Methodology.

The four content types

A · Internal reference

A short entry pointing readers to an existing Closelook asset. No external trigger. Used when a page updates, a new index constituent is added, or a lab feature ships. 40–80 words, direct headline, always links to an internal page.

B · Product signal

Anchored in a Closelook proprietary index or lab signal. Two sub-types: B1 — editorial signals written or curated by Thomas, occasionally LLM-drafted with review; B2 — pure mechanics generated by an agent when a numeric threshold fires (new all-time high, sector-rank change, regime flip). B2 contains no interpretation — just observable facts tied to our own indices.

C · Event trigger + grounded generation

A verifiable event fact from a structured data endpoint (earnings calendar, fundamentals, economic calendar) triggers an agent that generates the entry exclusively from loaded Closelook data — sector performance, constituent row, index weight, framework layer. The external fact is one sentence with primary-source attribution; the rest is ours. See the grounding contract below.

D · Scheduled recurring

Fixed editorial moments at specific clock times — Asia Wrap, Pre-US Setup, US Close Wrap — giving the channel a rhythmic spine. Template- driven with light review, built from today's index closes and window- specific context.

The grounding contract

Type C and B2 entries are generated by an agent, and there are failure modes — hallucination, copied prose, fabricated numbers — that would kill the channel's entire premise. The grounding contract is the enforcement layer.

Before an agent writes, it sees: (a) one trigger fact extracted from a structured data endpoint, (b) a JSON bundle of the specific Closelook rows it is allowed to cite. The system prompt explicitly forbids fabricated numbers, names, dates, or quotes outside that context.

Before anything is published, the output passes a validator: every number in the body must appear verbatim in the input context, every ticker must be in the input, every hyperlink must be a Closelook-domain URL, and any external attribution must cite a primary source — company, exchange, regulator — never the data vendor. A failing draft is retried once; a second failure sends it to the review queue and is never auto-published.

Why not a news feed

Standard financial news exists on hundreds of sites, and copying it dilutes Closelook's positioning. Tape solves a different problem: turning market events into entries into our own pages. No external article prose enters Tape — ever. External signals are triggers only; content is generated from Closelook's own structured data.

Cadence

Tape runs Monday through Friday. No weekend publishing. Multiple entries each trading day — more during active market windows, quieter overnight. Some nighttime hours will have no entries at all. That is by design. The real market tape goes quiet too.
