/**
* @title Final Certificate
* @notice Reads a Final Certificate on chain and self-checks it, so a certificate's keys can never be
* anything other than the keys it declares.
* @dev Deployed only as part of this project's own reth-based state plane, and only on the reth-based chains
* that carry the precompiles it calls: SHA3-256 at `0x0202`, ML-DSA-87 at `0x0204` and
* SLH-DSA-SHAKE-256s at `0x0205`, each address being that primitive's FIPS number. The contracts it is
* linked into probe those precompiles at construction and refuse to exist where they are absent, so
* this library never runs somewhere its verdicts would be meaningless. It takes part in no CREATE2
* derivation, and nothing outside this directory imports it.
*
* The SHA3 precompile is not a convenience: the certificate format hashes with FIPS-202 SHA3 and the
* EVM's `keccak256` is a DIFFERENT function, so a digest computed with the wrong one matches no
* certificate any issuer ever wrote.
*
* ## Why the chain parses this at all
*
* The alternative is taking the TBS bytes and the public keys as separate arguments and deriving
* `certHash` from the bytes. That looks like verification and is not: nothing compares the keys to the
* certificate, so a registrar could bind any certificate to any keypair, the registry would hold a key
* the certificate does not contain, and every signature that key produced would verify against a
* certificate that never authorised it.
*
* So the keys are read OUT of the certificate. There is one input, and no pair of arguments that can
* disagree.
*
* Gas is deliberately not a design constraint on the chain this runs on and must not be optimised for.
* Parsing and re-hashing on chain costs more than trusting a parse done elsewhere and buys a verdict
* that is re-derivable from public state, which is the trade this whole plane is built on.
*
* ## The key-identifier check
*
* A certificate declares `SubjectKeyId` as the SHA3-256 digest of its `PublicKeyBlock`. Having parsed
* that block, {parse} recomputes the digest and compares. The field sits inside the TBS, so it is
* covered by the issuer's signatures — which makes the check a statement about what the issuer
* attested, not merely about internal consistency of bytes the caller supplied.
*
* ## Deploy-linked, not inlined
*
* {parseLive}, {parseRecovery}, {parseCa} and {verifyIssuerSignatures} are `external`, so the identity
* registry calls them across a link boundary rather than carrying them in its own bytecode, which it
* has no room for. The link target is fixed at deployment: a linked library is code, not a pointer
* anyone can move afterwards.
*
* ## What this library deliberately does not do
*
* It does not verify an issuer's signatures over the TBS as part of parsing, and it does not walk a
* certificate chain to the root. On the registration path there is nothing to walk — a chain-attested
* certificate is admitted by this chain against pinned issuer constants and the holder's own proof of
* possession, so an issuer signature is not what makes it valid. {verifyIssuerSignatures} is here for
* callers verifying an off-chain issuance, and it verifies exactly what it is handed.
*
* It also does not check an encapsulation key's length or structure. Those are checked where they are
* REGISTERED, by the precompiles that own the answer, because two checks of one thing in two shapes is
* how one of them ends up weaker and nobody notices which.

* @title Final Chain Initializable
* @notice The once-only initializer of a Final Chain state-plane contract that stands behind `FinalChainProxy`
* (ruled 2026-09-12: every plane contract does).
*
* @dev The proxy never re-runs an implementation's constructor, so a constructor that writes STORAGE — the
* trees' zero-hash ladder and live roots, a bootstrap admin, the supply's 100M — would leave the proxy's
* storage empty: the writes land in the implementation, which nothing reads through. Such a contract
* moves those writes into one internal `_setUp(...)` guarded by {initializer} and calls it from BOTH
* places: its constructor (a direct deploy — every Foundry fixture, every test — behaves exactly as
* before, and the bare implementation marks its OWN storage initialized, so nobody can initialize it
* later) and an external `initialize(...)`, which `FinalChainProxy`'s constructor runs by `delegatecall`
* in the proxy's storage. Constructor immutables (`registry`, `trees`, …) need none of this: they live in
* the implementation's code and read as constants through the proxy.
*
* The flag lives in a namespaced slot, not in Solidity storage: inheriting this contract shifts no
* layout, and an implementation upgraded in place can never collide with it. An upgrade that appends
* storage seeds it through a new guarded function of its own — `initialize` runs once per proxy, ever.
*
* A proxy deployed WITHOUT its init data is a live hole: `initialize` is external and the first caller
* would be the admin. The deploy tool refuses to place a proxy whose implementation declares
* `initialize` without running it, and reads {initialized} back before it continues.

/**
* @title Final Chain Precompiles
* @notice The three primitives Final Chain adds to the EVM, and the only
* supported way to reach them.
*
* @dev **These exist ONLY on Final Chain (chain id 48359).** They are provided
* by this chain's own node binary, and
* nothing at these addresses on Ethereum, Optimism or any other chain will
* answer. A contract that calls them must be one that only ever runs here;
* `assertAvailable` below is the cheap way to fail loudly rather than treat an
* empty return as a verified signature.
