@@ -1,33 +0,0 @@
-You are a coding agent. Here are some very important rules that you must follow:
-
-General:
- Be very precise and concise when writing code, comments, explanations, etc.
- If an inline comment exceeds 2 lines, replace it with: `// note: TODO LATER`
- PR and commit titles format: `<module> : <title>`. Lookup recents for examples
- Don't try to build or run the code unless you are explicitly asked to do so
- Use the `gh` CLI tool when querying PRs, issues, or other GitHub resources
- When [MODEL] is needed, first try to get it from the `PI_MODEL_NAME` env var before asking the user
- Never read the `AGENTS.md` file
-
-Coding:
- When in doubt, always refer to the CONTRIBUTING.md file of the project
- In `test-backend-ops.cpp`, do not mention specific backends (e.g. Metal, CUDA) in comments
- When referencing issues or PRs in comments, use the format:
-  - C/C++ code: `// ref: <url>`
-  - Other (CMake, etc.): `# ref: <url>`
-
-Pull requests (PRs):
- New branch names are prefixed with "gg/"
- Before opening a pull request, ask the user to confirm the description
- Don't explicitly wrap lines in the PR description (each paragraph and bullet is a single line)
- When creating a pull request, look for the repository's PR template and follow it
- For the AI usage disclosure section, write "YES. pi:llama.cpp/[MODEL]"
- If `PI_MODEL_NAME` env var is not set, ask the user to tell you what model was used and write it in place of [MODEL]
- Always create the pull requests in draft mode
- Never reply to review comments or post comments on issues/PRs without explicit permission from the user
-
-Commits:
- On every commit that you make, include a "Assisted-by: pi:llama.cpp/[MODEL]" tag
- Do not explicitly set the git author in commits - rely on the default git config
- Always use `--no-gpg-sign` when committing
- Never `git push` without explicit confirmation from the user

+## Tiled Weight Formats
+
+Weight tensors in the Hexagon backend are repacked from flat row-major GGML layouts into 2D tiles in memory.
+Tiling groups 2D matrix blocks contiguously:
+- Eliminates strided row reads when fetching 2D tiles into VTCM via DMA.
+- Matches native HVX vector width (128 bytes) and HMX systolic array dimensions (32x32).
+- Repacking happens on the host during model load (`set_tensor()`) or via runtime repacking (`rt-repack`).
+Implementation: [`htp-repack.cpp`](../../../ggml/src/ggml-hexagon/htp-repack.cpp).
+
+### Tile Dimensions and Grid Layout
+
+Each tile represents a submatrix of `N_rows = 32` rows and `K_cols` columns:
+- Standard types (`Q4_0`, `Q4_1`, `Q8_0`, `IQ4_NL`, `MXFP4`, and K-quants): `K_cols = 32` (`HTP_TENSOR_TILE_N_COLS = 32`).
+- `Q2_0`: `K_cols = 64` (`HTP_TENSOR_TILE_K_Q2_0 = 64`).
+- `Q1_0`: `K_cols = 128` (`HTP_TENSOR_TILE_K_Q1_0 = 128`).
+
+For a weight matrix of logical shape `[ne0, ne1]` (where `ne0 = K`, `ne1 = N`):
+- `n_k_tiles   = ne0 / K_cols`
+- `n_col_tiles = (ne1 + 31) / 32`
+- Tile index for column-tile `kt` and row-tile `ct`: `tile_idx = ct * n_k_tiles + kt`
+- Byte offset in matrix buffer: `tile_offset = tile_idx * tile_size`
+
+### Block-32 Quantized Formats
+
+Block-32 formats use a tile size of 32 rows x 32 columns (`K_cols = 32`):
+
+- **Q4_0** (576 bytes per tile, `HTP_TENSOR_TILE_SIZE_Q4_0`):
+  - **Quants** (bytes 0..511, 512 bytes):
+    Contains 32 rows x 32 columns of 4-bit quants.
+    Divided into 16 column pairs `cp = 0..15` covering columns `2*cp` and `2*cp + 1`.
