The merge hardens this with strict DTO/error projection, account-isolated local state, bounded same-origin downloads/packages, a nonce-protected account-bound player HTTP session, and an exact-source/origin single-document iframe bridge.

 - 2026-08-17: Created merge commit `4013edc` for the reviewed per-user module-entry policy source tip `3b799af`. Main exposes only four booleans from `/api/auth/me`; missing fields remain enabled, `design` maps to `painting`, disabled root/deep/alias routes stop before module initialization, Code provider startup waits for policy hydration, terminal `401` clears both session layers, and global settings remains reachable.
 - 2026-08-17: Integrated remote `01bee31`: Learning is enabled with course browsing, strict bounded generation materials, verified atomic course installation, multi-module playback, Main-owned Agent/ASR/runtime bridges, and a manifest-verified external OpenMAIC player artifact. Merge review added account-isolated generation/library/player state, fixed-binding token/fetch/401 guards, passive-only course media with hardened responses, pre-existing active-registration checks before side-effect-free identity resolution, nonce-protected single-document player sessions, and a recoverable deep-link profile error gate. At that integration checkpoint, publishing used a coverless first create, existing draft/published were version-only, and races failed closed without cover/PATCH side effects; project-cover source `145a6ce` and matching server merge `0cedfc4` above supersede only the coverless-first-create limitation. The transient `game-engine` Skill was removed and `planning-with-files` writes its files to the project root. Production Works/player-artifact/signed-package acceptance remains pending.
 - 2026-08-16: Integrated remote `26b52d7`: Canvas now has server-backed Prompt Museum navigation, editable server-repriced generation Quotes, task result details/downloads, guarded project deletion, cloud-default development, and Chinese-only UI. That tip briefly bundled `game-engine`; authoritative successor `01bee31` removed it. Client integration is verified separately from production Prompt Museum data/backend deployment.
+- 2026-08-18: Integrated Prompt Museum media rendering from `f8d82e6`: relative protected media is fetched through Main with bounded trusted-raster validation and one 401 refresh, HTTPS media remains direct, invalid/failed images are card-local placeholders, and missing attribution URLs render without broken links. Focused unit/Electron E2E, typecheck, scoped lint, and Vite build passed; real Works/CDN production smoke remains pending.
 - 2026-08-16: Integrated Windows/macOS in-page Robot hotspot discovery, explicit selection, connection, and exact-current-SSID verification behind the existing default-on guided capability. Candidate IDs are bounded and short-lived, native diagnostics stay in Main, system settings remain fallback, and firmware/Portal/Binding contracts are unchanged.
 - 2026-08-16: Enabled the existing Guided Hotspot Binding journey by default after explicit product confirmation. Exact `NIANCODE_AI_HARDWARE_GUIDED_HOTSPOT_BINDING=0` remains the operational rollback; fixed portal ownership, direct-code fallback, security warnings, firmware-zero-change, and Binding-without-online semantics are preserved.
 - 2026-08-16: Initially implemented ADR-002's Robot onboarding V1 without changing firmware, behind a default-off Main capability and fixed portal opener. The later `b78fc07` decision above changes only the default; the same firmware/issuer/native-opener/physical evidence remains outstanding.

 ## Risky Areas
 
 - 四模块权限只控制 Makelore 客户端入口和初始化，不是 API 授权边界。不得因卡片置灰或路由阻断而放宽 Works/模块服务端的身份与权限校验；旧服务端缺少对象/字段时默认开启是显式兼容策略。
+- Prompt Museum 相对媒体必须保持固定的服务端路径并由 Main 处理；如果服务端增加媒体变体，需同步维护 entry/path 语法、Works Bearer 所有权、单次刷新、10 MiB 限制、可信 raster MIME 白名单与 Renderer data URL 校验。HTTPS 直连媒体必须继续无凭据，图片失败必须局限在卡片/详情视图。
 - Learning 的课程目录、生成、Agent、ASR 与 runtime 都依赖真实 Works 权益和服务端契约；本地课程归档与播放器 artifact 必须在信任前完成边界、大小与摘要校验。账号分区/epoch、fixed-binding token+fetch guards、同源重定向、512 MiB 上限、player nonce、exact source/origin 与单文档 bridge 边界不可放宽；不得把模块/场景自报身份当成 aggregate 课程权益，也不得把上游错误、Token、内部 URL 或本地归档路径投影到 Renderer。
 - Works Project 首次封面已由服务端源 `407c883`（本地 merge `0cedfc4`）提供单请求原子绑定与失败补偿，客户端源 `145a6ce` 因此要求首次发布上传 PNG/JPEG/WebP 封面；部署、安装包和真实账号/对象存储 smoke 仍未完成。服务端仍没有已有 metadata 的 revision/ETag 与 draft-only 条件写，因此已有 draft/published 继续只允许 version-only，客户端不得以无条件 PATCH 替代。
 - Guided Hotspot Binding 默认开启并提供未经认证的热点扫描/显式连接，但当前 Hotspot/portal 仍是开放 SoftAP + 明文 HTTP，且精确出货镜像、激活码发行契约、签名 macOS、Windows 真机与完整整链尚未验证。界面必须保留环境警告，异常发布可用精确环境值 `0` 回滚；不得把 SSID 前缀宣称为可信设备发现、自动认领或在线证明。

+# Task: Publish Prompt Museum media fix on main
+
+## Identity
+
+- Task ID: 20260818-museum-media-main-8c2d
+- Mode: Integration
+- Branch: main
+- Worktree: D:\Datas\OthersProjects\makelore
+- Base commit: 11b19832a35477d2136c6ea953dd9c408fd84816
+- Owner: developer
+- Status: Completed
+
+## Scope
+
+- Publish the completed Prompt Museum media-rendering change from integration commit `22bee1d` onto the occupied `main` worktree, preserving the source code/tests and accepted canonical documentation updates.
+- Keep the source feature task record out of the canonical tree; integration records remain task-scoped and the source worktree remains read-only.
+
+## Intent And Constraints
+
+- Preserve the Main-owned fixed relative media route, Works Bearer refresh behavior, 10 MiB/trusted-raster limits, Renderer data-URL validation, direct HTTPS images, and local failure placeholders.
+- The merge must not claim production Works/CDN, real-account, signed-package, or deployment acceptance; it must leave `main` clean and the integration lock releasable.
+
+## Outcome
+
+- Merged integration commit `22bee1d` into `main` with an explicit non-fast-forward merge; the final tree contains the Prompt Museum Main proxy, shared DTO, Renderer media conversion/page behavior, focused tests, and canonical state/evidence/commitment updates.
+- Removed only the intermediate integration task record from the merge result; this final task record is the canonical integration note.
+
+## Verification
+
+- `git merge --no-ff --no-commit 22bee1d`: PASS; automatic merge had no conflicts.
+- Focused Prompt Museum verification inherited from the independently reviewed source: 3 files / 27 unit tests, typecheck, scoped ESLint, Vite build, targeted Electron E2E 1/1, `git diff --check`, and final Sol review PASS.
+- Main task-aware drift check and final clean-worktree check will run before releasing ownership.
+
+## Follow-ups
+
+- Real Works account, deployed media endpoint/CDN, and signed-package smoke remain release follow-ups.
+
+## Promotion Candidates
+
+- `current-state.md`, `50-evidence/evidence-index.md`, and `80-commitments/commitments.md` now record the bounded Main proxy and the remaining production acceptance obligation.
