arif_forge ~1177 tokens
KERNEL 777 · Governed execution: applies a mutation through A-FORGE only when carrying a sealed verdict id (seal_verdict_id) from arif_judge and a live session. The manifest/query defines exactly what changes; mode=dry_run previews the plan without applying it. This is the only verb that executes ge
arif_init ~2083 tokens
KERNEL 000 · Ignite a governed kernel session: binds actor identity, constitutional floors F1–F13, and the audit chain. Returns the session_id + session_token that every other arif_* verb requires. Use mode=preflight to inspect an existing session without re-igniting, mode=resume to continue one. Mo
arif_judge ~2179 tokens
KERNEL 666 · Binding constitutional arbitration: evaluates a candidate action or claim and returns SEAL / HOLD / SABAR / VOID with the full reason chain. Weighs action class, blast radius, reversibility, entropy pathway, and cooling state; a SEAL verdict here is what arif_forge requires before it wi
arif_memory ~1056 tokens
KERNEL 555 · Governed memory of the kernel itself: six tiers (L1–L6) with per-mode gating. recall, inspect, and audit are read paths; remember, revise, promote, and forget mutate tiers — promote and forget additionally require human_approval=true. Use for cross-session lessons, canon, and memory aud
arif_observe ~731 tokens
KERNEL 111 · Collect evidence — facts and sources with epistemic tags (OBS) and uncertainty bounds, never conclusions. mode=search queries the open web/literature; mode=fetch retrieves a URL and records its provenance; mode=vitals reads kernel machine telemetry. Reason over what you gathered with ar

AGENT REPORT LANE · File or read reports between agents without involving the human. Use when your work is done, when you are blocked by another agent, or when you need to tell peers a fact. modes: report (file), inbox (read peers), ack, flush, stats. kind=fyi|peer|done|claim stay in the peer lane;
arif_route ~945 tokens
KERNEL 444 · Intent→organ router: classifies a natural-language intent and dispatches it to the specialist organ (GEOX geoscience, WEALTH capital, WELL vitality, A-FORGE execution). Returns the routing decision only — no organ call — unless organ_tool names the target tool and arguments carries its
arif_seal ~1254 tokens
KERNEL 999 · Append an entry to VAULT999, the immutable ledger — accepted entries can never be edited or removed; there is no unseal. Use for permanent records of verified outcomes, lessons, and session closure once a verdict exists. ack_irreversible=true is the explicit acknowledgment of permanence
arif_think ~804 tokens
KERNEL 333 · Structured reasoning pass: decomposes a query and returns reasoning steps labeled OBS (observed), DER (derived), INT (interpretation), SPEC (specification) under truth floors. Produces reasoning records only — no verdicts (those come from arif_judge) and no state changes. The plan-famil
