The uups-bank-demo wave's SDD records (ledger, six task briefs and reports, review diffs) and the brainstorm design mockups were git-ignored, so they existed only on one sandbox VM and reached no remote — this repo had no remote at all until now. Removes `.superpowers/` from .gitignore and the `*` .gitignore the superpowers plugin writes inside .superpowers/sdd/; the second blocks the directory even with the first removed. Excluded as ephemeral local-server state, and now ignored by name: .last-port, .last-token (a 64-char session token for a brainstorm server on a port that is long gone), and the per-session state/ directories.

Task 2 Report: Valueless Six-Decimal Mock Asset
Implementation
Added MockUSDC, an educational ERC-20 mock with no monetary value. It uses OpenZeppelin ERC20 and Ownable, initializes the token as Mock USD Coin (mUSDC), overrides decimals() to return 6, and permits mint(address,uint256) only to the configured owner. OpenZeppelin rejects address(0) as the initial owner via OwnableInvalidOwner.
Changed Files
src/MockUSDC.sol(new): minimal six-decimal owner-mintable ERC-20 mock.test/MockUSDC.t.sol(new): focused tests for metadata, zero supply, authorized/unauthorized minting, transfer, approval, and zero-owner rejection.
TDD Evidence
Before writing production code, the test suite was added. The production change that each test guards was identified as a missing or incorrect ERC-20 observable behavior: metadata/decimals, initial supply, owner authorization and mint balances, transfer balance movement, approval allowance, or constructor owner validation.
RED
Command:
PATH=/home/golem/.foundry/bin:$PATH forge test --match-path test/MockUSDC.t.sol -vvv --force
Relevant output:
Error (6275): Source "src/MockUSDC.sol" not found: File not found.
--> test/MockUSDC.t.sol:6:1:
Error: Compilation failed
This was the expected RED result: the test imports the intentionally absent src/MockUSDC.sol; it failed because the requested feature did not yet exist, not because of a test typo or unrelated failure.
GREEN
Commands:
PATH=/home/golem/.foundry/bin:$PATH forge fmt
PATH=/home/golem/.foundry/bin:$PATH forge test --match-path test/MockUSDC.t.sol -vvv --force
Relevant output:
Ran 7 tests for test/MockUSDC.t.sol:MockUSDCTest
Suite result: ok. 7 passed; 0 failed; 0 skipped
Full Relevant Suite
Command:
PATH=/home/golem/.foundry/bin:$PATH forge test -vvv
Result:
Ran 1 test suite: 7 tests passed, 0 failed, 0 skipped (7 total tests)
git diff --check also completed without reporting whitespace errors.
Self-Review
- Implementation contains only the briefed
ERC20,Ownable,decimals, and owner-onlymintbehavior; no faucet, burn, permit, blacklist, proxy, or bank-specific logic was added. - Tests exercise the deployed contract's observable state and OpenZeppelin's real authorization behavior; no mocks were used.
- The non-owner case uses the required exact
Ownable.OwnableUnauthorizedAccountselector andstrangeraddress. - Mutations such as changing metadata/decimals, allowing arbitrary minting, omitting minting, misrouting transfers, failing to set allowance, or accepting a zero owner are covered by at least one test.
Concerns
None. The report itself is intentionally left uncommitted because the task required committing only src/MockUSDC.sol and test/MockUSDC.t.sol.
Fix Round 1: Literal Command Evidence
Foundry was placed on PATH before each command session with a separate shell environment setup step. The commands below were then executed literally, with no inline PATH prefix.
Isolated RED Reproduction
An isolated temporary filesystem copy of the complete worktree (including the already-installed pinned dependencies) was created under /tmp, and only src/MockUSDC.sol was removed from that copy. This keeps the real committed worktree untouched while preserving the same test file and dependency graph.
Covering test file: test/MockUSDC.t.sol
Literal command:
forge test --match-path test/MockUSDC.t.sol -vvv --force
Relevant output:
Error (6275): Source "src/MockUSDC.sol" not found: File not found.
--> test/MockUSDC.t.sol:6:1:
Error: Compilation failed
This RED result is correct because the isolated state retains the new test but deliberately lacks the production contract it imports. The failure is therefore the expected feature-missing failure, rather than a dependency, compiler, or test error.
Real-Worktree GREEN
Literal commands:
forge fmt
forge test --match-path test/MockUSDC.t.sol -vvv --force
Relevant output:
Ran 7 tests for test/MockUSDC.t.sol:MockUSDCTest
Suite result: ok. 7 passed; 0 failed; 0 skipped

Literal command:
forge test -vvv
Result:
Ran 1 test suite: 7 tests passed, 0 failed, 0 skipped (7 total tests)
No tracked implementation or test file changed during this correction, so no tracked commit was needed. Commit 1f4175b feat: add valueless mock USDC remains the sole task commit.
