Subject: [PATCH 01/16] quantum phase 4: lock parity with tests, fixtures,
 docs, and CI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Pin composite cosigned RLP envelope against drift with golden-hex assertion in `detached_p256_cosigner_is_attached_to_composite_signature`: raw_len=2563, primary_only_len=2495, raw_hash=0x8c6ef4e5…. Any change to field ordering, scheme-byte placement, or cosigner layout flips the constants and fails the regression.
- Rewrite `README.md` Quantum-first (mirroring tempo-foundry layout): intro, Installation, and Changeset listing `cast send --quantum`, `cast quantum {bootstrap,add-key,remove-key,update-key-auth}`, `cast call` lifecycle rejection, `forge create --quantum`, and `forge script` paths. Upstream Foundry README preserved below.
- Rename `ci-tempo.yml` → `ci-quantum.yml` and rebuild job structure: `cargo fmt --all --check`, `cargo clippy --workspace --all-targets -- -D warnings`, Quantum-scoped package tests (`-p foundry-common -p foundry-primitives -p foundry-cli`), and Quantum fixture regression (`generated_fixture_matches_checked_in_phase0_example`, `detached_p256_cosigner_is_attached_to_composite_signature`). Inline comment documents why the broader workspace test is intentionally not gated (pre-existing upstream tests hit external networks). Retains QUANTUM_FOUNDRY_BASE_COMMIT and QUANTUM_HARNESS_COMMIT env metadata.
- Register `ci-quantum.yml` and `README.md` in `docs/dev/quantum-adapter-touchpoints.md`.
- Fix pre-existing `include_str!` path (`../../../` → `../../../../`) that pointed at `crates/testdata/` instead of repo-root `testdata/`; add missing `use alloy_network::ReceiptResponse as _;`; cluster of clippy fixes surfaced by the first-time `-D warnings` gate (const fn, use_self, redundant_clone, bool::then, format! inline args, unwrap-after-is_none pattern, too_many_arguments). No behavior changes.

+# Quantum Foundry
+
+Quantum is a post-quantum-ready EVM execution environment with a dedicated native transaction type (`0x7A`), explicit account lanes, and an ML-DSA-44 primary signer with optional detached classical cosigners.
+
+`Quantum Foundry` is a custom fork of [Foundry](https://github.com/foundry-rs/foundry) that integrates Quantum's native envelope, KeyVault lifecycle UX, and detached-cosigner contract directly into the familiar Foundry developer workflow.
+
+This fork is a drop-in replacement for upstream Foundry while Quantum-specific features are being stabilized; it tracks Foundry commit `f1abb2ca347187bb6dea8c3881ca44ce50aab1e7` and the Quantum harness commit `8f3612c60f9fa66ea3a09eab99a2e0802f373673`. See [`docs/dev/quantum-phase0-implementation-note.md`](./docs/dev/quantum-phase0-implementation-note.md) for the frozen RPC, signer, and ABI contract.
+
+## Installation
+
+Build from source in this repository:
+
+```sh
+cargo build --release -p forge -p cast -p anvil -p chisel
+```
+
+The `target/release` binaries are drop-in replacements for upstream `forge`, `cast`, `anvil`, and `chisel`.
+
+## Changeset
+
+Key Quantum extensions on top of upstream Foundry:
+
+- In `cast send`:
+  - `--quantum`: opt into the explicit Quantum adapter path (selection is explicit in v1, not inferred from chain ID).
+  - `--quantum.sender <ADDRESS>`: explicit Quantum account-lane address. Quantum writes never auto-derive the sender from the signing key.
+  - `--quantum.key-id <KEY_ID>`: account-lane key ID; defaults to `0` for ordinary v1 flows.
+  - `--quantum.primary-seed-file <PATH>`: canonical v1 ML-DSA-44 signer seed (single 32-byte hex seed, with or without `0x`).
+  - `--quantum.cosigner-artifact <PATH>`: optional detached v1 cosigner artifact JSON; schemes `p256` and `ecdsa` are supported and the artifact's `signing_hash` must match the fork-computed Quantum signing hash byte-for-byte.
+  - KeyVault lifecycle selectors (`bootstrapKey`, `addKey`, `removeKey`, `updateKeyAuth`) are rejected by the `cast send` pre-build guard and must be submitted through `cast quantum` instead.
+
+- In `cast quantum` (new subcommand group for KeyVault lifecycle UX):
+  - `cast quantum bootstrap`: primary-only `bootstrapKey()` through the shared `0x7A` signing pipeline.
+  - `cast quantum add-key`: `addKey(...)` with `--auth-key-id` (signer lane) distinct from `--target-key-id` (entry being added) so the two lanes cannot be confused.
+  - `cast quantum remove-key`: `removeKey(uint32)`.
+  - `cast quantum update-key-auth`: `updateKeyAuth(...)` with the same auth-lane / target-lane separation.
+  - All lifecycle writes auto-apply the fixed `QUANTUM_LIFECYCLE_GAS_FLOOR` (2,100,000) because validator-published transient state cannot be reproduced by `eth_estimateGas`.
+
+- In `cast call`:
+  - Fails closed on KeyVault lifecycle selectors with the frozen `QUANTUM_CALL_LIFECYCLE_REJECTION_MESSAGE`, preserving ordinary read paths on standard RPC simulation.
+
+- In `forge create`:
+  - `--quantum` and the `--quantum.*` flags route CREATE through the shared Quantum adapter with the same explicit sender / key-id / seed / cosigner contract as `cast send`.
+
+- In `forge script`:
+  - Scripted broadcast routes through the shared Quantum adapter for supported write shapes and fails closed on unsupported Quantum script shapes with a stable rejection message.
+
+- Additionally:
+  - A shared `QuantumWriteRequestV1` write contract with fail-closed v1 validation: `nonce_key` must be `0`, multi-call bundles are rejected, and lifecycle-selector misuse is caught before signing.
+  - Detached cosigner artifact v1 (`version = 1`, `scheme`, `signing_hash`, `public_key`, `signature`) with composite-signature RLP layout using scheme bytes `0x01` (ML-DSA), `0x02` (P256), `0x03` (ECDSA).
+  - KeyVault lifecycle calldata builders derived from a shared `sol!` interface whose selectors are asserted byte-for-byte against the Phase 0 frozen constants.
+  - A pinned golden fixture (`testdata/fixtures/quantum/phase0/raw-send-primary.json`) that locks the raw `0x7A` envelope bytes end-to-end.
+
+See [`docs/dev/quantum-adapter-touchpoints.md`](./docs/dev/quantum-adapter-touchpoints.md) for the full manifest of Quantum-modified files.

