End users get ONLY Zeta as production substrate. Distributed-maintainer-architecture pattern. Skills around these DBs compose.

+# Distributed maintainer architecture — local DB/bus toolkit for maintainers, Zeta for end users (Aaron 2026-05-13)
+
+**Why:** Aaron 2026-05-13: *"damn this could be useful
+https://fslab.org/RProvider/ also feel free to use sql server
+dockeer image for anythng you need the devloper license is
+free and we can allow any maintiners to use it for free to so
+any skills around it would compose same with postgres sql and
+really any database or bus system locally, i'ts like distribued
+maintainer archiceture, you can't count on end users to have
+it they will have zeta but can all be prototyped in exiting db
+and find strengths and weakness and sql server locally has r
+and pythong and java build into stored procedures we will have
+dotnet"*. Canonical architecture-tier substrate.
+
+**How to apply:** When prototyping factory features or
+investigating strengths/weaknesses of design choices:
+
+1. **Maintainers can use ANY local DB/bus system** — SQL Server
+   Docker (dev license free), Postgres, any DB, any bus
+2. **Skills around these compose** — factory skill catalog can
+   include DB/bus-specific skills since maintainers have access
+3. **End users get ONLY Zeta** — production substrate
+4. **Existing DBs are PROTOTYPING substrate** — find strengths +
+   weaknesses; Zeta inherits the strengths
+5. **SQL Server stored procedures** support R + Python + Java
+   built-in; Zeta will have dotnet (F#/C#)
+6. **R Provider for F#** named as useful F# type provider
+   (fslab.org/RProvider/) — composes with B-0428 DBpedia
+   substrate

