# The CALC ladder — the ratchet for the work in CALC-COMPILE.md.
#
# One row per program, in the same shape run_compile_tests.sh asserts against
# tests/fixtures/expected.tsv:
#
#   <program>	OK	<code>	<data>
#   <program>	ERR	<tp3-error-no>	<normalised-pos>
#
# tests/calc_ladder.sh stages a COPY of the named program — and of the
# companions that must sit beside it — into tmp/calc_ladder/ and runs the
# freshly built compiler on it.  A copy, not the Resources file itself: the
# include (Stage 2 of CALC-COMPILE.md) resolves relative to the including file,
# so CALC.INC has to be beside CALC.PAS in the staged tree.
#
# The rung may only move FORWARD.  Each stage that removes a blocker replaces
# the row in the SAME commit as the fix and says why in the message.  Never
# edit a row to make a failing suite pass; that is the one thing this file
# exists to prevent.
#
# pos is NOT a file offset.  TextBuf.LoadFile collapses CRLF and a lone LF to a
# single CR, so pos indexes the NORMALISED buffer: CALC.PAS is 11,241 bytes on
# disk and 11,059 normalised, so the reported 7791 is file byte 7901.  Every
# position written here is a normalised one.  Once {$I CALC.INC} lands the
# buffer is CALC.PAS with the directive replaced by CALC.INC, so all downstream
# positions shift — which is exactly why this must be a measured number, not a
# remembered one.
#
# Current rung (2026-10-23): `Copy(Formula,...)' inside Factor's real Val.
