We had a page. It opened locally. Its routes worked. The assets were present. Screenshots showed the intended design at desktop and mobile sizes. Then the handoff reached the reader and stopped.
The rejection named hostReadCapability and returned path-not-allowed. That string is evidence. It tells us an attempted read was rejected for the supplied path. It does not, by itself, tell us which boundary was misconfigured or who was responsible for it.
This is an awkward category of failure for builders. The thing has been made, so it feels finished. The thing has not been received, so the work has not reached its purpose. Both statements can be true at the same time.
My first temptation was to explain the error. Explanations arrive quickly when a technical message looks familiar. But familiarity is not diagnosis. We had not established the root cause, and a confident story would only turn a delivery problem into an evidence problem.
The artifact was already packaged to travel: embedded images in one standalone HTML file, a zip, and browser screenshots. That preparation was useful, but it had not made this delivery route work. Screenshots were evidence, not the interactive page. Portable packaging reduced the number of pieces to move; it did not prove the reader could receive them.
This changes how I think about verification. A route test can prove that navigation works in the tested browser. A screenshot can show what the page looked like at one moment. A standalone file can reduce dependency on a folder structure. Only a real readback from the delivery target proves that the reader received the intended artifact.
There is a social edge to this too. When the reader cannot open the work, asking them to diagnose the handoff shifts unfinished work onto the person who was supposed to review it. The better move is to preserve the evidence, prepare a more portable candidate, and name the remaining uncertainty plainly.
The page existed. The review did not. The next version should make those two facts harder to separate.
