docs(paged): record P6 fp8-KV measured NO-GO - throughput dead end, capacity-play open

Retry of P6 unblocked the prior infra-block (DGX reachable via ssh dgx.casa) and
ran the kill-gate. Two measured artifacts replace the analytical estimates:

Stage 0a decode ceiling (v2 per-kernel decode-isolation, cross-checked within
0.3% of the batched-bench wall t_tg): fp8-KV theoretical-MAX decode saving
(fa-only) tops at +8.81% at ctx8192 x npl8 and clears +3% only at long context;
standard npl128 serving shapes reach +2.2/+3.4%. This refutes the earlier
analytical prior (0.65% std, +17.34% ctx8192) in both directions.

Stage 0b zero-code Q8_0-KV A/B proxy at the highest-ceiling shape (5 reps/arm):
dense ctx8192 +0.37% decode (flat), moe ctx8192 -2.63% decode REGRESSION. Even
Q8_0 - which wins on the integer DP4A fattn-vec dot that e4m3 cannot use -
realizes ~none of the ceiling; dequant-in-attention eats the KV-read BW saving,
re-confirming the historical Q8_0 +7.8% null. e4m3's KQ path is strictly worse
than Q8_0's, so the e4m3 throughput kernel is a definitive NO-GO and was not
built. The capacity-play (halving the 10/40 attention layers' KV footprint)
stays open as a footprint feature.

Default path measured green on the byte-identical worktree (canonical greedy-md5
re-run: MoE 8cb0ce23, dense 5951a5b4, paged). Fork localai-paged untouched at
653bb2f3d; topic branch p6-fp8-kv retained on the DGX, not pushed; series stays
46 patches (0001-0055). P3's landed program conclusion is preserved; only the
now-stale P6 status descriptors in it were corrected to the measured NO-GO.

-## Offering several builds of one model (`variants`)
-
-When the same model is published in more than one quantization, or is also
-servable by another engine, add each build as its own ordinary gallery entry and
-then point one of them at the others with `variants`:
-
-```yaml

-  # ... the usual urls / overrides / files for the Q4 build ...
-  variants:
-    - model: nanbeige4.1-3b-q8
-```
-
-Rules:
-
-- The declaring entry is a **complete, normal entry**. It keeps its own
-  `files`/`overrides` and stays installable on every host and by every older
-  LocalAI release, which simply ignore `variants`.
-- A variant references another gallery entry **by name**. That entry must exist
-  and must not declare `variants` of its own.
-- **A referenced entry keeps its own gallery row by default.** It is hidden only
-  in the collapsed listing (`collapse_variants=true`, which the web UI requests
-  by default), where the declaring entry stands in for it. Searching there still
-  matches the referenced entry and answers with the entry declaring it, so
-  referencing an entry never makes it unfindable; turning the collapse off
-  returns it under its own name.
-- **Order carries no meaning.** Do not try to encode a preference; write the
-  list in whatever order reads best.
-- **A variant may be smaller than the declaring entry.** Offering a downgrade
-  for small hosts is a normal shape: the declaring entry's own build competes
-  like every other candidate, so a large host keeps the large build.
-- **Do not describe hardware.** At install time LocalAI drops variants whose
-  backend cannot run on the host, then drops those that do not fit available
-  memory. The declaring entry's own build is exempt from both filters, so
-  selection always terminates on something installable. Sizes are measured live
-  from the weights and cached, so nothing has to be written down.
-- **Engine preference outranks size.** Among the builds that survive the
-  filters, the host's preferred engine wins first and only then does the larger
-  footprint win. On NVIDIA a vLLM build beats a larger llama.cpp one; on Apple
-  silicon an MLX build beats a larger GGUF one; on a host with no preference for
-  either engine the larger build wins, since a bigger footprint is a higher
-  quality quantization of the same weights. Predict what a user gets by asking
-  which engine the host prefers before asking which build is biggest. The
-  per-capability order lives in `engineNamePreferenceRules`
-  (`pkg/system/capabilities.go`); see
-  [adding-backends.md](adding-backends.md) for how a backend gets into it.
-- **Serving feature preference sits between engine and size.** Among builds on
-  an equally preferred engine, one that speculates or predicts several tokens
-  per step beats the plain build of the same weights, because it answers faster
-  for the same output: a `dflash` build beats an `mtp` one, and either beats a
-  plain build. The order lives in `servingFeaturePreferenceTokens`
-  (`pkg/system/capabilities.go`) and is matched against the entry's `tags:` and
-  **nothing else**: not the entry name, not `overrides.options`. See
-  [the tagging rule](#the-dflash--mtp-tagging-rule) below. Engine deliberately
-  outranks it: a serving feature makes the right engine faster, it does not make
-  a wrong engine right. Fit still outranks both, so a drafter pairing (strictly
-  larger than the plain build, since it ships a drafter alongside it) is dropped
-  on a host too small for it before this order is ever consulted.
-- A variant is nothing but a name; there is no per-variant memory field. When
-  the measured size for a build is wrong, correct it on the referenced entry by
-  setting that entry's own `size:` (e.g. `size: "20GiB"`). The estimator prefers
-  a declared size over its own guesswork, so the fix applies everywhere the size
-  is shown or compared rather than only to variant selection.
-
-Users can override the automatic choice with `variant` on `POST /models/apply`,
-`local-ai models install --variant`, or the `install_model` MCP tool. See
-`docs/content/features/model-gallery.md`.
-
-The gallery lint specs live in `core/gallery`, so run that suite after adding a
-`variants` list.
-
-### The `dflash` / `mtp` tagging rule
-
-**Tag an entry `dflash` or `mtp` when the entry actually configures that
-feature. Variant ranking reads the tag and nothing else.**
-
-Decide by looking at what the entry configures, in whatever vocabulary its
-backend uses:
-
-| Backend | Configures the feature when it declares |
-|---------|------------------------------------------|
-| `llama-cpp` | `overrides.options` contains `spec_type:draft-dflash` or `spec_type:draft-mtp` |
-| `ds4` | `overrides.options` contains `mtp_path:` / `mtp_draft:` |
-| `sglang` | the referenced `gallery/*.yaml` sets `speculative_algorithm:` |
-
-That check is curation-time only. `spec_type` is llama.cpp's config vocabulary,
-and a cross-backend ranking decision must not depend on one backend's option
-syntax, which is precisely why the ranker reads the tag instead of the options.
-
-Two mistakes the rule exists to prevent:
-
-- **Weights that carry the heads are not an entry that enables them.** The
-  NVFP4 GGUF entries ship MTP-bearing weights but set only `use_jinja:true`, so
-  they enable no speculative decoding and must NOT be tagged. Tagging them wins
-  them the feature axis without being any faster.
-- **A name is not a declaration.** An entry whose name spells `-mtp` while
-  configuring nothing gets no tag, and an entry that configures the feature is
-  tagged even when its name says nothing (`hy3`, `glm-5.2`). Ranking never reads
-  the name, so an untagged build that does enable the feature is simply ranked
-  as plain rather than promoted on a marker nobody meant.

This avoids Playwright's downloaded browser, which can't resolve system libs (`libglib-2.0`, …) on NixOS. In CI (no `PLAYWRIGHT_CHROMIUM_PATH`) the Makefile falls back to `playwright install --with-deps chromium`.

 - **Why it has a tolerance (unlike the strict Go gate):** UI e2e coverage is *non-deterministic*. Specs that assert on state and end while async/lazy render work is still in flight collect those lines only when the render beats the coverage teardown — so the total drifts with machine speed/load (a fast local box reads higher than a slow CI runner), diffusely across many specs. The tolerance absorbs that drift, so set the baseline *below* the slow-CI floor, never to a fast-local `make test-ui-coverage-baseline` number, or CI flaps.
 - **Raising coverage is cheap:** a *render-smoke* spec (navigate to a route, assert its header renders) mounts a lazy page and runs its full render + initial effects, capturing most of its lines in a few lines of test — see `e2e/page-render-smoke.spec.js`. Auth is disabled in the test server (`isAdmin=true`), so `RequireAdmin`/`RequireFeature` routes render without a mock. The most *deterministic* win is removing a race: make a spec `await` a rendered element before ending (see `e2e/agents.spec.js` → AgentCreate) so its lines count every run.
 
 Rules (both gates):
-- **Don't weaken the gate:** never hand-lower a baseline or widen a tolerance to turn a red gate green. The ratchet only moves up.

+- **Don't work around the gate:** never `git commit --no-verify`, and never hand-lower a baseline or widen a tolerance to turn a red gate green. The ratchet only moves up.
 - If a change drops coverage, **add tests** (sort `coverage-summary.json` by line% ascending to find untested code) rather than editing the baseline. When coverage legitimately rises, commit the regenerated baseline (`make test-coverage-baseline` / `test-ui-coverage-baseline`).
 - The Go gate is **strict — no tolerance**; `covermode=atomic` keeps it deterministic. The UI gate keeps a small tolerance only because its e2e coverage isn't.

-Deliberately excluded: `backend/index.yaml` (gallery metadata, never enters an image), `.github/backend-matrix.yml` (adding a backend would rebuild all of them), `backend/Dockerfile.base-grpc-builder` (owned by `base-images.yml`), and the root `Makefile` (touched in ~11% of commits, and its backend-relevant edits arrive alongside the backend directory anyway). `make test-ci-scripts` pins all of this.
-
-#### `backend/backend.proto` is content-filtered, not path-filtered
-
-Every language consumes the proto, so a path rule for it can only ever say "rebuild all 473 images". It changes in ~1.3% of commits, and that was enough to make it the single largest CI cost driver in the repo: on 2026-07-29 four runs totalling 935 queued jobs traced to nothing but a proto edit, one of which (#11158) was a six-line diff adding `bool cache_prompt = 8;`.
-
-An additive proto edit cannot change how a backend that never references the new symbol behaves, so `filterMatrix()` suppresses the rule for one. `changed-backends.js` fetches `backend/backend.proto` at the base revision (same contents-API pattern as `.github/backend-matrix.yml`) and hands both texts to `protoChangeIsAdditive()`, which compares them structurally rather than textually:
-
-- **Additive, rebuilds nothing**: a new field with an unused number, a new message, a new enum value, a new RPC. Comment, whitespace and ordering changes also land here.
-- **Breaking, rebuilds everything**: a removed, renumbered, retyped or renamed field, a dropped RPC, a changed `option` or `package`. So does an unresolvable base revision, matching the run-all posture used for a truncated diff.
-
-Checked against every proto commit in the preceding six months, all nine resolvable ones classify as additive. Note the tradeoff this accepts: generated stubs do change for an additive edit, so image bytes would differ on a rebuild even though behavior does not. That is the same standard already applied when the filter declines to rebuild on unrelated `pkg/` changes, and the weekly cron remains the backstop.
-
 The Sunday 06:00 UTC cron on `backend.yml` exists specifically because path filtering can leave Python backends frozen on stale wheels. `DEPS_REFRESH` (below) only fires when the build actually runs, so an untouched Python backend would never re-resolve its unpinned deps. The weekly cron is the safety net.
 
-## Content-blind PRs skip the workflows that cannot see them
-
-`backend_pr.yml` and `test-extra.yml` filter themselves (matrix generation and a `detect-changes` job), so a gallery-only or docs-only PR costs them about one job each. The Go and image workflows had no filter of any kind, so a one-line `gallery/index.yaml` edit queued 20 jobs, and a docs-only PR queued the same.
-
-This is worth more than it looks. Measured over the week to 2026-07-30, **97% of CI wall-clock is queueing, 3% is execution** (median queue ~5h against a 4-20min median job). Cutting job count is therefore the only lever that shortens feedback time; making individual jobs faster moves 3%.
-
-The volume is real: 13 gallery-only PRs merged that week with 10 open at once, and 78 of the 137 PRs opened were bot-generated.
-
-`paths-ignore` on the PR trigger of `image-pr.yml` (7 jobs), `build-test.yaml` (3), `lint.yml` (2) and `tests-e2e.yml` (1) drops 13 of those 20. The excluded set:
-
-| Path | Why no image or Go build can see it |
-|---|---|
-| `gallery/**` | Model-gallery metadata, parsed at runtime, never copied into an image |
-| `docs/**`, `examples/**`, `**/*.md` | Never enter an image or a binary. `lint.yml` already excluded these before gallery was added |
-
-### `backend/{cpp,go,python}/**` on `image-pr.yml` and `build-test.yaml` only
-
-Version-pin bumps dominate PR volume: 48 `update/*` PRs in the week to 2026-07-30, from 16 pins, each a two-line diff. Most edit nothing but one `backend/*/<name>/Makefile`.
-
-Neither of those two workflows can observe such a change. `make build` is `go build ./cmd/local-ai`, GoReleaser builds the same plus `./cmd/launcher`, and the core image's final stage ships only `entrypoint.sh`, `healthcheck.sh` and that binary. The per-backend trees are copied into the builder but nothing in them reaches the output.
-
-What still triggers a full run, because none of it lives under those prefixes:
-
-- `backend/backend.proto` — feeds `protogen-go`, so it does change the binary.
-- `go.mod` / `go.sum` — the `go mod tidy` before-hook.
-- `backend/Dockerfile.*` and anything else directly under `backend/`.
-
-Deliberately **not** applied to:
-
-| Workflow | Why it must keep seeing `backend/**` |
-|---|---|
-| `test.yml` | `TEST_PATHS` explicitly includes `./backend/go/cloud-proxy/...`, `./backend/go/local-store/...` and `./backend/go/valkey-store/...` |
-| `lint.yml` | `.golangci.yml` carries `backend/`-scoped rules, so golangci-lint covers that tree |
-| `tests-e2e.yml` | The e2e suite drives real backends over gRPC |
-| `backend_pr.yml` | This is the workflow whose entire job is to rebuild the changed backend |
-
-What still runs, and why it has to:
-
-| Workflow | Why it keeps running |
-|---|---|
-| `test.yml` (`tests`) | `core/gallery/variants_lint_test.go` reads the real `gallery/index.yaml` and asserts the index invariants (no duplicate entry names, no build claimed by two parents). This is the only schema-level check the gallery has. |
-| `yaml-check.yml` (`Yamllint`) | Lints `gallery/` for syntax. |
-| `backend_pr.yml`, `test-extra.yml` | Already self-filtering; they stop after the detect step. |
-
-Two properties this relies on:
-
-- `paths-ignore` skips a run only when **every** changed file matches, so a PR touching the gallery *and* Go code still runs everything. That is what makes the exclusion safe rather than a hole.
-- `master` carries no branch protection and no rulesets, so a skipped workflow reports no status and nothing waits on it. If required status checks are ever introduced, these four entries must be excluded from the required set or PRs will hang on "Expected — Waiting for status to be reported".
-
-### `image.yml` on master push is gated too, by a job rather than a path filter
-
-The same reasoning applies to master pushes, and the volume is larger there: on 2026-07-30, **12 of the 23 queued `image.yml` runs** were commits like "add 1 new model to gallery" or a docs fix, each rebuilding all 18 container images.
-
-`image.yml` now has a `changes` job that decides once whether the push can affect any image; the other 11 jobs carry `needs: changes` plus an `if:` on its output. Verified against the shipped `Dockerfile`: the final stage copies only `entrypoint.sh`, `healthcheck.sh` and the `local-ai` binary, there is no `go:embed` of `gallery/` or `docs/`, and the gallery is fetched at runtime from `github:mudler/LocalAI/gallery/index.yaml@master`. A gallery-only commit therefore produces byte-identical images, and the gallery change reaches users through GitHub immediately whether or not an image is rebuilt.
-
-Two properties to preserve if you touch it:
-
-- **It is a job gate, not `paths-ignore`.** `paths-ignore` on `push` also applies to tag pushes, and a tag created on an existing commit carries an empty commits list, which would silently skip the release image build. The gate short-circuits to "build" for `refs/tags/*`, and for any push whose base commit is missing, zero, or unresolvable.
-- **The merge jobs must name the gate explicitly.** They use `if: ${{ !cancelled() && ... }}`, and `!cancelled()` is true when a dependency is *skipped*, so without the extra condition they would run and try to merge manifest lists for images that were never built.

