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.
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.