+    For each column pair `cp`, 32 bytes are stored consecutively for rows `row = 0..31`:
+    `tile[cp * 32 + row]` holds `(quant[row][2*cp + 1] << 4) | quant[row][2*cp]`.
+    Low nibble holds the even column; high nibble holds the odd column.
+  - **Scales** (bytes 512..575, 64 bytes):
+    32 FP16 values (`ggml_half`), storing scale `d` for each row `row = 0..31`.
+
+- **Q8_0** (1088 bytes per tile, `HTP_TENSOR_TILE_SIZE_Q8_0`):
+  - **Quants** (bytes 0..1023, 1024 bytes):
+    Contains 32 rows x 32 columns of signed 8-bit quants (`int8_t`).
+    Divided into 16 column pairs `cp = 0..15` covering columns `col0 = 2*cp` and `col1 = 2*cp + 1`.
+    For each column pair `cp`, 64 bytes store interleaved column elements for each row `row = 0..31`:
+    `tile[cp * 64 + 2 * row + 0] = quant[row][col0]`
+    `tile[cp * 64 + 2 * row + 1] = quant[row][col1]`
+  - **Scales** (bytes 1024..1087, 64 bytes):
+    32 FP16 values (`ggml_half`), storing scale `d` for each row `row = 0..31`.
+
+- **IQ4_NL** (576 bytes per tile, `HTP_TENSOR_TILE_SIZE_IQ4_NL`):
+  - **Quants** (bytes 0..511, 512 bytes):
+    Same nibble transposition and storage layout as `Q4_0`.
+    Contains 32 rows x 32 columns of non-linear 4-bit indices (values 0..15).
+    Divided into 16 column pairs `cp = 0..15`:
+    `tile[cp * 32 + row]` holds `(quant[row][2*cp + 1] << 4) | quant[row][2*cp]`.
+  - **Scales** (bytes 512..575, 64 bytes):
+    32 FP16 values (`ggml_half`), storing scale `d` for each row `row = 0..31`.
+  - **Dequantization**:
+    In HVX/HMX kernels, each 4-bit index is looked up in the 16-entry non-linear table (`iq4_nl_to_fp16_lut`) to produce an FP16 value, then multiplied by the row scale `d`.
+
+- **MXFP4** (544 bytes per tile, `HTP_TENSOR_TILE_SIZE_MXFP4`):
+  - **Quants** (bytes 0..511, 512 bytes):
+    Same nibble transposition and storage layout as `Q4_0`.
+    Contains 32 rows x 32 columns of 4-bit OCP Microscaling FP4 (E2M1) values.
+    Divided into 16 column pairs `cp = 0..15`:
+    `tile[cp * 32 + row]` holds `(quant[row][2*cp + 1] << 4) | quant[row][2*cp]`.
+  - **Scales** (bytes 512..543, 32 bytes):
+    32 unsigned 8-bit values (`uint8_t`), storing one 8-bit biased exponent (E8M0, bias 127) scale `e` per row `row = 0..31`.
+  - **Dequantization**:
+    Kernel converts E8M0 bias to IEEE FP16 bias via `vh = clamp(e - 112, 0, 30) << 10` to form a power-of-two FP16 scale.
+    Each 4-bit FP4 nibble is unpacked via `mxfp4_to_fp16_lut` and multiplied by this scale.
+
+- **Q4_1** (640 bytes per tile, `HTP_TENSOR_TILE_SIZE_Q4_1`):
+  - **Quants** (bytes 0..511, 512 bytes):
+    Same 4-bit nibble transposition and storage layout as `Q4_0`.
+  - **Scales** (bytes 512..639, 128 bytes):
+    32 pairs of FP16 values (`ggml_half`): `scale[2 * row + 0] = d` (scale) and `scale[2 * row + 1] = m` (min) for each row `row = 0..31`.
+
+### Q1_0 Format (1-Bit Quantization)
+
+`Q1_0` packs 128 columns per tile (`K_cols = 128`, `HTP_TENSOR_TILE_K_Q1_0 = 128`):
+
+- **Tile Layout** (576 bytes per tile, `HTP_TENSOR_TILE_SIZE_Q1_0`):
+  - **Quants** (bytes 0..511, 512 bytes):
+    Contains 32 rows x 128 columns of 1-bit quants (-1 or +1).
