What this model gives you

A treasury control plane combining a five-day cash ladder, haircut and FX-adjusted funding, coverage stress, operational classifications, and durable escalation rules.

What to notice

Liquidity ladders and coverage stress
Fallback-safe external FX translation
Policy classifications over named controls
Resident rules, schedules, and missed-run policy

Requirements

Async worker runtime and network access for live FX_RATE values
Resident rules runtime with persisted state
Host clock and scheduler for EVERY and AT actions

Expected checkpoint

A known state for this walkthrough.

At initial evaluation with the authored controls, before any scheduled action has fired, and after unavailable FX providers select the 1.08 EUR/USD and 1.25 GBP/USD fallbacks. The values below are source-derived and not runtime-receipted; the current contract records only provider terminal status.

Opening liquidity: 1,750,000A11
Minimum runway: 1,680,000 / 0.96F1 / F3
Stressed USD funding: 1,764,880K7, fallback-rate path
Funding cost / worst coverage: 0.050372 / 3.3165M8 / O4
Initial policy: runway-stable; funding-healthy; contained-funding; coverage-comfortable; normal-opsP1:P5

01 · Ladder

Start with cash movement, not an alert

B1:C5 describe expected inflows and outflows, D1:D5 computes daily net movement, and E1:E5 carries the balance forward. F1:F3 then expose the minimum, maximum, and runway ratio used by policy.

02 · Fund

Separate haircuts, translation, and cost

G:H applies collateral haircuts locally, J selects the effective currency factor, K translates stressed value to USD, and M prices the resulting funding. This makes a live FX change traceable without hiding the continuity fallback.

03 · Classify

Name each control decision before orchestrating it

P1:P5 independently classify runway, haircut quality, funding cost, coverage, and operating mode. Operators can inspect a single failed control instead of reverse-engineering one compound alert.

04 · Operate

Use rules only for durable operational facts

Q:R:S record escalations when their conditions become true. T1:T6 handle interval, cron, and one-shot work with explicit SKIP MISSED or BACKFILL policy; production deployments must persist their target state and scheduler ledger.
