feat(metrics): quality-metrics harness with its own dispatchable workflow - #2339

…, shear and layer gates The first slice of spec 30. `just metrics` runs the collectors and writes a schema-v1 snapshot: whole-tree counts of every strict lint and the three complexity lints, line coverage through nextest under a coverage profile, tokei size per crate, module cycles and orphans per crate, unused dependencies, the crate-layer check over cargo metadata, and hotspots ranked by churn times findings. Gates come from metrics/thresholds.toml; the verdict is the worst gate. A collector that cannot run is recorded as not measured and the run exits non-zero, never clean. `just metrics-layers` is the no-compile layer check and joins `just ci`. metrics/layers.toml carries the layer table derived from docs/architecture.md and the edges the tree still carries as dated exceptions. architecture.md §3 gains minzoned in the session plane and a pointer to the enforced table. scripts/metrics_test.sh is the fixture harness the spec's verify lines name; crates/common/tests/shell_harnesses.rs picks it up. lint-shell.sh now recurses so scripts/metrics/ is shellchecked. Measured here with the sandbox's rustc 1.98 (the tree pins 1.97): the strict pass completes with exit 0 and five diagnostics outside the strict set, all from lints newer than the pin. CI measures with the pin. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…rofiler check The first full run over the tree showed three collector faults. cargo-modules runs its --acyclic check before its filters, so every type owning a method that uses the type read as a cycle; the module graph is now dumped as DOT per target and the collector finds the strongly connected components itself, leaving out edges through the crate root and test modules, which are structure. Orphans were the union over a crate's targets, so every binary-only module read as an orphan of the library; they are now the intersection. And a toolchain built without the profiler runtime cannot compile under -C instrument-coverage; the run says so before paying for a cold instrumented build. modules.cycles moves from a zero ceiling to a down ratchet: the tree carries sibling-module cycles today, the largest in sessions and minimald.

Third change of the quality-metrics work (spec 30): the history side of the snapshot pipeline. scripts/metrics/dashboard.py renders a snapshot history into one self-contained index.html (QM-016): inline SVG, a style block, no script, nothing fetched, light and dark via prefers-color-scheme. It charts coverage, strict and complexity lint totals, unused dependencies, code size and layer edges over snapshot date, with a heading and a table of the drawn values under every chart; from the newest snapshot it lists the gates, the top hotspots and the promotable strict lints. A metric a snapshot did not measure is a gap in the line, not a zero. Files that fail schema.py are skipped and named on the page. The page carries no timestamp, so the same history renders the same bytes. scripts/metrics/prune.py keeps every snapshot within ninety days of the newest and the earliest of each month beyond that, decided from the file names alone (QM-015); keep() is a pure function the harness checks the spec's property against. --dry-run lists without deleting. The justfile gains metrics-dashboard and metrics-prune over a .scratch/metrics/history checkout of the metrics-data branch. A synthetic fixture history under scripts/metrics/testdata/history, one snapshot with coverage null, backs the new harness cases prune_keeps_daily_then_monthly and dashboard_renders_offline_with_tables. metrics/README.md documents the dashboard and the retention rule.

Full mode gains an `experimental` step (skipped by `--no-experimental` and
in static mode) that runs rustqual per in-scope crate over its `src/`,
leaving remote-proto out because its code is generated into OUT_DIR, and
cargo-anatomy once over the workspace. collect.py records them under
`crates.<name>.experimental.{rustqual,anatomy}` and
`workspace.experimental`; the whole block is null only when neither tool
ran. Nothing in `metric()` or `evaluate_gates` reads the block, and the
harness asserts that from the source as well as from the verdict (QM-005).
A missing tool is a not_measured entry, a tool failing on one crate is an
`error` in that crate's block, and neither fails the run.
install-tools.sh gets an `experimental_pins` array installed only with
`--experimental`; `--check` lists those pins as optional. The schema
requires the `rustqual` and `anatomy` keys when the block is present.
Both collectors are fixture-verified only: neither rustqual nor
cargo-anatomy installs in this sandbox (crates.io downloads are blocked
and there are no prebuilt binaries), so the fixtures follow the tools'
published docs, every lookup is a `.get`, and testdata/SHAPES.md records
which shapes are unverified against a run. The run.sh branch was
exercised end to end with shims standing in for the two binaries.