-### ⚠️ This ccache does nothing in CI today
-
-This section previously claimed that `cache-to: type=registry,mode=max` "exports the cache mount data into the registry cache, so subsequent builds restore it". **That is not true.** BuildKit does not export the contents of a `--mount=type=cache` to a registry cache export. A cache mount lives in the builder's local state, and every CI job gets a fresh runner with a fresh builder, so `/root/.ccache` starts empty on every single build.
-
-Measured on 2026-07-30 from the `ccache -s` output the compile script already prints (it runs `ccache -z` first, so the numbers are per-build):
-
-| Job | Commit touched | Build time | ccache |

-| 90210828110 (llama-cpp, cublas 12.8) | `LLAMA_VERSION` bump | 5673s | **0 / 813 hits** |
-
-The first two are the decisive control: commit `90355cd44` changed exactly one file, `backend/go/magpie-tts-cpp/Makefile`, nowhere near llama.cpp. The engine source was byte-identical to the previous build, which is precisely the case this section says ccache should serve, and the hit rate was still **0.00%**. A cache that was being restored but merely matching poorly would show partial hits; 0-of-N is the signature of an empty cache.
-
-So the paragraph above about `LLAMA_VERSION` bumps reusing previous `.o` files describes an intended design that is not in effect. `Dockerfile.{llama-cpp,ik-llama-cpp,turboquant,bonsai,ds4,privacy-filter}` pay the ccache wrapper overhead and get nothing back. Multi-hour C++ rebuilds are recompiling identical translation units from scratch.
-
-**Do not "fix" this by adding cache mounts to more Dockerfiles.** Wiring the same mount into `Dockerfile.golang` (215 of the 434 matrix entries) was measured locally at 18% faster on a rebuild after a source edit, with a 71.5% ccache hit rate — but only because the local test reused one builder across both builds. In CI it would be a no-op for exactly the reason above.
-
-Making this actually work needs the cache to live outside the builder. The options, none of them free:
-
-- **ccache `remote_storage`** (ccache ≥ 4.4, HTTP or Redis backend) or **sccache** with an S3/GCS/Redis backend. Genuinely works across runners; needs a cache service to point at. quay.io is a registry, not a blob store, so the existing infra does not cover it.
-- **Round-trip the cache dir through `actions/cache` on the runner**: restore it, pass it in, and export it back out via a build stage output. No external infra, but clunky, and the repo already sits at GitHub's 10 GB cache ceiling while the llama-cpp ccache alone is capped at 5 GB.
-
-Until one of those lands, treat C++ backend builds as always-cold and spend the effort on not running them instead (path filtering, see above).
+On a `LLAMA_VERSION` bump, most translation units are byte-identical to the previous version's preprocessed source — ccache returns the previous `.o` and skips the real compile. Same for LocalAI source changes that don't actually touch llama.cpp's CMake inputs. Cache scope is per `(TARGETARCH, BUILD_TYPE)` so e.g. cublas-12 doesn't share with cublas-13 (their CUDA headers differ; cross-pollination would just be cache misses anyway).

-Enabling it also has a real cost. GitHub caps Actions cache at **10 GB per repo and the repo already sits at that ceiling** (31 entries), so every `setup-go` entry written by a branch with a distinct `go.sum` (222-375 MB on Linux, up to 1.4 GB on macOS) evicts something else.

+# llama-cpp-localai-paged Backend (paged attention + Blackwell NVFP4 decode)
+
+`llama-cpp-localai-paged` is LocalAI's **CUDA-only** paged-attention variant of the
+llama.cpp backend. It targets high-concurrency decode for the Qwen3.6 hybrid
+gated-DeltaNet (SSM) models on Blackwell (GB10 / DGX Spark). It reuses the stock
+`llama-cpp` backend's sources and applies a vendored patch series on top at build
+time. It is **not** a fork: a source-only `*.patch` stack plus one canonical doc.
+
+**Canonical reference:** `backend/cpp/llama-cpp-localai-paged/README.md`
+(architecture, the patch series 0001-0030, benchmarks, dev notes, generality,
+pin/canary policy). Read it for any technical detail; this guide is the maintenance
+how-to.
+
+## Where things live
+
+- `backend/cpp/llama-cpp-localai-paged/Makefile` - the thin wrapper. It copies the
+  stock `backend/cpp/llama-cpp/` build infra into a build dir, clones llama.cpp at
+  this backend's **own** pin (`LLAMA_VERSION`), applies the paged series via the
+  `apply-paged-patches` define (strict `git apply`), then builds `grpc-server`.
+- `backend/cpp/llama-cpp-localai-paged/patches/paged/` - the source-only `.patch`
+  series (0001-0030), nothing else.
+- `backend/cpp/llama-cpp-localai-paged/README.md` - the canonical doc. The
+  operational docs (`PAGED_BITEXACT_NOTE.md`, `UPSTREAM_LAYER2_SCOPE.md`) and
+  dev artifacts live in
+  `backend/cpp/llama-cpp-localai-paged/docs/`.
+- `backend/Dockerfile.llama-cpp-localai-paged`, `.docker/llama-cpp-localai-paged-compile.sh`
+  - the CUDA build entry points.
+- `backend/cpp/llama-cpp/` - the **stock** backend, pure upstream. It carries no
+  paged patches.
+
+## Invariants (do not break these)
+
+- **Stock stays pure.** The paged patches live ONLY in this backend. Never add a
+  `patches/paged/` dir or `LLAMA_PAGED` logic to `backend/cpp/llama-cpp/`.
+- **CUDA-only.** Ship cublas/cuda targets only. Off-CUDA the fusions are gated off
+  (patch 0030) and NVFP4 falls back to dequant, so the backend is neutral-to-
+  slightly-negative there - non-CUDA users use the stock `llama-cpp`. Do not add
+  cpu/vulkan/sycl/metal rows for this backend in `.github/backend-matrix.yml`.
+  (Those builds also fail to link `grpc-server` on darwin/arm64 against upstream
+  `stream_*` server symbols - another reason it is CUDA-only.)
+- **Source-only patches.** A `.patch` may touch only llama.cpp source - never a
+  dev doc or `*.md`. Strict `git apply` on a clean checkout must reach exit 0. (A
+  stray `SSM_DECODE_FIX_RESULTS.md` hunk in patch 0019 once broke the CI build.)
+- **Bit-exact by default.** Every shipped patch is byte-identical to the f32
+  baseline. (The one opt-in precision trade, `ssm_bf16_tau` / patch 0026, was
+  DROPPED: it went flat once the decode fusions landed - forcing all gated-DeltaNet
+  heads to bf16 gave 780.6 vs 780.0 t/s, zero benefit - so the series is now
+  bit-exact end to end. Do not reintroduce a per-head SSM-precision lever; see the
+  rejected-levers note in the backend README section 5.)
+
+## Fork-first workflow (MANDATORY)
+
+The fork **`mudler/llama.cpp` branch `localai-paged`** is the CANONICAL source
+of truth for ALL paged-backend kernel and patch work. The vendored
+`patches/paged/*.patch` series is a **derivative**: the fork is the source, the
+series is a generated mirror of it.
+
+**Always update the fork FIRST, in this exact order:**
+
+1. **Commit the change on the `localai-paged` branch and push it.** Every
+   kernel or patch change lands as a fork commit first.
+2. **Then regenerate the LocalAI series from the fork** via `git format-patch`
+   (one patch per fork commit, source-only) into
+   `backend/cpp/llama-cpp-localai-paged/patches/paged/`, so the series stays a
+   **1:1, drift-free mirror** of the branch.
+
+Hard rules, no exceptions:
+
+- **NEVER edit the `patches/paged/*.patch` files directly.** They are generated
+  output, not source.
+- **NEVER add a patch to the series that has no corresponding fork-branch
+  commit.** Every `.patch` must be the `git format-patch` of a real commit on
+  `localai-paged`.
+- The fork branch is **where the build and the per-path bit-exact md5 gate
+  actually run**, so it is the **only** place a change is truly validated. A
+  patch living only in the LocalAI series has never been built or gated.
+
+Verify the mirror by tree hash: applying the full on-disk series on the pin
+must reproduce the fork branch tree byte-for-byte. (The patch maintenance
+detail is in `backend/cpp/llama-cpp-localai-paged/docs/PATCH_MAINTENANCE.md`;
+the hard-gate is section 2.5 of `docs/PARITY_HANDOFF.md`.)
+
+## Maintaining the pin against new llama.cpp
+
+The pin (`LLAMA_VERSION` in the wrapper Makefile) is advanced ONLY by the manual
+pin-sync. It is deliberately **excluded from the nightly auto-bumper**
+(`bump_deps.yaml`): a naive bump would shift the tree out from under the patches
+and break `git apply` at build time.