Subject: [PATCH 07/16] address PR review findings: lifecycle fence, auth-list,
 bootstrap cosigner, value, and call guard
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Addresses five findings from thoughts/shared/reviews/2026-04-20-foundry-fork-review-findings.md.

Finding 1 (High) — `cast send --quantum` lifecycle fence bypass via name/ENS: the pre-check inspected the unresolved NameOrAddress, so a name that resolves to the KeyVault slipped past the "use cast quantum" guard and skipped the bootstrap gas-floor. Destination is now resolved against the provider up front, and the fence + bootstrap gas-floor block observe the resolved Address.

Finding 2 (High) — `--auth` silently dropped on Quantum 0x7A: the Quantum envelope does not carry EIP-7702 authorization lists (`QuantumTxEnvelope::authorization_list()` returns None). `cast send --quantum` now rejects non-empty `--auth` with an explicit error instead of building a signed envelope that omits the auth list.

Finding 3 (Medium) — bootstrapKey cosigner policy inconsistency: `cast quantum bootstrap` rejects cosigner artifacts but `cast send --quantum` to bootstrapKey() silently attached one, producing an envelope shape the dedicated lifecycle CLI refuses. `cast send --quantum` now rejects `--quantum.cosigner-artifact` when the call is bootstrapKey(), aligning both sanctioned entry points.

Finding 4 (Medium) — `cast quantum` lifecycle --value claimed ignored but preserved: help text promised value was ignored, but builder.rs copied value straight into QuantumSingleCall. `submit_lifecycle` now rejects non-zero `--value` explicitly rather than silently forwarding ETH to bootstrapKey()/addKey()/etc.

Finding 5 (Medium) — `cast call` guard rejected by selector alone: any unrelated contract whose selector collided with a KeyVault lifecycle selector was blocked on the read path. The guard now requires `to == QUANTUM_KEYVAULT_ADDRESS` in addition to the selector match.

Drops `quantum_send_requests_bootstrap` and `quantum_destination_is_keyvault` helpers (no longer needed after the resolution-first rewrite). Adds regression `cast_call_allows_colliding_selector_on_non_keyvault_destination` pinning finding 5.