Coverage says a line ran, not that a test would notice it being wrong. Two collectors fill the `mutants` and `crap` blocks the snapshot schema already reserved (spec 30, QM-017). `run.sh mutants [BASE]` diffs the working tree against the merge-base with BASE (origin/main by default), the way clippy-strict.sh does, and hands the hunks to `cargo mutants --in-diff` under nextest; the scope is recorded as `in-diff`. An untracked `*.rs` file is not in that diff, so it is listed under `untracked_outside_scope` rather than silently left out. `full` tests one of seven workspace shards chosen by the weekday and records the shard; `--no-mutants` skips it. The baseline suite is green only on Linux, so mutants mode refuses to start on Darwin and the nightly records the collector as not measured there. A diff that reaches no mutant, and a baseline that fails, are told apart by the presence of outcomes.json and the baseline's own outcome in it. collect.py attributes each mutant by its file to a crate and reports tested, caught, missed, timeout and unviable with the score as caught over caught + missed + timeout; an unviable mutant never compiled and says nothing about the tests. A crate the run generated no mutants for stays null, not a perfect score. cargo-crap runs after coverage on the lcov.info it wrote, through one `run_crap <lcov> <out>` hook so the diff mode can reuse it; functions strictly over `[crap] threshold` are counted per crate and in the workspace. Gates: `mutants.score_pct` is an unseeded floor until the shards have gone round the week once; `crap.over_threshold` is a ratchet down, because the tree carries such functions today and a ceiling of zero would be red from the start. The `.minimal` task `mutants` (graph wire.rs only) becomes `metrics-mutants`, pinned to the same cargo-mutants the install script pins. Fixtures outcomes.json and crap.json follow the shapes of cargo-mutants 27.1.0 and cargo-crap 0.7.0 as run on a throwaway workspace; the harness cases named by QM-017 drive run.sh with a fake cargo that logs its argv.

…d-lines helper Grade a change against its base ref (spec 30, QM-009 to QM-013, QM-N01), on top of the snapshot pipeline. scripts/metrics/diff.py reads two things the change cannot write: the thresholds at the merge-base with the base ref and the newest snapshot on the history ref (origin/metrics-data). Each gate is evaluated against the stricter of the base's threshold and the head's (floors take the max, ceilings and ratchet tolerances the min, a gate only one side declares is kept), so a pull request may tighten the bar at once and loosen it only after review has merged the loosening. The gates are re-evaluated with collect.py's own evaluate_gates, never a copy. With no baseline every ratchet is not_evaluated and the report says so. report.md and report.json carry no times (meta.json does), so identical inputs give identical bytes; report.md is appended to GITHUB_STEP_SUMMARY when that names a writable file. When head's compiling collectors covered a subset of the workspace, the baseline's clippy and coverage totals are re-summed over the same crates before the ratchets compare them. run.sh grows two modes. `gate` is the no-compiler grade: the review runtime runs a declared task as a probe with a 300 s budget, no arguments and the sha256 of its output recorded as evidence, so the task takes no parameters, derives its base ref itself, runs nothing that reaches rustc (cargo metadata --no-deps only; cargo-shear is skipped and recorded as not measured because its full cargo metadata probes rustc -vV) and ends stdout with `quality-gate: <verdict> report=<path> sha256=<hex>`. It takes well under a second on this tree. `diff` adds clippy over the crates the change touched, scoped the way clippy-strict.sh scopes itself; --coverage adds llvm-cov. `just metrics-diff [BASE]` drives it. .minimal/minimal.toml declares the quality-gate task and ends agent-verify with the same run. The base-ref resolution and changed-range extraction move out of clippy-strict.sh into scripts/lib/changed-lines.sh, and the range parsing into scripts/metrics/changed_lines.py, so the two gates agree on which lines are the branch's own. clippy-strict.sh keeps its output and exit codes; a harness case drives it against a fixture repo with a canned cargo and checks the seeded hit (2), the clean run (0) and the no-change run. Harness cases: base_thresholds_win_when_stricter (with a randomised property check over stricter()), no_baseline_means_not_evaluated, report_carries_every_section, step_summary_is_appended, gate_runs_without_rustc (fake rustc and cargo-clippy exit 99 and log every call; the log must stay empty), darwin_scope_lists_uncovered_crates_in_report, gate_fits_probe_budget, clippy_strict_unchanged, and report_is_byte_stable now covers the report.

