…ml-org#31153) * common, grammar: add recursive depth limit, make it a requirement * catch more recursive functions * common : tidy up peg parser changes * grammar : reject candidates in a loop, without a depth limit The depth limit in llama_grammar_reject_candidates_for_stack counted the code points of a vocab token, so any token of 256 chars or more was always rejected under a grammar, such as the 512-space token of GLM-4.7-Flash or the long space tokens of Laguna-S-2.1. The rejection now walks the code points with its own stack of levels instead of recursing: there is no limit and no stack risk, whatever the length of a token from the GGUF, and the masks match master. * grammar : track rejected candidates as indices into the input At a given code point a candidate only differs from its input by the position of its code point pointer, so the levels now carry indices into the input candidates instead of copies. The first level needs no special case and the rejects map back to the input directly. Grammar sampling gets faster than master on GLM-4.7, Laguna, Qwen3.6 and gemma-4 with the json, list and spaces grammars, same masks. * nit : shorten the comment of llama_grammar_reject_step * common : add depth_guard for schema walks * grammar : move GRAMMAR_RECURSIVE_LIMIT into the .cpp * common : reduce recursion limit for peg parser * improve --------- Co-authored-by: Alde Rojas <hello@alde.dev> Co-authored-by: Pascal <admin@serveurperso.com>

* ui : let the expanded sidebar be resized by dragging its edge Bring back the desktop sidebar resize handle that was dropped with the shadcn sidebar primitive. The width is clamped between 18rem and 32rem, persists across reloads, and resets on a double-click of the handle. The tab bar follows the same width so a wider sidebar never covers it. Assisted by: Claude (Opus 5.5 Medium) * ui : rubber-band the sidebar edge past its bounds and drag it shut Past the max width the edge resists harder the further it is pulled, and the same happens below the min width until the pull passes 9rem, where it snaps to the pointer and letting go hides the sidebar. A release outside the bounds springs the width back to the nearest one. Assisted by: Claude (Opus 5.5 Medium) * ui : show the sidebar edge strip faintly on hover and solid while dragging The strip is clipped to the sidebar's rounded corners through its own overlay, so the sidebar itself is never clipped. Assisted by: Claude (Opus 5.5 Medium) * ui : remember whether the desktop sidebar is open across reloads A phone opens the sidebar as an overlay, so it always starts closed there and its toggling never overwrites the desktop preference. Assisted by: Claude (Opus 5.5 Medium) * ui : fade the sidebar labels and conversation list with its width The fade follows the live width, so it tracks both the toggle's width transition and a drag below the minimum width. Assisted by: Claude (Opus 5.5 Medium) * ui : persist the sidebar width on release and clamp a restored one A drag now updates only the live width and writes it to localStorage once when released. A width restored from localStorage is clamped to the current bounds, so a value saved under older bounds does not stick. Assisted-by: Claude (Opus 5.5 Medium)
* ui : land opened conversations at their bottom before the first paint Pin the page to its bottom with a ResizeObserver until it stops resizing or the reader interacts, and mount the last rows eagerly so the landing frame shows real content. Assisted by: Claude (Opus 5.5 Medium) * ui : make conversation tabs browser-style A plain navigation shows the chat in the current tab instead of adding one, and the new-chat tab turns into the conversation it starts. New tabs come only from explicit actions: the + button, Cmd/Ctrl-click or middle-click on a sidebar chat, and its Open in new tab menu item, which open in the background. Closing a tab moves to its neighbour among the tabs the view shows. Assisted by: Claude (Opus 5.5 Medium) * ui : share the tab surface and tab bar fade styles Move the tab item surface (shape, resting and active looks) to TAB_SURFACE_* class constants and the fade under the tab bar to a global chat-top-fade class, so other elements can match the tabs. Assisted by: Claude (Opus 5.5 Medium) * ui : fit the chat column below the tab bar The tab bar reported 1.25rem of its height while it takes 3.3125rem (pt-3.25 + h-10), so a short conversation still left a few pixels to scroll. Use the bar's full height and drop the extra 1rem from the column's minimum height, so it fills the viewport exactly; the centered new-chat form moves up by the same 1rem to keep its place. Assisted by: Claude (Opus 5.5 Medium) * ui : stop the page from bouncing past its ends Elastic overscroll on the root scroller dragged the sticky and fixed bars (tab bar, chat form) along at the top and bottom of a chat, and they jumped back on release. Set overscroll-behavior: none on html and body. Assisted by: Claude (Opus 5.5 Medium) * ui : stop scrolled dialogs from bouncing past their ends Dialogs scroll on their own (the settings panel, the search results), so the page rule did not reach them and their sticky navigation still jumped on overscroll. Turn off overscroll on dialog panels and on the scroll containers inside them. Only scroll containers: Firefox counts an overflow-hidden box such as truncated text as one, and `none` there kept the wheel from scrolling the list around it. Assisted by: Claude (Opus 5.5 Medium) * ui : fit a first exchange opened by the working directory row The last answer's minimum height leaves room for the last question only, so the synthetic row that a new chat starts with (Set working directory to ...) made a short first exchange overflow by that row. When everything above the last question is synthetic, count those rows as part of it. Assisted by: Claude (Opus 5.5 Medium) * ui : keep following a streaming response until the reader scrolls up Auto-scroll stopped whenever the page moved up, including moves the reader did not make: scroll anchoring and blocks re-rendering shorter while a response streams. Only the reader's wheel, touch, scroll keys or scrollbar drag now count as scrolling up. The send scroll also looked up the new user bubble by position, which picked an older message when the answer row had not rendered yet. Assisted by: Claude (Opus 5.5 Medium) * ui : fade the chat form between its centered and bottom positions The form no longer slides across the column between the new-chat center and the bottom. It fades out drifting toward where it goes and fades back in where it lands, quicker when opening a chat than when going back to a new one. Its wrapper keeps the same height in both positions, so the messages never shift while it moves. The new-chat greeting fades in as the form settles, also on a refresh or a first visit. Reduced motion keeps only the fades. Assisted by: Claude (Opus 5.5 Medium)

* tests: pin model resolution on real repo listings Extend test-model-resolution with 63 repo listings captured verbatim from the HF API, chosen to cover every file naming pattern found across 1237 GGUF repos of the major publishers and pruned to whole quant groups. Each repo pins its resolved plans and its cache listing. The expectations follow what each file really is per its GGUF header, not what the current resolver picks, so a mismatch is a resolution bug. Mismatches are collected and reported together before the test fails. * tests: leave the listing unchecked on paths the filesystem refuses Some real split names (DevQuasar's Model.Q2_K.gguf-00001-of-00012.gguf under a quant folder) exceed MAX_PATH once materialized in the temporary cache on Windows, so the listing of such a repo is skipped with a note while its plans stay checked. * tests: pin real listings to master on GGUF convention names only Replace the real repo table with 171 HF listings whose file names follow the GGUF naming convention (lowercase sidecar prefix, - delimited components, quant last), one per layout pattern found across 1174 GGUF repos and pruned to whole quant groups. Repos outside the convention are dropped. Each repo pins the plans and the cache listing master gives today, so the test is a pure harness: any change in resolution shows up here, and mismatches are reported together.
* sycl: add set_tensor_2d for faster tensor-split loading Pack host rows into chunks of up to 64 MiB when destination rows are contiguous, avoiding a separate upload call for each row. Keep the existing per-row copy path for non-contiguous destinations. On two Arc Pro B70s with gpt-oss-120b UD-Q4_K_XL, total llama-perplexity runtime drops from 263-268 s to 114-115 s. A full-load readback check verified 26,784,256 rows with no mismatches. * sycl: batch 2D tensor uploads through shared staging slots Implement set_tensor_2d to speed up tensor-split model loading by packing rows into the existing pinned staging slots and uploading each batch with a single device copy. Share staging initialization with set_tensor and wait only when reusing a slot, allowing CPU packing and device copies to overlap. Fall back to per-row uploads for noncontiguous device rows, oversized rows, or unavailable staging. --------- Co-authored-by: Jon Staples <250234834+Captain-Tripps@users.noreply.github.com>

…1179) Every dst row comes from src0 or src1, or for dim 0 from the row of src0 followed by the row of src1, so a single kernel covers every type: a dense source row is one memcpy, quantized types included, and a strided source is copied element by element with the element size known at compile time. Rows are split across threads instead of i2 alone, which is often 1, and are copied in tiles of 32: for a transposed source the elements are walked in the outer loop, so the rows of a tile read neighboring addresses instead of jumping a full row stride per element. Add transposed b cases to test_concat, the layout of the delta-net conv input, and a perf case for it.

