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).

+STORAGE AND DISPOSAL 
+Do not contaminate water, food or feed by storage and disposal or by cleaning of equipment. Open dumping is prohibited. 
+PESTICIDE STORAGE 
+Store in a cool, dry, secure, location. Do not store in direct hot sunlight. Keep container closed when not in use. 
+CONTAINER DISPOSAL 
+Rigid, Non-refillable containers small enough to shake (I.e., with capacities equal to or less than 5 gallons). 
+Non-refillable container. Do not reuse or refill this container. Offer for recycling, if available. Triple rinse or pressure rinse container (or 
+equivalent) promptly after emptying. 
+Triple rinse as follows: Empty the remaining contents into application equipment or a mix tank and drain for 10 seconds after the flow 
+begins to drip. Fill the container Y<I full with water and recap. Shake for 10 seconds. Pour rinsate into application equipment or a mix 
+tank or store rinsate for later use or disposal. Drain for 10 seconds after the flow begins to drip. Repeat this procedure two more times. 
+Pressure rinse as follows: Empty the remaining contents into application equipment or a mix tank and continue to drain for 10 seconds 
+after the flow begins to drip. Hold container upside down over application equipment or mix tank or collect rinsate for later use or 
+disposal. Insert pressure rinsing nozzle in the side of the container, and rinse at about 40 PSI for at least 30 seconds. Drain for 10 
+seconds after the flow begins to drip. 
+Once container is rinsed, offer for recycling if available, 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.

+Pressure rinsing the container before final disposal is the responsibility of the person disposing of the container. To pressure rinse the 
+container before final disposal, empty the remaining contents from the IBC into application equipment or mix tank. Raise the bottom of 
+the IBC by 1.5 inches on the side which is opposite of the bottom discharge valve to promote more complete product removal. 
+Completely remove the top lid of the IBC. Use water pressurized to at least 40 PSI to rinse all interior portions. Continuously pump or 
+drain rinsate into application equipment or rinsate collection system while pressure rinsing. Continue pressure rinsing for 2 minutes or 
+until rinsate becomes clear. Replace the lid and close bottom valve.

+Triple rinsing the container before final disposal is the responsibility of the person disposing of the container. To triple rinse the 
+container before final disposal, empty the remaining contents from this container into application equipment or mix tank. Fill the 
+container at least 10 percent full with water. Agitate vigorously or recirculate water with the pump for 2 minutes. Rinse all interior 
+surfaces. Pour or pump rinsate into application equipment or rinsate collection system. Repeat this procedure two more times. 
+Once container is rinsed, offer for recycling if available or puncture and dispose of in a sanitary landfill, or by incineration. 
+Refillable Containers 
+Refillable container. Refill this container with pesticide only. Do not reuse this container for any 
+other purpose. Do not remove tamper evident cables or one way valves or clean the container if the container is equipped with one way

+LABELING OF TREATED SEED 
+Seed that has been treated with this product that is then packaged or bagged for future use must contain the following 
+labeling on the outside of the seed package or bag. 
+• This seed has been treated with carboxin and pentachloronitrobenzene (PCNB). 
+• Do not use for feed, food or oil purposes. 
+• Store away from feeds and foodstuffs. 
+• When opening this bag or loading/pouring the treated seed, wear long-sleeved shirt, long pants, shoes, socks, 
+and chemical resistant gloves. 
+• Treated seed exposed on soil surface may be hazardous to birds. Cover or collect spilled seeds. 
+• This product may have effects on federally listed threatened or endangered species or their critical habitat in 
+some counties. It is a violation of federal law to kill, harm or harass listed animal species without authorization. To 
+limit the potential for such impacts when using this product, consult and follow the instructions provided in the 
+EPA Endangered Species Bulletin for the County or Parish in which you are applying the seed. To determine 
+whether your County or Parish has a Bulletin consult http://www.epa.gov/espp before each season's use of this 
+product. 
+• After the seeds have been planted, do not enter or allow worker entry into treated areas during the restricted­
+entry interval (REI) of 12 hours. Exception: Once the seeds are planted in soil or other planting media, the Worker 
+Protection Standard allows workers to enter the treated area without restriction if there will be no worker contact 
+with the soil subsurface. 
+• Do not graze or feed livestock on treated areas of wheat, barley, or oats for six weeks after planting. Do not graze 
+or feed livestock on forage or hay grown from treated cotton or soybean seed. 
+VITAVAX-PCNB Flowable Fungicide combines the systemic action of carboxin with the surface action of PCNB to 
+control various seed and seedling diseases. It is particularly effective against Rhizoctonia so/ani. 
+COMPATIBILITY 
+VIT AVAX-PCNB Flowable FungiCide should not be tank mixed with any pesticide unless adequate physical and 
+compatibility and phytotoxiCity tests have been completed and proved to be satisfactory. 
+USE RESTRICTIONS 
+Do not use treated seed for food, feed or oil purposes. Do not graze or feed livestock on treated areas of wheat, barley, or 
+oats for six weeks after planting. Do not graze or feed livestock on forage or hay grown from treated cotton or soybean 
+seed. Care must be exercised in the handling of treated seed. 
+Since this product does not contain a dye, all seed treated with this product must be colored with an EPA-a{){)wved dye 
+(e.g., 40 CFR 180.1001) which imparts an unnatural color to the seed to help prevent the inadvertent use at troated seed 
+as food for man or feed for animals. , ,
