Part of master roadmap #1.

Migrate 15 Actix-Web controllers (189 REST endpoints) to Axum route handlers backed by OsisMarketplace domain.

Scope

Rewrite 15 controllers from Actix to Axum
Migrate Tera template rendering to Axum
Migrate JWT auth + cookie session middleware
Replace ServiceProvider DI with OsisMarketplace domain
Update static/js/base.js API calls
Remove Actix dependency

Acceptance criteria

All 189 endpoints served by Axum
All 65 Tera templates render correctly
JWT auth works
Smoke tests pass
Actix dependency removed from Cargo.toml

Why Actix → Axum

1. AxumRpcServer is the Hero runtime

hero_rpc_osis::rpc::AxumRpcServer — the JSON-RPC 2.0 dispatch layer produced by the code generator — is built on Axum. The freezone backend uses it. Every Hero service uses it. The generated OsisMarketplace domain plugs directly into it. Running Actix alongside would mean two web frameworks in one binary for no reason.

2. One framework, not two

With the RPC server (P1c) we already added Axum as a dependency. Keeping Actix means two async runtimes, two middleware stacks, two sets of extractors, double the dependency tree, and developers needing to know both.

3. Generated code expects Axum

osis_server_generated.rs produces Axum router builders. The service handlers use Axum State pattern. build_router() returns axum::Router. Fighting this to keep Actix would require compatibility shims.

4. Tower middleware ecosystem

Axum is built on Tower — the same stack used by hero_rpc_osis, tower-sessions, tower-http. The freezone and all Hero services share this. Actix has its own middleware model that does not compose with Tower.

5. The roadmap says so

Issue #1 explicitly calls for "migrate Actix-Web to Axum + AxumRpcServer" in P1.

What we are NOT changing

Frontend: Tera templates stay (SSR)
Business logic: ServiceProvider DI stays during migration
Data layer: hero_osis calls stay
URLs/behavior: Same endpoints, same responses

It is a framework swap under the same application — same car, different engine, because the engine needs to match the Hero ecosystem garage.

Progress

Axum SSR infrastructure (state, middleware, extractors, response helpers)
Migrate 15 controllers (214 endpoints, 7,540 lines)
Rewrite main.rs, wire routes, remove Actix deps

## Why Actix → Axum ### 1. AxumRpcServer is the Hero runtime `hero_rpc_osis::rpc::AxumRpcServer` — the JSON-RPC 2.0 dispatch layer produced by the code generator — is built on Axum. The freezone backend uses it. Every Hero service uses it. The generated `OsisMarketplace` domain plugs directly into it. Running Actix alongside would mean two web frameworks in one binary for no reason. ### 2. One framework, not two With the RPC server (P1c) we already added Axum as a dependency. Keeping Actix means two async runtimes, two middleware stacks, two sets of extractors, double the dependency tree, and developers needing to know both. ### 3. Generated code expects Axum `osis_server_generated.rs` produces Axum router builders. The service handlers use Axum State pattern. `build_router()` returns `axum::Router`.

P1d Complete: Actix → Axum Migration

Commit: b5faec9

What was done

Axum SSR infrastructure — AppState, security/timer/JWT middleware, SessionUser/OptionalUser extractors, Tera render_template + redirect + json helpers
15 controllers migrated — 214 endpoints, 7,540 lines in axum_app/controllers/
main.rs rewritten — Axum server bootstrap replaces Actix-Web
Legacy Actix code gated behind actix-legacy feature flag
actix-session kept as dependency (service traits use Session type — will refactor in P3)
actix_web::rt replaced with tokio::runtime
JWT generate_token inlined in Axum auth controller

Build status

cargo check — clean (0 errors)
Default build uses Axum exclusively
Legacy controllers available via --features actix-legacy
