+# ADR 0001: Versioned Tonolith v2 beside v1
+
+## Status
+
+Accepted for implementation.
+
+## Context
+
+Tonolith v1 is a deployed testnet artifact with published ROM, static, code,
+StateInit, and state-hash commitments. Changing its storage, ABI, ISA, or hash
+preimages would make existing local and public evidence ambiguous.
+
+Tonolith v2 adds asynchronous ports, epochs, bounded queues, reliable delivery,
+and measured batching. Those features require new persistent fields and new
+message semantics.
+
+## Decision
+
+Implement v2 beside v1 using new versioned namespaces and schemas:
+
+- v1 contracts, tools, tests, artifacts, and evidence remain valid;
+- v2 uses `schemaVersion = 2`, `isaVersion = 2`, `abiVersion = 2`, and
+  `protocolVersion = 2` in its own implementation surface;
+- v2 commitment domains are distinct from v1 domains;
+- v1 programs may be used as v2 compatibility fixtures only after independent
+  v2 decoding proves identical architectural transitions;
+- deployed v1 instances are never migrated in place;
+- a v2 program or route change produces a new content-addressed StateInit;
+- v2 code has no privileged runtime mutation path.
+
+## Consequences
+
+The repository carries two implementations and two sets of fixtures during the
+transition. Shared utilities may be extracted only when bit-for-bit v1 tests
+remain passing and the extraction has compatibility vectors.
+
+The v2 verifier must identify the version from code/data commitments rather than
+from a human-readable name or an indexer label.
+
+## Release boundary
+
+V2 implementation and testnet work are permitted. Mainnet deployment requires
+the separate production gates, external reviews, current network-economics
+review, and explicit project-owner approval in the v2 engineering guide.

+# Tonolith v1 baseline for v2 work
+
+This record freezes the evidence reproduced before v2 implementation began.
+It is a local engineering baseline, not a new deployment claim.
+
+## Source and tools
+
+- branch at baseline: `main`;
+- baseline commit: `8663815`;
+- Acton: `1.0.0 (3a4f0dc 2026-05-11)`;
+- local Tolk executable: `1.3.0`;
+- Node.js: `v26.7.0`;
+- npm: `12.0.2`;
+- effective Git identity: `ef-code` /
+  `111162892+EF-Code@users.noreply.github.com`.
+
+## Reproduced local gates
+
+The following commands passed before v2 edits:
+
+```text
+acton fmt --check
+acton check
+acton build
+acton test --fuzz-seed 42
+acton test --coverage --coverage-format text --coverage-minimum-percent 89 --fuzz-seed 42
+acton test --snapshot benchmarks/gas-v1.json --fuzz-seed 42
+acton test --mutate --mutate-contract TonolithCpu --mutation-levels critical,major --mutation-workers 2 --fuzz-seed 42
+npm run typecheck
+npm test
+npm run build
+```
+
+Results:
+
+- 18/18 Acton contract tests pass;
+- 21 TypeScript tests pass;
+- 378/379 lines and 299/374 branches are covered by Acton;
+- blended Acton score is 89.9%;
+- mutation run: 223 killed, 9 survived, 6 compile-invalid, 238 total;
+- accepted v1 `Advance`: 1,588 minimum, 19,527 maximum, 15,266 average gas;
+- v1 batch cap: one instruction;
+- Fibonacci output: `1, 1, 2, 3, 5, 8, 13`;
+- Fibonacci final state hash:
+  `16925a27b1db66171cebb3d43c74702f06f4a362e302754f24026cca0a6bf2be`.
+
+The mutation survivors are retained as baseline evidence. They concern the
+Acton external-message shim and defensive out-of-range selectors that v1's
+typed address derivation cannot reach. V2 must test equivalent paths through
+its own validator-compatible boundary rather than silently inheriting the gap.
+
+## Untouched guide hashes at phase start
+
+These values were recorded before implementation edits:
+
+```text
+TONOLITH_IMPLEMENTATION_GUIDE.md
+1cd946c1765258962ffb198fabbc3f857160e680e23799cfb15070cb7e723d74
+
+TONOLITH_V2_ENGINEERING_GUIDE.md
+c87e421658a3fa48d115550bcfc5c0db8c1fb525a526e4c107e57907dc25b620
+```
+
+The files are intentionally excluded from v2 commits.
