server: Substitute rerank placeholder from the original template only. (#30864 )

server: realtime API: send complete after committed audio drains (#30994 )
* server: realtime API: send complete after committed audio drains * server: realtime API: complete a commit at its end row Completion is triggered when the stream runs dry, which is a timing proxy: audio appended while the tail drains leaks into the committed item, a final commit before the drain merges both items, and back to back commits collapse into one. mtmd_audio_stream_flush() records the row count at the end of the flushed audio (mtmd_audio_stream_get_n_rows_flushed), next to the rows produced so far (mtmd_audio_stream_get_n_rows). The slot keeps a FIFO of these end rows and completes each commit once every row up to it is decoded. --------- Co-authored-by: Pascal <admin@serveurperso.com>

@@ -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

+Downstream applications like `llama-server` can then make informed decisions about special token parsing based on the `is_input` flag. In `libcommon`, `common_chat_templates_apply()` returns these parts as `common_chat_params::prompt` (see `common_chat_prompt` in `common/chat.h`).

 **Caveats:**
 - Special tokens dynamically constructed from user input will not function as intended, as they are treated as user input. For example: `'<|' + message['role'] + '|>'`.

+
+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`):
+

+  - **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):

+
+- **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`.

+    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`.
+

+    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`.

+    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:

+    `bit = g` (0..7)
+  - **Scales** (bytes 512..575, 64 bytes):

+    One scale per row applies to all 128 columns (all 4 quarters) of the tile.

+
+- **Q3_K** (512 bytes per tile, `HTP_TENSOR_TILE_SIZE_Q3_K`):

+### `supports_op` Independence from Buffer and Repack State
+
+- `supports_op` (and op-specific checkers such as `supported_mul_mat()`, `supported_get_rows()`) runs during GGML graph scheduling **before** buffers are allocated and before tensor data is populated.
+- **Never check buffer usage or repacking state in `supports_op`**:
+  - `t->buffer` may be NULL or uninitialized.
+  - `t->data` may be NULL.
+  - `buffer->usage` is unknown at scheduling time.
+  - `is_tiled` or `extra->flags & GGML_HEXAGON_TENSOR_TILED` is not set yet.
+- Operator support decisions must depend strictly on static tensor properties: operand types (`t->type`), shapes (`t->ne`), strides (`t->nb`), and operation parameters.
+- Repacking (converting weights to tiled layout) is an internal optimization applied during `set_tensor()` or rt-repack. Non-weight tensors or test harness tensors with the same type remain in flat layout.
+- Therefore, any supported type (such as BF16, F16, quantized types) must be supported both when repacked into tiles and when stored flat in memory.
