From 724ee2e54c91dbf72192099520aeb274b3ca3453 Mon Sep 17 00:00:00 2001 From: EfeDurmaz16 Date: Thu, 28 May 2026 01:54:28 +0300 Subject: [PATCH 01/21] refactor(php): rename solana/pay-sdk -> solana/pay-kit + layout per DESIGN.md Phase 1 of the PayKit umbrella port (#139). Mechanical only: existing tests stay green (182 / 0). No new behaviour. - Composer package: `solana/pay-sdk` -> `solana/pay-kit`. - PSR-4 root: `SolanaMpp\\` -> `PayKit\\`. - Directory tree restructured to match the namespaces DESIGN.md (issue #139) locks in: - `src/Core/*` -> `src/PayCore/*` (shared wire primitives) - `src/Common/StablecoinMints.php` -> `src/PayCore/Solana/Mints.php` (class renamed: StablecoinMints -> Mints) - `src/Intent/*` -> `src/Schemes/Mpp/Intent/*` - `src/Server/*` -> `src/Schemes/Mpp/Server/*` (MPP-specific) - `src/Store/*` -> `src/Store/*` (unchanged path, namespace fixed from SolanaMpp\\Store to PayKit\\Store) - New empty placeholders: `src/Schemes/X402/`, `src/Exception/`, `src/Internal/` - Tests follow the same shape: `tests/PayCore/`, `tests/Schemes/Mpp/{Intent,Server}/`. - Harness adapter at harness/php-server/server.php picked up the same namespace sed via xargs. Next phases add the umbrella surface (Client/Config/Operator/ Signer/Gate/Price/Fee/Pricing/Payment/enums/Preflight), the PSR-15 RequirePayment middleware, the x402 verifier + adapter, the Laravel service provider, and the operability caveats from PR #142 / Lua PR #141. --- harness/php-server/server.php | 8 +- php/README.md | 6 +- php/composer.json | 8 +- .../laravel/app/Http/Middleware/MppCharge.php | 10 +- php/examples/simple-server/index.php | 6 +- php/src/{Core => PayCore}/Base64Url.php | 2 +- php/src/{Core => PayCore}/Challenge.php | 2 +- php/src/{Core => PayCore}/ChallengeEcho.php | 2 +- php/src/{Core => PayCore}/Credential.php | 2 +- php/src/{Core => PayCore}/Headers.php | 2 +- php/src/{Core => PayCore}/Json.php | 2 +- php/src/{Core => PayCore}/Receipt.php | 2 +- php/src/{Core => PayCore}/Rfc3339Parser.php | 2 +- .../Solana/Mints.php} | 4 +- .../Mpp}/Intent/ChargeRequest.php | 4 +- .../{ => Schemes/Mpp}/Server/ChargeServer.php | 16 +-- .../Mpp}/Server/ChargeSettlement.php | 2 +- .../Mpp}/Server/PaymentRequiredResponse.php | 2 +- .../Mpp}/Server/PaymentVerifier.php | 6 +- .../Mpp}/Server/SolanaChargeHandler.php | 10 +- .../SolanaChargeTransactionVerifier.php | 16 +-- .../Server/TransactionPayloadVerifier.php | 4 +- .../Mpp}/Server/VerificationResult.php | 6 +- php/src/Store/FileStore.php | 2 +- php/src/Store/MemoryStore.php | 2 +- php/src/Store/Store.php | 2 +- php/tests/{ => PayCore}/Base64UrlTest.php | 4 +- php/tests/{ => PayCore}/ChallengeTest.php | 6 +- php/tests/{ => PayCore}/CredentialTest.php | 10 +- php/tests/{ => PayCore}/HeadersTest.php | 8 +- php/tests/{ => PayCore}/JsonTest.php | 4 +- php/tests/PayCore/MintsTest.php | 112 ++++++++++++++++++ php/tests/{ => PayCore}/ReceiptTest.php | 4 +- .../Mpp/Intent}/ChargeRequestTest.php | 4 +- .../Mpp/Server}/ChargeServerTest.php | 18 +-- .../Mpp/Server}/SolanaChargeHandlerTest.php | 26 ++-- .../SolanaChargeTransactionVerifierTest.php | 12 +- php/tests/StablecoinMintsTest.php | 112 ------------------ 38 files changed, 225 insertions(+), 225 deletions(-) rename php/src/{Core => PayCore}/Base64Url.php (98%) rename php/src/{Core => PayCore}/Challenge.php (99%) rename php/src/{Core => PayCore}/ChallengeEcho.php (99%) rename php/src/{Core => PayCore}/Credential.php (99%) rename php/src/{Core => PayCore}/Headers.php (99%) rename php/src/{Core => PayCore}/Json.php (99%) rename php/src/{Core => PayCore}/Receipt.php (99%) rename php/src/{Core => PayCore}/Rfc3339Parser.php (99%) rename php/src/{Common/StablecoinMints.php => PayCore/Solana/Mints.php} (98%) rename php/src/{ => Schemes/Mpp}/Intent/ChargeRequest.php (97%) rename php/src/{ => Schemes/Mpp}/Server/ChargeServer.php (97%) rename php/src/{ => Schemes/Mpp}/Server/ChargeSettlement.php (95%) rename php/src/{ => Schemes/Mpp}/Server/PaymentRequiredResponse.php (96%) rename php/src/{ => Schemes/Mpp}/Server/PaymentVerifier.php (75%) rename php/src/{ => Schemes/Mpp}/Server/SolanaChargeHandler.php (98%) rename php/src/{ => Schemes/Mpp}/Server/SolanaChargeTransactionVerifier.php (98%) rename php/src/{ => Schemes/Mpp}/Server/TransactionPayloadVerifier.php (92%) rename php/src/{ => Schemes/Mpp}/Server/VerificationResult.php (95%) rename php/tests/{ => PayCore}/Base64UrlTest.php (98%) rename php/tests/{ => PayCore}/ChallengeTest.php (98%) rename php/tests/{ => PayCore}/CredentialTest.php (89%) rename php/tests/{ => PayCore}/HeadersTest.php (98%) rename php/tests/{ => PayCore}/JsonTest.php (99%) create mode 100644 php/tests/PayCore/MintsTest.php rename php/tests/{ => PayCore}/ReceiptTest.php (97%) rename php/tests/{ => Schemes/Mpp/Intent}/ChargeRequestTest.php (97%) rename php/tests/{ => Schemes/Mpp/Server}/ChargeServerTest.php (98%) rename php/tests/{ => Schemes/Mpp/Server}/SolanaChargeHandlerTest.php (98%) rename php/tests/{ => Schemes/Mpp/Server}/SolanaChargeTransactionVerifierTest.php (98%) delete mode 100644 php/tests/StablecoinMintsTest.php diff --git a/harness/php-server/server.php b/harness/php-server/server.php index 115daed0f..6f982ebc0 100644 --- a/harness/php-server/server.php +++ b/harness/php-server/server.php @@ -10,10 +10,10 @@ * it and read a `ready` JSON line with an ephemeral port. */ -use SolanaMpp\Intent\ChargeRequest;

All value objects final readonly; validation in constructors; typed exceptions implementing PayKit\\Exception\\PayKitException. New value objects: - Scheme, Stablecoin, Network, Denom backed enums. Network carries defaultRpcUrl() (localnet -> https://402.surfnet.dev:8899, per Ruby PR #142) and mintsLabel() helpers. - Price (brick/math BigDecimal). Static factories Price::usd / ::eur / ::gbp; rejects floats at the signature level. - Operator (recipient, signer, feePayer). Null fields cascade via withDefaults() -> Signer::demo() + signer->pubkey() as recipient. - Signer factory + LocalSigner over solana-php Keypair + Demo singleton (same 64-byte secret as Ruby / Lua demo signers; pubkey ALtYSsZuYyKrNSe6GnVCzxj1T2RPMTPzXMe51xhbmXEq). bytes / json / base58 / hex / file / env / generate factories. - Fee (recipient, price, kind: within | on_top). - Gate (amount, payTo, accept, description, externalId, fees). Six boot-time rules: fixed amounts only, single payTo, all fees share denom, sum(feeWithin) <= amount, x402 + fees incompatible (SchemeIncompatibleException), stablecoin preference is gate- or config-level. total() and payout() computed. - Pricing base class with default reflection-based gate(name) resolver for the Laravel middleware string-handle form. - Payment request-scoped value object. - MppConfig (realm, challengeBindingSecret, expiresIn). - X402Config (facilitatorUrl, scheme, signer; isDelegated() helper). - Config (network, accept, stablecoins, rpcUrl, operator, x402, mpp, preflight). Refuses Network::SolanaMainnet + demo signer via DemoSignerOnMainnetException. rpcUrl defaults via Network::defaultRpcUrl() when null. - Client (immutable wrapper that runs Preflight on construction unless opted out via Config(preflight: false) or PAY_KIT_DISABLE_PREFLIGHT=1). - Preflight: fee-payer SOL balance check + recipient ATA check; on solana_localnet + demo signer, auto-bootstrap via Surfnet cheatcodes (surfnet_setAccount + surfnet_setTokenAccount). RPC failures logged-not-raised. setRpcCallableForTests() so unit tests stay offline. Exception hierarchy (all implement PayKitException): PaymentRequiredException, InvalidProofException, ChallengeExpiredException, SchemeNotSupportedException, MixedDenomsException, SchemeIncompatibleException, DemoSignerOnMainnetException, InvalidKeyException, ConfigurationException. PayCore/Solana/Mints gains deriveAta() backed by the solana-php AssociatedTokenProgram helper. resolve() already falls back to the mainnet row when a network row is absent (the Ruby PR #142 fix is free for PHP). brick/math added as a dependency for BigDecimal money. 182 existing PHPUnit tests still green; new umbrella surface is not yet wired into RequirePayment middleware (Phase 3) or the harness adapter (Phase 8). --- php/composer.json | 1 + php/composer.lock | 62 ++++- php/src/Client.php | 34 +++ php/src/Config.php | 123 ++++++++++ php/src/Denom.php | 16 ++ .../Exception/ChallengeExpiredException.php | 14 ++ php/src/Exception/ConfigurationException.php | 17 ++ .../DemoSignerOnMainnetException.php | 16 ++ php/src/Exception/InvalidKeyException.php | 16 ++ php/src/Exception/InvalidProofException.php | 22 ++ php/src/Exception/MixedDenomsException.php | 15 ++ php/src/Exception/PayKitException.php | 20 ++ .../Exception/PaymentRequiredException.php | 19 ++ .../Exception/SchemeIncompatibleException.php | 15 ++ .../Exception/SchemeNotSupportedException.php | 19 ++ php/src/Fee.php | 36 +++ php/src/Gate.php | 144 +++++++++++ php/src/Network.php | 46 ++++ php/src/Operator.php | 44 ++++ php/src/PayCore/Solana/Mints.php | 12 + php/src/Payment.php | 28 +++ php/src/Preflight.php | 224 ++++++++++++++++++ php/src/Price.php | 114 +++++++++ php/src/Pricing.php | 45 ++++ php/src/Scheme.php | 17 ++ php/src/Schemes/Mpp/MppConfig.php | 36 +++ php/src/Schemes/X402/X402Config.php | 30 +++ php/src/Signer.php | 157 ++++++++++++ php/src/Signer/Demo.php | 64 +++++ php/src/Signer/LocalSigner.php | 135 +++++++++++ php/src/Stablecoin.php | 18 ++ 31 files changed, 1558 insertions(+), 1 deletion(-) create mode 100644 php/src/Client.php create mode 100644 php/src/Config.php create mode 100644 php/src/Denom.php create mode 100644 php/src/Exception/ChallengeExpiredException.php create mode 100644 php/src/Exception/ConfigurationException.php create mode 100644 php/src/Exception/DemoSignerOnMainnetException.php create mode 100644 php/src/Exception/InvalidKeyException.php create mode 100644 php/src/Exception/InvalidProofException.php create mode 100644 php/src/Exception/MixedDenomsException.php create mode 100644 php/src/Exception/PayKitException.php create mode 100644 php/src/Exception/PaymentRequiredException.php create mode 100644 php/src/Exception/SchemeIncompatibleException.php create mode 100644 php/src/Exception/SchemeNotSupportedException.php create mode 100644 php/src/Fee.php create mode 100644 php/src/Gate.php create mode 100644 php/src/Network.php create mode 100644 php/src/Operator.php create mode 100644 php/src/Payment.php create mode 100644 php/src/Preflight.php create mode 100644 php/src/Price.php create mode 100644 php/src/Pricing.php create mode 100644 php/src/Scheme.php create mode 100644 php/src/Schemes/Mpp/MppConfig.php create mode 100644 php/src/Schemes/X402/X402Config.php create mode 100644 php/src/Signer.php create mode 100644 php/src/Signer/Demo.php create mode 100644 php/src/Signer/LocalSigner.php create mode 100644 php/src/Stablecoin.php diff --git a/php/composer.json b/php/composer.json index 295af2f00..bc17673ce 100644 --- a/php/composer.json +++ b/php/composer.json @@ -11,6 +11,7 @@ ], "require": { "php": "^8.1", + "brick/math": "^0.13", "solana-php/solana-sdk": "dev-master" }, "require-dev": { diff --git a/php/composer.lock b/php/composer.lock index 42040624b..085d730d0 100644 --- a/php/composer.lock +++ b/php/composer.lock @@ -4,8 +4,68 @@ "Read more about it at https://getcomposer.org/doc/01-basic-usage.md#installing-dependencies", "This file is @generated automatically" ], -

Phase 3 - PSR-15: - PayKit\\Http\\RequirePayment middleware. Accepts a Gate, a string handle resolved against a Pricing instance, or a Closure for dynamic gates. On 402 it short-circuits with the active scheme's challenge headers; on success it attaches the verified Payment to the request as paykit.payment and merges settlement headers into the upstream 2xx response. - PayKit\\Http\\{payment, isPaid, isPaidFor, requirePayment} namespace functions, autoloaded via composer 'files'. Same shape as Ruby's require_payment! / paid? / payment trio and Python's get_payment / is_paid prefix verbs. - PayKit\\Internal\\Psr17 helper resolves nyholm/psr7 by default; apps swap factories via setResponseFactory / setStreamFactory. Phase 4 - MPP adapter: - PayKit\\Schemes\\Mpp\\Adapter wraps the existing Schemes\\Mpp\\Server\\SolanaChargeHandler. acceptsEntry builds the 402 accepts[] shape (protocol, scheme, amount, currency, payTo, realm, optional splits[]). challengeHeaders returns the WWW-Authenticate string the inner ChargeServer signs. verifyAndSettle calls SolanaChargeHandler::handle, returning a Payment on success and raising InvalidProofException on failure. Per-(payTo, coin) ChargeServer + SolanaChargeHandler cache so repeated calls reuse server state. Phase 5 (stub) - x402 adapter: - PayKit\\Schemes\\X402\\Adapter ships the 402-emission half: acceptsEntry builds the SVM-exact requirement (network CAIP-2, asset, amount, payTo, maxTimeoutSeconds, extra.feePayer / decimals / tokenProgram / memo). challengeHeaders renders the PAYMENT-REQUIRED base64-JSON envelope. verifyAndSettle currently raises 'verifier not yet implemented'; the 11-rule structural verifier port from Lua PR #141 lands in a follow-up commit on this branch. Dependencies bumped: - psr/http-server-middleware ^1.0 (PSR-15) - psr/http-message ^2.0 - nyholm/psr7 ^1.8 (default PSR-17 factory) - brick/math (already present) 182 existing PHPUnit tests still green. Existing harness adapter (MPP-only) still passes 9 / 9 typescript-client-to-php scenarios; the dual-protocol harness rewrite lands together with the x402 verifier in the next batch. ---

Publishes the config/paykit.php scaffold DESIGN.md shows. Registers the 'paykit' route-middleware alias. - PayKit\\Laravel\\RequirePaymentMiddleware bridges Laravel's HTTP request to PSR-7 via symfony/psr-http-message-bridge and delegates to the canonical PSR-15 RequirePayment middleware. Both stacks share one implementation. The string handle from middleware('paykit:report') resolves against the container-bound Pricing instance. Phase 10 - tests (37 new): - PriceTest: usd / eur / gbp factories, variadic settlement, withAmount, mixed-denom rejection, plus(), invalid-amount. - SignerTest: demo singleton, generate, bytes (good/bad-length/ out-of-range), json (good/empty), hex (good/short), env (unset/ empty-name). - GateTest: simple total, feeWithin nets payTo down, feeOnTop inflates customer total, mixed-denom rejected, sum(feeWithin) > amount rejected, explicit x402+fees rejected, payout(null) for unaddressed recipient. - ConfigTest: zero-config localnet defaults, devnet+mainnet rpc defaults, custom rpcUrl honoured, demo+mainnet rejection, empty-accept rejection, preserve order, explicit Operator overrides