*
* The addresses are the FIPS numbers, which is the whole allocation rule —
* there is no local registry to consult and no way for two implementations to
* disagree about where a primitive lives:
*
* | address | primitive | FIPS |
* |---|---|---|
* | `0x…0202` | SHA3-256 | 202 |
* | `0x…0203` | ML-KEM-1024 key validation | 203 |
* | `0x…0204` | ML-DSA-87 verify | 204 |
* | `0x…0205` | SLH-DSA-SHAKE-256s verify | 205 |
* | `0x…0207` | HQC-5 key validation | 207 |
*
* The two KEM addresses VALIDATE keys and do nothing else, for one reason:
* encapsulation is a SENDER operation and decapsulation needs the secret key,
* so neither belongs on a chain at all. Checking that a registered public key
* is well-formed is hardening rather than a dependency, and nothing in this
* system waits on it.
*
* HQC's number is 207. It had none when the KEM pair was chosen, which was the
* one thing separating it from ML-KEM here — a primitive with no standard
* number has no address under this rule, and inventing one would have been a
* local convention masquerading as the global one.
*
* **No AEAD precompile, at any number.** The chain must never be able to
* decrypt an intent, and checking a revealed body against its commitment is a
* hash compare that `0x0202` already serves.
*
* ## Why this library refuses to take a public key from its caller
*
* It does take one — the primitives are pure functions and cannot do otherwise.
* The rule lives one level up, in `FinalPqQuorum`: a key passed as an argument
* proves nothing, because anyone holding a keypair can produce a valid
* signature under it. Only a key read from `FinalIdentityRegistry` is evidence
* about WHO signed. Every call site here must be able to answer "where did this
* key come from" with "storage", never "calldata".
*
* ## `success` is not the answer
*
* A `staticcall` to a verifier returns two things and both matter. `success`
* false means the call was malformed — usually a length bug in the caller — and
* `success` true with a zero word means the signature did not verify. The
* helpers below collapse both to `false` for the caller's convenience, which is
* safe in that direction and only in that direction: treating a failed call as
* a valid signature would be the whole security of the system.

*
* A field or constant carrying a duration or an instant on this chain ends in `Ms`. This is not decoration. A
* delay field named for seconds while holding milliseconds elapses a thousand times too fast: a one-day
* recovery delay would mature in about eighty-six seconds, and a two-year dormancy threshold in under a day.
* Those delays are the whole of what stands between a stolen credential and an account, so a name that states
* the wrong unit is not a cosmetic defect — it is the defect, wearing a disguise. `Seconds`-suffixed names do
* not appear in this directory and must not be introduced.
*
* A test harness is not a check on this. Standard EVM tooling stamps `block.timestamp` in seconds, so a suite
* can agree with the contracts under test and both be wrong about the chain they deploy to. The unit has to be
* carried by the names.
*
* Solidity's `hours` and `days` suffixes remain the clearest way to write a duration, so durations are written
* as `24 hours * MS_PER_SECOND` rather than as a bare literal: the intent stays readable and the unit stays
* explicit at the point of use.

* either id is refused as `WrongAlgorithmForSlot`.
*
* `FinalCertificate` — the library the identity registry links — parses a fixed
* slot set (the wallet's two stages) and refuses anything else, so this
* contract carries its own parser for the endpoint profile rather than
* re-linking the adopted registry. Admission follows the identity registry's
* v5 path exactly: the registrar quorum is the authority, the holder's proof of
* possession (its live ML-DSA-87 network-authentication key over the admission
* digest, plus SLH-DSA when the certificate carries that key) is the evidence,
* and there is no CA signature on the certificate at all.
*
* An endpoint certificate is ≈ 12 KB (HQC-5's 7 237-byte public dominates; v1
* certificates were ≈ 1.4 MB because of McEliece), so `MAX_CERT_BYTES` is 32 KiB
* and a registration is an ordinary transaction. The parser still reads calldata
* in place and hashes the TBS ONCE into memory, taking the subject-key-id digest
* from the same buffer (`_sha3Slice`): the single-copy discipline costs nothing
* and keeps the parser the shape that carried 1.4 MB.
*
* The leaf (tree 8, branch 4, key `trees.endpointKeyFor(endpointId)`):
* keccak256(abi.encode(DOMAIN_ENDPOINT_LEAF, certificateHash, status, notAfter, region))
* with `endpointId` = the certificate's subject key id and `status` 1 active /
* 2 revoked — so revocation is a leaf change a client proves against the root
* an execution chain anchors, like an account leaf. A client pins the three
* endpoint fingerprints in its build, verifies the first session against them,
* then reads this leaf through the tunnel it just opened.

/**
* @title Final Identity Registry
* @notice Who every party in the system is, on chain: one record per party, carrying its certificate and its
* actual public keys.
* @dev Every service, every co-signer, every certificate authority and every operator has one record here.
* The record holds the party's public keys in full rather than commitments to them, and this contract is
* the certificate authority as well as the roster.
*
* ## Where this runs
*
* Only on this project's own reth-based chains. Verification happens inside precompiles that exist
* nowhere else: SHA3-256 at `0x0202`, ML-DSA-87 at `0x0204` and SLH-DSA-SHAKE-256s at `0x0205`, each
* address being that primitive's FIPS number. The constructor probes them and refuses to deploy where
* they are absent, so a registry of keys the chain cannot check never comes into existence. This
* contract takes part in no CREATE2 derivation — its address is per chain, and nothing derives an
* address from it — and nothing outside this directory imports it.
*
* Gas is deliberately NOT a design constraint on that chain and must not be optimised for. Where a
* choice below trades gas for a verdict that is re-derivable from public state, the verdict wins: a
* signature checked in a precompile is a fact anyone can recompute, where the same check run in a
* library by whichever process happened to hold the keys is only a claim.
*
* ## Keys are read from STORAGE, never from calldata
*
* A commitment would be a quarter of the storage and would be enough to CHECK a key someone hands you.
* It is not enough to VERIFY A SIGNATURE, because verification needs the key itself — and a key that
* arrives in calldata proves nothing, since anyone holding a keypair can produce a valid signature under
* it. A quorum built on caller-supplied keys is a quorum of one: whoever built the calldata.
*
* So the keys live here in full. `FinalPqQuorum` resolves a member through this registry and reads that
* member's key from this registry's storage, and "which key is co-signer three" has exactly one answer,
* in exactly one place. That is the load-bearing rule of every quorum on the chain, not an optimisation.
*
* ## The certificate is the record, not a pointer to one
*
* `certHash` is `SHA3-256(TBSCertificate)`: the certificate's own identity, and the handle revocation is
* keyed on. {registerWallet} and {registerIssuer} take the certificate's TBS bytes and read everything
* out of them — the digest, the serial, the key identifiers, the depth pair, the validity window and
* every public key. Neither takes a key argument, so no two arguments can disagree and no registrar can
* bind a certificate to a keypair that certificate does not contain.
*
* ## The root is the first record here, not a self-signed file
*
* This chain is the only root certificate authority, and the root is pinned as an entry in this registry
* rather than distributed as a self-signed certificate somebody has to install. Chain validation
* terminates here BY IDENTITY. Everything registered after the root is verified on chain, inside the
* precompiles, against what this registry already holds: the holder's own two signatures over the
* admission digest, the pinned chain-issuer constants, and — for a nested issuer — lineage to a
* registered parent whose depth admits it. There is no path by which a key enters this registry
* unattested; a registrar cannot register anything else.
*
* ## Roles are a bitmask
*
* One party is legitimately several things: a co-signer that also publishes, an operator that is also a
* guardian. A single enum would force either duplicate records for one key, which is two sources of
* truth about one party, or a role hierarchy nobody agrees on. A mask has neither problem, and a quorum
* asks whether an account CARRIES a capability rather than whether it IS a type.
*
* ## Membership is hybrid-gated
*
* Who is in this registry, and with which roles, is the root of every quorum on the chain, so it is the
* one thing no single key may decide. Once bootstrap is sealed, every membership mutation — register,
* roles, revoke, a hash-based signing key, the registrar threshold itself — and every state-plane
* configuration change routed through {requireRegistrarQuorum} takes a `ROLE_REGISTRAR` quorum whose
* approvals carry BOTH families: the ML-DSA-87 vote and the SLH-DSA seal. A lattice break cannot then
* rewrite the roster, and neither can a hash-function break; only both at once.
*
* The bootstrap window is the only exception. While it is open the bootstrap admin writes alone, because
* every roster has to be installed by someone before it can install itself. {sealBootstrap} closes it
* irreversibly, and refuses to close it onto a registrar quorum that cannot be met.
*
* ## The sender is not the account
*
* Transactions on this chain are signed by ML-DSA-87, and the node derives `msg.sender` from the key as
* `keccak256(0x04 ‖ publicKey)[12:]`. That address pays gas and holds no authority. {accountOfSender}
* binds it to the identity whose live transaction key it derives from, so a `msg.sender` gate anywhere
* on this chain asks {senderHasRole} and resolves to the identity — and a key rotation moves the binding
* instead of the roster.
*
* ## What this contract deliberately does not do
*
* It never un-revokes: a revoked certificate is finished, and reversing that would reopen every past
* verification. It never enumerates a mapping inside a mutation — the registrars supply the chain list a
* revocation touches, and a fingerprint an incomplete list missed stays permanently recordable through
* the revocation log's own permissionless door. It holds no funds, exposes no payable entrypoint, and
* reserves nothing against a sweep. And it grants no capability by parsing one: a certificate says which
* keys a party holds, `roles` says what the party may do, and the two arrive as different arguments on
* purpose.

* @notice Register or rotate an ISSUER: a third party, or one of this system's own intermediates, that
* signs certificates off chain with the keys registered here.
* @dev Admission is chain-native like any identity — the registrar quorum authorises, and the holder's
* own proof of possession establishes that the party controls the keys it is claiming. The
* delegation rules survive as LINEAGE: a nested issuer's depth, delegation bound and
* `AuthorityKeyId` must chain to its registered parent. No parent signs anything; this chain's
* admission IS the issuance.
*
* A registered issuer always expires, and its window is bounded by {MAX_ISSUER_VALIDITY_MS}.
*
* An institution must carry its real ISO 3166 country in its subject name, matching the
* `jurisdiction` field of its institution extension. That is enforced at the door because a
* verifier's legal recourse starts with knowing where an issuer answers for itself.
*
* `ROLE_CERTIFICATE_AUTHORITY` is added to whatever `roles` asks for, rather than being required in
* it: the capability is what this entry point means, so it cannot be forgotten in an argument.
* @param account The issuer's account on this chain.
* @param tbs The issuer certificate's TBS bytes: two cert-signing keys, ML-DSA-87 and
* SLH-DSA-SHAKE-256s, and no recovery stage — renewing an issuer is re-issuing, a governance act
* rather than a key rotation.
* @param parent The registered parent issuer for a nested intermediate; zero for an issuer hanging
* directly under the chain.
* @param proof The issuer's own two cert-signing keys over the admission digest. The recovery-handle
* slot in that digest is zero, because there is no recovery stage to bind.
* @param roles Capability bitmask, over and above the certificate-authority bit this call adds.
* @param version Monotonic. A rotation that does not advance it is refused.
* @param anchorBlock The block the registrars read the roster at. Ignored while bootstrap is open.
* @param approvals The sealed registrar quorum. Empty while bootstrap is open. The digest binds the
* account, the certificate bytes, the parent, the roles and the version.

/**
* @title Final Plane Sweep
* @notice The authority and destination halves of the shared asset-rescue surface, answered once for every
* contract of the protocol's own state plane.
* @dev `FinalSweep` gives every contract that can end up holding a stray asset one rescue surface and leaves two
* questions for the inheritor: who may call it, and where the value may go. Every contract on this state
* plane answers both the same way — the registry's bootstrap admin alone while that window is open, and the
* sealed registrar authority afterwards — and stating that once per contract would be one chance per
* contract to state it differently. An inheritor of this mixin answers a single question instead: which
* registry is mine.
*
* **The authority is the plane's own configuration gate, narrowed to what a fixed signature can carry.**
* The sealed half of that gate is a K-of-N over the registrar role, and its approvals arrive in CALLDATA.
* The rescue entrypoint's signature is shared across every contract on the plane and cannot grow a
* per-contract quorum argument, so what survives into a no-argument `internal view` is MEMBERSHIP: the
* bootstrap admin while the window is open, and afterwards any account the registry currently attests as a
* live registrar.
*
* That is a narrowing — one registrar rather than K of them — and it is deliberate rather than overlooked.
* Two other gates make it safe, and a registrar can widen neither:
*
* - a rescue moves SURPLUS only. Every contract that owes something declares the debt as a reservation,
* and no key reaches behind that line: an intent log's bonds, a billing plane's prepaid credit and a gas
* well's entire float are all unreachable by this surface however it is called.
* - the destination is not the caller's to invent.
*
* A registrar already configures tree writers, thresholds and consumers. An account that can decide who may
* write the account tree is not meaningfully restrained from moving a stray token, so demanding a quorum
* ceremony for the rescue lane would buy nothing and would instead guarantee the lane is never used when it
* is needed. No new role and no new authority pointer is introduced here: the registrar role is the
* registry's own, and membership in it moves in the registry rather than in any contract that reads it.
*
* **The destination is the authority that ordered the rescue.** This state plane has no treasury pointer,
* and adding one would be exactly the new authority this mixin is not allowed to invent — a per-contract
* treasury setter would need its own quorum action on every contract of the plane, to configure something
* the plane has never needed. So the two legitimate destinations are the two addresses already proven: the
* bootstrap admin, and the caller.
*
* The caller is not a free parameter. The rescue entrypoint proves the authority BEFORE it resolves
* destinations, so by the time this mixin is asked, the sender is already either the bootstrap admin or a
* live registrar. Every service on this chain is a Final Wallet with a registered identity and no EOA
* signing key, so the value lands on an account the chain itself attests to. What the gate rules out is the
* thing worth ruling out: a rescue paying an address the plane knows nothing about.
*
* Once the bootstrap window is sealed the admin address is zero, and the base contract refuses a zero
* destination, so the pair collapses to the caller alone — one legitimate destination, which is the case the
* base contract already handles.

/**
* @title FinalPqQuorum
* @notice K-of-N approval where the signatures are post-quantum and the chain
* is what checks them.
