Awesome Sails VFT

Goal

Help the builder add a fungible token layer to a standard Gear/Vara Sails app through awesome-sails without reimplementing standard token behavior from scratch.

Local Handbook

• ../../references/gear-sails-production-patterns.md
• ../../references/sails-program-and-service-architecture.md
• ../../references/sails-idl-client-pipeline.md
• ../../references/sails-gtest-and-local-validation.md
• ../../references/sails-cheatsheet.md
• ../../references/awesome-sails-token-patterns.md

Local Assets

• assets/token-scope-checklist.md
• assets/token-crate-chooser.md
• assets/token-gtest-matrix.md

Required Sequence

1. Define token intent and deployment shape with assets/token-scope-checklist.md.
2. Choose the smallest awesome-sails token stack with assets/token-crate-chooser.md.
3. Decide whether the token lives as a dedicated program or as embedded token-related services.
4. Name the role model and event model explicitly.
5. Keep the IDL and generated client path intact.
6. Write and execute the selected tests from assets/token-gtest-matrix.md.
7. Route to local smoke only after green gtest.

Crate Selection Rules

• Use the smallest awesome-sails surface that satisfies the feature.
• Prefer base VFT-compatible behavior over custom token logic.
• Add admin and RBAC layers only when the spec requires privileged token operations.
• Add native-exchange only when value↔token conversion is part of the design.

Dependency Source Rules

Prefer one of:

• crates.io version dependencies
• pinned git dependencies
• repository-relative path dependencies only for intentional local co-development

Do not use absolute paths into ~/.cargo/git/checkouts, target, or other machine-local caches.

Guardrails

• Do not write a custom fungible token from scratch when awesome-sails already covers the standard path.
• Do not mix unrelated token policy decisions into implementation before the spec is written.
• Do not bypass IDL/generated clients for the normal token path.
• Do not treat token events as optional for production-facing state transitions.
• Do not make every app build its own mint/burn/allowance logic ad hoc.
• Do not point dependencies to ~/.cargo/git/checkouts/... or other machine-local Cargo cache paths.
• Prefer crates.io versions, a pinned git dependency, or a repository-relative path only when the project intentionally vendors or co-develops the dependency.
