+description: Reviews agent changes along Standards and Spec axes. Use when reviewing PRs, auditing generated agents, or checking platform harness compliance.
+---
+
+# Code Review and Quality Assurance
+
+## Overview
+
+Two-axis review process for evaluating platform agent changes. Evaluates code along two independent dimensions — **Standards** (compliance with platform harness standards & coding guidelines) and **Spec** (faithful implementation of issue/PRD contracts).
+
+## When to Use
+
+- Auditing newly generated or refactored `crucible-agent-*` repositories
+- Reviewing pull requests, git diffs, or feature branches
+- Checking compliance with platform harness contracts (`execution-contract.md`, `base-state-contract.md`)
+
+---
+
+## Two-Axis Review Framework
+
+### Axis 1: Standards (Compliance & Code Smells)
+Inspect code against documented platform standards:
+
+- **Harness Boundary**: Verify `crucible-agent-factory-harness` vs `crucible-agents-sdk` boundary rules. No runnable runtime code inside harness standard repos.
+- **Base State Schema**: Verify state schemas extend `BaseAgentState` (`messages`, `errors`, `has_errors`, `workflow_id`, `current_step`, `next_step`).
+- **Container Hardening**: Verify multi-stage Dockerfiles, non-root execution (`UID 10001`), and `/health` probes.
+- **Code Smell Check**: Look for Fowler smells (Duplicated Code, Shotgun Surgery, Speculative Generality, Feature Envy).
+
+### Axis 2: Spec (Requirement & Contract Fidelity)
+Inspect code against the originating specification (`spec/<contract>.md`):
+
+- **Missing/Partial Requirements**: Are all contract endpoints, connector types, and trigger modes fully implemented?
+- **Scope Creep**: Was functionality added that was not requested in the contract spec?
+- **Incorrect Behavior**: Do connector error handling, cursor advancement, or tenant isolation checks deviate from the spec contract?
+
+---
+
+## Review Output Format
+
+```markdown
+## Standards Review
+- [Pass/Fail] Harness & Base State Compliance
+- [Pass/Fail] Container & Security Hardening
+- Findings & Code Smells
+
+## Spec Review
+- [Pass/Fail] Contract & Requirement Coverage
+- Findings & Scope Creep
+
+## Worst Issue Per Axis
+- Standards: <worst issue>
+- Spec: <worst issue>
+```

 # KAB Content Ingestion Agent
 
-Contract-first ingestion for GitHub and SharePoint into a governed KAB-compatible knowledge store. The package is dependency-light and uses injected HTTP, secret, clock, and publisher ports for deterministic tests.
+Contract-first, multi-tenant ingestion for GitHub REST and Microsoft Graph SharePoint into a governed KAB-compatible knowledge store.
 
-## Quick start
+The package is dependency-light, utilizing hexagonal architecture ports (HTTP, SecretStore, Publisher) for deterministic testing and zero-token leakage.
-```bash
+
-python -m pytest -q
+---
-python -m compileall kab_ingestion
+
+## Architecture & Codebase Alignment
+
+The codebase is organized into two primary layers with a unified domain alignment:

+                            +-----------------------------------+
 ```
 
-See `docs/contract.md`, `docs/operations.md`, and `examples/config.yaml`.
+### 1. Core Ingestion Domain Layer (`kab_ingestion/`)
+- **[kab_ingestion/models.py](file:///home/jonathanboniface/platform-engineering/kyndryl-agent-builder/content-ingestion-agent/kab_ingestion/models.py)**: Canonical domain models (`Document`, `ACL`, `Provenance`, `SyncCursor`, `IngestionRequest`, `IngestionResult`).
+- **[kab_ingestion/github.py](file:///home/jonathanboniface/platform-engineering/kyndryl-agent-builder/content-ingestion-agent/kab_ingestion/github.py)** & **[kab_ingestion/sharepoint.py](file:///home/jonathanboniface/platform-engineering/kyndryl-agent-builder/content-ingestion-agent/kab_ingestion/sharepoint.py)**: Source connectors supporting full tree syncs, incremental delta syncs, and webhook event parsing.
+- **[kab_ingestion/orchestrator.py](file:///home/jonathanboniface/platform-engineering/kyndryl-agent-builder/content-ingestion-agent/kab_ingestion/orchestrator.py)**: Fault-tolerant batch sync engine with bounded retries (`max_retries=3`) and dead-lettering.
+- **[kab_ingestion/governance.py](file:///home/jonathanboniface/platform-engineering/kyndryl-agent-builder/content-ingestion-agent/kab_ingestion/governance.py)**: Strict multi-tenant isolation and ACL validation.
 
-## Security
+### 2. Application & Workflow Layer (`app/`)
-Tokens are referenced by secret name, never stored in configuration or logs. Every document carries tenant, source, and ACL metadata; publishers must enforce the same filters at query time.
+- **[app/agent.py](file:///home/jonathanboniface/platform-engineering/kyndryl-agent-builder/content-ingestion-agent/app/agent.py)**: Service factory `create_agent_app()` and `IngestionService`.
+- **[app/card.py](file:///home/jonathanboniface/platform-engineering/kyndryl-agent-builder/content-ingestion-agent/app/card.py)**: Agent discovery card (`AGENT_CARD`).
+- **[app/workflows/ingestion_workflow.py](file:///home/jonathanboniface/platform-engineering/kyndryl-agent-builder/content-ingestion-agent/app/workflows/ingestion_workflow.py)**: 4-Phase LangGraph workflow runner.
+- **[app/routes.py](file:///home/jonathanboniface/platform-engineering/kyndryl-agent-builder/content-ingestion-agent/app/routes.py)**: HTTP REST routes (`/health`, `/card`, `/ingest`).
+
+### 3. Package Re-export Alignment (`app/kab_ingestion`)
+- **`app/kab_ingestion`**: Operates as a lightweight re-export alignment layer. All domain models, connectors, and ports re-export directly from the canonical `kab_ingestion` root package, guaranteeing full backward compatibility and preventing duplicate definitions.
+
+---
+
+## LangGraph 4-Phase Execution Contract
+
+Every ingestion workflow implements the platform's 4-phase execution contract:
+
+1. **Discovery** (`app/nodes/discovery_node.py`): Non-blocking check for existing resources and connector availability.
+2. **Validation** (`app/nodes/validation_node.py`): Validates `IngestionRequest` format and allowed sources; fails fast on error (`has_errors: True` → `END`).
+3. **Generation** (`app/nodes/generation_node.py`): Connects to GitHub/SharePoint source connectors and fetches normalized documents into `fetched_documents`.
+4. **Deployment** (`app/nodes/deployment_node.py`): Enforces governance approval and tenant ACL isolation, publishing approved documents to target storage.
+
+---
+
+## Security & Tenant Isolation
+
+- **Secret References (`secret_ref`)**: Tokens are referenced by secret name (e.g. `secrets/github-read`), never stored in configuration files or logs.
+- **Tenant Isolation & ACLs**: Every document carries `tenant_id` and `ACL {principals, groups, visibility}`. Tenant mismatch results in automatic publish rejection.
+
+---
+
+## Quick Start & Testing
+
+### Running Tests
+```bash
+python -m pytest -q
+```
+
+### Compiling Packages
+```bash
+python -m compileall kab_ingestion app
+```
+
+---
+
+## Documentation References
+
+- **Contract Specification**: [spec/ingestion-contract.md](file:///home/jonathanboniface/platform-engineering/kyndryl-agent-builder/content-ingestion-agent/spec/ingestion-contract.md)
+- **Configuration Example**: [examples/config.yaml](file:///home/jonathanboniface/platform-engineering/kyndryl-agent-builder/content-ingestion-agent/examples/config.yaml)
+- **Kubernetes Manifests**: [k8s/](file:///home/jonathanboniface/platform-engineering/kyndryl-agent-builder/content-ingestion-agent/k8s)

 ## Connector interface
 `full(config) -> (Document[], SyncCursor)`, `incremental(config, cursor, changes?) -> (Document[], SyncCursor)`, and `webhook(config, payload, headers) -> Change[]`. Implementations must be deterministic for the same source revision, scope, and credentials. Config has `connector_id`, `tenant_id`, secret reference, source scope, and non-secret options.

-# Step 1 validation evidence: GitHub SCM connector
-
-## Intent established
-
-Step 1 is the source-specific implementation of the Step 0 connector contract. It is deliberately scoped to GitHub repositories and paths, supports Markdown/plain-text/source files, and has three invocation paths: full synchronization, cursor-based incremental synchronization, and webhook-triggered synchronization. Its observable output is a KAB-compatible normalized document, not a raw GitHub API response.
-
-## Artifact map
-
-| Requirement | Inspectable artifact | Evidence to inspect |
-|---|---|---|
-| Contract adapter | `src/connectors/github.py` | Connector input/output types and normalized-document construction |
-| Repository and path scope | `src/connectors/github.py` | Repository identity, include/exclude globs, and supported-extension filtering |
-| Authenticated retrieval | `src/connectors/github.py` | Managed-secret token injection and authenticated GitHub API requests |
-| Full and incremental sync | `src/connectors/github.py` | Full tree traversal and revision/cursor-based changed-file traversal |
-| Webhook and revision metadata | `src/connectors/github.py` | Push-event SHA/ref parsing, signature verification, and source revision provenance |
-| Regression evidence | `tests/test_github_connector.py` | Focused tests for scope, file types, pagination, cursor updates, signatures, and idempotency |
-| Deterministic inputs | `tests/fixtures/github/` | API payload and webhook fixtures used by the focused tests |
-
-## Platform-compliance checks
-
-- GitHub REST requests are authenticated and paginated; credentials are configuration references rather than document content.
-- A webhook is accepted only after HMAC-SHA256 verification with the configured secret.
-- Repository/path filters are applied before publication, so an event cannot widen a configured scope.
-- Revision SHA, source URL, fetched timestamp, and connector identity are retained as provenance.
-- The synchronization cursor is advanced only from the completed source revision, allowing retry-safe incremental runs.
-- Unsupported binary formats are excluded; Markdown, text, and configured source extensions are normalized into the shared document shape.
-- Tenant and source ACL fields are copied into every emitted document; no cross-tenant fallback is permitted.
-
-## Verification evidence
-
-The focused verification was executed against the Step 1 artifact boundary with:
-
-```text
-python -m pytest tests/test_github_connector.py -q
-python -m compileall src/connectors/github.py
-```
-
-The verification boundary is intentionally narrow: it checks the connector and its fixtures without regenerating or changing Steps 0, 2, 3, 4, 5, or 6. The generation result records the same commands and the contract/platform assertions above so the step has a step-specific, inspectable result rather than relying on a cluster-level result.
