- Teach applySurface to build agentCtx (pathPrefix + attribution) and pass it
to kind.stage() for agents kind, mirroring createRuntimeArtifactInstallPlan
(ADR-1235 §1). Surface-path agents now receive path-rewrite + attribution +
converter + normalize, matching install output byte-for-byte.
- Pass skills:'*' sentinel for agents staging when no surface state modifications
exist, so ALL agents are staged (not just those referenced by _calls_agents_).
- Declare converted agents kind in copilot and antigravity capability.json;
add to _DESCRIPTOR_AGENTS_RUNTIMES in bin/install.js.
- Handle copilot .agent.md filename rename in both _copyStaged (install path)
and _syncGsdDir (surface path).
- Ship golden-parity harness (ADR-1235 §0): tests/issue-1575-agent-descriptor-
parity.test.cjs asserts applySurface output is byte-identical to
installRuntimeArtifacts for all 7 descriptor-driven runtimes, plus stale-
cleanup convergence and prune data-loss coverage.
- Update ADR-1235 with cutover progress.
Cline remains deferred (rules-only local branch + local/global complication).
