The descent ladder: gate caps and tier ceilings.

The key idea

Cap versus selection

A ceiling is not a choice. The cap never picks your tier.

The single most important distinction in gate-cap doctrine: the cap is a ceiling, never a scoring input. When the account sits in Recovery, the cap says the decision engine may not resolve above T5 — it does not say the engine should resolve at T5. A Recovery week with mediocre daily EV and a cautious structural read might resolve at T2, well under the ceiling, and that's the system working correctly. Treating caps as targets is one of the classic corruption patterns: it turns a survivability constraint into an aggression prompt, and operators who 'trade to the cap' systematically over-deploy in exactly the states that exist to prevent it.

The full ladder

Seven gates, seven ceilings, one descent.

The shipped ceiling ladder: Growth permits up to T7. Recovery caps at T5. Buffer caps in the T3–T4 zone. Floor caps at T2–T3. Deep-Floor at T1–T2. Ground-Floor permits T1 only. System Lock permits nothing — no fresh deployment at all. Read as a sequence, the ceilings fall faster than the gates do: one gate step near the top can cost two tiers of ceiling. That acceleration is the ladder's message — the deeper the damage, the more disproportionate the required caution, because recovery arithmetic worsens nonlinearly with depth.

Why the steps are uneven

Some transitions are designed to be felt.

During the ladder's construction, the question was raised whether the ceilings should descend one tier per gate — a smooth staircase. The answer was no, and the reasoning became doctrine: certain gates are meant to be meaningful compression events, not mild downgrades. The entry into the containment zone should change the operator's whole posture, not shave one rung. A smooth staircase would make every transition psychologically equivalent, and they aren't — the difference between 'stability brake' and 'containment brake' is a difference in kind. The uneven steps encode severity into structure, so the ladder itself communicates how seriously each state should be taken without requiring the operator to remember.

Ceilings interact with rows

The cap and the pool row are two separate compressions.

It's worth being precise about the double mechanism. When the gate deepens, two things happen independently: the pool-budget row compresses (every tier's capital envelope shrinks), and the ceiling drops (the upper tiers become unreachable entirely). A Buffer-gate T4 is therefore doubly reduced relative to a Growth-gate T7 — it's a lower rung, priced from a tighter row. This is why deep-gate deployment is such a small fraction of peak deployment even before any structural veto is considered. The system doesn't rely on one mechanism holding; survivability is layered, and each layer would be sufficient to prevent the worst outcomes even if another slipped.

The key idea

Ceilings encode humility that no one feels at the time.

Nobody inside a −22% drawdown believes they need a T3 ceiling — belief is exactly what the drawdown has been feeding on. The ceiling ladder is the system's institutional memory of what depth does to judgment and what arithmetic does to recovery. It descends unevenly because damage compounds unevenly. And it binds because it was ratified in advance, at full strength, by the operator it now protects.
