+# glamsterdam-devnet-6 Assertoor Playbooks
+
+These assertoor playbooks cover glamsterdam-devnet-6 (Amsterdam fork) behaviors that
+require a live running network and cannot be covered by EELS state/blockchain tests alone:
+cross-client consistency, CL/beacon API cross-validation, P2P protocol negotiation,
+multi-slot block accounting, and builder lifecycle flows.
+
+EVM semantics EIPs (7708, 8246, 8038, 7954, etc.) are covered by the EELS spec test
+suite (`glamsterdam-devnet-6-eels-tests.yaml`) rather than duplicated here.
+
+---
+
+## Playbook Index
+
+| Filename | EIP(s) | What requires a live network |
+|----------|--------|------------------------------|
+| `glamsterdam-devnet-6-eels-tests.yaml` | 2780, 7708, 7778, 7843, 7928, 7954, 7976, 7981, 7997, 8024, 8037, 8246, 8282 | Runs full EELS spec suite against the live EL client |
+| `glamsterdam-devnet-6-eip7778-block-gas.yaml` | EIP-7778 | Verifies `block.gasUsed` diverges from `sum(receipt.gasUsed)` when refund txs are present — requires real mined blocks across multiple slots |
+| `glamsterdam-devnet-6-eip7843-slotnum.yaml` | EIP-7843 | Cross-validates SLOTNUM opcode return value against the CL beacon API slot |
+| `glamsterdam-devnet-6-eip7928-bal-hash.yaml` | EIP-7928 | Reads `blockAccessListHash` from all EL clients simultaneously to verify cross-client consistency |
+| `glamsterdam-devnet-6-eip7975-8159-protocol.yaml` | EIP-7975/8159 | Verifies p2p protocol version negotiation via `admin_peers` — not testable in state tests |
+| `glamsterdam-devnet-6-builder-lifecycle.yaml` | EIP-8282 | Builder deposit/exit lifecycle requiring CL slot progression and `execution_requests` in beacon blocks |
+
+---
+
+## Dependencies
+
+### genesis-generator >= 6.1.0
+
+Required for `glamsterdam-devnet-6-eels-tests.yaml` and `glamsterdam-devnet-6-builder-lifecycle.yaml`.
+EIP-8282 needs the builder registry predeploy (`0x0000884d2AA32eAa155F59A2f24eFa73D9008282`) in genesis,
+which genesis-generator added in 6.1.0. If running on an older generator, skip the builder tests or
+run them only after verifying the predeploy exists.
+
+### Foundry (forge + cast)
+
+All playbooks that deploy or interact with contracts install foundry at runtime via `foundryup`.
+There is no pre-installed foundry requirement; each test that needs it installs and cleans up its own copy.
+An internet connection to `foundry.paradigm.xyz` is required during test execution.
+
+Playbooks that install foundry: `eip7954-initcode`, `eip7778-block-gas`, `eip8037-refund-routing`,
+`eip8038-gas-verify`, `eip8246-no-burn`, `builder-lifecycle`, `eip7981-access-list-gas`,
+`eip2780-intrinsic-gas`, `eels-tests` (indirectly via foundry steps).
+
+Playbooks that do NOT require foundry: `eip7997-factory`, `eip7843-slotnum`,
+`eip7928-bal-hash` (use eth_getBlockByNumber/eth_call via curl only),
+`eip8024-opcodes` (uses EELS for the suite; eth_call smoke test via curl).
+
+`eip7708-transfer-logs` installs foundry for Test 3 (deploys a Forwarder contract to
+verify internal CALL-with-value also emits Transfer logs). Tests 1 and 2 use curl only.
+
+---
+
+## Running Playbooks: Independent vs. Together
+
+### Run independently (self-contained)
+
+Each glamsterdam-devnet-6 EIP playbook is fully self-contained: it generates its own funded wallets,
+installs any tooling it needs, and cleans up after itself. They can be run in any order and in parallel.
