Block tracker references and volatile history in source

[HackingGate]

The tracker-reference rule only scanned Markdown, RST, and text files, allowing a systemd Documentation= field to point to a volatile issue. Extend it to source and configuration, including repository issue shorthand, while preserving standards citations and the existing test-directory exclusions.

Also reject authoring-date headers across source files, conventional changelog files, and committed log files. Document that durable explanations belong in the repository, reports and benchmark results belong in issues, and edit chronology belongs in Git history. Arbitrary pasted reports and narrative history still require review.

Update the bundled-set lock, add regression coverage for the systemd field and legitimate content, and remove issue-history comments found in uphold's own source.

Validation: full Rust test suite passed; the final rule revisions passed the corpus and bundled-set lock tests. Clippy, formatting, generated-reference checks, and the repository policy scan passed.

📝 Walkthrough

Walkthrough

The process-residue policy now detects more date and tracker-reference forms, changelog filenames, and committed logs. The lockfile, corpus tests, integration tests, reference documentation, and related comments were updated.

Changes

Process-residue policy

Layer / File(s)	Summary
Update process-residue rules policy/base/process-residue.toml, policy/base/sets.lock.json	The policy broadens date and tracker matching, adds changelog and log filename rules, and updates exclusions.
Validate rule behavior tests/base_set_corpus.rs	Corpus and integration tests cover the new matches, exclusions, and allowed literals.
Document and remove process references docs/REFERENCE.md, src/guard/names.rs, src/shim.rs	The reference documentation describes the rule scope. Historical issue and behavior references are removed from comments.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Feature

Merge Risk: 🟡 Moderate · up to d5379

Markdown files can retain authoring-date headers in HTML comments despite the expanded policy. Fix the matcher and regenerate the lock before merge; the documentation wording should also identify GitHub as the supported URL host.

tracker references and the covered source, configuration, and documentation
locations.
