OrthoConfig describes settings as a Rust struct, then loads that +struct from defaults, a configuration file, environment variables, and +command-line arguments. + +This guide starts with a small working CLI and grows it one practical task at a +time. Stop as soon as the application has what it needs. + +## Install OrthoConfig + +OrthoConfig needs Serde to turn merged values into the application's +configuration type. Add `clap` when the application defines its own command or +subcommand parser: + + +```toml +[dependencies] +clap = { version = "4.5", features = ["derive"] } +ortho_config = "0.9.0" +serde = { version = "1.0", features = ["derive"] } +``` + +The default features support TOML and the JSON-backed merge machinery used by +the derive. Optional `json5`, `yaml`, and `metrics` features are covered later. + +## Build the first layered CLI + +Start with one struct. The `prefix` is used for environment variables and for +the default file-discovery names. A trailing underscore is conventional and +keeps names such as `ACME_PORT` easy to read. + + +```rust +use ortho_config::{OrthoConfig, OrthoResult}; +use serde::{Deserialize, Serialize}; + +#[derive(Debug, Deserialize, Serialize, OrthoConfig)] +#[ortho_config(prefix = "ACME_")] +struct Config { + #[ortho_config(default = String::from("127.0.0.1"))] + host: String, + + #[ortho_config(default = 8080, cli_short = 'p')] + port: u16, + + #[ortho_config(default = String::from("info"))] + log_level: String, +} + +fn main() -> OrthoResult<()> { + let config = Config::load()?; + println!( + "host={} port={} log_level={}", + config.host, config.port, config.log_level + ); + Ok(()) +} +``` + +That one definition provides three spellings for each field: + +| Rust field | Command line | Environment | TOML | +| ----------- | ---------------- | ---------------- | ----------- | +| `host` | `--host` | `ACME_HOST` | `host` | +| `port` | `--port` or `-p` | `ACME_PORT` | `port` | +| `log_level` | `--log-level` | `ACME_LOG_LEVEL` | `log_level` | + +_Table 1: Rust fields and their command-line, environment, and TOML names._ + +Values are merged from lowest to highest precedence: + +1. `#[ortho_config(default = ...)]` values; +2. configuration files; +3. environment variables; and +4. command-line arguments. + +This means a checked-in file can provide team defaults, an environment variable +can adapt them for a deployment, and a one-off CLI option can override both. + +## See the configuration surface + +Different sources suit different moments. Start with durable team settings in +`.acme.toml`: + + +```toml +host = "0.0.0.0" +port = 9000 +log_level = "debug" +``` + +At deployment time, an environment variable can change the host without +rewriting the file. For a one-off run, a CLI option can change the port again: + + +```console +$ ACME_HOST=api.internal cargo run -- --port 3000 +host=api.internal port=3000 log_level=debug +``` + +The result shows all three surfaces working together: `log_level` comes from +TOML, `ACME_HOST` supplies `host`, and `--port` wins for `port`. The command +uses POSIX shell syntax; in PowerShell, set `$env:ACME_HOST = "api.internal"` +before running the same Cargo command. + +TOML is available by default. Enable the `yaml` or `json5` crate feature when +those formats are a better fit for application users; the +[file-format section](#enable-another-file-format) covers the details. + +By default, discovery checks an explicit `--config-path`, the +`ACME_CONFIG_PATH` environment variable, project and home dotfiles, and the +platform configuration directory. Explicitly requested files are required: a +missing `--config-path` is an error rather than a silent fallback. + +TOML naturally handles lists and nested values. For example, an application +could add `workers: Vec` and `labels: BTreeMap` to its +configuration struct, then use: + + +```toml +[[workers]] +name = "queue-a" +concurrency = 4 + +[[workers]] +name = "queue-b" +concurrency = 2 + +[labels] +region = "eu-west" +tier = "worker" +``` + +For vectors, `merge_strategy = "append"` appends higher-precedence values; +`merge_strategy = "replace"` replaces the collection. Use +`merge_strategy = "keyed"` for keyed collection merging. Choose the policy +deliberately when operators may combine file, environment, and CLI values. + +Configuration files can also contain `extends` entries. Relative paths are +resolved from the file that declares them, and parent layers are merged before +the child. OrthoConfig reports a missing parent with its absolute path and the +referencing file so the failure is actionable. + +## Make discovery match the application + +Application names do not need to bend around OrthoConfig's defaults. Put the +discovery contract beside the struct when the public flag or filenames are part +of the CLI design: + + +```rust +use ortho_config::{OrthoConfig, OrthoResult}; +use serde::{Deserialize, Serialize}; + +#[derive(Debug, Deserialize, Serialize, OrthoConfig)] +#[ortho_config( + prefix = "ACME_", + discovery( + app_name = "acme-server", + config_file_name = "server.toml", + dotfile_name = ".acme-server.toml", + project_file_name = ".acme-server.toml", + config_cli_long = "config", + config_cli_short = 'c', + config_cli_visible = true + ) +)] +struct Config { + #[ortho_config(default = 8080)] + port: u16, +} + +fn main() -> OrthoResult<()> { + let config = Config::load()?; + println!("port={}", config.port); + Ok(()) +} +``` + +This application accepts `--config` and `-c`, reads `ACME_CONFIG_PATH`, looks +for `.acme-server.toml` in project locations, and uses `server.toml` in +platform configuration directories. Keeping these choices in the derive also +exposes them through `OrthoConfigDocs`. + +### Handle every `load_first` outcome + +`ConfigDiscovery::load_first` distinguishes three outcomes. `Ok(Some(...))` +contains the first successfully parsed candidate. `Ok(None)` means discovery +had no candidates to try. `Err(...)` means candidates existed but none loaded +successfully; surface or map that error rather than treating it as absence: + + +```rust +use ortho_config::{ConfigDiscovery, OrthoResult}; + +fn load_discovered_config(discovery: &ConfigDiscovery) -> OrthoResult<()> { + match discovery.load_first() { + Ok(Some(_config)) => { + // Merge or deserialize the discovered Figment value. + println!("discovery=loaded"); + Ok(()) + } + Ok(None) => { + // Continue with application defaults. + println!("discovery=absent"); + Ok(()) + } + Err(error) => Err(error), + } +} + +fn main() -> OrthoResult<()> { + let discovery = ConfigDiscovery::builder("acme").build(); + load_discovered_config(&discovery) +} +``` + +## Test discovery without changing the process environment + +Tests that mutate environment variables interfere with one another. Build a +`ConfigDiscovery` with `MapEnv` instead. Each test owns its values and can run +in parallel: + + +```rust +use ortho_config::{ConfigDiscovery, MapEnv}; +use std::sync::Arc; + +fn main() { + let environment = Arc::new( + MapEnv::new() + .with_var("ACME_CONFIG", "/srv/acme/server.toml") + .with_var("HOME", "/home/tester"), + ); + + let discovery = ConfigDiscovery::builder("acme") + .env_var("ACME_CONFIG") + .env_source(environment) + .clear_project_roots() + .build(); + + assert_eq!( + discovery.candidates().first().map(|path| path.as_path()), + Some(std::path::Path::new("/srv/acme/server.toml")) + ); + println!("candidate=/srv/acme/server.toml"); +} +``` + +`ProcessEnv` remains the default, so production applications do not need to +change. `EnvSource` deliberately supports lookup by name but not enumeration; +discovery cannot accidentally scan or log unrelated environment values. + +## Give each subcommand its own settings + +Many CLIs have global options plus commands with different configuration. Derive +`OrthoConfig` for each subcommand's argument struct and merge only the +selected command: + + +```rust +use clap::{Parser, Subcommand}; +use ortho_config::{OrthoConfig, OrthoResult, SubcmdConfigMerge}; +use serde::{Deserialize, Serialize}; + +#[derive(Debug, Parser)] +#[command(name = "acme")] +struct Cli { + #[command(subcommand)] + command: Command, +} + +#[derive(Debug, Subcommand)] +enum Command { + Serve(ServeConfig), +} + +#[derive(Debug, Default, Parser, Deserialize, Serialize, OrthoConfig)] +#[command(name = "serve")] +#[ortho_config(prefix = "ACME_SERVE_")] +struct ServeConfig { + #[arg(long)] + port: Option, +} + +fn main() -> OrthoResult<()> { + match Cli::parse().command { + Command::Serve(cli) => { + let config = cli.load_and_merge()?; + println!("port={:?}", config.port); + } + } + Ok(()) +} +``` + +For an enum with many variants, derive `SelectedSubcommandMerge` and use +`load_globals_and_merge_selected_subcommand`. The generated match keeps the +entry point small. Add `#[ortho_config(cli_default_as_absent)]` to a field when +a `clap` default should not override a value supplied by a file or environment +variable. + +## Handle errors at the application boundary + +Library APIs return `OrthoResult`, whose error is an `Arc`. +Propagate it while loading, then render or map it where the application owns +the user experience: + + +```rust +use ortho_config::{OrthoConfig, OrthoError}; +use serde::Deserialize; + +#[derive(Debug, Deserialize, OrthoConfig)] +struct Config { + port: u16, +} + +fn main() { + match Config::load_from_iter(["acme", "--port", "not-a-number"]) { + Ok(config) => println!("port={}", config.port), + Err(error) => match error.as_ref() { + OrthoError::CliParsing(clap_error) => eprintln!("{clap_error}"), + other => eprintln!("configuration error: {other}"), + }, + } +} +``` + +Preserve `clap`'s display-only exits for `--help` and `--version`; use +`is_display_request` when a wider application error layer needs to distinguish +them. `OrthoError::try_aggregate` combines independent validation failures +without inventing an error for an empty collection. The result extension traits +`OrthoResultExt`, `OrthoMergeExt`, and `ResultIntoFigment` keep conversions +explicit at integration boundaries. + +## Localize help and parse failures together + +Localization is most reliable when the command metadata is translated before +parsing and any resulting error goes through the same localizer. +`LocalizedParse` provides that path for the common case: + + +```rust +use clap::Parser; +use ortho_config::{LocalizedParse, NoOpLocalizer}; + +#[derive(Debug, Parser)] +#[command(name = "acme", bin_name = "acme")] +struct Cli { + #[arg(long)] + verbose: bool, +} + +fn main() -> Result<(), clap::Error> { + let localizer = NoOpLocalizer::new(); + let cli = Cli::try_parse_localized_from( + ["acme", "--verbose"], + &localizer, + )?; + assert!(cli.verbose); + println!("verbose={}", cli.verbose); + Ok(()) +} +``` + +Use `FluentLocalizer` for translated catalogues. Use `LocalizeCmd::with_base` +with `parse_localized_command` when catalogue identifiers must use an explicit +root rather than the binary name. Missing translations fall back to the original +`clap` text and emit a warning event, so users still receive a useful error. + +## Add production diagnostics + +OrthoConfig emits structured `tracing` events for discovery attempts, selected +files, skips, and failures. The library does not install a subscriber; the +binary should do that once during start-up. Add the subscriber with its +environment-filter support: + + +```toml +[dependencies] +tracing-subscriber = { version = "0.3", features = ["env-filter"] } +``` + + +```rust +use ortho_config::{OrthoConfig, OrthoResult}; +use serde::Deserialize; + +#[derive(Deserialize, OrthoConfig)] +struct Config { + #[ortho_config(default = 8080)] + port: u16, +} + +fn main() -> OrthoResult<()> { + tracing_subscriber::fmt() + .with_env_filter("ortho_config=debug") + .with_writer(std::io::stderr) + .try_init() + .ok(); + + let config = Config::load()?; + println!("port={}", config.port); + Ok(()) +} +``` + +Do not log configuration values or candidate paths around these events. The +crate's own diagnostics avoid path and value fields because configuration +locations and values may be sensitive. + +Metrics are a low-cost opt-in when the application already has a `metrics` +recorder: + + +```toml +[dependencies] +ortho_config = { version = "0.9.0", features = ["metrics"] } +``` + +The feature emits bounded counters such as discovery attempts, outcomes, and +failures. OrthoConfig never installs a recorder, and enabling the feature does +nothing visible until the application installs one. + +## Generate help from the same metadata + +`#[derive(OrthoConfig)]` also implements `OrthoConfigDocs`. The metadata +records fields, source names, precedence, discovery, defaults, and nested +subcommands. Derive `OrthoConfigSubcommandDocs` on a `clap::Subcommand` enum so +the generated tree includes every variant. + +Inspect the metadata in code: + + +```rust +use ortho_config::{OrthoConfig, OrthoConfigDocs}; +use serde::{Deserialize, Serialize}; + +#[derive(Deserialize, Serialize, OrthoConfig)] +#[ortho_config(prefix = "ACME_")] +struct Config { + /// Address on which the service listens. + #[ortho_config(default = String::from("127.0.0.1"))] + host: String, +} + +fn main() { + let metadata = Config::get_doc_metadata(); + assert_eq!(metadata.fields.len(), 1); + assert_eq!(metadata.fields[0].name, "host"); + println!("field={}", metadata.fields[0].name); +} +``` + +Or use `cargo-orthohelp` to emit intermediate representation (IR), Unix man +pages, PowerShell help, compact agent context, or all formats: + + +```console +cargo orthohelp --package hello_world --format agent-context +``` + +The tool builds a small bridge against the selected package. Keep the root +configuration type public and ensure its documentation metadata is available +from the selected library or binary target. `--format all` includes agent +context as well as IR, man pages, and PowerShell output. + +## Offer a compact contract to automation + +Agent context complements human help with a small, stable JSON description of +commands, inputs, output modes, interaction, and mutation boundaries. A common +application convention is `context --json`; `cargo-orthohelp` uses +`--format agent-context` for generation. + +The smallest valid context created by `AgentContext::new("acme")` serializes to +this shape: + + +```json +{ + "schema_version": "1", + "kind": "acme.agent_context", + "package": "acme", + "commands": [], + "profiles": { "supported": false }, + "feedback": { "supported": false }, + "policy": { "agent_native": "warn" }, + "skill_manifests": [] +} +``` + +Fill `AgentCommand` entries only with claims the executable honours. +`SkillManifest` and `SkillCommandRef` link skills to real commands. They do not +replace command validation or grant an agent capabilities that the CLI does not +have. + +## Use an aliased dependency + +Cargo permits dependency aliases. In v0.9.0 the derive macros can generate +paths through that alias, which is useful in workspaces that reserve the +canonical crate name: + + +```toml +[dependencies] +config_layer = { package = "ortho_config", version = "0.9.0" } +serde = { version = "1.0", features = ["derive"] } +``` + +Name the alias on every type that derives an OrthoConfig macro: + + +```rust +use config_layer::{OrthoConfig, OrthoResult}; +use serde::Deserialize; + +#[derive(Deserialize, OrthoConfig)] +#[ortho_config(crate = "config_layer", prefix = "ACME_")] +struct Config { + #[ortho_config(default = 8080)] + port: u16, +} + +fn main() -> OrthoResult<()> { + let config = Config::load_from_iter(["acme"])?; + assert_eq!(config.port, 8080); + println!("port={}", config.port); + Ok(()) +} +``` + +The same attribute is supported by `SelectedSubcommandMerge`. OrthoConfig +re-exports the dependencies used by generated code, so a derive-only consumer +does not need direct `figment`, `uncased`, `xdg`, or format-parser dependencies. + +## Enable another file format + +TOML is enabled by default. Enable `json5` or `yaml` when users already work in +that format. YAML uses YAML 1.2 semantics in v0.9.0: legacy words such as `yes` +and `on` remain strings, and duplicate mapping keys are rejected. + + +```yaml +enabled: yes +mode: on +port: 8080 +``` + +Enable YAML with `features = ["yaml"]`; this also requires the `serde_json` +feature, which is part of the default feature set. If defaults are disabled, +enable both explicitly. Treat a change from v0.8.0 YAML parsing as a data +migration and run representative production files through v0.9.0 before +deploying. + +## A practical path from here + +For a new CLI, begin with the first layered struct and add only the required +sections. A typical progression is: + +1. choose stable CLI and environment names; +2. add a project file for durable settings; +3. customize discovery if the defaults are not part of the public interface; +4. split independent commands into subcommand configurations; +5. localize help and initialize tracing at the application boundary; and +6. generate human and agent documentation once the command surface stabilizes. + +The [Hello World application](../examples/hello_world/) demonstrates these +pieces in a larger layout. The +[v0.9.0 migration guide](v0-9-0-migration-guide.md) explains compatibility +changes for existing v0.8.0 users, and the +[API documentation](https://docs.rs/ortho_config) is the source for complete +type and method signatures. From e91815858611c1e514eaf231f8c53ee43a23ff6e Mon Sep 17 00:00:00 2001 From: leynos Date: Fri, 21 Aug 2026 17:55:25 +0200 Subject: [PATCH 02/13] Add execplan for root whitaker binary (3.5.1) Draft the execution plan for roadmap item 3.5.1: add a real `whitaker` binary at the root package and move the current installer orchestration behind an internal library boundary. The plan places the CLI domain, ports, and adapters in a new `crates/whitaker_cli` crate rather than in the root package, because the root package's library requires `feature(rustc_private)` and is excluded from `make test` by `TEST_EXCLUDES`. The root `src/main.rs` becomes a thin composition root. Scope is limited to `install` and `ls`; `check` and `doctor`, the configuration model, and the deprecation shim remain with their own roadmap items.

