Every command so far asked an addition question — what to add, what to move, what it costs. Nothing asked what is no longer earning its always-loaded rent. This adds that axis as a fourth lensCheck on the existing hybrid motor rather than a new scanner or a 22nd command: the measured payoff (~18% of one file) justifies a mode, not machinery. It is the only lens that proposes REMOVING config, so it carries a guarantee the others don't need: a load-bearing block is never a candidate. Precision is asymmetric — a missed dead line costs a few tokens per turn, a deleted one costs a wrong remote or a broken script — so the floor is decided in code (lib/floor-exclusion.mjs) before the opus judge sees anything, never in prose. Granularity is the leaf block, with two structural exceptions: a paragraph ending in ':' merges with the list it introduces, and an ordered list is a contract whose steps inherit floor from any sibling. Unordered lists deliberately do not inherit — a load-bearing bullet and a disposable one routinely share a list, and container-reasoning is the error the hand-built ground truth exists to catch. Verified against that ground truth (built before any classifier existed), with the comparison machine-checked rather than read by eye: zero load-bearing blocks proposed, 11/18 deletable groups surfaced, ~756 tok ~ 18% of a ~4300 token file — inside the pre-registered band. The first run found five floor violations the synthesized fixture missed; each got a structural rule and a fixture shape so it cannot regress. Three real bugs the dogfood run exposed, all now covered: - JS \b is ASCII-only, so /\bunngå\b/ never matches — every Norwegian keyword ending in æ/ø/å was silently dead. - A bare word/word is not a path; "pros/cons" vetoed the largest deletable block until PATH_RE was tightened to rooted paths and globs. - "Mid-sentence" must key on a preceding lowercase letter; the loose version read **bold labels:** and quoted openers as entities, costing 4 of 11 groups. BP-SUB-001 is grounded entirely in the Anthropic steering blog already cited by BP-MECH-001..004 and asserts nothing from the talk that motivated the feature — no "80%", no ablation figure. Suite 1365 -> 1382/0. Frozen v5.0.0 snapshots untouched; plain optimize output byte-identical on identical input (--subtract adds keys only when passed). knowledge-refresh-cli's reference date moved to 2026-08-01: its premise that every seed entry was verified 2026-06-20 expired when BP-SUB-001 got a genuine verification date, and backdating the entry to fit the test would have been a lie about when its source was checked.

Config-Audit Plugin
Claude Code Configuration Intelligence — know if your config is correct, find what could improve it, fix it automatically. Three pillars: Health (deterministic scanners), Opportunities (context-aware recommendations), Action (auto-fix with backup/rollback).
Per-command flags, patterns, and feature lists live in README.md and /config-audit help. This file carries what's invariant for working on the plugin.

Reference docs (read on demand)
docs/scanner-internals.md— scanner inventory, lib modules, action engines, knowledge base, per-scanner/per-block implementation notes (design rationale, primary-source verification, byte-stability lessons)docs/humanizer.md— plain-language output (v5.1.0), humanizer vocabularies, output modes
Plain-Language Output (v5.1.0)
Default output of all commands routes through humanizeEnvelope (lib/humanizer.mjs), decorating each finding with userImpactCategory, userActionLanguage, and relevanceContext. --raw and --json bypass the humanizer for byte-stable v5.0.0 output. Full detail: docs/humanizer.md.
Suppressions
Create .config-audit-ignore at project root — one exact ID or glob per line (CA-SET-003, CA-GAP-*). Suppressed findings are tracked in the envelope's suppressed_findings for audit trail. Disable with --no-suppress.
Architecture
Workflow: /config-audit → discover + analyze (auto) → plan → implement → verify. Auto-detects scope from git context; override with full|repo|home|current; --delta for incremental. Session state lives under ~/.claude/config-audit/sessions/{id}/ (scope.yaml, discovery.json, state.yaml, findings/, analysis-report.md, action-plan.md, backups/, implementation-log.md).
Finding ID format: CA-{SCANNER}-{NNN} — e.g. CA-CML-001, CA-SET-003, CA-HKV-002, CA-RUL-005, CA-TOK-005, CA-CPS-001, CA-SKL-001, CA-OST-001, CA-OPT-001, CA-AGT-001.
Conventions
Enforced conventions live in .claude/rules/ (auto-loaded as project instructions):
ux-rules.md— output/narration/formatting for all commands (never dump raw JSON, narrate before each step, space-separated command suggestions)command-development.md— required command frontmatter +plugin:actionnamingagent-development.md— agent frontmatter + "when to use" conventionsstate-management.md— updatestate.yamlafter every workflow phase
Coding style: scanners are zero-dependency Node ESM; new findings use the CA-{SCANNER}-{NNN} ID format; byte-stable CLIs are verified against frozen tests/snapshots/v5.0.0/ baselines.
Subtraction floor (invariant). optimize --subtract is the only lens that proposes removing config, so scanners/lib/floor-exclusion.mjs runs as a deterministic pre-step before the judge — a load-bearing block is never a candidate, and that guarantee must not be moved into the agent prompt. Two rules follow from it: (1) staleness is not a deletion signal — an outdated version pin inside a floor block is a drift/CA-CML dead-reference concern; (2) tier 2 ≠ tier 3 — a compensatory block that keeps earning its place returns, and reporting it as dead weight is wrong even when the label matches. Norwegian keywords need the Unicode boundaries in subtraction-prefilter.mjs; JS \b is ASCII-only, so /\bunngå\b/ silently never matches.
Testing
node --test 'tests/**/*.test.mjs'
Test fixtures in tests/fixtures/. Per-scanner and per-build-block implementation notes (design rationale, primary-source verification, byte-stability lessons) live in docs/scanner-internals.md → Implementation notes.
Gotchas
- Session directories accumulate — use
/config-audit cleanupto manage - Scanners run on Node.js ≥ 18 (uses node:test, node:fs/promises)
- Plugin CLAUDE.md files in node_modules should be excluded via scope
