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).

+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, 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 worker entry into treated areas during the restricted-entry interval (REI) of 12 hours.

+COTTON 
+For Damping-off caused by Rhizoc/onia solani: As a row treatment use lh gallon for sandy soil and I gallon for organic 
+soils per acre in a minimum of 15 gallons of water for 13,000 linear feet ofrow based on a 40 inch spacing. Direct the 
+spray toward the seed and surrounding soil at planting time. Do not allow livestock to graze or feed on cotton foliage 
+in peNB treated fields. 
+BEANS 
+For Root and Stem Rot caused by Rhizoctonia solani: As a furrow treatment apply 2 to 3 quarts mixed in 8 to to 
+gallons of water and apply to 14,500 linear feet of bush beans or 8,340 linear feet of pole beans. Direct the spray to the 
+base of planting furrow in front of seed drop and to the covering soil at planting time. Do not directly spray bare seed 
+since delayed emergence may result. In California and Ariwna use 3 to 4 pints in 8 to 10 gallons of water and apply to 
+the same linear feet as above indicated for bush and pole beans. Direct the spray to the furrow and to the covering soil 
+at planting time. Use the lower rates for sandy and light soils. Do not apply to bare seed. 
+SNAP & DRY BEANS· 
+For White Mold caused by Sclero/inia sclerotiorum: Apply as a band row treatment in an 8 inch wide band centered on 
+the row, immediately after or at the time of planting by using 1 gallon mixed in 8 to 10 gallons of water to treat 14,500 
+linear feet of row for bush beans or 8,340 linear feet for pole beans. ·Not for use in California 
+Avoid application directly to seed since delayed emergence may occur. When Dinitro type pre-emergence herbicides are 
+used, add I gallon of this product to the final spray mix of the herbicide and apply simultaneously. lfdisease is severe 
+additional appHcations may be made at 2 to 3 week intervals using I or 2 nozzles per row and directing the spray to the 
+soil at the base of the plants. Apply at the same rate using I gallon in 8 to 10 gallons of water to treat 14,500 linear feet of 
+row. Do not apply after the first blooms appear. Do not feed treated vines to livestock. 
+GARLIC· 
+For White Rot caused by Sclerotium cepivorum: As a fUl!ow treatment use 10 gallons of this product mixed in tOO 
+gallons of water and apply at planting time 21,800 linear row feet per acre when crop row spacing is 24 inches. This rate 
+is equivalent to 58.7 oz. ofPCNB 2-E LIQUID per 1, 000 linear feet of row. Utilize an appropriate spray rig attached to 
+the planter and spray 8 to 12 inch wide bands using 2 nozzles per planting furrow. Direct the front nozzle to treat the 
+bottom of the open furrow and the seed as it is dropped from the planter and the rear nozzle to treat the soil as the seed is 
+covered. *Notfor use in California 
+PEANUTS .... 
+For Damping-offcaused by Rhizoctonia solani: As a row treatment in sandy soils use Y, gallon ofPeNB 2-E LI<:!WIDar:d 
+in organic soils use 1 gallons PCNB 2-E LIQUID per acre in a minimum of 15 gallons of water for 13,000 linea: I1:eJ, of 
+row based on a 40 inch row spacing. Direct the spray toward the seed and surrounding soil at planting time. Do n~~alJow 
+livestock to graze or feed in peNB treated fields. 
+POTATOES • 
+. " For Rhizoctonia solani as a pre-planting broadcast soil treatment use 9 to 12 Y:! gallons per acre mixed with sufficiepf .. 
+waterto total 25 gallons of finished spray. Apply to the soil surface prior to planting and thoroughly disc to a de~tp.of •• 
+4 inches by cross discing. Attach a harrow on the last discing. It is desirable to make this treatment when the soil is • 
+slightly moist. As a furrow treatment use 5 gallons mixed in 15 gallons of water per 12,400 linear feet of row. Using 
+three nozzles per row place the front '"Fan" type nozzle ahe~d of the furrow opening disc with two "Cone" type n.ules· • 
+placed above and slightly ahead of the closing discs in the rear. Select nozzles that will deliver about 1/3 of the spmy·"

+AS A SEED TREATMENT FUNGICIDE 
+For Barley, Beans, Com, Cotton, Peas, Sorghum, Soybeans, Rice, Oats, Safflower, Sugar Beets and Wheat. For 
+Control of listed Smut diseases and Damping-off caused by Rhizoctonia. 
+Seed Treatment 
+Use PCNB 2-E LIQUID with suitable liquid or slurry type seed treating equipment such as Panogen or Mist-O-Matic 
+and apply at the rates as indicated below. Seed to be used for planting should be sound, fully cured, cleaned and have 
+an excellent gennination record. Use the following seed treatment rates per 100 Ibs. of seed. 
+Important 
+The "Seed Treater" is responsible for the use of an approved seed treater dye in the discoloration of seed that is to be 
+treated and sold for further sales in Interstate commerce. The Federal Government and most States have seed laws or 
+regulations that require treated seed to be "tagged" with an appropriate caution statement such as the following and as 
+found at the bottom of this column for treated seed. Check with such Agencies before release of treated seed. 
+How to Apply 
+Apply PCNB 2-E LIQUID undiluted to the seed directly from the drum at recommended rates. If desirable add one 
+part water to five parts PCNS 2~E LIQUID. Make sure to recalibrate equipment to deliver the recommended rate of 
+PCNB 2-E LIQUID per 100 Ibs. of seed. Refer to the following chart. "Use highest rate for pathologically infected 
+seed and when conditions are known to favor the development of soil~bome diseases. ···For Cotton use the lower rate 
+for acid delinted; the higher rate for mechanically delinted. ··.·Not for use on Com, Rice or Saffiower in California.
