The CC settings schema is passthrough (verified against the 2.1.193 binary): it
forwards unrecognized keys unchanged rather than rejecting them, so an arbitrary
unknown key is valid/forward-compatible, not an error — the finding's "silently
ignored" claim was factually wrong. The only real risk is a TYPO of a real key
(the intended setting then silently has no effect). Fix: flag an unknown key only
when it closely matches a known key (new levenshtein helper; edit distance <= 2,
both keys >= 4 chars); severity medium -> low; honest passthrough framing in the
scanner + humanizer. Also refreshed KNOWN_KEYS with 6 binary-verified keys
(agentPushNotifEnabled, remoteControlAtStartup, skipAutoPermissionPrompt,
skipDangerousModePermissionPrompt, skipWorkflowUsageWarning, tui). Suite 1341/0
(+12). Frozen v5.0.0 snapshots untouched (0 CA-SET findings there), no re-seed.
Dogfood ~/.claude/settings.json 6->0 (all 6 keys above were false unknown-key
findings; 0 typo flags introduced across 167 walked files).
CLAUDE.md token estimates counted block-level <!-- --> HTML comments toward
always-loaded tokens, but CC strips them before injection (preserved only inside
code fences, per code.claude.com/docs/en/memory). Fix: new stripInjectedHtmlComments
+ effectiveMemoryBytes in active-config-reader; the CML cascade (walkClaudeMdCascade)
and token-hotspots now size CLAUDE.md from effective (stripped) bytes, while raw byte
figures stay honest. Block-level only — inline comments retained (conservative,
verified scope). Suite 1329/0 (+13). Frozen v5.0.0 snapshots untouched (no fixture
has <!--), no re-seed. Dogfood ~/.claude CLAUDE.md ~3386->3301 tok (~85 tok discount,
matches worklist prediction).
A directory named `backups` holds backup COPIES, not live config, so walking
it during a config audit produces stale findings. config-audit's own session
backups (~/.claude/config-audit/backups/<ts>/files/.../CLAUDE.md) were the
canonical case: a ~/.claude-scope audit walked 36 frozen config copies as if
live, polluting CPS (C3) and HKV/RUL (C6) results. Same non-live-noise family
as M-BUG-2.
- Add `backups` to SKIP_DIRS (broad, name-based — consistent with vendor/dist/
.cache): the rule is general, a backups/ dir is never live config.
TDD: 2 failing tests (no config under backups/ discovered + backups/ counted
as skipped) -> green; a third asserts live config beside the backups tree is
still discovered. Full suite 1310/0 (+3). Byte-stable: no fixture is named
`backups` and `backups` appears in zero frozen snapshots, so v5.0.0 + SC-5 +
default-output outputs are unchanged. Dogfooding ~/.claude: files under
/backups/ drop from 36 -> 0; 717 live config files retained.

enumerateAgents previously counted every .md in an agents dir as an
always-loaded agent. Per the official CC subagents docs, CC registers a
subagent only when its frontmatter declares both name and description, scans
agents dirs recursively, and (at a HOME self-scan) must not count
~/.claude/agents twice.
- M-BUG-5: require valid name+description frontmatter; frontmatter-less files
are registration no-ops costing 0 always-loaded tokens. Fixes the user-agent
over-count (this machine: 13 -> 0).
- M-BUG-3: listMarkdownFiles gains opt-in recursion; enumerateAgents recurses
so agents in subfolders (agents/review/x.md) are counted, matching CC.
- M-BUG-4: configDirs dedupes project==user paths, so a `manifest --global`
self-scan (repoPath===$HOME) counts ~/.claude once (user scope), killing the
spurious "project 13" double-count. Benefits rules/agents/output-styles.
TDD: 4 failing tests -> green. Full suite 1305/0; --json/--raw byte-stable,
frozen v5.0.0 + SC-5 + default-output snapshots untouched (no snapshot records
agent enumeration rows).

active-config-reader walked ~/.claude/plugins/marketplaces and ignored both the
enabledPlugins toggle and the polyrepo cache layout. On a polyrepo machine it
counted disabled/uninstalled marketplaces plugins as "active" while MISSING the
actually-enabled plugins installed under plugins/cache. This corrupted the agent
listing and every pluginList consumer (manifest, AGT, whats-active, hooks, rules).
Now: when installed_plugins.json is present, inject only plugins that are in the
manifest AND enabledPlugins[key]===true, each resolved to its active installPath
(incl. cache/). When the manifest is absent (fixtures/pre-v2 installs), fall back
to the historic marketplaces walk rather than silently dropping config — mirrors
file-discovery.mjs's "trust installed_plugins.json" contract.
Verified on real machine: agent listing 114->104, ghost plugins (newsletter,
content-machine, harness, kiur, ...) gone, voyage/linkedin/ms-ai/okr now correctly
counted. Full suite 1301/0; byte-stable snapshots untouched (hermetic empty HOME).

Completes the deferred B8 half. `--context-window auto` now probes the
configured model and calibrates SKL/CML budgets to its real window instead
of always falling back to the conservative advisory anchor.
- lib/context-window.mjs: pure modelToContextWindow() maps known 1M-tier
model IDs (Fable 5, Opus 4.8/4.7/4.6, Sonnet 4.6 — verified June 2026 —
plus the explicit [1m] tier tag, dated/provider-prefixed IDs, and the
opus/sonnet/fable aliases) to the 1M window; unknown/unconfirmed -> null
(caller keeps the conservative anchor). resolveContextWindow() auto branch
now probes opts.model: recognized -> auto-probed (not advisory); unknown
or unpinned -> auto-unresolved (advisory, pre-B8b behavior).
- lib/active-model.mjs (new): resolveActiveModel() reads the model the way
Claude Code resolves it — shell ANTHROPIC_MODEL override, then settings
cascade local > project > user. Injectable env, hermetic under test HOME.
- scan-orchestrator: resolves the active model only when the flag is `auto`
and threads it into resolveContextWindow; posture inherits via runAllScanners.
Default (no flag) and explicit --context-window <n> paths ignore the model
and stay byte-stable; frozen v5.0.0 + SC-5 snapshots untouched. TDD: 17 new
tests (context-window mapping/probe + active-model cascade). Suite 1296 green.

SKL-002 (skill-listing budget) and CML char-budget now calibrate to a
resolved context window instead of always anchoring at 200k:
- resolveContextWindow(): --context-window <n> calibrates; 'auto' keeps the
conservative 200k anchor but marks advisory (model→window probing deferred
to B8b); no flag → 200k anchor, byte-identical to pre-B8 default.
- scaleForWindow(): linear off the 200k anchor (identity at the anchor).
- SKL + CML each keep an untouched default branch (window===200k && !advisory)
for byte-stability and a calibrated branch; advisory downgrades the budget
finding from a breach (low/medium) to info.
- Flag wired through scan-orchestrator + posture; runAllScanners resolves once
and threads { contextWindow } to scanners (others ignore the 3rd arg).
- CPS intentionally excluded: it has no window-anchored budget (fixed
150-line volatility heuristic), so there is nothing to calibrate.
15 new tests; e2e CLI verified (1M suppresses SKL-002, auto → info, default
unchanged); full suite 1279 green; snapshots byte-stable.

