The COL collision-scanner and the CLAUDE.md cascade resolve ~/.claude from
process.env.HOME (active-config-reader). Snapshot/byte CLIs were spawned with
the developer's real HOME, so they picked up installed plugins/skills and the
user CLAUDE.md — making the v5.0.0 + default-output snapshots machine- and
time-dependent. They were seeded 2026-05-01 with COL=1 (a real ~/.claude skill
collision) and drifted to COL=0 after the polyrepo split: 26 pre-existing
failures unrelated to Batch 1.
Fix (test-only, no production change):
- tests/helpers/hermetic-home.mjs — empty temp HOME, mirroring the pattern
collision.test.mjs already uses for the COL unit test.
- 7 harnesses spawn CLIs (or call lint()) under the hermetic HOME, so output
depends only on committed fixtures. Determinism verified across runs.
- Re-seeded all snapshots under hermetic HOME via SEED_SNAPSHOT/UPDATE_SNAPSHOT
(added a SEED guard to the frozen v5.0.0 byte tests). Snapshots now reflect
the fixture alone (COL=0, fixture-only activeConfig counts).
- Also re-seeded the unused env-aware snapshots (manifest/whats-active/
plugin-health), which had baked dozens of real ~/.claude skill/plugin names
into the committed repo — privacy cleanup.
Full suite: 812/812 green, stable across 3 runs.
- Plugin README: add "What's New in v5.1.0" section with humanizer overview,
before/after example, plain-language vocabulary table, --raw flag docs.
Bump version badge 5.0.0 → 5.1.0. Add Version History row.
- Plugin CLAUDE.md: add humanizer.mjs + humanizer-data.mjs to Scanner Lib
table. Add "Plain-Language Output (v5.1.0)" section documenting output
modes, vocabularies, and Wave 5 lessons. Bump test count 635 → 792 across
52 test files.
- Marketplace root README: bump config-audit entry 5.0.0 → 5.1.0, update
one-line description to mention plain-language UX, add bullet for the
v5.1.0 humanizer, bump test count 635+ → 792+.
Test-normalizer hardening (consequence of growing CLAUDE.md):
walkClaudeMdCascade walks upward from the marketplace-medium fixture into
this plugin's own CLAUDE.md, so any docs edit ripples into
`scanners[*].activeConfig.claudeMdEstimatedTokens`. The v5.0.0 byte-stability
contract is about scanner internals being unchanged, not ancestor input
content being frozen. Normalizers in json-backcompat, raw-backcompat,
posture-humanizer, scan-orchestrator-humanizer, and snapshot-default-output
now strip claudeMdEstimatedTokens to <ANCESTOR_DERIVED>. The
default-output snapshot for scan-orchestrator was re-seeded via
UPDATE_SNAPSHOT=1 (intent: Wave 6 docs additions; humanizer prose
unchanged).
Verify:
- grep -E "5\.1\.0|v5\.1\.0" README.md CLAUDE.md ../../README.md | wc -l = 12
- node --test 'tests/**/*.test.mjs' = 792/792 pass
- self-audit configGrade A (97), pluginGrade A (100), readmeCheck.passed true
Step 10 of v5.1.0 humanizer Wave 4. Adds tests/json-backcompat.test.mjs
asserting that --json output of every CLI remains backwards-compatible
with the v5.0.0 contract.
Coverage strategy mirrors Wave 3 cli-humanizer test discovery:
- 4 fixture-deterministic CLIs (scan-orchestrator, posture,
token-hotspots-cli, fix-cli) get strict byte-equal byte-equal --json
vs frozen tests/snapshots/v5.0.0/ snapshot, with time-varying fields
(timestamp, target path, duration_ms, generatedAt, durationMs)
normalized.
- drift-cli is checked with the same byte-equal contract guarded by an
ensureDriftBaseline precondition; the test silently skips when the
baseline cannot be created.
- 3 environment-aware CLIs (plugin-health-scanner, manifest,
whats-active) read live config-cascade state, so frozen snapshots
drift as the marketplace evolves. They are verified by mode-
equivalence (--json equals --raw) instead — the same approach
established in Wave 3 cli-humanizer.test.mjs.
A cross-cutting suite asserts --json output of the 4 deterministic
CLIs never carries humanizer fields (userImpactCategory,
userActionLanguage, relevanceContext) on any finding, walking both
top-level findings arrays and scanners[].findings paths.
Tests: 739 to 751 (+12 SC-6 cases). Full suite passes.