+
+## Decomposition
+
+### 1. Distributed maintainer architecture
+
+**Pattern**: maintainers have local rich toolkit; end users
+have minimal toolkit.
+
+| Audience | Tools available | Why |
+|---|---|---|
+| **Maintainers** | SQL Server (Docker, dev-license-free) + Postgres + any DB + any bus system locally + R + Python + Java + dotnet | Prototyping + strength/weakness discovery |
+| **End users** | Zeta only | Single deployment substrate |
+
+This composes with:
+- PR #2924 (Aurora pitch — edge node runs models/policy + small
+  BTC node/miner; end-user edge nodes are minimal)
+- B-0424 (Stage 1 factory split — distribution shape)
+- B-0425 (product-repo split — Zeta vs prototyping infrastructure)
+
+### 2. SQL Server Docker (dev-license-free)
+
+- Microsoft SQL Server Developer Edition: free for development
+- Docker image: official `mcr.microsoft.com/mssql/server`
+- Permitted for any maintainer to use locally per Aaron's
+  authorization 2026-05-13
+- Stored procedures support: T-SQL + CLR + **R + Python + Java**
+  (built-in to SQL Server Machine Learning Services)
+- Substrate composition: maintainers can prototype substrate
+  features using R/Python/Java + SQL Server before porting to
+  Zeta's dotnet substrate
+
+### 3. Postgres + any DB + bus systems
+
+Aaron's permission: maintainers can use ANY local DB or bus:
+- Postgres + pgvector (vector DB)
+- Redis (cache + pub/sub)
+- RabbitMQ, NATS, Kafka (message buses)
+- DuckDB (analytical)
+- SQLite (embedded)
+- ClickHouse (columnar)
+- Any other locally-runnable substrate
+
+Skills around these compose with the factory's skill catalog —
+maintainers can author skills targeting any of these systems
+because the toolkit is available.
+
+### 4. Prototyping → Strength/Weakness discovery → Zeta inherits strengths
+
+Operational flow:
+
+1. **Prototype** in existing DB/bus system
+2. **Find strengths**: what works well; why it works
+3. **Find weaknesses**: what breaks; why; what trade-offs apply
+4. **Port strengths to Zeta**: Zeta inherits the strength
+   patterns; weaknesses get designed-around in Zeta
+
+This is canonical substrate-engineering R&D pattern — don't
+invent from scratch; learn from existing systems; build the
+strengths into Zeta.
+
+### 5. R Provider (fslab.org/RProvider/) — F# type provider for R
+
+- Aaron-named as "could be useful" 2026-05-13
+- F# type provider for R statistical computing
+- Composes with B-0428 (DBpedia F# CE Path B); B-0428 deferred
+  Path A type-provider-on-FSharp.TypeProviders.SDK substrate
+- R has rich statistical + ML ecosystem
+- Maintainers can use R + F# together via this type provider
+- Composes with SQL Server R support (above) — same R libraries
+  accessible from F# OR from SQL Server stored procedures
+
+### 6. SQL Server vs Zeta stored procedures
+
+| System | Languages in stored procedures |
+|---|---|
+| **SQL Server** | T-SQL + CLR + **R + Python + Java** (Machine Learning Services) |
+| **Zeta (future)** | dotnet (F# + C#) — composes with F# computation expressions |
+
+The stored-procedure pattern lets DB-resident compute access
+data without network roundtrips. Zeta's dotnet stored procedure
+will compose with:
+- F# computation expressions (PR #2929 storage substrate)
+- Z-set / Clifford / BP/EP algebra (algebra-owner skill)
+- DBSP retraction-native semantics
+- HKT-MDM (PR #2913)
+- Real-HKT-over-Clifford after F#-compiler-fork-for-AI-safety
+  (PR #2928 deferred Path A substrate)
+
+## Composes with
+
+- PR #2929 (storage layer no-binary requirement — distributed
+  maintainer can use rich local storage; Zeta storage is the
+  end-user substrate)
+- PR #2928 (DBpedia + F#-fork substrate — RProvider composes
+  with type-provider tooling)
+- PR #2924 (Aurora pitch — edge-node minimal; maintainer
+  toolkit rich)
+- PR #2913 (HKT-MDM universality — DB choice affects MDM
+  ontology binding)
+- PR #2917 (vision monad Play-Doh — soft + reshapeable;
+  prototyping substrate)
+- PR #2892 (KSK — typed-safety motivation for Zeta dotnet)
+- B-0424 (Stage 1 factory split — distribution shape; what
+  goes in factory vs Zeta)
+- B-0425 (product-repo split — Zeta lives in its own product
+  repo)
+- B-0428 (DBpedia F# CE — RProvider type-provider composes
+  with deferred Path A)
+- B-0043 (universal company + government information substrate
+  — master-data storage)
+- `.claude/rules/fsharp-anchor-dotnet-build-sanity-check.md`
+- `.claude/rules/dv2-data-split-discipline-activated.md`
+- `.claude/rules/glass-halo-bidirectional.md`
+- `.claude/rules/no-directives.md` (maintainer choice of local
+  DB/bus is autonomous)
+- algebra-owner skill (Z-set + Clifford + BP/EP F# substrate)
+- DBSP substrate (event-sourcing + retraction-native algebra)
+
+## Operational implications
+
+### For maintainer onboarding
+
+Onboarding doc should include:
+- Permission for SQL Server Docker dev-license-free use
+- Permission for any local DB/bus system
+- Skills around DB/bus that compose with factory
+- Distinction: prototyping in local DB ≠ production Zeta
+
+### For factory skill catalog
+
+Skills targeting specific DBs/buses are allowed + welcomed:
+- `sql-server-prototyper` skill
+- `postgres-vector-pgvector` skill
+- `rabbitmq-bus-explorer` skill
+- `r-statistical-via-rprovider` skill (composes with B-0428
+  deferred Path A)
+- Any other DB/bus prototyping skill
+
+### For Zeta product positioning
+
+Zeta IS the end-user substrate. Maintainer-only tools (SQL
+Server, Postgres, R, etc.) are NOT distributed with Zeta —
+they're maintainer infrastructure.
+
+Composes with:
+- PR #2917 vision monad Play-Doh (bounded scope) — Zeta is
+  bounded; toolkit-around-Zeta is unbounded
+- Aaron's "you can't count on end users to have it" — substrate-
+  honest framing
+
+### For B-0428 DBpedia Path B implementation
+
+Path B (direct dotNetRDF + F# CE) prototyping can leverage:
+- SQL Server local instance for caching DBpedia results
+- Postgres for graph-database experiments
+- RProvider for statistical analysis of DBpedia entity-attribute
+  distributions
+- All composed with F# CE substrate
+
+### For Aurora pitch deployment
+
+Aurora's "edge node runs models/policy" implies end-user
+deployment is Zeta. Maintainer prototyping can use richer
+local toolkit. Aurora partnership pitches can describe Zeta as
+the deliverable + maintainer-toolkit as the R&D process.
+
+## Substrate-honest framing
+
+The distributed-maintainer-architecture pattern is substrate-
+honest:
+
+- Maintainers HAVE rich toolkit (not pretending to limit
+  themselves)
+- End users HAVE minimal Zeta (not pretending to deliver
+  rich-toolkit)
+- The asymmetry IS substrate-engineering reality — maintainer
+  productivity multiplied by toolkit access; end-user
+  simplicity multiplied by minimal deployment
+- Substrate-honest pattern: don't pretend asymmetry doesn't
+  exist; design WITH it

+
+## Operational rule for future-Otto
+
+When prototyping factory features:
+
+1. **Use any local DB/bus** maintainer has — toolkit is open
+2. **Author skills** around the tools — they compose with
+   factory skill catalog
+3. **Find strengths + weaknesses** through prototyping
+4. **Port strengths to Zeta** — Zeta inherits R&D insights
+5. **Don't ship local-toolkit to end users** — Zeta is the
+   delivery substrate
