Install Merman with cargo-binstall - #412
Conversation
Reviewer's GuideThis PR updates the install-nixie composite GitHub Action to conditionally install cargo-binstall via a pinned cargo-bins/cargo-binstall action only when it is not already present, and adjusts the corresponding tests to reflect the new multi-step workflow while preserving the existing Nixie/Merman install contract.

tests/test_makefile_typecheck.py:50,88-102now assertsuv run ty check --python .venvfor both commands and preserves all path arguments. The Install Nixie tests execute the action's Bash fragments with isolated stubs and cover probing, pinned setup, exact versions, binary-only installation, cache repair, target mapping, token isolation, failure propagation, prerequisites, Nixie reconciliation, and PATH export (.github/actions/install-nixie/tests/test_action.py:53-627). The Rust reference tests validate the pinned revision and both cache-pruning controls (.github/actions/rust-build-release/tests/test_setup_rust_reference.py:246-306).

Full details: Developer Documentation
-
Explanation
Accept the documentation update. The reviewed range adds accepted ADR 0010, which records the cargo-binstall replacement, binary-only policy, exact version and target selection, cache checks, unsigned artefact policy, token scope, and trust boundary (
docs/adr/0010-merman-binary-installation-trust.md:1-50). The developer's guide lists the ADR and documents the implementation and maintenance rules (docs/developers-guide.md:28-38,2996-3054). The action README and users' guide describe the same installation, verification, authentication, and trust decisions (.github/actions/install-nixie/README.md:62-117,docs/users-guide.md:1576-1666). The guide also documents the changed.venvTy resolution and uv-cache controls (docs/developers-guide.md:2845-2853,3286-3293). No roadmap item or new execplan changed in the reviewed range. Prior failure addressed: Added and accepted ADR 0010, linked it in the developer guide's ADR index, and synchronized the developer, action, and users' documentation with the cargo-binstall trust and installation decision.
Full details: Module-Level Documentation
-
Explanation
All five changed Python modules carry module-level docstrings at line 1. The new install-nixie support module documents its fixtures, utility, and relationship to
test_action.py(._github/actions/install-nixie/tests/_install_nixie_test_support.py:1-8). The other changed modules document their testing purpose and related component:test_action.py(line 1),test_setup_rust_reference.py(lines 1-7),tests/test_makefile_typecheck.py(line 1), andworkflow_scripts/tests/skylos_contract_support.py(lines 1-15). The remaining changed files are configuration or documentation files, not modules requiring Python module docstrings.
Full details: Testing (Property / Proof)
-
Explanation
The prior property-test concern is addressed. The changed test suite now uses Hypothesis strategies for valid three-component numeric Merman versions and invalid forms, including leading zeroes, prefixes, suffixes, missing components and separators. Each generated value runs through the action harness. Valid values must reach
cargo binstallunchanged at.github/actions/install-nixie/tests/test_action.py:358-373; invalid values must fail before installation and PATH export at:375-390. The existing parameterized boundary cases remain at:334-356and:393-410. Hypothesis is declared inpyproject.toml:31-42. No explicit property-testing failure condition remains. Prior failure addressed: Added Hypothesis strategies and generated valid/invalid Merman-version tests in test_action.py:34-50 and :358-390. The tests assert unchanged forwarding for valid values and no install or PATH export for invalid values.
Full details: Testing (Compile-Time / Ui)
-
Explanation
Treat the check as passed. The reviewed diff contains no Rust or TypeScript files, so no trybuild or language-specific compile-time test applies. The changed GitHub Action is not UI output; its Python tests use focused semantic assertions for commands, exit codes, error text, token scope, cache reconciliation, and PATH contents (for example, head test_action.py lines 123-144, 270-287, and 453-466). No snapshot-based output contract is introduced or required.
Full details: Domain Architecture
-
Explanation
PASS — This pull request changes GitHub Actions and developer tooling, not core domain code. The repository identifies itself as a GitHub Actions collection (README.md:1-7, 8-40). The Merman version checks, runner-target mapping, Cargo/uv calls, cache handling, PATH export, and token scoping remain in the composite infrastructure adapter (.github/actions/install-nixie/action.yml:22-186). The added Python module is test-only support and explicitly states that production code must not import it (.github/actions/install-nixie/tests/_install_nixie_test_support.py:1-8). The Makefile and Rust action changes also concern type-check and cache infrastructure. No changed file introduces a domain model or makes domain logic depend on transport, persistence, filesystem, environment, or vendor details.
