The whitepaper covers SPMOS (StellarPath Memory Operating System) and its production product SPM-Polaris V3.0.0, a provider proxy with governed long-term memory for AI agents. The product promise is not “remember everything”:
When evidence is sufficient and structure allows, replace safely-removable old context with verified memory. Otherwise, forward the full original request — and leave an auditable record.
Five engineering points, each with its evidence scope:
The zero-provider-token fast path refused 23/23 unanswerable questions and hit 15/15 answerable ones. Auto (the default) pays for deep evidence collection only on ~55% of low-confidence queries, at 52–66% of deep cost. Deep keeps multi-round evidence collection for the hardest multi-hop questions.
Scope: frozen probe, 2026-08-25, two arms, reproducible from the project repository.
Once source text is persisted and retrievable, old tool output stops re-sending. Sampled production agentic sessions showed 43k–53k fewer input tokens per request (about 85% of removable tool output), with upstream response time dropping from ~2 minutes to ~35 seconds. Protected provider state, tool linkage, and thinking blocks are never touched; when safety cannot be proven, the request passes through unchanged and the receipt says so.
Scope: sampled production agentic sessions, 2026-08. Single observations, not averages or SLOs; figures include provider, tunnel, indexing, and queuing costs.
Facts consolidate into observations that present current state with history — e.g. “uses Vue (previously: React)” — with proof counts and provenance attached. Auto-captured content passes a quarantine ring and is promoted only after quality checks, so agent noise never reaches long-term memory.
Purges return signed receipts. Deleted identifiers cannot be reused within the same memory generation, so purged content cannot be revived by an old receipt.
When nothing qualifies, the system returns UNKNOWN with a machine-readable reason instead of a plausible-sounding answer. Refusals are reviewable in the console.
