Subject: [PATCH 05/19] ci: improve PR review workflows for ethlambda

- Extract shared review prompt to .github/prompts/pr_review.md
- Update all workflows to use consensus-layer terminology instead of execution-layer
- Add @chatgpt trigger to ChatGPT workflow (issue_comment + conditional)
- Add @kimi trigger to Kimi workflow (issue_comment + pull_request_review_comment + conditional)
- Pin ChatGPT action to specific commit (6fdbaeafc6f9e0eaebb844f8cfafff67cb2947f0)
- Replace ethrex references with ethlambda across all workflows
- Update Ethereum-specific considerations to focus on:
  * Fork choice (LMD GHOST / 3SF-mini) correctness
  * Attestation processing and validation
  * Justification and finalization logic
  * State transition functions (process_slots, process_block)
  * XMSS signature verification and aggregation
  * SSZ encoding/decoding correctness

+# ethlambda Development Guide
+
+Development reference for ethlambda - minimalist Lean Ethereum consensus client.
+Not to be confused with Ethereum consensus clients AKA Beacon Chain clients AKA Eth2 clients.
+
+## Quick Reference
+
+**Main branch:** `main`
+**Rust version:** 1.92.0 (edition 2024)
+**Test fixtures commit:** Check `LEAN_SPEC_COMMIT_HASH` in Makefile
+
+## Codebase Structure (10 crates)
+
+```
+bin/ethlambda/              # Entry point, CLI, orchestration
+crates/
+  blockchain/               # State machine actor (GenServer pattern)
+    ├─ src/lib.rs           # BlockChain actor, tick events, validator duties
+    ├─ src/store.rs         # Fork choice store, block/attestation processing
+    ├─ fork_choice/         # LMD GHOST implementation (3SF-mini)
+    └─ state_transition/    # STF: process_slots, process_block, attestations
+  common/
+    ├─ types/               # Core types (State, Block, Attestation, Checkpoint)
+    ├─ crypto/              # XMSS aggregation (leansig wrapper)
+    └─ metrics/             # Prometheus metrics
+  net/
+    ├─ p2p/                 # libp2p: gossipsub + req-resp (Status, BlocksByRoot)
+    └─ rpc/                 # Axum HTTP endpoints (/lean/v0/* and /metrics)
+  storage/                  # RocksDB backend, in-memory for tests
+```
+
+## Key Architecture Patterns
+
+### Actor Concurrency (spawned-concurrency)
+- **BlockChain**: Main state machine (GenServer pattern)
+- **P2P**: Network event loop with libp2p swarm
+- Communication via `mpsc::unbounded_channel`
+- Shared storage via `Arc<dyn StorageBackend>` (clone Store, share backend)
+
+### Tick-Based Validator Duties (4-second slots, 4 intervals per slot)
+```
+Interval 0: Proposer check → accept attestations → build/publish block
+Interval 1: Non-proposers produce attestations
+Interval 2: Safe target update (fork choice with 2/3 threshold)
+Interval 3: Accept accumulated attestations
+```
+
+### Attestation Pipeline
+```
+Gossip → Signature verification → new_attestations (pending)
+  ↓ (intervals 0/3)
+promote → known_attestations (fork choice active)
+  ↓
+Fork choice head update
+```
+
+### State Transition Phases
+1. **process_slots()**: Advance through empty slots, update historical roots
+2. **process_block()**: Validate header → process attestations → update justifications/finality
+3. **Justification**: 3SF-mini rules (delta ≤ 5 OR n² OR n(n+1))
+4. **Finalization**: Source with no unjustifiable gaps to target
+
+## Development Workflow
+
+### Before Committing
+```bash
+cargo fmt                                    # Format code
+make lint                                    # Clippy with -D warnings
+make test                                    # All tests + forkchoice (with skip-signature-verification)
+```
+
+### Common Operations
+```bash
