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).

+pesticide gets inside. Then wash thoroughly and put on dean dething. Remove PPE immediately after handling this product. 
+Wash the outside of gloves before removing. As soon as possible, wash thoroughly and change into clean clothing. 
+ENVIRONMENTAL HAZARDS 
+Drift or run-off may adversely affect nontarget plants. For terrestrial uses, do not apply directly to water, or to areas where surface water 
+is present or to intertidal areas below the mean high water mark. Do not contaminate water when disposing of equipment washwaters 
+or rinsate. When cleaning equipment, do not pour washwater on the ground; spray or drain over a large area away from wells and other 
+water sources. Do not apply when weather conditions favor drift from target areas. 
+Most cases of groundwater contamination involving phenoxy herbicides such as MCPA have been associated with mixing/loading and 
+disposal sites. Caution should be exercised when handling MCPA pesticides at such sites to prevent contamination of groundwater 
+supplies. Use of closed systems for mixing or transferring this pesticide will reduce the probability of spills. Placement of the 
+mixinglloading equipment on an impervious pad to contain spills will help prevent groundwater contamination.

+GENERAL INFORMATION 
+USE PRECAUTIONS: Under no circumstances should MCPA AMINE HERBICIDE be used in the vicinity of vegetables, flowers, 
+grapes, tomatoes, cotton. beans and other legumes, etc. or other suscepUble crops as severe damage may result. Extreme care must 
+be exercised to prevent drifting of this material. Do not apply on windy days. Coarse sprays are less likely to drift. Avoid use of small 
+diameter spray nozzles. Do not use around the home, recreation areas, or similar sites. Equipment used to apply MCPA AMINE 
+should not be used to apply other agricultural chemicals to susceptible crops. 
+CONTROLS THESE WEEDS 
+SUSCEPTIBLE (Most Areas): Lambsquarters (GoosefDOt), Marsh Elder, muslards (annual), puncturevine, ragweed, stinkweed, wild 
+radish, yellow rocket or wintercress, cocklebur, goats beard, field pepper grass, dragon head mint, shepherdspurse and many others. 
+LESS SUSCEPTIBLE: Buttercups, Canada thistle, dandelions, kochia, plantains, hempnettie, stinging nettle, sow thistle, vetch, white 
+top and hoary cress, Russian pigweed, sunflower, pigweed, purslane and many others. 
+CROP SPRAYING 
+Obtain uniform spray coverage for best results. Generally, the lower recommended dosages will be satisfactory for young, succulent 
+growth of sensitive weed species. Use the higher recommended dosages INhere less sensitive species are to be controlled. Use 
+moderate spray pressure (20 psi) and enough spray volUme for good coverage, usually 5 to 20 gallons per acre by ground equipment 
+and at least 3 to 5 gal/ons per acre by air unless directed otherwise. 
+SELECTIVE SPRAYING: Wheat, Oats, Ba~ey and Rye - Apply as a water mix spray by ground sprayer or airplane. Use 1/2 to 1 pint 
+per acre for the more susceptible weeds after crop has reached the 3 to 4 leaf stage up to boot stage. Use up to 3 pints per acre for 
+less susceptible weeds after crop has tiIIered and up to early boot stage. Do not spray from boot to dough stage. 
+For small grains underseeded with legumes, see the following paragraph. 
+SMALL GRAINS, Underseeded with Alfalfa, Lespedeza, Red and White Clover: For emergency control of serious infestations of 
+mustard, yellow rocket and other susceptible broadcast weeds, apply ~ to Y2 pint in not more than 5 to 10 gallons of water per acre. 
+Make application after cereal is well tillered (4 to 8 inches tall) and before reaching boot stage. The nurse crop and weeds should 
+provide a protective canopy which, together with the use of low gallonage applied with pressure, will reduce the risk of damage to the 
+legumes. Do not apply to small grains underseeded with vetch or sweet dover, which are very susceptible. There is also some risk to 
+other legumes if only thinly protected by a canopy. Do not forage or graze meat animals or dairy cattle within 7 days of slaughter. 
+CANNING PEAS (For use in the Pacific Northwest only): Use MCPA Amine Herbicide at 1/4 to 314 pint per acre. Apply to peas after 
+the 3 node stage and before the first pea flowering. Do not apply during bloom period of crop. To control Canada thistle, use 112 to 314 
+pint per acre. Peas may be injured somewhat at the higher rate of application, but if thistle growth is heavy, control will more than 
+compensate for injury to peas. Do not feed treated vines to livestock. Do not forage or graze meat animals or dairy cattle within 7 days 
+of slaughter. 
+FLAX: Use 1/4 to 1/2 pint. Apply by ground sprayer or by airplane. Use sufficient water to give uniform and adequate coverage. Apply 
+only when weeds are up and when flax is 4 to 8 inches high and before it comes into bud. Treatment after early bud stage may result in 
+severage damage. If Canada thistle is present, it may be necessary to go as high as 3/4 pint per acre to prevent seed head production. 
+Some injury to the flax may result. Do not forage or graze meat animals or dairy cattle within 7 days of slaughter. 
+ESTABLISHED GRASSLAND AND PASTURES: Use 1 to 3 pints per acre in sufficient water (10 to 100 gallons) in airplane or ground 
+sprayer application and give thorough coverage. Use higher rate for white top, Canada thistle and other less easy·to-kill weeds; spray 
+perennials in early bud to full bloom stage and also regrowth in fall. Spray other weeds in spring or fall. Do not forage or graze meat 
+animals or dairy cattle within 7 days of slaughter. 
+GRASSES GROWN FOR SEED: Use 1 to 2 pints per acre in sufficient water to give adequate coverage. Use higher rate where weed 
+stands are heavy. In established grasses apply in spring before head comes into boot and on seedling grass after grass has tiIIered. 
+NOTE: In weed control in grasses, repeat treatment may be needed for less susceptible weeds. White dover and other legumes may 
+be temporarily injured or killed. In some areas, bent, buffalo, carpet and St. Augustine grasses may also be injured by the treatment. 
+RANGE AND TIMBER LANDS: For control of whitebrush, use 1 X. quarts in a mixture of 1 gallon of diesel oil and sufficent ,\J:S: to 
+make 8 gallons of solUtion per acre. Apply in spring or fall under good moisture conditions, full leaf, before blossoms begin to f;-I' Do 
+not forage or graze meat animals or dairy cattle within 7 days of slaughter.

