FA-99926 / Agent workflow termination / Open access

Workflow: only successful turns debit the workflow budget · case 01

Failed turns leave the allowance unchanged even though every completed turn consumes budget.

Verified by executionVariant 1 · 7 checks per implementationDownload source bundle ↓JSON ↗

ROOT CAUSE

The ledger subtracts successful outcomes only.

THE FAILURE

The ledger subtracts successful outcomes only.

Unsuccessful approach: Charging only failed turns leaves successful work free.

Case contract

Return max(0, allowance - number of completed outcomes), clamped at zero.

Why this case matters

This toy decision rule isolates one bounded agent-loop completion contract.

HELD IN THE MEMBER ARCHIVE

The verified repair and its recorded checks are member-only.

This mechanism has 7 recorded checks per implementation. The open-access tier publishes the failure and the unsuccessful fix; the repaired source that passes every check, and the observations that prove it, are available to members.

Every case sharing this mechanism uses the same contract and the same repair, so this one record is held back for all of them.

Member access is invitation-based. Sign in with your invited account to inspect the repair.

Verification & scope

Each item in outcomes is one completed turn, labeled ok or error. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
