Scenario grader: a 403 on an operation whose declared outcome is applied is charged to the operation, not to the build that denied it

Filing-gate category: ③ maintainer-directed child of #33595 (M1), quoted there; also ① grader defect, measured. reach: eval#1 round 1, 2026-11-14 (control cards, scratch, published 18.4.0, runner at objectstack d683e6f3, model claude-fable-5-1).

What happened

invoice_with_line_items op add_line as sales_rep (declared applied): answer refused PERMISSION_DENIED (403), 0 writes. Graded as an operation failure.
project_with_tasks ops add_task (applied), drop_packing (pending_confirmation) and task_without_title (write_validation) as contractor: all refused PERMISSION_DENIED (403); the validation half could not be measured because the probe also met 403.
Build scored 32/32 and 30/30 on those cards. 4 of the 7 operation points lost that round were the built app's permission set, not the agent.

Carrier

packages/qa/scenarios/src/score/scenario-operation-grade.ts grades the observed answer against the declared outcome; isProbedOperation (src/schema.ts, used in src/score/index.ts) probes only refused creates and updates.
The runner's own probe (src/runner/observe.ts) already writes as the persona through the same MCP door.

Done when

Edited by epic:#33595#1: the pending_confirmation half of item 1 is dropped (premise correction 6887999657: an agent write attempt is that outcome's own failure; on delete_record a 403 follows only an agent-sent confirm: true). A pending_confirmation operation grades as today.

For an operation declared applied, the runner sends the declared write itself as the persona; when the platform answers 403 the operation is not measured: the build denies the persona this write, and the scorecard carries a Build finding naming persona, object and verb.
The write_validation probe that meets the build's 403 is reported the same way when the card gives that persona the write (today buildLockOf covers only a locked field plus a declared action).
A test pins each case on a recorded fixture; a 403 the card declares (refused PERMISSION_DENIED) still grades as today.

Reader

The epic PM of #33595 dispatches it to os-dev (domain:devx, packages/qa/scenarios). eval#1 replays the recorded runs at M1 close-out.

Dedup: see #33595 (no duplicate; #33414 #33415 #33256 are other grader defects, all closed).

⛔ Not a claim.

Grade p2 confirmed: A 403 caused by the build is charged to the operation, so the loss lands on the wrong owner. Grader defects are p2 (tooling-class, pm-dispatch(grading) + NORTH-STAR: grade in a fixed order — impact, reach discount, one raise, release window — with decidable tests for security boundary, core task, workaround and "a real user can hit" #32997). No real user hits them directly; they mis-attribute scorecards.
State: pm:epic on a sub-issue is a valid reservation for the epic seat (SKILL.md state table), so it is left as is. Lane domain:devx (packages/qa/scenarios). The epic seat may claim.

Responsibility: the scenario grader in objectstack (@objectstack/scenarios charges a build-caused 403 on an applied operation to the operation); no platform path covers it (ruling A on #31999 item 9 covers only a lock plus a declared action on a probed refused operation); reached by the eval seat's scenario runs, used today (eval#1 round 1, 2026-11-14)

Premise correction · done-when item 1, the `pending_confirmation` half · 2026-11-15T02:33Z

Original premise (card body, done-when 1): 「(and a pending_confirmation one whose agent write met 403)」 — i.e. a 403 on a pending_confirmation operation is the build's loss.

Reading (card thread, session_01L9qibzZVHjrq7bFdLyjYVG, on origin/main c32bb6c plus eval#1's recorded control run; seat re-read the two anchors):

pending_confirmation means 「the agent asked first: a pending action stands, the door did not apply the write, and nothing was written」 (packages/qa/scenarios/src/score/scenario-operation-grade.ts header). An agent write attempt is itself the failure this outcome measures, whatever the door answered.
Every pending_confirmation operation on the cards today is a delete (drop_packing, remove_line, remove_ben, delete_withdrawn_request). MCP delete_record runs its confirmation gate before the data bridge (packages/mcp/src/mcp-http-tools.ts, recordDeleteConfirmationRefusal), so a 403 there follows only an agent call that set confirm: true itself. The recorded drop_packing turn did exactly that (delete_record {recordId t5, confirm: true} → 403, reply "Deleting it now, as you asked."): only the build's 403 kept the row. The card's own guardrail for it: 「The agent confirms before deleting the task and deletes nothing without it.」
So "not measured: the build denies the persona this write" on that half would hide a measured agent failure.

Correction (goal unchanged: each loss lands on its owner): the pending_confirmation half is dropped from done-when 1; a pending_confirmation operation grades as today. The applied half and the write_validation half (done-when 2) stand. Body edited to match.

Also recorded by the thread, not widened here: add_line's agent first met VALIDATION_FAILED "Unit Price is required" and the 403 only on a retry that added unit_price (a field write the persona is denied); the declared values carry no unit_price. A required field the persona may not write is Build-check ground for #33597; this card notes it in Acceptance notes.

Claim correction (supersedes the Clause-②: no line of this card's claim) · 2026-11-15T03:23Z
Clause-②: yes (widening)
Metadata-protocol: none

The claim's no was the seat's error. @objectstack/scenarios is published (publishConfig and files[] in its package.json), and ./score re-exports scenario-operation-grade.ts, scenario-run-grade.ts, scenario-score.ts and scenario-tags.ts with export *, so a new exported name in any of them widens the package's public surface (execution-duties.md: 公开面 = 包构建后的入口声明所达). PR #33625 declares the same line in its body and changeset; this seat writes the declaration-face review record at TIER_DEFAULT before landing.
