Wire the VGR helpers into production routing. derive_capabilities and select_branch have no non-test callers. Production Algorithm implementations and server routing code do not reference the private vgr module. Therefore, the Verification-Gated Routing code has no runtime routing effect. Add the production delegation or integration boundary that invokes both helpers.

Add comments for non-obvious helpers and behavior tests.
The Rust guidelines require concise comments for private helpers with non-obvious behavior and tests that encode important behavior. Add comments for:
content_text: explain recursive extraction and fail-closed handling of unsupported content.observed_code_activityandobserved_tool_activity: explain the activity markers that each detector recognizes.- The four tests: document their branch-selection, fail-closed, capability-source, and redaction/input-boundary invariants.
This requirement does not apply to the pub(super) RequestView declaration.

Enforce the size limit before redaction.
request_view redacts each input before it builds transcript, then checks only the redacted transcript length. Therefore, a request or attempt larger than 24,000 characters can pass when a redaction pattern replaces most of its text. latest_user preserves the original value in task_text, and derive_capabilities stores the original attempt, so Capabilities can retain the oversized source value.
The existing test covers only an oversized unredacted "x" value. Add a regression test for an oversized value that matches a redaction pattern, and enforce the limit on source characters before redaction and cloning.
