# OVP Milestone

> Language: English | [简体中文](MILESTONE.zh-CN.md)

**Updated:** 2026-05-03
**Status:** Current milestone sequence and implementation direction

This document is the stable milestone entry point. It summarizes the current product and engineering route; [BACKLOG.md](BACKLOG.md) remains the single active implementation queue.

## Inputs

The milestone sequence is a reconciled view over:

- shipped repo milestone history and phase docs
- [Vision & Roadmap: The Auditable Knowledge Compiler](docs/plans/2026-04-22-vision-and-roadmap-trusted-reuse-compiler.md)
- recent KSR task extraction in `/Users/chris/Documents/ovp-vault/30-Projects/Active/OVP-Knowledge-State-Runtime.md`
- [reader-first product-shape research](docs/plans/2026-04-29-reader-product-shape-and-backlog-reconciliation.md)
- kg-eval quality assessment and `OVP_FIX_PLAN.md` (2026-05-01)

The KSR vault page is a high-signal recent input, not the complete backlog authority. Implementation sequencing is maintained in [BACKLOG.md](BACKLOG.md).

## Product Thesis

OVP is evolving from a personal Zettelkasten into:

> A typed, evidence-backed knowledge platform — reader-first for humans, programmable for agents, extensible through domain packs.

Three target tiers:

1. **Personal knowledge atlas** — Zettelkasten-quality with typed entities (current + M8)
2. **Company second brain** — pack-driven domain ontology, team-shared typed knowledge (M9)
3. **Operational knowledge layer** — Palantir-style actions, decisions, audit (M10, evaluate ROI)

## Current Milestones

## Near-Term Sequence

Recommended order:

1. **M8 first**: execute `BL-025` (type unification) → `BL-026` (extraction output) → `BL-027` (P3) → `BL-028` (P4) → `BL-029` (P5) → `BL-030` (backfill).
2. **M12 second** (parallelizable with M8 once entity layer is stable): execute `BL-038` (entity_aliases view) → `BL-039` (extraction-time entity prime) → `BL-040` (auto-wikilink). This is the loop closer for the entity work shipped in M11 — without it the entity layer stays "data on disk", with it new evergreens auto-link to canonical entities.
3. **M13 third** (after M12): `BL-041` (Louvain communities) → `BL-042` (Crystal MVP — community-clustered LLM synthesis) → `BL-043` (contradiction crystals) → `BL-044` (Crystal versioning). This adds the L3 synthesis layer OVP currently lacks (NM 0.8 has 240 crystals + community summaries; OVP has only the mechanical Atlas index).
4. **M9 then**: `BL-031` through `BL-034` once M8 type system is stable.
5. **M10 evaluate**: after M9 ships, decide scope based on real multi-pack adoption and company-brain use cases.
6. `BL-015` (permissions) when permission and claim lifecycle become the active blocker.
7. Keep workflow actions on the existing action worker lock; add generalized workflow leases only when multi-worker scheduling is introduced.

## Documentation Rules

- `README.zh-CN.md` is the Chinese README.
- `ARCHITECTURE.md` is the English primary architecture contract.
- `ARCHITECTURE.zh-CN.md` is the Chinese architecture contract.
- `MILESTONE.md` is the English primary milestone entry point.
- `MILESTONE.zh-CN.md` is the Chinese milestone entry point.
- [BACKLOG.md](BACKLOG.md) is the active implementation backlog source.
- Historical phase docs remain evidence and context, not active execution sources unless referenced by `BACKLOG.md`.
