Introduces structured test category rules (GTCS-001/002/003) so agents classify each test case before writing it, making INV and DIR coverage gaps explicit rather than silently absent. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Fixes structural issue where original Added items were orphaned under Changed, merges duplicate Changed sections, and adds version link. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…opters Template development decisions belong in DECISIONS_ARCHIVE.md, not in DECISIONS.md which adopters inherit as a clean starter log. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…RCHIVE.md DECISIONS.md now contains only the header and a commented entry template. Template-internal decisions moved to DECISIONS_ARCHIVE.md which was missing. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Summary
rules/global/test-coverage-spec.md— three global rules (GTCS-001/002/003) introducing the MFT/INV/DIR taxonomy: classify each test case into exactly one category before writing it; scale-based coverage floors (Small ≥1, Medium ≥2, Large ≥3); absent categories must be stated with a specific reason in the structured preamble or test-file header.skills/test-and-fix-loop/SKILL.md— added "Test category classification" section (table, workflow, INV-vs-DIR heuristic, scenario examples); four new conformance self-check items;rulesfield in YAML front matter referencingtest-coverage-spec.md.rules/global/code-quality-baseline.md— peer-rule cross-reference totest-coverage-spec.mdfor agent discoverability.DECISIONS.md— decision entry with context, alternatives considered, and constraints introduced.CHANGELOG.md— Added and Changed entries.No CI files changed. All changes are adapter-neutral markdown.
