ci/woodpecker/pr/ci Pipeline was successful
mos-dt's post-verdict residual (non-blocking, comments 19484/19487): grep is
LINE-oriented, so ^[0-9]{1,9}$ binds per line and a knob with an embedded
newline ($'300\n8', $'300\nabc') passes the regex whole yet is FATAL inside
$((...)) under set -u — the same poll-killing class #942 fixed, reachable only
via the env-config operand (snap_ts is immune: jq's number type-check cannot
emit an embedded newline).
Fix (mos-dt-verified pattern): replace grep with a whole-string case pattern —
'' and *[!0-9]* reject, length <= 9 — identical accept/reject to the regex on
every single-line value, rejects both multi-line cases. 10# radix force
unchanged. Two new D13 sub-cases (SHA-CC2/SHA-CC3) cover exactly the repros;
det_seq assertion 6 -> 8. Manifest states the string-extent rule: the validator
and the consumer must agree on STRING EXTENT, not just shape and radix.
Suite: 13 groups, D13 green 4/4 local runs; sole intermittent failure is the
known pre-existing D4 fd-9 flake (carried separately by mos-dt).
