A script written against LABEL and GOTO NAME never names a line number, so
the numbers it had to carry were decoration. akbasic_runtime_load(),
RUNSTREAM and DLOAD now file an unnumbered line one slot after the last one
filed; a numbered line is filed under its number and moves the cursor, so
the two mix. akbasic_runtime_file_line() is the one implementation of that
rule, so the three paths cannot drift.
The prompt is untouched. A line typed without a number is still direct mode
and still runs now -- that is the only thing separating program text from a
statement at a REPL, and it is why this is a loading feature.
What this replaces was silent data loss: an unnumbered line was filed under
the cursor unchanged, on top of the line before it. A blank line therefore
erased whatever preceded it, and RUNSTREAM did not skip blank lines the way
the other two paths did.
That moves one golden file, and the reference had the same defect.
language/arithmetic/integer.bas has four PRINT statements, an expectation
with three values, and a trailing blank line that erased 40 PRINT 4 - 2
before the program ran. The expectation is now 4 4 2 2.
tests/reference/README.md records the divergence and TODO.md section 5 item
63 says why.
akbasic_SourceLine grows a `numbered` flag so an assigned number can be told
from a written one. RENUMBER sets it on every line it touches; NEW, DELETE
and DLOAD clear it. hadlinenumber moves to akbasic_scanner_scan(), so it
always describes the line just scanned rather than only the REPL's.
Two lines carrying the same written number still keep the last, as they
always have. That is a separate decision.

The Go reference is deprecated and will not be updated, so the two projects
are no longer required to match. Recorded as TODO.md section 0.1, first thing
in the file, because it silently reverses the premise several later sections
were written on -- an agent reading section 6 without it will park work that
is no longer blocked.
Section 6 item 16 was the item waiting on exactly this and is now fixed: the
keyword tables are searched on the base name with any type suffix stripped, so
PRINT$, LEN# and GOTO% are refused as variable names and the reference's own
diagnostic stops being dead code. It cost the one golden case predicted, and
the cost was nothing -- renaming a variable in strreverse.bas left its expected
output byte-for-byte unchanged.
AKBASIC_KNOWN_FAILING_TESTS is empty as a result and known_reference_defects.c
is gone. Section 6 items 1-9 and 11 are reopened as an ordinary defect list.

All 41 .bas/.txt pairs copied byte for byte from basicinterpreter@d76162c into
tests/reference/, plus the Commodore font into assets/fonts/ -- the two things
that tied the build to deps/basicinterpret. Both were verified cmp-identical
to the submodule copies.
This reverses a decision that was deliberate and correct at the time: the
corpus was driven in place because copying a submodule's corpus guarantees
drift. Overruled on purpose -- the Go dependency is being deprecated, and a
build that cannot run its acceptance suite without cloning the implementation
it replaced is not finished. tests/reference/README.md records what the drift
now costs and that those expectations are never edited.
Checked rather than assumed: both configurations configure, build and pass
from scratch with deps/basicinterpret moved out of the tree entirely.
The submodule is kept as the behavioural spec, which is a real use. The font
came with an open licence question; assets/fonts/PROVENANCE.md states it.
