Overall Verdict + +**MINOR AMENDMENTS** + +Most of the RBAC work for `credential-nft` is already done. The plan's "current state" assumptions for `credential-nft` are stale — the code has moved ahead of what the plan describes. The plan's assumptions for `progress-tracker` are mostly correct, with one exception (an `upgrade` function already exists). The plan's items 1 and 2 are largely redundant for `credential-nft`. Items 3–9 are still needed for `progress-tracker` and for tests; the corrected checklist below reflects the real remaining work. + +--- + +## 2. Discrepancies Found + +### Discrepancy A — Plan items 1 & 2: credential-nft RBAC types and wiring are already done + +**Plan assumption (item 1):** +> `metadata.rs` has no RBAC. Needs `AdminRole`, `RoleKey`, `Role(RoleKey)` storage key, and `has_role`/`grant_role`/`revoke_role` helpers added. `events.rs` needs `role_granted`/`role_revoked`. `lib.rs` needs `NotAuthorized = 2` and `panic_with_error` import. + +**Plan assumption (item 2):** +> `mint_credential` currently requires `admin.require_auth()`. `pause`/`unpause` use `(env: Env)` signature. `upgrade` has no `caller`. No public `grant_role`/`revoke_role`/`has_role` exist. + +**Actual code:** +- `contracts/credential-nft/src/metadata.rs` already defines `AdminRole { Admin, Minter, Pauser }`, `RoleKey`, `CredentialDataKey::Role(RoleKey)`, and full `has_role`/`grant_role`/`revoke_role` implementations. Every helper described in item 1 is present. +- `contracts/credential-nft/src/lib.rs` already has `NotAuthorized = 2` in `ContractError`, `panic_with_error` in the import, public `grant_role`/`revoke_role`/`has_role` functions, `mint_credential(env, caller, to, course_id, score, metadata_uri)` gated on `Minter` role, `pause(env, caller)` / `unpause(env, caller)` gated on `Pauser` role, `upgrade(env, caller, new_wasm_hash)` gated on `Admin` role, and `initialize` already calls `metadata::grant_role(&env, &admin, &AdminRole::Admin)`. + +**What still needs doing in credential-nft:** +- `contracts/credential-nft/src/events.rs` does **not** yet have `role_granted` or `role_revoked` event functions. The plan calls for adding them, and the existing `grant_role`/`revoke_role` functions in `lib.rs` already reference `events::role_granted` and `events::role_revoked` (so the contract would not compile without them — but see Discrepancy B below). +- The existing test module in `lib.rs` contains a mix of tests that correctly use the new signature (e.g. `test_pause_emits_paused_event` calls `client.pause(&admin)`) and tests near the bottom that still call `client.mint_credential(&learner, ...)` without the `&admin` caller argument (e.g. `test_mint_rejects_counter_overflow`, `test_minted_event_includes_metadata_uri`). These need updating (plan item 5 still applies to those). + +**Corrected instruction for item 1:** +Skip the `metadata.rs` and `lib.rs` parts of item 1 — they are done. The only remaining sub-task from item 1 is adding `role_granted` and `role_revoked` to `contracts/credential-nft/src/events.rs`. The `grant_role` / `revoke_role` / `has_role` public functions in `lib.rs` should **not** call those event functions if the events don't exist yet (see Discrepancy B). + +**Corrected instruction for item 2:** +Skip entirely. All wiring described in item 2 is already present in `lib.rs`. + +--- + +### Discrepancy B — credential-nft `grant_role`/`revoke_role` call non-existent event functions + +**Plan assumption (item 2):** +> The public `grant_role`/`revoke_role` functions should call `events::role_granted` / `events::role_revoked`. + +**Actual code (lib.rs, already written):** +```rust +pub fn grant_role(env: Env, caller: Address, role: AdminRole, address: Address) { + ... + metadata::grant_role(&env, &address, &role); + events::role_granted(&env, &address, &role); // ← calls events not yet defined +} +pub fn revoke_role(env: Env, caller: Address, role: AdminRole, address: Address) { + ... + metadata::revoke_role(&env, &address, &role); + events::role_revoked(&env, &address, &role); // ← calls events not yet defined +} +``` + +The event functions `role_granted` and `role_revoked` do not exist in `contracts/credential-nft/src/events.rs`. This means the crate currently does **not** compile cleanly. Adding those two functions to `events.rs` is the only remaining step for credential-nft's storage/wiring layer. + +**Corrected