*
* @dev This library is the reason Final Chain exists in this design.
*
* `FinalBackend/src/pq/credential.js` carries a rule it had to enforce in code
* because nothing else could: **a surface whose signature is verified on chain
* cannot be PQ.** A co-signer approval reaching `FinalRootAuthority` is checked
* by ECDSA/ERC-1271 in Solidity, so a PQ co-signer would produce approvals the
* contract cannot read, and the quorum would stop reaching threshold with
* nothing in any log naming the cause. `PQ_SURFACE` and `assertBackendVerified`
* exist to keep anyone from crossing that line by accident.
*
* Here the line is gone. The precompiles verify ML-DSA-87 and
* SLH-DSA-SHAKE-256s natively, so a quorum can be PQ *and* on chain, and
* "the backend says these four signatures verified" becomes "these four
* signatures verify, and any node re-derives that independently".
*
* ## Three rules, each closing a specific hole
*
* 1. **Keys come from the registry, never from calldata.** A key passed as an
* argument proves nothing — anyone with a keypair can sign under it. This is
* the difference between a 4-of-5 quorum and a 1-of-1 held by whoever built
* the transaction.
*
* 2. **Signers strictly ascending.** One comparison per entry rejects duplicates
* outright, so a single member cannot supply four approvals and satisfy a
* threshold of four. The alternative — an O(n²) seen-check — is the same
* guarantee with more ways to get it wrong.
*
* 3. **The digest binds chain id and verifying contract.** Without both, an
* approval collected for one contract is replayable against another with the
* same payload shape, and an approval from the test chain is replayable on
* the production one. These co-signers hold one key across environments.
*
* ## Which algorithm
*
* The stack splits its keys by hardness assumption, not by convenience:
* ML-DSA-87 (lattice) signs transactions, SLH-DSA-SHAKE-256s (hash-based) signs
* identity. Two families, so one cryptanalytic result cannot take both.
*
* So an action inherits the class of what it authorizes. Advancing a state root
* is operational and high-cadence: transaction class. Registering or revoking
* an identity is the thing the access class exists for. `ALG_ANY` is available
* and should be used sparingly — accepting either means a break in one family
* takes the quorum.
*
* A MEMBERSHIP action — the registrar quorum that admits, re-roles or revokes
* an identity and upgrades a plane contract — takes both: the ML-DSA-87
* approval and a `seal`, an SLH-DSA-SHAKE-256s signature over the same digest
* by the member's `activeSeal` key. The seal key is its own slot — never the
* access key — so the process that seals cannot also rotate the identity it
* seals for. Every OPERATIONAL action — a bundle root or payload appended to
* the log, a settlement leaf, an account-state write, a tree write, a PHI
* movement — takes the ML-DSA-87 approval alone (the user's ruling of 12 Sep
* 2026, arch/quorum-signing-ml-dsa.md Q1/Q4): the SLH-DSA family is exercised
* at the boundary where a member JOINS — the joiner's own proof of possession
* over the admission digest, verified here through `0x0205` — and by a holder
* on its ledger actions, not on every bundle. An SLH-DSA seal costs a Cloud Run
* co-signer about forty seconds per digest, and the fleet paid it once per
* member per bundle; ML-DSA-87 signs in milliseconds under the key the member
* already votes with.
*
* Every digest binds an `anchorBlock`: the block at which the members read
* tree 1 to decide who is in the round. Binding it means every approval in a
* round was made against ONE roster view, and the window in `require_` means a
* view older than `ANCHOR_WINDOW` blocks is refused rather than honoured.
*
* The practical cost is worth stating: an SLH-DSA signature is 29,792 bytes, so
* a 4-of-5 membership-class quorum is ~119 KB of calldata. That is affordable
* here only because this is our own chain and membership changes are rare. Do
* not carry this pattern to a chain where it is not.

/**
* @title Final State Trees
* @notice Final Chain's state plane: eight fixed-depth Merkle trees, and the rounds that publish all
* eight of their roots as one contemporaneous snapshot.
*
* @dev This contract runs on the project's own reth-based chains and nowhere else. Every signer is
* resolved through an identity registry that verifies post-quantum signatures in precompiles those chains
* alone provide, so a deployment anywhere else cannot authorize a single write. Nothing under
* `contracts/` outside the Final Chain directory imports it, and it takes part in no CREATE2 derivation —
* its address is whatever its deploy transaction produced, never a mined constant that other code pins.
* Gas is deliberately NOT a design constraint here and must not be optimised for: full sibling paths are
* stored, every branch enumerates on chain, and a configuration row keeps its value beside its hash,
* precisely so that no reader ever has to rebuild anything off chain to be sure of it.
