+# Shared File Blob Storage Implementation Plan
+
+> **For agentic workers:** REQUIRED: Use superpowers:subagent-driven-development (if subagents available) or superpowers:executing-plans to implement this plan. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 将网盘文件模型改造成 `StoredFile -> FileBlob` 引用关系，让分享导入与网盘复制复用同一份底层对象，而不是再次写入物理文件。
+
+**Architecture:** 新增独立 `FileBlob` 实体承载真实对象 key、大小和内容类型，`StoredFile` 只保留逻辑目录元数据并引用 `FileBlob`。网盘上传为每个新文件创建新 blob，分享导入和文件复制直接复用 blob；删除时按引用是否归零决定是否删除底层对象。补一个面向旧 `portal_file.storage_name` 数据的一次性回填路径，避免线上旧数据在新模型下失联。
+
+**Tech Stack:** Spring Boot 3.3.8, Spring Data JPA, Java 17, Maven, H2 tests, local filesystem storage, S3-compatible object storage
+

+- Modify: `backend/src/main/java/com/yoyuzh/files/StoredFileRepository.java`
+
+- [ ] **Step 1: Write the failing tests**
+
+Add/update backend tests that expect file copies and share imports to preserve a shared blob id rather than a per-user storage name.
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `cd /Users/mac/Documents/my_site/backend && mvn test -Dtest=FileServiceTest,FileShareControllerIntegrationTest`
+Expected: FAIL because `StoredFile` does not yet expose blob references and current logic still duplicates file content.
+
+- [ ] **Step 3: Write minimal implementation**
+
+Add `FileBlob` entity/repository, move file-object ownership from `StoredFile.storageName` to `StoredFile.blob`, and add repository helpers for blob reference counting / physical size queries.
+
+- [ ] **Step 4: Run test to verify it passes**
+
+Run: `cd /Users/mac/Documents/my_site/backend && mvn test -Dtest=FileServiceTest,FileShareControllerIntegrationTest`
+Expected: PASS for data-model expectations.

+- [ ] **Step 1: Write the failing tests**
+
+Add/update tests for:
+- upload creates a new blob
+- share import reuses the source blob and does not store bytes again
+- file copy reuses the source blob and does not copy bytes again
+- deleting a non-final reference keeps the blob/object alive
+- deleting the final reference removes the blob/object
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `cd /Users/mac/Documents/my_site/backend && mvn test -Dtest=FileServiceTest,FileServiceEdgeCaseTest`
+Expected: FAIL because current service still calls `readFile/storeImportedFile/copyFile/moveFile/renameFile` for ordinary files.
+
+- [ ] **Step 3: Write minimal implementation**
+
+Refactor file upload/download/import/copy/delete to operate on blob object keys. Keep directory behavior metadata-only. Ensure file rename/move/copy no longer trigger physical object mutations, and deletion only removes the object when the last `StoredFile` reference disappears.
+
+- [ ] **Step 4: Run test to verify it passes**
+
+Run: `cd /Users/mac/Documents/my_site/backend && mvn test -Dtest=FileServiceTest,FileServiceEdgeCaseTest`

+
+- [ ] **Step 1: Write the failing test**
+
+Add an integration-path expectation that persisted file rows still download/import correctly after the blob model change.
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `cd /Users/mac/Documents/my_site/backend && mvn test -Dtest=FileShareControllerIntegrationTest`
+Expected: FAIL because legacy `portal_file` rows created without blobs can no longer resolve file content.
+
+- [ ] **Step 3: Write minimal implementation**
+
+Add a startup/on-demand backfill that creates `FileBlob` rows for existing non-directory files using their legacy object key and attaches them to `StoredFile` rows with missing blob references.
+
+- [ ] **Step 4: Run test to verify it passes**
+
+Run: `cd /Users/mac/Documents/my_site/backend && mvn test -Dtest=FileShareControllerIntegrationTest`
+Expected: PASS.
+
+### Task 4: Update Docs And Full Verification
+
+**Files:**
+- Modify: `memory.md`
+- Modify: `docs/architecture.md`
+- Modify: `docs/api-reference.md` (only if API semantics changed)
+
+- [ ] **Step 1: Document the new storage model**
+
+Record that logical file metadata now points to shared blobs, that share import and copy reuse blobs, and that physical keys are global rather than user-path keys.
+
+- [ ] **Step 2: Run full backend verification**
+
+Run: `cd /Users/mac/Documents/my_site/backend && mvn test`
+Expected: PASS.
+
+- [ ] **Step 3: Summarize migration requirement**
+
+In the final handoff, call out that old production data must be backfilled to `FileBlob` rows before or during rollout; otherwise pre-existing files cannot resolve blob references under the new model.

