Because incentives, capabilities, and information are aligned, outcomes depend entirely on synchronization: timing, sequencing, and execution under a known structure. Failure in Pure Coordination is never caused by deception, mistrust, or exploitation; it arises only from misalignment of actions or poorly designed control mechanisms. This regime represents the theoretical limit of cooperative efficiency and serves as the baseline against which all other cooperative failures are measured.
Categories of Pure Coordination
Fully Cooperative × Perfect Information × Symmetric Structure
Fixed structure (non-negotiable):
- Goals: fully aligned
- Structure: symmetric roles and capabilities
- Information: perfect, symmetric, common knowledge
- Disagreement is operational, not strategic
- The task is synchronization, not persuasion or conflict
1. Open Coordination
(Non-binding commitment)
What it is
Agents coordinate through visibility and mutual adjustment alone.
No one is locked in; coordination succeeds because the task tolerates flexibility.
How it works
- Timing is negotiated implicitly.
- Agents continuously adjust to each other.
- Success does not require irreversible action.
Why this is stable
The environment is forgiving: small delays or changes do not collapse the outcome.
Working scenarios
- Two musicians sight-reading a simple duet where tempo can flex.
- Two dancers improvising a mirrored routine with constant eye contact.
- Two engineers aligning a large schematic on a screen, adjusting position until aligned.
- Two pilots taxiing in formation under full ATC visibility.
Canonical intuition
Coordination succeeds because nothing forces premature commitment.
2. Initiative Commitment
(Unilateral binding)
What it is
One agent commits first to a timing or trajectory, creating a focal point the other coordinates around.
How it works
- One agent fixes their action.
- The other synchronizes in response.
- The task benefits from a clear initiator.
Why this is stable
The domain rewards decisive initiation; hesitation is costlier than asymmetry.
Working scenarios
- A conductor bringing in an orchestra with a downbeat.
- A lead dancer initiating choreography the partner mirrors.
- A formation leader setting pace while the second maintains alignment.
- A quarterback calling the snap count while the line reacts.
Canonical intuition
Coordination succeeds because one agent anchors timing for both.
3. Locked Synchronization
(Bilateral binding)
What it is
Both agents mutually commit to an irreversible synchronized action.
How it works
- Mutual constraint ensures simultaneity.
- Neither agent can proceed alone.
- Execution is tightly coupled.
Why this is stable
The task requires simultaneity; partial execution is meaningless.
Working scenarios
- Two astronauts executing a simultaneous EVA maneuver tethered together.
- Two surgeons performing a coordinated clamp-and-cut procedure.
- Two pilots executing a synchronized mid-air refueling maneuver.
- Two operators turning dual keys to launch a system.
Canonical intuition
Coordination succeeds because neither can act without the other.
4. Mechanical Synchronization
(Externally enforced binding)
What it is
Coordination is enforced by system design, not agent choice.
How it works
- Timing is imposed externally.
- Agents act within a locked causal structure.
- Human discretion at execution time is removed.
Why this is stable
The system guarantees simultaneity regardless of hesitation, trust, or intent.
Working scenarios
- Two robotic arms assembling a component on a shared timing bus.
- Redundant server nodes committing transactions via a synchronization protocol.
- Dual-control industrial machinery requiring simultaneous inputs.
- Flight control surfaces slaved to a central controller.
Canonical intuition
Coordination succeeds because the system does not permit desynchronization.
Structural takeaway (Pure Coordination)
This game type isolates execution certainty, not cooperation.
| Commitment expression | What enables success |
|---|---|
| Open Coordination | Flexibility and continuous adjustment |
| Initiative Commitment | Clear temporal anchor |
| Locked Synchronization | Mutual irreversibility |
| Mechanical Synchronization | Enforced simultaneity |
