# Phase 1 Data Model: Product Knowledge Management & Retrieval
|
||
|
|
|
||
|
|
All new models use `cuid()` ids. Refines `docs/06-database-schema.md`'s conceptual
|
||
|
|
`KnowledgeEntry`/`Runbook` shapes with an explicit version-history mechanism (research.md).
|
||
|
|
|
||
|
|
## KnowledgeEntry
|
||
|
|
|
||
|
|
| Field | Type | Notes |
|
||
|
|
|---|---|---|
|
||
|
|
| id | String @id @default(cuid()) | |
|
||
|
|
| code | String | `KB-<PRODUCT>-<SEQ>` style, e.g. `KB-DQ-102` — logical identifier shared across versions |
|
||
|
|
| version | Int @default(1) | |
|
||
|
|
| isCurrentVersion | Boolean @default(true) | Exactly one `true` row per `code` at a time (research.md) |
|
||
|
|
| productId | String | FK → `Product` |
|
||
|
|
| feature | String? | |
|
||
|
|
| type | String | `known_issue` \| `faq` \| `resolution_procedure` \| `operations` |
|
||
|
|
| problem | String? | |
|
||
|
|
| symptoms | String? | |
|
||
|
|
| errorCode | String? | Free-text reference for display; structured linkage is via `ErrorCode`/`KnownIssue` separately |
|
||
|
|
| cause | String? | |
|
||
|
|
| recommendedSolution | String? | |
|
||
|
|
| verificationSteps | String? | |
|
||
|
|
| escalationGuidance | String? | |
|
||
|
|
| status | String @default("draft") | `draft` \| `published` \| `unpublished` |
|
||
|
|
| effectiveDate | DateTime? | Null = effective immediately once published |
|
||
|
|
| categoryScope | String[] | |
|
||
|
|
| validationStatus | String @default("unvalidated") | `unvalidated` \| `validated` |
|
||
|
|
| owner | String? | |
|
||
|
|
| lastReview | DateTime? | |
|
||
|
|
| source | String? | |
|
||
|
|
| createdAt | DateTime @default(now()) | |
|
||
|
|
|
||
|
|
**Constraints**: `@@unique([code, version])`. Index on `(productId, isCurrentVersion, status,
|
||
|
|
effectiveDate)` — the exact shape retrieval queries on.
|
||
|
|
|
||
|
|
**Retrieval eligibility rule** (not a DB constraint, enforced in the repository's query):
|
||
|
|
`isCurrentVersion = true AND status = 'published' AND (effectiveDate IS NULL OR effectiveDate <=
|
||
|
|
now())`.
|
||
|
|
|
||
|
|
## ErrorCode
|
||
|
|
|
||
|
|
| Field | Type | Notes |
|
||
|
|
|---|---|---|
|
||
|
|
| id | String @id @default(cuid()) | |
|
||
|
|
| code | String | e.g. `LAYOUT_PARSE_042` |
|
||
|
|
| productId | String | FK → `Product` |
|
||
|
|
| description | String | |
|
||
|
|
|
||
|
|
**Constraints**: `@@unique([productId, code])` — unique within a product, matching FR-006.
|
||
|
|
|
||
|
|
## KnownIssue
|
||
|
|
|
||
|
|
| Field | Type | Notes |
|
||
|
|
|---|---|---|
|
||
|
|
| id | String @id @default(cuid()) | |
|
||
|
|
| productId | String | FK → `Product` |
|
||
|
|
| errorCodeId | String? | FK → `ErrorCode` |
|
||
|
|
| description | String | |
|
||
|
|
| status | String @default("open") | |
|
||
|
|
|
||
|
|
## Runbook
|
||
|
|
|
||
|
|
| Field | Type | Notes |
|
||
|
|
|---|---|---|
|
||
|
|
| id | String @id @default(cuid()) | |
|
||
|
|
| key | String | Logical identifier shared across versions, e.g. `PDF_HTML_CONVERSION_FAILURE` |
|
||
|
|
| version | Int @default(1) | |
|
||
|
|
| isCurrentVersion | Boolean @default(true) | Same version-history mechanism as `KnowledgeEntry` |
|
||
|
|
| productId | String | FK → `Product` |
|
||
|
|
| steps | Json | Ordered array — order preserved exactly as authored (FR-008) |
|
||
|
|
| active | Boolean @default(true) | |
|
||
|
|
|
||
|
|
**Constraints**: `@@unique([key, productId, version])`. Lookup-by-key queries filter
|
||
|
|
`isCurrentVersion = true AND active = true`.
|
||
|
|
|
||
|
|
## Product (relations added by this feature)
|
||
|
|
|
||
|
|
`knowledgeEntries KnowledgeEntry[]`, `errorCodes ErrorCode[]`, `knownIssues KnownIssue[]`,
|
||
|
|
`runbooks Runbook[]` — the forward relations doc 06 already specified on `Product` but that
|
||
|
|
couldn't be added until these models existed.
