text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add 134 new tests (79 → 213) covering boundary conditions, error cases, and edge cases across all modules: - shared/types: 16 tests for re-exports, Hex edge cases (empty bytes, uppercase, mixed case, large arrays) - shared/errors: 9 new tests for ChopError (unicode messages, empty messages, cause chaining, long messages, catchAll) - cli/errors: 6 new tests for CliError (empty messages, special chars, non-Error causes, object causes, catchAll) - cli/commands/abi: 103 new tests including: - parseSignature boundary: whitespace, underscored names, invalid names (numbers, dots, hyphens), trailing garbage, many params, nested tuples, empty outputs - coerceArgValue boundary: uint256 max/zero, int256 min, zero/max address, empty bytes, unicode strings, checksummed addresses, bool edge cases, float rejection, fixed arrays, empty arrays - formatValue boundary: empty arrays, nested arrays, null/undefined, zero bigint, negative bigint, max uint256 - validateHexData: valid hex, empty hex, uppercase, odd-length, missing prefix, invalid chars, spaces - validateArgCount: matching counts, zero counts, mismatch both ways, singular/plural messages - buildAbiItem: simple/complex structures, outputs, empty name - Handler functions (in-process): abiEncodeHandler, calldataHandler, abiDecodeHandler, calldataDecodeHandler with success and error paths - E2E edge cases: zero-arg encode, zero values, string types, excess args, no-name calldata, output type decode, hex validation Coverage: 54.2% → 86.54% (all modules,

Address validation (isValid, equals, ZERO_ADDRESS), Hash module (ZERO, SIZE, fromHex, equals), Selector/Bytes32/Rlp API presence, Hex extended edge cases (large buffers, leading zeros, round-trips) - shared/errors.ts: ChopError structural equality, Effect pipeline patterns (mapError, flatMap, tap, orElse, multiple catchTags), special cause types (number, array, nested errors, newlines, tabs) - cli/errors.ts: CliError structural equality, edge case messages (unicode, long messages, newlines, null cause, nested errors), Effect pipeline patterns (mapError, tapError, orElse) - cli/commands/abi.ts: Handler-level tests for abiEncodeHandler (max uint256, zero address, multiple types, packed encoding, error paths), calldataHandler (approve/balanceOf selectors, excess args, underscored names), abiDecodeHandler (multiple values, round-trips, output type priority, max uint256), calldataDecodeHandler (round-trips for approve/totalSupply/ setBool, result shape, mismatched selector), handler round-trip consistency, abiCommands export, error structural equality Coverage: 86.54% → 89.08% (stmts), 87.5% → 93.75% (funcs) All 312 tests pass.

968d5528eb218962e4c4bc215f8c811610e0c4c7 Mon Sep 17 00:00:00 2001 From: Colin Nielsen <33375223+colinnielsen@users.noreply.github.com> Date: Mon, 9 Feb 2026 19:25:06 -0700 Subject: [PATCH 012/235] =?UTF-8?q?=E2=9C=A8=20feat(cli):=20add=20address?= =?UTF-8?q?=20utility=20commands=20(T1.4)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement 3 address utility CLI commands: - `chop to-check-sum-address ` — EIP-55 checksum conversion - `chop compute-address --deployer --nonce ` — CREATE address - `chop create2 --deployer --salt --init-code ` — CREATE2 Each command supports --json output, exits 1 with descriptive errors on invalid input, and uses Data.TaggedError for error types. Handler logic is separated from CLI wiring for testability (43 tests: unit + E2E).

invoke Command.handler() for crypto and address commands, covering the Command.make blocks that were only exercised through subprocess E2E tests (which don't contribute to v8 in-process coverage). Coverage improvements: - crypto.ts: 61.98% → 88.42% - address.ts: 75.51% → 91.83% - Overall: 82.49% → 86.81% All 733 tests pass. All modules now exceed 80% coverage threshold.

