From 11bf54a84db15604bc9987b95e5c4d58b0e07fbe Mon Sep 17 00:00:00 2001 From: fluffy314 Date: Sat, 11 Jul 2026 20:44:25 +0800 Subject: [PATCH 1/5] feat(distributed): add P2P prefill KV cache network Reuse compatible prefill snapshots across trusted nodes so expensive prompts can skip recomputation while decode remains local. Ship the gossip protocol, streaming KV data plane, dashboard, deployment assets, evidence, and release documentation together.

0016 — Distributed Prefill KV Cache Network + +- **Status:** Proposed / MVP implementation +- **Date:** 2026-07-11 +- **Relates to:** ADR 0008 (session runtime), ADR 0009 (capability gossip), + ADR 0013 (distributed topology), ADR 0015 (engine substrate) + +## Context + +Kakeya's bounded-memory runtime controls resident KV growth, but long prompt +prefill remains expensive. Multiple Mac minis often run compatible model +revisions and have idle unified memory that cannot become a coherent shared +address space over Thunderbolt. The useful resource is therefore not remote +RAM itself, but immutable prefill state that another node can import once. + +The initial rejected interpretation was a hot-path remote KV server queried +during every decoded token. That would add layer-by-layer network latency and +turn remote memory into distributed attention. This ADR instead keeps decode +local and places all network work before it. + +## Decision + +Kakeya nodes form a symmetric P2P fleet. Every node can be an inference head, +a prefill-cache requester, and a prefill-cache provider. The stored object is a +restorable prefill K/V snapshot; the reuse policy is chained longest-prefix +matching. + +Remote cache access happens only before decode: + +1. Tokenize the request and compute chained fixed-size block hashes. +2. Query the local cache and compatible live peers concurrently. +3. Select the longest contiguous prefix whose transfer/import cost is lower + than local prefill recomputation. +4. Transfer one immutable snapshot at the selected prefix boundary. +5. Import it, compute the missing suffix locally, then decode entirely locally. +6. Publish newly computed prefix-boundary snapshots asynchronously. + +There are no per-token remote reads and no coherent shared-memory illusion. + +The product name is **Distributed Prefill KV Cache**. “Prefill” names the +stored artifact; “prefix cache” names the chained longest-prefix lookup policy. + +## Three layers + +### Inference layer + +- `PrefixCacheStore` is an immutable, content-addressed, memory-bounded LRU. +- Each chained prefix hash maps to a complete restorable bounded-cache + checkpoint at that boundary. +- The MLX adapter serializes per-layer K/V, logical position, cached token + sequence, and next-token logits without pickle. +- `AppendTokensCoordinator` accepts an optional prefill-cache hook for cold + sessions. Cache failure is always a local-prefill fallback. + +### Network layer + +- Existing `CapabilityService` gossip remains the decentralized control plane. +- `NodeCapability` advertises interface-specific endpoints and exact cache + compatibility cards. +- `PrefillCacheService.LookupPrefix` is metadata-only. +- `PrefillCacheService.FetchBlocks` is a point-to-point streaming gRPC data + plane. +- Thunderbolt endpoints receive higher priority than LAN/Tailscale endpoints. +- Cards expire by TTL. Cache entries are immutable; reads require no + distributed lock. + +### UI and product layer + +The inference-network dashboard exposes: + +- node registration and expiring pairing tokens; +- online node inventory and coarse region distribution; +- cache discovery and pairing state; +- inference groups; +- completed and KV-assisted token totals; +- cache capacity, hit ratio, and transfer telemetry. + +Raw prompts, raw prefix hashes, exact IPs, and hardware serials are not public +UI data. + +## Compatibility tuple + +Remote K/V is accepted only when all fields match: + +- model id and exact weights revision; +- tokenizer/chat-template revision; +- quantization and K/V dtype; +- cache schema version; +- RoPE/position configuration; +- layer geometry; +- token block size. + +A mismatch is a cache miss, never a best-effort import. + +## Failure model + +- peer unavailable / lookup timeout → local prefill; +- stale card → TTL eviction; +- lease expired → local prefill or another lookup; +- incomplete stream / checksum mismatch → reject and local prefill; +- slow transfer → caller may cancel and recompute; +- node restart → cache epoch changes; stale leases are invalid. + +Remote cache availability must never determine request correctness. + +## Security + +The MVP assumes a trusted private fleet. Production pairing must bind `node_id` +to mTLS credentials or a fleet PSK. Prompt-derived block hashes should be HMACed +when membership attacks are in scope. + +## Observability + +Every node reports: + +- capability-card freshness and endpoint RTT; +- cache bytes used/free, entry count and epoch; +- local/remote lookup hit/miss counts; +- snapshot publish/fetch bytes and checksum failures; +- completed inference tokens and KV-assisted prompt tokens; +- fallback reason and local recompute count. + +The public dashboard shows aggregate/coarse data. Exact addresses, prompt +hashes and payload metadata remain administrator-only. + +## Consequences + +Positive: + +- expensive prompt prefill is reused across processes, restarts and nodes; +- the remote peer's memory becomes a useful cache tier without changing decode; +- node failure cannot change output correctness; +- the existing capability gossip and tensor codec remain the shared substrate; +- cache-only peers need no loaded model when they receive replicated snapshots. + +Costs: + +- snapshots are large and must be chunked; +- each model/tokenizer/cache revision creates a separate namespace; +- cache snapshots duplicate state at block boundaries in the MVP; +- peer memory is volatile and cold after restart; +- trusted-LAN deployment precedes production identity/auth hardening. + +## Alternatives considered + +### Per-token remote KV reads + +Rejected. Attention would require remote communication in every transformer +layer, adding latency to the autoregressive critical path. + +### Coherent shared memory over Thunderbolt + +Rejected. Thunderbolt Bridge exposes IP networking, not a cache-coherent +CPU/GPU address space or GPU-direct remote memory. + +### Exact full-prompt cache only + +Rejected as the sole policy. It is simpler but misses common-system-prompt and +shared-prefix reuse. Chained block hashes preserve causal correctness while +allowing suffix-only prefill. + +### Arbitrary block/hole reuse + +Rejected. Later K/V depends on the complete preceding token sequence and +positions. Only the longest contiguous prefix is safe. + +### SMB/NFS snapshot files + +Rejected for the serving data plane. Files remain useful for offline +checkpoints, but gRPC provides explicit framing, checksums, leases, +backpressure and cancellation. + +### Central registry + +Rejected. Existing symmetric CapabilityService gossip already provides +eventually-consistent discovery and TTL expiry without a new coordinator. + +## Rollout + +1. Enable cache services on a private two-Mac Thunderbolt fleet. +2. Run shadow lookup/publish while still computing prefill locally. +3. Compare imported continuation logits against local prefill. +4. Enable remote import with mandatory compatibility/checksum validation. +5. Add launchd supervision, token telemetry and public read-only dashboard. +6. Require mTLS/PSK before expanding beyond trusted private nodes. + +The cache feature is disabled by omitting `--enable-prefill-cache`. + +## Rollback + +Stop cache/dashboard launchd services and restart RuntimeService without the +cache flag.