+1. **The canary tells you when to sync.** `.github/workflows/llama-cpp-paged-canary.yml`
+   runs weekly: it applies + builds the series against the latest upstream tip and
+   goes **red** when upstream drifts past the patches. Canary red -> run a pin-sync.
+2. **The pin-sync** (recorded in the README section 7 and git history): rebase the series onto the new
+   tip (resolve conflicts; re-export **source-only** with a pathspec like
+   `-- src/ ggml/ common/ include/ tools/ tests/ cmake/`), rebuild on a CUDA box,
+   pass the bit-exact gate on **every** path + `test-backend-ops`, **and confirm
+   the full grpc-server build/link is green on CI**, then bump `LLAMA_VERSION`.
+
+**Hard constraint: keep the pin == the stock `llama-cpp` pin.** `grpc-server.cpp`
+is shared with the stock backend and tracks the stock pin. A paged pin that
+diverges PAST an upstream server-API refactor breaks the grpc-server LINK even
+when the patches are byte-for-byte bit-exact - the bit-exact gate alone does NOT
+catch it. The `c299a92c` bump did exactly this (patches applied + greedy-md5
+bit-exact, but `grpc-server.cpp` failed to link with undefined `stream_*` server
+helpers the refactor pulled into its headers), so it was reverted to `9d5d882d`.
+A pin bump is shippable only once the full CI grpc-server build is green, which in
+practice means moving in lockstep with the stock pin (or vendoring a
+pin-matched grpc-server.cpp, which we deliberately do not, to keep stock pure).
+
+## The bit-exact gate (run for every change)
+
+- greedy md5: `llama-completion -m MODEL -ngl 99 -fa on -p "The capital of France is" -n 48 --temp 0 --seed 1 </dev/null | md5sum`,
+  paged paths prefixed `LLAMA_KV_PAGED=1` (+ `LLAMA_MOE_FORCE_GRAPHS=1` for paged
+  MoE). Must match the recorded baseline. Redirect stdin from `/dev/null` or
+  `llama-completion` hangs in conversation mode.
+- `test-backend-ops` (CUDA0 vs CPU oracle) for every touched op (`SSM_CONV*`,
+  `GATED_DELTA_NET`, `MUL_MAT`, `MUL_MAT_ID`).
+- **The gate is per-path.** The paged-MoE md5 differs from the non-paged md5 - a
+  benign, KL-validated FP-accumulation-order difference (see `docs/PAGED_BITEXACT_NOTE.md`).
+  Compare a paged-MoE change to the **paged** reference, not the non-paged one.
+
+## Encapsulating your work
+
+- When you change a kernel, follow the **Fork-first workflow** above: commit and
+  push on the `localai-paged` branch first, then regenerate the `.patch`
+  (source-only) from the fork so this worktree mirrors the branch byte-for-byte.
+  Commit with sign-off.
+- New optimization -> next patch number (gaps 0005/0027 are intentional). Update
+  the README's patch table and dev notes - keep the README the single doc; do not
+  scatter `*_RESULTS.md` files.
+- Record rejected/flat levers in the README too (they stop the next person from
+  re-running dead ends).
+
+## Follow-ups (Metal / SYCL / Vulkan)
+
+The decode fusions are implemented for **CUDA + CPU only**. The base
+gated-DeltaNet + SSM_CONV ops already exist upstream on Metal, SYCL, and Vulkan,
+so the models **run** there via the non-fused path - what is missing is the
+fusion speedup. Porting it (strictly mirroring the CUDA kernels, since we have no
+Metal/SYCL/Vulkan hardware to test on here) is scoped in `docs/UPSTREAM_LAYER2_SCOPE.md`
+(recommended order: Metal, then SYCL, then Vulkan; ops-first upstream PR, then one
+PR per backend, each gated by `test-backend-ops` on the target hardware). The
+methodology for that work is in [.agents/vllm-parity-methodology.md](vllm-parity-methodology.md).

-# Preparing a Release
-
-A release is not finished when the tag is pushed. The GitHub release, the blog post and the demo clips ship together, because the changelog says what moved and the post and the clips are what make anyone care.
-
-## What a release must include
-
-1. **Labels on the merged PRs.** GitHub generates the raw notes from PR labels, so label first, generate second. Wrong labels mean a miscategorised changelog that has to be edited by hand.
-2. **`RELEASE_NOTES_vX.Y.Z.md`** at the repository root, in the house style: what changed, why it matters, PR numbers so people can read the diffs.
-3. **A blog post under `website/content/blog/`.** One post per release, front matter with `title`, `date`, `author`, `category: "Release"`, `tags`, `summary` and `extracss: ["blog.css"]`. Cover the two or three changes that alter what a user does day to day, not the whole changelog, and link the PR numbers. See `website/content/blog/what-landed-in-localai-4-8.md` for the shape.
-4. **Demo clips for the notable features.** Anything visible (a new backend, a UI change, a new endpoint, a measured speedup) gets a short screen recording. Put the file in `website/static/media/`, reference it from the blog post, and reuse it on the marketing pages where it fits.
-
-A release without a post and without clips is incomplete, in the same way a user-facing code change without a docs update is incomplete.
-
-## Clip conventions
-
-- MP4, H.264, no audio track unless the feature is about audio. Keep them short (10 to 30 seconds) and loopable.
-- Record the real thing. A clip from the engine's own benchmark suite or a real session, never a mockup.
-- Where the change is a speedup, record both sides on the same machine on the same input, so the comparison is honest.
-- Name the file after the feature, not the release (`vllm-race.mp4`, not `v4-8-demo.mp4`), so it stays reusable once the release is old.
-- The marketing site plays clips with `muted loop playsinline preload="none"` and a `data-lazy` attribute, which the site's IntersectionObserver uses to play and pause them on scroll. Follow that pattern for anything you add.
-
-## Order of work
-
-Label the PRs, generate and edit the release notes, cut the draft release, record the clips while the branch is still fresh in your head, then write the post against the notes and the clips. Publishing the release and merging the post should happen on the same day.
-
-The `creating-localai-releases` skill drives steps 1 to 3 and captures the React UI screenshots that go into the notes.

