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).

+Subject: Modification to the Agency’s June 29, 2021 Label Amendment Letter – 
+Change Existing Stocks Term for Non-Forest Management Use 
+Cancellation Related Edits 
+ Product Name: Saddle-Up 
+ EPA Registration Number: 1381-255 
+ Application Date: October 29, 2018 
+ Decision Number: 546387 
+ 
+Dear Ms. Mathias: 
+ 
+At Winfield Solutions, LLC’s request, the Agency is amending the conditions for existing stocks 
+stated in the Agency’s June 29, 2021 letter for the subject product. Specifically, that letter stated 
+that, “As of February 22, 2021, you may only distribute or sell this product if it bears this new 
+revised labeling or subsequently approved labeling,” to align with the same expiration date stated 
+in the Cancellation Order published on August 21, 2019 (FRL-9996-82), for the removal of 
+forest management use from this product. 
+ 
+The approved label dated June 29, 2021, includes additional changes requested by the Agency to 
+update the label to current standards. The requested changes were not related to the primary 
+substantive change requested by the registrant, removal of the forest management use. Upon 
+further consideration, the Agency is amending the expiration date for sale and distribution of the 
+product as follows. Product bearing labels with the forest management use may not be sold or 
+distributed after February 22, 2021. Product bearing labels with the forest management use 
+removed but without the additional changes included in the June 29, 2021 letter and 
+corresponding stamped label may be sold or distributed until December 29, 2022. After 
+December 29, 2022, the product may only be sold or distributed if it bears the new revised 
+labeling approved in the June 29, 2021 letter, or subsequently approved labeling. 
+ 
+Paragraph 2 of the Agency’s June 29, 2021 letter is hereby amended to read: 
+ 
+“A stamped copy of your labeling is enclosed for your records. This labeling supersedes all 
+previously accepted labeling. You must submit one copy of the final printed labeling before you 
+release the product for shipment with the new labeling. Although the Cancellation Order 
+published on August 21, 2019 (FRL-9996-82) declared that EPA has previously approved the 
+label containing this use deletion, the amended label is being approved with this letter. As of
+
+Page 2 of 2 
+EPA Reg. No. 1381-255 
+Decision No. 546387 
+ 
+February 22, 2021, you may only distribute or sell this product if it bears this new revised 
+labeling, or previously approved labeling with the forest management use removed, or 
+subsequently approved labeling. 
+ 
+In accordance with 40 CFR 152.130(c), you may distribute or sell this product under previously 
+approved labeling until December 29, 2022, if the label excludes forest management use. After 
+December 29, 2022, you may only distribute or sell this product if it bears this new revised 
+labeling or subsequently approved labeling. “To distribute or sell” is defined under FIFRA 
+section 2(gg) and its implementing regulation at 40 CFR 152.3.”
