Subject: [PATCH] Add university-extension variety trials: Illinois VT + Iowa
 ICPT + Ohio OCPT (+123 trial docs)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Independent third-party performance data — land-grant programs that test every
entered brand side-by-side with replication + LSD stats. This is the legitimate
way to get Pioneer / DEKALB / Brevant / Channel performance the corpus can't
scrape directly (data_type=trial, results[] shape; falls through the trial
chunker).

- illinois_vt_trials (30 docs, 1,392 rows) — U of Illinois VT. Per-region XLSX
  (openpyxl), corn + soy + WHEAT, 2024+2025. Rich per-site agronomic metadata;
  corn-following-corn vs -soybean kept distinct.
- iowa_icpt_trials (24 docs, 674 rows) — Iowa State ICPT. ASP.NET GridView
  (viewstate postback for year/district), corn + soy by district x season.
- ohio_ocpt_trials (69 docs, 4,647 rows) — OSU/CFAES OCPT. Report PDF
  (pdfplumber; per-site column groups split by header Yield-token count +
  x-coord footnote bucketing), corn + soy per site, 2024+2025.

91 distinct seed brands across the three; majors confirmed present in the
independent rankings: DEKALB 395, Golden Harvest 249, Channel 241, NK 212,
Xitavo 135, LG 103, Pioneer 88, Asgrow 59. (A brand only appears where it
ENTERED a given program — e.g. Brevant not in Iowa, DEKALB/Channel not in
Illinois — true negatives, not parse gaps.)

- rag/chunk.py: gated `include_region` on _render_gh_plot_chunk; the 3 university
  sources route through it so the region/district is in the embedded chunk +
  labeled "variety trial (cross-vendor, independent third-party)". Existing plot
  sources (gh/lg/agrigold/proharvest) unchanged.
- requirements.txt: openpyxl (Illinois XLSX; scrape-time only).
- sources.json + README/CLAUDE/lessons: registered + attributed; lessons
  trial-data + Pioneer entries updated (Pioneer/DEKALB performance now available
  indirectly via these trials).

Validation: all 123 chunk via rag.chunk.chunks_from_trial (0 errors), 0
out-of-range yields, 0 dup keys. Public land-grant data; attribution recorded in
each tos_note. CI rebuilds the index from the committed corpus.

+"""University of Illinois Variety Testing — cross-vendor yield trials.
+
+The University of Illinois Crop Sciences Variety Testing program
+(``vt.cropsci.illinois.edu``) is a long-running, independent land-grant
+testing program. Seed companies pay an entry fee to enter hybrids /
+varieties; UIUC plants them in replicated regional trials and publishes
+the results. Because the program is third-party and cross-vendor, a
+single regional table ranks Pioneer / Brevant / DEKALB / Channel /
+Burrus / Stine / Viking and dozens of others head-to-head — the
+legitimate, independent way to get major-brand performance the
+single-vendor corpus can't scrape directly.
+
+This is a ``data_type: "trial"`` source (NOT variety identity). It emits
+the same per-site cross-vendor sidecar shape as ``gh_plot_reports`` /
+``agrigold_plot_reports`` / ``proharvest_plots`` (``results: [{rank,
+brand, product, traits, metrics}]``), so it falls through to the shared
+``_render_gh_plot_chunk`` renderer in ``rag/chunk.py`` with no chunk.py
+edit. The published table lists entries alphabetically by company, so we
+**synthesize ``rank`` by sorting on Yield descending** (highest yield =
+rank 1) per document.
+
+Data layout (verified Nov 2025):
+  - Static XLSX (+ PDF) per region per year at WordPress upload URLs.
+    The month segment of the upload path varies (``/2025/11/``,
+    ``/2025/12/``, ``/2025/07/`` for wheat), so we DISCOVER the .xlsx
+    hrefs by fetching the /corn/, /soybeans/, /wheat/ index pages — we
+    never guess URLs.
+  - Corn regional tables: ``Company | Name | IST1 | GT2(+spill) | HT3 |
+    Relative Maturity | Yield bu/a | Moisture % | Lodging | <per-site
+    cols> | 2-yr Avg | 3-yr Avg``. Per-site metadata lives in a separate
+    "Trial Info" sheet (regional tables) or in trailing columns
+    (single-site CFC tables).
+  - Soybean regional tables: ``COMPANY | NAME | Herbicide Trait1 | ST2 |
+    Yield bu/a | Maturity Date | Lodging | Height | <2yr/3yr Yield> |
+    Protein @13% | Oil @13%`` with the per-site metadata block in
+    trailing columns.
+  - Wheat regional means tables: ``Company | Variety | ST1 | Yield |
+    Yield Rank | Test wt. | Height | <per-site Yield/Test wt.> |
+    Maturity date | Jointing time | FHB Score | FHB Category``. Wheat
+    publishes its own Yield Rank, which we honor.
+
+The variety table sits below a 2-4 row header band (a group-header row,
+a column-name row, and a units row). Columns are positionally stable
+within a sheet (multi-word brands like "Viking | Blue River" live in a
+single COMPANY cell), so we anchor on the header row that carries
+"Company" + "Name"/"Variety" and map the metric columns from the
+column-name + units rows. The leftmost "Yield (bu/a)" column is the
+**regional** yield — the primary metric.
+
+Section markers interleaved in the table ("Early RM", "Any RM",
+"Non-GMO Hybrids", "Early MG: 1.9-2.7", "Late MG:") and summary rows
+("Average", "L.S.D 25% Level", "CV (%)") are skipped — a data row must
+have a real company, a variety name, and a plausible numeric yield.
+
+Rotation distinction: regional tables are corn-following-soybean (the
+default rotation); "CFC" / "Corn Following Corn" single-site tables
+(Monmouth, Urbana, DeKalb) get ``previous_crop="corn"`` and a distinct
+``-cfc-`` source_key so they never collide with the regional table.
+
+robots/ToS: no usage terms posted on the VT site (publicly-funded
+land-grant; companies pay an entry fee, which doesn't restrict published
+result reuse). Polite UA + light rate limit.

