# Implementation Blueprint Starter Canvas — Free Starter
**RELESONA TECHNOLOGIES · Digital Product Store · v1.0 · 24 October 2026**

A useful blueprint is not a decorative architecture diagram. It should tell the reader what to build, what not to build, how to verify it and how to reverse a failed release.

## 1. Product definition
**Working title:**
**Version:**
**Owner:**
**Problem to solve:**
**Target users:**
**Expected business/user outcome:**
**Out of scope:**

## 2. Requirements
| ID | Requirement | Priority | Acceptance evidence |
| --- | --- | --- | --- |
| REQ-001 | [A measurable behavior] | Must / Should | [Test or artifact] |
| REQ-002 | | | |
| REQ-003 | | | |

Write requirements as **observable results**, not vague promises such as “smart”, “seamless” or “fully autonomous”.

## 3. Architecture and boundaries
Describe or draw the path from user to UI, API, database, integrations and external providers. For each component document:
- What it owns.
- What data it may access.
- Its runtime and location.
- Failure mode and safe default.
- How it authenticates.
- Who may approve writes or deployments.
- Where logs and audit evidence live.

## 4. Data model
| Entity | Fields required | Owner | Visibility | Retention |
| --- | --- | --- | --- | --- |
| [Entity] | [Fields] | [Service/role] | [Private/public] | [Period] |

Document relationships, schema validation, backup, migrations, import rules and deletion.

## 5. APIs and integrations
| Interface | Input | Output | Authentication | Failure handling |
| --- | --- | --- | --- | --- |
| [Endpoint/event] | | | | |

Use explicit allowlists and versioned contracts. Do not pass raw third-party tool results directly into privileged actions.

## 6. User journeys
Write one normal path and at least two negative paths:
1. **Normal:** user action → validation → authorized operation → visible confirmation.
2. **Invalid input:** clearly explained failure, no unintended write.
3. **Interrupted provider:** safe retry or rollback, no duplicate charge/action.

## 7. Quality and security gates
- [ ] Identity, role permissions and access boundaries tested.
- [ ] No secret in frontend bundle or public documentation.
- [ ] External content cannot increase its own authority.
- [ ] E2E tests cover success, denial and retry cases.
- [ ] Accessibility and mobile layout reviewed.
- [ ] Performance is measured with environment and conditions stated.
- [ ] Data restoration demonstrated, not just documented.
- [ ] Versions, checksums and licences match actual deliverables.
- [ ] Production release has an independent owner approval gate.

## 8. Delivery stages
| Batch | Deliverable | Acceptance | Rollback | Status |
| --- | --- | --- | --- | --- |
| 01 | Scope + architecture | Reviewed requirements | N/A | Draft |
| 02 | Minimal functional flow | Automated tests | Previous commit | Planned |
| 03 | Data and permissions | RLS / role tests | Schema backup | Planned |
| 04 | UI and real user flow | Responsive E2E evidence | Previous deployment | Planned |
| 05 | Release and operations | Restore + owner sign-off | Verified rollback | Planned |

## 9. Risk register
| Risk | Probability | Impact | Mitigation | Decision owner |
| --- | --- | --- | --- | --- |
| | | | | |

## 10. Handover
- Repository and exact commit:
- Environment assumptions:
- Installation steps:
- Tests and results:
- Known omissions:
- Third-party service costs:
- License / permitted uses:
- Owner of next maintenance cycle:
- Emergency recovery instructions:
