The investigation page stops drawing lanes. The provenance canvas is issue → incident → investigation → verdict → actions, with a process-only ghost where the verdict will land while the pass runs; the verdict card's running, failed and inconclusive shapes describe one agent; the Hypotheses tab, the lens fan, the lens-lane ledger and the "lenses in flight" hub stats go. What the run considered and dropped is the report's own `ruledOut`, which the inconclusive card already renders. The detail page syncs one Electric shape now — the investigation row — rather than the row plus its lanes. The wire still carries empty `lens_runs`, a null `validator` and the `fanout` bookkeeping for rows written before the rework; the next change drops them.
📝 WalkthroughWalkthroughThe change removes lens-run fan-out from investigation data, provenance graphs, loading placeholders, verdict cards, navigation, and triage displays. Investigations now use a single model-pass flow with direct evidence gathering and verdict handling. ChangesSingle-agent investigation flow

Update the stale mapper assertion.
rowsToInvestigation now always emits an empty lens_runs array. The existing mapper test still calls toMatchObject on investigation?.lens_runs[0], which is now undefined. This makes the relevant Vitest suite fail. Replace that assertion with checks for lens_runs: [] and validator: null.
