+//! BBS — Broadcast Blanket Service for background and broadcast music licensing.
+//!
+//! The Broadcast Blanket Service provides:
+//!   - Background music blanket licences for public premises (restaurants,
+//!     hotels, retail, gyms, broadcast stations, streaming platforms).
+//!   - Per-broadcast cue sheet reporting for TV, radio, and online broadcast.
+//!   - Integration with PRO blanket licence pools (PRS, ASCAP, BMI, SOCAN,
+//!     GEMA, SACEM, and 150+ worldwide collection societies).
+//!   - Real-time broadcast monitoring data ingestion (BMAT, MEDIAGUARD feeds).
+//!
+//! BBS connects to the Retrosync collection society registry to route royalties
+//! automatically to the correct PRO/CMO in each territory based on:
+//!   - Work ISWC + territory → mechanical/performance split
+//!   - Recording ISRC + territory → neighbouring rights split
+//!   - Society agreement priority (reciprocal agreements map)
+//!
+//! LangSec:
+//!   - All ISRCs/ISWCs validated before cue sheet generation.
+//!   - Station/venue identifiers limited to 100 chars, ASCII-safe.
+//!   - Broadcast duration: u32 seconds, max 7200 (2 hours per cue).
+//!   - Cue sheet batches: max 10,000 lines per submission.

+//! BWARM — Best Workflow for All Rights Management.
+//!
+//! BWARM is the IASA (International Association of Sound and Audiovisual Archives)
+//! recommended workflow standard for archiving and managing audiovisual content
+//! with complete rights metadata throughout the content lifecycle.
+//!
+//! Reference: IASA-TC 03, IASA-TC 04, IASA-TC 06 (Rights Management)
+//!            https://www.iasa-web.org/technical-publications
+//!
+//! This module provides:
+//!   1. BWARM rights record model (track → work → licence chain).
+//!   2. Rights lifecycle state machine (unregistered → registered → licensed → distributed).
+//!   3. Rights conflict detection (overlapping territories / periods).
+//!   4. BWARM submission document generation (XML per IASA schema).
+//!   5. Integration with ASCAP, BMI, SoundExchange, The MLC for rights confirmation.
+//!
+//! LangSec: all text fields sanitised; XML output escaped via xml_escape().

+//! CMRRA — Canadian Musical Reproduction Rights Agency.
+//!
+//! CMRRA (https://www.cmrra.ca) is Canada's primary mechanical rights agency,
+//! administering reproduction rights for music used in:
+//!   - Physical recordings (CDs, vinyl, cassettes)
+//!   - Digital downloads (iTunes, Beatport, etc.)
+//!   - Streaming (Spotify, Apple Music, Amazon Music, etc.)
+//!   - Ringtones and interactive digital services
+//!
+//! CMRRA operates under Section 80 (private copying) and Part VIII of the
+//! Canadian Copyright Act, and partners with SODRAC for Quebec repertoire.
+//! Under the CMRRA-SODRAC Processing (CSI) initiative it issues combined
+//! mechanical + reprographic licences to Canadian DSPs and labels.
+//!
+//! This module provides:
+//!   - CMRRA mechanical licence request generation
+//!   - CSI blanket licence rate lookup (CRB Canadian equivalent)
+//!   - Quarterly mechanical royalty statement parsing
+//!   - CMRRA registration number validation
+//!   - DSP reporting file generation (CSV per CMRRA spec)
+//!
+//! LangSec:
+//!   - All ISRCs/ISWCs validated by shared parsers before submission.
+//!   - CMRRA registration numbers: 7-digit numeric.
+//!   - Monetary amounts: f64 but capped at CAD 1,000,000 per transaction.
+//!   - All CSV output uses RFC 4180 + CSV-injection prevention.

+//!   - Charge status polling
+//!   - Payment event handling (CONFIRMED → trigger royalty release)
+//!
+//! Security:

+//! DDEX Gateway — automated ERN (push) and DSR (pull) cycles.
+//!
+//! V-model (GMP/GLP) approach:
+//!   Every operation is a named, sequenced "Gateway Event" with an ISO-8601 timestamp
+//!   and a monotonic sequence number.  Events are stored in the audit log and can be
+//!   used by auditors to prove "track X was delivered to DSP Y at time T, and revenue
+//!   from DSP Y was ingested at time T+Δ."
+//!
+//! ERN Push cycle:
+//!   1. Collect pending release metadata from the pending queue.
+//!   2. Build DDEX ERN 4.1 XML (using ddex::build_ern_xml_with_contributors).
+//!   3. Write XML to a staging directory.
+//!   4. SFTP PUT to each configured DSP endpoint.
+//!   5. Record TransferReceipt in the audit log.
+//!   6. Move staging file to a "sent" archive.
+//!
+//! DSR Pull cycle:
+//!   1. SFTP LIST the DSP drop directory.
+//!   2. For each new file: SFTP GET → local temp dir.
+//!   3. Parse with dsr_parser::parse_dsr_file.
+//!   4. Emit per-ISRC royalty totals to the royalty pipeline.
+//!   5. (Optionally) delete or archive the remote file.
+//!   6. Record audit event.