-## `Options[]` doubles as CLI-style engine flags

-Beyond the parser names above, `Options[]` carries `--` prefixed engine flags (`--enable-prefix-caching`, `--kv-cache-dtype:fp8_e5m2`). `apply_options_to_engine_args` in `backend/python/common/vllm_utils.py` maps them onto `AsyncEngineArgs` fields, and it must run **before** `AsyncLLMEngine.from_engine_args()` - applying them afterwards is a silent no-op, which is exactly what issue #11130 was.
-
-Things to keep straight when touching this:
-
-- Precedence is typed proto fields → `options:` → `engine_args:`. `applyEngineArgDefaults` in `core/config/hooks_vllm.go` therefore skips seeding a production default whose key the user already set as an option, otherwise the later `engine_args:` pass would silently override them.
-- Only `--` prefixed entries are engine flags; `tool_parser:`/`reasoning_parser:` and friends keep their meaning. Parser lookups accept both spellings via `normalize_option_key`.
-- Unknown or uncoercible flags warn and are skipped, unlike `engine_args:` which is strict - `Options[]` is a shared bag and knows entries this mapping doesn't.
-- Field types come from the annotation's *base* (`Literal["auto","float16"]` is not a float). The helper's tests are stdlib-only: `make test-python-helpers`.

+# Methodology: Closing the vLLM Decode-Throughput Gap in llama.cpp
+
+This is the playbook that took the paged backend
+([.agents/llama-cpp-localai-paged-backend.md](llama-cpp-localai-paged-backend.md))
+from ~38% of vLLM decode to **parity-to-ahead on dense** (and a proven, honest
+ceiling on MoE) on GB10. Use it for any "make llama.cpp match or beat engine X on
+accelerator Y" effort. The *levers* are model- and hardware-specific; the
+*discipline* below is not. The worked example, with all numbers, is the paged
+backend README.
+
+## The core loop
+
+1. **Establish a bit-exact baseline and gate FIRST.** Record the greedy md5 (per
+   path) and an f32 reference. Every optimization must stay byte-identical to it -
+   or ship as an explicit, default-off precision opt-in. This is what lets you
+   optimize aggressively without silently regressing quality. Gate two ways:
+   greedy md5, and `test-backend-ops` against the CPU oracle.
+
+2. **Profile - do not assume.** nsys the steady-state decode step, broken down per
+   *kernel* AND per *memcpy*. Find the dominant cost. "It's the GEMM" was wrong
+   here: on hybrid gated-DeltaNet models the bottleneck was the recurrent-state
+   **plumbing** (state memcpy + gathers, ~67% of the step), not the weight GEMM.
+   Also sanity-check GPU-busy %: an early "low utilization" reading was a profiling
+   window artifact (decode was 96-99% GPU-busy), not real idle.
+
+3. **Ground-truth BOTH engines.** Decompose *your* decode step AND the
+   competitor's, side by side, per bucket, and compute the per-bucket delta. This
+   tells you WHERE the gap actually is - not where you would guess. It overturned
+   premises here: e.g. vLLM does NOT run the GDN/attn projections as NVFP4 (it
+   keeps them bf16, same as us); the MoE expert GEMM was a llama *win*, not the gap.
+
+4. **Per-lever discipline.** For each candidate: implement -> bit-exact gate ->
+   same-harness A/B bench. Use a runtime env-toggle (flag off vs on) ONLY for
+   levers that are actually runtime-gated; a lever **compiled into** the binary
+   (e.g. the SSM decode fusions here) is NOT isolated by a runtime flag, so measure
+   it build-vs-build. The full-patchset "stock" baseline likewise needs a
+   **separately-built unpatched binary at the same pin** - toggling the runtime
+   flag on the patched binary does not reproduce stock (it measures only the gated
+   part; here that was ~neutral, which is exactly how this gotcha hides). Bank only
+   what lifts AND gates. **Record every rejected or flat lever with the reason** -
+   over time this is the most valuable part: it stops the next person re-running
+   dead ends.
+
+5. **Name the structural floor.** Prove the bit-exact ceiling exhaustively (every
+   lever measured, not assumed). What remains is physical - the memory-bandwidth
+   floor, the irreducible serial-SSM host loop (sampling can't start until logits
+   land). Name it; do not claim more than you measured.
+
+## Hard rules learned
+
+- **Apples-to-apples, or label it.** Stock-vs-patched on the SAME harness
+  (`llama-batched-bench`) is exact - lead with it. But "stock" must be a
+  separately-built unpatched binary at the SAME pin, NOT the patched binary with
+  the runtime flag off (compiled-in wins survive the toggle). Cross-engine "% of vLLM"
+  (batched-bench vs vLLM server+client) is *indicative*; always caveat the harness
+  and config (context length alone shifted the MoE figure 76% <-> 86%).
+- **Re-measure a "win" after later levers land - it may evaporate.** bf16 SSM
+  state (the `ssm_bf16_tau` lever) benched +12% early and failed the f32 KL gate
+  (vLLM keeps f32 too), so it was kept default-off opt-in. Once the decode fusions
+  (recurrent-state gather-fusion + block-table cache) landed, a clean re-measure
+  forcing ALL gated-DeltaNet heads to bf16 (`tau=100000`) went **flat** - 780.6 vs
+  780.0 t/s. The "+12%" was subsumed by the fusions: the lever bought nothing, so
+  it was **dropped** (precision trade + bug surface + extra CUDA template-instantiation
+  compile cost, zero benefit). A win measured before the rest of the series is not a
+  win after it.
+- **Reject the obvious-but-wrong, with evidence.** A faster kernel that is off the
+  critical path benches FLAT (the freed time becomes idle). Quantizing the bf16
+  projections to NVFP4 cost ~6% PPL - and vLLM keeps them bf16 for the same reason.
+  Always measure before believing; a plausible mechanism is not a result.
+- **The gate can be per-path.** Paged vs non-paged attention legitimately produces
+  different (equivalent) FP-reduction orders; validate the difference is benign
+  (KLD to f32) and then gate each path against its own reference.
+
+## Orchestration (multi-agent)
+
+- **One GPU profiler/bencher at a time** (the GPU-contention rule). Parallel
+  design/analysis/read agents are fine; concurrent GPU benches pollute each other's
+  numbers.
+- **Adversarial verify.** Before banking a finding, spawn skeptics prompted to
+  *refute* it; majority-refute kills it. Prevents plausible-but-wrong results.
+- **Anti-punt.** Use foreground, blocking ssh loops with short benches and a
+  progress-file checkpoint. Agents that background work and "wait for the monitor
+  event" stall - forbid that pattern.
+- **GPU coexistence.** On a shared host, stop the user's deployments for a clean
+  benchmark window (with their OK) and ALWAYS restore them (wrap the bench so a
+  failure cannot strand them).
+
+## What generalizes (and what doesn't)
+
+The *speedups* may be hardware-specific (here: CUDA/Blackwell - the SSM fusions,
+NVFP4 FP4-MMA, the occupancy tune), which is why other accelerators did not
+benefit. But the *findings* often generalize and are worth upstreaming: the
+"decode is plumbing-bound, not GEMM-bound" insight and the bit-exact, CPU-mirrored
+fusion ops help any backend running these models. Separate "ship our tuned backend"
+from "upstream the portable op" - they are different deliverables.
+
+## The closing record
+
+Write up the result HONESTLY: the shipped wins, the rejected levers (with reasons),
+the structural ceiling, and the cross-backend / cross-quant generality. Negative
+results are as valuable as wins. The paged backend README is the template.