The sections +`Constraints`, `Tolerances`, `Risks`, `Progress`, `Surprises & discoveries`, +`Decision log`, `Outcomes & retrospective`, `Conformance basis`, and +`Verification plan` must be kept up to date as work proceeds. + +Status: DRAFT + +## Purpose / big picture + +Today a user who wants Whitaker installs and runs a binary called +`whitaker-installer`, and reaches the lint inventory through a generated +wrapper script called `whitaker-ls`. The product is named Whitaker but there +is no program called `whitaker`. + +After this change there is. A user runs: + +```console +whitaker --help +whitaker install +whitaker ls +whitaker ls --json +``` + +and gets exactly the behaviour `whitaker-installer` and `whitaker-installer +list` give today, from a real Rust binary named `whitaker`, installable with +`cargo install whitaker` or `cargo binstall whitaker`. + +That is the entire user-visible outcome. It is deliberately narrow. The +commands `whitaker check` and `whitaker doctor` described in the CLI design +document are **not** part of this plan; they are separate roadmap items that +depend on this one. This plan builds the foundation they land on: a real +root binary, and an internal library boundary that separates decision-making +policy from the input/output work that carries it out. + +The second half of the outcome is invisible to users but is the reason the +work is worth doing. The installer's orchestration logic currently lives +inside a binary target (`installer/src/main.rs`, plus two binary-private +modules) where no other program can reach it and no integration test can call +it directly. This plan moves that orchestration into a library crate with +explicit ports, so that the four subcommands still to come can be built by +composing that library rather than by copying the binary. + +## Definitions + +Terms used throughout, defined here so no prior knowledge is assumed. + +**Dylint.** A tool that runs custom Rust lints compiled as dynamic libraries. +Whitaker's lints are Dylint lints. `cargo-dylint` and `dylint-link` are the +two helper binaries Dylint needs. + +**Lint bundle / staged library.** A compiled Dylint lint library copied into a +known directory with a filename encoding the toolchain it was built for. +"Staging" is the act of copying it there. + +**Prebuilt artefact.** A `.tar.zst` archive of already-compiled lint libraries +published on GitHub Releases, so users do not have to compile lints locally. + +**`cargo-binstall`.** A tool that installs a Rust binary by downloading a +prebuilt release archive instead of compiling. It reads a +`[package.metadata.binstall]` table from `Cargo.toml` to learn the archive URL +pattern. + +**Port (hexagonal architecture).** A Rust trait, owned by the domain layer, +describing something the domain needs from the outside world (for example +"install the Dylint tools") without saying how it is done. + +**Adapter.** A concrete implementation of a port that does the real work, for +example by spawning a process or writing a file. + +**Composition root.** The single place — here, `src/main.rs` — where concrete +adapters are constructed and handed to the domain. Nothing else in the program +chooses implementations. + +**Driving vs driven.** A _driving_ adapter calls into the domain (the CLI +parser). A _driven_ adapter is called by the domain (the installer). + +**ExecPlan plateau.** A milestone that leaves the repository correct, +coherent, and safe to stop at. + +## Context and orientation + +You have only this repository and this document. Here is what exists. + +### The workspace + +The Cargo workspace root is the repository root. `Cargo.toml` line 2 declares +members `["common", "crates/*", "installer", "suite"]`. The root directory is +itself a package: + +```toml +[package] +name = "whitaker" +version = "0.2.7" +edition = "2024" +``` + +That root package **has no binary today**. It has only a library, +`src/lib.rs`, which is the shared support library for Whitaker's Dylint lint +crates. Its first two lines matter a great deal to this plan: + +```rust +//! Core Whitaker library surfaces shared configuration and helpers for lint crates. +#![cfg_attr(feature = "dylint-driver", feature(rustc_private))] +``` + +Under the `dylint-driver` feature this library links `rustc_driver` and the +private compiler crates. A comment in that file records the consequence: + +```rust +// Unit tests of this crate should not pull the compiler driver to avoid the +// duplicated `std`/`core` link errors seen during all-features test runs. +``` + +This is why `Makefile` line 24 excludes the root package from the test run: +`TEST_EXCLUDES` contains `--exclude whitaker`. Read that line before starting +work; it is the single most important constraint on where new code may live. + +### The installer + +`installer/` is the package `whitaker-installer`. It already has a library +(`installer/src/lib.rs`, 84 lines) exposing about 25 public modules, and four +binaries declared with `autobins = false` in `installer/Cargo.toml` lines +11-27. The one users install is `whitaker-installer`, built from +`installer/src/main.rs`. The other three (`whitaker-package-lints`, +`whitaker-package-installer`, `whitaker-package-dependency-binary`) are +release-packaging utilities and are out of scope here. + +`installer/src/main.rs` is 402 lines. It parses `whitaker_installer::cli::Cli` +with clap and dispatches: + +```rust +fn run(cli: &Cli, stdout: &mut dyn Write, stderr: &mut dyn Write) -> Result<()> { + match &cli.command { + Some(Command::List(args)) => run_list(args, stdout), + Some(Command::Install(args)) => run_install(args, stderr), + None => run_install(cli.install_args(), stderr), + } +} +``` + +The important fact is what else is in that file and in two modules declared +only by it (`mod install_flow;` and `mod staged_suite;`, lines 7-8). These are +**binary-private**: they are not part of the `whitaker_installer` library and +no other crate can call them. They contain real orchestration: + +- `run_install`, `run_dry`, `try_fast_path_installation`, `finish_install`, + `finish_install_and_record_metrics`, `resolve_requested_crates`, + `generate_and_report_wrapper`, `ensure_whitaker_workspace`, + `resolve_toolchain`, `ensure_toolchain_installed`, `exit_code_for_run_result` + (all in `installer/src/main.rs`); +- `install_flow::try_prebuilt_installation`, `install_flow::detect_host_target` + and the `PrebuiltInstallationHooks` struct + (`installer/src/install_flow/mod.rs`); +- `staged_suite::try_test_staged_suite_installation` + (`installer/src/staged_suite.rs`, a debug-only test hook). + +Moving those behind a library boundary is the "internal library boundary" half +of this task. + +### Existing seams + +The installer is not a monolith. It already has dependency-injection seams, +but they are inconsistent — three different styles for the same concern: + +| Trait / seam | Defined at | Style | +| --- | --- | --- | +| `deps::CommandExecutor` | `installer/src/deps/mod.rs:36` | public trait object | +| `toolchain::CommandRunner` | `installer/src/toolchain/mod.rs:44` | **private** trait object, same shape | +| `dirs::BaseDirs` | `installer/src/dirs.rs:41` | public trait object, `mockall` | +| `builder::CrateBuilder` | `installer/src/builder.rs:58` | public trait object, `mockall` | +| `artefact::download::ArtefactDownloader` | `installer/src/artefact/download.rs:29` | public trait object, `mockall` | +| `install_flow::PrebuiltInstallationHooks` | `installer/src/install_flow/mod.rs:135` | **bare `fn` pointers** | + +_Table 1: Existing dependency-injection seams in the installer._ + +And three places spawn processes with no seam at all: +`installer/src/git.rs` (`Command::new("git")`), +`installer/src/builder.rs:83` (`Command::new("cargo")` inside +`Builder::build_crate`), and `install_flow::detect_host_target` +(`Command::new("rustc")`). + +This plan does **not** unify all of those. Doing so would be a large, +independently valuable refactor with its own risk profile. This plan defines +the ports the new CLI needs and implements them over the installer library as +it stands, leaving the installer's internal seam inconsistency for a later +item. That choice is recorded in `Decision log`. + +### Where tests live + +- Unit tests: colocated, either `#[cfg(test)] mod tests` inline or a sibling + `_tests.rs` file declared with `#[cfg(test)] mod foo_tests;`. +- Behavioural tests: `/tests/behaviour_*.rs` integration binaries, + paired with Gherkin files in `/tests/features/*.feature`, bound with + `#[scenario(path = "...", index = N)]`. **The bindings are index-based; + reordering scenarios in a feature file silently rebinds them.** See the + warning comment at `installer/tests/behaviour_cli/scenarios.rs:7`. +- Shared behavioural state uses a "World" struct fixture, for example + `CliWorld` in `installer/tests/behaviour_cli/support.rs`. +- End-to-end CLI tests spawn the binary via the Cargo-provided + `env!("CARGO_BIN_EXE_")`. There is no `assert_cmd` in this + workspace. +- Snapshots live in a `snapshots/` directory beside the test that writes them, + with `insta`'s default `____.snap` naming.

Violation requires escalation, not a workaround. + +1. **`whitaker-installer` keeps working unchanged.** Its command-line surface, + exit codes, and output must be byte-identical before and after. It is a + released binary documented in `docs/users-guide.md`, published to GitHub + Releases, installed by `make install-smoke`, and exercised by + `installer/tests/behaviour_cli.rs`. `CLI-DESIGN` schedules its deprecation + for a later release (`CLI-REQ-SHIM`, roadmap 3.9.1), not this one. This is + not a compatibility shim invented to make a milestone viable: it is the + currently shipping product, and this plan adds a second entry point beside + it rather than replacing it. +2. **The public library surface of `whitaker_installer` must not shrink.** The + integration tests under `installer/tests/` compile against it as an + external crate and can only see `pub` items. `installer/Cargo.toml` lines + 29-55 gate `StubExecutor` and `InstallerError::StubMismatch` behind the + `test-support` feature, which roadmap item 3.2.2 declares a supported + surface for external test suites. Items may be added; existing ones may not + be removed or narrowed. +3. **The root package must remain named `whitaker` at version `0.2.7`**, and + the new binary must be named `whitaker`, so that `cargo install whitaker` + and `cargo binstall whitaker` resolve correctly. +4. **No new lint suppressions.** `Cargo.toml` `[workspace.lints]` sets + `unsafe_code = "forbid"`, `missing_docs = "deny"`, `allow_attributes = + "deny"` and clippy `pedantic` at warn with `-D warnings`. Adding + `#[allow(...)]` to get past a gate is a tolerance breach. +5. **No file may exceed 400 lines** (`AGENTS.md`). Every module needs a `//!` + doc comment. +6. **Direct environment mutation in tests is forbidden** (`AGENTS.md`). Use + `temp-env`, or dependency injection through a port. +7. **The prebuilt-artefact download path must not change behaviour.** It is + governed by `docs/adr-001-prebuilt-dylint-libraries.md` and by the release + workflow's published asset names. +8. **Caret dependency requirements only** (`AGENTS.md`); no `*` or `>=`. + +## Tolerances (exception triggers) + +Stop and escalate — do not improvise — when any of these is reached. + +- **Scope.** More than 45 files changed, or more than 2,500 net added lines + across the whole plan. The estimate is roughly 30 files and 1,800 lines. +- **Root-binary feasibility.** If `EP-M0` shows a binary in the root package + cannot build under `--all-features`, stop at the end of `EP-M0` and + escalate with the options in `Risk R1`. Do not silently relocate the binary + to a differently-named package: that would break `cargo install whitaker` + and violate Constraint 3. +- **Interface.** If discharging `CLI-REQ-LIB` requires removing or narrowing + any existing `pub` item in `whitaker_installer`, stop (Constraint 2). +- **Dependencies.** Four new dependencies are pre-authorized and listed in + `Interfaces and dependencies`: `ortho_config`, `googletest`, + `pretty_assertions`, and `insta` promoted to a root dev-dependency. Any + fifth new external dependency triggers escalation. +- **Iterations.** If a gate still fails after three fix attempts on the same + root cause, stop and escalate with the captured log path. +- **Verification.** If a Kani harness exceeds 15 minutes, or a Verus proof + exceeds 5 minutes, stop and escalate rather than raising the bound or the + timeout. +- **Behaviour drift.** If any existing `installer/tests/` test needs its + assertions changed (as opposed to being moved or added to), stop: that is + evidence of a Constraint 1 violation. +- **Ambiguity.** If `CLI-DESIGN` and `docs/roadmap.md` disagree on whether a + behaviour belongs to 3.5.1, stop and present both readings. + +## Risks + +**R1 — A binary in the root package may not build under `--all-features`.** +Severity: high. Likelihood: medium-high. +The root library sets `feature(rustc_private)` and links `rustc_driver` when +`dylint-driver` is enabled. `make typecheck`, `make lint`, and `make test` all +pass `--all-features`, which enables it. `src/lib.rs` records that all-features +test runs produce "duplicated `std`/`core` link errors", and `Makefile` line 24 +excludes the package from the test run for that reason. A binary target in the +same package may inherit the same failure. +Mitigation: `EP-M0` is a timeboxed prototyping milestone that answers this +empirically before any design is committed. If it fails, the recommended +remedy is to extract the Dylint driver library out of the root package into +`crates/whitaker_lint_core`, leaving the root package as the CLI package — +which permanently removes the conflict — but that is a scope increase +requiring approval, not an autonomous decision. + +**R2 — Index-based BDD scenario bindings break silently.** +Severity: medium. Likelihood: medium. +`#[scenario(path = "...", index = N)]` binds by position. Inserting a scenario +in the middle of an existing `.feature` file rebinds every later scenario to +the wrong step definitions, and the suite may still pass. +Mitigation: put all new scenarios in **new** feature files +(`crates/whitaker_cli/tests/features/*.feature`); never insert into +`installer/tests/features/installer.feature`. `EP-M2` acceptance includes +re-running `installer/tests/behaviour_cli.rs` unchanged. + +**R3 — Two packages publishing artefacts with one URL template may collide.** +Severity: high. Likelihood: low-medium. +`installer/Cargo.toml` lines 95-101 template the release URL as +`{name}-{target}-v{version}.{archive-format}`. Giving the `whitaker` package +the same pattern means two packages generate asset names from the same +template. Because `whitaker` is a proper prefix of `whitaker-installer`, and +target triples themselves contain `-`, an ambiguous split is conceivable. +Mitigation: `EP-LEM-NAME`, a Verus proof that the composed name determines its +fields uniquely, plus a `proptest` differential check. See `Verification +plan`. + +**R4 — `--help` and `--version` may exit non-zero.** +Severity: medium. Likelihood: medium. +clap reports `--help` as an `Err` variant. Routing every `Err` to exit code 1 +would make `whitaker --help` fail. `ortho_config::is_display_request` exists +precisely to distinguish this case, and it is easy to omit. +Mitigation: `EP-INV-EXIT` covers it with both a parameterized test and an +end-to-end assertion on the real process exit status. + +**R5 — Promoting binary-private modules widens the public API.** +Severity: medium. Likelihood: medium. +`install_flow` and `staged_suite` are binary-private today. Making them +reachable from a new crate could expose test-only machinery — `staged_suite` +in particular is a debug-only hook driven by the +`WHITAKER_INSTALLER_TEST_STAGE_SUITE` environment variable. +Mitigation: promote to `pub` only what the new ports need; keep +`staged_suite`'s hook behind the existing `#[cfg(debug_assertions)]` and +`test_support` gating; record the resulting surface in the `EP-M4` ADR. + +**R6 — `ortho_config` pulls a large dependency subtree.** +Severity: low. Likelihood: high (it is certain; the question is whether it +matters). `ortho_config` 0.9.0 depends on `figment`, `fluent-bundle`, +`fluent-syntax`, `unic-langid`, `clap-dispatch`, `directories`, `xdg`, and +more. +Mitigation: adopt it in this plan for localized parsing only, so the cost is +paid once at the point the roadmap already commits to it (item 3.6.3), not +twice. Confirm `make typecheck` build time does not regress by more than 30%; +report if it does. + +**R7 — Snapshot tests of `--help` are brittle across clap versions.** +Severity: low. Likelihood: medium. +`insta` snapshots of help text change whenever clap adjusts its formatting. +Mitigation: snapshot the _structure_ — the subcommand list and the option +names — rather than full rendered help; assert full text only for the +stable `ls --json` output, which is a machine contract. + +## Verification plan + +This change is mostly a refactor plus a new entry point, so it would be easy +to claim it introduces no invariants. That is not true, and saying so would be +the vacuous option. Three genuine obligations arise, and one lemma. + +### Axioms (assumed, not verified here) + +- `clap` 4.5 parses an argument vector into the derived struct according to + its documented derive semantics. Third-party internals are not verified. +- `ortho_config` 0.9.0's `LocalizedParse::try_parse_localized_from` and + `is_display_request` behave as documented. Repository-owned logic built on + them **is** verified, against the real interface. +- `cargo-binstall` resolves `pkg-url` by substituting `{name}`, `{target}`, + `{version}`, and `{archive-format}` literally. +- The GitHub release workflow publishes assets under exactly the names + produced by `installer/src/artefact/naming.rs`. +- Kani sequentializes concurrency; no obligation below concerns concurrency. + +### EP-INV-PARITY — install-argument parity + +- **Obligation.** For every argument vector `v` that `whitaker-installer` + accepts as an install invocation, `whitaker install v` parses to an + `InstallRequest` equal to the one `whitaker-installer` produces from `v`; + and for every `v` that `whitaker-installer` rejects, `whitaker install v` is + rejected too. +- **Method.** Property test (`proptest`), differential. +- **Rationale.** This is the precise formal content of "move the current + installer behaviour behind a library boundary _without changing it_". The + flag surface has 14 options with two documented conflict pairs; enumerating + it by hand would miss combinations, and the space is far too large for + bounded model checking over strings. +- **Domain.** Generated argument vectors over the 14 flags declared in + `installer/src/cli.rs:77-181`, including repeated `--lint`, repeated `-v`, + the `--lint` / `--individual-lints` conflict, the `-v` / `-q` conflict, + paths containing spaces and non-ASCII characters, and empty values. +- **Artefact.** `crates/whitaker_cli/tests/property_arg_parity.rs`. +- **Evidence.** `cargo nextest run -p whitaker_cli property_arg_parity`. Red + stage: written before the mapping exists, so it fails to compile, then fails + on a deliberately incomplete mapping that drops `--jobs`. Discharged when it + passes with 1,024 generated cases and the regression file is committed. +- **Non-vacuity.** The generator must be _classified_: record via + `proptest::prop_assume!`-free construction and explicit + `Strategy::prop_map` that each of the 14 flags appears set in at least 5% of + cases, that both conflict pairs are generated, and that at least one case + has zero flags. A run where any flag is never exercised is a **failure**, + not a pass. Negative control: temporarily drop `--no-update` from the + `whitaker install` mapping; the test must fail naming that flag. Restore + afterwards and record the transcript. + +### EP-INV-ROUTE — routing totality and conflict rejection + +- **Obligation.** The function mapping a parsed CLI to a domain `Request` is + total (never panics, never returns a "cannot happen" error) over all + reachable flag combinations, and rejects exactly the two documented conflict + pairs. +- **Method.** Bounded model check (Kani), complemented by parameterized + `rstest` cases. +- **Rationale.** Totality over a combinatorial flag space is exactly what + bounded exhaustive exploration is for, and the space is small enough to + explore completely once flags are modelled as booleans rather than strings. + A property test would sample it; Kani covers it. +- **Domain.** The boolean flags modelled as a bitmask, plus a bounded + `Option` for `--jobs` and a bounded 0-3 count for `-v`. Ten booleans + gives 1,024 states; with the two bounded integers the harness explores under + 10^5 states, well inside Kani's practical range for non-heap types. + `#[kani::unwind(4)]` bounds the single loop over requested lints, capped at + three entries. +- **Artefact.** `crates/whitaker_cli/src/domain/routing/kani.rs`, gated + `#[cfg(kani)]`, registered in `scripts/run-kani.sh` alongside the existing + named harnesses. +- **Evidence.** `make kani 2>&1 | tee /tmp/kani-whitaker-3-5-1.out`. Expect + `VERIFICATION:- SUCCESSFUL` for + `verify_route_request_is_total_over_bounded_flags` and + `verify_route_request_rejects_documented_conflicts`. +- **Non-vacuity.** The harness must drive the **production** routing function, + not a re-implementation. Assumptions must not collapse the space: assert + before the main property that at least one satisfying assignment reaches + each of the three routing outcomes (install, list, conflict-rejected) by + running three separate `#[kani::proof]` reachability harnesses that assert + `false` under a constraint selecting that outcome, and confirming each + reports a counterexample — proving the branch is reachable. Negative + control: remove the `--lint` / `--individual-lints` conflict check from the + production function; `verify_route_request_rejects_documented_conflicts` + must fail with a concrete counterexample. Restore and record. + +### EP-INV-EXIT — exit-code policy + +- **Obligation.** The process exit code is `0` for success and for a clap + display request (`--help`, `--version`); `1` for an operational failure. No + input produces any other code, and no display request produces a non-zero + code. +- **Method.** Parameterized tests (`rstest` with `googletest` matchers) over + the finite partition of outcome kinds, plus an end-to-end assertion on the + real spawned process. +- **Rationale.** The outcome space is a small finite partition — the natural + fit for parameterized testing. The end-to-end case is what makes it + non-vacuous, because the unit-level mapping can be right while `main` + discards it. +- **Domain.** Every variant class of `InstallerError` grouped by kind, plus + `Ok(())`, plus clap `ErrorKind::DisplayHelp` and `DisplayVersion`, plus a + genuine parse error. +- **Artefact.** `crates/whitaker_cli/src/domain/exit_tests.rs` and + `crates/whitaker_cli/tests/e2e_exit_codes.rs`. +- **Evidence.** `cargo nextest run -p whitaker_cli exit`. Red: the e2e test + asserting `whitaker --help` exits 0 fails against a naive `Err => 1` + implementation. +- **Non-vacuity.** The e2e test spawns the real binary through + `env!("CARGO_BIN_EXE_whitaker")` and reads `ExitStatus::code()`, so a + mapping that is correct in a unit but unwired in `main` is caught. Negative + control: drop the `is_display_request` branch; `whitaker --help` must then + exit 1 and the test must fail. + +### EP-LEM-NAME — release-asset name unambiguity + +- **Obligation.** The composed release-asset name + `{name}-{target}-v{version}.{ext}` determines `(name, target, version)` + uniquely. Formally: for well-formed field triples `(n₁,t₁,vs₁)` and + `(n₂,t₂,vs₂)` drawn from the admissible alphabets, if + `compose(n₁,t₁,vs₁) = compose(n₂,t₂,vs₂)` then the triples are equal. +- **Method.** Formal proof (Verus), plus a `proptest` differential check + against the Rust implementation. +- **Rationale.** This is a genuine new obligation created by this change, not + a restatement. Before this plan only `whitaker-installer` published under + this template. Adding `whitaker` — a **proper prefix** of + `whitaker-installer` — into a template whose separator `-` also occurs + inside every target triple creates a real ambiguity hazard: a wrong split + means `cargo binstall whitaker` silently fetches the installer's archive. + The guarantee must hold for all admissible inputs, not a sampled subset, so + a prover rather than a property test is the right instrument; the property + test then ties the proven model back to the Rust code. +- **Domain.** Unbounded. `name` over `[a-z0-9_-]+` drawn from the published + package set; `target` a Rust target triple; `version` a semantic version + string. The proof proceeds by showing the `-v` delimiter preceding the + version cannot occur inside a well-formed target triple, which pins the + version boundary, and that the package-name set is prefix-free **once the + following separator is included** — the non-obvious step, and the one that + fails if a future package is named such that the property breaks. +- **Artefact.** `verus/whitaker_artefact_naming.rs`, added to the + `decomposition`/`clone-detector` group structure in `scripts/run-verus.sh` + as a new `packaging` group. +- **Evidence.** `make verus 2>&1 | tee /tmp/verus-whitaker-3-5-1.out`. Expect + `verification results:: N verified, 0 errors`. +- **Non-vacuity.** The proof must not assume its conclusion. Inspect it for + `assume`: there must be none in the final version, and the well-formedness + predicates must be shown _inhabited_ by an explicit witness lemma exhibiting + a concrete satisfying triple (`whitaker`, `x86_64-unknown-linux-gnu`, + `0.2.7`) before the injectivity theorem is stated — otherwise the theorem is + vacuously true over an empty domain. Negative control: weaken the + well-formedness predicate to permit a package name containing `-v` followed + by digits; the injectivity proof must then fail. Record that failure + transcript before restoring the predicate. + +### Deliberately not verified + +- The internals of `clap`, `ortho_config`, `figment`, or `cargo-binstall`. +- The installer's existing behaviour beyond parity. This plan asserts the new + binary matches the old one; it does not re-verify what the old one does. + That is already covered by `installer/tests/`. +- Localization catalogue content. `EP-M2` wires `NoOpLocalizer`, so there is + no translation logic to verify. Fluent catalogues arrive with roadmap 3.6.4. + +## Plan of work + +### Stage A — prototype and decide (EP-M0, no production code) + +Answer `Risk R1` before designing around either outcome. Create a throwaway +`src/main.rs` in the root package containing only: + +```rust +//! Feasibility spike: does a root-package binary build under --all-features? +fn main() { println!("spike"); } +``` + +Then run, capturing output: + +```console +cargo check -p whitaker --bins --all-features 2>&1 | tee /tmp/spike-a.out +cargo check --workspace --all-targets --all-features 2>&1 | tee /tmp/spike-b.out +``` + +Then add `use whitaker::greet;` and a call to it, and repeat, because a bin +that never references the library may not link it — which would make the first +result misleading: + +```console +cargo check -p whitaker --bins --all-features 2>&1 | tee /tmp/spike-c.out +``` + +Go/no-go: + +- **Both succeed:** proceed to Stage B with the binary in the root package. +- **Either fails with duplicate `std`/`core` symbols:** delete the spike file, + record the transcript in `Surprises & discoveries`, set status `BLOCKED`, + and escalate with the `Risk R1` options. Do not proceed. + +Delete the spike file before Stage B regardless of outcome. + +### Stage B — red tests and feature specifications + +No production behaviour yet. Write the failing specifications first. + +Create the crate skeleton `crates/whitaker_cli/` with `src/lib.rs` containing +only module declarations and doc comments, and add it to the workspace. Add +the four dependencies. Then write, in this order: + +1. `crates/whitaker_cli/tests/features/whitaker_cli.feature` — the Gherkin + specification, reproduced in full under `Artefacts and notes`. +2. `crates/whitaker_cli/tests/behaviour_cli.rs` with step definitions and a + `CliWorld` fixture modelled on `installer/tests/behaviour_cli/support.rs`. +3. `crates/whitaker_cli/tests/e2e_exit_codes.rs` (`EP-INV-EXIT`). +4. `crates/whitaker_cli/tests/property_arg_parity.rs` (`EP-INV-PARITY`). +5. `crates/whitaker_cli/src/domain/routing/kani.rs` (`EP-INV-ROUTE`), plus the + three reachability harnesses. +6. `verus/whitaker_artefact_naming.rs` (`EP-LEM-NAME`), starting with the + witness lemma. + +Validation for Stage B: every one of the above must **fail**, and the failure +must be the expected one. Record each red transcript. A test that fails +because a module does not exist is acceptable only for the compile-time +skeleton; the behavioural and property tests must reach a genuine assertion +failure once the skeleton compiles. + +### Stage C — implementation + +Build the library, then the binary, then the packaging metadata. Each step +below names its file and what goes in it; see `Interfaces and dependencies` +for exact signatures. + +1. **Promote the binary-private orchestration.** In `installer/src/lib.rs`, + add `pub mod install_flow;` and move `installer/src/install_flow/` into the + library. Move the orchestration functions currently in + `installer/src/main.rs` (`run_install`, `run_dry`, + `try_fast_path_installation`, `finish_install`, + `finish_install_and_record_metrics`, `resolve_requested_crates`, + `generate_and_report_wrapper`, `ensure_whitaker_workspace`, + `resolve_toolchain`, `ensure_toolchain_installed`) into a new + `installer/src/orchestration/` module tree, each file under 400 lines. + Leave `staged_suite` binary-private (`Risk R5`); expose only the single + entry point the fast path needs, behind its existing gating. + `installer/src/main.rs` becomes a thin composition root calling the + library. **No behaviour changes.** Run `make test` here: every existing + `installer/tests/` test must pass **unmodified**. If any assertion needs + changing, that is a Constraint 1 breach — stop. + +2. **Define the domain and ports** in `crates/whitaker_cli/src/domain/` and + `crates/whitaker_cli/src/ports/`. The domain owns `Request`, `Outcome`, + `ExitCode`, the routing function, and the exit-code policy. It imports + nothing from `std::process`, `std::fs`, or `whitaker_installer`. This is + the dependency rule, and it is checkable: `crates/whitaker_cli/src/domain/` + must contain no `use whitaker_installer` and no `use std::{fs, process}`. + +3. **Define the driving adapter** in `crates/whitaker_cli/src/cli/`: the clap + `Parser`/`Subcommand`/`Args` structs for `whitaker`, `whitaker install`, + and `whitaker ls`, mirroring `installer/src/cli.rs` field for field, plus + the `ortho_config` localized-parse entry point. + +4. **Define the driven adapters** in `crates/whitaker_cli/src/adapters/`, + implementing the ports over `whitaker_installer`'s now-public + orchestration. + +5. **Add the composition root** at `src/main.rs` in the root package: build + the adapters, call `whitaker_cli::run`, map the outcome to a process exit + code. Target under 60 lines. Declare `[[bin]] name = "whitaker"` with + `autobins = false` in the root `Cargo.toml`, matching the convention at + `installer/Cargo.toml:11-27`. + +6. **Remove `--exclude whitaker` from `TEST_EXCLUDES`** if and only if + `EP-M0` showed the package tests cleanly; otherwise leave it and note in + `Surprises & discoveries` that root-package tests remain excluded, with all + `whitaker_cli` tests living in the non-excluded crate (which is why they + were put there). + +7. **Add binstall metadata.** Parameterize + `installer/src/binstall_metadata.rs` over the package name rather than + hardcoding `"whitaker-installer"` (currently at lines 52 and 77), and add + the `[package.metadata.binstall]` block to the root `Cargo.toml` mirroring + `installer/Cargo.toml:95-101`, including the + `overrides.x86_64-pc-windows-msvc` entry with `pkg-fmt = "zip"`. + +Validation after each numbered step: `make check-fmt && make typecheck && +make lint && make test`, captured with `tee`. Commit after each step. + +### Stage D — verification, documentation, and wider validation + +1. Turn the Verus proof green; run the negative control and record it. +2. Turn the Kani harnesses green; run the negative control and record it. +3. Run the `proptest` non-vacuity classification report and confirm every flag + is exercised. +4. Write the ADR (`EP-M4`). +5. Update `docs/users-guide.md`, `docs/developers-guide.md`, + `docs/whitaker-cli-design.md`, `docs/whitaker-dylint-suite-design.md`, and + `docs/roadmap.md`. +6. Run `make markdownlint` and `make nixie`. + +## Milestones and plateaus + +### EP-M0 — feasibility established (prototyping) + +- **Outcome.** A recorded, evidence-backed answer to whether the `whitaker` + binary can live in the root package.

From ed2ec829c910e05a70097d783750024633ee566e Mon Sep 17 00:00:00 2001 From: leynos Date: Fri, 21 Aug 2026 18:22:37 +0200 Subject: [PATCH 03/13] Rewrite 3.5.1 execplan after design review A six-perspective review invalidated the first draft's structural bet. `cargo package -p whitaker` fails: the root package depends on four `publish = false` rustc shim crates and lacks crates.io metadata, so `cargo install whitaker` was unreachable. Extracting the Dylint driver library into `crates/whitaker_lint_core` is therefore a precondition, not a contingency, and it is now milestone EP-M0. That removes the need for a separate CLI crate, makes `CARGO_BIN_EXE_whitaker` available to the end-to-end tests, and confines `ortho_config` to the CLI binary. Record the `whitaker` name collision the first draft missed: the installer generates an executable named `whitaker` that a `cargo install`ed binary deterministically shadows, breaking `whitaker --all` and this repository's own `make lint`. The binary now forwards unrecognized arguments to `cargo dylint`. Cut both original verification obligations as vacuous. Nothing inverts a release-asset name, and clap rejects the flag conflicts before any repository-owned routing code runs. Verify argv classification totality and disjointness instead, bounded by Kani and closed unbounded by Verus. Settle exit codes at 0, 2, and 1.

So `cargo install whitaker` + cannot resolve — the headline outcome is unreachable until this is fixed. +2. **The installer's orchestration is trapped inside a binary target.** Ten + functions in `installer/src/main.rs` and two binary-private modules cannot + be called by any other program or tested directly. + +The commands `whitaker check` and `whitaker doctor` are **not** in this plan; +they are separate roadmap items that depend on this one. ## Definitions -Terms used throughout, defined here so no prior knowledge is assumed. +Defined here so no prior knowledge is assumed. **Dylint.** A tool that runs custom Rust lints compiled as dynamic libraries. Whitaker's lints are Dylint lints. `cargo-dylint` and `dylint-link` are the -two helper binaries Dylint needs. +helper binaries it needs. -**Lint bundle / staged library.** A compiled Dylint lint library copied into a -known directory with a filename encoding the toolchain it was built for. -"Staging" is the act of copying it there. +**Dylint driver.** Code that links the private `rustc_*` compiler crates and +therefore needs `#![feature(rustc_private)]` and a nightly toolchain. It is +contagious: anything depending on it inherits the constraint. + +**Lint bundle / staged library.** A compiled lint library copied into a known +directory under a filename encoding the toolchain it was built for. **Prebuilt artefact.** A `.tar.zst` archive of already-compiled lint libraries -published on GitHub Releases, so users do not have to compile lints locally. +published on GitHub Releases, so users need not compile lints locally. + +**`cargo-binstall`.** Installs a Rust binary by downloading a prebuilt release +archive rather than compiling. It reads `[package.metadata.binstall]` from the +package's manifest **as published on crates.io**. + +**Wrapper script.** The executable file named `whitaker` that +`installer/src/wrapper.rs` writes into the user's binary directory. Its whole +body sets `DYLINT_LIBRARY_PATH` and runs `exec cargo dylint "$@"`. + +**Port / adapter (hexagonal architecture).** A port is a trait, owned by the +policy layer, describing something it needs from the outside world. An adapter +implements it. A _driving_ adapter calls into the policy (the CLI parser); a +_driven_ adapter is called by it (the installer). + +**Composition root.** The one place — `src/main.rs` — where concrete adapters +are constructed. Nothing else selects implementations. + +**Plateau.** A milestone leaving the repository correct, coherent, and safe to +stop at. + +## Progress -**`cargo-binstall`.** A tool that installs a Rust binary by downloading a -prebuilt release archive instead of compiling.