+"""Iowa Crop Performance Tests (ICPT) — cross-vendor yield trials.
+
+Iowa State University / the Iowa Crop Improvement Association run the
+**Iowa Crop Performance Tests**, an independent, third-party variety
+trial program. Because the trial is publisher-neutral, a single
+district table ranks EVERY brand head-to-head — Pioneer, DEKALB,
+Brevant, NuTech, Renk, Legacy, Epley Brothers, etc. — on identical
+plots. That makes it the highest-trust ``data_type: "trial"`` source
+in the corpus: unlike the vendor plot reports (Golden Harvest, LG,
+AgriGold, ProHarvest), no seed company controls the entry list or the
+agronomy, so there's no home-brand bias.
+
+Site shape (ASP.NET, server-rendered GridView tables — requests +
+BeautifulSoup, no JS / headless browser needed):
+
+  Corn:    https://www.croptesting.iastate.edu/corn/CornDistrict2.aspx
+  Soybean: https://www.croptesting.iastate.edu/Soybean/SoybeanDistrict2.aspx
+
+``...District2.aspx`` is the ONLY live district URL — the district
+(North / Central / South) is chosen *on that same page* via a
+``radLstDistrict`` radio (1/2/3) ASP.NET **postback**, NOT a separate
+URL (CornDistrict1/3.aspx 302-redirect away). Likewise the year
+(``cmbYear`` dropdown, 2025→2014) and the maturity season
+(``radListSeason``: 1=Early, 2=Full) are postbacks — there are no
+stable GET URLs for them. So we GET the page once to harvest the
+ASP.NET hidden fields (``__VIEWSTATE`` / ``__VIEWSTATEGENERATOR`` /
+``__VIEWSTATEENCRYPTED``), then POST the form with the desired
+year/district/season + ``btnFilter=Filter`` to drive the view.
+``CornDistrict.aspx`` (no number) is the 2013-and-older legacy page —
+out of scope.
+
+A district table is a multi-site aggregate: the GridView carries the
+district-wide Yield plus a West/East sub-region split (Wyld/Eyld) and a
+per-site yield column for each cooperator location in the district.
+That makes **one district × season × year table the natural document
+granularity** — one sidecar per ``(crop, year, district, season)``.
+
+GridView column → field map:
+  corn:    Company | Entry | RM | Herb Tech | Trait Package |
+           Yield | Yldp | Moist | Wyld | Eyld | <site> ...
+  soybean: Company | Entry | MG | Herb Tech |
+           Yield | WestYield | EastYield | <site> ...
+  Company       -> result.brand   (the seed COMPANY — critical)
+  Entry         -> result.product (variety / hybrid code)
+  Herb Tech +
+    Trait Package -> result.traits
+  everything else (RM/MG, Yield, Yldp, Moist, Wyld/Eyld, per-site)
+                  -> result.metrics  ("Yield" kept verbatim as the
+                     primary key the chunker's top-N picker reads)
+Rows are pre-sorted by Yield DESC on the page; we re-sort defensively
+and assign rank ourselves (the table has no rank column).
+
+We emit the SAME sidecar shape as ``agrigold_plot_reports`` /
+``lg_plot_reports`` / ``gh_plot_reports`` / ``proharvest_plots``
+(``results: [{rank, brand, product, traits, metrics}]``). The trial
+chunker's source dispatch doesn't list ``iowa_icpt_trials`` explicitly,
+so it FALLS THROUGH to the shared ``_render_gh_plot_chunk`` renderer —
+no ``rag/chunk.py`` edit required.
+
+Output:
+  corpus/iowa_icpt_trials/<source_key>.md      LLM-visible body
+  corpus/iowa_icpt_trials/<source_key>.json    sidecar metadata
+
+source_key: ``icpt-<crop>-<year>-<district>[-<season>]``
+  e.g. ``icpt-corn-2025-north-early``, ``icpt-soybeans-2024-south-full``.
+
+Scope: 2024 + 2025 baseline. ``--include-old`` walks 2014–2023.

