fix(api-public): remove orphan import_export actors module

[NathanFlurry]

Summary

• main is currently broken on Rust CI and all engine Docker builds. Commit 34422ea93 ("chore: fix remaining issues with rivetkit-core") added engine/packages/api-public/src/actors/import_export.rs (874 lines, lifted from the unmerged 04-12-feat_import_export_actors branch) and wired it into mod.rs + router.rs, but the supporting pieces it depends on were never ported:
  • rivet-envoy-protocol and serde_bare deps in engine/packages/api-public/Cargo.toml
  • import_export / import_create modules in rivet-api-types::actors
  • actor_sqlite_v2 module in pegboard
  • pub visibility on list_inner
• Result: rivet-api-public fails with 15 compile errors (E0432 / E0433 / E0603), cargo build --bin rivet-engine exits 101, and every Docker -arm64 / -amd64 Build & Push job on branches off main fails. Example: https://github.com/rivet-dev/rivet/actions/runs/24889658855/job/72879003373.
• This PR removes the orphan file and its two wiring hunks. No other code references these symbols; the import/export feature can be re-added in a single self-contained PR that also brings the types, protocol, pegboard, and Cargo.toml pieces.

Test plan

• cargo check -p rivet-api-public passes
• cargo check --bin rivet-engine passes
• Wait for Rust CI + engine Docker builds to go green on this PR

Code Review

Overview

This is a targeted hotfix that removes an orphaned 874-line file (import_export.rs) and its two wiring hunks, unblocking a broken main. The root cause is clear: commit 34422ea93 cherry-picked import_export.rs from an unmerged branch without bringing along the required Cargo deps, API type modules, pegboard module, and visibility changes.

Assessment: Approve with one note

The change is correct, minimal, and the right call. Attempting to patch in the missing pieces in-place would be riskier than clean removal and re-introduction in a self-contained PR.

---

Observations

The Cargo.toml is already clean. rivet-api-public/Cargo.toml does not contain rivet-envoy-protocol or serde_bare, confirming those deps were never added — the orphan file referenced them but they were never wired up, exactly as described.

Lingering references in engine tests. The PR description states "no other code references these symbols," but two test files in engine/packages/engine/tests/ still reference the missing modules:

• actor_import_export_e2e.rs:13 — imports rivet_api_types::actors::import_export
• actor_import_export_e2e.rs:331,356 — calls pegboard::actor_sqlite_v2::import_actor / export_actor
• actor_v2_2_1_migration.rs:52 — calls pegboard::actor_sqlite_v2::sqlite_subspace()

Those test files live in dev-dependencies of rivet-engine and will still fail to compile under cargo test -p rivet-engine. They do not block cargo build --bin rivet-engine or the Docker image builds (the immediate goal here), but they should be addressed in a follow-up to keep the full test suite green.

Removed test coverage is acceptable here. The four unit tests inside the deleted file (selector_requires_exactly_one_variant, selector_accepts_actor_ids, kv_entry_round_trip, sqlite_entry_round_trip) are pure logic tests for the removed feature. Losing them temporarily is fine since the feature will be re-added in a complete PR.

The deleted code quality was solid. The batch pagination loop, rollback-on-failure path, deduplication logic, and serde_bare binary archive format were all reasonable. Worth preserving when the feature is re-introduced properly.

---

Suggestions for the follow-up import/export PR

• Bring actor_import_export_e2e.rs and actor_v2_2_1_migration.rs back in sync with (or gate behind) the feature addition.
• The selector_accepts_actor_ids test asserts ids.len() == 2 for two identical input IDs, but the dedup logic in parse_selector would reduce that to 1. Worth verifying the assertion matches the intended behavior before re-landing.
