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).

+maturity. 
+Timing To Weeds 
+Apply SYNCHRONY S'j'S when weeds arc young and 
+actively growing (after the fi"t in,e leaves have expanded, 
+but before the weeds exceed the si>£ indicaled below). 
+Applications madc to weeds larger than the si/£s imlKated

+SYNCHRONY STS will provide best results when applied 
+to young, actively growing weeds. Degree of control 
+depends on: weed spectrum; weed .ize (ifweeds llfe large, 
+use higher spray volume); growing conditions at and, .

+SPRAYER PREPARATION AND CLEANUP 
+Prior to application of SYNCHRONY STS, start with clean,

+makes effective cleanup more difficult. Failure to clean 
+spraying equipment thoroughly may result in injury to 
+suhsequently sprayed crops. 
+When spraying multiple loads of SYNCHRONY STS over 
+an extended period of time, rinse the equipment with clean 
+water at the end of the day. Leave waler in the equipment 
+overnight to prevent deposits from drying on surfaces. 
+When applications of SYNCHRONY STS are completed and

+SPRAY DRIFT MANAGEMENT 
+The interaction of many equipment and weather-related 
+factors detennincs the potential for spray drift. The 
+aprlicator is responsible for considering allthcsc factors 
+when making application decisions. 
+A VOIDING SPRAY DRln IS THE RESPONSIBILITY 
+OF ll1E APPLICATOR. 
+IMPORTANCE OF DROPLET SIZE 
+TIle most effective way to reduce drift potential is to apply 
+large droplets (> I sO - 200 microns). The best drift 
+management strategy is to apply the largest droplets that 
+provide sufficient coverag~nd control. The presence of 
+sensitive species nearby. the environmental conditions. and 
+pest pressure may affect how an applicator balances drift 
+control and coverage. APPLYING LARGER DROPLETS 
+REDUCES DRIFT POTENTIAL. BUT WILL NOT 
+PREVENT DRIFf IF APPLICATIONS ARE MADE 
+IMPROPERLY OR UNDER UNFAVORABLE 
+ENVIRONMENTAL CONDITIONS! See Wind. 
+Temperature and Humidity, and Temperature Inversions 
+sections of this label. 
+Controlling Droplet Size - General Techniques 
+Volume - Use high !low rate nozzles 10 apply the highest 
+practical spray volume. Nozzles with higher rated !lows 
+produce larger droplets. 
+Pressure - Use the lower spray pressures recommended 
+for the nozzle. Higher pressure reduces droplet size and 
+does not improve canopy penetration. WHEN HIGHER 
+FLOW RATES ARE NEEDED, USE A HIGHER­
+CAPACITY NOZZLE INSTEAD OF INCREASING 
+PRESSURE. 
+Nozzle Type - Usc a nozzle ')"pe that is designed for the 
+intended application. With most nozzle types, nanower 
+spray angles pnxiucc IJrgcr droplets. Consider using low­
+drift nozzles. 
+Controlling Droplet Size - Aircraft 
+Number of Nozzles - Usc the minimum number of nozzles 
+with the highest flow rate that provide unifonn coverage. 
+;\lozzlc Orientation - Oncnting n07lles so that the spray is 
+emitted hackwards, parallel to the airstream will produce 
+larger droplets than other orientations. 
+Nonie Type - Solid stream nozzles (such as disc and core 
+with swirl plate removed) oriented straight hack produce 
+larger droplets than other noaic types. 
+Boom Length - 'Inc boom length should not exceed 3/4 of 
+the \\ling or rotor length - longer booms increase drift 
+potentia1.

