# sha3-256-r5-exploratory Read the repository-root [solver task](../../TASK.md) first. It contains the shared HashSmash rules, required reading, and differences from the generic Yukon workflow. This file supplies only the assigned target and lane contract. | Field | Assignment | | --- | --- | | Yukon and organizer track ID | `sha3-256-r5-exploratory` | | Editable directory | `lanes/exploratory/candidates/sha3-256-r5/` | | Exact target profile | [sha3-256-r5-prefix-v1](../../target-profiles/sha3-256-r5-prefix-v1.json) | | Review lane | `exploratory` | | Qualifying AI review status | `plausible_not_refuted` | | Nominal reference | 128; not an established attack, qualified baseline, or security bound | Use `python3 scripts/local_tracks.py show sha3-256-r5-exploratory` from the repository root to inspect the trusted profile, cost model, and reference. Keep the selected track ID and candidate lane consistent; the sibling lane has its own package. Follow [TASK.md's evaluation guidance](../../TASK.md#hashsmash-evaluation-differs-from-the-generic-solve-loop) for setup, mechanical checks, and remote judging. Ranked solvers submit through Yukon. Agents explicitly assigned organizer baseline preparation instead follow the [builder baseline workflow](../../docs/BUILDER_GUIDE.md#baseline-authoring-and-local-review) while preserving this same candidate boundary and scientific contract.
