AFK: workflow_dispatch to open a single-rule AGWG publish PR

[WilcoFiers]

Parent

#60

Type

AFK for the workflow. Requires W3C write access (HITL secrets). Changelog authoring is #73, not this ticket.

What to build

Wire a workflow_dispatch (act-board and/or CG) that takes a single ruleId and the confirmed changelog (same contract as #64: YAML file in the repo or equivalent, not a free-text dump of git subjects). Run the extended approve-rule path and open one PR on w3c/wcag-act-rules for AGWG review.

Do not batch rules. Do not auto-open tens of PRs on the first board run. No “open all reviewable” in this ticket. Weekly board sync must not call this.

The intended way to produce the changelog and trigger this is the skill in #73 (confirm, then dispatch or run locally). This ticket is the mechanical “open one PR” wiring.

Acceptance criteria

• Dispatch with ruleId + changelog opens or updates exactly one PR for that rule
• PR body is usable by AGWG (the confirmed change list, not classifier commit subjects)
• Opening the PR makes the board Status In review once PR detection (AFK: Map open wcag-act-rules PRs to In review #66) is live
• Documented that batching is intentionally unsupported
• Documented that weekly sync does not open PRs

Blocked by

• AFK: Extend approve-rule for re-approval, one branch per rule #64
• AFK: Map open wcag-act-rules PRs to In review #66 (so In review is detected)
