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.
Wave 0 / Step 0 of the v5.1.0 plain-language UX humanizer plan.
Captures v5.0.0 baseline output for all 8 CLIs at
tests/snapshots/v5.0.0/ — these snapshots are immutable references
for SC-6 (--json byte-equal) and SC-7 (--raw byte-equal) tests in
later waves.
- 5 CLIs captured via --output-file: scan-orchestrator, posture,
token-hotspots-cli, manifest, whats-active
- 3 CLIs captured via stdout redirect (no --output-file support):
drift-cli (after baseline seed), fix-cli, plugin-health-scanner
- Posture stderr scorecard captured separately for SC-7 stderr-mode
comparison
docs/v5.1.0-test-audit.md classifies all 42 .title references in
7 known test files: 34 will break under humanization (literal
string equality / substring), 8 are safe (test fixtures or error
formatting). This document is the change list for Step 4.