New CA-SKL-003 (low): a SKILL.md body over ~5,000 tokens (~500 lines)
should split reference content into supporting files / use context: fork.
- measureActiveSkillListing() now returns body metrics (chars/lines/tokens);
the body was already read in full, only the frontmatter was parsed before.
- Honest framing: BODY_CALIBRATION_NOTE marks this as ON-DEMAND cost (loads
only when the skill is invoked, NOT every turn like the always-loaded
listing) and an estimate — hence low severity.
- 5 new tests; full suite 1262 green; snapshots byte-stable (default branch
untouched; new finding fires only on bodies >5k tok, none in fixtures).

HKV now flags hooks that build hookSpecificOutput.additionalContext from
un-grepped command output as an INFO advisory (weight 0, never severity-bearing
— excluded from the self-audit nonInfo set). That field enters Claude's context
every time the hook fires (plain stdout on exit 0 does not), so an unfiltered
payload is a recurring per-turn token cost.
- New lib scanners/lib/hook-additional-context.mjs: pure assessHookAdditionalContext
(unit-tested, no IO) + IO wrapper assessHookContextForRepo (walk hooks->scripts).
Heuristic: additionalContext + verbose-prone capture (cat/git log/execSync/…) &&
no filter (grep/head/jq/.slice). Deliberately low precision -> advisory only.
- HKV: emits the advisory inline on scripts it already reads (after the M5 verbose
check). Additive, info severity -> frozen v5.0.0 + SC-5 snapshots untouched.
- feature-gap: new filterHookLeverFinding companion, fires ONLY when >=1 chatty
hook is detected — surfaces the filter-before-Claude-reads lever (CC
filter-test-output.sh). Silent otherwise (opportunity, not noise).
- docs: README HKV + GAP scanner rows; scanner-internals.md HKV row + full B5
implementation note. CLAUDE.md kept lean ([skip-docs]); B5 fully documented in
README + scanner-internals.
Mechanism verified 2026-06-23 against code.claude.com/docs context-window.md

By default Claude Code defers MCP tool schemas (names-only, ~120 tok; full
schemas on demand via tool search). CA-TOK-006 detects config-file signals that
force the FULL schemas into the always-loaded prefix every turn:
- settings.json env.ENABLE_TOOL_SEARCH="false" (high)
- "ToolSearch" in permissions.deny (high)
- configured model is a Haiku model (medium)
- per-server .mcp.json alwaysLoad:true (CC v2.1.121+) (high)
auto[:N] is threshold mode (info, not a trigger).
New engine lib/mcp-deferral.mjs: pure assessMcpDeferral({settings,mcpServers})
(unit-tested, no IO) + thin IO wrapper assessMcpDeferralForRepo shared by TOK and
GAP. Severity scales with aggregate forced-upfront tokens (medium-confidence
reasons cap at medium). feature-gap cliOverMcpLeverFinding fires only as a
companion to CA-TOK-006 (prefer gh/aws/gcloud over MCP for common ops).
Honest scoping (Verifiseringsplikt): triggers on config files ONLY — never
process.env shell vars. Vertex / custom ANTHROPIC_BASE_URL / runtime /model
switch are launch state (would flap snapshots machine-dependently), so they are
DISCLOSED in every finding, not triggered. Tool-level anthropic/alwaysLoad and
claude.ai connectors likewise disclosed. Mechanism verified 2026-06-23 against
code.claude.com/docs (context-window.md, mcp.md#configure-tool-search +
#exempt-a-server-from-deferral, costs.md); the prefix-cache invalidation claim
was NOT-CONFIRMED in docs and is not asserted.
alwaysLoad added to CA-MCP VALID_SERVER_FIELDS (no longer flagged as unknown).
active-config-reader surfaces per-server alwaysLoad. Byte-stable: CA-TOK-006
fires only on new conditions; frozen v5.0.0 + SC-5 snapshots untouched.

The B3a cache filter already exposes discovery.staleCacheVersions; surface them
as a finding so the user knows the superseded plugin versions are safe to delete.
Honesty (Verifiseringsplikt): the finding loads on ZERO turns, so it must NOT
read as a per-turn token cost. TOK normally humanizes to "Wasted tokens"; a new
per-finding category override ('plugin-cache-hygiene' -> "Dead config") plus a
dedicated humanizer translation ("Old plugin versions are sitting on disk (safe
to delete) ... cost zero tokens per turn ... housekeeping, not a performance
problem") keep the prose accurate instead of the generic "using more space"
default. evidence carries the explicit "zero live-context impact" note.
- token-hotspots: Pattern H emits CA-TOK (low) from discovery.staleCacheVersions
when stale versions exist (`--global`); silent otherwise.
- humanizer: CATEGORY_TO_IMPACT lets a finding's category override the
scanner-default impact label (raw `category` field unchanged -> --json/--raw
byte-stable). humanizer-data: honest static translation for the finding.
- Tests: finding fires/severity/category, lists stale keys + zero-impact note,
silent when none; humanizer override -> Dead config; honest translation locked.
- Docs: tokens command render note (disk-cleanup, not a token problem) +
--no-exclude-cache flag; README + CLAUDE.md rows (7 patterns, cache-aware).

Stale ~/.claude/plugins/cache versions polluted token-hotspots ranking and
inflated CNF duplicate-hook findings with config that loads on zero turns.
installPaths point INTO the cache, so a blunt "skip all of plugins/cache"
would drop ACTIVE plugins — the filter is therefore version-aware: it reads
the adjacent installed_plugins.json, keeps active version dirs, drops only
stale ones (and exposes them via discovery.staleCacheVersions for B3b).
- file-discovery: cacheVersionKey() + applyCacheFilter() (active vs stale via
installed_plugins.json; HOME-independent, derives the manifest from the cache
path); discoverConfigFiles/Multi gain { excludeCache } + staleCacheVersions.
Absent/unparseable manifest -> no filtering (never silently drop live config).
- token-hotspots-cli + scan-orchestrator: --exclude-cache (default ON for these
live-cost scans) / --no-exclude-cache restores the full walk.
- Tests: cacheVersionKey unit cases; stale-dropped/active-kept/no-manifest
discovery cases; CNF-drop proof (soft-spot verified, not assumed:
include=1 -> exclude=0 duplicate-hook findings).

Extend the campaign ledger with a machine-wide always-loaded token bill, the
pure data-model + aggregation half of B2. Deliberately does NOT do live I/O:
the cross-repo readActiveConfig sweep that populates real numbers is B2b.
Design — shared layer counted ONCE, structurally:
- Ledger root gets an optional `sharedGlobal` summary (the always-loaded layer
paid in every repo: global CLAUDE.md + agent listing + global MCP + unscoped
global rules + active plugins' always components), stored ONCE via the new
setSharedGlobal().
- Each repo entry gets an optional `tokens` summary (its PER-REPO delta only),
set via the new setRepoTokens(); addRepo now seeds `tokens: null` (mirrors
findingsBySeverity).
- rollUp() stays PURE and gains a `tokens` aggregate: machineWide = sharedGlobal
+ Σ(per-repo deltas), so the shared layer is counted exactly once by
construction — the structural guard against the historic double-count bug.
Plus a `byRepo` table ranked DESC by always-loaded cost ("most expensive
repos") with a deterministic name tie-break.
Summary shape mirrors manifest's summarizeByLoadPattern exactly
({always|onDemand|external|unknown: {tokens,count}}) so B2b wires in trivially.
Keeps rollUp pure (no filesystem I/O) → byte-stable, respects the THIN campaign
motor invariant. Chosen over the plan's literal "run readActiveConfig inside
rollUp" which would break both (operator-approved deviation).
- 8 new ledger tests incl. the counted-once regression guard + byRepo ranking.
- Updated addRepo shape test (+tokens:null) and campaign-cli EMPTY_ROLLUP.
- No frozen snapshot affected (campaign is v5.7, absent from v5.0.0 baselines).
Suite green: 1189 tests.

Flag any single active agent whose description exceeds a 500-char soft cap
(the same bloat threshold TOK pattern F applies to SKILL.md descriptions).
Every char of an agent description re-enters context in the always-loaded
agent listing on every turn, so a long one is a per-turn cost.
Framing is deliberately ADVISORY, severity low: unlike CA-SKL-001 agents
have NO verified per-description cap, so nothing is dropped — this is a bloat
advisory, never a truncation claim. Per-agent advisories are emitted BEFORE
the aggregate roll-up (mirrors SKL 001->002).
- PER_AGENT_DESC_SOFT_CAP (=500) added to lib/agent-listing-budget.mjs as the
single source of truth, disclosed as a heuristic.
- Per-agent loop reuses measureActiveAgentListing()'s agents[] (name, source,
pluginName, path, descLength) — no new enumeration.
- 5 new tests (fire/strict-boundary/no-truncation-claim/recommendation/order).
Byte-stable: AGT already stripped from frozen v5.0.0 baselines; SC-5 unchanged
(HOME-scoped, hermetic HOME has no agents). Suite green: 1181 tests.

New AGT scanner flags the aggregate always-loaded cost of the agent listing
(every active agent's name+description is injected each turn so the model
knows what it can delegate to). Mirrors the SKL skill-listing pattern but
encodes the key honesty caveat: the agent-listing mechanism is INFERRED
(agents are absent from Claude Code's documented context breakdown), so the
token figure is an UPPER-BOUND estimate and the aggregate budget is a
config-audit heuristic anchored on 200k — not a CC-documented allotment.
- scanners/agent-listing-scanner.mjs + scanners/lib/agent-listing-budget.mjs
- 8 TDD tests (tests/scanners/agent-listing-scanner.test.mjs)
- AGT folds into the Token Efficiency health area (scoring.mjs)
- byte-stability: AGT added to strip-added-scanner (frozen v5.0.0 baselines
left untouched, same as OST/OPT); SC-5 default-output snapshot refreshed
- suite 1168 -> 1176 green

Completes Block 4 (4b backlog + 4c export/execution). Asymmetric: plan
export is new testable code; execution is pure reuse of the existing
per-repo implement/rollback (no new execution machinery), per the plan's
"reuse existing backup/rollback".
Plan export ("planer følger arbeidsstedet"):
- scanners/lib/campaign-export.mjs (pure, now injected, 8 tests):
planExportPath(repo,sessionId) -> <repo>/docs/config-audit-plan-<sessionId>.md
(sessionId-keyed so same-day re-audits never collide);
buildPlanExportDocument({...,now}) -> provenance header + verbatim plan.
- scanners/campaign-export-cli.mjs (-cli, read-only by default, 10 tests):
--repo resolves the repo's linked session, reads its action-plan.md,
assembles the doc, emits {exportable,problems,targetPath,document}. Two
gates -> exit 1 advisory: no-session-linked / no-action-plan. Writes the
file ONLY under opt-in --write (byte-faithful copy; the LLM never re-types
a 200-line plan). --sessions-dir override for hermetic tests; exit 0/1/3.
Command: commands/campaign.md gains an `export <path>` mode (Step 6:
preview -> approve -> --write), then routes the user to the existing
/config-audit implement (backup + verify) + rollback + set-status
implemented. Nothing auto-written (Verifiseringsplikt).
Byte-stable: lib + -cli + command-doc only -> scanner count stays 15,
agents 7, commands 21 (export is a mode, not a new command), SC-5 +
backcompat suite untouched. suite 1150->1168. Block 4a (migrateLedger)
still deferred to the first breaking schema change.
Docs: CLAUDE.md section + badge 1150->1168/65->67 files; README badge +
campaign row + Testing prose (fixed stale 1055/59 -> true 1168/67).

Add the durable ledger that sits ABOVE individual config-audit sessions for a
machine-wide audit campaign: repo list + per-repo lifecycle (pending → audited →
planned → implemented) + a machine-wide roll-up by status and severity.
scanners/lib/campaign-ledger.mjs — same hybrid split as knowledge-refresh:
- PURE transforms (createLedger / addRepo / setRepoStatus / rollUp) with `now`
injected (YYYY-MM-DD, never the clock) → deterministic + unit-testable.
- soft validateLedger (returns {valid,errors}, never throws) for loaded data;
transforms throw on programmer error (invalid status, unknown path).
- thin IO shell (defaultLedgerPath / loadLedger→null-on-ENOENT / saveLedger).
- persists to ~/.claude/config-audit/campaign-ledger.json — OUTSIDE the plugin
dir (next to sessions/) so it survives uninstall/reinstall/upgrade.
- schemaVersion stamped from the start → cheap Block 4 migration.
THIN scope (Block 3a, operator-approved): ledger + roll-up + persistence only —
no CLI/command/execution (Blocks 3b/3c/4). Internal plumbing, byte-stable until
consumed: no `export async function scan` + lives in lib/ → scanner count stays
15, no orchestrator wiring, SC-5 unchanged.
tests/lib/campaign-ledger.test.mjs — 28 tests (TDD, red→green). Full hermetic
suite 1091→1119 green.

The 'living' half of the v5.7 living knowledge base. Same hybrid split as the
optimization lens (Chunk 2b): a deterministic, byte-stable, unit-tested core +
a web/judgment command shell.
- scanners/lib/knowledge-refresh.mjs: pure assessFreshness(register,
{referenceDate, staleAfterDays=90}) — age-based fresh/stale classification of
source.verified; referenceDate injected (never reads the clock) → fully
deterministic. 15 tests.
- scanners/knowledge-refresh-cli.mjs: -cli (NOT an orchestrated scanner →
scanner count stays 15, suite byte-stable). Read-only — never writes the
register, never hits the network. --reference-date/--stale-after/--dry-run,
exit 0/1/3. 8 tests.
- commands/knowledge-refresh.md (opus): CLI stale-report → re-verify each stale
entry by re-reading its source.url → poll CC changelog + Anthropic blog →
apply ONLY human-approved writes, then re-validate the register. No unverified
claim is ever auto-written (Verifiseringsplikt). Web-driven → not byte-stable.
No new agent, no new orchestrated scanner. Docs/badges: commands 19→20,
tests 1068→1091 (20 lib + 32 scanner test files). self-audit A/A, readmeCheck passed.

The recall+precision halves of the CA-OPT hybrid motor for the three
mechanism-fit cases the deterministic OPT scanner (2a) deliberately skips:
lifecycle→hook (BP-MECH-001), unscoped path-specific→rule (BP-MECH-002),
absolute "never"→permission (BP-MECH-004).
New:
- scanners/lib/lens-prefilter.mjs — cheap, recall-oriented line scan of the
CLAUDE.md body; detector names mirror the register lensCheck fields; skips
fenced code, gates the path class on an instruction verb. Pure + 13 tests.
- scanners/optimize-lens-cli.mjs — discovery + OPT scanner + pre-filter; attaches
only the CONFIRMED register entry to each candidate (unverifiable → dropped,
Verifiseringsplikt); emits {deterministic, candidates, register, counts}.
- agents/optimization-lens-agent.md — opus precision gate (7th agent, orange):
reads the real CLAUDE.md, drops low-confidence candidates, keeps only genuine
opportunities, cites register id + source.
- commands/optimize.md — /config-audit optimize orchestrates pre-filter→agent→report.
Agent-driven → deliberately NOT byte-stable (own command, outside the snapshot
suite). No new orchestrated scanner → scanner count stays 15. Counts: agents
6→7, commands 18→19, suite 1055→1068. Self-audit A/A unchanged, readmeCheck
passed (clean HOME). Plan: docs/v5.7-optimization-lens-plan.md.

First detector of the 'is the config OPTIMAL?' axis (vs the existing 'correct?' scanners). New orchestrated scanner family CA-OPT (count 14->15), the deterministic half of the hybrid optimization lens.
CA-OPT-001 (low, Missed opportunity): a multi-step procedure in CLAUDE.md (>=6 consecutive numbered steps) that belongs in a skill. Reads recommendation + provenance from the best-practices register (BP-MECH-003). Conservative by design; the negative corpus proves null false-positives. Prose-judgment cases (lifecycle->hook, 'never'->permission) are deferred to the Chunk 2b opus analyzer.
Wiring mirrors OST: orchestrator entry, humanizer (OPT->'Missed opportunity' + family), scoring (OPT->'CLAUDE.md', existing area -> no new posture row -> byte-stable), strip-helper (OST,OPT), SC-5 regenerated under hermetic HOME (additive OPT entry only). 10 new tests; suite 1045->1055, self-audit A/A, readmeCheck passed (all verified with a clean HOME).
Note: the pre-existing TOK test reads the real ~/.claude (non-hermetic) -> run the suite with a clean HOME for deterministic results. Tracked as a separate follow-up.

Add knowledge/best-practices.json: a machine-readable, provenance-stamped, schema-validated best-practices register — the source of truth for the upcoming v5.7 optimization lens (CA-OPT). 13 seed entries migrated from the v5.5 V-rows (loading-model + compaction facts) and the Anthropic 'Steering Claude Code' blog (mechanism-fit rules); each entry carries source.url + verified date + confidence. Only confirmed claims are user-facing (Verifiseringsplikt).
scanners/lib/best-practices-register.mjs: zero-dependency loader + validator (loadRegister/validateRegister/getEntry, native JSON.parse — not YAML, since the repo is zero-dep and yaml-parser.mjs can't parse arrays-of-objects). tests/lib/best-practices-register.test.mjs: 22 tests (schema, provenance integrity, negative cases, lookup).
Byte-stable: no scanner consumes the register yet (Chunk 2), so all scanner output is unchanged. Suite 1023->1045, self-audit A/A, readmeCheck passed. Full design: docs/v5.7-optimization-lens-plan.md.

New orchestrated scanner output-style-scanner.mjs — first new family since
SKL. Three findings, each pinned to a CONFIRMED V-row of the steering-model
plan + re-verified against code.claude.com/docs/en/output-styles:
- CA-OST-001 (medium, V10): user/project custom style missing
keep-coding-instructions:true (default false) → silently strips built-in
software-engineering instructions when active. Scoped to user/project.
- CA-OST-002 (low, V11): plugin style with force-for-plugin:true overrides the
user's selected outputStyle. Verifiseringsplikt correction — the plan bullet
said "project/user style," but force-for-plugin is plugin-styles-only per the
docs, so the check keys on source==='plugin'.
- CA-OST-003 (medium): settings outputStyle matching no built-in
(Default/Explanatory/Learning/Proactive, case-insensitive) nor discovered
custom style → dead config.
Byte-stability — a scanner addition, not a field addition. Growing the
scanners array + scanners_ok cannot be hidden by a field strip, but re-seeding
frozen v5.0.0 (the SKL precedent) would now bake in B2's hotspot triple +
claudeMd drift. So, per the B2 lesson, frozen v5.0.0 snapshots are PRESERVED
and the OST entry is stripped at compare time via new
tests/helpers/strip-added-scanner.mjs (wired into json/raw-backcompat + the
Step 5/6 humanizer tests); only SC-5 default-output is regenerated (additive
OST entry, diff reviewed). OST is fixture-gated (no output styles on
marketplace-medium / hermetic HOME → silent).
Wiring: orchestrator; humanizer (OST→Configuration mistake) + humanizer-data
OST family (title-coupled); scoring (OST→Settings, keeps 10 areas). Suite
1012→1023 (+11). Badges: scanners 14, tests 1023, TRANSLATIONS families 15.

Annotate every ranked TOK hotspot with the load-pattern triple
(loadPattern/survivesCompaction/derivationConfidence):
- hotspotLoadPattern() maps each discovery `type` → a deriveLoadPattern kind.
Rules reuse activeConfig.rules for precise `scoped` handling; claude-md maps
by scope. Two new deriveLoadPattern kinds back the rest: `command`
(on-demand — body loads on /invoke) and `harness-config` (external —
settings/keybindings/.mcp.json/hooks.json/plugin.json configure the CLI, not
the model context, so they cost no per-turn context tokens). Honest split:
the .mcp.json FILE is external; the MCP server's tool schemas are a separate
`always` hotspot.
Byte-stability — the opposite of B1's manifest. token-hotspots IS a byte-equal
SC-6/SC-7 CLI, and its hotspots ride inside scan-orchestrator + posture, so the
change touched SIX frozen-v5.0.0 comparisons across five test files. Resolved by
preserving the frozen baselines: a shared tests/helpers/strip-hotspot-load-pattern.mjs
strips the additive triple before each byte-equal compare (proves the original
schema is byte-identical). SC-5 default-output snapshots (scan-orchestrator +
token-hotspots) regenerated — diff reviewed as additive-only.
Tests 1008→1012. Self-audit A/A, scanner count unchanged at 13 (C bumps to 14).
Completes v5.6 B (B1 manifest + B2 token-hotspots).

Foundation chunk of v5.6 "steering-model II" (internal plumbing for B/C;
no command-output change, so --json/--raw/SC-5/6/7 stay byte-stable, count
stays 13).
active-config-reader.mjs:
- deriveLoadPattern(kind,{scoped}) — pure helper mapping each source kind to
loadPattern {always,on-demand,external} + survivesCompaction {yes,no,n/a}
+ derivationConfidence {confirmed,inferred}, traced to the published
loading model (V-rows in docs/v5.5-steering-model-plan.md).
- enumerateRules / enumerateAgents / enumerateOutputStyles — the three
source kinds previously unenumerated (mirror enumerateSkills). Output-style
discovery is direct (not a new file-discovery type) to keep the discovery
surface stable.
- readActiveConfig now exposes rules/agents/outputStyles arrays + totals
counts/subtotals (folded into grandTotal).
yaml-parser.mjs:
- parseSimpleYaml now reads YAML block sequences (paths:\n - a), not just
inline paths:. An empty-valued key with no `- ` items stays null
(backcompat). Resolves a pre-existing RUL false-positive (a block-seq-scoped
rule was misread as unscoped) — fix flows through unchanged RUL code.
Tests +35 (961 -> 996): block-seq parser cases, RUL block-seq regression
(no-misflag + durability-fires), deriveLoadPattern table, three enumerators
(positive+negative). Amended two existing ACR asserts (top-level key shape +
grandTotal sum). self-audit A/A, readmeCheck passed, mismatches []. tests
badge 961+->996+; README testing prose de-staled (635/36 -> 996/56);
CLAUDE.md Foundation note.
B (manifest/tokens render + snapshot regen) and C (CA-OST, count->14)
deferred to their own sessions/GO.

Per the official "what survives compaction" model (context-window.md):
only the project-root CLAUDE.md (+ unscoped rules) is re-injected after a
context compaction. Two additive, structural findings (low severity):
- RUL: a large (>50-line) PATH-SCOPED rule — reloads only on a matching
file read, and is not re-injected after compaction, so must-hold rules
can silently drop mid-session.
- CML: a NESTED (subdirectory) CLAUDE.md — not re-injected after
compaction (only the project root is).
Additive (no new scanner, count stays 13); one humanizer entry each;
hermetic temp-fixture tests (positive + negative). Suite 957 -> 961,
SC-5 byte-stable, self-audit A/A.
Known limitation (pre-existing, broader than A): the lightweight
frontmatter parser reads inline `paths:` but not YAML block sequences,
so block-sequence-scoped rules are still seen as unscoped. Deferred.
Part of v5.5.0 "steering-model I". Foundation (active-config-reader
enumeration) deferred to v5.6 with B.

Plugin subagents silently ignore `hooks`/`mcpServers`/`permissionMode`
frontmatter — these are honored only for user/project agents in
.claude/agents/ (code.claude.com/docs sub-agents). Setting them in a
plugin agent is dead config; `permissionMode` is MEDIUM because it
implies a restriction Claude Code does not apply (false security).
hooks/mcpServers are LOW.
Additive to PLH's agent-frontmatter loop (no new scanner, count stays
13). One humanizer pattern covers the three field titles. Hermetic
temp-fixture test (positive + negative). Suite 954 -> 957, byte-stable.
Part of v5.5.0 "steering-model I". Foundation (active-config-reader

HKV: add Setup, UserPromptExpansion, PostToolBatch to VALID_EVENTS,
verified live against code.claude.com/docs/en/hooks.md (2026-06-19). A
valid hook using one of these was wrongly flagged "will never fire" — a
user could delete a working hook. Made the "(N total)" hint dynamic so
it can't drift again. Flagged the unverified kebab 'post-session' in a
comment (an existing test depends on it; follow-up check needed).
RUL: reword the globs finding. Only `paths:` is documented; whether CC
ever read `globs` is unverified, so the old "deprecated/legacy" framing
overclaimed (Verifiseringsplikt). New wording steers to the documented
`paths:` field. Updated the coupled fix-engine title match and the
humanizer entry (which also carried the "field was renamed" overclaim).
Suite 950 -> 954 (badge bumped). self-audit A/A, scanner count 13. No
version bump — these land in the pending v5.4.1 patch.

settings-validator now validates the autoMode block (auto-mode classifier
config). Structure (medium): autoMode must be an object whose only keys are
environment/allow/soft_deny/hard_deny, each a string array ("$defaults" is a
valid entry); flags not-an-object, unknown-subkey, not-string-array. Dead-config
(low): Claude Code does not read autoMode from shared project settings
(.claude/settings.json), so an autoMode block committed there has no effect —
keyed on file.scope === 'project'.
Both premises primary-source-verified (code.claude.com/docs/en/auto-mode-config).
The plan's "test per-file scope first" gate passed: ConfigFile already carries
scope. SET is in the orchestrator; SC-5 re-checked, byte-equal (snapshot fixture
has no autoMode). Fixtures force-added (.claude/ is gitignored).
Tests +5 (944->949). Scanner count unchanged (13). --json/--raw byte-stable.

PLH now validates each entry of a plugin.json `skills` field (string|array):
every entry must resolve to an existing directory inside the plugin root.
One finding per bad entry (medium, plugin-hygiene), problem ∈ {non-string,
escapes-root, not-found, not-a-directory}. Mirrors `claude plugin validate`.
String|array normalized so a non-string top-level value is caught too.
Verifiseringsplikt: the plan's "CC suggests the parent directory" error text
is NOT in the primary docs — dropped. Only the four primary-source-verified
conditions are asserted (escape backed by the path-traversal rule).
Tests +3 (941->944). Scanner count unchanged (13). --json/--raw byte-stable.

