Reject explicit invalid tuning values before solution conversion.
When a solution contains bm25_k1 = 0 or rrf_k = 0, solution_converter.cpp omits those fields. The values then cannot reach RetrieveNode for validation and can be replaced by session defaults. A negative bm25_b is also omitted. Validate these values while their presence is still known, before expand_rag converts the solution.

Preserve explicit bm25_b: 0 during solution conversion.
populate_rag parses YAML zero into RAGConfig, but expand_rag only forwards values greater than zero. The reachable retrieve operator then omits bm25_b, so the query uses the session default instead of disabling BM25 length normalization. Preserve field presence in RAGConfig and forward present values, including zero. Invalid values remain subject to the existing retrieve validation.

## ts-proto 2.x Release Notes
The 2.x release of ts-proto migrated the low-level Protobuf serializing that its `encode` and `decode` method use from the venerable `protobufjs` package to `@bufbuild/protobuf`.
If you only used the `encode` and `decode` methods, this should largely be a non-breaking change.
However, if you used any code that used the old `protobufjs` `Writer` or `Reader` classes, you'll need to update your code to use the new `@bufbuild/protobuf` classes:
`import { BinaryReader, BinaryWriter } from "@bufbuild/protobuf/wire";
`
If migrating to `@bufbuild/protobuf` is a blocker for you, you can pin your `ts-proto` version to `1.x`.
Disclaimer & apology: I had intended to release ts-proto 2.x as an alpha release, but didn't get the semantic-release config correct, and so ts-proto 2.x was published as a major release without a proper alpha/beta cycle.
If you could file reports (or better PRs!) for any issues you come across while the release is still fresh, that would be greatly appreciated.
Any tips or tricks for others on the migration would also be appreciated!
The default behavior is `forceLong=number`, which will internally still use the `long` library to encode/decode values on the wire (so you will still see a `util.Long = Long` line in your output), but will convert the `long` values to `number` automatically for you. Note that a runtime error is thrown if, while doing this conversion, a 64-bit value is larger than can be correctly stored as a `number`.
* With `--ts_proto_opt=useJsTypeOverride`, 64-bit numbers will be output as the FieldOption.JSType specified on the field. This takes precedence over the `forceLong` option provided.
* With `--ts_proto_opt=esModuleInterop=true` changes output to be `esModuleInterop` compliant.
Specifically the `Long` imports will be generated as `import Long from 'long'` instead of `import * as Long from 'long'`.
* With `--ts_proto_opt=env=node` or `browser` or `both`, ts-proto will make environment-specific assumptions in your output. This defaults to `both`, which makes no environment-specific assumptions.
Using `node` changes the types of `bytes` from `Uint8Array` to `Buffer` for easier integration with the node ecosystem which generally uses `Buffer`.
Currently `browser` doesn't have any specific behavior other than being "not `node`". It probably will soon/at some point.
* With `--ts_proto_opt=useOptionals=messages` (for message fields) or `--ts_proto_opt=useOptionals=all` (for message and scalar fields), fields are declared as optional keys, e.g. `field?: Message` instead of the default `field: Message | undefined`.
ts-proto defaults to `useOptionals=none` because it:
1. Prevents typos when initializing messages, and
2. Provides the most consistent API to readers
3. Ensures production messages are properly initialized with all fields.

# Implicit Presence
Covers why the Protobuf team regrets implicit field presence
Implicit presence — the proto3 behavior in which a singular scalar field has no hazzer and the value `0`, `false` or `""` is indistinguishable from “never set” — is a design decision the Protobuf team regrets.
We do not recommend using implicit presence for new fields.
* In proto3, prefer to tag your fields `optional`. This is a weak guidance though; if you are still using the Go Open API you may have good reason to choose to prefer implicit presence fields.
* Explicit presence is the silent default in Protobuf Editions going forward.
For the operational details of how presence behaves in each dialect, see the Field Presence application note. This page is about why.
## What Implicit Presence Is
Field presence is whether a message tracks that a field was set, separately from what it was set to.
* Under explicit presence, the message stores a presence bit alongside the value and generates a `has_foo()` hazzer. </excerpt>

# Overview
ts-proto generates TypeScript types from protobuf schemas.
I.e. given a `person.proto` schema like:
message Person {
string name = 1;
}
ts-proto will generate a `person.ts` file like:
interface Person {
name: string
}
const Person = {
encode(person): Writer { ... }
decode(reader): Person { ... }
toJSON(person): unknown { ... }
fromJSON(data): Person { ... }
}
It also knows about services and will generate types for them as well, i.e.:
export interface PingService {
ping(request: PingRequest): Promise<PingResponse>;
}
It will also generate client implementations of `PingService`; currently Twirp, grpc-web, grpc-js and nestjs are supported.
# QuickStart
* `npm install ts-proto`
* `protoc --plugin=./node_modules/.bin/protoc-gen-ts_proto --ts_proto_out=. ./simple.proto`
* (Note that the output parameter name, `ts_proto_out`, is named based on the suffix of the plugin's name, i.e. "ts_proto" suffix in the `--plugin=./node_modules/.bin/protoc-gen-ts_proto` parameter becomes the `_out` prefix, per `protoc`'s CLI conventions.)
* On Windows, use `protoc --plugin=protoc-gen-ts_proto=".\\node_modules\\.bin\\protoc-gen-ts_proto.cmd" --ts_proto_out=. ./simple.proto` (see #93)
* Ensure you're using a modern `protoc` (see installation instructions for your platform, i.e. `protoc` v`3.0.0` doesn't support the `_opt` flag
This will generate `*.ts` source files for the given `*.proto` types.…[truncated]</excerpt>

Preserve explicit zero values in the Web protobuf encoder.
makeRAGQuery forwards the overrides, but the ts-proto generator omits noDefaultsForOptionals. As a result, explicit bm25K1: 0, rrfK: 0, and bm25B: 0 can be omitted by RAGQueryOptions.encode. Core can therefore miss the required zero-value rejection and ignore the valid bm25B = 0 override.
Suggested fix

Update the Web ts-proto generation options used by RAGQueryOptions.encode to
enable noDefaultsForOptionals, so makeRAGQuery preserves explicitly supplied
zero values for bm25K1, bm25B, and rrfK.
