Slate v2 Master Roadmap Consensus Plan

Supporting plan. For current queue and roadmap truth, see master-roadmap.md.

Problem Frame

The slate-v2 effort is currently split across:

• live verdict docs in docs/slate-v2/
• old roadmap and phase artifacts in docs/slate-v2/archive/
• active execution plans in docs/plans/
• separate docs/slate-browser/ north-star/testing docs
• a large evolving diff in /Users/zbeyens/git/slate-v2

That is too much surface for one migration program.

The user wants one canonical roadmap in docs/slate-v2/ that:

• is detailed enough to drive Ralph-sized work batches
• preserves migration obligations without regression theater
• folds slate-browser into the same vision
• carries reusable maintenance commands so this manual interview/planning pass does not need to happen again every time the repo shifts

RALPLAN-DR Summary

Principles

1. Migration-safe release truth beats roadmap archaeology.
2. Data-model-first core stays the top principle; React stays an optimization target, not the ontology.
3. Behavioral obligations matter more than preserving legacy file names.
4. The roadmap must be batch-oriented and execution-ready, not a pretty memo.
5. Maintainers need one canonical read plus one explicit diff/ledger story.

Decision Drivers

1. The current doc stack is too fragmented for reliable execution.
2. The testing/proof story only gets stronger if slate-browser is treated as a co-equal development lane, not a sidecar.
3. The roadmap needs built-in re-consolidation/re-interview/re-plan commands so future work can restart without another giant manual sync pass.

Viable Options

Option A: Keep docs/slate-v2 as live verdict only, keep roadmap machinery in docs/plans/

Pros:

• smallest doc rewrite
• least risk to current live verdict docs

Cons:

• keeps the real roadmap out of the place users want it
• preserves the split-brain problem
• forces maintainers to triangulate between verdict docs and plans forever

Option B: One master roadmap in docs/slate-v2/, supporting plans in docs/plans/, archive old roadmaps, fold slate-browser into the roadmap

Pros:

• matches the requested artifact ownership exactly
• gives one canonical roadmap while preserving supporting plans
• lets live verdict docs stay small and sharp
• makes slate-browser part of the migration path instead of a parallel doc sea

Cons:

• requires a careful archive move and cross-link cleanup
• requires explicit separation between roadmap truth and release-verdict truth

Option C: Merge everything into architecture-contract.md

Pros:

• one giant file
• minimal navigation cost

Cons:

• confuses architecture north star with release/migration execution
• makes current-vs-future truth too muddy
• directly conflicts with the user’s release-first boundary

Chosen Option

Pick Option B.

Why Option A Loses

It preserves the current “where the hell is the real roadmap?” problem.

Why Option C Loses

It would turn architecture-contract.md into a dumping ground and break the release-vs-north-star boundary.

ADR

Decision

Create one canonical batch-oriented master roadmap in docs/slate-v2/, archive older related roadmaps there, keep supporting execution plans in docs/plans/, and fold slate-browser into the same roadmap as the testing and proof-development lane.

Drivers

• reduce roadmap sprawl
• preserve live verdict doc clarity
• make future roadmap maintenance repeatable
• encode testing/proof strategy into the migration story instead of bolting it on later

Alternatives Considered

• keep roadmap ownership in docs/plans/
• collapse roadmap into architecture-contract.md

Why Chosen

It is the only option that:

• matches the requested artifact ownership
• keeps release truth and architecture north star separate
• gives Ralph/team a durable execution surface

Consequences

• docs/slate-v2/ gains one heavier canonical roadmap file
• archive curation becomes part of the work, not an afterthought
• docs/slate-browser/ stops acting like a parallel strategy universe
• the roadmap must be maintained actively at batch milestones

Follow-ups

• create the master roadmap
• create the commands pack
• create the review ledger
• archive older related roadmaps
• relabel architecture-contract.md truth classes

Implementation Units

Unit 1: Canonical Doc Ownership Reset

Purpose:

• define exactly which docs own:
  • live release verdict
  • master execution roadmap
  • architecture north star
  • archive/history

Files:

• /Users/zbeyens/git/plate-2/docs/slate-v2/overview.md
• /Users/zbeyens/git/plate-2/docs/slate-v2/archive/README.md
• new:
  • /Users/zbeyens/git/plate-2/docs/slate-v2/master-roadmap.md

Required decisions:

• overview.md stays the front door
• live verdict docs stay small
• master-roadmap.md becomes the only canonical roadmap in docs/slate-v2/
• master-roadmap.md is explicitly non-owner of stop/go release truth
• docs/plans/ becomes execution-record territory only:
  • batch-local execution records
  • investigations
  • audit ledgers
  • not queue/roadmap truth

Demotion protocol:

• every surviving doc in this explicit authority inventory:
  • docs/slate-v2/
  • docs/slate-v2/archive/
  • docs/plans/
  • docs/slate-browser/ must either:
  • move to archive
  • or carry a standard non-canonical banner:
    • Reference only. See master-roadmap.md for current queue and roadmap truth.

Disposition matrix:

• canonical live verdict docs:
  • no banner
  • examples:
    • overview.md
    • release-readiness-decision.md
    • replacement-family-ledger.md
    • full-replacement-blockers.md
    • replacement-gates-scoreboard.md
    • oracle-harvest-ledger.md
• canonical roadmap:
  • no banner
  • master-roadmap.md
• reference specs:
  • keep file
  • add/reference-spec banner if missing
  • examples:
    • architecture-contract.md
    • slate-batch-engine.md
    • chunking-review.md
• specialist lane docs:
  • keep file
  • require non-canonical specialist-lane banner
  • examples:
    • docs/slate-browser/*.md
• supporting plans:
  • keep only when still needed
  • require non-canonical supporting-plan banner if kept
  • scope:
    • docs/plans/*slate-v2*.md
• archive docs:
  • keep archive-only header
  • no queue/roadmap authority language

Authority inventory to sweep explicitly:

• active docs/slate-v2/ root docs:
  • slate-batch-engine.md
  • chunking-review.md
  • architecture-contract.md
• archive shadow owners already known:
  • archive/package-end-state-roadmap.md
  • archive/cohesive-program-plan.md
• every matching supporting plan file:
  • docs/plans/*slate-v2*.md
• specialist strategy docs under docs/slate-browser/

Naming rule:

• treat any file matching one of these as authority-inventory scope:
  • docs/slate-v2/*.md
  • docs/slate-v2/archive/*.md
  • docs/plans/*slate-v2*.md
  • docs/slate-browser/*.md

Banned ownership phrases outside master-roadmap.md:

• single source of truth
• owns .*queue
• owns .*roadmap
• active default queue
• operating .* roadmap
• this file wins for queue/next-slice ownership

Rule:

• inventory classification is the primary authority check
• phrase scan is a backstop for missed shadow-ownership language

Test scenarios:

• a reader can answer “where do I read the roadmap?” in one click
• overview.md clearly separates:
  • live verdict docs
  • master roadmap
  • reference specs
  • archive

Unit 2: Archive Move Plan

Purpose:

• move older related roadmap/phase artifacts out of the active lane

Likely archive candidates:

• prior roadmap/status/phase docs currently under /Users/zbeyens/git/plate-2/docs/slate-v2/archive/
• every docs/plans/*slate-v2*.md file that should not survive as an active supporting plan

Rules:

• do not delete historical docs if they still provide archaeology value
• do archive anything that competes with the new master roadmap
• if an authority-inventory doc survives outside archive, it must gain the standard non-canonical banner

Concrete shadow-owner targets to neutralize:

• docs/slate-v2/archive/package-end-state-roadmap.md
• docs/slate-v2/archive/cohesive-program-plan.md
• every matching docs/plans/*slate-v2*.md file
• any docs/slate-browser/*.md file that still reads as a strategy owner

Test scenarios:

• no older roadmap file in docs/slate-v2/ competes with master-roadmap.md
• archive docs are visibly labeled historical/reference only
• surviving authority-inventory docs outside archive are visibly demoted
• every matching docs/plans/*slate-v2*.md file is either archived or carries the standard non-canonical banner
• every authority-inventory file lands in exactly one disposition-matrix class
• banned ownership phrases are removed or replaced everywhere outside master-roadmap.md

Unit 3: Master Roadmap Authoring

Purpose:

• write the canonical roadmap itself

Target file:

• /Users/zbeyens/git/plate-2/docs/slate-v2/master-roadmap.md

Important scope rule:

• master-roadmap.md is canonical for:
  • batch order
  • milestone commands
  • current execution truth
• it should not duplicate every supporting proof/reference doc inline
• it should summarize and link when detail already lives better elsewhere

Required sections:

1. purpose and scope
2. north-star principles
3. release bar / non-regression rules
4. current status snapshot
5. ordered batch ladder
6. milestone command system
7. review-ledger protocol
8. architecture-contract alignment rules
9. slate-browser lane
10. release-candidate freeze protocol

Required batch shape:

Each batch must include:

• objective
• why now
• explicit entry conditions
• ordered substeps
• proof lanes
• rollback or branch decision point
• “if this changes the picture, run this command next”

Test scenarios:

• the roadmap is detailed enough to hand directly to Ralph without another full interview
• the roadmap is still readable as a single artifact

Unit 4: slate-browser Lane Consolidation

Purpose:

• fold docs/slate-browser/ into the same roadmap vision instead of leaving it as parallel strategy

Source inputs:

• /Users/zbeyens/git/plate-2/docs/slate-browser/overview.md
• /Users/zbeyens/git/plate-2/docs/slate-browser/proof-lane-matrix.md
• /Users/zbeyens/git/plate-2/docs/analysis/editor-architecture-candidates.md

Required output in the master roadmap:

• slate-browser as the testing/proof-development lane
• layered testing strategy:
  • core
  • dom
  • selection
  • browser e2e
  • IME/mobile
  • anchors
  • compatibility
  • performance
• explicit research hooks for difficult editor-testing problems using:
  • Lexical
  • edix
  • Premirror / Pretext
  • VS Code-style lane taxonomy where useful

Boundary:

• keep slate-browser as a linked specialist lane
• do not force every docs/slate-browser/*.md file to move immediately if that would just recreate a second doc churn wave

Important consolidation rule:

• first consolidate by shared vision and explicit links
• do not force every docs/slate-browser/*.md file to move immediately if that would just create churn without better ownership

Test scenarios:

• the roadmap makes it obvious when work belongs to slate-browser
• browser/mobile/editor-proof difficulty is treated as first-class planning input, not ad hoc debugging
• docs/slate-browser/overview.md no longer reads like a competing roadmap owner

Unit 5: Architecture-Contract Alignment Plan

Purpose:

• push architecture-contract.md as far as possible without turning it into the live ship gate

Files:

• /Users/zbeyens/git/plate-2/docs/slate-v2/references/architecture-contract.md
• /Users/zbeyens/git/plate-2/docs/slate-v2/master-roadmap.md

Required decisions:

• label major contract sections as:
  • current invariant
  • near-term required
  • future direction
• bake Ian’s feedback into the principles stack:
  • data-model-first
  • transaction-first
  • React-optimized runtime
  • not React-first ontology

Test scenarios:

• the roadmap references architecture-contract.md as canonical architecture map
• the contract no longer blurs current truth with future direction
• labels are applied at section/subsection grain, not sentence-by-sentence

Unit 6: File-Level Review Ledger

Purpose:

• make granular review durable and batch-friendly

Target file:

• /Users/zbeyens/git/plate-2/docs/slate-v2/release-file-review-ledger.md

Scope rule:

• every major changed/deleted file bucket must be represented
• every release-relevant file or file family gets an explicit checkbox row
• use family/file buckets where one row can honestly represent one decision
• do not preserve permanent checkbox noise for fully-settled trivial rows

Timing rule:

1. update at Ralph batch exit
2. update at roadmap reconsolidation milestones
3. full pass at release-candidate freeze

Required row fields:

• file or file family
• release relevance
• current disposition
  • preserved
  • adapted
  • replaced
  • explicitly dropped
• proof owner
• docs owner
• maintainer note
• [ ] / [x] state

Test scenarios:

• maintainers can tell what was reviewed and what still is not
• the ledger does not devolve into fake “all done” noise

Unit 7: Commands Pack

Purpose:

• kill the need for another huge manual coordination pass next time

Target directory:

• /Users/zbeyens/git/plate-2/docs/slate-v2/commands/

Required command docs:

1. reconsolidate-roadmap.md
2. refresh-file-review-ledger.md
3. reinterview-remaining-scope.md
4. replan-remaining-work.md
5. launch-next-ralph-batch.md

Each command doc should include:

• when to run it
• exact invocation pattern
• required inputs
• expected outputs
• what docs/files must be refreshed afterward

Rule:

• commands should document existing command graph and refresh loops where possible
• do not invent new ceremony when an existing command already earns the job
• one stable schema so the pack feels like a real operator surface, not random notes

Test scenarios:

• a maintainer can resume the roadmap without repeating the original interview
• command docs point to the correct canonical artifacts

Unit 8: Batch Ladder Design

Purpose:

• turn the current giant migration sea into a finite Ralph-friendly sequence

Required roadmap batch types:

1. contract and doc authority batch
2. testing/proof infrastructure batch
3. core oracle/parity batch
4. family-proof depth batches
5. maintainer/diff/migration-story batch
6. release-candidate freeze batch

Rules:

• batches should be large enough for Ralph
• not so large they blur objective/proof/rollback boundaries
• include agile flex points for unpredictable discoveries

Test scenarios:

• the batch ladder is detailed enough to staff directly
• the roadmap can absorb changed facts without collapsing

Unit 9: Milestone Command System

Purpose:

• encode recovery loops into the roadmap itself

Required milestone triggers:

• after any batch that changes the public claim
• after any batch that changes proof ownership
• after any batch that changes command graph or release gate
• after any batch that reclassifies architecture-contract sections

Required outputs:

• when to run re-consolidation
• when to re-interview
• when to re-plan
• when to launch next Ralph batch
• when to escalate to team mode

Test scenarios:

• no future maintainer needs to improvise the workflow from scratch

Deliberate-Mode Pre-Mortem

Scenario 1: Master Roadmap Becomes Another Bloated Graveyard

Failure:

• the new roadmap tries to contain everything and becomes unreadable

Prevention:

• keep verdict docs separate
• keep architecture contract separate
• use the roadmap for execution truth only
• push archaeology into archive

Scenario 4: Shadow Authority Survives The Rewrite

Failure:

• old docs keep ownership language after master-roadmap.md lands
• readers still find two or three docs that all claim to own the queue

Prevention:

• enforce the authority inventory sweep
• enforce the standard non-canonical banner
• grep for banned ownership phrases across:
  • docs/slate-v2/
  • docs/plans/
  • docs/slate-browser/

Scenario 2: slate-browser Gets Folded In Superficially

Failure:

• the roadmap mentions slate-browser but still plans migration as if browser proof were an afterthought

Prevention:

• require a dedicated slate-browser lane section
• require testing-framework research hooks in the roadmap
• require batch/proof mapping against the proof-lane matrix

Scenario 3: Granular Review Turns Into Bureaucratic Sludge

Failure:

• the ledger tracks every file forever and nobody updates it honestly

Prevention:

• represent every major bucket
• represent every release-relevant file/family
• allow one row to carry one real architectural decision
• enforce updates only at batch exit, reconsolidation, and release freeze

Team Verification Path

Before calling the roadmap work complete:

1. verify one canonical roadmap exists in docs/slate-v2/
2. verify older related roadmap docs are archived or clearly demoted
3. verify slate-browser appears as a co-equal roadmap lane
4. verify architecture-contract.md labeling rules are reflected in the roadmap
5. verify release-file-review-ledger.md exists and is usable
6. verify docs/slate-v2/commands/ exists with the required command docs
7. verify overview.md points cleanly to the new roadmap and archive

Concrete Verification Steps

Minimum same-turn evidence:

1. markdown formatting passes on all touched docs
2. cross-link grep confirms the new canonical file paths
3. repo-wide grep for competing authority phrases is clean or explicitly explained
4. overview.md gives a one-click path to master-roadmap.md instead of sending roadmap readers into plans
5. archive/readme pointers are consistent
6. roadmap, ledger, and commands docs all exist
7. each command doc includes a real runnable invocation
8. architect review approves
9. critic approves

Required grep scope:

• /Users/zbeyens/git/plate-2/docs/slate-v2
• /Users/zbeyens/git/plate-2/docs/plans/*slate-v2*
• /Users/zbeyens/git/plate-2/docs/slate-browser

Required phrase scan:

• single source of truth
• owns .*queue
• owns .*roadmap
• active default queue
• operating .* roadmap
• this file wins

Required inventory verification:

• list every file matching:
  • docs/slate-v2/*.md
  • docs/slate-v2/archive/*.md
  • docs/plans/*slate-v2*.md
  • docs/slate-browser/*.md
• confirm each matching file is one of:
  • canonical live verdict doc
  • canonical master roadmap
  • reference spec
  • archived historical doc
  • specialist lane doc with banner
  • supporting plan with banner
