shortbread

Version	2026.144.1443
Repo	superproject

Generate Shortbread-schema OSM vector tiles with a source-built Tilemaker plus the official shortbread config bundle. Builds systemed/tilemaker (C++/Lua) from source — there is no Arch/Fedora package and no release binary — and installs it at /usr/local/bin/tilemaker. Clones the official shortbread-tiles/shortbread-tilemaker bundle (the process.lua per-feature classifier + the config.json layer/zoom schema) to /opt/shortbread-tilemaker with its .git history stripped. With both in place the notebook DAG can convert an OSM PBF into monaco-shortbread.pmtiles under the versatiles-watched /workspace/tiles/shortbread directory. The Shortbread schema is the de-facto general-purpose OSM vector-tile schema documented at https://shortbread-tiles.org.

Acceptance plan

This candy’s plan: — the runnable spec charly check executes against a live deployment. check: steps are idempotent probes; run: steps change state.

Intent	Step
run	command=set -euo pipefail git clone –depth 1 https://github.com/systemed/tilemaker /tmp/tilemaker cd /tmp/tilemaker # Boost 1.91+ (CachyOS / Arch as of 2026-Q1) made # boost::system a HEADER-ONLY library: libboost_system.so # no longer exists. tilemaker’s Makefile still ships # -lboost_system in its link line, which fails with # cannot find -lboost_system. Strip the flag — the # boost::system functionality lives in headers, no link # step needed. boost_filesystem + boost_program_options # still ship as .so libraries, so we keep those. sed -i ‘s/-lboost_system//g’ Makefile make -j“$(nproc)“ make install PREFIX=/usr/local cd / rm -rf /tmp/tilemaker
run	command=set -euo pipefail git clone –depth 1 https://github.com/shortbread-tiles/shortbread-tilemaker /opt/shortbread-tilemaker rm -rf /opt/shortbread-tilemaker/.git
run	mkdir=/workspace/tiles/shortbread
check	the tilemaker binary built from systemed/tilemaker source is installed under /usr/local/bin
check	tilemaker resolves on PATH so the notebook DAG can invoke it (tilemaker ships no –version flag, so resolve by name)
check	the shortbread per-feature Lua classifier is bundled for tilemaker –process
check	the shortbread layer and zoom schema definition is bundled for tilemaker –config
check	the cloned bundle has its .git history stripped to keep the image small
check	the versatiles-watched output directory is pre-created at build time so versatiles serve starts cleanly on a fresh deploy
agent-check	a tilemaker run converts an OSM PBF into a monaco-shortbread.pmtiles archive in that directory using the bundled config.json and process.lua
check	package=lua
check	command=test -d /workspace/tiles/shortbread
