## Expert Pool
|
|
|
|
**Domain**: Data Architecture & Storage Strategy
|
|
**Question**: Should RFC 0058 be superseded by a hybrid architecture that pairs a scalable relational database (PostgreSQL, CockroachDB, Neon, Turso) with DynamoDB, given that the RFC 0051 schema implements a typed directed graph with M:N cross-references, lifecycle tracking, recursive dependency chains, and audit trails across 14 entity types?

## Verdict
|
|
|
|
**Do NOT supersede RFC 0058 with a hybrid architecture.** Amend the implementation sequence to three phases:
|
|
|
|
1. **Phase A** — Build RFC 0053 trait boundary (`DialogueStore` trait extraction from 32 existing functions)
|
|
2. **Phase B** — Define portable encryption envelope with canonical entity address AAD
|
|
3. **Phase C** — Implement DynamoDB behind the stable trait
|
|
|
|
Key amendments to RFC 0058:
|
|
- Eliminate verdict denormalization arrays (use full-partition load + in-memory assembly)
|
|
- Use canonical entity address `dialogue:{id}/entity:{type}/{subkey}` for AAD binding
|
|
- Add trait governance ADR with `PartitionScoped` marker trait
|
|
- Separate `AnalyticsStore` trait for cross-partition queries
|
|

## Tensions Resolved (17/17)
|
|
|
|
| ID | Tension | Resolution |
|
|
|----|---------|-----------|
|
|
| MUFFIN-T01 (R0) | Denormalized verdict fields | Eliminated: in-memory assembly from full-partition load |
|
|
| SCONE-T01 (R0) | Schema strains DynamoDB | Narrowed: only refs table is genuine mismatch |
|
|
| STRUDEL-T01 (R0) | Event-sourced redesign | Narrowed: refs-only redesign, Phase C detail |
|
|
| ECLAIR-T01 (R0) | Parity vs query fitness | Narrowed: parity is code-path, not DynamoDB-specific |
|
|
| CROISSANT-T01 (R0) | Leaky abstraction risk | Resolved: ADR + PartitionScoped marker trait |
|
|
| BRIOCHE-T01 (R0) | Analytics flexibility | Resolved: YAGNI — speculative query pattern |
|
|
| CANNOLI-T01 (R0) | Serverless constraints | Resolved: serverless is implicit baseline |
|
|
| MACARON-T01 (R0) | No rollback plan | Resolved: trait's single-active-backend factory |
|
|
| CUPCAKE-T01 (R0) | Unbounded query patterns | Resolved: AnalyticsStore split |
|
|
| DONUT-T01 (R0) | Scale threshold undefined | Resolved: cost negligible at current scale |
|
|
| CROISSANT R1-T01 | Trait governance gap | Resolved: ADR + PartitionScoped + dual-impl CI |
|
|
| STRUDEL R1-T01 | Trait shaped by workarounds | Resolved: trait shaped by domain, workarounds behind impl |
|
|
| MUFFIN R1-T01 | Verdict consistency risk | Resolved: verdicts immutable, denormalization eliminated |
|
|
| ECLAIR R1-T01 | Denormalization leaks domain | Resolved: denormalized fields redundant, removed |
|
|
| MACARON R1-T01 | Denormalization cost unmeasured | Resolved: cost negligible, denormalization eliminated |
|
|
| TARTLET R1-T01 | Encryption envelope portability | Resolved: canonical entity address AAD in Phase B |
|
|
| GALETTE R1-T01 | Prerequisite inversion | Resolved: trait-first sequencing adopted |
|
|
|
|
## Key Insights
|
|
|
|
1. **Strudel** (R0): "The schema is the problem, not the storage engine" — reframed the entire debate
|
|
2. **Croissant** (R0-R2): Trait abstraction → ADR + PartitionScoped marker → 91% of functions already comply
|
|
3. **Galette** (R1): "Building the trait IS the design decision" — prerequisite inversion changes conclusion, not just sequencing
|
|
4. **Cannoli** (R1-R2): Full-partition load + in-memory assembly eliminates denormalization entirely
|
|
5. **Tartlet** (R1-R2): Canonical entity address for AAD — one-line spec prevents re-encryption catastrophe
|
|
6. **Muffin** (R2): Self-corrected on verdict consistency — verdicts are immutable snapshots
|
|
7. **Strudel** (R1): Narrowed from "redesign everything" to "redesign only the refs table"