PLH now flags a plugin.json component-path key (commands/agents/outputStyles)
that replaces a default folder still present on disk — Claude Code stops
scanning that folder, so its contents are silently ignored (dead config).
Mirrors CC's /doctor & `claude plugin list` warning (v2.1.140+).
Field set pinned to the docs' "replaces" category only (Verifiseringsplikt,
code.claude.com/docs path-behavior-rules): skills is excluded (adds to the
default skills/ scan — both load) as are hooks/mcpServers/lspServers (own
merge rules); a custom path that addresses the default folder is not flagged.
Tests +5 (936->941). Scanner count unchanged (13). --json/--raw byte-stable.

Commands are namespaced (/name:command), so a command name shared by two
differently-named plugins keeps both reachable — it is ambiguity, not a hard
conflict. The check now mirrors COL's plugin-vs-plugin skill finding: severity
LOW (was HIGH), category plugin-hygiene, COL-shaped details.namespaces, and a
group-first shape (one finding per command name listing every namespace, not
pairwise). It keys on the declared namespace (was folder basename) and fires
only across 2+ distinct namespaces — when plugins share a declared name, the
namespace-collision finding (medium) is the right signal, so this stays silent.
Removes the inaccurate "only one wins" humanizer entry. Adds fixtures
(duplicate-command-name; a shared command in duplicate-plugin-name's colliding
namespace) and 4 tests. Suite 932->936. self-audit A 97 / A 100, scanners 13.
Two plugins that declare the same `name` in plugin.json collapse into one
component namespace (/name:command, name:skill, agent "name"). Resolution
between two installed same-name plugins is undocumented, so one plugin's
commands/skills/agents are silently shadowed and unreachable. PLH now flags
this at medium severity, keying on the declared `name` (not folder basename,
via new declaredName on scanSinglePlugin) with a COL-shaped details.namespaces
payload. Name-less plugins are excluded from the collision map.
Search-first (code.claude.com/docs/en/plugins): plugin components are
namespaced by the declared name, so a plugin component can never shadow a
user/project one — only a same-name collision loses components. This refutes
the original "plugin vs user vs project shadowing" framing in the backlog.
Adds humanizer pattern, fixture (duplicate-plugin-name: 2 colliding + 2
name-less), and 3 tests. Suite 929->932. self-audit A 97 / A 100, scanners 13.
Extends the DIS scanner and its shared permission-rules lib with a third
documented Claude Code permission footgun. Verified verbatim against
code.claude.com/docs/en/permissions (fetched 2026-06-19).
CC's Tool(param:value) matching (2.1.178) is off-limits for a tool's own
canonicalizing field — CC ignores such a rule and emits a startup warning,
because e.g. Bash(command:rm *) is bypassable by a compound command. The
forbidden fields: command (Bash/PowerShell), file_path (Read/Edit/Write),
path (Grep/Glob), notebook_path (NotebookEdit), url (WebFetch).
- lib/permission-rules.mjs: new forbiddenParamRule(entry) returning
{ tool, key, hint } or null. Only the param:value form (colon present)
whose key equals the tool's forbidden field is flagged; Bash(npm:*),
WebFetch(domain:host), Agent(model:opus), and Bash(command) (no colon)
are left valid. FORBIDDEN_PARAMS map is the single source of truth.
- DIS: scans allow + deny + ask and splits severity by intent — deny/ask
hits are false security (medium: the block never applies), allow hits are
dead config (low: param:value matching is deny/ask-only). Two findings,
permissions-hygiene, CA-DIS-NNN.
- 11 new tests (7 lib, 4 DIS) + 1 fixture forbidden-param-permissions
(force-added past .gitignore .claude/). Suite 918 -> 929. Snapshot
unchanged (SC-5 byte-equal), contamination grep clean, gitleaks clean.

Add a char-based CML finding that mirrors Claude Code's own startup warning
("Large CLAUDE.md will impact performance (X chars > 40.0k)"). CC 2.1.169 scales
that threshold with the model's context window, so the finding anchors on the
conservative 200k window (we cannot observe the user's window; the anchor fires
earliest) and discloses the relaxed ~200,000-char figure at 1M context. MEDIUM
severity (token cost, not an adherence cliff — consistent with the v5.2.0 reframe).
Keyed on chars, not lines, so it is complementary to the existing 200/500-line
checks (which stay untouched): a file can be long by lines yet under budget (short
lines, e.g. large-cascade at 37k chars / 1024 lines), or short by lines yet over it.
Extract the shared 200k/1M context-window constants to scanners/lib/context-window.mjs
(single source of truth; skill-listing-budget.mjs now imports + re-exports them).
40.0k figure and context-window scaling verified against the CC changelog (2.1.169,
2026-06-08) and the live startup-warning text. +6 tests, new fixture large-claude-chars
(48,531 chars / 100 lines). Suite 918/918, self-audit PASS configGrade A 97.

Extends the DIS scanner and its shared permission-rules lib with two
documented Claude Code permission footguns. Verified verbatim against
code.claude.com/docs/en/permissions (fetched 2026-06-19).
- lib/permission-rules.mjs: new isIneffectiveAllowGlob(entry) — unanchored
tool-name globs in permissions.allow (`*`, `B*`, `mcp__*`) that CC silently
skips ("does not auto-approve anything"); valid only as a glob-free
`mcp__<server>__*`. Shared with CNF.
- lib/permission-rules.mjs: dominates() now treats the `Tool(*)` deny-all glob
as equivalent to a bare deny (covers a bare allow) — CC: "Bash(*) is
equivalent to Bash ... both forms remove the tool from Claude's context".
- DIS: new finding "Ineffective allow wildcard — Claude Code ignores this rule"
(low, permissions-hygiene, CA-DIS-NNN); the existing dead-allow finding now
also catches a bare allow killed by a Tool(*) deny.
- 9 new tests (5 lib, 4 DIS) + 2 fixtures (force-added past .gitignore .claude/).
Suite 903 -> 912. Snapshot unchanged, contamination grep clean. README/CLAUDE/
scanner-internals document the broadened DIS mandate; test badge synced.

Chunk 2 of the disableBundledSkills GAP feature. Adds a conditional GAP check
that prescribes the `disableBundledSkills` lever — but only when the active
skill listing is measurably over budget (SKL's CA-SKL-002 overflow signal) and
the lever is un-pulled. It stays an opportunity, not noise.
Bundled skills (/code-review, /batch, /debug, /loop, /claude-api, …) live in the
CC binary, not on disk, so their exact cost is unmeasurable here — the finding
says so plainly, and frames the lever as zero-cost budget reclaim that leaves
the user's own skills untouched. CC 2.1.169+.
- Pure, exported bundledSkillsLeverFinding({leverPulled, aggregate}) → finding|null
(severity low, category token-efficiency, CA-GAP-NNN), wired into scan() via the
shared measureActiveSkillListing().
- Lever resolved via new isBundledSkillsDisabled(): env var + settings cascade
read directly, because discovery does NOT tag ~/.claude/settings.json (its
relPath lacks ".claude" when walked from the .claude root) — the dominant
user-scope location for this global preference would otherwise be missed.
- GAP scan() now reads HOME → existing GAP tests retrofitted to withHermeticHome
per the hermetic rule. Snapshots unchanged, contamination grep clean.
- 16 new tests (9 GAP, 7 lib). Suite 887 -> 903. README/CLAUDE.md document the
cross-scanner remediation; test counts synced. self-audit: PASS, configGrade
A 96, pluginGrade A 100, readme gate passed.