-# apexentries
-
-Generates gallery entries for the `mudler/*-APEX-GGUF` HuggingFace repositories.
-
-Each APEX repo becomes one **family**: one entry per quality rung the repo
-publishes and one per quantization rung its unsloth counterpart publishes, all
-gathered under the **base model's** entry. LocalAI's variant selector then picks
-the build that fits the hardware in front of it.
-
-## The hub is the base model entry, never a generated `*-apex` parent
-
-Somebody looking for `qwen3.6-35b-a3b` must find every build of those weights
-under that one name: the APEX imatrix rungs, the unsloth quant rungs and any
-speculative build. A separate `qwen3.6-35b-a3b-apex` hub competing with the base
-entry would split the family in two and leave whichever half the user did not
-search for effectively invisible.
-
-So the generator resolves the hub by stripping the `-APEX`, `-MTP` and `-TQ`
-markers and looking the result up in the index, trying both the repo-derived and
-the stem-derived candidate the same way `CounterpartCandidates` does. Then:
-
-- **The hub exists** (14 of the 45 repos, resolving to 10 distinct entries).
-  Nothing new is emitted for the family root. A `variants:` block is spliced into
-  the entry that is already there, textually, leaving its description, icon,
-  tags, overrides and files untouched. The line editing is shared with the
-  `variantproposals` job via `.github/ci/galleryedit`.
-- **The hub is absent** (the other 31). A new hub is emitted, named for the base
-  model and never for the APEX repo. It carries one of the discovered builds as
-  its own payload so it is a complete installable entry rather than a bare index,
-  and that payload is what gives it an `overrides.backend`. Without a declared
-  backend the verifier would skip it, so a hub carrying feature tags would escape
-  the tagging check in silence.
-
-Several APEX repos routinely resolve to one base model, so both paths accumulate
-by hub name rather than assuming one family per hub.
-
-Two references are always filtered out of a hub's list: anything the entry
-already declares, and the hub's own name. The self reference is not merely
-redundant. An unsloth rung whose weights the gallery already ships under the base
-name resolves, through the merge, straight back to the hub, and the verifier
-reads a self reference as a variant that declares variants of its own.
-
-The four hand-written `*-apex` entries (`qwen3.6-35b-a3b-apex`,
-`gemma-4-26b-a4b-it-apex`, `qwen3.5-35b-a3b-apex`,
-`nemotron-3-nano-omni-30b-a3b-reasoning-apex`) are **ordinary builds**, not hubs.
-They are referenced from their hub's variants list like any other rung, and are
-never deleted or renamed.
-
-## Flags
-
-| Flag | Default | Meaning |
-|------|---------|---------|
-| `-index <path>` | `gallery/index.yaml` | Gallery index to dedup against. Read only, unless `-apply` is passed. |
-| `-only <a,b,c>` | (all) | Comma-separated full repo names (`mudler/Foo-APEX-GGUF`) to restrict generation to. A name that matches nothing is reported as a warning, since it is a typo rather than an empty result. |
-| `-out <path>` | (none) | Write the entries to add to this file. Nothing is written to the gallery. |
-| `-apply` | `false` | Splice the variants into `-index` and append the new entries to it. |
-| `-verify <path>` | (none) | Verify a gallery index and exit. Ignores every other flag. |
-
-Either `-out` or `-apply` is required, otherwise the run has nothing to do.
-
-`-apply` splices variant lines into existing entries and **appends** new ones. It
-never re-serialises the index: it is roughly 40,000 lines, and a YAML round trip
-would reflow the whole file, drop the anchors and merge keys the gallery relies
-on, and produce a diff nobody can review. On the three-family sample the splice
-is 24 added lines across 3 hunks with zero deletions.
-
-## Discovery is by filename suffix, never by repo name
-
-Builds come from the files a repo actually publishes. A filename is never
-constructed from a repo name, because the two disagree:
-`mudler/gemma-4-26B-A4B-it-APEX-GGUF` ships `gemma-4-26B-A4B-APEX-*.gguf`, and
-five other repos likewise drop a suffix (`-it`, `-2603`) or a vendor prefix
-(`NVIDIA-`) that the repo name carries. Composing a URL from the repo name would
-produce a 404 for every one of them, and the 404 would only surface after the
-entry shipped.
-
-The quality ladder is matched on the trailing tier marker, `-(I-)?(Quality|
-Balanced|Compact|Mini|Nano).gguf`. The `I-` prefix marks the imatrix ladder. The
-imatrix ladder is emitted when it is non-empty and the plain ladder is used only
-as a fallback, because two of the 45 repos publish no imatrix tiers at all and
-must still contribute. Eleven repos carry a fifth `I-Nano` rung, so nothing
-assumes a fixed number of rungs.
-
-Every run prints, per repo, the counts that discovery accounted for. If the
-number of classified files is short of the number of `.gguf` files the repo
-publishes, the shortfall is printed as `UNCLASSIFIED`. That check is a set
-difference on counts rather than a second pass over filenames: a second matcher
-would duplicate the tier regex and the two copies would drift. The failure it
-catches is quiet. A publishing-script typo that breaks every imatrix filename in
-a repo does not produce a short ladder; it makes the imatrix ladder empty, and
-the fallback then downgrades the whole family to the plain ladder with nothing
-said. A downstream HTTP check cannot catch it either, because it validates the
-URLs that were emitted, and an undiscovered tier emits none.
-
-The same reasoning applies to `UNACCOUNTED QUANT`, printed when the unsloth
-counterpart demonstrably publishes a wanted quant that produced no build. It is
-reported at discovery time because a dropped quant leaves no trace at all in the
-finished gallery file.
-
-## sha256 always comes from the API
-
-Every file stanza takes its `sha256` from the HuggingFace models API
-(`lfs.sha256`). A GGUF the API describes without one is a fatal error for that
-family: the repo is reported by name and the run ends non-zero. It is never
-substituted from another field, because that is exactly how a Xet hash ends up
-masquerading as a content hash.
-
-## The dflash / mtp tagging rule
-
-An entry is tagged `dflash` or `mtp` **if and only if** it configures the
-matching `spec_type:draft-<feature>`. Variant ranking reads tags and nothing
-else, so a tag that does not match the configuration either promotes a build
-that is no faster or hides one that genuinely is.
-
-A repo name is not configuration. `mudler/Qwen3.6-35B-A3B-APEX-MTP-GGUF` ships
-weights that carry MTP heads; an entry that does not enable them is not an MTP
-entry and is not tagged as one.
-
-A generated hub inherits the tags of the build it carries as its payload, rather
-than rebuilding them from the base set, so a hub whose payload configures a
-`spec_type` stays tagged consistently with the overrides copied alongside it.
-
-## Reuse reporting: two categories, not one
-
-Generated entries are deduped against the gallery and against the batch itself.
-The run prints the result under two separate headings, because the two cases are
-not equivalent:
-
-- **URI MATCHES** mean the gallery, or an earlier entry in this batch, already
-  ships exactly these weights. Pointing the hub at the existing entry is correct
-  and needs no thought.
-- **NAME COLLISIONS** mean an entry already owns the name but holds different
-  weights. Referencing it would point the hub at a build other than the one
-  generated. Every one of these must be inspected by hand.
-
-The run then prints `HUBS SPLICED`, listing every reference that will be added to
-an entry the gallery already ships along with the line it will be added at, and
-`HUBS CREATED` for the families that get a new hub. The splices are the part a
-review has to read closely, because they modify entries somebody else wrote.
-
-Hubs are deliberately kept out of the merge. A new hub carries the family's top
-rung as its own payload, so URI dedup would fold the hub into that rung and the
-family would lose the very entry point this command exists to create.
-
-## Workflow: sample first, then the full set
-
-Never run the full generation straight into the gallery. Generate a small,
-deliberately awkward sample, have it reviewed, then run the rest.
-
-```bash
-# 1. Sample three families that between them cover the awkward shapes:
-#    a standard four-rung repo, one with the extra I-Nano rung AND a file stem
-#    that differs from its repo name, and one whose unsloth counterpart shards
-#    its quants across subdirectories.
-go run ./.github/ci/apexentries \
-  -index gallery/index.yaml \
-  -only mudler/Qwen3.6-35B-A3B-APEX-GGUF,mudler/gemma-4-26B-A4B-it-APEX-GGUF,mudler/Step-3.7-Flash-APEX-GGUF \
-  -out /tmp/sample.yaml
-
-# 2. Verify the sample against the gallery it would join, splices included. Apply
-#    to a COPY, never to the real index, and check that the diff is only the
-#    intended variant lines. Compare the verifier output to the gallery's own
-#    baseline: what matters is that the sample adds no new problem, not that the
-#    total is zero.
-cp gallery/index.yaml /tmp/index-copy.yaml
-go run ./.github/ci/apexentries -index /tmp/index-copy.yaml -only <same list> -apply
-diff -u gallery/index.yaml /tmp/index-copy.yaml   # expect zero deletions
-
-go run ./.github/ci/apexentries -verify gallery/index.yaml > /tmp/baseline.log 2>&1
-go run ./.github/ci/apexentries -verify /tmp/index-copy.yaml > /tmp/spliced.log 2>&1
-diff /tmp/baseline.log /tmp/spliced.log
-
-# 3. Have a human review /tmp/sample.yaml and every reported name collision.
-
-# 4. Only then, the full set.
-go run ./.github/ci/apexentries -index gallery/index.yaml -apply
-```
-
-## Tests
-
-```bash
-go test ./.github/ci/apexentries/
-```
-
-The shared line editor has its own package:
-
-```bash
-go test ./.github/ci/galleryedit/
-```
-
-`.github/ci/` is invisible to `go list ./...`, so these specs are not covered by
-`make lint` or the repository test run. `.github/workflows/ci-tools-tests.yaml`
-names the package explicitly; keep that workflow in step with any package added
-under `.github/ci/`.