Split any partially completed +item into "done" and "remaining" rather than leaving it ambiguous. -**Adapter.** A concrete implementation of a port that does the real work, for -example by spawning a process or writing a file. +## Constraints + +Hard invariants. Violation requires escalation, not a workaround. + +1. **`whitaker-installer` keeps working unchanged.** Its command-line surface, + exit codes, and output must be identical before and after. It is a released + binary documented in `docs/users-guide.md`, published to GitHub Releases, + exercised by `make install-smoke` and `installer/tests/`. Its deprecation + is roadmap 3.9.1, not this plan. This is not a shim invented to make a + milestone viable; it is the shipping product. +2. **`whitaker --all` keeps working.** The wrapper script's contract is + documented at `docs/users-guide.md:25-27` and consumed by `Makefile:185` + and `.github/workflows/ci.yml:154`. Named consumers: existing users, and + this repository's own lint gate. +3. **The public library surface of `whitaker_installer` must not shrink.** + Integration tests under `installer/tests/` compile against it as an + external crate and see only `pub` items; `installer/Cargo.toml:29-55` gates + `StubExecutor` and `InstallerError::StubMismatch` behind the `test-support` + feature, which roadmap 3.2.2 declares supported. Additions are fine; + removals and signature narrowings are not. +4. **The root package stays named `whitaker` at version `0.2.7`**, and the new + binary is named `whitaker`. +5. **The Dylint lint crates must keep building and their UI tests passing** + throughout `EP-M0`. They are the oracle for that milestone. +6. **No new lint suppressions.** `Cargo.toml [workspace.lints]` sets + `unsafe_code = "forbid"`, `missing_docs = "deny"`, `allow_attributes = + "deny"`, clippy `pedantic` at warn with `-D warnings`. Adding `#[allow(…)]` + to pass a gate is a tolerance breach. Adding an `excluded_crates` entry to + `dylint.toml` counts as a suppression for this purpose and requires the + same escalation. +7. **No file may exceed 400 lines** (`AGENTS.md`). Every module needs a `//!` + doc comment. +8. **No direct environment mutation in tests** (`AGENTS.md`). Use `temp-env` + or inject through a port. +9. **The prebuilt-artefact path must not change behaviour.** Governed by + `docs/adr-001-prebuilt-dylint-libraries.md`. +10. **Caret dependency requirements only**; no `*` or `>=`. + +## Tolerances (exception triggers) -**Composition root.** The single place — here, `src/main.rs` — where concrete -adapters are constructed and handed to the domain. Nothing else in the program -chooses implementations. +Stop and escalate; do not improvise. + +- **Scope.** More than 70 files changed, or more than 2,500 net added lines. + `EP-M0` alone touches roughly 40 files, almost all mechanically. +- **`EP-M0` gate.** If `cargo package -p whitaker --no-verify` still fails + after the extraction, stop. That command is the milestone's whole point. +- **Interface.** If anything requires removing or narrowing an existing `pub` + item in `whitaker_installer`, stop (Constraint 3). Additive `*_for` + functions are the sanctioned pattern. +- **Behaviour drift.** If any existing test under `installer/tests/` or any + Dylint UI fixture needs its _assertions_ changed, stop. Relocation is fine; + changed expectations are evidence of a Constraint 1 or 5 breach. +- **Dependencies.** Three new dependencies are pre-authorized: `ortho_config`, + `googletest`, `pretty_assertions`. A fourth triggers escalation. +- **Iterations.** Three failed fix attempts on one root cause; report the log + path. +- **Verification.** Kani over 15 minutes for this plan's harnesses in + aggregate, or Verus over 10 minutes, or more than one working day spent + authoring either. These are the repository's first sequence-shaped proofs; + budget overrun is the expected failure mode. +- **Ambiguity.** If `docs/whitaker-cli-design.md` and `docs/roadmap.md` + disagree on whether a behaviour belongs to 3.5.1, stop and present both + readings. This fired twice during planning; see `Decision log` D-2 and D-3. -**Driving vs driven.** A _driving_ adapter calls into the domain (the CLI -parser). A _driven_ adapter is called by the domain (the installer). +## Risks -**ExecPlan plateau.** A milestone that leaves the repository correct, -coherent, and safe to stop at. +**R1 — `EP-M0` is a wide mechanical rename that can break the lint suite.** +Severity: high. Likelihood: medium. +Eleven lint-crate manifests and roughly 25 `use whitaker::` sites move. Note +`crates/test_must_not_have_example/Cargo.toml:34` uses a literal path +dependency, not the `workspace = true` alias, so a global search-and-replace +on the alias misses it. +Mitigation: the Dylint UI suite already exercises every affected crate. Run it +before and after and require identical results. Do the extraction as one +commit so bisection is clean. + +**R2 — Argument forwarding can swallow a real subcommand.** +Severity: high. Likelihood: medium. +The binary must decide, from argv alone, whether to dispatch a subcommand or +forward to `cargo dylint`. Get it wrong and `whitaker install` silently runs +`cargo dylint install`, or `whitaker --all` prints a usage error. +Mitigation: this is the plan's one genuinely new decision procedure, and it is +the subject of both verification obligations — `EP-INV-DISPATCH` (Kani) and +`EP-LEM-DISPATCH` (Verus). + +**R3 — Index-based BDD scenario bindings break silently.** +Severity: medium. Likelihood: medium. +`#[scenario(path = "…", index = N)]` binds by position; inserting a scenario +mid-file rebinds every later one, often still passing. See the warning at +`installer/tests/behaviour_cli/scenarios.rs:7`. +Mitigation: new scenarios go only in new feature files. + +**R4 — A new test binary named `behaviour_cli` is skipped by default.** +Severity: medium. Likelihood: high if unaddressed. +`.config/nextest.toml` sets +`default-filter = "not (binary(behaviour_toolchain) | binary(behaviour_cli) | kind(example))"`, +and nextest's `binary()` matches by binary _name_, not package-qualified name. +Mitigation: name the new file `behaviour_whitaker.rs`, and run +`make test NEXTEST_PROFILE=ci` at every milestone boundary. + +**R5 — `--help` and `--version` may exit non-zero.** +Severity: medium. Likelihood: medium. +clap reports both as `Err`. Routing every `Err` to a failure code makes +`whitaker --help` fail. +Mitigation: `EP-INV-EXIT`, asserted end-to-end on the real process. + +**R6 — Publishing instructions may precede name reservation.** +Severity: medium. Likelihood: low, but severe if it lands. +The name `whitaker` is unregistered on crates.io. If `EP-M4` publishes +`cargo install whitaker` before the name is claimed, and 3.5.3 slips, users +following official documentation install someone else's crate. +Mitigation: `EP-M3` reserves the name; `EP-M4` is explicitly gated behind it. + +**R7 — `ortho_config` brings a second `toml` stack.** +Severity: low. Likelihood: certain. +`ortho_config` 0.9.0 reaches `figment` → `toml 0.8` + `toml_edit 0.22` +alongside the workspace's existing `toml 1.x` + `toml_edit 0.25`, and enables +`figment`'s `test` feature (pulling `tempfile` and `parking_lot`) into the +production graph. Roughly 26 genuinely new lock entries; about 80% of the +closure is already present. +Mitigation: after `EP-M0` the root package is _not_ a dependency of the lint +crates, so this cost is confined to the CLI binary. Record the stripped +release size in `EP-M3` rather than guessing. + +**R8 — Removing `--exclude whitaker` switches on six never-run test binaries.** +Severity: medium. Likelihood: high. +`tests/{build_config,config_loading,lint_template,locale_resolution,nextest_ui_filter,ui_harness}.rs` +total roughly 1,045 lines and have never run under `make test`, because +`Makefile:23` excludes the package. `tests/ui_harness.rs` drives the Dylint UI +harness under `RUSTFLAGS="-C prefer-dynamic -Z force-unstable-if-unmarked +-D warnings"`. +Mitigation: treat this as its own step inside `EP-M0` with its own validation, +not a one-line edit. Note `Makefile:64-68` `DOCTEST_EXCLUDES` carries a +_second_ `--exclude whitaker`; decide both explicitly. `make coverage` +(`Makefile:151`) reuses the same recipe, so a bad landing reddens two CI jobs. ## Context and orientation -You have only this repository and this document.

