Summary
ValidationThe author reports that hosted CI passed on the latest reported head. The author also reports that formatting, lint, type-check, Markdown, and Nix checks passed. The reported test run was not fully green: 1,805 tests passed, 2 timed out, 5 were skipped, and 35 were not run after test failure. WalkthroughThe PR extracts installer tests into separate modules and adds coverage for downloader, dependency-installation and list-command behaviour. It documents the module-layout convention and changes test-module path resolution. ChangesInstaller test-module reorganisation

Full details: Docstring Coverage
-
Explanation
Docstring coverage is 80.77% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 52 functions across 9 files. (3 skipped: 3 unsupported.)
Full details: Testing (Overall)
-
Explanation
PASS — the pull request changes module layout, not product behaviour. The production diff only extracts existing test modules, renames
install_flow.rsandtoolchain.rstomod.rs, and removes the obsolete#[path]anchor. The extracted tests remain substantive:downloader_tests.rs:12-105checks size rejection, error mapping, destination placement, and checksum verification;policy_tests.rs:38-140checks source-fallback policy and executor call order;list_tests.rs:96-248checks output, discovery, toolchain detection, and target selection. The base and head test-name inventories preserve the existing test coverage, so no new behavioural path lacks a test.
Full details: User-Facing Documentation
-
Explanation
Pass the check. The pull request changes internal Rust module layout and test placement only. The rename-aware diff shows content-preserving module moves and extracted test files; no user-facing functionality or behaviour changes. The pull request adds the developer guide and ADR documentation for the internal layout, while
docs/users-guide.mdremains correctly unchanged.
Full details: Developer Documentation
-
Explanation
PASS: The PR documents the changed module architecture and test-placement convention in
docs/developers-guide.md:1407-1535. It documents the 400-line budget,mod.rsdirectory modules,#[path]test extraction, nested test modules, and the current enforcement limits. The new ADR records the decision, alternatives, rationale, and risks indocs/adr-006-directory-based-module-layout.md:1-156, anddocs/contents.md:99-100indexes it. The Rust diff is structural: it moves module roots and extracts existing tests, with no new public API, tooling requirement, or build requirement. No new execplan or roadmap item is introduced; the existing completedmodule_max_linesroadmap item remains checked off.
Full details: Module-Level Documentation
-
Explanation
All modules introduced or relocated by this PR have module-level
//!documentation. The extracted modules document their purpose and function indownloader_tests.rs:1,list_tests.rs:1,policy_tests.rs:1-6, andtests_repository.rs:1-5. The retained module roots document their purpose indownloader.rs:1,list.rs:1-4,deps/tests.rs:1,install_flow/mod.rs:1-4, andtoolchain/mod.rs:1-4. The install-flow documentation also explains its relationship to CLI orchestration. No module-level documentation failure is introduced.
Full details: Testing (Unit And Behavioural)
-
Explanation
The pull request preserves the existing tests while changing module layout. The extracted unit tests cover success paths, edge cases, errors, and invariants: downloader limits and destination placement (
downloader_tests.rs:11-109), list output and path-selection errors (list_tests.rs:96-248), and dependency-install fallback and refusal paths (policy_tests.rs:37-141,tests_repository.rs:42-169). Existing downloader behavioural boundary tests still exercise the local HTTP boundary, checksum failures, oversized sidecars, and partial-file cleanup (downloader_boundary_tests.rs:89-218). The production changes are file moves and module declarations, so they do not introduce a new external workflow that requires an additional end-to-end test.
Full details: Testing (Property / Proof)
-
Explanation
Keep the current example-based tests. The diff is a module-layout refactor:
install_flow.rsandtoolchain.rsare renames, and production files only gain test-module declarations (downloader.rs:289-291,list.rs:177-179,deps/tests.rs:294-298). The added tests cover concrete downloader, list, and dependency-install cases. The PR introduces no invariant over a broad input or state range, and it introduces no lemma or proof assumption. A property test or exhaustive proof is therefore not required by this check.
Full details: Testing (Compile-Time / Ui)
-
Explanation
The pull request introduces no new compile-time API or diagnostic behaviour. It relocates inline tests and changes module-file resolution only:
downloader.rsandlist.rsdeclare sibling test files,deps/tests.rsdeclares two sibling test modules, andinstall_flow/mod.rsuses the default directory-module declaration. The moved tests retain focused assertions for list output, installer messages, and error behaviour. No new text or structured output is introduced, so snapshot tests are not required. The repository already has a trybuild harness for its existing compile-fail contract ininstaller/tests/ui.rs.
Full details: Unit Architecture
-
Explanation
Pass this check. The reviewed range only relocates existing tests, renames two module files, updates module declarations, and adds documentation. Product code remains unchanged apart from removing the obsolete
#[path]anchor ininstaller/src/install_flow/mod.rs. The new declarations remain test-only indownloader.rs:289-291,list.rs:177-179, andinstall_flow/mod.rs:364-368; extracted tests retain explicit seams such asWriteand mocked executors. No query, command, fallible-operation, dependency-injection, or side-effect boundary becomes less visible.
Full details: Domain Architecture
-
Explanation
Pass. Keep the domain boundary unchanged. The diff only extracts test modules, adds module declarations, renames
install_flow.rsandtoolchain.rstomod.rs, and updates documentation. The production implementations remain unchanged; the new declarations only load tests, for exampledownloader.rs:289-291,list.rs:177-179, anddeps/tests.rs:294-298. No change introduces HTTP, SQL, filesystem, transport, persistence, or vendor concerns into domain logic.
Full details: Observability
-
Explanation
PASS — this pull request changes module layout, test placement, and documentation only. The diff shows test bodies moved behind
#[cfg(test)]and#[path]declarations, plus two file-to-mod.rsrenames. Theinstall_flowrename removes one stale test-module path attribute; production code is otherwise content-preserved. No new or altered production operational behaviour, logging, metrics, tracing, or alerts requires observability changes.

Three test timeouts in whitaker_clones_core::build_script_integration
were investigated rather than assumed benign, and shown to be host
contention: the same four tests pass unaided in 83–116 s given an
adequate budget. That test spawns a nested cargo build, so it costs
what a build costs, but it currently has no [[profile.ci.overrides]]
entry in .config/nextest.toml despite the comment there citing exactly
that pattern for build-cost tests. I have not changed that file,
since other work is in flight against it — flagging it as an
observation.
make lint initially failed with os error 11 (EAGAIN) at compiler
spawn. That was diagnosed to the shared service cgroup's pid ceiling
(pids.max 8192, ~92% consumed by concurrent agents on this host), not
to this change or to build admission — the compiler process was never
executed, so the token pool never had a chance to queue it. Bounding
cargo's jobs to 4, which matches the admission pool's capacity, let the
full unrestricted run complete cleanly.
Hosted CI
refs/pull/364/merge is still frozen at 7f6dcab (built 2026-08-29
from the pre-rebase head), so the push did not produce a
pull_request run — the merge ref was never recomputed. CI was
therefore started explicitly on the new head:
https://github.com/leynos/whitaker/actions/runs/38280686373
That run is on e4959b248364. Reporting this plainly rather than
implying the push triggered it.
Reviews
CodeScene has already re-assessed the new head and passed — a fresh
review bound to e4959b248364, "6 Quality Gates Passed", not a carry
over. Gecko Security also re-ran clean on the new head. The earlier
CodeRabbit and Sourcery reviews are bound to b5e49282bea1 and are
superseded.

Move the remaining self-named module files to mod.rs form (install_flow, toolchain) and extract oversized in-src test modules into sibling files (list, workspace, downloader, the non-UTF-8 boundary tests, the dependency-binary fakes, and the deps repository tests), each wired with the repo's `#[cfg(test)] #[path]` convention and opening with an explanatory `//!` line. The moves are content-preserving: extracted test bodies are this tree's code verbatim; only the module structure changes. This keeps every module inside the 400-line budget the lint configuration later in this stack will enforce, without entangling the structural review with lint fixes.
