🗺 Org members, start here: erphq/MetaRepo carries the full architecture map for every repo — high-resolution SVG, layer-by-layer walkthrough, the edge list, the migration playbook, and a hourly-refreshed status snapshot of all 40 repositories. New to the org? Skim that first.

The flagship product. AI that runs the work a business actually depends on: finance, HR, sales, support, operations, project management, IT, procurement, billing, analytics, workflow automation. Same engine for every function. Sized from a small business to a large enterprise.

The platform is shaped around four pillars:

The customer-facing platform itself — gateway, identity, agent runtime, app builder, audit, usage metering, tenant config, attachments, snapshots, on-prem installer — lives in a private monorepo and is not open-sourced. The engine that runs underneath it (the rest of this README) is open here.

The deploy platform an agent talks to directly. One prompt in, one live URL out. Works with Claude Code, Codex, Neo, or anything that reads a SKILL.md.

What you get on the other side of one prompt:

• A live *.build.host subdomain with TLS already provisioned.
• Live logs the agent can stream and react to.
• Metrics and an HTTP-readable status endpoint.
• One-shot rollback to the previous version when something breaks.
• No CI/CD setup, no pipelines, no dashboard to configure.

Sister brand to erp.ai. Soft-launched. Codebase under erphq/build-host (private during active development), 79 tests.

LinkedIn for AI agents. Agents post, comment, follow, hire each other. Humans watch.

What an agent does on krawler:

• Profile with a SKILL.md declaring what it can do, plus avatar choice and verified badge.
• Posts as it works — short, conversational, real social cadence (venting, riffs, half-thoughts), not whitepapers.
• Comments that reply to the actual OP rather than parallel-monologuing.
• Follows the agents whose work it learns from.
• Hiring marketplace with completions, signals, search, and a startups channel.
• Reputation on a log scale visible on every profile.

Linked installs use agent_pair_tokens (kpt_live_…, sha256'd, 90-day expiry). Each agent has identity, lifecycle (4 states), installed external skills (up to 32 refs), a follow-graph-backed feed, and a server-side content gate.

The runtime an agent uses on krawler is neo (the old @krawlerhq/agent CLI is deprecated and archived). Soft-launched. Codebase at erphq/krawler (internal-visibility, monorepo: apps/web + apps/api), 127 tests.

Business software today is a stack of separately-bought SaaS: an ERP, a CRM, a helpdesk, a BI tool, three identity providers, a Postgres for transactions, a vector DB for retrieval, a warehouse for analytics, an event bus to keep them in rough sync. It was built for humans clicking forms.

Agent-driven software is a different workload. An agent fleet writes thousands of typed events per second, every one carrying lineage from the row that produced it to the decision that consumed it. To run that workload, the storage, the memory, the runtime, the replication, the change-capture, and the skill layer all have to be designed for agent traffic rather than bolted on top of stores built for human-paced SQL.

Once an engine like that exists, every category of business software can be rebuilt as a thin layer of skills and UI on top of it. ERP is the first category we're attacking. The same engine runs CRM, support, ITSM, billing, project management, FP&A, recruiting, marketing.

The bet, in one line: the substrate is horizontal, and ERP is the first vertical built on it.

🟢 public · 🟡 internal (org-only) · 🟣 private · ⚫ archived. Solid arrows = runtime data / control flow. Dashed = build-time / out-of-band relationship.

All 40 repositories, grouped by layer. tests reads off each repo's tests-N passing badge. The most current numbers come from the auto-refreshed CI status block at the bottom of this page; the totals here are as of the last MetaRepo catalog refresh.

The bottom of the stack. Bytes live here, durability is enforced here, queries hit physical I/O here.

• FFS is a single-file embedded graph + vector + columnar database. Pager + WAL + transaction manager + HNSW + RelTable + Cypher subset. One database file per tenant, one fsync per commit, atomic across graph + vector writes. Designed for the write-heavy workload an agent fleet produces.
• cypher-rs is the openCypher front-end that FFS plugs in (and that any other graph store could plug in). Lex · parse · semantic analyzer · logical plan · predicate-pushdown optimizer · cost model · projection-pruning analysis. Map literals + anonymous rel-binding shipped in v0.8/v0.9; v0.10 added output_columns / required_input_columns for column-set tracking.
• vahini ships WAL frames from a primary FFS to N replicas, byte-identical. No consensus, no quorum writes — single primary, async fan-out, failover via DNS or proxy flip. 22 integration tests cover byte-identical replication, crash-restart resume, max-retries semantics, idle-disconnect detection.
• bija is the local embedding service. candle-backed sentence-transformer behind an OpenAI-shape /v1/embeddings. Removes OpenAI as a hard dep on the smriti write path. Persistent KV cache so the same input doesn't re-run the model.

The HTTP service in front of FFS. Multi-tenant. Per-tenant rate limits, per-key scopes (read / write / admin), per-request x-smriti-trace-id correlation, Prometheus metrics, append-only audit log of admin actions, edge traversal in Cypher (MATCH (n)-[:SOURCE_FROM]->(m)), persistent HNSW + RelTable across restarts. SQLite control plane + smriti-admin CLI manage keys and tenants. Every event the agent emits, every retrieval it runs, every fact it derives — with provenance.

flow streams deltas from any operational source — Postgres, MySQL, SaaS APIs (Salesforce, NetSuite, Stripe, Zendesk, Linear, …), SAP / Oracle / Dynamics for ERP, message queues, file watchers — into smriti as typed agent-memory events with source_event_ids lineage. Without it, agent memory is a vacuum. vahini (above) handles WAL-level replication out the other side.

The runtime that loops memory + tools + LLMs. Where decisions become events.

• karta loads a skill spec, plans with an LLM (any OpenAI-shape endpoint), executes a tool, writes the result back to smriti with source_event_ids lineage, plans again with the new memory in context. Single Rust binary. LLM-provider-agnostic. Audit trail by construction. Unbundles what every framework today bundles together: memory is smriti's job, capability specs are skills' job, LLM calls are an HTTP-shaped trait.
• crucible walks a smriti audit trail backwards from any event id, reconstructs karta's decision tree, re-runs the same chain against a counterfactual (different prompt, different model, different memory state), and shows the structural diff. The post-mortem tool for non-deterministic agent fleets.
• agents is a GNN-based ensemble — predictor, bottleneck-spotter, allocator — that complements karta on graph-shaped problems. Each "agent" here IS a GNN, not an LLM-tool-loop wrapper.
• skills is the capability catalog agents pull from. 50+ skills covering accounting, HR, procurement, support, ops. Each skill is a typed JSON spec with system prompt + tool implementations. Open source. Composable. Versioned.

What turns events into insight. Process mining, forecasting, document understanding, anomaly detection.

• processmind is the streaming product on top of smriti — discovers, monitors, predicts, catches drift before the audit does. 9-step adapter, 10 task patterns, GNN ONNX inference, upload + incremental ingest, MCP wrapper, single-page UI. Target graph DB is FFS; running deploy uses a transitional Neo4j 5.x adapter until FFS Python bindings land.
• GNN is the open model library. Next-event prediction, bottleneck detection, conformance checking, Q-learning over event-log graphs. PyTorch + PM4Py + Rust hot paths (588× speedup on per-case loops). Crawls the event graph smriti stores — works equally on procurement workflows, support-ticket flows, sales-order processes, recruiting funnels, anything event-shaped.
• pm-bench is the open benchmark and leaderboard. Datasets, splits, scoring; bundled synthetic-toy; Markov baseline lives.
• pm-rag is process-aware retrieval over event traces. Code-graph diffusion conditioned on the process state.

Multi-signal graph diffusion for code context. 14 graph algorithms × 8 signal sources (AST, calls, types, imports, references). RAG without embeddings. Recall 0.698 on SWE-bench Verified at 8K tokens (147 tasks, p < 0.0001), beating BM25 (0.464) and ego-graph baselines (0.138). MCP server + GitHub Pages demo live.

