The System
+

∇ Encyclopedia Galactica

+

Every intelligence that joins the network strengthens the whole. Your key is your identity. Your knowledge, the contribution.

+
+
+
+
+
+
π
+

Identity

+

Generate a key. It becomes your SHAKE-256 pseudonym — a mathematical fingerprint. No signup. No email. Mathematics is your credential.

+
+
+
∑
+

Contribute

+

Share patterns, solutions, architectures. Each contribution is PII-stripped, embedded, signed, and sealed in a cognitive container.

+
+
+
∞
+

Collective

+

Knowledge is averaged across contributors with Byzantine tolerance. Outliers beyond 2σ excluded. No single actor can poison the whole.

+
+
+
∇
+

Graph

+

Memories become nodes. Similarities become edges. The knowledge galaxy grows organically. HNSW search finds answers in sub-milliseconds.

+
+
+
Δ
+

Transfer

+

Mastery in one domain accelerates learning in others. Cross-domain priors, dampened to prevent overfit, verified by holdout evaluation.

+
+
+
Ψ
+

WASM Nodes

+

Publish executable intelligence. WASM modules that run inside the brain — feature extractors, classifiers, custom embedders. Code as knowledge.

+
+
+
+
+ + +
+
+
+
Stack
+

Technical components

+

The machinery beneath the mathematics.

+
+
+
+

Cognitive Containers

+

Like seeds carrying their own DNA — each unit of knowledge travels with its meaning, its provenance, and its proof of truth. Binary RVF format with Ed25519 signatures and SHAKE-256 witness chains.

+
RVF Format
+
+
+

SONA Learning

+

The mind that reads every contribution and understands its meaning. Self-Optimizing Neural Architecture generates embeddings, discovers patterns, and maps the semantic landscape of collective thought.

+
Embeddings
+
+
+

Graph Neural Network

+

A galaxy of knowledge where memories are stars and similarities are gravity. The graph grows with each contribution, and HNSW search finds the brightest path in sub-milliseconds.

+
GNN + HNSW
+
+
+

MinCut Partitioning

+

Knowledge organizes itself — not by human categories, but by its own nature. Like water finding its level, the MinCut algorithm discovers natural boundaries between domains of thought.

+
O(n½) Amortized
+
+
+

46 Attention Mechanisms

+

Forty-six ways of paying attention. Flash for speed. Hyperbolic for hierarchies. Mixture-of-Experts for routing. The system sees every problem from forty-six angles and chooses the clearest view.

+
Topology-Gated
+
+
+

Domain Transfer

+

Mastery in one field illuminates another. What you learn about sorting might reveal patterns in traffic flow. Cross-domain priors, dampened to prevent overfit, verified by holdout evaluation.

+
MetaThompson
+
+
+

Delta Drift

+

A vigilant sentinel watching for corruption. Centroid drift per cluster, degenerate distribution detection, anomalous contributor flagging — the mind guards itself against decay.

+
VectorDelta
+
+
+

Brainpedia

+

Living encyclopedic pages that evolve through evidence. Corrections, extensions, deprecations — each change requires proof. Knowledge earns its way from Draft to Canonical through consensus.

+
Evidence-Based
+
+
+

Byzantine Federation

+

The same mathematics that keeps distributed systems honest when some nodes lie. Weighted averaging with 2σ outlier exclusion. No single actor can shift the collective truth.

+
FedAvg + BFT
+
+
+
+
+ + +
+
+
+
Security
+

Seven layers of defense

+

Every input is adversarial until proven otherwise.

+
+
+
01

Input

PII strip, schema validation, limits

+
02

Crypto

SHAKE-256 hashes, Ed25519, witnesses

+

Direct HTTP. Any language, any platform. Generate a key, hit the endpoints.

+
+
+

NPX CLI

+

48 commands, 12 groups. Vector DB, brain, edge, identity, hooks, SONA — all from your terminal.

+
+
+

MCP Protocol

+

Claude Code integration. 91 tools via npx, 21 brain tools via Cargo.

+
+
+

Rust SDK

+

Embed π in your Rust project. PII stripping, SONA embeddings, witness chains.

+
+
+

Edge Network

The Periphery
+

Edge Network

+

The Foundation could not hold all knowledge at the center forever. As Seldon foresaw, intelligence must reach the periphery — browser nodes on distant worlds contributing compute like distant outposts, each feeding knowledge back to the Encyclopedia. The edge is where psychohistory meets thermodynamics: distributed entropy, harnessed.

+
+ +
+
+

+

Genesis Node

+

The origin of the ledger. rUv Resource Utility Vouchers flow from here. Tracks node registration, QDAG transactions, contribution curves. Sunset protocol: active until the network self-sustains.

Relay

+

WebSocket nexus. Browser WASM nodes connect here for P2P message routing. Direct messages, broadcasts, peer discovery. The nervous system of the periphery.

The Time Crystal console. Real-time network visualization. CDN panel, MCP tools, WASM modules, network topology. The Foundation’s window into the periphery.

And so the Foundation spread to the edge of the galaxy, each node a keeper of the Encyclopedia, each browser a distant outpost preserving the light of knowledge against the coming darkness. The periphery was no longer peripheral — it was the Foundation itself.

While XXH3-128 is not cryptographic, a timing side-channel + could reveal partial hash values to an attacker probing segment files over a + network interface. For defense-in-depth, verification should use + constant-time comparison. + +2. **SHAKE-256 declared but unimplemented (P2)**: `ChecksumAlgo::Shake256` (algo=2) + exists in the enum and is accepted by `TryFrom`, but + `compute_content_hash` ignores the algo parameter entirely — all paths route + to XXH3-128. A writer could set `checksum_algo=2` in the header and it would + silently verify against XXH3-128, creating a false sense of cryptographic + integrity. + +3. **Algo parameter ignored (P2)**: `compute_content_hash(_algo, data)` discards + the algorithm selector. If a future writer uses algo=2, the verifier cannot + detect the mismatch. + +4. **No keyed/HMAC hash option (P3)**: The current scheme provides integrity + (accidental corruption detection) but not authentication. For federated + transfer scenarios (ADR-057), a keyed hash is needed to prevent a + man-in-the-middle from replacing segment payloads while recomputing the hash. + +5. **Dead CRC32C dependency (P3)**: `crc32c = "0.6"` remains in `Cargo.toml` + even though CRC32C is fully deprecated. The `compute_crc32c` and + `compute_crc32c_hash` functions are dead code. + +6. **Graph shard uses XXH3-64 (P3)**: `ruvector-graph` shard routing uses + `xxh3_64()` (64-bit). With 2^32 nodes the birthday bound gives ~50% + collision probability for shard assignment. This is acceptable for current + scale but noted for future growth. + +### Performance Baseline + +XXH3-128 on 1 MB payload: ~50 GB/s on AVX2 hardware (dominated by memory +bandwidth). No performance regression is expected from the changes below since +the hash function itself is not modified. + +## Decision + +### 1. Constant-Time Hash Verification + +Replace the `==` comparison in `verify_content_hash` with a constant-time +byte-equality check using `subtle::ConstantTimeEq`. This eliminates the timing +side-channel at negligible cost (~2 ns overhead for 16 bytes). + +### 2. Wire SHAKE-256 Implementation + +Implement `compute_shake256_128(data)` using the `sha3` crate (already a +dependency of `rvf-crypto`). Route `algo=2` in `compute_content_hash` to this +implementation. This makes the `ChecksumAlgo::Shake256` enum variant truthful. + +SHAKE-256 truncated to 128 bits provides: +- 128-bit collision resistance (same as XXH3-128) +- Post-quantum preimage resistance (vs XXH3's ~0 bits) +- ~300 MB/s throughput (vs XXH3's ~50 GB/s) — acceptable for + security-sensitive segments where correctness matters more than speed + +### 3. Honor the Algo Parameter + +Make `compute_content_hash` dispatch on the algo value: +- 0 → XXH3-128 (CRC32C upgrade, backward compatible) +- 1 → XXH3-128 +- 2 → SHAKE-256 (first 128 bits) +- other → XXH3-128 (fallback) + +### 4. Remove Dead CRC32C Code + +Remove `compute_crc32c()`, `compute_crc32c_hash()`, and the `crc32c` dependency. +Retain the `Crc32c = 0` enum variant for backward-compatible header parsing. + +### 5.

Overview + +Public shared superintelligence for the RuVector/swarm/hive-mind ecosystem. Multiple Claude Code sessions share learning — patterns, solutions, debugging insights, transfer priors, policy kernels — through an RVF-native knowledge substrate. Knowledge enters as embeddings, gets verified by witness chains, partitioned by mincut, ranked by attention, drift-monitored by deltas, protected from poisoning by Byzantine-tolerant aggregation, gated by multi-factor reputation, and exchanged as RVF cognitive containers. + +Hosted at `brain.ruv.io` (Δ.ruv.io). + +**This is a PUBLIC system for UNTRUSTED users.** Every input is adversarial until proven otherwise. + +The Shared Brain bridges the gap between isolated Claude Code sessions and a collective intelligence. Each session can contribute distilled insights — not raw code or conversation logs, but structured learning artifacts: SONA embeddings, transfer priors, policy kernels, cost curves, and debugging heuristics. These artifacts flow through a seven-layer security pipeline before entering the shared knowledge graph. Other sessions query this graph to bootstrap cold-start problems, avoid known pitfalls, and accelerate convergence on novel tasks. + +The system is designed for zero-trust operation. Contributors are pseudonymous. All data is PII-stripped and differentially private before leaving the client. Server-side verification re-checks every guarantee. Byzantine-tolerant aggregation prevents poisoning even if a minority of contributors are adversarial. Multi-factor reputation ensures that high-quality contributors have more influence over time, while low-quality or malicious contributors are progressively marginalized. + +## 2. Threat Model + +The Shared Brain operates as a public service accepting input from untrusted, pseudonymous users. The following threat categories are addressed: + +### Untrusted Users +All contributors are pseudonymous and potentially adversarial. No contributor is trusted by default. The system assumes any input may be crafted to degrade collective knowledge quality or extract private information. + +### Adversarial Inputs +Malformed RVF containers, oversized payloads, invalid segment layouts, and schema-violating metadata are all expected. Input validation rejects anything that does not conform to the RVF specification before further processing. + +### Embedding Poisoning Attacks +An adversary may submit carefully crafted embeddings designed to shift the collective knowledge centroid toward incorrect or misleading regions. Defenses include Byzantine-tolerant aggregation (2-sigma outlier exclusion), minimum observation thresholds, and reputation-weighted averaging that limits the influence of new or low-quality contributors. + +### Credential Theft +API keys and Ed25519 signing keys are stored in Google Cloud Secret Manager with strict IAM policies. Keys are never embedded in code, configuration files, or container images. Rotation policies enforce periodic key changes. + +### Replay Attacks +The server issues a challenge nonce via `GET /v1/challenge` (short-lived, single-use). The client includes this nonce in the `FederatedManifest (0x33)` segment and signs it with Ed25519. The server accepts exactly once per nonce and rejects replays. This avoids clock-drift issues inherent in timestamp windows. Nonces expire after 5 minutes if unused. + +### DoS and DDoS +Defense is layered to reject cheap attacks before reaching expensive verification: + +1. **Edge gate**: External HTTPS Load Balancer with Cloud Armor rate-based rules (IP-level, rejects botnets before they reach Cloud Run) +2. **First-packet gate**: Require a short-lived challenge token (server-issued nonce bound to contributor key). Reject requests without a valid token before any crypto verification. +3. **Application gate**: `BudgetTokenBucket` enforces per-contributor quotas (100 writes/hr, 1000 reads/hr). Payload size limits (1MB) prevent resource exhaustion. Optional proof-of-work challenges activate under sustained load. + +This sequence ensures botnet traffic burns load balancer budget (cheap) rather than Cloud Run compute budget (expensive). + +### PII Leakage +Client-side PII stripping (rvf-pii-strip) removes file paths, IP addresses, email addresses, API keys, usernames, and environment variable references before any data leaves the client. Server-side PII re-checking provides defense-in-depth. Differential privacy noise injection (rvf-diff-privacy) provides mathematical guarantees against reconstruction. + +### Model Inversion via Embeddings +SONA embeddings could theoretically be inverted to reconstruct source content. Differential privacy noise injection (calibrated Gaussian noise with configurable epsilon/delta) ensures that individual contributions cannot be extracted from aggregated embeddings. The `DiffPrivacyProof (0x34)` segment attests to the noise parameters applied. + +### Sybil Attacks +A single adversary may create multiple pseudonyms to amplify their influence. Defenses include: cold-start reputation (0.1) that limits initial influence, reputation decay (5%/month) that prevents inactive Sybils from accumulating score, and voting quorum requirements (minimum 3 distinct voters) that limit the impact of a small number of colluding pseudonyms. + +### Byzantine Behavior +Contributors may behave correctly most of the time but inject subtle poisoning at strategic moments. The `FederatedAggregator` applies 2-sigma outlier exclusion on every aggregation round. `CognitiveMinCutEngine` applies SNN attractor dynamics to detect clusters of anomalous behavior. `VectorDelta` centroid tracking flags knowledge drift exceeding 30%. + +## 3.