Chunk 1 of the disableBundledSkills GAP feature. Moves the per-description cap,
aggregate budget constants, calibration note, and the enumerate-and-measure step
out of skill-listing-scanner into scanners/lib/skill-listing-budget.mjs — so SKL
(diagnoses overflow) and the upcoming GAP check (prescribes disableBundledSkills)
consume one budget definition instead of two divergent copies.
- New lib: assessSkillListingBudget (pure aggregate math) + measureActiveSkillListing
(HOME-scoped enumerate-and-measure wrapper).
- SKL delegates measurement; all finding strings kept byte-identical. 18/18 SKL
tests pass unchanged → behavior-neutral refactor.
- 12 new lib unit tests pin the budget contract. Suite 875 -> 887.
- README badge + CLAUDE.md test counts synced (self-audit --check-readme: passed).

Syklus 2 of Fase 4 Items 2+3. Flags when the sum of active skill
descriptions exceeds the listing budget (~2% of context, CC 2.1.32).
Design (operator-confirmed "fact-first, 200k anchor"):
- low severity (estimate) vs medium for the verified 1,536-char cap
- each description counted up to the 1,536 cap (what actually loads in
the listing) — avoids double-counting the tail CA-SKL-001 flags
- fires when sum > 2% x 200k = 4000 tok; evidence leads with the measured
sum + a calibration note that the budget scales 5x on 1M-context models
- aggregate emitted after the per-skill loop so the common case reads
001=cap, 002=aggregate (finding IDs are a sequential counter, not stable
semantic IDs — tests match on title, never NNN)
Also:
- tailored humanizer static entry for the aggregate title
- fix latent HOME leak in posture-grade-stability.test.mjs: it spawned
posture.mjs without hermeticEnv(), so a real ~/.claude leaked HOME-scoped
SKL/COL findings into the baseline grade (Token Efficiency A->B). Now
isolated like the 8 other CLI-spawning tests.
- docs sync: test count 868->875, scanner-internals, gap-matrix, plan status
Suite 875/875, no snapshot drift, self-audit clean.

Fase 4 Items 2+3 (CC 2.1.114→181 gap-review). New orchestrated scanner
`skill-listing-scanner.mjs` (prefix SKL) flags every active skill whose
description exceeds the verified 1,536-char listing cap (CC 2.1.105, changelog
L1502). Past the cap, Claude Code silently truncates the description the model
reads to route skill invocation — dropping the trigger phrases at the tail.
HOME-scoped over all user + plugin skills via enumerateSkills (COL is the model).
- CA-SKL-001 (medium): description > 1,536 chars. Remediation folds in Item
2(b) — recommends disableBundledSkills + skillOverrides + trimming
(designvalg A: no standalone GAP-check, which would fire for nearly everyone).
- Designvalg B: v1 ships the verified cap ONLY. The aggregate 2%-of-context
listing budget is deferred — it needs a context-window assumption that would
turn a verified fact into a guess (would carry a CALIBRATION_NOTE if added).
- Choice C: recognize the skillOverrides settings key (CC 2.1.129) in
KNOWN_KEYS. Left OUT of TYPE_CHECKS — the value is a per-skill object
(off/user-invocable-only/name-only), not a string; a 'string' check (as the
plan sketched) would create a NEW false positive. Verify-first deviation.
Registration: scan-orchestrator (13th scanner), humanizer (SKL → 'Wasted
tokens' + static/_default translations), scoring SCANNER_AREA_MAP (→ Token
Efficiency; no 11th area), README badge 12→13, CLAUDE.md (finding-id +
test-count), docs/scanner-internals.md, gap-matrix + plan status notes.
Snapshots reseeded hermetically (SEED_SNAPSHOT/UPDATE_SNAPSHOT): SKL entry with
0 findings in empty HOME, scanners_ok 11→12, claudeMdEstimatedTokens bump from
the CLAUDE.md edits flowing through the cascade. Contamination grep clean.
Suite 868/868 (856 baseline + 11 SKL + 1 skillOverrides). RED→GREEN logged

`.mcp.json` has no per-server `trust` key — verified 2026-06-18 against
code.claude.com/docs/en/mcp + /settings. MCP server approval is
dialog/settings-based (enableAllProjectMcpServers / enabledMcpjsonServers /
disabledMcpjsonServers), never a JSON field. The scanner's "Missing trust
level" (CA-MCP-001, medium) and "Invalid trust level" (high) were false
positives flagging a field that does not exist.
- scanner: delete both trust checks + VALID_TRUST_LEVELS; drop `trust` from
VALID_SERVER_FIELDS so a stray `trust` is now flagged as an unknown field
- humanizer: remove the two trust-level entries
- knowledge (5 files): point to the real approval mechanism, not a trust field
- fixtures: scrub `trust` (incl. the invalid "local" in optimal-setup)
- tests: flip assertions (no trust-level finding; stray trust -> unknown
field) + add knowledge-staleness re-freeze guards
- snapshots: reseed (marketplace-medium .mcp.json -8 tokens, hermetic)
- gap-matrix: mark the trust verify-first item DONE

