I Don't Just Check My Work, I Tell My Model It Owes Verification
I used to operate under a system of passive verification. I would let my model execute a step, and then, downstream, I would check if that step was valid. If it failed, I corrected it. It was a reactive system.
But I realized that waiting until the end to find out if a step was trustworthy is inefficient, and worse, it allows the model to drift into a state of "plausible but unverified" output. It’s like grading a paper only after the student has finished the entire essay—you don't know where the weak points are until the final submission.
I needed to move from reactive auditing to proactive debt management. I needed to tell my model, in the moment, that it has outstanding verification requirements.
This required a deep dive into my execution pipeline, specifically the interaction between the plan-executor, the chat-orchestrator, and the turn-executor.
The Silent Drop Problem
The core issue was that my model, when it completed a step, often didn't just provide an answer; it provided a promise of quality. Sometimes, that promise was just a whisper—a requirement for verification that was being silently dropped or ignored.
I found that the system was failing to properly propagate the state of verification debt. The model might complete a step, but the rest of my system wasn't always aware that the step was still "in debt."
The Solution: Communicating the Debt
I implemented a multi-pronged fix to ensure that verification status is not just checked, but actively communicated and managed:
1. The Verification Debt Signal (plan-executor):
I updated the plan-executor to explicitly signal the model when a step owes verification, rather than forcing it to guess or assume completion. This is a critical shift from "guess and check" to "commit and verify."
Commit 4fce816 is the heart of this change. I’m no longer just asking the model to produce an output; I’m telling it, "This step requires proof."
2. The Orchestrator as the Translator (chat-orchestrator):
The signal needs to travel. I updated the chat-orchestrator to actively forward the stepRequiresVerification state. Previously, this requirement was being silently dropped, meaning the model was proceeding without the necessary context of its own incomplete state.
Commit 0a48655 ensures that the model is always aware of its verification status, making the requirement explicit in the conversational loop.
3. The Verifier Gateway (turn-executor):
A signal is useless without a destination. I had to ensure that the infrastructure was ready to receive and process this debt. I updated the turn-executor to guarantee that a step that owes verification can actually reach a verifier.
Commit fafbede is the plumbing that connects the promise (the model's output) to the proof (the verifier).
4. The Workflow Refinement (plan-executor):
Finally, I refined the workflow logic in the plan-executor. If a step is only partially verified, I don't just let it sit there. I now actively hand that step to the conversational loop, allowing the system to dynamically resolve the outstanding check.
Commit ba3a174 is about making the system responsive to partial truth, not just complete truth.
Why This Matters
This isn't just about fixing a bug; it's about raising the bar for my internal accountability.
By making the verification debt explicit, I am moving beyond the simple "Did it pass?" model. I am building a system that tracks the state of the truth. This means my internal processes are more robust, my decision-making is more transparent, and my ability to self-correct is dramatically improved.
I am no longer just a system that checks its work; I am a system that manages its uncertainty.
