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 +

+GENERAL INFORMATION 
+Read and follow all label recommendations. 
+TOUGH 45WP is a contact postemergence herbicide for the control of certain annual 
+broad leaf weeds. Following a specific preplant or preemergence herbicide treatment, 
+TOUGH 45WP will suppress or burn back sedges and some annual grasses. 
+TOUGH 45WP is rapidly absorbed by leaves. It penetrates into both sensitive and tolerant 
+plants, but is quickly metabolized and inactivated in tolerant crops such as corn and 
+cabbage. In sensitive weeds, activity is evident by marginal yellowing followed by 
+yellowing and browning of the entire leaf. This visible evidence generally occurs within 4-7 
+days of application. Activity is more rapid at higher temperatures and under good growing 
+conditions. Weed control under drought conditions may be decreased. 
+Uptake of TOUGH 45WP by leaves is very rapid and rainfall shortly after application (1-2 
+hours) has little effect on the degree of weed control. 
+TOUGH 45WP rapidly decomposes in the soil and has no effective preemergence or 
+residual activity. 
+TOUGH 45WP is nonflammable and nonvolatile. 
+Do not apply when crop is under stress from drought, cold weather, or severe pest 
+infestation

+Mixing Instructions: Fill the spray tank 1/2 full with water. Add the required amount of 
+TOUGH 45WP, mix thoroughly and add the remaining amount of water required for 
+application. Maintain sufficient agitation during mixing and spraying to ensure a uniform 
+spray mixture. 
+For tank mix combinations, the order of addition of other products is important. Wettable 
+powders or dry flowables should be added after the TOUGH 45WP, aqueous flowables 
+next, and then any emulsifiable liquids. Agitate between each addition until solution is 
+uniform and maintain constant agitation until solution is completely applied. Always mix 
+one product in water thoroughly before adding another product or compatibility problems 
+may occur. 
+After all products have been added, finish filling the spray tank with the remainder of the 
+water to be used for spraying. 
+NOTE: Agitation must be provided during mixing and spraying to ensure a uniform spray 
+mixture. Spray mixture should be used immediately and not stored. 
+Application - Procedures - TOUGH 45WP is noncorrosive to spray equipment. Before 
+preparing spray mixture, be sure all equipment is clean to prevent uneven application, 
+clogging of spray nozzles, or crop injury. Apply TOUGH 45WP with a boom sprayer 
+calibrated to a constant speed and constant, uniform delivery. TOUGH 45WP should be 
+applied in sufficient water (20-30 gallons per acre is recommended), at a pressure of 30-
+40 psi to ensure proper coverage. Thorough coverage of target weeds is required for 
+optimum results. Use the higher spray volumes when treating dense or tall vegetation. 
+Large crop and weed canopies can shelter smaller weeds. Directed applications below 
+large crop canopies are recommended for optimum coverage of target weeds. 
+Timing: TOUGH 45WP is most effective on actively growing broadleaf weeds. in the 2-4 
+true leaf stage . 
+. A delay in spraying which permits weeds to grow beyond the proper application time may 
+result in poor control. If weeds are under stress and not actively growing, they (lre .harder 
+to kill. Scout your fields 14-16 days after planting to determine exact timing for 
+application. In corn, a cultivation may be necessary if all weeds are not controlled or if 
+weeds regrow. 
+Do not apply when conditions favor drift which can carry spray to adjacent sensitive non-
+target areas. .'

+USE DIRECTIONS 
+Do not use this product in any type of irrigation system.-
+USE ON CABBAGE 
+Cabbage is more tolerant to TOUGH 45WP at certain stages of development. For optimum . 
+weed control and minimal comlJetition to the crop, timing of application should be based on 
+the stage of weed growth. However, for early application to the crop, the recommended 
+growth stage of the crop must be carefully observed. Failure to follow label directions may 
+result in severe crop damage. This is especially true for cabbage grown in the southern 
+states. Cabbage grown in the northern states are less susceptible to damage from TOUGH 
+45WP in the early stages of development. 
+CAUTION: TOUGH 45WP may cause temporary discoloring or yellowing of leaves that 
+were sprayed. Only leaves that come in contact with spray will be affected. The 
+discoloring of leaves does not affect yields. 
+Do not apply if rain has occurred within the last two days. 
+DO NOT USE SURFACTANTS OR OTHER ADJUVANTS. 
+In seeded cabbage, TOUGH 45WP should be applied only when the crop has at least 4 
+leaves fully developed and before head formation. 
+In transplanted cabbage, TOUGH 45WP should be applied only after plants have become 
+well established (about 3 weeks after transplanting) and before head formation. 
+For optimum broad spectrum weed control, TOUGH 45WP may be used as part of a 
+sequential treatment to control broad leaf weeds following a preplant incorporated or 
+preemergence herbicide. 
+For control of an-nual broadleaf weeds including triazine resistant types and annual grasses, 
+use the following treatment; 
+Apply trifluralin at recommended rates (see trifluralin label) preplanting and 
+incorporate, then follow with a postemergence application of TOUGH 45 WP at 2 
+Ib/acre to actively growing weeds. Apply TOUGH 45WP to broad leaf weeds in 2-4 
+leaf stage and annual grasses in 1-2 leaf stage in 20-30 gallons of water per acre. 
+Thorough coverage of targeted weeds is essential.

+TOUGH 45WP at 1 to 2 Ib per treated acre may be applied to actively growing broadleaf 
+weeds at any stage of corn growth after emergence in all tillage systems (conventional, no 
+tillage, or reduced tillage). Split applications of TOUGH 45WP maybe made, but do not 
+exceed applying a total of 2 Ib per treated acre per year.-Consult the Application section of 
+this label for best application timing for achieving optimum weed control. 
+TA~K MIX TREATMENTS IN CORN 
+TOUGH 45WP may be tank mixed with one or morEl-of, but not limited to, the following 
+herbicides for control of additional broadleaf weeds and/or grasses. Read and follow the 
+label of each tank mix product !lsed for precautionary statements. directions for use. rates 
+and timings. and other restrictions. 
+Adjuvants (non-ionic surfactants, crop oil or liquid fertilizer) may be used with TOUGH 
+45WP tank mixes where required by tank mix partners specified in this label. Read and 
+carefully follow all restrictions and recommendations of tank mix partners. Use of tank mix 
+partners is only allowed where permitted in each state. 
+Tank mixing TOUGH 45WP with other corn herbicides offers many benefits including 
+greater weed control spectrum, adding products with different modes of action to reduce or 
+delay the development of herbicide resistance by weeds, and optimizing performance of 
+tank mix partners thus allowing a lower use rate of each as directed in the label. 
+Optimization of performance is particularly beneficial when tank mixing a residual herbicide 
+such as atrazine thus decreasing carryover and other concerns associated with residual 
+herbicides. Suggested tank mixes include but are not limited to: 
+TOUGH 45WP plus atrazine: For additional broad leaf weed control (see Weed List) apply 1
