release: prepare 0.29.0

Bump VERSION_NAME to 0.29.0 and prepare release notes.

- CHANGELOG: add [0.29.0] section (Minerva secure-MCU export module,
  packed-quant matmul kernels Q5_0/Q5_1/Q4_K/Q6_K with Native parity +
  Panama SIMD, auto-generated CI-gated kernel matrix, docs/tests/deps).
- README: bump BOM coordinate, rewrite "What's New" for 0.29.0, demote
  0.28.1 into Recent releases.
- docs: bump skainet-bom coordinates to 0.29.0 (io-readers,
  minerva-export, java-getting-started); regenerate kernel-support-matrix.

 ## [Unreleased]
 
+## [0.29.0] - 2026-06-09
+
+### Added
+
+- **Minerva secure-MCU export module.** A new export pipeline that takes a SKaiNET model all the way to a secure microcontroller project bundle, built up in phases:
+  - **Shared graph-export contracts.** A backend-agnostic export contract layer (`feat(export)`), with a StableHLO graph-export adapter that exposes the existing HLO path through those contracts. (#697, #698, #702)
+  - **Module API scaffold.** The Minerva export module's public API surface. (#700)
+  - **Phase-one graph-compatibility validation.** Validates that a graph is exportable before any lowering work begins. (#701)
+  - **IR lowering + npz compiler input.** Compatible graphs lower to Minerva IR (#704) and emit an `.npz` compiler input (#706).
+  - **Compiler packager + host verification.** A packager flow that drives libminerva packaging, plus a host-verification flow and runtime-verification profile that prove the exported bundle on the host before it ships. (#706, #712, #714, #716, #717, #721, #725)
+  - **Manifest fingerprinting.** Generated manifest artifacts are fingerprinted so bundle contents are tamper-evident. (#724)
+  - **Runnable sample + examples + docs.** A runnable sample task and runner, secure MCU export examples, an ONNX export workflow, getting-started / explanation pages, and model-source guidance. (#707, #712, #719, #725)
+- **Packed-quant matmul kernels with Kotlin/Native parity.** Q5_0, Q5_1, Q4_K, and Q6_K gain matmul support across the provider stack:
+  - **commonMain scalar kernels + SPI** for Q5_1/Q5_0/Q4_K/Q6_K, giving Kotlin/Native parity with the JVM path. (#710, #711)
+  - **Packed-quant matmul dispatch in `DefaultCpuOpsBase`** so the packed-quant path is selected on Native, not just JVM. (#709, #711)
+  - **Panama Vector (JVM SIMD) kernels** for Q5_1/Q5_0 (#709) and Q6_K, with Q6_K routed via the `KernelRegistry`. (#715, #720)
+  - **Packed Q5_1/Q5_0 matmul kernels + lazy transpose** on the CPU backend. (#709)
+
+### Changed
+
+- **Kernel × platform support matrix is auto-generated and CI-gated.** The kernel/platform support matrix is now rendered through the build-logic → Antora pipeline (the same pipeline as the ops docs) from a CI-gated source, so it can't drift from the code. (#716, #724)
+
+### Docs
+
+- Refreshed the architecture kernel-provider section (native FFM ships; link matrix). (#726)
+- Eager-execution backends & kernels mindmap, refreshed after Panama Q6_K. (#720, #723)
+
+### Tests
+
+- Hardened CI browser tests against launch flakiness under `allTests` (Karma) and raised the Mocha timeout 10s → 60s for the micrograd demo. (#703, #705)
+
+### Dependencies
+
+- Bumped `io.github.optimumcode:json-schema-validator` to 0.5.5. (#713)
+
 ## [0.28.1] - 2026-06-06

Shape-changing ops had been declaring a result/return type from operand-0 instead of their real output, so IREE rejected the modules. `inferDagOutputSpecs` now computes the correct output spec for `reshape`, `matmul`, `concatenate` (#673), and `conv1d`, `gather`, `maxpool2d`/`avgpool2d`, `flatten` (#675), and the corrected shapes flow to both the op result type and the `func.func` return.
-- **`reduce_window` (pooling) is emitted in IREE's generic region form** instead of the pretty `applies … over window` form IREE rejects; the `MlirValidator` now understands region block arguments. (#675, PR #676)

+- **Minerva secure-MCU export module.** A new end-to-end pipeline that lowers a SKaiNET model through shared graph-export contracts → Minerva IR → an `.npz` compiler input → a libminerva-packaged secure MCU project bundle, with host-side runtime verification and fingerprinted manifest artifacts. Ships with a runnable sample, secure-MCU export examples, an ONNX export workflow, and getting-started docs. (PRs #697–#726)

 ### Recent releases
 
+- **0.28.1** — Kotlin DSL → StableHLO → IREE is green end-to-end for the whole conformance suite (7/7 models, 27/27 ops compile to a `vmfb`): `inferDagOutputSpecs` now infers correct output shapes for shape-changing ops, and `reduce_window` (pooling) emits IREE's generic region form. (PRs #674, #676)
 - **0.28.0** — Four StableHLO export bugs fixed (reshape #666, concatenate #667, constants/reductions #663, `HloGenerator` tracing #668) plus non-JVM image runtime support (#671). (PRs #664, #670, #671)
 - **0.27.0** — A full gemma3 network lowers to StableHLO and compiles to an IREE `vmfb` (zero op gaps, verified by `GemmaTraceTest`): new `scaledDotProductAttention` (with causal + explicit additive mask), `permute`, `narrow`, and multi-output `split` converters, plus boxing-free `FloatArray` weight externalization for `.irpa` baking. (PRs #661 et al.)
 - **0.26.0** — Q4_0 promoted to a first-class quantized format across the provider stack, `tanh` as a first-class activation primitive, and a CPU tensor `convert` op, plus test/build/CI hygiene. (PRs #648–#651, #631, #636)

 Each cell is the best (highest-priority) provider that serves `Float32 × format` `matmul` on that platform: *native-ffm* (100) → *panama-vector* (50) → *scalar* (0). An empty cell (`—`) means no provider carries a kernel there (the format is dequant-to-FP32 only).
