 # Changelog
 
+## [1.94.23.0] - 2026-11-03
+
+**Two `gstack-pregate` preflight false positives fixed (GST-1211).** Both stopped /ship on real work in gbrain-evals.
+
+### Fixed
+- **`strays`:** the scratch-name check matched three prefixes the docs never listed (`temp`, `debug-` and `probe`), so real files like `probe.py` and `temporal-graph-shipped.test.ts` failed preflight. It now matches only the documented names: `zz-*`, `tmp*`, `scratch*`, plus editor leftovers (`*.orig`, `*.rej`, `*.swp`, `*.swo`, `*.bak`, `*.tmp`, `*~`, `.DS_Store`, `Thumbs.db`), which docs/pregate.md and docs/troubleshooting.md now list too.
+- **`literals`:** a named literal the branch only adds, such as `limit: 300` in a new object, was read as an existing `limit: 10` elsewhere in the file changing to 300, and every test that mentioned 10 was flagged. The check now compares every value under a name, so an added literal isn't a change. Editing an existing value still fails, and so do two cases the old last-value check could miss: changing one of two equal values under the same name, and deleting one site while editing another.
+
+### Tests
+- `test/pregate-selection.test.ts`: `probe.py` and `temporal-*.test.ts` pass `strays` while `zz-notes.md`, `tmp-x.ts`, `scratch.py` and `util.js.orig` still fail; a new object literal beside `limit: 10` passes `literals` while editing that value still fails; the pure `changedLiterals` case keeps an exported constant change.
+
 ## [1.94.22.0] - 2026-11-03
 
 **/investigate, /review, /qa and /verify now say when to use them, and /investigate and /review declare what "done" means (GST-1088 lane B).** Untold, Opus 5.5 never opened /investigate in 252 trials (Run D, gstack-evals#140). A when-to-use description raised GPT-6.1 Sol's open rate from 9.5% to 27.0% in the same run. Claude Code's catalog shows only a description's first sentence, so each of the four now opens with a "Use when ..." sentence. The routing hook and the contract check that read the new frontmatter landed in v1.94.6.0 (lane A, off by default; see docs/skill-routing-and-contracts.md), so the "Done means" list now also names `gstack-skill-contract check` and `waive`.
