fix(gitlab): scope MR automation switches per linked MR - #2676
Conversation
📝 WalkthroughSummary by CodeRabbit
WalkthroughGitLab MR automation switches now apply independently to each linked merge request. The backend stores and evaluates per-MR options, APIs accept MR identity selectors, and the web UI renders isolated controls for each MR. Legacy task-level values migrate to per-MR rows. ChangesPer-MR GitLab automation
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to The PR correctly scopes automation switches per merge request, but current behavior can still leave task and MR settings inconsistent after a failed update, reuse stale lifecycle state, target the wrong MR from malformed input, or execute unintended commands in the seed script. These are bounded but concrete merge-readiness risks that should be fixed or explicitly accepted before merging. Suggested reviewers: Poem

The severity depends on how often username and switches are patched together. If it is rare, document the partial-apply behaviour. If it needs to be atomic, both writes belong in a single outer transaction. Also, the comment on the second call says "One transaction for every target" — it should say "One transaction covering all targets".

![github-actions[bot]](https://avatars.githubusercontent.com/in/15368?s=60&v=4){kind=small}
The five automation switches (auto_fix_enabled, auto_merge_enabled, prompt_on_review_requested, prompt_on_merged, prompt_on_closed) were stored task-level in gitlab_task_mr_options, so toggling one linked MR's control changed every MR on the same task. Adds a new per-MR gitlab_task_mr_automation_options table keyed by (task_id, repository_id, project_path, mr_iid), a marker-guarded one-time fan-out migration from the legacy task-level row, and threads the per-MR values through the store, service, HTTP controller, orchestrator consumers, and MCP handlers. The auto-fix prompt override and resolved reviewer username remain task-level. Also forwards MR identity (repository_id/project_path/mr_iid) and the auto_fix_enabled/auto_merge_enabled/auto_fix_prompt_override fields through the update_task_mr_automation_kandev MCP tool wrapper, which previously silently dropped them before they reached the WS handler.
MRAutomationControls now requires a concrete mr prop instead of an optional single ?? undefined, since all five switches are per-MR. The multi-MR topbar dropdown renders one collapsible Automation block per linked MR, each labelled with its MR number (mrAutomationAppliesToMR), auto-expanding Review follow-up only when that MR's own switches are on. Element ids and aria-describedby targets are suffixed with the MR association id so simultaneously mounted per-MR blocks in the dropdown don't collide. use-task-mr-automation's optimistic update merges a patch into the targeted MR's entry in mr_options instead of the task-level aggregate. Adds a two-linked-MR independence spec to both the desktop dropdown and mobile touch-dropdown Playwright suites, extracting seedGitLabMRData from seedGitLabReview so seeding a second MR on the same workspace doesn't invalidate the first MR's mock data (configureGitLab rebuilds the cached workspace client on every call).
Updates the GitLab integration spec's Automation section and data model, the lifecycle-notifications ADR (amended note on the switches' scope moving from task to per-MR), and the two public docs pages describing the MR topbar Automation controls.
Review follow-ups on the per-MR automation switches. Unlinking an MR left its gitlab_task_mr_automation_options row behind, so re-linking the same MR — by hand or through push-detection auto-link — silently re-armed whatever was configured before, including auto-merge. No surface showed it (taskMRAutomationOptionsList hides rows whose MR is not linked) but the evaluator still read it. DeleteTaskMRForWorkspace now drops the row in the same transaction. The fan-out that applies a switch patch to every linked MR ran one transaction per MR, so a failure partway through returned an error to the caller with the switch already armed on the MRs committed before it. UpdateTaskMRAutomationOptionsForMRs applies the whole batch in a single transaction instead; the single-MR entry point delegates to it. A switch update on a task with no linked MRs returned 200 and stored nothing, because the switches only exist per MR. It now fails with the ErrTaskMRNotLinked sentinel, so HTTP answers 400 and MCP a validation error. The task-level auto-fix prompt override stays settable. The one-off manual seed script hardcoded an absolute path from the environment it was written in; it now resolves from __dirname, and its scratch directory is gitignored. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
… layers The orchestrator mock's GetTaskMRAutomationEvaluation ignored the MR identity arguments and returned one shared options value, so no orchestrator test could express "enabled on MR A, off on MR B" — the one case the task called for. It now honours an optional per-IID map; left nil it behaves exactly as before, so existing tests are unchanged. TestHandleTaskMRLifecycleAutomation_AutoMergeOnOneMRDoesNotMergeAnother enters through handleTaskMRLifecycleAutomation rather than calling handleTaskMRCIAutomation with hand-built options, since the per-MR resolution under test happens in GetTaskMRAutomationEvaluation. Verified non-vacuous: enabling auto-merge on the sibling MR makes it fail with "MergeMRForAutomation calls for MR !2 = 1, want 0". TestControllerPatchTaskMRAutomation_RejectsSwitchesWithNoLinkedMRs adds the HTTP half of the zero-target rule, which was only covered at the service layer: a switch patch on a task with no linked MRs answers 400, while the task-level auto-fix prompt override still answers 200. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Store.DeleteTaskMR cascaded to gitlab_task_mr_state but not to the new gitlab_task_mr_automation_options table, unlike DeleteTaskMRForWorkspace. A caller routed through it would leave an enabled switch — including auto-merge — for the next link of the same MR to inherit silently. Also correct the spec's dropdown description: only the nested Review follow-up group is collapsible, not the whole per-MR Automation block. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The chip's auto-fix and auto-merge badges read the response's task-level
booleans, which this branch redefined as an aggregate ("every linked MR
has this on"). With auto-fix enabled on one of two linked MRs the
aggregate is false, so selectBadgeMR returned null and the chip showed
no auto-fix badge and no N/10 round counter while auto-fix was actively
spending its round budget. Auto-merge under-reported the same way.
Read each MR's own mr_options row instead, light a badge when any open
MR has that switch on, and pick the round from the MRs whose own
auto-fix is enabled. Mirrors the merged GitHub side (kdlbs#2512,
automationForPR / automationForPRs in pr-status-automation-badges.tsx);
falls back to the task-level booleans only when mr_options is absent.
Fixtures that paired open MRs with an empty mr_options modelled a state
the backend cannot emit, so they asserted nothing about the per-MR path;
they now carry a matching row.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The existing badge spec links a single MR, where the response's aggregate booleans and that MR's own switches are always equal — so it passed both before and after the per-MR badge fix and proved nothing about it. Add a two-MR case that arms automation on one MR only, pins the aggregate as false first so a pass cannot come from the old code path, and asserts the chip still renders both badges with the armed MR's round. Mutation-verified: reverting mr-status-chip-selection.ts to the aggregate reads fails this spec at the auto-fix badge visibility assertion. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…ances A task with N linked MRs now mounts N MRAutomationControls, each with its own useTaskMRAutomationOptions(taskId) instance reading and writing the same task's store slot. Each instance previously kept private useRef counters for request ordering, so an older instance never learned about a newer instance's save and could commit its own stale response over a fresher one from a sibling instance. Moves refreshRequestRef/updateRequestRef/updateSettleCounterRef into a WeakMap keyed by the store API, shared by every hook instance reading the same store, so ordering guards see saves and refreshes from all mounted instances of a task, not just their own. Regression test mutation-verified: fails with the previous per-instance useRef behavior, passes with the WeakMap fix.
check-new-e2e-sleeps.mjs flags any new e2e/ file's unconditional setTimeout-based sleep; manual-seed-gitlab-mr-automation.ts's poll loop for the initial agent-setup profile needs the sanctioned dwell(ms, category, reason) helper instead, categorized as poll-interval.

