docker: production image + Gitea Actions for monthly refresh

Dockerfile: self-contained image with corpus + Chroma + BM25 baked
in. Drawbar's compose pulls + runs without volume mounts. Built from
sources.json (labels schema), PRODUCT_NAME=crop_chem by default,
HYBRID_SEARCH=true (always-on for production quality). RERANK_URL +
OLLAMA_URL get set at compose time.

.gitea/workflows/refresh.yml: monthly cron (1st @ 06:00 UTC) does
full scrape → reindex → image push. Scrapes Bayer (~30 min) +
EPA PPLS row-crop filtered (~7h). Skips reindex+push if no corpus
diff. Tags pushed: :latest, :<sha12>, :corpus-<YYYY.MM.DD>.

.gitea/workflows/image-only.yml: on-demand or auto on code-only
pushes to main (paths: docs_mcp/, rag/, scrape/, requirements.txt,
Dockerfile, sources.json). Reindexes from committed corpus, builds
image, pushes. ~10 min vs ~9h full refresh.

.gitignore: corpus/ now COMMITTED (4,159 labels, 265 MB of .md +
sidecars). Lets image-only.yml rebuild indexes without re-scraping.
chroma/ + bm25/ still gitignored (regenerable binary indexes).

.dockerignore: drops venv, eval results, PLAN/README/CLAUDE.md,
deploy/, .git/ — keeps the image lean. corpus + chroma + bm25
explicitly NOT in dockerignore (those go INTO the image).

+Should you wish to add/retain a reference to the company’s website on your label, then please be 
+aware that the website becomes labeling under the Federal Insecticide Fungicide and Rodenticide 
+Act and is subject to review by the Agency. If the website is false or misleading, the product 
+would be misbranded and unlawful to sell or distribute under FIFRA section 12(a)(1)(E). 40

+Therefore, should the Agency find or if it is brought to our attention that a website contains false 
+or misleading statements or claims substantially differing from the EPA approved registration, 
+the website will be referred to the EPA’s Office of Enforcement and Compliance.
+A copy of your label stamped “Accepted” is enclosed. Products shipped after 12 months from the 
+date of this amendment must bear the new revised label. Your release for shipment of the 
+product bearing the amended label constitutes acceptance of these conditions. If these conditions

+Difenoconazole belongs to the triazole class of chemistry and is a demethylation 
+inhibitor of sterol biosynthesis (DMI) which disrupts membrane synthesis of the fungal 
+cell. Mefenoxam belongs to the phenylamide class of chemistry which interferes with 
+fungal RNA synthesis.
+Dividend XL is a systemic seed dressing that controls or suppresses certain seed- 
+borne. soil-borne, and fall foliar diseases of wheat. It is a mixture of Dividend and Apron 
+XL® LS. Apron XL LS provides Pythium damping-off activity and Dividend provides 
+activity on the remaining diseases claimed on this label. An EPA-approved coloring 
+agent, Pigment Red 48 has been added to the formulation.

+For resistance management, please note that Dividend XL contains Group 
+3/difenoconazole and Group 4/ mefenoxam fungicides. Any fungal population may 
+contain individuals naturally resistant to Dividend XL and other Group 3 or Group 4 
+fungicides. A gradual or total loss of pest control may occur over time if these fungicides 
+are used repeatedly in the same fields. Appropriate resistance-management strategies 
+should be followed.
+To delay fungicide resistance, take one or more of the following steps:
+• Rotate the use of Dividend XL or other Group 3 or Group 4 fungicides within a 
+growing season sequence with different groups that control the same pathogens.
+• Use tank mixtures with fungicide from a different group that are equally effective on 
+the target pest when such use is permitted. Use at least the minimum application 
+rate as labeled by the manufacturer.
+• Adopt an integrated disease management program for fungicide use that includes 
+scouting, uses historical information related to pesticide use. and crop rotation, and 
+which considers host plant resistance, impact of environmental conditions on 
+disease development, disease thresholds, as well as cultural, biological and other 
+chemical control practices.
+• Where possible, make use of predictive disease models to effectively time fungicide 
+applications. Note that using predictive models alone is not sufficient to manage 
+resistance.