+//! DQI — Data Quality Initiative.
+//!
+//! The Data Quality Initiative (DQI) is a joint DDEX / IFPI / RIAA / ARIA
+//! programme that scores sound recording metadata quality and flags records
+//! that fail to meet delivery standards required by DSPs, PROs, and the MLC.
+//!
+//! Reference: DDEX Data Quality Initiative v2.0 (2022)
+//!            https://ddex.net/implementation/data-quality-initiative/
+//!
+//! Scoring model:
+//!   Each field is scored 0 (absent/invalid) or 1 (present/valid).
+//!   The total score is expressed as a percentage of the maximum possible score.
+//!   DQI tiers:
+//!     Gold   ≥ 90%  — all DSPs will accept; DDEX-ready
+//!     Silver ≥ 70%  — accepted by most DSPs with caveats
+//!     Bronze ≥ 50%  — accepted by some DSPs; PRO delivery may fail
+//!     Below  < 50%  — reject at ingestion; require remediation
+//!
+//! LangSec: DQI scores are always server-computed — never trusted from client.

+// ── dsr_parser.rs ─────────────────────────────────────────────────────────────
+//! DDEX DSR 4.1 (Digital Sales Report) flat-file ingestion.
+//!
+//! Each DSP (Spotify, Apple Music, Amazon, YouTube, Tidal, Deezer…) delivers
+//! a tab-separated or comma-separated flat-file containing per-ISRC, per-territory
+//! streaming/download counts and revenue figures.
+//!
+//! This module:
+//!   1. Auto-detects the DSP dialect from the header row.
+//!   2. Parses every data row into a `DsrRecord`.
+//!   3. Aggregates records into a `DsrReport` keyed by (ISRC, territory, service).
+//!   4. Supports multi-sheet files (some DSPs concatenate monthly + quarterly sheets
+//!      with a blank-line separator).
+//!
+//! GMP/GLP: every parsed row is checksummed; the report carries a total row-count,
+//! rejected-row count, and parse timestamp so auditors can prove completeness.

+//! Global Trade Management System (GTMS) integration.
+//!
+//! Scope for a digital music platform:
+//!   • Work classification: ECCN (Export Control Classification Number) and
+//!     HS code assignment for physical merch, recording media, and digital goods.
+//!   • Distribution screening: cross-border digital delivery routed through
+//!     GTMS sanctions/embargo checks before DSP delivery or society submission.
+//!   • Export declaration: EEI (Electronic Export Information) stubs for
+//!     physical shipments (vinyl pressings, merch) via AES / CBP ACE.
+//!   • Denied Party Screening (DPS): checks payees against:
+//!       – OFAC SDN / Consolidated Sanctions List
+//!       – EU Consolidated List (EUR-Lex)
+//!       – UN Security Council sanctions
+//!       – UK HM Treasury financial sanctions
+//!       – BIS Entity List / Unverified List
+//!   • Incoterms 2020 annotation on physical shipments.
+//!
+//! Integration targets:
+//!   • SAP GTS (Global Trade Services) via RFC/BAPI or REST API
+//!     (SAP_GTS_SANCTIONS / SAP_GTS_CLASSIFICATION OData services).
+//!   • Thomson Reuters World-Check / Refinitiv (REST) — DPS fallback.
+//!   • US Census Bureau AES Direct (EEI filing).
+//!   • EU ICS2 (Import Control System 2) for EU entry declarations.
+//!
+//! Zero Trust: all GTMS API calls use mTLS client cert.
+//! LangSec: all HS codes validated against 6-digit WCO pattern.
+//! ISO 9001 §7.5: all screening results and classifications logged.

+#![allow(dead_code)] // Script detection module: full language validation API exposed
+//! Hyperglot — Unicode script and language detection for multilingual metadata.
+//!
+//! Implements ISO 15924 script code detection using pure-Rust Unicode ranges.
+//! Hyperglot (https://hyperglot.rosettatype.com) identifies languages from
+//! writing systems; this module provides the same service without spawning
+//! an external Python process.
+//!
+//! LangSec:
+//!   All inputs are length-bounded (max 4096 codepoints) before scanning.
+//!   Script detection is done via Unicode block ranges — no regex, no exec().
+//!
+//! Usage:
+//!   let result = detect_scripts("Hello мир 日本語");
+//!   // → [Latin (95%), Cyrillic (3%), CJK (2%)]

+//! (persons and organisations) that participate in the creation,
+//! production, management, and distribution of intellectual property.
+//!
+//! In the music industry ISNI is used to:
+//!   - Unambiguously identify composers, lyricists, performers, publishers,
+//!     record labels, and PROs across databases.
+//!   - Disambiguate name-matched artists in royalty systems.
+//!   - Cross-reference with IPI, ISWC, ISRC, and Wikidata QID.
+//!
+//! Reference: https://isni.org / https://www.iso.org/standard/44292.html
+//!
+//! LangSec:
+//!   - ISNI always 16 digits (last may be 'X' for check digit 10).
+//!   - Validated via ISO 27729 MOD 11-2 check algorithm before any lookup.
+//!   - All outbound ISNI.org API calls length-bounded and JSON-sanitised.

