Closes A3 of v7.1.0 critical-review patch. Each rewrite preserves the underlying
claim where it is accurate but removes hype/overreach language. Historical
CHANGELOG/README version-table rows are intentionally left as-is (they document
what was claimed at the time of release, not what is true today).
Changes (CLAUDE.md, commands/ide-scan.md, knowledge/mitigation-matrix.md,
docs/security-hardening-guide.md):
- "Trustworthy scoring (BREAKING)" → "Severity-dominated risk scoring
(v2 model, BREAKING)". Removes hype framing; describes the actual mechanism.
- "Context-aware entropy scanner" → "Rule-based entropy scanner with
file-extension skip, 8 line-level suppression rules, and configurable policy".
No ML/context inference; just rules.
- "1487 tests" → "1511 unit and integration tests; mutation-testing coverage
not published". Updated count after A1+A2 (+24) and added qualifier.
- "Fully Schrems II compatible" → "Schrems II compatible in default offline
mode. Optional OSV.dev enrichment (`supply-chain-recheck --online`)
transmits package identifiers to a Google-operated API and is a separate
compliance consideration." Acknowledges the OSV.dev opt-in caveat.
- "Rule of Two enforcement" → "Rule of Two detection (configurable; default
warn; blocks on high-confidence trifectas in opt-in `block` mode; distributed
trifectas detected but not blocked by default)". "Enforcement" implied
block; default is warn.
- "Hardened ZIP extractor" → suffix " — no fuzz-testing results published
to date". Caps and class-of-attacks rejected are accurate; absence of
formal fuzz coverage now stated.
- "defense-in-depth" — preserved as framing, but quantified in
security-hardening-guide §4: "three independent detection layers with
documented bypass classes". Each layer named, each layer's known bypasses
pointed to (critical-review §4 evasion arsenal).
Tests: 1511/1511 green (no behavioural change).
E2E verification against content-heavy repo (`content-claude-code`) revealed
413 entropy findings (8 HIGH / 405 MEDIUM) from markdown image CDN URLs in
JSON content indexes — e.g., ``.
These are legitimate content-repo artifacts, not credentials. The 40-char
hash segment in the CDN URL trips Shannon entropy (H=5.29 over 300 chars),
and rule 13 (inline <svg>) doesn't match since there's no literal `<svg>`
tag — the `.svg` is just a URL path suffix.
Added rule 18 `MARKDOWN_IMAGE = /!\[[^\]]*\]\(\s*https?:\/\//` — matches
`` / ``. Line-level (not string-level) so URL
is not over-specific.
E2E impact on `content-claude-code`:
- Before: BLOCK / 65 / 8H 437M 0L
- After: WARNING / 56 / 3H 427M 0L
Hyperframes unchanged: BLOCK / 80 / 1C 4H 92M — real CRITICAL SQL-injection
and HIGH findings still detected.
Tests: 2 new (positive + negative fixture) bringing entropy-context to 26,
total suite 1485 → 1487.
Docs updated to "rules 11-18" and "8 new line-suppression rules".

Final commit in the trustworthy-scoring series. Bundles verdict cutoff
alignment, the last suite of tests, and all documentation touch-points
that quote version numbers or describe v7.0.0 behaviour.
Verdict/band co-monotonicity
- `scanners/lib/severity.mjs` — verdict cutoffs moved from 61/21 to 65/15
so `BLOCK >= 65`, `WARNING >= 15` locks onto the v2 riskBand() boundaries.
Prevents "BLOCK / Medium band" contradictions under the v2 formula.
Scanner hardening (bug fixes from v7.0.0 testing)
- `scanners/entropy-scanner.mjs` — `policy_source` now uses
`existsSync('.llm-security/policy.json')` instead of value-based check.
Old heuristic always reported 'policy.json' because DEFAULT_POLICY now
carries an `entropy.thresholds` section.
- `scanners/lib/file-discovery.mjs` — `.sass` and GPU shader extensions
(`.glsl, .frag, .vert, .shader, .wgsl`) added to TEXT_EXTENSIONS. Without
this, shader files were invisible to file-discovery, so they were never
counted as skipped by the entropy-scanner extension filter.
Tests
- `tests/scanners/entropy-context.test.mjs` (new, 24 tests) — A. File-ext
skip (4), B. Line-level rules 11-17 (8), C. Policy overrides (3).
Fixtures generate 80-char base64 payloads at runtime via
`crypto.randomBytes` to dodge the plugin's own pre-edit credential hook
on the test source.
- `tests/lib/severity.test.mjs` — rewritten with v2 scoring table (70
tests total, was 52).
- `tests/lib/output.test.mjs:243` — "1 critical = score 80" under v2
(was 25 under v1).
- Full suite: 1485/1485 green (was 1461).
Docs
- `CHANGELOG.md` — v7.0.0 entry with BREAKING CHANGES section.
- `README.md` (plugin + marketplace root) — version badge, history table,
plugin-card version string, test count.
- `CLAUDE.md` — header version, "v7.0.0 — Trustworthy scoring" summary
paragraph at the top.
- `docs/security-hardening-guide.md` — new section 6 "Calibration & false
positives" documenting v2 formula, context-aware entropy scanner,
typosquat allowlist, and §6.4 tuning workflow. Existing "Recommended
baseline" section renumbered to §7.
Version bump
- `6.6.0 -> 7.0.0` across package.json, .claude-plugin/plugin.json,
scanners/ide-extension-scanner.mjs VERSION const, README badge,
CLAUDE.md header, marketplace root README card.