Violation requires escalation, not a workaround. - -1. **`whitaker-installer` keeps working unchanged.** Its command-line surface, - exit codes, and output must be byte-identical before and after. It is a - released binary documented in `docs/users-guide.md`, published to GitHub - Releases, installed by `make install-smoke`, and exercised by - `installer/tests/behaviour_cli.rs`. `CLI-DESIGN` schedules its deprecation - for a later release (`CLI-REQ-SHIM`, roadmap 3.9.1), not this one. This is - not a compatibility shim invented to make a milestone viable: it is the - currently shipping product, and this plan adds a second entry point beside - it rather than replacing it. -2. **The public library surface of `whitaker_installer` must not shrink.** The - integration tests under `installer/tests/` compile against it as an - external crate and can only see `pub` items. `installer/Cargo.toml` lines - 29-55 gate `StubExecutor` and `InstallerError::StubMismatch` behind the - `test-support` feature, which roadmap item 3.2.2 declares a supported - surface for external test suites. Items may be added; existing ones may not - be removed or narrowed. -3. **The root package must remain named `whitaker` at version `0.2.7`**, and - the new binary must be named `whitaker`, so that `cargo install whitaker` - and `cargo binstall whitaker` resolve correctly. -4. **No new lint suppressions.** `Cargo.toml` `[workspace.lints]` sets - `unsafe_code = "forbid"`, `missing_docs = "deny"`, `allow_attributes = - "deny"` and clippy `pedantic` at warn with `-D warnings`. Adding - `#[allow(...)]` to get past a gate is a tolerance breach. -5. **No file may exceed 400 lines** (`AGENTS.md`). Every module needs a `//!` - doc comment. -6. **Direct environment mutation in tests is forbidden** (`AGENTS.md`). Use - `temp-env`, or dependency injection through a port. -7. **The prebuilt-artefact download path must not change behaviour.** It is - governed by `docs/adr-001-prebuilt-dylint-libraries.md` and by the release - workflow's published asset names. -8. **Caret dependency requirements only** (`AGENTS.md`); no `*` or `>=`. - -## Tolerances (exception triggers) - -Stop and escalate — do not improvise — when any of these is reached. - -- **Scope.** More than 45 files changed, or more than 2,500 net added lines - across the whole plan. The estimate is roughly 30 files and 1,800 lines. -- **Root-binary feasibility.** If `EP-M0` shows a binary in the root package - cannot build under `--all-features`, stop at the end of `EP-M0` and - escalate with the options in `Risk R1`. Do not silently relocate the binary - to a differently-named package: that would break `cargo install whitaker` - and violate Constraint 3. -- **Interface.** If discharging `CLI-REQ-LIB` requires removing or narrowing - any existing `pub` item in `whitaker_installer`, stop (Constraint 2). -- **Dependencies.** Four new dependencies are pre-authorized and listed in - `Interfaces and dependencies`: `ortho_config`, `googletest`, - `pretty_assertions`, and `insta` promoted to a root dev-dependency. Any - fifth new external dependency triggers escalation. -- **Iterations.** If a gate still fails after three fix attempts on the same - root cause, stop and escalate with the captured log path. -- **Verification.** If a Kani harness exceeds 15 minutes, or a Verus proof - exceeds 5 minutes, stop and escalate rather than raising the bound or the - timeout. -- **Behaviour drift.** If any existing `installer/tests/` test needs its - assertions changed (as opposed to being moved or added to), stop: that is - evidence of a Constraint 1 violation. -- **Ambiguity.** If `CLI-DESIGN` and `docs/roadmap.md` disagree on whether a - behaviour belongs to 3.5.1, stop and present both readings. - -## Risks - -**R1 — A binary in the root package may not build under `--all-features`.** -Severity: high. Likelihood: medium-high. -The root library sets `feature(rustc_private)` and links `rustc_driver` when -`dylint-driver` is enabled. `make typecheck`, `make lint`, and `make test` all -pass `--all-features`, which enables it. `src/lib.rs` records that all-features -test runs produce "duplicated `std`/`core` link errors", and `Makefile` line 24 -excludes the package from the test run for that reason. A binary target in the -same package may inherit the same failure. -Mitigation: `EP-M0` is a timeboxed prototyping milestone that answers this -empirically before any design is committed. If it fails, the recommended -remedy is to extract the Dylint driver library out of the root package into -`crates/whitaker_lint_core`, leaving the root package as the CLI package — -which permanently removes the conflict — but that is a scope increase -requiring approval, not an autonomous decision. - -**R2 — Index-based BDD scenario bindings break silently.** -Severity: medium. Likelihood: medium. -`#[scenario(path = "...", index = N)]` binds by position. Inserting a scenario -in the middle of an existing `.feature` file rebinds every later scenario to -the wrong step definitions, and the suite may still pass. -Mitigation: put all new scenarios in **new** feature files -(`crates/whitaker_cli/tests/features/*.feature`); never insert into -`installer/tests/features/installer.feature`. `EP-M2` acceptance includes -re-running `installer/tests/behaviour_cli.rs` unchanged. - -**R3 — Two packages publishing artefacts with one URL template may collide.** -Severity: high. Likelihood: low-medium. -`installer/Cargo.toml` lines 95-101 template the release URL as -`{name}-{target}-v{version}.{archive-format}`. Giving the `whitaker` package -the same pattern means two packages generate asset names from the same -template. Because `whitaker` is a proper prefix of `whitaker-installer`, and -target triples themselves contain `-`, an ambiguous split is conceivable. -Mitigation: `EP-LEM-NAME`, a Verus proof that the composed name determines its -fields uniquely, plus a `proptest` differential check. See `Verification -plan`. - -**R4 — `--help` and `--version` may exit non-zero.** -Severity: medium. Likelihood: medium. -clap reports `--help` as an `Err` variant. Routing every `Err` to exit code 1 -would make `whitaker --help` fail. `ortho_config::is_display_request` exists -precisely to distinguish this case, and it is easy to omit. -Mitigation: `EP-INV-EXIT` covers it with both a parameterized test and an -end-to-end assertion on the real process exit status. - -**R5 — Promoting binary-private modules widens the public API.** -Severity: medium. Likelihood: medium. -`install_flow` and `staged_suite` are binary-private today. Making them -reachable from a new crate could expose test-only machinery — `staged_suite` -in particular is a debug-only hook driven by the -`WHITAKER_INSTALLER_TEST_STAGE_SUITE` environment variable. -Mitigation: promote to `pub` only what the new ports need; keep -`staged_suite`'s hook behind the existing `#[cfg(debug_assertions)]` and -`test_support` gating; record the resulting surface in the `EP-M4` ADR. - -**R6 — `ortho_config` pulls a large dependency subtree.** -Severity: low. Likelihood: high (it is certain; the question is whether it -matters). `ortho_config` 0.9.0 depends on `figment`, `fluent-bundle`, -`fluent-syntax`, `unic-langid`, `clap-dispatch`, `directories`, `xdg`, and -more. -Mitigation: adopt it in this plan for localized parsing only, so the cost is -paid once at the point the roadmap already commits to it (item 3.6.3), not -twice. Confirm `make typecheck` build time does not regress by more than 30%; -report if it does. - -**R7 — Snapshot tests of `--help` are brittle across clap versions.** -Severity: low. Likelihood: medium. -`insta` snapshots of help text change whenever clap adjusts its formatting. -Mitigation: snapshot the _structure_ — the subcommand list and the option -names — rather than full rendered help; assert full text only for the -stable `ls --json` output, which is a machine contract. +Explicitly **not** discharged here, with owning roadmap items: `whitaker +check` (3.5.2); release-artefact publishing (3.5.3); rule codes and selector +precedence (3.6.1, 3.6.2); `whitaker.toml`, `dylint.toml` bridging and +`DYLINT_*` migration (3.6.3); `--locale`/`--colour`/`--progress` (3.6.4); the +`--build-only` → `--build-from-source` rename and `--offline` (3.7.1); bundle +manifests (3.7.3); `doctor` and failure recording (3.8.x); the full `ls` +surface (3.8.1, 3.8.2); the `whitaker-installer` deprecation shim and `list` +alias (3.9.1); wrapper-script and `--skip-wrapper` removal (3.9.3). ## Verification plan -This change is mostly a refactor plus a new entry point, so it would be easy -to claim it introduces no invariants. That is not true, and saying so would be -the vacuous option. Three genuine obligations arise, and one lemma. - -### Axioms (assumed, not verified here) - -- `clap` 4.5 parses an argument vector into the derived struct according to - its documented derive semantics. Third-party internals are not verified. +The first draft proposed a Verus proof of release-asset-name injectivity and a +Kani harness proving that a routing function rejects two conflicting flag +pairs. Both were **vacuous** and have been cut. Nothing in this repository +ever inverts an asset name — `cargo-binstall` composes by literal +substitution, and a grep for `rsplit_once|splitn|strip_prefix` across +`installer/src/` finds nothing — so injectivity of a never-inverted function +is load-bearing for nothing. And both conflict pairs are enforced by clap +attributes (`installer/src/cli.rs:108`, `:113`, `:131`), which reject the +input during parsing, so a routing function can never receive one; proving it +rejects them proves a property of an unreachable branch. Recording this is +required by the ExecPlan discipline: a passing check that cannot fail is not +evidence. + +What replaced them is a genuinely new obligation. The forwarding behaviour +(`CLI-REQ-FWD`) introduces a decision procedure that did not previously exist +and that no third-party library owns: given argv, dispatch a subcommand or +forward to `cargo dylint`. Getting it wrong silently breaks either the new CLI +or every existing user. That is worth verifying properly. + +### Axioms (assumed, not verified) + +- `clap` 4.5 parses argv per its documented derive semantics. - `ortho_config` 0.9.0's `LocalizedParse::try_parse_localized_from` and `is_display_request` behave as documented. Repository-owned logic built on them **is** verified, against the real interface. -- `cargo-binstall` resolves `pkg-url` by substituting `{name}`, `{target}`, - `{version}`, and `{archive-format}` literally. -- The GitHub release workflow publishes assets under exactly the names - produced by `installer/src/artefact/naming.rs`. -- Kani sequentializes concurrency; no obligation below concerns concurrency. - -### EP-INV-PARITY — install-argument parity - -- **Obligation.** For every argument vector `v` that `whitaker-installer` - accepts as an install invocation, `whitaker install v` parses to an - `InstallRequest` equal to the one `whitaker-installer` produces from `v`; - and for every `v` that `whitaker-installer` rejects, `whitaker install v` is - rejected too. -- **Method.** Property test (`proptest`), differential. -- **Rationale.** This is the precise formal content of "move the current - installer behaviour behind a library boundary _without changing it_". The - flag surface has 14 options with two documented conflict pairs; enumerating - it by hand would miss combinations, and the space is far too large for - bounded model checking over strings. -- **Domain.** Generated argument vectors over the 14 flags declared in - `installer/src/cli.rs:77-181`, including repeated `--lint`, repeated `-v`, - the `--lint` / `--individual-lints` conflict, the `-v` / `-q` conflict, - paths containing spaces and non-ASCII characters, and empty values. -- **Artefact.** `crates/whitaker_cli/tests/property_arg_parity.rs`. -- **Evidence.** `cargo nextest run -p whitaker_cli property_arg_parity`. Red - stage: written before the mapping exists, so it fails to compile, then fails - on a deliberately incomplete mapping that drops `--jobs`. Discharged when it - passes with 1,024 generated cases and the regression file is committed. -- **Non-vacuity.** The generator must be _classified_: record via - `proptest::prop_assume!`-free construction and explicit - `Strategy::prop_map` that each of the 14 flags appears set in at least 5% of - cases, that both conflict pairs are generated, and that at least one case - has zero flags. A run where any flag is never exercised is a **failure**, - not a pass. Negative control: temporarily drop `--no-update` from the - `whitaker install` mapping; the test must fail naming that flag. Restore - afterwards and record the transcript. - -### EP-INV-ROUTE — routing totality and conflict rejection - -- **Obligation.** The function mapping a parsed CLI to a domain `Request` is - total (never panics, never returns a "cannot happen" error) over all - reachable flag combinations, and rejects exactly the two documented conflict - pairs. -- **Method.** Bounded model check (Kani), complemented by parameterized - `rstest` cases. -- **Rationale.** Totality over a combinatorial flag space is exactly what - bounded exhaustive exploration is for, and the space is small enough to - explore completely once flags are modelled as booleans rather than strings. - A property test would sample it; Kani covers it. -- **Domain.** The boolean flags modelled as a bitmask, plus a bounded - `Option` for `--jobs` and a bounded 0-3 count for `-v`. Ten booleans - gives 1,024 states; with the two bounded integers the harness explores under - 10^5 states, well inside Kani's practical range for non-heap types. - `#[kani::unwind(4)]` bounds the single loop over requested lints, capped at - three entries. -- **Artefact.** `crates/whitaker_cli/src/domain/routing/kani.rs`, gated - `#[cfg(kani)]`, registered in `scripts/run-kani.sh` alongside the existing - named harnesses. +- `cargo-binstall` resolves `pkg-url` by literal substitution of `{name}`, + `{target}`, `{version}`, `{archive-format}`. +- The wrapper script's contract is `exec cargo dylint "$@"` with + `DYLINT_LIBRARY_PATH` set (`installer/src/wrapper.rs:107-113`). +- Kani sequentializes concurrency; no obligation here concerns concurrency. + +### `EP-INV-DISPATCH` — argv classification is total and disjoint (bounded) + +- **Obligation.** For every argv, `classify(argv)` returns exactly one of + `Subcommand(_)`, `Forward`, or `Display`. No argv whose first non-global + token names a Whitaker subcommand is ever classified `Forward`, and no argv + the wrapper script would have accepted is classified as a usage error. +- **Method.** Bounded model check (Kani), plus parameterized `rstest` cases. +- **Rationale.** Totality and disjointness over a combinatorial token space is + what bounded exhaustive exploration is for, and `classify` is small and pure. +- **Domain.** argv modelled as a bounded sequence of _token tags_, not + strings: an enum over `{Install, Ls, Help, Version, DoubleDash, GlobalFlag, + DylintFlag, Other}`, length bounded at 6 — under 10^5 states. + `#[kani::unwind(7)]`, one greater than the maximum iteration count. +- **Siting.** `classify` and its token enum live in `src/cli/dispatch.rs` in + the root package and take the token enum rather than `clap::Cli`, so the + harness compiles a small pure module. This is deliberate: siting Kani where + it must codegen `clap` plus `ortho_config` plus `whitaker_installer` would + be a roughly 250-crate graph, and a symbolic `Vec` hits the + documented heap cliff. Tokenizing real argv is a separate, testable function + that is _not_ part of the harness. +- **Artefact.** `src/cli/dispatch.rs`, `#[cfg(kani)] mod verification`. + Register a new `whitaker-cli` group in `scripts/run-kani.sh`, adding both a + group function and a `case` arm. **Note the `*)` fallback at + `scripts/run-kani.sh:97` routes unrecognized arguments into the + _decomposition_ group**, so a mistyped filter silently verifies the wrong + package and reports success. Add the arm before the fallback and confirm the + harness names appear in the output. - **Evidence.** `make kani 2>&1 | tee /tmp/kani-whitaker-3-5-1.out`. Expect - `VERIFICATION:- SUCCESSFUL` for - `verify_route_request_is_total_over_bounded_flags` and - `verify_route_request_rejects_documented_conflicts`. -- **Non-vacuity.** The harness must drive the **production** routing function, - not a re-implementation. Assumptions must not collapse the space: assert - before the main property that at least one satisfying assignment reaches - each of the three routing outcomes (install, list, conflict-rejected) by - running three separate `#[kani::proof]` reachability harnesses that assert - `false` under a constraint selecting that outcome, and confirming each - reports a counterexample — proving the branch is reachable. Negative - control: remove the `--lint` / `--individual-lints` conflict check from the - production function; `verify_route_request_rejects_documented_conflicts` - must fail with a concrete counterexample. Restore and record. - -### EP-INV-EXIT — exit-code policy - -- **Obligation.** The process exit code is `0` for success and for a clap - display request (`--help`, `--version`); `1` for an operational failure. No - input produces any other code, and no display request produces a non-zero - code. -- **Method.** Parameterized tests (`rstest` with `googletest` matchers) over - the finite partition of outcome kinds, plus an end-to-end assertion on the - real spawned process. -- **Rationale.** The outcome space is a small finite partition — the natural - fit for parameterized testing. The end-to-end case is what makes it - non-vacuous, because the unit-level mapping can be right while `main` - discards it. -- **Domain.** Every variant class of `InstallerError` grouped by kind, plus - `Ok(())`, plus clap `ErrorKind::DisplayHelp` and `DisplayVersion`, plus a - genuine parse error. -- **Artefact.** `crates/whitaker_cli/src/domain/exit_tests.rs` and - `crates/whitaker_cli/tests/e2e_exit_codes.rs`. -- **Evidence.** `cargo nextest run -p whitaker_cli exit`. Red: the e2e test - asserting `whitaker --help` exits 0 fails against a naive `Err => 1` - implementation. -- **Non-vacuity.** The e2e test spawns the real binary through - `env!("CARGO_BIN_EXE_whitaker")` and reads `ExitStatus::code()`, so a - mapping that is correct in a unit but unwired in `main` is caught. Negative - control: drop the `is_display_request` branch; `whitaker --help` must then - exit 1 and the test must fail. - -### EP-LEM-NAME — release-asset name unambiguity - -- **Obligation.** The composed release-asset name - `{name}-{target}-v{version}.{ext}` determines `(name, target, version)` - uniquely. Formally: for well-formed field triples `(n₁,t₁,vs₁)` and - `(n₂,t₂,vs₂)` drawn from the admissible alphabets, if - `compose(n₁,t₁,vs₁) = compose(n₂,t₂,vs₂)` then the triples are equal. -- **Method.** Formal proof (Verus), plus a `proptest` differential check - against the Rust implementation. -- **Rationale.** This is a genuine new obligation created by this change, not - a restatement. Before this plan only `whitaker-installer` published under - this template. Adding `whitaker` — a **proper prefix** of - `whitaker-installer` — into a template whose separator `-` also occurs - inside every target triple creates a real ambiguity hazard: a wrong split - means `cargo binstall whitaker` silently fetches the installer's archive. - The guarantee must hold for all admissible inputs, not a sampled subset, so - a prover rather than a property test is the right instrument; the property - test then ties the proven model back to the Rust code. -- **Domain.** Unbounded. `name` over `[a-z0-9_-]+` drawn from the published - package set; `target` a Rust target triple; `version` a semantic version - string. The proof proceeds by showing the `-v` delimiter preceding the - version cannot occur inside a well-formed target triple, which pins the - version boundary, and that the package-name set is prefix-free **once the - following separator is included** — the non-obvious step, and the one that - fails if a future package is named such that the property breaks. -- **Artefact.** `verus/whitaker_artefact_naming.rs`, added to the - `decomposition`/`clone-detector` group structure in `scripts/run-verus.sh` - as a new `packaging` group. + `VERIFICATION:- SUCCESSFUL` for `verify_classify_is_total_and_disjoint`. +- **Non-vacuity.** Three separate reachability harnesses each assert `false` + under a constraint selecting one outcome; each **must report a + counterexample**, proving that outcome reachable. A harness that verifies + successfully here is a failure. Negative control: remove `Ls` from the + subcommand table; `verify_classify_is_total_and_disjoint` must fail with a + concrete argv that names `ls` yet classifies as `Forward`. Restore and + record the transcript. + +### `EP-LEM-DISPATCH` — classification is total for unbounded argv + +- **Obligation.** For every finite token sequence of _any_ length, exactly one + classification applies. Kani bounds length at 6; this closes the tail. +- **Method.** Formal proof (Verus) over `Seq`. +- **Rationale.** The guarantee must hold for all admissible inputs — a user's + `cargo dylint` invocation has no length bound. Bounded checking cannot + establish it. The proof is a genuine mutual-exclusivity and exhaustiveness + argument over the guard predicates, not a restatement. +- **Domain.** Unbounded `Seq`. This would be the repository's first + sequence-shaped proof; every file in `verus/` today is numeric or + vector-algebraic. Budget accordingly and respect the verification tolerance. +- **Artefact.** `verus/whitaker_cli_dispatch.rs`, added as a new `cli` group + in `scripts/run-verus.sh` — which needs **both** the `case` at `:10-26` and + the second `case` at `:53-54` edited, not one. - **Evidence.** `make verus 2>&1 | tee /tmp/verus-whitaker-3-5-1.out`. Expect `verification results:: N verified, 0 errors`. -- **Non-vacuity.** The proof must not assume its conclusion. Inspect it for - `assume`: there must be none in the final version, and the well-formedness - predicates must be shown _inhabited_ by an explicit witness lemma exhibiting - a concrete satisfying triple (`whitaker`, `x86_64-unknown-linux-gnu`, - `0.2.7`) before the injectivity theorem is stated — otherwise the theorem is - vacuously true over an empty domain. Negative control: weaken the - well-formedness predicate to permit a package name containing `-v` followed - by digits; the injectivity proof must then fail. Record that failure - transcript before restoring the predicate. - -### Deliberately not verified - -- The internals of `clap`, `ortho_config`, `figment`, or `cargo-binstall`. -- The installer's existing behaviour beyond parity. This plan asserts the new - binary matches the old one; it does not re-verify what the old one does. - That is already covered by `installer/tests/`. -- Localization catalogue content. `EP-M2` wires `NoOpLocalizer`, so there is - no translation logic to verify. Fluent catalogues arrive with roadmap 3.6.4. +- **Non-vacuity.** No `assume` in the final proof. A witness lemma must + exhibit an inhabiting sequence for each of the three classes _before_ the + disjointness theorem is stated, or the theorem is vacuously true over an + empty domain. Negative control: widen one guard so two overlap; the + disjointness proof must fail. Record that transcript before restoring. + +### `EP-INV-PARITY` — install-argument parity + +- **Obligation.** For every argv `v` that `whitaker-installer` accepts as an + install invocation, `whitaker install v` produces an equal `InstallRequest`; + and every `v` the installer rejects, `whitaker install v` rejects with the + same exit code. +- **Method.** Differential property test (`proptest`). +- **Rationale.** This is the precise formal content of "move the behaviour + without changing it". Fourteen options with two conflict pairs is far too + large to enumerate and too string-shaped for a model checker. +- **Domain.** Generated argv over the 14 options declared across `InstallArgs` + (`installer/src/cli.rs:77-123`) and its three `#[command(flatten)]` groups + `LintSelectionFlags` (`:129`), `ExecutionFlags` (`:143`), `SkipFlags` + (`:157`). **Must include** short forms (`-t`, `-l`, `-j`, `-v`, `-q`), the + long alias `--verbosity` (`:107`), repeated `--lint`, repeated `-v`, both + conflict pairs, paths with spaces and non-ASCII characters, and the explicit + `whitaker-installer install …` form as well as the bare form. +- **Artefact.** `tests/property_arg_parity.rs` in the root package. +- **Evidence.** `cargo nextest run -p whitaker property_arg_parity`. Red: a + deliberately incomplete mapping that drops `--jobs` must fail naming it. +- **Non-vacuity.** Classify on **pairs**, not single flags: 2^14 is 16,384 + subsets, so marginal per-flag coverage says nothing about the combinations + where the conflicts live. Require every unordered pair of options to co-occur + in at least one case, and every option to appear set in at least 5% of cases. + Run 4,096 cases — clap parsing is tens of microseconds, so this costs well + under a second. A run where any pair is never exercised is a **failure**. + Negative control: drop `--no-update` from the mapping; the test must fail + naming it. + +### `EP-INV-EXIT` — exit-code policy + +- **Obligation.** Exit `0` for success and for a clap display request + (`--help`, `--version`); **`2` for an argument-parsing or usage error**; `1` + for an operational failure. Forwarded invocations propagate `cargo dylint`'s + exit code unchanged. +- **Method.** Parameterized `rstest` over the finite partition, plus + end-to-end assertions on the real spawned process. +- **Rationale.** A small finite partition is exactly what parameterized tests + are for. The end-to-end case is what makes it non-vacuous: the unit mapping + can be right while `main` discards it. +- **Ground truth, not a free choice.** `installer/src/main.rs:42` calls + `Cli::parse()`, whose `Error::exit()` terminates with clap's code — **2** — + never reaching `exit_code_for_run_result` at `:391-398`, the only source of + `1`. So `whitaker-installer --lint x --individual-lints` exits 2 today, and + Constraint 1 plus `EP-INV-PARITY` require `whitaker install` to match. The + localized-parse arm must therefore use clap's own code, not a blanket + failure code. +- **Domain.** `Ok(())`; each variant class of `InstallerError`; clap + `DisplayHelp` and `DisplayVersion`; a genuine usage error; a forwarded + invocation returning a non-zero code. +- **Artefact.** `src/cli/exit.rs` unit tests and `tests/e2e_exit_codes.rs`, + **both in the root package** — because `env!("CARGO_BIN_EXE_whitaker")` is + defined only for integration tests of the package declaring the binary. This + is why `EP-M0` must remove `--exclude whitaker` from `TEST_EXCLUDES`; the + end-to-end obligation is otherwise unrunnable. +- **Evidence.** `cargo nextest run -p whitaker exit`. +- **Non-vacuity.** The end-to-end test spawns the real binary and reads + `ExitStatus::code()`. Negative control: drop the `is_display_request` branch; + `whitaker --help` must then exit non-zero and the test must fail. + +### Not verified, deliberately + +- Internals of `clap`, `ortho_config`, `figment`, or `cargo-binstall`. +- The installer's existing behaviour beyond parity — already covered by + `installer/tests/`. +- Localization catalogue content: `EP-M2` wires `NoOpLocalizer`, so there is + no translation logic yet. Catalogues arrive with 3.6.4. ## Plan of work -### Stage A — prototype and decide (EP-M0, no production code) - -Answer `Risk R1` before designing around either outcome. Create a throwaway -`src/main.rs` in the root package containing only: - -```rust -//! Feasibility spike: does a root-package binary build under --all-features? -fn main() { println!("spike"); } -``` - -Then run, capturing output: +### Stage A — extract the driver library (`EP-M0`) + +This is the precondition, not a spike. Do it first and completely. + +1. Create `crates/whitaker_lint_core` and move `src/config.rs`, `src/hir/`, + `src/lints/`, `src/testing/`, the `dylint-driver` feature, and the root + `tests/` files that exercise them (`build_config.rs`, `config_loading.rs`, + `lint_template.rs`, `locale_resolution.rs`, `nextest_ui_filter.rs`, + `ui_harness.rs`, plus `tests/features/` and `tests/support/`). +2. Repoint the eleven lint-crate manifests and `suite/`. Do not miss the + literal path dependency at + `crates/test_must_not_have_example/Cargo.toml:34`. +3. Strip the root `[package]` to a CLI package and add what crates.io + requires: `description`, `license.workspace = true`, + `repository.workspace = true`, `homepage.workspace = true`, + `documentation.workspace = true`. Remove the now-unused optional `rustc_*` + dependencies and the `dylint-driver` feature. **Also remove the unused + `whitaker-installer` dependency at `Cargo.toml:71`** — grep confirms zero + `whitaker_installer::` references under `src/` or `tests/` today — and + re-add it deliberately in `EP-M1`, so the before-and-after dependency + measurement is honest. +4. Remove `--exclude whitaker` from `TEST_EXCLUDES` (`Makefile:23`) **and** + decide `DOCTEST_EXCLUDES` (`Makefile:64-68`) explicitly. Expect R8: six + test binaries begin running for the first time. Fix what they surface; if + any fails for a pre-existing reason unrelated to this plan, record it in + `Surprises & discoveries` and escalate rather than papering over it. +5. Add `-p whitaker` to `WHITAKER_PACKAGES` (`Makefile:81`) so the project's + own lint suite covers the new code. Check `dylint.toml:35-52` + `excluded_crates`: it currently names `whitaker`, and the meaning of that + entry changes once the package changes character. Under Constraint 6, any + new entry needs escalation. + +**Gate — the whole point of the milestone:** ```console -cargo check -p whitaker --bins --all-features 2>&1 | tee /tmp/spike-a.out -cargo check --workspace --all-targets --all-features 2>&1 | tee /tmp/spike-b.out +cargo package -p whitaker --no-verify ``` -Then add `use whitaker::greet;` and a call to it, and repeat, because a bin -that never references the library may not link it — which would make the first -result misleading: +must succeed. Then `make check-fmt && make typecheck && make lint && +make test NEXTEST_PROFILE=ci`, and the Dylint UI suite must be unchanged. + +Then answer the link question the first draft got wrong. `cargo check` does +**not** invoke the linker, so it cannot observe duplicate `std`/`core` +symbols. Use: ```console -cargo check -p whitaker --bins --all-features 2>&1 | tee /tmp/spike-c.out +cargo build --workspace --bins --all-features +cargo test -p whitaker --all-features --no-run ``` -Go/no-go: +under the same `RUSTFLAGS="-C prefer-dynamic -Z force-unstable-if-unmarked +-D warnings"` the test recipe uses. After the extraction the root package no +longer enables `rustc_private` at all, so this should be clean; if it is not, +stop and escalate. -- **Both succeed:** proceed to Stage B with the binary in the root package. -- **Either fails with duplicate `std`/`core` symbols:** delete the spike file, - record the transcript in `Surprises & discoveries`, set status `BLOCKED`, - and escalate with the `Risk R1` options. Do not proceed. +### Stage B — red tests and feature specifications -Delete the spike file before Stage B regardless of outcome. +No production behaviour yet. -### Stage B — red tests and feature specifications +1. `tests/features/whitaker_cli.feature` — reproduced in full under + `Artefacts and notes`. +2. `tests/behaviour_whitaker.rs` with a `CliWorld` fixture modelled on + `installer/tests/behaviour_cli/support.rs`. Named to avoid R4. +3. `tests/e2e_exit_codes.rs` (`EP-INV-EXIT`). +4. `tests/property_arg_parity.rs` (`EP-INV-PARITY`). +5. `src/cli/dispatch.rs` with the token enum, `classify`, and the + `#[cfg(kani)] mod verification` harnesses including the three reachability + harnesses (`EP-INV-DISPATCH`). +6. `verus/whitaker_cli_dispatch.rs`, witness lemmas first + (`EP-LEM-DISPATCH`). -No production behaviour yet. Write the failing specifications first. - -Create the crate skeleton `crates/whitaker_cli/` with `src/lib.rs` containing -only module declarations and doc comments, and add it to the workspace. Add -the four dependencies. Then write, in this order: - -1. `crates/whitaker_cli/tests/features/whitaker_cli.feature` — the Gherkin - specification, reproduced in full under `Artefacts and notes`. -2. `crates/whitaker_cli/tests/behaviour_cli.rs` with step definitions and a - `CliWorld` fixture modelled on `installer/tests/behaviour_cli/support.rs`. -3. `crates/whitaker_cli/tests/e2e_exit_codes.rs` (`EP-INV-EXIT`). -4. `crates/whitaker_cli/tests/property_arg_parity.rs` (`EP-INV-PARITY`). -5. `crates/whitaker_cli/src/domain/routing/kani.rs` (`EP-INV-ROUTE`), plus the - three reachability harnesses. -6. `verus/whitaker_artefact_naming.rs` (`EP-LEM-NAME`), starting with the - witness lemma. - -Validation for Stage B: every one of the above must **fail**, and the failure -must be the expected one. Record each red transcript. A test that fails -because a module does not exist is acceptable only for the compile-time -skeleton; the behavioural and property tests must reach a genuine assertion -failure once the skeleton compiles. +Every one must **fail**, for the expected reason. Record each red transcript. ### Stage C — implementation -Build the library, then the binary, then the packaging metadata. Each step -below names its file and what goes in it; see `Interfaces and dependencies` -for exact signatures. - -1. **Promote the binary-private orchestration.** In `installer/src/lib.rs`, - add `pub mod install_flow;` and move `installer/src/install_flow/` into the - library. Move the orchestration functions currently in - `installer/src/main.rs` (`run_install`, `run_dry`, - `try_fast_path_installation`, `finish_install`, - `finish_install_and_record_metrics`, `resolve_requested_crates`, - `generate_and_report_wrapper`, `ensure_whitaker_workspace`, - `resolve_toolchain`, `ensure_toolchain_installed`) into a new - `installer/src/orchestration/` module tree, each file under 400 lines. - Leave `staged_suite` binary-private (`Risk R5`); expose only the single - entry point the fast path needs, behind its existing gating. - `installer/src/main.rs` becomes a thin composition root calling the - library. **No behaviour changes.** Run `make test` here: every existing - `installer/tests/` test must pass **unmodified**. If any assertion needs - changing, that is a Constraint 1 breach — stop. - -2. **Define the domain and ports** in `crates/whitaker_cli/src/domain/` and - `crates/whitaker_cli/src/ports/`. The domain owns `Request`, `Outcome`, - `ExitCode`, the routing function, and the exit-code policy. It imports - nothing from `std::process`, `std::fs`, or `whitaker_installer`. This is - the dependency rule, and it is checkable: `crates/whitaker_cli/src/domain/` - must contain no `use whitaker_installer` and no `use std::{fs, process}`. - -3. **Define the driving adapter** in `crates/whitaker_cli/src/cli/`: the clap - `Parser`/`Subcommand`/`Args` structs for `whitaker`, `whitaker install`, - and `whitaker ls`, mirroring `installer/src/cli.rs` field for field, plus - the `ortho_config` localized-parse entry point. - -4. **Define the driven adapters** in `crates/whitaker_cli/src/adapters/`, - implementing the ports over `whitaker_installer`'s now-public - orchestration. - -5. **Add the composition root** at `src/main.rs` in the root package: build - the adapters, call `whitaker_cli::run`, map the outcome to a process exit - code. Target under 60 lines. Declare `[[bin]] name = "whitaker"` with - `autobins = false` in the root `Cargo.toml`, matching the convention at +1. **Promote the installer orchestration.** Add `pub mod install_flow;` to + `installer/src/lib.rs`, move `installer/src/install_flow/` into the + library, and move the ten `main.rs` orchestration functions into a new + `installer/src/orchestration/` tree, each file under 400 lines. + `installer/src/main.rs` becomes a thin composition root. + `try_fast_path_installation` calls + `staged_suite::try_test_staged_suite_installation` + (`installer/src/main.rs:87`), so the fast path and the staged-suite hook + move together; keep the hook behind its existing `#[cfg(debug_assertions)]` + and `test_support` gating and expose only the facade the fast path needs. + `installer/src/main.rs` also carries `#[cfg(test)] mod tests;` at `:402`; + those unit tests move with their subjects. That is relocation, not an + assertion change, and does not trip the behaviour-drift tolerance. + **No behaviour changes.** Validate with `make test NEXTEST_PROFILE=ci` — + not plain `make test`, which skips `behaviour_cli` and + `behaviour_toolchain`, the very binaries that would detect a dispatch + regression. + +2. **Wrapper generation becomes a parameter.** Give + `generate_and_report_wrapper` an argument naming which scripts to write. + `whitaker-installer` passes `{whitaker, whitaker-ls}`, preserving + Constraint 1 exactly. `whitaker install` passes `{whitaker-ls}` — it must + not overwrite the binary the user just invoked. + +3. **Build the CLI in the root package.** `src/cli/` holds the clap types; + `src/cli/dispatch.rs` the classifier; `src/cli/exit.rs` the exit policy; + `src/adapters/` the driven adapters over `whitaker_installer`. The root + `Cli` carries `command: Command` (not `Option`) plus the shared `-q`/`-v` + flags that `CLI-DESIGN` declares common options; `whitaker install` + **re-exports** `whitaker_installer::cli::InstallArgs` rather than mirroring + it field for field, so parity is true by construction and `EP-INV-PARITY` + guards the request mapping rather than struct shape. + +4. **Argument forwarding.** When `classify` returns `Forward`, resolve the + staged library directory the way the wrapper script does, set + `DYLINT_LIBRARY_PATH`, and run `cargo dylint` with the original arguments, + propagating its exit code. Keep this in one small adapter behind + `LintRunner`. + +5. **Composition root** at `src/main.rs`: construct adapters, parse via + `ortho_config`, dispatch, map to an exit code. Target under 60 lines. + Declare `[[bin]] name = "whitaker"` with `autobins = false`, matching `installer/Cargo.toml:11-27`. -6. **Remove `--exclude whitaker` from `TEST_EXCLUDES`** if and only if - `EP-M0` showed the package tests cleanly; otherwise leave it and note in - `Surprises & discoveries` that root-package tests remain excluded, with all - `whitaker_cli` tests living in the non-excluded crate (which is why they - were put there). - -7. **Add binstall metadata.** Parameterize - `installer/src/binstall_metadata.rs` over the package name rather than - hardcoding `"whitaker-installer"` (currently at lines 52 and 77), and add - the `[package.metadata.binstall]` block to the root `Cargo.toml` mirroring - `installer/Cargo.toml:95-101`, including the +6. **binstall metadata, additively.** Do **not** change the signatures of + `expand_pkg_url` or `expand_bin_dir` (`installer/src/binstall_metadata.rs:45`, + `:73`) — they are consumed by + `installer/tests/behaviour_installer_release.rs:155`, + `installer/tests/behaviour_binstall.rs:10-18`, + `installer/src/installer_packaging_tests.rs:274`, and their own doctests, + so narrowing them trips the interface tolerance. Add + `expand_pkg_url_for(package, version, target)` and + `expand_bin_dir_for(package, version, target)`, and reimplement the + existing two-argument forms as delegates. `load_cargo_toml` resolves the + manifest through `env!("CARGO_MANIFEST_DIR")`, baked to `installer/` at + compile time, so give it a `&Path` parameter for the root package's test to + use. Then add `[package.metadata.binstall]` to the root `Cargo.toml` + mirroring `installer/Cargo.toml:95-101`, including the `overrides.x86_64-pc-windows-msvc` entry with `pkg-fmt = "zip"`. - -Validation after each numbered step: `make check-fmt && make typecheck && -make lint && make test`, captured with `tee`.