Subject: [PATCH 08/16] address review findings from 2026-04-20 foundry fork
 review

- envelope round-trip corruption: store semantic pubkey bytes in QuantumTxEnvelope
  so sign-verify-resubmit does not double-wrap init_primary_pubkey / init_cosigner_pubkey
  through the list-string framing
- cast send bare-name bypass: reject bootstrapKey / unsupported lifecycle names
  even without '(...)' or '0x' selector prefix
- cast call bare-name bypass: apply the same bare-name rejection on the read path
- cast quantum: verify caller-supplied init_primary_pubkey matches derived pubkey
- cast quantum: enforce --from vs --sender consistency before broadcast
- forge create --quantum: explicitly reject --auth since the 0x7a envelope does
  not carry 7702 authorization lists
- CI: include cast in the quantum package test gate

Subject: [PATCH 09/16] address 2026-04-20 foundry fork review findings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- cast send --quantum and shared signer now reject a caller-supplied
  init_primary_pubkey that does not match the key derived from the
  signing seed, matching the dedicated lifecycle command.
- forge create --quantum rejects the legacy-fee path up front so
  --legacy or legacy-marked chains fail with a clear invariant
  instead of failing late in EIP-1559 signing.
- Quantum envelope decoder now requires the reserved fee-payer
  placeholder fields to be empty lists; any non-empty value is
  rejected so decode→re-encode cannot silently change the tx hash.

Findings from thoughts/shared/reviews/2026-04-20-foundry-fork-review-findings.md:

- cast call: resolve name/ENS destination before the KeyVault lifecycle
  fence so a name that resolves to QUANTUM_KEYVAULT_ADDRESS cannot
  bypass the fail-closed check and reach eth_call.
- cast quantum: reject conflicting --primary-seed-file and
  --cosigner-artifact vs the shared --quantum.* forms instead of
  silently preferring one side.
- cast quantum: reject --browser, Tempo, blob/EIP-4844, and --legacy
  flags up front on the lifecycle path; mirrors the guards in
  cast send --quantum and forge create --quantum.
- cast send --quantum: reject --legacy up front; matches the early
  clear rejection already implemented on forge create --quantum.

Subject: [PATCH 11/16] reject blob flags on all Quantum write paths

cast send --quantum and forge create --quantum applied --blob /
--eip4844 / --blob-gas-price through the shared TransactionOpts, but
the Quantum transaction builder leaves blob setters on default no-op
implementations, so those flags were silently dropped rather than
producing a deterministic rejection. Mirrors the cast quantum
lifecycle guard.

Subject: [PATCH 12/16] document Quantum recover_signer semantics and reject
 empty sender_sig

ML-DSA signatures are not recoverable; authoritative verification requires
the sender's registered pubkey from KeyVault state, which only the Quantum
node can resolve. `SignerRecoverable` for `QuantumTxEnvelope` therefore
returns the declared sender, matching the precedent set by non-ECDSA
envelopes like `OpTxEnvelope::Deposit`.

Add a comment block that makes the rationale explicit, plus a cheap
structural guard that rejects envelopes with an empty `sender_sig` so
trivially malformed inputs cannot masquerade as recovered signers on
consumers such as `cast decode_raw_transaction` and Anvil mempool
admission. Cover the guard with a focused unit test.

Subject: [PATCH 13/16] docs(foundryup): publish quantum install path and
 devnet endpoints

Add a quantum-foundry install flow that coexists with upstream Foundry:
foundryup and install scripts default to ~/.foundry-quantum/ (not
~/.foundry/), foundryup -U self-updates from multivmlabs/quantum-foundry,
and --network quantum points at the fork's GitHub Releases. Extend the
binary-download fast-path to accept multivmlabs/quantum-foundry and
tempoxyz/tempo-foundry as known release repos.

Document the install path in the root README and foundryup README, add a
Devnet section with the public RPC, chain ID, and explorer, and demote
"build from source" to a collapsible for contributors and unsupported
platforms.

Subject: [PATCH 14/16] chore(deps): bump thin-vec to 0.2.16 and drop stale
 bincode advisory ignore

Fixes `deny / cargo deny check` on PR #5:

- GHSA-xphw-cqx3-667j: thin-vec 0.2.15 has a double-drop on panic
  during `IntoIter`/`clear`; bump to 0.2.16 via `cargo update`.
- RUSTSEC-2025-0141: bincode is no longer in the dependency tree,
  so the ignore entry now fails `advisory-not-detected`. Removed.
