+- A pregate guard whose exact command already passed at this tree no longer runs again (GST-1186). When the base branch's `ship_lanes_from` maps the command, it is carried from the verified CI run through the same `gstack-evidence record-ci` path /ship lanes use (`GUARD: <id> carried runs=…`); otherwise a counted local ledger pass of that command at the same working tree stands (CI rows count only through a live `record-ci` check) (`GUARD: <id> reused …`, and the new read-only `gstack-evidence passed -- <command>`). Repos whose suites are guards, like founderstar, stop rerunning about six minutes of suites per /ship. See docs/pregate.md#guard-carry.
 - Known limit: `ship_lanes_from` is still read from `origin/<base>` only, so the PR that adds a mapping cannot carry from it.
 - A `ship_lanes_from` entry can name the CI jobs that run a lane instead of an inventory command: `{ "profiles": [...], "jobs": ["verify", "typecheck"] }`, exactly one of the two (GST-1189). It carries only when every named job succeeded in the newest attempt of the verified run at HEAD's tree, through the same `verifyRun` job check. A missing job refuses as `job_missing` and a skipped one as the new `job_skipped`. Lanes with no test files, like gbrain's verify and typecheck (run 41564913688) or harness-evals' `bunx tsc --noEmit`, can now carry, and they record `tests_ran=n/a`. Fake `check:<command>` entries in `tree.json` can move to this form. A repo declaring `jobs` should raise its `min_gstack_version` to this release first, since older gstack rejects the key. See docs/pregate.md#ship-lanes-jobs.
 
 - A `ship_lanes_from` entry can declare `aliases`, other exact spellings of the same lane such as `env -u ANTHROPIC_API_KEY bun test tests/` (GST-1190). gstack never strips env prefixes on its own, since an `env -i` run is a different environment.
 - A carried lane no longer reports the whole run's test count. An inventory lane reports how many of its files the run covered, labeled as a file count (alphaclaw's 46-test guards lane recorded 9677 before).
-- `gstack-ship-preflight --tests-only --policy-from head --simulate` proves a new mapping before it lands: every line starts `SIMULATION:`, nothing runs, no evidence row is written and nothing clears.

+- `gstack-ship-preflight --tests-only --policy-from head --simulate` proves a new mapping before it lands: every line starts `SIMULATION:`, no lane runs, no evidence row is written and nothing clears. An inventory-mapped lane runs the branch's inventory command, so the dry run needs `--allow-repo-commands`. A branch's own map never carries, so the first pull request that adopts a mapping pays its full lanes.
 - `gstack-evidence carried`, which the ship receipt reads, lists only rows the receipt base's policy mapped, so a run against another base never lands in a receipt.
 - An unknown `.gstack/pregate.json` key under a `min_gstack_version` above the running gstack now says `needs gstack >= <version>; upgrade` (`PREGATE_GSTACK_TOO_OLD`). It still refuses.
 - docs/pregate.md#prove-a-mapping documents the proof route, the version floors, and that `tree.json` writers using Bun's JUnit must take the root `testsuite` count.

A /ship lane or guard whose inventory names one carries the covered files and runs only the skipped ones here, through the `per_file` runner its `ship_lanes_from` entry declares (for gstack, `bun test --timeout=30000 {files}`, so gstack runs just its 6 runner-skipped files). The CI row is written only after that run passes (`skipped_failed` otherwise), and an entry without `per_file` refuses as `inventory_skipped`, naming the files. A partly skipped file still counts.

@@ -20,3 +20,5 @@
 - `test/ship-ci-carry.test.ts` (GST-1190): an alias carries and an undeclared env prefix does not; a narrow lane reports its covered file count, not 9677; a jobs-mapped `bunx tsc --noEmit` guard carries with `n/a`; the newer-gstack message; `--simulate` writes and clears nothing and the branch's own map never carries; `carried` drops a row another base mapped. Six of these fail without the change.
 - `test/ci-tree-reuse.test.ts` and `test/ship-ci-carry.test.ts` (GST-1190 skipped files): the writer lists only fully skipped files and leaves the list out without complete counts; a fully skipped inventory file stops the lane carry, an empty list or older `tree.json` carries, and the tests stage runs only the skipped selected file. All three fail without the change.
 - `test/ship-ci-carry.test.ts` (path-skipped jobs and `find --simulate`): a skip under an unchanged, green gate is not owed; a changed workflow, a changed gate script or a failed gate job runs the lane here; `find --policy-from head --simulate` prints only SIMULATION lines and writes nothing. All five fail without the change.
+- `test/ship-ci-carry.test.ts` (review fixes): a gate script behind `${{ github.workspace }}`, under `working-directory` or behind a package script is compared; the gate is the job, not a same-named step; only a `pull_request` run's skip counts; a skippable profile must declare `scripts`; `passed` never counts a CI row; a path-skipped guard says not owed; `--simulate` runs a branch inventory only with `--allow-repo-commands`. Eight fail without the fixes; a newer-failure veto test covers existing behavior.
+- `test/ship-ci-carry.test.ts` (per-file lane carry): the covered file carries and only the skipped file runs through `per_file`, a failing remainder records no CI row and runs the lane whole, and `per_file` needs `{files}` and an inventory entry. All three fail without the change.
