New DIS scanner detects tools that appear in BOTH permissions.deny
and permissions.allow within the same settings.json file. The deny
list wins, so allow entries are dead config but still load on every
turn and confuse intent.
Tool identity = bare name (everything before "("). `Bash(npm:*)` and
`Bash` are treated as the same tool, so a deny on `Bash` flags any
`Bash(...)` allow entry.
Severity: low. Wired into scan-orchestrator + scoring (area: Settings).
Fixture denied-tools-in-schema has Bash in both arrays; healthy-project
serves as the negative case.
[skip-docs] reason: v5 plan fences off README/CLAUDE.md badge updates
to Session 5; Forgejo pre-commit-docs-gate hook requires this tag.
Tests: 611 → 617 (+6).

New CPS scanner walks CLAUDE.md cascade and flags volatile content
between lines 31 and 150 — the cache-prefix window beyond TOK Pattern
A's top-30 territory. Volatile content anywhere in the cached prefix
forces a fresh cache write from that line down on every turn.
Volatile-pattern set extends TOK Pattern A with:
- shell-exec lines (! prefix) — common in CLAUDE.md to inject git/date
- ${VAR} substitutions — vary per-shell, defeat cache reuse
Severity: medium per finding. Skips lines 1-30 to avoid duplicating
Pattern A's range; CPS' value is in the 31-150 zone.
Wired into scan-orchestrator + scoring SCANNER_AREA_MAP. CPS shares
the "Token Efficiency" area with TOK; scoreByArea now deduplicates by
area name and combines counts across scanners contributing to the
same area, so the 9-area scorecard contract holds.
Fixtures volatile-mid-section/{volatile-line-60, volatile-line-200}
verify both positive (line 60) and out-of-window (line 200) cases.
