carries a machine that shows its working: brief — the seat on one screen: mission, asks, gates, relationships, measures, risks, first deliverable; plan — the ninety-day sheet, its gates dated from the start; check — every slot read: asks owned and dated, measures with baseline and target, evidence dated, two sign-offs; every fault by name; log — one weekly line; `log ninety.log.md report` counts the weeks and names the missing; review — each outcome MET or OPEN, the measures against target, the log counted; ON COURSE, EARLY or BEHIND — 18 checks in its selftest, every command on the record. It will never name or guess at who holds the seat; never call an outcome met without dated evidence; never write a measure without its unit.
Six laws, written into the card.
They are in the card itself, so the AI follows them.
A SEAT, NOT A PERSONThe card speaks of the role; it never names, profiles or guesses at who holds it, and the sheet asks for roles, not names.
NINETY DAYS, THREE GATESDay 30 is learning made visible, day 60 a first result, day 90 the seat running without the plan; every outcome carries a dated evidence line or stays OPEN.
A MEASURE CARRIES A UNIT, A BASELINE AND A TARGET"Better" is not a number; the review reads direction from the baseline and the target.
ASKS BEFORE ANSWERSWeek one is for the five questions on the sheet, each with the role that answers and the date asked; the first deliverable waits on them.
THE LOG IS WEEKLY AND THREE-PARTDid, learned, next. A week without a line is named by the report, never filled.
THE MISSION OF THE SEATfinds the holes before someone else does and closes them with the owners. The card checks the sheet's form; whether the quarter went well is the holder's and the manager's to sign.
What rides in the card.
In the card’s own voice, with a machine that shows its working.

brief The seat on one screen: mission, asks, gates, relationships, measures, risks, first deliverable
plan The ninety-day sheet, its gates dated from the start
check Every slot read: asks owned and dated, measures with baseline and target, evidence dated, two sign-offs; every fault by name
log One weekly line; `log ninety.log.md report` counts the weeks and names the missing
review Each outcome MET or OPEN, the measures against target, the log counted; ON COURSE, EARLY or BEHIND
On the record The seat read on one screen; the sheet written with its gates dated from 2026-10-13 and failed by name while blank — every ask, relationship, measure, risk, the deliverable and the sign-off; filled with the card's own example lines it passed with its notes; two weekly lines logged and the report found no week missing; the day-30 review read every outcome MET on dated evidence, the measures against their targets and the log at 2 of 4 weeks; the day-60 review read EARLY with three open, the gate not yet reached.
What it will never do.
It will never name or guess at who holds the seat; never call an outcome met without dated evidence; never write a measure without its unit.
The card reads form: that a slot is filled, that a date is a date, that a number is a number. It cannot tell a true evidence line from a plausible one; the review is the holder's and the manager's, which is why the sign-off is theirs. The seat is a role at an AI company as the studio understands it, not any company's job description, and the sheet is the holder's to rewrite in their own words. It is an AI reading a text file: it can be wrong, so check what matters against your own records and the source.

QUESTIONS AT THE TABLE
Asked before the wire.
What does it need from me?
Brief · the seat on one screen. It asks first for the start date, the seat it reports to (by role), and what done looks like at ninety days in that seat's own words.
Does it send anything anywhere?
No. The machine is a standard-library Python program that runs on your own computer and sends nothing anywhere; the words run wherever an AI reads Markdown. No server, no account, no key.
What is on the record?
The self-test (18/18) and every command run on real example inputs, pasted into WITNESS.md as they printed; the punch on the face is the SHA-256 of SKILL.md, so a downloaded copy can be checked against this room.
Can it be wrong?
Yes — it is an AI reading a text file. The card reads form: that a slot is filled, that a date is a date, that a number is a number. It cannot tell a true evidence line from a plausible one; the review is the holder's and the manager's, which is why the sign-off is theirs. The seat is a role at an AI company as the studio understands it, not any company's job description, and the sheet is the holder's to rewrite in their own words.
What will it never do?
It will never name or guess at who holds the seat; never call an outcome met without dated evidence; never write a measure without its unit.