+NON-CROP SPRAYING 
+CANADA THISTLE, WHITE TOP AND MEADOW BUTTERCUP (In Non-Crop Areas such as Roadsides, Fence Rows, Rights-of­
+Way and Similar Places): For spot treatment, use V. pint in 3 to 4 gallons of water, or 3/4 gaUon per acre in 75 to 150 gallons of water. 
+depending on the weed density and height, to give coverage of the weed foliage. Spray to wet weeds thoroughly when in bud to early 
+bloom and again on faU regrowth. Do not forage or graze meat animals or dairy cattle within 7 days of slaughter. 
+Local conditions may affect the use of this chemical. Consult State Agricultural Extension or Experiment Station weed specialists for 
+specific recommendations for local weed problems and for infonnation on possible lower dosages. 
+ESTABLISHED TURFGRASS AREAS; Such as: Golf Courses, Lawns, Parks, Cemeteries, and Other Turf Areas. Use 1 to 3 
+pints per acre in 10 to 120 gallons of water to give thorough coverage. Use higher rate for less susceptible weeds. On smaller areas 
+use 1 fluid ounce (4 tablespoonfuls) mixed in 1 to 3 gallons of water and apply uniformly over 1.000 square feet. Do not exceed 
+specified application dosages for any area. Avoid applying during excessively dry or hot periods unless irrigation (watering) is used 
+before treatment. For best results, do not apply if rainfall is expected within 48 hours, nor should lawns be watered for 48 hours 
+following application. For optimum results, turf should not be mowed for 1 to 2 days before and after application. Reseed no sooner 
+than 3 to 4 weeks after application of this product. Spring and fall are best times to treat. Do not use on lawns of creeping bentgrass, 
+except for spot spraying, nor on newly seeded turf until the grass has become well established, usually after the third or fourth mowing.
