Walkthrough

Changes

Specification tooling and development workflow

Layer / File(s) Summary
Duvet and development tool packaging
npins/sources.json, scripts/gen-pins.sh, nix/pkgs/duvet/..., nix/overlays/..., default.nix
Duvet is pinned and packaged with a viewer stub. The development shell adds Duvet, Deno, and Cargo tooling.
Coverage and workflow commands
justfile
Coverage accepts a configurable Bolero duration and emits LCOV output. New recipes run Duvet, mutation tests, citation interlock checks, and summary generation.
Citation interlock execution
scripts/spec-interlock.ts
The new CLI resolves citations, checks implementation and test mappings, runs targeted mutation checks, evaluates coverage and baselines, and writes requirement results.
Compliance report rendering and workflow integration
scripts/duvet-summary.ts, .github/workflows/dev.yml, net/src/packet/utils.rs
The summary CLI renders compliance and interlock results. The pinact step receives GITHUB_TOKEN, and Packet::ip_proto suppresses missing-documentation warnings.

Suggested reviewers: fredi-raspall

Merge Risk: 🔴 Critical · up to 32306

The new compliance-summary command cannot run because its TypeScript source is syntactically invalid, and the snapshot validation can pass without checking a committed snapshot. These issues can disable required checks or produce misleading results, so the PR is not merge-ready until they are fixed.

An untracked .duvet/snapshot.txt makes this gate pass without comparing anything.

The file test at Line 785 only proves the path exists. git diff reports changes for tracked paths. If .duvet/snapshot.txt exists in the worktree but is not tracked by git, git diff --quiet succeeds for any content, so duvet report can rewrite the snapshot and the gate still passes. That is the same "cannot tell drift from nothing" failure the comment above describes.

Add a tracked-path test next to the existing existence test.

Stale accepts corrupt the requirement tally.

Line 1027 adds stale.length to failures, and Line 1046 computes the holding-requirement count as triples.length - failures. A stale accept is not a requirement, so the printed count understates the requirements that hold, and it becomes negative when stale accepts outnumber the checked requirements. The exit code already reports the failure, so the count does not need to carry it.

Count stale accepts separately from requirement verdicts.

🛡️ Proposed fix
   const stale = ACCEPTED.filter((entry) => !used.has(entry));
   const checkedAll = !args.only.length;
+  let staleAccepts = 0;
   if (stale.length && checkedAll) {
-    failures += stale.length;
+    staleAccepts = stale.length;

A surviving mutant has two possible causes needing opposite fixes.

814-839: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Stale accepts still corrupt the requirement tally.

Line 817 adds stale.length to failures, and Line 836 computes the holding count as triples.length - failures. A stale accept is not a requirement verdict, so the printed count understates the requirements that hold. The count becomes negative when stale accepts outnumber the checked requirements. The exit code can report the stale accepts on its own.

Count stale accepts separately from requirement verdicts.

🛡️ Proposed fix
   const stale = ACCEPTED.filter((entry) => !used.has(entry));
   const checkedAll = !args.only.length;
+  let staleAccepts = 0;
   if (stale.length && checkedAll) {
-    failures += stale.length;
+    staleAccepts = stale.length;
     console.log();
   console.log(
     `${
       triples.length - failures
     }/${triples.length} requirements hold their citations`,
   );
-  return failures ? 1 : 0;
+  if (staleAccepts) {
+    console.log(`${staleAccepts} accepts match no surviving mutant`);
+  }
+  return failures || staleAccepts ? 1 : 0;

- Around line 814-839: Update the stale-accept handling around stale and
failures so stale.length is tracked separately from requirement verdict failures
rather than added to failures. Compute the displayed holding count from
requirement verdict failures only, while preserving stale-accept reporting and
ensuring the exit code still fails when stale accepts exist.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

An empty coverage map for the cited region still labels every survivor "unreached".

lineCounts returns null only when a cargo step fails or the report is unreadable. If the report is readable but holds no segment for the cited files, counts is non-null and executable.length is 0. reached() then returns false for every mutant, so all survivors land in unreached. Line 758 then prints "the test never runs these lines" without evidence for that claim.

Split the survivors only when the coverage map covers the cited region.

🛡️ Proposed fix
+  // No intersection with the cited region is not evidence about any line in it.
+  const classify = Boolean(counts) && executable.length > 0;
   const reached = (mutant: string) => {
     const match = MUTANT_LINE.exec(mutant);
     return match ? (counts!.get(`${match[1]}:${match[2]}`) ?? 0) > 0 : false;
   };
   return {
     outcome: missed.length ? "decorative" : "held",
     caught,
     missed,
     accepted,
-    unreached: counts ? missed.filter((m) => !reached(m)) : [],

A few minor changes and a question. Please at least read the commit messages and comments and see if they make sense. Some of them sound like gibberish.

Otherwise, good to go.

I am just no longer going to add in comments. Nobody else does and they are just distracting anyway

Terminate the regular-expression literal.

At scripts/duvet-summary.ts:84, id.replace contains an unterminated regular-expression literal. The TypeScript module is syntactically invalid, so the compliance-summary command cannot run. Use id.replace(/^https?:\/\//, "").