*
* **Immutable, and behind no proxy.** There is no upgrade path and no authority that can replace this
* code. Any change to the surface below is a REDEPLOY at a new address, and everything holding the old
* address — the account ledger, the registries, the records contract, every service configured against
* it, every consumer pinning a root — is orphaned the moment that happens and has to be repointed. The
* registry projections into trees 1 and 8 do not travel with a redeploy either: they are derived from the
* registry, so a fresh deployment re-derives them rather than migrating anything.
*
* ## What each tree carries
*
* One tree per domain, because they change at unrelated cadences and a combined tree invalidates every
* outstanding proof on every tick:
*
* | # | tree | holds | cadence |
* |---|---|---|---|
* | 1 | accounts | every Final Wallet's public state | per rotation / creation |
* | 2 | phi | the PHI record: per (wallet, chain) balances, the lock, exposures | per publisher round |
* | 3 | vasset | issued vAsset supply and backing, per (asset, chain) | per settlement |
* | 4 | oracle | published prices and their inputs | ~10 s; 1 s for morph and fee assets |
* | 5 | settlement | chain and asset registry roots | rarely |
* | 6 | allowlist | assets, chains, policy, price sources, DEX deployments | rarely |
* | 7 | intents | intent status, ring-keyed over the posting sequence | per posting |
* | 8 | identity | the wallet-creation admission set, projected from the registry | per identity mutation |
*
* ## Tree 1 is READ, never rebuilt
*
* Tree 1 is a Final Wallet's public state and the SOURCE OF TRUTH every execution chain projects from.
* The sanctioned way to ask it a question is {proofFor} for the sibling path and {liveRoot} for the root
* each chain republishes — {branchProofFor} with {branchRoot} to prove against a branch instead,
* {roundProofFor} with {roundRootAt} to prove against a published round. Those entrypoints are the whole
* interface, and their answers are the only ones that verify.
*
* Do NOT fold the same leaves off chain. This tree is FIXED DEPTH — `DEPTH` levels, with a branch subtree
* at `BRANCH_DEPTH` — zero-padded to that depth, and INSERTION-ORDERED: a key keeps the slot it was first
* handed, permanently, and empty slots hash as the empty subtree rather than being skipped. A rebuild
* that sorts its leaves, or sizes itself `log2(n)` to the number of leaves present, is a DIFFERENT tree.
* Its root is not this root, no proof against it verifies anywhere, and nothing in the failure names the
* cause: the execution chain simply refuses a proof that looks perfectly well formed.
*
* ## Who may write which tree
*
* Four kinds of door, and every tree sits on exactly one of the first three:
*
* - **A service quorum.** {setLeaves} for trees 5 and 6, {setAccountStates} for tree 1: at least
* `threshold[treeId]` approvals from members holding `writerRole[treeId]`, each an ML-DSA-87 vote over
* a digest binding the tree, its nonce and the whole batch. Tree 1's round additionally carries each
* member's SLH-DSA seal, because a leaf there states who an account IS on every chain.
* - **A typed writer.** Trees 2, 3 and 4 are reachable only through {writeTyped}, from the records
* contract, which holds the preimage behind each leaf and computes the hash from it. {setLeaves}
* refuses those three outright, so a stored value can never drift from the commitment beside it.
* - **A writer contract.** `treeWriter[treeId]` writes its tree with no quorum at all: the account ledger
* for tree 1, the intent log for tree 7, the ledger again for tree 8's user admissions. Trees 7 and 8
* have no quorum path whatsoever — {setLeaves} refuses both.
* - **The configuration authority.** Branch 0 of every tree through {setConfig}, plus the pointers,
* rosters and thresholds themselves. Never a tree's own writer or quorum: what a service states is not
* authority over how that service is configured.
*
* `treeWriter[1]` being the account ledger, with no service quorum layered on top, is the design and not
* a gap. A writer contract is not a key: its rules are its bytecode, it has no owner and no proxy, and it
* authorizes every transition by verifying the ACCOUNT HOLDER'S own SLH-DSA credential against the
* commitment this chain holds. That is stronger evidence than a K-of-N of our own services attesting to
* what they read. A quorum on top would be strictly worse than nothing — it would let operators withhold
* approval from a user rotating a stolen key, which is a censorship power over the exact operation the
* account plane exists to make possible.
*
* ## Seeding the chain and asset trees
*
* Trees 5 and 6 are the two a fresh plane cannot infer. Tree 5 carries the settlement chain and asset
* registry roots; tree 6 carries the allowlist those roots stand over — supported chains, supported
* assets, policy, price sources, DEX deployments. Both are quorum-written, and both are expected to be
* SEEDED before the plane is usable: an execution chain copies its chain set and its asset set from these
* roots, so an unseeded pair means every settlement toward a chain is refused at the source and no vAsset
* ever registers. A test plane seeds the test chains; a production plane seeds the production chains and
* their assets. `chainSource` belongs in the same window, because `syncIdentities` derives a service
* account's `deployedChains` table from the enabled chain set, and an unset source quietly produces
* service leaves that exist on Final Chain alone.
