Plan — MT-12: Create TenantResolver service + TenantContext#

Summary#

Create TenantResolverService and TenantContext interface in src/tenant/ that resolves incoming webhooks to a tenant context carrying platform provider, LLM provider, and config references. Single-tenant MVP: all requests resolve to the same ENV-based default context. Wire resolution into WebhookController and attach to DispatchEvent.

Files#

File	Action	Description
`src/tenant/tenant-context.interface.ts`	create	`TenantContext` interface with `tenant`, `repoConfig`, `platformProvider`, `llmProvider` fields
`src/tenant/tenant-resolver.service.ts`	create	`TenantResolverService` with `resolveFromWebhook()` and `resolveFromRepo()` — both return default single-tenant context
`src/tenant/tenant-resolver.service.spec.ts`	create	Unit tests: webhook→tenant, repo string→tenant, correct provider instances
`src/tenant/tenant.module.ts`	modify	Export `TenantResolverService`, import `PlatformModule`, `LLMModule`, `CredentialModule`
`src/webhook/dto/dispatch-event.dto.ts`	modify	Add optional `tenantContext?: TenantContext` field to `DispatchEvent` and `DispatchEventParams`
`src/webhook/webhook.controller.ts`	modify	Inject `TenantResolverService`, resolve tenant after adapter normalization, attach to `DispatchEvent`

Steps#

Create src/tenant/tenant-context.interface.ts — define TenantContext importing TenantConfig/RepoConfig from ./tenant-config.interface, PlatformProvider from ../platform/platform-provider.interface, LLMProvider from ../llm/llm-provider.interface.
Create src/tenant/tenant-resolver.service.ts — injectable service that injects TenantConfigService, PlatformProvider (via injection token), LLMProvider (via injection token). Both resolveFromWebhook(platform, headers, body) and resolveFromRepo(repo) extract org/repo info and return the default ENV-based TenantContext. No errors thrown for unrecognized orgs/repos.
Update src/tenant/tenant.module.ts — add TenantResolverService to providers/exports, import PlatformModule, LLMModule, CredentialModule.
Extend DispatchEvent in src/webhook/dto/dispatch-event.dto.ts — add optional tenantContext?: TenantContext to both DispatchEventParams and the DispatchEvent class, assigned in constructor.
Update src/webhook/webhook.controller.ts — inject TenantResolverService, call resolveFromWebhook('github', headers, body) after adapter.normalize(), pass resolved context into DispatchEvent constructor.
Create src/tenant/tenant-resolver.service.spec.ts — test webhook payload resolution, repo string resolution, and that TenantContext carries correct provider instances.

Verification#

tsc --noEmit passes with no type errors
npm run lint passes (zero warnings)
npm run test passes — new spec covers webhook resolution, repo resolution, provider instance correctness

Risks#

Wave 2 dependencies (#345, #347, #348) not yet merged — PlatformProvider, LLMProvider, TenantConfigService, CredentialModule interfaces/modules must exist before this can compile. If not merged, implementation must stub or co-create minimal interfaces.
DispatchEvent is a class with readonly fields — adding tenantContext requires updating the constructor and DispatchEventParams interface; downstream consumers that destructure or serialize DispatchEvent must tolerate the new optional field.
