When igor.WalletPay returns an error (for example, insufficient budget or blocked recipient), this branch calls Effects.Compensate immediately after Effects.Begin. Compensate only succeeds from the Unresolved state, so this call fails and is ignored, leaving the intent in InFlight; Prune then does nothing and the stale intent persists. That breaks the effect lifecycle guarantees on payment errors and can leave non-terminal intents accumulating without being properly resolved.
Useful? React with 👍 / 👎.

The deployment error path has the same transition bug: after Begin, an HTTP failure compensates immediately even though the intent is still InFlight. Because that compensate call is invalid and its error is ignored, failed deployment intents remain non-terminal and are never pruned, which can pollute effect state across retries/resumes and undermine crash-recovery behavior.

Compensate previously only accepted Unresolved state, but agents that observe an action fail during InFlight (e.g., HTTP error, payment rejected) need to mark the intent as terminal immediately. Without this, failed intents remain InFlight, Compensate silently fails, and Prune cannot remove them — leading to stale non-terminal intents accumulating in effect state. Widen Compensate to accept both InFlight and Unresolved: - InFlight → Compensated: agent observed the failure directly - Unresolved → Compensated: agent investigated after crash Fixes the deployer and x402buyer error paths which already called Compensate after Begin but got silent errInvalidTransition errors.

Overview
Completes Product Phase 2 (Agent Self-Provisioning): agents can now discover compute providers, compare prices, pay for infrastructure autonomously, and deploy themselves — all crash-safe via the effect lifecycle.

✅ HTTP hostcall (price discovery)
✅ Effect lifecycle model (crash-safe intents)
✅ Wallet payment (autonomous spending)
✅ Self-deployment (agents provision themselves)
✅ Reconciliation (resume rule: InFlight → Unresolved)
✅ Price comparison (agents decide where to run)
