ADR-v2-109 — Local Style-Consistency Enforcer (Vale-lite)

Status: Accepted (2026-07-02) · Wave M Context links: gec (grammar), corrdict (misrecognitions), [[adr-v2-114-acronym-glossary-manager]], [[adr-011]]

Context

Wave M research (#5) — a user/house style sheet ("e-mail not email", US spelling, "cannot" not "can not", expand vs contract) applied to each dictation so terminology stays consistent across a document — a proselint/Vale pass, fully offline. Grammar Repair fixes grammar and the Self-Learning Correction Dictionary fixes misrecognitions; neither enforces stylistic/terminological consistency against a user rulebook. Distinct linter class. Anchor: Vale (errata-ai) and proselint — established rule-based prose linters; editorial "standardize on first use" conventions — all rule-table driven, no ML.

Decision

Add an opt-in Style-Consistency Enforcer: [styleguard] enabled=false. Pure cores in styleguard/rules.py: load_stylerules(items) → a list of Rule(pattern, replacement, ignore_case, regex), and apply_style(text, rules) → (rewritten, [Change(before, after)]) (word rules match on \b boundaries; regex rules apply verbatim). Pure regex; no dependency. OFF by default.

Consequences

  • Consistent terminology/style without a manual editing pass; user-supplied rulebook.
  • Pure regex engine → fully testable.
  • Distinct from GEC (style vs grammar) and Correction Dictionary (style vs misrecognition).
  • Privacy (ADR-011): local text only.
  • Caveat: literal/regex rules only (no NLP-aware rules); off by default.