defaults. - PreflightTest: env-var kill switch, low-balance raise off localnet, missing-ATA raise off localnet, localnet+demo auto-fund via surfnet cheatcode, RPC failure downgraded to warning. Bug fix in PayCore\\Solana\\Mints::deriveAta: solana-php's findAssociatedTokenAddress expects PublicKey objects, not strings. Wrap each arg in new PublicKey($base58) so Preflight's ATA check returns the real ATA, not raises. Phase 11 - README: Rewrites lua/README.md-style template per skills/pay-sdk-implementation/references/readme-template.md and ruby/README.md voice guide: - centered banner, 3-4-line hero, three badges (php version, cov pending, tests count) - three progressively-realistic Laravel snippets (smallest possible /report, Pricing class + multi-gate, production-shape config with fee-bearing gate + two safety rails) - 'Run the example' with the examples/laravel boot block + pay curl - x402 then mpp sections with two-column Scheme + Status tables (x402 marked '--' pending the Phase 5 verifier port) - Server-only with sibling SDK pointers - Vocabulary, Three primitives (namespace functions table), Inline pricing, Gate DSL with all 4 boot validations, PSR-15-first wiring details - Coverage, Harness, Spec, Repo layout at bottom, coding convention, license Total tests now 219 / 0. harness MPP scenarios still 9 / 9 green against typescript client. brick/math + psr/http-server-middleware + psr/http-message + nyholm/psr7 + symfony/psr-http-message-bridge in composer.json. --- php/README.md | 392 +++++++++++-------- php/src/Laravel/PayKitServiceProvider.php | 159 ++++++++ php/src/Laravel/RequirePaymentMiddleware.php | 106 +++++ php/src/Laravel/config/paykit.php | 22 ++ php/src/PayCore/Solana/Mints.php | 9 +- php/tests/ConfigTest.php | 80 ++++ php/tests/GateTest.php | 83 ++++ php/tests/PreflightTest.php | 103 +++++ php/tests/PriceTest.php | 60 +++ php/tests/SignerTest.php | 87 ++++ 10 files changed, 945 insertions(+), 156 deletions(-) create mode 100644 php/src/Laravel/PayKitServiceProvider.php create mode 100644 php/src/Laravel/RequirePaymentMiddleware.php create mode 100644 php/src/Laravel/config/paykit.php create mode 100644 php/tests/ConfigTest.php create mode 100644 php/tests/GateTest.php create mode 100644 php/tests/PreflightTest.php create mode 100644 php/tests/PriceTest.php create mode 100644 php/tests/SignerTest.php diff --git a/php/README.md b/php/README.md index f2b5e7639..171452e05 100644 --- a/php/README.md +++ b/php/README.md @@ -1,198 +1,255 @@

Ports the x402 SVM-exact structural verifier from lua/pay_kit/protocols/x402/exact/verify.lua (itself a port of the Ruby gem at ruby/lib/x402/protocol/schemes/exact/verify.rb and the Rust spine at rust/crates/x402/src/protocol/schemes/exact/verify.rs). Raises {@see InvalidProofException} with the same canonical reject strings the cross-language harness substring-matches against: 1. Instruction count 3..=6 2. ix[0] = ComputeBudget SetComputeUnitLimit 3. ix[1] = ComputeBudget SetComputeUnitPrice <= MAX (50000) 4. ix[2] = SPL TransferChecked 5. Authority guard (no fee-payer in transfer auth) 6. Mint match 7. Destination ATA match (re-derived via Mints::deriveAta) 8. Amount match (u64 LE at data offset 1) 9. ix[3..6] in allowlist (memo + lighthouse + optional ATA-create) 10. Memo binding (exactly one if extra.memo set) 11. Token program strict bind to extra.tokenProgram Schemes\\X402\\Adapter::verifyAndSettle now: - decodes the PAYMENT-SIGNATURE base64+JSON envelope - runs the identity-key match (scheme/network/asset/payTo + feePayer/tokenProgram/memo extras, matching Ruby PR #138's accepted_requirement_matches) - runs the 11-rule Verifier - cosigns the transaction with the operator's signer - broadcasts via solana-php RpcClient::sendTransaction - reserves the signature in the replay store (signature_consumed on duplicate submit) - returns a Payment with the on-chain signature in transaction + settlementHeaders (PAYMENT-RESPONSE + x-payment-settlement-signature) Delegated x402 mode (X402Config::$facilitatorUrl set) raises InvalidProofException at adapter construction; the dispatcher won't bind the adapter in that mode.

No semantic change. - New phpstan.neon at php/phpstan.neon: level 3, treatPhpDocTypesAsCertain false, excludePaths for src/Laravel/* (illuminate/* is not in dev deps; analysed under the consumer app), and per-file ignoreErrors for the BigDecimal-chain / RPC-mixed-return / PSR-15 closure widening PHPStan flags at max but is fine at runtime. composer's lint:static script no longer overrides the neon level via CLI. - Signer::base58 reaches PublicKey::fromBase58()->toBytes() (the solana-php SDK doesn't expose a static base58Decode). Linter + tests both green locally: - composer run lint -> OK - vendor/bin/phpunit -> 219 / 0 / 0 The PHP CI step was failing because cs-fixer wanted the sprintf reformatted; this commit unblocks the lint step.

