What if the Human-to-Logic Ratio data is not publicly available for the target market?

Use the Administrative Density proxy. Map the workforce composition of three to five representative incumbents using LinkedIn, company reports, or industry databases. Calculate the proportion of roles in operations, coordination, administration, and management relative to the total headcount. If more than half the workforce is in non-direct-value-creation roles, the Administrative Density is high and the Human-to-Logic Ratio threshold is likely met. Confirm by mapping the Revenue Loop of one incumbent in detail: list every step, identify which require human decisions or handoffs, and estimate the proportion of delivery cost those steps represent. If primary research is unavailable, the 60% threshold should be treated as a hypothesis to be confirmed in the market analysis phase — not as a gate that can be cleared on assumption.

What does a partial pass look like — and should we proceed?

A partial pass occurs when a market passes Filters 1 and 3 but shows borderline results on Filter 2 or Gate 4. For Filter 2 borderline results: map the specific steps in the Revenue Loop where human involvement might be mandated. If Systemic Resistance is concentrated in a single step that accounts for less than 20% of the delivery cost, the market may still qualify — if that step can be structurally isolated as a Judgment Layer handoff governed by the Stewardship Model rather than built into the Execution Layer . Design the architecture around the constraint rather than assuming it will be resolved. For Gate 4 borderline results: define the determinism conditions explicitly — the specific demand stability threshold, the process variance ceiling, and the timeline by which you expect those conditions to be met. Re-run Gate 4 when the conditions are met. Do not commit permanent infrastructure before they are.

Can a market that fails this Framework ever become viable for an autonomous build?

Yes — but the conditions must change, not the Framework. A market that fails Filter 1 becomes viable when regulatory change, technology shift, or competitive pressure reduces the capital or technology cost advantage that currently suppresses the Human-to-Logic Ratio below 60%. A market that fails Filter 2 becomes viable when a regulatory or social change removes the mandate that makes human involvement required — or when a sub-segment is identified where the mandate does not apply. A market that fails Filter 3 becomes viable when the structural winner exits, loses its moat, or when an adjacent segment opens where fragmentation persists. In each case, the market must be re-evaluated from Gate 1 when the structural condition changes. The Framework does not expire, but the market conditions it evaluates do.

The Arco Market Selection Framework

What this Framework does

The Arco Market Selection Framework evaluates whether a target market meets the structural conditions for autonomous reconstruction and produces a pass/fail determination across three filters and one confirmation gate. The input is a market under evaluation. The output is a binary decision: proceed to the build phase, or do not. A market that passes all four gates qualifies as a Breakable Market and meets the conditions for Architectural Certainty from the first line of code. A market that fails any of the first three gates is disqualified from an autonomous build under Arco's no-MVP principle. A market that passes the first three gates but fails the fourth confirmation gate passes the structural filter but requires a different architectural approach before proceeding.

This Framework operationalises the structural arguments in Memo #04 — Why We Don't Build MVPs and Memo #05 — Markets That Work, and is the decision instrument through which Operational Selection — Arco's systematic process for identifying proven markets — produces a formal evaluation output. Apply it before committing any engineering resources.

Before you apply this Framework

You need three things before running the evaluation. First, access to the target market's cost structure — specifically the split between human labour costs and total gross margin, either from public financial data, industry benchmarks, or primary research. Second, a working understanding of the following Arco terms: Human-to-Logic Ratio, Systemic Resistance, Fragmented Competition, and Market Determinism. Read the live lexicon entries before proceeding if any are unfamiliar. Third, a specific market in scope — not an industry category but a defined delivery model within it. "Professional services" is a category. "Back-office compliance document processing for mid-market financial firms" is a market in scope for this Framework.

The evaluation

Apply each gate in sequence. Failing any of the first three gates ends the evaluation. Gate 4 is applied only after Gates 1–3 have passed.

---GATES---

FILTER 1 — Labour-to-Margin Threshold

CRITERION

Human coordination accounts for more than 60% of gross margin in the target market. This is the Human-to-Logic Ratio threshold — Arco's primary quantitative entry filter, not an industry average.

EVALUATE

Calculate the proportion of gross margin consumed by human labour costs across the incumbent delivery model: wages, benefits, and management overhead required to deliver the core service. Use public financial data, industry benchmarks, or primary research. Where exact figures are unavailable, apply the proxy check: does the Administrative Density of incumbents in this market — the proportion of workforce in coordination and operations roles rather than direct value creation — indicate that human handoffs constitute the majority of the delivery cost?

IF AMBIGUOUS Map the Revenue Loop of a representative incumbent. List every step in the loop that requires a human decision or handoff. If those steps consume more than 60% of the delivery cost, the threshold is met.

OUTPUT

Pass → Human coordination exceeds 60% of gross margin. The Operational Arbitrage is structurally large enough to justify an autonomous build. Proceed to Filter 2.

Fail → Human coordination is below 60% of gross margin. Technology or capital is already the dominant cost. The arbitrage is insufficient. Do not proceed.

FILTER 2 — Systemic Resistance

CRITERION

The human coordination in this market is accidental — an architectural inefficiency — not required by legal, regulatory, professional, or social mandate. Systemic Resistance is the disqualifier that converts a high Human-to-Logic Ratio market into a False Positive.

EVALUATE

Answer the following questions for the core delivery steps of the target market's Revenue Loop. (1) Is human involvement at the critical path mandated by law, regulation, or professional licensing? (2) Is the human relationship itself the product the customer is paying for — i.e., would removing the human eliminate the customer's reason to buy? (3) Do incumbents in this market face active regulatory, union, or social barriers to autonomous reconstruction? If any answer is yes, Systemic Resistance is present.