instruction:** Item 1 reduces to: add `role_granted(env, address, role)` and `role_revoked(env, address, role)` to `contracts/credential-nft/src/events.rs` with the shapes described in the plan. No other change is needed to `metadata.rs` or `lib.rs`. + +--- + +### Discrepancy C — progress-tracker `upgrade` already exists (plan item 4, sub-step 4) + +**Plan assumption (item 4, sub-step 4):** +> Add a new `upgrade` function — progress-tracker has no upgrade entrypoint today. + +**Actual code:** +`contracts/progress-tracker/src/lib.rs` already contains: +```rust +pub fn upgrade(env: Env, new_wasm_hash: BytesN<32>) { + Self::require_not_paused(&env); + let admin: Address = env.storage().persistent().get(&ProgressTrackerDataKey::Admin)...; + admin.require_auth(); + env.deployer().update_current_contract_wasm(new_wasm_hash.clone()); + types::write_entry(&env, &ProgressTrackerDataKey::WasmHash, &new_wasm_hash); + // bumps Version and calls events::upgraded(...) +} +``` +The `WasmHash` key also already exists in `ProgressTrackerDataKey`. The `events::upgraded` function already exists in `events.rs`. + +**Corrected instruction for item 4, sub-step 4:** Do **not** add a new `upgrade` function. Instead, change the existing one's signature from `pub fn upgrade(env: Env, new_wasm_hash: BytesN<32>)` to `pub fn upgrade(env: Env, caller: Address, new_wasm_hash: BytesN<32>)`, replace the `admin.require_auth()` block with `caller.require_auth()` + `has_role(caller, Admin)` check, and update the event call to match. The body logic (deployer call, WasmHash write, Version bump, events::upgraded) is already correct and should be kept as-is. + +--- + +### Discrepancy D — progress-tracker `pause`/`unpause` are still old-style (plan item 4 is still needed) + +**Plan assumption (item 4, sub-steps 2–3):** +> `pause(env: Env)` and `unpause(env: Env)` use `admin.require_auth()` and need updating to `(env, caller)` + Pauser check. + +**Actual code:** Confirmed. `pause` and `unpause` still have no `caller` parameter and still read + auth against the raw admin address. Plan item 4 sub-steps 2 and 3 are accurate and still needed. + +--- + +### Discrepancy E — progress-tracker `initialize` does not yet call `grant_role` (plan item 4, sub-step 1) + +**Plan assumption (item 4, sub-step 1):** +> After `types::write_entry(&env, &ProgressTrackerDataKey::Admin, &admin)`, add `types::grant_role(&env, &admin, &types::AdminRole::Admin)`. + +**Actual code:** Confirmed. `initialize` writes the `Admin` key but does not call `grant_role`. The `has_role` helper already has a backward-compat path (if address == admin, return true), so the contract will function correctly before this is added, but for consistency with `learn-token` and `credential-nft` the grant call should still be added. + +--- + +### Discrepancy F — progress-tracker `events.rs` has no `role_granted`/`role_revoked` (plan item 3 is still needed) + +**Plan assumption (item 3):** +> `events.rs` needs `role_granted` and `role_revoked`. + +**Actual code:** Confirmed. `contracts/progress-tracker/src/events.rs` has `paused`, `unpaused`, `upgraded`, and all course/learner events, but no role events. + +--- + +### Discrepancy G — progress-tracker `types.rs` RBAC is already done (plan item 3 partial) + +**Plan assumption (item 3):** +> `types.rs` has no RBAC. Needs `AdminRole`, `RoleKey`, `Role(RoleKey)`, and `has_role`/`grant_role`/`revoke_role`. + +**Actual code:** All of these are already present in `contracts/progress-tracker/src/types.rs`. `AdminRole { Admin, Minter, Pauser }`, `RoleKey`, `ProgressTrackerDataKey::Role(RoleKey)`, and `has_role`/`grant_role`/`revoke_role` functions are fully implemented. + +**Corrected instruction for item 3:** The `types.rs` work is complete. Skip those sub-tasks. The remaining work for item 3 is: (a) add `role_granted`/`role_revoked` to `events.rs`, (b) add `NotAuthorized = 1` to `ContractError`, and (c) add `panic_with_error` to the `soroban_sdk` import in `lib.rs`. + +--- + +### Discrepancy H — credential-nft test module has a mix of old and new call sites (plan item 5) + +**Plan assumption (item 5):** +> All `mint_credential` call sites in the test module need `&admin` as the first arg. + +**Actual code:** The tests already updated to match the new signature include `test_pause_emits_paused_event`, `test_unpause_emits_unpaused_event`, the double-pause/not-paused tests, `test_mint_and_verify`, `test_get_credentials_for`, and other tests near the top. However, tests deeper in the file (e.g., `test_mint_rejects_counter_overflow`, `test_minted_event_includes_metadata_uri`, and several others near the bottom of the test module) still call `client.mint_credential(&learner, ...)` without `&admin`. Plan item 5 still applies to those. + +--- + +## 3. Final Ordered Task Checklist (Amended) + +- [ ] 1. Add `role_granted` and `role_revoked` event functions to `contracts/credential-nft/src/events.rs`. + + **What**: The public `grant_role` and `revoke_role` functions in `lib.rs` already call `events::role_granted` and `events::role_revoked`, but those functions do not exist yet, so the crate does not compile. Add them now. Shape: topics `("role_granted"|"role_revoked", address.clone())`, data `(role_symbol,)` where role_str maps Admin→"Admin", Minter→"Minter", Pauser→"Pauser". The `AdminRole` type is in `crate::metadata`; import it or accept the type parameter. *(All `metadata.rs` and `lib.rs` work from the original plan item 1 and item 2 is already done — skip it.)* + + **Files**: `contracts/credential-nft/src/events.rs` + + **Verify**: `cargo check -p credential-nft` — compiles cleanly. + +- [ ] 2. ~~Add RBAC types and storage helpers to `credential-nft/src/metadata.rs`~~ — ALREADY DONE. Skip. + +- [ ] 3. ~~Update `credential-nft/src/lib.rs`: initialize, mint_credential, pause, unpause, upgrade, grant_role, revoke_role, has_role~~ — ALREADY DONE. Skip. + +- [ ] 4. Add RBAC scaffolding to `progress-tracker/src/lib.rs` and `events.rs`; add `NotAuthorized` to `ContractError`. *(Corresponds to original plan item 3.)* + + **What**: The `types.rs` parts of item 3 are already done. What remains: (a) add `role_granted(env, address, role)` and `role_revoked(env, address, role)` to `contracts/progress-tracker/src/events.rs` using the same shape as in `credential-nft` — topics `("role_granted"|"role_revoked", address.clone())`, data `(Symbol::new(env, role_str),)`, importing `AdminRole` from `crate::types`; (b) add `NotAuthorized = 1` to `ContractError` in `lib.rs`; (c) add `panic_with_error` to the `soroban_sdk` import in `lib.rs`. + + **Files**: `contracts/progress-tracker/src/events.rs`, `contracts/progress-tracker/src/lib.rs` + + **Verify**: `cargo check -p progress-tracker` — compiles cleanly. + +- [ ] 5. Update `progress-tracker/src/lib.rs`: initialize, pause, unpause, upgrade, add public grant_role/revoke_role/has_role. *(Corresponds to original plan item 4.)* + + **What**: Wire RBAC into progress-tracker's entrypoints. All five sub-steps from the original plan item 4, with one amendment for sub-step 4: + + 1. **`initialize`**: After `types::write_entry(&env, &ProgressTrackerDataKey::Admin, &admin)`, add `types::grant_role(&env, &admin, &types::AdminRole::Admin);` + + 2. **`pause`**: Change to `pub fn pause(env: Env, caller: Address)`. Replace the admin-read + `admin.require_auth()` block with `caller.require_auth()` + Pauser check. Update event call to `events::paused(&env, &caller, env.ledger().timestamp())`. + + 3. **`unpause`**: Same change as `pause`. + + 4. **`upgrade`** (AMENDED): Do **not** add a new function — one already exists. Change the existing signature from `pub fn upgrade(env: Env, new_wasm_hash: BytesN<32>)` to `pub fn upgrade(env: Env, caller: Address, new_wasm_hash: BytesN<32>)`. Replace the `admin.require_auth()` block with `caller.require_auth()` + `if !types::has_role(&env, &caller, &types::AdminRole::Admin) { panic_with_error!(...) }`. Leave the deployer call, WasmHash write, Version bump, and `events::upgraded` call unchanged. + + 5. **Add public RBAC entrypoints**: `grant_role`, `revoke_role`, `has_role` as described in the original plan. Each should also emit the corresponding `events::role_granted` / `events::role_revoked` event. + + **Files**: `contracts/progress-tracker/src/lib.rs` + + **Verify**: `cargo check -p progress-tracker` — compiles. Some test call sites will have wrong argument counts (fixed in item 6). + +- [ ] 6. Fix remaining stale test call sites in `credential-nft/src/lib.rs` test module. *(Corresponds to original plan item 5, scope narrowed.)* + + **What**: The tests already updated to the new signature can be left alone. Find and fix the tests that still call `client.mint_credential` without `&admin` as the first argument.
