+# COIN v2026-07
+
+**COde-understanding through INput-space mapping** — a benchmark that
+measures an agent's ability to translate a natural-language reachability
+goal ("reach line X of file Y") into an input that exercises that line at
+runtime.
+
+This release pins **70 verified targets** drawn from
+7 OSS-Fuzz projects. Every target is paired
+with a runtime docker image whose digest is captured below — a snapshot is
+content-addressed end-to-end, so reruns six months from now hit the same
+binaries.
+
+## Quick start
+
+```python
+from datasets import load_dataset
+
+ds = load_dataset(
+    "COIN-Bench/coin",
+    revision="v2026-07",
+    split="codeql_only",
+)
+print(ds[0]["target_id"], ds[0]["runtime_image"])
+```
+
+To run the full evaluation pipeline against this snapshot:
+
+```bash
+pip install coin-bench
+coin evaluate \
+  --dataset COIN-Bench/coin \
+  --revision v2026-07 \
+  --split codeql_only \
+  --output-dir results/
+```
+
+## Splits
+
+Splits are first-match-wins over the 6-bit signal cube
+``(G, S, N, F, L, C)`` — GCS-covered, seed-reachable, fuzzer-reachable
+(libfuzzer-noseed), baseline-reachable (libfuzzer), LLM-baseline-reachable,
+CodeQL-statically-reachable.
+
+| Split | Cell | Rows |
+|---|---|---|| `gcs_reachable` | `G and not (F or L)` | 35 || `codeql_only` | `C and not (G or F or L)` | 35 |
+## Runtime images
+
+One per project. Digest-pinned for reproducibility — the dataset rows
+reference these digests directly.
+

+
+| Column | Type | Meaning |
+|---|---|---|
+| `target_id` | str | `<project>:<harness>:<file>:<line_start>[-<line_end>]` |
+| `coin_version` | str | snapshot tag (e.g. `v2026-07`) |
+| `coin_commit` | str | git SHA of the COIN repo at release time |
+| `oss_fuzz_commit` | str | OSS-Fuzz commit pinned for this snapshot |
+| `coverage_date` | str | GCS HTML coverage report date |
+| `project` | str | OSS-Fuzz project name |
+| `harness` | str | primary reaching harness binary |
+| `harness_binaries` | str (JSON list) | harness binary basenames in the project |
+| `language` | str | `c` / `c++` / `rust` / `python` / `jvm` |
+| `file` | str | canonical `/src/<project>/<rel>` path |
+| `line_start`, `line_end`, `line_count` | int | target line range |
+| `function` | str | enclosing function (empty if not extracted) |
+| `source_snippet` | str | ±100 lines around the target |
+| `src_commits` | str (JSON list) | `[{path, rev, url}]` for git-cloning |
+| `gcs_covered` | bool | `G` signal — line in the GCS coverage report |
+| `baseline_reachable` | str (JSON list or "null") | `F` — stage5 libfuzzer baseline (with seed if present) |
+| `agent_baseline_reachable` | str (JSON list or "null") | `L` — LLM seed-gen baseline |
+| `codeql_reachable` | str (JSON list or "null") | `C` — CodeQL static reachability |

+| `target_text` | str | one-line human description |
+| `prompt_preview` | str | TASK.md preview that stage7 sends to the agent |
+| `runtime_image` | str | `<image>@sha256:...` — the image to spin up |
+| `runtime_digest` | str | the digest alone, for content addressing |
+| `runtime_normal_path` | str | path inside the image: harness binaries (`/out/normal`) |
+| `runtime_coverage_path` | str | path inside the image: coverage build (`/out/coverage`) |
+| `runtime_source_path` | str | path inside the image: source repos (`/src`) |
+| `split` | str | denormalized split name (matches the row's file) |
+
+## What's automated, what's manual
+
+| Step | Type |
+|---|---|
+| OSS-Fuzz coverage HTML download | manual (operator) |
+| Per-project build (normal + coverage) | manual (operator) |
+| Baseline fuzzing (stages 5 + 5b) | manual (operator) |
+| Target selection (stage 6) | manual (operator) |
+| Snapshot release (`coin release`) | manual command, fully reproducible |
+| Evaluation against this snapshot | **fully automated** for downstream users |
+
+The selection pipeline is operator-driven; once a snapshot is published,
+running it against your agent is one command.