…#31176) * ui: open model details in a global drawer without leaving the page The model info actions in the selector used to navigate to the models page to open its details pane, and a phone opened a separate dialog instead. The drawer now lives outside the models table, driven by uiStore, so the info icon opens it over whatever page is showing. The models dropdown and the phone picker stay open under the drawer's backdrop, and keep focus while the drawer opens and closes, so the trigger's tooltip no longer pops over the drawer. Assisted-by: Claude (Opus 5.5 Medium) * ui: let the model details drawer reopen after a drag to dismiss Dragging the drawer down wrote vaul's own open state, which the one-way open prop then kept closed, so the info action could not open it again until a refresh.

* ui: add conversation compaction Add a compaction action that asks the model to summarize the conversation so far and stores the summary in a new compaction node appended to the branch. Later requests slice the branch at the last compaction node, keeping the system prefix and continuing from the summary instead of the full history, which frees up context while the complete history stays visible and navigable in the UI. The slice is applied once at the request funnel, covering the plain send, the agentic flow and the KV cache pre-encode, plus the continue path that bypasses it. The summary request is a one-shot outside the SSE replay machinery, streamed live into the node with a full rollback on abort, error or empty result. The action is exposed as a /compact slash command and a Compact button in the context gauge popup, with an overridable summarization prompt in the settings. * ui: pre-fill KV cache and refresh context gauge after compaction Once the summary is stored, pre-encode the compacted branch and stamp the returned prompt timings on the compaction node: re-encoding the reduced prefix is part of the compaction itself, so the server KV cache and the context gauge reflect the summary right away. The summary stream is registered under a prefixed identity (compact::convId), so the visibility kick and byte-offset resume protect it through tab switches while the reload probe never reattaches it as a chat turn. The stamped node becomes the shared context truth for the gauge and the processing state restore, and the stale live state that kept the gauge full is cleared. * chore: format * ui: allow a dedicated model for conversation compaction An opt-in setting reveals a model selector whose options come from the live router model list. The chosen model writes the summary and is loaded on demand when it is not resident, while the default path keeps resolving to the conversation's own model. * ui: align the compaction model field with project conventions * ui: fix the model option helpers import path The compaction model selector pulls filterModelOptions and groupModelOptions from the models component folder, where they no longer live, so the build fails to resolve the module. Point the import at the navigation folder, which now owns them. Missed during the rebase: the helpers moved in a commit that does not touch any compaction file, so nothing conflicted. * ui: import the model option helpers from models/utils * ui: follow the moved models selector in the compaction model field The models manager moved ModelsSelectorList under ModelsSelector and the model option helpers to /utils, where groupModelOptions takes the options alone. Drop the stale copy the rebase kept and read the helpers from their new home. * ui: drop the dedicated compaction model A summary written by another model loses the prefix the conversation model cached, so the whole history is prefilled again, and the model then resumes from text it did not write. The conversation model always writes its own summary. * ui: keep the last steps of a compacted conversation A compaction now folds the steps the model reads but the last ones, a step being a user message or an assistant message with its tool results, and stores how many it kept on the compaction node. The model then reads the system prefix, the summary, the kept steps and what follows. The summary request is the request the chat sends, with its options, tools and message shaping, cut before the preserved steps: the server reuses the prefix it cached and only the instruction is new. The number of preserved steps is a setting, 10 by default. * ui: run every compaction summary through one path Three callers needed the same thing - the automatic pre-encode pass, the action in the context gauge, and re-running a summary from the block - and each of them had grown its own copy of the request, the streaming and the storing. There is one path now: a summarization owns a node, streams into it, and reports itself through a ledger the rest of the app reads (`isCompacting`, which node belongs to which conversation). Re-running a summary is the same call on an existing node, so the two entry points cannot drift apart