+# Stepie / StepWise MCP — Ops Contract (SSOT)
+
+**Stepie plans. Monorepo ships. Dual-gate promotes.**
+
+Stepie AKA StepWise is an external planner (syworkshop.cn). Goal/step/matrix data live in their cloud only. This monorepo does **not** mirror Stepie rows into git as product SSOT.
+
+## Live MCP (operator)
+
+| Item | Value |
+|------|--------|
+| Product | StepWise / Stepie |
+| Vendor contact | support@syworkshop.cn |
+| MCP entry | https://stepwiseplanner.com/en-US/mcp/ (vendor-published) |
+| Connector (this agent) | `Stepie AKA: StepWise` |
+| Auth | Host/connector OAuth; no monorepo secret for default plan writes |
+
+Probe and tool schemas change on vendor side. Prefer live tool discovery over hardcoding.
+
+## Separation of planes
+
+| Plane | Owns | Does not |
+|-------|------|----------|
+| Stepie | Goals, steps, notes, matrix tasks, core memory | Merge PRs, Actions, code |
+| termux-monorepo | Code, workflows, docs, evidence, dual-gate | Invent Stepie completion |
+| LANE-MATRIX / Sweep | Board classification | Session-pulse PRs from Stepie |
+
+Policy one-liner (skill): Stepie must not emit session-pulse PRs or #175 comment floods.
+
+## Known failure modes (vendor + MCP)
+
+Observed 2026-09-22 … 2026-09-24 (operator email to support@syworkshop.cn + MCP writes):
+
+1. **Silent no-op create** — UI/MCP reports progress narrative; Goals / Steps / Tasks / Priority Matrix often do not materialize (partial success: one task).
+2. **Quota / Server Busy** — rapid `retry` on notification regeneration → quota message after create failures.
+3. **`update_step` Conflict** — matrixCategory (and other updates) require accurate `expectedUpdatedAt`; `search_step` may omit it → Conflict Exception when `null` is sent.
+4. **Memory restore** — prior-version memory recovery path unclear; open with vendor.
+
+Mitigations on our side:
+
+- After every write: re-`search_goal` / `search_step` / `search_task` and assert IDs exist before claiming success.
+- Do not spam retry; back off on quota.
+- For matrix updates: fetch a response that includes `updatedAt` before `update_step`, or set matrix in-app.
+- Keep durable product state in monorepo git; treat Stepie as planning surface only.

+## Live goals bound this cycle (2026-09-24 MCP)
+
+| ID | Title | Anchor | Notes |
+|----|--------|--------|-------|
+| **2157** | Custom Classifiers from Scratch | 10044 | Steps 10046–10050; note 1302 resources (Laya/Jev/sysone-bench) |
+| **2158** | Termux Orchestration Hub | 10045 | Steps 10051–10054; note 1303 hub_mcp / B160V envelope |
+| **2087** | termux-monorepo development | 9774 | Existing; primary product goal in Stepie |
+| **2149** | Games Masters … | 10007 | Primary goal; MoneyBall / classifier parity feeds 2157 |
+
+### Steps (2157)
+
+| ID | Title |
+|----|--------|
+| 10046 | Distill classifier spec from parity EVAL |
+| 10047 | Build training dataset pipeline |
+| 10048 | Train first from-scratch classifier |
+| 10049 | Optimize multi-environment builds |
+| 10050 | Run comparative classifier EVALS |
+
+### Steps (2158)
+
+| ID | Title |
+|----|--------|
+| 10051 | Map hub capability && capacity budget |
+| 10052 | Re-verify hub_mcp boundary docs |
+| 10053 | Wire hub dispatch to remote layers |
+| 10054 | Land local decision layer on device |
+
+### Open tasks
+
+| ID | Title | Matrix |
+|----|--------|--------|
+| 1223 | Verify TYPESAFE_API_KEY in GH Environment secrets | urgent_important |
+| 1224 | Locate awesome-list curation paths for Stepie handoff | not_urgent_important |
+| 1222 | Support ticket: export prior Stepie data for reintegration | not_urgent_important |
+
+## Execution layers (planning context)
+
+Actions, CodeSpaces, Environments, Colab, Render; future GCP/AWS/Azure free-tier research lane. Device hub = constrained (BLU B160V); heavy work remote.
+
+## Agent rules
+
+1. Create/update Stepie only when the operator explicitly authorizes a write.
+2. After write: verify by search; never claim success from narrative alone.
+3. Do not open session-pulse or heartbeat PRs from Stepie activity.
+4. Product code for classifiers / hub lives in monorepo PRs under dual-gate — not in Stepie notes.
