What

Search engines had little to go on: the home page never said programming language, most descriptions were cut mid-sentence, playground pages were titled by file name, and there was no reference for the standard library at all.

Titles, descriptions, names

• Home: iyi: the programming language for people and their agents; the heading and lead say programming language.
• iyilang is the second name: in the colophon and as alternateName (with iyi lang, iyi programming language) in the JSON-LD. "iyi" alone is a common Turkish word and a party's name.
• Every description is ≤155 characters and every title ≤60; Page.astro fails the build on either. A title that already names iyi no longer gets | iyi appended.
• Lessons carry searchTitle and description in their frontmatter (Error handling in iyi: errors you cannot ignore).
• Playground pages lead with their topic from src/playground/topics.json (Arrays in iyi: a runnable example). A tour step's description is its own first comment line; repository samples get an authored about. A page with no entry, or an entry with no page, fails the build.
• /project/notice/ and /project/conduct/ are noindex and out of the sitemap (third-party / boilerplate text); their titles are no longer Crystal Programming Language.

/reference/

• 110 std/ modules and 31 prelude types, 621 declarations, each with a heading and an anchor.
• Signatures and doc comments are iyi doc output, verbatim (not mod dump --json, which drops reopened types and constants). A module's header comment, which no compiler output carries, is read from the source at the tag.
• npm run record:stdlib writes records/stdlib.json; scripts/stdlib.mjs (in generate) refuses it when the release ships a module it does not cover or a source it was not printed from.
• In the masthead, llms.txt, and budget.json (three new rows).

Gates touched

• release-ref.mjs: requireReleaseCompiler also accepts the 7-digit bracketed hash the release's own binary prints ([2a96530]), so the record can be taken with an unpacked release.
• prose.mjs: doc-comment blocks are exempt. They reach the page as one string from the repository, so the template line-break weld cannot occur, and they contain RFC 6265bis, 0xc0, 1xx.

Verification

• npm run build against a v0.18.0 worktree: generate, prose, links (225 pages), budget all pass; astro check 0 errors.
• Built output: no title over 60, no description over 155, no duplicate titles; sitemap 221 URLs without notice/conduct.
• The description gate failed the build on the old install summary (166 chars) before it was shortened.
• stdlib.mjs rejects a record with a corrupted digest and a missing module.
• /reference/, /reference/std/csv/, /reference/prelude/string/ checked in a browser.
