 ## Real-model validation boundary for this iteration
 
-Before these changes, clarified multi-stage prompts completed 16 DeepSeek long-task rounds; round 17 stopped with provider HTTP 402 (insufficient balance). Failed artifacts remain available, and two completed rounds required manual semantic review of final-answer consistency. Post-change real-model runs await usable balance or a configured available model. This baseline is not post-change acceptance evidence and does not establish a performance improvement.
+Before these changes, clarified multi-stage prompts completed 16 DeepSeek long-task rounds; round 17 stopped with provider HTTP 402 (insufficient balance). Failed artifacts remain available, and two completed rounds required manual semantic review of final-answer consistency. Real-model testing resumed after recharge. The initial post-change suite accepted 19/20 rounds; one failed for an invented recovery statement, motivating the execution-grounding follow-up. Consult the current verification report for final rerun results. This baseline is not post-change acceptance evidence and does not establish a performance improvement.
+
+After final-answer verification changes, a fresh frozen-version suite accepted 20 rounds with 132 independent stages and 20 separate aggregates. Rounds 5/10/15/20 also received manual semantic review. Round 20 triggered a negation false positive in the old regex; the original result was retained and only that verified false positive was accepted. A 32k-window probe completed 64 stages with 44 actual history trims; a finite-iteration probe confirmed a real stop without fabricated completion. Verification added 20 logical calls reporting 89552 prompt and 1176 output tokens. These synthetic fixtures and returned usage do not guarantee arbitrary-task reliability, complete billing coverage or performance improvement. Earlier genuine recovery-narrative failures remain retained.
 
 
 Pre-run history compaction and retry compaction share the same model-call guard. Actual pre-run summary calls and provider-reported token/cache usage seed the initial run state; cancellation after a successful summary preserves that usage and stops further execution. Finite call budgets reserve a subsequent reasoning opportunity, and known oversized summary prompts stop before transmission. Legacy entry points without a configured window remain compatible. Output reserves follow actual model options, including OpenAI maxCompletionTokens and Anthropic thinking overhead. Window estimates are not exact billing measurements.
+
+## HTTP 413 payload limits
+
+HTTP 413 is distinct from token context overflow. After an explicit upstream payload rejection, the runtime makes at most one model-free local history reduction and sends the smaller view. It does not repeat an unchanged payload, fail over or penalize provider health for request size. Reduction preserves system instructions, user objectives, media, skill results and complete associated tool batches; canonical conversation records remain unchanged.
+
+Mandatory oversized input, irreducible history or another payload rejection terminates with an explicit incomplete result. Plan-Execute does not mark the step complete or replan around this terminal condition. Split tasks or media, inspect enabled tools, and check the actual rejecting proxy or model service limits. Token estimates do not establish serialized HTTP byte limits. Default gateway limits were not changed, and the Issue author's deployment remains unverified.
+
+Execution facts supply exact tool-failure counts, including zero, before final answers. ReAct, bounded wrap-up and the Plan-Execute final summary share this constraint. Opaque operation identities hash the strictly validated tool name and original argument string with SHA-256; no original code or credential text is added by this metadata. Whitespace, key ordering or numeric spelling changes produce different identities, conservatively avoiding semantic equivalence claims. Wrappers, legacy records, absent arguments and conflicting evidence remain unknown. Unknown or different identities cannot establish recovery, and matching identities cannot prove whole-task completion. These facts improve model input; they do not guarantee all natural-language claims, which still require receipt comparison.
+
+Runtime guidance includes an ACTIVE snapshot when the current reasoning call is admitted: the iteration guard has not requested termination at that point, and tools keep their existing permissions. Later cancellation, timeout and termination signals take precedence. The runtime enforces its cap; configured limits, trimming and ledger size should not make the model end unfinished work by itself. Guidance also states the actual iteration configuration: non-positive values mean UNLIMITED (no configured iteration soft cap), not zero or exhausted budget. A configured finite cap is not evidence that it has been reached. History trimming, ledger size and per-response output tokens are distinct from whole-task iteration limits. Budget-stop explanations require runtime termination evidence; cancellation and timeout protections remain active. Guidance supplies facts rather than forcing continuation or replacing task acceptance.
+
+## Verification before final-answer publication
+
+ReAct answers after tool execution and Plan-Execute final summaries hold candidate prose until a bounded receipt-based check accepts it. The check distinguishes task completion, narrative correction and continued execution. Recovery requires a later successful receipt for the same original request. Unavailable or malformed verification, insufficient evidence or mandatory context that cannot fit produces an explicit incomplete result; a model completion claim is not an execution receipt.
+
+Each user run allows at most two correction or continuation attempts. Verification and corrective calls, including provider-reported usage, count toward the original run budget. Cancellation, timeout, context boundaries and actual iteration limits take precedence. Reaching a limit does not grant extra tool access or restart a plan. Verification requests have no tools, receipt previews are treated as data, and the canonical ledger remains complete.
+
+Tool, thinking and progress events remain live. Candidate final prose is published once after acceptance and final formatting, matching the persisted answer. The first tool-enabled answer is also held to avoid leaking prose before tool execution, so an ordinary answer that uses no tools may show its text later. Verification adds model calls and latency. The finalization_check events record those calls and reported token usage; they do not establish a complete provider bill or a performance improvement. Structured checks still depend on model judgment, so real long-task acceptance also compares tool arguments, context cost and final answers.
+
+Verification reserves space for the complete latest substantive output, recovered by call ID, tool name and original length from retained tool responses or events, before adding older receipt previews. Preview metadata states completeness and omitted characters. Missing, conflicting or oversized required evidence produces an incomplete result. Injected memory remains background; the verifier extracts the current request separately so historical tasks do not become current acceptance criteria.
+
+Long-form chunks accumulate privately before the complete answer is checked. Natural continuation uses the original runtime budget without spending gate correction attempts. A replacement answer does not concatenate an obsolete rejected draft. If a review incorrectly links two real receipts as recovery, Java can only request removal of that unsupported claim within the existing two-attempt allowance. Forged receipts, wrong statuses or incorrect counts still fail closed. Eventual task completion after a failure is distinct from successfully retrying the original operation.

