## Source discovery: Capitol Hill community markets, recurring outdoor events

### Results

One new source added: On the Block Creative Marketplace as a recurring YAML.

#### Added

- ✅ Added: On the Block Creative Marketplace — recurring YAML (`sources/recurring/on-the-block-capitol-hill.yaml`) — 2nd Saturday monthly June–September, 12pm–6pm, 11th Ave between E Pike St and E Pine St, Capitol Hill. Pattern confirmed across 2024–2026. Build verified: 1 upcoming event (2026-07-11).

#### Not Viable / Already Covered (sources investigated this run)

- ❌ Seattle Street Food Festival (`seattlestfoodfest.com`) — Domain now redirects to an unrelated site; historical date pattern inconsistent across sources (June? July? August?). Cannot implement as recurring YAML without stable domain and verified pattern.
- ❌ Seattle Makers (`seattlemakers.org/events`) — EventPrime WordPress plugin, events only rendered via AJAX; `admin-ajax.php` returns "0" without auth nonce; needs browserbase.

### Notes

On the Block is a 2022-launched community market series produced by local organizers in Capitol Hill's Pike/Pine Arts and Cultural District. No machine-readable feed; the 2nd-Saturday-June-through-September pattern is documented on their site and EverOut listings for 2024 and 2025. Recurring YAML is the correct implementation path.
