From f3515a0442573aad9f3cd81b89da70e056aafc5f Mon Sep 17 00:00:00 2001 From: WebPerson Date: Thu, 1 Oct 2026 09:44:30 -0500 Subject: [PATCH 1/2] fix(ci): prune 6 stale eslint suppressions that made `npm run lint` exit 2 (#15159 G-05) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ESLint fails an entire run when the suppressions file carries entries whose violation no longer occurs: There are suppressions left that do not occur anymore. To resolve this, re-run the command with `--prune-suppressions` … So the debt is not cosmetic — `npm run lint` exited **2** on every PR. The step in ci.yml is the `lint` job, which gates every other job through its own failure. Six entries were stale. All six are `@typescript-eslint/no-unused-vars`: open-sse/translator/request/openai-to-cursor.ts (3) src/app/(dashboard)/.../settings/components/SystemStorageTab.tsx (1) src/app/api/v1/vscode/[token]/combos/route.ts (1) src/app/api/v1/vscode/raw/[token]/combos/route.ts (1) src/lib/oauth/providers/ghe-copilot.ts (1) tests/unit/cursor-agent-session.test.ts (?) Each was re-linted directly with an EMPTY suppressions file and `no-unused-vars` forced to error: zero violations on all six. That check is also why pruning is safe to do on one platform and land on another — `no-unused-vars` is platform-independent, so the Windows dev machine and the Linux CI runner produce the same file. 1094 → 1088 suppressed violations; nothing else changed. ## Verification (release/v3.8.52 @ dbe703a000) | Check | Before | After | | --- | --- | --- | | `npm run lint` | **exit 2** | **exit 0** | | `lint:json` totals (11786 files) | — | 0 errors, 0 warnings | | suppressed violations | 1094 | 1088 | | diff | — | exactly 6 removals, 1 insertion (trailing comma) | The ratchet metric does not move: the baseline note already records that `lint:json` measures 0 with suppressions applied, and a pruned entry was not counted before or after. ## Tests `tests/unit/build/eslint-suppressions-pruned.test.ts` — 6/6. Five are cheap and pin the invariant: the six known-stale entries stay gone, no empty file/rule buckets survive a hand-edit, suppression keys stay POSIX-relative (a backslash key silently stops matching, which looks identical to "unpruned" from the gate's exit code), and a `SHAPE-SANITY` case pins that the file is keyed by FILE first, then rule. That last one exists because the first draft of this suite got the nesting backwards — every lookup missed, and "no stale entries" passed **vacuously** while the gate was red. A test that cannot fail proves nothing; the sanity case is what makes the other four trustworthy. The sixth runs the real ESLint gate on the real repo (~3.5 min) and asserts it does not exit 2.