GitLab MR automation switches (auto-fix, auto-merge, and the three review-lifecycle notifications) were stored per task, so enabling one switch on a linked merge request silently enabled it for every other MR linked to the same task, including auto-merge, which can land code unintentionally. Mirrors the equivalent GitHub PR automation fix (#2512) by moving all five switches to a per-MR table, keeping only the auto-fix prompt override and resolved reviewer identity task-level.

Possible Improvements
Low risk: automation behavior is now stricter (per-MR keyed polling/gating) rather than looser, the migration is idempotent and marker-guarded, and the request-ordering race is closed with a mutation-verified regression test — but see the two open questions below on behavior changes worth a reviewer's explicit sign-off before merge.
Review notes carried from QA (please confirm the two open questions below)
Fixes already applied during QA, listed for visibility (see Important Changes above for detail):
c214902e9, regression spec in136351f22). Mutation-verified: reverting the fix fails the new spec at the badge-visibility assertion.MRAutomationControlsinstances (6883d8a55). Mutation-verified: the regression test fails against the prior per-instanceuseRefbehavior and passes with theWeakMapfix.Open questions for the author/reviewer:
PATCHcarrying any of the five switches at a task with zero linked MRs now returns 400 (the task has no linked merge requests). Previously the value persisted on the task row and a later-linked MR inherited it. The prompt override still returns 200 there, and no UI path can hit it (the controls only render per linked MR), but it is a real behavior change for an MCP agent that used to pre-arm switches before opening an MR.workspace_idis not an authorization input on this route — confirm?GET/PATCH .../tasks/{taskID}/mr-automationsucceed with a wrong, bogus, or omittedworkspace_id; scoping comes fromauthorizeTaskMRAccess(taskID)and is intentionally unscoped with auth disabled. A nonexistent task correctly 404s. This is pre-existing route behavior this branch does not change, but it is asymmetric withDELETE /task-mrs/{id}, which does useworkspace_id.Pre-existing issues found during QA, out of scope here, tracked separately:
