Summary

• load non-hidden .mise/conf.d/*.toml files as project configuration fragments
• preserve alphabetical fragment precedence while keeping .mise/config.toml authoritative
• reuse the existing project trust root, tracking, write-target exclusion, and .mise/mise.lock routing
• make deprecated automatic monorepo discovery glob-aware so fragment-only roots are detected consistently with explicit roots

Details

The project config discovery list already supported .config/mise/conf.d/*.toml, while the config-root and lockfile helpers already understood .mise/conf.d. The missing piece was the discovery pattern itself. This adds that pattern immediately below .mise/config.toml in precedence, filters hidden files consistently with global/system conf.d, and routes every downstream feature through the existing config pipeline.

📝 Walkthrough

Walkthrough

The configuration loader now discovers non-hidden TOML fragments in .mise/conf.d and .config/mise/conf.d, loads them alphabetically, and includes them in project detection. Tests and documentation cover precedence, lockfiles, write targets, and monorepo discovery.

Changes

Configuration discovery and validation

Layer / File(s)	Summary
Filtered conf.d loading src/config/mod.rs	Configuration globbing excludes hidden files and includes .mise/conf.d/*.toml in local configuration discovery.
Project configuration detection src/config/mod.rs	Configuration presence checks and monorepo discovery use filtered wildcard matching.
Fragment behavior and documentation e2e/config/test_project_config_confd_slow, src/config/mod.rs, docs/configuration.md	Tests verify precedence, hidden-file exclusion, lockfile handling, write targets, and monorepo discovery. Documentation describes fragment loading and project configuration paths.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 422bc

This change adds support for project configuration fragments with documentation and an end-to-end test; no actionable merge-blocking risk remains beyond normal checks and review.

Poem

I’m a rabbit who sorts TOML with care,
Hidden fragments stay out of the lair.
Alphabetical leaves fall into place,
Tasks and locks keep a tidy pace.
Config paths now clearly show,
Hop, hop—watch the projects grow!

Greptile Summary

This PR adds project-local .mise/conf.d/*.toml fragment support and aligns project discovery with existing conf.d behavior.

• Loads non-hidden project fragments in deterministic precedence order.
• Recognizes fragment-only projects during explicit and automatic monorepo discovery.
• Keeps fragments from becoming implicit write targets and routes their lockfiles to .mise/mise.lock.
• Adds unit, end-to-end, and documentation coverage for discovery, precedence, tasks, tools, environment values, and lockfiles.

Confidence Score: 5/5

The PR appears safe to merge, with no actionable correctness or security defects identified.

The new project fragment path is applied consistently across loading and monorepo discovery, while precedence, hidden-file exclusion, lockfile placement, and write-target behavior are explicitly covered.

Important Files Changed

Filename	Overview
src/config/mod.rs	Adds filtered project conf.d discovery consistently across configuration loading and monorepo root detection, with explicit precedence tests.
e2e/config/test_project_config_confd_slow	Exercises fragment merging, hidden-file exclusion, lockfile placement, write-target behavior, and monorepo discovery.
docs/configuration.md	Documents project-local conf.d fragments and clarifies that only non-hidden TOML files are loaded.
