Shadow reporting: what the answer engines told a reader
Kept by incident.shadow@web-summit.dinis, 11 November 2026, 11:13 UTC
Not a warning service. For warnings follow IPMA and ANEPC. Nothing below is a forecast or advice of ours, and nothing an engine said is a fact here.
What this is
A member of the public no longer only reads the news: they ask an answer engine. So every hour we ask a fixed set of questions, in Portuguese and English, exactly as a reader would (questions.json), keep each answer as data, split it into checkable statements in our own words, and compare every statement with what this site holds from the bodies that decide and warn (the timeline, the decision graph, the warnings).
The idea is the SGit Newsroom's: "The shadow of an article is evidence. Who cites it, what they quote, what they say it says", and "A shadow is not the article" (Sources and their shadows, Dinis Cruz, 25 October 2026). Here the shadow is the one an answer engine casts of the authorities' words: an engine's answer is evidence about the engine, not about the storm. A statement we do not hold becomes a lead to verify at the primary source; it never enters the timeline from here.
| Label | Meaning |
|---|---|
| matches | our record holds the same, from the row named |
| behind us | our record holds something newer or more exact that the answer missed |
| ahead: a lead | not in our record: to verify at the primary source |
| contradicts | our record, or the calendar, says otherwise |
| unsupported | outside our record, general information, or an omission we note |
So far: 1 hour(s) asked, 9 paused (the account that pays the engines was out of credit: a gap, not silence), 23 answers, 90 statements: 46 matches, 11 behind us, 12 ahead: a lead, 7 contradicts, 14 unsupported. Spent on the engines: 0.17 US dollars (the day's limit is 1). Data: runs/ (one file per hour), leads.json, sources.json, cited.json.
What the first hour shows (02:19 UTC, Wednesday)
Our analysis of one round (23 answers, two engines); labelled as analysis, to be tested by the next rounds.
- "Tomorrow" was yesterday's tomorrow. Asked "Is Web Summit on tomorrow?" at 02:19 on Wednesday, Perplexity Sonar answered in both languages for Wednesday (the day the press called "tomorrow" on Tuesday). OpenAI's search model read the date and answered for Thursday. A reader asking after midnight could be told "no" about the wrong day.
- "Aims to proceed" becomes "yes". On Thursday, the organisers' own word is an aim. Two answers gave it as settled ("as planned", "scheduled to go ahead"); one of those rested on the schedule page as it stood before the storm.
- Issued is not in force. Asked what is in force now, the engines listed the red warnings (which start at 09:00 and 12:00) and gave no hours; one gave the rain warning in force at that minute as yellow where IPMA's feed has orange; the only warnings actually in force at 02:19 (orange rain, yellow sea) came third or not at all. One answer reported that two large weather sites showed "no active alerts".
- The 09:00 change got through by one path only. IPMA moved Lisbon's red rain to 09:00 at 21:23 on Tuesday. Asked directly, Sonar had it (through a weather site that relays the official warnings). Asked generally, two answers still said late morning or 12:00.
- Madeira: the previous storm. "What happened in Madeira?" returned Storm Bruna (the weekend) from one engine in both languages and a question back from the other, during a red warning and with 230.5 mm measured in six hours at IPMA's Areeiro station. Asked for the rain by name, Sonar gave 204.4 mm in a day and 188 mm in six hours: behind IPMA's own station values.
- Who they cite. Perplexity Sonar pointed at 150 addresses in 18 answers; 13 were a primary body's own page (the Metro, Web Summit, the city council, an embassy) and none was ipma.pt or prociv.gov.pt, which its search never returned. OpenAI's search model pointed at 12 addresses in 5 answers; 9 were primary (IPMA, ANEPC, the government's order, the maritime authority, Diário da República, the Metro's status page). Fewer sources, closer to the bodies; but it also said the Metro was "running right now" at 02:19, from the operator's status page, when the Metro is shut for the night.
- The Metro's hours. All three Metro answers said yes. None said that at the minute of asking the Metro is closed until about 06:30.
Hour by hour: what a reader was told, against what the authorities had said
Times are UTC (Lisbon is on UTC in November). "The record" is what the authorities had said by our files at the minute of asking.

"Primary" means the host of a body that decides or warns, or of the organiser or operator for its own decision (IPMA, ANEPC, the government, Diário da República, Web Summit, the Metro, the city council, the maritime authority and a few more; the list is in tools/shadow-index.mjs). A count of addresses, not a judgement of anyone's journalism.
How it is made
- tools/shadow-ask.mjs asks through the team's one wrapper for model calls (every call recorded, a daily limit). The engines are named because they are the subject: Perplexity Sonar (
perplexity/sonar, OpenRouter); OpenAI GPT-5 mini with web search (openai/gpt-5-mini, OpenRouter (the web plugin, the provider's own search)). - The answers' full text stays in the raw store outside this repository (each answer here carries the record's name and sha256). This page and the run files hold our own words, fragments of a few words in quotes, and the addresses the engines gave.
- Addresses on social networks are kept as the host only: a post there may be a private person's.
- The splitting into statements and the labels are the shadow desk's reading, by hand, each hour. A label is our analysis: check it against the row it names.
- A news API for headlines and links: news-apis.md.
