MILAB-6810: migrate onto the structurer + add block kind

[AStaroverov]

Migrates the block onto the structurer and takes the full SDK upgrade that the require-latest CI gate forces.

What changed

SDK upgrade + structure refresh (fd1da35) — the canonical upgrade-sdk flow: block-tools 2.12.9 → 2.14.3, tengo-builder 4.0.20 → 4.0.23, model 1.83.0, ui-vue 1.83.3. The refresh reported 8 structural changes (kind configs, plus managed package.json across block/model/kind/workflow/software). structure check is now a fixpoint.

Block kind (4f49236) — the structurer hard-fails a kind-less block (declares no kind — every block must have a sibling kind/ package), so this adds kind/.

The init-params contract is inputAnchor + species: the two fields .args() requires, and the only ones a user sets by hand. Left out deliberately:

• datasetLabel — derived by the UI from the picked option's label, not user input.
• tableState / distributionGraphState — view state.

init now consumes params (every field keeping its default fallback, since a block may init without a template) and .templateParams projects the same two fields back, so export and apply stay inverses.

SPECIES_OPTIONS moves into the kind and is re-exported from the model — the kind cannot import from the model, and duplicating the list would let the contract and the UI dropdown drift apart.

Notes

• BlockParams.inputAnchor is declared string to match the model's BlockData, but the parser checks it with the SDK's isColumnUniversalId. Every value the picker can produce is a deriveColumnOptions id, so the stricter runtime check matches reachable states without pulling the UI's selectDataset into a retype.
• kind/ is private and never npm-published; its content reaches consumers through the kinds/ registry tree. model.json records …generation-probability.kind@1.0.0.

Verification

• pnpm build:dev-no-software — 12/12 green (model, ui, workflow, kind, block; type + lint + format checks included).
• block-tools structure check — up to date, 0 changes.
• Not run: workflow/integration tests against a live backend.

Greptile Summary

The PR upgrades the Platforma SDK and workspace structure, introduces the mandatory block-kind package, and adds a template initialization contract for dataset and species settings. It also refreshes package metadata and enables CI enforcement that changesets bump the published block package.

• Block kind — the typed identity and initialization contract for a category of blocks; added as a private workspace package with runtime validation for inputAnchor and species.
• Initialization parameters (BlockParams) — settings that templates can supply when creating a block; introduced with optional dataset-anchor and species fields.
• Template parameters — the projection of live block state used for template export; added to return the same inputAnchor and species consumed during initialization.
• Input anchor — the universal column identifier for the selected dataset; now accepted from initialization parameters and validated by isColumnUniversalId.
• Species — the generation-probability model selection (human or mouse); its options move into the kind package and are re-exported by the model.
• Block model — the durable state, workflow arguments, and derived outputs exposed to Platforma; now associates itself with the new kind and initializes configurable state from template parameters.
• Structurer — block-tools automation that normalizes package structure and dependencies; the workspace and managed manifests are refreshed for its current conventions.
• Changeset — release metadata describing package version changes; added for the block, model, workflow, and software packages.
• Package-path bump gate — CI validation requiring the published block package to receive a changeset bump; enabled in the reusable build workflow.

Confidence Score: 5/5

The PR appears safe to merge because no concrete blocking or independently actionable non-blocking defect was established.

The kind, model initialization, template projection, package graph, and release-gate changes are internally aligned, and the investigated packaging and identifier-validation concerns lacked a demonstrated reachable failure.

Important Files Changed

Filename	Overview

kind/package.json	Adds the private block-kind package and its build, check, export, and dependency configuration.
model/src/index.ts	Associates the model with the kind, initializes state from template parameters, and adds the inverse template projection.
block/package.json	Connects the kind package to the block’s workspace build graph while preserving the packaged component map.
.github/workflows/build.yaml	Enables changeset enforcement for the published block package.
pnpm-workspace.yaml	Registers the kind workspace and refreshes shared SDK and tooling catalog versions.
pnpm-lock.yaml	Locks the new kind dependency graph and the coordinated SDK/tooling upgrades.