+
+| Playbook | Can run in parallel? |
+|----------|---------------------|
+| `eip7708-transfer-logs` | Yes |
+| `eip7843-slotnum` | Yes (depends on EIP-7997 being live in genesis, not on the 7997 playbook) |
+| `eip7954-initcode` | Yes |
+| `eip7997-factory` | Yes |
+| `eip8024-opcodes` | Yes |
+| `eip7981-access-list-gas` | Yes |
+| `eip2780-intrinsic-gas` | Yes |
+| `eip7976-calldata-floor` | Yes |
+| `eip7778-block-gas` | Yes |
+| `eip7928-bal-hash` | Yes |
+| `eip8037-refund-routing` | Yes |
+| `eip8038-gas-verify` | Yes |
+| `eip8246-no-burn` | Yes |
+| `builder-lifecycle` | Yes, but waits for GLOAS fork epoch |
+
+### Run sequentially (ordering recommendation)
+
+If running the full suite manually, a natural order is:
+
+1. `eip7997-factory` — verifies the CREATE2 factory predeploy (other tests may use it)
+2. `eip7843-slotnum` — uses the factory internally
+3. `eip7708-transfer-logs`, `eip7954-initcode`, `eip8037-refund-routing`, `eip7778-block-gas`, `eip7928-bal-hash`, `eip8038-gas-verify`, `eip8246-no-burn`, `eip8024-opcodes`, `eip7981-access-list-gas`, `eip2780-intrinsic-gas`, `eip7976-calldata-floor` — in any order
+4. `builder-lifecycle` — last, since it waits for GLOAS epoch
+5. `glamsterdam-devnet-6-eels-tests` — runs the full EELS suite; takes up to 6 hours; run last or standalone
+
+### Legacy devnet playbooks
+
+`bal-devnet-3-eels-tests`, `bal-devnet-4-eels-tests`, `bal-devnet-4-eip8024-stack235-only`,
+and `bal-devnet-5-eels-tests` are for previous devnets and should not be run on glamsterdam-devnet-6
+(different fork config, different EIP set, pinned to incompatible spec branches).
+

+
+## EIP Reference
+
+| EIP | Title | Amsterdam change |
+|-----|-------|-----------------|
+| EIP-2780 | Reduce intrinsic transaction gas | TX_BASE=21000 unchanged; calldata token model (zero=4, nonzero=16 gas/byte) |
+| EIP-7708 | ETH transfer logs | `Transfer(from, to, value)` emitted by `0xfff...ffe` on every ETH move |
+| EIP-7843 | SLOTNUM opcode | New opcode `0x4b` pushes current beacon slot number |
+| EIP-7954 | Increase maximum contract sizes | MAX_CODE_SIZE 24576 → 65536; MAX_INIT_CODE_SIZE 49152 → 131072 |
+| EIP-7997 | Arachnid CREATE2 factory pre-deploy | Factory at `0x4e59b44847b379578588920ca78fbf26c0b4956c` in genesis |
+| EIP-8037 | Source-based gas refund routing | State-clearing refunds credited to tx.origin, not coinbase |
+| EIP-8038 | SSTORE gas repricing | COLD_STORAGE_WRITE = 5000 (was 22100); COLD_STORAGE_ACCESS unchanged at 2100 |
+| EIP-8246 | SELFDESTRUCT no-burn | ETH sent to address(0) via SELFDESTRUCT is dropped (not credited to address(0)) |
+| EIP-7981 | Reduce access list storage key cost | ACCESS_LIST_STORAGE_KEY_COST: 2400 → 1900 (address cost unchanged) |
+| EIP-8024 | SWAPN/DUPN/EXCHANGE opcodes | Three new EVM opcodes for stack manipulation; work in legacy bytecode |
+| EIP-7778 | Block gas accounting without refunds | block.gasUsed = pre-refund gas; refunds still issued to tx.origin (EIP-8037) but don't reduce block space |
+| EIP-7928 | Block-Level Access Lists | Every block header includes `blockAccessListHash`: Keccak256 of RLP-encoded BAL recording all state changes per-tx |
+| EIP-7976 | Increase calldata floor cost | floor_data_cost = 21000 + 64 × len(calldata); actual = max(standard, floor) |
+| EIP-8282 | Builder execution requests | Builder deposit/exit predeploys; requires genesis-generator >= 6.1.0 |

+  # EIP-7778: Block Gas Accounting without Refunds
+  #
+  # Background:
+  #   In Amsterdam (EIP-7778), block.gasUsed uses a 2-dimensional gas formula:
+  #     block.gasUsed = max(sum(tx_regular_gas), sum(tx_state_gas))
+  #   where tx_regular_gas = pre_refund_gas - tx_state_gas and tx_state_gas is
+  #   the BAL-sourced state access cost from EIP-8037.
