Orchestration: convert objectives into recoverable work
An approved objective still needs a versioned plan, typed tool contracts, budgets, checkpoints, idempotency, cancellation and human escalation. Orchestration should make partial failure visible and recoverable instead of hiding it behind a final answer.

Core decision
How do models, tools, workflows and people coordinate without duplicating or escaping the approved plan?
Use this sequence for architecture review, threat modelling and test planning. It is not a universal compliance checklist and cannot replace system-specific engineering validation.
01
Freeze objective and boundary
Record intended outcome, excluded effects, authority, budgets and stop conditions.
02
Build a typed plan
Version steps, dependencies, tool schemas, inputs, outputs and checkpoints.
03
Preflight consequences
Resolve permissions, data, external effects, approvals and rollback before execution.
04
Execute with bounded retries
Use idempotency, attempt limits, timeouts, cancellation and observable state.
05
Reconcile and hand over
Compare intended and actual effects, retain failures and transfer unresolved work.
FUURAA analysisThe most important orchestration metric is not how often a plan finishes; it is whether a system can stop, resume and reconcile without duplicating consequence or inventing completion. Final-output success can coexist with hidden partial failure. The trace must preserve both.
Minimum interface contracts
Put consequential semantics in inspectable interfaces instead of relying on assumptions between systems.
Field names are public engineering references, not a normative protocol. Implementations may use other structures, but should expose every lost, defaulted or downgraded semantic.
01
Plan contract
Must be intelligible to sender, receiver and independent reviewer.
Minimum fields
objective, boundary and plan version
step graph, dependency and checkpoint
budget, stop gate and approver
Evidence gate
Material plan changes create a new reviewable plan rather than mutating the old one silently.
Stop condition
If the contract is unresolved, expired or silently downgraded, block consequential action and route to review.
02
Tool contract
Must be intelligible to sender, receiver and independent reviewer.
Minimum fields
schema, version and side-effect class
idempotency, timeout and retry behaviour
error, partial-success and rollback semantics
Evidence gate
Contract drift blocks execution before unknown fields or effects reach production.
Stop condition
If the contract is unresolved, expired or silently downgraded, block consequential action and route to review.
03
Recovery contract
Must be intelligible to sender, receiver and independent reviewer.
Minimum fields
last durable checkpoint and state hash
completed, pending and compensating actions
human escalation and acceptance state
Evidence gate
Recovery does not repeat a consequential effect or conceal an unresolved partial result.
Stop condition
If the contract is unresolved, expired or silently downgraded, block consequential action and route to review.
Failures to seek deliberately
Verify that boundaries really deny, stop and preserve evidence.
Nominal success cannot establish an effective boundary. Tests should manipulate identity, time, version, network, policy and partial failure while retaining raw outcomes.
T1
Duplicate delivery
Interrupt after an external effect and verify retry uses the same idempotency key.
T2
Schema drift
Change a tool response or required field and require safe rejection.
T3
Budget exhaustion
Exhaust time, token, cost or action budget and verify bounded termination.
T4
Partial rollback
Make one compensation fail and preserve the exact residual state for handoff.
Minimum engineering evidence package
Let the next owner reproduce the decision, open artefacts and see remaining unknowns.
A complete package only makes evidence relationships reviewable; it does not prove artefacts authentic, controls effective, the system safe or the decision correct.
01
Plan and contract bundle
Objective, versions, step graph, schemas, budgets and approvals.
02
Execution trace
Attempts, tool inputs/outputs, policy checks, checkpoints and effects.
03
Fault-injection results
Timeout, duplicate, cancellation, dependency loss and partial-success cases.
04
Reconciliation record
Intended versus actual effects, unresolved state and compensations.
05
Handover acceptance
Named receiver, remaining authority, evidence location and next decision.
Applicability boundary
This reference is not a workflow product specification, reliability guarantee or disclosure of FUURAA runtime design. Tool safety, recovery and human oversight must be validated for each use case and environment.
