SC-04 — Inadequate Documentation and Missing Safety Invariants

[ayshadogo]

• Quality score: 8/10

• Type: Documentation + Enhancement

• Summary: Document financial guarantees, storage strategy, and safety invariants. Current codebase lacks explanations of: per-asset release calculations, milestone state machine, temporary vs. persistent storage trade-offs, and recovery paths after partial failures. Add comprehensive comments, safety proofs, and operational runbooks.

• Affected files:

  • campaign/src/lib.rs (lines: all major functions need invariant comments)
  • campaign/src/storage.rs (lines: explain TTL strategy and cleanup)
  • common/src/lib.rs (lines: document validation rules)
  • docs/deployment.md (add Operations & Safety section)
  • docs/postgres-ha.md (add state recovery procedures)
  • campaign/src/test.rs (lines: test comments explaining invariant verification)
  • README.md (add contract design section)

• Acceptance criteria:

  • Every public function includes: purpose, parameters, return semantics, panics/errors
  • Financial calculations include comments explaining precision and rounding strategy
  • Storage module documents: why this key uses persistent vs. temporary, TTL implications
  • Add "Safety Invariants" section listing all contract state machine guarantees
  • Document recovery procedures for: incomplete releases, corrupted donor records
  • Create ARCHITECTURE.md describing campaign lifecycle state machine

Hi everyone,

I would love to take this on. My planned approach:

• Implement SC-04 — Inadequate Documentation and Missing Safety Invariants with explicit require_auth checks, clean storage layouts, and robust Soroban contract logic.
• Add comprehensive unit tests verifying both happy-path invocations and unauthorized revert scenarios.

Excited to work on this—please assign to me and I'll submit a clean PR shortly!

Hi maintainers,

I can tackle SC-04 — Inadequate Documentation and Missing Safety Invariants. Proposed implementation roadmap:

• Analysis: Inspect current behavior and edge cases in Dfunder/lumora-contract
• Implementation: Implement SC-04 — Inadequate Documentation and Missing Safety Invariants with explicit require_auth checks, clean storage layouts, and robust Soroban contract logic.
• Testing: Add comprehensive unit tests verifying both happy-path invocations and unauthorized revert scenarios.
• PR: Atomic commit with clean git hygiene and passing CI

Excited to work on this—please assign to me and I'll submit a clean PR shortly!
