How this classification was derived · the three gates
Gate 1 · Reachability
degraded

Crawl policy is unknown — robots.txt is absent or could not be fetched.

Gate 2 · Legibility
Not evaluated

Awaiting Gate 1 — legibility is not evaluated when the domain is unreachable.

Gate 3 · Authority
Not evaluated

Awaiting Gate 1 — authority is not evaluated when the domain is unreachable.

Primary constraint: Crawl policy is unknown — robots.txt is absent or could not be fetched.

AI systems can't reliably reach typescriptlang.org's content.

Recommended next steps
1.Add specific verifiable claims to key pages

Expected impact: Restores crawler access

2.Add publication dates

Why these recommendations?

Robots.txt is blocking AI crawlers from accessing this site.

• No structured data (JSON-LD / schema.org) — machine-readable metadata is absent.

• No Organization schema — entity identity is not machine-asserted.

• No author attribution — content lacks attributable provenance.

• Add specific verifiable claims to key pages: AI systems extract attributable facts — named figures, dated events, quantities. Generic statements do not register.

• Add publication dates: Retrieval-augmented AI pipelines filter by recency. Undated content is deprioritised in freshness-weighted retrieval.
