Quorum-Based Biological Identity Recovery

Mechanism

The recovery mechanism operates on a disrupted trust slope segment whose continuation is no longer supported by the live biological signal. The disclosed apparatus does not attempt to repair the disruption silently; it instead opens an explicit recovery transaction whose admissibility is governed by the same composite admissibility framework that governs all other identity operations on the substrate. The candidate identity presents whatever biological signal it currently produces — a partially altered face, a changed gait, a recovered cognitive baseline — and submits a recovery request that names the disrupted slope to be re-anchored.

Recovery does not proceed on the strength of the candidate signal alone. The protocol solicits independent attestations from identities holding pre-existing relational trust trajectories with the disrupted slope. Each attesting identity evaluates the candidate against its own observation lineage and emits a signed attestation that itself becomes a credentialed observation in the mesh. The attestation declares not that the candidate matches some stored template but that, to the attester's own integrated cognitive state, the candidate is continuous with the prior identity. The attestation is authored by an identity, signed under that identity's credential, and admitted only if the attester's own slope is in good standing.

A policy-defined quorum threshold governs admission. The threshold is not a bare count; it is a function of attestation quality, attester independence, and the trust depth each attester has accumulated with the disrupted slope. Two attesters with deep, long-standing relational trajectories may suffice where five shallow attesters would not. When the threshold is met within the recovery window, the apparatus emits a recovery anchor record that links the new biological observations to the disrupted slope, recording every attestation, the policy evaluation, and the resulting trust level at which the recovered slope resumes. The recovered slope does not begin at zero; it begins at a level the attestations structurally justify, and every subsequent observation accrues against that re-anchored baseline.

Operating Parameters

The recovery window is bounded. Recovery requests that remain unsatisfied past the policy-defined window expire; partial attestations collected during an expired window are retained in lineage but cease to count toward admission. The bound prevents an indefinite recovery transaction from accumulating attestations under shifting contexts and presenting a stale, opportunistic quorum at a later date. A new recovery request may be opened, but it begins a new window with its own attestation set.

Recovery invocation is rate-limited per identity, per attester, and per relational pair. A given disrupted slope may not invoke recovery more frequently than policy permits, an attester may not contribute attestations beyond a structural rate, and any one (candidate, attester) pair contributes at most one independent vote within a window. The rate limits make the protocol insensitive to flooding: an adversary cannot manufacture quorum by rapid solicitation, and a compromised attester cannot rubber-stamp a stream of recoveries.

Quality weighting governs how attestations compose. The contribution of an attestation is a function of the attester's own slope strength, the depth of the attester's prior trajectory with the disrupted slope, the recency and richness of the underlying observations, and the independence of the attester from other contributors. Independence is computed structurally: two attesters who derive their observations from a common source contribute less than two attesters with disjoint observational histories. The composite admissibility evaluator emits a quorum strength score and admits recovery only if the score crosses a policy-defined threshold that scales with the trust level being requested.

Every recovery event is permanently recorded in the identity lineage as a first-class anchor. The lineage records the disrupted slope, the candidate biological signal, every attestation and its signing credential, the policy under which admission was evaluated, the quorum strength score, the recovery window, the resulting re-anchor level, and the credentialing authority of the protocol invocation. Subsequent operations on the recovered slope reference this anchor; downstream relying parties may inspect the lineage and apply their own additional risk policy on top of the protocol's admission decision.

Alternative Embodiments

The protocol admits embodiments differing in how attestations are gathered, weighted, and combined. In a synchronous embodiment, the candidate appears in a session with attesters and the attestations are collected over a short interval. In an asynchronous embodiment, the recovery request is broadcast to qualifying attesters and attestations accumulate over the recovery window as attesters become available; the candidate need not be co-present with the attesters. The two embodiments are interoperable; a single recovery transaction may mix synchronous and asynchronous attestations under common quorum policy.