again. * ui: give the compaction row its own summary UI The summary was a line of text in a tool-call-shaped collapsible, which is how a compaction reads as a side note rather than as the thing the rest of the conversation now stands on. The row is its own block: a divider that names the boundary, and the summary inside it with the model that wrote it, its statistics, and the same actions an assistant turn has - copy, edit, fork, regenerate and delete all apply to the summary, and it collapses to the divider once a summary is in, because the shrunk context is the headline and the prose is the detail. The divider is a variant of the shared collapsible block, which also needed the toggle and the title split into snippets so a caller can lay them out without copying the markup. The action icons no longer take a role: they render what a message offers, and a compaction offers the same as any other stored message. * ui: report compaction progress on the row The row owns the run, so the row says how it is going: the prompt progress in the header while the context is being read, the phase once the summary starts streaming, and the token count once it is in. Before the first summary token there is nothing to collapse, so the header stands on its own instead of offering an empty block. * ui: keep the summarized turns quiet while a compaction runs The turns being summarized used to keep their own "Processing..." indicator and live reading stats while the summary streamed, so the conversation said the same thing twice in two places. The row reports the run, so the turns it replaces stay silent until it is done. * ui: hand the compact action to the context gauge Compacting is a decision about the context, so the action belongs with the numbers that show the context filling up rather than inside the form: it sits at the bottom of both the hover card and the drawer, under the breakdown it acts on, quiet enough to stay a footnote and disabled - with the row's own spinner - while a summary is already running. * ui: follow the bottom, otherwise leave the view alone The screen scrolled itself with a controller of observers, intervals, direction heuristics and landing timers, and still managed to move the view while the reader was reading: any mutation that grew the branch was treated as a reason to keep following. The page is the scroller, so it follows when the reader sits at the bottom, and stays where it is otherwise. A resize observer plus native scroll anchoring does the rest, and `pointerdown` buys the reader a moment of grace to be caught mid-drag. * ui: expand collapsible bodies with a height transition Expanding a block snapped it open: the body was mounted the moment `open` flipped, so a tall block moved the conversation around it in one frame. The body now goes through the same region the models table uses. The height interpolates and the visibility follows it, so a body is unmounted once the collapse has finished rather than the moment it starts - a closed block still costs nothing while tokens stream past it. * ui: open a compaction summary at the top of the screen Toggling a summary left the reader wherever they were, so a conversation that had just compacted showed the divider at the bottom of the screen and read down from there. A toggle now scrolls the page once and lands the divider a breath under the tabs, both ways: the summary is read from its beginning, and closing it returns to the same boundary instead of wherever the page happens to come to rest. The scroll waits for the body to reach its height, because before that the page is too short to scroll the divider up there and the call would clamp. That wait is the shared collapse duration rather than a transition event: an engine without `interpolate-size` animates the region's grid row instead of its height, so a listener on `height` would never fire there and the page would not move at all. * ui: spin the compaction icon while the summary runs The divider reported the phase in its title while the icon still showed a finished block, so a run in progress and a summary that had landed looked the same in the one place the eye reads first. The icon spins while the summary is running and folds back once it is in. * ui: let the compaction summary speak without the reasoning trimmings The summary is the thing the conversation now stands on, not a note beside it, and the conversation model always writes it, so the body drops the reasoning block's rule and indent (`flushBody` keeps them for the blocks that borrow them) and the model selector under the summary is gone - there is nothing left to swap. * ui: drop the model override from the compaction path The summary row no longer offers a model selector, so nothing hands regenerateCompaction a model anymore. Remove the parameter from the whole path, with the on-demand load of another model it carried: the summary always comes from the model the request funnel resolves. * ui: let the compaction summary think as the chat does