*
* The bootstrap ordering is load bearing in one more place: {configureTree} refuses a threshold no live
* roster can meet, so members are registered first and trees configured after. A plane whose trees were
* never configured accepts no quorum write at all while looking perfectly healthy from outside.
*
* ## The hash shape is not a choice
*
* Leaves hash as `keccak256(0x00 ‖ leaf)` and internal nodes as
* `keccak256(0x01 ‖ lo ‖ hi)` with the pair sorted. That is
* `FinalMerkle.verifyTaggedSortedProof`, verbatim, which is what
* `FinalWalletFactory.syncAccountState` and `FinalSettlement` already run on
* every supported chain. A proof produced here is consumed there with no
* translation and no contract change, and tree 1's leaf preimage is exactly
* `FinalWalletFactory.accountStateLeafHash` — same fields, same order, the
* `deployedChains` table `abi.encode`d like every other field.
*
* Getting this wrong is not a compile error anywhere. It is a root every chain
* silently rejects, with nothing pointing at the cause.
*
* ## Positional slots under a sorted-pair tree
*
* Sorted pairs make a proof position-agnostic, which is why it carries no
* direction bits. That does not stop the TREE from being positional, and here
* it is: every key gets a permanent slot, so a single leaf update is `DEPTH`
* hashes instead of a rebuild over every leaf. The verifier neither knows nor
* needs to know that a slot exists.
*
* ## Branches
*
* The slot space of every tree is cut into `BRANCH_COUNT` branches by the top
* `BRANCH_BITS` of the slot: a branch is a subtree with a permanent place, its
* root is one internal node, and a leaf's path to the tree root passes through
* it. Branches hold what belongs to the same domain but not to the same rows
* — branch 0 is the owning service's CONFIGURATION on every tree, tree 8 adds
* the owner → wallets index and the co-signers' slot keys beside the admission
* set — and they are chosen over more trees because a branch shares its
* tree's authority doors and writer, while a tree would need its own. A leaf
* proves against its branch root with `BRANCH_DEPTH` siblings, against the
* tree root with `DEPTH`, against the round root with `ROUND_DEPTH`: one path,
* cut at three heights, one verifier.
*
* ## Rounds, and why the live roots are not the product
*
* `setLeaves` moves a tree. It does not publish one. A consumer that fetched
* eight roots one at a time would get a price proof from one moment and a
* roster proof from another, and something delisted in between would still
* verify.
*
* `publishRound` snapshots all eight together, and folds them into ONE round
* root — the tree roots as the level-`DEPTH` nodes of a depth-`ROUND_DEPTH`
* tree, tree `t` at position `t` — so a single word commits to the whole
* plane and any leaf in it proves against that word with four more siblings.
* A round is the unit a consumer pins, and it is the only thing this contract
* promises is contemporaneous. The execution chains keep anchoring per-tree
* roots (identity, account state, registry roots): those must move at their
* own cadence, not at the oracle's.

* @title Final Sweep
* @notice One sweep surface, on every contract of ours that can end up holding
* an asset it does not owe to anybody.
*
* @dev Assets arrive at protocol contracts that were never meant to hold them:
* a bridge delivers to the wrong leg, a user sends an ERC-20 to a registry, an
* airdrop lands on the gateway, an NFT is safe-transferred into the vault. Left
* alone that value is destroyed. The sweep is how it comes back — and the
* single rule it must never break is that a sweep moves SURPLUS and nothing
* else.
*
* Three seams make that rule per-contract:
*
* - `_requireSweepAuthority()` — the treasury role, expressed in whatever
* access plane the host contract already has (`FinalAccessController` roles,
* a cross-chain authority, a quorum). No new authority is introduced.
* - `_sweepDestinations()` — where a sweep may pay. Ours is a two-address
* answer because a contract normally has exactly two legitimate ones (the
* gateway and the treasury); a contract with one returns it twice.
* `FinalGateway` overrides `_requireSweepDestination` outright: the gateway
* is the drain of the whole system and sweeps ONWARD to anywhere.
* - `_sweepReserved(kind, asset, id)` — the part of the raw balance that is
* NOT surplus: fee deposits, the pending-settlement bucket, searcher
* collateral, settlement custody, vaulted entries, locked PHI. The default
* is zero, which is correct for a contract that custodies nothing; every
* contract that custodies something overrides it and is the one place the
* liability is stated.
*
* The surplus is measured LIVE against the raw balance at call time, so a
* re-entrant destination re-measures against a balance that already fell —
* there is no cached figure to double-spend. Nothing here writes storage, so
* there is no state for a callback to observe half-updated either.
*
* The three ERC-721/ERC-1155 receiver hooks are part of the same surface and
* for the same reason: `safeTransferFrom` reverts into a contract that does not
* answer them, so without these an NFT sent to one of ours does not land at
* all — which is not safety, it is a different way to lose it.