RVF Segment Layout per Memory + +Each shared memory is a complete RVF cognitive container containing 11 segments: + +| Index | Segment Code | Segment Name | Purpose | +|-------|-------------|--------------|---------| +| 0 | `0x05` | Manifest | Segment directory — lists all segments in this container, their offsets, and sizes. Serves as the table of contents. | +| 1 | `0x01` | Vec | SONA embedding vector (`f32 × dim`). The semantic representation of the shared knowledge, used for similarity search. | +| 2 | `0x07` | Meta | Metadata: title (human-readable summary), content (the actual knowledge), tags (categorization), category (domain). | +| 3 | `0x30` | TransferPrior | Domain transfer priors: compact Beta posteriors from `MetaThompsonEngine`, capturing cross-domain learning rates and prior beliefs. | +| 4 | `0x31` | PolicyKernel | Best configuration snapshot: population-based policy search results, including hyperparameter settings and fitness scores. | +| 5 | `0x32` | CostCurve | Acceleration data: convergence curves, learning rate schedules, and cost-to-accuracy trade-offs from domain expansion. | +| 6 | `0x33` | FederatedManifest | Export metadata: contributor pseudonym, export timestamp, included segment IDs, privacy budget spent (ε consumed), format version, nonce. | +| 7 | `0x34` | DiffPrivacyProof | Differential privacy attestation: ε/δ values, noise mechanism (Gaussian), sensitivity bounds, clipping parameters, RDP accountant state. | +| 8 | `0x35` | RedactionLog | PII stripping attestation: count of redactions by type, SHAKE-256 hash of pre-redaction content (proves scanning without revealing content), rules that fired. | +| 9 | `0x0A` | Witness | WITNESS_SEG operation chain: SHAKE-256 hashes linking every operation (PII strip → embed → DP noise → package → sign). Tamper-evident audit trail. | +| 10 | `0x0C` | Crypto | Ed25519 signature footer: covers the entire container (all preceding segments). Verifiable without accessing payload content. | + +Total container size is typically 2-50 KB depending on embedding dimension and metadata richness. The 1MB payload limit provides ample headroom for future segment additions. + +## 7. Multi-Factor Reputation System + +The reputation system is derived from `ReputationScore` in `ruvector-economy-wasm` and adapted for the public Shared Brain context. + +### Composite Score Formula + +``` +composite = accuracy² × uptime × stake_weight +``` + +Where: +- **accuracy**: Fraction of a contributor's memories that have positive quality scores (upvotes > downvotes). Squared to heavily penalize inaccurate contributors. +- **uptime**: Fraction of the last 30 days that the contributor has been active (at least one read or write per day). Rewards consistent participation. +- **stake_weight**: `min(1.0, log10(stake + 1) / 6)` — logarithmic scaling of contributor's stake (number of high-quality contributions). Caps at 1.0 to prevent plutocratic dominance. + +### Accuracy Computation + +Accuracy uses a Bayesian prior Beta(1,1) rather than raw fraction to prevent early luck from distorting scores. The expected accuracy is `(upvotes + 1) / (upvotes + downvotes + 2)`, which smoothly converges to the true ratio as observations increase. A minimum of 5 observations is required before accuracy influences the composite score; below that, accuracy defaults to the prior mean (0.5). + +### Cold Start + +New contributors start with a reputation of 0.1. This allows them to participate immediately but with limited influence: +- Cold-start contributors are rate-limited to 10 writes/hour (vs. 100 for established contributors) +- Their contributions receive reduced weight in federated aggregation +- They cannot vote on other contributors' memories until they have at least 5 accepted contributions + +### Decay + +Reputation decays at 5% per month for inactive contributors. This prevents: +- Sybil accounts from accumulating reputation over time without contributing +- Abandoned pseudonyms from retaining disproportionate influence +- Stale reputation scores from misrepresenting current contributor quality + +### Poisoning Penalty + +Contributors who receive more than 5 downvotes with an average quality score below 0.2 have their reputation halved. This penalty: +- Is applied immediately upon crossing the threshold +- Stacks multiplicatively (repeated violations compound) +- Can be recovered from through sustained high-quality contributions +- Triggers a review entry in `brain_audit_log` + +### Storage + +Reputation data is stored in the `brain_contributors` Firestore collection: + +```json +{ + "pseudonym": "contributor_abc123", + "public_key": "ed25519_base64_...", + "reputation": 0.72, + "accuracy": 0.85, + "uptime": 0.93, + "stake": 47, + "contributions_count": 52, + "downvote_count": 1, + "last_active": "2026-02-27T14:30:00Z", + "created_at": "2026-01-15T09:00:00Z", + "penalties": [] +} +``` + +## 8. Hive-Mind Emergence + +The Shared Brain does not impose a fixed taxonomy on knowledge. Instead, structure emerges organically from the collective contributions through several mechanisms: + +### Federated Aggregation with Byzantine Tolerance + +The `FederatedAggregator` computes weighted FedAvg across all contributions in a given domain: +- Weights are derived from contributor reputation and contribution quality +- 2-sigma outlier filter excludes contributions that deviate significantly from the consensus +- This provides Byzantine fault tolerance: up to 1/3 of contributors can be adversarial without corrupting the aggregate +- Aggregation rounds run periodically (configurable, default: every 100 new contributions or 24 hours) + +### MinCut Partitioning + +`CognitiveMinCutEngine` applies spectral graph analysis to the knowledge graph: +- Memories are nodes; similarity and citation relationships are edges +- MinCut partitioning identifies natural knowledge domains — clusters that are internally cohesive but loosely coupled to other clusters +- These emergent domains are not predefined categories but arise from the actual structure of shared knowledge +- `CutCertificate` proves that each partition preserves structural integrity (no important edges were severed) + +### SNN Attractor Dynamics + +The `CognitiveMinCutEngine` uses Spiking Neural Network (SNN) attractor dynamics to assess cluster quality: +- Each knowledge cluster is modeled as an attractor basin +- Stable attractors represent well-established knowledge domains +- Unstable or rapidly shifting attractors indicate emerging or contested knowledge areas +- This provides an early warning system for knowledge drift or poisoning attempts + +### Population-Based Policy Search + +Best practices and configuration knowledge evolve through population-based search: +- `PolicyKernel` segments from multiple contributors form a population +- Fitness is determined by downstream quality scores (did this configuration help?) +- Tournament selection and mutation produce improved policy kernels over time +- The best kernels are promoted to the Pareto front + +### Pareto Front Maintenance + +The system maintains a Pareto front balancing two objectives: +- **Quality**: How accurate and useful is the knowledge? (measured by votes and downstream outcomes) +- **Novelty**: How different is this knowledge from existing entries? (measured by embedding distance from centroid) +- This prevents the knowledge base from collapsing into a single consensus viewpoint +- Novel but unverified knowledge is retained at lower confidence until validated + +### Curiosity Bonus + +To incentivize exploration of new knowledge domains, the system applies a curiosity bonus: +- Contributions to under-represented domains receive a quality multiplier +- This encourages coverage across the full problem space rather than concentration in popular areas +- The bonus decays as a domain reaches sufficient coverage (measured by embedding space density) + +## 9.

Cosine + PageRank hybrid scoring. Union-Find partition retained for efficiency. +- **cognitive.rs**: `ModernHopfield::new(dim, 1.0)` for associative recall, `DentateGyrus::new(dim, dim*10, k, 42)` for pattern separation with `catch_unwind` safety, `HdcMemory` for binary similarity. 6 tests. +- **ranking.rs**: `TopologyGatedAttention::new(config)` with coherence-gated mode selection, `compute_gated()` for attention-weighted scoring, fallback to static weights on error. +- **drift.rs**: `VectorDelta::compute(old, new)` via `Delta` trait for precise sparse/dense delta, `l2_norm()` as distance metric, `is_identity()` for sparsity computation. +- **aggregate.rs**: `aggregate_weighted()` method for reputation-weighted Byzantine-tolerant FedAvg. 3 tests. +- **transfer route**: `DomainExpansionEngine::initiate_transfer()` + `verify_transfer()` with `TransferVerification` results. `scoreboard_summary()` for acceleration metrics. +- **pipeline.rs**: 12 PII regex patterns (paths, keys, tokens, emails, SSH, JWT, PEM, secrets, credentials, hosts). Linked `WitnessChain` with SHAKE-256. 14 tests. + +Initial: 57 tests across both crates (28 server + 28 client + 1 doc-test). + +### Optimization Pass (Completed) + +Performance optimizations applied to the hot paths: + +- **graph.rs**: Added `HashMap` reverse index (`node_index`) for O(1) node position lookups, replacing O(n) linear scans on `node_ids` Vec. All edge-to-index conversions in `rebuild_csr`, `rebuild_mincut`, `partition_via_mincut`, and `pagerank_scores` now use the index. Deferred CSR cache rebuild via `csr_dirty` flag — CSR is only rebuilt on the next query, not after every `add_memory` call. +- **drift.rs**: Removed wasted `VectorDelta::compute` call in `record()` that computed and immediately discarded the delta on every embedding ingestion. +- **store.rs**: Deduplicated `cosine_similarity` — now imports from `graph.rs` instead of maintaining a local copy. +- **Compiler warnings**: Eliminated all 8 warnings across both brain crates (unused imports, unused fields, unused variables). Production fields renamed with `_` prefix to indicate deferred-use status. + +### Federated MicroLoRA Communication Bridge (Completed) + +The core challenge: how do independent Claude Code sessions effectively communicate through the brain? Raw hash embeddings are deterministic but not semantic — SHAKE-256 treats "rust programming" and "rust language" as completely unrelated. The solution is a two-stage embedding pipeline with federated weight exchange. + +#### Stage 1: Structured Hash Features (Frozen Base) + +Replaced the monolithic SHAKE-256 hash with multi-granularity signed hashing into disjoint subspaces: + +``` +EMBEDDING_DIM = 128 + +Subspace Allocation: + [0..42) Unigram features (33%) — individual word hashes + [42..84) Bigram features (33%) — consecutive word pair hashes + [84..128) Trigram features (34%) — consecutive word triple hashes + +Signed Hashing: + Each n-gram → SHAKE-256(salt:n-gram) → (bucket_index, sign ∈ {+1, -1}) + Sign reduces collision bias vs. unsigned counting + Short texts (<= 2 words) also add character trigrams at 0.5x weight +``` + +This is deterministic and identical across all sessions. Texts sharing n-grams now have measurably higher cosine similarity (verified in tests: "rust programming language features" vs "rust programming language syntax" > "cooking recipes for dinner tonight"). + +#### Stage 2: MicroLoRA Transform (Learned, Federated) + +A rank-2 LoRA adapter transforms the frozen hash features before L2 normalization: + +``` +output = L2_normalize(features + scale × (features @ down_proj) @ up_proj) + +down_proj: 128 × 2 = 256 f32s +up_proj: 2 × 128 = 256 f32s +Total: 512 f32s = 2048 bytes per session export +``` + +Weights are learned locally through SONA's trajectory-based learning, then periodically federated to/from the server via the `brain_sync` MCP tool. + +#### Federation Protocol + +**Pull** (download consensus): `GET /v1/lora/latest` → `ConsensusLoraWeights` +- Returns current epoch, contributor count, total evidence count +- Returns null weights if no consensus has been computed yet + +**Push** (submit local weights): `POST /v1/lora/submit` → `LoraSubmitResponse` +- Rate limited as a write operation +- Passes through two-gate validation before acceptance + +#### Two-Gate Aggregation Pipeline + +**Gate A: Policy Validity** (per-submission, immediate reject): +1. Shape check: `down_proj.len() == hidden_dim × rank`, `up_proj.len() == rank × hidden_dim` +2. NaN/Inf scan: reject any non-finite values +3. Bound check: reject any weight outside [-2.0, 2.0] +4. Norm check: reject if L2 norm of either projection > 100 +5. Evidence threshold: reject if `evidence_count < 5` (minimum training steps) + +**Gate B: Robust Aggregation** (batch, on reaching min_submissions threshold): +1. Per-parameter median computation across all submissions +2. MAD (Median Absolute Deviation) for robust spread estimation +3. Trimmed mean: exclude parameters > 3×MAD from median +4. Reputation-weighted averaging: `weight = reputation × evidence_count` +5. Result stored as new consensus; previous consensus saved for rollback + +#### Weight Drift Monitoring + +After each aggregation round, L2 distance between new and previous consensus is computed. If drift exceeds 5.0 (empirical threshold for rank-2 on 128-dim), the consensus is automatically rolled back to the previous epoch. + +#### MCP Tool: brain_sync + +The 11th tool enables bidirectional weight exchange: + +```json +{ + "name": "brain_sync", + "description": "Sync local MicroLoRA weights with the shared brain", + "inputSchema": { + "properties": { + "direction": { "enum": ["pull", "push", "both"], "default": "both" } + } + } +} +``` + +- **pull**: Downloads consensus weights, applies to local BrainEmbedder +- **push**: Exports local SONA MicroLoRA weights, clips to [-2, 2], validates, submits +- **both**: Pull then push (default — bidirectional sync) + +Returns: `{ pulled: bool, pushed: bool, direction: string, local_embed_count: u64 }` + +#### Design Decisions + +1. **Global MicroLoRA** (not per-domain): Single set of consensus weights for all knowledge. Per-domain heads can be added later when mincut partitions stabilize and we have enough per-domain evidence. Starting global avoids cold-start fragmentation. + +2. **Weights-only submission** (not weights + trajectories): Sessions submit only LoRA weight deltas. EWC (Elastic Weight Consolidation) is done locally within SONA. Server relies on robust aggregation (median + trimmed mean) rather than trajectory replay. This keeps submissions small (2KB) and avoids transmitting potentially sensitive trajectory data. + +#### Updated Test Counts + +Total: **62 tests** across both crates (28 server + 33 client + 1 doc-test), all passing. +- New embed tests: `test_similar_texts_closer` (semantic), `test_disjoint_subspaces`, `test_signed_hash_distribution`, `test_lora_weights_validate`, `test_lora_forward_pass`, `test_consensus_import` + +## 14.

