Methodology
A concise account of what the briefing selects, what its labels mean, and where editorial judgement enters the process.
Selection
Feeds are swept on a fixed window. Candidate stories must have a usable web address, fall within that window, and clear an editorial relevance threshold. The daily issue is intentionally selective rather than a complete index.
Event clustering
Reports about the same underlying event are grouped before ranking. Same-publisher duplicates and community mirrors do not inflate the independent-outlet count. One representative story leads; useful alternate reports remain as coverage links.
Evidence
Every item keeps a raw evidence kind and displays its public label: Primary source, Independent reporting, Newsletter analysis, Research paper, or Community signal. Coverage is shown separately as Single-source or the number of independent outlets.
Source balance
Source weights are a prior, not a guarantee of placement. The shortlist is stratified and capped so one prolific outlet, lab, or paper feed cannot crowd out the rest of the briefing.
Model role
A language model scores and edits a bounded slate: it does not browse freely, invent sources, or change source links. Deterministic checks enforce dates, clustering, diversity, safe links, and fallbacks when the model is unavailable.
Dates and times
Published, Updated, and Posted follow the timestamp
kind declared by the publisher or community source. Explicit instants are displayed in
Europe/Oslo time while the exact source ISO value remains in the page’s time
element. Date-only values never gain an invented clock, and a wall clock supplied without
a timezone is labelled as such rather than converted into a guessed instant.
Story images
Article thumbnails are fetched server-side, re-encoded as local WebP files without embedded metadata, and never hotlinked from publishers. When no safe local thumbnail is available, the card uses local category artwork instead.
Daily issues and rolling roundups
The dated daily issue is canonical and immutable at its archive URL. Weekly and monthly pages are rolling 7-day and 30-day rankings; they are refreshed in place and are not added to the daily archive or digest feed.
Corrections and contact
Report a correction with the issue date, headline, and source URL through the same contact channel by which you received this briefing. Confirmed material corrections are applied to the canonical dated issue. Source-inclusion requests are reviewed for relevance, feed reliability, and transparency; payment does not buy placement.