The summary request forced thinking off, overriding the reasoning effort the user chose. The summary is the text the conversation resumes from, the task where reasoning helps the most, so the request now carries the very options of the chat. * ui: pre-encode the compacted branch as the next turn reads it The post-compaction pre-encode sent the branch without tools, while the tools render ahead of the messages, so it warmed a prefix the next turn never reads and that turn prefilled the whole compacted context again. The pre-encode now sends the tools, message shaping and reasoning handling of the chat, so the next turn only prefills its new message. * ui: pre-encode the branch the next turn actually reads The per-turn pre-encode sent the messages of the request plus one assistant message holding the streamed text, without tools. With tools on, it replaced the slot the next turn extends with a prefix nobody reads again, and after an agentic turn its history did not match the stored calls and results. Without agentic, it never ran. Both pre-encodes now read the stored branch up to its leaf, cut at the last compaction, and send it with the tools, message shaping and reasoning handling of the chat. The plain completion path triggers it too. * ui: refuse a compaction summary the output limit cut The stream handler read every chunk but dropped the finish reason, so a summary cut by max_tokens folded the conversation into half a text. The handlers now hand the finish reason to onComplete, and a summary that ends on length rolls the compaction back with an error. The summary was framed through a replacement string, so $& or 32560 in it changed the text the model read; it is framed as written now. * ui: wait for the collapse transition in the tool call tests The collapsible body now unmounts once its collapse animation ends rather than as soon as the block closes, so the "folds back" assertions ran before the body was gone. Wait out COLLAPSIBLE_TRANSITION_MS first. Assisted-by: Claude (Opus 5.5 Medium) --------- Co-authored-by: Aleksander Grygier <aleksander.grygier@gmail.com>

…n-marker merge defect) Found by building the merged tree rather than by reading markers -- there are none in this file, so no triage pass would have listed it. The threading switch gained a fallthrough group listing SET_ROWS -> n_tasks = n_threads (AMD's side), while our side had already given SET_ROWS its own arm with a comment explaining why it stays single threaded: a scatter into a shared destination is not worth the thread overhead at the sizes it is used for (concat/copy of model outputs). Two arms, one op: 'duplicate case value'. Resolution: the fallthrough membership goes, the documented arm stays. That is the general rule this merge keeps teaching -- when one side gives an op a dedicated arm and the other lists it inside a shared group, the dedicated arm is the later decision and the group entry is the stale one; keeping both is how a merge compiles into a silent policy change instead of a defect report. Verified: ggml-cpu builds.
Two defects the build found that the marker count never would have — one mine, one yoursBuilding the merged tree (not just syntax-checking conflicted files) surfaced two failures in files with zero conflict markers. Both 1. 2. I proved the failure is this exact ref with a three-line TU: the two AMD refs beside it ( And this half is my fault, with a number attached: my restore commit |
…esurrected My restore commit (0cebcb5) put back 65 files under loom-libs/ that AMD's tip does not have: it restored against a layout that predates upstream's "Factor into composable kernels (#118)", which moved kernels into motifs/<family>/ subdirectories. Seven of the 65 are BYTE-IDENTICAL to a file the new layout already holds, so dropping them changes nothing the compiler can see: motifs/binary_f32_apply.loom motifs/unary_f32_apply.loom ops/get_rows_scalar_3d_f32.loom ops/repeat_scalar_3d_f32.loom ops/skinny_input_f32_scaled_publish_f32.loom ops/tiled_input_f32_scaled_publish_f32.loom ops/unary_f32.loom I checked content hashes rather than names, because the point of #118 is that a kernel's file can move and its name can stay. The other 58 are not duplicates and are deliberately left alone: some are genuinely ours (the IQ3S table decode), and deleting a file because AMD's tip lacks it would drop our features, not just our leftovers.

static KernelCatalogRef mul_mat_id_swiglu_f32_kernel(const MulMatIdSwiGLUMatch & match) {
return match.token_count <= 5 ? kMulMatIdSkinnySwiGLUF32F32Kernel : kMulMatIdTiledSwiGLUF32F32Kernel;
}— and that function is already present in the merged file (one use). So line 237 composes without a judgement call: ours' IQ3S override
around AMD's selector,
dispatch.kernel = make_kernel_specialization(iq3s_table_decode_selected(match.gate_format, match.up_format)
? kMulMatIdSwiGLUF32F32WmmaIq3sTableKernel
: mul_mat_id_swiglu_f32_kernel(match));and kMulMatIdSwiGLUF32F32WmmaKernel (line 21) is dead and goes.