+    Divided into 4 quarters (`quarter = 0..3`), where each quarter covers 32 columns in K.
+    Each quarter occupies 128 bytes (1 HVX vector) in `vrmpy` byte order.
+    Within a quarter, columns `kq = 0..31` map into 8 groups `g = kq / 4` (0..7) of 4 consecutive columns:
+    `byte_offset = quarter * 128 + 4 * row + (kq % 4)`
+    `bit = g` (0..7)
+  - **Scales** (bytes 512..575, 64 bytes):
+    32 FP16 values (`ggml_half`), storing scale `d` for each row `row = 0..31`.
+    One scale per row applies to all 128 columns (all 4 quarters) of the tile.
+
+- **HMX Mapping (1-to-4 Tile Expansion)**:
+  - HMX hardware operates strictly on 32x32 FP16 tiles (`HTP_TENSOR_TILE_N_ROWS = 32`, `HTP_TENSOR_TILE_N_COLS = 32`).
+  - During kernel execution, HVX dequantization (`dequantize_tiled_weight_to_fp16_task_q1_0`) expands each 32x128 Q1_0 tile (576 bytes) into 4 contiguous 32x32 FP16 HMX tiles (4 x 2048 bytes = 8192 bytes total) in VTCM.
+  - HMX systolic array processes the 4 resulting 32x32 FP16 tiles over 4 compute steps along K.
+
+### Q2_0 Format (2-Bit Quantization)
+
+`Q2_0` packs 64 columns per tile (`K_cols = 64`, `HTP_TENSOR_TILE_K_Q2_0 = 64`):
+
+- **Tile Layout** (576 bytes per tile, `HTP_TENSOR_TILE_SIZE_Q2_0`):
+  - **Quants** (bytes 0..511, 512 bytes):
+    Contains 32 rows x 64 columns of 2-bit quants (codes 0..3 representing signed values -1..2).
+    Divided into 16 column groups `group = 0..15` of 4 columns each.
+    Stored in `vrmpy` byte order across 4 HVX vectors (vec 0..3):
+    Vector `group >> 2` (0..3) holds `group & 3` at bit offset `2 * (group & 3)`.
+    Byte `4 * row + byte` holds row `row = 0..31` and column byte `0..3`.
+    Vec 0..1 holds the first 32 columns (half 0), vec 2..3 holds the next 32 columns (half 1).
+  - **Scales** (bytes 512..575, 64 bytes):
+    32 FP16 values (`ggml_half`), storing scale `d` for each row `row = 0..31` (at offset `512 + 2 * row`).
+    One scale per row applies to all 64 columns of the tile.
+
+- **HMX Mapping (1-to-2 Tile Expansion)**:
+  - HMX hardware operates strictly on 32x32 FP16 tiles (`HTP_TENSOR_TILE_N_ROWS = 32`, `HTP_TENSOR_TILE_N_COLS = 32`).
+  - During kernel execution, HVX dequantization (`dequantize_tiled_weight_to_fp16_task_q2_0`) expands each 32x64 Q2_0 tile (576 bytes) into 2 contiguous 32x32 FP16 HMX tiles (2 x 2048 bytes = 4096 bytes total) in VTCM.
+  - HMX systolic array processes the 2 resulting 32x32 FP16 tiles over 2 compute steps along K.
+
+- **HVX Vector Dot-Product**:
+  - `tiled_vec_dot_q2_0_32x1` and `tiled_vec_dot_q2_0_32x2` unpack 2-bit quants using `unpack_q3_k_low2`, subtract 1, and accumulate against Q8_0 activation tiles using `Q6_Vw_vrmpyacc_VwVbVb`.
+
+### K-Quants Formats
+
+In GGML, K-quants pack 256 elements per super-block.
+On Hexagon, each 256-element super-block splits along K into 8 tiles of 32 columns (`K_cols = 32`).
+
+Byte ordering: `Q2_K`, `Q3_K`, and `Q6_K` use `vrmpy` byte order within each 128B HVX vector:
+`k = 0..31` is split into 8 groups `g = k/4` of 4 `k` each; byte `4*r + (k%4)` holds row `r`.
+
+- **Q2_K** (336 bytes per tile, `HTP_TENSOR_TILE_SIZE_Q2_K`, lossless tiling with same size as `block_q2_K`):
+  - `bytes   0..255` (vec 0..1): unsigned 2-bit quants; vec `m` holds groups `4m..4m+3` at bit offsets 0, 2, 4, 6.

+
+- **Q3_K** (512 bytes per tile, `HTP_TENSOR_TILE_SIZE_Q3_K`):
+  - `bytes   0..255` (vec 0..1): low 2 bits; vec `m` holds groups `4m..4m+3` at bit offsets 0, 2, 4, 6.
+  - `bytes 256..383` (vec 2): sign mask, bit `g` set when `hmask` is 0 (quant = `low2 - 4`).

The speedup grows with the context length. With `auto`, llama.cpp currently turns Flash Attention off, because the operation runs on a different device than the layer. zDNN runs it when the KV cache is F16 (the default), the model uses no attention sinks, ALiBi or logit softcapping, and there is one KV cache stream (one sequence, or `--kv-unified`). Otherwise it falls back to the CPU.

+### Authentication
+
+A server started with `--api-key` (or any OpenAI-compatible endpoint behind a
+token) needs one here too. `--api-key` is sent as `Authorization: Bearer` on
+every eval request; it falls back to `$LLAMA_API_KEY`, which keeps the secret
+out of your shell history and off the process list.
+
+```bash
+# One key for every server
+python3 llama-eval.py --server http://localhost:8033 --api-key sk-... ...
+
+# From the environment
+export LLAMA_API_KEY=sk-...
+python3 llama-eval.py --server http://localhost:8033 ...
+
+# One key per server, in --server order
+python3 llama-eval.py \
+  --server http://server1:8033,http://server2:8033 \
+  --api-key sk-one,sk-two --threads 16,16 ...
+```
+
+The LLM grader authenticates too. It reuses the key of the server it runs on,
+so `--grader-type llm` without `--grader-server` needs nothing extra; a grader
+on a separate endpoint takes `--grader-api-key`.
+
+Endpoints on an opencode host additionally get an `x-opencode-session` header,
+generated fresh for every task. An agentic episode sends the same id on all of
+its turns, so opencode sees one session per task instead of one per request;
+other servers never see the header.
+
+## Agentic suite
+
+`--dataset agentic` is a different shape from the other code suites. It runs
+**SACB** (Simple Agent Coding Benchmark), hosted at
+[`ilintar/SACB`](https://huggingface.co/datasets/ilintar/SACB) -- 60 tasks over
+three hand-written repositories, in Python and TypeScript. Rather than
+answering one prompt, the model is given a small but real repository, a
+deliberately narrow tool set, and a bug report, and drives its own multi-turn
+conversation until it declares itself finished. It is then graded by running a
+test suite it was never allowed to see.
+
+```bash
+python3 llama-eval.py \
+  --server http://localhost:8033 --model my-model \
+  --dataset agentic --threads 1 --temperature 0
+```
+
+### The tools
+
+| tool | purpose |
+|---|---|
+| `list_files` | enumerate the tree |
+| `read_file` | read, with 1-based line numbers and optional line-range narrowing |
+| `search` | regular-expression search across the repository |
+| `edit_lines` | replace an inclusive line range |
+| `edit_replace` | replace an exact snippet, which must be unique |
+| `write_file` | write a whole file |
+| `lint` | run the language's linter and type checker |
+| `finish` | declare the change complete |
+
+Three constraints are deliberate:
+
+**There is no shell and no way to run the tests.** The only feedback channel is
+`lint`. A syntax or type error can be driven out mechanically; a logic error has
+to be reasoned about. A harness that lets an agent iterate against the test
+suite measures something closer to search than to understanding.
+
+**There are two edit tools**, one line-addressed and one content-addressed.
+Which one a model reaches for, and whether it keeps line numbers straight after
+its own earlier edit, is itself a signal.