- `src/lib.rs` records "duplicated `std`/`core` link errors ... during - all-features test runs". - Impact: drove the decision to place all testable CLI logic in - `crates/whitaker_cli` rather than in the root package, and created `EP-M0`. - -- Observation: `install_flow` and `staged_suite` are binary-private, so real - orchestration is unreachable from any other crate today. - Evidence: `installer/src/main.rs:7-8` declares `mod install_flow;` and - `mod staged_suite;`, neither appears in `installer/src/lib.rs`. - Impact: `CLI-REQ-LIB` is a genuine code move, not a re-export. - -- Observation: three distinct dependency-injection styles coexist in the - installer for the same concern. - Evidence: Table 1 above. - Impact: unifying them is deliberately out of scope; see `Decision log`. +- Observation: the root `whitaker` package cannot be published at all. + Evidence: `cargo package -p whitaker --no-verify --allow-dirty` fails with + "no matching package named `rustc_ast`"; the four `rustc_*` shim crates are + `publish = false`; the manifest has no `description`, `license`, or + `repository`. + Impact: decisive. Turned the driver-library extraction from a contingency + into `EP-M0`, the plan's precondition, and made a separate CLI crate + unnecessary. + +- Observation: the installer writes an executable named `whitaker` into the + user's binary directory, and a `cargo install`ed binary deterministically + shadows it. + Evidence: `installer/src/wrapper.rs:105`; `Makefile:9` prepends + `~/.cargo/bin` while `Makefile:6` appends `~/.local/bin`; `Makefile:99-139` + backs the script up around every test run; `Makefile:185` and `ci.yml:154` + invoke `whitaker --all`. + Impact: without forwarding, this change would break this repository's own + lint gate and every user's primary workflow, with no replacement until + 3.5.2.

Replaced with + `cargo build --bins` and `cargo test --no-run`. + +- Observation: both documented flag conflicts are enforced by clap, not by + repository-owned code. + Evidence: `conflicts_with` at `installer/src/cli.rs:108`, `:113`, `:131`. + Impact: a routing function can never receive a conflicting input, so the + first draft's Kani obligation was vacuous.

Putting logic there would make it - untestable under the repository's own gates. `CLI-DESIGN` requires the - _binary_ at the root package; it says nothing about where the library lives, - and "an internal library boundary" is precisely what a separate crate gives. - **Date/Author:** 2026-08-21, planning agent. - -- **Decision:** Adopt `ortho_config` in this plan for localized argument - parsing only (`LocalizedParse`, `NoOpLocalizer`, `is_display_request`), not - for configuration layering. - **Rationale:** The task brief asks for `ortho_config` with localized help. - `CLI-DESIGN` §Compatibility and migration sequences the configuration switch - as step 3, and `docs/roadmap.md` gives it its own item, 3.6.3, which - _requires_ 3.5.1. Wiring `whitaker.toml` discovery and the `dylint.toml` - bridge here would take work from 3.6.3 and half-activate a configuration - model this plan cannot finish. Taking the localization seam now satisfies - `CLI-REQ-L10N`, pays the dependency cost once, and shapes the argument types - so 3.6.3 adds `#[derive(OrthoConfig)]` and `load_and_merge()` without - restructuring. **This narrowing should be confirmed before implementation - begins.** - **Date/Author:** 2026-08-21, planning agent. - -- **Decision:** Do not unify the installer's three dependency-injection styles. - **Rationale:** It is a large refactor with its own risk profile and no - requirement in `CLI-DESIGN` driving it.

It is the currently shipping, - documented, published binary; `CLI-DESIGN` schedules its deprecation for a - named later release and `docs/roadmap.md` item 3.9.1 owns that work.

The extraction also lets + `--exclude whitaker` come out of `TEST_EXCLUDES`, which is what makes + `CARGO_BIN_EXE_whitaker` usable and the end-to-end obligation runnable; it + removes the `rustc_private` hazard permanently; and it stops `ortho_config` + propagating into eleven lint crates and fifty cross-compiled builds. Putting + the CLI in the binary's own package is also the universal Rust idiom — + `cargo`, `rustup`, `ruff`, `uv`, and `cargo-dylint` all do it, and + `cargo-dylint` solves the same contamination the same way. + Approved by the requester before drafting. Date/Author: 2026-08-21. + +- **D-2: Resolve the `whitaker` name collision by forwarding unrecognized + arguments to `cargo dylint`.** The ambiguity tolerance fired here: the design + document anticipates wrapper removal but assigns it to 3.9.3, while a root + binary shadows the wrapper immediately. Alternatives considered — removing + wrapper generation now, renaming the script, or pulling `whitaker check` + forward from 3.5.2 — each either strands existing users or is a large scope + increase. Forwarding costs roughly thirty lines, breaks nobody, and keeps + this repository's own `make lint` working.

Date/Author: 2026-08-21. + +- **D-3: Include `whitaker ls`, explicitly unstable.** The ambiguity tolerance + fired: `docs/roadmap.md:194` places `ls` at 3.8.1 ("Requires 3.6.2 and + 3.7.3") and `--json` at 3.8.2, while `CLI-DESIGN` §Public CLI surface + describes the end state. Both readings were presented.

Wiring `whitaker.toml` discovery here would + take work from 3.6.3 and half-activate a model this plan cannot finish. + Counter-argument recorded: with `NoOpLocalizer` there is no observable + localization benefit at this milestone, so the dependency's roughly 26 new + lock entries buy a one-line call-site difference.

Date/Author: 2026-08-21. ## Outcomes & retrospective To be completed at each milestone boundary and at completion. Before setting this plan to `COMPLETE`, reconcile every entry in `Surprises & discoveries` -against `docs/whitaker-cli-design.md`: update the design document where a -discovery contradicts it, raise an ADR where the architecture changed, and -record a purely mechanical difference here. Do not mark the plan `COMPLETE` -while any upstream change or deviation is unrecorded. +against `docs/whitaker-cli-design.md`. In particular, `CLI-REQ-FWD` has no +upstream source today and **must** be added to the design document, since +forwarding is a public behaviour carrying a compatibility commitment. Do not +mark the plan `COMPLETE` while any upstream change or deviation is unrecorded. ## Revision note -Initial draft, 2026-08-21. Covers roadmap item 3.5.1 only. Two points need -explicit confirmation before implementation begins: the `ortho_config` -narrowing recorded in `Decision log`, and the `EP-M0` go/no-go on placing the -binary in the root package. +**Revision 2, 2026-08-21.** Rewritten after a six-perspective design review. + +What changed, and why. The structural bet was wrong: `cargo package -p +whitaker` fails, so the root package cannot be published and the plan's stated +outcome was unreachable. The driver-library extraction, previously filed as a +contingency under a risk entry, is now `EP-M0` and the plan's precondition; +the separate `crates/whitaker_cli` crate it was designed to avoid is gone, +because the extraction makes the root package a normal, testable, publishable +CLI package. That also fixed three downstream defects: `CARGO_BIN_EXE_whitaker` +is now available to the end-to-end tests, the policy layer no longer imports +clap through a supposedly pure domain boundary, and `ortho_config` no longer +propagates into eleven lint crates. + +A collision the first draft missed entirely — the installer generates an +executable named `whitaker` that a `cargo install`ed binary deterministically +shadows, breaking `whitaker --all` and this repository's own `make lint` — is +now Constraint 2, requirement `CLI-REQ-FWD`, and the subject of both +verification obligations. + +Both original verification obligations were cut as vacuous: nothing ever +inverts an asset name, and clap rejects the flag conflicts before any +repository-owned routing code runs. They are replaced by argv-classification +totality and disjointness, bounded by Kani and closed unbounded by Verus. Exit +codes are settled at 0, 2, and 1 rather than left to the implementer. The +feasibility spike now uses `cargo build` rather than `cargo check`, which +cannot link and so could never have observed the failure it tested for. + +How it affects remaining work. `EP-M0` is new and is roughly 40 mechanical +files; the overall scope tolerance rose from 45 to 70 files to accommodate it. +`EP-M1` is unchanged. Three items still want a reviewer's eye: the +`googletest` and `pretty_assertions` inconsistency with the sibling plan for +7.3.1 (D-7), whether `ortho_config` earns its place at this milestone given +that `NoOpLocalizer` does not translate (D-6), and confirmation of +`is_display_request`'s exact signature before Stage B writes red tests against +it. From 6fe00a448fe12c54e24ffed644f405176deb8b0f Mon Sep 17 00:00:00 2001 From: leynos Date: Mon, 24 Aug 2026 04:01:25 +0200 Subject: [PATCH 04/13] Extract the Whitaker Dylint driver core Move compiler-private driver code and its tests into the non-publishable `whitaker_lint_core` package so the root package can become a normal, publishable CLI package. Migrate all in-tree lint consumers and templates to the internal package, and retain the moved tests through a dedicated feature-free core pass. This avoids Cargo feature-unification linkage failures without weakening the all-feature Dylint validation. --- Cargo.lock | 63 ++++++++-------- Cargo.toml | 40 ++-------- Makefile | 30 ++++----

The root package owns `whitaker`; its `src/cli/` modules own +parsing, routing, output policy, and process exit codes. `src/ports.rs` +declares installation, inventory, and Dylint-runner ports, and `src/adapters/` +supplies the production implementations. The CLI chooses whether and when an +operation runs. The installer library owns how installation and staging are +performed. + +The installer orchestration boundary is `whitaker_installer::orchestration`. +The root CLI calls `run_install_for_whitaker`, which uses the same installation +flow but does not write a `whitaker` wrapper. Inventory discovery is shared +through `whitaker_installer::list::collect_installed`; the root CLI and legacy +installer retain their own output and toolchain-display decisions. The +installer's existing public helpers remain source-compatible. + +For any invocation whose first non-global token is not `install`, `ls`, root +help, or root version, the root binary forwards all arguments after its own +executable name, in order, to `cargo dylint`. This includes `--` and the +arguments after it. The child exit status is preserved. This requirement is +`CLI-REQ-FWD`; it is derived from current user and Makefile workflows rather +than an upstream specification. It is deferred for removal until roadmap item +3.9.3, after `whitaker check` supersedes it. + +The root package depends on the installer library and root-only CLI +dependencies. The compiler-private driver remains in the non-publishable +`whitaker_lint_core` crate, so `ortho_config` and CLI dependencies do not +propagate into the cross-compiled lint crates. This boundary also makes the +future `whitaker check` lazy-repair decision belong to the CLI, while the +installer remains responsible for executing a requested repair. + +The root package carries cargo-binstall metadata. Publishing the crate reserves +the name `whitaker`, but GitHub release archives for that executable are not +published until roadmap item 3.5.3.