The directory-module rebase rebuilt `downloader_tests.rs` by dedenting the parent's inline `mod tests` body. rustfmt had laid that body out at the deeper inline indentation, so a call whose argument list crossed the width limit kept its break at the old indent column. After dedenting, the reflow no longer matched rustfmt's choice and `make check-fmt` reported a diff at the `destination_dir` binding. Rejoin that line so the extraction is formatting-neutral. The edit moves only whitespace: the token stream is identical, with the same 527 tokens in the same order, and the call is applied to the same arguments and bound to the same name. Co-Authored-By: Claude Code <noreply@anthropic.com>
The restack onto the advanced parent left `installer/src/deps/tests.rs` at 467 lines. The parent had grown the file to 561 while my extraction split it at the point that was correct for the older content, and the two changes overlapped: the repository-install tests ended up declared in both files. Split the file along its two independent concerns instead. `policy_tests.rs` owns the source-fallback refusal tests and the two private helpers only they use; `tests_repository.rs` owns the repository-installer tests. `tests.rs` keeps the shared prologue and declares both children, so the private helpers stay reachable through `super::*`. Every module is now inside the repository's 400-line limit: tests.rs is 294 lines, policy_tests.rs 140, tests_repository.rs 169. Co-Authored-By: Claude Code <noreply@anthropic.com>
CodeRabbit's pre-merge "Developer Documentation" check failed on this branch: the change renames two installer modules to `mod.rs` form and extracts inline test modules into sibling files, and none of those conventions was written down. Add a `## Module layout and test placement` section to the developers' guide covering the 400-line budget and its rationale, the directory-module `mod.rs` convention, the three shapes of extracted test module, and where the budget is enforced. Every claim is taken from the tree rather than asserted: 46 tracked `mod.rs` files outside `vendor/` and 65 files carrying a `#[path = "` anchor show the convention is repository-wide, and the threshold is the `module_max_lines` dylint lint's 400-line default, not a Clippy built-in. Record the one variation as well. `installer/src/deps/tests.rs` is itself declared `#[cfg(test)] mod tests;`, so its children omit the attribute and take their names from the `#[path]` files instead. Co-Authored-By: Claude Code <noreply@anthropic.com>
Add ADR 006, which records the directory-based module layout the previous commit only described: mod.rs-rooted directory modules, and extraction of an oversized inline test module into a sibling file wired with `#[cfg(test)] #[path = "..."] mod ...;`. Two alternatives are recorded as rejected, including the self-named `name.rs` next to `name/` form, which no path in this repository uses. CodeRabbit's Developer Documentation pre-merge row required the structural decision to be recorded in a design document or an ADR. The requirement was previously unreadable because the summary table truncates the cell; the same row appears in full in the comment's per-check details block. ADRs 001-005 were registered in docs/contents.md, so 006 is added there too. Correct an unsupported claim in docs/developers-guide.md. The section added in the previous commit said the 400-line budget "is enforced mechanically by module_max_lines" and that the lint is "wired in through the workspace's lint configuration". Neither holds. `make lint` is a cargo doc pass plus cargo clippy, with no dylint step; the only dylint sub-command in the repository is a `dylint list` in publish-check that enumerates built libraries and lints nothing; the root dylint.toml configures no_std_fs_operations alone; and Cargo.toml has no [workspace.lints] table. The budget is held by review until the self-linting gate lands. The section is retitled "Where the budget is checked" and links ADR 006. Removing the stale [module_max_lines] TOML block from a file that doc_extraction reads is safe: find_block_containing returns the first match, which comes from docs/users-guide.md. Docs-only change; gated with check-fmt, markdownlint, nixie, lint, typecheck, and the behaviour_docs integration test, which owns the doc_extraction module tests that read these files. Co-Authored-By: Claude Code <noreply@anthropic.com>
Fix an error introduced in 0d9d377. The developers' guide said "there is no [workspace.lints] table in Cargo.toml". That is false: Cargo.toml:185 declares [workspace.lints.rust] and Cargo.toml:191 declares [workspace.lints.rustdoc], and two manifests inherit them through `[lints] workspace = true`. The error came from grepping for the literal string `[workspace.lints]` including the closing bracket, which matches only an exactly-empty table name and so cannot match a subtable. The conclusion was right for the wrong reason: neither table names module_max_lines, so the budget is still not enforced. The paragraph now states the tables exist, that they configure rustc and rustdoc lints, and that neither names module_max_lines. It also drops a second over-claim in the same sentence: ci.yml:302 does restore the dylint host tools, so saying CI's "one use" of them is the publish-check step conflated restoring the tools with invoking them. They are restored for that step, whose single dylint invocation is the `dylint list --no-metadata --no-build` that enumerates built libraries and lints nothing. Docs-only change; gated with check-fmt, markdownlint, nixie, lint and typecheck, and verified against the tree rather than restated. Co-Authored-By: Claude Code <noreply@anthropic.com>
