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).

+HYBREX 2LC is a chemical hybridizing agent which can completely suppress 
+pollen development in wheat. This property makes it possible to use HYBREX to 
+produce hybrid wheat. HYBREX is an effective chemical hybridizing agent in a 
+broad spectrum of hard red, soft red and white winter wheat as well as hard 
+red spring wheat cultivars. 
+HYBREX 2LC chemical hybridizing agent is formulated as a liquid concentrate 
+contai~iQg 2 pounds of active ingredient per gallon of product. The use of 
+TRITONlR} AG-9B or comparable 80% active nonionic surfactant, cleared for 
+application on wheat, is essential. The surfactant should be used at a rate 
+of 1 to"2 quarts per 100 gallons of spray mixture. Thorough spray coverage of 
+wheat foliage is essential. The use of a nonionic surfactant aids spray 
+coverage and wetting of foliage and may improve uptake. For the dryer western 
+wheat belt areas the addition of 2 to 4 quarts of nonionic surfactant per 100 
+gallons of spray mixture is required. 
+Mixing 
+Apply HYBREX 2LC chemical hybridizing agent at a rate of 2 to 10 pints (0.5 to 
+2.5 lb. active ingredient) per acre. FOR OPTIMUM MALE STERILITY CONSULT YOUR 
+ROHM AND HAAS SEEDS INC. TECHNICAL REPRESENTATIVE FOR SPECIFIC USE RATES FOR 
+EACH INDIVIDUAL FEMALE PARENT AT THE RECOMMENDED GROWTH STAGE OF DEVELOPMENT. 
+Fill the spray tank about two-thirds full with water. Add the required amount 
+of HYBREX 2LC chemical hybridizing agent and Tk,rON AG-9B, mix thoroughly and 
+continue filling the spray tank. Maintain sufficient agitation during wixing 
+and spraying to insure a uniform spray mixture. 
+Application 
+Apply HYBREX 2LC chemical hybridizing agent to wheat with ground equipment 
+only. Use low pressure, low drift flat fan spray nozzles. A shield should be 
+mounted on each end of the spray boom to prevent direct spraying of outer rows 
+of male parent strips. Apply HYBREX 2LC only to the female parent which is 
+planted in alternating strips between the male parent strips. Calibrate spray 
+equipment to deliver 20 to 50 gallons of spray mixture per acre. A spray 
+pressure of 15-30 psi at the nozzle tip is recommended when using low 
+pressure, low drift flat fan spray nozzles. Adjust the height of the boom 
+above the wheat to give complete coverage of foliage. The high gallonage will 
+promote necessary coverage of foliage and low pressure will reduce drift onto the male parent strips. For further information on optimum spray pressures 
+for specific nozzles refer to manufacturer charts for recommendations.

+Apply HYBREX 2lC chemical hybridizing agent between the initiation of jOinting ..•. 
+and flag leaf tip emergence stages I>f growth. Do not apply HYBREX 2LC 'later ..... . 
+than 7r days before harvest. The rate at which plants reach the prefer:r:~d •• ' •. 
+growth is dependent upon the factors such as variety, temperature and .: 
+available soil moisture. Consequently, it is necessary to pay close attention 
+to development stages after the wheat enters its early spring vigorous growth 
+phase. For best results consult your Rohm and Haas Seeds Inc. technical 
+representative for specific use rates for each individual female parent at 
+different growth stages. 
+Extreme or changing environmental conditions at spraying time should be 
+avoided if possible. For best results, delay spraying for a day or more 
+following a freeze, significant rainfall or other drastic weather changes. If 
+waiting is likely to result in abandoning a field, then consult your Rohm and 
+Haas Seeds Inc. technical representative for specific use rates for each 
+individual parent at different soil moisture levels. 
+Use Restrictions 
+Do not plant subsequent crops, other than wheat or corn in treated areas 
+within 12 months of the last application of HYBREX 2LC c~emical 
+hybridizing agent. Corn may be planted 60 days after the last application. 
+Do not yraze treated crop or use for forage or fodder.