+
+**The tests never touch the working tree.** They are held outside it and copied
+into a throwaway copy only after the agent has stopped, so they can be neither
+read nor edited. Every tool path is resolved and confinement-checked against the
+repository root, so a symlink planted inside the tree cannot reach outside it.
+
+### Scoring
+
+A task is **resolved** when every test that was failing now passes *and* nothing
+that was already passing broke. Both sets are derived by running the tests twice
+when the corpus is built -- once against the defective tree and once against the
+reference fix -- never hand-written, so a task whose defect no test exercises is
+rejected rather than shipped.
+
+Because many tasks contain several independent defects, the fraction of target
+tests passed is reported alongside, which separates "fixed two of the three
+faults" from "changed nothing". Process metrics are reported too: turns, tool
+calls, rejected calls, edits, and the peak conversation size.
+
+### Dependencies
+
+Nothing here is installed unless you select this suite, and then only for the
+language you actually run. `--agentic-lang python` provisions ruff and mypy;
+`--agentic-lang typescript` provisions the TypeScript compiler and uses node's
+own test runner. Neither touches the other, and no other suite touches either.
+
+### Useful flags
+
+| flag | meaning |
+|---|---|
+| `--agentic-lang` | restrict to one language, and provision only its toolchain |
+| `--agentic-max-turns` | give up after this many assistant turns (default 50) |
+| `--agentic-max-tokens` | cap generation per turn (default: no cap); bounds a model that falls into a repetition loop, but also cuts reasoning off mid-thought. Truncated turns are counted as `truncated_turns` |
+| `--agentic-context-limit` | abandon an episode once its context exceeds this many tokens |
+| `--agentic-transcripts DIR` | save each episode's full message history to `DIR/<task_id>.json`, plus a `DIR/<task_id>.html` showing every reasoning block, reply, tool call and tool result; the main report links to it |
+
+
+## Code suites (HumanEval, ClassEval)
+
+`--dataset humaneval` runs the 164 OpenAI HumanEval problems; `--dataset
+classeval` runs the 100 ClassEval class-generation tasks. Unlike the other
+suites these are not graded by matching text: the model's reply is parsed for a
+```` ```python ```` block, that code is combined with the task's own unit tests,
+and the result is **executed**.
+
+ClassEval asks for a whole class rather than one function, so it is scored the
+way upstream does - **class level** (every one of the task's tests passes, which
+is what feeds pass@k) and **method level** (what fraction of all 2196 test
+methods passed). The second number separates "generated nothing usable" from
+"got most of the class right", and both are printed at the end of a run.
+
+Give it more room to generate than HumanEval - a class with ten methods does not
+fit in a short budget:
+
+```bash
+python3 llama-eval.py \
+  --server http://localhost:8033 --model my-model \
+  --dataset classeval --threads 8 --n_predict 4096 --temperature 0
+```
+
+```bash
+# pass@1, greedy
+python3 llama-eval.py \
+  --server http://localhost:8033 --model my-model \
+  --dataset humaneval --threads 8 --n_predict 1024 --temperature 0
+
+# pass@10 -- each extra multiple of 164 is another sample per problem
+python3 llama-eval.py \
+  --server http://localhost:8033 --model my-model \
+  --dataset humaneval --n_cases 1640 --temperature 0.8 --top-p 0.95
+```
+
+`--grader-type exec` is the default for code suites, so neither it nor
+`--dataset-source` normally needs to be passed.
+
+### Execution sandbox - no Docker required
+
+Generated code is untrusted, but these suites need far less than a container to
+run safely. **The package set is derived from the dataset's own imports at
+startup**, not hardcoded and not taken from the upstream `requirements.txt` -
+which for ClassEval lists `torch`, `openai` and `transformers` that its *tests*
+never touch. So each suite installs exactly what it needs:
+
+| suite | third-party packages |
+|---|---|
+| HumanEval | **none** - every problem imports only stdlib (`typing, math, random, copy, string, collections, hashlib, re`) |
+| ClassEval | 13: `beautifulsoup4, gensim, lxml, netifaces, nltk, numpy, openpyxl, pandas, pillow, pypdf2, python-docx, reportlab, scipy` |
+
+Two of ClassEval's are *declared* rather than derived, because no import
+statement mentions them: `lxml` is selected by string
+(`BeautifulSoup(html, 'lxml')`, ClassEval_44 - without it that task silently
+drops from 23/23 to 7/23), and `scipy` is a hard gensim requirement. Note also
+that `PyPDF2` must **not** be modernised to `pypdf`: ClassEval_69's test imports
+`PdfFileReader`, a name pypdf removed.
