System Architecture · Prime Directive
How MARS uses this
MARS is a closed loop, not a pipeline. Trades produce evidence, evidence produces weekly grades, grades move gate state, gate state feeds the throttle, and the throttle governs what the next execution is allowed to be. No stage is optional and no stage runs on memory or mood - each one reads the outputs of the stage before it.
How it benefits you
Discipline stops depending on willpower. Because every decision point consumes the previous stage's output, skipping a step becomes visible instead of invisible - and the system keeps improving itself, since every completed loop leaves the evidence base one cycle richer than it found it.
The MARS operating loop: execute, capture, score, gate, throttle, deploy - every cycle feeding evidence into the next.
The prime directive
The EV Lab, sensitivity tables, scenario profiles, and Monte Carlo tools are research layers. They test whether a rule change is statistically reasonable — but they never rewrite the live production system on impulse. Experimental ideas do not become live authority until validated and deliberately promoted.
Where it lives
Within System Architecture, this is one load-bearing idea — worth its own page. The parent module frames it this way: MARS is not a pile of disconnected spreadsheets — it is an engineered authority stack. Data flows forward from execution evidence to governance; permission flows downward from capital protection to trade sizing. Nothing lower in the stack can override anything above it.
The directive's cost
Keeping R&D quarantined means promising ideas wait through validation while live rules stay a version behind the frontier. The directive accepts that lag knowingly: the alternative — hot-patching production on enthusiasm — is faster exactly until the first untested change meets its first live drawdown, at which point all the saved time is repaid at interest.
