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).

+gets inside. Then wash thoroughly and put on clean 
+clothing. 
+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 
+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 when weather conditions favor drift from target area. Spray 
+equipment used in applying this product should be thoroughly 
+deaned before using for any other purpose. Use repeated flushing 
+with soap and warm water or suitable chemical cleaner. It is best to 
+use a separate sprayer for application of insecticides and fungicides. 
+Do not contaminate water by cleaning of equipment or disposal of 
+washwaters. This product will kill or seriously injure many desirable 
+forms of vegetation. Do not apply directly to flowers, fruits, 
+vegetables, grapes, omamentals, cotton or other desirable plants. Do
+
+not use when there is hazard from drifting mists. (Coarse sprays are 
+less likely to drift.) Vapors from this product may injure susceptible 
+plants in the immediate vicinity. Avoid contamination of water used 
+for domestic purposes and irrigation purposes. Excessive amounts of 
+this product in the soil may temporarily inhibit 
+seed germination and plant growth. 
+This product is toxic to aquatic invertebrates. Drift or runoff may 
+adversely affect aquatic invertebrates and nontarget plants. Do not 
+apply directly to water except as specified on this label. Do not 
+contaminate water when disposing of equipment washwaters. 
+GROUNDWATER CONTAMINATION 
+Most cases of groundwater contamination involving phenoxy 
+herbicides such as 2,4-0 have been associated with mixing/loading 
+and disposal sites. Caution should be exercised when handling 
+2,4-0 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 mixing/loading equipment on an impervious pad to 
+contain spills will help prevent groundwater contamination. 
+CHEMIGATION PROHIBITION 
+Do not apply this product through any type of irrigation system. 
+DIRECTIONS FOR USE 
+It is a violation of Federal law to use this product in a manner 
+inconsistent with its labeling. 
+Do not apply this product in a way that will contact workers or other 
+persons, either directly or through drift. Only protected handlers may 
+be in the area during application. For any requirements specific to 
+your State or Tribe, consult the agency responsible for pesticide 
+regulation. 
+AGRICULTURAL USE REQUIREMENTS 
+Use this product only 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 assistance. 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 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 
+Shoes plus socks 
+Protective eyewear 
+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. 
+For Turf Sites (excluding sod farms): Do not allow people (other than 
+applicator) or pets on treatment area during application. Do not enter 
+treatment areas until dust has settled. 
+STORAGE AND DISPOSAL 
+PROHIBITIONS: Do not contaminate water, food, or feed by storage 
+or disposal. Do not store under conditions which might adversely 
+affect the container or its ability to function properly. 
+STORAGE: Do not store below temperature of 00 F. If frozen, warm 
+to 400 F and redissolve before using by rolling or shaking container.

+closed when not in use. Reduce stacking height where local 
+conditions can affect package strength. Personnel should use 
+clothing and equipment consistent with good pesticide handling. 
+PESTICIDE DISPOSAL: Pesticide wastes are toxic. Improper 
+disposal of excess pesticide, spray mixture, 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: Completely empty bag into application 
+equipment. Then dispose of empty bag in a sanitary landfill or by 
+incineration, or, if allowed by state and local authorities, by burning. 
+If burned, stay out of smoke. 
+This product can reach groundwater from improper handling. To 
+minimize groundwater contamination from spills during loading, and 
+cleaning of equipment, take the following steps:

+washwater on the ground; spray or drain over a large area away from 
+wells and other water sources. 
+GENERAL INFORMATION 
+Weed Rhap® Low Volatile Granular D is formulated by 
+impregnating selected mineral granules with low volatile 2,4-0 ester, 
+to minimize drift. The 24/48 mesh size is recommended for the 
+control of certain weeds which infest turf grass and crops such as 
+corn, strawberries, and cranberries. 
+Avoid application to susceptible plants, because this product may 
+injure plants such as colton, soybeans, tomatoes, beans, fruit trees, 
+and ornamentals. DO NOT allow particles or dust to drift onto 
+desirable crops or plants. 
+Although this product contains a low volatile ester, it should be used 
+with caution where spreading vapors can damage nearby susceptible 
+plants.
+
+It is best to use separate equipment for applying 2,4-D granules. 
+Should the same equipment be used for applying other materials, 
+however, clean it thoroughly before such use to remove all traces of 
+2,4-D particles or dust. 
+APPLICATION INSTRUCTIONS 
+ORNAMENTAL TURF such as lawns, golf courses, cemeteries, and 
+parkways: To control wild onion and broadleaved weeds such as 
+dandelion, plantain, ivy, bitterweed, and dogfennel, apply 10 to 15 
+Ibs. of granules per acre in early spring when shoots are young and 
+actively growing, using a mechanical spreader. Repeat application in 
+one month to control skipped spots. Weeds over 6 inches tall are 
+sometimes resistant and should be sprayed with Weed Rhap® A-4D 
+or Weed Rhap® Low Volatile 4D. 
+NOTES FOR ALL TURF SITES: (excluding sod farms): 
+The maximum number of broadcast applications per treatment site is 
+2 per year. 
+DO NOT USE on bentgrass, St. Augustine grass, dichondra, 
+carpetgrass, or newly plugged or seeded turf. 
+IN CORN: For pre-emergence application to aid control of annual 
+grasses such as large and small foxtail, crabgrass, and 
+bamyardgrass; and broadleaved weeds such as smartweed, 
+sunflower, wild mustard, cocklebur, bindweed, dandelion, and 
+momingglory, apply as follows: With a granule applicator designed to 
+apply a band over the planted row, apply 3 to 3-1/4Ibs. per acre in a 
+band 14 inches wide when rows are 42 inches apart. If the planting 
+varies from this standard band width, or row separation, the granules 
+should be applied proportionally. Be sure the granules are allowed to 
+stay on top of the soil, preferably, they should be applied behind the 
+packer wheel at planting time. Be sure the corn is planted 2-1/2 to 3 
+inches deep, as damage may occur to shallow planted com. DO 
+NOT apply on sandy soil. (For Com Belt Only). 
+IN STRAWBERRIES: For pre-emergent application to control weeds 
+such as crabgrass, foxtail, bamyardgrass or wintergrass, horseweed, 
+bullnettle, carelessweed, morningglory, dock, smartweed, 
+jimsonweed, and dandelion: Apply at the rate of 121bs. per acre over 
+the planted area. Application should be made broadcast using a 
+spreader-seeder previously adjusted to deliver 12 Ibs. per acre. 
+Application should be made only in the dormant season (after first fall 
+frost or before new leafing in spring). 
+IN CRANBERRIES: For pre-emergent application to control annual 
+broadleaved weeds in bearing cranberry marshes, apply at a rate of 
+10 to 20 Ibs. per acre (2 to 4lbs. 2,4-D equivalent per acre).­
+Application should be made broadcast in the spring after removal of 
+the winter flood from the dormant vines. Weeds controlled are 
+common ragweed, sticktight, teathumb, smartweed, Northem Saint 
+Johnswort, and common species of annual smartweed. Careful 
+distribution of the granules is necessary if adequate control is to be 
+obtained. Granules may also be distributed on ice over plants prior to 
+spring thaw (for Wisconsin area).