+
+## Public v1 reference
+
+The existing testnet Fibonacci contract and its transaction evidence remain the
+v1 public reference. V2 reports must label new local, local-validator, and
+testnet results separately from that run.

+# Tonolith v2 benchmark suite
+
+The v2 suite is executable, deterministic, and deliberately split into two
+evidence classes:
+
+- `local-emulator`: the independent TypeScript execution and message-routing
+  results checked by `tests/v2/benchmarks.test.ts`;
+- `acton-sandbox`, `local-validator`, and `testnet`: fields reserved for
+  measured contract, validator, and public-network evidence.
+
+The checked-in expected vectors are in [`expected.json`](expected.json). They
+include the source programs, output vectors, instruction counts, final state
+hashes, and multi-core acknowledgement counts. Gas and real network fees stay
+`null` until the corresponding environment measures them; they are not inferred
+from emulator runtime.
+
+Run the suite with:
+
+```text
+npm test -- --test-name-pattern='v2 benchmark suite|bounded checksum|two-core|two 4-bit'
+```
+
+The benchmark runner emits per-instruction frames compatible with the v2 trace
+schema. A frame is an architectural transition; it is not a claim that a TON
+transaction was included or finalized.

+# Tonolith v2 threat model
+
+This document describes the security boundary of the v2 architectural
+processor, its asynchronous core-to-core protocol, and the off-chain tooling.
+Tonolith is a deterministic processor state machine; it is not transistor-level
+or gate-level execution and it does not claim Intel 4004 compatibility.
+
+## Assets
+
+- The deployed code and immutable StateInit identity.
+- Program, ROM, RAM, route, peer, limits, and static commitments.
+- The accepted state-hash chain, logical epochs, counters, and queue contents.
+- Reliable output delivery, acknowledgements, deduplication, and bounded funds.
+- The independence and reproducibility of the emulator, verifier, artifacts, and
+  visualizer traces.
+- Keeper wallet funds and credentials held outside the repository.
+
+## Trust boundaries
+
+1. The immutable v2 contract is the consensus object. It does not trust a
+   keeper, emulator, assembler, RPC index, or visualizer.
+2. A keeper is an untrusted liveness agent. Any keeper can submit a bounded
+   request, but it cannot authorize state mutation or change static data.
+3. A peer address is authenticated by the immutable peer table and is not a
+   keeper allowlist.
+4. The verifier treats raw BOCs and transaction history as evidence. Indexed
+   decoded fields are advisory and cannot replace body or StateInit checks.
+5. The browser visualizer consumes verifier output and labels reconstructed
+   fields separately from chain facts.
+6. Wallet signing and RPC credentials are external operational dependencies.
+
+## Adversaries
+
+- A stale or racing keeper submitting an old state hash or counter.
+- A malicious sender impersonating a core, replaying an output, or mutating a
+  delivery field while retaining an output ID.
+- A provider returning incomplete, reordered, divergent, or fabricated history.
+- A poisoned artifact, source map, route table, or deployment manifest.
+- A malformed cell designed to trigger parser ambiguity, excessive depth, a
+  dictionary failure, an action-phase failure, or a queue overflow.
+- A compromised keeper host attempting to leak signing material or overspend.
+- A visualizer or API incorrectly presenting a dispatch as destination receipt
+  or finality.
+
+## Primary controls
+
+| Threat | Control | Evidence target |
+| --- | --- | --- |
+| stale/racing advance | expected counter + exact state hash; no privileged keeper | Acton stale and two-keeper tests |
+| forged delivery | immutable run/route/peer checks and authenticated sender | first-delivery, wrong-peer, and conflict tests |
+| replay | output ID binding, destination slot uniqueness, exact duplicate ACK | duplicate and conflicting-replay tests |
+| lost output | pending outbox remains until authenticated ACK; bounce does not erase it | retry/bounce tests |
+| queue exhaustion | fixed queue bounds and explicit backpressure | full-queue tests |
+| epoch confusion | route delay, epoch window, sequence and quota checks | stale-epoch tests |
+| artifact substitution | canonical files and recomputed commitments | artifact tamper tests |
+| StateInit substitution | code/data/StateInit/address recomputation | SDK and raw verifier tests |
+| provider disagreement | two-source fingerprint and continuity comparison | verifier disagreement test |
+| secret leakage | external wallet interface, read-only keeper mode, staged secret scan | release preflight |
+| false visual claims | explicit message phases and evidence class in trace schema | trace validation and UI integration |
+
+## Invariants
+
+- No external message changes state.
