We will map all properties to a flat warehouse-style structure with fields like `prjCode`, `phaseCode`, `blockCode`, etc. All numeric metrics (e.g. `ownNetWeight`, `netWeight`, `noOfBunches`, `docActQty`, `locArea`) will be natively typed as `number` or `number | null`. An explicit `vector?: number[]` signature will be appended to support 768-dimension embeddings. The `ThoughtPayload` interface structure at the bottom of the file will be preserved exactly.
+ * * **Risk Check:** The method `vectorSearch` in `FFBProductionRepository` (located in `src/FFB/mongo-ffb-production.repository.ts`) relies on an explicit `$project` stage projecting legacy nested parameters `site`, `phase`, and `block`. This method, along with any other service methods querying these nested properties, will experience immediate structural typing failures and return incorrect or empty fields.

+/**
+ * * **Current State:** The existing `src/site/schemas/site.schema.ts` file contains three nested legacy TypeScript interfaces: `Block`, `Phase`, and `Site`. The relationships are maintained using references like `phaseId` and `siteId`, and the entire `Site` interface defines nested arrays for phases/blocks.
+ * * **Intended Mutation:** We will completely eliminate the legacy `Site` interface. We will transform `Phase` and `Block` from plain TypeScript interfaces into concrete Mongoose schema classes decorated with `@Schema()` from `@nestjs/mongoose`. The nested database ObjectId relationships will be replaced with flat business string keys (such as `phaseCode` as a unique business key for Phase, and `phaseCode` as an indexed lookup string for Block) aligned with ADR-001-Flat-Business-Keys. Numeric fields from the master spec will be mapped explicitly as Mongoose numbers (`type: Number`).
+ * * **Risk Check:** Deleting the `Site` interface completely and changing the structure/properties of `Phase` and `Block` (e.g. changing `phaseId` to `phaseCode` and converting `Block` from an interface to a class) will immediately break downstream files like `src/site/repositories/block.repository.ts` and `src/site/repositories/site.repository.ts`, which import these interfaces/classes, query by `phaseId` or populate `Site` hierarchies. Downstream module compiler breakage is expected and accepted during this task phase.

-Choose 1-2 aspects from the following to incorporate naturally:
-- General infrastructure (e.g., well-maintained access roads, proximity to main transport hubs, presence of staff housing)
-- Environmental setting (e.g., rolling hills, river boundaries, dense canopy coverage)
-- Workforce and activity (e.g., active harvesting teams, daily briefings at the muster point, recent replanting efforts)
-- Strategic importance (e.g., central processing site, high-yield territory, pivotal logistical junction)
-
-Guidelines:
-- Maintain a grounded, operational tone.
-- Do not mention the bullet points explicitly; weave them into the narrative.
-- Ensure the length is exactly 2-4 sentences.
