The Licensee +(becoming Licensor) cannot offer or impose any additional terms or conditions on +the Work or Derivative Work that alter or restrict the terms of the Licence. + +Compatibility clause: If the Licensee Distributes or Communicates Derivative +Works or copies thereof based upon both the Work and another work licensed under +a Compatible Licence, this Distribution or Communication can be done under the +terms of this Compatible Licence. For the sake of this clause, ‘Compatible +Licence’ refers to the licences listed in the appendix attached to this Licence. +Should the Licensee's obligations under the Compatible Licence conflict with +his/her obligations under this Licence, the obligations of the Compatible +Licence shall prevail. + +Provision of Source Code: When distributing or communicating copies of the Work, +the Licensee will provide a machine-readable copy of the Source Code or indicate +a repository where this Source will be easily and freely available for as long +as the Licensee continues to distribute or communicate the Work. + +Legal Protection: This Licence does not grant permission to use the trade names, +trademarks, service marks, or names of the Licensor, except as required for +reasonable and customary use in describing the origin of the Work and +reproducing the content of the copyright notice. + +6.

Additional agreements + +While distributing the Work, You may choose to conclude an additional agreement, +defining obligations or services consistent with this Licence. However, if +accepting obligations, You may act only on your own behalf and on your sole +responsibility, not on behalf of the original Licensor or any other Contributor, +and only if You agree to indemnify, defend, and hold each Contributor harmless +for any liability incurred by, or claims asserted against such Contributor by +the fact You have accepted any warranty or additional liability. + +10.

Information to the public + +In case of any Distribution or Communication of the Work by means of electronic +communication by You (for example, by offering to download the Work from a +remote location) the distribution channel or media (for example, a website) must +at least provide to the public the information requested by the applicable law +regarding the Licensor, the Licence and the way it may be accessible, concluded, +stored and reproduced by the Licensee. + +12. Termination of the Licence + +The Licence and the rights granted hereunder will terminate automatically upon +any breach by the Licensee of the terms of the Licence. + +Such a termination will not terminate the licences of any person who has +received the Work from the Licensee under the Licence, provided such persons +remain in full compliance with the Licence. + +13. Miscellaneous + +Without prejudice of Article 9 above, the Licence represents the complete +agreement between the Parties as to the Work. + +If any provision of the Licence is invalid or unenforceable under applicable +law, this will not affect the validity or enforceability of the Licence as a +whole.

Note the `metallib:mlx` task **description** +string still says `build/dist/lib` — the actual `cp` target and the exported +`MLX_METALLIB_PATH` both use `build/dist/external/mlx.metallib`, and the embed +build reads both from `build/dist/lib/` (see below). If you script around these +paths, trust the commands, not the description string, and confirm on disk. + +## `task build` — the external-metallib binary + +```bash +task metallib # once, to produce the metallibs +task build # -> bin/lem +``` + +Builds `bin/lem` with `-tags metal_runtime -trimpath` and the darwin ldflags +(`-extldflags=-mmacosx-version-min=26.0`), using a dedicated build cache under +`/private/tmp/lem-dev/gocache`. This binary resolves its metallibs **externally** +at runtime via `MLX_METALLIB_PATH` (and the sibling lookup for +`lthn_kernels.metallib`), so `task metallib` must have run first. + +## `task build:embed` — the self-contained binary + +```bash +task metallib # once +task build:embed # -> bin/lem, SELF-CONTAINED +``` + +This is the "you only need go-inference" build. It: + +1.

Builds `bin/lem` with `-tags "metal_runtime embed_metallib"`. + +Under `-tags embed_metallib`, `go/cmd/lem/embed_metallib.go` is compiled in and +`//go:embed`s both gzipped libraries into the binary.