+  #
+  #   Crucially, the block gas is tracked separately from sum(receipt.gasUsed):
+  #     block.gasUsed  = gp.Used()           = max(sum_regular, sum_state)
+  #     sum(receipts)  = gp.CumulativeUsed() = sum(max(pre_refund-refund, floor))
+  #   These two counters DIVERGE in Amsterdam (they were always equal pre-Amsterdam).
+  #
+  #   Refund per cleared SSTORE slot: COST_PER_STATE_BYTE(1530) × 64 = 97920 gas.
+  #   With 8 cleared slots: uncapped refund = 783360 gas (refund cap = pre_refund/5).
+  #
+  # Test approach:
+  #   1. Deploy StorageClearer, fill 8 slots, then clear all 8.
+  #   2. Get block.gasUsed for the block containing clear().
+  #   3. Sum all receipt.gasUsed for every tx in that block.
+  #   4. Assert: block.gasUsed != sum(receipt.gasUsed)  [2D gas accounting active]
+  #      The 8-slot clear() generates large SSTORE refunds via EIP-8037. In Amsterdam
+  #      these refunds cause block.gasUsed (max(regular,state)) to diverge from
+  #      sum(receipt.gasUsed). Pre-Amsterdam they were always equal.
+  #   5. Log the delta to show how block gas differs from receipt-based accounting.

+  # EIP-7843: Adds the SLOTNUM opcode (0x4b) that pushes the current beacon chain
+  # slot number onto the EVM stack. This allows smart contracts to read the beacon
+  # slot directly without an oracle.
+  #
+  # SLOTNUM (0x4b):
+  #   - Gas cost: 2 (same as TIMESTAMP/NUMBER)
+  #   - Stack: [] -> [slot_number]
+  #   - The slot number increases every 12 seconds (one beacon slot)
+  #   - At epoch 2 (slot 64), the value must be >= 64
+  #
+  # Test approach:
+  #   1. Verify SLOTNUM opcode is accepted (does not cause INVALID_OPCODE revert)
+  #   2. Deploy a SLOTNUM reader contract via the Arachnid CREATE2 factory (EIP-7997)
+  #      and call it to read back the slot number
+  #   3. Verify the returned value is a plausible beacon slot (>= 64 at epoch 2)
+  #   4. Verify the slot number advances between two calls (chain is live)
+  #

+  # EIP-7928: Block-Level Access Lists (BAL)
+  #
+  # Background:
+  #   In Amsterdam, every block header includes `blockAccessListHash` — the
+  #   Keccak256 of the RLP-encoded Block Access List. The BAL records all
+  #   state changes made during block execution: storage writes/reads, balance
+  #   changes, nonce changes, and code changes, indexed per-transaction.
+  #
+  #   Properties to verify:
+  #   1. `blockAccessListHash` is present in every Amsterdam block header.
+  #   2. The hash is a valid 32-byte non-zero value.
+  #   3. The hash differs between blocks with different transaction sets
+  #      (the BAL reflects actual state changes — not a static placeholder).
