# Open Arc: What Remains Open After Both Sources

Questions that neither the talk nor the paper resolves.

## From the video

- **[[question-icm-scaling]]** — does single-agent folder navigation handle massive legacy codebases?
- **[[question-voice-security]]** — how is the voice-driven file-system access loop secured against bystander hijack, voice cloning attacks, and command-confirmation gaps?

## From the paper

- **[[question-controlled-comparison]]** — is staged loading measurably better than monolithic prompting? No head-to-head was run.
- **[[question-cross-model]]** — does the five-layer hierarchy hold outside Claude Opus / Sonnet 4.6?
- **[[question-semantic-debugging]]** — can ICM provide automatic traceability (output spans → source snippets) and not just observability?

## Cross-source questions only this synthesis raises

- **Does the voice finale survive when the paper's review-gate discipline is removed?** The talk imagines real-time voice control; the paper's whole epistemics depend on review gates ([[action-review-gates]]). The two need reconciliation. See [[tension-voice-future-vs-paper-non-support]].
- **What is the right boundary between L3 references and L4 working artifacts in long-running workspaces?** As pipelines run repeatedly, today's L4 may become tomorrow's L3 reference. The corpus doesn't address the promotion path.
- **Can the workspace-builder bootstrap a multi-agent ICM?** If ICM can build ICM ([[framework-workspace-builder]]), can it build something the paper excludes — a real-time multi-agent system whose folder substrate is shared at runtime? This is the unstated bridge to the voice future.
- **What is the right unit of governance?** Each stage outputs a plain file ([[concept-observability-side-effect]]), but **provenance** across runs and **policy enforcement** across users are not addressed. Strict glass-box governance (audit trails, traceability) remains unbuilt.
