The instructionkit→devsync rename never reached the storage layer: `core/mcp/credentials.py`, `utils/paths.py`, `utils/backup.py`, `utils/project.py`, and `ai_tools/mcp_syncer.py` still read/write `.instructionkit/` paths (11 refs). New users get mystery directories under the old product name.
Care required: existing users' credentials live at the old paths — writes should move to `.devsync/` while reads fall back to `.instructionkit/` (with a one-time migration or persistent alias).
Tracked as DEBT-002 in `.codehealth/REGISTER.md`.