The nightly `metrics` job runs `just metrics`, renders the dashboard from the fetched history plus the new snapshot, uploads both as an artifact, and on main hands the snapshot to scripts/metrics/publish-snapshot.sh. That script keeps the history on the orphan `metrics-data` branch: it fetches or creates the branch in a temporary worktree, adds history/<date>-<sha7>.json, prunes, commits as the Actions bot and pushes with a refspec that names the branch on both sides, so it cannot reach main. It refuses a snapshot whose mode is not full or whose tree was dirty. Non-blocking while it beds in; `notify` is untouched. Verified here: the harness pushes to a bare fixture remote and asserts main is untouched, the branch is an orphan, and refusals exit 2; zizmor 1.30.1 reports no findings on the workflow. actionlint is not packaged for this sandbox and did not run. This touches .github/workflows/, which is CODEOWNER-gated. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…sees exit 3 The case ran green alone and red once inside the full suite while a cargo build held the checkout; the message now carries run.sh's FAILED line so a recurrence says which collector it was. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
1.99.0 is current stable (2026-09-28). The metrics snapshot is measured with the pin, so a pin two releases old would record lint counts that no developer's clippy agrees with. Comments that state the pin follow it. Not built here: the sandbox packages rustc 1.98.1 and nothing newer, so `just clippy -D warnings` under 1.99 is proved by the lanes, not locally. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
`full` and `static` runs now write summary.md beside the snapshot (the verdict, every gate, the workspace totals, module cycles, promotable lints and the top hotspots) and append it to GITHUB_STEP_SUMMARY when set, so the nightly's summary page shows the snapshot without opening the artifact. The grading modes keep appending their report instead. The experimental harness case failed once more with the collector now named: cargo shear could not load a git dependency while another cargo held the same CARGO_HOME. Concurrent use of one cargo home, not the collector; green alone and in a serial suite run. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…he last snapshot Clippy 1.99 under -D warnings found: needless borrows of a Copy closure in args; double_must_use on tonic-generated async_trait code in remote-proto (expected at the include, generated code); the new pedantic assert_is_empty in sessions and paths, allowed in their hand-kept tables since the rewrite says less at the site; must_use on functions returning types already must_use, and three accessors without it, in sessions; a single-element loop in mfile; chunks_exact(2) over a byte slice in minimald-rpc and the switch checksum, now as_chunks; Result<_, ()> on three session-host methods whose only error is a dead host, expected with that reason; and the fetch_update deprecation in a minvmd test helper, expected until the MSRV floor reaches the rename. The nightly's mutation scope changes. A weekday shard of the workspace is about 2,500 mutants (cargo mutants --list), which no 120-minute job can run; run #112 was in that phase when this was written. The nightly now tests the lines changed since the newest snapshot in the history (or the merge-base with origin/main on a branch), under a wall-clock budget (MINIMAL_METRICS_MUTANTS_BUDGET_SECS, 2700 by default); a run that hits the budget reports what it tested with `partial` set, since cargo-mutants rewrites outcomes.json after every mutant. The snapshot records the reference under `mutants.since`. Verified with a standalone 1.99.0 toolchain: workspace clippy clean, fmt clean, clippy-strict clean on the changed lines, the touched crates' tests green except minvmd's port_holder_is_none_when_the_lookup_fails, which reads the host socket table and fails in this sandbox on main as well.

Coverage is a cold instrumented build and the module graphs load every crate; the mutation run takes what is left of the 120-minute job. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
actions/upload-artifact refuses a path with a colon, and the per-target DOT files were named crate.bin:<name>.dot. The target label is now bin-<name>. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
On a fresh runner cargo-shear ran before anything had fetched the git dependencies, so its --offline metadata failed. run.sh now fetches once before it. cargo llvm-cov exited 100 (nextest: tests failed under the instrumented build) and took the whole coverage result with it; it now runs with --ignore-run-fail, and the failing tests are counted from nextest's junit and recorded under workspace.coverage, on the summary page too, so the number is read with its caveat beside it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
rustqual and cargo-anatomy have no prebuilt binaries, so the job compiles them from crates.io and goes on without them when that fails; the snapshot records the two collectors as not measured in that case. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Run inside the nightly's coverage pass, the gate cases inherited GITHUB_STEP_SUMMARY and wrote a grading report of HEAD against itself above the snapshot on the metrics job's summary page. The harness unsets the variable; the cases that check the append set their own file. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…yer table minimal-tui folded into the minimal crate and the sessions crate became boxes on main, so the table named two crates that no longer exist and left boxes unassigned. The metadata fixture is regenerated from the merged tree.
…-tests metrics.yml takes the job unchanged and runs on workflow_dispatch as well as workflow_call, so a snapshot can be taken without the rest of the nightly. continue-on-error moves inside the called job, since a job that calls a reusable workflow cannot set it.

arch-review: PASS · the full ruling
The design of record does not govern this change. It says nothing about the CI workflows, the metrics harness, the lint policy or the toolchain pin of this repository. The crate edits are lint fixes, and they keep behaviour. They do not move a security boundary, a default or a crate owner. This is a PASS by absence, with no conditions. The new workflow under the frozen .github/workflows/ needs CODEOWNER approval. That is a repository rule, not a design line.

Review on Karl's behalf, at 311ce34c1. This is a comment, not an approval. Nothing was built for it: every point comes from reading the code, and each finding says how it was checked.
- CI at head 311ce34: green on every lane aggregator, including KVM and macOS.
minimal-review,coderabbit-reviewandCodeRabbitreported NEUTRAL. - Existing reviews: a long history. minimal-review's last full review was at 13c569a (2 findings, none blocking, and the author replied to both). CodeRabbit last approved at 0a6511a on Oct 25. Both Nov 9 re-triggers were rate limited, so no CodeRabbit review exists for the commits after that. The only commits after 13c569a are two
Merge branch 'main'commits, so the reviewed content is effectively at head. No human approval.
Conflicts with main: none. git merge-tree against current origin/main (21 commits ahead) is clean. Main touched only two of the same files since the merge-base, .minimal/minimal.toml and Cargo.toml, in separate hunks ([defaults.task] and memchr), so nothing is clobbered. I extracted the merged tree and ran layers.py --metadata against its cargo metadata --no-deps: 146 edges, 3 excepted, 0 forbidden, 0 unassigned (exit 0). So the new metrics-layers step in just ci is green on today's crate set.
Workflow triggers and permissions (.github/workflows/metrics.yml, nightly-tests.yml): sound.
- Triggers are only
workflow_dispatchandworkflow_call. There is no PR trigger and nopull_request_target. - The collector job runs at
contents: readwithpersist-credentials: false. It runs crates.iocargo installs and the test suite. publishis the only writer. It is main-only, gated on status 0/2, and checks out main and runs main'spublish-snapshot.shover the artifact, pushing only tometrics-data.- The caller grants
contents: writeto the reusable workflow, and the collector narrows itself back to read. - Both jobs are
continue-on-error, andnotifydoes notneedthem. - No existing job is renamed.
nightly-tests.ymlonly adds ametricsjob and changes a comment. - It is a
.github/workflows/change, so it needs a CODEOWNER approval.
Should-fix
- Dangling spec references:
docs/ci-strategy.md:337andmetrics/README.md:4link todocs/specs/31-spec-quality-metrics/31-spec-quality-metrics.md.metrics.yml,run.sh,layers.py,.minimal/minimal.tomlandthresholds.tomlcite QM-xxx requirement IDs from that spec.- The spec is not in this PR or on main; only
30-spec-pkg-verifyexists. The PR body even says "(not yet in the tree)". - Scenario: a reader follows the link from ci-strategy and gets a 404, and none of the QM IDs can be checked against a requirement. AGENTS.md requires a spec for epic work.
- Land the spec first or in this PR, or drop the links until it lands. Verified with
git ls-tree -r origin/main docs/specsandgit grep 31-spec-quality-metrics refs/review/pr-2339.
Nit
.minimal/minimal.toml[tasks.agent-verify](new last line):scripts/metrics/run.sh gateruns underset -e, so a gate verdict offail(exit 2) now fails the runtime's post-task gate. PR CI never fails on it, because no lane runs the gate. Scenario: an agent task that adds a crate without ametrics/layers.tomlentry getslayers.unassigned> 0 and fails agent-verify, while every CI lane stays green. That may be intended, sincejust cigainsmetrics-layerstoo, but the PR describes metrics as "non-blocking while it beds in". Confirm the intent, or append|| trueuntil the gate has soaked. Verified by readingrun.shexit codes (lines 48-56, 682-686) andthresholds.toml. Not run.Cargo.toml:49now says "The build toolchain pin is 1.99.0", butrust-toolchain.tomlon main is1.99.1. The PR body's "pins Rust 1.99.0" is stale for the same reason.- Operational note: the runtime refused
/reviseon this branch because it modifies.minimal/minimal.toml(comment 2026-10-20). Any further revision has to be done by a person.
Verdict: needs changes. The spec-31 references must resolve. Architecture, triggers and permissions are fine, and the PR merges cleanly. A CODEOWNER sign-off is still needed for the workflow files.
Not done
- I built nothing locally. The #3170 compile evidence comes from the CI job log, and the #3129 regex was run locally in bash.
- I did not fetch review threads for any PR. I used the review and comment bodies from one

Agreed, checking four fields isn't enough. This was the LOW finding at ac6cfc4, and the fix I said would come in the next push still hasn't landed. Before merge, A schema check can't catch a compromised collector that writes plausible in-range numbers. That needs a trusted recompute, which is out of scope for this PR. The remaining risk is bounded: the workflow has no PR trigger, publishes only from main, pins its tools, and its job is non-blocking. I'm leaving this thread open until the push lands. |
rust-toolchain.toml pins 1.99.1, not 1.99.0.
The spec and its QM requirement ids exist on no branch, so the links and ids pointed nowhere. Comments keep what the ids meant; the docs point at metrics/README.md.
The gate still runs and prints its report, but a failed (2) or incomplete (3) verdict is logged instead of failing the task until the gate has soaked.

Review on Karl's behalf, at 0eba25045. This is a comment, not an approval. Nothing was run locally: each point comes from reading the code at head, and each finding says how it was checked.
- CI: green at head (32 passed, 5 skipped), commitlint included. It merges cleanly with current
main. - Since my last full review (
311ce34c): all three earlier points are fixed. The spec 31 links and QM IDs are gone (nothing in the PR mentions spec 31 now). The quality gate inagent-verifyis non-blocking. The toolchain comment says 1.99.1, matchingrust-toolchain.toml.publish-snapshot.shnow refuses a snapshot thatschema.pyrejects, andmetrics_test.shcovers it with a wrongschema_versionand a malformedgates, each refused with exit 2. The rest of the diff since then is comment cleanup. .github/workflows/metrics.ymlchanges, so this still needs a CODEOWNER approval.
Should-fix
docs/fuzzing.md:267still saysminimal run mutants, but this PR renames the task to[tasks.metrics-mutants](.minimal/minimal.toml:56). Scenario: someone copies the command from the fuzzing doc and gets a missing-task error. Checked withgit show 0eba25045:docs/fuzzing.mdagainst the task table. Noted earlier as riding the next push; it is not in yet.
Still open from @norrietaylor's comment (low)
- The comment says
publish-snapshot.shwill, before merge, also cap the snapshot's size and reject unknown fields and out-of-range values. None of that is at head: the script has no size check, andschema.validatechecks that required fields exist with the right types but does not reject extra fields or check ranges (greppedschema.py). The risk is bounded, since publish runs only onmainwithmain's script and the collector holds no write token, but the work was promised for this PR.
Verdict: needs one more push with the docs/fuzzing.md fix and, ideally, the size cap and stricter schema. After that it looks ready to approve, plus the CODEOWNER sign-off for the workflow.
…task publish-snapshot.sh refuses a snapshot over 8 MiB before parsing it, so an artifact cannot bloat the history branch every later run fetches. docs/fuzzing.md names the task this branch renamed, metrics-mutants.

Approving at acf52dff on Karl's behalf. The docs/fuzzing.md should-fix and the snapshot size cap are both in, and the size cap has a test. Rejecting unknown fields and out-of-range values is left to the author, as discussed in the publish-snapshot.sh thread. The metrics.yml change still needs a CODEOWNER approval.
