Add the two matrices whose absence hid the leaks: single-quoted and ANSI-C
roots, full-header and value-only, with an adjacent serialized double-quoted
segment at depths 0 to 3; and line continuations with LF and CRLF after an
unquoted value, after each closed quoted argument, inside a double-quoted
value, and on the value's first byte.
Turn the permissive tables into transformation oracles. The truncated-tail,
even-run space and line-end, and fixpoint tables now assert exact output
where it is determinate. Rows stay on removal and stability only where the
union makes the exact output a policy artifact rather than a fact about the
credential: every serialized truncated row, which loses its outer delimiter,
and the adjacent segment carrying an escaped quote, where scanning the tail
at every layer runs a deeper reading to the line end. Each of those carries
the reason inline.