Fix errors I introduced in 2991148 and 0d9d377. Both were asserted without being checked, and both were repeated in the developers' guide and ADR 006, so the same mistake shipped twice. 1. "attribute-free form, drawing their names from the #[path] files" described deps/tests.rs's children as attribute-free while naming #[path] as the source of their names. That is self-contradictory: #[path] is the attribute that names them. At installer/src/deps/tests.rs:291-295 the children do carry #[path]; the attribute they lack is #[cfg(test)], because deps/mod.rs:548 already gates the whole file. The #[path] is load-bearing, since no deps/tests/ directory exists for a bare `mod` to resolve into. 2. "The repository does not use this form anywhere" was false. Two production modules reach a child through a same-named directory: installer/src/cli.rs:182 resolves `mod source_policy;` to cli/source_policy.rs, and crates/conditional_max_n_branches/src/driver.rs:24 resolves `mod numeric;` to driver/numeric.rs. Resolution is unambiguous -- neither installer/src/source_policy.rs nor crates/conditional_max_n_branches/src/numeric.rs exists. Both were already present at the base commit, so this PR did not introduce them. The supporting figures verified exactly and the Option B rejection still stands; only the stated reason was wrong. The documents now name the two outliers explicitly as things not to copy, rather than denying them. Docs-only change; gated with check-fmt, markdownlint, nixie, lint, typecheck and the behaviour_docs target, whose DOC_PATHS pins docs/developers-guide.md as a test input. Co-Authored-By: Claude Code <noreply@anthropic.com>
`#[path]` resolves relative to the directory containing the declaring file, so a file module and a directory module resolve the same attribute to different paths. After rebasing onto f3a457b, the base's anchor survived the rename of `installer/src/install_flow.rs` to `installer/src/install_flow/mod.rs`, doubling its leading segment to `install_flow/install_flow/...`: failed to resolve mod `dependency_check_tests`: .../install_flow/install_flow/dependency_check_tests.rs does not exist `check-fmt` caught this because rustfmt resolves every `mod` declaration, whereas a build without `--all-targets` does not reach it. Delete the attribute rather than retarget it. Inside a directory module a bare `mod dependency_check_tests;` resolves to the identical file, so the anchor carried no information; the sibling `mod tests;` above it is already bare, and the convention recorded in ADR 006 confines the attribute to the file-module case. Deleting it also removes a manual anchor that ADR 006 already names as a staleness risk, and returns the tree-wide anchor count to the 65 both the ADR and the developers' guide already state. Correct two claims this rebase invalidated: the guide no longer asserts that `install_flow/mod.rs` ends with `mod tests;`, and ADR 006 now records the module-form hazard alongside its other `#[path]` risks. A sweep of all 81 `#[path]` anchors across 542 tracked `.rs` files finds every one resolving to an existing file, so the hazard was confined to this case.

Sorry, something went wrong.
The module layout documents claimed that `#[path]` holds a module's path still, and that relying on the default location would break `super::` inside a renamed test module. Compile probes show both claims are wrong. `mod tests;` fixes the module name, and with it the path `crate::list::tests`; `#[path]` selects the file that backs it. A bare `mod tests;` already yields that name and path, so the attribute creates neither. What the attribute supplies is the placement: left alone, a bare `mod tests;` in `list.rs` resolves to `list/tests.rs`, and naming the declaration after the file resolves to `list/list_tests.rs`. Neither reaches a sibling, so only the attribute puts the file beside `list.rs` while keeping the module named `tests`. Renaming the module would not break `super::` on its own, because the module stays a child of `list`. Only absolute paths such as `crate::list::tests::…` and `cargo test` filters naming `tests` break. Correct all four mirrors of the claim: the decision outcome and the architectural rationale in ADR 006, and the sibling-test-modules lead-in and preferred-form paragraph in the developers' guide. The decision itself is unchanged; only its stated justification is. Co-Authored-By: Claude Code <noreply@anthropic.com>

Summary
This branch adopts directory-based module structure across the installer: two
self-named module files move to
mod.rsform, and oversized in-src test modulesare extracted into sibling files wired with the repository's
#[cfg(test)] #[path = "..."] mod ...;convention. Every move iscontent-preserving — extracted test bodies are this tree's code verbatim, so the
review is purely structural. Each module this branch touches is now inside the
400-line budget, without mixing lint fixes into the structural diff.
Third PR in the lint-hardening stack, based on
harden-lint-spelling.Review walkthrough
installer/src/install_flow/mod.rsis
install_flow.rswith exactly one line deleted — the#[path]anchordescribed under "One repair this rebase required" below.
installer/src/toolchain/mod.rsis byte-identical to its pre-move path; both resolve to blob
9615cd5bf282158aa44e0243fae77da522b8c3c4.installer/src/list.rsshows the extraction pattern: the inline
mod testsbecomes#[cfg(test)] #[path = "list_tests.rs"] mod tests;, andinstaller/src/list_tests.rsopens with its
//!purpose line.deps/tests.rs(split intopolicy_tests.rsandtests_repository.rs) anddependency_binaries/install/downloader.rs(intodownloader_tests.rs).This PR moves test modules only.
installer/src/workspace_tests.rs,installer/src/dependency_binaries/install/downloader_boundary_tests.rs(the#[cfg(unix)]non-UTF-8 boundary tests), and the dependency-binary fakes alreadylive in sibling files at the base and are not touched here.