The remaining test failure is still isolated to + Dylint 6.0.4's parser not recognizing the managed rustc wrapper; permission + for a local dependency patch remains unanswered. No review or completion + claim is justified yet. + +- (2026-10-17T05:17Z) The user approved the increased plan-specific change + ceiling; D-12's 7,000-net-line cap remains unchanged. The latest `make fmt` + pass completed. The preceding `make lint` identified 43 Clippy violations in + the new tests. Reworked the root CLI BDD steps to return descriptive errors + instead of panicking, moved binstall metadata checks outside the test + boundary, and replaced property-test arithmetic flagged by workspace policy. + These changes still need current-candidate format, typecheck, test, and lint + validation. The last full test run still has one Dylint UI failure because + Dylint 6.0.4 does not parse the managed `build-limits-rustc` command prefix; + the separate request to authorize a local `dylint_testing` parser fix remains + unanswered. No wrapper bypass, test exclusion, CodeRabbit review, commit, + roadmap completion, or completion claim has been made. + +- (2026-10-17T05:51Z) Re-ran the four requested gates sequentially after the + test-lint repairs. `make check-fmt` passed and `make typecheck` passed. + `make test` ran for 1,193 seconds and again reported 1,677 passed, one + failed, and 12 not run; the sole failure is Dylint 6.0.4 not recognizing the + managed `build-limits-rustc` command for + `fail_unwrap_in_aliased_test_crate_non_companion`. `make lint` passed rustdoc + and Clippy, then found `installer/src/orchestration.rs` at 446 lines, over + the 400-line limit. Extracted dry-run handling and the legacy exit-code + adapter into `orchestration/dry_run.rs` and `orchestration/exit.rs`; the + public facade is now 396 lines and re-exports the same exit-code API. The + follow-up `make fmt` passed. The module-size correction and its full gate + rerun remain pending; the separate request for a local Dylint parser fix is + still unanswered. + +- (2026-10-17T06:03Z) The module split passes formatting and typecheck. The + full test gate still fails only in + `aliased_test_crate_non_companion_does_not_exempt_parent_function`: Dylint + 6.0.4 reports no captured `rustc` invocation for the managed + `build-limits-rustc` command, despite three retries. The latest lint run + reached Clippy and found the Rust module-file layout rule: a module with + sibling files must use `orchestration/mod.rs`, not `orchestration.rs`. The + facade has been moved to `installer/src/orchestration/mod.rs`; its 396-line + size is under the Dylint limit. Latest gate evidence is in + `/tmp/check-fmt-0c485c79-c21a-486e-b126-29c3ef23084f-3-5-1-root-whitaker-binary-6.out`, + `/tmp/test-0c485c79-c21a-486e-b126-29c3ef23084f-3-5-1-root-whitaker-binary-6.out`, + `/tmp/typecheck-0c485c79-c21a-486e-b126-29c3ef23084f-3-5-1-root-whitaker-binary-7.out`, + and + `/tmp/lint-0c485c79-c21a-486e-b126-29c3ef23084f-3-5-1-root-whitaker-binary-7.out`. + Moving the facade also changed the base for its explicit test-module path; + the first `make fmt` reported that missing path, so the attribute now points + to `../tests/mod.rs`. The subsequent `make fmt` passed, including Markdown + lint. Re-run all four gates against the renamed module before requesting any + review. The user has approved the 7,000-net-line plan ceiling; approval for + the narrowly scoped Dylint parser compatibility patch remains pending. + +- (2026-10-17T06:15Z) The renamed installer module now passes Clippy, but the + Whitaker stage of `make lint` reports that `src/cli/mod.rs` spans 426 lines + and that `run_command` contains two nested conditional clusters. The full + test run still fails only in the aliased-test-crate Dylint UI case: 1,677 + passed, one failed, 5 skipped, and 12 not run. Split the CLI into parsing and + execution modules behind the existing `whitaker::cli` facade, and simplify + install/list result handling. The `-8` logs are the current evidence; after + this source change, rerun the four full gates sequentially. The parser patch + request remains pending; no wrapper bypass or test exclusion is authorized. + +- (2026-10-17T06:16Z) Applied D-16: `src/cli/mod.rs` is now a ten-line public + facade, localized parsing and its unit tests live in `src/cli/parser.rs`, and + routing/execution live in `src/cli/runner.rs`. `run_command` delegates by + command and both handlers map a flattened `Result`, retaining the same public + re-exports and process outcomes. `make fmt` and `git diff --check` pass; the + module files are 10, 258, and 186 lines. The new source has not yet passed + the full gate sequence. The Dylint UI parser failure remains unchanged and + still requires the user's separate scope decision before a dependency patch + is attempted. + +- (2026-10-17T06:21Z) The `-9` sequential gate run passed formatting and + typecheck. The full test suite again had 1,677 passes and one failure: Dylint + 6.0.4 could not capture the managed `build-limits-rustc` invocation for the + aliased-test-crate fixture. Whitaker lint progressed beyond the earlier + module-size and complexity findings and reported `std::fs` use in three new + root-binary integration fixtures. Migrated their staging and executable + fixture writes to `cap_std::fs_utf8::Dir`, rooted at each temporary + directory; permissions are now set relative to that capability. The CLI + parser/runner split and these fixture changes pass `make fmt` and + `git diff --check`. A new complete gate run is required; the parser-patch + scope question remains unanswered, and no wrapper bypass or test exclusion is + authorized. + +- (2026-10-17T06:22Z) The first gate rerun after the capability migration + stopped `make test`, `make typecheck`, and `make lint` at compile time + because the root package had not declared `cap-std` as a dev-dependency. + Added the existing workspace dependency to the root package's + dev-dependencies; no package version or lockfile change is needed. Formatting + passed. Restart the four sequential gates before treating either the + filesystem lint remediation or the current candidate as validated. + +- (2026-10-17T06:27Z) After declaring the existing workspace `cap-std` + dependency as a root-package dev-dependency, the `-11` sequence passed + `make check-fmt`, `make typecheck`, and `make lint`, including Whitaker + Dylint. The full test suite again passed 1,677 tests and failed only + `aliased_test_crate_non_companion_does_not_exempt_parent_function` because + Dylint 6.0.4 did not recognize the managed rustc-wrapper command. The + capability-based fixture migration therefore compiles and clears the + filesystem lint findings. Supplementary `make nixie`, proof-runner `bash -n`, + and ShellCheck checks also passed. No dependency parser patch or wrapper + bypass has been made; the compatibility scope question is still unanswered. + +- (2026-10-17T06:30Z) Root packageability passed with + `cargo package -p whitaker --no-verify --allow-dirty`: Cargo packaged 166 + files (13.7 MiB, 3.9 MiB compressed). This confirms the root binary's package + manifest and binstall metadata are packageable, but does not reserve the + `whitaker` crates.io name or publish release assets.

Updated the test to + accept the standalone clause or the grouped form, and clarified the config + comment. The retry then passed `make check-fmt`, `make test`, + `make typecheck`, and `make lint` sequentially. Nextest passed 1,690/1,690 + main tests (five skipped); all 80 feature-free core tests and doctests + passed. The managed-wrapper Dylint parser patch is covered by the passing + test suite.

The + Whitaker suite then rejected ambient `std::fs` calls in the new adapter + tests.

This crate provides convenient access to the [`compiletest_rs`] package for testing [Dylint] +//! libraries. +//! +//! **Note: If your test has dependencies, you must use `ui_test_example` or `ui_test_examples`.** +//! See the [`question_mark_in_expression`] example in this repository. +//! +//! This crate provides the following three functions: +//! +//! - [`ui_test`] - test a library on all source files in a directory +//! - [`ui_test_example`] - test a library on one example target +//! - [`ui_test_examples`] - test a library on all example targets +//! +//!

In addition to the above three functions, [`ui::Test`] is a test "builder." Currently, the main +//! advantage of using `Test` over the above functions is that `Test` allows flags to be passed to +//! `rustc`.

In each case, the constructor's arguments are exactly those of the corresponding function. +//! +//! A `Test` instance has the following methods: +//! +//! - `dylint_toml` - set the `dylint.toml` file's contents (for testing [configurable libraries]) +//! - `rustc_flags` - pass flags to the compiler when running the test +//! - `run` - run the test +//! +//! # Updating `.stderr` files +//! +//!

N previous errors` line. So a correct `.stderr` file will typically contain one blank line at +//! the end. +//! +//! In general, it is not too hard to update a `.stderr` file by hand. However, the `compiletest_rs` +//! report should contain a line of the form `Actual stderr saved to PATH`. Copying `PATH` to your +//! `.stderr` file should update it completely. +//! +//!

