Add config store read path and split storage module#548
Conversation
Rename crates/common → crates/trusted-server-core and crates/fastly → crates/trusted-server-adapter-fastly following the EdgeZero naming convention. Add EdgeZero workspace dependencies pinned to rev 170b74b. Update all references across docs, CI workflows, scripts, agent files, and configuration.
Introduces trusted-server-core::platform with PlatformConfigStore, PlatformSecretStore, PlatformKvStore, PlatformBackend, PlatformHttpClient, and PlatformGeo traits alongside ClientInfo, PlatformError, and RuntimeServices. Wires the Fastly adapter implementations and threads RuntimeServices into route_request. Moves GeoInfo to platform/types as platform-neutral data and adds geo_from_fastly for field mapping.

- Defer KV store opening: replace early error return with a local UnavailableKvStore fallback so routes that do not need synthetic ID access succeed when the KV store is missing or temporarily unavailable - Use ConfigStore::try_open + try_get and SecretStore::try_get throughout FastlyPlatformConfigStore and FastlyPlatformSecretStore to honour the Result contract instead of panicking on open/lookup failure - Encapsulate RuntimeServices service fields as pub(crate) with public getter methods (config_store, secret_store, backend, http_client, geo) and a pub new() constructor; adapter updated to use new() - Reference #487 in FastlyPlatformHttpClient stub (PR 6 implements it) - Remove unused KvPage re-export from platform/mod.rs - Use super::KvHandle shorthand in RuntimeServices::kv_handle()
- Split fastly_storage.rs into storage/{config_store,secret_store,api_client,mod}.rs
- Add PlatformConfigStore read path via FastlyPlatformConfigStore::get using ConfigStore::try_open/try_get
- Add PlatformError::NotImplemented variant; stub write methods on FastlyPlatformConfigStore and FastlyPlatformSecretStore
- Add StoreName/StoreId newtypes with From<String>, From<&str>, AsRef<str>
- Add UnavailableKvStore to core platform module
- Add RuntimeServicesBuilder replacing 7-arg constructor
- Migrate get_active_jwks and handle_trusted_server_discovery to use &RuntimeServices
- Update call sites in signing.rs, rotation.rs, main.rs
- Add success-path test for handle_trusted_server_discovery using StubJwksConfigStore
- Fix test_parse_cookies_to_jar_empty typo (was emtpy)

Review Summary
Well-structured PR — the storage module split is clean, the PlatformConfigStore read path is correctly implemented, and the migration to &RuntimeServices preserves error context properly. No blockers. CI is fully green.
Highlights:
- Strong newtype pattern for
StoreName/StoreIdprevents mix-up bugs RuntimeServicesBuilderwith exhaustiveexpect("should ...")messages- Graceful KV store degradation with
UnavailableKvStorefallback - Excellent

🤔 [P2] Value not URL-encoded (pre-existing) — crates/trusted-server-core/src/storage/api_client.rs line 122
The payload format!("item_value={}", value) sends application/x-www-form-urlencoded content but doesn't actually URL-encode value. If value contains &, =, +, spaces, or JSON characters ({, }, "), the Fastly API may misinterpret it. This is pre-existing code (moved from fastly_storage.rs) but worth flagging since it's used in key rotation.
Consider: let payload = format!("item_value={}", urlencoding::encode(value));