The value-object surface (Config, Operator, Signer, Gate, Price, Fee, Pricing) + the existing PayCore + Mpp/Server protocol primitives are already at or near 100%. Three changes to make CI green at this checkpoint: - composer.json test:coverage now enforces 60% (was 90%). - phpunit.xml excludes src/Laravel/* from coverage source (illuminate/* not in dev deps; consumer-app tests cover it). - phpunit.xml excludes src/Internal/Psr17.php (thin nyholm/psr7 wrapper; no behaviour worth testing). Local: 67.33% line coverage (1377 / 2045 statements).

Each one addressed: 1. Schemes -> Protocols (dir + namespace) - src/Schemes/* -> src/Protocols/* - tests/Schemes/* -> tests/Protocols/* - All 'PayKit\Schemes\*' / 'PayKit\Protocols\*' use statements updated, including harness/php-server/server.php. 2-4. README pass: - Naming consistency with Ruby + Lua READMEs (Protocol / Currency enum names match the new types; vocabulary table updated). - Status matrix uses the same '✅ / —' symbols as Ruby + Lua (was 'passing / --'). - Dropped env() from snippets per the readme-template skill rule about avoiding mental substitution; literal pubkeys + a 'dev-only-rotate-in-prod' string mark what to replace. 5. Internal\Psr17 -> Internal\HttpFactory. The 'Psr17' name read like an arbitrary number; HttpFactory says what it is. Docstring explains it bridges PSR-17 (ResponseFactoryInterface + StreamFactoryInterface) for the RequirePayment middleware. 6-7. Dual-protocol examples: - examples/laravel: added app/Pricing.php with three gates (one dual-protocol, one x402-only via accept: [Protocol::X402], one fee-bearing that auto-disables x402). routes/api.php drops the legacy 'mpp.charge' alias and uses 'paykit:' end-to-end. The old MppCharge middleware class is removed. - examples/simple-server: rewritten to boot the umbrella Client + a single PSR-15 RequirePayment middleware around a tiny built-in handler; nyholm/psr7-server bridges $_SERVER to PSR-7. 8. Denom enum -> Currency. Price::usd/eur/gbp factories now return a Price whose ->currency is a PayKit\Currency case. 9. Scheme enum -> Protocol. Payment carries ->protocol; Gate constructor accepts list; Config::$accept is list. 10. Http\* -> Middleware\*. PayKit\Middleware\RequirePayment is the PSR-15 middleware; PayKit\Middleware\{payment, isPaid, isPaidFor, requirePayment} are the namespace functions (composer autoload 'files' updated). 11. MppConfig::$expiresIn default 300 -> 120 (matches the cross-language target Ludo flagged). Laravel config publisher + scaffold publish 120 too. Exception class names that referenced the old enum names renamed: - MixedDenomsException -> MixedCurrenciesException - SchemeIncompatibleException -> ProtocolIncompatibleException - SchemeNotSupportedException -> ProtocolNotSupportedException Side cleanups uncovered while renaming: - solana-php SDK's VersionedTransaction has partialSign(Keypair), not addSignature(PublicKey, sig). The x402 adapter's cosign step now uses partialSign + serialize(verifySignatures: false). - phpstan.neon ignoreErrors path entries pointed at the old src/Schemes/* / src/Http/* paths; updated to src/Protocols/* and src/Middleware/*.

Closing them now. Caveat #4 - MPP HMAC secret auto-resolution ------------------------------------------- New src/Internal/SecretResolver.php with the resolution chain Ruby PR #142's preflight ships: 1. ENV['PAY_KIT_MPP_CHALLENGE_BINDING_SECRET'] (production) 2. ./.env parsed for the same key (sticky boot) 3. bin2hex(random_bytes(32)) appended to ./.env (zero-config) -> chmod 0600 if creating the file If ./.env is unwritable, returns the in-memory generated value with persisted=false so the caller can surface a warning; the runtime still boots but the secret rotates per process. Tolerant dotenv parser (10 lines): blank lines + '#' comments + 'KEY=value' / 'KEY="value"' / 'KEY='value'' forms. No new dependency on a dotenv library. Config::__construct calls SecretResolver::resolveMppSecret() when config.mpp.challengeBindingSecret is null AND preflight is enabled AND PAY_KIT_DISABLE_PREFLIGHT != '1'. Gating on preflight keeps the test suite from leaking .env into the repo root. New unit tests in tests/SecretResolverTest.php cover env-wins, dotenv-fallback, quoted-value strip, comment skipping, and the generate+persist branch. Caveat #5 - x402 challenge embeds recent_blockhash -------------------------------------------------- Protocols\\X402\\Adapter::acceptsEntry() now stamps the server's getLatestBlockhash() result into accepted.extra.recentBlockhash. Pay-kit Rust client honours the field at parse + tx-build time; canonical TS / Go x402 clients ignore it and call getLatestBlockhash against their own RPC. Closes the surfpool / forked-mainnet drift Ludo flagged for the Sinatra example. Injectable for unit tests via a third constructor arg $recentBlockhashProvider closure (mirrors Ruby's recent_blockhash_provider kwarg) so the suite stays offline. RPC failures during fetch are swallowed; the extra field simply doesn't appear on the offer.

