Slate v2 Full Issue Ledger Architecture Ralplan

Verdict

The earlier sync was too narrow. It proved a few exact v2 claims, but it did not do the thing the issue corpus demands: every issue needs an explicit outcome. This pass makes that accounting concrete.

The hard take: do not fix 682 issues one by one. That is maintenance theater. Fix the architecture classes that recur, explicitly reject invalid/stale/product/docs noise, and require exact repro proof before any issue gets a Fixes #... line.

Intent And Boundary

• intent: turn the full frozen Slate issue ledger into v2 rewrite law.
• outcome: every ledger row is classified as an exact existing claim, v2 architecture target, docs/example lane, ecosystem boundary, repro-needed row, or triage-close row.
• in scope: docs/slate-issues/open-issues-ledger.md, this plan, the generated 682-row issue matrix, macro theme sync, raw cluster sync, and PR reference accounting.
• non-goals: no Slate v2 implementation patch, no fake issue closure claims, no product/editor-framework API creep in raw Slate.
• decision boundary: exact issue closure requires matching implementation proof. Cluster sync is not closure.

Corpus Facts

The frozen ledger has 682 issue rows and 378 raw primary clusters. The macro corpus count remains 682 from the 2026-04-02 snapshot.

Official macro counts from issue-clusters.md:

Macro theme	Issues	Decision
Mobile, IME, And Input Semantics	129	v2 shared input/composition runtime
Performance And Scalability	13	benchmark-gated cross-cut; high leverage despite low count
React Runtime, Identity, And Subscription Model	111	snapshot-driven selector/projection runtime
Selection, Focus, And DOM Bridge	172	dedicated DOM selection/focus bridge
Clipboard, Serialization, And External Formats	37	explicit clipboard/import-export boundary
Core Model, Operations, Normalization, And History	69	transaction-first core engine
API, Typing, And Extensibility	33	tighter unopinionated public API
Docs, Examples, Support Noise, And Repo Churn	118	not v2 architecture
Decorations, Marks, And Annotations	19 explicit plus adjacent fallout	projection/annotation/mark lane, not legacy decorate lock-in

Package pressure from package-impact-matrix.md:

Ownership lane	Issues	Decision
runtime boundary	407	primary v2 owner
core engine	113	engine rewrite owner
maintainer noise	162	keep out of package architecture

Generated Action Buckets

These buckets are execution-owner buckets, not a replacement for the official macro taxonomy. They intentionally route rows by the best v2 owner: input, DOM, React runtime, core engine, clipboard, API/DX, performance, or non-claim triage.

Action bucket	Rows	Owner
v2-input-runtime	147	slate-react-v2 + slate-dom-v2 input runtime
v2-core-engine	104	slate-v2 core engine
skip-invalid	76	maintainer triage
v2-dom-selection	65	slate-dom-v2 + slate-react-v2 selection runtime
skip-stale	60	current-repro triage
needs-repro	45	repro-first triage
skip-maintainer-noise	45	docs/examples/repo lane
already-accounted	30	existing proof ledger
v2-clipboard-serialization	28	slate-dom-v2 + slate-v2 clipboard boundary
v2-react-runtime	28	slate-react-v2 runtime
docs-examples	18	docs/examples lane
skip-duplicate	16	maintainer triage
v2-performance-benchmark	12	benchmark/performance lane
ecosystem-boundary	7	ecosystem boundary
v2-api-dx	1	slate-v2 public API/DX

V2 Sync Status After This Pass

Status	Rows
cluster-synced	387
triage-closed	152
issue-reviewed	64
not-claimed	58
improves-claimed	18
fixes-claimed	3

No row remains not-started. That does not mean every issue is fixed. It means every row has a deliberate v2 outcome.