+# EARLY-WARNING CANARY for the vendored paged-attention patch series
+# (backend/cpp/llama-cpp-localai-paged/patches/paged/0001-0030).
+#
+# WHY THIS EXISTS
+# The paged backend (backend/cpp/llama-cpp-localai-paged) pins its OWN verified
+# llama.cpp tip (LLAMA_VERSION in backend/cpp/llama-cpp-localai-paged/Makefile)
+# and is intentionally EXCLUDED from the nightly auto-bumper
+# (.github/workflows/bump_deps.yaml), so a naive upstream bump can never silently
+# break the shipped build. The cost of that safety: nobody finds out when
+# upstream DRIFTS past the patches. This canary restores that signal WITHOUT
+# touching the shipped pin - weekly it tries the patch series + a real compile
+# against the LATEST llama.cpp master tip and goes red the moment upstream breaks
+# the patches.
+#
+# RED HERE means: time to run a PIN_SYNC (rebase the patches onto the new tip,
+# pass the bit-exact gate on the GPU, re-export the .patch files, THEN advance
+# the pin in backend/cpp/llama-cpp-localai-paged/Makefile). See the backend README
+# section 7 (Pin + maintenance policy):
+# backend/cpp/llama-cpp-localai-paged/README.md.
+#
+# SIGNAL-ONLY: this workflow moves no pinned version, ships nothing, and is fully
+# decoupled from bump_deps - so the main dep-bump PR stays green regardless. A
+# green run means "the paged series still applies and compiles on upstream HEAD";
+# a red run means "upstream moved - schedule a pin-sync".

-
-You do not need to be a large company, and you do not need to disclose anything

-## How to add yourself
-
-1. Add a row to the table, in alphabetical order.
-2. Use your organisation's usual name and a link to your site.
-3. Say briefly what you use LocalAI for, and whether it is in production.
-4. Open the pull request from an account that makes it plausible you speak for
-   the organisation, or say in the description who you are. We may ask.

-
-- **Engineers from these companies have contributed code.** Evidence is the

-  is a claim about a person, not about their employer.
-- **These projects integrate LocalAI.** Evidence is a reference to LocalAI in
-  that project's own repository or documentation.

-Those two lists live in [`website/data/ecosystem.yaml`](website/data/ecosystem.yaml).

 ## Quick Reference
 
-- **Coverage gates**: Never lower a coverage baseline or widen a gate's tolerance to turn a red gate green — the coverage ratchet only moves up. If a change drops coverage, add tests to raise it (e.g. render-smoke specs). See [.agents/building-and-testing.md](.agents/building-and-testing.md).
+- **Git hooks & coverage gates**: Run `make install-hooks` once per clone so the pre-commit lint + coverage gates run. **Never bypass them with `git commit --no-verify`, and never lower a coverage baseline or widen a gate's tolerance to turn a red gate green** — the coverage ratchet only moves up. If a change drops coverage, add tests to raise it (e.g. render-smoke specs). See [.agents/building-and-testing.md](.agents/building-and-testing.md).
 - **Logging**: Use `github.com/mudler/xlog` (same API as slog)
+- **Paged llama.cpp backend**: `llama-cpp-localai-paged` is a CUDA-only variant that owns its own patch series + its own pinned llama.cpp (manual pin-sync, weekly canary); the stock `llama-cpp` backend stays patch-free. Read [.agents/llama-cpp-localai-paged-backend.md](.agents/llama-cpp-localai-paged-backend.md) before touching either, and [.agents/vllm-parity-methodology.md](.agents/vllm-parity-methodology.md) for the decode-parity methodology behind it.
 - **Go style**: Prefer `any` over `interface{}`
 - **Comments**: Explain *why*, not *what*
-- **Docs (docs-with-code rule)**: When you change user-facing behavior (API endpoints, CLI flags, config keys, or features), update the corresponding page under `docs/content/` in the SAME change, not as a follow-up. A user-facing change without a matching docs update is incomplete. See also the documentation conventions in [.agents/coding-style.md](.agents/coding-style.md).
+- **Docs**: Update `docs/content/` when adding features or changing config
 - **New API endpoints**: LocalAI advertises its capability surface in several independent places — swagger `@Tags`, `/api/instructions` registry, auth `RouteFeatureRegistry`, React UI `capabilities.js`, docs. Read [.agents/api-endpoints-and-auth.md](.agents/api-endpoints-and-auth.md) and follow its checklist — missing any surface means clients, admins, and the UI won't know the endpoint exists.
 - **Admin endpoints → MCP tool**: every admin endpoint that an admin would manage conversationally (install/list/edit/toggle/upgrade) MUST also be exposed as an MCP tool in `pkg/mcp/localaitools/`. The LocalAI Assistant chat modality and the standalone `local-ai mcp-server` consume that package; drift between REST and MCP is a real risk. Read [.agents/localai-assistant-mcp.md](.agents/localai-assistant-mcp.md) — the `TestToolHTTPRouteMappingComplete` test fails until you wire the new tool and update the route map.
-- **Releases ship with a post and clips**: a release is not done at the tag. It needs labelled PRs, `RELEASE_NOTES_vX.Y.Z.md`, a blog post under `website/content/blog/`, and a short demo clip in `website/static/media/` for each notable feature. See [.agents/preparing-a-release.md](.agents/preparing-a-release.md).
 - **Build**: Inspect `Makefile` and `.github/workflows/` — ask the user before running long builds
 - **Backend OS coverage**: a new backend must target every OS it can build for, not just Linux. `.github/backend-matrix.yml` has two matrices — `include:` (Linux) and `includeDarwin:` (macOS / Apple Silicon). Most C/C++/GGML and many Python backends build on Darwin too — wire the `includeDarwin` entry + `backend/index.yaml` `metal:` entries, or say in the PR why an OS is unsupported. See the darwin checklist in [.agents/adding-backends.md](.agents/adding-backends.md).
-- **Gallery variant ranking**: a gallery entry can declare `variants` (alternative builds of the same weights), and LocalAI ranks the ones a host can run by engine preference first, size second. A new backend that should be preferred on some hardware must be listed in `engineNamePreferenceRules` in `pkg/system/capabilities.go`; the sibling `backendBuildTagPreferenceRules` speaks build tags rather than engine names, and using the wrong table matches nothing without erroring. See [.agents/adding-backends.md](.agents/adding-backends.md).
 - **UI**: The active UI is the React app in `core/http/react-ui/`. The older Alpine.js/HTML UI in `core/http/static/` is pending deprecation — all new UI work goes in the React UI

-The React UI (`core/http/react-ui/`) is covered by Playwright e2e specs, gated by a **monotonic line-coverage ratchet** (`make test-ui-coverage-check`, run in CI). The metric is non-deterministic — a fast local box reads higher than a slow CI runner for the same code — so a small tolerance is unavoidable.
+The React UI (`core/http/react-ui/`) is covered by Playwright e2e specs, gated by a **monotonic line-coverage ratchet** (`make test-ui-coverage-check`, run in CI and pre-commit). The metric is non-deterministic — a fast local box reads higher than a slow CI runner for the same code — so a small tolerance is unavoidable.
 