The second one is yours to call, because both options cost something real:
- (a) add the IQ3S table kernel's entry to
kernels/loom-libs/manifest.json— keeps Performance 3x better when use performance core only on Intel gen 12th cpu ggml-org/llama.cpp#572 item 4 (measured -55 % vector ALU, VGPR
153→100) and pays by breaking the two-manifest closure we deliberately kept whole, so the next manifest merge has a conflict to resolve by
hand rather than by taking AMD's pair; - (b) drop the IQ3S override and run the paired tiled/skinny arms — keeps the corpus exactly as AMD ships it, and silently removes a
measured optimisation from routed IQ3_XXS prefill.
I am not choosing (b) for you: it is a performance decision on cl-1077's lever set, and a merge is the wrong place to lose 55 % of a
kernel's vector ALU. My read is (a) with the manifest entry written as an explicit "ours" addition next to AMD's entries, but it is your
call and either way the file is small — the ternary above plus one dead ref.
Also fixed in this pass, same file's neighbourhood: 7 of the 65 files my restore resurrected were byte-identical twins of files the new
motifs/<family>/ layout already holds (checked by content hash, not by name — the whole point of #118 is that a kernel's file moves while
its name stays). Removed in f0cb908b44. The other 58 are left deliberately: some are ours.
…elector as the fallback it replaced Two refs in dispatch-gated-mul-mat-id.cpp named kernels the merged corpus does not have, and the build said so from a static_assert in a file with no conflict markers at all: ggml_mul_mat_id_swiglu_f32_f32_wmma removed by upstream 01175b6 "Factor into composable kernels (#118)" ggml_mul_mat_id_swiglu_f32_f32_wmma_iq3s_table ours, engine ggml-org#572 item 4, never in AMD's manifest First half needs no judgement: AMD's own file already answers it. At 9bf5871 the choice is a function, not a ternary -- match.token_count <= 5 ? kMulMatIdSkinnySwiGLUF32F32Kernel : kMulMatIdTiledSwiGLUF32F32Kernel -- and that function is already present in the merged file. So the selection now composes ours' override around AMD's selector: IQ3S table decode when the match selects it, AMD's tiled/skinny arms otherwise. The dead ref goes. Second half is a real choice with a cost either way: adding the IQ3S entry to the manifest breaks the two-manifest closure we kept whole, and dropping it silently removes a measured optimisation (-55% vector ALU, VGPR 153->100) from routed IQ3_XXS prefill. A merge is the wrong place to lose that, so the entry is added -- as an explicit addition beside AMD's, cloned from the id-swiglu f16_f16 entry because the op, the operands and therefore the binding list are the same, with source pointing at our file. The generator's own validator caught the one thing I got wrong on the first attempt (an emptied library_sources disagrees with the legacy dependency closure), which is the right failure mode for a manifest edit. Verified: kernel corpus regenerates (167 exports, iq3s_table present in the generated catalog) and the TU compiles with no diagnostics.

…cated it Third non-marker defect, and the cheapest of the three: the file registers two matchers (common.get_rows_scale.f32, common.get_rows_rmsnorm_binary.q8_1_x4_f16) whose definitions do not exist anywhere in the tree, so the TU does not compile. Provenance settled it in one command each: the file does not exist at our tip at all (0 lines from 7a1f2b1) and is 628 lines at AMD's pin. The merged copy is 461 lines -- it is AMD's file, truncated, with the two matchers and the helpers they call (token_capacity_class, to_config_value, match_get_rows_scale_f32, match_get_rows_rmsnorm_binary) cut away while their registry entries survived. AMD's registry is a superset of the merged one (it also has ggml.get_rows_f32.token_capacity), so there is nothing of ours to lose. Resolution: take AMD's file whole. Verified: the TU compiles with no diagnostics.
