The UICC_NAA.md C3/C3a recipes were re-checked against the corpus: the
EPSLOCI dummy tail is FF*13 + `FF FE` + status - the TAC is always FFFE
(never FF) and the status byte is 01 (not updated), not FF; the old
`<FF*16>` reading was a misparse of that tail. The rejection form
(status 02) is the C3a spec model: the only observed rejection trace never
writes 6FE3 at all.
- build_epsloci_dummy(status=ST_NOT_UPDATED, keep_plmn=None): corrected
tail; keep_plmn selects the NMR style that preserves the last visited
TAI PLMN (the guest style wipes GUTI and TAI PLMN) - both are observed
- write_dummy_locations(): drop the all-FF special case (service loss now
ends `FF FE 01`) and thread keep_plmn through
- tests: exact guest/NMR/rejection vectors, 18-byte length, runner
assertions for service_lost and roaming_denied; netstate fixture updated
- UICC_NAA.md C3a tail `<FF*15> 02` corrected to `<FF*13> FF FE 02`;
the PWA help/param text no longer claims the EPSLOCI dummy keeps the
PLMN; SW cache simple-v205