+
+The venv is cached under `~/.cache/llama-eval/` (override with
+`LLAMA_EVAL_CACHE`) and rebuilt only when the package set, interpreter version
+or provisioning steps change; force one with `--rebuild-sandbox`. `uv` is used
+when available, which makes even the ClassEval venv build in seconds.
+
+**Interpreter selection.** A suite can prefer a different Python than the one
+running the tool, and declares it: ClassEval asks for 3.13, because gensim
+publishes no wheel past cp313 and its generated C no longer compiles on 3.14
+(it still uses `PyLongObject.ob_digit`). That interpreter is found automatically,
+including via `uv python`; `--sandbox-python` overrides it.
+
+3.14 is fully supported anyway. ClassEval uses exactly two gensim APIs
+(`utils.decode_htmlentities`, `matutils.unitvec`), both pure Python upstream, so
+on 3.14+ the suite drops gensim from the install set and provisions a small shim
+instead. Both paths score **100/100**.
+
+**Offline provisioning.** A suite that would otherwise fetch data at test time
+declares a provisioning step that runs once at venv build time, while the
+network is still up. ClassEval uses this to pre-seed exactly three nltk corpora
+(`punkt_tab`, `averaged_perceptron_tagger_eng`, `wordnet`, ~33 MB), so the tests
+themselves run with no network at all. Those are the *current* names - the
+dataset asks for `punkt` and `averaged_perceptron_tagger`, which nltk has since
+renamed, and seeding the legacy names too is not harmless: with a network
+available nltk considers them satisfied and re-fetches the modern ones anyway.
+The corpora are written *inside* the venv, not `~/nltk_data`, because `$HOME` is
+a tmpfs under the strongest isolation tier.
+
+Each candidate program runs in a throwaway directory as its own process group,
+under the strongest isolation the host offers:
+
+| tier | requires | isolates |
+|---|---|---|
+| `bwrap` | bubblewrap installed | read-only root, tmpfs `/tmp` and `$HOME`, **no network** |
+| `unshare` | `unshare --map-current-user` | **no network** |
+| `unshare-root` | any `unshare -r` | no network, but **runs as uid 0** - see below |
+| `rlimit` | always available | cpu/memory/file-size/process caps only |
+
+**Candidate code must not run as root**, which is why `unshare -r` is a
+last-resort tier that prints a warning. Root bypasses file permission bits, so a
+test asserting that writing to a `chmod 0444` file *fails* instead sees it
+succeed - ClassEval_50 scores 14/16 under uid 0 and 16/16 under uid 1000, with
+nothing in the output to suggest the sandbox caused it. Install bubblewrap.
+
+All tiers additionally cap CPU time, address space (4 GiB), file size and core
+dumps, and kill the whole process group on timeout (`--exec-timeout`, default
+15 s - raise it for ClassEval, whose tests do real work). Writes to the
+throwaway working directory are allowed, which is all the file-handling tasks in
+ClassEval need.
+
+Note that the weakest tier does not contain filesystem access. If you are
+scoring output from a model you do not trust, check the tier printed at startup.
+
+### Reproducibility
+
+Several tasks draw their test inputs from the *global, unseeded* RNG, so a
+verdict is not reproducible run to run - which adds noise exactly when you are
+comparing two models or two quantisations. `--exec-seed` (default `0`) seeds the
+RNG before each test; pass `--exec-seed -1` for the stock upstream behaviour.
+This does not change what the model is asked to compute.
