Touchfiles + E2E tiers gain the Aside keys, coverage matrix and eval baselines updated, size budget re-baselined to parity-baseline-v1.80.0.0.json (the contract plus fallback ride in every browsing skill), parity ceilings ratcheted with measured values, LLM-judge prompts and the E2E fixtures speak Aside-first, browse-fallback.

/**
|
|
* No module-scope GSTACK_HOME assignment in any test file.
|
|
*
|
|
* Shard processes evaluate many test-file modules in one bun process, and a
|
|
* module can be loaded before its tests run — so a module-scope
|
|
* `process.env.GSTACK_HOME = ...` leaks into every sibling file in the
|
|
* shard. The damage was real before the 2026-08 sweep: relink.test.ts:28
|
|
* documents a "fresh install" test seeing a neighbor's skill_prefix, and
|
|
* cdp-e2e once baked a sibling's temp dir into artifacts that outlived it
|
|
* (dangling symlinks into a deleted render dir).
|
|
*
|
|
* The pattern is: save the original, assign in beforeAll, restore in
|
|
* afterAll — confining the value to the file's execution window.
|
|
*
|
|
* Heuristic: repo test files write module-scope statements unindented, so a
|
|
* column-0 assignment is module scope; indented assignments (inside hooks,
|
|
* tests, or helpers) are fine.