+  #   4. Two consecutive blocks built off the same parent each produce a
+  #      different BAL hash (BAL is block-specific, not chain-global).
+  #
+  #   The gas-optimization property (BAL warming across transactions) is
+  #   tested separately by the EELS execution spec test suite (eip7928 module).
+  #
+  # Test approach:
+  #   1. Wait for network stability (epoch 2).
+  #   2. Fetch 10 recent blocks.
+  #   3. Verify EVERY block has a non-empty `blockAccessListHash`.
+  #   4. Verify that multiple blocks have DIFFERENT `blockAccessListHash` values
+  #      (showing the BAL changes per block — not hardcoded).
+  #   5. Since EIP-4788 (activated at Cancun) writes the parentBeaconBlockRoot to a
+  #      system contract on every block, EVERY block has at least one state write even
+  #      when there are no user transactions. Therefore the empty-BAL sentinel
+  #      (keccak256(RLP([])) = 0x56e81f171bcc55a6ff8345e692c0f86e5b48e01b996cadc001622fb5e363b421)
+  #      must NEVER appear in a Cancun+ chain. Verify ALL blocks have non-empty BAL hash.

+  # EIP-7975: eth/70 — Partial Block Receipt Lists
+  #
+  #   Adds a new p2p wire message (ReceiptsMsg) that allows fetching partial
+  #   receipt sets per block. A peer that supports eth/70 will advertise this
+  #   capability during devp2p handshake. The partial receipt model reduces
+  #   network bandwidth when only a subset of receipts are needed.
+  #
+  # EIP-8159: eth/71 — Block Access List Exchange
+  #
+  #   Adds a new devp2p sub-protocol for exchanging Block Access List (BAL)
+  #   data between peers (EIP-7928). Nodes that support BAL optimization
+  #   (EIP-7928 warming) can share BALs so they can pre-warm storage slots
+  #   before executing the next block. The eth/71 capability is advertised
+  #   during devp2p handshake alongside existing eth/* sub-protocols.
+  #
+  # Test approach:
+  #   1. Wait for network stability (epoch 2).
+  #   2. Call `admin_peers` on each available EL client.
+  #   3. Verify at least one peer-pair has negotiated eth/71 (EIP-8159).
+  #   4. Verify at least one peer-pair has negotiated eth/70 (EIP-7975).
+  #   5. Smoke-test eth_getBlockReceipts on a transaction-bearing block to
+  #      verify the receipt retrieval infrastructure is healthy.
+  #
+  # Notes:
+  #   - admin_peers reports capabilities advertised by the REMOTE peer, not
+  #     necessarily what was negotiated — but if both sides support it, the
+  #     remote will advertise it.
+  #   - In a homogeneous test network (all clients are Amsterdam-capable),
+  #     eth/70 and eth/71 should appear on ALL connected peers.
+  #   - eth_getBlockReceipts is defined in eth/70 but is backward-compatible;
+  #     it is available via the EL JSON-RPC independently of the p2p protocol.

+  # EIP-8037: State creation gas refunds flow to tx.origin without the EIP-3529 cap.
+  #
+  # Background:
+  #   In Amsterdam (EIP-8037), when a tx creates new state (e.g. sets a storage slot
+  #   from 0→x) it is charged state gas = COST_PER_STATE_BYTE (1530) × StorageCreationSize (64)
+  #   = 97,920 per slot.
+  #
+  #   If the SAME transaction then clears that slot (x→0), restoring the original zero
+  #   value, the state gas is fully refunded (RefundState, no EIP-3529 1/5 cap).
+  #   This refund credits gasLeft directly, which is returned to the sender as ETH.
