It evaluates arbitrary target+-- repositories through four progressive compliance levels (L0–L3) and generates+-- incremental remediation plans to bring builds under strict compiler discipline.+--+-- = Architectural Context & Invariants+--+-- Note [Progressive Quality Gate Realization and Incremental Compliance Levels]+-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~+-- [tag:note-progressive-quality-gates]+-- The Progressive Quality Gate Realization engine ("Milestone 4.3") bridges the gap+-- between overlay installation ("Milestone 4.2") and empirical validation ("Milestone 4.4")+-- by evaluating a target codebase against four strictly ordered compliance levels:+--+-- 1. __Level 0 (Foundation):__+-- Scaffolding, documentation skeletons, and turnkey verification harnesses are physically+-- present and configured. This is the baseline established by Milestones 4.1 and 4.2.+-- Gates: @.git@ initialized, @.githooks/@ present, @bin/<project>-verify@ present (+x),+-- @tagref.yml@ present, @.hlint.yaml@ present, @README.md@ present, @PLAN.md@ present.+--+-- 2. __Level 1 (Structural Integrity):__+-- Tagref cross-references certify zero dangling pointers across code, comments, and+-- documentation. Markdown link & anchor integrity holds with zero broken links. The+-- verification harness scripts execute successfully.+-- Gates: @tagref@ exits 0, @linkcheck@ exits 0.+--+-- 3. __Level 2 (Compiler Discipline):__+-- The Haskell build compiles cleanly under @-Wall -Wcompat -Wredundant-constraints@+-- with @cabal build all@ reporting zero warnings. Build artifacts can be produced+-- without any source modifications to domain logic.+-- Gates: @cabal build all 2>&1 | grep -c warning@ == 0.+--+-- 4. __Level 3 (Static Analysis Purity):__+-- HLint reports zero hints across all production source files under the project's+-- @.hlint.yaml@ configuration. Comment density meets the 25.0% gate threshold with+-- 50.0%+ target on @src/@. The full test suite passes cleanly.+-- Gates: @hlint@ exits 0, CLOC density >= 25.0%, @cabal test all@ passes.+--+-- === Monotonic Progression Invariant+--+-- Quality levels are strictly monotonically ordered: achieving Level N requires that all+-- gates in Levels 0 through N-1 are already satisfied. The evaluator reports the highest+-- achieved level and all failing gates preventing progression:+--+-- @+-- L0 ⊂ L1 ⊂ L2 ⊂ L3+-- @+--+-- This ensures incremental tractability: teams address foundation first, then structural+-- integrity, then compiler discipline, then static analysis purity — never skipping steps.+--+-- Per Note [Non-Destructive Skeleton Overlay] [ref:note-nondestructive-retrofit], all+-- evaluation is strictly observational and non-destructive.
