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).

+Cyanazine and atrazine are pesticides which can move (seep or travel) through 
+soil and can contaminate groundwater which may be used as drinking water. 
+Cyanazine an3 atrazine have been found in groundwater as a result of 
+agricultural use. Users are advised not to apply cyanazinc where the water 
+table (grolmdwater) is close to the surface and \..'hcrc the soils are very 
+permeab]p (i.c., we1l-drained soils such as lOaJllY snnds). Your local 
+agricultural aecncics can pt'ovide furthel." information on the type of soil in

+GENERAL INFORl!ATION 
+BLADEX/Atrazinp (2: 1) BOil Herbicide is a selective preemergence helChicid,· 
+p~1ckage mix for the control of annual grasses and broadleaved weeds in field 
+corn. The control of grasses is improved with this package mix. 
+Consult your local Agricultural Extension Agent for help in determining 
+soil type, organic matter content. and the most appropriate herbicirle rate 
+for local conditions. 
+lIhen BUIDEX/Atrazine (2:1) BOil Herbicid<! is used as directed on this 
+label. the user can only plant field corn or rotate from corn to corn or 
+sorghwn the following year.
+
+- 4 -
+As a prcemcrgence herbicide BLADEX/Atrazine (2:1) BOw is activ(> mainly 
+through the roots, and therefore its effect on weeds is dependent on adequate 
+rainfall to move the herbicide into the root zone. A ~otary hoeing or 
+shallow cultivation is recommended if a rainfall or sprinkler irrigation has 
+not occurred '.r1ithin about ten days after application of Bl.ADEX/Atrazine (2: 1) 
+80\.1. 1-1oisture should be sufficient to wet the top 1. 1/2 to 2 inches of soi 1 
+or make the soil too wet to cultivate; for most soils one-half inch of 
+moisture sufficient. Under conditions which delay weed germination, such as 
+low temperatures, lack ~f soil surface moisture, or when germination extends 
+OVer a long period. che effectiveness of the herbicide may be impaired. 
+Rotary hoeing or a shallow cultivation may be of benefit under these 
+circumstances. If the corn i::> cultivated. tillage should be shallow to 
+minimize herbicide dilution in the soil. Should the corn stand be lost due 
+to adverse weather conditions t the field can be replanted the same season to 
+corn or sorghum. 
+BLADEX/Atrazine (2:1) SOW is not effective when used preemergence on peat 
+or muck soils. Do not use BLADEX/Atrazine (2:1) 80w on sands or loamy sands 
+(soils consisting of more than 70% ~and) containing less than 1% orBanic 
+matter. BLADEX/Atrazine (2:1) SOW should be applied only once per crop 
+season. 
+Observe all cautions and limitations of labeling of all producLs used in 
+mixtures. The effectivenpss of any combinations is generally dependent on 
+weed spectrum, soil texture and soil organic matter content. 
+APPLiCATION DIRECTIONS 
+Gener~l Hixing and Spraying Directions 
+Be sure the sprayer tank, boom and nozzles have been thoroughly flush~d 
+, . ..'ith clean water, if another pesticide has been used pn:,'.'iously. 
+Sufficient jet or mechanical aeitat.ion should bp. provided during tlw 
+filling operation and during application. Fill the spray tank at least 
+one-half full of clean water and "'hile pump and agitator are running, add th(! 
+recommended .,mount of BUIDEX/Atrazine (2:1) SOW to the tank, then fill with 
+water to the desired level. (BLADEX/Atrazine (2:1) BOW Herbicide can be 
+premixed 8S a slurry before adding to the tank.) 
+Allow the pump to run several minutes before application to ensure propel 
+suspension and mixing of BLADEX/Atrazine (2: 1) SOW. If BLADEX/Atrazine (2: l) 
+BOW is allowed to stand in a spray tank or nurse tank for an extended period 
+(several hours or overnight), provide good agitation for several minutes 
+before application to ensure proper suspension and mixing.
+
+( 
+- 5 -
+Apply with flat fan (even flat fan or band application) or flooding 
+nozzle in conjunction with 50-mesh nozzle screens and in-line screens. 
+Cal"efully follow the nozzle manufacturer's recommendation for correct nozzle 
+height. positioning and spacing. Check for uniform distribution or spray 
+droplets. Apply at pressures of 20-40 psi to reduce chemical loss due to 
+fine mist drift. 
+Check nozzles, pressure, and output regularly to assure proper 
+calibration and application. 
+Apply the spray solution containing BUIDEX/Atrazine (2:1) 80w evenly to 
+the soil surface using 15-30 gallons per acre for ground application. A 
+rotary hoeing is recommended for those applications of BLADEX/Atrazine (2:1) 
+80W which are not incorporated at time of treatment or which do not receive 
+adequate rainfall or sprinkler irrigation within about 10 deys after 
+application. 
+Preemergence, Preplant or Preplant Incorporated 
+Apply BLADEX/Atrazine (2:1) 80W immediaLely before planting, at planting, 
+or after planting, but before the crop has emerged. The removal of treated 
+soil from seed row prior to or during planting operation may reduc(> the 
+effectiveness of this product in the ro~ where preplant applications are 
+used. 
+Use BlADEX/Atrazine (2.1) SOW at 1.5 to 5 pounds per acre in broadcast 
+treatments. (For band application, use proportionately less.) Adjust the 
+rate of application for a given soil as closely as possible to the optimum 
+rate given in table Preemergence, Preplant or Preplant Incorporated Broadcast 
+Application R~tes of BLADEX/Atrazine (2:1) 80W on Gorn. 
+BLADEX/Atrazine (2:1) may be applied preemergence with liquid 
+fertilizers. To apply 8U1DEX/Atrazine (2:1) 80W with liquid fertilizer fill 
+the spray tank at least one half full of liquid fertilizer and add the 
+recommended amount of I'.LAl)EX/Atrazine (2: 1) 80W to the tank, then fill with 
+liquid fertilizer to the desired level. 8LADEX/Atrazine (2:1) 80W must be 
+premixed in water as a slurry before being added to the fertilizer. 
+Sufficient jet or mechanical agitation should be provided dJring the filling 
+operation and during application. If the fertilizer requirement is less than 
+15 gallons per acre, add sufficient water to increase the volume of the 
+mixture to assure adequate volume for even distribution to the soil surface. 
+If incorporation of preplant application of the fertilizer mixture is 
+desired, use power cultivation equipment set for 2-3 inch depth, or a tandem 
+disc set to penetrate 2-4 inches "hUe operating at 4-6 mph. Do not store 
+BLADEX/Atrazine (2:1) 80W with liquid fertilizer in the sprayer or nurse 
+tank.

+Check to assure the compatibility of BUDEX/Atrazine (2: 1) 8011 wi~h the 
+liquid fertilizer prior to mixing in the spray tank. The follo\o,'ing j.:a test 
+is a good indicator of compatibility. Mix proportionate quantities as 
+indicated in a one pint jar. Invert jar ten times. Let stand 1/2 hour. If 
+any separation or agglomeration has occurred, again invert jar ten times. If 
+the mixture resuspends, commercial application is possible.