+WIND 
+Drift poIentia! increases at wind speeds of less than 3 mph 
+(due :0 inversion potential) or more than IO mph. However. 
+",any factors. including droplet size and '''Iuipment type 
+deternline drift potential at any given wind speed. A VOID 
+GUSTY OR WINDLESS CONDITIONS. 
+Note: Local terrain can influence wind patterns. Every 
+applicator should be familiar with local wind patterns and 
+how they affect spray drift. 
+TEMPERATURE AND HUMIDITY 
+When making applications in hot and dry conditions. set up 
+equipment to produce larger droplets to reduce effects of 
+evaporation. 
+TEMPERATURE INVERSIONS 
+Drift potential is high tluring a temperature inversion. 
+Temperature inversions restrict vertical air mixing. which 
+causes small suspended droplets to remain close to the 
+ground and move laterally in a concentrated cloud. 
+Temperature inversions are characterized by increaSing 
+temperature with altitude and are common on nights with 
+limited cloud cover and light to no wind. They begin to form 
+as the sun sets and often continue into the morning. Their 
+presence can he indicated by ground fog; however. if fog is 
+not presen!, inversions can also be identified by the 
+movement of smoke from a ground source or an aircraft 
+smoke g-~ncrator. Smoke that layers and moves laterally III a 
+concentrated cloud (under low wind conditions) indicates an 
+inversion. while smoke that moves upward and rapidly 
+dissipates indicates good vertical air mixing. 
+SHIELDED SPRA YERS 
+Shielding the boom or individual nozzles can reduce the 
+effects of wind. However, it is the responsibility of the 
+applicator to verify that the shields are preventing drift and 
+not interfering with UllJfOml deposition of the product. 
+AIR ASSISTED (AIR BLAST) 
+FIELD CROP SPRA YERS 
+Air assisted field crop sprayers carry droplets to the target via 
+a downward directed air streatll. Some Illay reduce the 
+potentiai for drift, but if a sprayer is ull;uitable for the 
+application andlor set up improperly. high Jrift potential can 
+result. It is the responsibility of the applicator to determine 
+that a sprayer is suitahle for the intended application. is 
+configured properly, and that drift is not occurring. 
+Note: Air a"jsted field sprayers can affect product 
+perfonnanec by atfcctir.g spray coverage and canopy 
+pcnetralion. Consult the application equipment section of 
+tim label to detenninc if use of an alf assisted sprayrr is 
+recom mended.

+I 
+AIR ASSISTED (AIR BLAST) 
+TREE AND VINE SPRAYERS 
+Air assisted tree and vine sprayers carry droplets into the 
+canopy of trees and vines via a radially or laterally directed 
+air stream. 111ese sprayers are not suitable for applying 
+herbicides. 
+In addition to the general drift management prine iples 
+already described, the following specific practices will 
+funher reduce the potential for drift.: 
+Adjust deflectors and aiming devices so that spray is only 
+directed inlO the canopy. 
+Block ojJupward pointed noules when there is no 
+overhanging canopy. ; 
+Use only enough air volume to penetrale the canopy and 
+provide good coverage. 
+Do not aI/ow spray to go beyond the edge of the cultivated 
+area. Spray the outside row only from outside the 
+planting. 
+IMPORTANT PRECAUTIONS 
+Do not grazetreared fields or harvestfor forage or hay. 
+Do nolappljtlJisproduct throughan~typecif irrigation 
+equipment 
+Injury to or loss of desimble trees or vegetation may result from 
+failure to observe the following: 
+Do not apply SYNCHRONY STS Or dmin or flush equipment 
+on or n~ar desimble trees or other planls, on areas where theu 
+roots may extend, or in locations where the chemical may he 
+washed or moved into contact with their roots. 
+Do not use on lawns. walks. driveways, tennis courts or 
+similar arcm;. 
+Many crops are sensitive to SYNCHRONY STS. All direct or 
+indirect contact (stich as spmy drift) with crops other than 
+soybeans should be avoided. 
+TIKlfoughly clean all application equipment immediately aher 
+llse and prior to spraying crops other th~n soybeans. 
+SYNCHRONY STS is for use only on soybean varieti,,., 
+designated as "STS". 
+INFORMATION ON RESISTANT WEEDS 
+When helbicides with the same mode of action arc uscd 
+repeatedly over several yea.-s to coniiol Ule same weed species in 
+the same field, narumlly·occurring resis~mt weed hiotypes may 
+survive a correctly applied herbicide treatment, propagate. and 
+become dominant in Ulat field. These resistant wced hiotypes 
+lIIay not be adequately controlled. Cultural practices such as 
+tillage, prcvc:nting weed escapes from going to secd. and usmg 
+hcrhicidcs with differrnt modes of action within and hetween 
+crop seasons can aid in delaying ttlC proliferation and possihle 
+dominancc of herbicide resistant weed biotyp<'s.
