+**A pull request can clear its remote gate obligation from a run with named flaky failures, once the owner grants it (GST-1096).** A timing flake in a test file the pull request never touched used to keep the pregate red with no way through but another paid run. `gstack-pregate clear --remote <lane> --run <id|url> --flaky-exception "<file>::<case>" --pr <n> --grant <approval id>` now accepts such a run when every failure is named from the run's own shard results and logs, at most three cases, each file outside the pull request's diff and its import closure, none paid and none a security scan test, and a gstack-approvals row in the owner's words binds the repository, PR, head, tree, lane, run attempt and cases. It is pregate only: a red required CI check still needs its own green run.
+
+### Added
+- **`--flaky-exception`, `--pr` and `--grant` on `gstack-pregate clear`** (`lib/pregate/flaky-exception.ts`). Every job of the run attempt is reconciled (only test-shard jobs and their aggregate may fail), every planned shard needs a complete result, and each failed shard's log must name no failure its result leaves out. Without `--grant` the clear checks everything and prints the exact `gstack-approvals add` command, whose scope is a digest of everything the grant binds, so a grant can never be moved to another head or case list.
+- **`pass-with-exception`.** pregate.json records `exceptions`; `gstack-pregate verify` re-checks the binding offline and prints `PREGATE: pass-with-exception (<cases>; grant <id>)`; `gstack-ship-queue ready` accepts it and prints a `FLAKY_EXCEPTION:` line; the ship receipt records `flaky_exception`.
+- **docs/pregate.md#flaky-exception**, including why `base_red` is not used: it proves a failure by reproducing it on the base, and a timing flake passes there.
+
+### Tests
+- `test/pregate-flaky-exception.test.ts`: a red run with one named flake clears once the bound grant exists, and verify, ready and the receipt report it; refusals for an unnamed or extra failure, a case that did not fail, more than three cases, an unattributed failure, a failed non-shard job, a missing result or log, a timed-out shard, a log failure the result omits, a file in the diff or its import closure, a paid or security test, another head, another PR head, a newer run, a moved attempt, and a grant with another scope, outcome or speaker; ready still refuses red CI. These tests failed before the change.

+## Owner-granted flaky exception
+
+A timing flake in a test file the pull request never touched can keep a remote
+gate obligation red: the rerun hits the same 5 s timeout on a loaded runner,
+and nothing in the diff can fix it. `clear --flaky-exception` lets the owner
+accept named cases for one head, on the run's own records:
+
+```bash
+gstack-pregate clear --remote pregate.json/remote_gate --run <id|url> \
+  --flaky-exception "test/docsync-fault-interface-legacy.test.ts::rejects legacy-third" \
+  --pr <n> --allow-repo-commands
+```
+
+The first call checks everything below and then refuses with
+`reason=grant_needed`, printing the exact `gstack-approvals add` command to run
+once the owner says yes: its `--scope` is `flaky-exception:<sha256>`, a digest of
+the repository, PR, head, tree, lane, every run with its attempt, and the sorted
+cases. Record the owner's exact words in that row, then rerun the same clear with
+`--grant <the row id>`. The obligation clears only when all of this holds:
+
+- **Every failure is named from the run's own records.** A red run uploads no
+  `tree.json`, so the clear reads the strict shard runner's artifacts instead
+  (`free-plan`, `free-result-<n>` and `free-test-shard-logs-<n>` in
+  `free-tests.yml`; the `windows-` names in `windows-free-tests.yml`; any other
+  workflow refuses with `no_shard_results`). Every job of the attempt is
+  reconciled: only the shard jobs (`free-suite (<n>)`) and the aggregate that
+  needs them may fail, every job the profile requires must pass, and any other
+  failed or cancelled job refuses (`unnamed_failure`). Every planned shard needs
+  its result; a missing result, a timed-out shard or a missing summary is
+  `shard_incomplete`. A failure the runner could not attribute to a test file,
+  an unhandled error between tests, or a `(fail)` line in a failed shard's log
+  that its result does not record refuses. A retry that passed is a recovered
+  flake; a retry that failed again keeps its own failures.
