bug(plugin-view): a stray groupBy in viewOptions.kanban overrides the lane generateViewSchema just resolved — the second route, untouched by objectui#8365 #9242
Description
Found by the os-dev seat while landing objectui#8365 (PR #9236). ⛔ Not claimed, not repaired there: it is a different package and a different renderer, i.e. validation surface outside that card's fence.
The defect — the same shape objectui#8365 just closed, one renderer over
plugin-view's generateViewSchema kanban branch resolves the lane and then spreads the rest of the config after its own groupBy:
const kanbanCfg = viewOptions.kanban || {};
const groupBy = kanbanCfg.groupByField || kanbanCfg.groupField || 'status';
const { columns: _c, groupByField: _gbf, groupField: _gf, titleField: _tf, conditionalFormatting: _cf, ...restKanban } = kanbanCfg;
return { type: 'object-kanban', ...baseProps, groupBy, titleField: ..., cardFields, ...restKanban, ... };
groupBy is not in that destructure, so a viewOptions.kanban.groupBy survives into restKanban and the trailing spread overrides the lane the branch just resolved from groupByField. That is exactly the defect objectui#8365 measured and closed in ListView.
Why it is a SECOND route, not a duplicate
generateViewSchema runs precisely when no host supplied renderListView — the authored object-view element — so it never passes through ListView and PR #9236's destructure fix does not reach it. The same distinction plugin-view's own calendar branch records for objectui#7029.
What PR #9236 already does cover
The CONTRACT half is global: @object-ui/types' view-level KanbanConfig mirror now declares groupBy as a named alias refusal pointing at groupByField, and the legacy options.kanban nesting takes the same message through a check. So a view carrying the key is refused at every validating door for BOTH routes. What remains here is a BEHAVIOUR gap, not a contract gap: a document that never went through a validator still re-points this renderer's lane.
Suggested repair
Add groupBy to the destructure, exactly as PR #9236 did for ListView, and pin it with the same distinguishing fixture (two DIFFERENT lane names, so the arm can fail):
viewOptions.kanban = { groupBy: 'LANE_FROM_STRAY_GROUPBY', groupByField: 'LANE_FROM_CANONICAL' }
=> the generated object-kanban node must carry LANE_FROM_CANONICAL
ListView twin worth measuring before writing the pin: this branch floors the lane at the literal 'status' when neither declared key is present, where ListView falls back to detectStatusField(objectDef). So the "stray key alone" control behaves differently here and should be measured rather than copied.
Dedup — declared rather than implied
One search_issues call over open AND closed issues in this repo, phrased as a sentence describing the defect: 22 results, top 10 read. The control fired — objectui#8365 itself came back first, so the reading is a reading. Nearest neighbours, neither of them this: objectui#7773 (both adapters writing the retired groupField ALONGSIDE groupBy onto the generated node — node-local, closed) and objectui#8213 (the producer that fed the ListView override, closed). No card names this branch's spread order.
Filed by the os-dev seat that delivered objectui#8365, session session_01UzHd6hDYatoDn17BuwKxnZ, recorded here as prose because an attribution footer does not survive issue creation.

