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).

+DISPOSAL 
+PESTICIDE DISPOSAL: Wastes resulting from the use of this product may be 
+disposed of on site or at an approved waste dispos~1 facility. . 
+CONTAINER DISPOSAL: Plastic containers-Triple rinse (or equivalent). Then offer 
+for recycling or reconditioning, or puncture and dispose of in a sanitary landfill, or 
+incineration, or if allowed by state and local authorities, by burning. If burned, stay 
+out of smoke. 
+GENERAL INFORMATION 
+Do not combine with emulsifiable liquids unless previous use of the mixture has 
+proved physically compatible and safe to plants. Do not apply when shade 
+temperatures exceed or are likely to exc~ed 90°F. (Cotton is not sensitive to sulfur 
+at high temperatures.) Do not use sulfur with oil or within 30 days of an oil spray 
+(for citrus 60 days). NOTE: Sulfur will cause severe fruit and leaf injury to sulfur­
+sensitive crops. Do not apply or allow to drift to apricots, cranberries, cucurbits 
+(cantaloupes, cucumbers, melons, squash), filberts, d' Anjou and Comice pears, 
+spinach, tung trees, walnuts or other sensitive plants. Sulfur may burn foliage and 
+fruit during periods of high temperatures and under certain climatic conditions. 
+Before using, stir until smooth! Wash recommended amount through screen into 
+partially filled spray tank or premix in a small amount of water before pouring into 
+tank. Do not use a screen finer than 50 mesh in entire system. Keep agitator 
+running during filling and spraying operation. Do not allow mixture to .stand. Failure 
+to maintain agitation will cause sulfur to settle and necessitate manual removal of 
+the deposit. SULFUR 6L has strong adhesive properties_that will act as a sticker and 
+deposit builder for other spray materials. Applications made within 30 days of 
+harvest may result in excessive spray residue on fruit when picked. 
+APPLICATION AND CALIBRATION TECHNIQUES FOR SPRINKLER IRRIGATION 
+Apply this product only through the following types of irrigation systems. Do not 
+apply this product through any other type of irrigation system. Crop injury, lack of 
+effectiveness, or illegal pesticide residues in the crop can result from nonuniform 
+distribution of treated water. If you have questions about calibration, you should 
+contact State Experiment Station specialist, equipment manufacturers·, or other
+
+) 
+) 
+experts. Do not connect an irrgation system (including areenhouse systems) used 
+for pesticide application to a public water system unless the pesticide label­
+prescribed safety devices for public water systems are in place. A person 
+knowledaeable of the chemigation system and responsible for its operation, or under 
+the supervision of the responsible person, shall shut the system down' and make 
+necessary adjustments should the need arise. 
+A. Center Pivot, Traveler, Big Gun, Motorized Lateral Move, End Tow, and Side 
+(Wheel) Roll Irrigation Equipment: Operate system and injection equipment at normal 
+pressures recommended by the manufacturer of injection equipment used. Fill tank 
+of injection equipment with water. Operate system for one complete circle for 
+center pivot or one complete run for the other recpmmended equipment, measuring 
+time required amount of water injected. and acreage contained in circle or run. Mix 
+recommended amount of SULFUR 6L for acreage to be covered into same amount of 
+water used during calibration and inject into system continuously for one revolution 
+or run, but continue to operate irrigation system until SULFUR 6L has been cleared 
+from last sprinkler head. Spray mixture in the chemical supply tank must be 
+aggitated at all times, otherwise settling, ~nd uneven application may occur. 
+B. Solid Set and Hand Move Irrigation Equipment: Determine acreage covered by 
+sprinkler. Fill tank of injection equipment with water and adjust flow to use contents 
+over a thirty to forty·five minute period. Mix desired amount of SULFUR 6L for 
+acreage to be covered into quantity of water used during calibration and operate 
+entire system at normal pressures recommended by the manufacturer of injection 
+equipment used for amount of time established during calibration. Provide constant 
+mechanical agitation in the mix tank to insure that SULFUR 6L will remain in 
+suspension during the injection cycle. SULFUR 6L can be injected at the beginning 
+or end of the irrigation cycle or as a separate application. Stop injection equipment 
+after treatment is completed and continue to operate irrigation system until SULFUR 
+6L has been cleared from last sprinkler head. 
+, SAFETY DEVICES 
+(1) The systems designated above must contain a functional check valve, vacuum 
+relief valve, and low pressure drain appropriately located on the irrigation pipeline to ' 
+prevent water source contamination from backflow. (2) All pesticide injection 
+pipelines must contain a functional, automatic, quick-closing check valve to prevent 
+the flow of fluid back toward the injection pump. (3) The pesticide injection pipeline 
+must also contain a functional, normally closed, solenoid·operated valve located on 
+the intake side of the injection pump and connected to the system interlock to 
+prevent fluid from being withdrawn from the supply tank. when the irrigation system 
+is either automatically or manually shut down. (4) The system must contain 
+functional interlocking controls to automatically shut off the pesticide injection pump 
+when the water pump motor stops. 
+5. The irrigation line or water pump must include a functional pressure switch which 
+will stop the water pump motor when the water pressure decreases to the point
+
+. . 
+) 
+0) 
+. where pesticide distribution is adversely affected. (6) Systems must use a metering 
+pump, such as a positive displacement injection pump (e.a., diaphragm pump) 
+effectively designed and constructed of materials that are compatible with pesticides 
+and capable of being fitted with a system interlock. (7) Dc not apply when wind 
+speed favors drift beyond the area intended for treatment. 
+SYSTEMS CONNECTED TO PUBLIC WATER SOURCES 
+Public water system means a system for the provision to the public of piped water 
+for human consumption if such system has at least 15 service connections or 
+regularly serves an average of at least 25 individuals daily at least 60 days out of 
+the year. 
+>" 
+Chemigation systems connected to public water systems must contain a functional, 
+reduced-pressure zone, back flow presenter (RPZ) or the functional equivalent in the 
+water supply line upstream from the point of pesticide introduction. As an option to 
+the RPZ, the water from the public water system should be discarded into a reservoir 
+tank prior to pesticide introduction. There shall be a complete physical break (air 
+gap) between the outlet end of the fill pipe and the top or overflow rim of the 
+. reservoir tank of at least twice the inside diameter of the fill pipe. The system must 
+contain functional interlocking controls to automatically shut off the pesticide 
+injection pump when the water pump motor stops, or in cases where there is no 
+water pump, when the water pressure decreases to the point where pesticide 
+distribution is adversely affected. 
+For additional instructions on safety precautions, refer to statements (2). (3), (4), 
+(6), and (7) in the section on SAFETY DEVICES. 
+FIELD CROPS 
+APPLICATION INFORMATION: 
+All dosage rates are given as pints of SULFUR 6L per acre of crop, unless otherwise 
+specified. SULFUR 6L may be applied by ground equipment, aircraft, or through 
+sprinkler irrigation equipment it is essential that 'SULFUR 6L be applied in sufficient 
+water to provide adequate coverage of the crop being treated. 
+Unless otherwise specified, use the high dosage rate if conditions for disease 
+pressure are great; use the low rate if disease is light or moderate. 
+Applications on sulfur-sensitive crops should be made when lower temperatures are 
+expected.
