inst/extdata/context_kotl.gpkg (4.9 MB) ships but nothing reads it

[NewGraphEnvironment]

If we do it: the installed package loses 4.9 MB, about 40% of its 12.5 MB installed size. If we never do: every install carries a file nothing reads.

Problem

inst/extdata/context_kotl.gpkg is 4.9 MB. Nothing in R/, tests/, vignettes/ or README.md references it. The only mention is its producer, data-raw/example_context_kotl.R, plus a comment in data-raw/example_context_fwcp_peace.R. It dates from 3ece27c (2026-04-07, before the Kootenay Lake vignette). The vignette added in #57 uses context_kootenay_lake.gpkg, which appears to supersede it. example_aoi_kotl.gpkg is still used by the README example, so keep it.

Found by a code-check reviewer while verifying #100's tarball contents, and confirmed with git grep -n context_kotl.

Proposed Solution

• Confirm context_kootenay_lake.gpkg supersedes it. Then delete inst/extdata/context_kotl.gpkg, and either delete data-raw/example_context_kotl.R or mark it superseded.
• Rebuild and compare the tarball size before and after.

Outcome (PR #115)

• Supersession confirmed. The file's consumer, the KOTL vignette, was removed in Remove KOTL vignette — peace-fwcp is the canonical worked example #50. context_kootenay_lake.gpkg has all five of its layers, plus wsgs and ecoregions, over an area that contains KOTL. No reader exists in this repo or, per an org-wide code search, in any other.
• Decision: deleted the producer, rather than marking it superseded. A kept script for a deleted output would recreate the 4.9 MB file if run. Git history keeps the recipe.
• Measured: the tarball went from 7.15 to 3.83 MB (−46%), and the installed package from 12.8 to 7.9 MB (−38%). The installed figure matches the "about 40%" above. The download shrinks by less than 4.9 MB because the gpkg compresses.