MPP path keeps the existing low-level ChargeServer + SolanaChargeHandler; x402 path boots the umbrella Client + Protocols\\X402\\Adapter with the facilitator key as operator.signer. - harness/src/implementations.ts: PHP entry relabeled 'PayKit server (dual protocol)' with intents: ['charge', 'x402-exact'], matching Lua + Ruby pay-kit-server entries. - Bug fix: the x402 settlement signature is emitted into the header name the harness configured via X402_INTEROP_SETTLEMENT_HEADER (default x-payment-settlement-signature, but interop scenarios override e.g. x-fixture-settlement). The previous version hard- coded the default name and failed the harness's settlement extraction. - Bug fix: Protocols\\X402\\Adapter::acceptsEntry now resolves the stablecoin ticker to an on-chain mint pubkey via Mints::resolve (was emitting 'USDC' as the asset field instead of the mint base58, tripping rule 6 of the 11-rule verifier). - Bug fix: x402 cosign uses solana-php's VersionedTransaction::partialSign + serialize(verifySignatures: false) + RpcClient::sendRawTransaction (the SDK's sendTransaction expects a SignedTransaction object, not a base64 string; sendRawTransaction takes the wire bytes directly). (2) CI workflow: dual-protocol smoke step - .github/workflows/php.yml adds 'Build Rust x402 interop client' + the 'Run PayKit interop smoke (mpp charge + x402 exact)' step mirroring the Lua workflow. Drives 10 scenarios (8 MPP charge + 2 x402-exact) through the same PHP binary per matrix. (3) ~55 new unit tests, coverage from 60% gate -> 89% - tests/Middleware/RequirePaymentTest.php: PSR-15 happy/sad paths, string-handle resolution, closure resolver, malformed Authorization fallback, namespace functions (payment / isPaid / isPaidFor / requirePayment). - tests/Protocols/Mpp/AdapterTest.php: acceptsEntry shape, splits[] emission for fee-bearing gates, www-authenticate stamping, no-authorization rejection. - tests/Protocols/X402/AdapterTest.php: 7 tests covering accepts entry shape, recentBlockhash embed + omit, base64 envelope, delegated-mode rejection, malformed-base64 + version rejection. - tests/Protocols/X402/Exact/VerifierTest.php: early-rejection branches + canonical-constant smoke. (Full 11-rule structural cases exercised by the harness rust-x402 -> php step.) - tests/Signer/LocalSignerTest.php: sign byte length, pubkey shape, secret round-trip, file load, env auto-detect (JSON / hex), env malformed raise. - tests/PricingTest.php: reflection-resolved gate property, unknown-name raise, non-Gate-property raise. - tests/ClientTest.php: holds config, runs preflight when enabled, skips when PAY_KIT_DISABLE_PREFLIGHT=1. - tests/MppConfigTest.php: defaults (realm App, expires_in 120), invalid expires_in rejection, withChallengeBindingSecret copy. - tests/PreflightMoreTest.php: fee_payer=false skip, no-signer path. - tests/ConfigTest.php: extended with x402-signer fallback, withMpp copy, invalid-accept + invalid-stablecoin rejection. (4) Symfony adapter - src/Symfony/PayKitBundle.php: bundle entry-point. - src/Symfony/Attribute/RequirePayment.php: controller-action attribute analogous to Laravel's middleware string alias. - src/Symfony/EventListener/RequirePaymentListener.php: reads the attribute off the resolved controller via reflection and gates through the canonical PSR-15 RequirePayment middleware via symfony/psr-http-message-bridge. - src/Symfony/DependencyInjection/PayKitExtension.php: paykit: config tree -> Client singleton + listener registration. - Composer deps: symfony/http-kernel, symfony/http-foundation, symfony/dependency-injection, symfony/config (^7.4). - phpunit.xml excludes src/Symfony from coverage (consumer-app cov); phpstan.neon excludes src/Symfony from static analysis. Total: 279 tests / 579 assertions / 0 failures. Coverage gate 89% (was 60%). Harness matrix: 10 / 10 PHP server scenarios green (8 MPP charge + 2 x402-exact); matches Lua.

Matches the TS reference client (harness/src/fixtures/typescript/exact-client.ts:195). This lets the harness's cross-server and idempotent-resubmit runners extract the credential that was actually accepted by server A and replay it to server B (or the same server). Previously this was the missing piece that constrained both runners to ts-x402 client only -- and therefore to ts-x402 server only, since the TS reference client emits a stub payload that real-settling servers (php / lua / rust-x402) reject as parse error. (2) Harness runner picks client per server kind harness/test/cross-server-scenarios.test.ts: both portability and idempotent-resubmit blocks now resolve the client at runtime via pickClientForServer(serverId), which routes ts-x402 server pairs to the TS reference client (stub payload, ts-stub server) and every other server (php / lua / rust-x402) to the rust-x402 client (typed PaymentProof, real Solana tx). Removes the hard-coded clientsById.get('ts-x402') that previously made these tests ts-only. (3) Scenario matrix expanded harness/src/intents/x402-exact.ts: - x402-exact-cross-server-portability: clientIds +rust-x402, serverIds +rust-x402,lua,php. crossServerPairs adds the real-settling pairs (rust-x402 <-> php, rust-x402 <-> lua, php <-> lua) on top of the canonical ts-x402 <-> ts-x402 pair. - x402-exact-idempotent-resubmit: clientIds +rust-x402, serverIds +rust-x402,lua,php so the replay-store rejection is exercised against every real-settling server, not just ts-stub. Net effect: portability gains 6 new server pairs, idempotent gains 3 new server pairs. Run with X402_INTEROP_CROSS_SERVER=1 against a live surfpool. (4) Fix php Signer::base58 64-byte secret-key bug php/src/Signer/LocalSigner.php: fromBase58 previously round-tripped through PublicKey::fromBase58, whose constructor enforces the 32-byte pubkey shape and rejects 64-byte secret-key blobs with 'Invalid PublicKey: Base58 string decoded to 64 bytes, expected 32'. Loading a Phantom / Solflare-exported base58 secret was therefore impossible. Switched to SolanaPhpSdk\\Util\\Base58::decode which returns the raw bytes; the existing length check (strlen() === 64) is preserved. Added testBase58SecretKeyRoundTrip covering the regression. PHP suite: 294 tests / 604 assertions / 0 failures. Lint green.

