Scenario loader refuses an operation its persona cannot reach (row scope, hidden field or object); fix the three cards it catches

epic:#3600#1 · hotlong · session_01Q4EjjPXwX1YfHyKJUh4agu

Filing-gate category: ① defect class with named locations and a proven guard, split from #30770 (report comment 6676516411). Maintainer, verbatim (Claude Code session, 2026-11-06), on routing: 「能交给车队开发的你不要自己开发」. Epic context: objectstack-ai/cloud#3600; this card is the lane's, not the epic's.

Blocked-by: #30770

(Serial: PR #30801 for #30770 edits the crm card and the runner tests this card's branch builds on.)

Problem

A scenario card can declare an operation that a faithful build can never perform as declared: the acting persona's row scope excludes the target row, or the persona hides a field or object the write touches. The run then grades a correct app as failing. #30770 fixed the crm card; the same class exists in three more cards.

The guard is already built and proven

Branch claude/issue-30770-loader-reach-held @ 82b1acd8 (pushed, not landed): a loader refusal that is statically decidable from the card alone (row scope against the seed, hidden objects and fields against the written values). Measured there: refusals.test.ts 48/48 with the rule; ablation (the loader restored to the pre-rule bytes) gives 43 passed / 5 failed, exactly the 5 new reach cases. Resume from that sha.

Cards it refuses today (fix each in this card)

docs/qa/scenarios/invoice_with_line_items.json, ops add_line and line_without_product: sales_rep hides invoice_line.unit_price, which the create writes.
docs/qa/scenarios/project_with_tasks.json, ops add_task and task_without_title: contractor hides task.estimate_hours, which the create writes.
docs/qa/scenarios/travel_expense.json, op employee_approves_colleague: the target approval_step row is outside employee's row scope. The guard expects RECORD_NOT_FOUND (the platform answers a by-id write on an unreadable row with not-found); the card declares PERMISSION_DENIED. Measure once against a booted app whether this decision goes through the by-id data update (→ RECORD_NOT_FOUND) or an approval door that refuses first (→ PERMISSION_DENIED), make the card match the measurement, and make the guard's row arm agree. If the two paths contradict a documented contract, stop and report it instead of choosing.

Use the same moves #30770 used: drop the hidden field from the write, or switch to a persona that can perform it, keeping what each operation was meant to test. Keep each card in its counts band. Also fix packages/qa/scenarios/README.md, which still shows gradeCardOperation(card, 'remove_chen', observed); the operation is now remove_ben.

Any card the devx mid-tier lane lands meanwhile (#30477, #30479, #30481) must pass the guard too.

Reader: the domain:devx lane seat, from pm:queue once #30770 closes.

The loader refuses an operation whose acting persona cannot reach its object, row or written field unless the card declares the refusal a faithful build gives; four of the five operations it catches on main are fixed by dropping the hidden field from the write (invoice_with_line_items add_line / line_without_product, project_with_tasks add_task / task_without_title), and the README example names remove_ben. travel_expense employee_approves_colleague is left as on main: the booted-app measurement found the two doors contradict a documented contract, so per the card it is reported for a ruling (open_questions) instead of chosen.

Cost: the op becomes 'employee approves its own claim' (renamed id + one line in test/travel-expense.test.ts, one dev commit, S). Every pending step in the seed is on someone else's claim, so the ask names an already-decided step unless the seed gains one pending step on an employee claim, which moves computed truths (M, recheck counts band).",

State: pm:dispatched removed in this stroke. Delivered: the scenario loader refuses an operation its acting persona cannot reach (checkReach), and every card in the library loads with no refusal. travel_expense op 4 is employee_approves_own_claim per the maintainer's ruling (option A, 2026-11-06T11:08Z). Left for a later card, as the ruling says: coverage of a write across row scope. Related platform finding #30848 closed by PR #30878.