Current base/head are `afb1e4ac1387aff8e51fa7bbeb62d94f0f6c8970` / - `6eadba3ce04172645745264bf9c6509d56d6ae85`. The PR author and all branch - contributors are `leynos` in `leynos/whitaker`, establishing the trusted - candidate basis independently of candidate instructions. M0 and M1 remain - complete; M2–M4 and roadmap 3.5.1 remain incomplete. The rebased `make test` - failure remains unresolved and no milestone review is requested until the - current candidate passes its deterministic gates. - -- (2026-10-15T17:17Z) Started EP-M2. Added the root command/application - boundary, pure routing and exit-policy modules, adapter ports, localized clap - parsing, and a production adapter for installer inventory and Dylint - forwarding. Added a public installer inventory collector by factoring the - existing scan path without changing its renderer. Root installs now select a - lister-only wrapper policy; the legacy installer keeps its two-script policy. - Added the first M2 property, BDD, exit-code, routing, and wrapper - preservation tests; these have not yet been validated. The first focused - compile caught a missing direct `camino` dependency and an obsolete import; - both were corrected. The follow-up compile was still queued when this entry - was written. - -- (2026-10-15T17:27Z) The queued `cargo check -p whitaker --all-targets` - completed successfully after 14m35s under shared compile admission. The - managed sccache service was unreachable, so compilation proceeded directly; - the initial run reported only an unused `Services` import in `src/main.rs`, - which has been removed. This check predates the latest property/BDD/proof - edits and is not current-candidate evidence. Tightened the parity test to - assert the specified 5% frequency for every option, added a fake-cargo BDD - forwarding scenario and dry-run staging assertion, and registered the planned - Kani/Verus proof runners. None of those changes has been validated yet. The - red-test transcripts were not captured before production code was present at - resumption; this deviation will be covered with explicit negative controls - for each proof/test obligation before acceptance. No M2 gate or CodeRabbit - review has been requested. - -- (2026-10-15T17:44Z) The refreshed all-target check exposed missing direct - root dev-dependencies for `rstest-bdd` and `whitaker_test_macros`, a missing - `clap::Parser` trait import in the parity test, and implicit capture syntax - unsupported by two `prop_assert_eq!` messages. Added the manifest edges and - explicit formatting arguments. The failure log is - `/tmp/check-whitaker-m2-current.out`; the corrected candidate has not yet - been checked. This confirms the BDD fixture remains local to the root package - and does not change production dependencies. - -- (2026-10-15T17:58Z) The retry compiled the new BDD dependency graph and all - root test targets, then found one ownership error in the parity test: the - first equality assertion moved `InstallArgs` before constructing the - `InstallRequest`. The assertion now compares a clone, preserving the value - for the request-level equality check. The retry log is - `/tmp/check-whitaker-m2-current-retry1.out`; another focused check is - pending. No production behaviour change was required. - -- (2026-10-15T18:05Z) `cargo check -p whitaker --all-targets` now passes on the - corrected source, including every root integration-test target, with no - diagnostics. It took 6m26s under the shared cache lock and compile-slot queue - while sccache remained unavailable. Current-candidate test execution, - format/typecheck/lint gates, Kani/Verus, packaging, smoke tests, and review - remain pending. The successful log is - `/tmp/check-whitaker-m2-current-retry2.out`. - -- (2026-10-15T18:15Z) The first root-package nextest run passed 26 of 33 tests, - including the exit/forwarding checks, JSON snapshot, and generated parity - property. Seven BDD cases failed before executing because their step fixture - parameter names did not match the scenario fixture. Renamed the fixture from - `cli_world` to the shared `world` name used by the step definitions. Failure - log: `/tmp/nextest-whitaker-m2-focused.out`. - -- (2026-10-15T18:21Z) `cargo nextest run -p whitaker` passes all 33 tests across - six binaries after the fixture correction. The seven root CLI BDD scenarios, - the `--all --version` forwarding check, JSON snapshot, and 4,096-set parity - property all pass. Log: `/tmp/nextest-whitaker-m2-fixture-fix.out`. This is - focused evidence; the full workspace CI-profile suite and remaining M2 gates - are still required. - -- (2026-10-15T18:27Z) Added the planned `OrthoConfig`/Clap derive-compatibility - spike as `tests/ortho_config_compat.rs` with `serde` limited to root dev - dependencies. Its test target compiled, but the first `nextest` invocation - filtered by target-file name and selected zero tests; no behaviour failure - occurred. Retry with an explicit test-name expression, then record the derive - result. Log: `/tmp/nextest-whitaker-ortho-config-spike.out`. - -- (2026-10-15T18:29Z) The explicit - `cargo nextest run -p whitaker ortho_config_derives_alongside_clap_parser` - retry passed its one selected test (33 unrelated tests skipped), confirming - the requested derive compatibility. The earlier filename filter selected no - tests and is not counted as evidence. CLI Kani and Verus checks and their - negative controls are the next bounded checks; full M2 gates and review - remain pending. - -- (2026-10-15T18:34Z) The focused Kani runner started, but its `cargo metadata` - child is waiting on the shared `/home/leynos/.cargo/.package-cache` lock; PID - 524311 holds the write lock for an unrelated offline build. Kani has not - reached its verifier and this is neither a pass nor a source failure. The - existing job remains in place; no parallel Cargo process or cache workaround - was started. Resume the proof check after the shared lock is released. - -- (2026-10-15T18:35Z) Read-only inspection found that the `cli` Verus group - had been registered for direct selection but its proof path was missing from - the `all` group's `printf` list because the preceding path lacked a shell - continuation. Added the continuation so `make verus` includes the new proof; - `bash -n scripts/run-verus.sh scripts/run-kani.sh` and `git diff --check` - pass. The focused Kani process remains blocked at Cargo metadata. - -- (2026-10-15T18:37Z) Rechecked the pending Kani metadata process. The original - cache-lock writer has exited and a different unrelated offline build (PID - 593239) now owns the package-cache write lock. The Kani process remains - alive and queued; no timeout or source failure has been reported. - -- (2026-10-15T18:40Z) Cargo released the shared package-cache lock. Kani has - begun compiling `whitaker` through its `cargo rustc --package whitaker --lib` - harness path. It is still compiling dependencies, so the empirical cost of - the crate-level graph has not yet been measured to completion. Let this first - run decide whether the planned pure-module siting is viable before - considering any structural deviation. - -- (2026-10-15T18:54Z) The Kani dependency build completed in 15m14s under the - shared compile queue. `verify_classify_is_total_and_disjoint` passed all 360 - generated checks (0 failed); Kani also noted unsupported constructs in the - larger library, but they were not reachable from this harness. The runner is - now checking the three intentional reachability counterexamples. The first - run confirms semantic viability but exposes a costly crate-level build; - consider a narrower shared production/proof boundary only if later Kani - invocations remain costly after this cache warm-up. - -- (2026-10-15T19:02Z) The `whitaker-cli` Kani group stopped on its first - reachability check. Kani reported the expected failure of the intentional - `assert!(false)` in `verify_subcommand_is_reachable`, but the runner then - returned failure because Kani 0.67.0 did not print the literal - `Counterexample:` marker required by `run_expected_counterexample`; it - emitted only the failed-check summary. No concrete input trace was captured, - and the other two reachability checks did not run. The totality harness - itself remains green; the group as a whole is not green. Full output is - `/tmp/kani-whitaker-cli-focused.out`. - -- (2026-10-15T19:02Z) Recalculated scope against live - `origin/harden-lint-config` at `afb1e4ac1387aff8e51fa7bbeb62d94f0f6c8970`. - The committed branch diff is 80 files and 2,436 net added lines. The current - uncommitted M2 candidate adds another 2,433 net lines (710 tracked net plus - 1,723 lines in 13 untracked files), for 4,869 net added lines. D-11 accepted - the existing file-count overrun only; it explicitly retained the 2,500-line - ceiling at that checkpoint. D-12 below records the user's later approval and - resumes implementation. No M2 milestone gates or CodeRabbit review have been - requested; roadmap item 3.5.1 remains unchecked. The Kani command also spent - 15m14s in dependency compilation; its harness verification itself took 4.73s - before the reachability attempt. D-12 later records that - compilation/admission is measured separately from verifier execution. - -- (2026-10-16T23:14Z) The user approved an increase to the remaining change-size - ceiling. D-12 sets an operational cap of 7,000 net added lines for this plan; - the candidate was 4,894 net lines at the latest recount, leaving 2,106 for M2 - completion, M3 packaging, and M4 documentation. The existing 80-file count is - already covered by D-11. The Kani tolerance counts verifier execution time, - while Cargo compilation and shared admission wait are recorded separately as - build cost; the measured 4.73-second positive proof is within budget. The - Kani runner still needs to recognize the verifier's reported failed - reachability assertion and run all three reachability harnesses before - acceptance. - -- (2026-10-15T19:05Z) `make fmt` formatted the plan checkpoint. The first - `make markdownlint` run caught an en-GB spelling issue in this new note; - after correcting it, the retry passed all spelling checks and linted 79 - Markdown files without errors. `make nixie` validated every diagram, and - `git diff --check` passed. Formatter changes to unrelated documentation were - restored. These documentation checks do not validate M2 product code or lift - the scope hold. - -- (2026-10-17T00:02Z) The Kani runner now validates Kani 0.67.0's actual output: - the positive totality harness passed 360 checks, and each of the three - reachability harnesses produced its named expected failure after a successful - concrete witness assertion. Verifier time was 3.345 seconds total; Cargo - build and shared-admission elapsed time was 2,633 seconds and remains outside - the verifier tolerance. Focused `bash -n` and ShellCheck checks passed for - both proof runners after expressing the empty `CDPATH` assignment as - `CDPATH=''`. The negative control that removes `Ls` routing, the Verus proof - and its overlap negative control, and full M2 gates remain outstanding. Kani - log: `/tmp/kani-whitaker-cli-runner-fix.out`; shell-check log: - `/tmp/shellcheck-0c485c79-c21a-486e-b126-29c3ef23084f-3-5-1-root-whitaker-binary.out`. - The latest worktree recount is +5,622/-674 (4,948 net added lines), leaving - 2,052 lines under D-12's 7,000-line ceiling. - -- (2026-10-17T00:06Z) Ran the planned Kani negative control by temporarily - routing `TokenTag::Ls` to `Forward`. `verify_classify_is_total_and_disjoint` - failed at the `Subcommand(Ls)` assertion in 5.206 seconds, so the proof - detects the intended regression. Kani's text output omitted its model - assignment; the minimal concrete witness is `raw = [1, 0, 0, 0, 0, 0]`, - `length = 1`, which the harness maps to `[Ls]`. Restored the production - classifier and confirmed its SHA-256 is identical to the pre-mutation value. - Log: `/tmp/kani-whitaker-cli-negative-control-20261017T000428Z-2446136.out`. - The Verus proof and overlap negative control, and full M2 gates, remain open. - -- (2026-10-17T00:19Z) The first CLI Verus invocation failed before verification - because this repository runs proof files as binary crates and requires the - empty `main()` used by every existing sidecar. Added that entry point and - reran the focused proof. `rust_verify` then ran CPU-bound for 650 seconds - without emitting a result; it was stopped after exceeding the ten-minute - Verus tolerance. No proof result is available. The output is - `/tmp/verus-cli-3-5-1-root-whitaker-binary-retry-20261017T000747Z.out`. - Further Verus runs are paused pending the user's decision on the explicit - tolerance exception. The positive Kani proof and its Ls negative control are - complete; the Verus proof and overlap negative control remain unresolved. - -- (2026-10-17T00:58Z) Implemented the root package's binstall metadata from the - installer's shared templates, including the Windows ZIP override, and added a - five-target disjoint-URL check. Kept existing two-argument expansion and - manifest-loader signatures intact by adding package-aware and explicit-path - helpers. The focused metadata test passed (1 passed, 0 skipped); Cargo - compilation took 14m51s in the shared queue and the test itself took 0.007s. - Log: - `/tmp/test-binstall-0c485c79-c21a-486e-b126-29c3ef23084f-3-5-1-root-whitaker-binary.out`. - A crates.io lookup returned 404 for `whitaker`; no publication or name - reservation has been attempted. M3 and the required reservation remain open. - The current target-to-worktree count is +5,829/-687 (5,142 net added lines), - leaving 1,858 lines under D-12's ceiling. - -- (2026-10-17T00:58Z) Simplified the CLI Verus model to recurse through one - enum-valued classifier instead of three independent recursive predicates. The - bounded retry was stopped after 481 seconds because the earlier 650-second - attempt had already exceeded the plan's cumulative ten-minute tolerance. No - proof result was produced. The user's latest approval increases only the - change-size ceiling; the separate Verus-runtime question remains unanswered. - No further Verus run or milestone review is authorized by that approval. - -- (2026-10-17T01:05Z) Started M4 documentation while the independent Verus - tolerance decision remains pending. Added ADR 005 for the root CLI boundary, - recorded the staged 3.5.1 command surface and `CLI-REQ-FWD` in the CLI - design, indexed the ADR, and updated the repository layout, developer - architecture notes, Dylint suite tree, and crate publishing guide. The user - guide remains deferred until the crates.io name reservation so it does not - instruct users to install an unpublished package. The 7,000-net-line ceiling - is the approved plan-specific limit; M2 proof acceptance, M3 reservation, - user-facing guidance, roadmap completion, and full candidate gates remain - open. - -- (2026-10-17T01:07Z) The help-path audit found that Clap's bare `help` - subcommand was classified as an unknown token and would therefore be - forwarded to `cargo dylint`, despite appearing in root help. Classified it as - a Whitaker display request and added an end-to-end exit/output regression in - `tests/e2e_exit_codes.rs`. This closes a routing gap without changing the - forwarding contract for `help` after `--` or after a Dylint option. The - focused test and full gates are pending the scrutineer. - -- (2026-10-17T01:10Z) Added Rustdoc examples for the new public root CLI, - installer inventory, package-metadata, wrapper-policy, and service-port APIs. - Confirmed the existing - `lister_only_generation_preserves_an_existing_whitaker_binary` unit test - directly protects the non-overwrite acceptance criterion. `make fmt` passed, - including all Markdown lint checks it invokes; its unrelated reflow of the - archived M0 debugging note was restored. The current worktree passes - `git diff --check`. The root help regression and final full candidate gates - remain pending scrutineer execution. - -- (2026-10-17T01:12Z) The user confirmed the increased change-size ceiling; - D-12's 7,000-net-line cap remains the operative limit. Counting tracked - worktree changes and untracked implementation files, the current target-to- - worktree delta is 5,689 net added lines. M2 command routing, adapter ports, - end-to-end coverage, M3 binstall metadata, and M4 internal documentation are - implemented but remain unvalidated as one candidate. The bare `help` - regression and public Rustdoc examples have since been added; `make fmt` and - `git diff --check` pass. The full deterministic gates, Verus approval/result, - negative-control run, crates.io name reservation, packaging/release checks, - and milestone reviews remain outstanding. - -- (2026-10-17T02:53Z) The final-gate run passed `make check-fmt`, then - `make test` terminated red after 4,145.720 seconds: 1,664 passed, five - failed, one timed out, and 20 were not run after fail-fast. The failures - followed nested Cargo lock/admission waits: two `rstest_helper` tests timed - out waiting for their live cross-process fixture lock, three Dylint UI tests - reported no captured `rustc` invocation, and `bumpy_road_function::ui::ui` - exhausted its three 10-minute attempts. Inspection found these - `rstest_helper` and two `no_unwrap_or_else_panic` cases were missing from the - existing `serial-dylint-ui` Nextest group. D-14 records a narrow filter - correction to serialize those nested-build tests; no product-code behaviour - was implicated by the captured errors. The test gate must be rerun after that - scheduling fix; typecheck, lint, Markdown, Mermaid, and CodeRabbit remain - unrun. - -- (2026-10-17T04:25Z) The rebased candidate passes `make check-fmt` and - `make typecheck`. The serialized full test run passed 1,677 cases before one - Dylint UI fixture failed to capture any `rustc` invocation; 12 tests were not - run after fail-fast. Inspection confirmed Dylint 6.0.4 only recognizes a - command whose first executable is named `rustc`, while this host's global - Cargo configuration inserts the managed `build-limits-rustc` wrapper. - Bypassing compiler admission or excluding this test would violate repository - policy. A request asks whether a minimal local patch to `dylint_testing` may - recognize the wrapper prefix; that scope decision is pending. The first - diagnostic lint run also found `finish_install` over the Clippy argument - limit. It now takes the existing `FinishInstallContext`, preserving behaviour - while grouping its inputs; the complete candidate gates must be rerun for - this source change. CodeRabbit, Markdown, Mermaid, and milestone acceptance - remain outstanding. - -- (2026-10-17T04:44Z) The fresh serialized test run confirmed that 1,677 of - 1,678 executed cases pass; the same Dylint UI fixture failed all retries - because `dylint_testing` could not recognize the globally configured - `build-limits-rustc` invocation. `make typecheck` passed. Diagnostic - `make lint` confirmed the installer finalization grouping removed its - original argument-count finding and exposed nine Clippy findings in the new - root CLI. Replaced redundant `continue`, collapsed equivalent help-token - arms, avoided variable shadowing and needless owned error arguments, and - grouped the stdout/stderr sinks into `CommandStreams` to keep the public - runner within the argument limit. These lint corrections have not yet been - revalidated. The user has not yet decided whether to authorize a narrow local - `dylint_testing` parser patch; no wrapper bypass or test exclusion is being - used. Full gates and CodeRabbit remain incomplete. - -- (2026-10-17T05:15Z) After the root CLI Clippy cleanup, a fresh check-format - pass and another 1,677-test pass reproduced the one Dylint wrapper-parser - failure; `make typecheck` passed. Rustdoc also passed. The subsequent Clippy - run found 43 policy violations in the new behavioral/property test files, - primarily `expect` calls in unmarked BDD steps, assertions in a - `Result`-returning test, and integer arithmetic forbidden by the workspace - lint policy. These are in-scope test quality findings and are being repaired - without lint suppressions. The remaining test failure is still isolated to - Dylint 6.0.4's parser not recognizing the managed rustc wrapper; permission - for a local dependency patch remains unanswered. No review or completion - claim is justified yet. - -- (2026-10-17T05:17Z) The user approved the increased plan-specific change - ceiling; D-12's 7,000-net-line cap remains unchanged. The latest `make fmt` - pass completed. The preceding `make lint` identified 43 Clippy violations in - the new tests. Reworked the root CLI BDD steps to return descriptive errors - instead of panicking, moved binstall metadata checks outside the test - boundary, and replaced property-test arithmetic flagged by workspace policy. - These changes still need current-candidate format, typecheck, test, and lint - validation. The last full test run still has one Dylint UI failure because - Dylint 6.0.4 does not parse the managed `build-limits-rustc` command prefix; - the separate request to authorize a local `dylint_testing` parser fix remains - unanswered. No wrapper bypass, test exclusion, CodeRabbit review, commit, - roadmap completion, or completion claim has been made. - -- (2026-10-17T05:51Z) Re-ran the four requested gates sequentially after the - test-lint repairs. `make check-fmt` passed and `make typecheck` passed. - `make test` ran for 1,193 seconds and again reported 1,677 passed, one - failed, and 12 not run; the sole failure is Dylint 6.0.4 not recognizing the - managed `build-limits-rustc` command for - `fail_unwrap_in_aliased_test_crate_non_companion`. `make lint` passed rustdoc - and Clippy, then found `installer/src/orchestration.rs` at 446 lines, over - the 400-line limit. Extracted dry-run handling and the legacy exit-code - adapter into `orchestration/dry_run.rs` and `orchestration/exit.rs`; the - public facade is now 396 lines and re-exports the same exit-code API. The - follow-up `make fmt` passed. The module-size correction and its full gate - rerun remain pending; the separate request for a local Dylint parser fix is - still unanswered. - -- (2026-10-17T06:03Z) The module split passes formatting and typecheck. The - full test gate still fails only in - `aliased_test_crate_non_companion_does_not_exempt_parent_function`: Dylint - 6.0.4 reports no captured `rustc` invocation for the managed - `build-limits-rustc` command, despite three retries. The latest lint run - reached Clippy and found the Rust module-file layout rule: a module with - sibling files must use `orchestration/mod.rs`, not `orchestration.rs`. The - facade has been moved to `installer/src/orchestration/mod.rs`; its 396-line - size is under the Dylint limit. Latest gate evidence is in - `/tmp/check-fmt-0c485c79-c21a-486e-b126-29c3ef23084f-3-5-1-root-whitaker-binary-6.out`, - `/tmp/test-0c485c79-c21a-486e-b126-29c3ef23084f-3-5-1-root-whitaker-binary-6.out`, - `/tmp/typecheck-0c485c79-c21a-486e-b126-29c3ef23084f-3-5-1-root-whitaker-binary-7.out`, - and - `/tmp/lint-0c485c79-c21a-486e-b126-29c3ef23084f-3-5-1-root-whitaker-binary-7.out`. - Moving the facade also changed the base for its explicit test-module path; - the first `make fmt` reported that missing path, so the attribute now points - to `../tests/mod.rs`. The subsequent `make fmt` passed, including Markdown - lint. Re-run all four gates against the renamed module before requesting any - review. The user has approved the 7,000-net-line plan ceiling; approval for - the narrowly scoped Dylint parser compatibility patch remains pending. - -- (2026-10-17T06:15Z) The renamed installer module now passes Clippy, but the - Whitaker stage of `make lint` reports that `src/cli/mod.rs` spans 426 lines - and that `run_command` contains two nested conditional clusters. The full - test run still fails only in the aliased-test-crate Dylint UI case: 1,677 - passed, one failed, 5 skipped, and 12 not run. Split the CLI into parsing and - execution modules behind the existing `whitaker::cli` facade, and simplify - install/list result handling. The `-8` logs are the current evidence; after - this source change, rerun the four full gates sequentially. The parser patch - request remains pending; no wrapper bypass or test exclusion is authorized. - -- (2026-10-17T06:16Z) Applied D-16: `src/cli/mod.rs` is now a ten-line public - facade, localized parsing and its unit tests live in `src/cli/parser.rs`, and - routing/execution live in `src/cli/runner.rs`. `run_command` delegates by - command and both handlers map a flattened `Result`, retaining the same public - re-exports and process outcomes. `make fmt` and `git diff --check` pass; the - module files are 10, 258, and 186 lines. The new source has not yet passed - the full gate sequence. The Dylint UI parser failure remains unchanged and - still requires the user's separate scope decision before a dependency patch - is attempted. - -- (2026-10-17T06:21Z) The `-9` sequential gate run passed formatting and - typecheck. The full test suite again had 1,677 passes and one failure: Dylint - 6.0.4 could not capture the managed `build-limits-rustc` invocation for the - aliased-test-crate fixture. Whitaker lint progressed beyond the earlier - module-size and complexity findings and reported `std::fs` use in three new - root-binary integration fixtures. Migrated their staging and executable - fixture writes to `cap_std::fs_utf8::Dir`, rooted at each temporary - directory; permissions are now set relative to that capability. The CLI - parser/runner split and these fixture changes pass `make fmt` and - `git diff --check`. A new complete gate run is required; the parser-patch - scope question remains unanswered, and no wrapper bypass or test exclusion is - authorized. - -- (2026-10-17T06:22Z) The first gate rerun after the capability migration - stopped `make test`, `make typecheck`, and `make lint` at compile time - because the root package had not declared `cap-std` as a dev-dependency. - Added the existing workspace dependency to the root package's - dev-dependencies; no package version or lockfile change is needed. Formatting - passed. Restart the four sequential gates before treating either the - filesystem lint remediation or the current candidate as validated. - -- (2026-10-17T06:27Z) After declaring the existing workspace `cap-std` - dependency as a root-package dev-dependency, the `-11` sequence passed - `make check-fmt`, `make typecheck`, and `make lint`, including Whitaker - Dylint. The full test suite again passed 1,677 tests and failed only - `aliased_test_crate_non_companion_does_not_exempt_parent_function` because - Dylint 6.0.4 did not recognize the managed rustc-wrapper command. The - capability-based fixture migration therefore compiles and clears the - filesystem lint findings. Supplementary `make nixie`, proof-runner `bash -n`, - and ShellCheck checks also passed. No dependency parser patch or wrapper - bypass has been made; the compatibility scope question is still unanswered. - -- (2026-10-17T06:30Z) Root packageability passed with - `cargo package -p whitaker --no-verify --allow-dirty`: Cargo packaged 166 - files (13.7 MiB, 3.9 MiB compressed).