Content-Transfer-Encoding: 8bit Added 41 tests across 4 test files targeting coverage gaps: - evm/wasm.test.ts: stack underflow edge cases (SLOAD, MLOAD, RETURN, BALANCE, MSTORE), MLOAD happy path, custom params (gas, caller, address, value, calldata), executeAsync edge cases - rpc/client.test.ts: malformed response handling (invalid JSON, missing jsonrpc field, null/string/number/array responses, error field) - rpc/server.test.ts: graceful shutdown, empty batch, missing method, invalid jsonrpc, omitted params, notification style, JSON primitives, mixed batch, custom host - cli/commands/rpc.test.ts: callHandler with function signature and decoded output, JSON output for code/storage commands Coverage improvements: - rpc/client.ts: 77.55% → 100% - rpc/handler.ts branch:

tests covering: - evm/conversions: overflow (2^256), NaN hex, max uint256, round-trips - state/account: empty account detection, equality with max values - state/world-state: delete non-existent, snapshot/restore/commit, max storage - procedures/eth: bigintToHex edge cases, max uint256 balances - procedures/types: response constructors with edge-case ids and results - procedures/router: wrong case, unicode, extra spaces in method names - rpc/handler: malformed JSON, wrong jsonrpc version, batch edge cases - blockchain: non-existent blocks, field preservation, max block numbers - handlers/call: value/gas params, contract vs raw bytecode semantics - cli/commands: convert and handler boundary conditions Coverage: 86% stmts, 97% branches, 97% funcs overall. Core modules (blockchain, handlers, procedures, state, shared) at 100%.

ProcedureResult: widen type to include readonly Record[] — removes 4 `as unknown as Record` escape hatches 5. ethGetProof: read actual balance/nonce/codeHash from account state instead of returning hardcoded zeros 6. getLogs: replace lossy `as { number: bigint }` cast with full Block satisfies type in GenesisError catchTag 7.

JSON-RPC procedure router that maps hardhat_* and ganache_* prefixed methods to their anvil_* equivalents. All 23 anvil_* methods are now callable via either prefix. Non-matching aliases fall through with their original method name in error messages.

Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add 7 new test files with 80 tests covering previously untested paths: - getLogs-coverage: address filtering, topic matching, blockHash path, combined filters (18 tests) - eth-txindex: tx-by-block-hash/number-and-index, block tx counts, log/pending filters (10 tests) - wasm-trace: executeWithTrace happy path, STOP, REVERT, SLOAD/BALANCE callbacks (8 tests) - fork-state-coverage: clearState, dumpState/loadState, fallback to 0x0 (7 tests) - traceTransaction-coverage: contract creation, calldata forwarding, HandlerError path (5 tests) - chain-coverage: txHandler, receiptHandler, findBlockHandler, parseBlockId, logsHandler, gasPriceHandler, baseFeeHandler (25 tests) - ens-coverage: resolveNameHandler with mock registry, lookupAddressHandler errors, namehash edge cases (8 tests) Coverage improvements: - getLogs.ts: 46.98% → 87.95% - wasm.ts: 77.02% → 89.18% - traceTransaction.ts: 77.77% → 100% -

App.ts checks callHistory.getState().filterActive before dispatching. This prevents 'q' from quitting and '1'-'8' from switching tabs during filter input. Issue 2: renderList()/renderDetail() now apply filterCallRecords() to viewState.records when a filterQuery is set. handleKey() clamps selectedIndex to filtered record count. Issue 3: Removed dead CallHistoryStore class (never instantiated). Extracted standalone filterCallRecords() pure function. Rewrote tests to cover the new function directly. Issue 4: Exported addCommas() from dashboard-format.ts and re-exported from call-history-format.ts — removed duplicated copy. Issue 5: Added integration-level tests in state.test.ts verifying inputMode passthrough (q/? /1-8/backspace/arbitrary chars all forward as ViewKey). Added end-to-end filter + key routing tests in call-history-view.test.ts.

cb673c89baf4accfb9355b3b84cf985728e3abe0 Mon Sep 17 00:00:00 2001 From: Colin Nielsen <33375223+colinnielsen@users.noreply.github.com> Date: Tue, 24 Feb 2026 10:46:34 -0700 Subject: [PATCH 214/235] =?UTF-8?q?=E2=9C=A8=20feat(tui):=20add=20Settings?= =?UTF-8?q?=20view=20(T4.8)=20with=20editable=20mining=20mode=20and=20gas?= =?UTF-8?q?=20limit?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the Settings view (Tab 7) with form-style key-value layout across 4 sections: Node Configuration, Mining, Gas, and Fork. Mining mode is toggleable (auto/manual/interval cycle) and block gas limit is editable inline. Editable settings take effect immediately on the local devnet. Follows the established 3-layer pattern: - settings-format.ts: pure formatting functions (19 tests) - settings-data.ts: Effect data fetching + mutations (14 tests) - Settings.ts: view component with pure reducer (24 tests) Adds 'space' to VIEW_KEYS for inline toggle support. Wires Settings into App.ts tab 6 with refresh and side-effect handling.
