A signal is a structured takeaway drawn from the most strategically relevant parts of a source. It may be a whole short article, a five-minute exchange from a two-hour podcast, or the one finding that matters in a research paper. Gildea processes signals daily, prioritizing what materially changes the strategic picture.

​
Signal scope

The title, url, and published_at fields point to the full source, but the decomposition (central statement, arguments, and claims) reflects only the extracted segment. So when a podcast signal’s statement reads narrowly, that is expected: treat the decomposition as authoritative for what the signal covers, and the source metadata as a pointer to where it came from.

​
What gets ingested

Gildea ingests from a curated set of 500+ sources across these formats:

​
Two types of signals

Every signal is classified by content_type into one of two kinds:

​
Event signals (content_type: "event")

Key events sourced from global reporting and first-party announcements.

​
Expert analysis signals (content_type: "analysis")

Expert analysis from leading researchers, operators, investors, and analysts who explain what the events mean.

​
The unit model

Signal detail is a flat list of verified units, the fundamental atom of Gildea’s data model. Every unit shares one shape, whether it comes back from signal detail or from search:
role is the single axis that says what a unit is: Reconstruct prose by role: concatenate the thesis (or synopsis) units in order for the central statement; group argument units by argument_id, in order, to rebuild each argument as a paragraph. Units come back grouped by role (thesis/synopsis → arguments → claims) in document order. List position is the order; there is no separate index field. Every unit:
  • Has passed verification: only verified units are served (see Verification).
  • Carries its cited evidence_preview snippets by default.
  • May carry verification: { "human_reviewed": true } when a human reviewer signed off (omitted otherwise).
  • Is retrievable through semantic search (see Search).

Signal card vs. signal detail

The list endpoint returns lightweight signal cards: identity, classification, a depth signal (verified_unit_count), and the central statement served whole: a thesis field on analysis signals, a synopsis field on event signals. The detail endpoint returns the full flat units[]: every verified unit with its evidence (included by default). Concatenating the thesis/synopsis units reproduces the card’s statement, so the two never disagree. Pull cards from the list endpoint for discovery; fetch detail when you need the verified atoms.
