v1.8.0

Features

• Superscript / subscript — A new inline tool takes the tenth slot in the inline toolbar, bound to ⌘/Ctrl+Period and ⌘/Ctrl+Comma. The two modes are mutually exclusive, so applying one clears the other. Shipped with glyphs drawn into the shared inline-toolbar type system, translations in all 69 locales, and docs.
• Toolbox — Slash-menu entries are grouped under labeled sections, so a long tool list is scannable instead of a flat run of items. Each entry declares its own section.
• Tool contract — Blocks carry creation provenance (user/load/api/paste/convert/replay/probe), so a container can tell an author's gesture apart from a document load, a refetch or an undo replay. Enter's container-escape became a per-tool declaration instead of a hardcoded list of Blok's own tool names, so a custom container keeps Enter inside itself without an editor-global onEnter hook. insertInsideParent and BlockAPI.insertChild take an optional tool name, making an appended typed child one atomic operation and one undo entry.
• Framework adapters — The React, Vue and Angular block spec gained a general statics passthrough (toolbar anchor, ownsChildren, conversionConfig, the new Enter policy), an api handle, child-tree reactivity, per-child decoration, and an onMounted signal backed by a block:childrenMounted event. Handler presence is runtime-settable through api.handlers.set(), so passing onEnter at all no longer permanently decides Enter's semantics.
• Editor — A new opt-in captureClicksBelowEditor places the caret in the last block when the host clicks empty space below the editor. Off by default; registered as a config key in the React and Vue adapters too.
• Link — The link field sizes itself to its content, capped at the previous fixed width, and its create, error and edit states were polished.

Bug Fixes

• Nesting — setBlockParent no longer lets a container on the block's own ancestor or descendant chain veto a reparent; an enclosing container claiming a holder used to leave model and DOM permanently divergent (Enter inside a callout nested in another container), and a descendant doing the same nested every appended child inside its predecessor. mountChildBlocks now reclaims a holder stranded in any ancestor container, re-mounts it at its model position rather than last, and preserves the caret across the adoption. Depth indentation moved from an inline margin with a hardcoded exemption list to a depth multiplier resolved through --blok-block-indent-step, so a container tool declines the indent with ordinary CSS and no !important.
• Block API — Every handed-out BlockAPI is live, so getChildren() can no longer answer [] for a populated container and setParent/insertChild/moveChild can no longer silently no-op. api.blocks.update() prefers a tool's in-place setData when there are no tunes to apply, so it stops composing a replacement block that destroyed the previous one's portal and left the holder permanently empty.
• Inline toolbar — destroy() threw and aborted blok.destroy(), leaking listeners in every module torn down after it: hide() emits Closed synchronously, the handler then ran close(), which nulled the popover mid-teardown. The reference is now detached before hiding.
• Popover — Control-less HTML items (the new toolbox section headers) are no longer keyboard focus stops, so a role="presentation" header can't steal initial focus, shift every Arrow/Tab, or be pointed at by aria-activedescendant. Sibling active states refresh after an item is activated, and clicking the item that opened a popover now does nothing instead of reopening it.
• List — Tab/Shift+Tab moved the model but not the render: both handlers wrote depth into the tool's live data before calling api.blocks.update, whose in-place diff then saw no change, so save() and the DOM silently disagreed.
• Events and data — Keydown from a native form control a tool renders is no longer claimed by the editor. The toolbox merge and the save() extraction stop mutating tool-owned objects, so a toolbox entry carrying data no longer throws on a frozen save() result. A load is not an edit: a block arriving without a timestamp is no longer stamped at construction, so a save round-trip equals the document it came from.
• Adapters — The portal registries reject a teardown from a superseded instance, so a same-id re-register survives a late destroy; Vue additionally defined one wrapper component per tool type, so a re-register patched the superseded instance and rendered stale data — the wrapper is now per block instance. A React element toolbox icon serializes instead of rendering as [object Object], and the imperative handle keeps the controlled baseline in sync so restoring a draft after clear() is no longer swallowed as an echo.
• Styles — The icon stroke is scoped to Blok's own icon markup instead of every path in the subtree. The column floor moved to --blok-column-min-width in CSS, and the static-gutter attribute plus the block-padding tokens are now declared.

Maintenance

• Build — scripts/build-angular.mjs derived its adapters contract from a hand-copied list that silently drifted whenever a staged module gained an import; it now derives it from src/adapters.ts, and the staging law test walks the same graph so drift fails at test time instead of build time.
• Tests — 23 red e2e tests were root-caused rather than weakened: three were real product bugs (fixed above) and four were stale specs asserting behaviour that later commits deliberately changed. A leaked 600ms language-detection debounce in the code-tool unit tests was also cancelled, removing a load-dependent flake.