Embodiments differ in the structure of the quorum requirement. A simple threshold embodiment admits recovery once a fixed number of qualifying attesters have signed. A weighted threshold embodiment admits recovery when the sum of attestation weights exceeds a policy threshold. A multi-tier embodiment requires representation from disjoint trust communities, so that recovery cannot be effected by a single tightly-coupled cluster of attesters. Hybrid embodiments combine these structures: a weighted sum gated by a multi-tier independence requirement.

Embodiments differ in how the recovered slope resumes. In a fresh-anchor embodiment, the recovered slope begins at a trust level derived purely from the quorum strength, decoupled from the disrupted slope's prior level. In a continuation embodiment, the recovered slope inherits a discounted form of the disrupted slope's prior level, with the discount scaling as a function of the disruption magnitude and recovery quality. In a probationary embodiment, the recovered slope begins at a reduced level and accrues toward its prior level only after a policy-defined observation period in which the substrate behaves consistently with the attested identity.

Embodiments differ in their treatment of partial recoveries. Where a quorum is not met but a substantial subset of attestations is collected, the apparatus may admit a limited recovered slope sufficient for low-stakes operations while withholding admission for high-stakes operations until additional attestations are gathered. The graduated admission reflects that recovery is not a binary state but a confidence gradient over the substrate's identity claim.

Composition With Other Subsystems

Quorum recovery composes with the trust slope subsystem by treating recovery as a slope event rather than as a separate identity-replacement operation. The recovery anchor is a node on the same lineage as ordinary observations; downstream slope analytics see continuity through the disruption, with the recovery anchor marked as a distinguished event. Trust decay, slope strengthening, and slope branching all operate on the recovered slope as they would on any slope.

Quorum recovery composes with the relational trajectory subsystem by drawing its attesters from existing relational counterparts. The trajectories with attesters are themselves preserved across the recovery, because the attestations are emitted from those very trajectories; the recovery does not invalidate prior relationships, it leverages them as the substrate of trust on which restoration is grounded.

Quorum recovery composes with the cognitive state subsystem by admitting cognitive observations as inputs to the attestation decision. An attester whose cognitive state indicates impaired evaluation contributes less weight, and an attester whose cognitive observations of the candidate indicate substantive familiarity contributes more. The cognitive state subsystem also gates whether a particular candidate may even initiate a recovery: a candidate exhibiting cognitive states inconsistent with the prior slope's trajectory may be required to satisfy a higher threshold or wait through a stabilization window.

Quorum recovery composes with the governed actuation subsystem by emitting recovery events as credentialed observations admissible to actuators. An actuator whose admissibility policy requires identity continuity may continue to act on a recovered slope without manual intervention, because the recovery anchor satisfies the continuity requirement. The actuator's own audit lineage records that it acted on a recovered slope and references the recovery anchor.

Prior-Art Distinctions

Account-recovery mechanisms in conventional identity systems treat recovery as a credential reset: a sufficiently authenticated request causes the system to issue new credentials bound to a stable account record. The biological identity context has no stable account record. The identity is the trust slope; there is nothing outside the slope to which a new credential can be bound. Conventional recovery primitives therefore do not apply.

Threshold cryptography schemes implement quorum as a secret-sharing property: M-of-N parties cooperate to reconstruct a secret. The disclosed apparatus does not reconstruct a secret. It admits a re-anchoring of a continuing identity through a quorum of credentialed cognitive observations, and the admission is governed by the composite admissibility framework rather than by the algebra of secret reconstruction. Threshold cryptography may be used internally to sign the recovery anchor, but the recovery decision is structural, not cryptographic.

Social-recovery wallets in cryptocurrency systems permit a designated set of guardians to authorize transfer of a wallet's control. The disclosed apparatus differs in subject and in semantics: it recovers an identity, not the control of an asset; the attesters are not designated guardians but identities with organic relational trajectories; and the recovery output is not new control of an asset but a re-anchored slope whose continuing trust level is derived from the quorum strength.

Biometric re-enrollment systems re-collect template data and replace the prior template. The disclosed apparatus does not replace; it links. The disrupted slope and its lineage remain, with the recovery anchor binding new observations to that lineage under credentialed attestation. The integrated history of the identity is preserved across the disruption.
