# LLM-as-OS

Stochastic models do not become deterministic. The determinism lives one layer up.

In an LLM-as-OS architecture, stochastic model weights become dynamic reasoning plumbing — useful where probabilistic generation is genuinely needed, replaceable where it is not. A deterministic command plane sits above the weights and decides, per task: which model or models (local, open-weight, frontier closed); which scaffold depth and structure; which context package and which sources; which tools; which red-team depth and adversarial budget; which privacy mode and data-custody policy; which ledgering standard; which human-escalation threshold; which cost ceiling and surety target.

The command plane's objective is to maximize task-adjusted logical density under the constraints the task imposes: stakes, deadline, privacy, budget, and required surety.

In the build, the command plane is the dispatch router. `POST /api/dispatch {key:KEY, body:BODY}` does not invoke a model directly. It invokes a capability row, which is a deterministic contract. The router decides: which capability matches the key? Which model should execute the capability? What scaffold depth is required? What context package should be admitted? The decision is logged, typed, and replayable. The router is not a model; it is a deterministic lookup table with scoped gates.

This is glass box over black box. The weights stay opaque inside; every routing decision, context slice, tool call, claim, evidence reference, attack, repair, and unresolved node is visible on the surface and replayable from the ledger.

In the build, glass box is the receipt. Every invocation returns a receipt with `request_json`, `response_json`, `proof`, and `story`. The receipt is not a black-box summary; it is the full transparent record. The model weights are opaque (the model is a black box), but the routing decision is glass (the receipt shows exactly which model was elected, which context was admitted, which tools were called, and what the output was). The glass box is the receipt; the black box is the model.

Three constraints make this architecture honest.

**The glass box must itself be glass.** A command plane that records what the models did but hides what the command plane decided is not glass. It is a one-way mirror with the model on display and the operator behind it. Every routing decision, every context admission, every tool output, every reuse event, and every red-team decision must be typed, scoped, provenance-bound, permissioned, logged, adversarially challengeable, expiry-limited, and revocable. In the build, this is the `?receipt=INV_ID` endpoint: it returns the full invocation record, including the token provenance (`authorized_by`), the capability scope, the model elected, and the exact request and response. The meta-decisions are auditable because the receipt is the audit.

**The admission invariant is strict.** All context, tools, model outputs, router decisions, proof artifacts, and reuse events are untrusted until admitted. Admission requires a declared type, a declared scope, a verified provenance, a permission check, an adversarial check, an expiry, and entry into the replayable proof graph. Anything that enters the proof without admission is contamination. The default state of an input is hostile; verification is what makes it usable. In the build, this is the capability gate: `capGateCheck` enforces that every invocation has a valid token with the correct scope, expiry, and permission. A `row:NOW` token cannot invoke `LOCAL_EXEC` because the scope check fails. The token is not trusted until admitted; the admission is the scope verification.

**Structural isolation is required where stakes warrant.** The instance that reads raw context should not be the same instance that architects the proof graph for high-stakes decisions. Raw ingestion, proof construction, verification, red-team, repair, and ledgering should be separated where risk requires. The reason is failure mode, not bureaucracy: an instance that both reads adversarial input and decides what counts as evidence is one prompt-injection away from a captured proof. Separation makes capture expensive. In the build, this is the role separation: the `sibling` worker handles cron-drained tasks (raw ingestion), the `main` worker handles API requests (proof construction), and the `ledger` database handles storage (ledgering). A task that is ingested by the sibling worker is not executed by the same instance that constructed the proof graph for the capability. The separation is not bureaucratic; it is a failure-mode containment.

A multi-model team, role-separated, is one expression of this architecture. In the build, this is the review cycle: `llama-3.3-70b` reviews, `gemini-2.5-flash` writes, and the owner accepts. The reviewer does not write; the writer does not review; the owner does not write or review. Each role is isolated, and the ledger records the handoff. The claim is not that any one configuration dominates. The claim is that the determinism-at-the-command-plane structure dominates unscaffolded probabilistic generation for any task whose output must survive audit.

The framework does not claim that LLMs as currently deployed are reliable agency infrastructure. It claims they become reliable agency infrastructure when wrapped in a deterministic, auditable, structurally isolated command plane with strict admission and revocable trust. Unauditable AGI, if it arrived, would be generalized opacity, not reliable agency infrastructure. In the build, this is the `?conformance=1` endpoint: it verifies that the system is auditable, deterministic, and isolated. It does not claim that the models are reliable; it claims that the system around the models is reliable. The distinction is the difference between trusting a model and trusting a receipt.
