Alignment Dialogue: RFC 0058 Supersession: Hybrid Relational + DynamoDB Architecture

Date: 2026-02-06 18:39Z Status: Converged ALIGNMENT Score: 415 (W:135 C:104 T:92 R:84) Rounds: 4 (R0-R3) Convergence: 100% (6/6 unanimous, Round 3) Tensions Resolved: 17/17 Linked RFC: 0058-encrypted-dynamodb-storage

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Domain: Data Architecture & Storage Strategy Question: Should RFC 0058 be superseded by a hybrid architecture that pairs a scalable relational database (PostgreSQL, CockroachDB, Neon, Turso) with DynamoDB, given that the RFC 0051 schema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"
