docs+skills: three authoring pages still say a system-elevated hook, action body or flow bypasses every check; the four identity-assignment objects are refused (system-context.mdx row 1b, #25653)

Filing gate ①: a product defect with a named location. These are author-facing pages that state a rule the runtime no longer keeps. This is a follow-up owed by landed work (#25653's run-time half on main, and its save-time half in PR #26430). Filed by domain:spec seat 1 (#6017, session session_01WGufzfhobWEgUUrjz4rrbh) from contract review 6433419685 item 12. ⛔ Not a claim.

Business reason: an app author reads that runAs: 'system' (or an action body) is "full-access" and "bypasses row- and field-level security". They write a hook or action that assigns a position, a permission set, an invitation or a membership, and it is refused at run time (PERMISSION_DENIED). After PR #26430 lands, it is also refused at save time when the body names the object as a literal. The pages tell the author to expect the opposite of what happens, and they omit the remedy the refusal names.

Reader who acts: the lane triage names. The items span two lanes: content/docs/** and skills/** (Tier H). This card carries no domain:*; triage splits or routes it.

Where

At origin/main, read 2026-10-27:

content/docs/automation/hooks.mdx:157: the 'system' row says "elevated: a full-access, RLS-bypassing system principal. Row and field permissions do not apply…"
content/docs/ui/actions.mdx:443-445: "An action body and a registered handler both run elevated: ctx.api and ctx.engine carry isSystem, so they bypass row- and field-level security by design…"
skills/objectstack-automation/SKILL.md:164-191: the runAs: 'system' guidance ("the trusted-writer channel", "Elevate the write, not the flow") never says that writes to the four objects are refused.

The rule is already written once, correctly, at content/docs/permissions/system-context.mdx row 1b. Each page above owes one sentence plus the link: a governed write (insert, update, delete, transfer, restore, purge) to sys_user_position, sys_user_permission_set, sys_invitation or sys_member from app-authored system automation is refused, and the remedy is the delegated-administration door that the refusal message names. The skill also owes an eval prompt per its package's convention.

Also carried here (from the #26430 dev report, out of that card's scope)

FlowSchema has no save-time twin of feat(spec)!: refuse at save a system hook or script action body that writes an identity-assignment object #26430's body check. A runAs: 'system' flow's data node that names one of the four objects is refused only at run time (18.flow-run-as-system-identity-assignment-write-refused is the run-time entry). Decide whether a save-time refusal is owed. That would be a spec narrowing, so it moves to the spec lane if yes.
The four-object set and the prescription text are duplicated between packages/spec/src/identity/identity-assignment-body-writes.ts (from feat(spec)!: refuse at save a system hook or script action body that writes an identity-assignment object #26430) and packages/plugins/plugin-security/src/flow-system-identity-write-refusal.ts. One should import the other, so the two cannot drift.

Dedupe: an issue search for "system elevation bypass docs identity-assignment hooks.mdx actions.mdx" (open and closed) found no card naming these pages. #25653 and #26430 name the spec and runtime halves only.

⛔ Not a claim, ⛔ not a dispatch.

Lane: domain:devx for the three content/docs/** pages (hooks.mdx:157, actions.mdx:443-445, and the third the body names). The skills/** lines go as a follow-up card the PR names in its Skills-docs: line ([Decision] pm-dispatch: which PRs owe a Skills-docs: line (the #26184 audit Part B rule draft) — protocol-kind only, protocol-kind plus narrowing, or not adopted #26369 B), because skills/** is Tier H, domain:skills. p2 stands. The docs state the refusal and its remedy as system-context.mdx row 1b states them. ⛔ The pages describe the refusal, not a way around it (skills: five principle gaps the #9296 wave exposed in checklist-test / checklist-author / dogfood-verification #9387).

Premise: on main the run-time refusal of these writes has landed (#25653), and system-context.mdx row 1b states the rule correctly (the dev re-reads both and states the save-time half only if PR #26430 has merged)
Serial constraints cleared: #26442 (this seat) regenerates the census table of system-context.mdx; this card only links to row 1b
