Source Highland55 Urbana connection via primary instruments (recorder, ODOD, CRA/PILOT)
## Context **Highland55** is the only Urbana-specific data-center signal in the corpus, but it exists solely as a one-line entry in `docs/COURSE.md` (line 117) tagged **`[open]`**: *"Thor Equities / Thor Van Wert / Highland55 (Urbana, Van Wert); CyrusOne; Platon Investments / Dynamo Ventures … corridor `[open]`; no in-corpus document yet."* A repo-wide search confirms Highland55 appears in exactly three corpus locations — `COURSE.md`, and the prior Van Wert research run's `findings.md` and `manifest.yaml` — never in a primary instrument or extraction. The site profile's `facility` field is `None` `[open]` (sites.py line 1674) and `facilityStatus("urbana") = "investigation"`. The `self-research` step that would have generated data-center seed proposals **errored** (`1 validation error for ProposalDrafts`), so the inferential entity layer is also empty. ## Acceptance Criteria - [ ] At least one primary instrument is ingested and extractable via `list_documents` for `urbana` or `champaign` — acceptable forms: Champaign County Recorder deed, ODOD/JobsOhio announcement, CRA/PILOT agreement, NPDES application, or zoning instrument tied to Highland55 or a Thor Equities entity. - [ ] **Or**, if no instrument is found after a documented search effort, Highland55 is formally retired from the Urbana register in `COURSE.md` and `sites.py` with a `[not found – retired YYYY-MM-DD]` tag. - [ ] The Highland55 register is kept **separate** from the Allen-County/Lima Bistrozzi land-assembly graph (no cross-reference unless a filed instrument bridges them). --- _Proposed by `bosc onboard urbana --research` (Phase 5; onboard-urbana-urbana-data-center-activity-recei-2026-06-21).
