Phase 9.0 Web Preview Delivery

Owner Authorization

On 2026-08-12 the Owner requested a dedicated remote H5 page for phone review of the accepted P9.0 runtime candidate. This authorizes only a Godot Web export, local browser verification and private Artifact Gallery deployment.

Content Boundary

• Product behavior authority remains P9.0 source f881920b1be29933169950429d4e55d8cac825d8; the Web-compatible successor may add only the embedded font, stream-playback selection, export configuration and capture-harness cleanup required by this delivery.
• The Web package may expose the preserved Contract page only through the already accepted Start New Game handoff.
• It may not change Boot, Title, Contract, Recruit, Market, battle, economy, save, art, audio or content authority.
• Tests, evidence, build outputs, source documents and repository history must not be included in the exported PCK.

Delivery Contract

• Preset: Web Preview in runtime/export_presets.cfg.
• Template: Godot 4.6.1 non-threaded Web release, so the private remote page does not require cross-origin isolation headers.
• Canvas: browser-window responsive, canvas focused on startup, experimental mobile virtual keyboard enabled.
• Portrait phones show an explicit rotate-to-landscape overlay instead of a tiny letterboxed game canvas; rotating to landscape reveals the game.
• Local output: ignored runtime/build/web-preview/<product-source>/.
• Remote output: the smallest self-contained export directory, published as a dedicated Artifact Gallery HTML item.

Verify export success, expected HTML/JS/WASM/PCK files, exact ZIP data-package contents with zero tests/, evidence/ or build/ entries, local HTTP loading, real browser canvas dimensions, portrait rotation guidance, one canvas click and the Start New Game handoff. Verify the Gallery health and signed share URL after publication.

The browser build embeds runtime/assets/fonts/NotoSansSC.ttf and its runtime/assets/fonts/OFL.txt license so Simplified Chinese does not depend on a host font. PrototypeSFX must use Godot stream playback; a Web backend may not select sample playback for AudioStreamGenerator.

This is a browser preview, not physical-device, packaging, store, publishing or release acceptance. Owner review of the remote page remains a human gate.

Remote Delivery

Fixed Web source f0aa84738041cebf4968d91c6bf170668804e203 is published as private Artifact Gallery item PRji-yhJo0nQ. The signed item URL redirects to the full-screen index.html only after setting an artifact-scoped HttpOnly cookie; the signing token is not stored in this repository. Direct access without that cookie still reaches the Gallery login boundary.

Remote verification confirms correct JavaScript, WASM and PCK response types, a runtime CSP without the document sandbox, successful Godot/WASM startup, Simplified Chinese Title rendering in the requested landscape phone viewport, the real canvas Start New Game handoff to Contract, and the portrait rotate overlay. Browser warning/error count is zero. Artifact Gallery retains its document sandbox for ordinary HTML; executable delivery requires an explicit runtime-html manifest kind.

The final source-bound evidence inventory verifies 34/34 with SHA-256 cb3111f86012d313c85d1eebed6574b8b5936531bf30821421f89f1442aeb945.