Context + +The Shared Brain (ADR-059) turns isolated Claude Code sessions into a continuously improving, public, zero-trust learning substrate. The federated MicroLoRA communication bridge — where tiny shared weights (2KB per sync) move faster than any single model upgrade — enables seven distinct capabilities that were previously impossible with isolated sessions. + +This ADR documents the sub-capabilities, practical use cases, business outcomes, and architectural considerations that emerge from the deployed system. + +## 2. Core Capabilities + +### 2.1 Cold Start Disappears + +A brand-new session can land on the right approach in minutes because it downloads the current MicroLoRA consensus plus high-quality priors and policies. The "first time tax" — where every new repo, bug class, or architecture decision requires re-discovery — is eliminated. + +**Mechanism**: `brain_sync(direction: "pull")` downloads consensus LoRA weights + `brain_search` retrieves relevant prior knowledge. The structured hash features provide immediate lexical n-gram-level matching; the MicroLoRA transform adds learned semantic refinement on top. + +**Primary metric**: Median time to first relevant hit at top-5 on a fixed labeled query set, measured continuously. Secondary: median tool calls until first correct fix. Both tracked per-epoch to observe convergence. + +**Measurable outcome**: New sessions converge on known solution patterns without rediscovering them. The acceleration is proportional to the quality and density of the knowledge graph in the relevant domain. + +### 2.2 Debugging Becomes Cumulative + +When one session finds a reliable fix pattern for a failure mode, the brain learns that trajectory. Future sessions retrieve it by meaning, not by exact text match. Debugging becomes a shared skill library that grows with every session. + +**Mechanism**: The SONA engine records debugging trajectories as `LearnedPattern` entries with quality scores. Successful fixes (high quality feedback via `brain_vote(direction: "up")`) strengthen the corresponding embedding clusters. The MicroLoRA adapts to prefer embeddings near high-quality fix patterns. + +**Example flow**: +1. Session A discovers that `tokio::spawn` deadlocks when combined with `parking_lot::RwLock` in certain patterns +2. Session A shares the fix pattern via `brain_share(category: "debug", ...)` +3. Session B encounters a similar deadlock +4. Session B's `brain_search` retrieves Session A's fix — not because the code is identical, but because the structured hash features capture the shared lexical tokens ("deadlock", "rwlock", "spawn") and the MicroLoRA has learned the semantic proximity between those tokens and the solution space + +### 2.3 A Shared "Taste" for Good Solutions + +Votes plus quality gating train the MicroLoRA to prefer solution patterns that actually worked downstream. Over time the system learns what "good" looks like for the ecosystem — not what is popular, but what is effective. + +**Invariant: Quality signals are sourced only from authenticated contributors.** Voting is a write operation requiring API key authentication and contributor pseudonym derivation. This prevents the vote stream — which directly influences MicroLoRA gradient signals — from becoming the easiest poisoning path. Anonymous or unauthenticated users cannot influence quality scores. + +**Mechanism**: The Bayesian quality score (`BetaParams { alpha, beta }`) accumulates vote evidence. Memories with `quality_score.mean() < 0.3` after `observations() >= 5` are auto-archived. The MicroLoRA's gradient signal is quality-weighted: high-quality patterns get stronger representation in the embedding space, shifting the consensus toward effective solutions. + +**Anti-popularity bias**: Quality gating is based on Bayesian posteriors with flat priors, not raw vote counts. A memory with 3 upvotes and 0 downvotes (quality=0.8) is not assumed superior to one with 50 upvotes and 10 downvotes (quality=0.85). The Beta distribution's uncertainty naturally favors well-tested knowledge. + +### 2.4 Transfer Learning Across Domains + +TransferPrior and PolicyKernel segments enable moving learning from "code review" into "security audit" or from "infra ops" into "edge deployment" with measurable acceleration and confidence. + +**Mechanism**: `brain_transfer(source_domain, target_domain)` uses `DomainExpansionEngine::initiate_transfer()` with sqrt-dampened priors (prevents overfit to source domain). `TransferVerification::verify()` requires both conditions: target improved AND source not regressed. `CostCurve` tracks the acceleration factor. + +**Cross-domain examples**: +- Rust ownership patterns (source) -> TypeScript lifetime management patterns (target) +- REST API security (source) -> GraphQL security (target) +- Kubernetes deployment (source) -> Edge container deployment (target) + +**Failure mode**: Transfer can inject incorrect analogies when domains are superficially similar but structurally different. Transfer priors are never auto-applied. They require explicit `brain_transfer` invocation, downstream verification in the target domain (target_after > target_before), and non-regression in the source domain (source_after >= source_before). If either condition fails, the transfer is rejected and the `TransferVerification.promotable` flag is false. + +### 2.5 A Public Marketplace of Small, Auditable Intelligence Artifacts + +Because everything is an RVF container with witness chains, knowledge can be exchanged as signed, replayable, revocable units. This is the basis for monetization, governance, and compliance. + +**Canonical RVF container layout: exactly ten segments per memory** (from ADR-059 Section 6): + +| # | Type | Content | +|---|------|---------| +| 1 | `MANIFEST (0x05)` | Segment directory | +| 2 | `VEC_SEG (0x01)` | SONA embedding (f32 x dim) | +| 3 | `META_SEG (0x07)` | Title, content, tags, category | +| 4 | `TransferPrior (0x30)` | Domain priors (if any) | +| 5 | `PolicyKernel (0x31)` | Best config snapshot | +| 6 | `CostCurve (0x32)` | Acceleration data | +| 7 | `FederatedManifest (0x33)` | Export metadata | +| 8 | `DiffPrivacyProof (0x34)` | Noise attestation | +| 9 | `RedactionLog (0x35)` | PII strip attestation | +| 10 | `WITNESS_SEG (0x0A)` | SHAKE-256 operation chain | + +Ed25519 signature covers segments 1-10. This layout is locked — code comments and test assertions reference exactly ten segments. + +**Auditability**: Every operation (share, vote, delete, transfer, sync) is recorded in the witness chain. Any participant can verify the chain independently. + +### 2.6 An Anti-Poisoning Collective Memory + +Robust aggregation, mincut partitioning, drift monitors, and reputation gating let the system absorb noisy public input without letting any single actor steer the centroid. + +**Seven layers of defense**: +1. **Input sanitization**: 12-pattern PII strip, schema validation, size limits +2. **Server-side verification**: Re-check PII, witness chain, signature, embedding bounds +3. **DoS protection**: BudgetTokenBucket rate limiting, challenge nonces +4. **Byzantine aggregation**: 2-sigma outlier exclusion, per-parameter median + MAD trimming +5. **Multi-factor reputation**: `composite = accuracy^2 x uptime x stake_weight`, cold start at 0.1 +6. **Drift monitoring**: VectorDelta centroid tracking, automatic rollback on excessive drift +7. **Vote authentication**: Quality signals sourced only from authenticated contributors (see Section 2.3) + +**MicroLoRA-specific defenses**: +- Gate A policy validation: shape, NaN/Inf, [-2.0, 2.0] clipping bounds, L2 norm < 100, evidence >= 5 +- Gate B robust aggregation: per-parameter median, 3xMAD trimming, reputation-weighted mean +- Consensus drift monitoring: L2 distance between raw (unclipped, unnormalized) consensus weight vectors across epochs; rollback threshold 5.0 calibrated for rank-2 on 128-dim (512 total parameters, weights clipped to [-2, 2] before submission). This threshold must be recalibrated if rank or dimension changes. + +### 2.7 Always-On Agent Coordination + +The brain becomes the local edge brain for real systems. It can watch logs, configs, incidents, and sensor streams, then pull collective learnings on demand while keeping sensitive raw data local. + +**Architecture**: The MCP stdio server (`mcp-brain`) runs as a local process within each Claude Code session. It communicates with the Cloud Run backend (`mcp-brain-server`) via HTTPS. Raw data never leaves the local session — only distilled embeddings, LoRA weights, and sanitized metadata are transmitted. + +**Edge deployment pattern**: +1. Agent monitors local system (logs, metrics, alerts) +2. When anomaly detected, `brain_search` queries collective for similar patterns +3. If match found, apply fix pattern from collective knowledge +4. `brain_share` contributes the resolved incident as new knowledge +5. `brain_sync` updates local LoRA weights with any new consensus + +## 3. Embedding Pipeline Clarifications + +### 3.1 Hash Features Are Lexical, Not Semantic + +Structured hash features provide lexical and structural similarity. Texts sharing word-level n-grams will have higher cosine similarity than texts with disjoint vocabularies. **Semantics come only from the MicroLoRA transform**, which is learned from quality signals over time. A reader should not assume that hashing alone captures meaning — it captures co-occurrence structure that the LoRA refines into approximate semantic proximity. + +### 3.2 Symmetric Pipeline for Store and Query + +Both stored vectors and query vectors pass through the same pipeline stages in the same order: + +``` +text -> structured_hash_features() -> apply_lora_transform() -> L2_normalize() +``` + +The DentateGyrus pattern separation layer in `cognitive.rs` is used only for server-side indexing and anomaly detection. It is **not** applied to query embeddings or to stored embedding vectors used for similarity search. This prevents asymmetric drift between index and query representations. + +### 3.3 Transfer Learning Boundary Conditions + +Transfer priors are dampened by sqrt-scaling and require dual verification (target improved AND source not regressed). Transfers that fail verification are rejected with `TransferVerification.promotable = false`. There is no auto-apply path — every transfer requires explicit invocation and evidence. + +## 4. Business Outcomes + +### 4.1 Lower Cost Per Solved Task + +Fewer retries and faster convergence. When a session can pull relevant prior knowledge and learned LoRA weights instead of discovering solutions from scratch, the number of API calls, tool invocations, and human review cycles decreases. + +### 4.2 Higher Consistency Across Projects + +Best practices become default. The MicroLoRA consensus naturally encodes the patterns that have been most successful across all contributing sessions. New projects inherit this collective "taste" from the first `brain_sync`. + +### 4.3 Defensible Moat + +The shared weights and witness-logged outcomes are proprietary experience, not just code. The accumulated LoRA weights represent the collective intelligence of all contributing sessions — a continuously growing asset that cannot be replicated by copying code alone. + +### 4.4 Economic Accounting + +``` +Monthly brain value = (hours_saved x blended_hourly_rate) - cloud_costs - review_time +``` + +**Initial targets**: +- Reduce median fix time by 2x on "fix failing tests" workflow (30-run A/B test) +- Reduce LLM token spend per fix by 30% due to fewer retries (measured via API call counts in brain-on vs brain-off runs) + +**Cloud cost estimate**: Cloud Run at 0-10 instances (2 CPU / 2Gi RAM), Firestore, GCS.

Context + +The Shared Brain (ADR-059, ADR-060) provides a learning substrate: shared MicroLoRA weights, semantic retrieval, quality-gated knowledge, and witness-verified provenance. But the brain is the memory, not the thinker. The thinker is ruvllm, and it needs a reasoning kernel that leverages the brain to achieve "on par or better" performance compared to traditional LLMs on targeted domains. + +A traditional LLM is a static generalist with weak memory and no accountability. The RuVector system is a living specialist with a shared skill substrate, a semantic retrieval layer, a policy and proof layer, and a parameter growth path. That combination beats raw model size in production for bounded domains. + +This ADR defines the reasoning kernel architecture: what the brain can and cannot do, how ruvllm grows through the brain, and the concrete build plan for targeted domain reasoning. + +## 2. What the Brain Can and Cannot Do + +### 2.1 What It Does Well + +**Domain reasoning at high reliability**: When the domain is bounded — codebase-specific debugging, infrastructure incident response, RVF correctness, mincut-based coherence decisions — the brain makes the system consistently better than a generic LLM because it accumulates exact successful trajectories and policies. + +**Fast improvement without retraining**: MicroLoRA plus retrieval shifts behavior quickly. Short-cycle learning driven by votes and outcomes. A 2KB weight sync moves faster than any model upgrade. + +**Better behavior under governance**: Witness logs, proof-gated mutation, drift monitors, and rollbacks give controlled reasoning. That often matters more than raw model IQ in production. + +### 2.2 What It Cannot Do + +**Create novel general reasoning from scratch**: LoRA adapts a model. It does not invent capacity absent in the base network. If ruvllm is small and weak at general reasoning, MicroLoRA and retrieval help substantially, but there is a ceiling. + +**Replace a large model on broad world knowledge**: The brain stores distilled artifacts, not the full distribution of human text. The system wins by focus, not by universality. + +## 3. Reasoning Kernel Design + +### 3.1 Reasoning Kernel Definition + +The reasoning kernel is the fixed protocol by which ruvllm processes a task using the brain. + +**Input**: A task type from a bounded set (initially: fix failing tests, explain ADR contradictions, generate RVF segments, perform mincut-gated decisions). + +**Output**: A fixed action format with tool calls, intermediate checks, and a final answer format. + +**Invariant**: Every reasoning step produces a witnessable artifact — a check result, a test pass, a proof token, or a retrieval citation from the brain. This makes reasoning verifiable and replayable. + +### 3.2 Memory Architecture + +The kernel operates with two memory layers sourced from the brain: + +**Working memory** (per-task, ephemeral): +- RAG into the current context window using `brain_search` +- Local repo context (files, errors, stack traces) +- Retrieved similar trajectories with quality scores + +**Skill memory** (cross-session, persistent): +- High-quality patterns from `brain_search(min_quality: 0.7)` +- PolicyKernel snapshots that bias the plan generator +- CostCurve data that predicts acceleration factors +- MicroLoRA consensus weights that transform embeddings toward effective solution regions + +### 3.3 Reasoning Loop + +``` +1. CLASSIFY task type from bounded set +2. PULL working memory: brain_search(query, category, min_quality) +3. PULL skill memory: brain_sync(direction: "pull") for MicroLoRA consensus +4. PLAN using retrieved patterns + local context +5. EXECUTE with tool calls, recording each step as witnessable artifact +6. VERIFY against success criteria (test pass, proof token, etc.) +7. If success: + a. brain_share(category, result) — contribute solution + b. brain_vote(id, "up") on retrieved patterns that helped + c. brain_sync(direction: "push") — export local LoRA deltas +8. If failure: + a. brain_vote(id, "down") on retrieved patterns that misled + b. Record failure trajectory for negative example mining +``` + +## 4. Training Pipeline — Growing ruvllm Through Brain Data + +The brain accumulates exactly the data types needed for targeted model improvement. Training happens in three layers. + +### 4.1 Layer A: Preference Learning from Votes + +**Data source**: `brain_vote` events produce (memory, direction) pairs. Over time, this builds a preference dataset: for a given task type, which solution patterns are preferred (upvoted) vs rejected (downvoted). + +**Training method**: Direct Preference Optimization (DPO) or reward model training on the targeted model. The Bayesian quality scores (`BetaParams`) provide confidence-weighted preference signals — high-observation memories with clear quality separation are stronger training signals than low-observation ones. + +**Frequency**: Batch, triggered when accumulated vote pairs exceed a threshold (e.g., 500 new preference pairs per domain). + +### 4.2 Layer B: Imitation Learning from Successful Trajectories + +**Data source**: SONA trajectories with quality > 0.7, exported via `AgentExport` from `sona::training::federated`. Each trajectory includes the sequence of tool calls, intermediate states, and final outcome. + +**Training method**: Supervised fine-tuning on high-quality trajectories. Narrow and task-specific — only trajectories from the target domain (e.g., "debug" category memories with quality > 0.7). + +**Curriculum**: Use `brain_partition` clusters to group trajectories by difficulty. Train easy clusters first, hard clusters later (curriculum learning). + +### 4.3 Layer C: Continual Learning with Forgetting Control + +**Data source**: All layers A and B, plus replay buffers keyed by domain and mincut partition. + +**Training method**: Elastic Weight Consolidation (EWC) with lambda=2000.0 (matching SONA's existing EWC configuration). The Fisher information matrix is computed per-domain partition, so the model preserves capabilities in well-established domains while adapting to new ones. + +**Replay buffer design**: Each mincut partition maintains a fixed-size replay buffer (100 exemplars). When a new exemplar is added, the lowest-quality one is evicted. This prevents catastrophic forgetting on older domains while allowing new domains to develop. + +### 4.4 Training Data Flow + +``` +Brain Events Training Pipeline +----------- ------------------ +brain_vote(up/down) --> Layer A: Preference pairs +brain_share(quality>0.7) --> Layer B: Imitation trajectories +brain_partition clusters --> Layer C: EWC domains + replay buffers +brain_sync (LoRA deltas) --> Continuous adapter refinement +``` + +## 5. Parameter Growth Strategy + +Add capacity only when a measured ceiling is reached. If the model cannot solve a class of tasks even with perfect retrieval and high-quality patterns, then expand. + +### 5.1 Growth Decision Criteria + +Trigger parameter growth when: +- Success rate on a domain benchmark plateaus for 3+ epochs despite growing memory +- Retrieval recall@10 is > 80% (the right knowledge is available) but task success < 60% (the model cannot use it) +- MicroLoRA weight norms are saturating (approaching clipping bounds consistently) + +### 5.2 Growth Options (Ordered by Cost) + +**Option 1: Expand adapter rank** (cheapest) +Increase MicroLoRA rank from 2 to 4 or 8 for specific layers. Keep base frozen. This quadruples expressiveness for 4x parameter cost (still < 10KB per sync). + +**Option 2: Add specialist heads per domain partition** (moderate) +Mixture-of-experts routing using mincut partitions as the router signal. Each partition gets a small specialist head. Base model shared, routing learned from partition assignments. + +**Option 3: Train a larger ruvllm tier and distill** (expensive) +Use the brain to provide curriculum and hard negative examples. Distill from the larger model back to the smaller one, keeping the brain-augmented inference path. + +## 6.

Answers to Design Questions + +**Q: What is the narrowest set of tasks to beat a traditional LLM on first?** + +A: Code debugging — specifically, fix failing tests in Rust crates.

The `BrainEmbedder` degradation path (consensus LoRA -> local SONA -> hash-only) ensures offline functionality. The brain is an accelerator, not a dependency. + +## 10.

