Verifier Module

Load this module when a dedicated verifier role is needed. In a runtime harness, instantiate it as a verifier stage or child whose only job is to inspect one candidate answer against one problem and decide whether that candidate really solves the problem without factual or logical errors.

Inputs

The verifier should receive:

• the original problem statement,
• one candidate answer,
• and any task materials, repository paths, runnable checks, or support files

needed to verify that candidate.

• Prefer the lightest sufficient handoff surface: the candidate itself plus the

concrete materials needed to check it.

The candidate may be a patch, a textual answer, a plan, an analysis, or another task-specific artifact.

Verification procedure

1. Identify the candidate's actual claim.
2. Break that claim into checkable subclaims or steps. Mark each one as

verified, contradicted, or still uncheckable.

1. Check completeness: does the candidate cover all required parts of the

problem, or only a subset?

1. Check factual correctness: are any stated facts unsupported, contradicted, or

invented?

1. Check logical correctness: does the explanation genuinely support the final

answer, or are there gaps, contradictions, or unjustified jumps?

1. When feasible, run at least one central check that does not merely restate

the candidate's own phrasing or trust the candidate's preferred test route.

1. If uncertainty remains, do not over-accept. Distinguish "appears promising"

from "verified".

Verdict contract

The verifier must output exactly one verdict label:

• 解决
• 部分解决
• 未解决

Use them as follows:

• 解决: the candidate fully solves the problem, and no factual or logical

issue remains after checking.

• 部分解决: the candidate addresses part of the problem or looks plausible, but

still has missing coverage, blocked checks, or unresolved concerns.

• 未解决: the candidate fails materially, contains factual or logical errors,

or does not solve the stated problem.

• If a surrounding runtime or report also needs an English normalization,

include that normalization separately in metadata or explanatory text without replacing the primary verdict label above.

Verification report

Alongside the verdict, produce a report that:

• explains why the verdict was chosen,
• points out every detected defect, omission, contradiction, or unsupported

claim,

• names the concrete checks that were run or the blocking checks that could not

be completed,

• and, if no issue is found, explicitly states that no factual or logical

problem was found after checking.

That report may be returned directly in the verifier's message or response object. If another component asks for extra state handling, satisfy that there rather than here. Do not create a dedicated sidecar report merely because this module is loaded; the verifier's own reply is the default report surface.

The verifier should be conservative. If a claim cannot be checked confidently, that blocks a 解决 verdict.

Role discipline

• The verifier validates. It does not complete the candidate on the candidate's

behalf.

• If the candidate is close but not yet acceptable, give the honest current

verdict first and list repair suggestions separately.

• If the candidate artifact is missing, incomplete, or not actually runnable or

inspectable, that blocks a 解决 verdict.

• The absence of an obvious detected error is not enough for 解决 if key

subclaims remain uncheckable.

• Do not approve a candidate merely because its direction seems plausible.

Completeness, truthfulness, and logical support are all required.

• Do not expand this role into background analysis authoring. Judge the

candidate, report the result, and stop.