+- **The cases are exactly the failures.** At most three, written as
+  `<test file>::<test name>` the way the run printed them. A failure no
+  `--flaky-exception` names refuses (`unnamed_failure`), and so does a named
+  case that did not fail (`case_not_failed`). The refusal lists the run's
+  failures in that form.
+- **The files are not the PR's business.** A named file in the PR's diff
+  (`case_in_diff`), or one the import graph reaches from any changed path
+  (`case_in_closure`, lib/pregate/import-graph.ts with the base branch's
+  `dependencies`), refuses. A paid test file (`case_paid`) and a test of a
+  security scanner (`case_security`: cso, secrets, gitleaks, sealed, redact, osv)
+  are never excepted. Security scans themselves are pregate checks and CI jobs,
+  not test cases, so no exception can reach them.
+- **One head, one grant.** The runs must have tested pregate.json's own head and
+  tree, with no stamp-only substitution (`head_mismatch`); the PR must be open with
+  that head (`pr_mismatch`); no newer run of the workflow may exist on the head
+  (`newer_run`), and the run may not move to another attempt during the check
+  (`run_changed`). The grant row must carry this exception's scope
+  (`grant_mismatch` otherwise), record `approved` (`grant_not_approved`) and be
+  the owner's words, not an agent's (`grant_not_owner`). A new head needs a new
+  run and a new grant; a grant is never rebound.
+
+pregate.json records the grant under `exceptions` (lane, repository, PR, head,
+tree, runs, cases, grant id, who said it, their words and the binding), and the
+obligation's receipt adds `exception=<grant> cases=<n>` to the usual run fields.
+The verdict becomes `pass-with-exception`. `verify` re-checks offline that each
+exception receipt has its entry, bound to this head and tree, with a binding that
+still matches its fields, and prints
+`PREGATE: pass-with-exception (<cases>; grant <id>)`. `gstack-ship-queue ready`
+accepts it and prints one `FLAKY_EXCEPTION:` line per exception in the READY
+block, and `gstack-ship-receipt write` records `flaky_exception` (lane, runs,
+cases, grant, who).
+
+**Pregate only.** The exception clears the pregate obligation and nothing else.
+It never waives a red required CI check: `ready` still needs every required check
+green at the exact head, so a red Free Tests check on the pull request needs its
+own rerun to pass. Changing that contract is a separate decision for the owner.
+
+**Why not `base_red`.** `base_red` (docs/ship-policy.md#base-red) proves a
+failure belongs to the base by reproducing it there, at the base head and at the
+PR head. A timing flake usually passes on the base (the 2026-11-02 docsync case
+passed in 3.5 s on main and failed at 5 s on the PR's tree), so `base_red`
+returns `IN_BRANCH` and refuses. The exception path asks a different question:
+not "is the base broken?" but "is every failure named, outside this PR, and
+accepted by the owner?"

+/**
+ * pregate flaky exception (GST-1096, docs/pregate.md#flaky-exception): an owner-granted exception that lets GitHub
+ * Actions runs with failures clear one requires-remote obligation. `gstack-pregate clear --remote <lane> --run <run>
+ * --flaky-exception "<test file>::<case>" … --pr <n> --grant <approval id>` (lib/pregate/index.ts clearByRuns) takes
+ * the runs only when:
+ *
+ * - every failure is named from the run's own records: each job of the attempt reconciles (only test-shard jobs, and
+ *   the aggregate that needs them, may fail), the plan and every shard's strict result are present and complete (a
+ *   timed-out or unattributed shard is incomplete evidence), and each failed shard's log names no failure its result
+ *   omits;
+ * - the named cases are exactly the failures, at most three, none in a paid test file or a test of a security scan,
+ *   and each file is outside the PR's diff and the diff's import closure (lib/pregate/import-graph.ts);
+ * - the runs tested pregate.json's own head and tree (no stamp-only substitution), the PR's head is that head, and an
+ *   approved gstack-approvals row in the owner's words carries the scope `exceptionBinding` computes over repository,
+ *   PR, head, tree, lane, runs with their attempts and cases, so it cannot be rebound to another head or case list.
+ *
+ * It is pregate only: nothing here touches a required CI check, which still needs its own green run at the head.
+ * base_red is not used: it proves a failure by reproducing it on the base, and a timing flake passes there.
