fak v0.56.0: Minor release for compute, model, ggufload, computetrace

This release contains 50 commits: 6 what changed changes, 14 reliability and correctness changes, 30 engineering quality and evidence changes. The sections below are grouped by operator impact, with the complete source history retained for auditability.

What changed

Security & Governance

• --dry-admit names what it does not check (load_fit not_run, advisory fit_warnings) and refuses a llama-mtp delegated serve, and bringup keeps device-only and the expert ring until it actually lifts a host refusal.
• Fak serve --execution-policy bringup admits host and offload execution on a bring-up-dedicated Halo, and --dry-admit runs admission alone, so device-only stays policy but never blocks the parity path.

Serving Engine, Gateway & Kernel Acceleration

• Fak model preflight lists every unread GGUF key, HF-config mismatch, missing/orphan tensor and dtype without a host kernel in one header-only pass.
• IQ4_NL routed experts stay raw-resident on the host GEMV, so Flash-Next's 43 IQ4_NL down_exps layers keep 0.5625 B/weight instead of the Q8 round trip.
• The GGUF loader admits qwen4exp with every key read, 34/34 keys matching the f5d0827 HF config and token ids matching dff6004, so Flash-Next geometry comes from the artifact, not constants.

Developer Platform, Tooling & Evidence

• Add per-arch llama.cpp stage maps, a public reference-oracle schema and a first-divergence verb, so any bring-up diffs layer by layer against its reference.

Reliability and correctness

Serving Engine, Gateway & Kernel Acceleration

• Bound automatic shared-ring request identity ledgers.
• File --expert-ring-bytes under the model help category, so fak serve help lists the V4.1 expert ring with its sibling expert flags.
• Fix direct auto ring resolver fraction parity.
• Make float array fallback explicit.
• Make preflight enum fallbacks explicit.
• Model preflight and new-model --gguf/--hf-config expand a leading ~ like every other user path flag.
• Retain canonical GGUF identity through JSON transport.
• Weakly key the V4.1 fault-ledger and Engram-stage registries, so a released model is collectable and internal/model stops OOM-killing the ci-fast runner.

Shared Trunk & Workspace Lifecycle

• Declare the vulkanregistry leaf lane and tree, so pkg/vulkanregistry resolves through explicit lane ownership.

Developer Platform, Tooling & Evidence

• Fence upstream issue citations by project name instead of a 10000 floor, so fak's own #13xxx refs count again.
• Add saturation for WSL retry durations.
• Declare the public reference oracle subtree.
• Fix installer PATH order and report siblings.
• Preserve recorder ownership and trace publication.

Engineering quality and evidence

Security & Governance

• Explain the pinned Unicode audit boundary.
• Extract Metal MTP receipt helpers below file ceiling.
• Restore the caller policy after compare benchmark.
• Merge upstream routed-expert batching and CI policy while preserving reviewed local fixes.
• Preserve upstream dry-admit refusal hardening.

Autonomous Agent & Multi-Model Harness

• Extract bounded prefill helpers.
• Extract native inference receipts.

Serving Engine, Gateway & Kernel Acceleration

• Batch each V4.1 decode layer's routed experts into one recorded device pass with a single status-and-sum readback, so a step submits 18 fewer times per layer.
• Borrow safe mapped expert checkpoint ranges.
• Characterize DS4.1 header padding roles.
• Extract CUDA tensor allocation helpers.
• Extract layer helpers below forward file ceiling.
• Extract Metal projection uploads below file ceiling.
• Extract saturating geometry helpers below file ceiling.
• Extract Vulkan dispatch geometry.
• Fix checkpoint HTTP fixture prompt encoding.
• Move Q2K fusion selection below the Vulkan file cap.
• Move V4.1 expert-ring pages into mapped GTT on a small-carve-out Halo, so the 64 GiB auto ring stops crashing and repeat decode runs 29-35% faster.
• Preserve upstream weak registry lifetime repair.
• V4.1 one-token decode kernels leave single-workgroup layouts, cutting the LM head 20x, mHC-mix matmul 8-30x and mHC rms-split 8x on device with every output bit unchanged.
• Preserve upstream reference and GGUF bring-up work.

Shared Trunk & Workspace Lifecycle

• Skip five pinned live-tree ratchets in the decisive ci-fast shards, so peer landings stop holding releases on repo-shape debt.

Developer Platform, Tooling & Evidence

• Add the change-detector test ratchet to the pinned non-decisive ci-fast list, so new peer tests stop reddening the release gate.
• Document fixed fixture and packed-format invariants.
• Fix pinned V14 registry fixture identity.
• Observe completed migration publication.
• Refresh generated command surface.
• Remove incidental live issue-reference requirement.
• Merge upstream admission and header diagnostics while preserving ring fixes.
• Preserve upstream ci-fast ratchet classification.
