+# Mainnet e2e on the Thunderbolt Mac mini — plan (2026-06-20)
+
+## Why this box (corrected target)
+NOT sp.reiers.io. The product thesis is "any-laptop SP on minimal HW."
+Target = Thunderbolt exo node `169.254.196.54` = Mac mini M4, 10-core, 16GB RAM,
+arm64, **351GB free**. SSH passwordless over Thunderbolt. Proving mainnet HERE
+is the demo + the beta gate in one. No jump host.
+
+## Proven READ-ONLY (zero spend, done)
+- Built native darwin/arm64 from HEAD 62e9a5f (v0.1.0-alpha.2+62e9a5f), 100MB, CGO-free.
+- Copied to node:/tmp/curio-core-mainnet, boots, shows `(alpha)`.
+- `probe --network mainnet` ANCHORED: epoch 6,121,440, state root resolved, clean shutdown.
+  => Embedded Lantern pulls mainnet chain truth on a 16GB Mac mini, no external full node. HARD PART DONE.
+
+## The gate (needs Nicklas — real FIL on mainnet)
+First mainnet e2e: register SP -> create dataset -> add 1 piece -> prove -> settle.
+Cost components:
+1. **SP registration fee = 5 FIL** (~$12-13) to ServiceProviderRegistry mainnet
+   `0xf55dDbf63F1b55c3F1D4FA7e339a68AB7b64A5eB`.
+   - OR reuse an existing mainnet SP registration if Nicklas holds one.
+2. **Gas** for create/add/prove/settle txs (small, FIL).
+3. **USDFC deposit** (small) to fund the payment rail.
+4. A **funded mainnet eth wallet** — curio-core mints a pdp-role key on first `run`;
+   Nicklas funds that address, OR imports a designated key via `wallet import`.
+
+## Exact sequence (when Nicklas says go)
+1. `run --network mainnet --data-dir <path> --no-public` (boot, mint pdp key, anchor).
+   - Pick data-dir on the 351GB volume; datapath auto-discovery available.
+2. Read pdp wallet address; Nicklas funds it (FIL + a little USDFC).
+3. `sp register --network mainnet --name ... --service-url ... --dry-run`  (inspect calldata, FREE)
+4. `sp register ... --submit`  (5 FIL) -> wait registry confirm.
+5. `demo create-dataset` -> `demo add-pieces` (1 small piece) -> proof loop fires -> `demo prepare-client-payments` / settle.
+6. Verify on-chain: dataset live, proof landed, rail settled. TAG v0.1.0-beta.
+
+## Honest residuals before a long mainnet SOAK (not blockers for the e2e)
+- stash-GC + stash-integrity (unfiled; the disk-full class). 351GB buys lots of runway but a true soak wants GC.
+- #50 bitswap block-path residual (bridge-off under load). e2e runs bridge-ON = safe.