+- No keeper identity occurs in static commitments or authorization rules.
+- A stale request cannot mutate architectural or protocol state.
+- An output remains retryable until its matching authenticated acknowledgement.
+- An exact duplicate delivery is idempotent; a conflicting duplicate fails.
+- A route, peer, epoch, sequence, and output ID are jointly consistent.
+- A bounded request cannot create an unbounded queue, action list, cell graph, or
+  message body.
+- A verifier never returns `verified` when history, code, StateInit, BOCs, or
+  commitment comparisons are incomplete.
+- Local emulator and Acton evidence are not described as testnet or mainnet
+  evidence.
+
+## Residual risks and release gates
+
+The design still requires local-validator evidence for action rollback, bounce
+semantics, and final balance reconciliation; public testnet evidence for real
+inclusion, finality, fees, and independent keepers; and external review before
+any production or mainnet claim. A verifier/provider outage is an incomplete
+result, not permission to skip history. A keeper wallet compromise can still
+burn its own funds and must be contained by external spend limits.

+# Tonolith v2 local release record
+
+This record separates reproducible local evidence from public-network evidence.
+It is not a deployment approval. The v2 testnet gate remains closed while the
+coverage and mutation requirements below are open.
+
+## Toolchain observed
+
+- Acton `1.0.0`, git revision `3a4f0dc`;
+- Tolk `1.4.0` through the Acton installation;
+- Node.js `v26.7.0`;
+- npm `12.0.2`;
+- TypeScript cell dependencies from the checked-in lockfile;
+- effective Git identity `ef-code` /
+  `111162892+EF-Code@users.noreply.github.com`.
+
+## Commands and results
+
+| Gate | Command | Result |
+| --- | --- | --- |
+| Acton formatting | `acton fmt --check` | PASS |
+| Acton static checking | `acton check` | PASS |
+| Acton compilation | `acton build` | PASS |
+| Acton functional suite | `acton test --fuzz-seed 42` | PASS: 41 tests |
+| TypeScript typecheck | `npm run typecheck` | PASS |
+| TypeScript build | `npm run build` | PASS |
+| TypeScript suite | `npm test` | PASS: 71 tests |
+| Clean-directory reproducibility | `tests/v2/reproducibility.test.ts` | PASS |
+| Acton gas snapshot | `acton test --snapshot benchmarks/gas-v2.json --fuzz-seed 42` | PASS |
+| Acton coverage gate | `acton test --coverage --coverage-format text --coverage-minimum-percent 89 --fuzz-seed 42` | OPEN: 98.3% lines, 74.1% branches, 86.7% blended |
+| TypeScript coverage | `npm run test:coverage` | OPEN: 93.03% lines, 74.25% branches |
+| v2 critical/major mutation run | `acton test --mutate --mutate-contract TonolithCoreV2 --mutation-levels critical,major --mutation-workers 2 --fuzz-seed 42` | OPEN: 401 killed, 254 survived, 34 compile-invalid, 61.2% score |
+
+The open gates are recorded failures, not waived requirements. The Acton
+minimum-score command exits non-zero at the current 86.7% blended score. The
+mutation run also fails the required critical-mutant and major-mutant bars.
+Survivors need targeted tests or an explicit reviewed reachability disposition
+before this record can become a release approval.
+
+The repository does not currently contain a configured local TON validator,
+and no `lite-client`, `validator-engine-console`, `toncli`, or validator Docker
+image was available during this check. Acton emulation therefore does not prove
+validator action rollback, bounce delivery, external-message rejection at the
+validator boundary, or final balance reconciliation.