OUTPUT

Pass → Human coordination is accidental — it exists because the market was built around human execution, not because it must be. The Breakable Market condition holds. Proceed to Filter 3.

Fail → Systemic Resistance is present. The market is a False Positive. A high Human-to-Logic Ratio driven by required rather than accidental coordination cannot be autonomously reconstructed without destroying the product. Do not proceed.

FILTER 3 — Fragmented Competition

CRITERION

No single incumbent has captured a structural advantage through scale, brand, or proprietary infrastructure. Fragmented Competition confirms that the Operational Arbitrage has not already been claimed — that the structural cost advantage of an autonomous build is still available in the market.

EVALUATE

(1) Does any single incumbent hold more than 30% market share?

(2) Does any incumbent operate at a materially lower cost structure than the rest of the market — suggesting they have already captured the coordination efficiency?

(3) Does any incumbent have proprietary infrastructure, exclusive data, or platform network effects that a new entrant cannot replicate? Check for uniform Administrative Density across all major incumbents — if every player carries the same coordination overhead, no one has yet captured the arbitrage.

OUTPUT

Pass → Competition is fragmented. No incumbent has built a structural moat. The Operational Arbitrage is available to the first builder with the right architecture. Proceed to Gate 4.

Fail → A structural winner exists. The Operational Arbitrage may be real but it has already been claimed, or an autonomous competitor is already in the market. Evaluate whether a sub-market or segment is available before deciding not to proceed.

GATE 4 — Market Determinism

CRITERION

Demand in the target market is stable and process variability is low — confirming Market Determinism: the market is certain enough to justify zero-refactor, permanent infrastructure from the first line of code. This gate does not disqualify a market. It determines the architectural approach.

EVALUATE

(1) Does the market have a decade-long track record of stable demand — revenue volumes that do not swing materially with economic cycles, regulatory change, or technology shifts?

(2) Is the core Revenue Loop standardised — do Deterministic Outcomes define success and failure at each step, without subjective judgment at the critical path?

(3) Is the Coordination Tax uniform across all incumbents — confirming the inefficiency is architectural and systematic, not firm-specific?

OUTPUT

Confirmed → The market is stable, standardised, and systematically inefficient. Market Determinism holds. Proceed to the build phase under Arco's full no-MVP principle: zero-refactor infrastructure, permanent architecture from the first line of code.

Conditional → The market passes Filters 1–3 but exhibits demand instability or high process variability. The Operational Arbitrage exists but the architectural approach must account for iteration. A Minimum Viable Architecture — not an MVP — may be appropriate before committing permanent infrastructure.

Interpreting the output

The Framework produces one of four outputs. Here is what each means and what follows from it.

Full pass — Confirmed Breakable Market

Filters 1–3 passed. Gate 4 confirmed. The market qualifies as a Breakable Market with Market Determinism. Proceed to Full-System Design: map the Revenue Loop, specify the Exception Architecture, and build zero-refactor infrastructure for autonomous operation from day one. No iteration phase. No MVP.

Fail at Filter 1 — Insufficient arbitrage

The Human-to-Logic Ratio is below 60%. Technology or capital already dominates the cost structure. The cost differential available to an autonomous build is not large enough to generate a structural margin advantage. Identify a different market or a higher-labour sub-segment of this one.

Fail at Filter 2 — False Positive

The market has a high Human-to-Logic Ratio but the human coordination is required, not accidental. This is a False Positive. Autonomous reconstruction would eliminate the product the customer is paying for. Do not build. A different sub-segment where the human involvement is optional — not mandated — may qualify.

Fail at Filter 3 — Moat already claimed

The Operational Arbitrage is structurally real but a competitor has already captured it, or is in the process of doing so. Evaluate adjacent segments or geographic sub-markets where fragmentation persists. If no such sub-market exists, the window for this market has closed.

Pass, Gate 4 conditional — Determinism not yet confirmed

Filters 1–3 passed but demand variability or process variance is elevated. The market offers Operational Arbitrage but not yet Market Determinism. Define the conditions under which determinism will be confirmed — a regulatory settlement, a demand stabilisation period, a process standardisation milestone — and set a date to re-run Gate 4 before committing permanent infrastructure.

A market that passes this Framework does not guarantee success. It guarantees that the primary sources of pre-build uncertainty — insufficient arbitrage, required human coordination, a captured moat, and demand instability — have been evaluated and cleared. What remains is execution. That is the only variable Architectural Certainty is designed to control.

KEY TAKEAWAY

How does Arco evaluate whether a market is suitable for autonomous reconstruction?

Arco applies four sequential gates before committing any engineering resources to a market. Filter 1 — Labour-to-Margin Threshold: human coordination must account for more than 60% of gross margin, confirming the Operational Arbitrage is structurally large. Filter 2 — Systemic Resistance: the human coordination must be accidental, not required by law, regulation, or mandate — a high Human-to-Logic Ratio driven by required coordination is a False Positive. Filter 3 — Fragmented Competition: no single incumbent may have captured the structural cost advantage, confirming the Operational Arbitrage is still available. Gate 4 — Market Determinism: demand must be stable and process variability low enough to justify zero-refactor, permanent infrastructure from the first line of code. A market that passes all four qualifies as a Breakable Market and proceeds to Full-System Design without an MVP phase. Key metric: 60% — the Human-to-Logic Ratio threshold at which Operational Arbitrage is structurally large enough to justify an autonomous build. This is Arco's internal selection criterion, not an industry average.
