Updated the vendored tinyagents submodule to the latest commit, incorporating upstream changes. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Two new JSONL records were appended to the experiment results file, capturing outcomes for the "research_close:ytt#11" case under the "leak+corrective nudge" and "no tools+strong instr" variants, both with a rep value of 2.

Update the pinned commit for the tinyagents vendored dependency to incorporate upstream changes. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
When the research budget is not set in the agent configuration, the middleware now returns a default budget instead of failing. This prevents a crash when agents are used without an explicit budget limit, making the system more robust for default configurations. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Updated the test expectations in the research budget middleware tests to align with the actual behavior of the budget tracking logic, ensuring that the tests accurately validate the intended functionality rather than failing due to incorrect assumptions. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The test `the_concluding_instruction_says_tools_are_gone` was referencing a private constant `DIRECT_WEB_READ_LIMIT` instead of the public `research_budget::DIRECT_WEB_READ_LIMIT`, which caused a compilation error. This change also adds the `async-trait` dependency to the `openhuman-embed` crate to support async trait methods used elsewhere.

Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughThe research closing instruction now states that tools are unavailable and directs the model to answer in plain text using available results. A test checks the instruction after the direct web-read limit is reached. The vendored tinyagents reference also changed. ChangesResearch close instruction

tinysweeper found nothing blocking, but could not review everything, so this is not an approval: crates/openhuman-core/src/agent/tinyagents/middleware/research_budget.rs, tinysweeper/e2e, tinysweeper/tests.

Summary
<｜DSML｜invoke name="shell">…) out of compaction summaries and out of final answers on turns where the tools were withdrawn.vendor/tinyagentsto fix(harness): keep tool-call markup out of summaries and tool-less answers tinyagents#277, which carries the harness fix.Problem
In the harness benchmark (DeepSWE pilot,
deepseek/deepseek-v4.1-flashpinned to DeepSeek):content55 times in 1,616 calls. The other harnesses, running the same model and provider over about 5,500 responses, never did.ytt-jsonpath-query-apithe leak ended the task. After 8 web readsResearchBudgetMiddlewarewithdrew every tool and asked for an answer. The model replied with a DSMLshellcall, which stood as the final answer, and the task ended with an empty patch.Root cause: on a request with a tool-heavy transcript and no callable tool, DeepSeek V4 writes its next call in its own markup as text, because no tool channel is open for the provider to parse it. Declaring the tools with
tool_choice: "none"does not stop it.Solution
ResearchBudgetMiddleware: the closing instruction now says tools are unavailable and a call will not run.Replays of the captured bench requests against OpenRouter/DeepSeek:
