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.
[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: 604 → 611 (+7).

Adds detectMcpToolBudget detection block in TOK scanner. Tiered severity
per project-local .mcp.json server based on toolCount:
- < 20: no finding
- 20-49: low
- 50-99: medium
- 100+: high
- null (manifest unparseable): low + "tool count unknown" message
Scoped to source==='.mcp.json' to keep findings actionable for the
audited path; plugin/user-level MCP servers are surfaced by the
manifest scanner (Step 19 / N2).
5 fixtures (mcp-budget/{14,25,60,120,unknown}-tools) use inline `tools`
arrays in .mcp.json — no node_modules needed for these tests.
Tests assert title+severity (not exact ID) since TOK IDs are sequential
per scan, not semantic per pattern.
[skip-docs] reason: v5 plan fences off README/CLAUDE.md badge updates
to Session 5; Forgejo pre-commit-docs-gate hook requires this tag on
feat commits without doc changes.

Filesystem counts are the source of truth; README badges parsed via
line-anchored substring (badge/<kind>-<N>-...). Emits readmeCheck object
with counts/badges/mismatches.
CLI: node scanners/self-audit.mjs --check-readme [--json]
API: runSelfAudit({ checkReadme: true }) → result.readmeCheck
Helper: checkReadmeBadges(pluginDir) for per-fixture testing
New fixture: readme-desynced/ (commands/foo + bar, README claims 1).
Note: alpha phase does NOT require result.readmeCheck.passed === true.
Self-test of real plugin currently fails (scanners 10 vs 9, tests 31 vs 543);
will be reconciled in Session 5 Step 28 (README sync).
582 → 586 tests, all green.
The mcp-tool-heavy fixture relies on node_modules/mcp-heavy/package.json
being committed so the v5 M1 tool-count detection test runs deterministically.
Add an unignore rule for tests/fixtures/**/node_modules/.
- New Pattern F in TOK: low-severity finding when SKILL.md description > 500 chars
- Scoped to discovery.files (project-local) — activeConfig.skills walk would
pull in user/plugin skills out of project scope
- New fixtures: skill-bloated (594-char desc) + skill-tight (46-char baseline)
574 → 576 tests, all green.
- New Pattern E in TOK: emits medium finding when activeConfig.claudeMd.estimatedTokens > 10_000
- Uses cascade tokens, file count, and calibration note as evidence
- New fixtures: large-cascade (37k bytes / 14475 cascade tokens) + small-cascade (5k baseline)
572 → 574 tests, all green.
Removes the v4 'void readActiveConfig' placeholder and wires the
active-config snapshot into the TOK scanner.
Per-turn behavior changes:
- Each enabled MCP server becomes its own hotspot entry (richer than
the parent .mcp.json file alone)
- total_estimated_tokens now includes MCP server cost
- result.activeConfig exposes a small summary
(claudeMdEstimatedTokens, mcpServerCount, pluginCount, skillCount)
Failures of readActiveConfig are non-fatal — the scanner falls back
to the discovery-only path used in v4.
Tests: +3 cases on the new tok-active-config fixture
(.mcp.json with 2 servers, CLAUDE.md, plugin skeleton).
