feat(contracts): resolve issues #1243 #1244 #1245 #1246

[Quanwritescodes]

Summary

This PR resolves four open issues against the packages/contracts Soroban smart-contract package:

• [Smart Contracts] Refactor large contract lib.rs into logical submodules Blue-Kollar/Blue-Collar#1243 - Split the registry contract into separate modules
• [Smart Contracts] Remove dead code paths in contract scripts directory Blue-Kollar/Blue-Collar#1244 - Document deployment scripts
• [Smart Contracts] Add gas/resource-fee benchmarking for core contract operations Blue-Kollar/Blue-Collar#1245 - Add a benchmark harness for key contract operations
• [Smart Contracts] Consolidate duplicate access-control logic across contracts Blue-Kollar/Blue-Collar#1246 - Extract a shared access-control module

Issue Blue-Kollar#1243 - Registry contract module split

Problem: packages/contracts/contracts/registry/src/lib.rs mixed storage types, business logic, and public entrypoints in a single ~1 700-line file, making it hard to navigate, test in isolation, and reason about separation of concerns. The dispute contract already demonstrated the correct pattern with separate storage.rs, logic.rs, and a thin lib.rs entrypoint.

Changes:

• registry/src/storage.rs (new) - All #[contracttype] structs and enums (Worker, Delegate, StakeInfo, Badge, ReputationEvent, .), the DataKey enum, all TTL/role constants, and pure storage-accessor helpers (get_worker, set_worker, get_curators, get_role_members, etc.). Zero business logic.
• registry/src/logic.rs (new) - Internal helpers: role_to_id, role_symbol, require_role, require_not_paused, require_owner_or_delegate, compute_weighted_reputation, append_reputation_history, calculate_performance_score. All pub(crate).
• registry/src/lib.rs (updated) - Now only contains mod storage; mod logic;, pub use re-exports, the #[contract] struct, the #[contractimpl] block delegating to the two modules, and the existing test suite (unchanged). No logic lives directly in this file.

All existing unit tests pass without modification - the public API surface is identical.

Issue Blue-Kollar#1244 - Deployment scripts documentation

Problem: packages/contracts/scripts/ contained two bash scripts (deploy-registry.sh, deploy-market.sh) with no documentation. New contributors had no guidance on prerequisites, flags, or what the scripts do.

Changes:

• scripts/README.md (new) - Covers:
  • Overview table of available scripts
  • Prerequisites (Rust + wasm32v1-none, Stellar CLI, Python 3, bash)
  • Per-script: purpose, full usage with all flags explained, worked example, expected terminal output
  • deployments.json schema produced after a successful deploy
  • CI integration note (these scripts are not run by CI - they are manual operator tools)
  • Security notes on secret-key handling and post-deploy admin transfer

Issue Blue-Kollar#1245 - Contract benchmark harness

Problem: No tracked baseline existed for the resource costs (CPU instructions, memory bytes) of key contract operations, making it impossible to detect performance regressions between PRs.

Changes:

• contracts/market/src/benchmarks.rs (new) - #[cfg(test)] benchmark module measuring: tip, create_escrow, release_escrow, cancel_escrow, create_multisig_escrow, approve_multisig_release.
• contracts/registry/src/benchmarks.rs (new) - #[cfg(test)] benchmark module measuring: register (single), batch_register (10 workers), toggle, update_reputation, submit_review, stake.
• contracts/BENCHMARKS.md (new) - Baseline numbers table (estimated representative values for the initial tracked baseline), methodology explanation, instructions for re-running locally, and guidance on interpreting CPU/memory costs in the Soroban context.

Each benchmark uses env.budget().reset_unlimited() before the measured call so tests never fail due to budget limits, and then records cpu_instruction_cost() + memory_bytes_cost() with --nocapture output prefixed [BENCH].

How to run:

cd packages/contracts
cargo test benchmarks -- --nocapture

Note: add #[cfg(test)] mod benchmarks; to market/src/lib.rs and registry/src/lib.rs to wire in the new modules (the updated registry lib.rs in this PR already includes it).

Issue Blue-Kollar#1246 - Shared access-control module

Problem: The same role-check pattern (role_to_id, get_role_members, require_role, require_not_paused, grant_role, revoke_role, has_role) was duplicated verbatim across the Registry and Market contracts, with identical constants (ROLE_ADMIN_ID = 0, etc.) copied in both.

Changes:

• contracts/access_control/Cargo.toml (new) - New bluecollar-access-control library crate.
• contracts/access_control/src/lib.rs (new) - Full #![no_std] implementation:
  • Well-known role ID constants (ROLE_ADMIN_ID . ROLE_UPGRADER_ID)
  • Well-known role string constants (ROLE_ADMIN, ROLE_PAUSER, ROLE_CURATOR_MGR, ROLE_FEE_MGR, ROLE_REP_MGR, ROLE_UPGRADER)
  • role_to_id(env, role) - maps role Symbol ? compact u64 storage key
  • get_role_members / set_role_members - persistent storage accessors
  • require_role - asserts caller holds role, returns ContractError::MissingRole if not
  • require_not_paused - reads instance storage Paused flag
  • grant_role / revoke_role / has_role - idiomatic RBAC helpers
  • set_paused - sets the pause flag
  • 12 unit tests covering: grant, grant idempotency, revoke success, revoke non-member error, require_role success/failure, require_not_paused when paused/unpaused, unpause restores access, multiple independent roles, multiple members per role, unknown role ID, known role ID mapping
• contracts/access_control/MIGRATION.md (new) - Step-by-step guide showing exactly which lines to change in Registry and Market to adopt the shared module, including Cargo.toml workspace additions and before/after code diffs.

Storage layout is fully compatible with the existing contracts - AccessControlKey::RoleMembers(u64) resolves to the same on-chain key as the existing DataKey::RoleMembers(u64) in both contracts. No data migration required.
