[AUD-015] [LOW] Bare src/ import paths across the test tree break compilation under soldeer/submodule consumption #85

Whole-repo audit 2026-08-24 at commit 3e76bab (audit skill 0.35.0). Pass 2 status: ledgered (audit/mutation-test-scans.json, scan of 2026-08-24T08:55:39Z at 35496d8).

test/src/lib/mut/LibConformString.t.sol:8-11

Bare first-party src//test/ import paths in the test tree break compilation whenever the repo is consumed as a git submodule or soldeer dependency (the consumer's own src/ shadows the paths). Complete enumeration — src/ has ZERO bare imports and no script/ dir exists; all 16 occurrences are in 7 test-tree files: test/src/lib/mut/LibConformString.t.sol:8,9,10,11 (src/ x4); test/src/lib/parse/LibParseChar.skipMask.t.sol:7 (src/), :10 (test/); test/src/lib/parse/LibParseChar.isMask.t.sol:7 (src/), :10 (test/); test/src/lib/parse/LibParseDecimal.unsafeDecimalStringToInt.t.sol:8 (src/), :9 (test/), :15 (src/); test/src/lib/parse/LibParseDecimal.unsafeDecimalStringToSignedInt.t.sol:8 (src/), :14 (src/); test/src/lib/parse/LibParseCMask.t.sol:174,175 (src/ x2); test/lib/parse/LibParseDecimalSlow.sol:5 (src/). remappings.txt maps only the three dependencies, so these resolve via ambient project-root resolution only.

Proposed fix

Rewrite all 16 to relative paths. Files at test/src/lib/{mut,parse}/ are 4 levels deep: from "src/X" -> from "../../../../src/X" and from "test/lib/parse/Y" -> from "../../../lib/parse/Y". test/lib/parse/LibParseDecimalSlow.sol:5 is 3 levels deep: from "src/error/ErrParse.sol" -> from "../../../src/error/ErrParse.sol". E.g. LibParseChar.skipMask.t.sol:7 import {LibParseChar} from "../../../../src/lib/parse/LibParseChar.sol"; and :10 import {LibParseCharSlow} from "../../../lib/parse/LibParseCharSlow.sol";. Fix must cover all 16 in one pass — a partial fix leaves the category unresolved.
