v3.34.0: Edit decoded wave 2 — service tables, scalars, PLMN lists, BCD, CB lists

Browse Source 
New client-side editors: the service tables EF.UST/IST/EST (a filterable
bit grid; unmodelled bits and the file length preserved), EF.ACC,
EF.PHASE, EF.HPPLMN, EF.AD (op-mode enum, additional info, MNC length
incl. 0 and the 3-byte SIM form), the PLMN-only lists
EF.PLMNsel/FPLMN/EHPLMN, EF.ICCID/EF.IMSI behind a confirmation, and the
cell-broadcast lists EF.CBMI/CBMID/CBMIR.

Framework: a bits form kind, a per-entry model(dec) hook, a per-entry
confirm prompt and hex fields.

Decoder fixes: EF.ACC class numbering (byte1 b8..b1 = 15..8, byte2 =
7..0), EF.AD operation mode (whole byte) and its MNC length rules,
EF.SST decoded with the SIM 2-bit allocated/activated layout (editing
stays disabled until that UI exists), and the EF.IMSI parity nibble
(9 odd / 1 even).  A no-edit save of the new list files no longer
writes all-FF (the collected rows and the encoders disagreed on the
value shape).

Decoded editing for EF.DIR/EF.ARR/EF.SMS/EF.PBR is postponed by
decision (read-only viewing is enough); the survey records it.

1022 Python + 1033 frontend green; simple-v467.

## [Unreleased]
## [3.34.0] — 2026-10-23
### Added
- **Edit decoded, wave 2** — new editors for the service tables **EF.UST / EF.IST /
EF.EST** (a filterable bit grid preserving services the table does not model), the
scalars **EF.ACC**, **EF.PHASE**, **EF.HPPLMN** and **EF.AD**, the PLMN lists
**EF.PLMNsel / EF.FPLMN / EF.EHPLMN**, the identities **EF.ICCID / EF.IMSI** (behind a
confirmation — writing them changes the card identity) and the cell-broadcast lists
**EF.CBMI / EF.CBMID / EF.CBMIR**. **EF.SST** is deliberately left read-only: its
SIM layout is 2 bits per service (allocated + activated), which needs its own editor.
- The file-format survey (`docs/decoded-editing.md`) now records the shipped waves and
marks **EF.DIR / EF.ARR / EF.SMS / EF.PBR** as postponed by decision (read-only).
### Fixed
- **EF.ACC** class numbering (TS 31.102 4.2.15): byte 1 b8…b1 codes classes 15…8 and
byte 2 classes 7…0 — the decoder counted class 0 at the MSB (an all-FF ACC read as
class 0 instead of classes 0–15).
- **EF.AD** (TS 31.102 4.2.18): the operation mode is a whole-byte enum
(00/80/01/81/02/04), not bits 0-1 plus a test bit; the MNC length may be 0 (service
n°130 available) or absent (3-byte SIM form) — the editor previously refused both.
- **EF.SST** (TS 51.011 10.3.7): the SIM service table is decoded with its 2-bits-per-
service layout (allocated + activated) instead of the UST 1-bit codec.
- **EF.IMSI**: the parity/type nibble is `9` for an odd digit count and `1` for an even
one (TS 24.008 10.5.1.4); the encoder always wrote `9`.
- Saving a PLMN/CB list with no edits no longer rewrites it as all-FF (the collected rows
and the list encoders disagreed on the value shape).
