feat(agent): add online verification and governing-answer citations

Claim-bound online verification observations with URL provenance, exact
answer-basis references for citation-free governing-rule answers, and an
explicit operator identity handoff before source transfer. Bounds resumed
work by learning unit and refreshes pack manifest/contracts.

 Read the pack's [evidence](../../protocols/EVIDENCE.md), [scope](../../protocols/SCOPE.md) and [contribution](../../protocols/CONTRIBUTIONS.md) protocols, then use the [synthesis pipeline](../../pipelines/synthesize.md).
 
+When online verification is enabled, check material changing facts and disputed premises using the shared [online verification protocol](../../protocols/ONLINE_VERIFICATION.md). Keep web observations separate from archived support and preserve source lineage.

 Identify audience, purpose, scope and requested output. Retrieve accepted input revisions and build a dependency inventory. Compare conditions, methods, observations and limitations before composing. Label new interpretation and cite the accepted records it depends on. Preserve contradictory evidence and unknown values.
 
 For comparison requests, use a compact matrix when it makes differences easier to inspect. Choose columns that fit the evidence, such as method, population or sample, conditions, findings and limitations. Cite each cell to the accepted record and source revision that supports it. Mark unavailable values as unknown; do not infer or fill them from memory. Follow the matrix with a short account of agreement, disagreement and evidence gaps when useful.