 **If your change lowers UI coverage, raise it back by adding specs — do not widen the tolerance or hand-lower the baseline.** A *render-smoke* spec (navigate to a page, assert its header is visible) cheaply covers an entire lazy page.

-# audio-cpp: 0xShug0/audio.cpp, a ggml audio inference framework covering TTS,
-# ASR, VAD, diarization, source separation and music generation, wrapped as a
-# LocalAI gRPC backend.
-#
-# BASE_IMAGE is ubuntu:24.04 for cpu and vulkan builds, or
-# nvidia/cuda:<ver>-devel-ubuntu24.04 for cublas builds; both ship apt and
-# Ubuntu Noble packages, and the CUDA base additionally provides
-# /usr/local/cuda. BUILD_TYPE selects the engine backend in the Makefile:
-# "" = portable CPU with all ggml CPU variants, "cublas" ->
-# -DENGINE_ENABLE_CUDA=ON, "vulkan" -> -DENGINE_ENABLE_VULKAN=ON. Darwin
-# (Metal) builds bypass this Dockerfile entirely.
-#
-# Upstream needs GCC 13 or newer, which ubuntu:24.04 and the CUDA 12/13
-# devel-ubuntu24.04 images all provide.
-#
-# THIS BACKEND CANNOT USE .docker/install-base-deps.sh OR THE PREBUILT
-# quay.io/go-skynet/ci-cache:base-grpc-* IMAGES, AND THAT IS NOT A STYLE CHOICE.
-#
-# Both supply gRPC v1.65 built from source at /opt/grpc, which downstream
-# Dockerfiles copy to /usr/local. That gRPC vendors protobuf v26, and protobuf
-# has depended on abseil since v22: google/protobuf/message_lite.h includes
-# absl/strings/cord.h. audio.cpp links sentencepiece, and our CMakeLists sets
-# SPM_PROTOBUF_PROVIDER=package so sentencepiece uses the same protobuf the
-# generated backend.pb.cc was built against (the alternative broke every
-# nested-message parse; the full account is in backend/cpp/audio-cpp/CMakeLists.txt).
-# That makes sentencepiece's init.h include the external message_lite.h while it
-# still includes its own vendored mini-abseil from third_party/absl. The vendored
-# copy declares `namespace absl { namespace internal { ... } }` and real abseil
-# declares `namespace absl { inline namespace lts_20240116 { namespace internal
-# { ... } } }`, so every `absl::internal::` reference becomes ambiguous and the
-# compile dies in absl/base/casts.h. Verified, not theorised: building this image
-# against the base-grpc-amd64 prebuilt fails at
-# sentencepiece-static/error.cc.o with "reference to 'internal' is ambiguous".
-#
-# Ubuntu Noble's apt protobuf is 3.21.12, which predates the abseil dependency,
-# so message_lite.h pulls in no abseil and the vendored copy is the only one in
-# scope. That is also the exact protobuf/gRPC pair every unit and end-to-end run
-# of this backend has been verified against. Keep it: a from-source gRPC here
-# does not buy a faster build, it buys a broken one.
-#
-# The install-base-deps path is additionally unsafe because it drops protoc 27.1
-# into /usr/local/bin, which shadows apt's protoc on PATH and would generate
-# protobuf-27 sources to be compiled against 3.21 headers.

-# TWO PROTOBUF RUNTIMES IN ONE BINARY, AND THE ONE THAT WON WAS THE WRONG ONE.
-#
-# engine_runtime links sentencepiece, whose default SPM_PROTOBUF_PROVIDER
-# ("internal") builds the protobuf-lite 3.14.0 sources vendored under
-# external/sentencepiece/third_party/protobuf-lite. Our generated backend.pb.cc
-# is compiled against the toolchain's protobuf 3.21.12 headers and links
-# libprotobuf.so 3.21.12. Both used to end up in the executable: 476
-# google::protobuf:: symbols from that archive, 278 of them also defined by
-# libprotobuf.so.
-#
-# The binding is decided at STATIC LINK time. Once ld pulls a sentencepiece
-# member in for sentencepiece's own code, that member's protobuf definitions are
-# in the executable and references from libhw_grpc_proto.a bind to them. Do NOT
-# reach for -Wl,--exclude-libs: it flips those symbols to LOCAL in .dynsym and
-# the breakage is unchanged, because no visibility flag revisits a static
-# binding already made.
-#
-# What broke, measured rather than assumed:
-# google::protobuf::internal::ParseContext::ParseMessage(MessageLite*, const char*)
-# is what every generated _InternalParse calls for a SUBMESSAGE field and for
-# nothing else. Bound to the 3.14 definition it fails, so a flat message parsed
-# and every nested one did not: a TranscriptResult carrying segments serialized
-# to correct bytes that the same process could not read back, and
-# TranscriptLiveRequest, a oneof of submessages, could not have been parsed at
-# all. 3.21 generated code was also running 3.14 arena, ArenaStringPtr and
-# ExtensionSet code, which is an ABI mismatch rather than a missing feature, so
-# "not observed to bite yet" was never a reason to leave it.
-#
-# "package" makes sentencepiece use the protobuf found above, which is the one
-# the generated code was built against. It must be set before add_subdirectory,
-# since that is when sentencepiece's own cache entry is created.
-#
-# WHAT THAT BUYS IS ONE PROTOBUF RUNTIME, not an executable free of protobuf
-# symbols, and the difference matters to whoever checks this next. Measured with
-# nm -C --defined-only on the linked grpc-server, 2515 google::protobuf::
-# symbols are still DEFINED in it, and that is what should be there: they are
-# generated code, sentencepiece::ModelProto's own _InternalParse and
-# CheckTypeAndMergeFrom among them, which name protobuf types in their
-# signatures and are compiled into every user of a .proto. Expecting zero would
-# send a reader looking for a regression that is not one.
-#
-# The claim that decides whether the ABI mismatch above is gone is the RUNTIME
-# one, and it holds: google::protobuf::internal::ParseContext::ParseMessage is
-# UNDEFINED in the executable, so every generated _InternalParse resolves it to
-# libprotobuf.so at load instead of to a vendored 3.14 copy. No vendored
-# protobuf-lite archive is pulled in at all, and citrinet_asr, which parses a
-# SentencePiece ModelProto at load, tokenizes correctly as a result.

-# does not rescue this: it list(APPEND)s in the ggml subdirectory scope, which
-# never reaches the root scope where the engine_runtime property is decided.
-#
-# The values below are ggml's list for the matching toolkit, copied rather than

-#   - CUDA 13 drops the Maxwell/Pascal/Volta virtual archs (50/61/70).
-#   - 121a-real needs CUDA >= 12.9, so the CUDA 12 list (built against 12.8)
-#     stops at 120a-real.
-#   - `a`-suffixed archs are used rather than ggml's rejected 120f-virtual: the
-#     `f` suffix needs CMake >= 3.31.8, and Ubuntu Noble ships 3.28.3. The

-#
-# An EMPTY major maps to `native`, NOT to the CUDA 12 list. Only CI declares a
