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).

+This product is toxic to aquatic invertebrates. Drift or runoff may adversely affect 
+aquatic invertebrates and nontarget plants. 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 apply directly to flowers,· fruits, vegetables, grapes, ornamentals, 
+cotton or other desirable plants. Do not apply when weather conditions favor drift 
+from target area. (Coarse sprays are less likely to drift.) Vapors from this product 
+may injure susceptible plants in the immediate vicinity. Clean and rinse spray 
+equipment using soap or detergent and water or suitable chemical cleaner, and rinse 
+thoroughly before reuse for other spraying. It is best to use a separate sprayer for 
+application of insecticides and fungicides. Dc not contaminate water when disposing 
+of equipment washwaters. Do not apply this product through any type of irrigation 
+system. Do not contaminate domestic or irrigation waters. Excessive amounts of this 
+product in the soil may temporarily inhibit seed germination and plant growth. 
+Most cases of groundwater contamination involving phenoxy herbicides such as 2,4-D 
+have been associated with mixing/loading and disposal sites. Caution should be 
+exercised when handling 2,4-D pesticides at such sites to prevent contamination of 
+groundwater supplies. Use of closed systems for mixing or transferring this ~esticide 
+will reduce the probability of spills. Placement of mixing/loading equipment o'n an 
+impervious pad to contain spills will help prevent groundwater contamination~·~~

+NON-AGRICULTURAL OSI!: RRQOIRBMBNTS 
+The requirements in this box apply to uses of this product that are NOT within the 
+scope of the Worker Protection Standard for agricultural pesticides (40 CFR part 170). 
+The WPS applies when this product is used to produce agricultural plants on farms, 
+forests, nurseries. or greenhouses. 
+Do not allow people (other than applicator) or pets on treatment area during 
+application. Do not enter treatment areas until spray has dried. 
+General Directions - All broadleaf plants do not respond the same. Young and actively 
+growing weeds are easier to kill and the lower dosages may be used here. For the less 
+sensitive species and under conditions where kill is more difficult, the higher dosages ( 
+should be used. -
+Use 2,4-0 L.V. 2 Ester for control of the following weeds: 
+Bitterweed, Broomweed, Croton weed, Dandelion, Docks, Dogfennel, Fanweed, Kochia, 
+Lambsquarters, Mallow, Marshelder, Mustards, Peppergrass, Pigweed, Plantains, Ragweed, 
+Shepherdspurse, Tarweed, Thistles, Vetch, Wild carrot, wild garlic, Wild morningglory, 
+Wild onion, Wild radish, many other broadleaved weeds; Alder, Buckbrush, Coastal sage, 
+Elderberry, Hazel, Sand sagebrush, Sand shinnery oak, Sumac, Willow, and certain other 
+woody perennials. 
+t • r , 
+• • Mixing Dit&~tions - When used on crops at the higher rates recommended 2,4-0 L.V. 2 Ester 
+may caus~' ~()tn.e injury to crop plants, especially if crop is growing rapidly. However, 
+where wee6s'~re a serious problem, weed control will often offset crop damage. Do not 
+overdose o~ use o~'c~~s not recommended on this label. In preparing the mixture, add 
+half the, i·~ttqired' water to the tank. Begin agitation and add 2,4-0 L. V. 2 Ester and then

+Weeds in c .. :;rr. - P03':. -Emergence: Use 3/4 pint 2,4-0 L. V. 2 Ester in the amount of water 
+necessary ,~o cover 1; acre. If weeds are sensitive, dosage can be reduced to 1h pint while 
+more resi~bant weeds may require dosage of 1 pint. Apply spray as soon as majority of 
+weeds ha~·germinated. Drop nozzles should be used after corn is 10 inches tall in order 
+to keep spray off corn leaves. Do not apply from tasseling to dough stage. Pre-Emergence 
+Applicat~cn.· Use 2 to 4 quarts 2,4-0 L.V. 2 Ester in 10 to 20 gallons water per acre. 
+Apply after planting anytime, but before corn emerges. Do not treat light sandy soils.

+Riverdale 2,4-D L. V. 2 Ester Page 5 
+Weeds in Spring Wheat and Barley - Use 1 pint 2,4-6 L.V. 2 Ester in necessary water to 
+spray one acre. Make spray application when grain is in full tiller stage (6 to 8 in. 
+tall) until the early boot stage. Injury can occur if sprays are applied to young 
+seedling or when grain is in the boot or shot blade stage. Dosages may be increased ~ 
+pint for more resistant weeds or decreased ~ pint for easy to kill weeds. 
+Weeds in Winter Wheat and Rye - Use 1 to 1-1/2 pints 2,4-D L.V. 2 Ester in necessary water 
+to spray one acre. Make application in the Spring from the fully tillered to the jointing 
+stages. 
+Weeds in Oats Not Underseeded with Legumes - Do not use over 1 pint 2,4-D L.V. 2 Ester in 
+necessary water to cover one acre. Since recommendations vary in states as to proper time 
+of application, follow local state recommendations as to timing of spray. 
+Weeds in Pasture - To control most broadleaf weeds, use 1-1/2 to 2 quarts 2,4-D L.V. 2 
+Ester in sufficient water to cover one acre. Apply when weeds are growing best. For the 
+control of wild garlic and Wild onion, increase dosages to 4 to 6 quarts per acre. Make 
+three applications in Fall-Spring-Fall or Spring-FaIl-Spring sequence. Do not apply to 
+creeping grasses or freshly seeded pastures. Most legumes are also damaged or killed. 
+Weeds in Ornamental Lawns and Turf - To control most broadleaf weeds in institutional, 
+)rnamental and residential/domestic sites, use 1-1/2 to 2 quarts 2,4-D L.V. 2 Ester in 
+dufficient water to cover one acre per application per site. Apply when weeds are 
+growing best. For the control of Wild garlic and Wild onion increase dosage to 4 quarts 
+per acre. Make two applications in Fall-Spring or Spring-Fall sequence. Do not apply to 
+creeping grasses or freshly seeded lawns. 
+Roadside and General Weed Control - Use 2 to 3 quarts 2,4-D L.V. 2 Ester in 100 gallons of 
+water. Apply as a wetting spray covering all foliage thoroughly. This application is 
+recommended along roads, rights-of-way, fence rows, and in pole yards and similar non-crop 
+areas. 
+Woody Plant Control - For 2,4-D susceptible brush like Willow, Elderberry, Sumac, apply a 
+drenching spray using 3 quarts 2,4-D L.V. 2 Ester in 50 gallons water. Wet thoroughly, 
+including foliage, bark and shoot stems down to ground level. This use should be confined 
+to non-crop areas described under directions for Roadside and General Weed Control. 
+Knapsack Applications - For spot treatment of weeds, mix one cupful 2,4-D L.V. 2 Ester in 
+3 gallons of water and wet all foliage thoroughly to runoff stage. 
+STORAGE AND DISPOSAL 
+STORAGB: Always use original container to store pesticides in a secured warehouse or

+pesticides. Do not contaminate water, food or feed by storage or disposal. 
+PESTICIDE DISPOSAL: Pesticide wastes are toxic. Improper disposal of excess 
+pesticide, spray mixtures, or rinsate is a violation of Federal law and may ~~.e 
+contaminate groundwater. If container is damaged or if pesticide has leaketl.<aOntain
