From b8b69736f7896169016d3315c12de9ba79240e04 Mon Sep 17 00:00:00 2001 From: OttoBot Date: Tue, 24 Feb 2026 06:48:19 -0600 Subject: [PATCH 1/3] docs: proto integration types spec for generated types verification MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Spec for Trello card 699621e4 — Integration Tests: Verify generated types with fiber engine. Key design decisions (from @research feasibility 2026-02-24): - Wire format boundary: DL1 JSON API stays Circe; proto binary for on-chain only - JsonLogicValue ↔ google.protobuf.Value: perfect compat via scalapb-circe - StateMachineDefinition → Struct: lossless encoding confirmed - fromProto must return Either[String, T] (UUID parsing, enum validation) 15 failing tests in 5 groups: - Group A: SMRecord binary round-trip (4 tests) - Group B: ScriptRecord binary round-trip (3 tests) - Group C: Cross-language TypeScript ↔ Scala (2 tests) - Group D: fromProto error handling (4 tests) - Group E: Pipeline integration with fiber engine (2 tests) Pre-condition: ProtoAdapters.scala must be implemented with all missing toProto fields (SMRecord: 5 fields; ScriptRecord: 5 fields) before tests can pass.

`StateMachineFiberRecord` proto ↔ hand-written round-trip +- `ScriptFiberRecord` proto ↔ hand-written round-trip +- `StateMachineDefinition` nested encoding +- `EventReceipt` and `ScriptInvocation` nested encoding +- Cross-language binary compatibility + +**Out of scope (separate card `699621e1d2651cedf586849f` — Migrate: Remove hand-written models module):** +- Removing `models/` module +- Migrating fiber engine to use generated types directly +- `OttochainMessage` fromProto (deferred — needs Phase 2 ProtoAdapters) +- Runtime-only types (`FiberGasConfig`, `ExecutionLimits`, `FiberContext`, `FiberInput`) — NO proto equivalents + +--- + +## 🧠 @think Perspective + +**Decomposition:** +This card validates ONE assumption at the heart of the proto migration: that the hand-written ↔ generated type boundary can be cleanly crossed without data loss. The natural split is: +1. Tests first (this spec) → 2. Implement ProtoAdapters → 3. Migrate engine to use generated types + +**Edge cases to watch:** +- `FiberOrdinal` is a refined `Long` (`Long Refined Positive`) — proto uses plain `FiberOrdinal` message (wrapping `value: uint64`). The refinement validation should be skipped in `fromProto` (trust the on-chain data). +- `Set[UUID] childFiberIds` → `repeated string child_fiber_ids`: order is not guaranteed. Tests must use `Set` comparison, not sequence equality. +- Empty `StateMachineDefinition` (no states, no transitions) is valid for scripts/delegations — test A1 should explicitly verify this edge case. +- `JsonLogicExpression` (for `scriptProgram`) is a recursive structure — deep nesting should round-trip via the same scalapb-circe bridge as `JsonLogicValue`. + +**Key risk:** If `JsonLogicExpression` Circe encoding doesn't match `google.protobuf.Value` proto3 JSON encoding exactly, the scriptProgram bridge will silently corrupt data. Test B1 must use a non-trivial expression (nested `if`/`var`) to catch this.
