Motivation

Every directory listing skips an entry named dist, a workaround so that a tool listing the folder holding its own dist doesn't miss on a clean checkout. It helps no other folder name and hides a dist that does matter. A dist folder appearing in a folder the task listed goes unseen, and the next run replays stale output: oxlint, for example, passes from the cache after a dist folder with lint errors appears.

Changes

Listings skip only ., .. and .DS_Store. A task's own dist doesn't need the skip anymore, since #915 makes a rebuildable folder an ignored entry. No other snapshot changes.

E2E cases: dist_appears_in_listed_folder (synthetic, vtt list-dir) and oxlint_dist (oxlint -D no-debugger). Both are false hits today and correct misses after.

Part of a stack that lets automatic tracking cache tasks which read their own outputs and list the folders holding them, so they also hit on a clean checkout.

Note

Medium Risk
Touches cache input fingerprinting for all tasks that list directories; behavior change is intentional but could shift hit/miss rates for workflows that relied on ignoring unrelated dist folders.

Overview
Directory listings used to drop every entry named dist, so a dist folder that appeared or vanished in a listed directory never changed the cache fingerprint and the next run could replay stale cached output (e.g. oxlint still passing after dist/bad.js showed up).

should_ignore_entry in post-run fingerprinting now skips only ., .., and .DS_Store. A dist the task itself wrote is still excluded from listings via the existing rebuildable-entry logic from #915, not a hard-coded name.

E2E snapshots dist_appears_in_listed_folder and oxlint_dist lock in a cache miss when an external dist appears.
