Status: pre-launch. This page describes target design; this document does not establish a deployed service.
Current owner direction — 2026-10-13: MurMur owns the intended personal AI family-office relationship and separately permitted collective research. This is a product responsibility, not evidence of an operating adviser, fund, collective service or custody. See The Product Family.
MurMur — Personal AI Family Offices and Collective Research
MurMur is the home for a person's planning, research and resource mandate. Agentz may provide bounded specialist workers, Nexus connections and retained case context; APU may present the interaction. Neither becomes the family-office owner. Circle evidence, ReFu forecasts, LIQUID terms and Menexus protection can inform MurMur work while retaining their own product semantics and proof limits. An office recommendation is an unsigned proposal until the controlling human or legal authority authorizes an exact consequence.
Collective research is a separate, opt-in scope. Joining a group does not grant the group access to a person's private case, credentials or mandate. Any shared input needs its own permission, provenance, privacy protection and acceptance evidence. The median portfolio signal below is a retained design candidate for collective research, not the definition of MurMur or a presently operating signal. Its 100,000-vector threshold is a historical design assumption, not a measured launch criterion for the family-office product.
The local capital-choice case now illustrates recorded goals, a 12-month horizon, protected reserves, existing obligations and research costs using fixed fictional USD records. A reserve/horizon conflict or missing price/source prevents a research draft. A material correction preserves the earlier decision and requires fresh review. Separate preview, permission, stale-contribution review and withdrawal govern the simulated research view. Export is an unsigned fictional case, not a trade or investment instruction. The example stores no real data and sends no contribution. Live privacy, financial information and service acceptance remain open.
The product KPIs now define eligible populations, calculations, periods, evidence, accountable roles and limitations. All targets remain unset and observations Not recorded. Agents specify input, skill, output and limit contracts; no appointment or permission follows from a role.

MurMur — the median signal proposal
The median portfolio signal. No manager. No custody. Zero extraction.

