Layers of governance
Not everything earns the same scrutiny. Nothing skips it.
Governance that treats every action the same is either too slow to live with or too loose to trust. Nebbos runs four tiers — so scrutiny matches consequence — and a small set of red lines binds every tier without exception.
The idea
Scrutiny that scales with consequence.
Reading a report and rewriting the rules an organisation runs on are not the same act, and they shouldn’t pass through the same gate. Nebbos sorts every action into one of four tiers. A read-only exploration moves freely; a change to the rules an organisation runs on earns full review and a complete audit record. The weight of the check matches the weight of the move — and the consequential calls always pause for a person.
Four tiers
From read-only to rule-changing.
Alters how everything else runs
The only tier that can change the rules everything else operates under. Full review, full audit, no shortcuts. This is where a binding change actually lands.
Reasons against approved context
Drafts and proposes against an approved body of context — but it's only binding once a person promotes it through the highest tier. It can suggest; it can't quietly decide.
Routine work under standing rules
The day-to-day production work that operates inside rules already agreed. Human sign-off, kept light, so routine things don't carry outsized weight.
Looks and reports, changes nothing
Looks, reasons and reports — but changes nothing on its own. It produces findings for a person to act on, never a side effect.
The simulation gate
Rehearsed before it’s real.
Before any consequential action runs, the simulation gate forks your current operational state, runs the action forward against that private copy, checks the outcome, and throws the copy away. The real thing only ever sees a move that’s already been tested — and a person still signs off before it lands.
ALWAYS — a human on every consequential move
ALWAYS — every decision sourced and logged
ALWAYS — actions bounded to earned autonomy, and reversible
NEVER — a path that bypasses the approval gate
