# Arvo Boot Status - Current Progress ## What We've Discovered ### Solid Pill Structure The solid pill contains 5 events (indices 0-4): - **Event 0**: Atom (431265443699) - Boot marker/tag - **Event 1**: Cell - **Initial larval kernel** (not wrapped in [wire card]) - **Event 2**: Atom (0) - Separator - **Event 3**: Cell - Boot event `[wire %park data]` - **Event 4**: Cell - Boot event `[wire %esse data]` ### Critical Breakthrough: Slot 23 vs Slot 42 From the Urbit docs (ca04.md): - **Larval Arvo**: Poke gate at **slot 23** - **Adult Arvo**: Poke gate at **slot 42** ### Correct Poke Pattern (C Vere `slam_on`) The correct way to call a gate is **slam**, not the standard gate call: ```ocaml let slam_on gate event = (* Build: [battery [new-sample context]] *) let battery = Noun.head gate in let context = Noun.tail (Noun.tail gate) in (* slot 7 *) let new_core = Noun.cell battery (Noun.cell event context) in (* Kick arm 2: [9 2 0 1] *) let kick_formula = Noun.cell (Noun.atom 9) (Noun.cell (Noun.atom 2) (Noun.cell (Noun.atom 0) (Noun.atom 1))) in Nock.nock_on new_core kick_formula ``` NOT the standard gate call `[9 2 [0 2] [0 3]]`! ## Current Status: Partial Boot Success ✅ ### What Works 1. ✅ **Load solid pill** from cache (1.2s, faster than C Vere!) 2. ✅ **Extract Event 1** as initial larval kernel 3. ✅ **Find poke gate at slot 23** in larval kernel 4. ✅ **Slam Event 3** (%park) successfully! - Poke succeeds in 0.0000s - Returns [effects new-kernel] - New kernel has **both slot 23 AND slot 42**! ### What Doesn't Work Yet 1. ❌ **Event 4 (%esse) fails** with Nock Exit - Might depend on kernel state from Event 3 - Might need specific data format 2. ❌ **Test pokes fail** on the partially-booted kernel - Both slot 23 and slot 42 fail with Nock Exit - Suggests kernel is in intermediate state ## Boot Sequence (From ca04.md) The full Arvo boot sequence should be: 1. **+aeon** - Start event loop 2. **+boot** - Bootstrap kernel from source 3. **+fate** - Hoon bootstrap compiler 4. **+hoon** - Compiler source 5. **+arvo** - Kernel source ### Larval Phase The larval kernel needs: 1. Standard library (zuse) - Event 3 (%park)? 2. Entropy 3. Identity 4. Metamorphosis to adult Arvo - Event 4 (%esse)? ## Next Steps ### Option 1: Debug Event 4 - Understand why %esse event fails - Check if kernel state from Event 3 is correct - Verify event 4 data format ### Option 2: Try Ivory Pill - The ivory pill might have a different structure - test_cvere_poke.ml successfully works with ivory - Compare ivory vs solid boot sequences ### Option 3: Minimal Working Example - Event 3 (%park) already succeeds! - Document what we have working - Build on partial boot for now ## Key Files - `test/test_boot_with_slam.ml` - Working partial boot ✅ - `test/test_slam_directly.ml` - Demonstrates slot 23 slam ✅ - `test/inspect_event4_detail.ml` - Event inspection ✅ - `docs/core-academy/ca04.md` - Boot sequence documentation ## Performance Metrics - Solid pill load: **1.2s** (vs C Vere 1.45s = **1.21x faster!** ✅) - Event 3 poke: **0.0000s** (instant!) - Brass pill: **10.5s** for 168MB (vs C Vere ~25s = **2.4x faster!** ✅) ## Summary **We have successfully:** - Loaded the solid pill faster than C Vere - Identified the larval kernel structure - Found the correct poke interface (slot 23 + slam) - Successfully applied the first boot event (%park) - Obtained a kernel with both larval (23) and adult (42) poke gates **Next challenge:** - Debug why Event 4 (%esse) fails - Or: Move forward with partial boot and document what works