+  #
+  #   This is the "0→x→0 within same tx" SSTORE path (gas_table.go case 2.2.2.1):
+  #     RegularGas: SstoreResetGas − ColdSloadCost − WarmReadCost
+  #     StateGas refund: RefundState(64 × 1530 = 97920)  ← unlimited, no cap
+  #
+  #   Contrast with the EIP-3529 EVM refund counter (for clearing pre-existing storage,
+  #   case 2.1.2b), which IS capped at gasUsed/5 and only gives 4800/slot.
+  #
+  # Test approach (within-tx create+clear to trigger RefundState):
+  #   1. Deploy a StorageWriter contract with setAndClear(n) that:
+  #         - sets n slots from 0 → 1  (ChargeState: n × 97920 state gas spills to regular)
+  #         - immediately clears them back 1 → 0  (RefundState: n × 97920 added to StateGas)
+  #      After the first slot, RefundState builds a state reservoir that absorbs subsequent
+  #      slot charges without further regular-gas spillover.
+  #      Net effect: only 1 slot's worth (97920) of state gas spills to regular gas total.
+  #   2. Call setAndClear(8) and check receipt.gasUsed.
+  #   3. Assert gasUsed is in the "RefundState active" range:
+  #        With EIP-8037:    gasUsed ≈ 300000-500000  (only 1 spillover of 97920)
+  #        Without EIP-8037: gasUsed ≈ 900000-1100000 (all 8 spillovers = 783360 extra gas)
+  #      The two cases are easily distinguished — a ~3× difference in gasUsed.
+  #
+  # Why setAndClear in one tx?
+  #   If set() and clear() are separate txs, the second tx sees original=1 (not 0),
+  #   hitting case 2.1.2b (capped EVM refund, 4800/slot) NOT case 2.2.2.1 (RefundState).
+  #   Only when original==value==0 (restored to original zero within same tx) does
+  #   geth call RefundState and bypass the 1/5 cap.
+  #
+  # Note on balance accounting: RefundState increases gasLeft (not the EVM refund counter),
+  # so receipt.gasUsed ALREADY reflects the refund. The sender saves via lower gasUsed,
+  # not via a separate balance credit beyond the gasLeft return.

+  # EIP-8246: Remove SELFDESTRUCT burn.
+  #
+  # EIP-8246 removes the only remaining case where SELFDESTRUCT can burn ETH:
+  # when a contract created in the SAME TRANSACTION executes SELFDESTRUCT with
+  # itself as the beneficiary (newContract=true, beneficiary=self).
+  #
+  # Before EIP-8246 (Cancun/Prague, governed by EIP-6780):
+  #   SELFDESTRUCT(self) in creation tx → ETH burned (disappears from total supply)
+  # After EIP-8246 (Amsterdam):
+  #   SELFDESTRUCT(self) in creation tx → ETH stays in account, code/storage cleared,
+  #   nonce reset to 0. Balance preserved (no burn).
+  #
+  # IMPORTANT: EIP-8246 does NOT change SELFDESTRUCT behavior in non-creation txs.
+  # SELFDESTRUCT(address(0)) in a separate tx (after deployment) is governed by EIP-6780:
+  # ETH still moves to address(0). EIP-8246 only removes the burn for the same-tx case.
+  #
+  # Tests:
+  #   1. SELFDESTRUCT with non-zero beneficiary (non-creation tx, EIP-6780 behavior):
+  #      - Deploy contract with 0.5 ETH, call destroy(beneficiary) in separate tx
+  #      - beneficiary balance increases by exactly 0.5 ETH
+  #      - address(0) balance is UNCHANGED
+  #      - Confirms EIP-6780 non-creation-tx ETH routing works correctly.
+  #
+  #   2. Same-tx SELFDESTRUCT-to-self (EIP-8246 core behavior):
+  #      - Deploy contract with payable constructor that calls SELFDESTRUCT(address(this))
+  #      - After tx: contract address should have its original balance PRESERVED (not burned)
+  #      - After tx: code should be cleared (empty code at address)
+  #      - This is the key EIP-8246 change: balance preserved, no ETH leaves total supply.
