Step 3 of RFC-0042's rollout (ADR-0044), built on #103 and #104.

Derived gates (min(availability.until, expiry))

Surface	unlist past the gate	hide past the gate
Entry URL	200	404
Listings, archives, contentList, related	left out	left out
RSS, sitemap, llms.txt, search	left out	left out
Menus, hreflang	kept	gone

• The gate index caps the edge cache at each derived instant, and at the date values of list fields used with now.
• A date ends at the start of the next day in the site's zone.
• Previews show "Ended on …" or "Expired on …".

Guards

• The site Worker reports gates: 2. Until it does, the store refuses a new or changed expiry with gates_unsupported (409); removing one is always allowed. The API, MCP and imports go through this check.
• In auto mode, a publish or release that adds a live entry's derived gate, or moves it earlier, waits for a person (new check code expires).

Theme API (additive)

• ./queries: queryEntries, contentListEntries and friends. GraphSource.queryEntries? / routableEntries?.
• withStructuredData / entryStructuredData: the preset JSON-LD in place of BlogPosting. entryHead is unchanged.
• ContentList supports where and orderBy. Old themes that pass a source's list through get field listings too; the compat test checks this for v0.3.10, v0.4.0 and v0.5.0.

Starter: uses contentListEntries and withStructuredData. Output is unchanged for sites without the new settings.

Benchmark (10,000 entries, median of 10 runs, bench:lists, opt-in)

Path	SQLite CPU	Rows	D1 CPU	D1 rows
Today's scan, no where	53 ms	10,000	100 ms	10,002
Store / API queryContentEntries	124 ms	10,001	176 ms	10,003
Snapshot, per request (published site)	22 ms	0	21 ms	0

The published site is well under the 50 ms threshold. The store, API and MCP path reads the whole collection by construction and is over it. Under RFC-0042 open question 10 that argues for an entry_list_values side table on that path, a separate decision.

Not done

• The workerd route sweep doesn't cover derived gates yet; only the renderer sweep does.
• Studio has no wording for the expires reason yet (step 5).
• renderSectionHtml previews ignore where, as they already ignore filter.

Tests

• astro-renderer: 283/283.
• cloudflare: 54/54.
• agent-runtime: 72/72.
• api and mcp-server pass.
• core-ts: sqlite and D1 pass. Locally the DO tail fails with EADDRNOTAVAIL.
• cli: e2e and the compat test with three themes pass; the full run otherwise passed.

Changeset: minor.