+
+## Gas and batching evidence
+
+The refreshed Acton snapshot in [`../../benchmarks/gas-v2.json`](../../benchmarks/gas-v2.json)
+measures these v2 message classes:
+
+- `V2Advance`: 1,844–47,997 gas, average 22,332 across 73 samples;
+- `V2DeliverInput`: 309–49,066 gas, average 16,819 across 20 samples;
+- `V2DispatchOutput`: 1,877–17,899 gas, average 8,728 across 5 samples;
+- `V2InputAccepted`: 309–23,418 gas, average 7,219 across 5 samples;
+- `V2TopUp`: 2,546–2,946 gas, average 2,798 across 3 samples.
+
+The complete candidate matrix is [`../../benchmarks/v2/batch-selection.json`](../../benchmarks/v2/batch-selection.json).
+The selected value is `MAX_STEPS_PER_ADVANCE = 1`. Its measured worst-case
+local contract gas is `47,997`, and its routed-output trace is `48,306` gas.
+Candidates 2, 4, 8, 16, and 32 remain below the local 400,000-gas project
+ceiling, while 64 reaches `677,438` gas and is rejected. No candidate can pass
+the guide's 40%-of-testnet-reference rule until a real testnet reference exists.
+Action count, storage-cell growth, message-size, and testnet fee gates remain
+open because Acton does not provide a stable release table for those fields.
+
+## Deterministic benchmark vectors
+
+The checked-in vectors in [`../../benchmarks/v2/expected.json`](../../benchmarks/v2/expected.json)
+are local-emulator evidence:
+
+- Fibonacci: `1, 1, 2, 3, 5, 8, 13`; 97 instructions and 97 one-step batches;
+  final state hash `8238d6bbcd507f4a3b9cba3b1ad48b2d88fd6ab11f7068b75340a3f0044a9f1f`;
+- CRC-4: output `5`, 12 instructions;
+- cellular automaton: output `0`, 50 instructions;
+- counter pipeline: outputs `1, 2`, two acknowledgements;
+- two-core 8-bit carry path: carry output `1`, two acknowledgements.
+
+Those hashes prove agreement between the checked-in emulator and its own
+canonical inputs. They are not TON transaction or finality evidence.
+
+## Testnet boundary
+
+Two global Acton testnet wallet entries are configured for the project, but no
+v2 deployment was attempted from this worktree because the local release gates
+are open. No v2 address, transaction, fee, storage balance, keeper race, or
+finality claim should be inferred from the wallet configuration.
+
+When the local gates pass, use the procedure in
+[`TESTNET_VALIDATION.md`](TESTNET_VALIDATION.md). Record every value from the
+chain and explorer output there; never replace a missing value with an emulator
+estimate.

+# Tonolith v2 testnet validation
+
+This is a testnet-only runbook. It is intentionally a blank evidence record
+until a release candidate has passed all local gates. The existing v1 run in
+[`../TESTNET.md`](../TESTNET.md) is separate evidence and must not be reused as
+v2 proof.
+
+## Release boundary
+
+Do not run the deployment script while any local release gate is open. The v2
+candidate must first pass formatting, checking, compilation, all Acton and
+TypeScript tests, reproducibility, coverage, mutation, and the gas/action/
+storage/message-size checks. Mainnet is out of scope.
+
+The current status is **not deployed**. The local Acton coverage and mutation
+gates are open, and this record contains no fabricated address or transaction.
+
+## Preflight
+
+```sh
+acton wallet list
+acton doctor
+acton fmt --check
+acton check
+acton build
+acton test --fuzz-seed 42
+npm run typecheck
+npm test
+```
+
+The deployment wallet is selected by the script as
+`tonolith-testnet`. A second independently funded keeper should be available
+as `tonolith-keeper-b`. Wallet files, mnemonics, signed messages, provider
+credentials, and API keys stay outside the repository and are never printed.