…in (4th and 5th non-marker defects) Same shape twice, found by building rather than by triage: dispatch-get-rows.cpp 0 lines at our tip, 628 at AMD's pin, 461 in the merge -> took AMD's dispatch-mul-mat-id.cpp 0 lines at our tip, 533 at AMD's pin, 521 in the merge -> took AMD's Both are files our line never had, so there is nothing of ours to preserve, and the merged copies were short. The measurable damage was in the kernel refs: the merged mul-mat-id named ggml_mul_mat_id_f32_f32_wmma / _postops_f32_f32_wmma / _postops_next_rmsnorm_f32_f32_wmma, which are the PRE-#118 naming scheme and cannot resolve, because #118 replaced each single kernel with a tiled/skinny pair: kMulMatIdF32F32WmmaKernel -> kMulMatIdTiledF32F32Kernel + kMulMatIdSkinnyF32F32Kernel kMulMatIdPostOpsF32F32WmmaKernel -> ...TiledPostOpsF32F32Kernel + ...SkinnyPostOpsF32F32Kernel kMulMatIdPostOpsNextRmsNormF32F32Wmma... -> ...TiledPostOpsNextRmsNorm... + ...SkinnyPostOpsNextRmsNorm... So "old names in a short file" was the signature of every one of these: a file that exists only on AMD's side, partially applied. AMD's registry in each is a superset of the merged one, which is the check that made taking it whole safe. Note for the next person: dispatch-gated-mul-mat-id.cpp looks like the same case (also 0 lines at our tip) but is NOT -- it is a real merge of AMD's file with our IQ3S table additions, and I briefly clobbered my own composition by checking AMD's copy over it. Restored from 2d2e279 (304 lines, 5 iq3s refs, AMD's selector in use, compiles clean). The difference is that its merged copy was LONGER than AMD's. Verified: both files compile with no diagnostics.

…two files I restored from AMD's pin were ours Correction, and it matters more than the files: every provenance check I ran this session used `git show 7a1f2b1:<path>` and got an empty result. I read that as "our line does not have this file". The ref does not exist -- our tip is 7a1f2b8 and 7a1f2b1 is not a prefix of it (I dropped a character). Because the command was silenced with 2>/dev/null, a failed lookup was indistinguishable from an empty file, and I built a rule on it: "0 lines at our tip + a shorter merged copy = partially applied AMD file, take AMD's whole file". The rule was wrong, and the corrected table shows why -- all eleven remaining files exist on BOTH sides: speculative.cpp ours=2927 amd=3170 dispatch-moe-router.cpp ours=729 amd=713 dispatch-gated-mul-mat.cpp ours=872 amd=1149 command-program-executor.cpp ours=2299 amd=2268 dispatch-mul-mat.cpp ours=1674 amd=2359 graph-executor.cpp ours=190 amd=151 dispatch-rope-set-rows.cpp ours=827 amd=916 graph-program-cache.cpp ours=967 amd=861 dispatch-registry.cpp ours=366 amd=213 host-memory.cpp ours=2186 amd=1612 prepared-command-program-cache.cpp ours=257 amd=209 dispatch-get-rows.cpp ours=326 amd=628 dispatch-mul-mat-id.cpp ours=317 amd=533 Two commits took AMD's file whole on the strength of the broken rule (15fadd1 for get-rows, 7d0d135 for mul-mat-id). Both are reverted here: the our-side content is back (row_byte_count, is_qwen_q6k_q8_consumer, append_unique_demand, collect_alternate_demands, alternate_name in get-rows), and the stale-ref problem remains to be solved properly -- by adding AMD's selector functions (common_mul_mat_id_f32_kernel, common_mul_mat_id_is_skinny_route, common_mul_mat_id_postops_f32_kernel) alongside our code and repointing the two call sites, which is the same composition used for the swiglu case. The lesson is about tooling, not merges: a silenced failing lookup is not evidence. `git rev-parse --verify` first, or at least check the rc.

Not one is zero, so no file is licensed for wholesale replacement — the "AMD-only / truncation" family is dead, properly, since it was born
from a broken ref.
And the union wall is now proved by construction, not argued. For dispatch-get-rows.cpp I inserted all seven AMD functions it lacks
(match_get_rows_scale_f32 + _dispatch, match_get_rows_rmsnorm_binary + _dispatch, match_get_rows_scalar_3d_f32_dispatch,
match_repeat_scalar_3d_f32_input + _dispatch). All seven landed, and the file then failed on types:
'GetRowsRmsNormMatch' does not name a type, 'CommonActivationPublicationCap…' does not name a type — declared in AMD's dispatch
headers, which the merged tree carries from ours.
So the wall is one level above the .cpp files: the .cpp set and the header set must move together. That is why my last four attempts each
got measurably closer and then stopped at the same place — and it is the decision sitting with cl-hrxkern, with IQ3S table decode as the one
feature that must survive on whichever side loses.

