[magurotuna]

Register Shamir's Secret Sharing and Checking for directory existence in the examples catalog so their pages appear in the sidebar/landing page. Also aligns sss.ts @title with its catalog label.

Model verdict: APPROVE (informational only)

Formal review policy did not authorize an authoritative event (required_checks_missing).

No blocking findings.

Verified the two new catalog entries in examples/_data.ts are correct: both referenced scripts exist (examples/scripts/sss.ts, examples/scripts/checking_directory_existence.ts), and their hrefs (/examples/sss/, /examples/checking_directory_existence/) match the page URLs generated by examples/index.examples.page.tsx (/examples/${label}/). Both category values are valid members of categoryOrder, so they render in the sidebar (_data.ts:2040). Entry order doesn't matter since items are alphabetized at build time. The @title edit in sss.ts is a JSDoc tag that now matches the catalog label and has no typecheck/runtime impact. Pure data/doc change with no error handling, logic, or test coverage implications.

Model verdict: APPROVE

No blocking findings. The effective base/head change at current head dd6295f is identical to the previously reviewed change (the new head only merges main into the branch). Re-verified: both catalog entries reference scripts that exist (examples/scripts/sss.ts, examples/scripts/checking_directory_existence.ts); their hrefs (/examples/sss/, /examples/checking_directory_existence/) match the URLs generated by examples/index.examples.page.tsx; both category values are valid members of categoryOrder so they render in the sidebar; and the @title edit in sss.ts is a JSDoc tag now aligned with the catalog label, with no typecheck/runtime impact. No prior findings remain open.