+"""Ohio Corn & Soybean Performance Test (OCPT/OSPT) — independent,
+cross-vendor yield trials (data_type=trial).
+
+Source: ``ohiocroptest.cfaes.osu.edu`` — The Ohio State University /
+CFAES extension publishes the annual Ohio Corn Performance Test and
+Ohio Soybean Performance Trials as full-report PDFs with a real text
+layer. These are *third-party* university trials: every brand that
+pays the entry fee is evaluated head-to-head at the SAME sites, so a
+single report ranks CHANNEL, DEKALB, NK, Golden Harvest, LG Seeds,
+Augusta, Ebberts, Seed Consultants, etc. against each other — the
+highest-value class of trial data because no vendor controls it.
+
+This is the FOURTH ``data_type: "trial"`` source family after the
+vendor plot reports (gh / lg / agrigold / proharvest). Unlike those —
+which are ONE plot per report — the OCPT report is ONE PDF carrying a
+dozen multi-site tables, each table laying out several SITES as
+side-by-side column groups (Hebron | Washington CH | South Charleston
+| Covington | Summary). We split each report into ONE sidecar per
+SITE (and one per regional Summary), so the corpus's per-site shape
+matches the vendor plot reports and the trial chunker's shared
+``_render_gh_plot_chunk`` renderer handles it with NO chunk.py edit
+(we emit ``results: [{rank, brand, product, traits, metrics}]`` with a
+canonical ``"Yield"`` metric key).
+
+PDF layout (corn, e.g. CountryJournal2025.pdf):
+  Table 1E/1L/4E/4L/7E/7L : single-year per-site tables. A site-name
+    line names the column groups; each hybrid row carries 5 numbers
+    (Yield, Harv.Mst, Stk.Ldg, Final Std, Emergence) PER site, then a
+    single trailing TW (test weight, summary-level). These are the
+    gold per-site data — we emit one sidecar per real site (+ Summary).
+  Table 2/3/5/6/8/9 : multi-year / combined regional summaries — same
+    column-group structure (year/region groups). We emit these as
+    region-level summary sidecars (the Summary group of the matching
+    single-year table already covers the site mean, so these add the
+    2-yr / 3-yr / statewide aggregates).
+  Table 10 : hybrid -> technology-traits lookup (RR,CB,TRE,...). Parsed
+    into a traits map and joined onto every result's ``traits`` field.
+
+PDF layout (soybeans, e.g. 2025OCJwithproteinandoil.pdf): a different
+column order — ``Variety | Brand | Type | Seed Treatment | RM | <per-
+site yields> | Mean``. Region (North/Central/South) x maturity
+(Early/Late) tables, with site codes (N1/N2, C1/C2, S1/S2) defined in
+a Site-Descriptions table (Table 1). We emit one sidecar per region x
+maturity, keyed by the region (the soy report does not break per-site
+yields into separate ranked tables the way corn does — the per-site
+columns are within the regional table, so a region sidecar carries the
+full ranked field with each site's yield in the metrics).
+
+SANITY GATE: every parsed row must have a real (non-numeric, len>1)
