Because the catalog number alone does not reveal a storyline, we can discuss the general content patterns common to S1 releases around the 300‑series range (roughly 2010‑2015):
| Category | Description (General) | |----------|------------------------| | Narrative | Light‑hearted plots (e.g., a college student meeting a classmate, a workplace romance) that serve as a framework for the sexual scenes. | | Casting | Frequently features popular AV idols who have built a fanbase through previous releases, photobooks, or social media. | | Production Values | Professional lighting, set design, and post‑production editing. The visual aesthetic aims for a “glamour” feel rather than a “raw” documentary style. | | Runtime | Typically 90–120 minutes, with the narrative occupying roughly 15–30 minutes and the remainder devoted to the central performance. | | Legal Compliance | All acts depicted conform to Japan’s Article 175 of the Penal Code (the “obscenity law”), which mandates the pixelation (mosaic) of genitalia. The mosaic is applied digitally in post‑production. |
These traits are common across many S1 releases and provide a baseline for what a viewer could expect from a title labeled “SVDVD‑349” without diving into explicit detail.

| # | Given | When | Then |
|---|-------|------|------|
| AC‑1 | A document with ≥ 2 attachments is opened in the viewer. | The UI renders. | The toolbar shows a primary‑styled button labelled “Download All Attachments”. |
| AC‑2 | The button is clicked. | The client calls the zip‑endpoint. | A download prompt appears with filename Document_<docId>_attachments_<timestamp>.zip. |
| AC‑3 | The zip contains every attachment (including hidden ones the user can view). | The download completes. | The ZIP’s internal structure mirrors the original ordering (e.g., attachments/001‑Invoice.pdf). |
| AC‑4 | The total size of all attachments exceeds 500 MB. | The user clicks the button. | The API returns HTTP 413 with JSON error: "PayloadTooLarge", message: "Attachments exceed 500 MB limit." and the UI shows a toast: “Too many files – please download individually or request a larger bundle via Support.” |
| AC‑5 | The request is made by a user lacking download permission for one of the attachments. | The API processes the request. | The response is HTTP 403, and the UI disables the button (grayed out) with tooltip “You do not have permission to download all files.” |
| AC‑6 | The request is made on a mobile Safari browser. | The response returns a streaming ZIP. | The browser shows the native “Share / Save to Files” dialog (no “download‑blocked” warnings). |
| AC‑7 | The zip is generated successfully. | The user opens it locally. | A manifest.txt file exists at the root, containing lines: <checksum> <size> <relative‑path>. |
| AC‑8 | Automated test suite runs. | All unit, integration, and end‑to‑end tests pass. | Coverage for the new endpoint ≥ 90 %, UI interaction tests pass on Chrome, Firefox, Safari, Edge. |
| Trend | How It Manifests | |-------|------------------| | Shift to Digital | By the mid‑2010s, many studios began releasing “Digital Download” versions alongside DVDs, reflecting the global move toward streaming. | | Rise of Idol‑Based Content | Studios capitalized on the popularity of AV idols, building personal brands that extend into social media and live events. | | International Subtitling | To tap into overseas markets, studios started providing English subtitles (often through third‑party licensing), expanding the fanbase beyond Japan. | | Quality Over Quantity | Higher production budgets per title, with more focus on cinematography and set design, aiming to differentiate from lower‑budget “mass‑production” releases. | | Data‑Driven Casting | Performers are often chosen based on analytics (search trends, fan votes), making the industry increasingly responsive to consumer preferences. |

| Layer | Details |
|------|----------|
| Endpoint | GET /api/v1/documents/docId/attachments/zip |
| Auth | Inherit existing JWT + RBAC. Verify DOWNLOAD_ATTACHMENT permission for each attachment; if any fail → 403. |
| Streaming | Use Spring Boot (or equivalent) ResponseBodyEmitter / StreamingResponseBody to stream ZIP on‑the‑fly (no temporary files). |
| Zip Creation | - Use java.util.zip.ZipOutputStream (or Apache Commons Compress).
- Add manifest.txt as the first entry.
- Preserve original filenames; if duplicate names exist, prefix with numeric index. |
| Size Guard | Before streaming, compute total size via metadata query. If > 500 MB → 413. |
| Error Handling | Convert checked exceptions to JSON error responses via @ControllerAdvice. |
| Rate Limiting | Apply existing per‑user API rate limiter (e.g., 10 zip requests/min). |
| Metrics | Increment attachments.zip.request counter, record duration, success/failure tags. |
| Risk | Impact | Mitigation |
|------|--------|------------|
| Large ZIP generation may consume CPU / memory. | Performance degradation on busy servers. | Use streaming, cap size at 500 MB, monitor via metrics, autoscale zip‑service if needed. |
| Mobile browsers sometimes block programmatic downloads. | Users get “download blocked”. | Use a hidden <a> element with href set to object URL and download attribute; fallback to opening in new tab. |
| Users may expect folder hierarchy that does not exist. | Confusion over flat file list. | Include manifest.txt with original ordering; optionally add a “Preserve folder hierarchy” flag in a future iteration. |
| Permission edge‑cases (some attachments private). | 403 errors may be unexpected. | Disable button entirely if any attachment is not downloadable; show tooltip explaining why. |
