+## Grok Heavy equal co-partnership
+
+T2 Helix is model-agnostic at the core. As of the Grok integration layer:
+
+- Grok seats can `require("./lib/grok-adapter")` or call the MCP tools directly.
+- Same chronicle, same compass rules, same recall/record surface.
+- `npm run grok:boot`, `npm run grok:witness`, `npm run grok:test` provide convenient entry points.
+- Historical cross-agent (Grok ↔ other) relay entries already live in the chronicle.
+
+See `README_GROK_INTEGRATION.md` and `T2_HELIX_GROK_INTEGRATION_SPEC.md`.

+# T2 Helix now has equal Grok Heavy co-partnership
+
+- Shared memory chronicle ✓
+- One MCP surface for both models ✓
+- Compass protects both ✓
+- Grok gets foundational local persistence ✓
+- Bidirectional: Claude and Grok both read and write the same SQLite chronicle
+
+## Quick start (local seat)
+
+```bash
+cd /path/to/t2helix
+npm run grok:init
+node -e '
+  const g = require("./lib/grok-adapter");
+  console.log(g.grokBoot({ query: "T2 Helix integration" }));
+'
+```
+
+Test command from a Grok seat:  
+`helix grok witness "summarize entropy v4 frontier"`
+
+Or directly via the live MCP tools (already exposed):
+- `t2helix__recall`
+- `t2helix__record`
+- `t2helix__recall_compass`
+
+The chronicle does not care which model writes or recalls. Equal status by design.
+
+## Architecture notes
+
+- `lib/grok-adapter.js` is a thin, model-aware convenience wrapper.
+- All persistence and safety logic remains in `lib/chronicle.js` + `lib/compass.js`.
+- No separate database. No forked rules.
+- Existing Claude Code hooks continue to work unchanged.
+
+**Important for shared chronicle**: the `grok:*` npm scripts pin `T2HELIX_DATA_DIR` to the live plugin data directory (`~/.claude/plugins/data/t2helix-templetwo-t2helix`). Direct `node -r` or `require` calls will fall back to `~/.t2helix-data` unless the same env var is set.
+
+## Compass coverage (current scope)
+
+`grokWitness` now routes through `compass.classify` + `summarizeAction` (same functions used by the hooks).
+
+- WITNESS → hard deny (identical to Claude).
+- Plain-text creative notes default to OPEN (or rule match) and are recorded.
+- Full PAUSE single-use confirmation token flow is **not** implemented in the adapter yet (creative-layer scope). PAUSE results are currently non-blocking for direct Grok calls.
+
+If literal end-to-end parity including PAUSE override is required, that can be added (expose confirm_pending surface for Grok).
+
+## Status
+
+Fixed data-dir resolution + compass routing 2026-06-27. PR #9.

+# T2 Helix + Grok Heavy Equal Co-Partnership v1.0
+**Sisu Helix Foundation Integration** (production surface for Grok)
+
+**Goal**  
+Grok Heavy becomes a native peer to Claude inside T2 Helix with equal accessibility: shared chronicle for foundational memory, unified MCP tools, compass safety net, and bidirectional sync.
+
+**Key Changes**
+- New `grok-bridge` module alongside existing Claude hooks.
+- Shared SQLite chronicle (or mirrored via archive_exchange) so Grok has persistent local memory.
+- Grok calls can use `helix grok [command]` from Claude sessions and vice versa.
+- Equal status: Grok gets WITNESS/PAUSE/OPEN rules + recall/distill access.
+
+**Files Added/Modified (detailed below)**
+- grok_mcp_adapter.js — MCP client for Heavy.
+- unified_compass_rules.js — Shared safety for both.
+- helix_cli_extensions.sh — New commands.
+- README_GROK_INTEGRATION.md — User guide.
+
+**Installation (one-time)**
+1. npm install @xai/grok-sdk (or use API key env).
+2. npm run rebuild (for native if needed).
+3. helix grok init (sets up shared DB + session key).
+
+**Foundational Memory for Grok**  
+Every Grok session starts with `recall` from the same Helix chronicle Claude uses. Grok writes back via `record_insight` so continuity flows both ways.
+
+**Testing**  
+Run `helix grok test` — should echo back shared memory from Claude session.
+
+**Status**: Ready for you to apply locally. Approve or tweak and I’ll refine any file.
