* refactor(agent): ground runtime decisions in structured evidence
Use producer status and structured errors for tool recovery, preserve memory context without lexical confirmation, and remove predetermined receipt and skill conclusions.
Require explicit MCP discovery and authenticated schedule trial actions. Preserve authorization, ownership, isolation, and bounded execution; update documentation and regression coverage.
* test(sandbox): expect read_file initialization error callback
* fix(agent): address evidence review follow-ups
* fix(agent): preserve retry budgets for OpenAI transport errors
* fix(agent): expose tool execution status in model requests
Project validated execution metadata and exact tool text into request-only JSON so status survives provider serialization. Preserve stored results and receipt hashes, cover SDK and graph boundaries, and migrate replay input hashes without changing recorded responses.

* feat(harness): subagent receipt citation verification
- add receipt citation verification core
- harvest subagent tool receipts at terminal status
- transport subagent receipts and citation verdict via status contract
- verify subagent report citations at task write-back
- render citation verdicts in the delegation ledger
* fix(gateway): strip forged receipt verdicts from the delegations channel
normalize_input() and the checkpoint-state mutation sanitizer only
stripped server-owned metadata from message-shaped values, so an
external caller could submit a delegation entry carrying a forged
receipt_verdict that render_delegation_ledger would present as
runtime-owned execution evidence. Strip receipt_verdict from
caller-supplied delegation entries on both the run-creation and
thread-state mutation paths, with regression coverage for each.
* fix(harness): close silent-pass gaps in the zero-citation heuristic
The action-claim detector missed the most common completion verbs
(fixed/added/tested/changed/...) and had no CJK coverage at all, so
reports like 'I fixed the bug and added tests.' or '我已经创建了文件并运行了测试。'
were treated as claim-free: citation_resolved=True with no ledger
warning. Broaden the verb lists and add a language-independent safety
net: when the run harvested receipts and a nontrivial (>=240 char)
report cites none of them, flag it UNVERIFIED. Short claim-free
confirmations remain a vacuous pass.
