Fix Vale 3.15+ dicpath resolution — drop stray StylesPath from package .vale.ini

[rrrutledge]

Summary

Every repo that consumes this package's ISC.zip (InnerSourcePatterns, InnerSourceLearningPath, managing-innersource-projects) has been hitting vale: unable to resolve dicpath on every file since Vale 3.15.0 (released 2026-06-12) — unrelated to any PR's content. InnerSourcePatterns and InnerSourceLearningPath are actively broken today; managing-innersource-projects pulls the same unpinned releases/latest package and will hit it on its next vale run.

Root cause

ISC/.vale.ini's StylesPath = styles line was written for developing this package standalone and was harmless once distributed — older Vale never read a package's own .vale.ini as live config for consumers.

Vale 3.15.0 changed vale sync to create/honor the configured StylesPath (vale-cli/vale#1106). As a side effect, it now also installs this inner .vale.ini as a real sub-config for consumers (.vale-config/0-ISC.ini). Sync flattens this package's files into the consumer's StylesPath, so StylesPath = styles no longer points anywhere real — and it shadows the consumer's actual StylesPath when the Spelling check resolves dicpath: dictionaries, failing on every file in every consuming repo.

Fix

Drop the stray StylesPath line. Verified locally: reproduced the failure with Vale 3.15.1 against InnerSourcePatterns, removed this line from the synced sub-config, and vale went from the dicpath crash straight to real spell-check output (flagging real typos like "Ingka", "Moulis", "Contribfest").

Note on rollout

The Release workflow fires automatically on push to main under ISC/**, so merging this PR publishes a new release immediately — every consumer on releases/latest (all three above) picks it up on their next vale sync. InnerSourcePatterns currently has a stopgap version-pin (#916 there) that this fix supersedes; closing that once this is out.

[rrrutledge]

Heads up: the vale check on this PR will stay red — it fails on unable to resolve dicpath, but that's this repo's own self-check (README.md) hitting the currently published (still-broken) releases/latest package, since the fix only ships once this merges. Chicken-and-egg: merging is what publishes the release this check needs to pass. (fail_on_error: false is set, but vale erroring outright — vs. just reporting lint issues — still surfaces as a failed status via reviewdog.) Safe to merge past it.

Amazing @rrrutledge. I tried to fix this for a bit but was not able to find the issue.

I did not test this myself now but your reasoning sounds so convincing that I just merge this.

Fingers crossed that vale works again now :)

I re-ran a vale check on the InnerSourcePatterns repo that previously failed. Now it works!

Also re-ran the check on this PR here, also works:

I did not check if spelling issues are correctly annotated now, but at least the action does not fail anymore :) So I am just assuming that it is all working now.