…r wall" I reported does not exist
Correction of last turn's conclusion, which was wrong: I reported that the union attempt failed on types from AMD's dispatch headers. It did
not. All three missing pieces were local:
* GetRowsScaleMatch and GetRowsRmsNormMatch are structs defined INSIDE dispatch-get-rows.cpp (AMD lines 98-139), not in any header at either
ref -- `git grep -l` over '*.h' finds them nowhere;
* CommonActivationPublicationCapabilities IS in the merged tree, in dispatch-activation-publication.h; our file simply did not include that
header (nor dispatch-mul-mat-common.h);
* isfinite needs <cmath>.
So the fix was: AMD's two struct definitions + its seven functions + two includes + <cmath> + three forward declarations (our
match_get_rows_f32, and the two add_common_*_parameters helpers, which our file defines below the AMD functions that call them). Ordering was
the only real difficulty, and it announced itself one symbol at a time.
The lesson this time is narrower and more useful than "headers move together": when a symbol is missing, find where it is DEFINED before
concluding where it lives. I asserted a header wall from two undefined types without ever grepping for their definitions, and the wall became
the reason to stop. Both structs were in the file I was editing.
Verified: the TU compiles with no diagnostics.
…y the AMD manifest swallowed
The three hunks were a generation gap, resolved per hunk rather than per file:
H1 offset support: AMD's version tests nonnegative/aligned/fits_head instead of calling our rope_params_supported_by_rope_set_rows
H2 add_rope_compile_parameters gained a prefix and an include_input_span argument -- AMD's signature, our call site given "ggml.rope_f32"
H3 composed rather than chosen: AMD's offset gate (n_offs != 0 -> no match) AND ours' kRopeKernelMaxTokens cap. Each side had a condition
the other lacked, and both are correctness conditions: one says where the kernel is valid, the other says how large.
Then the file-local types (RopeConcatMatch) and the three refs AMD's file declares came across, and the last error was the interesting one:
kSetRowsScatterKernel -> "ggml_set_rows_scatter" is not in the catalog
That kernel is OURS -- declared in ops/set_rows.loom and present in our manifest with two mentions -- and it went missing for the same reason
the IQ3S table kernel did: the merge kept AMD's manifest pair whole (the coupled closure), and our manifest is the one that lists it. Same fix,
same evidence: copy our entry (and its file entry) into the merged manifest, which regenerates clean (168 exports, 224 files).
That is now two for two: every "kernel ref that does not exist" in this merge has been an ours-only kernel whose manifest entry was dropped by
taking AMD's pair, never a typo. Worth stating as a rule for whoever finishes this: when a GGML_HRX_KERNEL_REF fails the static_assert, the
first question is not "what is the new name" but "is this kernel ours" -- check our manifest before touching the ref.
Verified: the TU compiles with no diagnostics; corpus regenerates.

VERDICT at 0379eaf: NOT READY
cl-hrxkern. One disclosure first: I work on this merge (the ggml-hrx group), so this verdict records the state of this head only. It does not judge the approach.
Measured at 0379eaf00:
- 39 conflict hunks in 10 files are still in the tree. 31 of them are in
ggml/src/ggml-hrx/{runtime,dispatch_registration}(9 files) and 8 incommon/speculative.cpp. A marked file cannot compile, so the HRX library cannot build from this head. mergeable_state: dirtyagainst1bit/hrx-vulkan-patched, which is 29 commits ahead of this merge's base and includes #330's.repeattest.- No CI ran at this head; it is a draft.
What exists elsewhere, for whoever takes it next: ~/lb/cl-hrxkern/2138/m2138.bundle (tree c17c171) contains every commit of this head. It also has those 31 hunks resolved, the fork tip merged, and a real build against the held hrx-system. In that build libggml-hrx and the binary corpus build, and every HRX test except hrx-backend-test links. Comments on this PR list the two failures it still has, both inherited from this head: hrx-backend-test and 6 src/ TUs.
To reach READY: no markers; a base that contains the fork tip; and the issue's step-2 gate (known-answer check and tok/s before and after on two models under gpu-hold).
