Table row action targeting: permission default deny · case 01

The table permission default deny result violates the stipulated table row action targeting contract.

Verified by executionVariant 1 · 8 checks per implementationDownload source bundle ↓JSON ↗

ROOT CAUSE

The permission default deny decision uses "permissions.get(k,{}).get(action['id'],True)" instead of "permissions.get(k,{}).get(action['id'],False)".

THE FAILURE

The permission default deny decision uses "permissions.get(k,{}).get(action['id'],True)" instead of "permissions.get(k,{}).get(action['id'],False)".

Unsuccessful approach: The attempted repair 'bool(permissions.get(k,{}))' still loses a required part of the table contract.

Case contract

A row action uses current row order, bulk selection only when the clicked row belongs to it and the action permits bulk, optional visible scope, default-deny per-action permissions, atomic busy/permission rejection, explicit empty scope, confirmation policy, and per-row revision snapshots.

Why this case matters

An offline table UI model isolates table row action targeting, including adversarial row/column relationships.

HELD IN THE MEMBER ARCHIVE

The verified repair and its recorded checks are member-only.

This mechanism has 8 recorded checks per implementation. The open-access tier publishes the failure and the unsuccessful fix; the repaired source that passes every check, and the observations that prove it, are available to members.

Every case sharing this mechanism uses the same contract and the same repair, so this one record is held back for all of them.

Member access is invitation-based. Sign in with your invited account to inspect the repair.

Verification & scope

Source row IDs are unique; permission maps hold per-action booleans and revision snapshots are explicit. Deterministic offline table UI model; no browser, DOM, framework, or standards conformance is claimed. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.

Observations recorded using Python 3.12.14 at 2026-09-29T14:43:09.209364+00:00.