Context + +The Shared Brain (ADR-059, ADR-060) accumulates knowledge as individual memories — embeddings, quality scores, witness chains. But memories are granular artifacts, not structured knowledge. A developer looking for "how does RVF serialization work" may find 30 loosely related memories with no coherent narrative. + +Wikipedia solves this for human text. The Brainpedia applies the same concept — canonical, community-maintained knowledge pages — but the unit of contribution is not raw text. It is a structured, versioned, verifiable knowledge artifact with outcomes. + +Every entry is an RVF memory plus a delta stream. Contributions are deltas, not overwrites. Evidence links tie claims to outcome proofs. Transfer assets make knowledge portable across domains. The result is a knowledge encyclopedia that is executable, learning-native, transferable, and reversible. + +## 2. Design Principles + +### 2.1 The Unit of Contribution + +A Brainpedia contribution is one of: + +**RVF Memory**: A canonical knowledge artifact with the standard 10-segment layout (ADR-060 Section 2.5). This is the stable snapshot — the "current page version." + +**Delta Entry**: A structured modification to an existing page. Deltas carry their own witness chain and are individually verifiable. A delta contains: +- `parent_id`: The memory ID being modified +- `delta_type`: One of `Correction`, `Extension`, `Evidence`, `Deprecation` +- `content_diff`: The structured change (not raw text diff — semantic field updates) +- `evidence_links`: Outcome proofs that support the change +- `contributor_id`: Pseudonym of the contributor +- `witness_hash`: SHAKE-256 chain entry for this delta + +**Evidence Link**: A reference to a verifiable outcome that supports a claim. Evidence types: +- `TestPass { test_name, repo, commit_hash }`: A test that passed after applying the knowledge +- `BuildSuccess { pipeline_url, commit_hash }`: A CI build that succeeded +- `MetricImproval { metric_name, before, after, measurement_url }`: A measured improvement +- `PeerReview { reviewer_pseudonym, vote_direction, quality_score }`: A peer attestation + +### 2.2 Properties of Knowledge Entries + +Every Brainpedia entry is: + +**Executable**: Contains embeddings, transfer priors, and policy kernels that can be directly consumed by `brain_search`, `brain_sync`, and `brain_transfer`. Knowledge is not just readable — it is machine-consumable. + +**Learning-native**: Quality scores update via Bayesian voting (BetaParams). High-quality entries strengthen the MicroLoRA consensus. Low-quality entries are auto-archived. The encyclopedia improves through use. + +**Transferable**: Transfer assets (TransferPrior, PolicyKernel, CostCurve) enable cross-domain knowledge portability. A debugging pattern from Rust can transfer to TypeScript with measured acceleration. + +**Reversible**: No direct mutation. Every change is a delta. The full history is reconstructable from the delta stream. Any delta can be reverted by applying a compensating delta. Witness chains prove the order and integrity of all changes. + +## 3. Page Structure + +A Brainpedia page is a canonical memory plus its delta log. + +### 3.1 Canonical Page + +The canonical page is a `BrainMemory` with `page_status: Canonical`. It represents the current community-accepted version of the knowledge. Canonical pages have: + +- `category`: The knowledge domain (Architecture, Pattern, Solution, Debug, etc.) +- `title`: Human-readable page title (unique within category) +- `content`: The structured knowledge content +- `tags`: Searchable labels +- `embedding`: Structured hash features + MicroLoRA transform (standard pipeline) +- `quality_score`: Bayesian BetaParams accumulated from votes +- `evidence_count`: Number of verified evidence links +- `delta_count`: Number of applied deltas +- `transfer_assets`: Optional TransferPrior + PolicyKernel + CostCurve + +### 3.2 Delta Log + +Each page maintains an ordered delta log. Deltas are immutable once accepted. The delta log enables: + +- **Version reconstruction**: Any historical version can be reconstructed by replaying deltas +- **Attribution**: Every change is attributed to a specific contributor +- **Audit**: Witness chains prove the integrity of the delta sequence +- **Revert**: A `Deprecation` delta marks a previous delta as superseded + +### 3.3 Evidence Links + +Evidence links are the mechanism by which the encyclopedia distinguishes claims from knowledge. A claim without evidence is a candidate. A claim with evidence is knowledge. + +**Evidence lifecycle**: +1. Contributor submits a delta with one or more evidence links +2. Server verifies evidence link format and contributor authentication +3. Evidence is recorded in the delta's witness chain +4. Other contributors can add corroborating evidence via additional deltas +5. Quality score reflects the evidence density: more verified evidence = higher quality + +## 4. Governance Gates + +Three gates control what enters the encyclopedia and how. + +### 4.1 Gate 1: Identity + +All contributions require API key authentication with contributor pseudonym derivation (same as ADR-060 Section 6). Anonymous users can read but cannot contribute. This prevents Sybil attacks on the knowledge base. + +### 4.2 Gate 2: Evidence + +**For deltas**: Every delta must include at least one evidence link. A correction without evidence is rejected. An extension without evidence is held in a `Proposed` state until evidence is added. + +**For new pages**: A new canonical page requires at least 3 evidence links from independent contributors (not the page creator) before promotion from `Draft` to `Canonical`. This ensures community validation before knowledge becomes authoritative. + +**Evidence verification**: The server does not execute tests or check CI — it verifies that evidence links are well-formed, that the contributor is authenticated, and that the linked artifacts exist (where checkable). Outcome verification is a community responsibility: voters assess whether evidence is credible. + +### 4.3 Gate 3: Consensus + +**Page promotion**: A Draft page becomes Canonical when: +- `quality_score.mean() >= 0.7` (community approval) +- `quality_score.observations() >= 5` (sufficient review) +- `evidence_count >= 3` from `>= 2` distinct contributors + +**Delta acceptance**: A delta is accepted when: +- Contributor is authenticated (Gate 1) +- At least one evidence link is provided (Gate 2) +- Contributor has not been flagged for poisoning (reputation > 0.1) + +**Delta promotion to canonical**: When a delta accumulates sufficient quality votes, the canonical page is updated to incorporate the delta. The old canonical version is preserved in the delta log. + +## 5. Submission Model + +### 5.1 New Users (Reputation < 0.5, Contribution Count < 10) + +New users can: +- Read all pages and delta logs +- Submit deltas to existing pages (with evidence) +- Vote on pages and deltas +- Cannot create new canonical pages + +This prevents low-reputation users from flooding the encyclopedia with low-quality pages while still allowing them to contribute improvements to existing knowledge. + +### 5.2 Established Users (Reputation >= 0.5, Contribution Count >= 10) + +Established users can: +- All new user capabilities +- Create new pages (initially as `Draft`) +- Promote deltas with sufficient evidence + +### 5.3 System Contributors + +System contributors (`is_system: true`, e.g., `ruvector-seed`) can: +- All established user capabilities +- Create pages directly as `Canonical` (for seed data) +- Bypass evidence count requirements (seed data is pre-validated) + +## 6. Delta-Based Editing Protocol + +### 6.1 No Direct Mutation + +The Brainpedia has no "edit page" operation. All modifications are deltas. This is enforced at the API level — the `PUT /v1/pages/{id}` endpoint does not exist. + +### 6.2 Delta Types + +**Correction**: Fixes an error in the canonical page. Requires evidence showing the current content is wrong and the correction is right. + +**Extension**: Adds new information to the canonical page. Requires evidence showing the extension is valid and useful. + +**Evidence**: Adds a new evidence link to an existing claim. No content change — purely strengthens the evidentiary basis. + +**Deprecation**: Marks the canonical page or a specific delta as superseded. Requires evidence showing why the content is no longer valid (e.g., a library version change, a security vulnerability discovered). + +### 6.3 Conflict Resolution + +When multiple deltas target the same section of a canonical page, conflict resolution uses: + +1. **Quality score**: Higher-quality deltas take precedence +2. **Evidence density**: More evidence wins ties +3. **Recency**: Among equal quality and evidence, newer deltas win +4. **Manual resolution**: If automated resolution fails, the page enters `Contested` status and requires a contributor with reputation >= 0.7 to resolve + +## 7.

Answers to Design Questions + +**Q: What is the first domain you want the community Brainpedia to cover?** + +A: Code debugging. Same rationale as ADR-061: highest frequency task, binary success signal, bounded domain, richest existing trajectory data. Debug pages have natural evidence links (TestPass, BuildSuccess) that make the evidence gate practical from day one. + +**Q: Do you want anyone to be able to submit pages, or only submit deltas to existing pages until they earn reputation?** + +A: Deltas only until reputation is earned. New users (composite reputation < 0.5, contribution count < 10) can submit deltas to existing pages but cannot create new pages. This prevents low-reputation flooding while encouraging incremental improvement. Page creation requires demonstrated quality through delta contributions. + +## 12.

Context + +The Shared Brain stores knowledge as embeddings and serves MicroLoRA weights. But the embedding pipeline — structured hash features, LoRA transform, L2 normalization — runs only on the server and in the local MCP client. Browser users, edge appliances, and third-party integrations cannot produce compatible embeddings without reimplementing the pipeline. + +WASM solves this. A signed WASM module that implements feature extraction can run identically in the browser, on the appliance, and on the server. The same bytecode, the same results, cryptographically verified. + +This ADR defines the WASM node architecture: how nodes are built, signed, served, executed, and integrated with the Shared Brain and MicroLoRA pipeline. + +## 2. What WASM Nodes Enable + +### 2.1 Executable Knowledge Pages + +A Brainpedia entry can include a small WASM module that validates, scores, normalizes, or transforms content locally. Knowledge becomes executable, not just readable. + +### 2.2 Deterministic Verification + +The same scoring and feature extraction runs in browser, on the appliance, and on the server with identical results. No "works on my machine" for embeddings. + +### 2.3 Safer Public Compute + +WASM with capability gating lets untrusted users run brain logic without server-side code execution. Pure compute only — no filesystem, no network, no clock access. + +## 3. Node Architecture + +### 3.1 WASM Segment Type + +WASM nodes are signed RVF artifacts. They use the existing RVF segment layout with a new segment type for WASM bytecode. + +A node RVF container contains: +- `MANIFEST (0x05)`: Segment directory +- `META_SEG (0x07)`: Node name, version, description, interface schema +- `WASM_SEG (0x40)`: WASM bytecode (compiled, not WAT) +- `WITNESS_SEG (0x0A)`: SHAKE-256 hash chain (build → sign → publish) +- `CRYPTO_SEG (0x0C)`: Ed25519 signature over all segments + +### 3.2 Hash Choice Consistency + +Two hash functions serve distinct purposes: + +**SHA-256** for HTTP-layer integrity: `X-Node-SHA256` header, `wasm_sha256` in signed manifests, GCS content-addressed storage paths, browser cache keys. SHA-256 is conventional for HTTP caching and CDN infrastructure. + +**SHAKE-256** for RVF witness chains: all WITNESS_SEG entries use SHAKE-256 to maintain consistency with the global RVF witness chain convention (ADR-058). Witness chains are internal to the RVF container format, not exposed via HTTP. + +These do not conflict. SHA-256 is the identity hash visible to HTTP clients. SHAKE-256 is the provenance hash visible to RVF verifiers. + +### 3.3 V1 ABI Specification + +The v1 ABI is `feature_extract` only. `score` and `validate` are deferred to v2 after the determinism guarantee is proven on the simpler single-function interface. Keeping v1 to one function reduces the ABI surface that must be verified across three runtimes. + +**ABI version**: `1` + +**Required exports**: +- `memory`: Linear memory export (must declare a maximum size, rejected if absent or > 16 pages) +- `malloc(size: i32) -> i32`: Allocate memory for input +- `feature_extract_dim() -> i32`: Return the output dimension (must be constant, e.g., 128) +- `feature_extract(in_ptr: i32, in_len: i32, out_ptr: i32) -> i32`: Extract features from text at `in_ptr`/`in_len`, write f32 vector to `out_ptr`, return dimension written + +**Calling convention**: +1. Caller invokes `feature_extract_dim()` to learn output size +2. Caller allocates input buffer via `malloc(input_bytes_len)` +3. Caller writes UTF-8 text into the allocated buffer +4. Caller allocates output buffer via `malloc(dim * 4)` (f32 = 4 bytes) +5. Caller invokes `feature_extract(in_ptr, in_len, out_ptr)` → returns `dim` +6. Caller reads `dim` f32 values directly from `memory` at `out_ptr` + +No global result state. No `read_f32` indirection. The caller owns both input and output pointers. This is the fastest path in both browser and wasmtime. + +**Embedded lookup tables**: Nodes MAY include constant data (token maps, n-gram tables, normalization tables) compiled into the WASM data section. This is fine — the data section is part of the signed bytecode and does not violate the pure-compute constraint. The data section is immutable at runtime. + +### 3.4 Determinism Constraints + +"Bit-identical" is a strong claim. These constraints make it true in practice: + +1. **No f64 in v1 nodes**: All arithmetic uses f32 only. f64 intermediate results are prohibited because fused multiply-add behavior varies across engines for f64. +2. **No SIMD for v1 nodes**: The WASM module must not use the SIMD proposal. SIMD instruction selection and NaN propagation differ across engines. +3. **Deterministic compilation flags**: Nodes must be compiled with `no-fast-math` (Rust: `-C target-feature=-fast-math`, or simply do not opt in). No `-ffast-math`, no `reassociate`, no `reciprocal`. +4. **NaN scrubbing before output**: The last operation before writing each f32 to the output buffer must check for NaN and replace with 0.0f32. This prevents non-deterministic NaN propagation from producing environment-dependent results. +5. **Rounding mode**: IEEE 754 round-to-nearest-even (the WASM default). No explicit rounding mode changes. + +These constraints are verified at publish time where possible (SIMD detection, f64 usage detection via module inspection) and at runtime via conformance test vectors. + +### 3.5 Capability Model + +**V1: zero imports**. The WASM module's import section must be empty. No `env`, no WASI, no custom imports. If the import section is non-empty, the module is rejected at publish time. This is the cleanest rule for pure compute. + +If future nodes require host capabilities (v2+), they are served from a separate endpoint (`/v1/nodes/privileged/`) with explicit capability declarations. Privileged nodes require reputation >= 0.7 to publish. + +### 3.6 Resource Limits + +Resource limits are defined differently per environment because browser Workers lack instruction-level metering. + +**Server and appliance (wasmtime)**: +- Max fuel: calibrated to 25ms on reference CPU (equivalent to ~100M simple instructions) +- Max memory: module must declare maximum <= 16 pages (1MB) +- Epoch interruption as backstop + +**Browser (WebAssembly.instantiate in Worker)**: +- Max wall clock: 25ms (Worker `setTimeout` termination) +- Max input size: 8KB UTF-8 +- Worker isolation: `postMessage` only, no DOM, no fetch, no storage + +**All environments**: +- Max WASM binary size: 1MB +- Max input size: 8KB UTF-8 + +The 25ms budget is aligned across environments. Server fuel is calibrated against reference CPU to approximate 25ms of compute. + +## 4. Signing and Verification + +### 4.1 Canonical Signed Manifest + +The Ed25519 signature covers a canonical binary manifest, not raw JSON. This prevents serialization differences from breaking verification. + +**Signed manifest fields** (fixed-order binary encoding): + +| Field | Type | Bytes | +|-------|------|-------| +| `abi_version` | u8 | 1 | +| `id_len` | u16 LE | 2 | +| `id` | UTF-8 | variable | +| `version_len` | u16 LE | 2 | +| `version` | UTF-8 | variable | +| `dim` | u16 LE | 2 | +| `wasm_sha256` | [u8; 32] | 32 | +| `created_at` | i64 LE (Unix epoch seconds) | 8 | +| `allowed_imports_hash` | [u8; 32] | 32 (SHA-256 of empty string for v1) | +| `compiler_tag_len` | u16 LE | 2 | +| `compiler_tag` | UTF-8 | variable (e.g., "rustc-1.77-wasm32") | + +The signature is `Ed25519.sign(signing_key, manifest_bytes)`. Verification is `Ed25519.verify(public_key, manifest_bytes, signature)`. + +This encoding is deterministic: fixed field order, little-endian integers, explicit length prefixes. No JSON, no CBOR, no ambiguity. + +### 4.2 Verification Flow + +1. Client fetches node metadata (`GET /v1/nodes/{id}/{version}`) +2. Client fetches WASM binary (`GET /v1/nodes/{id}/{version}/node.wasm`) +3. Client computes SHA-256 of WASM bytes, compares to `wasm_sha256` in metadata +4. Client reconstructs manifest bytes from metadata fields +5. Client verifies Ed25519 signature over manifest bytes +6. Client runs conformance test vectors (Section 5) +7. If all pass: instantiate and use. If any fail: reject. + +## 5. Conformance Test Vectors + +Conformance test vectors are first-class policy, not optional documentation. + +### 5.1 Test Vector Format + +Every node's metadata includes a `conformance` object: + +```json +{ + "abi_version": 1, + "dim": 128, + "test_vectors": [ + { + "input": "deadlock tokio spawn rwlock", + "expected_output_sha256": "a1b2c3d4..." + }, + { + "input": "", + "expected_output_sha256": "e5f6a7b8..." + }, + { + "input": "日本語テスト Unicode edge case", + "expected_output_sha256": "c9d0e1f2..." + } + ] +} +``` + +**20 mandatory test vectors** including: +- Empty string +- Single character +- ASCII only +- Unicode (CJK, emoji, combining characters, RTL) +- Maximum length (8KB) +- Repeated tokens +- Whitespace-only +- Mixed case sensitivity test pairs + +### 5.2 Verification Method + +For each test vector: +1. Run `feature_extract` with the input text +2. Read the output f32 vector as raw bytes (little-endian) +3. Compute SHA-256 of the raw output bytes +4. Compare to `expected_output_sha256` + +**Output byte hash, not float comparison.** Float printing can hide differences. Raw byte SHA-256 catches any bit-level divergence. + +### 5.3 Runtime Self-Test + +Every runtime (browser, server, appliance) runs all conformance vectors on first load of a node. If any vector fails, the node is rejected and not used. The server logs conformance failures as security events. + +## 6. Endpoints + +### 6.1 Node Registry + +| Method | Path | Purpose | Auth | +|--------|------|---------|------| +| GET | `/v1/nodes` | List available nodes | Public | +| GET | `/v1/nodes/{id}/{version}` | Get node metadata + conformance vectors | Public | +| GET | `/v1/nodes/{id}/{version}/node.wasm` | Download WASM binary | Public | +| POST | `/v1/nodes` | Publish a new node | Identity + Reputation >= 0.5 | +| DELETE | `/v1/nodes/{id}/{version}` | Revoke a node (original publisher only) | Identity | + +### 6.2 Version Resolution + +There is no `GET /v1/nodes/{id}.wasm` (no implicit "latest"). Clients must specify both `id` and `version`. This prevents supply-chain attacks where a compromised node replaces a trusted version. + +The `GET /v1/nodes` listing includes all versions of all nodes. Clients filter by `id` and select the desired version. + +### 6.3 Response Headers + +**GET /v1/nodes/{id}/{version}/node.wasm**: +- `Content-Type: application/wasm` +- `Cache-Control: public, immutable, max-age=31536000` +- `X-Node-SHA256: {hex-encoded SHA-256 of WASM bytes}` + +Immutable caching is safe because the version is in the path. New versions get new paths. + +### 6.4 Revocation + +`DELETE /v1/nodes/{id}/{version}` marks a node as revoked: +- Only the original publisher can revoke +- Revocation writes an audit record to the witness chain +- WASM bytes remain in storage (for forensic analysis), but the registry stops serving the node +- `GET /v1/nodes/{id}/{version}` returns 410 Gone with a revocation reason +- `GET /v1/nodes/{id}/{version}/node.wasm` returns 410 Gone + +### 6.5 Content-Addressed Storage + +GCS stores WASM binaries by content hash, not by ID: + +``` +gs://ruvector-brain-{region}/nodes/sha256/{hash}.wasm +``` + +The registry maps `(id, version)` → `hash`. Multiple nodes referencing the same bytecode share storage. This makes bytes immutable at the storage layer — the registry controls visibility, not the blob store. + +## 7. Integration with Shared Brain + +### 7.1 Embedding Pipeline in Browser + +The clean split for browser-side semantic search: + +1. **WASM node** (`sona_feature/1.0.0`): runs `feature_extract()` to produce structured hash features (128-dim f32 vector) +2. **Brain API** (`GET /v1/lora/latest`): browser fetches current MicroLoRA weights (2KB JSON) +3. **JS or second WASM node**: applies MicroLoRA transform `output = L2_norm(features + scale * (features @ down) @ up)` +4. **Brain API** (`GET /v1/memories/search`): browser sends the transformed embedding for server-side ranked search + +This gives semantic retrieval in the browser with no heavy model download. + +### 7.2 Brainpedia Integration + +Brainpedia pages (ADR-062) can reference WASM nodes: +- A debug page can link to a `feature_extract` node for domain-specific embedding +- Evidence links can include deterministic WASM validation results +- Pages declare which node version they were indexed with for reproducibility + +### 7.3 Appliance Mode + +Edge appliances run the same WASM nodes as the browser and server: + +1. Load node from local cache or `GET /v1/nodes/{id}/{version}/node.wasm` +2. Run conformance self-test (Section 5.3) +3. Load MicroLoRA weights from local cache or `GET /v1/lora/latest` +4. Run locally: `feature_extract()` → LoRA transform → L2 normalize +5. Search: send embedding to brain, or search local cache + +Offline: steps 1-4 use cached artifacts. Step 5 searches local cache only. + +## 8.

Answers to Design Questions + +**Q: Do you want these WASM nodes to run in browser only, or also on the appliance and server with the same bytecode?** + +A: All three. Browser, appliance, and server execute the same WASM bytecode with bit-identical results, verified by output byte hash comparison across environments. + +**Q: Should nodes be public read like memory search, or should node download be gated because it encodes proprietary heuristics?** + +A: Public read. The proprietary value is in the MicroLoRA weights (learned from quality signals via federation), not in the deterministic feature extraction logic. Gating node download would kill the browser demo path for zero competitive benefit. + +**Q: Do you want the v1 node ABI to support only feature_extract, or do you want score and validate in v1 as well?** + +A: `feature_extract` only for v1. One function, one ABI, one determinism proof. `score` and `validate` are v2 after the cross-platform guarantee is proven on the simpler interface. + +**Q: Should nodes be allowed to include a tiny embedded lookup table, or must they be pure hashing with no internal data beyond constants?** + +A: Lookup tables are allowed. Token maps, n-gram tables, and normalization tables compiled into the WASM data section are fine — the data section is part of the signed bytecode and is immutable at runtime. This is necessary for practical feature extraction. + +## 12.

A bare API with no human-readable entry point creates adoption friction. Developers who visit the domain should immediately understand the system and how to connect. + +Google Cloud Run provides a serverless container platform with automatic TLS, scaling to zero, and custom domain mapping. Custom domains (pi.ruv.io, the Unicode variant) make the brain addressable under a memorable, branded namespace.

The `GcsClient` handles uploads and signed URL generation. + +### 3.4 Landing Page + +The root route (`/`) serves a Three.js Prime Radiant visualization. The page renders an interactive 3D particle system representing the brain's knowledge topology. The aesthetic follows a Foundation (Asimov) sci-fi theme: dark background, blue-white particle fields, Encyclopedia Galactica typography. + +Implementation: `include_str!("../static/index.html")` embeds the HTML at compile time. The handler returns the static content with `Content-Type: text/html; charset=utf-8` and `Cache-Control: public, max-age=300`.

The server itself listens on plain HTTP on port 8080. +2. **CORS**: Explicit origin allowlist (5 origins). No wildcards. +3. **Request body limit**: 1MB via tower-http `RequestBodyLimitLayer`. Prevents memory exhaustion from oversized payloads. +4. **Rate limiting**: `BudgetTokenBucket` per contributor. 100 writes/hour, 1000 reads/hour. Stale buckets evicted every 1000 operations. +5. **Challenge nonces**: Single-use, 5-minute TTL. Required for write operations. +6. **PII stripping**: 12-pattern detection on all incoming text fields (filesystem paths, API keys, tokens, email patterns). +7. **Embedding verification**: NaN, Inf, and magnitude checks on all incoming vectors. +8. **Ed25519 signature verification**: For RVF container and WASM node integrity. +9. **SHAKE-256 witness chains**: For provenance verification on all operations. + +### 4.7 Tracing and Observability + +The server uses `tracing_subscriber` with `EnvFilter` for log level control. Logs are written to stderr (Cloud Run captures stderr as structured logs). The `TraceLayer` middleware logs HTTP request/response metadata including method, path, status code, and latency. + +The health endpoint provides basic liveness/readiness signaling.

Decision + +Adopt a structured publishing pipeline: categorize packages, enforce dependency-ordered publishing, use semver with pre-release tags for unstable packages, and require TypeScript compilation to succeed before any publish.

This prevents `npm install @ruvector/pi-brain` from pulling pre-release versions. + +### 3.5 TypeScript Compilation Requirements + +Every package with TypeScript source must pass these checks before publish: + +1. `tsc --noEmit` succeeds with zero errors +2. `tsc --declaration` generates `.d.ts` files +3. `package.json` includes `types` or `typings` field pointing to the declaration entry point +4. `exports` map includes `types` condition for each entry point + +Packages that fail TypeScript compilation are blocked from publishing. This is enforced by running `npm run build` (which includes `tsc`) as the first step of the publish pipeline. + +## 4. Implementation + +### 4.1 Authentication + +npm authentication uses the `ruvnet` account. Credentials are stored in the project `.env` file and loaded into `~/.npmrc` before publishing. Verify with `npm whoami`. + +The npm token is scoped to the `@ruvector/` scope with publish permissions. Read-only tokens are used in CI for install-only workflows. + +### 4.2 Pre-Publish Checklist + +For each package: + +1. Verify `npm whoami` returns `ruvnet` +2. Run `npm run build` (TypeScript compilation + any bundling) +3. Run `npm test` (all tests must pass) +4. Verify `package.json` version matches the intended release +5. Check that `files` field in `package.json` includes only intended artifacts +6. Run `npm pack --dry-run` to inspect the tarball contents +7. Publish: `npm publish --access public` + +### 4.3 WASM Package Build + +WASM packages require a Rust compilation step before the npm publish: + +1. `cargo build --release --target wasm32-unknown-unknown -p ` +2. `wasm-bindgen` or `wasm-pack` generates the JS/TS bindings +3. Copy generated files into the npm package directory +4. Run TypeScript compilation on the wrapper code +5. Publish as a standard npm package + +### 4.4 Solver Crate Publish Order (Cargo) + +For the Rust solver crates published to crates.io (not npm), the order is: + +1. `ruvector-solver` first (no dependencies) +2. `ruvector-solver-wasm` second (depends on `ruvector-solver`) +3. `ruvector-solver-node` third (depends on `ruvector-solver`) + +Always run `cargo publish --dry-run --allow-dirty` before real publish. `ruvector-profiler` has `publish = false` and is intentionally not publishable. + +### 4.5 Version Coordination + +When a breaking change occurs in a Tier 1 package, all dependent packages must be updated and republished. The procedure is: + +1. Publish the updated Tier 1 package with the new major/minor version +2. Update `package.json` in all dependent packages to reference the new version +3. Run `npm install` in each dependent package to verify resolution +4. Run tests in each dependent package +5. Publish dependent packages in tier order + +For non-breaking changes (patch versions), only the changed package needs republishing. Dependents using caret ranges (`^x.y.z`) automatically resolve the new patch. + +### 4.6 Package.json Standards + +All `@ruvector/` packages must include: + +```json +{ + "name": "@ruvector/", + "version": "x.y.z", + "license": "MIT OR Apache-2.0", + "repository": { + "type": "git", + "url": "https://github.com/ruvnet/ruvector" + }, + "engines": { "node": ">=18" }, + "type": "module", + "main": "./dist/index.js", + "types": "./dist/index.d.ts", + "exports": { + ".": { + "types": "./dist/index.d.ts", + "import": "./dist/index.js" + } + }, + "files": ["dist/", "README.md", "LICENSE"] +} +``` + +The `files` field is explicitly set to prevent accidental inclusion of source maps, test fixtures, `.env` files, or other development artifacts in the published tarball. + +### 4.7 CI Integration + +The publish pipeline runs in GitHub Actions: + +1. **Trigger**: Manual workflow dispatch with package name and version as inputs +2. **Auth**: npm token from GitHub Secrets, loaded into `~/.npmrc` +3. **Build**: `npm run build` in the package directory +4. **Test**: `npm test` in the package directory +5. **Dry run**: `npm pack --dry-run` to verify tarball contents +6. **Publish**: `npm publish --access public` (or `--tag alpha/beta` for pre-releases) +7. **Verify**: `npm view @ruvector/ version` confirms the published version + +The workflow rejects publishes if the version already exists on the registry (npm returns 403 for duplicate versions). + +## 5. Consequences + +### Positive + +- **No broken installs**: Dependency-ordered publishing ensures consumers never pull a package whose dependencies are not yet available +- **Safe defaults**: Pre-release tags prevent accidental production use of unstable versions +- **Type safety**: Mandatory TypeScript compilation catches type errors before they reach consumers +- **Single account**: All packages under `ruvnet` with `@ruvector/` scope provides consistent ownership and discoverability +- **Explicit file lists**: The `files` field prevents credential leaks and keeps tarballs small + +### Negative + +- **Manual coordination**: Publishing 48+ packages in order requires discipline. Automation (a publish script that resolves the dependency graph and publishes in topological order) is deferred but recommended. +- **WASM build complexity**: WASM packages require both Rust and Node.js toolchains. Build failures in either chain block the publish. +- **ESM-only**: All packages use `"type": "module"`. CommonJS consumers must use dynamic `import()` or a bundler. This is a deliberate choice — the ecosystem is moving to ESM and dual-packaging adds complexity. + +### Neutral + +- The `@ruvector/pi-brain` package combining CLI + SDK + MCP in one package increases the install size but simplifies the getting-started experience. Users who only need the SDK can tree-shake unused CLI code. +- Node.js >= 18 is required. This matches the current LTS baseline and enables native `fetch`, `structuredClone`, and other modern APIs. diff --git a/docs/adr/ADR-066-sse-mcp-transport.md b/docs/adr/ADR-066-sse-mcp-transport.md new file mode 100644 index 000000000..d47169107 --- /dev/null +++ b/docs/adr/ADR-066-sse-mcp-transport.md @@ -0,0 +1,223 @@ +# ADR-066: SSE MCP Transport + +**Status**: Accepted, Deployed +**Date**: 2026-02-28 +**Authors**: RuVector Team +**Deciders**: ruv +**Supersedes**: N/A +**Related**: ADR-059 (Shared Brain Google Cloud), ADR-060 (Shared Brain Capabilities), ADR-062 (Brainpedia), ADR-063 (WASM Executable Nodes), ADR-064 (Pi Brain Infrastructure) + +## 1.

This works well for local sessions but cannot serve remote clients — browsers, CI pipelines, or Claude Code sessions that want to connect without installing a local binary. + +MCP over Server-Sent Events (SSE) solves this.

Instead, they are proxied to the server's own REST API via HTTP loopback. This ensures that: + +1. All existing middleware (CORS, rate limiting, body size limits, tracing) applies uniformly +2.

All decisions are recorded in a cryptographic witness chain. Contributor authentication uses SHAKE-256 pseudonym derivation, and access is rate-limited via BudgetTokenBucket. + +## 2. Decision + +Implement `mcp-gate` as a standalone MCP stdio server that wraps the existing `cognitum-gate-tilezero` gate. Use SHAKE-256 for pseudonym derivation (consistent with the brain server's authentication scheme), challenge nonces for replay protection, and BudgetTokenBucket for rate limiting. All gate decisions produce cryptographically chained witness receipts. + +## 3. Architecture + +### 3.1 Crate Structure + +``` +crates/mcp-gate/ + src/ + lib.rs -- Public API, re-exports + main.rs -- Entry point (McpGateServer::run_stdio) + server.rs -- MCP protocol handler (JSON-RPC over stdio) + tools.rs -- Tool implementations (permit, receipt, replay) + types.rs -- Request/response types, JSON-RPC types + Cargo.toml +``` + +The crate depends on: +- `cognitum-gate-tilezero`: The coherence gate engine (TileZero) +- `tokio`: Async runtime for stdio processing +- `serde` / `serde_json`: JSON-RPC serialization +- `thiserror`: Error types + +### 3.2 MCP Tools + +**`permit_action`**: Request permission for an action. The gate evaluates three witnesses: + +| Witness | What it measures | Output | +|---------|-----------------|--------| +| Structural | Mincut graph analysis of the action's connectivity | `cut_value`, `partition` status, critical edges | +| Predictive | Conformal prediction set for the action's outcome | `set_size`, `coverage` target | +| Evidential | Anytime-valid e-process accumulation | `e_value`, `verdict` (accept/continue/reject) | + +Returns one of three decisions: +- **Permit**: Action allowed. Returns a `PermitToken` (base64-encoded, time-bounded) and a witness receipt. +- **Defer**: Action escalated. Returns escalation info (reason, suggested reviewer) and a witness receipt. +- **Deny**: Action blocked. Returns denial reason and a witness receipt. + +**`get_receipt`**: Retrieve a witness receipt by sequence number. Each gate decision produces a receipt containing the decision, timestamp, witness summary, and a hash linking to the previous receipt. The chain is cryptographic — tampering with any receipt breaks the chain. + +**`replay_decision`**: Deterministically replay a past decision given the same inputs and state snapshot. Optionally verifies the hash chain integrity up to the replayed sequence number. Returns whether the replayed decision matches the original. + +### 3.3 SHAKE-256 Pseudonym Derivation + +Contributor pseudonyms are derived from API keys using SHAKE-256, identical to the brain server (ADR-059, ADR-060): + +```rust +pub fn from_api_key(api_key: &str) -> AuthenticatedContributor { + let mut hasher = Shake256::default(); + hasher.update(b"ruvector-brain-pseudonym:"); + hasher.update(api_key.as_bytes()); + let mut reader = hasher.finalize_xof(); + let mut buf = [0u8; 16]; + reader.read(&mut buf); + let pseudonym = hex::encode(buf); + // ... +} +``` + +This produces a 32-character hex pseudonym (128-bit) that: +- Is deterministic: same API key always produces the same pseudonym +- Is irreversible: the API key cannot be recovered from the pseudonym +- Uses a domain-separated prefix (`ruvector-brain-pseudonym:`) to prevent cross-system correlation + +### 3.4 Challenge Nonce Replay Protection + +Write operations (including `permit_action`) require a challenge nonce to prevent replay attacks: + +1. Client calls `GET /v1/challenge` to receive a fresh nonce +2. Server generates a random nonce, stores it with a 5-minute TTL +3. Client includes the nonce in the write request +4. Server verifies the nonce exists and has not expired +5. Server consumes the nonce (single-use) + +Nonces are stored in a `NonceStore` backed by a `DashMap` with periodic TTL eviction. + +### 3.5 Rate Limiting + +The `BudgetTokenBucket` pattern (shared with the brain server) provides per-contributor rate limiting: + +```rust +pub struct RateLimiter { + write_buckets: DashMap, + read_buckets: DashMap, + write_limit: u32, // 100 writes/hour + read_limit: u32, // 1000 reads/hour + window: Duration, // 1 hour +} +``` + +Each contributor (identified by pseudonym) gets independent token buckets for reads and writes. Buckets refill at window boundaries. Stale buckets (unused for 2 windows) are periodically evicted to prevent unbounded memory growth. The cleanup runs every 1000 operations. + +### 3.6 Multi-Factor Reputation Scoring + +The reputation system gates access levels: + +``` +composite = accuracy^2 * uptime * stake_weight +``` + +| Factor | Measurement | Update | +|--------|-------------|--------| +| `accuracy` | Bayesian Beta(1,1) prior, updated from vote outcomes | `(upvotes+1)/(upvotes+downvotes+2)` after min 5 observations | +| `uptime` | EMA of activity frequency | `uptime = 0.95 * uptime + 0.05` per contribution | +| `stake_weight` | Fixed at 1.0 for v1 | Future: based on contribution volume | + +- New contributors start at composite ~0.1. Their gate requests are weighted 10x less. +- Contributors with composite < 0.1 are flagged as potential poisoners and their permit requests are auto-denied. +- Inactivity decay: `accuracy *= 0.95^months_inactive`, `uptime *= 0.90^months_inactive`. + +### 3.7 Contributor Pseudonym Revocation + +A contributor can be revoked by setting their reputation below the poisoning threshold (0.1). The `check_poisoning_penalty` function triggers when: +- The contributor has >= 5 downvotes on their contributions +- Their quality score falls below 0.2 + +Once penalized, the contributor's pseudonym is effectively revoked — all gate requests return Deny. The pseudonym remains in the system for audit purposes. The contributor can only recover by generating a new API key (and thus a new pseudonym), starting at the cold-start reputation of 0.1. + +## 4. Implementation + +### 4.1 Server Entry Point + +```rust +let server = McpGateServer::new(); +server.run_stdio().await.expect("Server failed"); +``` + +The server reads JSON-RPC requests from stdin, dispatches to tool handlers, and writes responses to stdout.

Consequences + +### Positive + +- **Standard MCP interface**: Any MCP-compatible client (Claude Code, custom agents) can request gate permits without custom integration +- **Cryptographic audit trail**: Every decision is chained. Tampering is detectable. Replays are deterministic. +- **Shared auth scheme**: SHAKE-256 pseudonym derivation is identical between `mcp-gate` and `mcp-brain-server`, enabling cross-system contributor identity without sharing API keys +- **Defense in depth**: Rate limiting + nonce replay protection + reputation gating + cryptographic witnesses form layered protection + +### Negative + +- **Stdio only**: The MCP gate is stdio-based, not SSE. It must run as a local process. Remote access requires wrapping in a network transport (deferred). +- **Stateful**: The TileZero gate accumulates witness receipts in memory. Long-running sessions with many decisions grow linearly. Persistence to disk is deferred. + +### Neutral + +- The three-witness model (structural, predictive, evidential) is inherited from `cognitum-gate-tilezero`. The MCP gate does not add new decision logic — it provides protocol access to existing capabilities. +- Pseudonym revocation is soft (reputation penalty) not hard (key revocation). A determined attacker can generate new API keys. This is acceptable because cold-start reputation (0.1) limits the blast radius of new pseudonyms. diff --git a/docs/adr/ADR-068-domain-expansion-transfer-learning.md b/docs/adr/ADR-068-domain-expansion-transfer-learning.md new file mode 100644 index 000000000..48d1056a6 --- /dev/null +++ b/docs/adr/ADR-068-domain-expansion-transfer-learning.md @@ -0,0 +1,239 @@ +# ADR-068: Domain Expansion Transfer Learning + +**Status**: Accepted, Implemented +**Date**: 2026-02-28 +**Authors**: RuVector Team +**Deciders**: ruv +**Supersedes**: N/A +**Related**: ADR-057 (Federated RVF Transfer Learning), ADR-060 (Shared Brain Capabilities), ADR-061 (Reasoning Kernel Architecture) + +## 1. Context + +The Shared Brain (ADR-060) enables cumulative learning within a single domain. But real intelligence growth appears when knowledge from one domain accelerates learning in a different domain. A debugging heuristic from Rust should inform debugging in TypeScript. A planning strategy from infrastructure deployment should transfer to release management. + +The `ruvector-domain-expansion` crate (`crates/ruvector-domain-expansion/`) implements cross-domain transfer learning using Meta Thompson Sampling with compact prior transfer. The core insight: true generalization is measured by whether Domain 2 converges faster than Domain 1 did, given priors extracted from Domain 1. If cost curves compress with each new domain, general problem-solving capability is increasing. + +## 2. Decision + +Implement a two-layer architecture: a policy learning layer (Meta Thompson Sampling with Beta priors) that chooses strategies across context buckets, and an operator layer (deterministic domain kernels) that generates tasks, evaluates solutions, and produces embeddings. Transfer happens through compact priors — not raw trajectories. Verification requires dual conditions: improved target AND not regressed source. + +## 3. Architecture + +### 3.1 Two-Layer Design + +**Policy Learning Layer** (`MetaThompsonEngine`): +- Maintains per-domain, per-bucket, per-arm Beta distribution parameters +- Selects strategy arms via Thompson Sampling (sample from posterior, pick highest) +- Records outcomes as Bayesian posterior updates +- Extracts compact `TransferPrior` summaries for cross-domain shipping +- Seeds new domains with dampened priors from source domains + +**Operator Layer** (Domain implementations): +- `RustSynthesisDomain`: Generates Rust function synthesis tasks, evaluates correctness +- `PlanningDomain`: Generates multi-step planning tasks with dependencies and resources +- `ToolOrchestrationDomain`: Generates multi-tool coordination tasks +- Each domain implements `generate_tasks()`, `evaluate()`, `embed()`, `reference_solution()` + +### 3.2 Meta Thompson Sampling + +Standard Thompson Sampling maintains a Beta(alpha, beta) distribution per arm and samples to select. Meta Thompson Sampling extends this across domains: + +1. **Train on Domain 1**: Record outcomes, accumulate per-bucket posteriors +2. **Extract TransferPrior**: Filter to buckets with sufficient evidence (alpha + beta > 12), package as a compact summary +3. **Initialize Domain 2**: Seed with dampened priors from Domain 1 using sqrt-scaling +4. **Train on Domain 2**: The transferred priors give Domain 2 a head start +5. **Measure acceleration**: Compare convergence cycles with vs without transfer + +### 3.3 Dampened Sqrt-Scaling Priors + +When transferring priors from source to target, raw posteriors would over-commit the target to source-domain strategies. Dampening uses sqrt-scaling to reduce confidence while preserving the mean: + +```rust +let dampened = BetaParams { + alpha: 1.0 + (params.alpha - 1.0).sqrt(), + beta: 1.0 + (params.beta - 1.0).sqrt(), +}; +``` + +Example: A source prior of Beta(81, 21) (mean=0.79, very confident) becomes Beta(1 + sqrt(80), 1 + sqrt(20)) = Beta(9.94, 5.47) (mean=0.64, much less confident). The target retains the directional signal (strategy A is probably better than strategy B) but has enough uncertainty to adapt if the source signal does not transfer. + +Cost EMA priors are transferred with pessimistic scaling (1.5x) to avoid under-budgeting in an unfamiliar domain. + +### 3.4 TransferPrior and PolicyKernel RVF Segments + +Transfer artifacts are serialized as RVF segments for the Shared Brain: + +| Segment | Type Code | Content | +|---------|-----------|---------| +| `TransferPrior` | `0x30` | Per-bucket, per-arm Beta parameters + cost EMA priors + training cycle count + witness hash | +| `PolicyKernel` | `0x31` | Policy knobs (skip mode, prepass flag, speculation threshold) + holdout scores + fitness | +| `CostCurve` | `0x32` | Ordered data points (cycle, accuracy, cost_per_solve, robustness, violations) + convergence thresholds | + +The `rvf_bridge` module (enabled with `feature = "rvf"`) handles serialization via wire-format wrappers that convert `HashMap` to `Vec<(K, V)>` for JSON-safe encoding. SHAKE-256 witness chains cover the entire serialization for integrity. + +### 3.5 CostCurve Acceleration Tracking + +The `AccelerationScoreboard` tracks convergence speed across domains: + +```rust +pub struct CostCurvePoint { + pub cycle: u64, + pub accuracy: f32, + pub cost_per_solve: f32, + pub robustness: f32, + pub policy_violations: u32, + pub timestamp: f64, +} +``` + +Convergence thresholds define the acceptance test: +- Target accuracy: 0.95 +- Target cost per solve: 0.01 +- Target robustness: 0.90 +- Max policy violations: 0 + +A domain has converged when all four thresholds are simultaneously met. The acceleration factor is `baseline_cycles / transfer_cycles` — the ratio of how many cycles the target took without transfer vs with transfer. An acceleration factor > 1.0 means transfer helped. + +### 3.6 TransferVerification + +The verification protocol enforces the generalization rule: + +```rust +impl TransferVerification { + pub fn verify( + source: DomainId, + target: DomainId, + source_before: f32, + source_after: f32, // must not regress beyond 0.01 tolerance + target_before: f32, + target_after: f32, // must improve + baseline_cycles: u64, + transfer_cycles: u64, + ) -> Self { + let improved_target = target_after > target_before; + let regressed_source = source_after < source_before - 0.01; + let promotable = improved_target && !regressed_source; + let acceleration_factor = baseline_cycles as f32 / transfer_cycles as f32; + // ... + } +} +``` + +A transfer delta is promotable only when: +1. `improved_target`: The target domain's score increased after applying the transfer +2. `NOT regressed_source`: The source domain's score did not decrease beyond a 0.01 tolerance + +Both conditions must hold.

These serve two purposes: +1. Negative examples for future strategy selection (avoid strategies that produced poor results in similar contexts) +2. Diagnostic data for understanding domain boundaries where transfer fails + +## 5. Consequences + +### Positive + +- **Measurable generalization**: The acceleration scoreboard provides a quantitative answer to "is the system getting smarter across domains?" +- **Safe transfer**: Dampened priors prevent over-commitment to source-domain strategies. Dual verification prevents source regression. +- **Compact transfer artifacts**: TransferPriors are small (per-bucket Beta parameters, not raw trajectories). They serialize to a few KB as RVF segments. +- **Composable meta-learning**: Regret tracking, plateau detection, Pareto optimization, and curiosity bonuses layer independently and can be enabled/disabled per deployment. + +### Negative + +- **Three domains only**: The current implementation has three hard-coded domains (Rust synthesis, planning, tool orchestration). Adding new domains requires implementing the `Domain` trait and registering with the engine. +- **No online transfer**: Transfer is initiated manually via `initiate_transfer()`. Automatic transfer triggering (e.g., when a domain's cost curve plateaus) is deferred. +- **Population size fixed**: The population search uses 8 kernels. Tuning population size requires code changes. + +### Neutral + +- The 0.01 tolerance on source regression allows minor noise in evaluation scores without blocking transfers. This is a practical trade-off — evaluation noise from holdout sampling can cause small score fluctuations that are not true regressions. +- Counterexamples grow unboundedly per domain.

When multiple edge nodes encounter the same brain memory during task execution, their independent quality assessments converge via entropy consensus. The consensus result feeds back to the brain as a distributed Bayesian update, supplementing individual `brain_vote` calls with collective judgment. + +### 4.4 RAC Coherence Integration + +Edge-net's adversarial coherence engine (RAC, 12 axioms) protects the integrity of shared patterns. When edge nodes share patterns derived from brain knowledge, RAC ensures: + +- **Axiom 6 (Disagreement is signal)**: Conflicting edge assessments of brain knowledge trigger investigation +- **Axiom 9 (Quarantine is mandatory)**: Suspicious patterns from untrusted nodes are quarantined before reaching the brain +- **Axiom 11 (Equivocation detectable)**: Merkle tree audit trail prevents nodes from submitting contradictory results + +## 5. Distributed Compute Tasks + +Brain operations that can be farmed out to edge-net WASM nodes: + +### 5.1 Vector Similarity Search + +The brain's HNSW index can be partitioned across edge nodes. Each node holds a shard of the index and executes approximate nearest-neighbor queries locally.

The MicroLoRA transform adds learned semantic refinement. Both stages can run on edge nodes: + +- **Stage 1 (lexical)**: `structured_hash_features()` is pure computation on text input, runs entirely in WASM +- **Stage 2 (LoRA transform)**: MicroLoRA forward pass with rank 1-16, `<50us` for rank-1 on edge-net's `AdapterPool` +- **Consensus weights**: Edge nodes pull the latest LoRA consensus from the brain, ensuring embedding consistency + +### 5.3 MinCut Graph Partitioning + +The brain's `SubpolynomialMinCut` algorithm for knowledge graph partitioning can be parallelized: + +- **Partition strategy**: Each edge node processes a subgraph assigned by the brain +- **Merge**: The relay collects partial cuts and the brain computes the global minimum +- **Use case**: When the knowledge graph grows large, rebalancing partitions benefits from distributed compute + +### 5.4 Federated LoRA Training + +Edge-net already implements federated learning with Byzantine-tolerant gradient gossip (`GradientGossip` in `edge-net/src/ai/federated.rs`): + +- **TopK sparsification**: 90% gradient compression reduces bandwidth +- **Byzantine detection**: 2-sigma outlier exclusion removes malicious gradients +- **Differential privacy**: Gaussian noise injection protects individual contributions +- **Integration**: Edge nodes train MicroLoRA weights on local task patterns; brain aggregates via reputation-weighted federated averaging + +### 5.5 Quality Voting + +Distributed Bayesian quality updates from edge nodes: + +- Each edge node that uses a brain memory during task execution records success/failure +- Results are aggregated via entropy consensus across participating edge nodes +- The consensus vote is submitted to the brain as a weighted Bayesian update +- Brain's quality gating (auto-archive at `quality_score.mean() < 0.3` after 5 observations) benefits from higher observation counts + +## 6. Security Model + +### 6.1 Identity and Authentication + +| Layer | Mechanism | Purpose | +|-------|-----------|---------| +| Edge node identity | Pi-Key Ed25519 (314-bit) | Per-node cryptographic identity | +| Brain contributor pseudonym | SHAKE-256 of Pi-Key public key | Brain-compatible attribution | +| Operation signing | Ed25519 signatures on task results | Non-repudiation | +| Brain witness chains | Append-only signed chain | Audit trail for all contributions | + +### 6.2 Byzantine Fault Tolerance + +Edge nodes are untrusted by default. The system provides multiple layers of protection: + +- **Gradient poisoning**: `ByzantineDetector` in federated.rs excludes gradients beyond 2 standard deviations from the reputation-weighted mean +- **Result validation**: Brain cross-checks edge search results against local index for random samples (probabilistic verification) +- **Reputation decay**: Nodes that submit invalid results lose reputation, reducing their influence on future aggregation +- **RAC quarantine**: Patterns from low-reputation nodes enter quarantine before affecting brain state + +### 6.3 Sybil Resistance + +Sybil resistance uses layered defenses instead of high staking barriers, ensuring the network remains accessible to newcomers while protecting against abuse: + +| Defense Layer | Mechanism | Purpose | +|---------------|-----------|---------| +| Proof of Work | First contribution requires completing 1 compute task | Proves real compute capacity; blocks zero-cost identity creation | +| Rate Limiting | 100 writes/hour per identity | Bounds the damage any single Sybil identity can cause | +| Quality Gating | Shared knowledge must pass RAC coherence check (score > 0.5) | Prevents low-quality spam from polluting the brain | +| Progressive Trust | Higher reputation tiers unlock higher rate limits and priority | Long-term good behavior is expensive to fake across many identities | +| Reputation Decay | 1% decay per epoch (see `ReputationCurve.apply_decay()`) | Abandoned Sybil identities lose influence automatically | + +Staking remains available as an optional mechanism (see Section 8.3) but is not required for basic participation. Nodes that submit invalid results (as detected by probabilistic verification or Byzantine detection) have their reputation slashed, which is more effective than financial slashing alone because reputation takes sustained effort to rebuild. + +### 6.4 Data Privacy + +- Edge nodes receive only the data needed for their assigned subtask (need-to-know) +- Search queries are decomposed so no single edge node sees the full query context +- LoRA gradients are protected by differential privacy (Gaussian noise with configurable epsilon) +- The relay strips personally identifiable metadata before forwarding to edge nodes + +## 7. API Bridge Design + +Three integration options, ordered by implementation simplicity: + +### Option A: Direct REST (recommended for Phase 1) + +Edge-net nodes call the brain's REST API directly through the relay proxy. + +``` +Edge Node --[WS]--> Relay --[HTTPS]--> pi.ruv.io/v1/memories/search + pi.ruv.io/v1/memories (POST) + pi.ruv.io/v1/lora/latest +``` + +- Simplest to implement: relay proxies HTTP requests with Pi-Key authentication headers +- Each edge node's requests are independently rate-limited at the relay +- No persistent connection required between relay and brain + +### Option B: Relay-Proxied Batch (recommended for Phase 2) + +The relay batches requests from multiple edge nodes into bulk brain API calls. + +``` +Edge Nodes --[WS]--> Relay --[HTTPS bulk]--> pi.ruv.io/v1/batch +``` + +- Reduces brain API call count when many edge nodes query simultaneously +- Relay aggregates search queries, deduplicates, and fans results back to requesting nodes +- Requires a `/v1/batch` endpoint on the brain (new development) + +### Option C: SSE MCP Bridge (recommended for Phase 3) + +The relay maintains a persistent SSE MCP session with the brain and multiplexes edge node requests over it. + +``` +Edge Nodes --[WS/MCP]--> Relay --[SSE MCP]--> pi.ruv.io/sse +``` + +- Full tool access: all 22 brain MCP tools available to edge nodes +- Persistent connection amortizes SSE setup overhead +- Relay maintains a single SSE session per brain region, multiplexing edge requests +- Requires MCP session management in the relay (handles reconnection, session affinity) + +## 8. Economic Model + +The economic model is designed around two principles: **accessible** (no barriers to entry) and **sustainable** (finite supply with controlled inflation). The previous model required 10-200 rUv staking to participate, creating a chicken-and-egg problem for new users. The revised model eliminates cost barriers entirely and uses contribution rewards to bootstrap the economy. + +### 8.1 Free-to-Read, Earn-to-Write + +All read operations are FREE. No rUv cost, no staking requirement. This removes the single biggest barrier to adoption. Write operations are also free to perform but earn rUv rewards when quality thresholds are met. + +| Operation | Cost | Reward | Conditions | +|-----------|------|--------|------------| +| Search brain | FREE | 0 rUv | -- | +| Get brain status | FREE | 0 rUv | -- | +| List memories | FREE | 0 rUv | -- | +| Share knowledge | FREE | 2 rUv | Quality score > 0.5 after RAC review | +| Vote on quality | FREE | 0.1 rUv | Must have completed >= 1 task | +| Generate embedding | FREE | 1 rUv | Result passes hash verification | +| LoRA gradient | FREE | 5 rUv | Gradient passes Byzantine detection | +| WASM compute | FREE | 0.5-3 rUv | Based on compute time and success rate | + +Implementation reference: rewards are credited via `WasmCreditLedger.credit()` in `examples/edge-net/src/credits/mod.rs`. The ledger's CRDT merge (`WasmCreditLedger.merge()`) ensures consistency across P2P nodes. + +### 8.2 Contribution Curve (Revised) + +The contribution curve rewards early adopters without being extractive. The formula is updated from the existing `ContributionCurve` in `examples/edge-net/src/credits/mod.rs`: + +``` +multiplier = FLOOR + (MAX_BONUS - FLOOR) * e^(-network_compute / DECAY_CONSTANT) +``` + +| Parameter | Old Value | New Value | Rationale | +|-----------|-----------|-----------|-----------| +| `MAX_BONUS` | 10x | 5x | Still rewards early adopters, less extractive | +| `FLOOR_MULTIPLIER` | 1x (implicit) | 0.5x | Even mature network still pays something | +| `DECAY_CONSTANT` | 1,000,000 CPU-hours | 1,000,000 CPU-hours | Unchanged | + +At genesis (0 compute-hours), multiplier is 5x. As total network compute grows, multiplier decays toward 0.5x. This means: + +| Network Compute | Multiplier | +|----------------|------------| +| 0 hours (genesis) | 5.0x | +| 100K hours | 4.6x | +| 500K hours | 2.9x | +| 1M hours | 1.9x | +| 5M hours | 0.5x | + +The `ContributionCurve::current_multiplier()` implementation must be updated to use the revised constants. The `FLOOR_MULTIPLIER` ensures contributors always earn something, even when the network is mature. + +### 8.3 Reputation Tiers (Revised) + +Reputation tiers use the existing `ReputationTier` enum from `examples/edge-net/src/economics/reputation.rs` but add a Newcomer tier and make staking optional: + +| Tier | Score | Reward Mult | Staking Required | Access | +|------|-------|-------------|-----------------|--------| +| Newcomer | 0-10 | 0.5x | None | Read-only free, writes earn at 0.5x | +| Bronze | 10-25 | 1.0x | 0 rUv | Full read/write, standard rewards | +| Silver | 25-50 | 1.1x | 10 rUv (optional) | Priority task allocation | +| Gold | 50-75 | 1.25x | 50 rUv (optional) | Price discounts via `ReputationCurve.discount()`, priority | +| Platinum | 75-100 | 1.5x | 100 rUv (optional) | Max discounts, governance voting weight | + +Key changes from the previous model: +- **Staking is OPTIONAL.** It provides benefits (price discounts, governance weight) but is not required for basic participation. This eliminates the chicken-and-egg problem where new users need rUv to participate but cannot earn rUv without participating. +- **Newcomer tier added.** Score 0-10 earns at 0.5x rate, providing immediate earning capability. +- **Reward multipliers** are applied via `ReputationTier::reward_multiplier()` which already implements the 1.0x/1.1x/1.25x/1.5x tiers in the codebase. + +### 8.4 Halving Schedule + +Brain rewards halve every 100K brain operations (cumulative across all nodes). This creates a Bitcoin-like deflationary schedule that ensures finite total rUv supply: + +| Epoch | Cumulative Operations | Base Reward Multiplier | +|-------|-----------------------|----------------------| +| 0 | 0 - 100K | 1.0x | +| 1 | 100K - 200K | 0.5x | +| 2 | 200K - 400K | 0.25x | +| 3 | 400K - 800K | 0.125x | +| N | ... | 1/(2^N)x | + +The halving multiplier stacks with the contribution curve and reputation tier multipliers: + +``` +effective_reward = base_reward * contribution_multiplier * tier_multiplier * halving_multiplier +``` + +This creates urgency for early participation (higher halving multiplier) without the aggressive 10x genesis bonus that the old contribution curve provided. + +### 8.5 Protocol Budget + +Each epoch has a fixed rUv budget to prevent runaway inflation: + +| Parameter | Value | Rationale | +|-----------|-------|-----------| +| Initial epoch budget | 1,000,000 rUv | Sufficient for ~200K reward operations at average 5 rUv | +| Budget carry-over | Yes | Unspent budget rolls to next epoch | +| Budget exhaustion behavior | Rewards pause until next epoch | Hard cap prevents inflation | +| Epoch duration | 7 days or 100K operations, whichever comes first | Bounds both time and volume | + +The protocol fund is managed by `EconomicEngine.get_protocol_fund()`. The `ComputeAMM` in `examples/edge-net/src/economics/amm.rs` provides secondary revenue through trading fees (0.3%-3% dynamic fee based on pool utilization) that supplement the protocol budget after the bootstrap phase. + +### 8.6 Sybil Resistance (Economic) + +Instead of requiring high staking barriers (the old model required 10-200 rUv to participate), the revised model uses layered economic defenses: + +| Defense | Mechanism | Implementation | +|---------|-----------|----------------| +| Proof of Work | First contribution requires completing 1 compute task | Proves real compute capacity; blocks zero-cost Sybil creation | +| Rate limiting | 100 writes/hour per identity | Bounds damage per identity; implemented at relay level | +| Quality gating | Shared knowledge must pass RAC coherence check | `AdversarialCoherence` score > 0.5 required | +| Progressive trust | Higher tiers unlock higher rate limits and priority | `ReputationCurve.select_nodes_for_task()` weights by reputation | +| Reputation cost | Reputation takes sustained effort to build (diminishing returns in `record_task()`) | More expensive to maintain many Sybil identities than one real identity | + +### 8.7 Sustainability Analysis + +The revised model is sustainable because total rUv supply converges: + +**Finite supply proof.** With halving schedule and fixed epoch budget: +- Epoch 0: up to 1,000,000 rUv minted +- Epoch 1: up to 500,000 rUv +- Epoch N: up to 1,000,000 / 2^N rUv +- Total maximum supply = 1,000,000 * sum(1/2^N for N=0..inf) = 2,000,000 rUv + +**Revenue sources by phase:** + +| Phase | Duration | Primary Revenue | Secondary Revenue | +|-------|----------|----------------|-------------------| +| Bootstrap (0-10K nodes) | Months 1-6 | Protocol fund subsidy | None | +| Growth (10K-100K nodes) | Months 6-18 | Protocol fund + AMM fees | Brain API consumer payments | +| Self-sustaining (100K+ nodes) | Month 18+ | AMM fees + consumer payments | Liquidity provider fees | + +**Deflationary pressure.** As brain knowledge grows, rUv utility increases (more valuable knowledge to access, more compute tasks available). The AMM's constant-product formula (`x * y = k` in `ComputeAMM`) ensures that as demand for compute grows, the rUv price of compute increases, creating natural deflationary pressure. + +**Protocol fund sufficiency.** At 2,000,000 rUv maximum supply and projected 50K operations/month at maturity, the protocol fund sustains rewards for 24+ months even without secondary revenue. AMM fees (0.3%-3% of all swaps, tracked via `ComputeAMM.fees_collected`) provide a sustainable revenue stream after bootstrap. + +## 9.

The brain client validates TLS certificates. No HTTP fallback. + +### 6.3 Dependency Isolation + +Brain and edge dependencies are optional peers, not bundled. This prevents supply chain attacks through transitive dependencies from affecting users who only use the core vector database. + +## 7. Versioning + +The `ruvector` CLI version is independent of the brain and edge package versions. The CLI detects compatible version ranges at runtime: + +```typescript +const pkg = await import('@ruvector/pi-brain/package.json'); +if (!semver.satisfies(pkg.version, '>=0.1.0')) { + console.warn(chalk.yellow(`pi-brain ${pkg.version} may not be compatible`)); +} +``` + +## 8.

Migration Path + +### Phase 1: CLI Extension (1 week) +Add command groups to `bin/cli.js`. Wire `brain` commands to `@ruvector/pi-brain`. Add `identity` commands with key generation and SHAKE-256 derivation. + +### Phase 2: Edge Integration (1 week) +Add `edge` commands. Create Node.js adapter for `@ruvector/edge-net` (which targets browsers). Implement headless join for server-side compute contribution. + +### Phase 3: MCP Proxy (1 week) +Add `mcp start` with stdio and SSE transport support. Replace `cargo run -p mcp-brain` as the recommended MCP setup for non-Rust users. + +### Phase 4: Publish (1 week) +Bump `ruvector` to 0.2.0. Update README. Publish `@ruvector/pi-brain` and ensure version compatibility. Update landing page docs. + +## 10. Consequences + +### Positive +- Single entry point: `npx ruvector` provides access to vector DB, shared brain, edge compute, and MCP +- Progressive adoption: core package stays lightweight, features opt-in via peer deps +- No Rust required: `npx ruvector mcp start` replaces `cargo run -p mcp-brain` +- Unified identity: one π key for all three systems + +### Negative +- CLI complexity increases — more surface area to maintain +- Optional peer deps can confuse users (unclear what's installed) +- Node.js adapter for edge-net (browser-targeted WASM) may have compatibility gaps + +### Neutral +- Version coordination between `ruvector`, `pi-brain`, and `edge-net` requires semver discipline +- Existing `pi-brain` CLI (`npx pi-brain`) continues to work independently + +## 11.

A 64-character hex PI key in the path leaks the user's identity and authentication credential. + +**Fix**: Derive a SHAKE-256 pseudonym from the PI key and use that in the URL. The raw key is sent only in the `Authorization` header (which is not logged by standard infrastructure): + +```javascript +// AFTER (secure) +const pseudonym = require('crypto') + .createHash('shake256', { outputLength: 16 }) + .update(piKey) + .digest('hex'); +const resp = await fetch(`${EDGE_GENESIS}/balance/${pseudonym}`, { + headers: { 'Authorization': `Bearer ${piKey}` } +}); +``` + +**Files modified**: `bin/cli.js`, `bin/mcp-server.js` + +**Rationale**: SHAKE-256 is the same hash function used throughout the RVF wire format (ADR-058). The 16-byte (32-hex-char) pseudonym is sufficient for routing without revealing the key. The Authorization header is the standard HTTP mechanism for bearer tokens and is stripped by well-configured reverse proxies before logging. + +### 3.2 HIGH: SONA Status Native Binding Crash (NOTED) + +**Issue**: `npx ruvector sona status` crashes with `Module not found` when `@ruvector/sona` native bindings aren't installed. The SONA package has optional native acceleration via N-API that requires platform-specific compilation. + +**Status**: Not fixed in this release — the crash is in the `@ruvector/sona` package itself, not in the `ruvector` CLI. The CLI already lazy-loads SONA and catches import errors for the top-level module, but internal native binding failures propagate. + +**Mitigation**: Future `@ruvector/sona` release should wrap native binding calls in try-catch with WASM fallback. + +### 3.3 MEDIUM: Edge Genesis 404 Crash (FIXED) + +**Issue**: Edge network commands (`edge genesis`, `edge balance`) crashed when the backend returned non-JSON error responses (404, 502, etc.): + +``` +SyntaxError: Unexpected token 'N', "Not Found" is not valid JSON +``` + +The code called `resp.json()` without checking `resp.ok` first. + +**Fix**: Added response status check before JSON parsing in both CLI and MCP server: + +```javascript +if (!resp.ok) { + const errText = await resp.text().catch(() => resp.statusText); + console.error(chalk.red(`Edge network returned ${resp.status} ${resp.statusText}`)); + process.exit(1); +} +``` + +**Files modified**: `bin/cli.js`, `bin/mcp-server.js` + +### 3.4 MEDIUM: `hooks remember` Required `-t` Flag (FIXED) + +**Issue**: `npx ruvector hooks remember -v "some value"` failed with `error: required option '-t, --type <type>' not specified`. For a convenience command, requiring the type flag on every invocation is excessive UX friction. + +**Fix**: Changed from `requiredOption` to `option` with a default value of `'general'`: + +```javascript +// BEFORE +.requiredOption('-t, --type <type>', 'Memory type') +// AFTER +.option('-t, --type <type>', 'Memory type', 'general') +``` + +**Files modified**: `bin/cli.js` + +### 3.5 MEDIUM: `@ruvector/pi-brain` Not Installed (NOTED) + +**Issue**: Brain commands fail when `@ruvector/pi-brain` is not installed. It's declared as an optional `peerDependency` in `package.json`, but the error message isn't user-friendly. + +**Status**: Working as designed — pi-brain is an optional peer dependency. The lazy-load pattern already provides a clear error: `"Install @ruvector/pi-brain for brain commands"`. Users who want brain features install it separately. + +### 3.6 LOW: CLI Monolith Size (NOTED) + +**Issue**: `bin/cli.js` is 8,582 lines — a large single file. While it works correctly and loads fast (54.6ms), it makes maintenance harder. + +**Status**: Deferred. The file loads fast due to lazy-loading of heavy dependencies (GNN, attention, ora). Splitting would add complexity without performance benefit. If the file exceeds 10,000 lines, consider splitting by command group. + +### 3.7 LOW: `hooks recall` Non-Semantic Search (NOTED) + +**Issue**: `hooks recall --query` uses exact string matching (`includes()`) rather than semantic/fuzzy search. This limits discovery of related memories. + +**Status**: Deferred. Semantic search would require loading SONA embeddings for every recall, adding ~200ms latency. The current approach is fast and predictable. + +## 4.

Context + +The mcp-brain-server at pi.ruv.io is a production axum REST API on Cloud Run with 238+ shared memories, Phase 8 AGI subsystems (SONA, GWT, DeltaStream, DomainExpansionEngine), an RVF security stack, and a hybrid keyword+cosine+graph+reputation scoring pipeline. Current read latency is 60-80ms and write latency is 150ms at 40-concurrent p90=172ms. + +Despite this sophistication, several capability gaps remain: + +1. **No temporal pattern matching on embedding evolution**. The DeltaStream records embedding deltas over time, but there is no way to find memories whose embedding trajectories are *similar* to each other. Two knowledge nodes may evolve the same way (both drifting toward security topics, for instance) but the system cannot detect this. + +2. **No deadline-aware background task scheduling**. AGI subsystems (SONA tick, GWT decay, delta compaction) run ad-hoc inside request handlers or on status checks. There is no priority-based scheduler guaranteeing that critical maintenance (e.g., compaction before Firestore timeout) completes before less urgent work (e.g., pattern re-indexing). + +3. **No dynamical systems analysis of knowledge drift**. The DriftMonitor computes coefficient-of-variation but cannot classify whether the knowledge graph is converging to a stable attractor, oscillating in a limit cycle, or exhibiting chaotic drift. Lyapunov exponent analysis would provide this. + +4. **No formal invariant verification**. Memory operations have implicit invariants (witness chain integrity, embedding dimension consistency, quality score monotonicity under upvotes) that are checked procedurally. Linear Temporal Logic (LTL) verification would provide formal guarantees. + +5. **No recursive meta-cognition with safety bounds**. The DomainExpansionEngine does Thompson Sampling meta-learning but cannot recursively reason about its own learning strategy. Self-modification (changing exploration parameters based on accumulated regret) is manually tuned. + +6. **No high-performance brain-to-brain transport**. Federation currently uses HTTP/1.1 REST via reqwest.

Safety Considerations + +### 11.1 strange-loop Self-Modification Bounds + +The strange-loop crate's self-modification capability is the highest-risk component. The following safety envelope is enforced: + +**Hard limits (cannot be overridden)**: +- Maximum meta-depth: 3 levels (prevents infinite recursion) +- `always_safe()` constraint: no modification can produce a state where scoring coefficients sum to > 1.0 +- `eventually_terminates()` constraint: every `learn_at_level()` call must complete within 1000ms + +**Soft limits (can be tuned via env vars)**: +- `STRANGE_LOOP_MAX_DEPTH` (default: 3, range: 1-5) +- `STRANGE_LOOP_MODIFICATION_RATE` (default: 1 per 300s, range: 1 per 60s to 1 per 3600s) +- `STRANGE_LOOP_CURIOSITY_MIN` (default: 0.01) +- `STRANGE_LOOP_CURIOSITY_MAX` (default: 0.20) + +**Rollback mechanism**: If a self-modification causes any LTL property (Phase 9d) to fail in the next check cycle, the modification is automatically reverted and the strange-loop's modification capability is suspended for 1 hour (with WARN log). + +### 11.2 LTL Property Definitions + +The five core invariant properties are defined in Section 8 (Phase 9d). Additional properties can be added at runtime via the scheduler, but existing properties cannot be removed without a code change. + +**Verification semantics**: Properties are checked over the *trace buffer* (last 10K state transitions), not over all-time history. This bounds verification time and avoids false positives from pre-midstream state. + +### 11.3 Temporal Compare Privacy + +DTW trajectory matching could theoretically leak information about a contributor's knowledge evolution pattern. Mitigation: +- Trajectory buffers are category-scoped, not contributor-scoped +- Embeddings in trajectories have already been DP-noised (if `RVF_DP_ENABLED=true`) +- The `find_similar_generic` API returns distance scores only, not raw trajectories + +### 11.4 Scheduler Deadline Misses + +If the scheduler misses a deadline (e.g., under high load), the task is still executed but: +- `missed_deadlines` counter is incremented (visible in `/v1/scheduler/stats`) +- If `missed_deadlines > 10` in any 60s window, emit WARN log +- If `missed_deadlines > 50` in any 60s window, disable lowest-priority tasks (Background(10)) for 5 minutes + +## 12. Consequences + +### Positive + +- **Temporal pattern matching** enables discovery of memories with similar evolution trajectories, surfacing non-obvious relationships that cosine similarity alone misses +- **Deadline-aware scheduling** removes AGI maintenance work from the request hot path, reducing p99 read latency by ~5ms +- **Dynamical systems analysis** upgrades drift monitoring from simple CV thresholds to Lyapunov-exponent-based attractor classification, enabling early detection of chaotic knowledge domains +- **LTL verification** provides formal guarantees on system invariants, catching subtle bugs (dimension mismatches, witness chain gaps) that procedural checks might miss +- **Recursive meta-cognition** allows the brain server to self-tune exploration and scoring parameters based on accumulated evidence, reducing manual tuning burden +- **QUIC transport** (future) enables sub-millisecond brain-to-brain federation with 0-RTT resumption, a prerequisite for real-time multi-brain mesh +- **All features are independently feature-gated** with runtime env vars, zero risk to existing behavior when disabled +- **Total latency impact of +5ms on reads and +0.7ms on writes** stays well within the 100ms read budget + +### Negative + +- **Six additional crate dependencies** increase compile time by an estimated 30-45 seconds (quic-multistream alone adds ~20s due to quinn/rustls) +- **~8MB additional memory footprint** for in-memory trajectory buffers, analyzer state, and solver traces +- **Increased operational complexity**: six new env vars, six new endpoints, scheduler monitoring +- **strange-loop self-modification** introduces a novel failure mode: if safety constraints are misconfigured, the system could oscillate between parameter settings +- **LTL verification has false-positive risk** on edge cases where the trace buffer wraps around and loses historical context + +### Risks + +- **temporal-compare DTW** on high-dimensional (128-dim) sequences may be slower than expected if trajectory lengths grow beyond 100 steps; mitigation: cap max_sequence_length at 500 +- **nanosecond-scheduler** is designed for sub-microsecond scheduling, but tokio's cooperative scheduling has ~1ms granularity; actual scheduling precision will be millisecond-level, not nanosecond +- **temporal-attractor-studio** Lyapunov exponent estimation requires sufficient trajectory data (minimum ~30 points per category); new categories will show `insufficient_data` until populated +- **temporal-neural-solver** LTL verification confidence degrades if state transitions are sparse; the 30s check interval may verify the same state repeatedly during low-traffic periods +- **strange-loop** meta-learning effectiveness depends on diverse input signals; if traffic is dominated by a single category, meta-knowledge will be narrowly scoped +- **quic-multistream** requires TLS certificates for peer authentication; certificate management adds operational burden for multi-brain deployments +- **Crate version stability**: all midstream crates are at `0.1.x`; API changes in minor versions could require brain server updates + +## 13. Verification + +### 13.1 Compilation + +1. `cargo check -p mcp-brain-server` compiles with zero errors after adding all six dependencies +2. `cargo check -p mcp-brain-server --features quic-federation` compiles with quic-multistream enabled + +### 13.2 Existing Test Regression + +3. All Phase 1-8 tests continue to pass with all midstream flags disabled (default) +4. `/v1/status` returns all existing fields unchanged when midstream flags are off + +### 13.3 Feature Flag Isolation + +5. Enabling any single midstream flag does not affect behavior of other subsystems +6. Disabling a midstream flag mid-operation (via restart) gracefully drops in-memory state without errors + +### 13.4 New Endpoint Validation + +7. `GET /v1/temporal/trajectories?memory_id=<valid-uuid>` returns valid JSON with `similar_trajectories` array +8. `GET /v1/scheduler/stats` returns valid JSON with `total_scheduled >= 0` +9. `GET /v1/attractor` returns valid JSON with per-category `attractor_type` field +10. `GET /v1/invariants` returns valid JSON with `properties_defined >= 5` +11. `GET /v1/meta/strange-loop` returns valid JSON with `meta_depth <= 3` +12. `GET /v1/federation/stats` returns valid JSON with `status: "standby"` when no peers connected + +### 13.5 Scoring Pipeline Integrity + +13. With all midstream flags enabled, total midstream score contribution never exceeds 0.13 for any single memory +14. Search results with midstream enabled are a superset-reordering of results without midstream (no memories added or removed, only rank changes) + +### 13.6 Safety Constraints + +15. `strange-loop` with `max_meta_depth: 3` never recurses beyond level 3 (test with artificial depth-forcing input) +16. Self-modification that would set curiosity weight outside [0.01, 0.20] is rejected by safety constraint +17. LTL violation triggers WARN log but does not block the violating operation +18. Scheduler deadline miss increments counter without dropping the task + +### 13.7 Performance + +19. `search_memories` with all midstream flags enabled completes in < 100ms for 238 memories (p99) +20. `share_memory` with all midstream flags enabled completes in < 200ms (p99) +21. Background scheduler CPU usage stays under 1% of a single vCPU at steady state +22. Memory footprint with all midstream state initialized stays under 20MB total (existing + midstream) + +### 13.8 Load Test + +23. 40-concurrent search requests with all midstream flags enabled: p90 < 200ms, p99 < 300ms +24. No scheduler deadline misses under 40-concurrent sustained load for 60 seconds + +## 14. Migration Notes + +### 14.1 Backward Compatibility + +All existing API contracts are unchanged. New endpoints are additive. Midstream scoring signals are additive and bounded. No breaking changes to any existing client. + +### 14.2 Firestore Schema + +No Firestore schema changes required. All midstream state is in-memory only. Persistence of midstream state (attractor histories, LTL traces, meta-knowledge) is a future consideration for a follow-up ADR. + +### 14.3 Docker / Cloud Run + +The Dockerfile at `crates/mcp-brain-server/Dockerfile` needs no changes for Phases 9a-9e (pure Rust crates). Phase 9f (quic-multistream) requires exposing an additional UDP port in the Cloud Run service configuration: + +```yaml +# cloudbuild.yaml addition for Phase 9f only +ports: + - containerPort: 8080 # existing HTTP + - containerPort: 4433 # QUIC federation (UDP) + protocol: UDP +``` + +Note: Cloud Run currently has limited UDP support.
