Closes #96.

What was wrong

main had no security workflow and no link checker, three of six pipelines could report success while a job had actually failed, two workflows fought over the same GitHub Pages site, and the whole js/ test suite was never executed by CI. Every finding below is backed by a log or a command in dev/log/issues/96/pulls/97/.

False negatives — CI reported success on a broken tree

# Defect Evidence Fix
1 continue-on-error: true masked the Windows C# test failures; the pipeline stayed green while dotnet test failed run 25760911270 removed; the underlying leak fixed (below)
2 TransactionsDecorator / VersionControlDecorator never released their memory-mapped databases, so Windows could not delete the test files reproduced locally both implement IDisposable; CA1001/CA1063/CA1816/CA2000 enabled, TreatWarningsAsErrors on
3 csharp.yml advertised a changeset-pr release mode that no job implemented — selecting it produced a green run that did nothing workflow_dispatch inputs vs. job list job implemented; rust.yml gained the matching changelog-pr mode
4 A dependency bump in Cargo.toml without the matching Cargo.lock update passed CI while every job silently re-resolved the graph cargo metadata --locked exits 101 on drift (verified by temporarily bumping thiserror) lockfile drift check in the Rust lint job
5 js/test/*.test.mjs was never run by any workflow no npm run test:js step existed wired into wasm.yml; it immediately caught defect 8
6 cargo clippy ran without -- -D warnings, so it printed findings and exited 0; rust/wasm was never formatted or linted at all .github/workflows/rust.yml both workspaces gated
7 Every job tested the pull-request head only. A clean textual merge is not necessarily a compiling one experiments/semantic-merge-conflict.sh reproduces it: head green, merged tree red .github/scripts/simulate-fresh-merge.sh + a pull-request-only job in rust.yml and csharp.yml
8 check-web-archive.mjs dropped every lychee error that is not an http URL (missing file, unresolvable root-relative link) and then set all_archived=true, skipping the failure gate run 32145481148 non-http errors are reported and fail the job; covered by check-web-archive.test.mjs
9 No security workflow existed on main, which is why 4 Dependabot alerts sat unnoticed npm audit --audit-level=high on main's lockfile exits 1 with 3 high findings (dev/log/.../local/npm-audit-main.log); this branch's lockfile audits clean security.yml (CodeQL, dependency review, cargo audit, npm audit, secretlint)
10 Nothing scanned the tree for committed secrets, although CI logs are committed under dev/log secretlint job + .secretlintrc.json; the tree scans clean

False positives — CI failed on a healthy tree

# Defect Evidence Fix
11 check-web-archive.mjs scanned the whole lychee report, so bullets under ## Redirects per input were escalated as broken links: lychee reported 4 errors, the script failed the job over 9 links run 32145481148 parses only the ## Errors per input section; regression test over the captured report
12 js/index.html's root-relative links (/favicon.svg, /src/main.jsx) were unresolvable to lychee same run --root-dir passed to lychee
13 DocFX generates csharp/docs/api/*.yml into the build output and the files are deliberately not committed, so the link could never resolve from a source checkout same run .lycheeignore
14 wasm.yml triggered on both pull_request and push to pull-request branches, running every pull request twice .github/workflows/wasm.yml push trigger narrowed to main

Errors

# Defect Evidence Fix
15 https://link-foundation.github.io/link-cli/csharp/ and /rust/link_cli/ returned 404 — both docs.yml and wasm.yml uploaded a Pages artifact, and GitHub Pages serves one site per repository, so the last deployer replaced the other's files curl against the live site: root 200, both sub-paths 404 docs.yml is the only publisher and assembles the workbench (root) plus both API references (/csharp/, /rust/) and a landing page (/docs/) into one artifact
16 Outstanding RUSTSEC advisories in both Cargo.lock files cargo audit anyhow and memmap2 refreshed
17 .gitkeep at the repository root violated js/test/repositoryLayout.test.mjs test failure removed

Warnings

# Warning Fix
18 Node.js 20 is deprecated ... actions/github-script@60a0d83 ... forced to run on Node.js 24codecov/codecov-action@v5 pins github-script v7.0.1 (node20); v6/v7 pin v8.0.0 (node24) bumped to codecov/codecov-action@v7
19 Cannot build an overlay database because build-mode is set to "undefined" and the DEPRECATED autobuild inputs, on all four CodeQL languages build-mode declared per language (autobuild for C#, none elsewhere); deprecated standalone autobuild step removed
20 rust/src/query_processor.rs has 994 lines (approaching limit of 1000) pattern-matching helpers extracted to rust/src/query_processor/matching.rs (794 lines now; no tracked .rs file exceeds the 900-line threshold)
21 C# doc-comment CS1570 warnings fixed

Hardening applied across every workflow

Every job now declares timeout-minutes; every workflow declares a top-level least-privilege permissions:; every job is covered by a concurrency group, with release/Pages jobs in non-cancellable writer groups so a deployment is never killed mid-flight.

How this is prevented from regressing

.github/scripts/workflow-policy.test.mjs — 49 assertions run by rust.yml, csharp.yml, wasm.yml and npm test:

  • every job declares a timeout and is covered by a concurrency group;
  • every workflow declares top-level permissions:;
  • no continue-on-error, no unwrapped if: !... (a YAML tag, not a negation);
  • every advertised release_mode option is handled by a job;
  • no workflow reacts to both pull_request and a non-main push branch;
  • exactly one workflow deploys Pages and exactly one uploads a Pages artifact;
  • every cargo clippy invocation denies warnings;
  • rust.yml and csharp.yml simulate the fresh merge;
  • the JavaScript tests are executed by a workflow.

Run against the pre-fix tree (e4a5085) the suite fails 8 assertions, so it is a genuine regression test rather than a description of the current state.

.github/scripts/check-web-archive.test.mjs covers the lychee parser against a report captured from the failing run, asserting that redirects are not reported as broken and that the parsed error count matches the count lychee itself reports.

.pre-commit-config.yaml mirrors the cheap gates locally.

Reproducing

node --test .github/scripts/*.test.mjs        # 49 workflow policy + parser tests
cd js && npm test                             # 82 tests (layout, link graph, policy, parser)
cargo fmt --manifest-path rust/Cargo.toml --all -- --check
cargo clippy --manifest-path rust/Cargo.toml --all-targets --all-features -- -D warnings
cargo test --manifest-path rust/Cargo.toml --all-features
dotnet test csharp -c Release                 # 222 tests
bash experiments/semantic-merge-conflict.sh   # demonstrates the merge false negative

Reported upstream (issue requirement: "if the same issue is found in template report issue also in templates")

The check-web-archive.mjs defects were inherited from the pipeline templates, so both were reported there with reproducible examples, workarounds and suggested code fixes:

… warnings

NamedLinksDecorator and SimpleLinksDecorator opened memory-mapped file
handles for both the data and the names database but were not disposable,
so callers had no way to release them. On POSIX an unlink of a still-mapped
file succeeds, which hid the leak; on Windows the same delete fails with
IOException. Both decorators now implement IDisposable.

The reflection-based facade-chain disposal previously living inside
NamedTypesDecorator is extracted into the shared LinksFacadeDisposer so all
three decorators release handles identically.

Also escapes Link<uint> as Link{uint} in the ChangesSimplifier doc comment,
which removes the only two CS1570 warnings in the build.
Reproduces and fixes the 114 Windows test failures (226 IOExceptions at
System.IO.FileSystem.DeleteFile) that csharp.yml was hiding behind
continue-on-error.

Every affected helper now scopes its decorator with `using` so the
memory-mapped handles are released before the finally block deletes the
backing files: AdvancedMixedQueryProcessor, NamedTypesDecoratorTests,
NamedLinksDecoratorTests, LinoDatabaseOutputTests, SimpleLinksDecoratorTests,
LinoDatabaseInputTests, PersistentTransformationDecoratorTests and
Issue62ReviewCoverageTests -- the exact eight classes in the failure list.

DecoratorDisposalTests pins the contract: each decorator is IDisposable, its
databases can be deleted after Dispose, and Dispose is idempotent.

Two further fixes in the same area:

- MakeNamesDatabaseFilename_CorrectlyGeneratesFilename hard-coded '/' in its
  expectations while the implementation builds paths with Path.Combine, so it
  failed on Windows only. It now compares the file name and the directory
  separately, and a new theory asserts all three decorators agree.

- RunTestWithLinks capped every test body at one second of wall-clock time,
  which made a loaded macOS runner fail SwapSourceAndTargetForAllLinksUsing-
  VariablesTest with TimeoutException. The guard is now 60 seconds and
  overridable via LINK_CLI_TEST_TIMEOUT_SECONDS.

Measurable on Linux too: a full run used to leave 104 orphaned
*.names.links files in /tmp, now it leaves none.
Adds csharp/Directory.Build.props with TreatWarningsAsErrors and .NET
analyzers enabled, plus csharp/.editorconfig promoting the four
disposal-safety rules (CA1001, CA1063, CA1816, CA2000) to errors.

Fixes everything they surfaced:
- seals the three link decorators (CA1063/CA1816),
- documents the deliberate ownership transfers in MakeLinks and in the
  constructors with justified CA2000 suppressions,
- makes TransactionsDecorator and VersionControlDecorator disposable
  (CA1001); Dispose delegates to the existing Shutdown and rolls back a
  still-open transaction respectively,
- disposes the decorators created in the transactions/version-control
  tests instead of leaking their background workers.

Without this, warnings accumulated silently and CI still reported
success - the false-negative class of issue #96.
Mechanical, whitespace-only pass (verified with 'git diff -w', which
shows nothing but brace placement) so that
'dotnet format --verify-no-changes' can be enforced in CI as the
csharp template does. Build and all 222 tests are unchanged.
- removes 'continue-on-error: windows-latest' from the test matrix: the
  file-locking failures it hid are fixed, so a Windows regression is now
  a red build instead of a green one (the false negative of issue #96),
- adds 'dotnet format --verify-no-changes' and the file-size check to
  the lint job, matching csharp-ai-driven-development-pipeline-template,
- adds per-job timeout-minutes so a hung job fails instead of burning
  the 6h default,
- adds workflow-level least-privilege 'permissions: contents: read',
- replaces the redundant 'always() && !cancelled()' with '!cancelled()',
- keeps cancel-in-progress for PR runs but disables it on main and gives
  the publishing jobs a non-cancellable writer concurrency group.
…or files

Both were over the 1000-line limit enforced by
csharp/scripts/check-file-size.mjs, which is why the check had never
been wired into CI. Splitting them into partial classes is a pure move
of existing code - no member was added, removed or edited:

- Library: matching, mutations and reference validation each move into
  their own partial file (1678 -> 484/425/483/330 lines),
- Tests: the suite splits into two test partials plus a helpers partial
  (1848 -> 704/897/277 lines).

All 222 tests still pass and check-file-size.mjs now exits 0.
…loys

Applies the same hardening as the C# workflow to rust.yml: per-job
timeout-minutes, workflow-level 'permissions: contents: read', a
non-cancellable writer concurrency group for the publishing jobs,
cancel-in-progress disabled on main, and '!cancelled()' in place of the
redundant 'always() && !cancelled()'.

docs.yml and wasm.yml both deploy to GitHub Pages, which accepts only one
deployment per repository at a time, so a push touching both would make
the second deploy fail. They now share a non-cancellable writer group.
…plates

All three ai-driven-development-pipeline templates ship security.yml and
links.yml; link-cli had neither, so dependency vulnerabilities and dead
documentation links went unnoticed - the false-negative class of #96.

- security.yml merges the C#, Rust and JS template jobs: CodeQL over
  csharp/rust/javascript-typescript/actions, dependency-review on PRs,
  cargo audit over both Cargo.lock files and npm audit over js/,
- links.yml is the C# template's lychee checker with the Wayback Machine
  fallback (scripts/check-web-archive.mjs reused verbatim), extended to
  exclude dev/log alongside docs/case-studies,
- 'npm audit fix' in js/ clears the three pre-existing high-severity
  advisories (nanoid, postcss, vite) that the new job would have failed on.
dev/log was swallowed by the '[Ll]og/' rule inherited from the standard
.NET .gitignore, so the collected CI logs, the downloaded template
workflows and the root-cause analysis were never part of the PR. The
rule is now negated for dev/log specifically.
'cargo audit' reported RUSTSEC-2026-0190 (anyhow) and RUSTSEC-2026-0186
(memmap2) as unsoundness warnings for rust/ and rust/wasm/. Both are
fixed in semver-compatible releases, so a plain 'cargo update -p' clears
them: anyhow 1.0.102 -> 1.0.104, memmap2 0.9.10 -> 0.9.11.

cargo fmt, clippy with -Dwarnings and the full test suite stay green.
…olicy tests

The C# pipeline offered a 'changeset-pr' release mode in its
workflow_dispatch input that no job implemented: selecting it produced a
green run that did nothing. Port the changeset-pr job from the C#
pipeline template, and mirror it in the Rust pipeline as changelog-pr
(with the matching release_mode input the Rust template ships).

Add scripts/workflow-policy.test.mjs, which fails on the pre-fix
workflows for every defect fixed in this pull request: missing
timeout-minutes, missing top-level permissions, continue-on-error
masking failures, unwrapped 'if: !cancelled()' and dead release modes.
It runs from both the C# and the Rust lint jobs.
…runs

js/test/*.test.mjs was never invoked by any workflow, so its repository
layout test had been failing unnoticed on a tracked root .gitkeep. Run
'npm run test:js' from the WebAssembly workflow, delete the stray
.gitkeep, and move the repository-wide CI helpers under .github/scripts
so they respect the same layout rule (a root scripts/ directory is
forbidden by that test).

Also drop 'issue-*' from the wasm push trigger: combined with the
pull_request trigger it ran the whole workflow twice for every push to
an issue branch.

Both invariants are now asserted by .github/scripts/workflow-policy.test.mjs.
A Cargo.toml dependency bump without a matching Cargo.lock update used to
pass CI while every job re-resolved the dependency graph on the fly.
'cargo metadata --locked' turns that drift into an explicit failure for
both the CLI crate and the WebAssembly crate.

You are seeing this message because GitHub Code Scanning has recently been set up for this repository, or this pull request contains the workflow file for the Code Scanning tool.

What Enabling Code Scanning Means:

  • The 'Security' tab will display more code scanning analysis results (e.g., for the default branch).
  • Depending on your configuration and choice of analysis tool, future pull requests will be annotated with code scanning analysis results.
  • You will be able to see the analysis results for the pull request's branch on this overview once the scans have completed and the checks have passed.

For more information about GitHub Code Scanning, check out the documentation.

GitHub Pages serves a single site per repository. docs.yml and wasm.yml both
uploaded a Pages artifact, so whichever finished last replaced the other one's
files; the API reference URLs advertised in README.md answered 404:

  https://link-foundation.github.io/link-cli/            -> 200
  https://link-foundation.github.io/link-cli/csharp/     -> 404
  https://link-foundation.github.io/link-cli/rust/link_cli/ -> 404

docs.yml is now the only publisher: it builds the WebAssembly workbench (site
root) together with the DocFX and rustdoc output (/csharp/, /rust/) and an API
landing page (/docs/). wasm.yml keeps only its test job. Two policy tests pin
the single-publisher invariant.

check-web-archive.mjs scanned the whole lychee report, so bullets under
"## Redirects per input" were escalated as broken links: run 32145481148
reported 9 unrecoverable links while lychee itself reported 4 errors. It now
parses only the "Errors per input" section. Conversely, lychee errors that are
not http URLs (a missing DocFX file, an unresolvable root-relative link) were
dropped and the step reported all_archived=true, turning a real failure green;
those are now reported and fail the job. Both defects are covered by
check-web-archive.test.mjs against a report captured from that run.

Three false negatives, all of which let a broken tree report success:

* `cargo clippy` was invoked without `-- -D warnings`, so it printed its
  findings and exited 0. Both Rust workspaces are now gated; both are clean
  today, so the gate is added at zero cost.
* `rust/wasm` was never formatted or linted - the lint job only pointed at
  `rust/Cargo.toml`.
* Every job tested the pull request head. A pull request can be green on its
  own head and still break `main`, because a clean textual merge is not
  necessarily a compiling one. `.github/scripts/simulate-fresh-merge.sh`
  (ported from the Rust pipeline template) merges the head into the current
  tip of the base branch and re-runs the fast checks there; rust.yml and
  csharp.yml each gained a pull-request-only job that uses it, parameterised
  through FRESH_MERGE_CHECKS because this repository builds three stacks from
  one tree.

Policy tests pin all three invariants.

Refs #96
repositoryLayout.test.mjs asserted that wasm.yml deploys GitHub Pages, which
is exactly the duplicate-publisher arrangement that made the API reference
URLs answer 404. Run 32146391570 caught it, which is the point of running
these tests in CI. The guard now asserts that docs.yml publishes the site
(including the workbench it serves at the root) and that wasm.yml uploads no
Pages artifact of its own.

test:js also runs .github/scripts/*.test.mjs now, so `npm test` covers the
workflow policy and lychee report parsers locally, not only in CI.

Refs #96
security.yml checked code (CodeQL) and dependencies (cargo audit, npm audit)
but never the literal contents of the tree. This repository commits CI evidence
under dev/log, which is exactly where a token copied out of a workflow log
would land unnoticed. Adds the templates' secretlint job and .secretlintrc.json;
the current tree scans clean.

.pre-commit-config.yaml mirrors the cheap gates locally (formatting, clippy with
-D warnings, the workflow policy and layout tests), adapted to this monorepo's
per-stack manifests.

Evidence for the audit jobs, collected under dev/log/issues/96/pulls/97/local:
main's js/package-lock.json fails `npm audit --audit-level=high` with 3 high
findings (vite GHSA-fx2h-pf6j-xcff, postcss GHSA-r28c-9q8g-f849) - the four
open Dependabot alerts on the default branch. There was no Security workflow at
all before this branch, which is why they went unnoticed; this branch's
lockfile is already on vite 8.2.1 / postcss 8.5.26 and audits clean.

Refs #96
Three warnings were present in every run and none of them failed anything, so
they had been accumulating (issue #96, requirement "fix all warnings"):

* "Node.js 20 is deprecated ... actions/github-script@60a0d83 ... forced to run
  on Node.js 24" in the C# test job. codecov/codecov-action@v5 pins
  github-script v7.0.1 (node20); v6 and v7 pin v8.0.0 (node24). Bumped to v7;
  the action's inputs we use are unchanged.
* "Cannot build an overlay database because build-mode is set to 'undefined'"
  plus the DEPRECATED autobuild inputs, on all four CodeQL languages.
  build-mode is now declared per language (autobuild for C#, none for Rust,
  JavaScript/TypeScript and Actions) and the deprecated standalone autobuild
  step is gone.
* "rust/src/query_processor.rs has 994 lines (approaching limit of 1000)".
  The pattern-matching helpers moved to rust/src/query_processor/matching.rs,
  following the split already applied to transactions and version_control;
  query_processor.rs is now 794 lines and no tracked .rs file exceeds the
  900-line warning threshold.

cargo fmt, cargo clippy -D warnings and cargo test --all-features are clean
after the extraction.

Working session summary

All six checks are green on de0d1e9 and PR #97 is out of draft: #97

Check Result
Rust CI/CD Pipeline success
C# CI/CD Pipeline success
WebAssembly CI success
Docs success
Security success
Broken Link Checker success

Working tree is clean and origin/main is an ancestor of the branch head.

The PR title dropped [WIP] and the description now documents all 21 findings with per-item evidence: the lychee redirect false positive (4 reported errors escalated to 9), the non-http false negative that set all_archived=true, continue-on-error masking the Windows C# failures, unlinted rust/wasm and clippy without -D warnings, js/ tests never run in CI, the unimplemented changeset-pr/changelog-pr release modes, Cargo.lock drift, the missing fresh-merge simulation, the absent security workflow behind the 4 unnoticed Dependabot alerts, the Pages 404 root cause (two workflows publishing to one site), the codecov node20 and CodeQL build-mode warnings, and the 994-line query_processor.rs. It also links the three upstream reports (csharp #47, rust #136, js #138) and points at dev/log/issues/96/pulls/97/ for the raw logs.

One thing to flag explicitly, since it's the user's call rather than mine: a few template features are still not ported and I listed them nowhere in the PR body — the JS lint stack (eslint.config.js, .prettierrc, .jscpd.json, eslint-rules/no-changelog-comments.js), scripts/check-pipeline-status.sh, the smoke-test scripts, check-file-line-limits.sh / check-mjs-syntax.sh, and the templates' per-workflow policy tests. Requirement R5 asks to compare all files against the templates, so these are arguably in scope; I left them out because each adds a new gate rather than fixing an existing defect. Say the word and I'll add them in this PR.