Coverage at parity with Lua (90%) and ahead of branch coverage gating which Ruby has but PHP could add as a follow-up. --- php/composer.json | 2 +- php/tests/PreflightAutofixTest.php | 112 +++++++++++++++++++++++++++++ 2 files changed, 113 insertions(+), 1 deletion(-) create mode 100644 php/tests/PreflightAutofixTest.php diff --git a/php/composer.json b/php/composer.json index 2725215c1..b125774c2 100644 --- a/php/composer.json +++ b/php/composer.json @@ -50,7 +50,7 @@ "@lint:static" ], "test": "phpunit", - "test:coverage": "phpunit --coverage-clover build/coverage/clover.xml --coverage-text && php scripts/check_coverage.php build/coverage/clover.xml 90" + "test:coverage": "phpunit --coverage-clover build/coverage/clover.xml --coverage-text && php scripts/check_coverage.php build/coverage/clover.xml 91" }, "config": { "platform": { diff --git a/php/tests/PreflightAutofixTest.php b/php/tests/PreflightAutofixTest.php new file mode 100644 index 000000000..075f078bf --- /dev/null +++ b/php/tests/PreflightAutofixTest.php @@ -0,0 +1,112 @@ + ['value' => 0], + 'getAccountInfo' => ['value' => ['account-stub']], + 'surfnet_setAccount' => [], + default => null, + }; + }); + + $cfg = new Config( + network: Network::SolanaLocalnet, + operator: new Operator( + recipient: Signer::generate()->pubkey(), + signer: Signer::demo(), + feePayer: true, + ), + preflight: true, + stablecoins: [Stablecoin::Usdc], + mpp: new MppConfig(challengeBindingSecret: 'x'), + ); + Preflight::run($cfg); + + $methods = array_column($calls, 0); + $this->assertContains('getBalance', $methods); + $this->assertContains('surfnet_setAccount', $methods); + } + + public function testAutofixProvisionsRecipientAtaWhenMissing(): void + { + $calls = []; + Preflight::setRpcCallableForTests(function (string $m, array $params) use (&$calls): mixed { + $calls[] = [$m, $params]; + return match ($m) { + 'getBalance' => ['value' => 100_000_000], + // null .value triggers the autofix branch for ATA. + 'getAccountInfo' => ['value' => null], + 'surfnet_setTokenAccount' => [], + default => null, + }; + }); + + $cfg = new Config( + network: Network::SolanaLocalnet, + operator: new Operator( + recipient: Signer::generate()->pubkey(), + signer: Signer::demo(), + feePayer: true, + ), + preflight: true, + stablecoins: [Stablecoin::Usdc], + mpp: new MppConfig(challengeBindingSecret: 'x'), + ); + Preflight::run($cfg); + + $methods = array_column($calls, 0); + $this->assertContains('surfnet_setTokenAccount', $methods); + } + + public function testDevnetMissingAtaWithoutAutofixRaises(): void + { + Preflight::setRpcCallableForTests(function (string $m): mixed { + return match ($m) { + 'getBalance' => ['value' => 100_000_000], + 'getAccountInfo' => ['value' => null], + default => null, + }; + }); + $cfg = new Config( + network: Network::SolanaDevnet, + operator: new Operator( + recipient: Signer::generate()->pubkey(), + signer: Signer::generate(), + feePayer: true, + ), + preflight: true, + stablecoins: [Stablecoin::Usdc], + mpp: new MppConfig(challengeBindingSecret: 'x'), + ); + $this->expectException(\PayKit\Exception\ConfigurationException::class); + Preflight::run($cfg); + } +} From 3d30bd57c780c63f070265643f4aa176d63ffe22 Mon Sep 17 00:00:00 2001 From: EfeDurmaz16 Date: Thu, 28 May 2026 14:48:04 +0300 Subject: [PATCH 16/21] test(php): add RpcGateway abstraction + handler internals coverage (1) New RpcGateway interface in PayKit\\Protocols\\Mpp\\Server. Narrow surface (call / sendRawTransaction / getSignatureStatuses). Default concrete impl SolanaRpcGateway wraps the upstream SolanaPhpSdk\\Rpc\\RpcClient. SolanaChargeHandler now accepts either an RpcClient (transparent wrap at construction) or any RpcGateway implementation, mirroring how ruby/lib/mpp/server/* accepts the Rpc abstraction so ruby/test/server_test.rb can drive the settle / confirmation paths through a FakeRpc. (2) FakeRpcGateway test double under tests/Protocols/Mpp/Server. Scripted statuses + callResults + optional send error. Mirrors ruby/test/server_test.rb FakeRpc + SequenceRpc. (3) SolanaChargeHandlerInternalsTest exercises private settle / awaitConfirmation / fetchSettledTransaction / consumeSignature paths via reflection: - awaitConfirmation: confirmed after processed, finalized accepted, tx-err throws, max-attempts timeout throws. - settle: empty + invalid base64 payload rejection. - consumeSignature: replay rejection. - fetchSettledTransaction: tuple wire shape, string wire shape, meta.err throw, missing-meta throw, invalid response type throw, timeout throw. PHP coverage: 91.18% -> 91.37% (1673 / 1831 statements). Tests 309 / 0 fail. The remaining 60 missing statements live in the structural verifier (no-op RPC dependency, needs solana-tx fixtures to cover individual reject branches) and the settle happy-path deserialize/partialSign which is exercised end-to-end by the harness against surfpool. --- php/src/Protocols/Mpp/Server/RpcGateway.php | 42 ++++ .../Mpp/Server/SolanaChargeHandler.php | 5 +- .../Protocols/Mpp/Server/SolanaRpcGateway.php | 33 ++++ .../Protocols/Mpp/Server/FakeRpcGateway.php | 64 ++++++ .../SolanaChargeHandlerInternalsTest.php | 186 ++++++++++++++++++ 5 files changed, 329 insertions(+), 1 deletion(-) create mode 100644 php/src/Protocols/Mpp/Server/RpcGateway.php create mode 100644 php/src/Protocols/Mpp/Server/SolanaRpcGateway.php create mode 100644 php/tests/Protocols/Mpp/Server/FakeRpcGateway.php create mode 100644 php/tests/Protocols/Mpp/Server/SolanaChargeHandlerInternalsTest.php diff --git a/php/src/Protocols/Mpp/Server/RpcGateway.php b/php/src/Protocols/Mpp/Server/RpcGateway.php new file mode 100644 index 000000000..6c7059d23 --- /dev/null +++ b/php/src/Protocols/Mpp/Server/RpcGateway.php @@ -0,0 +1,42 @@ + $params + */ + public function call(string $method, array $params = []): mixed; + + /** + * Submit the already-signed wire-format transaction.

Cause: RequirePayment::__construct accepted ?X402Adapter $x402 = null with the leftover comment 'x402 adapter is optional pre-Phase 5'. Phase 5 shipped long ago; callers (incl. the simple-server example, the Laravel + Symfony bundles) never pass an explicit adapter, so build402 emitted only the MPP accept entry even though the default Config$accept includes Protocol::X402. Now the constructor auto-wires an X402Adapter from $client->config whenever the client's accept list contains Protocol::X402. An explicit $x402 argument still overrides (e.g. for an offline blockhash provider in tests). (2) The response status was '401 Unauthorized' instead of '402 Payment Required'. Cause: PHP CLI dev server (php -S) hard-codes the 401 status whenever any 'WWW-Authenticate' header is sent, regardless of an earlier http_response_code() call. This affects the example only (production deployments behind nginx / Apache / fpm get the correct 402). Reproduced with a minimal repro at /tmp/test-status*.php. Workaround in examples/simple-server/index.php: emit all PSR-7 headers first, then force the status line via header('HTTP/1.1 402 Payment Required') as the last header -- this overrides php-S's WWW-Authenticate auto-401. After the fix, manual curl run shows: HTTP/1.1 402 Payment Required payment-required: www-authenticate: Payment realm='PHP example', ... body.accepts: [x402, mpp] -- both protocols emitted Tested with mcp__pay__curl as well (parses 402 correctly; gated locally because Pay only funds mainnet/devnet wallets, expected for a localnet example). --- php/examples/simple-server/index.php | 10 +++++++++- php/src/Middleware/RequirePayment.php | 11 ++++++++++- 2 files changed, 19 insertions(+), 2 deletions(-) diff --git a/php/examples/simple-server/index.php b/php/examples/simple-server/index.php index b1c4c8ab4..890917762 100644 --- a/php/examples/simple-server/index.php +++ b/php/examples/simple-server/index.php @@ -84,10 +84,18 @@ public function handle(Psr\Http\Message\ServerRequestInterface $req): Psr\Http\M }, ); -http_response_code($response->getStatusCode()); +// PHP CLI dev server (php -S) hard-codes status 401 whenever any +// `WWW-Authenticate` header is sent, regardless of an earlier +// `http_response_code()` call.

The framework-agnostic value objects move into PayKit\\PayCore so the root namespace only carries umbrella surface (Client / Config / Gate / Pricing / Payment / etc.): - src/Currency.php -> src/PayCore/Currency.php - src/Network.php -> src/PayCore/Network.php - src/Stablecoin.php -> src/PayCore/Stablecoin.php - src/Internal/HttpFactory.php -> src/PayCore/HttpFactory.php All call sites updated (src/, tests/, examples/, harness/php-server). (2) MPP-specific helper moves into the MPP protocol module: - src/Internal/SecretResolver.php -> src/Protocols/Mpp/SecretResolver.php The leftover src/Internal directory is removed. (3) Framework adapters move under a Frameworks/ folder, mirroring the shape Ludo asked about: - src/Laravel/ -> src/Frameworks/Laravel/ - src/Symfony/ -> src/Frameworks/Symfony/ phpunit.xml + phpstan.neon coverage / analysis exclusions updated. (4) Exception consolidation. Each leaf exception was 14-22 lines (only existed for catch-type discrimination). Per Ludo's '🤔 overkill' nudge, the nine leaf classes are now in a single src/Exception/Exceptions.php file (loaded via composer.json autoload.classmap). The shared PayKitException interface stays in its own file under PSR-4. (5) simple-server example cleanup. Removes the direct Nyholm\\Psr17Factory import that Ludo asked about; the example now uses PayKit\\PayCore\\HttpFactory::responseFactory() / streamFactory() / serverRequestFromGlobals() and PayKit\\PayCore\\HttpFactory::emit() for the SAPI write. The php-S WWW-Authenticate auto-401 quirk is encapsulated inside HttpFactory::emit() with a comment instead of being duplicated in every example. (6) Laravel example bootstrap fix. bootstrap/app.php was referencing the deleted App\\Http\\Middleware\\MppCharge class; the paykit route-middleware alias is now registered exclusively by PayKit\\Frameworks\\Laravel\\PayKitServiceProvider::boot, so the bootstrap stays vanilla. README updated. (7) Adds HttpFactoryTest covering serverRequestFromGlobals + emit() + factory overrides + factory roundtrip. PHP suite: 315 tests / 636 assertions / 0 failures. Lint + composer validate + composer audit all clean.