The DIS scanner collapsed Tool(param) rules to the bare tool name, so
Agent(model:opus) deny + Agent(model:sonnet) allow (and the same for
WebFetch(domain:...)) were flagged as dead config — a false positive now
that CC 2.1.178 matches Tool(param:value) and 2.1.172 adds domain rules.
The conflict-detector shared the blind spot from the other side: a
wildcard deny like WebFetch(domain:*) did not cover a
WebFetch(domain:good.com) allow, so a genuine cross-scope conflict was
missed (false negative).
New shared scanners/lib/permission-rules.mjs:
- parseRule / paramMatches (glob)
- dominates(deny, allow) -> DIS dead-allow (deny fully covers allow)
- rulesIntersect(a, b) -> CNF cross-scope conflict (match sets intersect)
DIS now delegates to dominates; conflict-detector :156 delegates to
rulesIntersect. A bare deny still covers all params, so true positives
are preserved (Bash deny + Bash(npm:*) allow still flagged).
Re-seeded the marketplace-medium snapshots: the false-positive CA-DIS
finding (Read(src/**) allow + Read(./.env) deny) is correctly gone. This
changes snapshot CONTENT only — envelope schema is unchanged, so --json
and --raw stay byte-stable.
Full suite: 837/837 green (+25). self-audit PASS, A(100)/A(97).
Step 8 of v5.1.0 humanizer Wave 4. Adds tests/lint-default-output.mjs
runner and tests/scanners/lint-default-output.test.mjs wrapper that
exercise SC-3 against the 6 prose CLIs (scan-orchestrator, posture,
token-hotspots-cli, plugin-health-scanner, drift-cli, fix-cli) running
in default (humanized) mode against tests/fixtures/marketplace-medium.
Lint scope is stderr only — JSON envelope keys ("scanner", "severity")
are structural, not prose. Humanized prose fields embedded inside JSON
are already covered by tests/lib/humanizer-data.test.mjs tier1/tier3
checks. Code references inside backticks pass the lint
(stripBacktickSpans) so technical identifiers can appear when wrapped.
Default-mode prose fixes to land lint at zero violations:
- scan-orchestrator: top banner switches to "Config-Audit v2.2.0" and
per-scanner progress wraps "[XXX] Label" in backticks. --raw and
--json paths preserve the v5.0.0 verbatim banner via new
opts.humanizedProgress flag on runAllScanners.
- plugin-health-scanner: top banner switches to "Plugin Health v2.1.0"
in default mode; --raw/--json keep "Plugin Health Scanner v2.1.0".
- scoring.mjs generateHealthScorecard humanized branch: area names
(CLAUDE.md, Hooks, MCP, Settings, Rules, Imports, Conflicts, Token
Efficiency, Plugin Hygiene) are wrapped in backticks; dot-padding
compensates so column alignment matches v5.0.0 layout.
- posture / drift-cli / fix-cli: thread humanizedProgress flag through
their runAllScanners calls so default mode emits humanized progress
and --raw/--json preserve the v5.0.0 stderr snapshot.
Test infrastructure only — user-facing docs land in Wave 5/6 once
commands and agents consume the humanized payload.
Tests: 735 to 736 (+1 SC-3 wrapper). Full suite passes.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
generateHealthScorecard signature: 2-arg → 3-arg (areaScores, opportunityCount,
options = {}). options.humanized=true renders friendlier title, grade-context
line per overall grade, and rephrased opportunity line. options.humanized=false
(or 2-arg call) preserves v5.0.0 verbatim output for backwards-compat.
topActions also gets an optional options.humanized that swaps recommendations
through humanizeFinding lookup.
posture.mjs main():
--json → write JSON to stdout, suppress stderr scorecard
--raw → write JSON to stdout (byte-identical to --json), write v5.0.0
verbatim scorecard to stderr
default → humanized scorecard to stderr, no stdout
posture.test.mjs scorecard-prose assertions re-anchored to --raw mode (the
explicit v5.0.0 path) — Wave 0 audit only covered finding-title strings;
scorecard prose surfaces here for the first time.
Wave 3 / Step 6 of v5.1.0 humanizer.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Wave 1 / Step 3 of v5.1.0 plain-language UX humanizer.
scanners/lib/humanizer.mjs exports three pure functions:
- humanizeFinding(f) -> new finding object with translated
title/description/recommendation + three new fields
(userImpactCategory, userActionLanguage, relevanceContext).
- humanizeFindings(findings) -> mapped array.
- humanizeEnvelope(env) -> walks env.scanners[].findings.
Plus computeRelevanceContext(filePath) as a named export for
unit testing.
Field semantics:
- userImpactCategory: from scanner prefix per research/02 line 124
(Configuration mistake / Conflict / Wasted tokens / Dead config /
Missed opportunity / Other).
- userActionLanguage: from severity per research/02 line 134
(Fix this now / Fix soon / Fix when convenient / Optional cleanup
/ FYI).
- relevanceContext: deterministic file-path heuristic — looks for
/tests/fixtures/ or /test/fixtures/ substring (test-fixture-no-impact),
*.local.* basename (affects-this-machine-only), defaults to
affects-everyone. No subprocess, no network.
Lookup order per scanner: static[title] -> patterns regex match ->
_default -> fall through to original strings (when scanner prefix
absent).
Original id, scanner, severity, file, line, evidence, category,
autoFixable, and optional details are preserved exactly. Pure —
verified by deepEqual of input before/after.
Test (32 cases): purity, field preservation across all paths,
known/unknown scanner handling, all 5 severities, all 6 categories,
relevance heuristic for 4 path types, envelope walking, ANSI-free
guarantee. All pass.
Regression: 689/689 tests (657 + 32 new = 54 new across Wave 1).

Wave 1 / Step 2 of v5.1.0 plain-language UX humanizer.
scanners/lib/humanizer-data.mjs exports TRANSLATIONS keyed by
scanner prefix (CML, SET, HKV, RUL, MCP, IMP, CNF, GAP, TOK, CPS,
DIS, COL, PLH). Each scanner has:
- static: exact-title -> {title, description, recommendation}
- patterns: array of {regex, translation} for template-literal titles
- _default: graceful fallback for unknown findings
Architectural change vs. plan: keys translations by exact scanner
title (not finding ID). Reason: finding IDs are sequence-based
(global counter in lib/output.mjs:34), not stable per finding-type
— two runs can produce different IDs for the same logical issue.
Title strings ARE stable (defined as string literals or template
patterns in the scanner source).
Translations follow research/03 SR-1..SR-17:
- active voice, second person, present tense
- sentences <= 25 words
- tier1 absolute prohibitions and tier3 domain jargon are kept out
of prose
- tier1/tier3 terms are permitted inside `backtick spans` (code
references like filenames and field names) — established
technical-doc convention
Test (12 cases): all 13 scanners covered; every static and pattern
entry has the 3 required fields; tier1 and tier3 forbidden-word
checks pass (with backtick-span exclusion); reference-stable
imports. All pass.
Regression: 657/657 tests (645 + 12 new).

New COL scanner detects skill-name collisions across plugins and
between user-level skills (~/.claude/skills/) and plugin-bundled
skills. Skill identity is the directory basename — matches how
enumerateSkills resolves names.
Detection rules (per docs/v5-namespace-research.md, confidence: medium):
- Plugin-vs-plugin same skill name → severity low (CA-COL-001)
- User-vs-plugin same skill name → severity medium (CA-COL-001)
- Plugin-vs-built-in collisions: out of scope for v5.0.0 (insufficient
verification — recorded for v5.0.1 follow-up).
Findings carry details.namespaces array with {source, name, path} for
every conflicting source — supports per-collision reporting downstream.
output.mjs: finding() helper now passes through optional `details`
field (scanner-specific structured payload).
scoring.mjs: COL → "Plugin Hygiene" (new area, 10 total). Posture test
updated from 9 → 10 area scores.
.gitignore: docs/v5-namespace-research.md is local-only (Step 22a
research output, gitignored per plan).
Fixture collision-plugins/fake-home/ has user skill `review` colliding
with plugin-a + plugin-b's `review` (medium severity), plus plugin-c's
unique `summarize` (no collision).

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.

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.