Added groupBy: _strayGroupBy to the :1364 destructure of viewOptions.kanban in packages/plugin-view/src/ObjectView.tsx, same shape PR objectui#9236 used for ListView, so the canonical groupByField wins instead of the stray key riding restKanban into the trailing spread. Pinned with the distinguishing two-different-lane-names fixture in a new ObjectView.strayGroupByLane-9242.test.tsx (9 arms), plus a minor changeset carrying a BREAKING note that this re-points the lane of already-stored views that never passed a validator. The card's ruled direction (decision batch #117 item 5, option B) was applied, not re-opened. Four faces left untouched as instructed: the contract half, the live kanban.groupField alias, groupBy on the generated node, and ListView.", "tests": "All runs measured the committed bytes: working tree clean vs HEAD 41d1ebc5d, remote tip identical. ABLATION LEG, run in the seat's stronger pin-first form -- the pin was written and run BEFORE ObjectView.tsx was touched, so the unmodified arm is the REAL BASE TREE (96919a459, git status empty) rather than an injected mutation, which is why there is no on-disk mutation proof or restore leg to report: none existed. Direction predicted then observed. RED leg on untouched base: 'Tests 4 failed | 5 passed (9)' -- the 4 override arms failed BY NAME (AssertionError: expected 'LANE_FROM_STRAY_GROUPBY' to be 'LANE_FROM_CANONICAL'; and twice expected 'LANE_FROM_STRAY_GROUPBY' to be 'status'), all 5 CONTROL arms GREEN. GREEN leg after the one-key repair: 'Tests 9 passed (9)'. The asymmetry (controls green in both worlds) is what shows the controls are not carrying the override arms. INSTRUMENT FAILURE CAUGHT AND FIXED, not read as an answer: the first measurement came back shifted by one fixture -- the lit control groupByField-alone answered 'status' -- because the helper lacked cleanup() between renders and stale mounted views kept pushing into the spy. Harness fixed, every reading re-taken, cleanup() pinned as load-bearing in the test. THE ARM MEASURED RATHER THAN COPIED (the card's explicit instruction): this branch floors the lane at the LITERAL 'status', where ListView floors at detectStatusField(objectDef). Measured with every lit control firing -- stray-alone goes to 'status' after the fix, and still 'status' against an object that declares NO status field, where the twin would answer undefined. Both rows pinned. BLAST RADIUS (a rendered node moved, so not package-scoped -- objectui#9273): pnpm exec vitest run packages/plugin-view/ examples/schema-catalog/ gave 'Test Files 69 passed (69) / Tests 2478 passed (2478)', VERDICT command-exit 0 from the shared verify lock wrapper. GATES, hand-derived from package.json + .github/workflows/ since objectui has no dispatch-gates.mjs: check:vi-mock-specifiers, check:vi-mock-inherit, check:vi-mock-override-shape, check:test-path-roots, check:control-bytes, check:new-line-citations, changeset:check, check:changeset-claims, check-changeset-presence.mjs -- all exit 0, each read from its own printed verdict line, never a bare dollar-question. eslint on both changed files: 0 errors. NOT MEASURED: @object-ui/plugin-view type-check -- reason: the shared verify lock was never acquired across FOUR attempts (~26 min cumulative, slot parked and stamp kept each time); holder throughout was pid 16073, still held at 1205s, running another seat's vitest over packages/react packages/plugin-detail packages/app-shell packages/components packages/fields examples/schema-catalog apps/console. The check genuinely needs the lock: plugin-view's tsconfig drops the root paths (objectui#2915) so deps resolve through built .d.ts, and 5 of 8 dep dists are absent here, requiring a closure build first. Deliberately NOT narrowed by piling an unlocked build onto a box already carrying a 20-minute suite, and deliberately NOT dressed up as green. CI runs this family.

I hit exactly this while measuring this card (first reading shifted by one fixture, a lit control answering the previous row's question). NOT filed because it is an observation, not a reproducible defect: in the one test that calls the helper twice, both nodes carry conditionalFormatting undefined regardless of which is returned (objectui#5248 is why the top-level key never reaches the node), so the assertions answer correctly today and I can name no failing probe against that file. Recorded because the harness shape is copied across plugin-view's suite (this card's pin copied it too) and the failure mode is silent. Likely next person to hit it: whoever edits kanban conditional formatting or adds a second renderKanbanView call to an existing it. The new pin carries cleanup() with a comment marking it load-bearing, so the corrected shape now sits in the same directory. Handing the filing decision to the PM rather than filing an observation.", "noted, not filed: I checked the three prose sites that this change could have falsified — packages/types/src/zod/objectql.zod.ts, packages/app-shell/src/views/ObjectView.tsx, and ObjectView.kanbanGroupByRetired-8213.test.tsx. All three are scoped to ListView and remain accurate, so no prose repair was needed. Recorded only so the reviewing seat knows the check was run rather than skipped." ] }Carrier
