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).

+or to intertidal areas below the mean high water mark except as noted on appropriate labels. Drift and runoff may be hazardous to 
+aquatic organisms in water adjacent to treated areas. Do not contaminate water when disposing of equipment wash waters or rinsate. 
+This chemical has properties and characteristics associated with chemicals detected in groundwater. The use of this chemical in areas 
+where soils are permeable, particularly where the water table is shallow,. may result in groundwater contamination. Application around 
+a cistern or well may result in contamination of drinking water or groundwater.

+pesticide regulation. 
+Do not apply at rates higher than recommended. Excessive amounts in the soil may temporarily stop seed germination or plant 
+growth. Do not use on light, sandy soils. If regular insecticide spreader is ·used to apply this product, be sure to clean equipment 
+thoroughly before other use. This product will injure vegetables, flowers, grapes, fruit plants, ornamentals, cotton, soybean, and other

+AGRICULTURAL USE REQUIREMENTS 
+Use this product orily in accordance with its labeling and with the Worker Protection Standard, 40 CFR part 170. This Standard 
+contains requirements for the protection of agricultural workers on farms, forests, nurseries, and greenhouses, and handlers of 
+agricultural pesticides. It contains requirements for training, decontamination, notification, and emergency assistan~e. It also 
+contains specific instructions and exceptions pertaining to the statements on this label about personal protective equipment (PPE) 
+and restricted-entry interval. The requirements in this box only apply to uses of this' product that are covered by the Worker 
+Protection Standard. 
+Do not enter or allow worker entry into treated areas during the restricted-entry interval (REI) of 12 hours. 
+PPE required for early entry to treated areas that is permitted under the Worker Protection Standard and that involves contact with 
+anything that has been treated, such as plants, soil, or water, is: coveralls, chemical-resistant gloves made of any waterproof 
+material and shoes plus socks. 
+NON-AGRICULTURAL USE REQUIREMENTS 
+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 enter or allow people (or pets) to enter the treated area until dusts have settled. 
+CROPS 
+CORN (Field): For preemergence application to aid control of annual grasses such as large and small Foxtail (Pigeon grass), 
+Crabgrass, Barnyardgrass; broadleaved weeds such as Smartweed, Sunflower, Wild mustard, Cocklebur, Bindweed, Dandelion, 
+Morningglory, Pigweed, Tarweed, Ragweed, Wild radish, Pennyworts, Plantains, Healall, Chicory, Yellow star thistle, Lambsquarters, 
+and Watergrass. 
+This product should be applied preferably at corn planting time. It may, however, also be applied just before corn emerges through 
+the soil. Plant corn at least 2 inches deep when using preemergence 2,4-0 applications. This will aid in preventing injury from leaching 
+of weed killer. With this treatment, one should not expect season-long control. It is intended to control grasses for 3 to 4 weeks so that 
+the corn seedlings can get started without competition. It has very little effect on established broadleaf weeds over 6 inches tall; and 
+none at all on grassy weeds once they have germinated. 
+Use 5 pounds of this product per acre applying to soil from time of planting up to 2 days before corn seedlings emerge. This application 
+is on a broadcast basis equivalent to 1 pound ,of actual 2,4-0 (Acid) equivalent. For band or row application approximately 14 inches 
+wide, apply 3.5 pounds of this product per acre on 40 inch rows. Limited to one preplant or preemergence application per crop cycle 
+at a maximum of 5 pounds per acre per application. 
+CRANBERRIES: For preemergence application to control annual broadleaved weeds in bearing cranberry marshes, apply at a rate 
+of 10 to '20 pounds per acre (2 to 4 pounds 2,4-0 equivalent per acre). Application should be made broadcast in the spring after 
+removal of the winter flood from the dormant vines. Limited to one dormant season application per crop cycle at a maximum of 20 
+pounds per acre per dormant season. Weeds controlled are Common Ragweed, Sticktight, Tearthumb, Smartweed, Northern Saint 
+Johnswort, and common species of Annual Smartweed. Careful distribution of granules is necessary if adequate control is to be 
+obtained. (For Wisconsin area granules may also be distributed on ice over plants prior to spring thaw.) 
+TURF 
+ORNAMENTAL TURF: (such as lawns, golf courses, cemeteries, and parkways). To control Wild onion and broadleavEid weeds such 
+as Dandelion, Plantain, Ivy Bitterweed, and Dogfennel, apply S pounds of granules per acre in early spring when shoots are young 
+and actively growing, using a mechanical spreader. Repeat application in one month or later to control skipped spots. 
+DO NOT USE on Bentgrass, St. Augustinegrass, Dichondra, Carpetgrass, or newly plugged or seeded turf. 
+The maximum rate per application is S'pounds per acre, limited to 2 applications per year. The maximum seasonal rate is 16 pounds 
+per acre, excluding spot treatments. 
+STORAGE AND DiSpoSAL 
+Do not contaminate water, food or feed by storage or disposal. 
+PESTICIDE STORAGE: Store pesticides in a secure warehouse or storage building inaccessible to children and domestic 
+animals. Avoid storing near open containers of fertilizer, seed or other pesticides. Keep container tightly sealed when not in use. 
+Reduce stacking height where local conditions can affect package strength. 
+PESTICIDE DISPOSAL: Pesticide wastes are toxic. If container is damaged or if pesticide has leaked, clean up all spilled 
+material. Improper disposal of 'excess pesticide, spray mixtures or rinsate is a violation of Federal law and may contaminate 
+groundwater. If these wastes cannot be disposed of by use according to label instructions, contact your State Pesticide or 
+Environmental Control Agency, or the Hazardous Waste representative at the nearest EPA Regional Office for guidance. 
+CONTAINER DISPOSAL: Nonrefillable container. Do not reuse or refill this container. Completely empty bag into ap!?lication 
+equipment. Offer bag for recycling, if available. Empty bag may be disposed of in a sanitary landfill or by incineration, or, if allowed 
+by State and local authorities, by burning. If burned, stay away from smoke.
