From b783410815efad3a4a00760f6950596da49f2af6 Mon Sep 17 00:00:00 2001 From: Tom Boucher Date: Sun, 14 Jun 2026 20:52:56 -0400 Subject: [PATCH] refactor(#1191): inject clock/reset testability seams + handle valid-null settings (#1233) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * refactor(#1191): inject clock/reset testability seams + handle valid-null settings - worktree-safety reapOrphanWorktrees: injectable deps.nowMs clock for deterministic stale-lock boundary tests (mirrors snapshotWorktreeInventory's options.nowMs). - active-workstream-store: _resetControllingTtyCacheForTests() seam clears the memoized controlling-TTY probe cache; test replaces require.cache busting. - gen-capability-registry: export stripGeneratedComment (additive); test imports the real helper + equivalence assertion, keeping the deliberate drift oracle. - install.js readSettings: a successfully-parsed JSON null is treated as empty settings ({}) instead of being mis-reported as malformed; genuine parse failures still warn. readSettings/stripJsonComments exported (GSD_TEST_MODE-guarded require) for real behavioral tests. Closes #1191 Co-Authored-By: Claude Opus 4.8 * chore(#1191): add changeset for valid-null settings fix (#1233) Co-Authored-By: Claude Opus 4.8 * fix(#1191): replace Stryker-incompatible structural reset test with behavioral isTTY-spy The seam-2 reset test read the BUILT active-workstream-store.cjs and grepped for 'didProbeControllingTtyToken = false' — Stryker instruments that file so the literal is absent, failing the mutation DRY RUN. Replaced with a behavioral test that spies on process.stdin.isTTY access count to prove a post-reset probe re-runs (kills the didProbe-reset mutant) without reading source text. Local stryker: dry run passes, score 85.21% >= 80.
