  "account": "During a Friday merge window, five coding agents were queuing behind a single local inference process. Each request appeared insignificant, but the waiting time extended beyond an average remote round trip. A responsible colleague then sent every worker to a hosted endpoint, causing repository snippets, including a staging token, to leave the machine. The issue wasn't due to local inference itself, but rather the absence of an overflow policy that could distinguish secret-bearing context from standard code queries. When contention occurs, the local-first narrative breaks down. A local model still processes work serially due to a single generation slot exposed to every client. Frameworks mask this slot behind asynchronous wrappers, leading developers to believe requests overlap when they only enqueue. Measured time-to-first-token then incorporates all earlier jobs, making a nearby GPU seem slower than a distant server. Despite these privacy aspirations, queue depth must be treated as a primary signal rather than an afterthought. Secret-bearing prompts should not adhere to the same overflow rule as a public README query. A staging API key found in a stack trace is distinct from a question about Python itertools. The suggested workflow first classifies the payload, then checks queue depth, and finally determines if the network is accessible. Only non-secret payloads may leave the machine, provided local waiting exceeds a predetermined budget. A routing contract is proposed, which can be placed in front of any OpenAI-compatible chat endpoint. Four fields determine the lane: secret class, local queue depth, offline flag, and a wait budget in milliseconds. The router never forwards classified-secret payloads to a remote server, even when the GPU queue is severely congested. Offline machines either wait locally or fail closed, depending on the operator's policy encoded in the decision record. This report does not assert measured speedups, token quotas, or hardware ratings for any specific vendor. The numbers in the harness are placeholders to be replaced by probes from the operator's runtime. The crucial aspect is the sequence of checks, as reversing classification and overflow is how tokens leak during incidents. Teams with existing local-first agents can integrate the router without rewriting tool loops. The following Python module serves as a proposed secret-class overflow router, not a report of production measurements on a specific model. Operators must replace the secret patterns with detectors tailored to their repositories and secret scanners. The default wait budget is a placeholder, not a latency benchmark from a lab run.",

Each request looked cheap in isolation, yet the queue wait grew longer than a typical remote round trip.