*
* ## Failure is answered, never propagated — and that is deliberate
*
* Every probe here swallows a revert from the address it is probing and answers `false`. The alternative
* is that any address which reverts, runs out of gas in its view, returns malformed data, or simply has
* no code can abort an admission decision that was going to exclude it anyway. That turns a rejected
* candidate into a denial of service: one bad entry in a guardian set would make the whole set
* unevaluable, and an attacker could pick exactly which checks are allowed to complete. Answering false
* keeps the decision in the caller's hands, and every current caller uses these probes to ADMIT, so a
* swallowed failure fails closed.
*
* ## What a caller may and may not conclude
*
* A `true` is a positive statement: the factory named in the call affirmed this address, and for
* {isPqEnabledFinalWallet} the wallet itself affirmed its migration.
*
* A `false` is NOT a statement that the address is not a Final Wallet. It collapses several distinct
* situations into one value — the address genuinely is not registered; the address is registered but its
* code reverted; the call ran out of the gas forwarded to it; the returned data did not decode; the
* supplied `factory` was wrong, unset, or has no code at all. A caller must therefore never read `false`
* as evidence of anything except "not admitted here, now". In particular it must not be used to prove an
* address is safe to treat as an EOA, as a non-wallet, or as outside the system, and it must not be
* cached as a durable classification: the same address can answer differently later, and a wrong
* `factory` makes every answer false without any error being raised.
*
* Anything that must FAIL rather than exclude — an authorization check, a solvency check — has to call
* the factory directly and let the revert propagate.
*
* Pure and view only: this library holds no storage, writes nothing, and emits nothing.

* @title Final Wallet Pointer
* @notice A split reference to a Final Wallet address, for storage layouts that hold one next to small fields.
* @dev Every Final Wallet address is vanity-mined with at least three leading zero bytes, so it carries 136 bits
* of information. Those bits are stored as two fields: {FinalWalletPtr}, the low 128 bits, and
* {FinalWalletPtrHi}, bits 128..135 — the fourth byte from the top. Round-tripping is exact: an address that
* satisfies the invariant splits and joins back to itself.
*
* The gain is layout density. The pair is 17 bytes rather than 20, so it packs alongside a `uint64` and a
* handful of flag bytes inside a single word. On a surface that stores one wallet reference per record, that
* is one `SSTORE` saved per record written and one `SLOAD` per record read.
*
* ## Why two fields and not one `uint136`
*
* The low half is the field every sub-account has held since the four-zero-byte rule. Under that rule the
* high byte was always zero, so a surface that appends {FinalWalletPtrHi} to the free byte after its flags
* keeps every record it already holds readable: the byte reads as zero, which is exactly the value a
* four-zero-byte parent has there. Widening the low field instead would shift every neighbour by a byte and
* make an in-place upgrade misread the flags.
*
* User-defined value types rather than bare `uint128` / `uint8` aliases so the compiler refuses the mix-ups
* this is otherwise prone to: a raw integer cannot be assigned to a pointer field, a pointer cannot be compared
* to an address without an explicit conversion, and arithmetic on it is not defined at all.
*
* ## The invariant is enforced at the boundary, not on every read
*
* {FinalWalletPtrLib.split} is the only construction path that validates, and it reverts rather than
* truncating. Call it at the TRUST BOUNDARY — immediately after the factory has confirmed the address is
* a Final Wallet — so that a non-wallet address fails loudly at the point it enters storage, instead of
* silently becoming a different address that is later read back as authoritative. Nothing downstream
* re-validates, because by then the wrong value would already be indistinguishable from a right one.
*
* Prefer this pair over `address` in new storage layouts for any field that provably holds a Final
* Wallet. Do not use it for a field that may hold an arbitrary address, an EOA, or a controller contract:
* those have no leading-zero guarantee and {FinalWalletPtrLib.split} will reject them.

/**
* @dev Library for reading and writing primitive types to specific storage slots.
*
* Storage slots are often used to avoid storage conflict when dealing with upgradeable contracts.
* This library helps with reading and writing to such slots without the need for inline assembly.
*
* The functions in this library return Slot structs that contain a `value` member that can be used to read or write.
*
* Example usage to set ERC-1967 implementation slot:
* ```solidity
* contract ERC1967 {
* // Define the slot. Alternatively, use the SlotDerivation library to derive the slot.
* bytes32 internal constant _IMPLEMENTATION_SLOT = 0x360894a13ba1a3210667c828492db98dca3e2076cc3735a920a3ca505d382bbc;
*
* function _getImplementation() internal view returns (address) {
* return StorageSlot.getAddressSlot(_IMPLEMENTATION_SLOT).value;
* }
*
* function _setImplementation(address newImplementation) internal {
* require(newImplementation.code.length > 0);
* StorageSlot.getAddressSlot(_IMPLEMENTATION_SLOT).value = newImplementation;
* }
* }
* ```
*
* TIP: Consider using this library along with {SlotDerivation}.
