Slate v2 Test Candidate Map: 5912-5771

Scope

These TDD handoff notes cover issues #5912 through #5771 from the pilot set. Use the top-level index for range navigation and the dossiers for fuller thread context.

Issue #5912

package: cross-package
TDD readiness: not-a-test-candidate
public test seam: WeChat Browser composition

Why Not A Direct Test Candidate

This is currently a browser-support boundary question, not a clean Slate-owned regression.

Issue #5895

package: ecosystem
TDD readiness: not-a-test-candidate
public test seam: none

Why Not A Direct Test Candidate

The thread treats this as consumer/plugin behavior rather than a promised Slate default.

Issue #5894

package: ecosystem
TDD readiness: not-a-test-candidate
public test seam: none

Why Not A Direct Test Candidate

The thread already lands on plugin/presentation solutions and does not point to a live core regression.

Issue #5891

package: slate-dom and slate-react
TDD readiness: ready-with-minor-setup
public test seam: Android first-line autocorrect

Minimal Repro Setup

empty editor with placeholder state
Android autocorrect-capable harness
first word that should autocorrect on space

Expected Failing Assertion

first-line autocorrect should apply when moving from empty editor state into content

Issue #5883

package: slate-dom and slate-react
TDD readiness: ready-with-minor-setup
public test seam: Android IME composition in empty leaves

Minimal Repro Setup

empty text node or mark-created empty leaf
Android IME composition path

Expected Failing Assertion

composition should remain active across the second character in an empty leaf

Issue #5874

package: slate and slate-dom
TDD readiness: ready-now
public test seam: duplicate node insertion by object identity

Minimal Repro Setup

one node object inserted into the document twice
follow-up edit or focus on the first copy

Expected Failing Assertion

Slate should fail with an intentional guardrail or otherwise avoid DOM/tree desync

Issue #5867

package: slate-dom and slate-react
TDD readiness: ready-now
public test seam: DOMEditor.focus with selected inline void

Minimal Repro Setup

mention or inline void selected
explicit DOMEditor.focus(editor) call

Expected Failing Assertion

focus should preserve the current logical selection instead of jumping to the start

Issue #5847

package: slate and slate-react
TDD readiness: ready-with-minor-setup
public test seam: triple-click hanging range delete

Minimal Repro Setup

Chrome or Safari
triple-click selection over a block

Expected Failing Assertion

backspace or cut should remove the entire block where that browser normally creates a hanging range

Issue #5844

package: docs-only
TDD readiness: not-a-test-candidate
public test seam: none

Why Not A Direct Test Candidate

This is mentions example UX, not core editor behavior.

Issue #5839

package: slate-dom and slate-react
TDD readiness: blocked-on-repro
public test seam: Safari last-block cursor alignment

Current Blocker

The issue is too thin. We need better steps than a video before writing a serious test.

Issue #5838

package: ecosystem
TDD readiness: not-a-test-candidate
public test seam: none

Why Not A Direct Test Candidate

This is an announcement, not an issue.

Issue #5836

package: slate-dom and slate-react
TDD readiness: ready-with-minor-setup
public test seam: Android repeated insert/remove same char

Minimal Repro Setup

Android editor
repeated insert_text/remove_text of the same character

Expected Failing Assertion

selection should not drift left under repeated same-character churn

Issue #5833

package: docs-only
TDD readiness: not-a-test-candidate
public test seam: none

Why Not A Direct Test Candidate

The thread resolves it as consumer rendering logic.

Issue #5830

package: slate-react
TDD readiness: ready-with-minor-setup
public test seam: composition onBlur on empty editor

Minimal Repro Setup

empty editor
composition-capable non-Latin input
move focus away mid-composition

Expected Failing Assertion

onBlur should still fire when focus is lost during composition

Issue #5826

package: slate-react
TDD readiness: ready-now
public test seam: refocus auto-scroll on long document

Minimal Repro Setup

long document
previous selection near the top
blur, scroll, click a new position, refocus

Expected Failing Assertion

refocus should not snap-scroll back toward the old selection

Issue #5824

package: ecosystem
TDD readiness: not-a-test-candidate
public test seam: iOS Notes rich paste

Why Not A Direct Test Candidate

This is parser capability scope, not a crisp Slate regression.

Issue #5820

package: docs-only
TDD readiness: not-a-test-candidate
public test seam: none

Why Not A Direct Test Candidate

The thread points at outdated or unsupported value-swapping patterns, not a live core bug.

Issue #5813

package: slate-react
TDD readiness: not-a-test-candidate
public test seam: paused rendering and decorators

Why Not A Direct Test Candidate

Debugger pause behavior is too underspecified and likely entangled with React/debugger semantics.

Issue #5811

package: slate
TDD readiness: ready-now
public test seam: custom normalize wrap/unwrap loop

Minimal Repro Setup

custom normalization that wraps in one direction
built-in normalization that unwraps the same shape

Expected Failing Assertion

normalization should not spin until the iteration guard trips

Issue #5806

package: slate-dom and slate-react
TDD readiness: ready-with-minor-setup
public test seam: drag selection over custom inline element

Minimal Repro Setup

custom inline element such as a button
drag-selection over it in the browser

Expected Failing Assertion

selection state should reflect the inline element instead of returning empty/null

Issue #5805

package: slate-dom and slate-react
TDD readiness: ready-with-minor-setup
public test seam: iPhone Safari Chinese IME in comments

Minimal Repro Setup

iPhone Safari or equivalent harness
Chinese IME composition in a comments-style editable

Expected Failing Assertion

direct IME input should work without the delete-composition workaround hack

Issue #5798

package: slate-react
TDD readiness: blocked-on-repro
public test seam: first-focus fast symbol insertion

Current Blocker

The issue body is too vague to turn into a trustworthy test.

Issue #5786

package: repo-only
TDD readiness: not-a-test-candidate
public test seam: none

Why Not A Direct Test Candidate

This is repo tooling debt.

Issue #5774

package: slate-react
TDD readiness: blocked-on-repro
public test seam: Vite HMR re-edit lockup

Current Blocker

It needs a cleaner minimal repro and current-version check before it becomes test work.

Issue #5771

package: slate and slate-react
TDD readiness: ready-with-minor-setup
public test seam: high-QPS remote insert_text versus local selection

Minimal Repro Setup

collaborative edit simulation
repeated remote insert_text at high rate
local selection attempt inside the same block

Expected Failing Assertion

remote edits should not steal or indefinitely expand the local selection unexpectedly
