- BUG_REVIEW.md was a transient artifact from the post-merge bug-hunt review; the actual fixes shipped in PR #32 and are documented in the PR description / commit history. - CLI_MIGRATION.md is an audience-specific guide (Java MS-GF+ users porting CLI invocations) — belongs under docs/, not at root. - DOCS.md stays at root as the primary single-file reference (per the iter39 docs-rewrite design). - Updated inbound references in README.md and DOCS.md.
Adds the design spec for PR-Q1 (post-cutover code quality sweep) and finalizes the inbound-reference updates from the prior commit (docs/CLI_MIGRATION.md links) that weren't staged at that point. PR-Q1 is the first of three sequential sub-projects (quality -> speed -> ID-rate +5% per dataset). Decomposed during the 2026-05-26 brainstorm because the three concerns differ in risk, scope, and time profile; the ID-rate target is a multi-PR research project, not a single ship gate. Scope: 7 groups (6 in-PR + 1 out-of-repo memory update). Dangling .java:LINE refs (42), stale "port of MS-GF+" framing, identifier renames (MSGFRUST_RSS_PROBE etc.), 26 clippy warnings, lift CI lint to required, remove shipped design specs.
The Java source tree was removed in commit b4565b8 during the Rust-cutover; the inline citations to specific Java line numbers now point at code that does not exist in this repo. Replace each citation with intent-only "Java parity" comments. Preserves semantic meaning; removes the broken hyperlinks. Parity-test files (tests/*_java_parity.rs, tests/gf_bsa_parity.rs, tests/*_match_java.rs) untouched — their identity is Java parity and the citations are load-bearing documentation. 8 non-test files touched, 33 refs replaced, 0 functional changes.
The codebase is post-cutover; new contributors should read crate-lib top-of-file doc comments as descriptions of what each crate does, not as port-bookkeeping. CLI --help and enum doc comments that compared behavior to Java's command-line options now describe behavior directly. KEEPS user-facing provenance: - README.md and DOCS.md project-lineage sections - Legacy numeric flag values (Java MS-GF+ -X) in --help (user migration) - (Java -precursorCal) in precursor_cal doc (exact flag name we mirror) - docs/parity-analysis/** content - Parity test files Touched: 5 crate-lib headers + msgf-rust CLI framing.
The "MSGFRUST_" prefix dates from an early iter-era naming and does not match the binary's identity (msgf-rust). Switch the primary name to MSGF_RSS_PROBE and accept the legacy name for this release with a one-line deprecation warning on stderr. The legacy name will be removed in the next quality cleanup. Side-effect-only env var; no functional change to search/scoring.
Brings the workspace to clippy-clean on stable 1.87.0 so the CI lint job can be lifted from advisory to required in the next commit. Changes by class: - map_or simplifications: mechanical rewrite via clippy --fix - complex-type aliases: SegmentPartitionCache, SegmentPartitionSlice, DeconvResult, and RankKeptCtx struct in crates/scoring/src/scoring/scored_spectrum.rs - too_many_arguments: RankKeptCtx context struct in scored_spectrum.rs; #[allow] with reason for directional_node_score_inner, write_tsv, write_tsv_to, write_spectrum_rows, and compute_cleavage_credit - doc-list indentation: add blank line after list / fix continuation indent at 15 sites in msgf-rust.rs and scored_spectrum.rs - unused_mut, ? rewrite, manual split_once, loop-counter: via clippy --fix - needless_range_loop: suppressed with reason (seg indexes cache AND serves as fallback partition_for arg) No functional behavior change; PIN/TSV bit-identical regression gate in tree (precursor_cal_bit_identical) is the verification.
After PR-Q1 Task 4 left the workspace clippy-clean on --lib targets, remove continue-on-error from the lint job's clippy step and extend the lint command to --all-targets (covers tests + examples + bin in addition to lib). Also addresses 5 residual warnings in test/example targets that the --lib-only fix in Task 4 didn't reach: - crates/scoring/examples/dump_main_ion.rs: struct field shorthand - crates/scoring/examples/dump_prefix_cache.rs: needless_range_loop - crates/scoring/tests/add_prob_dist_chunked_parity.rs: unnecessary parens Rustfmt remains advisory (~11k lines of fmt churn pending; separate cleanup). Lint job now blocks PRs on clippy regressions.
Deletes the iter39 docs-rewrite spec and plan (shipped 2026-05-23 via PR #30; the rewrite is in dev and being relied on, so the design docs no longer need to be discoverable in the repo). Their lineage is in git history. Tracks the in-flight PR-Q1 implementation plan alongside its design spec (committed in 55cff3f). Future protocol: when a docs/specs design file references a feature that has fully shipped and closed any deferred gate, remove it in the next quality cleanup.

Three non-blocking observations from the final code review: 1. DOCS.md §97 documented only the legacy MSGFRUST_RSS_PROBE name. Now mentions MSGF_RSS_PROBE as the canonical with the legacy noted. 2. crates/model/src/amino_acid.rs:13 inline comment referenced the legacy name; updated to MSGF_RSS_PROBE. 3. log_rss deprecation warning fired on every call when only the legacy env var was set. Guard with std::sync::Once so it prints exactly once per process invocation. All non-functional; verification: deprecation warning count is now 1 under MSGFRUST_RSS_PROBE=1 + multiple log_rss checkpoints.

Closing without merging. After running the 3-dataset bench on the branch (LFQ/Astral/TMT, off + auto), all 6 PSM cells came in within rayon noise floor vs the pre-cleanup baseline (max delta ±56 PSMs) and wall-time deltas were entangled with VM load contention during the bench window (load average 1.19 -> 9.43 between back-to-back PR-A and PR-Q1 runs). The cleanup commits are real (clippy clean, lint gate, dangling Java refs scrubbed, MSGFRUST_RSS_PROBE rename with legacy compat), but they don't deliver measurable PSM or speed wins on their own. Branch |
After PR #35 (PR-Q1) closed unmerged for not delivering measurable wins, pivot strategy: stack 3 loosely-coupled sub-features on top of the cleanup commits and ship ONE PR with bench-gated value. Sub-features: - S1: profile-guided Astral wall reduction (gate: -5% wall) - S2: LFQ calibrator threshold fallback 1e-6 -> 1e-5 (gate: +50 PSMs) - S3: additive PrecursorErrorPpmSquared PIN column (gate: +50 PSMs on any one dataset) Each sub-feature ships only if its bench gate passes; failures get dropped before merge.
Summary