+#![allow(dead_code)] // Security boundary module: exposes full validation API surface
+//! LangSec — Language-Theoretic Security threat model and defensive parsing.
+//!
+//! Langsec (https://langsec.org) treats all input as a formal language and
+//! requires that parsers accept ONLY the valid subset, rejecting everything
+//! else at the boundary before any business logic runs.
+//!
+//! This module:
+//!   1. Documents the threat model for every external input surface.
+//!   2. Provides nom-based all-consuming recognisers for all identifier types
+//!      not already covered by shared::parsers.
+//!   3. Provides a unified `validate_input` gateway used by route handlers
+//!      as the single point of LangSec enforcement.
+//!
+//! Design rules (enforced here):
+//!   - All recognisers use nom::combinator::all_consuming — partial matches fail.
+//!   - No regex — regexes have ambiguous failure modes; nom's typed combinators
+//!     produce explicit, structured errors.
+//!   - Input length is checked BEFORE parsing — unbounded input = DoS vector.
+//!   - Control characters outside the ASCII printable range are rejected.
+//!   - UTF-8 is validated by Rust's str type; invalid UTF-8 never reaches here.
+use serde::Serialize;
+use tracing::warn;

+//! Multi-sig vault integration for artist royalty payouts.
+//!
+//! Pipeline:
+//!   DSP revenue (USD) → business bank → USDC stablecoin → Safe multi-sig vault
+//!   Smart contract conditions checked → propose Safe transaction → artist wallets
+//!
+//! Implementation:
+//!   - Uses the Safe{Wallet} Transaction Service REST API (v1)
+//!     <https://docs.safe.global/api-overview/transaction-service>
+//!   - Supports Ethereum mainnet, Polygon, Arbitrum, and BTTC (custom Safe instance)
+//!   - USDC balance monitoring via a standard ERC-20 `balanceOf` RPC call
+//!   - Smart contract conditions: minimum balance threshold, minimum elapsed time
+//!     since last distribution, and optional ZK proof of correct split commitment
+//!
+//! GMP note: every proposed transaction is logged with a sequence number.
+//! The sequence is the DDEX-gateway audit event number, providing a single audit
+//! trail from DSR ingestion → USDC conversion → Safe proposal → on-chain execution.

+//! NFT Shard Manifest — metadata-first, ownership-first shard access model.
+//!
+//! Architecture (revised from previous degraded-audio approach):
+//!   • Music shards live on BTFS and are *publicly accessible*.
+//!   • NFT (on BTTC) holds the ShardManifest: ordered CIDs, assembly instructions,
+//!     and an optional AES-256-GCM key for tracks that choose at-rest encryption.
+//!   • Public listeners can see fragments (unordered shards) but only NFT holders
+//!     can reconstruct the complete, coherent track.
+//!   • ZK proofs verify NFT ownership + correct assembly without revealing keys publicly.
+//!
+//! ShardManifest fields:
+//!   track_cid      — BTFS CID of the "root" track object (JSON index)
+//!   shard_order    — ordered list of BTFS shard CIDs  (assembly sequence)
+//!   shard_count    — used for completeness verification
+//!   enc_key_hex    — optional AES-256-GCM key (present only if encrypted shards)
+//!   nonce_hex      — AES-GCM nonce
+//!   version        — manifest schema version
+//!   isrc           — ISRC of the track this manifest covers
+//!   zk_commit_hash — SHA-256 of (shard_order || enc_key_hex) for ZK circuit input
+//!
+//! GMP note: the manifest itself is the "V-model verification artifact" —
+//! it proves the assembled track is correct and complete.

+//! SSH/SFTP transport layer for DDEX Gateway.
+//!
+//! Production path: delegates to the system `sftp` binary (OpenSSH) via
+//! `tokio::process::Command`.  This avoids C-FFI dependencies and works on any
+//! Linux/NixOS host where openssh-client is installed.
+//!
+//! Dev path (SFTP_DEV_MODE=1): all operations are performed on the local
+//! filesystem under `SFTP_DEV_ROOT` (default `/tmp/sftp_dev`).
+//!
+//! GMP/GLP note: every transfer returns a `TransferReceipt` with an ISO-8601
+//! timestamp, byte count, and SHA-256 digest of the transferred payload so that
+//! the audit log can prove "file X was delivered unchanged to DSP Y at time T."

+//! Music shard module — CFT decomposition of audio metadata into DA51 CBOR shards.
+//!
+//! Scale tower for music (mirrors erdfa-publish text CFT):
+//!   Track → Stem → Segment → Frame → Sample → Byte
+//!
+//! Shards are semantic representations of track structure encoded as DA51-tagged
+//! CBOR bytes using the erdfa-publish library.
+//!
+//! ## NFT gating model (updated)
+//!
+//! Shard DATA is **fully public** — `GET /api/shard/:cid` returns the complete shard
+//! to any caller without authentication.  This follows the "public DA" (decentralised
+//! availability) model: the bits are always accessible on BTFS.
+//!
+//! NFT ownership gates only the **ShardManifest** (assembly instructions) served via
+//! `GET /api/manifest/:token_id`.  A wallet that holds the NFT can request the
+//! ordered CID list + optional AES-256-GCM decryption key for the assembled track.
+//!
+//! Pre-generated source shards (Emacs Lisp / Fractran VM reflections of each
+//! Rust module) live in `shards/` at the repo root and can be served directly
+//! via GET /api/shard/:cid once indexed at startup or via POST /api/shard/index.

+//! Wallet challenge-response authentication.
+//!
+//! Flow:
+//!   1. Client: GET /api/auth/challenge/{address}
+//!      Server issues a random nonce with 5-minute TTL.
+//!
+//!   2. Client signs the nonce string with their wallet private key.
+//!      - BTTC / EVM wallets: personal_sign (EIP-191 prefix)
+//!      - TronLink on Tron: signMessageV2
+//!
+//!   3. Client: POST /api/auth/verify { challenge_id, address, signature }
+//!      Server recovers the signer address from the ECDSA signature and
+//!      checks it matches the claimed address.  On success, issues a JWT
+//!      (`sub` = wallet address, `exp` = 24h) the client stores and sends
+//!      as `Authorization: Bearer <token>` on all subsequent API calls.
+//!
+//! Security properties:
+//!   - Nonce is cryptographically random (OS entropy via /dev/urandom).
+//!   - Challenges expire after 5 minutes → replay window is bounded.
+//!   - Used challenges are deleted immediately → single-use.
+//!   - JWT signed with HMAC-SHA256 using JWT_SECRET env var.

+//!      (namespace: https://retrosync.media/xml/cwr/1) via `to_canonical_xml()`.
+//!   2. The canonical XML document is transformed by the appropriate `.xsl`
+//!      stylesheet loaded from `XSLT_DIR` (default: `backend/xslt_transforms/`).
+//!   3. The `xot` crate provides pure-Rust XSLT 1.0 + XPath 1.0 processing —
+//!      no libxslt/libxml2 C dependency.
+//!
+//! HTTP API:
+//!   POST /api/royalty/xslt/:society   — body: JSON WorkRegistration array
+//!                                        returns: Content-Type: application/xml
+//!   POST /api/royalty/xslt/all        — returns: ZIP of all society XMLs

+                  At RetroSync, our mission is deeply personal, born from a five-year journey navigating the music industry from an artist's perspective. As a professional artist and a dedicated mother, I've experienced firsthand the frustration of unreceived or lost payments — a reality that stifles creativity and makes sustainable careers incredibly challenging.

+                <p>
+                  Fueled by this passion for fairness and a deep understanding of artists' needs, RetroSync was conceived. We are building a transparent, artist-centric platform designed to empower creators. Our goal is to ensure artists are compensated fairly and equitably, putting control back into their hands.

+## Contributing to Foundry
+
+Thanks for your interest in improving Foundry!
+
+There are multiple opportunities to contribute at any level. It doesn't matter if you are just getting started with Rust or are the most weathered expert, we can use your help.
+
+This document will help you get started. **Do not let the document intimidate you**.
+It should be considered as a guide to help you navigate the process.
+
+The [dev Telegram][dev-tg] is available for any concerns you may have that are not covered in this guide.
+
+### Code of Conduct
+
+The Foundry project adheres to the [Rust Code of Conduct][rust-coc]. This code of conduct describes the _minimum_ behavior expected from all contributors.
+
+Instances of violations of the Code of Conduct can be reported by contacting the team at [me@gakonst.com](mailto:me@gakonst.com).
+
+### Ways to contribute
+
+There are fundamentally four ways an individual can contribute:
+
+1. **By opening an issue:** For example, if you believe that you have uncovered a bug
+   in Foundry, creating a new issue in the issue tracker is the way to report it.
+2. **By adding context:** Providing additional context to existing issues,
+   such as screenshots and code snippets, which help resolve issues.
+3. **By resolving issues:** Typically this is done in the form of either
+   demonstrating that the issue reported is not a problem after all, or more often,
+   by opening a pull request that fixes the underlying problem, in a concrete and
+   reviewable manner.
+
+**Anybody can participate in any stage of contribution**. We urge you to participate in the discussion
+around bugs and participate in reviewing PRs.
+
+### Contributions Related to Spelling and Grammar
+
+At this time, we will not be accepting contributions that only fix spelling or grammatical errors in documentation, code or
+elsewhere.
+
+### Asking for help
+
+If you have reviewed existing documentation and still have questions, or you are having problems, you can get help in the following ways:
+
+-   **Asking in the support Telegram:** The [Foundry Support Telegram][support-tg] is a fast and easy way to ask questions.
+-   **Opening a discussion:** This repository comes with a discussions board where you can also ask for help. Click the "Discussions" tab at the top.
+
+As Foundry is still in heavy development, the documentation can be a bit scattered.
+The [Foundry Book][foundry-book] is our current best-effort attempt at keeping up-to-date information.
+
+### Submitting a bug report
+
+When filing a new bug report in the issue tracker, you will be presented with a basic form to fill out.
+
+If you believe that you have uncovered a bug, please fill out the form to the best of your ability. Do not worry if you cannot answer every detail; just fill in what you can. Contributors will ask follow-up questions if something is unclear.
+
+The most important pieces of information we need in a bug report are:
+
+-   The Foundry version you are on (and that it is up to date)
+-   The platform you are on (Windows, macOS, an M1 Mac or Linux)
+-   Code snippets if this is happening in relation to testing or building code
+-   Concrete steps to reproduce the bug
+
+In order to rule out the possibility of the bug being in your project, the code snippets should be as minimal
+as possible. It is better if you can reproduce the bug with a small snippet as opposed to an entire project!
+
+See [this guide][mcve] on how to create a minimal, complete, and verifiable example.
+
+### Submitting a feature request
+
+When adding a feature request in the issue tracker, you will be presented with a basic form to fill out.
+
+Please include as detailed of an explanation as possible of the feature you would like, adding additional context if necessary.
+
+If you have examples of other tools that have the feature you are requesting, please include them as well.
+
+### Resolving an issue
+
+Pull requests are the way concrete changes are made to the code, documentation, and dependencies of Foundry.
+
+Even minor pull requests, such as those fixing wording, are greatly appreciated. Before making a large change, it is usually
+a good idea to first open an issue describing the change to solicit feedback and guidance. This will increase
+the likelihood of the PR getting merged.
+
+Please make sure that the following commands pass if you have changed the code:
+
+```sh
+forge fmt --check
+forge test -vvv
+```
+
+To make sure your changes are compatible with all compiler version targets, run the following commands:
+
+```sh
+forge build --skip test --use solc:0.6.2
+forge build --skip test --use solc:0.6.12
+forge build --skip test --use solc:0.7.0
+forge build --skip test --use solc:0.7.6
+forge build --skip test --use solc:0.8.0
+```
+
+The CI will also ensure that the code is formatted correctly and that the tests are passing across all compiler version targets.
+
+#### Adding cheatcodes
+
+Please follow the guide outlined in the [cheatcodes](https://github.com/foundry-rs/foundry/blob/master/docs/dev/cheatcodes.md#adding-a-new-cheatcode) documentation of Foundry.
+
+When making modifications to the native cheatcodes or adding new ones, please make sure to run [`./scripts/vm.py`](./scripts/vm.py) to update the cheatcodes in the [`src/Vm.sol`](./src/Vm.sol) file.
+
+By default the script will automatically generate the cheatcodes from the [`cheatcodes.json`](https://raw.githubusercontent.com/foundry-rs/foundry/master/crates/cheatcodes/assets/cheatcodes.json) file but alternatively you can provide a path to a JSON file containing the Vm interface, as generated by Foundry, with the `--from` flag.
+
+```sh
+./scripts/vm.py --from path/to/cheatcodes.json
+```
+
+It is possible that the resulting [`src/Vm.sol`](./src/Vm.sol) file will have some changes that are not directly related to your changes, this is not a problem.
+
+#### Commits
+
+It is a recommended best practice to keep your changes as logically grouped as possible within individual commits. There is no limit to the number of commits any single pull request may have, and many contributors find it easier to review changes that are split across multiple commits.
+
+That said, if you have a number of commits that are "checkpoints" and don't represent a single logical change, please squash those together.
+
+#### Opening the pull request
+
+From within GitHub, opening a new pull request will present you with a template that should be filled out. Please try your best at filling out the details, but feel free to skip parts if you're not sure what to put.
+
+#### Discuss and update
+
+You will probably get feedback or requests for changes to your pull request.
+This is a big part of the submission process, so don't be discouraged! Some contributors may sign off on the pull request right away, others may have more detailed comments or feedback.
+This is a necessary part of the process in order to evaluate whether the changes are correct and necessary.
+
+**Any community member can review a PR, so you might get conflicting feedback**.
+Keep an eye out for comments from code owners to provide guidance on conflicting feedback.
+
+#### Reviewing pull requests
+
+**Any Foundry community member is welcome to review any pull request**.
+
+All contributors who choose to review and provide feedback on pull requests have a responsibility to both the project and individual making the contribution. Reviews and feedback must be helpful, insightful, and geared towards improving the contribution as opposed to simply blocking it. If there are reasons why you feel the PR should not be merged, explain what those are. Do not expect to be able to block a PR from advancing simply because you say "no" without giving an explanation. Be open to having your mind changed. Be open to working _with_ the contributor to make the pull request better.
+
+Reviews that are dismissive or disrespectful of the contributor or any other reviewers are strictly counter to the Code of Conduct.
+
+When reviewing a pull request, the primary goals are for the codebase to improve and for the person submitting the request to succeed. **Even if a pull request is not merged, the submitter should come away from the experience feeling like their effort was appreciated**. Every PR from a new contributor is an opportunity to grow the community.
+
+##### Review a bit at a time
+
+Do not overwhelm new contributors.
+
+It is tempting to micro-optimize and make everything about relative performance, perfect grammar, or exact style matches. Do not succumb to that temptation.
+
+Focus first on the most significant aspects of the change:
+
+1. Does this change make sense for Foundry?
+2. Does this change make Foundry better, even if only incrementally?
+3. Are there clear bugs or larger scale issues that need attending?
+4. Are the commit messages readable and correct? If it contains a breaking change, is it clear enough?
+
+Note that only **incremental** improvement is needed to land a PR. This means that the PR does not need to be perfect, only better than the status quo. Follow-up PRs may be opened to continue iterating.
+
+When changes are necessary, _request_ them, do not _demand_ them, and **do not assume that the submitter already knows how to add a test or run a benchmark**.
+
+Specific performance optimization techniques, coding styles and conventions change over time. The first impression you give to a new contributor never does.
+
+Nits (requests for small changes that are not essential) are fine, but try to avoid stalling the pull request. Most nits can typically be fixed by the Foundry maintainers merging the pull request, but they can also be an opportunity for the contributor to learn a bit more about the project.
+
+It is always good to clearly indicate nits when you comment, e.g.: `Nit: change foo() to bar(). But this is not blocking`.
+
+If your comments were addressed but were not folded after new commits, or if they proved to be mistaken, please, [hide them][hiding-a-comment] with the appropriate reason to keep the conversation flow concise and relevant.
+
+##### Be aware of the person behind the code
+
+Be aware that _how_ you communicate requests and reviews in your feedback can have a significant impact on the success of the pull request. Yes, we may merge a particular change that makes Foundry better, but the individual might just not want to have anything to do with Foundry ever again. The goal is not just having good code.
+
+##### Abandoned or stale pull requests
+
+If a pull request appears to be abandoned or stalled, it is polite to first check with the contributor to see if they intend to continue the work before checking if they would mind if you took it over (especially if it just has nits left). When doing so, it is courteous to give the original contributor credit for the work they started, either by preserving their name and e-mail address in the commit log, or by using the `Author: ` or `Co-authored-by: ` metadata tag in the commits.

+
+### Releasing
+
+Releases are automatically done by the release workflow when a tag is pushed, however, these steps still need to be taken:
+
+1. Ensure that the versions in the relevant `Cargo.toml` files are up-to-date.
+2. Update documentation links
+3. Perform a final audit for breaking changes.

+# Forge Standard Library • [![CI status](https://github.com/foundry-rs/forge-std/actions/workflows/ci.yml/badge.svg)](https://github.com/foundry-rs/forge-std/actions/workflows/ci.yml)
+
+Forge Standard Library is a collection of helpful contracts and libraries for use with [Forge and Foundry](https://github.com/foundry-rs/foundry). It leverages Forge's cheatcodes to make writing tests easier and faster, while improving the UX of cheatcodes.
+
+**Learn how to use Forge-Std with the [📖 Foundry Book (Forge-Std Guide)](https://getfoundry.sh/reference/forge-std/overview/).**
+
+## Install
+
+```bash
+forge install foundry-rs/forge-std
+```
+
+## Contracts
+
+### stdError
+
+This is a helper contract for errors and reverts. In Forge, this contract is particularly helpful for the `expectRevert` cheatcode, as it provides all compiler built-in errors.
+
+See the contract itself for all error codes.
+
+#### Example usage
+
+```solidity
+
+import "forge-std/Test.sol";
+
+contract TestContract is Test {
+    ErrorsTest test;
+
+    function setUp() public {
+        test = new ErrorsTest();
+    }
+
+    function testExpectArithmetic() public {
+        vm.expectRevert(stdError.arithmeticError);
+        test.arithmeticError(10);
+    }
+}
+
+contract ErrorsTest {
+    function arithmeticError(uint256 a) public {
+        a = a - 100;
+    }
+}
+```
+
+### stdStorage
+
+This is a rather large contract due to all of the overloading to make the UX decent. Primarily, it is a wrapper around the `record` and `accesses` cheatcodes. It can _always_ find and write the storage slot(s) associated with a particular variable without knowing the storage layout. By default, writing to packed storage variables is not supported and will throw an error. However, you can enable packed slot support by calling `enable_packed_slots()` before using `find()` or `checked_write()`.
+
+This works by recording all `SLOAD`s and `SSTORE`s during a function call. If there is a single slot read or written to, it immediately returns the slot. Otherwise, behind the scenes, we iterate through and check each one (assuming the user passed in a `depth` parameter). If the variable is a struct, you can pass in a `depth` parameter which is basically the field depth.
+
+I.e.:
+
+```solidity
+struct T {
+    // depth 0
+    uint256 a;
+    // depth 1
+    uint256 b;
+}
+```
+
+#### Example usage
+
+```solidity
+import "forge-std/Test.sol";
+
+contract TestContract is Test {
+    using stdStorage for StdStorage;
+
+    Storage test;
+
+    function setUp() public {
+        test = new Storage();
+    }
+
+    function testFindExists() public {
+        // Let's say we want to find the slot for the public
+        // variable `exists`. We just pass in the function selector
+        // to the `find` command
+        uint256 slot = stdstore.target(address(test)).sig("exists()").find();
+        assertEq(slot, 0);
+    }
+
+    function testWriteExists() public {
+        // Let's say we want to write to the slot for the public
+        // variable `exists`. We just pass in the function selector
+        // to the `checked_write` command
+        stdstore.target(address(test)).sig("exists()").checked_write(100);
+        assertEq(test.exists(), 100);
+    }
+
+    // It supports arbitrary storage layouts, like assembly-based storage locations
+    function testFindHidden() public {
+        // `hidden` is a random hash of bytes; iterating through slots would
+        // not find it. Our mechanism does
+        // Also, you can use the selector instead of a string
+        uint256 slot = stdstore.target(address(test)).sig(test.hidden.selector).find();
+        assertEq(slot, uint256(keccak256("my.random.var")));
+    }
+
+    // If targeting a mapping, you have to pass in the keys necessary to perform the find
+    // i.e.:
+    function testFindMapping() public {
+        uint256 slot = stdstore
+            .target(address(test))
+            .sig(test.map_addr.selector)
+            .with_key(address(this))
+            .find();
+        // in the `Storage` constructor, we wrote that this address' value was 1 in the map
+        // so when we load the slot, we expect it to be 1
+        assertEq(uint(vm.load(address(test), bytes32(slot))), 1);
+    }
+
+    // If the target is a struct, you can specify the field depth:
+    function testFindStruct() public {
+        // NOTE: see the depth parameter - 0 means 0th field, 1 means 1st field, etc.
+        uint256 slot_for_a_field = stdstore
+            .target(address(test))
+            .sig(test.basicStruct.selector)
+            .depth(0)
+            .find();
+
+        uint256 slot_for_b_field = stdstore
+            .target(address(test))
+            .sig(test.basicStruct.selector)
+            .depth(1)
+            .find();
+
+        assertEq(uint(vm.load(address(test), bytes32(slot_for_a_field))), 1);
+        assertEq(uint(vm.load(address(test), bytes32(slot_for_b_field))), 2);
+    }
+}
+
+// A complex storage contract
+contract Storage {
+    struct UnpackedStruct {
+        uint256 a;
+        uint256 b;
+    }

+    });
+
+    function hidden() public view returns (bytes32 t) {
+        // an extremely hidden storage slot
+        bytes32 slot = keccak256("my.random.var");
+        assembly {
+            t := sload(slot)
+        }
+    }
+}
+```
+
+### stdCheats
+
+This is a wrapper around miscellaneous cheatcodes that need wrappers to be more dev-friendly. It includes functions for pranking, dealing with ETH and tokens, deploying contracts, creating test addresses, time manipulation, and fuzzing helpers. In general, users may expect ETH to be put into an address with `prank`, but this is not the case for safety reasons. Explicitly, this `hoax` function should only be used for addresses that have expected balances as it will get overwritten. If an address already has ETH, you should just use `prank`. If you want to change that balance explicitly, just use `deal`. If you want to do both, `hoax` is also right for you.
+
+#### Example usage:
+
+```solidity
+
+// SPDX-License-Identifier: MIT OR Apache-2.0
+pragma solidity ^0.8.0;
+
+import "forge-std/Test.sol";
+
+// Inherit the stdCheats
+contract StdCheatsTest is Test {
+    Bar test;
+    function setUp() public {
+        test = new Bar();
+    }
+
+    function testHoax() public {
+        // we call `hoax`, which gives the target address
+        // eth and then calls `prank`
+        hoax(address(1337));
+        test.bar{value: 100}(address(1337));
+
+        // overloaded to allow you to specify how much eth to
+        // initialize the address with
+        hoax(address(1337), 1);
+        test.bar{value: 1}(address(1337));
+    }
+
+    function testStartHoax() public {
+        // we call `startHoax`, which gives the target address
+        // eth and then calls `startPrank`
+        //
+        // it is also overloaded so that you can specify an eth amount
+        startHoax(address(1337));
+        test.bar{value: 100}(address(1337));
+        test.bar{value: 100}(address(1337));
+        vm.stopPrank();
+        test.bar(address(this));
+    }
+}
+
+contract Bar {
+    function bar(address expectedSender) public payable {
+        require(msg.sender == expectedSender, "!prank");
+    }
+}
+```
+
+### Std Assertions
+
+Provides comprehensive assertion functions for testing, including equality checks (assertEq, assertNotEq), comparisons (assertLt, assertGt, assertLe, assertGe), approximate equality (assertApproxEqAbs, assertApproxEqRel), and boolean assertions (assertTrue, assertFalse). All assertions support multiple data types and optional custom error messages.
+
+### StdConfig
+
+This is a contract that parses a TOML configuration file and loads its variables into storage, automatically casting them on deployment. It assumes a TOML structure where top-level keys represent chain IDs or aliases. Under each chain key, variables are organized by type in separate sub-tables like `[<chain>.<type>]`, where type must be: `bool`, `address`, `bytes32`, `uint`, `int`, `string`, or `bytes`.

+```
+
+See the contract itself for supported TOML format and all available methods.
+
+### `console.log`
+
+Usage follows the same format as [Hardhat](https://hardhat.org/hardhat-network/reference/#console-log).
+It's recommended to use `console2.sol` as shown below, as this will show the decoded logs in Forge traces.
+
+```solidity
+// import it indirectly via Test.sol
+import "forge-std/Test.sol";
+// or directly import it
+import "forge-std/console2.sol";
+...
+console2.log(someValue);
+```
+
+If you need compatibility with Hardhat, you must use the standard `console.sol` instead.
+Due to a bug in `console.sol`, logs that use `uint256` or `int256` types will not be properly decoded in Forge traces.
+
+```solidity
+// import it indirectly via Test.sol
+import "forge-std/Test.sol";
+// or directly import it
+import "forge-std/console.sol";
+...
+console.log(someValue);
+```

+/**
+ * StdChains provides information about EVM compatible chains that can be used in scripts/tests.
+ * For each chain, the chain's name, chain ID, and a default RPC URL are provided. Chains are
+ * identified by their alias, which is the same as the alias in the `[rpc_endpoints]` section of
+ * the `foundry.toml` file. For best UX, ensure the alias in the `foundry.toml` file matches the
+ * alias used in this contract, which can be found as the first argument to the
+ * `setChainWithDefaultRpcUrl` call in the `initializeStdChains` function.
+ *
+ * There are two main ways to use this contract:
+ *   1. Set a chain with `setChain(string memory chainAlias, ChainData memory chain)` or
+ *      `setChain(string memory chainAlias, Chain memory chain)`
+ *   2. Get a chain with `getChain(string memory chainAlias)` or `getChain(uint256 chainId)`.
+ *
+ * The first time either of those are used, chains are initialized with the default set of RPC URLs.
+ * This is done in `initializeStdChains`, which uses `setChainWithDefaultRpcUrl`. Defaults are recorded in
+ * `defaultRpcUrls`.
+ *
+ * The `setChain` function is straightforward, and it simply saves off the given chain data.
+ *
+ * The `getChain` methods use `getChainWithUpdatedRpcUrl` to return a chain. For example, let's say
+ * we want to retrieve the RPC URL for `mainnet`:
+ *   - If you have specified data with `setChain`, it will return that.
+ *   - If you have configured a mainnet RPC URL in `foundry.toml`, it will return the URL, provided it
+ *     is valid (e.g. a URL is specified, or an environment variable is given and exists).
+ *   - If neither of the above conditions is met, the default data is returned.
+ *
+ * Summarizing the above, the prioritization hierarchy is `setChain` -> `foundry.toml` -> environment variable -> defaults.

+/// A captured trace of [`tracing`] spans that have `target = "r1cs"`.
+///
+/// This type can be thought of as a relative of
+/// [`std::backtrace::Backtrace`][`Backtrace`].
+/// However, rather than capturing the current call stack when it is
+/// constructed, a `ConstraintTrace` instead captures the current [span] and its
+/// [parents]. It allows inspection of the constraints that are left unsatisfied
+/// by a particular witness assignment to an R1CS instance.
+///
+/// # Formatting
+///
+/// The `ConstraintTrace` type implements `fmt::Display`, formatting the span
+/// trace similarly to how Rust formats panics. For example:
+///
+/// ```text
+///    0: r1cs-std::bits::something
+///           at r1cs-std/src/bits/test.rs:42
+///    1: r1cs-std::bits::another_thing
+///           at r1cs-std/src/bits/test.rs:15
+/// ```

+# ethers-providers
+
+Clients for interacting with Ethereum nodes.
+
+This crate provides asynchronous
+[Ethereum JSON-RPC](https://github.com/ethereum/wiki/wiki/JSON-RPC) compliant
+clients.
+
+For more information, please refer to the [book](https://gakonst.com/ethers-rs).
+
+> **Warning**
+>
+> This library is in the process of being deprecated. See [#2667](https://github.com/gakonst/ethers-rs/issues/2667) for more information.
+
+## Websockets
+
+This crate supports for WebSockets via `tokio-tungstenite`.
+Please ensure that you have the `ws` feature enabled if you wish to use WebSockets:
+
+```toml
+[dependencies]
+ethers-providers = { version = "2.0", features = ["ws"] }
+```
+
+## Interprocess Communication (IPC)
+
+This crate supports for Interprocess Communication via Unix sockets and Windows named pipes.
+Please ensure that you have the `ipc` feature enabled if you wish to use IPC:
+
+```toml
+[dependencies]
+ethers-providers = { version = "2.0", features = ["ipc"] }
+```
+
+## Ethereum Name Service
+
+The provider may also be used to resolve [Ethereum Name Service](https://ens.domains) (ENS) names
+to addresses (and vice versa).
+The default ENS address is [`0x00000000000C2E074eC69A0dFb2997BA6C7d2e1e`][ens]
+and can be overriden with the [`ens`](./struct.Provider.html#method.ens) method on the provider.
+
+[ens]: https://etherscan.io/address/0x00000000000C2E074eC69A0dFb2997BA6C7d2e1e
+
+## Examples
+
+```rust,no_run
+# use ethers_core::types::Address;
+# use ethers_providers::{Provider, Http, Middleware, Ws};
+# async fn foo() -> Result<(), Box<dyn std::error::Error>> {
+let provider = Provider::<Http>::try_from("https://eth.llamarpc.com")?;
+
+let block = provider.get_block(100u64).await?;
+println!("Got block: {}", serde_json::to_string(&block)?);
+
+let addr = "0x89d24a6b4ccb1b6faa2625fe562bdd9a23260359".parse::<Address>()?;
+let code = provider.get_code(addr, None).await?;
+println!("Got code: {}", serde_json::to_string(&code)?);
+# Ok(())
+# }
+```
+
+Using ENS:
+
+```rust,no_run
+# use ethers_providers::{Provider, Http, Middleware};
+# async fn foo() -> Result<(), Box<dyn std::error::Error>> {
+let provider = Provider::<Http>::try_from("https://eth.llamarpc.com")?;
+
+// Resolve ENS name to Address
+let name = "vitalik.eth";
+let address = provider.resolve_name(name).await?;
+
+// Lookup ENS name given Address
+let resolved_name = provider.lookup_address(address).await?;
+assert_eq!(name, resolved_name);
+
+/// Lookup ENS field
+let url = "https://vitalik.ca".to_string();
+let resolved_url = provider.resolve_field(name, "url").await?;
+assert_eq!(url, resolved_url);
+
+/// Lookup and resolve ENS avatar
+let avatar = "https://ipfs.io/ipfs/QmSP4nq9fnN9dAiCj42ug9Wa79rqmQerZXZch82VqpiH7U/image.gif".to_string();
+let resolved_avatar = provider.resolve_avatar(name).await?;
+assert_eq!(avatar, resolved_avatar.to_string());
+# Ok(())
+# }
+```
