# Source Index

This is a handoff snapshot, not the product SSOT.

Product SSOT: mall-docs report-notebooklm docs, snapshot date: 2026-06-03.

## Snapshot Sources

The handoff documents in this repository were distilled from these logical product-document sources:

| Logical source | Used for |
|---|---|
| `phase1-scope.md` | Product positioning, target users, tabs, Phase 1 scope, non-goals, compliance boundary, Vision decoupling. |
| `phase1-build-brief.md` | Data tables, endpoint list, display module model, artifact enum, seed mapping, open questions. |
| `phase1-development-plan.md` | Technology choices, architecture, Redis/object-storage strategy, phases, deployment assumptions, external dependencies. |
| `data-model-api-contract-v0.1.md` | API/data object intent and response boundaries. |
| `user-flows.md` | Guest vs logged-in behavior, shallow interaction expectations, no-download clarification. |
| `app-prd-v0.1.md` | App-side behavior and page-level expectations. |
| `vision-research-sources.md` | Source-reference context and Vision decoupling principle. |

## Drift Rule

Do not treat this repository snapshot as the product SSOT. When product requirements change:

1. Update the product SSOT first.
2. Update this code-repo snapshot only for information needed by engineers.
3. Bump the snapshot date or add a short changelog entry.