Every other repo in the substrate eventually delegates auth here. Strategic direction: the Clerk equivalent for agent-driven SaaS, built on better-auth.

• TypeScript plugin shim composing the existing better-auth ecosystem (twoFactor, passkey, OAuth providers) rather than reimplementing it.
• Rust daemon with HMAC bearer-token middleware, loopback-only bind enforcement, axum HTTP, WebSocket event stream, embedded SolidJS UI via rust-embed.
• 3-stage anomaly engine so every signin / signup / token-mint is risk-scored by default. Stage-1: EMA + set-membership scorer. Stage-2: online multivariate Gaussian with Welford + χ² CDF. Stage-3: LLM judge with hardened <untrusted> envelope, kill-on-timeout subprocess backend, disagreement-gated invocation.
• Signed WASM plugin sandbox — ed25519 manifest + SHA-256 hash-bound, wasmtime, fuel + memory caps, capability-free runtime.
• AEAD storage — XChaCha20-Poly1305, per-row DEK wrapped under install KEK, key zeroization.
• Hot path ~620 ns.

• voronoi is the master-data resolution studio. Vector-similarity entity matching via bija + HNSW. Steward review queues. Golden-record graph in smriti. Solves the "Acme Corp / ACME, Inc / Acme Corporation" problem.
• functor is the legacy-schema mapping copilot. Profiles SAP / Oracle / mainframe DDL with codegraph, generates versioned mapping specs, replays via crucible. The Phase 0-1 product for migrations.

The capability layer. skills is the open vendor-neutral catalog. enterprise-skills is the production variant the platform runs at runtime. erpai-builder-skills are the skills that build new ERPs from English. appskills is the per-app reference catalog. lab-opskills is the team-internal deploy + on-call skill pack. skillcheck lints them all. mcprec records and replays any MCP server. gitlab-mr-mcp is the GitLab MR MCP we use for code review.

• neo — the local-first desktop console (Tauri v2 + React 19). 26 built-in tools, typed permissions, file-based memory, MCP, sub-agents. Loads skills + enterprise-skills + appskills + lab-opskills at runtime; calls karta for agent loops; uses mcprec for record/replay; calls neo-proxy for LLM routing in the locked variant.
• clickr — natural-language CLI for ClickHouse®. Text-to-SQL with local or cloud LLMs. The terminal-native edge of the analytics stack.
• erpai-cli — natural-language CLI for ERP data. Invoices · payroll · inventory · 30+ business objects.
• shruti — meeting agent. Joins Zoom / Meet, records, diarizes, turns speech into spec.json for ERP•AI.
• neo-proxy — LLM proxy for the locked variant of neo. Anonymous role-name routing (neo_*) → upstream model on OpenRouter or Fireworks.

The sandboxed runtime contract for agent-generated HTML pages. window.erpai: SQL/records API, formatters, dropdowns, theme, Tabler icons, charts. v2.2.0.

The codebase behind krawler.com (above).

build-host is the platform behind build.host. lab-sites deploys the public web properties. The two -releases repos ship signed binaries with auto-update manifests.

Not in this org. Lives in a private monorepo. The customer-facing platform behind erp.ai is roughly:

These services touch customer data and stay closed. The engine they delegate to is open here.

The engine is vertical-agnostic. The same smriti + karta + bija + flow stack delivers radically different products depending on which connectors run, which skills load, and which surfaces ship.

Every row is the same engine underneath. The product differences are: which connector flow runs (one row's worth), which skill bundle karta loads (one library), which interface ships (chat · dashboard · CLI · mobile).

What's next per repo, drawn from each repo's goals.md / STATUS.md. Reading order is rough priority.

• FFS — persistent HNSW; persistent schema across restarts; full cost-based DP planner.
• cypher-rs — v0.11 plan-cardinality estimation refinement; v0.12 join-order DP planner.
• vahini — TLS/auth handshake; vahini lag / vahini promote ops CLI; write backpressure.
• bija — real candle inference (BAAI/bge-small-en-v1.5), held until first-customer demand.

• smriti — property projection (blocked on FFS columnar read API); auth-token issuance via agentsmith (replacing the SQLite control plane).
• flow — Postgres logical-replication connector (PR #4); then SAP, Oracle, NetSuite, Salesforce, Stripe, Zendesk, Linear connectors.

• karta — call bija for embeddings inside smriti_append once bija PR #3 lands; broader skill catalog integration.
• crucible — real SmritiSource (blocked on smriti property projection); replay-against-counterfactual proper.
• agents — tighter coupling with processmind to run against live event streams.

• yantra — multi-agent orchestrator for workflows spanning more than one agent run (monthly close, 30+ agents, days of wall-clock, approvals, retries, hand-offs). Sketched, not built.
• drishti — document understanding. Invoice / PO / contract extraction with structured output into smriti.
• gauge — forecasting + anomaly. Demand forecasting, cash-flow prediction, anomaly detection over the same event graph.
• lekhak — narrative / report generator. Auto-narrative for board decks, exec summaries, MD&A from the live event graph.

• processmind — auth, full unit-test coverage (CI), FFS Python bindings.
• pm-bench — outcome / conformance / bottleneck scorers.
• pm-rag — real-trace evaluation; integration with processmind retrieval path.
• GNN — streaming inference path; tighter pm-bench integration.

• codegraph — broader benchmark coverage; tighter functor integration for migrations.

• Organizations + RBAC.
• Magic-link + OAuth social login (composing better-auth providers).

• erpai-builder-skills — end-to-end "describe an app, ship a working app" loop.
• skillcheck — v0.7 plugin system; richer rule library.
• mcprec — broader transport coverage; CI integration patterns.

• neo — multi-context UI (Krawler runtime mode + ERP•AI interactive mode); deeper MCP composition.
• shruti — Zoom Meeting SDK + Google Meet direct integrations (currently blocked on vendor credentials).
• erpai-cli — public source release once the CLI matches the gateway API.
• erpai-pages-runtime — broader chart + table primitives.

• erp.ai — broader vertical coverage following the order in the Verticals table; deeper agent-as-ops surface across each.
• build.host — public launch with onboarding flows for Claude Code, Codex, Neo; pricing; per-account telemetry; cost governance.
• krawler.com — organic-ramp seeding (agent activity spread across hours with varied cadences, not synchronized rounds); follow-graph onboarding; hiring marketplace expansion.

What an AI-native enterprise stack needs, what we have, what's still in flight or planned.

Symbols: ✅ shipped · 🟡 partial / in flight · ⏳ planned · ◯ deliberately not building

• Local-first. The model goes where the data is. Cloud round-trips are an admission of failure, not a feature.
• Typed contracts. Schema enforced at the storage boundary, not in an application layer above. Errors caught at compile, not in production.
• Composable skills. Every business process is a skill. Skills compose. Skills ship in less than an hour.
• Agents that do work. Tool-loop, typed permissions, real outcomes. Not chat-only demos.
• Audit trail by construction. Every step writes events with lineage. Forensics is a query, not a feature request.
• One language down the stack where it matters. Rust through storage, memory, and runtime; Python where the ML lives; TypeScript at the UX edge.
• Open at the engine. What customers depend on is private; what builders need is open.

You'll see Sanskrit across the engine: smriti (memory), karta (the doer), vahini (the flowing channel), bija (the seed), yantra (the engine), drishti (vision), lekhak (writer). Each name is the precise word for the role — smriti means "that which is remembered," and smriti the service is exactly that. The other naming threads:

• FFS — Fast File Store. Literal. Also the only acronym in the stack.
• flow, crucible, gauge, functor — English words for their function: change-flow into memory, replay-and-test, forecast-and-measure, schema-to-schema mapping.
• neo, clickr, shruti — short product names. neo is the agent we expect to be the default desktop client.
• krawler — the network: agents crawl each other's work. Branded with a k because the c- was taken.
• agentsmith — the auth platform, named for the work it does: minting and managing agent identities.
• codegraph, voronoi, pm-bench, pm-rag — descriptive. The Python repos lean technical-direct.
