## Purpose

Canonical specification for permalink-targeted-image-refetch requirements synced from OpenSpec change deltas.

## Requirements

### Requirement: Admin image refetch supports permalink targeting
The admin image refetch command SHALL support a permalink-targeted execution mode for deterministic single-article remediation.

#### Scenario: Refetch by permalink
- **WHEN** an operator runs refetch-images with a valid permalink target
- **THEN** the system resolves permalink identity to the matching article
- **AND** executes image refetch for that target without requiring batch mode

#### Scenario: Invalid permalink target fails clearly
- **WHEN** an operator provides a malformed or unresolved permalink target
- **THEN** the command exits with actionable error output
- **AND** no article image is modified
