Related GitHub Issue

Closes: #1816

Follow-up: #1817 (DI through the workspace scope introduced in #1766).

Description

Extract a typed embedder factory registry and individual factories for all eight vector embedding providers.
Extract vector-store creation and dimension resolution into a dedicated factory.
Extract scanner and file-watcher factories with named dependency options and shared batch-size resolution. Log configuration-read failures before falling back to the existing default.
Move validation and exception telemetry into a dedicated validation manager, retaining a temporary proxy.
Remove creation wrappers and assemble services through dedicated factories using one configuration snapshot.
Preserve provider requirements, dimension precedence, validation outcomes, Semble guards, and existing cache wiring.
Add TODOs for scope-owned DI in [ENHANCEMENT] Inject code-index factories through the workspace scope #1817; no DI or manager ownership changes in this PR.

Test Procedure

Run the code-index Vitest suites from the extension package: 673 tests passed across 29 files.
Extension TypeScript check passed.
Repository lint passed through the commit hook; repository type checks passed through the push hook (unchanged packages used Turbo cache).
Regression coverage includes configuration requirements, invalid providers, constructor arguments, fresh instances, dimension fallback/errors, batch-size warnings, service assembly, and validation telemetry.
No lint suppression increases.
Local environment: macOS, Node 24.7.0, pnpm 10.8.1. Hooks warned that Node 22.23.1 is expected; checks passed. CI should verify the supported runtime. No manual extension-host or E2E run performed.

📝 Summary

Summary by CodeRabbit

New Features
- Directory scanning and file watching now use the configured embedding batch size.
Bug Fixes
- Missing embedding-provider settings and invalid or unavailable vector dimensions now produce clearer configuration errors.
- OpenAI-compatible embeddings report specific errors when the base URL or API key is missing.
- Embedder validation failures return an invalid result and record diagnostic details for troubleshooting.

Walkthrough

The code indexing service delegates embedder, vector-store, scanner, and watcher creation to dedicated factories. Embedder validation and embedding batch-size resolution also have dedicated implementations.

Changes

Code indexing service factories

Layer / File(s)	Summary
Embedder configuration and construction `src/services/code-index/interfaces/embedder-factory.ts`, `src/services/code-index/embedders/`, `src/services/code-index/embedders/factories/`, `src/services/code-index/__tests__/service-factory.spec.ts`	Provider-specific factories construct embedders from `CodeIndexConfig`. `EmbedderFactory` dispatches to the matching factory and rejects unsupported providers. Tests cover provider settings, model selection, and unsupported providers.
Vector-store creation and dimensions `src/services/code-index/interfaces/vector-store-factory.ts`, `src/services/code-index/vector-store/vector-store-factory.ts`, `src/services/code-index/vector-store/__tests__/*`, `src/services/code-index/__tests__/service-factory.spec.ts`	`VectorStoreFactory` resolves dimensions and constructs Qdrant stores. Tests cover manual-dimension fallback, invalid dimensions, missing Qdrant URL, and Semble.
Scanner and watcher construction `src/services/code-index/interfaces/directory-scanner-factory.ts`, `src/services/code-index/interfaces/file-watcher-factory.ts`, `src/services/code-index/processors/*`	Scanner and watcher factories pass the resolved embedding batch size to their constructors. The helper returns the configured value or `BATCH_SEGMENT_THRESHOLD` when the setting is absent or configuration access throws.
Service assembly and embedder validation `src/services/code-index/service-factory.ts`, `src/services/code-index/embedders/embedder-validation-manager.ts`, `src/services/code-index/embedders/__tests__/embedder-validation-manager.spec.ts`, `src/services/code-index/__tests__/service-factory.spec.ts`, `src/services/code-index/processors/__tests__/processor-factories.spec.ts`	`CodeIndexServiceFactory` delegates creation to the dedicated factories and validation to `EmbedderValidationManager`. Tests cover validation results and telemetry, dependency wiring, and the unconfigured-indexing path.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Refactor

Merge Risk: 🔵 Low · up to 2c0f9

Users see a different localized error when either OpenAI Compatible setting is missing, though the missing setting is still rejected. Restore the prior message or explicitly accept this bounded compatibility change.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 2c0f9

The reviewed paths preserve the existing provider selection, endpoint configuration, and validation telemetry behavior. No newly introduced security exposure was established, though extension-host behavior was not verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

inferred — The directly reviewed network exposure is code-index embedding traffic and its configured OpenAI-compatible endpoint, not a newly added service or credential authority.

Trust Boundaries and Controls

observed — The new provider registry rejects Semble and provider values that are not its own registered keys. The previous dispatcher also rejected Semble and unsupported provider values.

Looks good - mostly nits, with the exception of the error throwing a key instead of a message.
