 - The `kinds` array is empty for runtimes with no GSD surface (a hypothetical future runtime with no integration). The `skills` kind is **absent** for runtimes that don't materialize skill directories (Cline; Gemini today). The `commands` kind is **absent** for runtimes that consume only the skills/agents layout (Claude global, Codex, etc.).
 - Per-runtime quirks live in the layout's record fields, not in caller branches:
   - **Hermes**: `{ kind: 'skills', destSubpath: 'skills/gsd', prefix: '' }` — preserves the nested namespace from #2841.
-  - **Cline**: `kinds: [ { kind: 'commands', … } ]` — no skills kind in the array.
+  - **Cline**: `kinds: []` — Cline resolves to zero kinds in Phase 1 (no `commands` kind).
   - **Gemini**: `kinds: [ { kind: 'commands', destSubpath: 'commands/gsd', prefix: 'gsd-' } ]` — no agents, no skills.
 - `applySurface` migrates from `(runtimeConfigDir, commandsDir, agentsDir, manifest, clusterMap)` to `(runtimeConfigDir, layout, manifest, clusterMap)`. Body collapses to `for (const kind of layout.kinds) _syncGsdDir(kind.stage(resolved), path.join(layout.configDir, kind.destSubpath), kind.kind)`.
 - `_findInstallSource` and `_findAgentsSource` in `surface.cjs` are removed. The layout owns source resolution.

 Phase 1 implementation landed on `feat/3663-runtime-artifact-layout-module-phase-1-m`:
 - `get-shit-done/bin/lib/runtime-artifact-layout.cjs` — 15-runtime layout table (grok intentionally excluded), `resolveRuntimeArtifactLayout(runtime, configDir, scope) → Layout`, walk-up `findInstallSourceRoot` helper.
+- Clarification: in this Phase 1 implementation, **Cline resolves to zero kinds** (`kinds: []`), so it carries no `commands` kind in the layout table.
 - `get-shit-done/bin/lib/install-profiles.cjs` — new `stageSkillsForRuntimeAsSkills(srcCommandsDir, resolvedProfile, converter, prefix) → stagedDir` helper.
 - `get-shit-done/bin/lib/surface.cjs` — `applySurface(runtimeConfigDir, layout, manifest, clusterMap)` signature migration; `_findInstallSource` + `_findAgentsSource` deleted; `_syncGsdDir` extended to handle the `skills` kind via directory iteration.
 - Tests: `runtime-artifact-layout-resolve.test.cjs` (16), `runtime-artifact-layout-edge-cases.test.cjs` (10), `runtime-artifact-layout-stage.test.cjs` (5), `install-profiles-stage.test.cjs` (+7 new), `surface-apply.test.cjs` (updated 5 call sites + new skills-kind test).