+make run-devnet                              # Docker build → lean-quickstart local devnet
+rm -rf leanSpec && make leanSpec/fixtures    # Regenerate test fixtures (requires uv)
+```
+
+### Debugging
+
+<!-- TODO: fill this part after a debug session -->
+
+## Important Patterns & Idioms
+
+### Metrics (RAII Pattern)
+```rust
+// Timing guard automatically observes duration on drop
+let _timing = metrics::time_state_transition();
+```
+
+### Relative Indexing (justified_slots)
+```rust
+// Bounded storage: index relative to finalized_slot
+actual_slot = finalized_slot + 1 + relative_index
+// Helper ops in justified_slots_ops.rs
+```
+
+## Cryptography & Signatures
+
+**XMSS (eXtended Merkle Signature Scheme):**
+- Post-quantum signature scheme
+- 52-byte public keys, 3112-byte signatures
+- Epoch-based to prevent reuse
+- Aggregation via leanVM for efficiency
+
+**Signature Aggregation (Two-Phase):**
+1. **Gossip signatures**: Fresh XMSS from network → aggregate via leanVM
+2. **Fallback to proofs**: Reuse previous block proofs for missing validators
+
+## Networking (libp2p)
+
+### Protocols
+- **Transport**: QUIC over UDP (TLS 1.3)
+- **Gossipsub**: Blocks + Attestations (snappy raw compression)
+  - Topic: `/leanconsensus/{network}/{block|attestation}/ssz_snappy`
+  - Mesh size: 8 (6-12 bounds), heartbeat: 700ms
+- **Req/Resp**: Status, BlocksByRoot (snappy frame compression + varint length)
+
+### Retry Strategy on Block Requests
+- Exponential backoff: 10ms, 40ms, 160ms, 640ms, 2560ms
+- Max 5 attempts, random peer selection on retry
+
+### Message IDs
+- 20-byte truncated SHA256 of: domain (valid/invalid snappy) + topic + data
+
+## Configuration Files
+
+**Genesis:** `genesis.json` (JSON format, cross-client compatible)
+- `GENESIS_TIME`: Unix timestamp for slot 0
+- `GENESIS_VALIDATORS`: Array of 52-byte XMSS pubkeys (hex)
+
+**Validators:** JSON array of `{"pubkey": "...", "index": 0}`
+**Bootnodes:** ENR records (Base64-encoded, RLP decoded for QUIC port + secp256k1 pubkey)
+
+## Testing
+
+### Test Categories
+1. **Unit tests**: Embedded in source files
+2. **Spec tests**: From `leanSpec/fixtures/consensus/`
+   - `forkchoice_spectests.rs` (requires `skip-signature-verification`)
+   - `signature_spectests.rs`
+   - `stf_spectests.rs` (state transition)
+
+### Running Tests
+```bash
+cargo test --workspace --release                                    # All workspace tests
+cargo test -p ethlambda-blockchain --features skip-signature-verification --test forkchoice_spectests
+```
+
+## Common Gotchas
+
+### Signature Verification
+- Tests require `skip-signature-verification` feature for performance
+- Crypto tests marked `#[ignore]` (slow leanVM operations)
+
+### State Root Computation
+- Always computed via `tree_hash_root()` after full state transition
+- Must match proposer's pre-computed `block.state_root`
+
+### Finalization Checks
+- Use `original_finalized_slot` for justifiability checks during attestation processing
+- Finalization updates can occur mid-processing
+
+### `justified_slots` Window Shifting
+- Call `shift_window()` when finalization advances
+- Prunes justifications for now-finalized slots
+
+## External Dependencies
+
+**Critical:**
+- `leansig`: XMSS signatures (leanEthereum project)
+- `ethereum_ssz`: SSZ serialization
+- `tree_hash`: Merkle tree hashing
+- `spawned-concurrency`: Actor model
+- `libp2p`: P2P networking (custom LambdaClass fork)
+
+**Storage:**
+- `rocksdb`: Persistent backend
+- In-memory backend for tests
+
+## Resources
+
+**Specs:** `leanSpec/src/lean_spec/` (Python reference implementation)
+**Devnet:** `lean-quickstart` (github.com/blockblaz/lean-quickstart)