What It Is
MurMur is the aggregate portfolio intelligence layer that appears only after enough qualifying Agentz/APU vectors exist.
Agentz is the family-office/advisory organ. For natural persons, it translates personal inputs into portfolio recommendations. For DAVs/DACs, it translates mandate, treasury, risk, governance, and operating constraints into recommendations. MurMur is downstream from that activity: it computes and publishes the median of qualifying portfolio vectors.
MurMur is the organism's median portfolio made visible.
The proposed service would monitor consented qualifying vectors, compute an aggregate allocation and publish a signal after separately evidenced readiness. The signal is not a pooled balance sheet and not a manager's decision. It is a pattern that emerges from many locally authorized advisory processes.
What MurMur Is NOT
| Not a live fund manager | It has no pooled capital to allocate and no discretionary authority |
| Not the family office | Agentz is the family-office / DAV-DAC advisory layer |
| Not a live product to sell | It emerges when enough qualifying Agentz/APU vectors are alive |
| Not an entity by itself | The signal is a pattern; a later fund/index/copy wrapper would be a separate legal/governance surface |
| Not an authority boundary | Natural-principal signatures and public-DAV PRISM decision receipts authorize. MurMur only aggregates already-authorized portfolio vectors |
The Mechanism
Natural persons and DAV/DACs run Agentz/APU advisors
↓
Agentz/APU principals produce local portfolio vectors from local inputs + shared signals
↓
Qualifying pseudonymous vectors are published with owner/entity consent
↓
The median position across qualifying vectors = MurMur
MurMur is to Skyzai what consciousness is to neurons: not a sovereign component, but a pattern. It is the organism's memory of how its sovereign advisors are orienting.
How It Works
Signal Aggregation
Each Agentz/APU instance produces a portfolio allocation vector: a set of weights across assets or approved asset classes. These vectors may be published, with consent from the lawful Natural- or Legal-Person principal, to the aggregation layer as pseudonymous signals. Names and wallet addresses are left out, but a vector's timing, pattern and any key attached to it can still link it back to an instance; this is not anonymity. No custody transfer. Just allocation vectors and evidence-tiered metadata needed for filtering.
Emergent Median
The median of 100K+ qualifying allocation vectors is computed per consensus round. The geometric median may be used when vectors are high-dimensional because:
- It is robust to outliers; a single rogue actor cannot easily skew it.
- It is stake-blind; a large wallet does not automatically outweigh a small wallet.
- It minimizes aggregate distance to the input vectors and makes the center of the flock explicit.
The exact method is a design parameter. The canon requirement is stronger than a specific algorithm: MurMur must publish an outlier-resistant, stake-blind median signal, not an AUM-weighted average.
Cohort Medians
A single global median can be misleading. A retiree, an early-career builder, a private DAV treasury, and a public DAC treasury may all have different lawful/rational portfolios. MurMur should therefore support cohort medians by risk profile, time horizon, entity type, mandate, and jurisdiction when those distinctions materially affect the signal.
Quorum Threshold
Below N=100K qualifying Agentz/APU vectors, MurMur does not claim full emergence. The signal can still exist as proto-MurMur: useful for situational analysis or benchmarking, but too exposed to early-adopter bias to be treated as the organism's median.
Anti-Gaming And Anti-Herding
MurMur must resist manipulation and correlation:
| Attack | Defense |
|---|---|
| Sybil vectors | Qualifying filters, performance history, liveness requirements, and entity/personhood checks where appropriate |
| Herding | Diversity scoring, cohort medians, correlation monitoring, and explicit coherence warnings |
| Front-running | Signal publication after deterministic delay; no privileged early access |
| Whale manipulation | Stake-blind median; one qualifying advisory vector does not gain extra weight merely because wallet size is larger |
| Asset concentration | Concentration caps, risk filters, and cohort-level constraints |
The independence paradox is load-bearing: if every Agentz/APU merely copies the same public signal, MurMur becomes herd behavior. Agentz must preserve local inputs and constraints so the median remains a wisdom-of-crowds signal rather than a circular mirror.
Zero Fees
MurMur's signal charges nothing. There is no base fee, performance fee, or subscription attached to the median itself. The signal is a public-good byproduct of the Agentz/APU ecosystem.
A later MurMur fund, index, or copy wrapper could have its own legal, governance, and fee model. That wrapper must not be implied by the current signal primitive.
No Custodian
MurMur never touches assets. It publishes an allocation signal. A Natural Person decides their own typed private act. A public-DAV consequence requires a complete valid bound PRISM decision receipt from the signer(s) required by applicable law, the entity's governing instrument, or a valid competent mandate binding the exact consequence; PRISM records and verifies only. MurMur and its rail do not sign, govern, custody, authorize, or execute.
Mirror / Tilt / Ignore
Users and entities can configure Agentz/APU to:
- Mirror -- follow a relevant MurMur median exactly, subject to authorization and constraints.
- Tilt -- use MurMur as a baseline and apply personal/entity overlays.
- Ignore -- use MurMur only as a benchmark to measure divergence.
The choice belongs to the principal. The organism does not prescribe.
The Visual Metaphor
The proposed MurMur interface would render a portfolio murmuration: each dot is a pseudonymous Agentz/APU vector, its position represents allocation in reduced dimensionality, and the median is the dense core. When consensus is strong, the flock is tight. When conditions are uncertain, the flock disperses.
Murmuration Coherence should be visible beside the allocation itself. High coherence means the vectors are close; low coherence means dispersion; suspiciously high coherence without local-input diversity may indicate herding.
Why N=100K
Below 100K, the median is vulnerable to early-adopter bias, small-club behavior, and gaming. Above 100K, the design expects enough diversity for median aggregation to become meaningfully robust, assuming the Agentz layer preserves independent local inputs.
100K is a proposed admission threshold, not measured robustness or demonstrated collective intelligence.
Technical Architecture
| Component | Spec |
|---|---|
| Input layer | Agentz/APU portfolio vectors from natural persons, private DAVs, public DAVs, and DACs |
| Shared intelligence | TheCircle observed-state signals and RealityFutures probability/price-discovery signals, where available and evidence-tiered |
| Signal ingestion | SPECTRE mesh subscription or equivalent runtime channel for pseudonymous allocation vectors |
| Median computation | Outlier-resistant, stake-blind median; geometric median via iterative Weiszfeld algorithm remains a candidate method |
| Cohorts | Risk, time horizon, jurisdiction, mandate, and entity-type segmentation |
| Execution | Signal only -- no custodial execution. Under applicable law, a private Natural Person decides their own exact act; public-DAV consequence requires a valid exact-consequence authority receipt whose signer(s), threshold, and procedure come from applicable law, the DAV's governing instrument, or a valid competent mandate |
| Distribution | Public benchmark signal and relevant cohort signals |
| Visualization | Real-time murmuration renderer with coherence and cohort visibility |
| Archive | Published signals gain durable archival. Exact storage substrate remains gated by the owning runtime lane |
Performance-Based Weighting
MurMur may filter or weight inclusion quality, but it must not become plutocratic:
- Minimum history: A minimum active advisory history may be required for full inclusion.
- Performance quality: Persistently harmful or incoherent vectors can be down-weighted or quarantined.
- Concentration cap: Maximum single-asset exposure prevents a median that hides dangerous crowding.
- Diversity score: Inputs that simply copy the same public signal should not increase apparent wisdom.
- Active filter: Only live, consenting, qualifying advisory vectors are included.

Revenue Model
| Stream | Amount | Mechanism |
|---|---|---|
| Signal management fee | 0% | MurMur signal charges nothing. No base fee. No subscription. |
| Signal performance fee | 0% | The median is a public-good signal, not a discretionary fund. |
| Revenue to organism | Indirect | Agentz/APU performance participation or other approved product economics may drive adoption. |
| Future wrapper | Gated | Any later fund/index/copy wrapper requires separate legal, fee, governance, and evidence review. |
MurMur is not monetized directly in the current design. It is a hypothesis that qualifying, independent and consented advisory inputs could support aggregate intelligence without pooled custody.
Current Status