Both extract into the one dir + so the engine's sibling lookup finds `lthn_kernels.metallib` beside + `mlx.metallib`. +- Sets `MLX_METALLIB_PATH` at the extracted `mlx.metallib`. + +Extraction is idempotent (a present non-empty file is trusted) and writes via a +temp sibling + rename so a concurrent start never sees a half-written file. Any +failure is best-effort: it leaves `MLX_METALLIB_PATH` unset so the engine falls +back to normal external resolution rather than crashing at import time. + +The result runs **from any path** with nothing external to ship or resolve — the +single-artifact USP. The trade-off is size: the embedded `mlx.metallib.gz` alone +is ~47 MB, so the embed tag is deliberately kept out of routine `go build` / +`go test` / CI runs (without the tag, `embed_metallib.go` is excluded and the +engine resolves the metallib externally). + +## Runtime resolution recap + +| Build | How the metallib is found | +|-------|---------------------------| +| plain `go build` / `go test` | not embedded; `MLX_METALLIB_PATH` or a colocated `mlx.metallib`; `lthn_kernels.metallib` looked up as a sibling | +| `task build` (`metal_runtime`) | same external resolution; `task metallib` must have produced the libraries | +| `task build:embed` (`metal_runtime embed_metallib`) | libraries baked in, extracted to a content-addressed temp dir, `MLX_METALLIB_PATH` set before Metal init unless the operator set it first | + +The engine-side resolution (env var name `MLX_METALLIB_PATH`, the sibling +`lthn_kernels.metallib` lookup, the composed-primitive fallback) lives in +`go/engine/metal/device.go`. diff --git a/docs/cmd-lem.md b/docs/cmd-lem.md new file mode 100644 index 0000000..6c215f4 --- /dev/null +++ b/docs/cmd-lem.md @@ -0,0 +1,324 @@ +# The `lem` binary + +`lem` is Lethean's sovereign inference binary.

This helper clears the map and is defined in `inference_test.go`: - -```go -func resetBackends(t *testing.T) { - t.Helper() - backendsMu.Lock() - defer backendsMu.Unlock() - backends = map[string]Backend{} -} ``` -Because `resetBackends` is in the `inference` package (not `inference_test`), it has direct access to the unexported `backends` map. Tests must not rely on registration order across test functions; each test that uses the registry must call `resetBackends` at the top. - -### Stub Implementations - -`inference_test.go` provides `stubBackend` and `stubTextModel` — minimal implementations of `Backend` and `TextModel` for use in registry and routing tests. These are in the `inference` package itself (not a separate `_test` package) to allow access to unexported fields. - -When writing new tests, use the existing stubs rather than creating new ones unless you need behaviour the stubs do not support. - -### Table-Driven Tests - -Prefer table-driven tests for options and configuration variants. The existing `TestApplyGenerateOpts_Good`, `TestWithTemperature_Good`, and `TestDefault_Good_PriorityOrder` tests demonstrate the pattern: - -```go -tests := []struct { - name string - val float32 - want float32 -}{ - {"greedy", 0.0, 0.0}, - {"low", 0.3, 0.3}, -} -for _, tt := range tests { - t.Run(tt.name, func(t *testing.T) { - cfg := ApplyGenerateOpts([]GenerateOption{WithTemperature(tt.val)}) - assert.InDelta(t, tt.want, cfg.Temperature, 0.0001) - }) -} -``` - -### Assertions - -Use `testify/assert` and `testify/require`: - -- `require` for preconditions where failure makes subsequent assertions meaningless (e.g. `require.NoError(t, err)` before using the returned value) -- `assert` for all other checks -- `assert.InDelta` for float32/float64 comparisons (never `==`) - -## Coding Standards +## Go workspace -### Language +Development uses **workspace mode**. `go.work` at the repo root `use`s `./go`, +`./gui`, and every `external//go` submodule, so local edits to the core +dependencies are picked up without a `replace` directive.

Run `gofmt -w .` or `go fmt ./...` before committing. - -### Error Messages - -Error strings start with the package name and a colon, lowercase, no trailing period: - -```go -fmt.Errorf("inference: no backends registered (import a backend package)") -fmt.Errorf("inference: backend %q not registered", cfg.Backend) -fmt.Errorf("inference: backend %q not available on this hardware", cfg.Backend) -``` - -This convention matches the Go standard library and makes `errors.Is`/`errors.As` wrapping straightforward. - -### Strict Types - -All parameters and return types are explicitly typed. No `interface{}` or `any` outside of test helpers where unavoidable. - -### Dependencies - -No new external dependencies may be added to the production code. The `go.mod` `require` block must remain stdlib-only for non-test code. `testify` is the only permitted test dependency. - -If you find yourself wanting an external library, reconsider the approach.

Note: the agent loop does not yet honour context +cancellation, so `Stop` marks the runner stopped but the underlying loop is not +interrupted mid-flight (flagged in the code). + +#### DockerService + +Manages the LEM Docker Compose stack. `Start`/`Stop` shell out to +`docker compose -f /docker-compose.yml up -d` / `down` (via +`golang.org/x/sys/execabs`), with per-service start/stop/restart, `Logs`, and +`Pull`.

The draft proposes d0..d_{K-1}; each +// d_i is stepped on the TARGET to get hidden_i, and the target's greedy there is T_{i+1} = +// greedy(head(hidden_i)). Accept the longest prefix where d_i == T_i (i.e. the draft matched what +// the target would have emitted), then emit ONE bonus correction token T_j (the target's greedy at +// the first mismatch, or after a full-length accept) and step it. The cursor hidden h for the next +// round is the bonus token's hidden. Every emitted id is a target greedy id, so the stream equals +// target.Generate(promptIDs, maxNew, eos) token for token. +// +// Cache rollback on reject: the target steps all K draft tokens (advancing pos by K), then pos is +// reset to the accepted length + the committed bonus token. The rejected suffix's K/V rows are +// simply overwritten by the next write at that position (stepToken writes at pos and SDPA attends a +// pos+1 window — see decode_forward_arch.go), so resetting pos is a complete rollback. This is exact +// for owner caches. Sliding-ring/device-paged caches keep only the visible window; rollback stores +// the absolute offset separately and the batched bridge syncs the physical ring slots before and +// after verification, so a speculative window may straddle a ring wrap. + +// MTPResult reports a speculative decode: the generated ids (target-greedy, identical to plain +// Generate) plus the acceptance accounting — how many draft tokens were proposed vs accepted, and +// how many draft+verify rounds ran.

+Foundation for decode record/replay — the fix for the host-encode wall (~12ms/token, GPU 99.8% idle), validated externally by gemma E4B 100->500 tok/s on an A10 via CUDA graphs (the NVIDIA twin of Metal command-buffer replay). Records pipeline + buffer binds + inline bytes + threadgroup-mem + dispatch dims per command buffer via hooks in set_buffer/set_input_array/set_compute_pipeline_state/set_bytes/dispatch_*. Verified on 12B-4bit: decode steps are byte-structurally stable token-to-token (47 + 27/28 cmds repeating) — only buffer ADDRESSES churn, so replay pins the step's buffers. Zero cost when off.

+lthn_decode_finalize() stashes one decode step's recorded command stream; lthn_decode_replay(raw) re-issues it (pipeline/binds/bytes/tg-mem/dispatch + captured memoryBarriers) directly to the compute encoder, bypassing the MLX tape-walk + per-primitive eval_gpu (~12ms host/token). Guarded by lthn_decode_replaying so replay doesn't re-record. Not yet wired into the decode loop (needs buffer pinning + input/offset update + byte-exact gate). Dark by default (env MLX_DECODE_CAPTURE).

+MetalAllocator::lthn_pin_begin/release: while pinning, free() defers buffers (keeps them alive + same address) instead of recycling, so the recorded decode-step command stream — which references specific MTL::Buffer* — stays valid for verbatim replay. lthn_pin_release() frees them via the normal path. Driver entry points lthn_decode_pin_begin/release. Third of the three replay primitives (recorder, replay, pin); wiring into the decode loop is next.

+bytesHash (FNV over all inline setBytes payloads per CB) is IDENTICAL across decode tokens => RoPE offset etc. are buffer-driven, not baked host scalars; the two-update replay plan (input-token + offset buffer CONTENT) is sufficient. Also surfaced: decode = 2 CBs/token, a 47-cmd CB byte-identical every token + a small CB alternating 28/27 cmds every other token (intrinsic, present in serial too) — replay must record the cycle + alternate.

+A decode step spans 2 command buffers (47-cmd + 27/28-cmd cycle). lthn_decode_step_begin/end capture the whole step into lthn_step_program (a list of per-CB command streams in order), so replay can re-issue the full step, not a single CB. Compiles; driven via the upcoming replay-eval + decode-loop hook.

+lthn_decode_replay_step(s) re-issues the captured step program to the stream's encoder and commits per command buffer, bypassing the MLX tape-walk + eval_gpu. With the recorder, step-capture, and pin, the C++ replay machinery is complete; next is the cgo bridge + decode-loop hook to drive record-once / replay-rest with the input+offset buffer updates and a byte-exact gate.

+Two fixes made record/replay run on-GPU: (1) recording state is GLOBAL not thread_local (MLX encodes on the stream's thread, not the control thread that arms it); recording armed by capture-env OR programmatic step-capture. (2) replay enqueues onto the stream's scheduler thread (get_command_encoder is per-thread) and ensures that thread has an encoder via idempotent new_stream (Metal buffers are device-global). Verified: a tiny Add captured as a 2-CB step, pinned, replayed — byte-exact output, no MLX tape-walk.
