# The binary locates its calendar data relative to its own path
# (<prefix>/share/colitur/ef), so `dune install` -- not a hand-rolled copy --
# is what places the four .sexp files where a running colitur will look for
# them. See bin/main.ml's own [data_dir] for the full resolution order.
# Task 13 (schema/dune, templates/dune) extends the same `dune install`
# mechanism to <prefix>/share/colitur/schema/ (bin/main.ml's own
# [schema_path], read by `colitur publish`) and <prefix>/share/colitur/
# templates/ (a convenience install -- `--template` takes a plain file path,
# nothing in colitur probes this location the way [data_dir]/[schema_path] do).
#
# dune needs the project-local opam switch on PATH. Every recipe that invokes
# dune goes through this, so `make` works from a plain shell with no
# `eval $(opam env)` first -- which is the whole point of having a Makefile
# over documenting the dune commands.

# Typesets every shipped template through the real tool that would typeset it
# for a reader, not merely through this program's own renderer. The golden
# tests already prove `colitur table` PRODUCES the expected LaTeX/groff/HTML/
# Typst text; only this proves that text actually TYPESETS -- a template can
# render byte-for-byte as pinned and still be malformed LaTeX, groff or
# Typst. Each tool is genuinely optional (none is in colitur's own frozen
# deps), so absence is printed LOUDLY as SKIPPED rather than silently
# treated as a pass -- a silent skip reads as a pass, which is the whole
# failure mode this guards against.

# ordo.ms's own -P-pa5 (added alongside grid.ms's existing -P-pa4l, the
# same mechanism, not a new one) and -Kutf8 (both flavours) fix two
# defects this target's own "did it TYPESET" check could never see on its
# own: groff's default PDF device paper is not A5 (so the booklet was
# roughly twice the intended page area -- half a real density problem
# was hiding in the page, not the type) and groff's default input
# encoding is not UTF-8 (so an accented Latin name like Pe\(~nafort
# rendered as visibly wrong characters) -- neither one is a groff
# WARNING, so this target's own "any stderr is a failure" check was
# silently green through both. Rendering to an actual PDF and reading it
# is what caught them; a byte-identical-to-golden pass would not have.

# lang/la.ini's own discipline: every celebration/season/rank name cites the
# docs/research/LT.txt line it was transcribed from, so a claim can be
# checked, not just trusted. tools/check_citations.py re-derives that check
# mechanically: for every "LT.txt:<n>" citation outside a PATTERN-marked
# block, it confirms the EXACT cited line (or an explicit "n-m" range, for
# a heading that genuinely wraps -- no automatic +-2-line tolerance any
# more, see the script's own docstring for why) contains the Latin text the
# citation claims, scoped to that citation's own entry only, never to
# prose quoted elsewhere in the surrounding comment. A citation whose pool
# of candidate words is too thin to discriminate a right line from a wrong
# nearby one (a heuristic, not a proof) is reported CANNOT VERIFY, not
# silently passed, and fails the target exactly like a genuine mismatch --
# a human adjudicates it. The script has its own self-test
# (tools/test_check_citations.py, wired into `dune test`/`make test` as
# well as this target) after an earlier version of this exact check was
# found to be self-poisoning: see either docstring for the full account.
# docs/ is gitignored, so a fresh clone has no docs/research/LT.txt at
# all: the same "SKIPPED, loudly, exit 0" discipline check-schema/
# check-templates already use above -- a silent skip reads as a pass,
# which this project has hit the cost of before.
