Image rebuild (skip scrape) / build (push) Failing after 1h37m12s
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).

NOTE: Local conditions, crop varieties ilnd application requlations VillY and may
affect usc of this horbicido. Consul-! loc,)! aqrlcultural expC:I'lmnnt station or L----­
extension service woed specialists and state regulatory ~qencies for recommenda-
tions In your area.
TREATING S:I,ALL AREAS: One tablespconful of RIVERSIDE 2,4-0 BUTYL ESTER 6 In tt 1. ___
gallons of water Is about equal to 1 quart in 100 '-Iallons.
NOTE: vlhen stored at temperatures be I ow f reez i n9, it may be necessary to warm L_
contents to 45°F and mix thoroughly before using.
PREPARATION OF THE SPRAY: Fil I the spray tank with half the required amount of water,
then add the recommended amount of RIVERSIDE 2.4-0 8UTYL ESTER 6 and continue fl II ing
spray tank with bu I <lnce of water. Keep ag i tator runn i ng when f i I I i nq spray tank and
dur i ng spray operat ions. Use enough spray vo I ume for un i form COVeril!)e. I n any case, •
USe the same amount of :>,4-0 recommended per acre. For crop uses, DO NOT mix with
oil, atraz I ne, surfactant or- other adjuvants un I ess spec if i ca II y recOI"IIIended on th I s
label as this may reduce selectiVity to crops resulting in crop damage.
TIME OF APPLICATION: Best results are obtained when RIVERSIDE 2,4-D BUTYL ESTER G
is used on young ~!eeds that are actively growing. Applications of lower recOIMlended \
rates to susceptible annual weeds usually will be satisfactory, but for perennial -­
' .. eeds and other conditions, such as in very dry areas where ki II is difficult, use
higher recommended rates. ~Ihen used as a selective spray on crops, the stage of growth
of the crop must be considered. Some woody plants and weeds are hare to kill and
repeat applications may be necessary.
S~!ALL GRAINS (Wheat, Barley, Rye): Apply RIVERSIDE 2.4-D BUTYL ESTER 6 in sufficient
water for unl form_ c;overa9..e on __ sma II gra i ns when fu Ily ti Ilered or stooled (Tfa -8-
inches ta II ), but befo·re the "boot" stage. DO NOT use on gra In undersown with legumes
such as alfalfa or clovers, except where some legume injury can be tolerated. DO NOT
graze or feed forage from treated fields within two weeks after treatment. See chart L/­
for recommended rates.
for late season use to control large succulent weeds, apply 2/3 to 1 1/3 pints per
acre in sufficient water for uniform coverage on small grain from dough stage to ~
harvest --Use only when weeds threaten to interfere with harvest operations. DO NOT ~
use treated straw for I ivestock feed.
CORN: PREEr~ERGENCE-Use RIVERSIDE 2,4-D BUTYL ESTER 6 in 'iufficient water for uniform 7
_caverage Best results are obtained when applied 3 to 5 days after planting, but betore
corn emerges. 00 NOT apply to light, sandy soi Is. t.,...---".
POSTEMERGENCE-Apply RIVERSIDE 2,4-D BUTYL ESTER 6 from emergence to tassel ing. When
spraying corn taller- than 10 inches, use nozzle extensions (llcorn drops"), directing
the spray at base of the corn plant to keep the spray off the leaves as much as
possible. DO NOT apply from tassel emergence to dough stage. Crop injury is more
likely to occur if corn Is growing rapidly under high temperature and high soil
moisture conditions. Under such conditions, use the lowest recommended rate. Delay ~­
cultivation for 8 to 10 days after application to reduce stalk breakage re?ul~ing from
temporary brittleness caused by 2,4-0. Hybrids vary in tolerance to 2,4-D.:~~ult

PASTURES: To control many broad leaved weeds in pastures. meadows and rangelands. use
I 1/3 pints per acre of RIVERSIDE 2,4-0 BUTYL ESTER 6 in sufficient water to provide
uniform application. Treat pastures when weeds are growing actively. DO NOT apply
to newly seeded pastures unti I grass is \~cl I cstabl ished or after heading begins. '-­
DO NOT apply when grass is in "boot" to "mi Ik" stage if grass production is desired.
Most legumes are usually injured or kil led at the rates recommended. For control
of wi Id garlic and wild onion in pastures. apply I 1/3 to 2 quarts per acre in very
early spring and repeat annually untl I weeds are eradicated. DO NOT graze dairy~
animals on treated areas within 7 days after treatment.
\~OODY PLANT CONTROL: To contro I 2,4-0 suscept i b I e woody p I ants such as a I der, buck­
brush, elderberry, sumac and wil low on non-crop land and waste areas, uSe 1 1/3 to
2 quarts of RIVERSIDE 2.4-0 BUTYL ESTER 6 in 100 gallons of water. Wet thoroughly /'
al I parts of the plants, including foliage and stems, to the point of run-off. Higher
volumes are necessary where the brush is very dense and 0\ >r 6 to 8 feet high. Appli­
cations are more effective when applied to actively growing plants. DO NOT treat
during periods of severe drought or in early fall when leaves have lost their healthy
green color. Hard-to-kill species may need retreatment the fol lowing season.
GENERAL WEED CONTROL: Along fence rows, ditchbanks, around farm buildings and similar//­
areas, use 1 1/3 to 2 2/3 pints of RIVERSIDE 2,4-0 BUTYL ESTER 6 in 100 gallons of ~
water per acre. Tholoughly wet al I fol iage to run-off.
