…one violation AGENTS.md states the rule plainly: "Frontend config centralized in app/src/utils/config.ts -- never read import.meta.env directly elsewhere." Nothing enforced it, and it had already drifted: TwoPanelLayout's debug() read import.meta.env.DEV directly. The rule is not cosmetic. config.ts owns derived values a raw read cannot give you -- IS_DEV_LIKE exists precisely because import.meta.env.DEV is false under the E2E harness (vite build --mode development sets PROD=true), which the comment beside it spells out. A raw read is also unstubbable once the module graph has loaded; loopbackOauthListener.test.ts already documents that, and reads through config for exactly this reason. Adds a no-restricted-syntax rule over src/**, exempting config.ts itself and test files, with a message naming the replacement. Scoped narrowly: vite.config.ts must define these values and is outside src/. The one violation is fixed by importing IS_DEV. That is deliberately behaviour-preserving -- IS_DEV is exactly import.meta.env.DEV. If the intent was for this debug output to appear under the E2E harness too, IS_DEV_LIKE is the one-word change, but that is a behaviour decision rather than a lint fix, so I left it alone. Verified: with the rule added and the source untouched, eslint reports exactly one error, at TwoPanelLayout.tsx:17. After the fix the run returns to the baseline 98 warnings / 0 errors -- no new warning anywhere. prettier --check clean on both files, tsc --noEmit clean, and TwoPanelLayout.test.tsx 7/7.

- Around line 160-165: Update the no-restricted-syntax selector in the ESLint
configuration to match only import.meta.env, excluding new.target.env; add a
corresponding selector for computed access import.meta['env'], and add tests
covering both property forms.

Follow-up: the full unit suite finished, so here is the complete number rather than just the targeted file.
The single failure is Verified rather than assumed — checked out the base commit Identical. My first attempt at this control was invalid — I ran So the suite result for this PR is 9302 passed with no regression, and the one red file is red on |
CodeRabbit found two real holes in the selector, both reproduced with
eslint before changing anything:
import.meta.env.DEV flagged correct
import.meta['env'].DEV NOT flagged a silent bypass of the rule
new.target.env flagged false positive; a different
meta-property entirely
Computed member access stores the key on property.value, not
property.name, so the original selector never saw the bracket form. And
[object.type="MetaProperty"] matches new.target just as well as
import.meta, so the meta-property is now pinned by name.
Adds a test that reads the selector and the ignore list out of the real
eslint.config.js rather than restating them, so the two cannot drift.
Reverting the selector turns exactly the two cases above red and nothing
else. The probes run through a bare Linter because the repo config is
type-aware and parserOptions.project rejects a synthetic file path.
tsc, eslint, prettier and the new tests are all clean.

CI's format:check flagged it. My local check had reported clean because I read prettier's filtered output instead of its exit code -- the file was failing the whole time.

config.tsowns derived values a raw read cannot give you. Its own comment says so:A raw read is also unstubbable once the module graph has loaded —

I swept all of
