+# Need-Driven Project Intelligence
+
+Starboard's need-driven intelligence pipeline extracts evidence-backed needs
+from a connected project, searches the eligible repository catalog
+independently for each need, classifies candidates, and produces a structured
+report. An optional external reviewer (e.g., Devin) can validate and refine
+the report through a provider-neutral ingestion contract.
+
+## Pipeline stages
+
+```text
+Connected project
+  → fingerprint (README, manifests, tools, AI metadata, topics)
+  → need extraction (5–10 evidence-backed needs, fewer when insufficient)
+  → per-need retrieval (Vectorize + FTS + structured, cached by signature)
+  → candidate classification (5 buckets with confidence and provenance)
+  → draft report persistence (versioned, incremental reruns)
+  → optional external review ingestion (provider-neutral, idempotent)
+```
+
+## Key design decisions
+
+- **Deterministic first.** Starboard always produces a draft report without
+  any external reviewer. Devin is optional, not required.
+- **Per-need retrieval.** Each need generates focused search intents and
+  queries the full eligible catalog independently. Agents never receive all
+  12k repository records.
+- **Reusable capability cards.** One evidence-backed card per catalog
+  repository, refreshed only when the source fingerprint changes.
+- **Cached candidate pools.** Projects with similar needs reuse retrieval
+  work via normalized need signatures.
+- **Incremental reruns.** A run is skipped when the project fingerprint, need
+  map, and catalog generation are unchanged.
+- **Failure-safe.** Degraded runs preserve the latest successful report.
+  External review failure or budget exhaustion never replaces the draft.
+- **No Devin credentials in Starboard.** Fleet automation owns Devin
+  credentials, session creation, polling, and spend limits. Starboard only
+  ingests structured review results.

+## Classification buckets

+| Bucket | Meaning |
+|--------|---------|
+| `adopt_or_integrate` | Suitable to use now |
+| `reference_implementation` | Study and borrow patterns |

+| `competing_product_to_monitor` | Monitor, not adopt |
+| `unsuitable_negative_example` | Explicitly exclude with rationale |
+
+## API endpoints
+
+- `GET /api/projects/[slug]/intelligence` — read persisted draft and reviewed
+  reports. Pass `?run=1` to trigger a deterministic pipeline run if no report
+  exists. Never triggers external-agent spend.
+- `POST /api/internal/project-intelligence/run` — operator-only pipeline run
+  for a specific project. Requires `AI_GATEWAY_API_KEY` bearer token.
+- `POST /api/internal/external-reviews/ingest` — operator-only review result
+  ingestion. Idempotent via idempotency key. Requires `AI_GATEWAY_API_KEY`.
+
+## Database tables
+
+Migration `0004_need_driven_intelligence.sql` adds:
+
+- `repo_capability_cards` — reusable evidence-backed repository summaries
+- `project_fingerprints` — stable project input fingerprints
+- `project_needs` — extracted needs with signatures and search intents
+- `need_candidate_pools` — cached candidate lists by need signature
+- `project_draft_reports` — deterministic draft reports (versioned, latest flag)
+- `external_review_requests` — idempotent review request tracking
+- `project_reviewed_reports` — final reviewed reports (latest flag)
+
+## Bounds and safety
+
+- Max 10 needs per project, fewer when evidence is insufficient
+- Max 80 semantic candidates, 200 lexical, 120 structured per need
+- Max 8 candidates per need, 50 total across all needs
+- One bounded external review session per changed project
+- All external-repository operations are read-only
+- No production credentials or private data sent to external reviewers