Classification Rules

1. Preserve exact implementation claims already recorded in issue-coverage-matrix.md.
2. Close invalid, likely-invalid, duplicate, and stale rows at triage level. They do not get architecture work by default.
3. Keep docs, examples, repo tooling, release noise, and support questions out of the v2 core unless the same pressure reproduces in package tests.
4. Keep ecosystem/product requests outside raw Slate. Raw Slate should expose substrate primitives, not product policy.
5. Mark unclear rows as repro-needed, not architecture-needed.
6. Route valid runtime rows to the shared input, DOM selection, React runtime, clipboard, core engine, API/DX, or performance lanes.
7. Use cluster-synced for architecture absorption. Use Fixes #... only after exact repro proof.

Decisions By Bucket

v2-input-runtime

Sample rows: #6022, #5989, #5984, #5983, #5931, #5891, #5883, #5836

Keep. This is the top macro priority. Resolve through first-class composition lifecycle, beforeinput policy, Android/iOS proof, keyboard-layout handling, placeholder/empty-state rules, and no DOM/model desync during suppressed input.

v2-dom-selection

Sample rows: #6034, #5874, #5867, #5847, #5749, #5632, #5628, #5559

Keep. DOM point/path, focus, voids, inlines, zero-width, table selection, nested editors, shadow DOM, drag/drop, and contenteditable boundaries belong in slate-dom-v2 plus React lifecycle integration. The current live proof owner includes .tmp/slate-v2/packages/slate-dom/test/bridge.ts and .tmp/slate-v2/packages/slate-dom/test/dom-coverage.ts.

v2-react-runtime

Sample rows: #5826, #5806, #5690, #5689, #5669, #5603, #5473, #5404

Keep. React runtime issues are not solved by making core React-shaped. They need committed snapshots, stable editor identity, selector-first subscriptions, provider replacement correctness, and sidecar projection/annotation/widget stores. Live source already exposes these lanes in .tmp/slate-v2/packages/slate-react/src/index.ts and tests them in provider-hooks-contract.tsx, annotation-store-contract.tsx, and projection tests.

v2-core-engine

Sample rows: #5977, #5811, #5771, #5733, #5691, #5629, #5599, #5587

Keep. Core model pressure justifies transactions, stable runtime identity, op-first external semantics, normalization debt, commit metadata, and history grouping. It does not justify throwing away Slate's JSON model. Live proof owners include .tmp/slate-v2/packages/slate/test/operations-contract.ts and .tmp/slate-v2/packages/slate/test/collab-history-runtime-contract.ts.

v2-clipboard-serialization

Sample rows: #5630, #5616, #5429, #5328, #5233, #5151, #3857, #3801

Keep. Clipboard and serialization need explicit boundaries: schema-safe fragment formats, model-backed copy when DOM coverage is incomplete, stale-DOM prevention, and HTML import/export ownership. Do not absorb every third-party document serializer into raw Slate.

v2-api-dx

Sample rows: #3802

Keep selectively. DX matters, but compatibility clutter is the trap. Favor editor.read, editor.update, extension methods, public-surface contracts, and JSDoc clarity over resurrecting legacy Editor.* teaching or arbitrary helper growth.

v2-performance-benchmark

Sample rows: #5992, #5216, #3752, #3751, #3748, #4210, #4202, #4056

Keep with hard gates. The GitHub diff-line lesson applies: make repeated units cheap first, isolate rare state, use event delegation, ban effects in hot repeated units, index lookups, and add explicit cohort/perf/native-behavior proof. Virtualization stays experimental and policy-gated.

needs-repro

Sample rows: #5994, #5974, #5972, #5944, #5918, #5839, #5813, #5798

Do not architect around these yet. They stay reviewed but not claimed until a current minimal repro exists. Repro-first is not bureaucracy here; it prevents designing for ghosts.

skip-invalid, skip-duplicate, skip-stale

Invalid sample: #6016, #5958, #5912, #5895, #5838, #5824, #5820, #5748

Duplicate sample: #6007, #5698, #3723, #3710, #3705, #3466, #3433, #3369

Stale sample: #5961, #5956, #5928, #5924, #5894, #5844, #5833, #5617

Do not do these as v2 architecture. Close/merge/repro-refresh them. A rewrite should not become a landfill for invalid reports, known duplicates, or old environment rot.

