The TR's response objects are all Min = N in the spec's own table, and
6.8.0 says such objects "should set the CR flag to comprehension not
required" - so the builders now emit the base tag forms:
- device identities 82 -> 02 (every builder)
- PLI data 93/94/AD/AE/BF/E2/E5 -> 13/14/2D/2E/3F/62/65 (26/63 already
base); the PWA inline codecs follow
- POLL INTERVAL Duration 84 -> 04
- GET INKEY/INPUT Text string 8D -> 0D
- SELECT ITEM Item identifier 90 -> 10
- Timer identifier/value A4/A5 -> 24/25
(_bip_tr already used the reference traces' 01/02/03.)
The command details now echo the command's tag form (01/81) besides
its qualifier - 6.8.1 requires the object to be identical to the
command's "including the comprehension required flag": the parser
returns cd_tag and _build_tr, _handle_timer_command,
_handle_bip_command, the menu pendings and testscript.build_tr carry
it. The Result keeps 03/83 (Min = Y). _tr_data_only strips both tag
styles and the POLL Duration decode accepts 04.
Tests: the base forms per builder + the echo + the PWA drift guards;
883 frontend + 866 Python; sw cache simple-v426.
The stuck-card pattern: after a Back TR the card re-issues the parent menu
as a new SELECT ITEM (91XX -> FETCH, paused, awaiting TR), but the UI's
back/timeout branch ignored that response and showed the cached top menu;
the next item click then sent ENVELOPE(Menu Selection) while the card was
waiting for the TR. The card answers such an ENVELOPE with 9000 (not the
usual 91XX), and menu-select cleared the pending command without a TR,
leaving an unfinished proactive session until reset/equip.
- server: _finish_pending_menu() answers a paused command with a cancel TR
(0x10) before /api/menu-select sends its ENVELOPE and drains a 91XX
follow-up, so a new selection can never shadow an unanswered FETCH
- frontend: stkMenuRespond('back'|'timeout') renders the follow-up command
from the server response (SELECT ITEM / DISPLAY TEXT) and shows the
cached top menu only when the TR answer carries no command (9000)
- tests: finish-pending cancel TR + chain drain (Python); stkMenuRespond
back/timeout/cancel/ok rendering (frontend); help/AGENTS updated;
SW cache v107 -> v108.
Every FETCHed proactive command must be answered, otherwise the card is
left in an unfinished session and stops issuing commands (e.g. it will
not deliver a PoR for SEND SM). The menu handlers now share
_menu_send_response, and a server-side watchdog (_arm_menu_timeout /
_menu_timeout_fire, --menu-timeout, default 60s, 0 disables) sends the
timeout result (0x12) when the user never answers. The timer is armed
while a command is pending and cancelled on any response, equip, rescue
and card disconnect.
Also fixes docs/api.md, which had back (0x11) and timeout (0x12) codes
swapped. Tests for arm/cancel/clamping and the flat timeout TR. SW cache
v89 -> v90.
