📄 Description

Summary

Fix cross-platform path separator handling in macOS and Linux Hopper launcher candidate discovery.

Problem and expected behavior

src/application/MacHopperPaths.ts and src/application/LinuxHopper.ts imported ambient join from "node:path". On non-POSIX/Windows hosts, join emitted Windows backslashes (\) for macOS bundle structures and Linux directories (e.g. \Applications\Hopper Disassembler.app\...), breaking candidate matching.

Expected behavior: macOS and Linux application paths represent Unix file system targets and must always use canonical POSIX forward slashes (/), regardless of the operating system hosting REA.

Change and scope

Replaced ambient join with posix.join in src/application/MacHopperPaths.ts and src/application/LinuxHopper.ts.
Normalized user home directory separators (toPosix) before path joining.
Updated src/application/MacHopperPaths.test.ts to assert against normalized POSIX paths.

Follow the contribution scope: not applicable (routine bug fix within existing provider discovery boundaries).

Contract and boundary impact

Semantic owner and earliest changed stage: src/application/MacHopperPaths.ts & src/application/LinuxHopper.ts (provider discovery).
Contribution scope fit and linked maintainer decision: Not applicable (routine bug fix).
CLI and MCP/tool-catalog contract: No contract changes.
Provider, bridge, target-format, or platform compatibility: Restores cross-platform compatibility for Hopper discovery diagnostics when executed on Windows/non-POSIX hosts.
Evidence, artifact, provenance, or reconstruction contract: No changes.
Target selection, authority, upstream behavior, and cleanup details: Not applicable.
Generated metadata impact: None.

Expected effects:

Read existing files or captured data.
Launch or attach to a process.
Inject instrumentation or run scripts/code.
Change process memory, registers, files, or configuration.
Contact network services.
Recover protected code or work around protections.
Documentation or usability only; no target interaction.
Not sure yet; investigation or maintainer guidance needed.

Evidence and regression coverage

Tests added or updated: src/application/MacHopperPaths.test.ts (updated expectation assertion for cross-platform candidate verification).
Base reproduction or other evidence: On Windows, npm run test:local -- src/application/MacHopperPaths.test.ts previously failed 2 tests with AssertionError: expected ['/Applications/...'] to deeply equal ['\\Applications\\...']. npm run test:local -- src/application/Doctor.test.ts previously failed checks the canonical user install after the system launcher with AssertionError: expected undefined to be ....
User-visible CLI/MCP output: Not applicable.
Remaining proof gaps: None.

Validation performed

npm run test:local -- src/application/MacHopperPaths.test.ts — 3/3 tests passed.
npm run test:local -- src/application/Doctor.test.ts — 32/32 tests passed.
npm run check:fast — TypeScript typecheck and Oxlint passed with 0 errors.
npm run format:check — All 4,025 files verified clean.

Compatibility, safety, and release

Breaking changes or migration steps: None.
Real Hopper/Ghidra, browser, or OS coverage: Validated on Windows 11 x64; unit tests run across Node.js 22.19.0.
Package or release metadata impact: None.
Security, privacy, process, or containment review: Safe; no permission, network, or process execution changes.