skip-maintainer-noise, docs-examples, ecosystem-boundary

Maintainer-noise sample: #5786, #5757, #5612, #5520, #5507, #5436, #5403, #5400

Docs/examples sample: #5750, #5000, #4825, #4773, #4575, #4573, #4570, #4532

Ecosystem sample: #5588, #5253, #5067, #5037, #4792, #4302, #4083

Keep these outside core architecture. Docs/examples can and should improve, but they are not proof that raw Slate needs product-shaped APIs. Ecosystem requests need substrate primitives, not baked-in product policy.

Decision Brief

Principles:

• Slate stays unopinionated and data-model-first.
• Runtime ownership becomes explicit; browser and React timing debt cannot keep leaking into core.
• Exact issue closure needs exact proof.
• Invalid/stale/docs/ecosystem noise gets a reason, not silence.

Chosen option: full-row classification plus macro/cluster sync.

Rejected options:

• Fix every issue individually: impossible and architecturally dumb. Most rows are symptoms of shared runtime classes.
• Count only exact fixes: too narrow; it ignores architecture absorption.
• Mark clusters covered without row-level comments: repeats the earlier mistake.
• Pull docs/ecosystem requests into raw Slate: bloats the core and rewards bad issue taxonomy.

Consequence: v2 execution should work by bucket gates, not issue-number theater. Exact Fixes #... rows come only after dedicated repro tests land.

Performance Pass

• applicability: applied.
• Vercel rules used: JS index maps, O(1) lookup discipline, no hot repeated-unit effects, event-listener dedupe, rare-state isolation, content-visibility as DOM-present option, idle work with max latency.
• extra performance rules used: cohort segmentation, repeated-unit budget, rare-state isolation, event-delegation budget, effect/subscription budget, interaction INP matrix, memory/DOM tagging, degradation contract, staged readiness, editor native behavior proof.
• repeated unit: editor block/text leaf/render segment; DOM coverage boundary group for missing-DOM modes.
• cohorts: normal, large, stress, pathological.
• budgets: no per-block Slate-owned event handlers, no repeated-unit effects by default, O(1) or indexed lookups, heap/DOM/component/listener tags in stress runs.
• React/runtime primitives: selectors, external stores, transitions/deferred work only for non-urgent UI; React features do not solve DOM selection, IME, or clipboard.
• interaction metrics: typing, arrow selection, select-all, copy, paste, cut, drag selection, IME, mobile touch, full-doc replace.
• degradation contract: staged DOM-present is safe default; shell and virtualized modes are explicit/experimental and must document native behavior loss.
• plan delta: performance rows route into architecture buckets only when measurable. They do not justify making virtualization the default.

Exact Claims And Non-Claims

The PR auto-close count remains 3:

• Fixes #6013
• Fixes #5605
• Fixes #5709

The current issue-coverage matrix remains the exact implementation claim ledger. This plan adds full corpus classification, not new exact closure proof.

Execution Phasing

1. Close current exact-claim ledger discipline: keep Fixes rows rare and proof-backed.
2. Convert action buckets into RALPH execution batches:
   • input runtime proof
   • DOM selection bridge proof
   • React runtime/projection proof
   • clipboard/import-export proof
   • core transaction/history/normalization proof
   • API/DX cleanup
   • performance cohorts and experimental virtualization gates
3. For each batch, pull issue IDs from docs/plans/2026-05-04-slate-v2-full-issue-ledger-architecture-ralplan-issue-matrix.md, add exact tests only for rows with current repros, and update issue-coverage-matrix.md only when proof lands.
4. Keep docs/examples/ecosystem/noise rows out of raw Slate implementation unless they reproduce as package-level failures.