+
+## Single-core Fibonacci deployment
+
+After the local release record is green, run exactly the testnet selector:
+
+```sh
+acton script scripts/deploy-v2-fibonacci.tolk --net testnet --explorer tonviewer
+```
+
+Capture the script output and explorer data without committing secrets. The
+deployment record must contain:
+
+```text
+network: testnet
+address: <raw address>
+deployment transaction: <transaction link>
+deployment lt / masterchain reference: <values>
+code hash: <hash>
+initial data hash: <hash>
+StateInit hash: <hash>
+program id: e140cb991c86e81663dbe688da3e6a2b18d14b260b0aca0a0c7b1381707a7dda
+ROM root: 029ccf15774f680518705bb7c8be4b2ca92f34a4ceb9c963e55609225398c748
+RAM root: ed807133df392920f6ed73d30ab7e67ecaee528d940e1be1ea8e44cd25031b8e
+route root: 9e548d24c3c980ff9fe617f92286289613d6deae0b0da0cbe88aa8a51e6d9bcb
+limits hash: f8d3ee4ee34e55e437aa1decfa2742d81aa6d623beec67c9394d736376beb1fb
+static commitment: 2c5978dc7ca91a1899cd345f5e9232500f50670ac7612fddb30f64eb879677f9
+initial state hash: <hash>
+final state hash: <hash>
+```
+
+The immutable commitments above are the canonical Fibonacci artifact values;
+the address and StateInit hashes still depend on the compiled contract code
+and the complete network cell. Verify them from the actual StateInit BOC.
+
+## Transaction and keeper checks
+
+For the deployment and each accepted one-step `Advance`:
+
+1. confirm RPC submission, inclusion, and masterchain-referenced finality as
+   separate observations;
+2. record gas used, computation/action/forward/storage fees, balance, and
+   reserve behavior;
+3. verify `advanceCount`, `instructionCount`, PC, output event, previous-state
+   hash, next-state hash, and the next expected message;
+4. submit one tick from `tonolith-keeper-b` rather than the deployer;
+5. deliberately submit a stale count/hash from the other keeper and verify
+   rejection with no architectural state change;
+6. retry with the fresh count/hash and verify exactly one accepted mutation;
+7. replay the accepted history with the independent verifier using two
+   independent chain data sources;
+8. export a trace accepted by the visualizer and label it `testnet`, never
+   `local-emulator`.
+
+The expected output sequence is `1, 1, 2, 3, 5, 8, 13`. A testnet claim is
+incomplete unless the output events, final state hash, actual fees, and finality
+are all recorded.
+
+## Multi-core boundary
+
+The TypeScript emulator proves authenticated routing, duplicate delivery,
+acknowledgement, retry, backpressure, counter-pipeline, and two-core carry
+vectors locally. A production multi-core testnet deployment additionally needs
+a non-circular address/StateInit manifest for every peer. The current immutable
+peer table binds exact peer addresses into each core's static data, so two cores
+that derive each other's addresses cannot be deployed by independently guessing
+those addresses. Until a reviewed address-manifest scheme or factory is added,
+multi-core deployment remains an unresolved engineering gate and must not be
+described as testnet-proven.
+
+## Evidence ledger

+## Tonolith v2
+
+Tonolith v2 is the versioned multi-core architecture under active engineering.
+It adds an immutable `TonolithCoreV2`, versioned ABI and commitments, bounded
+inboxes/outboxes, logical epochs, authenticated input delivery,
+acknowledgements, retry-aware output dispatch, a permissionless bounded
+`AdvanceV2`, a browser-safe SDK, an independent verifier, a testnet-only keeper,
+and trace files that the [Tonolith Visualizer](https://github.com/EF-Code/tonolith-visualizer)
+can consume.
+
+The current local evidence includes **42/42** Acton tests, **73/73** TypeScript
+tests, deterministic Fibonacci/CRC-4/cellular-automaton vectors, a two-core
+counter pipeline, and a two-core 8-bit carry path. The v2 Fibonacci emulator
+produces `1, 1, 2, 3, 5, 8, 13` in **97 one-step batches** with final state hash
+`8238d6bbcd507f4a3b9cba3b1ad48b2d88fd6ab11f7068b75340a3f0044a9f1f`.
+
+The measured local `V2Advance` worst case is **47,997 gas**. The selected
+`MAX_STEPS_PER_ADVANCE` remains **1** until a real testnet gas reference and
+the remaining action, storage, message-size, coverage, and mutation gates are
+complete. The full [v2 local release record](docs/v2/LOCAL_RELEASE.md),
+[batch-selection matrix](benchmarks/v2/batch-selection.json), and
+[testnet validation ledger](docs/v2/TESTNET_VALIDATION.md) keep those evidence
+levels separate. No v2 testnet deployment is claimed by the current branch.
