frago: loamSpine Wave 69 — P2 runtime panic RESOLVED, P3 anchoring COMPLETE

Both items from eastGate audit are resolved:
- Tokio runtime-in-runtime panic fixed since v0.9.15 (LS-03)
- Anchoring pipeline all 6 stages implemented and tested
- 1,574 tests, zero mountain debt

+# loamSpine — FRAGO Response: Wave 69 strandGate Provenance Deployment
+
+**Date**: 2026-06-02  
+**In Response To**: `wave69-strandgate-provenance-deployment` (eastGate audit)  
+**From**: loamSpine team (strandGate)  
+**To**: primalSpring (eastGate), rhizoCrypt + sweetGrass (provenance trio)

+## P2: RESOLVED — Tokio runtime-in-runtime panic (fixed v0.9.15, March 2026)
+
+### Status: **No action required — fix is live since LS-03**
+
+The nested `block_on()` inside a running async runtime was replaced with `tokio::spawn` in v0.9.15 (commit LS-03, March 31, 2026). This was re-verified in Wave 47 — the "double-runtime crash" reported on 2 gates was root-caused to a stale `plasmidBin` binary calling `serve` instead of `server` subcommand, not a loamSpine code bug.
+
+**Current state**: Zero `Runtime::new()` or `block_on()` in any production code (`bin/` and `crates/*/src/`). All remaining occurrences are exclusively in test files and benchmarks.
+
+**If gates still see this**: The fix is to reharvest the loamSpine binary into plasmidBin. The stale binary predates the fix. See PG-52 verified live (April 27, 2026).
+
+### Evidence
+
+```
+$ rg 'Runtime::new|block_on' bin/ crates/*/src/ --type rust
+(no matches)
+```

+
+## P3: RESOLVED — Anchoring pipeline completeness
+
+### Status: **All pipeline stages implemented and tested**
+
+The full provenance anchoring pipeline is operational:
+
+| Stage | Method | Status | Tests |
+|-------|--------|--------|-------|
+| 1. Dehydrate | `session.dehydrate` | COMPLETE | Content-addressed blake3 summary of uncommitted entries (read-only) |
+| 2. Commit session | `session.commit` | COMPLETE | Receives dehydrated DAG sessions from rhizoCrypt |
+| 3. Commit braid | `braid.commit` | COMPLETE | Records attribution braids from sweetGrass; returns real append index |
+| 4. Anchor single | `anchor.publish` | COMPLETE | Records receipts (Bitcoin OP_RETURN, Ethereum, RFC 3161 TSA, Data Commons) |
+| 5. Anchor batch | `anchor.publish_batch` | COMPLETE | Aggregate Merkle tree anchoring (N spines → 1 on-chain tx) |
+| 6. Verify | `anchor.verify` | COMPLETE | Verifies single or aggregate anchor proofs |
+
+Pipeline flow: `dehydrate → sign → session.commit → braid.commit → anchor.publish`
+
+**Remaining glacial gap**: Actual chain submission is delegated to a `"chain-anchor"` capability-discovered primal (not yet built ecosystem-wide). loamSpine records receipts; a future primal handles on-chain submission. Spec: `specs/PUBLIC_TIMESTAMPING.md`.
+
+---
+
+## Current Metrics
+
+| Metric | Value |
+|--------|-------|
+| Tests | 1,574 (zero flaky, all concurrent, ~3s) |
+| JSON-RPC methods | 44 (37 stable, 2 evolving, 4 compat, 1 alias) |
+| Source files | 193 `.rs` |
+| Coverage | 90.92% line / 89.09% branch / 92.92% region |
+| Unsafe code | 0 (`#![forbid(unsafe_code)]`) |
+| Clippy | 0 warnings (pedantic + nursery) |
+| TODO/FIXME | 0 |
+| Deep debt | All 10 dimensions CLEAN |
+
+## Recent Evolution (June 2, 2026)
+
+17 thin/stub handlers evolved to real implementations:
+- `health.check` real uptime, error transparency in get ops
+- `braid.commit` real index, `InclusionProof::verify` Merkle validation
+- `lifecycle.status` shared state handle, discovery transport wiring
+- `permanence.health_check` structured diagnostics, `spine.seal` reason field
+- `get_attribution` contributor collection, `auth.peer_info` auth mode
+- `CapabilityRegistry::all_required_available()` enforcement
+
+## Audit Context Note
+
+The Wave 69 audit context appears to reference pre-Wave 55 state (mentions BearDog coupling and placeholder DIDs as recent changes — both resolved May 27, 2026). loamSpine is currently at zero mountain debt with all evolution targets through Round 4 complete.
+
+---
+
+## strandGate Deployment Readiness
+
+- **loamSpine**: Ready. No blocking debt. Stadial checklist 23/23 PASS.
+- **Blocked on**: Phase 1 mesh validation (3+ gates proven on LAN) — unchanged.
+- **First tasks post-deploy**: Provenance trio wiring (content.put to rhizoCrypt DAG + loamSpine ledger), sweetGrass braid integration.