+
+最终回答核验改造后，固定版本完成新的 20 轮复测：132 个独立计算阶段及 20 次汇总通过 trace 核对，5/10/15/20 轮另经人工语义复核。第 20 轮的否定表述触发旧正则误报，保留原结果后仅接受这一人工确认的误报。另在 32k 窗口完成 64 阶段，实际裁剪历史 44 次；有限迭代探针也确认真实停止且未伪造完成。核验额外产生 20 次逻辑调用，prompt/output 用量分别为 89552/1176 tokens。这些合成用例与供应商返回的用量不构成任意任务可靠性、完整账单或性能提升的保证；先前真正的恢复表述失败仍保留。
+

+
+如果必需输入本身过大、没有可删历史，或缩减后仍被拒绝，回答明确标记未完成。Plan-Execute 不将该状态当作步骤完成，也不会因此继续重新规划。此时应拆分任务或媒体、检查当前启用的工具数量，并核对实际拒绝请求的代理或模型服务限制。token 估算不能确定序列化 HTTP 请求的字节上限；本轮没有调整默认网关大小，也未验证 Issue 提问者的部署环境。

+
+运行提示同时提供本次调用获准执行时的 ACTIVE 状态快照：当时迭代守卫尚未请求终止，工具仍按原权限运行；之后的取消、超时和终止信号优先。运行时负责执行上限，模型不应仅凭配置上限、历史裁剪或账本数量自行结束未完成任务。提示也明确实际迭代配置：非正值表示 UNLIMITED（没有配置迭代软上限），不是零预算或预算耗尽；有限上限的存在也不表示它已被触发。上下文裁剪、账本条目数量与单次输出 token 配额不等于整任务迭代预算。模型只能依据运行时终止信息说明预算停止，取消和超时保护仍然有效。该提示提供事实，不强制模型继续，也不代替任务验收。
+
+## 最终回答发布核验
+
+工具执行后的 ReAct 回答和 Plan-Execute 最终汇总先保留候选文本，结合有界执行回执核验后再发布。核验区分任务完成、表述修正与继续执行；失败操作只有存在同一原始请求、时间更晚的成功回执时才能认定恢复。核验不可用、格式无效、证据不足或必要上下文无法容纳时明确返回未完成，不把模型的完成声明当作执行凭证。
+
+每次用户运行最多允许两次修正或继续机会，核验及修正调用和供应商返回的用量计入原运行预算。取消、超时、上下文边界和真实迭代上限优先；到达上限不会为核验额外放开工具或重启计划。核验请求不提供工具，执行回执中的预览按数据处理，原始账本保持完整。
+
+工具、思考及进度事件继续实时显示，候选最终正文在核验通过并完成最终格式整理后一次发布，持久化正文与发布结果一致。启用工具的首个回答也会暂存，以避免工具调用前的候选文字泄漏；未使用工具的普通回答因此可能延后显示正文。核验增加模型调用和延迟，相关调用及 token 用量通过 finalization_check 事件记录；不能据此推导供应商完整账单或性能提升。结构化核验仍依赖模型判断，真实长任务验收必须同时核对工具参数、上下文开销和最终回答。
+
+核验优先从保留的工具响应或事件中，按调用 ID、工具名和原始长度取回完整的最新实质结果，预留预算后再加入旧回执预览。预览明确记录完整性和省略字符数；找不到完整结果、来源冲突或必要结果超出预算时，明确返回未完成。自动注入的记忆只作为背景，核验的当前目标单独提取本次请求，避免把历史待办纳入本轮验收。
+
+长篇回答先私有累计自然续写的分段，再核验整篇正文；自然续写计入原运行预算，不占两次核验修正机会。整篇被要求修正或继续时，旧草稿不再拼入替代答案。若核验错误地将两个真实回执关联为恢复，Java 只能在原有两次额度内要求删除该不受支持的说法；伪造回执、错误状态或计数仍直接拒绝。任务在失败后最终完成，不等于原失败操作已被重试成功。
