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).

+Dear Mr. Rogosheske: 
+MAR 5 2002 
+SUbject: Label Amendment Extending 2,4-D Use in Reduced or No-Tillage Soybeans 
+(Pre-plant Only) 
+Wilfarm 2,4-D Amine 4 
+EPA Reg. No. 1381-155 
+The Agency is conditionally amending the registration of the above-referenced product under 
+the authority of section 3(c)(7)(B) of the Federal Insecticide, Fungicide, and Rodenticide Act 
+(FIFRA). This amendment allows the continued use of the subject product on reduced or 
+no-tillage soybeans (pre-plant only) with a maximum permissible level for residues of the herbicide 
+in or on soybeans of 0.02 ppm until December 31,2004. This conditional registration will expire 
+automatically on December 31,2004. Sale or distribution of the subject product bearing labeling for 
+this use on reduced or no-tillage soybeans (pre-plant only) after December 31, 2004 will be illegal. 
+The tolerance authorizing residues of the subject product will also expire on 
+December 31, 2004. If and when a permanent tolerance is established, EPA will entertain an 
+application to amend the registration of the subject product to remove all special limitations on the 
+duration of the soybean use. 
+This amendment only extends the expiration date ofthe time-limited registration for soybeans. 
+No label revisions are permitted by this amendment. For this reason, the Agency is not requiring you 
+to submit draft labeling with the new expiration date for this action. Therefore, the Agency's latest 
+stamped accepted copy of your label for this product for preplant use on soybeans (with the prior 
+expiration date of December 31, 200 I) will continue to constitute proof of the Agency's acceptance 
+of the label for subject product. 
+Sincerely yours, 
+Joanne I. Miller 
+Product Manager (23)

+Registration Division (7505C)