One repair this rebase required
#[path]resolves relative to the directory containing the declaring file, soa file module and a directory module resolve the same attribute to different
paths. The base carried
#[path = "install_flow/dependency_check_tests.rs"]ininstaller/src/install_flow.rs; after the rename toinstall_flow/mod.rsthatanchor doubled its leading segment and resolved to
install_flow/install_flow/dependency_check_tests.rs, which does not exist.7ec1640deletes the attribute rather than retargeting it. Inside a directorymodule a bare
mod dependency_check_tests;resolves to the identical file, sothe anchor carried no information; the sibling
mod tests;above it is alreadybare, and ADR 006 now confines the attribute to the file-module case.
Worth recording where this was caught:
make check-fmtfound it, because rustfmtresolves every
moddeclaration, whereas a build without--all-targetsneverreaches a
#[cfg(test)]module.make typecheckcovers it too(
--workspace --all-targets --all-features).Validation

Why
make testis not green heremake testis recorded as not green rather than omitted, and the reason ishost contention, not a defect in this branch. Four independent checks say so:
PR does not modify, and their blobs are identical to the base.
whitaker_clones_coreorno_std_fs_operationsis changed.c3b43dd3,crate_builds_without_dylint_driver_featurepassed at 191.906s in one runand timed out at 300.003s in another. Identical commits, opposite
outcomes, so the variable is the host.
build_script_accepts_an_exact_workspace_parser_pinexhausted the 30-minute
binary(build_script_integration)override — not the300s base — while
build-limits-statusshowed the compile pool saturated anddozens of cargo/rustc processes from other repositories queued.
The run's final line is
1807/1842 tests run: 1805 passed, 2 timed out, 5 skipped, then35/1842 tests were not run due to test failure. There werezero assertion-level failures and zero panics. Both victims are tests that
spawn a nested
cargobuild, which is precisely the class whose wall timetracks compiler admission rather than test logic.
Quantified against the hosted runner, which uses the same 300s base and the
same configuration: the same test blob passes in 0.815s on a hosted runner,
and the whole CI suite completes in ~17 minutes there against this host's
85-minute budget. CI is not more generous; it is uncontended.
This is deliberately not worked around. Raising the timeout, editing
.config/nextest.toml, or touching those test files would be metric gaming, andthe timeout policy belongs to the later lint-configuration layer rather than to
this structural PR.
.config/nextest.tomland both test files are byte-identicalto the base; the gap is real and pre-existing, and the hosted CI run above is the
arbiter for this candidate.
Base advance since publication
The base branch advanced by one commit after this branch was published:
01f4b86"Split source-policy cloning fromClone::clone", which touchesinstaller/src/error.rsalone (+20 −8).It does not interact with this branch, and the checks above establish that
directly. It touches one file this PR never changes;
merge-treereproducesGitHub's merge ref tree exactly with no conflict; and the resulting merge is a
clean union in which the base's refactor survives verbatim. No restack was
required, and no branch commit was replayed.
Documentation
docs/developers-guide.mdgains the module-layout conventions, themod.rsrule, the sibling-test-module convention, and test-module placementrules.
docs/adr-006-directory-based-module-layout.mdrecords the structuraldecision, with three options considered and the two rejected ones explained.
The guide and the ADR state plainly that the 400-line budget is not currently
enforced automatically against this repository's own source — it is a
review-held convention.
make lintiscargo docpluscargo clippy; there isno
dylint runtarget; the rootdylint.tomlconfigures[no_std_fs_operations]alone; and the
[workspace.lints.rust]and[workspace.lints.rustdoc]tables inCargo.tomldo not loadmodule_max_lines. The stack ends with a Whitakerself-linting layer that has not landed, and these documents no longer describe
that layer's intended end state as the current one.
docs/developers-guide.mdis a test input:installer/tests/doc_extraction/extraction.rsextracts its fencedtomlblocksand
installer/tests/behaviour_docs.rsasserts on them. That target passes inthe run above.
Notes
deps/install.rs→install_repository.rssplit isdeliberately not here — it is lint-fix-driven (complexity extraction) and lands
with the installer lint fixes PR.
