name: Session 2026-04-24 — META-DB v2.3 + Strategy Foundation
description: Major session establishing META-DB v2.3 (6-tier + 2-axis + visibility) + Tier 6 strategy (22 entries) + core value proposition + Mathlib outreach prep. Critical for next-session continuity.

**Session date**: 2026-04-24
**Duration**: ~full session, very substantive
**Key outcomes**: META-DB v2.3 foundational refactor + Rei-PL Prover v0.1 (STEP 997) + Tier 4/5/6 establishment + strategic positioning articulation

## Why this memory matters

This session crystalized the **core identity of Rei-AIOS** into an articulable elevator pitch AND built the META-DB infrastructure (Tier 4 gaps + Tier 5 tools + Tier 6 strategy) that operationally supports that identity. Future Claude sessions MUST know:

1. The core value proposition (exact wording)
2. META-DB v2.3 tier structure (6 tiers, not 3 or 4)
3. 2-axis classification (Missing × Executable → Q1-Q4)
4. Visibility flag system (public / semi-public / private)
5. 90-day action plan is queued for execution

## Core value proposition (MUST RECALL)

> **Rei-AIOS is the only operational database that continuously tracks (1) what existing technology lacks, (2) what is thought impossible, and (3) carries the capability to build what transcends both.**

日本語:
> **Rei-AIOS は、既存技術の不足 / 不可能と思われるもの / それを超える制作能力 — この三位一体を単一 DB 内で systematic に扱う、現時点で唯一の運用可能システムです。**

Source entry: `data/open-problems/rei-strategy/positioning/core-value-proposition-2026-04-24.json` (public visibility).

## META-DB v2.3 state snapshot

Total: **2,705 entries** across 6 tiers (commit `d359d62`):
- T1 world-public: 2,615
- T2 rei-inventions: 15
- T3 claude-discoveries: 8 (2 held-back for Paper 135/136)
- T4 gaps: 38 (ai 10 / math 7 / learning 5 / humanity 7 / consciousness 3 / rei-aios 6)
- T5 rei-tools: 7 (rei-pl-prover-v0_1 / invention-engine-v3 / nnue-dfumt / seed-kernel / compression-engine-suite / open-problems-metadb / cross-tier-dfumt8-analyzer)
- T6 rei-strategy: 22 (curriculum 4 / certification 4 / new-math 4 / monetization 6 / outreach 4 / positioning 1)

**Quadrant distribution** (missingExecutableMeta):
- Q1 (Missing+Executable = quick wins): 99
- Q2 (Missing+Impossible = frontier): 18
- Q3 (Present+Executable): 3
- Q4 (Present+Impossible = partial closures): 27
- untagged T1: 2,564

**Visibility distribution (T6)**: public 12 / semi-public 4 / private 6

## Schema extensions (v2.3)

1. `missingExecutableMeta` (on all Tier 2-6 + paperCandidate T1):
   - missingStatus / possibilityStatus / quadrant / missingKind / impossibilityEvidence / executabilityEffort
   - `superCapability.{builtTools, plannedTools, breakthroughNeeded}` (STEP 999c)

2. `visibilityMeta.publicVisibility` on Tier 6 ∈ {public, semi-public, private}

3. `toolMeta` on Tier 5 (version, phase, sourceCode, paperRef, toolCategory)

4. `strategyMeta` on Tier 6 (horizon, addressesGaps, dependsOnTools, reusableContexts)

5. `gapMeta` on Tier 4 (gapType GAP-A/B/C/M/P/S, gapSource claude/rei/fujimoto/world, severity, tractability)

## Auto-sync pipeline v2.3

`npm run publish:metadb` wraps:
1. `build-public-metadb-snapshot.ts` — respects visibilityMeta, filters Tier 6 by public flag
2. `build-public-metadb-manifest.ts` — recursive for gaps/ + rei-strategy/
3. `build-cfpages-metadb.ts` — CF Pages UI regen with Tier/Quadrant filters
4. patch index.html header count
5. git add/commit/push to rei-open-problems

Daily 14:10 JST auto-execution via `rei-learning-cycle.bat` Phase 8.

## Strategic docs (reference-only)

- `docs/internal-strategy-master-2026-04-24.md` (PRIVATE): Executive summary w/ elevator pitch + revenue model ranking + entity structure + 90-day plan + risks
- `docs/zulip-outreach-draft-2026-04-24.md` (semi-private): 2026-05-06 target Mathlib4 Zulip post draft + prereq checklist + response matrix

## Key build artifacts (Rei-PL Prover v0.1)

- `src/rei-pl-prover/` (160 LOC, 4 modules): types, checker, theorems, lean4-export
- `test/step997-rei-pl-prover-test.ts`: 16/16 tests pass
- `data/lean4-mathlib/CollatzRei/Step997ReiPLExport.lean`: lake env lean exit 0
- `prover.html` at rei-aios.pages.dev/prover.html
- `papers/paper-137-rei-pl-prover-v01-dfumt8-native.md` (draft, 298 lines)

## 90-day action plan (continues after 藤本 returns home)

| Week | Action | Owner |
|-|-|-|
| W1-2 | STEP 1000 "Mathlib Contribution Prep" — 5 artifact cleanup | Claude |
| W3 | Zulip post (2026-05-06 Tue target) | 藤本 |
| W4 | Commercial pitch deck draft | 藤本 + Claude |
| W5-6 | 合同会社 establish | 藤本 |
| W7-8 | NEDO proposal submit | 藤本 + Claude |
| W9-10 | Book pitch 3 publishers | 藤本 |
| W11-12 | Rei-PL Prover Phase 2 Mathlib translation prototype | Claude |

## How to apply in future sessions

1. **Session start**: read this file + `core-value-proposition-2026-04-24.json` to recall identity
2. **Any outreach / pitch draft**: quote the elevator pitch verbatim
3. **New entries**: choose appropriate Tier (1 for world-public, 2 for Rei invention, 3 for Claude discovery, 4 for gap, 5 for tool, 6 for strategy)
4. **Publish**: `npm run publish:metadb` is the single sync command
5. **CF Pages / GitHub Pages update**: automatic after commit push
6. **Next session resumption**: 藤本 returns home, continues from (AA) STEP 1000 or asks about other direction