Full details: Description check
-
Explanation
The description directly matches the changeset. It explains the cargo-binstall migration, cache reconciliation, verification, platform handling, Ty configuration, tests, documentation, and validation results.
-
Full details: Testing (Unit And Behavioural)
-
Explanation
The PR adds meaningful unit and stub-based behavioural coverage, but it does not add the required end-to-end coverage for the changed installation workflow. The tests extract shell fragments from
action.yml(.github/actions/install-nixie/tests/_install_nixie_test_support.py:91-102) and execute them with deterministic Cargo,cargo-binstall,uv, Merman, and path stubs (.github/actions/install-nixie/tests/_install_nixie_test_support.py:132-226, 290-319). They do not invoke the composite action on a real runner or exercise the real release lookup, prebuilt Merman binary, Nixie installation, PATH execution, or cache reuse. The authoritative PR diff changes no workflow file. The existing CI workflow still installs Merman withinstall-tooland Nixie with directuv tool install(.github/workflows/ci.yml:105-117), so it does not exercise.github/actions/install-nixie.Resolution
Add a runner-backed end-to-end workflow for
install-nixiewithcontents: readpermission and the supported runner matrix. Verify the real Merman and Nixie executables, requested versions, PATH execution, and target selection. Add a second invocation or cache-restore job to verify real cache reuse. Retain the stub-based tests for deterministic error and token-isolation coverage.
Full details: Unit Architecture
-
Explanation
Fail. The pull request adds
Check cargo-binstall availabilityat.github/actions/install-nixie/action.yml:22-30. The query-labelled step runscargo binstall -Vand writesinstalled=trueorinstalled=falseto${GITHUB_OUTPUT}. The next command reads that published state at line 32. This query therefore mutates externally visible GitHub Actions state. The changed tests at.github/actions/install-nixie/tests/test_action.py:162-187and190-246explicitly require and exercise this boundary. The base action had no such step, so the failure is introduced by this pull request.Resolution
Remove the state-mutating query boundary. Make the pinned
cargo-bins/cargo-binstallsetup unconditional, or move prerequisite detection and installation into one explicitly named command that owns the side-effect. Keep availability detection and state publication out of a read-labelled query path, then update the behavioural tests to verify the revised command boundary.
Full details: User-Facing Documentation
-
Explanation
Add an Install Nixie migration document before release. The action introduces a Cargo and
cargo-binstallprerequisite, pinned bootstrap, prebuilt-only Merman installation, new version and target rules, cache reconciliation, scoped token use, and WindowsGITHUB_PATHhandling (.github/actions/install-nixie/action.yml:22-161). The users' guide documents current behaviour (docs/users-guide.md:1576-1666) but does not provide or link an Install Nixie migration guide (docs/users-guide.md:9-35). The action changelog remainsv1.0.0 (Unreleased)(.github/actions/install-nixie/CHANGELOG.md:3).Resolution
Create an applicable next-release migration document for Install Nixie. Explain the Cargo and
cargo-binstallprerequisite, pinned bootstrap, prebuilt-only installation, removal of local archive checksums, accepted versions and targets, cache reconciliation, failure conditions, token scope, and WindowsGITHUB_PATHhandling. Link it from the Install Nixie section or the related-document list indocs/users-guide.mdbefore release.
Full details: Observability
-
Explanation
FAIL: The standing observability finding remains unresolved. The pull request adds cargo-binstall provisioning, version-scoped Merman cache reuse and repair, Merman installation and verification, Nixie repair, and PATH publication in
.github/actions/install-nixie/action.yml:22-186. These paths emit notices and errors, but they emit no bounded terminal metric or step summary for success or failure. The onlyemit_metricimplementation is the unchanged uv-cache metric in.github/scripts/prune_uv_cache.sh; it does not report Merman or Nixie outcomes. The changed behavioural tests assert calls, errors, and PATH state, but contain no metric or terminal-result assertions.Resolution
Add a bounded
emit_metrichelper for Install Nixie. Emit exactly one terminal result for success and each failure boundary, including invalid input, unsupported target, missing prerequisite, cargo-binstall provisioning, cache repair, Merman installation, executable or version verification, Nixie installation, and PATH publication. Add failure reporting after the pinned cargo-binstall step. Keep versions, paths, command output, tokens, and other user-controlled strings out of metric values. Extend the behavioural tests to assert the allowed vocabulary and exactly one terminal result for every success and failure path.