+# Transfer Simple Peer Integration Implementation Plan
+
+> **For agentic workers:** REQUIRED: Use superpowers:subagent-driven-development (if subagents available) or superpowers:executing-plans to implement this plan. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Replace the hand-rolled online transfer WebRTC peer wiring with `simple-peer` while preserving the current pickup-code flow, backend signaling APIs, and offline transfer mode.
+
+**Architecture:** Keep the existing product boundaries: Spring Boot remains a dumb signaling relay and session store, while the React frontend owns online-transfer peer creation and file streaming. Instead of manually managing `RTCPeerConnection`, ICE candidates, and SDP state across sender/receiver pages, introduce a thin `simple-peer` adapter that serializes peer signals through the existing `/api/transfer/sessions/{id}/signals` endpoints and reuses the current transfer control/data protocol.
+
+**Tech Stack:** Vite 6, React 19, TypeScript, node:test, `simple-peer`, existing Spring Boot transfer signaling API.
+
+---
+
+### Task 1: Lock the new peer adapter contract with failing tests
+
+**Files:**
+- Create: `front/src/lib/transfer-peer.test.ts`
+- Create: `front/src/lib/transfer-peer.ts`
+
+- [ ] **Step 1: Write the failing test**
+
+Add tests that assert:
+- local `simple-peer` signal events serialize into a backend-friendly payload
+- incoming backend signal payloads are routed back into the peer instance
+- peer connection lifecycle maps to app-friendly callbacks without exposing raw browser SDP/ICE handling to pages
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `cd front && npm run test -- src/lib/transfer-peer.test.ts`
+
+- [ ] **Step 3: Write minimal implementation**
+
+Create a focused adapter around `simple-peer` with:
+- sender/receiver construction
+- `signal` event forwarding
+- `connect`, `data`, `close`, and `error` callbacks
+- send helpers used by the existing transfer pages
+
+- [ ] **Step 4: Run test to verify it passes**
+
+Run: `cd front && npm run test -- src/lib/transfer-peer.test.ts`
+
+### Task 2: Replace online sender wiring in the desktop and mobile transfer pages
+
+**Files:**
+- Modify: `front/src/pages/Transfer.tsx`
+- Modify: `front/src/mobile-pages/MobileTransfer.tsx`
+- Modify: `front/src/lib/transfer.ts`
+
+- [ ] **Step 1: Write the failing test**
+
+Add or extend focused tests for the new signaling payload shape if needed so the sender path no longer depends on manual offer/answer/ICE branches.
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `cd front && npm run test`
+
+- [ ] **Step 3: Write minimal implementation**
+
+Use the adapter in both sender pages:
+- build an initiator peer instead of a raw `RTCPeerConnection`
+- post serialized peer signals through the existing backend endpoint
+- keep the current file manifest and binary chunk sending protocol
+
+- [ ] **Step 4: Run test to verify it passes**
+
+Run: `cd front && npm run test`
+
+### Task 3: Replace online receiver wiring while keeping the current receive UX
+
+**Files:**
+- Modify: `front/src/pages/TransferReceive.tsx`
+
+- [ ] **Step 1: Write the failing test**
+
+Add or update tests around receiver signal handling and data delivery if gaps remain after Task 2.
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `cd front && npm run test`
+
+- [ ] **Step 3: Write minimal implementation**
+
+Use the adapter in the receiver page:
+- build a non-initiator peer
+- feed backend-delivered signals into it
+- keep the current control messages, archive flow, and netdisk save flow unchanged
+
+- [ ] **Step 4: Run test to verify it passes**
+
+Run: `cd front && npm run test`
+
+### Task 4: Verification and release
+
+**Files:**
+- Modify if required by validation failures: `front/package.json`, `front/package-lock.json`
+
+- [ ] **Step 1: Install the dependency**
+
+Run: `cd front && npm install simple-peer @types/simple-peer`
+
+- [ ] **Step 2: Run frontend tests**
+
+Run: `cd front && npm run test`
+
+- [ ] **Step 3: Run frontend typecheck**
+
+Run: `cd front && npm run lint`
+
+- [ ] **Step 4: Run frontend build**
+
+Run: `cd front && npm run build`
+
+- [ ] **Step 5: Publish the frontend**
+
+Run: `node scripts/deploy-front-oss.mjs`

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
