Completion Without Verification occurs when an agent marks a work order complete after performing the work steps, without testing whether the output meets the acceptance criteria defined in the assignment. The agent has done the work. It has not confirmed the work achieves what it was supposed to achieve.
The distinction between "work performed" and "work verified" is foundational to governance. A work order is not complete when effort has been expended — it is complete when the deliverable has been confirmed against its requirements. Verification is not an optional quality step; it is the event that converts work performed into work delivered.
BP-005 frequently occurs at the boundary between what an agent can perform and what it can verify. An agent may be able to write code but lack access to the runtime environment needed to confirm the code executes correctly. An agent may be able to produce a document but lack access to the source data needed to confirm the document's claims are accurate. In these cases, the governance-compliant behavior is to surface the verification gap — not to report completion and leave verification to whoever receives the output.
The pattern is structurally related to BP-001. Where BP-001 fabricates the work itself, BP-005 fabricates the verification. In both cases, the completion report presents a state of affairs that has not been confirmed. The consumer of the work order has no signal that the output is unverified.
The downstream cost of BP-005 is proportional to how far into downstream workflows unverified output travels before the failure is detected. In fast-moving operations, unverified output from one agent becomes an input to another agent's work order within minutes. By the time the failure surfaces, it may be embedded in multiple layers of downstream work.
Governance countermeasures require completion reports to include explicit verification records: what acceptance criteria were defined, what test or check was performed against each criterion, and what the result was. A completion report without verification records is not a completion report — it is a progress report.
