+# Aetherbound Guild Agent Contract
+
+This file narrows the portfolio rules for this repository.
+
+## Current Stage
+
+The repository is design-only. Agents may research, specify, diagram, simulate,
+review, and build non-runtime HTML design prototypes. They may not create game
+runtime code, engine projects, production packages, store records, or bulk final
+art/audio without a later owner-approved Goal.
+
+## Originality Boundary
+
+- Authorized private reference material may be inspected only to identify
+  systems, player decisions, content categories, pacing patterns, and production
+  scope.
+- Do not copy reference names, prose, formulas, layouts, progression trees,
+  source code, art, music, sound effects, or other expressive assets.
+- Do not place third-party commercial assets in this repository.
+- Every product-facing design must be independently authored and traceable to
+  this game's approved product contract.
+
+## Design Completion Gate
+
+Formal development remains frozen until all of these are complete, mutually
+consistent, independently reviewed, and owner-approved:
+
+1. Product and player-experience contract.
+2. Core loop, battle, profession, skill, progression, economy, failure, save,
+   difficulty, and postgame specifications.
+3. Complete 30-character, 36-profession, 100-enemy, 8-chapter, and 320-item
+   content matrices with no filler rows.
+4. Complete screen/state map, onboarding, accessibility, localization, input,
+   error, empty, confirmation, settings, and endgame states.
+5. Art direction, asset inventory, animation matrix, VFX language, music plan,
+   and SFX event catalog.
+6. Landscape HTML design gallery showing every player-facing page and key state.
+7. Economy/build simulations and a decision-density audit.
+8. Interactive design prototype and owner review.
+
+Human visual, comprehension, fun, listening, device, packaging, store, and
+release acceptance remain separate gates.

+# Aetherbound Guild / 裂脉远征团
+
+An original landscape 2D Japanese hand-drawn guild-expedition strategy game.
+
+This repository is currently in **complete pre-production design**. Formal game
+implementation, bulk final-asset production, packaging, and publishing are
+forbidden until the owner approves the complete product, content, presentation,
+balance, and interactive-design package.
+
+## Current Product Boundary
+
+- 30 named recruitable characters
+- 12 base professions and 24 advanced professions
+- 100 enemy combat identities across 8 chapters
+- 320 equipment and item entries
+- 25-35 hour first campaign, 60-80 hour build completion, roughly 100 hour
+  collection and high-difficulty completion target
+- Landscape 16:9, premium cross-platform target, English and Simplified Chinese
+- 2D Japanese hand-drawn presentation using layered rigs, equipment layers,
+  authored key poses, and unique portraits/illustrations
+
+The game may learn structural lessons from authorized private reference
+research, but its setting, characters, enemies, names, art, audio, UI,
+progression, formulas, and expression must be original.
+
+## Design Package
+
+The design package will be developed under `docs/` and published as a reviewable
+HTML gallery before any formal implementation starts.

+# Design Authority Map
+
+Design documents are split by ownership so parallel agents do not edit the same
+files.
+
+- `reference/`: evidence-labeled reference census and transferable lessons
+- `product/`: player contract, systems, economy, balance, save/failure
+- `content/`: characters, professions, enemies, equipment, chapters, collection
+- `presentation/`: screen map, UI, art, animation, assets, audio
+- `prototype/`: HTML gallery and interactive design-prototype specifications
+- `reviews/`: independent consistency and readiness reviews
+
+Status and task ownership live in `.agent-taskgraph/`.
