Greptile SummaryThis PR adds opt-in complete lockfile generation while retaining incremental merge behavior as the default.
Confidence Score: 5/5The PR appears safe to merge, with no outstanding actionable findings. No new correctness, security, or repository-rule violations remain. The previous provenance finding was resolved after jdx documented the intentional trust-model change and Greptile withdrew the concern. Important Files Changed

Source fallback blocked by provenance check
Medium Severity
Installed source-fallback metadata is selected, then ensure_no_downgrade still compares it to the previous binary entry. Missing provenance on the source install is treated as a downgrade, so generation fails and the lockfile is not published after a successful source install.

The rejection is intentional when fallback would remove recorded provenance: the approved plan requires both reconciling actual source fallback and preserving downgrade protection. Source fallback without a prior provenance commitment is reconciled and covered by actual_source_fallback_wins_over_reusable_binary_metadata. A fallback that loses a previous provenance/signing commitment must preserve the old lockfile and return an error; the completed installation remains on disk. Automatically exempting source fallback here would silently weaken the required policy.

In `@e2e/lockfile/test_lockfile_generate`:
- Line 40: Update the lockfile test around the merge-mode mise install and the
subsequent generate-mode mise lock so the expected-file comparison occurs
immediately after `mise install`, before regeneration can modify `mise.lock`;
retain the existing comparison after generation if needed to validate both
modes.
In `@src/backend/aqua.rs`:
- Around line 1435-1445: Update verify_provenance_at_lock_time in
src/backend/aqua.rs so the computed SHA-256 checksum is assigned only when
checksum is None; preserve any validated incoming checksum and its algorithm
otherwise. This ensures same_checksum_algorithm compares the original algorithm
correctly. The cited src/backend/github.rs lines 1350-1360 require no change.
In `@src/backend/github.rs`:
- Around line 1082-1089: Update resolve_github_asset_url_for_target and the
corresponding GitLab and Forgejo asset-resolution functions so an explicit
asset_pattern with no matching asset returns
crate::errors::Error::UnsupportedTarget instead of a plain eyre error. Preserve
existing behavior for successful matches and other asset-resolution failures,
allowing generate mode to skip unsupported targets consistently.
In `@src/http.rs`:
- Around line 900-904: Update the generate-mode branch in generate_lockfiles()
to acquire the destination-derived lock before writing, rather than relying only
on INVOCATION_DOWNLOADS, and replace the direct file::copy to path with
PartialDownload::persist so the destination is committed atomically. Preserve
the existing parent-directory creation and metadata return behavior.
- Around line 885-899: Bound the generate-mode artifact cache managed by
InvocationDownloads with concurrency-safe eviction of idle entries, tracking
active users so an entry is never removed while another caller may still use its
shared download. Evict least-recently-used inactive TempDir entries when the
configured capacity is exceeded, while preserving shared reuse and cleanup of
evicted temporary directories.
In `@src/lockfile/generate.rs`:
- Around line 203-210: Update the RESOLUTIONS key construction in generate to
canonicalize both ToolOptions maps before formatting: sort the entries of
tv.request.options() and tv.install_env() by key, then format those ordered
representations. Preserve the existing key components and ensure equivalent
ToolVersion values produce the same key regardless of insertion order.
In `@src/plugins/core/python.rs`:
- Around line 1229-1242: Update the verify_github_artifact_attestations handling
in src/plugins/core/python.rs at lines 1229-1242 and src/plugins/core/ruby.rs at
lines 1219-1233 so AttestationError::NoAttestations clears provenance and
continues lockfile generation instead of propagating the error; preserve
propagation for other errors and the existing invalid-attestation behavior.
In `@src/plugins/core/ruby.rs`:
- Around line 843-852: Update the reuse_provenance branch before assigning
verified to call detect_precompiled_provenance(), and only allow reuse when it
confirms a GitHub repository source; preserve the existing GitHub attestations
setting validation and ensure unsupported sources are not recorded as
GithubAttestations.

Addressed the valid review findings in 3d32a6e:
The legacy provenance flag remains inert as explicitly requested (Greptile has acknowledged and withdrawn that concern). Source fallback remains subject to existing provenance/signer downgrade protection: successful installs stay on disk, but a policy downgrade does not publish a new lockfile. Validation: focused lockfile tests, isolated generator tests, snapshot recheck regression, and scoped formatting/checks passed. Continuing to follow CI and reviews on the new head.

Addressed the additional-artifact ordering note from review 5159198075 in e5fecff. Unchanged artifact URLs now retain their own provenance baseline regardless of list order. Unmatched replacement URLs are paired in configured order, preserving the existing upgrade policy rather than rejecting every versioned URL change. Regression coverage exercises reordering, a valid replacement URL, provenance loss, and removal of a verified artifact. Both focused tests, formatting, and workspace/all-features/all-targets Clippy pass. The explicit-pattern and missing-attestation failures noted in the summary remain intentional policy decisions, as explained in the corresponding resolved threads.

Instruction countsNothing was compared, and so nothing was gated. No series appears on both sides: either the base has no measurements recorded, or the two were measured on different runner classes, which are deliberately not comparable — counts shift between machine types by more than a real regression does. New, nothing to compare against: Only instruction counts gate. Wall clock is shown for context — on identical hardware it moves 4-20% run to run. Measured by tak — instruction-counted CLI benchmarks, stored in this repository's git notes.

The performance gate did not measure this revision: its build failed downloading futures-executor because the runner could not resolve static.crates.io. This is a dependency-download/DNS failure, not an observed instruction-count regression. I reran the failed jobs in https://github.com/jdx/mise/actions/runs/34403082694. All build, unit, e2e, lint, and documentation checks on e5fecff are green; the performance measurement remains pending. AI-assisted — Tool: Codex; model: OpenAI/unavailable; version: unavailable. |
Summary
Trial complete lockfile generation behind
lockfile_mode = "generate"/MISE_LOCKFILE_MODE=generate. The unset default remainsmerge; selecting an engine does not enable automatic lockfile creation or change formats.This addresses the broader cause of cross-platform churn in Discussion #13018: host-scoped incremental updates can discard another platform's option variant before auto-locking recreates it. The generator starts from current requests and uses previous files as immutable inputs for pinned versions, target platforms, reusable artifact metadata, and provenance baselines.
Implementation
lock.provenance_verifiedas a trust signal in both modes. Preserve existing values as inert metadata for unchanged artifacts; new provenance is cryptographically verified for each target, including additional artifacts. Keep checksum checks and provenance policy enforcement.Validation

Note
High Risk
Changes lockfile trust semantics, install/lock orchestration, and atomic publication paths across backends—security-sensitive provenance handling with broad behavioral impact when
generateis enabled.Overview
Adds
lockfile_mode = "generate"(via settings orMISE_LOCKFILE_MODE) as a trial alternative to incrementalmerge. In generate mode,mise lockand eligiblemise installruns rebuild lockfiles from current config/task requests while treating the previous file as an immutable baseline—reusing unchanged artifacts, carrying forward filtered scope, and publishing through staged atomic writes with snapshot rechecks so failures or concurrent edits do not overwrite good lockfiles.Provenance and backends now record only cryptographically verified provenance per target platform (including cross-platform lock resolution); failed lock-time verification fails the command instead of deferring.
provenance_verifiedis no longer a trust signal (preserved only as legacy metadata on unchanged entries). Aqua/GitHub/Python lock paths gain per-target verification, stricter checksum handling, andUnsupportedTargetsemantics that generate mode treats differently from hard failures. HTTP deduplicates downloads and attestation checks within a command when generating.Install/upgrade can trigger background lock preparation during install, skip legacy monorepo migration in generate mode, and run
Lock::generate_after_installwhen lockfiles are enabled. A build-time release gate (build/lockfile_rollout.rs) forces an explicit maintainer decision before shipping 2026.12.0. Docs, schema, and e2e tests cover mode switching, overlap, monorepos, and concurrent edits.Reviewed by Cursor Bugbot for commit e5fecff. Bugbot is set up for automated code reviews on this repo.