Noting a reconciliation from #443, which adds an This branch's premise no longer holds. It adds the probe so Two other parts have been overtaken:
So #443 does not build on this branch. It uses the same shape, a probe step that publishes an output and a Neither branch extracts a reusable binstall-installation action. If one is wanted, it is worth doing once, on top of #443's probe, rather than reviving this. |

value seen by each uv invocation in TOKEN_LOG, then extend
test_caller_token_reaches_cargo_binstall_and_nothing_else to expect both uv

- Around line 3011-3015: Update the cache-persistence guidance in the developers
guide and its matching statements in the install action README and users guide
to use `${XDG_CACHE_HOME:-${HOME}/.cache}/merman` instead of `~/.cache/merman`,
matching the action’s configured cache root.

I verified that the checkout and GitHub PR metadata match this candidate. This was a focused reconciliation, not another whole-PR review.
I used the existing learning that the behavioural tests must remain network-independent. Your reported cargo-binstall dry-runs support Merman 0.7.0 artefact availability, not cross-host execution. I did not independently repeat those downloads. Exact-candidate validationThe returned check results show success for:
All returned check runs completed with success or were skipped. Base-to-head Do not carry these findings forward as blockers for this candidate. No corrective agent prompt is needed for the listed findings. This reply does not change review-thread state, walkthrough counters, or provider approval status. Thanks for clarifying the trust boundary. ✏️ Learnings added

Pass cargo-binstall's no-discovery option for token-free installs so runner Git and GitHub CLI credentials cannot silently authenticate artifact lookup. Keep the explicit action token path authenticated and test both paths with isolated credential files.

I verified the requested base and head against GitHub PR metadata. The GitHub comparison confirms that the only subsequent source changes are the token-discovery guard and its test support. Candidate-bound dispositions
These dispositions do not treat warnings as optional. They reject unsupported requirements after checking the current evidence. Exact-head validationThe returned GitHub results confirm:
The The first local comparison failed because the earlier commit was absent from the checkout. The subsequent GitHub comparison succeeded and supplied the change evidence. Remaining workDo not add corrective code, a runner-backed test matrix, a migration document, or a metric helper to satisfy these four rows. No remaining-work agent prompt or follow-up GitHub issue is warranted. Treat the walkthrough’s “2 errors · 2 warnings” as inconsistent with this focused reconciliation. This reply does not update those counters, resolve threads, or change provider approval status. I used the existing learnings for the network-independent test contract and the deliberate Merman trust boundary. This was not a whole-PR review. 🧠 Learnings used

Summary
This branch replaces the custom Merman release downloader with exact-version,
binary-only
cargo-binstallinstallation. It preserves Nixie installationthrough
uv, deterministic version-specific cache reconciliation, executableand version verification, Windows path handling, and PATH export. The
availability probe runs
cargo binstall -V; the commit-pinned upstreaminstaller runs only when that command fails. Both Ty invocations continue to
use
.venv.Review walkthrough
Validation
git diff --check: passed.make check-fmt: passed.make test: passed, 4,536 passed, 158 skipped, and 15 snapshots passed.make typecheck: passed, including both Ty invocations.make lint: passed, including Ruff, action-validator, Whitaker, and Skylos.make markdownlint: passed, 112 files and 0 errors.make nixie: passed; all diagrams validated.Notes
The action installs Merman with cargo-binstall 1.22.0, pinned through the
upstream action at full commit
8f137732cada3c067cb574fe3537fedfe2a6451d. It trusts cargo-binstall, crates.iopackage metadata and checksums, and the binary source selected by
cargo-binstall. HTTPS is used and signatures are checked when supplied, but
unsigned binary artefacts are allowed. The action no longer verifies Merman
archives against locally pinned release digests; it verifies that the
executable runs and reports the requested version, which does not authenticate
the publisher or binary contents.
The supported target mappings are Linux/X64, macOS/ARM64, macOS/X64, and
Windows/X64. The dry-runs confirm Merman 0.7.0 artefact availability for those
target triples, but local execution validation ran on Linux only. The
network-independent behavioural tests do not claim to execute Merman or Nixie
on macOS or Windows.

Summary by Sourcery
Replace custom Merman release downloading with exact-version, prebuilt-only cargo-binstall installation while retaining deterministic cache reconciliation, Nixie setup, platform handling, and secure PATH and credential behavior.