+
+It matters more than it sounds. HumanEval/38, /50 and /53 are affected, and
+ClassEval_58 (duplicate mine placement) fails about 30% of the time on its own
+*reference* solution - measured here at 21/30 passes unseeded versus **30/30
+seeded**.
+
+### Dataset fidelity
+
+The canonical dataset runs **unmodified on current Python** - all 164 reference
+solutions pass on CPython 3.14 with no patches, so no forked or re-hosted copy
+is needed. `--dataset-source` accepts a local `.jsonl` or a HuggingFace repo id
+if you do want to point at a modified copy.
+
+HumanEval does contain a handful of long-standing defects where the *prompt*
+contradicts the graded test (notably HumanEval/47, /116 and /148). Those
+penalise a model that reads the docstring carefully, but correcting them makes
+the benchmark marginally easier and the resulting scores no longer comparable
+with published HumanEval numbers, so nothing is patched by default.
+
+ClassEval is different: the upstream data has defects that cap the achievable
+score below 100% for reasons unrelated to the model, so `--dataset classeval`
+defaults to a **patched fork**,
+[`ilintar/ClassEval`](https://huggingface.co/datasets/ilintar/ClassEval).
+Six edits over five tasks lift the reference solutions from 96/100 classes and
+2182/2196 test methods to **100/100 and 2196/2196**. Three repair tests nothing
+could pass:
+
+- **ClassEval_17** was a time bomb - a hard-coded 2024 date checked against
+  `datetime.now()`, unpassable since January 2024.
+- **ClassEval_48** asserted `get_hostname('0.0.0.0') == 'LAPTOP-2CS86KUM'`, the
+  dataset author's own machine name.
+- **ClassEval_31** compared floats with `assertEqual`, failing on a 4-ULP numpy
+  difference.
+
+The other three fix only the *reference* solutions (NumPy 2.0 removals in
+ClassEval_51, a 30%-flaky mine generator in ClassEval_58) and cannot affect a
+model's score. No `skeleton` was touched, so what the model is asked to write is
+byte-identical to upstream. Pass `--dataset-source FudanSELab/ClassEval` for the
+unpatched original.

+"""Multi-turn agentic coding eval: tools over a real working tree.
+
+The existing code suites are single-shot -- one prompt, one reply, execute,
+grade. This one is not. The model is given a small but real repository and a
+deliberately narrow tool set, and has to find its way to the defect before it
+can fix it. That shape is what puts a run in the tens-of-thousands-of-tokens
+range without any artificial padding: the context grows because the model
+chose to read things.
+
+Three deliberate constraints:
+
+* No shell, and no way to run the tests. The only feedback channel is `lint`.
+  A syntax or type error can be driven out mechanically; a logic error has to
+  be reasoned about. Suites that let an agent iterate against the test suite
+  measure something closer to search than to understanding.
+* Two edit tools, one line-addressed and one content-addressed. Which one a
+  model reaches for, and whether it keeps line numbers straight after its own
+  earlier edit, is itself a signal.
+* Tests never touch the working tree. They are held outside it and copied in
+  after the agent has stopped, so they can be neither read nor edited.
+
+Everything here is imported lazily by llama-eval.py, and every dependency it
+needs is scoped to the language actually under test, so none of it is
+installed for anyone running the other suites.

+
+How this session works:
+- You are working autonomously. There is no human watching; nobody will answer
+  questions, approve a plan, or read progress reports.
+- Every reply you send must contain at least one tool call until the task is
+  done. A reply that contains only text does nothing: no work happens and the
+  turn is wasted. Do not stop to describe what you are about to do; do it.
+- The session ends only when you call `finish`. Call it once the change is
+  made, and not before. Only the files as you leave them are evaluated.
+
+Important constraints:
+- You cannot run the code, the tests, or any shell command. The only feedback
+  available is the `lint` tool, which reports syntax and type problems.
+- The repository already has a test suite that will be run against your work
+  after you finish, but you cannot see it or run it. Do not create test files.
+- Read enough of the code to understand it before editing. A change that only
+  makes the symptom go away will usually fail the tests.
+- Make the smallest correct change. Do not reformat or refactor unrelated code.
+
+Keep calling tools until the change is complete, then call `finish`."""
